Chapter Text

Growing up, it’s always just been Atsumu and Osamu. Osamu and Atsumu. The Miya twins against the world. They’ve cared for themselves since they can remember since their mother died in childbirth, and their father is away for work in Hong Kong more often than not. Atsumu always assumes that since they’re twins that they’ll always be together, always the same. One isn't seen without the other close behind. Though there are differences between the two boys, of course, it isn’t until they’re twelve that the first major differentiation occurs.

They’re at the age where most children begin presenting as their secondary genders, and it isn’t at all a surprise when the Miya twins come to school one day beginning to exhibit characteristics typical of alphas.

Atsumu, despite the strange abdominal pain, is especially pleased with the development. Being an alpha is so easy. They get all the benefits in life. Sure, times are changing, but living in the Kansai region, old habits often die hard. The term proper omega is still used in the west more often than you’d think. Plus, Japan is typically a fairly traditional country. Alphas, on the other hand, are often held in higher regard. To top it all off, they don’t have to deal with shit like heats. Those seem like such a waste of time.

Another thing about western Japan is that omegas are born at an extremely low rate. No one is really sure why, as the east has birth rates that compare to the rest of the world. Some say it’s a punishment from the gods because of how the Emperors of old treated the omegas in their harems, but who can really say. Then as per usual, rates of male omegas make up the smallest percentage.

A couple of weeks later in the middle of volleyball practice, the pain becomes so unbearable that Atsumu collapses. It feels like someone is repeatedly stabbing him or that there’s something trying to literally claw its way out of his abdomen. He can’t stand or uncurl from the fetal position. With sweat and tears trickling down his face from the pain, Atsumu thinks he might be dying.

Being an alpha in the middle of presenting, Osamu immediately goes into defense mode to protect his brother. It takes Suna, a medic, and their father on the phone to calm him down. Only then can they attend to Atsumu and bring him to a hospital.

Imagine Atsumu’s surprise and absolute horror when his diagnosis is that he’s actually presenting as an omega. An omega with something called pseudoalphaism. That’s the first and last time he hears the medical term for a long time.

No one talks about how painful presentation is for those of the rarest dynamics, those being female alphas and male omegas. It’s a long-drawn-out process. They literally grow and form new organs. Like holy shit. The hospital does an ultrasound and shows him where his uterus is growing. Between his and Osamu’s wide eyes and gaping mouths, he’s not sure who’s more shocked. Those hold children. Like actual human beings. Oh god. Dread builds in the pit of his stomach. Is that what he’s going to be subjected to? Is he going to be sent away to one of those omegan boarding schools to become proper?

The hospital wants to run some more tests on his status, but can’t without his dad’s signature of consent. Breathing a sigh of relief, he’s released with some pain medicine and advice for bed rest.

Atsumu begs his brother to not tell a soul. He’s an alpha. It was just a really bad stomach ache—that’s what they’ll tell everyone. Not even their dad can know the truth. He wouldn’t be able to survive at one of those stupid prep schools. He can’t be separated from his twin. Ragged breaths and cold sweat consume him as he clutches Osamu’s shirt.

The younger twin hugs his brother tight and promises that no one will take him away. If that’s what Atsumu wants, then no one else needs to know. The doctor had said that pseudoalphaism isn’t dangerous, so that’s all he cares about.

The only other person that they let in on the secret is Suna, as he’s both twins’ best friend, and they trust him. He promises to take the secret to the grave. The tone he uses is one that’s seldom heard, and they know he means it. The three are an inseparable trio. They mesh well together, especially being composed of one of each dynamic, but that’s their own secret.

It’s not until high school that Atsumu interacts with another male omega for the first time. It’s at the InterHigh, and the few he sees are beautiful and graceful or cute and small. It’s no wonder a lot of male omegas are models. When he looks in the mirror, he’s none of those things. Maybe he’s just not meant to be an omega.

Now at the prime age of twenty-two, Atsumu has been living as an alpha for ten years. He knows the habits, the subtle body language to give off in certain situations, how to influence his pheromones to smell a certain way. For all intents and purposes, he’s an alpha. This is his life.

It’s not that he’s ashamed of his true dynamic, not exactly. Over the years, he’s met plenty of male omegas that he thinks highly of. Several of them are amazing individuals and defy all odds. However, at this point, he feels like there’s no reason to go get checked out at the doctor for his condition. He’s fine. Sure, there are times it’s crossed his mind, but ultimately it’d be a hindrance.

How often would he have to take time off for heats? Would they be painful? What if he’s like those omegas he hears about that absolutely lose it? Would his omegan instincts demand that he find a suitable mate? He doesn't have time for that.

It’s not until two new members join the Black Jackals roster in April that he contemplates his options more seriously. Both of the men are familiar faces, though they have definitely changed. Hinata is your typical male omega, smooth skin, round face, smaller frame, and undeniably cute.

Then there’s Sakusa Kiyoomi, and holy fuck, he’s grown up. No longer is he this lanky adolescent alpha with a mop for hair. Nor is his strongest scent reminiscent of the cleaning aisle at the store. No, this Sakusa Kiyoomi exudes the presence of a mature, powerful alpha. Calm, collected, confident… Not to mention that he’s filled out quite well. He’s hot, okay? He has undertones of sandalwood, and he’s really fucking hot. That new hairstyle really suits him too.

When he makes eye contact with Sakusa, he refuses to succumb to stupid hormones and blush. So in typical Atsumu fashion, he winks at him with a mischievous smile. This earns him an icy glare, which really shouldn’t look that attractive when it’s directed at him.

If his inner omega was a material being, it would be rolling around in a field of flowers writhing in excitement. Even though it’s just that inner voice that lives in his head, it’s annoying. It doesn’t happen often with his whacked-out hormones, but it does make an appearance in the forefront of his mind on occasion. However, this time it’s completely unwelcome and can go right the fuck back to where it’s been hibernating.

That night at home, Atsumu looks in the mirror. He looks like the definition of an alpha. Tall, broad, sharp jawline, muscular—just naming a few. Turning his head side-to-side, he sighs. Would he still look like this if his hormones weren’t fucked up? Would an alpha actually approach him with romantic intentions?

The only people who typically approach him are omegas and female betas, and he doesn’t swing that way, unfortunately. Romance for him is a bit of a lost cause because no one can find out what he is. He’s never even been with anyone sexually because he’s terrified. One, because he’s scared of how he’ll react; and two, what if they find out the truth? The thought is literally petrifying. Like what would they do to him? Would they be mad that he lied? Would they… hurt him?

Looking ahead, his golden-brown eyes stare back at him. Why after all these years is he having a crisis about this now? Or is he just finally allowing it to break free? Atsumu has no idea what being an omega means. He’s ignored everything about his true dynamic since the day he found out the truth. Out of sight, out of mind, right?

After their first official practice, he approaches Hinata Shouyou. His inner omega is urging him to befriend another omega. In fact, it’s screaming at him. Instincts fucking suck. However, befriending Hinata is on his to-do list anyway. Sakusa… Well, that’s an entirely different story.

“Shouyou-kun! Ya gotta tell me ‘bout Brazil! What did they feed ya there? ‘Cause, damn, yer even more of a monster!”

Hinata’s tinkling laughter fills the locker room. “Well, a lot of weird spices for one. And beach volleyball really revs up the endurance!”

They continue to converse as they walk back to the Black Jackals complex together. They click easily, and Atsumu vaguely wonders if this is part of some omegan instinct thing that he's unaware of. Omegas do tend to group together. That’s a real fact that he’s totally not making up, right? Fuck. He knows nothing.

But then again, Hinata definitely has no idea he’s speaking with another omega. Why is all this dynamic shit so complicated? It’s stupid! It shouldn’t matter! Fuck instincts and hormones! Just let him live his life!

However, they don’t listen to his pleas. The more time he spends around Sakusa, the more this deep-seated urge to do something claws at him. He doesn’t quite understand what it’s trying to say. All he knows is that Sakusa is really fucking hot and a giant fucking dick.

“Miya, I swear to god, if you keep tossing the ball that high I’m going to kill you, and no one will be able to prove it.” Sakusa glares at him with beads of sweat running down his forehead.

Atsumu scrunches his nose and argues, “But ya can hit it! Yer reach is so much higher than what yer scrub of a setter was doing for ya in college.”

“Kibo was a perfectly good setter.”

“But I’m better. Now shape up, Omi-kun. Ya have so much untapped potential.”

If looks could kill, Atsumu would be six feet under. He feels a shiver run up his spine, and it’s not one borne of unpleasant feelings. Maybe he has a death wish.

Bokuto, sensing the tension, comes over and throws an arm around Atsumu’s shoulders. “How about we all go out to an izakaya tonight! Akaashi is coming to visit too!”

Akaashi Keiji. He’s one of those male omegas that’s ethereally beautiful and graceful. Atsumu once tried to get to know him but ended up being unfairly intimidated. Akaashi appraised him like he was looking for something. That gaze was unnerving, and Atsumu didn’t want to wait around for him to come to a conclusion. It’s just like he knows something and can’t wait to poke around just to see you squirm.

He kept a healthy distance away from the other omega after that. Even though he can feel eyes on him when they’re together. He’s pretty sure Akaashi is a closet sadist and enjoys the discomfort he causes Atsumu.

“Akaashi-san is coming?!” Hinata suddenly pops up out of nowhere. “I haven’t seen him in ages!”

So that’s why the four monster generation players, plus Akaashi, are sitting at an izakaya on this fine Friday evening. Atsumu is shocked Sakusa decided to join them. Apparently, university did him some good in social etiquette.

It’s actually a pleasant outing. Sakusa isn’t being unbearably prickly, and Akaashi is keeping his analyzing gaze to himself. Or rather it’s focused on Bokuto. Honestly, if those two could get their act together, it would be a miracle. Just watching Bokuto’s attempts at flirting is sad. He doesn’t seem to be picking up on any of Akaashi’s signals either. Sad indeed.

Atsumu feels those eyes on him again when Hinata leans in to whisper, “Why does Akaashi-san keep looking at you like that?”

Apparently, Sakusa has hypersonic hearing, because he quirks an eyebrow in interest. “Is he interested in you or something?”

“Ya need to get yer eyes checked if ya think he’s here for anyone other than Bokkun.”

Hinata hums in thought. “I mean, that’s what I thought, but I’ve never seen him appraise someone like that outside of a volleyball match.”

Shrugging he takes a sip from his drink. “All I know is that he kinda terrifies me a bit.”

Sakusa makes his first comment on the subject with a raised eyebrow. “Did he scare you away after you tried flirting with him?”

“What? No, of course not. I’d never do that to Bokkun. Plus, I’m not interested anyway.”

“Oh? That’s surprising,” he says with amusement.

“What’s that s’posed to mean?”

Sakusa gives him a look that says he should know exactly what he means but elaborates anyway. “You seem like the type to enjoy company.”

Hinata’s eyes go wide as he takes in the meaning, his head swinging back and forth between the two. Fully turning in his seat, Atsumu gapes at Sakusa.

“Excuse me?”

“I know a playboy alpha when I see one.”

Atsumu blinks a few times before bursting into laughter because, oh man, is he so off the mark. He’s pissed, don’t get him wrong, but it’s also fucking hilarious. He clutches his stomach trying to contain his giggles.

“What’s so funny?” Sakusa seems affronted by this sudden change in demeanor.

“You.” Atsumu smirks up at the other. “Yer pro’ly just jealous that no one comes onto ya. But maybe if ya got that stick outta yer ass, some nice little omega will take an interest.”

“You’re an asshole.” The glare he receives only elicits more laughter.

“Takes one to know one.” Atsumu stands then, ready to leave. “Well, as invigoratin’ as this conversation has proven to be, I’m goin’ home.”

After saying his goodbyes to everyone and turning, he feels two pairs of eyes on him this time.

Back in his unit, he stares at his reflection once again. It’s becoming a nightly thing, so it seems. Hm. He does give off a douchey alpha vibe. Maybe he’s overcompensating and should tone it down a bit. But then again, when has he ever really cared about what other people think?

Always. His brain supplies.

Right.

Being the “better” twin. Being the “best” setter. Being a “good” alpha. Being a “proper” omega.

Atsumu isn’t any of those things. He’s a wolf in sheep’s clothing. Trying to conform to what’s expected of him. Because why? Because he’s afraid?

What would it be like to live how he really wants to? But at the end of the day, does he even know the answer to that question himself?

Chapter Text

Atsumu has never worried about walking the streets alone in the dark. The chances of someone picking a fight with an alpha over 183 cm is virtually zero. Having nothing to fear is often something alphas take for granted. They're the strongest on the block, and they know it. There are, of course, those assholes who flaunt their power over others. Atsumu has stepped in to help some poor beta or omega more than once. It’s fucking ridiculous. Can’t people just walk with others minding their own goddamn business?

In a world where society once pandered to alphas, some find it difficult to realize that’s not the case anymore apparently. Betas aren’t just there to boss around. Omegas aren’t your plaything. These are real people just trying to get by. There’s nothing wrong with tradition, of course, but sometimes alphas use it as an excuse to be pigs. Atsumu hates squealing pigs.

Pushing open the door to Onigiri Miya, he makes his way to the counter.

“Welcome to Onigiri Miya how—,” Osamu stops his greeting as he rounds the corner, seeing Atsumu. “Oh. It’s you.”

“Now is that any way to greet yer brother who has traveled on this lonesome summer evenin’ to see ya?” He drops dramatically on one of the barstools at the counter.

Osamu scoffs, rolling his eyes. “Well, usually when ya visit, ya want somethin’.”

“Only yer opinion.” Osamu raises an eyebrow at that. Atsumu doesn’t often ask for help, and opinions often fall under that category.

“Sure, but will ya quit with yer alpha posturin’? It’s just us, and it’s annoyin’.”

Atsumu relaxes his shoulders and ducks his head sheepishly. “Sorry. Habit. But that’s kinda part of what I wanna talk about.” Osamu nods, indicating that he’s listening. “These last couple months, I’ve been thinkin’ ‘bout goin’ to get this thing checked out at the doctor.”

“I mean, if that’s what ya wanna do, I’ll support ya. Why the sudden interest though?” Atsumu’s cheeks flush, and he avoids his brother’s appraising eyes. Osamu sighs, “Please don’t tell me this is ‘cause of some stupid alpha.”

“Yer a stupid alpha,” Atsumu mumbles petulantly.

Walking around the counter, Osamu takes a seat on a stool next to him. “Ya don’t need to change for someone.”

“It’s not changin’, it’s gettin’ treatment for a medical condition.” Atsumu raises his head to look his brother in the eyes. “‘Samu, do ya think fate fucked up?”

Osamu furrows his eyebrows in confusion, searching Atsumu’s face for understanding. “What do ya mean?”

“Well, look at me!” Atsumu gestures to his body. “I look nothin’ like an omega!”

“And what’s an omega look like?”

“Beautiful, small, graceful, elegant, pale flawless skin, petite. Not— Not like me,” he finishes with a hushed voice and looking down.

Now that he’s actively thinking about exposing his true dynamic, Atsumu feels unsure of himself. As an alpha, he’s confident, and it’s like no one can touch him. But as an omega… Would he be ridiculed? Compared to the other two omegas in Division 1? He’s nothing like Hinata or Hoshiumi.

Osamu lays a hand on Atsumu’s shoulder, catching his attention. “‘Tsumu, what people think doesn’t matter. Yer an adult now. They can’t ship ya off somewhere. Plus, it’s 2018. A lot has changed in the last ten years.”

“Then why ain’t ya datin’ Sunarin, ‘Samu? It’s 2018,” he mocks viciously. Osamu retracts his hand like he’s been burned.

“Ya know we can’t. I— I haveta find a suitable mate to carry on the family line.”

“Oh cut the shit. Stop treatin’ me like I don’t know what ya do, where ya go.”

“‘Tsumu.” Osamu stands, warning in his voice and scent. However, Atsumu is never one to back down and presses on.

“How ya go to those seedy bars to find a beta man or alpha to fuck or let fuck ya.”

Osamu lunges at his brother, and they fall in a heap onto the floor. “Ya just had to say it, didn’t ya!? Make ya feel like a big powerful alpha?! Huh?! Yer just as much of a fake as I am!” He snarls, teeth bared.

They kick, punch, scratch, and bite at each other, landing several hits and only relent when Osamu finally gets the upper hand and pins Atsumu down. They’re both heaving for air with fierce looks in their eyes. However, most of the true animosity has bled out in their brawl. They both have battle wounds from the affair.

Osamu releases him and stands, offering out a hand. Atsumu takes it and stands with a slight wince. Osamu is innately stronger than him and always will be if he keeps decently fit just because he’s a real alpha. Life isn’t fair.

Retaking their seats, they slump against the countertop in silence. It’s definitely past closing time now, and honestly, they’re lucky no one came in during their spat. The entire restaurant smells of hostile alphas.

Atsumu knows that Osamu is right, but there’s so much at play, so much at risk. He’s essentially been lying about his medical records his entire professional career. Can he be kicked from the team? It’s a chilling thought. He’s sure the team would back him up—or would they feel betrayed?

It’s messy, and he’s never really known what to do, so it just keeps piling up. Is it too late to ask for help?

He’s not sure how much time has passed when Osamu breaks the silence. “So wanna tell me ‘bout it?”

So he does. For at least the next hour, they talk about Atsumu’s worries and fears. And Atsumu listens to Osamu’s as well. They’re both in a tough spot, and it’s not going to be easy to get out. However, at the end of the day, they always have each other to fall back on, someone that will love them unconditionally. It’s Atsumu and Osamu against the world, after all.

They decide on a game plan for each of them. Osamu is going to confess to Suna about his sexual preferences the next time they meet up, and then see what happens. Starting small before he confesses his feelings for the man straight out. Atsumu is going to confide in Hinata about his condition. Both twins hope that their attempts aren’t in vain.

Atsumu and Osamu had their heart-to-heart two weeks ago. Neither have yet to make good on their promises. Though Atsumu knows that Suna is coming down for Kita’s birthday next week. A few Inarizaki alumni are throwing him a party for his twenty-fourth birthday. Osamu has agreed to have it at the restaurant. There will be no escaping, and he’ll see to it that his brother holds up his end of the deal.

On his own end, things have been alright, he supposes. The new members have been with the team for about three months now and mesh well. Hinata is generally just a joy to be around, and their connection has strengthened. In Atsumu’s opinion, they’re good friends. Sakusa, on the other hand… Well, there’s still a lot to be desired there.

He finally gave in to Atsumu’s insistence on the higher toss. He tried not to be too smug when their first quick using it left everyone stunned. Actually, no, that’s a total lie. Atsumu was extremely smug.

They’re not friends, but he doesn’t think Sakusa totally hates him anymore. Honestly, it’s hard to tell. He keeps his pheromones wrapped up tight. Or maybe he just uses blockers very liberally. Either way, Atsumu finds him hard to read, though he’s learning. The eyes never lie, and Sakusa isn’t always aware of what he says with them.

For example, when Atsumu completely busted his ass and missed a receive, Sakusa’s body language said he was irritated, but his eyes held amusement. There’s hope! He’s not a total jackass! Maybe.

For the sake of his sanity, he sincerely hopes it’s true. His stupid inner omega might have a breakdown if it’s not. It’s in there, rattling metaphorical shackles and banging on walls. Like fuck. Chill. Atsumu is doing his best, but his best is apparently not good enough for that little demon inside of him. Sometimes he really wishes he could drop-kick it.

Two nights before Kita’s party, Atsumu decides that he’s going to do it. He’s going to talk to Hinata tonight. Stepping out of his unit with determination, he walks up the flight of stairs to Hinata’s floor and raps on the door.

Hinata opens with a smile. “Hey, Atsumu-san! What’s up?”

“Umm,” now that he’s here, he’s nervous, “I wanna talk to ya ‘bout somethin’.”

Hinata cocks his head but opens the door wider to let him in. He follows the other into a space that’s decently clean despite the numerous articles of clothing draped over the furniture.

Plopping down on the sofa, Hinata gestures to the space next to him. “Is everything okay? You seem serious.”

Taking the offered cushion, he sits and pulls a pillow to hug in his lap. “Yeah. I just have somethin’ I wanna confess.”

Hinata’s smile fades, and his face turns serious. “Umm. Look, I want to stop you right now if you’re about to confess your love for me or something. I’m sorry, but I’m already interested in another alpha.”

At that, Atsumu barks out a laugh. “Oh god! It did sound like that!” He wipes a tear from his eye. “No, Shouyou-kun, definitely not. Furthest thing from it, really.” Smirking at the other omega, he asks, “Does that alpha happen to be Tobio-kun?” He watches as Hinata’s face now turns beet red.

“Maybe! But we’re not talking about me!” He flails his arms around in distress. “Sorry, sorry, what do you want to confess?”

“Well, um. First, ya haveta promise to keep it a secret. Ya can’t tell anyone.”

Hinata nods and promises to keep it to himself, so Atsumu dives in. Once he starts relaying his story, he realizes how little about it all he actually knows. It’s a bit disconcerting if he’s honest.

The disorder is supposedly rare, and everything he knows is from that single hospital visit ten years ago. Does he even remember everything properly? Has new information about it come out? He could do a quick online search, but the thought is a little terrifying. What if he doesn’t like what he finds?

“Okay, so let me make sure I’ve got this right.” Hinata wiggles in his spot. “You’re an omega, but you have this gland disorder that secretes alpha hormones. And you’ve decided to just live your life as an alpha for the past ten years even though you can potentially get treatment. And now you’re thinking about it and are telling me because you don’t have any omega friends and know nothing about being an omega?”

Well, when he says it like that… “Uh… Basically.”

“That sounds awful!” Hinata flops his head back onto the couch. “But thanks for telling me.” He suddenly shoots up. “Oh my gosh! I’m actually super excited about this! I used to have a bunch of omega teammates back in high school. So I’m glad I can have one again.”

Atsumu remembers the oddity that was Karasuno when he first saw them his second year. He thinks there were at least three if not more omegas on the team. It’s practically unheard of, but Karasuno really defied the odds anyway.

“Well, I dunno how omega-like I can really be, but yer welcome?”

“Nah, don’t worry about that. Plus if you have any questions, you can ask me now! We can totally talk about alphas too.” He gasps suddenly, startling Atsumu. “Wait. So that means you don’t have a big gay alpha crush on Omi-san!?”

“Heh?” Atsumu’s lost, but Hinata just keeps talking.

“But of course you still have a crush, a crush is a crush. But now you have a chance! Omi-san seems pretty traditional, doesn’t he? I bet he really—”

Atsumu’s eyes grow round, how did Hinata even pick up on that? “Whoa, whoa, whoa. Slow down there, Shouyou-kun.”

“Ah, sorry.” he smiles brightly.

Atsumu decides that’s a conversation for another night as he’s a bit emotionally drained, and it’s already getting late. They make plans to meet up after morning practice tomorrow. Seeing himself out, he waves goodbye to his friend.

He feels lighter—like a weight has been lifted by just telling Hinata. A small jitter in his stomach makes him smile. Atsumu is actually excited about this.

“What are you doing, Miya?” Comes a deep voice in front of him. Snapping his head up, he meets Sakusa’s dark eyes. “You shouldn’t be sniffing around an unmated omega’s door this late at night.”

Atsumu scoffs at the insinuation. “Why? Ya interested?”

Sakusa’s face scrunches. “No.”

“Then why’s it matter? I can visit a friend.”

“Everything you do has an intention.”

“Ya know, ya make a lotta assumptions ‘bout me.'' Atsumu widens his stance and puts his hands on his hips, glaring at the alpha. Why does he like this asshole? Seriously. “I dunno what exactly I did to ensue this unnecessary ire from ya, but it’s gettin’ real old, Omi-kun. And anyway, what are ya doin’ out this late?”

Sakusa narrows his eyes and lifts up a bag of groceries. “I go when the stores are less crowded. You never answered my question.”

“Fine. If ya must know, I was confidin’ my woes and askin’ for his input. I in no way, shape, or form have sexual or romantic intentions with Shouyou-kun. Are ya happy now?”

Sakusa slightly lowers his eyes, not submitting, but admitting that he’s in the wrong here. “Sorry.”

Atsumu blinks a few times, thinking he misheard. “What? Could ya say that again?”

The alpha’s eyes snap back up in distaste. “I said I’m sorry. For always seeming to judge you too quickly.”

“Oh.” Atsumu’s a bit stunned. He certainly didn’t expect an elaboration. “Um. Thanks. Maybe if ya actually took the time to get to know me instead of bein’ a giant dickwad, then things like this wouldn’t happen.”

Sakusa seems to be deep in thought with his forehead scrunched up, then he sighs. “Come over tomorrow.”

“Wait, what?”

“Please don’t make me repeat myself again.”

Atsumu is a little confused, curious even. “Umm. Why?”

Sakusa sighs, rather begrudgingly. “So we can get to know each other or whatever and as an apo— fuck, do you want to or not?”

Well, this is certainly unexpected. Atsumu doesn’t think Sakusa has invited anyone over since he joined the team. There’s no way he can turn him down. That stupid itch inside him would absolutely kill him. So he accepts.

Sakusa swiftly walks past him to his apartment door after stating a rather bland “Six o’clock.” Atsumu isn’t really offended though. Sakusa is never one for much interaction, and this conversation is sure to have drained what little tolerance he has.

However, Atsumu can’t help but follow him with his eyes. There’s more to Sakusa Kiyoomi than what meets the eye; he knows this already. His calm, cool demeanor rarely cracks, but Atsumu wonders if underneath there’s a raging fire, some predatory beast that’s dying to get out. The presence he carries is intimidating, but Atsumu isn’t cowed by it. No. He’s intrigued.

No matter how much he fights it, his inner omega is drawn to Sakusa, and instincts don’t lie. It’s a truth that he’s hard pushed to admit. Why this alpha? Why now? Is his body trying to tell him something?

Feeling like he’s being pulled in three different directions, Atsumu deems that this dynamic shit isn’t even in the top five of his biggest concerns list right now. The top spot belongs to how much shit can he get into for lying on medical records. Or maybe it should be if he’s fucked up his system from not being treated for ten years. Either way, he’s set things in motion. Now, he just has to see them through.

Chapter Text

After practice, Hinata and Atsumu walk back together, just talking casually about one of their quicks. They don’t delve into deeper topics until they’re in the safety of Hinata’s apartment.

Then it’s like a flip switches in the smaller omega. He’s still all smiles, but his aura has turned serious. Hinata tells Atsumu to make himself at home while he goes to get something. Whatever this “something” is, Atsumu is kind of weary, though he shouldn’t be. He’s sitting on the sofa, tracing random patterns on the cushion when Hinata returns with a notebook.

“Alright.” He plops down next to Atsumu. “After you left last night, I was invested. So I did some digging.”

Atsumu grimaces. He himself hasn’t done any research, and here Hinata is taking initiative. “What kinda diggin’?

“Well, I started with pseudoalphaism, but it was all these medical research articles that I didn’t really understand. So then I started looking at other stuff and went down the rabbit hole and—” He stops and flips to a page in the notebook. “Well, the point is that it’s perfectly legal to hide your real dynamic in your career, but I’m not sure about the medical records.”

Atsumu feels immediate relief. Well, that’s one thing down. He’s still worried about how the rest of the team will react though. He loves playing on the Jackals. Everyone has really made Atsumu feel like he belongs here—like it’s a home. Yeah, there was Inarizaki, but there was always that lingering feeling of a few of his teammates secretly hating him. Don’t get him wrong, he loves the friends he made there, it’s just not everyone understands his drive, his passion.

Here though, they understand. Every single person here has the same wants and desires. Atsumu meshes with them, and they’ve helped him better himself as a person since high school. The Jackals accept him as he is. Atsumu doesn’t want to let that go.

Hinata continues, “So I called a friend.”

Atsumu chokes. “Ya what?!”

“Calm down. I didn’t say any specifics. Have a little more faith in me, Atsumu-san. And if it makes you feel better, he’s an omega that used to pose as a beta.”

It’s not that he doesn’t trust Hinata, but he doesn’t trust whoever this friend might be. Chances are they know Hinata is talking about a real person in the volleyball circuit and not just asking out of pure curiosity. Although with them being in a similar situation—sort of—they’re less likely to say anything.

“Well, what did they say?”

“He said he’d get back to me on it. Lemme check.” Hinata pulls out his phone and starts tapping away on it. “Nothing yet, but I’ll let you know!” He tosses his notebook on the coffee table and turns to Atsumu in interest, smiling with his elbows on his thighs and fists under his chin. “So, tell me about Omi-san.”

Atsumu groans, leaning back onto the couch. However, he indulges his friend.

From the first time he saw Sakusa again after all these years, it triggered something in him. He’s not completely sure what it is, but something inside himself feels different. Maybe it’s the revival of his inner omega that remained buried and pushed to the side finally standing up and saying, “I am here.” An instinct clawing its way through the stone walls Atsumu has built to keep it contained for ten long years, raising up to shout out the suppressed truth of it all.

Then there’s also the deep-seated fear that he’s managed to ignore once again terrorizing the smallest crevices of his mind. It’s like a heavy darkness obscuring his vision of what lies right in front of him, pressing on each of his most vulnerable insecurities that have suddenly surfaced.

Atsumu dares to hope that he himself has that same strength his inner omega does—hopes that he can light up that darkness and fight for what he truly yearns for.

And what is it that he wants? Atsumu wants to stand on his own two feet and be able to proudly declare that he’s an omega. To stand exactly where he does now, playing as starting setter for the Division 1 team MSBY Black Jackals with his friends. To be accepted as he is despite his flaws and shortcomings.

Right now he’s at the bottom of the mountain looking up at the tallest peak. It’s going to be a difficult climb, but Atsumu is nothing if not determined. Though he might need a little help when his footing falters, he’ll look over that peak and into the horizon of what lays beyond.

And maybe, just maybe, Sakusa Kiyoomi might be among that horizon. He's an entirely different mountain in the distance though. Even if he could be considered the catalyst, this whole omega thing was probably inevitable in the end.

“I think you’re on the right track, Atsumu-san! But you aren’t going to say anything to Omi-san about it now?” Hinata asks after Atsumu has rambled on for god knows how long.

“No way! We ain’t even friends. Yet. I’m goin’ over to his apartment in a bit,” Atsumu says, checking the time.

Hinata smirks impishly at him. “Oh yeah? He invited you over? When no one has ever been graced with stepping foot in his home?”

“Oh, c’mon. He thinks I’m an alpha. It ain’t like that.”

“I’m just saying, I think he would appreciate you being honest.”

“Well, it’s not like he’s ever asked. No one has. They take one whiff of me and immediately go alpha.” Atsumu huffs, crossing his arms. It’s not his fault people assume things. Don’t ask, don’t tell. That’s how it’s always been. Even if Hinata’s right, because Sakusa would appreciate the honesty, Atsumu isn’t ready yet.

“That’s true. I’m guilty of it, too.” Hinata flops back on the couch.

They sit there in a comfortable silence for a while, just processing their conversation. It’s nice having someone to talk to about all this. Sure he has Osamu, but this is different. There’s something about another omega’s comradery that feels comforting. He wonders if it would be even more different if he was a normal omega.

Hinata breaks the silence to ask when Atsumu is going to the doctor; and isn’t that the big question?

Somehow Hinata bullies him into calling to check availability. And oh, look at that, they just had a cancellation, and he’s now slotted for a consultation two days from now. Two days. Oh fuckfuckfuck. The only reason he gets through the phone call is due to Hinata’s calming pheromones and comforting hand holding his own.

“You did it! You should be proud of yourself. This is a big step, Atsumu-san.” Hinata squeezes his hand before letting go. Atsumu tries to calm himself and reign in his anxious scent. Even though Hinata hasn’t said anything, he can tell it’s not pleasant by the small scrunch of his nose.

“Thank ya, Shouyou-kun.” He smiles at his friend. “I really appreciate all yer help.”

“No problem! Oh! You should probably get going so you aren’t late.”

Atsumu nods, getting up and heading to retrieve his shoes. Hinata sees him out with a “Have fun!” Then he’s walking just a few doors down the hall.

He’s not really sure what to expect. Sakusa’s invitation was unexpected, putting it lightly. Somehow he feels there’s a reason behind it, so what the hell is it? Guess there’s one way to find out.

Rapping on the door, Atsumu doesn’t have to wait long before Sakusa opens it. The alpha’s lip curls. He doesn’t even offer a greeting and just says, “Stay there.” and walks away.

Atsumu, not knowing exactly how to take that, stays put more out of confusion than anything else. Does he look bad? Smell bad? He pulls up the collar of his shirt to take a sniff. Smells fresh and clean to him. Then Sakusa returns with an aerosol spray. Oh lord. Atsumu prepares for the inevitable of what’s about to happen.

“You smell like Hinata, I’m going to spray you with scent blocker.” He doesn’t wait for a reply before dousing Atsumu in it. “Turn around.” He does, and he’s sprayed again. “Alright. Now you can come in.”

While taking off his shoes he asks, “What’s wrong with Shouyou-kun’s scent? I think he smells fine. And ya never seem to have a problem at practice.”

“I don’t want an unmated omega’s scent lingering in my home. It’d make me anxious.”

Atsumu hums in understanding. It’s a thing with some alphas regarding their homes. Sometimes it’s because of the feeling of their territory being invaded, a reaction to an omega they have no intention to mate with, or simply because they’re sensitive to smells.

“Yer nose real sensitive?” Atsumu is pretty sure this is the reason. Him never being able to smell Sakusa at practice would make a lot more sense if he uses suppressants and blockers to help with the scents.

Atsumu has never had to take suppressants. His sense of smell is rather weak. Somehow he feels that it’s related to his condition. How would it be if he were normal? Would everyone smell different? What would Sakusa smell like? Right now Atsumu can only pick up undertones of sandalwood. It’s only now that he realizes how highly unfortunate that really is.

Atsumu relies on scent cues often. They can tell a lot about how a person is feeling, especially when they don’t say. Atsumu has always been one to pay attention to other people and take care of them, even if it doesn’t seem that way. He has his own methods. Even if it’s just taking away Bokuto’s stash of gummy vitamins that he thinks he can just eat like fucking candy. It’s his responsibility as setter to make sure all his hitters are in top condition after all.

“Not any more than the average person’s.”

Atsumu furrows his brows. He was sure that was it. “Then why do ya use so many scent blockers and such?”

“Not that it’s any of your business, but it was recommended by my doctor. When I was younger, I was prone to bouts of extreme aggression, and I’ve been told that my scent is rather potent as it is. So I take a small dose of suppressants.” With that, he walks into his kitchen.

Sakusa? Extremely aggressive? The fact that he kind of wants to see that is rather concerning.

Once he’s done spreading some sanitizer on his hands, Atsumu makes his way in to look around. So this is Sakusa’s place. The no man’s land of the Black Jackals complex, the final frontier. Of course, it’s immaculate, but it’s not quite as barren as he expected. There are a couple of house plants over by the window and a bookcase filled with hardbacks and… is that a record player? On the TV stand is a PlayStation 4 set up.

Just taking in this bit of information, Atsumu feels like he understands the alpha just a bit more. These hobbies fit him. He chuckles at the thought of Sakusa making some kid cry over voice comms.

Drawn by the smell of food, Atsumu pads his way into the kitchen where Sakusa is cooking something. Raising an eyebrow, he takes in the scene. Sakusa, slouched in front of the wok with one hand stirring the contents and the other on his hip. Well, here’s another thing to add to his list of things he never thought he’d see.

His mind runs wild. Sakusa turning to smile at him, looking at Atsumu with love and affection. The tingle of a mating mark on his nape, reminding him of their promise. A little stutter in his chest at the thought of a future that looks just like this is a strange sensation. The tug of his heart at an alpha providing is such a foreign concept to him. But, of course, that’s not what this is; he has to remind himself. Sakusa is not an alpha trying to court him. Atsumu is not… an omega.

“Omi-Omi, whatcha makin’?” Atsumu leans against the counter, observing.

“Yakisoba.”

“Yer cookin’ for me? So ya do have manners, I’m touched.” He dramatically clutches his chest.

Sakusa turns his head to look at him with a deadpan expression. “I was trying to be a good host, but now I think you’ll just have to starve.”

“Hmph. Well, forgive me if I’m a little skeptical of this sudden invitation. Ya say I have an agenda, but yer the one who never does somethin’ without a reason behind it. So c’mon, out with it. Why am I here?”

Rolling his eyes, Sakusa turns off the burner and grabs two bowls out of the cabinet before answering. “I promised Motoya that I would try to make… friends.”

Atsumu gives him a disbelieving look, raising his eyebrows. There’s more, he knows it. Yes, Komori is a meddling little shit; he’s heard stories from Suna, but Atsumu also knows Sakusa doesn’t give two fucks. There’s dirt here.

Sighing, Sakusa continues, “He threatened to tell my mother that I’m not ‘adjusting,’ and the last thing I need is for her to come down here in a panic and worried about me.”

A small smile tugs at Atsumu’s lips. Even though Sakusa’s words don’t seem all that soft, he can tell that the alpha cares about his mother very much. It’s endearing that he’s pushing himself out of his comfort zone to not worry her.

Sakusa hands him a bowl of the yakisoba and they sit down at the small table against the wall. “So ya chose me?”

“Well, you already know why I don’t want Hinata in here alone, and I’m not sure how long I can listen to Bokuto wax poetic about Akaashi. Plus, I’m already familiar with you.”

“I guess that makes sense. I just thought that ya kinda hated me.”

Sakusa looks up at him with furrowed brows. “I never… hated you. There’s just something about you that really pisses me off, and I don’t know what it is.”

Atsumu takes that statement with a grain of salt. He pisses a lot of people off, but usually, there’s a definite reason. Somehow he feels that whatever this is, there’s more to it because Sakusa doesn’t actually seem pissed at Atsumu. It looks more like he’s struggling with something internal and being an asshole to Atsumu is his outlet. Those aren’t the eyes of a hostile alpha. They never really have been.

“Well, if ya ever figure it out, I’m dyin’ to know. What could I have the great Sakusa Kiyoomi so baffled about?” He smirks at the glare the alpha sends him.

When they finish their meal, Atsumu helps Sakusa with the dishes and cleaning the kitchen. They banter back and forth, but it’s playful, nothing like it usually is. Sakusa even smirks! Like that’s real progress. Maybe they actually can be friends. It was only a matter of time before Atsumu’s charms won him over anyway.

Then after Atsumu makes a comment about Sakusa actually being into things other than volleyball, they end up playing some game on the PS4. Sakusa doesn’t bother teaching him how to play, and Atsumu struggles to keep up. He’s not good at this stupid game, and Sakusa is being an asshole. But when Atsumu notices a small upward lilt on the other’s face, he supposes he can deal with it just a bit longer.

However, when he gets spawn killed a third time in a row, he’s done. “Alright ya asshole,” Atsumu lays his controller aside and points an accusing finger at Sakusa, “I’m done.”

“You could have just asked me to stop.”

This smug jerk. Atsumu crosses his arms and pouts. Stupid, dumb, attractive alpha. Why? Why did it have to be this guy?

They’ve actually been playing for longer than they thought, so Atsumu decides it’s best to head out. As he opens the door, he looks back at Sakusa. “Ya know, Omi-kun, we should do this again.” He nods, and Atsumu smiles at that. Omi Nods say a lot if you know what to look for, and Atsumu thinks that he does. “Goodnight, Omi-kun.”

It’s been happening a lot more often lately—those nights where Atsumu lays in bed and tosses and turns. The kind of nights where everything runs through his mind at a pace he can never keep up with, where all his thoughts spin and swirl to the point he can’t discern what’s real anymore.

The worst times are when the thoughts tangle with his dreams, dressing them in the figures of the people he loves the most—who lash at him with sharp words that cut him right to the bone. Where he trembles in fear and wakes up with a start, panting and drenched in a cold sweat. Where he staggers to the bathroom to splash water on his pale face and looks in the mirror and wonders if what those nightmare versions of his friends say are true.

Last night was one of those nights. So when he walks into Onigiri Miya, the dark circles under his eyes are extremely prominent. His concealer is shit apparently. No matter how much he puts on, he still looks like a damn panda. Atsumu isn’t late by any means, but there are already people here.

Suna approaches him, poking at his cheek. “You look like shit.”

Atsumu bats his hand away. “Well, nice to see ya too Sunarin.”

“So who’s this unfortunate alpha you have the hots for?”

“My no-good brother already tell ya everythin’?”

“Yep.” Atsumu rolls his eyes. Of course, Osamu told him. They act like a fucking old married couple.

“He talk to ya ‘bout anythin’ else?”

Suna cocks his head slightly. “Like what?’

“That piece of shit.” Atsumu marches his way over to the counter where Osamu is placing onigiri on a platter and proceeds to chastise him about blabbing to Suna about all his shit and then not even holding up his own end of their promise.

Osamu shushes him and glances at Suna, who is playing on his phone with a bored expression. “I’ll talk to him after the party, ‘kay?”

“Fine.”

“By the way, ya look like shit.”

The party is a nice reunion. Atsumu hasn’t seen everyone like this since high school, and they’ve all really grown up. Of course, he sees Aran when they play against each other. He also keeps in contact with Suna, and there’s the occasional time he’ll see Kita here at the restaurant.

Looking at Kita, Atsumu wonders why it couldn’t have been him. Why isn’t Kita Shinsuke the alpha that awakened whatever this is? He’s accepting, patient, kind, dependable, handsome... Atsumu nursed a healthy crush on his captain back in high school, but who can blame him? Sure Kita isn’t the flashiest alpha, but just his mere presence is enough to suppress any doubt of his worth.

No, instead it’s Sakusa Kiyoomi. The prickliest damn person he’s ever met. Though after yesterday, Atsumu thinks that maybe his inner omega chose him for a reason. Underneath his rough exterior, Sakusa is much softer than he would have thought. Smiling softly to himself, he can’t help but hope for the best.

“Is everything alright, Atsumu?” Kita asks, taking the seat next to him.

“Kita-san!” Atsumu snaps out of his silly daydreams. “Sorry. I was just lost in thought. Are ya havin’ a good time?”

The alpha smiles softly, looking around at his former teammates. “Yeah. I can’t believe y’all put this together for me.”

“It’s just somethin’ to show how much we appreciate ya. And to repay ya for how much grief we all put ya through.” Atsumu smiles at him. God, they were all such little shits.

Kita chuckles and ruffles Atsumu’s hair, making him blush. The scent of a light breezy, earthy tone lingers around him. Again, Atsumu wishes his sense of smell wasn’t complete shit. He’d love to be able to bask in the calming scent that Kita gives off.

Atsumu decides to leave when the majority of the others do. That way Osamu and Suna have ample time to talk. He makes eye contact with his twin, a pointed look on his face. Osamu nods. The ass better actually do it.

Arriving back at the complex, he sees Sakusa dressed to go on a run.

“Omi-kun!” he greets with a smile.

Sakusa scrunches his nose in distaste. “What the hell is that? You smell like you’ve been prancing around in a rice field.”

“What?” Atsumu sniffs himself. “Oh! That’s probably Kita-san. I think he smells nice. Ya don’t?”

Without his mask on, Atsumu can see how the alpha’s mouth grimaces slightly. “No.”

He shrugs in response. To each their own. “Have a good run, Omi-kun!” With that, Sakusa glances back at him before jogging off.

Atsumu stares after him in wonder. Sometimes the alpha just doesn’t make sense. For someone not sensitive to smells, he sure seems to have a problem with a lot of them. Really, how could he think Kita smells bad? No one else has ever said that. In fact, most say that he smells just like the country air of Kobe, which is pleasant. Figures city boy over here wouldn’t like it.

Atsumu is about to call it a night since he needs to be at the doctor’s office in the morning when he gets a text from Osamu.

Samu
I did it.

You
Good. And???

Then he has an incoming call.

“What is it, ya loser?”

Words tumble through the speaker. “He said he likes alphas and other beta men too.”

Atsumu raises his eyebrows in surprise, sitting on his bed. “Oh shit. Wait, why’re ya callin’ me then?”

“I said I needed to use the toilet.” Osamu sounds slightly embarrassed and Atsumu snorts in amusement.

“And ya call me a dumbass.”

“Shut yer trap. I didn’t think I’d get this far.”

“Well, ya can just tell him how ya feel.”

“I don’t know. Fuck. I need to go back out there. Call me after yer doctor’s appointment, ‘kay?”

“Alright, I will. Good luck, ‘Samu. Love ya~” He teases with a lilt, though he means it.

Atsumu can hear the eye roll in his voice. “Yeah, yeah. Ya too.”

Ending the call, he sets his phone on his nightstand and flops back on the bed. He’s nervous about tomorrow. What will the doctor think? Will they judge him? Blame him for this situation he’s gotten himself in? What if it can’t be fixed after all? What if he can’t be normal?

Atsumu digs his fingers into the sheets at the thought. He’s never worried about that before. What if he’s stuck like this forever? No one would ever want him. He’s defective, right?

Trying to push the anxious thoughts away, Atsumu crawls under the covers. It looks like he’s in for another night of restless sleep.

Chapter Text

Atsumu shakes his leg as he sits in the waiting room. He knows that he probably looks shifty. He’s at an omega specialist and reeks of alpha, a distressed one at that. No one is sitting anywhere near him or attempts to make eye contact. The receptionist had side-eyed him, and he really hopes that they won’t throw him out.

He’s trying to stay still, but his shaking leg has a mind of its own. Now that he's here, Atsumu feels so unprepared. Today he’s going to find out about this disorder or disease or whatever that has haunted him for ten years. That really makes him sound dumb, doesn’t it?

A nurse calls his name, and Atsumu sees the flash of confusion when he stands, but she leads him to a room anyway. He follows her stiffly and is just as awkwardly as she takes his height, weight, and vitals. So now he sits on the exam table with that annoying crinkly paper, twiddling his thumbs.

The room he’s in has quite a few posters of various omega health subjects, but Atsumu thinks at this point it’s just better to wait. He’s too far removed from everything omega and is basically starting from scratch. This is actually going to suck, isn’t it?

After a while, a middle-aged beta woman with glossy black hair tied in a bun knocks and walks into the room. “Hello, Miya-kun. My name is Dr. Yoshiba,” she greets, sticking out her hand.

Taking her hand he says, “Nice to meet ya. Just Atsumu is fine.”

“Well, Atsumu-kun, I called your regular practitioner that you gave us, and they were quite confused as to why an omega clinic was asking for your medical charts. After reading them and seeing you, I can definitely see why. So what brings you in today?”

Atsumu looks into her kind green eyes and sees no amount of judgment. “I have pseudoalphaism. And um, I think it’s finally time to do somethin’ ‘bout it.”

Dr. Yoshiba takes a seat in her swivel chair, watching him. “Pseudoalphaism is pretty rare. When did you receive this diagnosis?”

So Atsumu dives into his spiel once again. The more he talks, the more stupid he feels for not knowing anything more. However, the doctor just writes down notes and is attentive.

“There has been a lot more research done on pseudoalphaism in the last ten years, and there are actually two types. Tell me, what are your cycles like?”

Atsumu blinks at her. “My… cycles?”

“Have you ever had a heat before?” He shakes his head no. “It appears you have Type II then. The good news is that we can get this all sorted out. Are you okay with getting some blood work done today?”

Atsumu nods. He’s not sure he wants to ask what the bad news is. Maybe there isn’t any. But this means he can be fixed, right? He can be normal now?

After his blood is taken, Dr. Yoshiba explains what this disorder entails. Apparently, it’s an endocrine disorder with exocrine involvement. A gland disorder. A little gland in his brain called the pituitary is sending the wrong signals to his scent glands and reproductive glands.

“Biologically you’re an omega, but physiologically, your body is saying you’re an alpha,” she says.

Basically, Atsumu is an omega, but all his omega parts aren’t working because his body thinks he’s an alpha. At least, that’s what he thinks Dr. Yoshiba means. Then she starts asking him about his sex drive. And Atsumu shouldn’t be embarrassed to admit that he’s a virgin, but well, it’s not like he’s ever really said it out loud. And apparently masturbating only once every other week is considered a “low sex drive” for someone his age. Well then.

“Do you ever insert anything into your vagina?”

Atsumu’s mind short circuits. “My what now?!”

The last time he checked, he most definitely did not have a vagina. Atsumu is pretty sure he would have noticed that.

So he gets a short anatomy lesson on male omegas which are incredibly unique according to Dr. Yoshiba. She pulls out a diagram and shows him and… Oh god. What the fuck? What the actual fuck?! He has a… No…

Atsumu stares at the diagram, trying to will the image away. It doesn’t work. He’s still looking at this… vagina.

This is how Atsumu learns that male omegas have a vagina and a clitoris. He’s in shock. Apparently, there’s this wall of tissue that separates the rectum from the vagina. At rest, it keeps the vaginal opening closed. During arousal, the vagina enlarges, which pushes the wall to seal the rectum. This opens the vagina as well. Oh, there’s that little clitoris located internally, just a little bit below the prostate. Okay. Sure. Yeah. Cool. Atsumu is one hundred percent freaked out right now, but he’s also… intrigued.

He’s less interested in all the poking and prodding Dr. Yoshiba is doing. She wants to examine him. So here he is on his back, naked from the waist down with his feet in stirrups. To say that the feeling of someone’s fingers wedged into his… vagina… when he’s not aroused is unpleasant is putting it mildly. He’s not producing slick properly, so it’s dry as a fucking desert in there. So not only does he have a vagina, he has a crusty one. Great.

Then she hits on a topic that Atsumu is worried about… Has he fucked up his body?

“Going untreated for ten years can cause complications. For instance, your height and build could be related. Of course, this may not be true as there are several omegas with a similar build as you without the disorder. What I’m more concerned about is your bone density and your fertility, especially if you plan on having children in the future.”

Atsumu collects his thoughts for a moment before asking, “What do ya mean by that exactly?”

“With these alpha hormones in your body, it can cause osteopenia or if severe enough, osteoporosis. And this disorder can also lead to infertility.”

Weak bones?! Infertility?! Wait, wait, wait. He can’t have weak bones! He’s a professional athlete! And infertility?! Oh god, what has he done? He’s fucked up. He’s a defective omega. No alpha will ever want him, let alone Sakusa Kiyoomi.

Dr. Yoshiba’s voice breaks him out of his thoughts. “Atsumu-kun, would you like to take a break? Do you want to call someone?”

He realizes he’s been emitting strong pheromones unconsciously. “Yeah. My brother.”

She advises him to do that if he thinks it may help. Atsumu rushes outside and dials Osamu. He picks up after two rings.

“Hey, how’d it go?”

“‘Samu,” his voice comes out strangled, “I fucked it all up! Oh god. I’m gonna be alone forever! And I have a fuckin’ vagina!”

The omega woman walking into the clinic gives him a wide berth at his little outburst.

“Whoa, whoa, whoa. Calm down. What’s goin’ on?”

Atsumu feels like he can’t breathe. His chest tightens and he feels a bit light-headed. He should have asked Osamu to come with him. Why did he let his pride get in the way? He knew this was going to be hard. “I… Can ya come to the omega clinic?”

“Yeah. Yeah, I’ll be there. Umm. Rin’s still here, so I’ll—”

“Bring him too!” Fuck. Atsumu needs his best friend too.

There’s a slight pause. “Okay. Give us fifteen minutes.”

It’s not until Atsumu hangs up and calms himself that he realizes Suna should definitely not still be there. Unless his stupid brother confessed everything and it worked out. He smiles to himself. He’s glad.

True to his word, Osamu and Suna show up fifteen minutes later. Atsumu drags them back to his exam room, letting the receptionist know he’s back. Then he fills them in on what he’s learned so far.

Osamu seems somewhere between disgust and shock. “Gross. But it kinda makes sense if ya think about it.”

Suna glances between the two twins. “You guys seriously didn’t know that?” When he receives blank stares, he sighs. “You’re both idiots.”

When Dr. Yoshiba returns, greetings are exchanged and the appointment continues. She hands Atsumu a pamphlet that they typically give to omegas when they first present. This will probably come in handy. He supposes that he really should educate himself better.

“I’d like to start you on a medication that’s going to block the production of alpha hormones. You’ll have to take this for three months before we can begin replacement therapy for omega hormones. Dealing with hormones is a delicate process.”

She goes over the timeline with them. First, he will start losing his alpha scent, and his senses will become muted over the three months. Then when he starts replacement therapy, things will start to really change. Dr. Yoshiba goes over it all, but Atsumu is so overwhelmed he only picks up certain words. Fat redistribution. Muscle loss. Estrous cycle. Mood swings. Sensory changes.

And then there’s the elephant in the room. The fact that only one other person than those currently present knows that Atsumu’s an omega.

Dr. Yoshiba wants to help him as best as she can and tells him what she can do. While Atsumu was diagnosed at age twelve, it’s never been input into any of his medical charts so it’s technically undocumented. However, she will have to send the updated reports to his team physician. That’s when everything can go south. So does he bite the bullet and come clean immediately, or does he wait a little bit longer?

He decides it’s best to at least come clean to Coach Foster. After that, well, he’ll just play it by ear. Osamu says he’ll be by his side when the day comes, and Atsumu only cries a little bit.

Dr. Yoshiba smiles at him warmly. “This is very brave of you, Atsumu-kun. You should be proud of yourself.” And well, if he cries and hugs the doctor too, who can really blame him?

Atsumu is set up with monthly check-ups and a new prescription before he’s sent on his way. He’s completely overwhelmed, but somehow he also feels lighter. This is the start of a whole new chapter of his life. Atsumu is going to give it his all like he does with everything else. Now he just has to wait and see what happens next.

“Hey,” a fry hits Atsumu’s cheek, “stop thinking so hard.”

Atsumu turns to see Suna about to throw another and Osamu snatching up the fry that nailed him. “Just got a lot on my mind, ya know?”

Osamu sends him a neutral look. “Ya look like a deranged cat.”

“Alright, fine. Let’s not talk ‘bout me then.” He smirks at the two sitting in the booth across from him. “Let’s talk ‘bout y'all. Why were ya still with my brother this mornin’, Sunarin?”

Taking a drink of water to give them a moment proves to be a bad choice. Here he thought he was giving them a bit of mercy.

“We fucked,” Suna just nonchalantly throws out.

Atsumu chokes and spits water on the table, droplets roll down his chin. “What the fuck?! I don’t wanna hear ‘bout what ya and my brother do in the bedroom!”

“You asked. Besides, you think I wanted to hear about your crusty vag?”

Osamu gives them both a disappointed expression.

When Atsumu arrives back at the complex, new medication in hand, he feels content. Both Osamu’s spicy clove and Suna’s muted patchouli scents cling to him. They mix together, making this warm feeling sink into Atsumu. The two go together well, and it’s just another affirmation that they belong together.

Heading to Hinata’s door, Atsumu is let in after knocking. Once he’s collapsed on the couch, he recounts his doctor’s visit. Hinata laughs, doubling over at his freak out on the discovery of his genitals.

“Wow, Atsumu-san! You’re really missing out! You should definitely invest in some toys. Oh! Let me show you my favorite.”

Atsumu gets a little light-headed at the sight of this massive dildo Hinata brings out. He puts that inside himself?! Dear lord. This is too much. He needs a moment. Maybe his libido is abnormally low after all.

Hinata pats him on the shoulder and apologizes for teasing him, though he’s still giggling. Honestly, Atsumu can’t really even blame him for it. Once Hinata calms his giggles, he promises Atsumu that he’ll be here when he’s ready to start asking more questions. Atsumu feels relief and is eternally grateful for his friend. Where would he be without him?

Apparently, practice this morning was a spectacle. Atsumu had already informed Coach Foster he wouldn’t be there, and of course, Hinata knew; but the rest of the team wasn’t aware. Sakusa seemed extra irritable when no one revealed why Atsumu was absent.

Hinata smirks at Atsumu as he recounts the story. He tries to pretend that his stomach doesn’t swoop at the mention of the alpha. Valiantly he tries to tell himself that it’s not because of Atsumu per se; it’s just that their main setter wasn’t there, and it peeved him. That’s what would make the most sense when Sakusa is involved.

However, when there’s a rapid knock on his apartment door that evening, Atsumu can’t help hoping it’s Sakusa. Though he’s met with an empty hall when he opens it. Scenting the air, he can’t discern who it was. Frowning, he retreats back inside. That was weird.

Atsumu sets his new pill bottle on his nightstand. He takes his first dose tomorrow, first thing in the morning. It’s crazy that those tiny little tablets are going to help fix him. To think that in three months he’ll no longer smell of cinnamon spice. He’ll be starting all over, relearning everything. Or can he just stay as he is?

This is just the tip of the iceberg. For all that he sees, there’s so much that lays deeper, submerged in the darkness below. When Atsumu jumps off and plunges headfirst into the freezing water, will he survive? Or will the icy chill cling to his bones and drag him further down into the abyss? Perhaps he’ll drown.

In the current that pulls Atsumu along, he’s tumbling and thrashing to reach the surface. Everything is an unknown. How many rip tides will suddenly appear, hold him back, and leave him too exhausted to continue?

Tomorrow is just the start.

After practice the next day, Atsumu tells Coach Foster that there’s something important that he needs to discuss with him. He sees Hinata lingering, sending him an encouraging smile. Atsumu nods his head, thankful for the concern. Clutching his doctor’s notes in his hand, he follows his coach to his office.

Foster is, of course, shocked but not angry. He tells Atsumu that this has a very low possibility of hampering his current position unless it affects his performance on the court. His shoulders sag, finally relaxing. It’s a huge relief.

They discuss when to inform the rest of the team, and it’s decided that Atsumu has until the season starts to tell them. Atsumu knows that he should probably tell them sooner rather than later, but a part of him is scared of the resentment and betrayal they may feel. It’s selfish and misleading, and Atsumu hates that. But he can’t bring himself to say anything right now.

To his surprise, Hinata is waiting for him in the locker room. “How’d it go?”

“Good, actually.” He smiles at the smaller omega. “Now I just haveta tell the team.”

“Well, I’ll be beside you when you do!” Hinata loops his arm with Atsumu’s, making him laugh. “Oh! And my friend got back to me. His boyfriend works for the Volleyball Association and said that internal matters such as this would be left to the discretion of those involved.”

Atsumu ruffles Hinata’s hair. Maybe things won’t be so bad. They walk arm-in-arm back to the complex. Neither notice the eyes that follow them the entire time.

“Miya.” Atsumu bangs his head on the top of his locker in surprise. He turns to Sakusa, rubbing his head. The alpha has a dark glower on his face.

“Jeez. Ya don’t haveta be so snappy. What is it, Omi-kun?”

“Come to dinner with me.” It’s not a question.

Atsumu wills his heart to settle down and cocks his head. “Uh, okay. Sure, but only if ya get that scary look off yer face. What’s the occasion?”

“I thought you said we should hang out again.”

There’s a stampede in his chest, and he’s pretty sure it’s being orchestrated by his inner omega. It’s shaking his heart violently, making it stutter and leap. Sakusa is actually initiating this? Again?

“Kiyoomi-kun, why are you asking Atsumu to dinner when there is a line of cute omegas vying for your attention?” Inunaki teases.

Atsumu steels his face, showing no reaction. He knows Inunaki means nothing by it; he thinks Atsumu is an alpha. But he can’t help immediately thinking it means he’s not cute. Is Atsumu cute? No… Probably not.

Sakusa curls his nose. “I’m not interested.”

Bokuto leans on the lockers nearby. “Why not?”

Hooking a mask behind his ears, Sakusa eyes his teammates. “Omegas are so delicate. I feel like I’m going to break them.”

Thankfully, Atsumu’s choking noise is covered by Bokuto’s and Inunaki’s howling laughter. “Hinata, did you hear that!”

Said man walks around the corner locker chuckling. “Sure did! Don’t let Hoshiumi-san hear you say that. He’ll go feral. Us omegas are much sturdier than you give us credit for.”

“Well, I have yet to find an omega I’m even remotely interested in. Volleyball is my priority right now.”

Atsumu can’t think, he’s lost the ability. He might be going mad because all that occupies his brain currently is the image of Sakusa Kiyoomi wrecking him. And it’s a startling realization that this is the first time he’s ever had a thought like that.

“Are you ready, Miya?”

His mind snaps back into focus, and he adjusts his hair one more time. “Yeah!”

Sakusa leads him to a yakiniku restaurant and orders a platter of assorted meats for them to share. It feels intimate. Like a date. This isn’t a date. That’d be weird. Right? Alphas don’t date each other. Well, Osamu would. Sakusa would have specified, right? He said, hang out. Bros go to restaurants together. He and Suna do shit like this all the time. If he wasn’t so damn enthralled by the man, he wouldn’t be questioning this.

Laying his first piece of beef on their charcoal grill, Atsumu decides to break the silence. “So yer not into omegas?”

Sakusa glances up at him, and Atsumu hopes his face isn’t giving anything away. “That’s not… exactly it. I’ve just never met someone that captures my interest. I tried dating an omega girl in university. It obviously didn’t work out. Same with a beta girl.”

Atsumu braces himself for his next question. “Have ya ever considered a male omega?”

“Yes, but I find that I’m rather picky.” He waits for Sakusa to elaborate, which he doesn’t. “Why the interest in my dating life?”

“Ain’t that what friends talk ‘bout?” Good cover me. He praises himself.

Sakusa gives him a small smile, and Atsumu pinches himself. Nope. That’s completely real. He’s so handsome, it’s driving Atsumu insane.

“I suppose so.” Sakusa pauses and seems reluctant as he asks, “What about you? You’ve been sneaking around a lot lately.”

“I’m not seein’ anyone if that’s what yer askin’. And I don’t do casual things like ya’ve implied before.” He takes his beef off the grill and inspects it. Perfectly cooked. That’s right, Osamu isn’t the only Miya that knows how to cook.

It’s been about a month since his first doctor’s visit. Atsumu can already tell a difference in his senses. His sense of smell is even duller, and his own scent is muted. And Sakusa already seems suspicious of something. Atsumu hasn’t been “sneaking around” or whatever. He’s just been spending a lot of time with Hinata, Osamu, and Suna. Plus. he’s been learning about omega things. Atsumu’s just been busy! Why is Sakusa always on his case?

“I’ve been known to be wrong on occasion.” Sakusa’s phone dings and he sighs with a fond look in his eyes when he checks the message. “My mother is ridiculous. She’ll ask if I’m eating okay and in the next sentence ask when she’s getting a grandchild. Is yours like that?”

“My ma actually died givin’ birth to ‘Samu and me.”

“Oh. I apologize for assuming.”

Atsumu waves him off. He’s just glad Sakusa isn’t giving him pitying eyes. Though he’d be the last person to do so. Atsumu knows how he feels about pity. “It’s fine. I ain’t torn up ‘bout it. It’s always just been ‘Samu and me.”

Sakusa’s brows furrow. “What about your father?”

“He’s away for business in Hong Kong most of the time.” Atsumu shrugs. Miya Yoshirou is a good man. He works hard to support his family, even after taking the loss of his mate extremely hard. Atsumu then realizes that he hasn’t told his father about what’s going on. He feels guilty for hiding this from his father all these years. Will he still love Atsumu?

“I can’t believe you and Osamu have just been looking after yourselves like that. I— Hey are you okay?” He notices Atsumu’s distress.

“Yeah, sorry. I just realized I needta tell my dad somethin’. Don’t worry ‘bout it.” He smiles at Sakusa. The alpha doesn’t seem convinced but leaves it be.

The rest of dinner is pleasant. Atsumu makes Sakusa smile and even laugh once. He has dimples! Atsumu’s heart swoons. He’s so charmingly handsome, and it makes Atsumu’s stomach flutter.

The entire time, his own smile doesn’t fade. Every moment he spends with Sakusa, the more Atsumu realizes that he actually likes him. It’s not just his inner omega calling out for Sakusa’s alpha. Atsumu likes Sakusa Kiyoomi as a person. If he’s given the chance, there’s no denying that Atsumu could definitely fall in love with him. It’s a bit terrifying, but with hope blooming in his chest, it’s hard to not want to see where it goes.

Sakusa pays for both of their meals without batting an eye and ignores all of Atsumu’s protests. Friends don’t do that, do they?

Before they part ways, Sakusa stares at Atsumu like he’s searching for something. Those dark eyes linger on his face, but he eventually huffs and heads up the stairs. Atsumu isn’t sure what to make of it.

Letting himself inside his apartment, he takes off his shoes and settles onto the couch. It’s time to have a long-overdue conversation with his father. Should he have Osamu come over? He’ll at least let him know. He shoots off a text to him.

Samu
Wait for me.

Atsumu snorts at his twin. He’s so overprotective sometimes. Atsumu isn’t going to fall apart, but he does appreciate the support. He’d be completely lost without Osamu. What a sorry sap he is.

His brother arrives still in his Onigiri Miya shirt and cap. When they’re sat next to each other, side to side, Atsumu dials Miya Yoshirou’s number and puts it on speaker. Hong Kong is only an hour behind, but he should be home from the workday.

“Hello?”

Atsumu smiles hearing his voice. “Hey, Pa. Osamu is here too.”

“Hey.” Osamu greets with little enthusiasm.

Their dad’s chuckle rings in the air. “How’re my boys?”

“We’re good. But uh, there’s somethin’ I needta talk to ya ‘bout.” Osamu places a hand on Atsumu’s bouncing leg.

“Is everythin’ okay?”

“Yeah, it’s— ” Atsumu can already feel himself getting emotional.

“Atsumu? What is it? Ya know ya can tell me.” His dad’s worried voice comes from the receiver.

“Pa, I’ve been keepin’ somethin’ from ya. I— I have somethin’ called pseudoalphasim.”

“Are ya sick? I’m not familiar with that term. What does it mean?”

“It means that I have fucked up hormones that make me appear as an alpha. But I’m not… I’m… I’m an omega.”

There’s a pause on the other end. Atsumu grabs Osamu’s hand as he waits with bated breath. “Is this a disease? Are ya okay? Ya ain’t hurt, right? Atsumu, why didn’t ya tell me?”

The flood of questions surprises him. All of it is in concern for Atsumu’s well-being. There’s no anger at all. So Atsumu tells his dad everything with Osamu chiming in on occasion.

“Atsumu, why didja feel like ya had to hide this from me?”

Atsumu sniffs, trying to keep those stupid tears at bay. “I was scared. I didn’t wanna be sent away.”

“Atsumu, my boy, I would’ve never sent ya away. I love ya no matter what dynamic ya are.”

At those words, the damn breaks. He starts sobbing and leans on Osamu’s shoulder, who is also shedding a few tears. “I— lo-love ya too, Pa.”

Osamu talks to their father a bit more as Atsumu is too busy trying to contain his emotions. He’s crying happy and sad tears. Happy because his dad accepts him as he is and sad because maybe he could have been living a normal life years earlier. He’s so stupid. Why is he so stupid?

Osamu stays over and covers Atsumu in his calming pheromones. He hasn’t been scented by his brother in a while, and he’s forgotten how safe he feels. They both crawl into Atsumu’s bed and snuggle close like they used to when they were little.

Sometimes Atsumu needs to remember how much some people truly care for him— that it’s okay to ask for help, okay to lean on someone else. And here with his twin’s warm presence next to him, he thinks that he’s learning.

Chapter Text

When Dr. Yoshiba said that his senses would become suppressed towards the end of therapy, Atsumu didn’t think it would feel like this. Atsumu can’t smell anything. He doesn’t have a scent anymore either. He feels so off-balance, and it’s making him anxious. The world around him seems foreign. It feels like he’s walking in a void, and it’s scary.

It’s a real hindrance for someone that has used scent their entire life for vital information. Even his hearing and eyesight are affected to an extent. Neither feels quite as sharp as usual, and he’s worried about how this will affect his volleyball.

Thankfully, Osamu has been staying over more often than not for the last week. If his brother scents him, it helps ground Atsumu. Just the feeling of knowing there’s a familiar scent on him calms his nerves. It’s some innate reaction to kin he supposes. The science of it all eludes him.

The season is starting soon, and Atsumu’s three months of medication coincides with that almost perfectly. He’s running out of time.

It’s becoming obvious there’s something going on with Atsumu. Sakusa is more skeptical than ever, and he’s running out of excuses. Atsumu knows that he needs to just tell the team, but he’s scared. Specifically, he’s scared of Sakusa’s reaction.

Sakusa has previously stated that he doesn’t feel comfortable with an unmated omega in his living space. Will he think Atsumu abused that knowledge and betrayed his trust? What if he doesn’t want to be friends anymore? Atsumu being a familiar alpha to him was one of the main points of striking up their friendship. Why is Atsumu so stupid? Why did he ever think this would be a good idea?

It all comes to a head when Sakusa confronts him in the locker room after practice one day. “Miya, why can’t I smell you?”

Atsumu turns to face Sakusa. He’s been extra prickly lately. The aura he radiates has put the whole team on edge. However, now it’s just the two of them in the locker room. Atsumu had lost track of time in the shower, lost in his thoughts.

“I, uh—” Atsumu doesn't want to lie anymore. So he makes a decision. “I— I’ll tell ya with the rest of the team tomorrow.”

“Does this have to do with why you’ve been sticking around Hinata so much and coming in reeking of some alpha?”

Atsumu furrows his brows. “Some alpha? Ya mean ‘Samu?” Sakusa’s dark aura suddenly lets up, and his face turns impassive. “What’s yer deal? Ya’ve been actin’ weird.”

Sakusa looks to Atsumu with confusion written in his eyes. “I... don’t know.”

“Well, figure it out, Omi-kun. Ya’ve been scarin’ Shouyou-kun.” Atsumu closes his locker and strides past Sakusa, who is still standing there. He stops to say one last thing but doesn’t face Sakusa. “Oh and just so ya know, I uh… I’ve really enjoyed gettin’ to know ya these last few months. I hope ya can forgive me.”

Atsumu hears Sakusa shift in his direction, so he makes a beeline outside. He’s not ready for whatever conclusion Sakusa will draw from that. He’ll find out with everyone else tomorrow, and if he still wants to talk afterward, Atsumu will listen.

Guess it’s time to tell Osamu, Hinata, and Foster that tomorrow’s the day.

Atsumu, Osamu, and Hinata walk into the gym early today. Coach Foster is waiting for them in his office. Atsumu thinks it’s probably a good thing he has no pheromones to give off because they would be heavy in the air with a putrid scent.

None of them say much. Most of what happens will depend on the team’s reaction. Though Hinata has told Atsumu that he thinks it’ll be better than he expects. He truly wishes those words eased his mind.

When the time comes, the four of them walk out together. The team is in the middle of warming up as Coach Foster calls for their attention.

Bokuto is the first one over. “There you guys are! Oh, what’s Mya-sam doing here?”

“I, um, have somethin’ I needta tell ya.” Atsumu feels Hinata hold his forearm, and Osamu rests a comforting hand on his shoulder. Looking at the team, Atsumu can see their perplexed and worried expressions. “I’m sorry for keepin’ it a secret, I was just scared.”

He pauses to take a breath. The gym is completely silent. Atsumu feels his heart hammer in his chest, and his hands turn clammy. He thinks he might pass out. Scanning his teammates’ faces, he settles on Sakusa’s calm, dark eyes before saying, “I’m an omega.”

Atsumu sees Sakusa stiffen, so he turns his gaze away to see other people’s reactions. Bokuto looks like he’s deep in thought, Inunaki stares at him in disbelief, Thomas shrugs, Barnes raises an eyebrow, and Meian speaks.

“I think I speak for all of us when I say I’m confused.” The team nods.

So Atsumu, once again, tells his story. He sincerely hopes he doesn’t have to tell it many other times; it keeps getting longer.

Bokuto appraises him with his owl-like eyes. “You know, that actually explains a lot.” Atsumu isn’t really sure how to take that. Then Bokuto beams at him and says, “I’m glad you finally told us, Tsum-Tsum! We’ll be here to support you through it, right guys!”

The frigid atmosphere melts as he’s met with positive replies. The only person who has yet to say anything is Sakusa. He’s just standing there, staring at Atsumu like he’s grown a second head. While Atsumu feels relief at his team not being angry, he can’t help but worry over Sakusa’s reaction—or lack thereof.

After practice, Atsumu is prepared for another confrontation but none comes.

That night, Atsumu’s mind consumes him. Staring in the mirror, all he can think about is how disgusted Sakusa must have felt. How he let Atsumu in his home, trusted him, befriended him, this disgrace of an omega. What must he think? Now that his “alpha” friend is a sad excuse of an omega, what will become of their friendship? Now that Sakusa knows that Atsumu lied all this time, he’ll want nothing to do with him.

Examining his sharp and angled features, there’s no way any alpha would ever look at him in interest anyway. Atsumu isn’t normal, he’s not desirable. No one would want to stick around, especially when they find out that he might be infertile. No alpha wants a barren omega. What’s his purpose then?

“‘Tsumu, I can feel ya overthinkin’ in there. Get yer ass in here and go to sleep.”

Atsumu huffs a laugh. Even without his pheromones leaking out everywhere, Osamu always knows. He claims it’s a twin thing, and Atsumu is inclined to agree. With one last glance at his reflection, he turns out the light.

The day has finally come for Atsumu’s appointment to start hormone replacement therapy. Osamu is here with him. Suna is coming down tomorrow for their birthday but has demanded an update call afterward anyway. It’s strange to suddenly have all these people so concerned about him. The team knows he has an appointment today, but they won’t ask for details, except for Hinata. He’s an exception.

Sakusa still hasn’t talked to him off the court. Atsumu can’t get a good read on him. Hinata says that he keeps staring at him when Atsumu isn’t looking, but that could mean several things. The behavior is just bizarre. It’s like he’s just watching Atsumu. He doesn’t seem angry or even upset about the whole thing. To an extent, it’s a relief; however, this whole watching from afar business makes Atsumu feel like he’s in a nature documentary.

“Atsumu-kun, Osamu-kun, it’s good to see you again. Are you ready for today?” Dr. Yoshiba greets them.

Atsumu nods with a smile. He’s nervous, but excitement thrums in his veins. He’s going to receive an injection of omega hormones every two weeks. If he responds well it might become monthly. There’s even a small chance that the hormones will stimulate his omega system to start producing the hormones itself. If that doesn’t happen, it’s something that he’s going to have to take for the rest of his life. While it’s not a perfect outcome, Atsumu doesn’t really mind it. It could be so much worse.

Dr. Yoshiba says that he should start noticing effects in as little as a month. Larger changes will become noticeable in three to six months. This is when he should expect his first heat as well.

“Heats affect everyone differently, but there are a lot of misconceptions about them. You’re not going to lose complete control over yourself as some people think. I’d also like to go ahead and start you on birth control.”

Atsumu blinks at her. “I’m sorry, what?” Osamu closes his eyes and looks like he wishes to sink into the ground.

“I’m not insinuating that you’re going to engage in sexual intercourse immediately, though I’m sure you will at some point. I’d like to start it to help begin regulating your cycle. Adding some progestin may help with stabilizing your omega as well.”

So that’s how he adds another injection to his list. Thankfully, this one is only every three months. He’s given the first dose of both of them today.

“There’s one other thing you should be aware of about this first heat. I’m not going to lie to you, Atsumu-kun, since your pseudoalphaism has gone untreated this long, your first heat is going to be extremely vitriol.”

Atsumu does not like the sound of that. “How bad are we talkin’ here?”

“The pain is subjective, but from what I’ve read it’s described as sporadic spasms that feel like an electrical shock among other symptoms.”

Atsumu pales. Maybe this isn’t a good idea after all, but it’s too late. Why the fuck did she not say that before he got the shot?

“Is there a way to relieve the pain?” Osamu asks.

“Not completely, but there are some things that will help.”

Dr. Yoshiba goes on to explain a bit about it. Of course, sex helps to an extent as with any heat. Pheromones of trusted individuals and what an omega would use for a normal heat. So basically nothing. Great.

Atsumu considers himself to have a pretty high pain tolerance, so maybe it won’t be as hard as he’s expecting. However, when he voices this he can’t help but notice Dr. Yoshiba’s strained smile.

Walking out of the clinic, he turns to Osamu. “Thanks for comin’ with me, ‘Samu.”

“Of course. Plus, I needta know this stuff too. Someone hasta make sure ya take care of yerself.”

Atsumu rolls his eyes. “Yeah, yeah. I have plenty of alphas tryin’ to mother me on the team already.”

“Speakin’ of alphas, has Sakusa gotten his head outta his ass yet?”

“No,” he huffs and crosses his arms. “Ya’d think I gave him the plague or somethin’.”

A small smile tugs at Osamu’s mouth. “I still can’t believe he’s the one yer all gaga over.”

“I am not ‘gaga’ over anyone.” Atsumu uses air quotes on the word. “I just think he’s kinda neat.”

“Neat,” Osamu deadpans.

“Oh, fuck off! Ya know what I mean!”

“I can’t wait to tell Rin ya called yer crush ‘neat’.” Osamu laughs at him, clutching his stomach. Atsumu groans.

It’s not like Atsumu expected to immediately feel different, but there’s nothing. And he knows that changes don’t happen overnight. So when he looks in the mirror, he’s not sure why he’s so disappointed to see his familiar face reflected back at him.

He’s twenty-three today. Suna is taking him and Osamu to the mall this afternoon. It’s kind of a tradition. The three of them fuck around window shopping, eat at the food court, and he and Osamu pick something out for their birthday courtesy of Suna. It’s always a good time, but this will be the first year that Atsumu will essentially be third-wheeling. Atsumu tries not to think about what activities his brother and best friend will be getting up to tonight.

Hinata’s the first to greet Atsumu at practice. His wide toothy smile beams up at him. “Happy Birthday, Atsumu-san!”

The joy radiating from Hinata is infectious and he smiles back. “Thanks, Shouyou-kun.”

“Do you have any plans?”

Atsumu nods. “‘Samu, Suna, and I are goin’ shoppin’ this afternoon.”

“That sounds like fun! What about tonight?” Hinata asks in a sly tone.

“Nah.”

“Hm. Well, maybe something will come up.” He glances over to the side before returning his attention to Atsumu. “I’m gonna go warm up now!” Then he skips out to the gym. Weird.

He turns around and is surprised to see Sakusa standing there. Damn muted senses. “Uh, hi, Omi-kun.”

“Miya.” He nods in greeting.

They both stand there in awkward silence. Atsumu crosses his arms with an expectant look and waits. It looks like Sakusa has something to say, and he’s not going to help him out. Sakusa is the one that’s been acting weird, so he can be the one to grow a pair and say what he has to say.

Sakusa opens his mouth, then closes it. He furrows his brows, thinking hard about something it seems. “Happy Birthday,” he says before power walking out to the gym.

Atsumu stands there confused. Was that really it? That’s all he wanted to say? It couldn’t have been, right? At least he didn’t seem angry.

On the way home, Hinata asks, “So what are you doing with Omi-san tonight?”

“Uh, nothin’?”

“You mean he didn’t ask you out?!” Atsumu shakes his head, confused. Hinata grabs his hair in exasperation. “Gah! Why are alphas so stupid! I gave him an in and everything!”

Atsumu chuckles at Hinata's frustration. Though he wonders if that was Sakusa’s initial goal. All Atsumu wants is for Sakusa to just do something. This waiting game is killing him. Can he just either be a big boy and apologize or tell Atsumu to fuck off?

His inner omega is just as restless. It’s like it’s pacing around in circles inside of him. There’s a worn path on the carpet. Hinata’s right, alphas are stupid.

“Do ya wanna try somethin’ on over there?” Osamu asks.

Atsumu quickly turns his head away from the clothes. “No.”

Suna raises an eyebrow. “Are you sure? That’s like the third time I’ve seen you gaze longingly at it.”

They’re referring to the omega clothing line on the other side of the store. It’s a luxury brand that’s meant to extenuate all of an omega’s best features. Atsumu obviously doesn’t own anything like it. He’s had no need for something like that. However, he’d be lying if he said that when he sees other omegas in beautiful clothes he doesn’t feel envious.

“Maybe I’ll just look,” he says.

Atsumu looks through the clothing racks and tries to imagine himself in them. It’s hard to envision. Everything is so small and delicate looking. Is there even anything in his size?

“Here, try this.” Suna brings over a flowy, silk shirt.

It’s a maroon color. He likes it but— “Sunarin, there ain’t no way that’s gonna fit me. Do they have a bigger size?”

“Uh,” Suna hesitates, looking at the shirt then at Atsumu. “I’ll check.”

Atsumu knows that there’s not. He loves how supportive Osamu and Suna are being about this whole thing, but they don’t need to force it. However, Atsumu ends up in the dressing room with a few items anyway.

Staring at the clothes that Suna and Osamu shoved at him, he’s not sure where to start. So he just grabs what’s on top. It’s an immediate no when he fears he’ll rip it if he lowers his arms. Another shirt doesn’t cover his entire torso, and it’s not meant to be a crop top. This one looks extremely unflattering, and don’t even get him started on the pants. Stopping at the thigh, not buttoning, too short. Even the skirt Osamu managed to sneak into the pile doesn’t work. It barely covers his ass.

Is he too fat? Is that the issue? Atsumu turns sideways to look at himself in the mirror. Or is it just that he's too big? Why does nothing fit right? Why can’t he wear beautiful clothes like other omegas?

Frustrated, Atsumu tries to take off the shirt he has on and ends up getting stuck. It’s too small, and he doesn’t know where to put his arms. Why won’t it just come off?!

Feeling tears prickle his eyes, he sinks down on the ground. Head and arms still tangled in the shirt, Atsumu tries to curl in on himself. This is so embarrassing. He sniffs, trying to hold back from crying.

“‘Tsumu? Are ya okay? Ya’ve been in there for a while.” He hears Osamu outside the stall.

“‘Samu. Help,” he chokes out in a small voice.

Osamu swiftly pulls the curtain aside and kneels down next to him before helping get the shirt off. When he sees Atsumu’s watery eyes, he pulls him into a hug. He silently cries into Osamu’s shoulder with his body shaking.

He feels another presence settle next to him and knows it’s Suna. Atsumu feels him gently rubbing his wrist on his exposed skin, leaving his calming scent on Atsumu’s body. Slowly, he’s able to calm down.

Raising his head, he looks at the two of them. “I’m sorry. I dunno why I’m like this.” Now they’re all worried about him. Atsumu’s gone and ruined their birthday too.

“Hey, it’s fine. Don’t worry ‘bout it. Let’s go get somethin’ to eat, yeah?” Osamu says, stroking his hair.

Atsumu huffs a small, watery laugh. Osamu’s answer to everything is food. Though he’s not totally wrong.

Suna pokes his cheek. “I’ll buy you some of those gross American dogs that you like.”

Atsumu grabs both by the head and pulls them in, trying not to start crying again. He loves them so much.

That night after Suna and Osmau have dropped Atsumu back off at the complex, he walks up to his floor to find a gift bag in front of his door. He picks it up and carefully pulls away the tissue paper to reveal the cutest fox plushie he’s ever seen. He buries his face in it, trying to find a scent, but of course, his muted senses are still fucked. Atsumu isn’t sure who left it, but he has his suspicions.

Smiling, he unlocks his door and goes inside, clutching his fox close. Setting his shopping bag on the counter, he pulls out his present from Suna, some baking equipment, and finds a spot for them in his kitchen. He’ll probably make something for the team before the official start of the season next week.

Settling in on his couch, Atsumu places the fox on his lap and plays with its ears. Whoever left him this seems to not want to be identified. So maybe it’s okay to think that it’s from Sakusa. To pretend that he left Atsumu a stuffed animal filled with his scent to comfort him. It’s okay to indulge in a little make-believe, right?

The Adlers vs Jackals match is in two weeks; Hinata has been buzzing about it for the past month. Thankfully, Atsumu is slowly getting his senses back, so he should be in top form in time for the match. The changes have been pretty subtle, but today as he enters the locker room, different smells bombard his olfactory system. It’s a bit overwhelming, and he has to stop to take in his surroundings to regain his bearings.

Warm citrus and floral notes are immediately identifiable as Hinata, as he zooms up to Atsumu. “Atsumu-san, I can smell you today!”

Atsumu’s eyes widen, and his heart beats faster. Does that mean he has an omega scent now? “What do I smell like?”

Hinata scrunches his nose like an adorable bunny. “Hm. I’m not sure how to describe it. But it’s really nice!”

“Jasmine,” comes a deep voice from behind him along with the distinctive scent of sandalwood.

Atsumu shivers as the baritone reverberates through his body. Holy fuck. Sakusa has always had a nice voice, but now it’s like it’s on steroids. And his scent. Atsumu turns to face him and meets those onyx eyes. They hold some foreign emotion buried within.

Bokuto, who is standing nearby, comments, “Yeah! You’re right! Akaashi really likes jasmine. It’s a very exotic, rich scent. You’d better be careful, Tsum-Tsum. A lot of alphas call a scent like that intoxicating.”

Atsumu knows he’s only half-teasing. He and Bokuto have been pretty good friends for a few years now, so he knows there’s a light undertone of warning.

“Eh, I’ll be fine. I doubt anyone will approach me anyway.” Atsumu waves him off.

Sakusa holds his gaze for a moment longer before he turns away. The two of them are back to normal now, Atsumu supposes. Sakusa apologized for acting strangely and took him for dinner again. It’s become a weekly thing. They banter like they used to, and Sakusa seems strangely unbothered by Atsumu’s omega dynamic. It’s been nice.

However, now that Atsumu’s scent has manifested, things may be different; though Atsumu can’t help feeling giddy at finally having a normal omegan scent. What else will these changes have in store?

Chapter Text

Walking down the hall, Atsumu comes upon an interesting scene. Hinata and Kageyama appear to be squaring up. Atsumu knows that Hinata is going to express his interest to Kageyama tonight, but Atsumu also knows how dense the alpha is. He can’t imagine him and Ushijima on the same team. Hoshiumi must be even more unhinged. Wanting to get a feel for the situation, he approaches. Maybe he can play wingman.

Atsumu leans an arm on Hinata’s shoulder. “Whoa, there, Tobio-kun. Ya ain’t pickin’ a fight already are ya?”

Kageyama glares at him, and one side of his mouth pulls back. However, before he retorts, the rest of the monster generation joins them one by one. Ushijima and Sakusa strike up a conversation about the impending game, and Kageyama still looks like he’s going to bite Atsumu. Interesting.

Hoshiumi narrows his eyes, looking Atsumu up and down. “What’s your deal?!” He points a finger at Atsumu. “You smell like an omega!”

Hinata grabs Atsumu’s arm. “That’s because he is one!”

“HEH?! You mean to tell me that there’s been another omega in Division 1 this whole time?! And that I’m not even the tallest?! Everything is a lie!” He throws his hands up in the air.

Atsumu and Hinata laugh at his outburst. Now Kageyama is just staring at him with furrowed brows. Everyone seems to be taking it in stride at least. Even Ushijima acknowledges him.

“It’s good you felt comfortable revealing your true dynamic. Japan is not always the kindest to omegas.”

“Ya almost sound like yer talkin’ from experience there, Ushiwaka,” Atsumu says.

Ushijima nods and smiles slightly. “Yes. My boyfriend did not feel comfortable living as an omega until he left the country.”

Ushijima has an omega boyfriend in another country?! Just how many of these guys have been living under the radar?

“Oh! And I’ll introduce you to my friend Tsukishima! He’s the one I told you about.” Hinata smiles brightly at him.

“Akaashi is here too!” Bokuto has those ridiculous heart eyes. Actually, maybe he’s the one Atsumu needs to play wingman for because this is just ridiculous.

On the court, the tension between Hinata and Kageyama is palpable. Atsumu feels like he’s witnessing some sort of mating dance. Honestly, it may as fucking well be. Even back in high school, Atsumu remembers the dynamic between the two—there was nothing else like it. The attitude of just knowing, demanding, believing that the other would do what was expected struck something in Atsumu. While he had said that Hinata didn’t trust Kageyama but rather expected him to perform, Atsumu doesn’t think that’s quite it. There’s something more, something innate. Instinct.

Some people believe in true mates. It’s one of those old folk tales that people eat up in romance movies and novels. It’s never been scientifically proven. But if there is such a thing, Atsumu thinks Hinata and Kageyama are it. They’re always drawn to the same flame. No matter how far apart they go, somehow they always come back together.

True mates are a nice notion, but what are the chances of actually finding them? There are billions of people in the world. It seems a bit far-fetched. Though who doesn’t dream of it?

Atsumu sets the ball to Sakusa and watches him fly up into the air. Watches as he spikes the ball down, scoring a point. Atsumu feels his heart stutter. If true mates are real, how would you know you’ve found them?

Post-game interviews are always an ordeal. Everyone is hyped up from the win, and the last thing they want to do is stand still and answer questions. Especially when reporters ask about something that has nothing to do with the match.

“Atsumu-senshu, we’ve had sources tell us that you’ve recently come out as your true dynamic of omega. Do you have anything you’d like to say about these claims?”

He should have expected this. Although he’s not sure how the press got this information, it was bound to happen eventually. Can’t keep shit to yourself when you’re a public figure.

“They’re true.” The reporter looks like the cat who caught the canary. This scoop is obviously huge.

“Why did you hide it all these years?”

“I didn’t hide it. I was never asked about my dynamic.” Half-truths are always the best way to go. As much as he wants to snap about what this has to do with volleyball, he can’t. This is being broadcast live. PR would absolutely destroy him.

“But you always exuded the aura of an alpha. Why is that?”

Stay calm. It’s fine. Just answer a few more questions. “I actually have a medical condition that causes that.”

The reporter looks shocked at the revelation. “Oh. Could you tell us a bit about that?”

Before Atsumu can give another vague answer, Sakusa is at his side. “I apologize, but Miya is needed for our team debriefing.”

He guides Atsumu away with a hand placed at the small of his back. It’s warm and his skin tingles where he touches. What would it feel like on his bare skin?

“There’s no team debriefin’, is there, Omi-kun,” he says. Sakusa shakes his head with a slight smirk. “Thanks.”

Atsumu looks down with a secretive smile. Usually, it’s him rescuing Sakusa from the press. Guess it was time he repaid the favor. Atsumu can still feel the warmth long after Sakusa’s lingering hand is gone.

Several members of both teams go out to a local izakaya. Atsumu doesn’t come to Miyagi other than for games like these, but it’s not too bad. He’s sitting at a table with Hinata, Akaashi, Hoshiumi, and Tsukishima. He supposes it really is true that omegas band together. It’s an interesting experience talking with a bunch of omegas. Atsumu has never been on this side of the conversation before.

“I always knew there was something off, I just couldn’t quite place it. Now it all makes sense,” Akaashi says.

He no longer seems quite as intimidating, but Atsumu definitely doesn’t want to get on his bad side. Not too far away, he can see both Kageyama and Bokuto glancing over on occasion. They’re not subtle.

“Tsukki, you still haven’t bonded with Kuroo-san?” Hinata asks.

“No. I know he wants to… and I do want to, but I’m nervous about it.” He fidgets with the glass in front of him.

When Hinata had introduced Atsumu to Tsukishima Kei, his first thought was whoa. Not the most articulate thing, but he’s different than Atsumu was expecting. Tall—even taller than himself. He’s striking. Any room he walks into, he’d demand attention. However, there’s no denying he’s an omega. The softness in his face and his lean form translate that. Also, there’s no mistaking his strawberry scent for another dynamic.

The short conversation they had earlier was a bit enlightening. He too was insecure about his status and body type but in his third year of high school, he found enough confidence to forgo the facade of being a beta. Yes, he did experience some ridicule, but Tsukishima said the support he had outweighed anything irrelevant people said.

He’s also the only one at this table with a boyfriend, so he must be doing something right. Kuroo is over there with the idiots, but his lingering gaze is open and unapologetic. Apparently, he’d been trying to court Tsukishima even when Kuroo thought he was a beta. Atsumu sighs at the thought. It’s kind of romantic, isn’t it?

“What is it you’re afraid of, Tsukishima-kun?” Akaashi appraises him.

“What if he decides he doesn’t want me anymore? Bonding is forever for omegas. He could leave me.”

“Bite him back!” Hoshiumi says and chomps his teeth in Tsukishima’s direction. “Don’t let some pussy-ass alpha have that much power over you!”

Reciprocal bonding is a lot more common nowadays. Before, only omegas bore a mating mark, meaning they can never be bonded to another, while an alpha can bond more than one omega. However, the same is for an alpha who bears a mating mark. It’s an equal trade then. A true partnership—forever.

Akaashi nods at Hoshiumi’s words. “He’s right. And you and I both know he would show it off with pride.”

Tsukishima blushes and continues playing with his fingers. “I’ll think about it.”

Atsumu then turns to Hinata, deciding he’s next in the hot seat. “So when’re ya gonna confess to Tobio-kun?”

“You know what? I’m gonna do it right now!” Hinata says before downing the rest of his drink and slamming the glass on the table. “If I don’t come back, don’t look for me.”

Hoshiumi roars with laughter as Hinata heads towards the table of alphas and motions for Kageyama to follow him. Atsumu suspects that he most definitely won’t be back.

“And what about you, Akaashi-san?” Tsukishima raises an eyebrow. “When are you going to be up-front with Bokuto-san?”

When Atsumu sees Suna at the bar alone, he excuses himself to join his friend. Looking around, he spots Osamu talking to some guys he thinks are Karasuno alums. Then he slides into the open barstool next to Suna.

“What’re ya doin’ over here by yerself?”

Suna glances at him out of the side of his eye and sighs. “I saw an omega flirting with Osamu earlier, and I guess I’m just feeling insecure.”

“Did he flirt back?” He shakes his head. “So ya decided to sulk over here by yerself?” Suna shrugs and takes a drink of his beer. “Christ, Sunarin. My dumbass brother pro’ly thinks he did somethin’ wrong.”

He sighs again. “I know.”

“Trust me, he ain’t gonna go for any omega. Now stop bein’ stupid and go over there and stake yer claim!”

He smirks at Atsumu before he gets up. “Thanks for harassing me.”

The seat isn’t empty for long before someone else occupies it. “Can I buy you a drink?” It takes Atsumu a moment to realize that the person is talking to him. He turns to see an alpha man with slicked-back auburn hair looking at him.

“Uh, sure.” He’s not going to turn down a free drink.

“You’re not from around here, are you? I’m sure I would have noticed an omega as exotic looking as you before.” He smiles at Atsumu.

Is… Is he being hit on right now? Because exotic looking? Really? That’s not a compliment, bud. “I’m from Osaka.”

The bartender places their drinks down, and the alpha continues to try and chat him up. Atsumu is polite but obviously not interested. Like he’s giving very short answers, not elaborating on anything. How is this guy still finding things to talk about?

Atsumu turns his head to try and find someone to come save him when he feels a hand on his arm. “Is everything alright? the alpha asks.

However, the hand is quickly removed when a heavy presence approaches them. “Miya.”

“Omi-kun!” He pops out of the bar stool with a bright smile and holds onto Sakusa’s shirt sleeve as he’s led away.

“Who was that?”

Atsumu shrugs. “Dunno. Just some guy. Why? Ya jealous or somethin’?”

He’s obviously joking, no matter how much he wishes it were true. Sakusa is a straightforward guy. If he felt the same draw Atsumu does, he’d have said something by now, right? His inner omega refuses to feel dejected though.

“And what if I am?” Sakusa turns to him, his eyes unreadable.

Atsumu blanches. What? His inner omega perks up, giving him the confidence to tease. Looking Sakusa up and down he says, “Then maybe ya should actually do somethin’ ‘bout it.” He smirks, leaving a stunned Sakusa as he walks off to rejoin his previous table, feeling awfully smug.

The sight that greets him is… interesting. Tsukishima leans against Kuroo’s side, looking like he might fall asleep. Hoshiumi is shouting at Inunaki, who is sitting at a different table. Then there’s Akaashi Keiji sitting on Bokuto Koutarou’s lap with an adorable pink blush.

“Well, well, well. What do we have here?” He takes the seat next to Hoshiumi.

“I finally confessed to Akaashi!” Bokuto says, squeezing said man who only gets redder. Fucking finally.

At practice on Monday, Hinata rushes up to Atsumu to show off his claiming mark. An omega can only be bonded during their heat and alphas during their rut. A claiming mark is essentially a bite mark on the mating gland given at a time the omega is not in heat. It will fade over a month. It shows intent. Damn. Kageyama bit all three. There’s one on the nape of the neck and one on both sides between the neck and shoulder. Only biting one is necessary to bond, but possessive alphas tend to go all out.

Hinata also shows him the golden cuff bracelet on his arm with Invincible engraved on it. Damn. Kageyama really went all out. Traditionally, alphas would present a courting gift to their intended omega to show their interest. It’s not done as often anymore, but it’s a romantic gesture.

What kind of gift would an alpha present to him? Does he have suitors? That one alpha did approach him. Was Sakusa serious about being jealous? Maybe Atsumu is just turning into a hopeless romantic.

The rest of November passes uneventfully. Sakusa never makes a move over his supposed jealousy. Of course, he was just teasing Atsumu. Now he feels kind of dumb for flirting with him. Or maybe he should actually step it up a notch. Maybe he doesn’t want to come on too strong. Yeah. That’s what Atsumu will tell himself.

In early December, Atsumu has his check-up appointment and is getting his second dose of hormones. When he goes to get ready, he notices that his pants fit a bit… differently. Sure he hasn’t worn these in a while, but the waist should not be loose and his ass and thighs should not be that snug. Did he gain weight? But that doesn’t make sense. Or does it? He has been eating a bit more recently… He’ll find out at the doctor’s today, he supposes.

He’s apparently lost weight. What the hell? However, Dr. Yoshiba tells him that his changes are normal, though the rate they are happening is a bit unusual. It’s possible he’s being influenced by the number of alphas he’s around every day. Or if there’s a particular alpha he is interested in, his body might be trying to compensate.

She also tells him she can see a bit of a difference in his face as well. So naturally, he whips out his phone and turns it to selfie mode to look. Examining himself, Atsumu thinks his face looks a bit softer, and his skin is smooth to the touch. He smiles to himself. The changes are actually noticeable!

Dr. Yoshiba warns him that with this influx of hormones, he may be more susceptible to mood swings and triggers to his arousal and to not be alarmed if he starts producing slick. And with this rate of change, he should also be aware of pre-heat symptoms starting earlier than anticipated.

So things are happening fast. That’s good, right? Sort of. It means the possibility of more side effects. Atsumu can’t help but think that his omega’s pull towards Sakusa is at play here.

During practice later that day, he completely flubs a serve. Bokuto laughs at him and says he’s better than that. And Atsumu knows he’s joking. He knows Bokuto would never intentionally do something to upset someone. He’s said much worse to Atsumu before. But for some reason, he can’t control his tear ducts and bursts into tears.

“Oh shit! I’m sorry, Tsum-Tsum! I didn’t mean it! I was just joking!” Bokuto rushes over and flails around, not knowing what to do.

“It’s fine, Bokkun. I— I dunno why I’m cryin’,” Atsumu says through sobs.

Hinata hugs Atsumu and releases his calming pheromones. The rest of the team stares, completely lost. Except for Sakusa, who pushes Bokuto out of the way and embraces Atsumu.

Atsumu is so shocked he instantly stops crying. Hinata has released him, so it’s just Sakusa comforting him with that heavenly scent. He smells so good. Atsumu just wants to bury his face in his scent gland, but that might be pushing his luck.

“Are you good now?” Sakusa asks. Atsumu nods and practice resumes.

After practice, he’s fresh out of the shower when he sees Sakusa’s shirt folded neatly on the bench. It’s the one he was wearing during practice. And Atsumu’s not sure what possesses him, but he puts it on before throwing his jacket over it. Then he dresses as normal.

When Sakusa returns and questions the whereabouts of his shirt, Atsumu just zips his jacket up higher. No one needs to know that Atsumu is a dirty thief. Or that he’s wearing his teammate’s sweaty practice clothes.

Subtly, he pulls his jacket up to his nose so he can breathe in Sakusa’s scent. Atsumu feels a tingling sensation run through his body, and he shudders. Both he and his inner omega agree that this is the best scent that could possibly exist. What he wouldn’t give to have his bed full of it. Or the alpha it belongs to.

Then he feels it—this gross wetness soaking his pants. Oh fuck.

Quickly, Atsumu gathers his bag and tries to walk out, but Sakusa catches his arm. “Miya, are you sure you’re okay?”

Oh no. Anyone but him. He feels a throbbing sensation and more slick release. Atsumu watches as Sakusa’s pupils blow and his nostrils flare. Oh fuck.

“Haha, yep. I’m good, thanks. Gotta go!” He runs all the way back to his apartment.

Fuck, that was mortifying. Sakusa definitely smelled him getting wet. This is the first time it’s happened, and of course, it just had to be around Sakusa. Fuck his fucking hormones today!

However, as he strips off his pants to change and clean himself, he’s intrigued. He’s talked to Hinata about it a few times, but he’s never actually done anything with his vagina. Mainly because, well, it wasn’t really working properly. But now provides an opportune moment.

Wearing nothing but Sakusa’s shirt, he grabs a towel and places it on his bed before settling on it himself. He’s not about to get this shit everywhere. He spreads his legs to see a bit of slick on his inner thighs. His dick is still soft. Weird. He doesn’t know how this works.

Hesitantly, he reaches down and feels the wetness with his fingers. Atsumu feels nervous with his hands trembling slightly, but other people do this and it feels good, right? So he gathers more of the slick on his middle finger and tentatively pushes it inside.

It feels strange, not unpleasant or anything though. It’s warm and soft inside. He pumps in and out a few times and tries adding his index finger. There’s a bit more of a stretch, but it feels good. Wiggling his fingers around experimentally, he hits a certain spot and clenches with a groan. What was that?

He presses around again until he finds it. It’s located pretty shallowly, so is that where the internal clitoris is? So that means if he moves up along this wall then… His hips twitch when he hits his prostate. Oh fuck. Hinata was right. He has been missing out.

As he pumps in and out, his cock comes to life. Gathering some slick on his other hand, he strokes his dick in time as he fingers himself. Oh god. An alpha’s cock would hit his clit every time. Oh fuck. Alphas are supposedly really big. Would it fit?

Moaning he thinks about Sakusa. What would it be like to be with him? Would he whisper in Atsumu’s ear? Tell him how good he feels and that he’s a beautiful omega? Call him Atsumu in that sinfully attractive voice? He orgasms from his vagina once before he orgasms again and actually ejaculates.

Whoa. That was crazy weird. A good crazy weird. He needs to buy a dildo stat.

On the last day of practice before their holiday break, the team decides to change it up and go to a club instead of an izakaya. Bokuto insists they go to OWL Osaka. Atsumu suspects it’s purely based on the name. Everyone agrees to meet in front of the club at eight. Even Sakusa says he’ll go. Atsumu raises an eyebrow at that but is silently pleased.

Hinata and Atsumu walk back to the complex together. He wants to help Atsumu get ready, and really, who is he to say no? So Hinata scurries off to his own apartment to change before he comes over to help him.

Hinata arrives at Atsumu’s door dressed in a sequined champagne-colored crop top with fringe on the bottom that covers his exposed midsection. Only when he moves does it allow for a glimpse of skin. His pants are mint green skinny jeans frayed at the ankle. He looks good, pretty. And the light makeup really accentuates his big doe-like eyes.

Atsumu wishes he could wear something like that, but he’s learned from experience that it won’t work out. Hinata is petite and cute like an omega should be. Maybe then he’d actually catch Sakusa’s attention.

“Alright! Let’s see what you’ve got!” Hinata marches into Atsumu’s bedroom to inspect his closet. His face scrunches as he shuffles through the clothes. “Do you not have any omega clothes?”

“Uh… No. They don’t really fit me right.”

Hinata frowns. “Where have you been looking? If I can find things that fit Tsukishima, I can find something that fits you.”

“I dunno, Shouyou-kun.”

“Don’t you want to show off for Omi-san?” Atsumu bites his lip and nods. Hinata beams at him. “Alright then, let’s get a move on!”

Hinata manages to haul Atsumu to an omega clothing store a couple of blocks away. While he scavenges for something in the store, Atsumu is drawn to the display case featuring several collars. He’s not ever really given them much thought until recently. In the last few months, he’s been learning a lot about his dynamic and its history.

Collars can mean a few different things. In the olden days, they were a sign of possession and oppression and typically made of hard leather. Some people still hate the concept of collars because of this. They’re also often used in traditional families for modesty. However, in modern times, they’re mainly seen as a fashion accessory. There are plenty of omegas that wear them daily and have several different types.

Since omegas now have the right to choose whether or not to wear a collar, they are mainly bought by an omega themselves. However, if an alpha gives their omega a collar, it’s a significant exchange. Obviously not every couple indulges in this, but it’s not uncommon.

Hinata wonders over and looks into the case. “Oh! I like that one!” He points to a black velvet collar with a gold sun pendant. “Which one were you looking at?”

“That one.” He gestures to a black leather collar with an opal in the center.

It’s beautiful, but he doesn’t want to buy it. No, he wants an alpha to present it to him. Not just any alpha though, he wants Sakusa Kiyoomi to look at this collar and think of him. And that’s why he buys it—because he thinks Atsumu would look good in it. That his omega would proudly wear a collar from him.

“Atsumu-san?” Hinata regains his attention and holds up what he found. “Want to try this on?”

“Sure.”

He goes into the dressing room and takes a deep breath. Here goes nothing. Atsumu puts on the black slim-fit dress shirt with transparent sleeves and black skinny jeans that Hinata gave him. It fits, so far. Atsumu turns to look in the mirror, and it actually looks… good. It hugs his newfound curves, and the transparent sleeves give it just enough of a sexy vibe.

When he walks out, Hinata stands up from his chair. “Atsumu-san! Yes! That shirt makes your waist snatch! Turn around!” He does and the other omega gasps. “And your ass looks great!”

Blushing slightly he asks, “Ya think so?”

“Yes! It just needs one more thing.” He dashes off only to return with a black belt with a silver buckle. “This will complete the look.”

He ends up buying the outfit. They only have an hour before they’re supposed to meet everyone, so they hurry back to get Atsumu ready.

Hinata was right once again. The belt does complete the look. After applying some eyeliner, he’s ready for the night. Atsumu admires himself in the mirror. Honestly, he looks fucking hot. This is the best he’s felt in a long time.

“Thank ya, Shouyou-kun,” he says, smiling. Hinata grins back at him.

They cut it close, but the two of them arrive on time. The rest of the team is there waiting on them. That includes Sakusa. Atsumu almost chokes when he sees him. Holy fuck he looks hot. No one has a right to look that good. He’s also sporting black on black, but he has the first three buttons undone and the sleeves rolled up on his forearms. Of course, he also has a black mask. Fuck.

He feels Hinata elbow him as they approach the group. “Keep it together, Atsumu-san.”

Oh shit. His scent. He reigns it in just in time. Sakusa is openly staring at him. Swallowing thickly, he greets everyone, “Hey guys! Hope ya weren’t waitin’ too long.”

Bokuto perks up. “Nope! We just got here a few minutes ago. You look really good, Tsum-Tsum!”

Atsumu thanks him as they enter and pay the entrance fee. Since it’s still what’s considered early for nightlife in Osaka, they’re able to grab a table on the first floor. Sakusa slides into the half-circle booth and plants himself in the very center against the wall. Atsumu suspects that’s where he’ll stay the entire night. It’s a wonder why he even came. He hates crowded places like this. Hinata immediately drags him out to the dance floor. Bokuto and Inunaki follow them.

Now Atsumu isn't much of a dancer, but he can move. Hinata, though, shakes his hips like he was born to. It has to be something he learned in Brazil. Atsumu can already tell that several alphas are keeping tabs on him. Good thing Kageyama left his mark.

Bokuto thrives in this environment, and Atsumu can’t help but laugh when he sweeps him into a dance. Thomas, Barnes, and Meian soon join their little group. Atsumu can sometimes see Sakusa sitting at their table through the crowd. His head is pointed in their direction.

Several songs later, he makes his way to the bar. As he’s waiting for his drink, someone sidles up next to him a bit too close for comfort. Turning, there’s an alpha with brown hair and hazel eyes eyeing him. Atsumu subtly shifts a bit further away. The man is actually pretty attractive, but his tastes just happen to lie with those who have two moles above their right eye.

“Hey. Can I buy you a drink?” he asks.

“Thanks, but I just ordered one,” Atsumu says pleasantly. Is he being hit on again? Don’t alphas have any better first lines? Though he’s still flattered at the attention. It feels so different to be approached by an alpha with intent and with the way this guy is looking at him, he definitely has intent.

“Are you here alone?”

The bartender sets his Peach Fizz in front of him as he answers, “Nah, I’m here with some friends.”

“Oh? Well, I’m Yamato Kouta”

“Miya Atsumu.”

He converses with Yamato as he finishes his drink, to which the man buys him another. The alpha is definitely interested in him. It’s hard not to get pulled in with his head a little woozy. Maybe he shouldn’t have drunk those so fast and on an empty stomach. So when Yamato asks him to dance, he accepts.

On the dance floor, the alpha’s hands are latched onto his hips, and his back is against Yamato’s chest. Atsumu has never been in his position before. In the past, he was always the one holding onto another’s hips. He likes it. Except the alpha behind him isn’t the one he wants.

His eyes involuntarily dart over to the table to find Sakusa burning holes where he stands. Atsumu holds eye contact as he brings up a hand to sensually rub across his body as he rolls his hips. Sakusa doesn’t look away, so Atsumu continues his performance. Having Sakusa’s eyes on him like this makes his body flush in excitement. Atsumu wants him to watch.

Something flashes in Sakusa’s eyes as Yamato leans in to whisper in his ear, “Atsumu, you’re so sexy.” But Atsumu isn’t paying attention to him. His half-lidded eyes are solely on the alpha sitting alone at their table. When the grip on his hips tightens, he looks away from Sakusa. “Come home with me.”

The blood rushes in his ears as the loud music reverberates through his body. His head is fuzzy. The flashing lights on the dance floor disorient him. Was the room always spinning? Was this actually happening?

“I can’t. My friends will worry.” He makes an excuse, though it’s partly true. When Atsumu tries to break free of the man’s hold he can’t.

“I’m sure you can just text them. They’ll understand.” His heart rate picks up. Atsumu knows alphas are strong. He’s been pinned by his twin brother on numerous occasions. But never has he been in a real situation like this.

“I don’t wanna. Now lemme go.”

“You’re being such a tease. Don’t make me beg.” Yamato’s voice sounds far from begging. It’s more commanding than anything.

Atsumu squirms and tries to push the alpha away, but he’s at a disadvantage from this position. His head whips over to the table to try and signal someone only to find it empty. Oh fuck. Shit.

“Let go of me!” Even elbowing the alpha seems to have no effect. He can’t get a good angle.

No, no, no. Bokuto said to be careful! He didn’t think this would happen to him. Is the alcohol making him weak? Then he sees a familiar figure stalking towards them.

“Kiyoomi!” he yells and reaches out for the man in panic. Sakusa’s eyes widen, and his pace increases.

“Hey! Get your hands off of him!” Sakusa snarls in a dark tone as he grabs Yamato’s arm. Atsumu manages to weasel his way out of the other’s grasp with the distraction. Sakusa's teeth are probably bared under his mask, and he looks ready to attack if Yamato makes a move.

Yamato turns to face him. “This little slut yours? He was agreeing to go home with me. Maybe you should keep your ome—” he doesn’t get to finish as Sakusa decks him right in the face. He drops to the floor like a sack of potatoes and holds his nose in pain. None of the other clubbers seem to notice or just don’t care, and all Atsumu can think about is how hot that was.

Sakusa grabs Atsumu’s arm and pulls him to the side of the room where it’s less crowded. The alpha is breathing heavily in fury in between growls. Atsumu is sure if this place wasn’t crawling with heady scents, he'd be able to smell the pheromones of pure hostility coming off of Sakusa. Atsumu has never seen him like this. Sakusa pulls his mask down and faces Atsumu to gently hold him by his arms and look him over.

“Atsumu, are you okay? Did he do anything to you?” The genuine fear and worry in his eyes is startling.

Trying to calm him, Atsumu slowly reaches for Sakusa’s face and releases calming pheromones. Sakusa leans into his touch.

“’M fine, Omi. I was just a little scared.” He smiles gently up at him.

Sakusa then pulls him into a crushing embrace and buries his face in Atsumu’s neck.

“I couldn’t stand him touching you any longer. Then when you called out for me like that, I was terrified.” Atsumu can feel Sakusa’s lips brushing against his neck as he speaks. It sends a small shiver down his spine.

Atsumu pulls back and takes Sakusa’s hand to examine it, making sure he’s not injured. When he’s assured there’s no damage, he looks up. Sakusa is looking at him with a tenderness he’s never seen before. He looks… Atsumu isn’t sure.

Still holding Sakusa’s hand in his own, he asks, “Dance with me, Omi?”

He nods and keeps a firm hold of Atsumu’s hand as they make their way back to the dance floor. Sakusa pulls Atsumu’s back flush against his chest with an arm wrapped around his waist. His other hand settles on Atsumu’s hip. He leans into Sakusa, tilting his neck to the side. Sakusa rubs his own neck against him at the invitation, and Atsumu sighs in contentment.

He feels safe, even in the middle of this crowded club. He’s here with Sakusa, swaying with him on the dance floor. Atsumu lays a hand on top of Sakusa’s and his other reaches back to hold the back of his neck.

“Atsumu,” he murmurs, breathily.

Atsumu’s body tingles as that voice caresses him like velvet. His breath hitches when he feels warm breath tickle the shell of his ear. And when Sakusa turns him around to face him, he sees nothing but affection in those dark eyes. He pulls Atsumu close and cups his face with one hand. Atsumu’s hands rest on his chest.

“Atsumu,” he says again, stroking Atsumu’s cheek with his thumb.

Atsumu feels something simmering in his abdomen rise to his chest, his skin hot where Sakusa touches him. “Omi.”

His head is tilted up slightly as Sakusa inches closer, his scent like a hypnotic spell. Atsumu’s heart pounds in his chest—he’s dreamed of this moment. When warm lips meet his own, the world around them washes away like the tide ebbing. The taste of him unfurls Atsumu’s senses with nothing but him as their lips move in a gentle rhythm.

Sakusa then claims his mouth with hunger and desperation, as if he’s been waiting for this moment. Atsumu’s hands have wrapped around Sakusa’s neck without him even realizing it and a hand sinks into his thick, curly hair. Atsumu follows Sakusa’s lead as his tongue conquers his mouth, consuming, pulling him into the warmth of his embrace.

Kissing Sakusa Kiyoomi is nothing like he’s ever experienced before. It’s a groundbreaking sort of momentous moment. It’s a shock to the senses—a revelation of just how intoxicating his presence is, where it becomes a craving, and keeps Atsumu coming back for more. It’s vindication. Vindication that this man wants Atsumu—that he chose Atsumu.

As they pull apart and rest their foreheads together, time seems to resume. But all Atsumu sees is Kiyoomi.

Chapter Text

Atsumu wakes with a smile on his face. Last night was… wow. He touches his lips with his fingers, remembering. Kiyoomi kissed him! And it was everything. The closeness, the heat, the smell… Atsumu doesn’t think he’ll ever forget it. Kiyoomi walked Atsumu to his door and kissed him goodnight after inviting him over for dinner tonight so they could talk about this. Is it hoping too much for Kiyoomi to officially court him?

His inner omega is extremely pleased. It’s preening right now and rolling around in flowers. Atsumu is much the same though as he hugs his stuffed fox that he’s lovingly named Kimi (don’t look into it. It’s a random name, he swears) to his chest.

Is it really happening? Is an alpha—Sakusa Kiyoomi—really interested in pursuing him? He wiggles in his bed in excitement. Tonight will hopefully have all the answers. He can’t wait to tell Suna when he sees him today. Atsumu is practically bursting, having to keep it all to himself.

Getting up to start the day, Atsumu realizes how messy his room is. He doesn’t recall how it got this way nor how he has accumulated several shirts of varying sizes belonging to his teammates. And is that Osamu’s sweater? Scratching his head, he also notices a variety of protein bars and a case of water bottles. What the fuck?

There’s no recollection in his brain. He should probably clean up, but there’s no desire to. He wants it like this. He’s not usually a slob, but he’s content with the arrangement. Weird.

Now that he’s up, Atsumu almost feels a little sick. His stomach makes an unpleasant gurgling sound and cramps when he stretches. He didn’t even drink that much last night. Guess he’ll just have to power through. Hopefully, it’ll go away soon.

Atsumu meets Suna at the underground mall in Umeda. They both have time to kill until their respective dates tonight, so Christmas shopping it is. Yeah, it’s a western holiday, but it’s kind of fun. Suna is actually pretty into it, though he’ll deny it until his dying breath. Atsumu likes all the fun decorations. The lights are so beautiful, especially when it snows. It’s like a scene from a movie.

“So Sakusa Kiyoomi,” Suna says, placing a reindeer antlers headband on Atsumu’s head.

“Yeah,” Atsumu replies with a soft sigh.

“I’m glad he sucker-punched that asshole. Makes him alright in my book.” Suna flicks one of the bells hanging from the antlers.

“Sunarin, it was so hot. Ya don’t understand.”

“And I don’t care to. Have you told Osamu yet?”

“Nah. Didn’t get home ‘til late last night. Ya know how much of a grandpa he is. I’ll tell him once I know there’s somethin’ to tell.” He removes the antlers, looking at them fondly before putting them back on the shelf.

They continue browsing, and Atsumu wonders if he should get something for Kiyoomi too. It’s not like they’re anything official. Yet. He hopes tonight will clear things up. Kiyoomi had wanted to talk about everything after sleeping to make sure they were both clear-headed, which is understandable. Atsumu had been slightly intoxicated last night.

Would anything more have happened if that hadn’t been the case? Did… Atsumu want something more to happen?

“I get that you want him to rail you, but can you tone it down a bit? We’re in public,” Suna says, not even looking at Atsumu.

Atsumu blushes furiously. He hadn’t really been thinking about that. Now it’s in his mind though. But then, Atsumu thinks about what else Suna said and furrows his brows. Tone what down? He’s not releasing any extra pheromones. Maybe he is unconsciously? His stomach still hurts, and he feels a little warm. Hopefully, he’s not actually coming down with something. He wouldn’t want to accidentally infect Kiyoomi.

Suna turns, looking at him with those analyzing eyes. “Atsumu, are you in preheat?”

Oh. That would make sense. Thinking back, his behavior over the last week could definitely be explained by that. The eating more, the sensitivity to pheromones, the nesting. He cringes. Is that what the disaster in his room is? That’s embarrassing. He needs to fix it immediately.

Then realization really hits him. Oh. Now the panic sets in. He’s not prepared. Dr. Yoshiba even told him it might start early, and what did he do? A big fat nothing. Atsumu thought he had more time.

“Whoa, whoa, calm down. It’s fine. You’re fine.” Suna offers Atsumu his wrist. He grabs it, rubbing his own wrists against it to scent himself. “Let’s just start heading back to your place.”

Atsumu nods, keeping hold of Suna’s arm. The anxiety is making it worse. He’s hyper-aware of his labored breathing and the clamminess of his skin. People are looking at him.

“Rin, I’m scared,” he whispers and snuggles closer to Suna.

“It’ll be fine. I just started noticing the change of scent, so we have time.” He adjusts himself to wrap an arm around Atsumu’s shoulders, and Atsumu clings to his waist.

Suna walks as fast as Atsumu lets him, but it’s difficult. His lungs need more air; it’s like he’s not getting enough.

Dr. Yoshiba said this is going to be bad. Exactly how bad is bad? She didn’t seem very optimistic about it being mild. Atsumu is twenty-three. That’s old for never having a heat before. What’s going to happen?

The feeling in his stomach sinks its claws into him, climbing up, spreading over his body. Atsumu’s breath hitches, his frame trembling.

“Rin,” he says coming to a stop and hunches over.

“Atsumu?”

Suna catches him before he falls on the ground as his legs give out. Atsumu wails out, feeling as though he’s been shocked.

“Oh fuck! Atsumu, just hang on. Fuck!” He kneels them down, right there in the middle of the store.

It burns where Suna touches. The bright lights sting his eyes through his hazy vision. It hurts. Oh god, it hurts. Cut it out of him! Atsumu doesn’t know what it is, but get it out! He clings to Suna, shoving his face in the crook of his neck.

“Yes, I need a car. My friend just went into heat unexpectedly.” Suna must be making a phone call. “Whity Umeda. Thank you.” He picks Atsumu up, who is still crying into Suna’s shoulder. “I called Omega Services. They’re on their way. I’ve got you, it’ll be fine.”

Atsumu wraps his arms around Suna’s neck and tries to inhale more of the calming scent. Gasping for air, Atsumu isn’t at all certain that it’ll be fine.

Suna maneuvers Atsumu into the backseat of the car and slides in after him.

“Why does he smell like that? They told me he’s in heat,” their driver says.

“He is, it’s a medical condition. Now drive!” Suna pulls Atsumu to him again to comfort him. Then he’s on the phone again. “Come on, Osamu, pick up! This is not the time to— fuck!”

Sweat runs down his face and his cheeks are flushed, but there’s no desire to do anything other than curl in on himself. He’s too weak, and every move that jostles him sends blinding pain through his body. Is this really what heats are like? He thought there was supposed to be lust consuming him. Where’s that?

“Osamu! Thank fuck. Atsumu’s heat started. No, we’re on our way there now. Okay.” Suna strokes Atsumu’s hair, brushing his bangs off his sweaty forehead. “Osamu is meeting us at your apartment, okay?”

Atsumu whimpers. Suna and Osamu will take care of him. He’ll be okay, right?

As soon as the car comes to a stop, Osamu opens the door. “‘Tsumu, hey yer almost back, ‘kay?”

“‘Saumu,” he whines. “Hurts.”

“I know.”

Osamu takes over the task of carrying Atsumu up to his apartment. His twin’s pheromones help a little more in comforting him. However, it’s not near enough to ease the pain.

He’s set down on his bed—his nest—and grabs Kimi before curling into a ball. Hot, thick tears roll down his cheeks as he looks up at Osamu through his glassy eyes.

“Can I come in?” Osamu asks. Atsumu nods.

“What about me?” He nods again.

Both Osamu and Suna get into his nest and snuggle close to him, scenting him, comforting him. Is this how this is going to go? How long is this going to last?

A wave of stabbing pain ripples through him, causing another scream to ring in the air. He recovers, gasping. Suna rubs circles on his back while Osamu presses Atsumu’s head to his scent gland. They’ll protect him.

But what about Kiyoomi? He whines, and his inner omega reaches for a presence that isn’t there. His alpha?

Kiyoomi paces back and forth in his kitchen. He’s already double and triple-checked everything, but he still feels like he’s forgetting something. It’s probably just nerves. Kiyoomi doesn’t get nervous. Anxious, yes, but nervous? It’s been years. Of course, the reason for this can only be Miya Atsumu.

Miya Atsumu who after tonight will finally, finally be his omega. If he says yes. Kiyoomi adjusts the box on the counter again. He’ll say yes.

He’s acting ridiculous. Only Miya Atsumu can throw him this off-kilter. It’s always been like this, but it wasn’t until he joined the Black Jackals that it became a problem. Everything about Atsumu left him confused, especially when his inner alpha was interested.

When Kiyoomi was younger, he had problems always being rational when angered. It’s like his alpha completely takes over and sees red. Provoking him into anger wasn’t all that difficult either. Since taking his medication and getting older, it’s much more manageable, but he almost lost it last night. If Atsumu hadn’t been there, who knows what he may have done.

And that’s the thing—he’s never been angered like that over an omega. Yes, he tried to date a few girls in college, but there’s a big difference between dating and courting. Courting is monogamous, serious with intentions of a potential mate. When the girls he dated expressed their want to be courted, Kiyoomi broke it off. They just didn’t appeal to him. Not like Atsumu.

Atsumu, who draws him in like a siren. Atsumu, who has stars in his eyes. Atsumu, who smells like heaven. Atsumu, who sounds like a dream.

It was confusing—feeling this pull to him. He was an alpha. Kiyoomi isn’t into alphas. So why, why did his alpha feel restless when Atsumu was near? It pissed him the fuck off. Taking his frustration out on Atsumu wasn’t the best option, and he was called out on it.

When he gave in and decided to befriend Atsumu, it only got worse.

Miya Atsumu is a good person. A great person. The things he does for those he cares about surprised Kiyoomi at first, but not once he got to know him. He’s considerate, charming, caring… All traits he never would have associated with him years prior. The fact that Kiyoomi liked Miya Atsumu was a bizarre concept.

With that came the irrational jealousy, possessiveness, want… Kiyoomi thought he was going mad. Every time he smelled a foreign scent on Atsumu, he felt his hackles raise. One time it was his brother for god’s sake!

Kiyoomi was trying to accept that he might be gay when Atsumu flipped his world on its axis again—when he came out as an omega. He couldn’t quite process it at first. Because Atsumu? An omega? Could Kiyoomi dare to hope? Then when he explained about his medical condition everything fell into place. Kiyoomi was in shock and had a lot to think about—things to plan.

When Atsumu got his omegan scent, it was all over, not that it wasn’t before, but Kiyoomi knew that there was no one else he wanted. The past month has been excruciating. Kiyoomi had been trying to gather up enough confidence and make sure everything was in place before he asked Atsumu if he could court him. And watching the changes Atsumu has gone through was a test of his sanity because fuck.

He’s not privy to how hormone therapy really works, but it’s sure working well. If he thought Atsumu had a nice ass before, it’s fucking exquisite now. Kiyoomi wants to run his hands all over that tight body, wrap his hands around that tiny waist…

Kiyoomi got his first taste last night, and he’s addicted. Atsumu smells like jasmine and tastes like honey. He wants more. He wants to smell and taste him where there aren’t other people, where it’s just them and he can indulge in the sweetness that is purely Atsumu.

Of course, that’s not the only reason he wants Atsumu as his omega. It’s a nice bonus though.

He realizes now that he’d essentially been trying to court Atsumu without even asking, and that’s embarrassing. However, he’s ready now. He’s had this courting gift longer than he’d frankly like to admit. And if Atsumu will let him, he’ll gladly put a claiming mark on him to keep those other damn alphas away.

It’s no surprise that Atsumu would attract alphas—he’s gorgeous. But if Kiyoomi ever has to witness some disgusting cockroach put their grimy hands on his omega again, he might do something he’ll regret. Seeing Atsumu dance with that bastard last night truly tested him. And the little shit had the audacity to tease him. Kiyoomi smiles and shakes his head thinking about it. Atsumu sure is something.

Glancing at the clock, he furrows his brows. Atsumu should be here by now. He’s never late. Kiyoomi checks his phone to see if he has a message. None. Is… Is he being stood up? He’ll wait a little longer before he does anything… rash.

When his phone dings with a notification, he almost drops it in his haste. He frowns when it’s Motoya.

Motoya
Kiyo have you seen this?
[VIDEO ATT]
It might be nothing so don’t be stupid.

Scrunching his nose in distaste, he taps on the link. It’s a shoddy video taken from a cell phone, but on the screen, he identifies Suna Rintarou and Atsumu. He can’t really hear anything being said over the noise in the video, but Atsumu is clinging to Suna as they kneel on the floor. Suna’s on the phone. Then he picks Atsumu up and runs off.

What the fuck?

He scrolls to the comments to see if he can get any insight, which is a mistake. They only serve to piss him off.

Are they dating?
I heard he collapsed.
Did Suna hurt him?
Oh no! Poor Atsumu-san!
I saw them being all over each other in Umeda.
I heard he was screaming…

Squeezing his phone, Kiyoomi tries to calm down. He can feel himself getting worked up, and before he knows it, he’s already out the door and heading down the stairs to Atsumu’s floor.

He knows Atsumu and Suna are friends. Atsumu talks about him a lot and hangs out with him often. And was apparently all over him today. If this beta bastard thinks he’s going to steal Atsumu from right under his nose, he’s got another thing coming. He’s seething by the time he reaches the right floor.

However, he’s suddenly hit with a putrid scent. It’s sour and rotten, but there’s no denying that it’s Atsumu. Kiyoomi dashes down the hall and knocks frantically on Atsumu’s door after finding it locked.

When an ear-piercing wail breaches the air, he starts banging. “Atsumu!”

“Sakusa, you need to calm down,” comes a voice from the other side. He’s pretty sure it’s Suna.

“What the fuck did you do to him?! Let me in!”

“I didn’t do anything. Now, if you’d calm the fuck down, I will.” The deadpan voice irritates him further.

“Why does he smell so distressed then?! I will fucking knock this goddamn door down!”

Suna finally raises his voice. “He’s in fucking heat!” Kiyoomi freezes. Heat? But he smells… “He’s in terrible pain because of his gland disorder. It’s his first heat.”

Kiyoomi swallows thickly. “Ever?”

“Ever.”

Kiyoomi doesn’t know a lot about heats, but he does know that the older a person is when they have their first one, the more debilitating it is. And a person in their twenties having one for the first time? Unthinkable. And who knows how much pseudoalphaism adds into that equation as well.

Suna lets him in when he’s calmed down and leads him to where Atsumu and Osamu are. Atsumu lays curled against his brother’s side, and Kiyoomi wants to immediately go to him, but he knows better.

“Why’d ya let him in here, Rin?” Osamu glares at Kiyoomi.

Suna sighs heavily. “I’ll tell you in a minute.”

Atsumu slowly lifts his head. His eyes are bloodshot and dried tear tracks cover his face. Kiyoomi’s need to comfort him sits on a thin thread.

“Omi?” Atsumu says in a near whisper and reaches out a hand towards him.

“I’m here, Atsumu.” He glances at both Suna and Osamu before crawling into Atsumu’s nest. His heartbeat thumps against his chest at being let in. He’s never been in an omega’s nest before, never had the desire to even want to be. Not until now.

When he’s settled in, Atsumu shifts over to cuddle against him instead. Osamu’s glare hardens at Atsumu choosing him. However, Kiyoomi is only concerned with the man in his arms.

“Ya better keep yer dick in yer pants, Sakusa. I swear I’ll rip it off if ya even think ‘bout touchin’ him,” Osamu says once he’s standing next to Suna.

“You have my word.”

Osamu nods in satisfaction. “Good. We’ll be out here. Gonna make food.”

He’s left alone with a trembling Atsumu. He lays them both down and holds Atsumu close, letting his face press into his scent gland. Kiyoomi can honestly say this is not how he expected to spend a heat with Atsumu for the first time. Not that he’s thought about that… often…

Examining the nest, he spots a few of his missing shirts and smiles, glad that Atsumu wanted them. He also sees the fox he gave him wrapped in Atsumu’s arms. Cute.

Kiyoomi feels Atsumu’s body tense as he whimpers and lets out another heartbreaking cry. He feels so useless. His calming pheromones are only doing so much. Never has he heard of a heat like this before. There's a very minimal scent of arousal, and he’s pretty sure that’s only from the slick being produced. Atsumu himself is only letting out distressed and pained pheromones.

Osamu and Suna come in to bring pain medication, food, water, and sometimes one or both will lay with Atsumu as well. No one knows how long this is going to last. Osamu called Atsumu’s doctor and she gave an estimate of up to a week. It’s not promising.

Atsumu doesn’t do much of anything for four entire days, and it’s excruciating for Kiyoomi to watch. Any time he’s given food, he can’t keep it down. He passes out from sheer exhaustion more than once, and his cries twist Kiyoomi’s heart.

If there’s anything Kiyoomi can do to help take away Atsumu’s pain, he’d do it. The three of them are doing what they can. The only other solution for heats is sex, but that’s not going to happen. In this situation, would sex even help at all?

On day number five, Atsumu seems a bit more lively. His sour scent is less thick in the air, and he shuffles around in the nest. His face is still flushed, and his breathing is labored.

“Omi?” Atsumu tugs on Kiyoomi’s shirt.

“Yes?”

“Ya stayed.”

“Of course I did.” He cups Atsumu’s check and wipes away a stray tear with his thumb.

“Omi-Omi,” Atsumu says breathily. He inches forward to nuzzle his face into the crook of Kiyoomi’s neck once again. However, at the sudden wet sensation on his gland, Kiyoomi’s eyes widen, and he suppresses a groan.

Atsumu pulls back, looking at him with pleading eyes. “Sorry, Omi. Ya just smell so good.”

Kiyoomi’s eyes linger on Atsumu’s slightly parted red lips. Leaning in he says, “It’s okay, Atsumu.”

He captures Atsumu’s mouth, tasting that sweetness that he craves. Bringing a hand up, he holds the back of Atsumu’s head. Hands clutch at the front of Kiyoomi’s shirt as Atsumu leans into him. A small whimper escapes his mouth that Kiyoomi greedily wants to hear more of. He doesn’t let the kiss get too heated, though god, he wants to.

If he could, he’d draw every beautiful sound out of Atsumu possible. He’d worship every inch of his skin, pull pleasure from his deepest core. Kiyoomi wants to indulge in every part of Atsumu, wants him closer, closer.

When Atsumu moans into his mouth, Kiyoomi has to break the kiss. Keeping a semblance of control, he pulls Atsumu to him, though there’s a discontent grumble, and plants a kiss on the top of his head. He won’t take this further just yet. He still needs to properly ask Atsumu to be his. And he did promise Osamu… For now, he’s content with Atsumu feeling better and holding him in his arms.

The next day, Kiyoomi wakes to Atsumu flopped over his chest, drooling all over his shirt. It’s disgusting, but he smiles anyway. Stroking Atsumu’s hair, he notices that the horrible scent is gone, and Atsumu once again smells of jasmine, though it’s faint.

Atsumu’s lids slowly blink open, and Kiyoomi is met with those stunning golden eyes he’s so fond of. Kiyoomi could wake up to this sight every day. What better way to start the day than with a face as beautiful as Miya Atsumu’s?

“Mornin’, Omi.” His groggy, sleep-laced voice mumbles.

“Good morning.” Kiyoomi continues stroking the blonde locks, letting Atsumu nuzzle into his touch. Smiling, he knows he could get used to this.

Atsumu’s heat is over now, but Kiyoomi doesn’t leave. How can he when his omega is weak and exhausted? Though Osamu does not let Kiyoomi help Atsumu bathe, and sends him a dirty look when he offers. Suna seems vaguely amused at the display. He only meant it as help, honest.

Kiyoomi knows the three of them are good friends, but after spending more time around Suna and Osamu he thinks there might be more going on between them. It’s not his business, though, so he won’t ask. Instead, he makes himself busy by preparing breakfast.

Atsumu enters the kitchen looking much more refreshed. He plops down at the table and flops his arms and head on it. “Omi~” he whines, “our date.”

He chuckles at the dramatic display. “We can reschedule.”

And they do for tomorrow. Osamu kicks him out, much to his own chagrin, after breakfast. He supposes Atsumu needs to rest, and he needs to shower. Badly.

Kiyoomi is once again waiting on Atsumu to arrive. He should be here any minute. This time Kiyoomi isn’t nervous. He has full confidence that his courting offer will be accepted. After Atsumu invited him into his nest and allowed him to stay with him through his duress, it cemented in his mind.

The knock on his door paints a smile on Kiyoomi’s face. Atsumu’s here.

“Omi-kun!” An enthusiastic Atsumu greets him.

Kiyoomi chuckles, letting him in. “How are you feeling?”

“Still a little achy but a lot better.”

Kiyoomi had a plan, but now that Atsumu’s here in front of him, it’s just gone. Fuck the plan. He wants to do this now. Dinner can come after.

“I’m glad.” He takes Atsumu’s hands in his own and leads him to sit on the couch together. Rubbing his thumbs in circles on the soft skin of the back of Atsumu’s hands, he begins, “Atsumu, ever since I joined the Black Jackals, you’ve never failed to entrance me. At first, I didn’t understand why my inner alpha was drawn to you, but now I do. Even before I knew you were an omega, I wanted you. I still do. So Miya Atsumu, will you allow me to court you?”

Atsumu’s eyes shine golden with flecks of brown and green, reflecting his own hopeful face back at him. He bites his lip, trying to contain his smile, but Kiyoomi sees it all. His own heart beats steadily in his chest, and he reaches for the long thin box on the coffee table. Opening the box Kiyoomi presents it to him.

Atsumu gasps. “Omi! Oh my god!” He covers his mouth with a hand, wide-eyed.

Okay, this isn’t a reaction he expected. Did he fuck up? Is his gift bad? He doesn’t know what to do, internal panic mounting.

He slowly pulls back the box. “I can find something else. Something better. I can—”

Atsumu suddenly squishes his face with a hand on either cheek and smiles fondly at him. “Yer crazy, ya know that?”

“Hm?” He doesn’t know what he did.

Atsumu rolls his eyes, shaking his head before releasing his face. “Yes. Of course, I’ll let ya court me, Omi. Ridiculously expensive gift and all.”

Kiyoomi relaxes and smiles. His inner alpha is extremely pleased. “So you like it?”

“Who wouldn’t? Jesus Christ. Put it on me?” he holds his arm out.

Nodding, Kiyoomi takes the bracelet out of the box and clasps it around Atsumu’s left wrist. It’s a black diamond tennis bracelet set prong style in yellow gold. It looks good on him. But Kiyoomi thinks Atsumu would probably make anything look good.

Atsumu sets the empty box back on the coffee table and scoots closer to him. Delicately touching Kiyoomi’s cheek with just the pads of his fingers, Atsumu places a kiss on his jawline.

“Thank ya… Alpha,” he murmurs.

A full-body shudder wracks Kiyoomi’s body. Meeting Atsumu’s hooded eyes, he looks extremely smug. Narrowing his eyes playfully, he pulls Atsumu onto his lap to straddle him. A surprised squeak escapes the omega at the easy manipulation.

Kiyoomi wraps his hands around Atsumu’s waist and revels at how his thumbs almost touch. He pulls him closer until their foreheads rest against each other, and Atsumu braces his forearms on the back of the couch, inching closer until their lips brush.

Kiyoomi licks Atsumu’s bottom lip. “Anything for my omega.”

Chapter Text

Kiyoomi’s mouth muffles Atsumu’s moans as they kiss on the couch. The hands around his waist hold him tightly in place where he’s straddled across Kiyoomi’s lap. Like this, he can finally get a proper taste and smell of Kiyoomi. There’s no room full of undulating bodies or soul-gripping pain holding him back from this sensation. Calming sandalwood rushes through him in waves, soaking into his skin like a balm for any remaining tensions Atsumu has.

What tensions could Atsumu possibly have when he’s kissing Sakusa Kiyoomi, his boyfriend who is courting him. Not even thoughts about the talk he had with Osamu earlier can bring down his high. That had been a trip though.

Atsumu has seen several sides of Osamu, however, the pouting protective brother was new. Suna—the bastard—was eating it all up watching them. He was going to tell Osamu everything, his stupid heat just happened to hit. It wasn’t a walk in the park by any means either.

Dr. Yoshiba hadn’t been overexaggerating at all about the pain. Atsumu is honestly scared shitless for his next one. It won’t be like that again, right? Heats typically happen every three moon cycles, but since his hormones are still regulating, who knows what could happen.

Kiyoomi showing up had been a complete, but pleasant, surprise. Between him, Osamu, and Suna, Atsumu felt well taken care of and safe. Though he does feel bad for throwing off everyone’s holiday schedule. It’s Christmas Eve, and they were supposed to be back in Hyogo, but that kind of fell through. Atsumu is perfectly content being here with Kiyoomi though.

One of Kiyoomi’s hands cups his cheek, angling him to his liking and gently caresses the soft skin. Atsumu runs his fingers through thick curls, pressing closer into the kiss. Their passionate makeout session is interrupted by rapid knocking on the door.

Pulling back, Atsumu sees Kiyoomi’s face pale. “Fuck.”

Atsumu raises an eyebrow at his expression. The knocking continues.

Kiyoomi gently maneuvers him to sit on the couch and says, “I’m so sorry for what’s about to happen.”

He receives no other explanation as he watches Kiyoomi walk to the door and run a hand through his disheveled hair. Atsumu isn’t sure what he’s expecting when the door opens, but a small omega woman crushing Kiyoomi into a hug before pulling back and smacking him repeatedly on the arm isn’t it.

“Sakusa Kiyoomi, you’ve had me worried sick! You were supposed to be home days ago! I couldn’t get a hold of you, and Motoya had no idea where you were either!”

A tall alpha man comes into view after her and sighs. “I tried to stop her, but you know I can’t.”

“What do you have to say for yourself, young man?”

Atsumu peers over the back of the couch, watching this all go down. The woman is stunning, regardless of her most likely being in her late fifties or early sixties. Her ebony hair hangs just above her shoulders, and a single beauty mark sits high on her right cheekbone. The man has thick black hair with white peppered throughout and wears half-rimmed glasses. He’s handsome, and if Kiyoomi looks like that when he’s that old, well, the genes are pretty damn good.

It’s immediately apparent that these are Kiyoomi’s parents. Atsumu can see pieces of him in each of them. So this is what Kiyoomi meant when he apologized. Atsumu is not prepared to meet the parents, but here they are. Looking down he assesses his outfit—a tight-fit off-shoulder, red sweater and white skinny jeans. It’ll do. He casually pulls the sweater up on his shoulder so it’s not exposed anymore.

“I was busy,” Kiyoomi says.

“And what could possibly be so important?”

Atsumu supposes that this is where he should take initiative and introduce himself. He stands up and makes eye contact with Kiyoomi’s father. His eyes soften and crinkle as he places a hand on Mrs. Sakusa’s shoulder.

Both Kiyoomi and his mother turn to him. “Ah, I’d like to introduce—” Kiyoomi starts, but is cut off by his mother’s gasp.

“Miya Atsumu!” she says and is suddenly in front of him. “Oh, you’re even more handsome in person!” She grabs his face with both hands, turning it from side to side.

Atsumu freezes, unsure how to respond to the enthusiastic greeting. Looking over to his boyfriend for help, he only sees Kiyoomi with a mortified expression. “Kiyo has told me so much about you!” Atsumu can feel Kiyoomi’s aura sinking into the ground.

“Has he now?” Atsumu smirks down at the woman still holding his face.

“Dear, why don’t you let the poor boy go and actually introduce yourself,” Mr. Sakusa says. “Sakusa Ryuuji.” He nods his head to Atsumu.

She releases him and smiles. “My name is Sakusa Akira, but please, just call me Akira. I’m so glad to finally meet you!”

“It’s a pleasure to meet ya,” Atsumu says, bowing.

Akira’s eyes glance down, and she grabs Atsumu’s arm, bringing it to eye level. “Oh, Kiyo! You finally asked him! Why didn’t you tell me?”

Kiyoomi sighs and walks over to Atsumu’s side. “Because it literally just happened an hour ago.”

“Then what’s your excuse for worrying me?”

“Atsumu unexpectedly went into heat.”

Akira’s eyes widen. “Oh! Well, in that case, I hope he took good care of you, Atsumu-kun.” She pats his arm and releases him with a sly smile.

Heat rises to Atsumu’s face faster than his brain can completely comprehend what has been implied. Oh god. Kiyoomi just— Now his parents think— Atsumu wants to die. He sputters, but nothing comes out. This is fucking mortifying. He elbows Kiyoomi in the ribs. Hard.

Kiyoomi lets out a small grunt but thankfully gets the hint. “Mother, no, please. I was helping Atsumu’s brother and friend look after him. You know, because of his condition I told you about?”

Atsumu wonders briefly how much Kiyoomi has spoken to his mother about him. He picked up on the fondness he has for his mother early in their friendship, but he didn’t realize they were so close. It’s extremely endearing.

“Oh.” Akira frowns and rubs Atsumu’s shoulder soothingly. “I do hope you’re feeling better then.”

“Uh, I am. Thank ya.”

Akira smiles at him with all the warmth he imagines only a mother can. “So, Atsumu-kun, what are your plans for the holidays?”

“Oh, uh, probably nothin’ really. My Pa is still in Hong Kong for work,” he says. Kiyoomi’s eyes widen in a slight panic. Did Atsumu say something wrong?

So that’s how he finds himself where he is now—standing in front of Kiyoomi’s childhood home. When he called Osamu to freak out about being invited to Kiyoomi’s family get-together, he only laughed. Atsumu hung up on him, still hearing the ringing laughter through the speaker. Apparently, Sakusa Akira will use any excuse to get all her kids together, so Christmas is a tradition in their household.

It’s late when they arrive, so the few strands of lights on display light up the night. On the train ride here, Kiyoomi had apologized profusely, but Atsumu doesn’t really mind. Akira is bright and bubbly, and seeing the small smiles quirk on both Ryuuji and Kiyoomi’s lips brings a smile to his own face.

He knows Kiyoomi has an older brother and sister. Beyond that, he doesn’t know much else though. However, he’s fed so much information on the ride over, it makes his head spin.

“Masashi’s the oldest, he’s bonded and has two kids.”

“I didn’t know ya were an uncle, Omi-kun!”

“Then there’s Asami, and she’s the definition of a beta bitch. She’s married and has a five-year-old daughter. Don’t tell anyone, but she’s my favorite.”

“Omi! Yer so cute!”

“Shut up!”

Atsumu is a bit intimidated. He knows Kiyoomi’s family is wealthy—he got him a fucking black diamond bracelet for crying out loud! But the home that sits in front of him is a far cry from the one he grew up in.

Kiyoomi takes Atsumu’s bag and places a hand on the small of his back. It’ll be fine. He’ll just be meeting all of his boyfriend’s family tomorrow. The day after they officially got together. No biggie.

He’s led to Kiyoomi’s old room. It’s pretty bare since he has most of his belongings in Osaka now, but old volleyball awards have remained. And of course, he has a nice, big, comfy-looking bed. It’s now Atsumu realizes that he’s going to be sleeping in the same bed as him. Even though he technically did during his heat, this is different. Now, he’s fully coherent and not in crippling pain.

Kiyoomi sees him looking at the bed and says, “If it makes you uncomfortable, I can show you to a guest room. I shouldn’t have assumed…”

Atsumu walks over and wraps his arms around Kiyoomi’s waist. “Thanks, but I’m good. I was just thinkin’ that I’ll finally get to enjoy ya holdin’ me.”

Kiyoomi takes Atsumu’s face in his hands, kissing him gently on the lips. “Thank you for putting up with this.”

He smiles, looking into those dark eyes, and here in a well-lit room, free of any distractions—just a breath apart, Atsumu realizes that they’re actually a deep emerald green. Though that’s not all he finds hidden in their depths. Soft, tender adoration floats to the surface where Atsumu can safely wade into its warm presence.

“Yer welcome, Omi. Though I don’t really mind.”

It’s not yet even been a day, but somehow Atsumu just knows—knows that this feels right. Even his inner omega is content, curled up comfortably. Atsumu knows that he still has several trials to overcome in the near future, but with Kiyoomi’s and everyone else’s support, he thinks he’ll be just fine.

When they climb into bed together, Kiyoomi pulls Atsumu against his chest. He buries his face into Kiyoomi’s neck, inhaling his scent. Relaxing into his hold, Atsumu quickly falls into a peaceful slumber.

Christmas is a lively affair. It starts with Kiyoomi’s bedroom door banging open and a small lump pouncing on them.

“Kiyo-oji!” The little lump climbs up further and pauses, spotting the bed’s second occupant. “Oh, who are you? Why are you in Kiyo-oji’s bed?”

Kiyoomi groans and sits up. Their bed invader promptly plops herself in his lap and looks up expectantly. Atsumu sits up and takes in the scene. A little girl with wavy black hair and sparkling obsidian eyes sits in Kiyoomi’s lap, looking as comfortable as can be. It’s adorable.

“This is my boyfriend Atsumu. Atsumu, this is my niece Yumi.”

“Hi there, Yumi-chan! It’s nice to meet ya,” Atsumu says with a smile.

“Oh!” Her eyes widen, and she bows to him from her little perch. “Hello, Atsumu-ojisan! You smell nice!” Atsumu chuckles and thanks her. She’s so cute.

The thought of having children always terrified Atsumu. At first, it was because he thought that would become his only purpose in life as an omega. Then he suppressed it for so long that it only seemed like some far-off fever dream he once had. When he finally went to the doctor and was told that he may be infertile, it all came back to reality—the panic that no alpha would want him because of this defect.

It’s something he obviously hasn’t ever discussed with anyone, let alone Kiyoomi. Does Atsumu even want kids? He’s never spent much time around tiny humans. The only kid he really knows is Suna’s younger sister, and she’s not much of a kid anymore. God, what is she now, seventeen? Wow. And would Atsumu even be a good parent?

He watches Kiyoomi talk to Yumi with a small smile, and Atsumu’s heart clenches. Does Kiyoomi want kids? Can… Can Atsumu even give that to him? Logically he knows that it’s way too early to be thinking about that, but it’s still an important factor in a courting relationship. Thinking about a small version of Kiyoomi pattering feet around the room, Atsumu thinks, yes, he’d give that to Kiyoomi. But what if he can’t?

Meeting the rest of Kiyoomi’s family goes pretty smoothly. Masashi is friendly and all warm smiles; he’s a complete teddy bear. Asami is a lot like Kiyoomi when Atsumu first met him, reserved and outwardly cold. However, he can see the amusement dancing in her eyes when Kiyoomi pouts as Yumi chooses Atsumu’s lap over his. They’re all stupidly gorgeous and could be models. The Sakusa gene is something else.

Everything is going great until everyone sits down for dinner. It’s Masashi’s eleven-year-old daughter who breaks the comfortable atmosphere.

“Is it true that you’re not a real omega?” The silence is palpable. No one moves a single finger. She looks around with a curious expression. “I was just wondering. Mom’s the one who said it, not me.”

Atsumu looks down at his lap. He can feel Kiyoomi’s presence next to him shift, his body tensing and aura darkening. Not a real omega?

“And what exactly did she say, Saori?” he asks in a restrained tone.

She immediately realizes that what she said is not the innocent question she thought it was. Atsumu digs his fingers into his clothed thighs and bites his lip. Maybe it’s just a misunderstanding.

“Kiyo-oji, I—” she cuts off most likely due to Kiyoomi’s sharp look. “She said that Atsumu-ojisan is an alpha pretending to be an omega.”

“She what?” Kiyoomi’s voice drips with barely contained anger.

Atsumu’s chest tightens, feeling his arms go slack. Do people really think that? He’s vaguely aware of Kiyoomi standing up and several voices fill the air. Is he that much of a freak? A swirl of pheromones clouds the air, and Atsumu needs to get out of here.

There’s silence again when he stands. “Excuse me,” he says, bowing and quickly leaves, shaking Kiyoomi off when he tries to stop him.

Locking himself in the bathroom, he supports himself on the sink, looking at his reflection. His pale face with hollow eyes stares back. A comment like that shouldn’t affect him. Why is it affecting him? He’s stronger than this.

I’m an omega. He tells himself. I’m an omega! Why does it sound like a lie?

Atsumu rubs at his eyes as they begin to sting and his chest heaves. His inner omega feels like it’s been kicked. There’s a pain in his soul of not being good enough. Does he still carry too much of his years pretending to be an alpha with him? Is he not pretty enough? Too outspoken? He’s never even been called pretty…

Splashing cold water on his face helps soothe his puffy skin, but it doesn’t completely remove the evidence of his red-rimmed eyes. Is he a fake since he has to take omega hormones? Is that it? Kiyoomi likes him though, right? He wouldn’t have asked to court him otherwise. Atsumu looks at his left wrist. The bracelet sparkles, catching the light. That’s proof of his intent.

A soft knock on the door tears him from his self-deprecating thoughts. “Atsumu-ojisan?” Comes a small voice. Looking at himself one last time, he opens the door. Yumi stands there with a soft-looking stuffed rabbit with floppy ears. “This is Chou. She makes me feel better when I’m sad.” She holds it up to Atsumu.

Atsumu’s lip wobbles, but he holds it in. Squatting in front of Yumi, he gently takes the rabbit and smiles at her. “Thank ya, Yumi-chan.”

“Hugs help too.” She holds her little arms open and Atsumu gladly accepts it.

They’re giggling together on Kiyoomi’s bed when said man finds them. He silently comes to sit next to Atsumu, tentatively wrapping his arms around him. Atsumu relaxes into his hold.

“Yumi, can I have some time alone with Atsumu?” he asks.

Yumi nods and slides off the bed. “Don’t forget Chou,” Atsumu says. “Ya both made me feel a lot better.” She takes her rabbit and grins widely before skipping out the door.

Kiyoomi pulls Atsumu between his legs and just holds him tight for a long moment. He hums in contentment, nuzzling against his jaw.

“Atsumu, I’m so sorry you had to endure that.”

“It’s alright, Omi. It ain’t yer fault.” He reaches up to stroke Kiyoomi’s cheek with the backs of his fingers.

Catching Atsumu’s hand, he places soft kisses on each knuckle. “Still, it shouldn’t have happened. I never was fond of Masashi’s choice of mate, but I didn’t think she’d do something like this.”

“This ain’t gonna be the last time this happens, ya know. I’m just gonna have to get used to it.”

Kiyoomi squeezes him tight. “You shouldn’t have to. We can leave if you want.”

Atsumu maneuvers himself in Kiyoomi’s hold to face him. “No. I like yer family, Omi. Just stay with me for a bit longer?”

“Of course.” Kiyoomi kisses Atsumu chastely, but Atsumu doesn’t let him get away with just that, pulling him back in.

There’s nothing rushed or desperate about it, just warm languid kisses, taking their time. It’s enough to make Atsumu forget what he was even so worried about.

They stay through the new year’s celebration. Having family together like this is something Atsumu never knew he was missing. Their dad is rarely home for the holidays, so it’s usually spent with just Osamu and him or some friends—usually Suna. But seeing this, he starts to understand Akira’s want for the family to come together.

Atsumu enjoys spending time with everyone. Masashi’s mate doesn't say a single word to him, and he’s completely fine with that. Akira, on the other hand, somehow manages to convince Atsumu to go shopping with her. Kiyoomi only gives him a faux sad smile when he’s practically dragged out the door.

That’s a wild time. Sakusa Akira is a spirited woman, and Atsumu finds himself already growing attached to her. He wonders if his mother lived if he would’ve spent time with her like this. Shopping for omega clothes, gossipping about the family, asking about his relationship with Kiyoomi… It’s all just everything Atsumu could want in a maternal figure. He completely understands why Kiyoomi loves her so much.

He returns with far more than he needs, but well, he had a good time and a few more omega styled clothes could always be nice to have. Seeing Akira’s bright, warm smile gives him more confidence in his choices.

Atsumu calls his dad when they arrive back in Osaka and he’s alone in his apartment once again. He’s shocked to find out that Atsumu is being courted and wants to meet Kiyoomi when he’s home in February. That’s sure to be interesting. His dad is happy for him though, so that’s a relief. The last thing Atsumu wants is for him to go into protective alpha dad mode.

Almost as soon as he ends the call, there’s a knock at his door. His vision is immediately accosted by orange.

“Atsumu-san, I got your text message!” Hinata barges his way in as soon as the door is open. He spins on his heels and gasps, snagging Atsumu’s arm. “Holy shit! You weren’t kidding!”

Atsumu eyes Hinata, who sports fresh claiming marks once again. “Nope. Omi’s ridiculous. But well, he’s my ridiculous alpha now.” Hinata matches the smirk on his face.

“I can’t believe you got your heat the day after I left. Put your shoes on, we’re going somewhere.” He does as he’s told but questions him. “You don’t have anything to help with your heats, Atsumu-san! What if you get another one and you aren’t prepared? Plus, you have needs, don’t you?”

Hinata looks at him expectantly, and Atsumu can only blush. He still hasn’t had much of a chance to try a lot with his newfound anatomy. He’s only experimented a few times. And oh, fuck. Does Kiyoomi know that he’s a virgin? Is he going to want to have sex soon? Because Atsumu would… really like that but…

“Shouyou-kun, did it hurt?”

He cocks his head. “Did what hurt?”

“Losin’ yer virginity.”

“Not as much as I was expecting. Everyone always talked about how it was so painful, and I think the nerves make it hurt more than it should. Are you thinking about having sex with Omi-san?”

Atsumu nods. “Yeah, I wanna. I’m just really nervous. He doesn’t know that I’ve never done it. Fuck, I don’t even know if he has. We haven’t even talked ‘bout it. Is it too early to be thinkin’ ‘bout this?” His words rush out as his train of thought derails from his initial point.

“I mean, you’ve known him for years, and you trust him, right?” Atsumu nods. “Then I don’t think there’s a right or wrong time. Just talk to him. Now come on, let’s go!”

Hinata’s right. He trusts Kiyoomi with everything. He’d never do anything to hurt Atsumu. And the feeling in Atsumu’s chest only tells him that this is right, that whatever he chooses isn’t going to make or break them. So if it’s not too early for that, is it not too early for… love too? His chest convulses and fills with warmth, and Atsumu smiles. Maybe it’s not.

Walking into the discreetly marked store, Atsumu isn’t sure what to expect. However, several different types of dildos sitting on display like fucking shoes isn’t it.

“Oh my god,” he mumbles under his breath.

Hinata pulls him over to one of the displays and picks up a smooth, purple silicone one. It’s not too intimidating looking, unlike the fucking monster next to it. Jesus Christ.

“You’ll want to start off small and without too much fancy stuff at first,” Hinata says. He hands the toy to Atsumu. Well, it feels fine, but he doesn't really know what he’s looking for either. “Ooh, this one is about Tobio’s size, and it vibrates!”

Atsumu automatically looks up but wishes he hadn’t. He doesn’t need to know the information that he’s now plagued with. The fact that he now knows that Kageyama Tobio has roughly a—he looks at the display sign—twenty-two-centimeter dick is now forever lodged into his brain. Thanks, Shouyou-kun.

However, as he looks at the silicone in his hand, it makes him wonder how big Kiyoomi is. Is he the same size as Kageyama? Smaller? ...Bigger? And then there’s girth to account for.

“These have inflatable knots, nice!” Hinata is already inspecting another one.

Atsumu has no idea what he’s doing. He feels like a child lost in the supermarket. He’s in a whole different world here, so he leaves Hinata to do his browsing and takes a walk around.

He walks straight past the kink aisle, he’s not ready for that. Yet, at least. Let him at least lose his v-card first, please. However, he does stop when he sees mannequins with lingerie on them. Would Kiyoomi like that? Fuck, they really need to talk about this.

Atsumu’s eyes are drawn to a lace, ruby red one. It’s an open babydoll that would tie only at the top in the middle of his chest. He’d look hot in it. At least he thinks so. Atsumu has always been drawn to lingerie, but he’s never had a reason to wear it. Obviously, it’s not like he’d wear this right away anyway. It just might be something nice to … have. Just in case. For some reason or another.

“Are you going to buy that?” Hinata asks right next to him from out of nowhere, making him jump.

“Jesus, Shouyou-kun! Ya really are like a ninja.”

Hinata laughs, patting Atsumu’s shoulder. “Sorry. But seriously, I think red is a good color on you.”

“Why not.” He grabs his size from the pile. “Are ya gettin’ anythin’?” Hinata holds up something in a box. “What’s that?”

“A bullet vibrator! This brand was recommended to me, so I wanna try it!”

Atsumu inspects the item. It’s really small. Maybe he should try one too. That should be fine, right? He grabs a box for himself.

Then with Hinata’s fiery spirit and only small amounts of embarrassment of his own, he circles back around to the aforementioned dildo displays. There are just… so many. Glass, jelly, silicone, metal… And that’s just the material they’re made out of! Hinata says it’s good to have different kinds, so being indecisive, he picks three.

So here he is checking out at a sex shop with more sex toys than he thought he’d ever own in his life. And the thing is, now that he’s accepted it, he’s honestly just ready to finally test it out. There’s a whole damn store for this stuff, so it must be pretty good. However, the real thing is supposedly better.

How will Kiyoomi react when he brings it up? When should he bring it up? Maybe he’s just getting too antsy thinking about it. But he’s positive that he wants Kiyoomi to take his virginity, deflower him, or whatever. Atsumu’s body shivers thinking about it. He really wants this.

Well, it seems they’ll be having this talk sooner rather than later.

Chapter Text

Atsumu tries to keep it in, he really does. It’s not that he’s embarrassed to bring it up, not exactly. The matter of it is that he’s nervous. How does he tell his boyfriend of, oh… about a month that he wants him to absolutely plow him? And oh, by the way, he’s a virgin. That’s just asking for an awkward conversation. But how else is Atsumu supposed to delve into it?

Ever since he tried out his new acquisitions from the sex shop, it’s becoming even more of an itch. He started with the vibrator because it’s so small, that’s just plain logic. What he was not prepared for was the absolute power behind such a tiny thing and made the mistake of starting the settings too high. Atsumu had never come so fast or hard in his life. Hinata almost peeled over from laughter when Atsumu told him.

So yeah, now he feels like some sort of repressed dam has opened the floodgates, and he’s drowning in perpetual horny energy. It does not help that Kiyoomi’s locker is right next to his in the locker room. Atsumu can smell him in all his post-practice glory and about leaks through his shorts every damn time. That can’t be normal, right?

He goes to Hinata again and gets the answer, “Oh, don’t worry about that, Atsumu-san! It happens to me too around Tobio, so I just jump him.” He’s not sure what he expected. At least it means he’s not alone in this.

Of course, it all comes to a head one evening when he’s in Kiyoomi’s apartment, and things start becoming a bit more heated.

Kiyoomi slips a hand underneath Atsumu’s shirt, slowly brushing up his side. The warmth Atsumu feels elicits a gasp, allowing Kiyoomi’s tongue in without any protest. His strong body hovers over Atsumu from where they’re laying on the couch, and Atsumu likes this position. So does Kiyoomi if his rising scent is anything to go by. However…

Regretfully, Atsumu pushes on Kiyoomi’s chest, making him pull back. “Is everything alright?” he asks.

“Yeah, I just—” Atsumu shifts his body, looking away from Kiyoomi. “I wanna talk to ya ‘bout somethin’.”

Sensing the seriousness of the impending conversation, he sits up and offers Atsumu a hand to pull him upright as well. Taking it, he keeps his hand in his, playing with Kiyoomi’s long, slender fingers. He can feel those deep eyes staring at him, waiting for an elaboration.

Now that he’s here, how is he supposed to continue? No one teaches the etiquette behind these kinds of conversations. Is there even one to begin with? Atsumu knows that Kiyoomi won’t make fun of him or anything of the sort, so why is he this nervous? Perhaps it’s the inherent vulnerability of putting himself out there like that.

“Hey,” Kiyoomi cups his face, “you know you can tell me anything, right?”

Atsumu nods and takes a deep breath. “I wanna have sex with you!” he blurts out and immediately feels his face flame. Nice job, Atsumu.

Kiyoomi’s lips twitch, and he strokes Atsumu’s red cheek with his thumb. “I’d like that. Though something tells me that there’s something else bothering you.”

His boyfriend really is the best. Most people probably would have laughed in his face, but not Omi. Not when he knows this is something important. And well, at least Atsumu knows that Kiyoomi wants this too.

“I’ve never, um, been with anyone before.”

“Oh.” The surprise is clear on Kiyoomi’s face. “And you want to? With me?”

“Yeah, I do.” Atsumu places a hand over Kiyoomi’s, leaning into his touch. “Have ya ever…?”

“I have.”

The slightest prick of jealousy invades Atsumu’s chest, but in all honesty, he’s glad. At least one of them will know what they’re doing, and Kiyoomi will take care of him, guide him. Experience is a good thing, he tells himself. However, one fear lingers in his mind.

“So yer okay with me not bein’ any good?”

Kiyoomi’s other hand comes to cradle his face. “Atsumu, anything with you will be good because it’s you I’ll be with.”

“Omi…” Atsumu’s eyes gloss with unshed tears, and he pulls Kiyoomi forward to press their foreheads together. The affection bubbling in his chest for this man transcends anything Atsumu can describe. Maybe it’s because he’s never felt this way before that he can’t quite put it into words. And just maybe Atsumu knows that this can only be one thing.

“If we’re on the same page here, we’ll let things happen naturally. Is that okay?”

“More than okay,” Atsumu says, smiling as he closes the distance between their lips.

Chocolate isn’t hard to make. He’s been doing it since high school, so he’s practically got it down to a science. Though he does like to mix it up sometimes with different flavors or styles. His teammates have always seemed to enjoy his offerings on Valentine’s Day. However, this year is the first year he’s making them for someone special, and it makes all the difference. This is honmei choco.

Kiyoomi likes dark chocolate, so that’s what his new heart-shaped molds contain as he sets them in the refrigerator. Everyone else gets milk chocolate in a square. Atsumu adores his friends, but the heart shape is reserved for Kiyoomi only.

Valentine’s Day is tomorrow, and Kiyoomi has insisted that he take Atsumu out to dinner even though alphas typically aren’t the ones expected to do anything. Okay, now that he thinks about it, maybe that’s why his teammates used to give him questioning looks when he gave them chocolates for the first time. He just likes to show his appreciation for the people he cares about, okay?

Walking to his bedroom, he glances at the bag he set on his dresser. It’s the one that contains the lingerie that he bought. Originally, he had said that he wouldn’t wear it for his first time, but the more he thinks about it, the more he wants to. Atsumu wants to impress Kiyoomi and look good for him. And yes, he agreed to let things happen naturally, but what if he wants to be stupid and cliché and have sex on Valentine’s Day? They don’t have morning practice the day after, so it’d be perfect.

Hopefully, Kiyoomi will be on board with this. He will be, right? Atsumu hasn’t even tried it on. Maybe that’s just asking for a bad omen, but maybe it will also determine how he feels about the situation tomorrow. Sure, he’ll just entrust the fate of his virginity to a skimpy piece of clothing. Sounds good. Yeah. Totally.

The next day at practice, Atsumu has a small bag with chocolates in it for everyone on the team and Coach Foster, of course. However, the heart-shaped box in his hands is for a certain alpha. The alpha that makes Atsumu feel like he’s floating, yet on steady ground. The alpha that Atsumu sees even in his dreams and makes him yearn to wake so he can feel that warmth in reality. The alpha that Atsumu has grown to know and accept just as he’s done in return.

In the locker room, he hands out his treats, which everyone accepts gratefully. Hinata hands out his own as well. Barnes looks about ready to tear into his. It’s a well-known fact that he has the biggest sweet tooth. They often joke that Barnes has a hollow leg with how much he consumes.

Before Kiyoomi begins changing into his practice clothes, Atsumu approaches him with the chocolates in hand. “Omi-Omi! Happy Valentine’s Day! I made ya these, so I hope ya like ‘em.”

He takes the box and undoes the shimmering ribbon wrapped around it. Lifting the lid, he smiles at the contents. “Dark chocolate?” Atsumu nods, biting his bottom lip. “Thank you, it’s perfect. Happy Valentine’s Day”

Kiyoomi leans in, giving Atsumu a chaste kiss. Though it’s only brief, his heart swells and bursts in his chest. He really can’t wait for tonight.

Before he is supposed to meet Kiyoomi at his apartment, Atsumu has a mild freak out. Yes, they’ve gone out to dinner several times, but this is the first time it feels like a big deal. Kiyoomi only told him to wear something nice. That can mean anything! How nice is nice? Is it better to be overdressed or underdressed? The sheer amount of spam texts that he’s sent Hinata should be embarrassing, but Atsumu is only slightly on edge.

He’s freshly showered, shaved, lotioned, brushed… is he forgetting something? Well, he needs to decide on a damn outfit before he styles his hair. Actually, maybe he could wear one of the new outfits he got when he went shopping with Akira.

Digging through his closet, he pulls out a shimmery light blue bow-neck shirt and white pants. Atsumu lays them out on the bed and snaps a photo to send to Hinata. He receives a response with several exclamation points and emojis.

After dressing and putting on his bracelet, he styles his hair then assesses himself in his full-length mirror. Atsumu looks different. A good different. A different that makes his eyes shine golden in the light, makes his rough edges just a bit softer, makes him… happy. Of course, the physical changes of his body are even more apparent now than even just last month. He has what Hinata calls an hourglass figure. Maybe that’s why Kiyoomi is constantly touching his waist, not that Atsumu is complaining.

He checks the time and sees he should head out soon. His overnight bag is packed, and he’s triple-checked that he has everything. Everything. Taking a deep breath, Atsumu steadies himself. He’s got this.

Kiyoomi answers the door quickly once Atsumu knocks, and dammit, he has no right to look that good. Clad in a single-breasted, black waistcoat over a white button-down with black dress pants, Kiyoomi takes him in.

“You look amazing,” he says.

Atsumu’s cheeks flush, happy to have his alpha’s approval. “Thanks. So do ya, Omi.”

He takes Atsumu’s bag, placing it inside the apartment before stepping out and locking it behind him. “Ready?” Atsumu nods, taking Kiyoomi’s offered hand.

Atsumu knows that Kiyoomi has a car, but he’s never ridden with him before. Now, however, he wishes it stayed that way. For as meticulous as he seems, he is not a good driver. He drives like he’s the getaway driver in a heist.

Gripping the leather seat on either side of himself, Atsumu watches in horror as the car weaves through traffic. Sakusa “yellow means floor it” Kiyoomi. Atsumu is pretty sure that he still ran that last red light.

“Omi, holy fuck! Slow down!”

“What’s wrong?” He sounds genuinely confused. “The speed limit here is hardly efficient, and my reflexes are more than capable of preventing an accident.”

Oh lord, Atsumu is going to die. He’s actually going to die here as a virgin on Valentine’s Day. That’s not tonight’s goal. In fact, it’s the complete opposite. Oh boy, and then Osamu will find his bag at Kiyoomi’s apartment with lingerie in it. Then he may just expire right then and there. Suna will then proceed to share these moments in his eulogy speech, so everyone will know.

Atsumu is so lost in planning his metaphorical funeral that he doesn’t realize that they’ve arrived until Kiyoomi opens the passenger door for him and holds out a hand. “Atsumu, are you okay?”

Unbuckling himself, Atsumu smiles and takes his hand. “Yeah, sorry. I was just thinkin’.”

He recognizes where they are immediately. Abeno Harukas is the tallest skyscraper in Japan, making it very distinctive. Atsumu has never had a reason to come here himself though. Honestly, he’s not even sure what’s here. To him, skyscraper equals office buildings. But he’s sure Kiyoomi wouldn’t bring him here for that.

“I probably should have asked earlier, but you’re not afraid of heights, right?” Kiyoomi asks him as they walk into the building.

“Nope! At least, I don’t think so.” It’s not like Atsumu has ever really tested it. Why would he?

In the elevator, Kiyoomi presses the button for the 57th Floor. Oh, so they’re really going up, huh? Kiyoomi’s thumb strokes the back of Atsumu’s hand, and he leans into his boyfriend slightly. Even in this shoddy elevator lighting, he looks good. And why does he smell so good? Atsumu would be happy just cuddling together at home wrapped in his scent.

The restaurant is obviously crowded since it’s Valentine’s Day, but of course, Kiyoomi gets them a table next to the window. Everything about this date is fancy and romantic, and with how handsome Kiyoomi looks, Atsumu couldn’t ask for anything more. His dimples are on full display as he smiles freely over the candlelight, and dammit, Atsumu loves this man.

He doesn’t care if it seems fast or too early or any of that nonsense. No one can tell him how he feels, and the way he feels about Sakusa Kiyoomi infinitely surpasses any tangible marker of love that he can describe. It’s more like… volleyball. The constant thrum in his chest that bursts with passion, excitement churning in his stomach. A genuine desire for more that keeps him longing, waiting for the next moment to carry him with a weightlessness only existing at that juncture of the perfect play.

To many, it may sound insulting to be compared to volleyball, but in Atsumu’s world, there is no greater compliment or higher standing. For if he can’t liken his lover to volleyball, are they really the one in the first place?

Out the window to his left, the sun sets over the city. Orange along the skyline seemingly bleeds into the streets where the lights flicker to life. Looking back to Kiyoomi, he lets out a small laugh. Some ice cream served from some stupidly fancy glass cups remains on the corner of Kiyoomi’s mouth.

“Ya got a little somethin’ there, Omi.” Atsumu reaches over the table and gently wipes it off with his thumb. Bringing it to his own mouth, he licks it off his finger and smirks when Kiyoomi’s eyes darken just the slightest bit.

After dinner, Kiyoomi takes him up to the observatory. The view is immaculate. He can see all of Osaka from here. By now, the sun has set, so all the lights below look like stars in between the lines of the glowing, golden roads.

As he’s looking out the window, Kiyoomi wraps his arms around his waist from behind and rests his chin on Atsumu’s shoulder. He rests his hands on top of Kiyoomi’s and leans back into him. Even sixty stories above the ground, Atsumu feels secure in Kiyoomi’s arms.

“Thank ya for tonight, Omi.”

He hums next to Atsumu’s ear, and the vibration sends a small shiver through his body. “It’s my pleasure,” Kiyoomi says and leaves a soft kiss on his cheek.

Atsumu wiggles around in his hold to face his alpha and takes his phone out of his pocket. “Let’s take a picture!”

He’s almost half surprised that Kiyoomi easily agrees and moves to wrap a single arm around his waist. “Here, I’ll take it.” Taking the phone, he angles it to capture them both in the image. “One more.”

Atsumu smiles at the camera, but then his chin is turned with gentle fingers and his lips are captured. The camera shutter goes off as he smiles into the kiss. Breaking away, he makes grabby hands for his phone.

Both pictures are perfect. Atsumu may have once agreed with his high school’s motto, but recently, he wants to indulge in every memory he can. Memories full of happiness and love are something he wants to keep forever.

Atsumu looks at himself in the mirror in Kiyoomi’s bathroom. The ruby-red compliments his skin tone and really brings out the blonde of his hair. He looks good. The lace falls just below his butt and shows off his thick, toned thighs. The sheer panties don’t leave much of anything to the imagination.

His heart beats wildly as he realizes that he’s actually going to do this. He’s really going to sit himself out there, scantily clad, and ask Kiyoomi to fuck him. Atsumu is hot, right? There’s no way his alpha will turn this down. His own inner omega turns in circles, acting like an excited dog. Well, if his omega has confidence, he should too! Taking one last glance, he makes sure the coast is clear before dashing into Kiyoomi’s bedroom.

After putting his clothes away, he stands there just staring at the bed. Should he just… get on it and pose? Kiyoomi is waiting for him in the living room, and he’s taken a while as it is. Making an executive decision, Atsumu climbs on and kneels in the middle of the bed, sitting back on his heels.

“Hey, Omi? Can ya come here?”

Oh fuckfuckfuck, this is happening. This is actually happening.

“Is everything o—” Kiyoomi stands in the doorway, his eyes trained on Atsumu’s figure. The scent of arousal permeates the air, and Atsumu can see his adam’s apple bob low. Kiyoomi approaches slowly, never taking his eyes off of him.

Atsumu shuffles his weight, trying to remain confident. “Is this okay?”

“If you’re sure, of course, it is.”

“I’m sure.”

Kiyoomi climbs on and gently cups his face with one hand and holds his waist with the other. “God, you’re beautiful.”

As their lips meet, Atsumu melts into it. With nimble fingers, he starts unbuttoning Kiyoomi’s shirt. His heart pounds, feeling the warmth of Kiyoomi’s bare skin radiating off of him more and more as cotton fabric falls to the floor.

He’s seen Kiyoomi in several states of undress before, but this is different. Here Atsumu can caress every lean muscle and kiss every mole hidden beneath clothing. Kiyoomi rubs gently up and down Atsumu’s side, licking into his mouth and tangling their tongues together. Lowering his hands, Atsumu pulls at Kiyoomi’s belt, making quick work of it.

With an arm wrapped around his waist, Kiyoomi lowers Atsumu down onto his back and begins kissing down his jaw and neck. The small gasp that leaves his lips when Kiyoomi laps at his scent gland startles him slightly. He holds the back of Kiyoomi’s head, pressing him closer from where he hovers over Atsumu.

Kiyoomi’s lips continue their assault down to his chest where he pulls back slightly to look Atsumu in the eye. “Okay?” he asks, fingers hovering over the ribbon tying the front of the lingerie together.

When Atsumu nods, the bow unravels. His hands splay over Atsumu’s bare chest, roving over his pert nipples and down to his waist. Grabbing on, Kiyoomi leans down to nip at the pink bud and take in the heady scent permeating from the area.

The warmth of Kiyoomi’s mouth and hands envelopes him in a state of greed. Being touched like this feels so good, and he wants more. Atsumu can feel himself getting wet, preparing for his alpha.

“You smell so good, Atsu,” Kiyoomi groans.

Trailing down further, hot breath breezes over Atsumu’s covered erection. He looks up to Atsumu once again before continuing.

“Omi, please. More.”

With his answer, Kiyoomi slowly hooks his fingers under the lacy material and slides it down Atsumu’s legs. Sitting back, his eyes rove over Atsumu’s nude body greedily.

He smooths his hands down Atsumu’s thick thighs, massaging firm muscles. Capturing his left leg and lifting it onto his shoulder, Kiyoomi presses wet kisses down Atsumu’s inner thigh, nibbling at the soft skin.

The sensations tickle and warm Atsumu, allowing him to melt in his alpha’s hold. Kiyoomi’s fingers drop lower, gathering slick from his thighs and trail under his dick. Atsumu’s breath hitches as he feels a finger tease at his entrance. His walls tighten at just the tip, unexpectedly sensitive to a lover's touch.

Slowly, Kiyoomi inserts a finger, letting Atsumu get used to the feeling. His breathing quickens at the touch—at how different it feels to his own. Pumping in and out, Atsumu’s hips twitch, vying for more. Soft ahs and Omis leave his parted lips.

His walls stretch more when Kiyoomi adds another finger, continuing his attention to all of Atsumu’s sounds, aiming to pull each and every one out of him. He kisses Atsumu gently, his tongue licking into Atsumu’s mouth to feel every inch he has to offer. Kiyoomi’s other hand rubs up and down Atsumu’s pliant body, feeling every expanse of skin with those callused fingers.

When Kiyoomi presses against his inner walls, Atsumu moans, bucking his hips. Slick gushes from his core, and Kiyoomi can no longer restrain himself from tasting the source.

At the first lick, Atsumu twitches at the unfamiliar touch. However, as the licks become more firm, he lets out a ragged breath. An unforgiving tongue delves into his heat. Kiyoomi loops his arms around Atsumu’s thighs, keeping them and his hips locked in place. The tingling sensation in his legs grows as they shake from the repeated assault of his clitoris.

“Omi! Ah— O—” He grips the bed, clawing at the sheets. Feeling his body wind up, taught for release, burning with heat—Atsumu wails as it releases, waves of pleasure washing over him. Kiyoomi licks him through it, sucking at the skin around his entrance.

Atsumu’s chest heaves. “Oh my god.”

“You okay, baby?”

“Yeah, keep goin’. Fuck.”

Kiyoomi gets up to remove the rest of his clothes and retrieve a condom while Atsumu catches his breath. Atsumu has never had an orgasm like that before. Jesus. His gaze shifts to Kiyoomi, and his eyes bulge.

There’s no fucking way. No way in hell that’s going to fit. His inner omega preens, keening at having such a well-endowed alpha. However, Atsumu’s momentary panic overrules. It’s obviously bigger than any of his toys, but fuck!

Kiyoomi returns with a condom rolled on and must see the panic on his face. “Hey, we don’t have to do this if you’re unsure,” he says, placing a soothing hand on his thigh.

“I— I just… Yer fuckin’ huge!”

“Thank you.”

“No, you ass! That’s not gonna fit!”

“Yes, it will. I can show you. Do you want to try?”

Atsumu whimpers, scared and turned on at the same time. “Yes, but go slow. Promise?”

Kiyoomi drops down to place a kiss on his lips. “Promise. Just tell me to wait or slow down and I will.”

Atsumu feels something big line up at his entrance. He tries to relax, but he’s so fucking nervous. As soon as he feels the slightest breach he panics a bit.

“Wait!” Kiyoomi pauses, waiting for Atsumu to calm down. Slowly, he relaxes his muscles. “Okay. ‘M good.”

One of Kiyoomi’s hands rests on his hip. His thumb rubs soothing circles as he presses in a bit more. The stretch is so much. Atsumu feels like he might rip open.

“Omi, wait!” Atsumu tries to relax again, throwing an arm over his eyes. “Is it almost in?”

“Atsumu… That was just the head.”

“Oh my god!”

“Do you want me to pull out?”

“No! Just— give me a minute.” Taking a deep breath, he removes his arm and looks up at Kiyoomi. “‘Kay.”

Slowly sliding in more, Kiyoomi controls the urge to thrust inside Atsumu’s warmth. He keeps pushing forward until he bottoms out. “Alright. I’m all the way in.”

Atsumu feels so full. It’s like he’s stuffed to the brim. Omi is inside him. Feeling a bit overwhelmed, he reaches out for Kiyoomi to come closer and wraps his arms around his back.

“Okay, ya can move.”

Holding Atsumu’s hip with one hand and bracing himself with the other, Kiyoomi slowly draws back before pushing back in. He kisses Atsumu’s cheek and down his jaw as he does it again. And god, it’s weird. It’s not even like a dildo, really. His alpha is so much bigger and just having Omi’s presence over him like this eases any kind of self-doubt.

When Kiyoomi begins working up a steady rhythm as Atsumu relaxes, that’s when it changes for him. His alpha’s cock thrusting in and out, sliding easily with the slick, rubs over his clit buried inside his walls every time. The gentle press is maddening, causing Atsumu to keen and claw at Kiyoomi’s shoulders.

“Ah— Omi, faster. Please!”

Kiyoomi adjusts his hands, settling on Atsumu’s waist. “You’re doing so good, Atsu. So perfect.”

Atsumu moans, grabbing onto his forearms as the pace increases. Atsumu isn’t sure what to do other than just take it. All the new sensations consume his nervous system, overflowing with information. Yet, it somehow still isn’t enough.

“Omi, more. Don’t hold back.”

Kiyoomi’s dark eyes seem almost completely black, filled with lust and alphan desire. He buries his face in Atsumu’s neck groaning. “Fuck. Atsu, you can’t just—” His hips continue without fail as Kiyoomi fights with himself, and he gives a particularly hard thrust.

“Alpha!”

That’s all it takes for Kiyoomi’s resolve to crumble. His body stiffens momentarily before his hold on Atsumu’s waist tightens, and he begins to pound into him. The pheromones thick in the air make their minds hazy, furthering their lust and need for each other.

“Fuck, Omi! Oh god!” Atsumu keens, throwing his head back in pleasure.

Kiyoomi takes the chance to bite and nip at the sensitive skin of his throat. “You feel so good, baby.”

His bruising grip shifts to wrap an arm underneath Atsumu and around his waist, taking full control of how his body moves, cradling him in his strong arms. Atsumu wraps his legs around Kiyoomi and clings to his back, surely leaving angry red scratches behind.

Baring more of his neck, Atsumu says, “Bite me, Omi.” He wants those claiming marks. Everywhere.

Kiyoomi doesn’t have to be told twice and sinks his teeth into the gland, reveling in the sensation, fucking into Atsumu harder, faster as he screams in pleasure, coming again as his walls contract around Kiyoomi’s cock. The sound of Kiyoomi’s hips slamming into him combined with the wet squelching of slick as he pistons in and out accompany Atsumu’s blissed-out moans. But Kiyoomi isn’t done. He releases the gland and immediately shifts to bite on the other side.

“Kiyoomi!” Atsumu wails as teeth sink into him again. The pain is nothing compared to the pleasure he feels. His body convulses, vaginal walls contracting as another flood of endorphins slam through his body. Back arching off the bed, Atsumu feels tears escape the corners of his eyes from the stimulation.

“Atsumu, I’m going to come soon,” Kiyoomi pants next to his ear.

“Yes, yes. Please!”

With a deep rumble in his chest, Kiyoomi slams into Atsumu to chase his release. His free hand skims down to grab Atsumu’s untouched dick and starts pumping him along with each thrust. With the overwhelming amount of stimulation Atsumu is getting—his dick, his clit, his prostate—he can’t make anything coherent out of his babbling.

“I’ve got you, Atsu,” Kiyoomi says. So caught up in their pleasure, neither notice as Kiyoomi’s knot pops, catching on Atsumu’s entrance as he shoves his cock in further, grinding into Atsumu.

As the knot swells to full size, Atsumu comes once again squirting cum between them with his cock twitching in overstimulation. Kiyoomi strokes him through it, still fucking into him as the ripples of his duel orgasm leave him limp in Kiyoomi’s arms.

Kiyoomi comes with a deep moan, face buried into Atsumu’s neck. “I love you. Fuck, I love you.”

Atsumu lays on top of Kiyoomi, held tightly to his chest, and fingers gently stroke his hair when Atsunu’s mind comes back to him. Kiyoomi must have flipped them over. There’s a lot to process here. First, holy fuck. Second, when can they do that again? Third, why did Kiyoomi’s knot pop? And fourth… did he just say—

“Omi? Did… didja mean that?”

Kiyoomi raises his head up slightly to look Atsumu in the eye. “Yes. I know you shouldn’t admit things like that for the first time in passionate moments, but I mean it. I love you, Atsumu.”

He cradles Kiyoomi’s face. “I love ya too, Omi.”

They kiss languidly, just enjoying the comfort of each other, exchanging their love with each press of lips. Held in his alpha’s arms, sated, and filled with contentment, a soft fluttering sound emits from Atsumu. He pauses his ministrations, surprised.

“You’re purring,” Omi says in awe, fondness clear in his eyes.

Atsumu lays his head down and nuzzles into Kiyoomi’s chest, letting himself bask in this moment. He hums, listening to Kiyoomi’s steady heartbeat. “Ya knotted.”

Typically, alphas only knot during their rut or an omega’s heat. While it’s not unheard of to happen outside of those two instances, it doesn’t happen to everyone.

“I did. I’ve heard of it happening when an alpha and omega pair are highly compatible. So that’s what I’m going to believe.”

Atsumu likes the sound of that. He’ll choose to believe that too.

“So, uh, when yer knot goes down… We’re doin’ that again, right?”

Kiyoomi raises an amused eyebrow. "Well, I didn’t get to put a claiming mark here.” He rubs two fingers on the nape of Atsumu’s neck.

“Hm. What a travesty. It oughtta be rectified.”

Kiyoomi’s knot has gone down enough for him to slip out and he rolls them over, eliciting a laugh from Atsumu. “Immediately.”

Chapter Text

Walking into practice with Kiyoomi the next day, Atsumu is only a little sore. After their second round, his alpha took care of him. They took a hot bath together and then went to sleep with Atsumu purring on Kiyoomi’s chest. Well, after the sheets were changed because Atsumu may or may not have leaked an embarrassing amount of slick everywhere. Towels next time.

Honestly, what hurts the most is the claiming marks and the other bite marks Kiyoomi left. They just sting a little, and Atsumu definitely isn’t complaining. He knows Kiyoomi isn’t sorry either.

When their teammates greet them, there is absolutely no denying what happened last night. Hinata tilts his chin down and sends him the most devilish smirk. Bokuto asks if they had a fun evening, which Kiyoomi quickly counters by asking him the same. It doesn’t have the intended effect as he goes on to moon over Akaashi.

While Kiyoomi is reluctantly occupied, Hinata pulls Atsumu aside.

“So?” he asks with a huge grin.

Atsumu tries not to smile or burst out into silly little squeals because that’s just unbecoming of him with his teammates around. “Shouyou-kun, holy fuck!”

“I take it that it was good? Give me the details!”

“Try fantastic!” He feels like a high school girl sharing secrets about her crush as he lowers his voice. “His dick is so big. I thought it was gonna hurt so much, but ya were right. It wasn’t that bad. And Omi was so good to me.”

“I can tell.” Hinata wiggles his eyebrows and eyes the marks on Atsumu’s neck. “Just wait until your heat. That’s an entirely different experience.”

At the mention of his heat, Atsumu pales. If he’s on schedule, his heat will be in about a month. His first one was absolute hell. This one won’t be like that, right? Atsumu starts unconsciously outputting anxious pheromones.

“Wah! I’m sorry, Atsumu-san! I’m sure everything will be fine this time!”

Before Hinata can do much to calm him, Kiyoomi is already embracing him. Atsumu presses his face into the crook of his neck, inhaling his calming scent. A hand pets his head soothingly.

“What’s wrong, Atsu?” he asks.

“I just remembered my heat is next month, and I’m scared.”

“I’ll be there to help you in any way I can. If you want me to that is.”

Atsumu hugs Kiyoomi tightly around the waist. “I do.”

Kiyoomi kisses his temple and releases him as they’re called to get to the gym. Walking next to his alpha, Atsumu feels his heart flutter. Omi really does take such good care of him. Atsumu hopes that he’s able to return the favor.

Atsumu is making dinner for Kiyoomi and himself when his cell phone rings. It’s Osamu, which isn’t all that strange, but he could have sworn Suna was coming down this weekend.

He accepts the call and tucks the phone between his shoulder and ear. “What’s up?”

“Just lettin’ ya know that we’re ‘bout half an hour out.”

Atsumu furrows his brows. “What do ya mean?”

“Please tell me ya didn’t forget.”

Atsumu definitely forgot. “Omi’s here right now.” He glances over to the couch where Kiyoomi looks over at the mention of his name.

“Well, good. Pa wants to meet him.”

Atsumu freezes, almost dropping his phone right into the wok. “Shit!”

“So ya did forget,” Osamu’s voice drawls with no inflection.

“No, it just,” he picks up the small calendar that sits on the counter, “snuck up on me.”

“Right. Well, be prepared ‘cause I’m starvin’.”

“Yeah, yeah. I got it.”

“See ya soon then.”

The call disconnects and Atsumu has yet to resume cooking. Kiyoomi is still looking at him, now with a raised eyebrow. Atsumu looks from him to the food that will definitely not feed Miya Osamu.

Turning back to Kiyoomi, he asks, “How do ya feel ‘bout take-out?”

Atsumu sits on the couch with his legs thrown over Kiyoomi’s lap. He’s trying to play it cool, but Atsumu can feel him tensing and relaxing again and again. At least he has a little bit of a heads up, unlike Atsumu who got absolutely nothing before meeting his parents.

However, Atsumu takes pity on him and scoots closer to wrap his arms around Kiyoomi’s middle and releases calming pheromones. Kiyoomi sighs, pressing Atsumu’s head to his chest and snakes an arm around his waist. He can feel the tension in the alpha’s body release.

Atsumu knows that his dad will love Kiyoomi. Not only is he an amazing person, but he’s a good alpha and takes care of Atsumu. Though mainly it’ll be because Atsumu loves him that his father will too. Though Atsumu does wonder how his dad will react to seeing him as an omega after all these years.

When there’s a knock at his door, he supposes he’ll be finding out in just a moment. Kiyoomi squeezes him tighter for just a moment and kisses his temple before releasing his hold. Atsumu adjusts the turtleneck that he threw on. He doesn’t want his claiming marks blatantly showing during the first time his dad meets his alpha.

Atsumu can’t help his trot to the door; he’s excited and hasn’t seen his dad in almost a year. Opening the door, he’s met with two neutral faces and one with a smile that crinkles his eyes.

“Welcome back, Pa.”

Before he can do much else, he’s being embraced. “It’s good to be home.” Then his father pulls back and holds him by the shoulders, assessing him. “Ya look so much like yer ma.”

Atsumu’s chest fills with warmth. He’s seen pictures of his mother. She was absolutely stunning. She had long chestnut brown hair and honey-colored eyes much like his own.

Kiyoomi comes to his side after their initial family reunion and introduces himself with a bow.

“So you’re the alpha I’ve heard about.” He eyes Kiyoomi from head to toe, not quite posturing, but definitely appraising his worth. Atsumu suppresses the urge to roll his eyes while Suna and Osamu exchange tired glances.

“Yes, sir.”

Then his dad smiles and claps Kiyoomi on the shoulder. “Welcome to the family.”

Atsumu bites his bottom lip to keep from laughing at his boyfriend who stares ahead with wide eyes and his mouth slightly agape. It seems he didn’t believe Atsumu when he said his dad is just a big softie.

Not long after everyone gets settled, the food arrives. Kiyoomi goes down to get it while everyone else retrieves plates. Honestly, Atsumu isn’t sure why they all decided to gather here at his tiny ass apartment. Osamu’s is much more spacious.

When Kiyoomi returns and everyone is served, Atsumu smiles at the sight before him. This is his family. They may be small in number, but he loves every single one of them dearly. While it has always just been Osamu and Atsumu, now he truly sees that they both have others they can rely on as well.

“Hey, ‘Samu, what’re ya wearin’ to the end of the season banquet?” Atsumu sees both Osamu and Suna freeze and knows he said something wrong, but he has no idea what.

“I’m not goin’ to the banquet.”

“Why not? Ain’t Sunarin bringin’ ya?” When Osamu puts his food down, Atsumu knows this is serious.

“I said no.”

“Why?” He glances at Suna who has his head turned down.

“Ya know why. What would people say if a male beta brought an alpha as his plus one?”

“Fuck other people.”

“Ya know as well as I do that it ain’t that easy.”

Truthfully, Atsumu knows that he’s right. Not only could it affect Suna’s potential sponsors, but it could also impact Osamu’s business. Why do they live in a world where other people concern themselves with who someone else loves? It doesn’t hurt them or affect them in any way. Why are people so short-sighted?

Atsumu has a few other opinions on Osamu and Suna’s hidden relationship, but he won’t share them right now. He doesn’t want to disrupt their evening any more than he already has. Though he knows they won’t be able to hide it forever. He fears that it’s going to come out in a less than desirable way.

“I do. Just be careful, ‘kay?”

Osamu nods and resumes his meal. Atsumu hopes that both he and Suna know that they have so many people that would stand behind them. He himself would be right there leading the cause.

“Why is it so tight?!” Atsumu asks as Hinata pulls the laces.

“It’s a corset! It’s supposed to be tight, but not so tight you can’t breathe. You can still breathe right?”

“Barely,” he grumbles. Somehow Hinata has convinced him to wear a corset vest because they’re all the rage in omega fashion, Atsumu-san! Apparently. Yet for some reason, Hinata is not wearing one of these things to the banquet himself. Instead, he’s wearing a navy jumpsuit with wide-fit legs and has sheer lace arms and at the top. It looks far more comfortable.

“There!” He steps back and looks Atsumu up and down. “You look great! Omi-san will totally pop a knot!”

Atsumu chokes. Jesus Christ.

Walking over to the mirror, he looks himself over. He does look pretty good. The white vest with gold accents and black paneling on the sides looks sharp over the black dress shirt and tie. His waist looks tiny, but he feels like his ass looks huge.

“Shouyou-kun, does my ass look fat?”

“Not in the way you’re implying.”

Atsumu whips his head around. “What do ya mean by that?!”

“Your ass isn’t fat, but you’ve got a phat ass. It’s a compliment!”

Atsumu isn’t sure how to feel about that, but it’s a bit too late to do anything about it. Hinata exiled Kageyama so Atsumu could come get ready with him. That left him to get ready with Kiyoomi. He’s pretty sure their boyfriends have never been left alone together, and the image of them being awkward as hell comes to mind with their dumb frowny faces, making him laugh quietly to himself.

Soon enough, there’s a knock at the door, signaling that their alpha boyfriends are here to collect them. Atsumu can’t deny that Kageyama is attractive, but no one holds a candle to Kiyoomi. It should be illegal for him to wear a three-piece suit. Black on black? Atsumu’s heart isn’t strong enough for this.

It seems Kiyoomi has similar thoughts because his pupils dilate, and he grabs Atsumu by the waist, pulling him closer. His hands are so big. They almost make Atsumu feel small.

“You look gorgeous. You’re only missing one thing.” Kiyoomi raises a hand, baring his wrist. “May I?”

Atsumu nods and tilts his head, giving open access to be scented. Kiyoomi rubs his wrist over the scent glands. It’s something pretty basic, but Atsumu loves how intimate it feels. The act relaxes him when he hasn’t realized how tense he actually was. This is his first big event openly being an omega. Perhaps he’s a little nervous.

Kiyoomi finishes by placing a soft kiss on his cheek. “Perfect.”

Though he doesn’t think he’ll have much to worry about with Kiyoomi here by his side.

The four of them walk into the ballroom of the hotel. There are already numerous people milling about. Surely this won’t be too different from previous years, right? Kiyoomi keeps a hand at the small of his back as they find a table. Bokuto waves them over to sit with him, Akaashi, Kuroo, and Tsukishima.

Taking a closer look at his fellow omegas, he spies a bonding mark on Tsukishima’s neck. Kuroo wears a matching one as well. So he ended up doing it. Good for them. Then around Akaashi’s slender neck is a beautiful black velvet collar with a teardrop pearl hanging from it. He raises an eyebrow and shoots a glance at Bokuto. He just smiles broadly and throws an arm around Akaashi’s shoulders. Atsumu won’t be surprised if there’s a bonding mark there the next time he sees Akaashi.

Hinata sees Atsumu looking and leans over to whisper, “They had a synced rut/heat cycle in January and sealed the deal. Tsukki’s been really happy.”

He takes another look at Tsukishima. At first glance, it seems like he’d rather be anywhere else, but when his eyes wander to Kuroo, the look of contentment and small smile speaks volumes.

“I think Bokkun is gonna be followin’ that example real soon.”

“Probably. Tobio and I have talked about it too.”

Atsumu pulls back slightly to look Hinata in the eyes. While his first reaction is surprise, in all honesty, he’s not. As he’s thought before, Kageyama and Hinata are what true mates probably look like if they really exist. Actually, Bokuto and Akaashi fit that notion too. There’s no one else that could possibly fit them better.

Now that he’s with Kiyoomi, he’s had a taste of what a connection between an alpha and omega is like. Atsumu thinks that there’s no one else better suited for him either. With the draw his inner omega feels towards Kiyoomi, it seems like there’s something beyond just instincts at play. At heart, Atsumu is a hopeless romantic, and maybe he wants to believe that true mates are real. Then perhaps Kiyoomi was always meant to be his.

“So ya think yer gonna durin’ offseason?”

Hinata nods. “Yeah. I think so. I know you’re new to all this, but have you ever thought about it?”

He hasn’t, but now he is. It’s not that he’s never thought about it because he doesn’t want to, he’s just had his mind occupied by other things. Bonding with Kiyoomi… His heart swells in his chest, and his inner omega purrs. Yeah, he’d like that. It’s too soon right now; he knows that. However, in the future, it’s definitely something he wants to do.

“I have now,” he says with a chuckle. Hinata’s shoulders shake in their shared mirth.

“Hey, what are you talking about?” Kageyama asks.

“Omega stuff, To-bi-o~,” he says cheekily earning a headlock from his alpha.

Tuning back in, the rest of the table is on a completely different topic, and Atsumu wonders when they’re going to be served. He’s starving.

After dinner, the obligation of talking to sponsors begins. Atsumu is both surprised and unsurprised that he’s a person of interest tonight. The amount of times he’s been asked solely about his omega status is really starting to piss him off. Don’t these rich fuckers have better things to worry about? Is gossip their only source of entertainment?

“And you’ve already landed yourself a successful alpha. I wish I could say the same for my daughter. The biological clock waits for no one,” some old geezer drones on. Atsumu zones out, trying to remain calm.

Of course, Kiyoomi is a successful alpha, but Atsumu is a successful omega too, dammit! No one gave a fuck about any of this last year when he was an alpha. Now it’s all roundabout talk of his fertility.

Kiyoomi’s presence is the only thing keeping him from doing something rash. His inner omega’s hackles are raised and its pride is hurt with doubts of its fertility. When Atsumu spies Suna lurking alone, he tells Kiyoomi he’ll be right back and excuses himself. He needs to step away, and his friend looks in need of assistance.

Suna is leaning against the wall with a glass of champagne, looking downright gloomy. Atsumu knows it’s because Osamu isn’t here. The whole reason he isn’t is so Suna’s sponsorships wouldn’t be affected, and that face is doing him absolutely no favors. Something must be done.

“Sunarin,” Atsumu stops in front of Suna and reaches out, wiggling his fingers, “come dance!”

Suna gives him a deadpan look. “You’ve got to be joking.”

“Nope!” He wiggles his fingers more aggressively.

With a sigh, Suna sets his glass down and snatches Atsumu’s hands. “Fine. Just stop with the damn fingers.”

Atsumu pulls him to where others are already dancing. A new song is just starting, and when they hear the Spanish guitar, looks are exchanged. Looks like they’re doing this. Taking their positions, the dance starts. Too many times playing Just Dance have led to this moment. How else would they have the entire dance to Despacito memorized?

He and Suna are completely in sync as they swipe their arms over their heads. Then they reach out, grabbing at the air, and shimmy. There are a few people spectating what Osamu would surely call an embarrassment. Komori is off to the side with his phone pulled out, no doubt recording. However, when the chorus hits, Suna slides behind him and slightly out with a hand on his hip. Shaking their hips in a slow-motion with the beat, they then cha-cha adjacent to each other.

Joining hands between them, the other clutches at their chest. Smiling at each other and stepping side to side, then they break apart. They snap their hips, really getting into it. Atsumu would also like to acknowledge how difficult it is to do body rolls in a corset, but he manages. If the feeling of his alpha’s eyes on him says anything, it’s that the moves are appreciated.

Knowing he has Kiyoomi’s attention, Atsumu doubles his efforts. He pointedly shakes his hips and moves his arms fluidly. His body rolls are accentuated with small pelvic thrusts, and he bares his throat. There’s nothing like dancing with his best friend and all the while seducing his boyfriend at the same time.

When they strike their finishing pose, Atsumu rests his forehead on Suna’s shoulder and dissolves into laughter. Suna follows soon after. They must look a sight, but they’re having fun. Suna definitely looks a lot better than earlier. Mission accomplished.

“Is it alright if I steal Atsumu from you now?” Atsumu glances up at the sound of Kiyoomi’s voice.

“Yeah.” Suna steps back and turns to face him. “Thanks for the dance, ‘Tsumu. I’m going to go get that video from Komori.”

“No problem. Send me a copy!”

Kiyoomi easily slips into Atsumu’s space, hooking an arm around his waist and pulling him flush to his chest. Throwing his arms over Kiyoomi’s shoulders, Atsumu raises his head slightly to look him in the eyes.

“Like what ya saw, Omi-Omi?”

“You know I did. You were teasing me.”

“Only a little.” He smirks, looking up through his eyelashes.

As they sway to the music, Kiyoomi leans in, his lips touching the shell of Atsumu’s ear. “Were you showing off for me, baby?”

A small whine escapes him and a shiver runs down his spine. That deep voice makes Atsumu a bit weak-kneed. “I wanted to look good for ya.”

The grip around his waist tightens, and he feels a low rumble in Kiyoomi’s chest. “You always look good.”

God. Can they leave yet? Have they been here an acceptable amount of time? Because Atsumu really wants to go back to their hotel room.

“Omi…”

Kiyoomi shares the sentiment and checks the time. “I think we’ve paid our dues. You ready?”

Atsumu nods and shifts in Kiyoomi’s hold so an arm is left around his waist. It makes it easy for his alpha to swiftly pull him along and out of the ballroom.

When they reach their room, Kiyoomi cradles Atsumu’s face and kisses him thoroughly. It’s slow and sensual, allowing him to taste every bit Atsumu has to offer.

“I’ve wanted to do that all night,” he says between kisses. “Do you know how many alphas were watching you?”

“I don’t care as long as yer watchin’ me. Yer my alpha.”

Kiyoomi lets out a pleased growl. “That’s right. You’re my omega.”

“C’mon, Omi. Show me.”

He kisses Atsumu once more before turning him around. As he unlaces the corset vest, he mouths at Atsumu’s neck, lingering on the most sensitive areas. Kiyoomi's nimble fingers are able to rid Atsumu of his corset and button-down with relative ease.

Laying Atsumu down on the bed, Kiyoomi looks down at him with pure adoration in his eyes and strokes his cheek. “I love you.”

Atsumu reaches up to cover Kiyoomi’s hand with his own. “I love ya too, Omi.”

As the night goes on, he’s continually reminded of the love Kiyoomi proclaims for him. With every embrace and gentle kiss, it’s branded into his soul. And with every sigh of his alpha’s name, Atsumu falls a bit deeper; though, he welcomes the descent if what awaits him comes in the form of Sakusa Kiyoomi.

Chapter Text

When Atsumu and Kiyoomi are in the hotel lobby on their way out, he’s stopped by the tentative call of his name. It’s not a voice he recognizes, though when he turns, he thinks the man looks somewhat familiar. He’s short and has long black hair with blonde tips tied up, and Atsumu identifies him as a beta.

“I’m glad I caught you before you left,” he says. “My name is Kozume Kenma, CEO of Bouncing Ball Corp. You’re a friend of Shouyou’s, and I might have a sponsorship opportunity for you if you’re interested.”

That name rings a bell. He’s the guy who sponsored Hinata’s time in Brazil.

“What kinda sponsorship?”

“It’s for an omega clothing line we’re launching. You and Shouyou would do a few photoshoots together.”

Well, that doesn’t sound too bad at all. In fact, it sounds like a great deal. He had a few offers last night, but they were… not ideal. Since coming out as an omega he’s lost some sponsors, so this opportunity is welcome.

“That sounds great, actually.”

“Here’s my card. We’ll be in touch,” he says before meandering away.

Atsumu flips the card over in his hand. Fancy. He can feel Kiyoomi looming over his shoulder and passes the card over so he can read it. His presence lightens and hands the card back when he’s appeased.

“So what do ya think, Omi?”

“It’s a good opportunity to highlight your omega status. If that’s what you want, you know I’ll support you.”

Beaming, Atsumu hugs Kiyoomi’s arm and leans into the hand that caresses his cheek. Yeah, he’d really like to show the world that he can sport omega clothes even if he is an atypical omega. Though at the end of the day, he has Kiyoomi here with him, so maybe the world can shove it.

Now that the season is over, everything is more relaxed. He still keeps up a workout schedule, of course, but if his diet isn’t exactly up to standards, no one needs to know. He’s been craving fucking everything lately.

“It’s probably because your heat’s coming up,” Suna says as Atsumu purchases some takoyaki from a street vendor.

Since the banquet, Suna stays in Osaka all the time. He’s practically living with Osamu right now. However, Osamu still has a day job, so Atsumu is left to entertain Suna when he gets bored. Hence why they’re out in the wilds of the shopping district.

“Don’t say the H-word. I’m already freakin’ out enough.”

“You’ve been preparing for it, right?”

Atsumu stuffs a takoyaki into his mouth and narrows his eyes. Of course, he’s been preparing for it. His instincts go rabid if he doesn’t build a nest. At least he’s aware of it this time. It’s close; Atsumu knows that. And he swears if he goes into heat while he’s out shopping with Suna again he’ll kill him.

Suna raises his hands in mock surrender. “Yeesh. I’m just trying to look out for you.”

“I know.”

“You’re going to be spending this with Sakusa, right?” He wiggles his eyebrows, making Atsumu roll his eyes, but he nods. “Are you guys going to use condoms?”

Atsumu chokes on his food. Suna stares at him, waiting for the hacking to stop. “Jesus. I mean, I have some. But I dunno how this heat haze is gonna be. I’m on birth control anyway. It’ll be fine.”

While Atsumu says that, there’s always that small worry in the back of his mind. However, the fact that he already has so many factors at play against him getting pregnant makes it even less of a possibility.

“What about your mating glands? Are you covering them?”

Atsumu rubs at one on the crook of his neck. Should he? Kiyoomi wouldn’t bond him; they haven’t talked about that yet. However, a few conversations about Kiyoomi’s inner alpha being aggressive makes him wonder how he’ll react when Atsumu’s in heat. Kiyoomi has never been with an omega during their heat before, well, properly. Atsumu’s first one doesn’t really count.

“I trust Omi… But do ya think I should?”

“I think you should buy a heat collar or sealing patches just to have as an option. I know you trust him, but if he gets thrown into a rut he’s not prepared for, it can be dangerous. It happened to a friend. Now he only lets betas help him with his heats.”

Atsumu raises an eyebrow, picking up on what Suna is insinuating. “Ya helped an omega through a heat?”

“Yep. I thought my dick was going to fall off by the end of it.” Atsumu wants to ask, but at the same time, he knows Suna will go into very explicit details that he doesn’t want to know.

“Well, since we’re out, might as well pick somethin’ up.”

Atsumu has sealing patches in one hand and a heat collar in the other. He’s not sure which one to get. Honestly, this is something he probably should have researched or asked Dr. Yoshiba about. Hinata hasn’t ever talked about them either. Does he not use them then?

The collar is more expensive, but it’s also supposedly more comfortable than the patches. At least, that’s what the box says. This is dumb. Fuck it. He’ll just buy both. Maybe Kiyoomi will have an opinion. Atsumu just hopes that he isn’t offended.

“Is that everything you need?” Suna asks.

“I think so.”

They’re on their way to the front when something catches Atsumu’s eye. He stops and stares. Suna walks backward to where Atsumu stopped.

“Seriously?”

“Sunarin, look at it though! It looks so soft!”

“That’s just the preheat talking and marketing schemes. Let’s go,” Suna says and grabs Atsumu’s forearm to try and haul him away from the aisle of omega nesting materials.

“Rin!” he whines.

“Calm the fuck down. If I can smell you this much, then I know alphas definitely can.” Atsumu does not calm down and continues to whine about his lost conquest through the entire check-out line.

Suna escorts Atsumu back to his apartment before taking off for Onigiri Miya. So now being left to his own devices, Atsumu finds himself padding around his apartment, making sure everything is in place. Damn weird-ass omega instincts. He’s arranged and rearranged his nest numerous times already. Right now, he’s pretty satisfied with how it looks. It’s eons better than the disaster that was his nest last time.

Plopping down on the couch, Atsumu huffs and hangs his head back. He’s still nervous that this heat is going to be like his first one, and it honestly scares him shitless. However, Dr. Yoshiba had seemed pretty confident that this should be a “normal” heat. Whatever the fuck that means.

At least he won’t be missing any volleyball. Small mercies. The longer he sits there, the more restless he becomes. What's he supposed to do? Sit here and just… wait for this damn heat to hit?

Letting out a pathetic whine, he drags himself to his bedroom and dives into his nest. He wants his Omi-Omi. Tugging on one of the loose shirts, he pulls it to his face. It’s one of Kiyoomi’s that he stole. With a smile, he exchanges his own shirt for the oversized one belonging to his alpha. The scent of sandalwood comforts him, and Atsumu is able to fall into a light slumber.

He awakens to the sound of the front door opening and perks up. It can only be one of two people, and he’s pretty sure it’s not Osamu. His skin is damp with slight perspiration, and Atsumu knows the time is almost here. Prying himself from the comfort of his nest, he makes his way to where his Omi is.

Kiyoomi turns from unpacking groceries when Atsumu waddles into the kitchen. As soon as he spots Atsumu he opens his arms for his omega to tuck himself into them. Wrapping his arms around Kiyoomi’s chest, he nuzzles against the crook of his neck and hums in contentment. Kiyoomi hugs him close and presses a kiss to his temple.

“How are you feeling, baby?”

“Just a little warm.” Atsumu lets Kiyoomi turn back to his task but remains clinging to his back, laying his head against his shoulder.

“Did you get anything while you were out with Suna?”

Atsumu stiffens slightly at the thought of the bag in his room. Omi won’t be mad, right? “Umm. Actually, I did.”

Sensing Atsumu’s anxiety, he turns once again to face him. Kiyoomi brushes away blonde bangs from his sweaty forehead. “What’s wrong?”

If this goes badly, he can totally blame it all of Suna, right? Right. “I bought sealing patches and a heat collar…”

“Oh? That’s honestly a good idea. I’m not sure why I didn’t think about that.” He strokes Atsumu’s hair, eyes contemplative. “I can take an extra dose of suppressants too if you’d like.”

“Nah, ya don’t need to do that. It’ll be fine.”

“Alright, if you’re sure.” Kiyoomi presses his face into Atsumu’s neck and licks at the scent gland, making him whine and his knees tremble. “God, you already smell so good. Why don’t you go take a cool shower while I finish in here.”

They both reluctantly pull away so Atsumu can do as requested. He secretly suspects that it’s to get any lingering trances of Suna’s scent off of him, but a cool shower does sound nice. However, with each step he takes towards the bathroom, the louder his inner omega screams at him to return to his alpha.

Looking in the mirror, Atsumu sees how flushed he is. Pink cheeks, irises like liquid gold, a bead of sweat trailing down his forehead—he’s the perfect image of an omega in preheat. Leaning his head back, he can see his swollen scent and mating glands. Curious, he gently rubs one with two fingers.

He groans at the pleasant sensation and relief it brings from the discomfort. Looking at his fingers, they’re oily. The scent glands only get like this during heats and ruts. It makes the scent amplified to attract a mate. Generally, it’s pretty difficult to smell oneself since the body is accustomed to it. However, when Atsumu brings his oil-coated fingers to his nose, the smell is overwhelming.

Atsumu has been told that his scent is jasmine, and that’s definitely true, though it's much stronger than it most likely is on a normal day. However, he also picks up traces of peaches and honey. It’s sweet. He can only imagine what it’ll be like when he’s in full-blown heat. Hopefully, Kiyoomi will like it.

While showering, Atsumu keeps wondering what this is going to be like. Sure, he and Hinata have talked about it, but it’s not the same. He won’t truly understand until he experiences it first-hand. How intense is it going to be? Will it be painful? How will Kiyoomi act?

Feeling himself getting worked up, Atsumu turns the knob for cooler water. It feels nice on his heated skin. How much hotter is he going to get? No wonder people call it heat haze; he feels like his brain might start boiling.

When he gets out of the shower, he dries himself off and only bothers slipping on the t-shirt he was wearing before. It’s just long enough to barely cover his ass, but well, easy access, right?

After throwing his other clothes in the hamper, he picks up the bag with the heat collar and patches. He’s not sure which one to use. Shrugging, he tears open the box of patches and reads the directions on how to apply it. He keeps them on for a whole ten seconds before ripping them off and discarding them. Fuck those. Looks like the collar it is.

The idea is pretty simple but effective. It’s a nude-colored leather collar with a padded inside and a seamless locking mechanism. It’s plenty flexible yet sturdy. Atsumu snaps the collar in place and tugs on it lightly. There’s plenty of breathing room and it’s not aggravating his mating glands, so that’s a start.

Making his way back into the kitchen, he finds Kiyoomi putting prepped food in containers away into the fridge. The sight of his alpha providing and caring for him like this does strange things to his baser instincts. Atsumu feels wetness leak out of him, and he rubs his thighs together, letting out a small whine.

Kiyoomi puts the last one away and locks eyes with Atsumu. His eyes are dilated and his presence suddenly seems to overtake the entire room.

“Atsu, are you wearing anything under that?” He remains pinned under that gaze and shakes his head as Kiyoomi walks towards him. Stopping in front of him, Kiyoomi trails his fingertips up Atsumu’s bare thigh and underneath the shirt’s hem. He groans as he takes a handful of Atsumu’s supple ass. “God, you have no idea what you’re doing to me right now. You aren’t even fully in heat yet.”

Atsumu feels like he’s drunk. Everything is just slightly off-kilter. He rests his arms on Kiyoomi’s shoulders and leans into his chest. The feeling of desire pulses through his head, his inner omega encouraging him to let the strong alpha take care of him. With every breath he takes, the more of that intoxicating sandalwood scent he smells. He wants to bathe in it, devour it.

“Omi…”

“Tell me what you want, baby. I’ll take care of you.”

Atsumu wiggles in his alpha’s grasp at the sound of Kiyoomi’s low voice in his ear. He can feel the slick beginning to run down his thighs and his walls throb, clenching around nothing.

“Ah, I dunno. I just— I feel like I need ya to be inside of me. Right now.”

“As you wish,” Kiyoomi says and lifts him up by the backs of his thighs. Atsumu wraps his legs around Kiyoomi, clinging onto him as he heads towards the bedroom.

Kiyoomi deposits him on the nest and strips out of his clothes. Atsumu watches the muscles of his torso flex with every movement with hazy eyes. If this is how a heat is, it’s not so bad. Atsumu takes off his shirt and tucks it back into the nest, spreading his legs as Kiyoomi crawls between them.

“Wait, shit. Let me get the condoms.”

“Don’t need ‘em,” Atsumu says, watching as Kiyoomi’s dark eyes widen and his nostrils flare. “Too much of a hassle when the heat happens. Plus, I wanna feel ya, Omi.”

“Fuck.”

Kiyoomi practically lunges for him. Their bare torsos slot against each other as Kiyoomi pins Atsumu’s wrists down and mouths at the collar protecting the glands there. He slides his tongue underneath to get just a small taste of their sweetness. Atsumu throws his head back submissively and arches into his alpha, grinding their bare cocks together.

He and Kiyoomi have had sex several times now, but never before has he felt this sensitive. Every touch feels like it’s burning, heating his skin in a delicious, addicting kind of way. Atsumu’s whole chest is flushed. He’s panting, needing what only Kiyoomi can provide.

“I’m going to take such good care of you, Atsu. Whatever you want.” Kiyoomi kisses along Atsumu's jaw before he captures his mouth in a searing kiss.

He releases Atsumu’s wrists in favor of roaming his hands over Atsumu’s body. Atsumu’s hands gravitate to bury themselves in Kiyoomi’s hair. His small whimpers and moans are devoured by Kiyoomi’s insistent kisses and his tongue slipping along his own.

Kiyoomi’s kisses trail down Atsumu’s chest, laving over sensitive nipples. He tries to buck up into the touch, but he’s pinned by Kiyoomi’s body. His abdomen aches dully, further clouding his senses of any thoughts other than Kiyoomi.

“I’m going to fuck you on my knot—pump you full of my cum,” he says between kisses and nibbles on Atsumu’s hip. “Is that what you want?”

“Omi— Omi, please.”

A single finger skims over Atsumu’s entrance and through the obscene amount of slick leaking out of him. “You’re so wet for me.” Kiyoomi brings the finger to his mouth and sucks the slick off of it. “God, you taste so good,” he groans.

“Kiyoomi!”

Kiyoomi’s eyes snap up to meet Atsumu’s teary ones. He looks slightly guilty. “Sorry, baby.” He surges up to plant a kiss on Atsumu's lips. “Your alpha will take care of you now.”

He pushes Atsumu’s legs further apart and ducks down to get his mouth on him. At the first flick of Kiyoomi’s tongue, Atsumu keens, his hips jerking off the nest. He’s so sensitive. Kiyoomi pins his hips down, laying his forearm over his hips, and licks into him like a man starved.

Atsumu attempts to thrash around, his upper body writhing in pleasure. Needy moans fall from his mouth as he pants and searches for something to ground himself. Gripping onto Kiyoomi's hair, Atsumu presses his hips into him further. The alpha moans, licking into his omega, fucking him with his tongue, and eating up every sound he makes.

“Omi!” he wails. His legs shake as he cages in Kiyoomi’s head and comes, gushing slick into Kiyoomi’s mouth and onto the blankets of the nest.

Kiyoomi doesn’t let up, seeming to be intent on slurping up every bit of slick Atsumu will give him. Yet, it somehow still isn’t enough. Atsumu’s chest heaves, feeling his wet pussy clench around Kiyoomi’s tongue. He weakly pulls on curly hair, whimpering to get his alpha to comply.

Finally, Kiyoomi lifts his head, licking his lips glistening with slick. A low rumble emits from his chest, making Atsumu shiver. Kiyoomi moves to hover over him, eyes like that of a predator. It pins Atsumu in place, and he bares his throat.

“Omi, I need ya,” Atsumu says. His body feels so empty. It’s a strange feeling, but he knows exactly what he needs. He needs his alpha to knot him. “Need yer knot, Alpha.”

Atsumu gasps when Kiyoomi takes his hips in a vice-like grip, angling them up. Then he aligns his cock and sinks into Atsumu’s tight heat, groaning and tightening his hold. Atsumu’s lips part as he feels Kiyoomi’s bare cock sliding against his walls. It’s so much. Almost too much. It’s warm, and Atsumu can feel the vein on the shaft throb, making his walls clench down. He clutches at the bedding, letting the feeling of being full consume him. Fuck condoms. They’re never using condoms again.

“Oh, fuck! Oh my god,” Atsumu moans as Kiyoomi bottoms out.

When Kiyoomi starts to move, Atsumu instinctively wraps his legs around Kiyoomi’s waist, letting his alpha sink into him further. Kiyoomi lets out a low growl as he begins pounding into Atsumu. His hands fly up, scrambling for purchase on Kiyoomi’s shoulders and neck.

“You’re so good for me, Atsu. Such a perfect omega. My perfect omega.” Kiyoomi’s voice is guttural, laced with possessive desire. It makes Atsumu shiver, and if he wasn’t already submitting to this man, he’d be on the floor.

“Omi! Omi— needta come. Need yer knot,” Atsumu sobs, throwing his head back as the head of Kiyoomi’s cock plows into his prostate, dragging over his clitoris.

“I’ve got you, baby. You’re going to come on my knot.” Kiyoomi moves to hover over him, never losing his brutal rhythm. “Look at you. Your pretty little cunt is dripping. You were made to take my cock. No one else will ever see you like this. Only me.”

“O— Omi, please!” Atsumu cries, scratching along Kiyoomi’s shoulder blades. He can feel his core tensing, his walls fluttering. “Alpha, alpha—”

“Come for your alpha, Omega,” Kiyoomi says as his knot swells, releasing inside Atsumu. He bites down on Atsumu’s shoulder, sharp canines leaving their mark.

Atsumu comes with a keen, back arching off the bedding. He can feel the copious amount of cum filling his insides. It calms him, sates the raging heat he feels inside.

Kiyoomi wraps his arms around Atsumu and pulls him close, licking into his mouth to kiss him languidly. He cards his fingers through Kiyoomi’s hair and hums into his mouth, content. Kiyoomi places lingering kisses on Atsumu’s cheek, jaw, temple—making him purr. He loves this man.

“How do you feel?” Kiyoomi asks.

“Good.” He opens his eyes and the haziness around his sight has cleared slightly. Kiyoomi is looking at him fondly. “Ya should talk to me like that in bed more often. It was hot.”

Kiyoomi groans and buries his face in Atsumu’s shoulder. “I’m glad you think so. I was trying to keep my alpha in check.”

“What if I don’t want ya to?”

Kiyoomi raises his head with a quirked eyebrow and smirks. “I’m not sure you can handle that.”

“Hmph.”

After a while, Kiyoomi’s knot goes down enough for him to pull out. Atsumu feels a mix of slick and cum run out of him and down his thighs. He can’t decide if it’s hot or gross. Maybe both.

“Let’s clean up before it comes back in full force.”

Atsumu groans and curls onto his side. ‘But I don’t wanna. I’m comfy here.”

“Come on, don’t be a brat. You should eat something too. You need protein.”

His next groan is cut off when he’s manhandled over Kiyoomi’s shoulder, and he yelps in surprise. “Omi~ are ya at least gonna fuck me in the shower?”

Kiyoomi hums and wiggles a finger into Atsumu’s still wet and leaking pussy, punching a moan out of him. “Don’t tempt me.”

Atsumu tempts him.

Kiyoomi fucks him against the shower wall with one of Atsumu’s legs hooked over his arm. He sucks and bites along Atsumu’s collarbones and shoulders until they’re littered with blooming reds and purples. Bends Atsumu over the kitchen counter and knots him, sitting Atsumu on his lap with them locked together, and feeds him like the spoiled omega he is.

Atsumu leans back into Kiyoomi’s chest. He decides this whole heat thing isn’t so bad. Really, he should have known better than to think that. There’s a reason omegas complain about their heats. It’s the next day that it really hits.

When Atsumu wakes, he’s drenched in sweat, his body flushed. The nest is soaked with slick that’s still gushing from Atsumu’s vagina. His cock is hard and the head is an angry red, begging for release. Atsumu pants trying to cool and orient himself. The heat haze is back, and he feels woozy again. He groans at the ache in his abdomen. It’s not near as painful as what he experienced during his first heat, but it’s definitely not what he’d call pleasant.

Rolling over, Atsumu noses at his alpha who continues to sleep like the dead next to him. “Omi, wake up. I need ya.” He shakes his boyfriend, attempting to wake him.

Atsumu flops on top of him and whines pathetically. How is he still sleeping when his omega is in need?! Atsumu’s hard cock brushes against Kiyoomi’s side and the light friction makes his pussy throb.

His inner omega demands his alpha’s attention. So Atsumu bites him—right on his mating gland.

The result is instantaneous. Kiyoomi jolts into a sitting position, his eyes blown wide. “Atsumu, what—” He stops mid-sentence when he sees Atsumu presenting for him.

“Alpha, I need ya. Omi, please.” He looks back at him with teary eyes and his cheek pressed to the sheets.

“Fuck!” Kiyoomi is on him quickly, grabbing Atsumu’s hips and starts pressing his cock inside. Atsumu wails, spasming around him. “God, you’re still so tight, gripping onto my cock so perfectly.” He sucks bruises down Atsumu’s spine as he sits completely sheathed inside him.

Atsumu quivers in his hold, clenching around the huge cock inside him. “Omi— Alpha! I need— fuck me!”

Kiyoomi lets out a snarl as his hands slide up to wrap around Atsumu’s tiny omegan waist and squeezes the soft flesh beneath his fingertips. The slide of Kiyoomi’s cock pulling almost all the way out is so good from this angle, and it surprises him when he’s slammed into with enough force that he’s pushed up the bed. The shock sends Atsumu spiraling into his first orgasm of the day. Then Kiyoomi begins plowing into him.

Atsumu cries out as he’s impaled on his alpha’s cock over and over again. His arms have completely given out and his ass is in the air. His legs shake with effort to keep himself up, and it’s only Kiyoomi’s tight hold that keeps him in place. The obscene amount of slick sliding down Atsumu and Kiyoomi’s thighs squelches between them.

Atsumu pants with his tongue lolling out of his mouth as Kiyoomi thrusts into him roughly. The sound of wet skin slapping together mixes in the room with Atsumu’s chorus of ahs and alphas.

When Kiyoomi moves to completely cover his body, Atsumu collapses into the nest, letting himself be fucked into the mattress. The heady scent of sandalwood surrounds him, and Atsumu can’t think. His brain is consumed only with alpha, Omi, so good, more. His walls spasm, and he comes again, hard.

Kiyoomi growls next to Atsumu’s ear, and he keens, tilting his head to the side. He grabs at Atsumu’s shoulders, pushing him down, and nips at the collar.

Atsumu knows he’s not completely in his right mind at the moment, but he wants it. God, he wants it. He wants Kiyoomi to plunge his teeth into his mating gland—all three of them—and bind them together for life. He wants Kiyoomi to fill him with his seed and—

“Mine. You’re mine. My omega,” Kiyoomi chants as his thrusts speed up erratically.

Atsumu can feel the knot inside him growing, its size pressing against his walls perfectly. When Kiyoomi shoves his knot into him for a final time, releasing inside with a feral growl, Atsumu opens his mouth in a silent scream. Kiyoomi clamps down on the heat collar right on the nape of Atsumu’s neck.

He lays there, completely boneless, heaving. His mind is completely blank until he feels warm breath on his… bare neck. He brings a hand up to tug at the collar and comes away with it in his hand. Holy fuck.

“Shit.” Kiyoomi’s voice is rough. Probably from all that growling.

Atsumu turns his head to look at his boyfriend. “Omi, didja bite through the fuckin’ collar?”

“It appears so.”

“Fuck that’s hot.” At that Atsumu feels Kiyoomi’s cock twitch inside him and release more cum. Kiyoomi maneuvers them onto their sides and wraps an arm around Atsumu’s waist. “What’re we gonna do now though?”

“I won’t bond you. I’ll keep myself more in check.”

“But what if—”

Kiyoomi shushes him. “Don’t. We’ll talk about that after your heat is over.” He leans in to place a lingering kiss on the gland at the side of Atsumu’s neck, making him shiver and whimper in delight. “I’ll take care of you until then.”

For the rest of Atsumu’s heat, it continues that way. He loses count of how many times Kiyoomi knots him. The feeling of Kiyoomi’s cock is engraved in him, yet Atsumu still craves more. He’ll never get enough of Kiyoomi.

Atsumu always knew he could trust Kiyoomi, but it really shows in the way he takes care of him. Cleaning him, feeding him, fucking him, loving him… And through every wave of heat, Kiyoomi gives him exactly what he needs. Even with his mating glands bare and unprotected, Kiyoomi never defects. He kisses them, licks them, and sucks on them, but not once does he appear to even look like he’s going to bite them.

On what Atsumu thinks is the fifth day, he’s much more clear-headed, and the feeling of heat is dwindling. It’s much more manageable and dare he say… enjoyable.

“I love you so much, Atsu,” he says kissing and mouthing at Atsumu’s neck as he gently thrusts into him.

Atsumu sighs and squeezes the hand with their fingers laced together. “I love ya too, Omi.”

They spend the day like that, with slow touches and lingering kisses. And when night settles in, Atsumu curls into Kiyoomi’s side and lays his head on his chest. There’s no other place he feels so safe. He’s really hoping that this talk of bonding will be sooner rather than later. He’s sure that this is the future that he wants.

Chapter Text

“Atsumu-san!” Hinata greets when Atsumu walks into the studio.

Today is the day that they’re modeling the new omega clothing line that Kenma talked about at the banquet. He contacted Atsumu as promised, and now, here he is. It’s been a few weeks since his heat, so thankfully his skin is free of bruises and bite marks. Atsumu had to be very strict with Kiyoomi about not leaving marks before the shoot. He wasn’t overly happy about that, but Atsumu will make it up to him. However, the same cannot be said for Hinata Shouyou.

“Jesus Christ, Shouyou-kun! Were ya mauled by an animal?!” Hinata’s entire neck looks like it has teeth marks embedded into it. In fact… “Holy shit, ya and Tobio-kun bonded already?” Hinata beams at him, nodding as he bounds over to show off his fresh mating marks.

“Yep! My heat just finished a few days ago, and we decided, why wait?” Atsumu raises his eyebrows, feeling that there’s more to the story. “And uh… Tobio’s last rut was three years ago… We weren’t expecting it to hit him that hard though!”

Atsumu just stares at Hinata. Idiots. Both of them. Hinata is lucky he didn’t get injured.

Rutting alphas can be dangerous, especially if they aren’t keeping a set schedule for their ruts. Alphas are weird. Their rut cycle isn’t like an omega’s heat cycle at all. Ruts happen naturally one or two times a year depending on the alpha, though they can definitely be influenced by other outside factors.

During pre-rut, alphas will claim a den and mark it with their scent to lure in a mate and deter other alphas. In modern times, a den is just where they live or a place they feel comfortable with their sleeping space the most heavily scented. If they have a mate or partner with them, this will bring the alpha’s rut to fruition faster than if they are alone. Omegas can produce a special pheromone to do this.

A sudden flood of alpha hormones is what causes a rut. It’s similar to an adrenaline rush. It’s one of the reasons rutting alphas can be so dangerous. When alphas are thrown into a rut due to situational circumstances, it can become a problem. Activating that fight or flight response usually means fight, and during a rut, alphas are strong. It’s due to that surge of hormones. Skipping the pre-rut phase makes the sudden onslaught all the more serious.

Ruts aren’t only for mating purposes, which is why hostile situations can evoke them. In the early days of civilization, an alpha’s rut would be triggered with the need to protect. Older alphas are typically better at controlling their inner alphas, but when they can’t, that’s when it’s a feral situation.

Atsumu remembers when Osamu’s first rut sprang up out of nowhere. He remembers Osamu’s deep clove scent being stronger than normal. When he opened their bedroom door, Osamu had slammed him against the wall, snarling in his face. If he hadn’t recognized Atsumu as family, he thoroughly believes he would not have come out of that encounter unscathed.

“Okay, I know what you’re thinking, but it’s fine! I’ll make sure he ruts every year from now on! Enough about me. How was your heat this time?”

“Right… It was good. Real good.” Atsumu’s grin grows as he remembers every detail. “Shouyou-kun, Omi bit through my heat collar!”

“He what?!” Hinata’s eyes bulge. “Holy shit, Omi-san.”

“It was fuckin’ hot.”

“And he didn’t bond you after a display like that?”

“Nope. I trust my Omi-Omi,” Atsumu says proudly.

“Wow. You do wanna bond though, don’t you?”

“Yeah. We actually talked about it, and Omi is gonna delay his rut until my next heat.”

Hinata claps his hand in small pats in front of his chest. “Oh, that’s exciting!”

It really is, isn’t it? Atsumu is taking a step in life that he never thought would happen. He’s going to bond, be mated. Someone really wants to be with him for the rest of their lives. To think that, that someone is Sakusa Kiyoomi is like it’s straight out of a dream. The craziest thing is that he actually wants this. Who would have thought?

When Atsumu had told Osamu about their plans for the future, he’d been nervous. Would Osamu think it’s too soon? Would he be against it? However, Osamu just smiled and said that he’s happy for him.

Atsumu knows that Osamu ideally would like to bond with Suna, but that’s not possible. At least for traditional methods, it’s not. Betas don’t have mating glands like omegas and alphas do, nor do they produce the proteins in their saliva that creates the bond when the skin is broken. That’s why betas typically show their bonds through marriage. However, a relationship like Suna’s and Osamu’s is… frowned upon.

It’s not fair. They aren’t hurting anyone. Besides, their relationship shouldn’t matter to other people. That’s why it’s their relationship. A male alpha and beta should be able to hold hands in the streets without being ridiculed. Atsumu will fight anyone that dares talk shit about his brother or best friend.

“Kenma!” Hinata zooms past Atsumu. He’s surprised that Kenma is actually here. Making his way over, he can see Kenma with a sly grin on his face, examining Hinata’s neck.

“We can work with this actually. Those teeth marks on your throat are going to need to be covered though. Hello, Atsumu,” Kenma says.

“Hello. Work with what exactly?”

“Since we’re trying to appeal to omegas in general, it’s good to show a representation of both mated and unmated status.”

Atsumu supposes that makes sense. Omegas are still a minority in sports. Mated omegas are even rarer. Maybe showing that sports brands support all omegas in continuing a professional sports career even after bonding will help. At least that’s probably the aim.

“Do ya come to all yer company’s promotions?” Atsumu asks as they are shown a few of the samples.

“I’m only here because Shouyou is.”

Kageyama has been standing awkwardly at the back of the room since Atsumu arrived. His eyes never leave Hinata. It’s a little unsettling, but Hinata revels in it and sends him cute little waves. Atsumu supposes that it’s because of their freshly mated status. Kiyoomi might be here too if he didn’t get called to Tokyo. Akira needed his help moving some furniture. Atsumu thinks it’s just an excise to get Kiyoomi to Tokyo.

Atsumu wishes he could have gone. He hasn’t seen Akira since the holidays. Although they do keep in contact through text, it’s not exactly the same. Atsumu doesn’t want to be selfish though, so he sent Kiyoomi on his way yesterday with a gift for his family and a kiss.

After the small tour of the set, he and Hinata are taken into the dressing room to get ready. Atsumu has modeled a few times before, however, it was for alpha marketed brands. Whoops. Oh well. As an omega, he can already tell a difference. The stylists aren’t stiff or flittering around, and the makeup artists are less hesitant to put more than just foundation and powder on him. Atsumu has on a full face of makeup. Will he ever actually wear eyeliner while he works out? Probably not, but hey, it’s making his eyes pop.

They model a variety of different outfits. Atsumu likes the compression set and will probably buy some when they become available. They’re comfortable, and he still looks good. However, he has to admit that the yoga pants make his ass look great. That’s definitely what’s important, right? Hinata favors the crop top that he has on. The way that it highlights his lean abs on his smaller frame is definitely eye-catching.

Thankfully, everything here goes well. The outfits are comfortable, the staff is pleasant, and nothing is overly demanding. The atmosphere is completely different than anything he’s modeled for before. All in all, it’s a good experience, and Atsumu would definitely do it again. He just hopes that the final images look good. Honestly, he’d be lying if he said he wasn’t a little nervous. This is going to really be putting himself out there… as an omega.

Atsumu and Hinata are casually chatting about the shoot as they head back into the dressing room. Kenma offered to treat them both to dinner, so they’re pretty pumped about it.

Once he’s showered and dressed, Atsumu checks his phone for any messages and is alarmed at the number of notifications he has. What he finds most concerning is the number he has from Komori of all people. What the hell happened? Disregarding the missed calls, for now, he opens his messaging app.

Motoya
Atsumu I’m so sorry! I didn’t think this would happen! It didn’t even cross my mind!
Where are you? Are you okay?
Suna is freaking out!
Okay that’s a strong word for Suna but he is... not calm?
Kiyo is anxious and I don’t know what to do.
Are you still at your photoshoot?
Please text me when you’re done and before you go anywhere!

Sunarin
Shit is really hitting the fan right now. Check the gossip columns online
These fuckers only care because of your status change
Stay at the studio. I’m coming to get you

‘Samu
‘Tsumu stay inside ya hear me? It’ll be fine. We’ll handle this together like we always do.
I’m stuck at the shop. Rin is coming to get ya. I’ll meet ya both back at my place

Omi <3
Atsu are you okay? I tried calling but I’m sure you’re still at the shoot.
Motoya is a basket case. I know he didn’t think this would happen. Hell, no one did.
I’m getting ready to drive back to Osaka.
Call me, please. I love you.

What the actual fuck?

Following Suna’s advice, he begins pulling up the gossip columns. There he finds what he’s looking for rather quickly. Oh. Well, this isn’t good.

A Long-Awaited Love?

V. League Division 1 players Suna Rintarou and Miya Atsumu were seen dancing rather intimately in a video posted by Suna’s teammate Komori Motoya. The video was reportedly taken at the End of the Season Volleyball Banquet held just last month.

This isn’t the first time the two have been seen in precarious situations together either. Back in December, Miya was seen being carried by Suna as he went into heat. Other eyewitnesses state that the two are often seen together in Osaka’s shopping district. Suna is also found at Onigiri Miya, the restaurant owned by Miya Atsumu’s twin brother on numerous occasions.

Ever since Miya’s shocking reveal of being an omega last October, we’ve kept a close eye on Japan’s most unlikely omega. While some criticize the League’s handling of the situation, others applaud Miya’s impact on the industry.

It’s no secret that Suna and Miya have a history. They are high school teammates and close friends. However, it’s speculated that Suna has always been aware of Miya’s omega status and has long been his secret lover.

It appears that omega Miya Atsumu was never on the market in the first place. He’s been claimed, and by a beta no less! Neither player has yet to confirm or deny these claims, but it doesn’t seem like there’s much to deny. Take a look at the original video yourself if you have any doubts about their unbridled love. [Link]

Dear god. What is this shit? And unlikely omega? What the fuck is that supposed to mean?

Atsumu and Kiyoomi had decided to not go public with their relationship to maintain privacy. They haven’t been exactly hiding it though. Hell, Atsumu wears his bracelet every day. Though it’s often covered by his coat…

The logical thing to do here is to just tell the truth, right? It’s an easy fix. He’s being courted by Sakusa Kiyoomi and Suna Rintaou is just a friend, more like a brother, really. God, but then what if they spin some bullshit narrative about Atsumu two-timing them. Though that doesn’t really explain why everyone is so bent out of shape over this. It’s not… that bad, is it?

“Uh, Atsumu-san?” He startles at Hinata’s voice, having forgotten where he was for a moment. Looking up, Hinata’s lips pull down in worry. It seems he’s seen the news as well.

“It’ll be fine, Shouyou-kun! Omi-Omi and I will just go public with our relationship.” Atsumu plasters on a smile, trying to feel that false optimism.

“That’s right! Don’t let all those stupid people’s comments bother you!”

“What comments?”

Hinata’s eyes bug, and he waves his hands in front of himself. “Nothing! No comments! Just the dumb gossip column!”

A pit of dread settles in Atsumu’s stomach. He knows that he shouldn’t look. He knows it’s not going to be anything good or pleasant. Atsumu just can’t help himself though. Even as Hinata continues to warn him and try to physically take his phone away, Atsumu can’t stop himself from tapping View Comments.

rustymuffin16
Wow I can’t believe Suna would settle for an omega like that.

OrdinaryAlpaca
Well he’s just a beta any omega is better than no omega

pleasesendmefood
Damn what a lucky bastard

iluvmymum69
I thought he and Sakusa had a thing

chumbucketfan
Thank god they don’t

omideservesbetter
Why would an alpha like Sakusa want an omega like that anyway?

shiro_nagi888
Right? Miya has a nice face but his body is so big. Not very omega like.

gojos_smelly_socks
I don’t know. I’d still fuck him

astumu_stfu
Miya probably couldn’t get an alpha if he tried. Do you see the way he acts?

kiku_chaaaan679
Not a proper omega at all

sk_749302
He just needs a real alpha to put him in his place. Suna won’t be able to handle him.

Mtndewforever
I’m still skeptical on if he’s actually an omega or not

Basementbbsmatter
Of course he is! He has a medical condition!

atsumus_dead_toenail
He probably can’t even carry pups. What a waste

atsumusthighs
Oh to be crushed by his thighs while eating his pussy gushing slick.

chokemeatsumu
Well I’m happy for them!

masa1253_ougi
Imagine being so desperate that you fuck an omega with an alpha’s body

It’s endless. The barrage of words imprint on the backs of his eyelids, and Atsumu can hear them ringing in his ears. This isn’t new. It can’t be. The others had to know people were saying shit like this about him online. Their reactions are proof enough. Now is just the first time that Atsumu is going to have to deal with it because of this stupid rumor.

Atsumu has never been interested in gossip magazines. He gets the dirt right from the source. Hearing about Gao trying to court Hoshiumi is much more entertaining than reading about Ushijima supposedly dating some model because it’s obviously not true. Said model is Haiba Alisa who is actually dating the Hornets’ setter, and Ushijima has said that his omega is currently in France.

Before coming out as an omega, Atsumu didn’t care what people said. Playboy alpha, eligible bachelor, seen shacking up with Hinata Shouto. It didn’t matter. Atsumu knew none of it was true. However, this? Maybe this is true.

Maybe Kiyoomi will realize he’s making a huge mistake. Atsumu isn’t a proper omega, he’s big, he’s not omega-like, he doesn’t know if he can carry pups. Atsumu can feel himself spiraling. Kiyoomi deserves better. Kiyoomi wouldn’t settle for an omega like him. Kiyoomi could have any omega he wants.

“—umu-san!” Citrus.

“Hey, Atsu— -an y– — me?” Patchouli. Remnants of clove.

Atsumu regains his surroundings with his face tucked into the crook of Suna’s neck and basically leaning his entire weight on him. It’s a comforting, familiar place. Wrapping his arms around Suna’s neck, Atsumu tries to calm down. He feels like if he tries to speak he’ll completely lose it.

“Oh thank god,” Suna says, pressing a hand gently to the back of Atsumu’s head. “I thought you were dropping.”

“I called you a car.” He hears Kenma say. “It’ll take you wherever you want to go. We’ll have to get dinner another time, Shouyou.”

“Thanks, Kenma. I’ll hold you to that!”

Suna nudges Atsumu’s side. “Can you walk yourself, or are you going to stay like that?” Atsumu grunts in answer. Sighing, Suna hauls him into a bridal carry. “Alright. Come on you big baby.”

“Lead the way, Tobio! Be a big bad alpha and keep everyone away from Atsumu-san!”

Somewhere in Atsumu’s mind, he wonders if sending Suna to retrieve him was a good idea. It’ll only feed the rumors. What about Osamu? How is he handling this?

The lighting shifts and Atsumu squeezes his eyes shut. With that comes the voices of several unfamiliar people. They drone in his ears, fading in and out. Atsumu blocks them out as much as he can. He doesn’t want to hear their probing questions and accusations.

He’s placed in a car and he tries to open his eyes, but everything feels so heavy. Atsumu is supposed to call Kiyoomi. He wishes his Omi was here. His Omi-Omi is coming, right?

“Hey, Atsumu, don’t you dare drop on me! You hear me?!”

“I’m so sorry! I thought he already saw! I swear!”

“Shouyou, you need to calm down. You too, Suna-san.”

“Fuck!”

Most of the car ride is a blur. Mainly he remembers the scents of patchouli, orange citrus, and pine mixing together in the backseat. It’s nice.

Then there’s spicy clove and a gasp.

“He keeps trying to drop. I’m not exactly sure if there’s something specific that set him off. Hinata said he didn’t start dissociating until he started reading comments.”

Warmth and something soft wraps around him.

“Hey, ‘Tsumu, stay with me here, ‘kay?”

“Omi…”

“Rin, call Sakusa.” He’s leaning against Osamu who is stroking his hair. He keeps telling Atsumu to stay with him, but he’s right here, isn’t he?

“Atsumu, Kiyoomi wants to talk to you. Just listen, alright?” Atsumu feels Suna sit on his other side, leaning in closer to him.

“Atsu? Baby, can you hear me?” It sounds like Kiyoomi is right in front of him but a bit distorted. “I’m on my way back. I’ll be there in a couple hours, okay?”

“Omi?” Atsumu wiggles, trying to escape from the blanket he’s swaddled in. “Yer comin’ here?”

“Of course. I’m worried about you. Suna said you aren’t doing well. Want to tell me what happened?”

Atsumu thinks about everything that he saw and decides that he doesn’t want Kiyoomi to know. He’s selfish and doesn’t want his alpha to find out how pathetic he is. Kiyoomi can’t leave him. Atsumu can’t lose him.

“‘Tsumu, hey,” Osamu says, rubbing his arm. “Come back to us. Ya don’t gotta say.”

Atsumu manages to worm his way out of Osamu’s hold and stands abruptly. “Bathroom.”

He shuffles his way to the bathroom and locks the door. Bracing himself over the sink, Atsumu examines himself in the mirror. His complexion is pale and his eyes sunken. In plain terms, he looks like shit.

The mirror doesn’t lie, and it shows Atsumu everything that’s wrong with him, highlighting all his flaws. His skin isn’t silky smooth, his hair looks dull and straw-like, his eyes are puffy and tired. But he can fix that! He just needs to do skincare and hair treatments and wear makeup! Yeah! He can be beautiful too, right?

It’s been six months now since he started hormone therapy, and he can tell a difference. It’s like they said, he has a nice face, but he’s so big. No treatment is going to cause him to shrink or narrow his shoulders. And it’s certainly not going to turn him into a proper omega.

What was he thinking? How has he been so ignorant these past few months? How did he manage to let himself believe that he’s a good omega? Or is it that he’s so weak-willed that a few comments undo all of his work? Which is the truth?

Atsumu can be beautiful for Kiyoomi, be good for Kiyoomi, anything for Kiyoomi. He’ll go on a diet and do more cardio training. He’ll be quieter and use the scary eyelash curler.

Then there’s the elephant in the room. Can Atsumu carry pups? He knows Kiyoomi wants kids. Can Atsumu give that to him? He has to, needs to. It’s easy to find out, right? Right.

Sinking down against the door, he pulls out his phone and navigates to his patient portal app to make an appointment to see Dr. Yoshiba. She can give him answers. She has to.

Once he confirms an appointment time, Atsumu’s thumb hovers over the Rakuten app. He could just buy a few new beauty products. It wouldn’t hurt. He never even switched from his old ones. Using products specially made for omegas would be better, right? He doesn’t own any makeup either. A little would be fine…

Atsumu has been reading reviews and comparing products for god knows how long before a knock on the door startles him.

“‘Tsumu, ya’ve been in there for over an hour. Can ya come out so we can talk? …or somethin’?”

Hitting Place Order, Atsumu stands and slowly unlocks the door to rejoin his brother and friend. Right. This affects them too. This isn’t all about him. He can’t keep being selfish about everything.

Osamu appraises him when the door opens. He doesn’t look completely satisfied but leads him out to the living room anyway. Atsumu reclaims his spot between the other two and waits for someone to say something. It’s a good long moment before Osamu finally speaks.

“I know what yer probably thinkin’. Some shit about Sakusa leavin’ ya, right? Anyone that’s seen ya two together knows that’s horseshit. That man would move mountains for ya.”

Atsumu looks to his brother. There’s no lie in his eyes. Osamu fully believes what he’s saying, but doubt still lingers in Atsumu’s mind. Kiyoomi is the perfect alpha; the kind that anyone would hurt themselves, trying to please and gain the attention of.

“But what about what everyone was sayin’? It’s true, ain’t it?”

“Fuck them,” Suna starts. “If there was a shred of truth to this damn article, I wouldn’t be ‘settling’ for an omega like you. I’d be damn lucky that such an amazing omega allowed me to court him.”

Atsumu’s bottom lip wobbles as he tries to keep himself in check. “Sunarin…”

“No, none of your gross tears. Don’t get your snot on me.” A small laugh bubbles from Atsumu’s throat, and he lunges for Suna. “Shit! Get off! You’re heavy!”

Osamu smiles deviously and joins Atsumu in his assault. The three of them end up tussling on the floor with Suna helpless as two Miyas lay across him. Atsumu knows that they’re just trying to distract him and make him feel better, but it’s actually working a bit. They used to tussle like this in high school fairly often. It’ll all come flooding back later when he’s alone, but right now he at least has his little family.

Kiyoomi finds them still draped over Suna’s unmoving body when he lets himself in.

“Atsumu?” Atsumu springs up, pushing off of Suna who lets out a grunt.

“Omi!” He rushes into Kiyoomi’s arms, scenting him in relief. “Yer here.”

“Of course, I am. Where else would I be?” Atsumu just shrugs, trying not to think about it. Not when his Omi is right here.

Osamu and Suna push themselves up to a sitting position. Now that everyone is here, it seems that they need to figure out a game plan. Kiyoomi settles on the couch and guides Atsumu to sit on his lap.

“Rin and I talked, and we think that going public is the best option.” Atsumu is about to agree. He had already thought that he and Kiyoomi going public would be best. However, he quickly shuts his mouth when Osamu continues. “All of us.”

Chapter Text

Atsumu must have heard that wrong. There’s no way that Osamu actually meant all of them. Are he and Suna seriously considering coming out during this whole mess? Of course, he’ll support them. It’s just going to get a lot of attention since Suna is in the spotlight right now. Before this, Atsumu had even kept telling Osamu that he and Suna should come out before it leaks somehow. He definitely never expected a situation like this. Does he mean that they all make a statement together or that he and Kiyoomi should publicly announce their relationship first and let it die down before Suna and Osamu say something?

His thoughts are interrupted by the sound of Osamu’s cell phone ringing.

“It’s Pa,” he says after pulling it from his pocket. News must have reached him in Hong Kong. That was fast. Osamu presses accept and scoots on the floor so he’s in front of Atsumu and Kiyoomi. Suna follows suit as Miya Yoshirou becomes visible on the screen. “Hey, Pa. I’m guessin’ ya saw the news?”

“Yeah, and I’ve been tryin’ to reach Atsumu, but I can’t get a hold of him.”

Atsumu ducks his head down so that he’s in view. “Sorry. I had a photoshoot earlier, and then, well…” Kiyoomi leans in as well so that Yoshirou can see all of them.

“Oh, good. I’m glad all ya kids are together. Are y'all alright?”

“Yeah, we just… gotta figure out how to handle this.”

“Is there anythin’ I can do?” Osamu and Atsumu smile fondly at their father. They know that he’d do anything he can to help them, even all the way in another country. That’s the reason he’s even there. Neither of them had to work part-time in high school because their father completely supported them. Although, it would have been nice to see him more. Hopefully, in the near future, he’ll be able to retire and stay here in Japan.

“Nah, I don’t think so. But thanks for askin’.”

They stay on call for a while longer, explaining their plans to have Atsumu and Kiyoomi address the rumors by publicly announcing their relationship. Then when Suna is inevitably approached, that’s when he and Osamu will announce their own relationship. Honestly, Atsumu thinks they should just drop all of it at once and let them all flounder, but he’ll do this how Osamu and Suna want.

Once they hang up, Osamu heads to the kitchen to start dinner, and Suna trails after him. They’re probably just trying to give Kiyoomi and him some privacy to talk. They probably should. Atsumu relaxes back onto Kiyoomi’s chest, glad that his alpha is here with him. He’s not in the best mental place still, but he’s definitely better than earlier.

It’s hitting him now that he almost dropped. That’s scary to think about. Drops are hard on the body; that’s why the system slows down to help regulate itself. Some people think that omegas are weak for being the only dynamic with drops, but that’s not true. Any dynamic can experience something similar. Omegas are just more susceptible to dropping due to their physiology being more sensitive to the flux of hormones. That’s why it’s extremely rare to hear about someone who isn’t an omega dropping. Then, of course, each dynamic’s drop is different. Either way, dropping is bad news.

Burying his face into Kiyoomi’s neck, Atsumu inhales the scent of sandalwood that he loves so much. Arms tighten around his waist, and he doesn’t know what he’d do if he never felt those arms around him again. He tries to keep from delving into those deprecating thoughts by reminding his stupid brain that Kiyoomi loves him. He wouldn’t have come rushing back from Tokyo otherwise. Kiyoomi is here with Atsumu. That’s all that matters…

“What’s wrong, love?” Kiyoomi asks, stroking Atsumu’s hair. He must have smelled a shift in his pheromones.

“I just fuckin’ hate feelin’ like this.”

“Do you want to talk about it?”

Raising his head up so he can look Kiyoomi in the eye, Atsumu tries to find where to start. He supposes he should just rip off the bandaid. “Are ya really sure ya wanna bond with me?”

“Of course, I am.” Kiyoomi cups Atsumu’s face, ensuring that he won’t look away. “Miya Atsumu, I love you so goddamn much. There is no one else in the world that I would rather be with.”

Atsumu’s lip trembles at his alpha’s words and the sincere look in his eyes. He only wants Kiyoomi to have the very best. He’d do anything for him. The things people said about him are true though. That means he should do better. He can do better.

“Even though what they said about me is true?”

“Fuck them. I love you just the way you are. Everyone else who matters does too. Honestly, they’re probably just jealous because they know they stand no chance in gaining the affections of a beautiful, talented omega like you, Atsu.”

Lowing his voice to a whisper Atsumu asks the question he’s been dreading. “Even if I can’t give ya pups?”

“Even then. We can always adopt. Besides, when we’re ready, I’m not against trying several, several times.” Kiyoomi smirks when Atsumu giggles and pushes him on the shoulder lightly.

“Omi, ya perv.”

“You like it though.” He leans in so his lips touch the shell of Atsumu’s ear. Slipping his hand down from Atsumu’s waist, Kiyoomi gropes his ass. “You have the best ass I’ve ever seen in my life. And here?” His other hand moves to palm at Atsumu’s crotch, making him gasp. “Your pussy always feels so good around me. Nice and tight and dripping wet for me.”

Oh god, what is Kiyoomi doing? Atsumu can feel himself starting to get aroused. Now that Atsumu’s photoshoot is over, Kiyoomi’s pent-up desires to mark and claim are coming out in full force.

“Omi! We are at my brother’s apartment!” he hisses.

“I’m simply expressing how perfect you are.” Kiyoomi leaves a lingering kiss right on Atsumu’s mating gland.

“Hm. Maybe you’ll have to show me when we get home so I completely understand.” The wolfish grin Kiyoomi sends Atsumu tells him that he agrees with that sentiment.

“Are ya done bein’ gross in here?” They turn to see Osamu wrinkling his nose. “Food’s almost done.”

Atsumu leans his head against Kiyoomi’s cheek, chuckling as Osamu walks away. It’ll be okay. Things will all be okay.

They don’t address any of the rumors today. After contacting their PR manager, it’s decided to have Kiyoomi and him make a post from their personal accounts that’s been scripted for them in the following days. If Suna is questioned about the situation even after this, that’s when it’ll get interesting. There are very few people that know about Suna and Osamu’s relationship, and this includes the volleyball circuit. Komori is the only member of EJP privy to the information. Though he’s pretty sure that most people will back them up if needed—the monster generation especially.

That means Atsumu and Kiyoomi are able to relax together for the evening. However, they don’t do all that much relaxing. Their activities definitely keep Atsumu’s mind from thinking about anything other than Kiyoomi. By the end of the night, Atsumu is so exhausted that he passes out as soon as his head hits the pillow.

It’s not until a couple of days later that Atsumu starts thinking about it again. Checking his mail, there’s a package for him. He’s not expecting one until he remembers his impulse online purchases. Alone in his apartment, Atsumu opens the package to find a large assortment of different beauty products. There’s a vague memory of their uses lingering in his mind, and somehow, they’re all different.

Luging everything to the bathroom, he glances at the products then at himself in the mirror. Large golden-brown eyes stare back at him blankly. Atsumu leans in to examine himself, and using a finger, he gently stretches the skin on his face. The pores on his nose look like craters, and have his cheeks always been this rough?

He peels off his clothes and takes a good look at himself. Honestly, he’s lost some of his bulk, though that’s not saying he’s not strong. His muscle has just become more lean and compact. The same cannot be said for his hips and ass. Poking at the thin layer of fat on his hip, he cringes. That didn’t use to be there. Logically, he knows that it’s just from his body’s physiological changes, but mentally, it means he needs to lose weight. When he turns sideways, at least his stomach is flat.

Even with these changes, there’s no denying that he’s big. Kiyoomi has reassured him multiple times that he likes how Atsumu looks, but what if Atsumu doesn’t like how he looks? Being in the public eye, the world is his critic. It’s hard not to get the things they say into his head and take them to heart. When they poke at his most vulnerable insecurities, how can he not waver? He’s just trying not to fall.

There’s only so much he can do, but beauty care is one of them. He and Kiyoomi are going out to dinner tonight, and Atsumu wants to look good for him. Slapping his cheeks with both hands, Atsumu gives his reflection a determined look. Time to get started.

Warm water eases his tense muscles as he washes himself thoroughly with some fancy soap that’s supposed to enhance his natural scent. It’s probably bullshit, but well, he’s trying it anyway. At least his shampoo and hair care have improved since high school, so he doesn’t need to change anything there. Then, he exfoliates with a sugar scrub with tea tree oils or something. He doesn’t know.

Now, he’s supposed to shave. Atsumu has never been an overly hairy guy, but he’s an omega. That means he’s not supposed to have body hair in today’s beauty standards. Looking at the patches of hair on his legs, he supposes that it wouldn’t be too bad to shave it off. The armpit hair should go too. Then there’s the pubic area. He’s always kept it manageable. No one was seeing it anyway. Now he has Kiyoomi though. His alpha has never said anything, but he’d probably like it better shaved, right? One way to find out.

It all takes a lot longer than he thought it would. Maybe he should wax. Once he’s out of the shower, he puts on moisturizer, and well, he actually feels pretty good. Next is more hair products and makeup. People really do all this every day? Good lord.

Atsumu is no makeup pro, but he thinks he did a decent job. He’s given himself a “natural” look. And yes, the eyelash curler is just as scary as it looks, but his eyelashes look so long now. His lips look nice and juicy, and Atsumu would totally kiss himself. So Kiyoomi will definitely approve… Hopefully.

He eyes the pleated skirt that he’s still never worn for a moment before grabbing high-waisted jean shorts instead. He’s not feeling quite that brave today. A flowy blouse tucked at the front completes the look. Atsumu’s first instinct is to go show Kiyoomi, however, he restrains himself and sends a mirror selfie to both Suna and Hinata for feedback.

Hinata
😲 atsumu-san?!?!? 😍😍😍 you look amazing!!!! Like whoa! Do you and omi-san have a date tonight?

Sunarin
Damn 🥵 Osamu says to put on some clothes lmao

He snorts at his friends’ reactions. At least he has their approval. Feeling a burst of confidence, he decides to go see Kiyoomi.

When Kiyoomi opens the door, the first thing he does is rub himself all over Atsumu, scenting him. He pulls Atsumu inside and cages him against the door, nuzzling into Atsumu’s neck. It’s a very rough and thorough scenting that turns Atsumu on much more than it probably should.

“Not that I don’t like this, but what’re ya doin’?”

“You smell so fucking good. I can’t not have my scent on you.” He pulls back, looking at Atsumu with dilated eyes.

“Ya markin’ yer territory?” Atsumu smirks as Kiyoomi gives him a once-over.

“Something like that. Actually, hang on.” Kiyoomi gestures to the couch as he walks towards his bedroom to retrieve something.

Atsumu takes a seat to wait. Smiling to himself, he’s pretty sure Kiyoomi likes it. All the extra work is worth it if he gets a reaction like that every time. He looks up as Kiyoomi returns.

“I was going to wait until dinner to give you this, but I think it’ll go with your outfit. And well, I’d like to see it on you.” Kiyoomi sits down next to him and presents Atsumu with a decent-sized, leatherette box.

Pulling open the top, Atsumu’s eyes widen in surprise. It’s a leather collar with a stunning opal on it. He looks up at Kiyoomi’s face, trying to keep his composure calm.

“Omi?”

“Will you accept this collar from me, Atsumu?”

All Atsumu can do is nod and throw himself at Kiyoomi. He knows they plan to bond, but actually getting a collar makes it more real. It’s more tangible and there’s something to tie them together until the day comes.

“Will ya put it on me, Omi?”

Kiyoomi’s nimble fingers easily clasp the collar into place. It fits perfectly with the opal as a nice weight on his throat. Atsumu leans into the hand caressing his face.

“You’re so beautiful, Atsu. I’ll always think you’re beautiful, no matter what.”

Atsumu leans in to kiss him. The feeling of Kiyoomi’s soft lips on his own is all the love and devotion he could ever need. Kiyoomi is where the sun meets the sea, beautiful and serene with a gentle flow and a touch of warmth. Atsumu loves him more than he ever thought possible. Yet, now he knows how vast the feeling of love truly is.

They wait until the end of their meal to take pictures to post. Atsumu is particularly fond of the one with Kiyoomi kissing his cheek. Each of them makes a separate announcement. Their PR rep gave them a script to follow, but those are more like guidelines.

Omi-Omi presented a collar to me tonight! It's perfect. He's perfect. I'm the luckiest omega in the world. Yes, that means I'm not dating Sunarin. He's my best friend and like my brother. Omi and I have been together for months. We were never hiding it, just didn’t advertise it.

He looks over the message and adds the photo before Tweeting it out into the void. He’d add more, but fuck Twitter and the character limit. No one reads long ass threads of explanations anyway. At the top of his timeline is Kiyoomi’s own post.

It seems some things need to be addressed. I have been courting Atsumu since December. We were never trying to hide it; anyone could clearly see us holding hands in public. Atsumu is beautiful inside and out. He's the love of my life, and I can't wait to become his mate.

Atsumu smiles seeing that Kiyoomi has also gone a little off-script. The words make Atsumu’s heart flutter and when he looks up to meet Kiyoomi’s gaze, he knows that everything will turn out okay. Those dark, emerald eyes hold meaning far deeper than words can convey. Atsumu feels safe in that gaze, treasured. Even if Atsumu falls, Kiyoomi will be right there to catch him. And of course, Atsumu would do the same for him in a heartbeat.

Once back at the complex, they abandon their phones for the night. The outside world can wait. Atsumu rests back on his arms on Kiyoomi’s bed. Dark eyes never stray from Atsumu as Kiyoomi takes his leg in hand and presses lingering kisses up the smooth skin.

“Did you do this for me, baby?”

“Yeah,” Atsumu says, his cheeks flushing slightly. “Do ya like it?”

“I do. Your skin is so soft.” Kiyoomi continues his ministrations, caressing Atsumu’s calf and working his way up his thigh.

“I’ll keep doin’ it for ya then. I’ll do anythin’ for ya.”

“Only if you want to. I’d never ask that of you.”

“I wanna.” Kiyoomi’s fingers slip underneath the denim on his upper leg. Warm breath tickles his skin, making Atsumu’s breathing hitch. “I… did somethin’ else too.”

“What’s that?”

“Yer gonna haveta undress me to find out.”

Raising an eyebrow, Kiyoomi undresses him like he’s delicately unwrapping a present. The look in his eye tells Atsumu everything he needs to know.

Atsumu wakes up the next morning to the very unfortunate sound of his alarm. Groaning, he checks it, not having remembered setting it. His eyes widen and he jumps out of bed, cursing. It’s not an alarm; it’s a reminder message for his doctor’s appointment in an hour. One that he made impulsively on the bathroom floor after nearly dropping.

Kiyoomi groans and peeks one eye open. “Atsu?”

“Sorry, Omi. I forgot about my appointment today. I’ll be back later.” He leans down to plant a kiss on his alpha’s forehead. Kiyoomi gives him a sleepy smile before burrowing himself into Atsumu’s pillow. So cute.

After making himself presentable, Atsumu makes it to his appointment with only minutes to spare. Now he waits for Dr. Yoshiba in an exam room, wondering how this is even going to work. She can give him answers, right?

Dr. Yoshiba knocks on the door before entering. “Hello, Atsumu. It’s been a while. It looks like therapy is going well. Do you think it is?”

“Yeah, I do. Do ya think I’ll see any more changes?”

“Well, it hasn’t even been a year yet, so it’s definitely possible. Is there something you’re concerned about?”

“Uh, well… My fertility… I wanna know if it’s possible for me to even have kids.”

“Oh!” Dr. Yoshiba rolls her chair closer to him with eyebrows raised. “Well, typically infertility isn’t diagnosed until the couple has been trying to conceive for at least a year. Are you and your partner currently trying?”

Atsumu’s face flushes as he shakes his head.”No, but we’re plannin’ on bondin’ durin’ my next heat... and I wanna be able to… do that when we’re ready.”

“I see. That must be exciting for you.” She taps her chin, contemplating for a moment. “Well, we could run a couple of tests to get a better idea if you’d like. And even if there are issues when you and your partner start trying, there are some treatments that we can try.”

“Okay. Uh, I’ll do whatever tests ya can do.”

“Alright. I’ll take a blood sample and we can do a transvaginal ultrasound so I can get a look at your uterus and ovaries. Do you have a reason to think that you may be pregnant?”

Atsumu’s mind flashes back to his heat a month ago and images of Kiyoomi pounding into him play in front of his eyes. Then he thinks about how Kiyoomi wrecked him the night of the photoshoot and of how thoroughly he was eaten out last night. Biting his lip, he looks Dr. Yoshiba straight in the eyes.

“I don’t think so.”

“Let's do a test just in case.” She hands him a cup and sends him to do his business.

Atsumu holds the filled cup up, looking at it. There’s no way he’s pregnant. He’s on birth control and has a fucked up omega system and… Well, he just has a lot going against him.

He sets the cup where Dr. Yoshiba indicates and watches her pull out a test kit. Then, they wait. It only takes a few minutes before she’s checking the results. When she tells Atsumu that he’s not pregnant, he sighs in relief, though there’s a small pang of disappointment. It’s his inner omega feeling as if it’s failed in producing a pup for its mate. A part of Atsumu thinks that it may not all be just his inner omega.

She proceeds with getting a blood sample and then he’s taken for the ultrasound. When he hears the word “ultrasound,” he thinks of the cold goop spread on a pregnant belly to see a tiny peanut of a baby. He’s not prepared for a wand-looking device to be put inside his vagina. Today he learns transvaginal means “through the vagina.” Fascinating. There’s still goop though.

Dr. Yoshiba tells him that once she takes a good look at the images she’ll call him with the results of this and the blood tests. Overall, it’s a smooth visit, and Atsumu leaves feeling a bit better about everything. He could definitely go for some Omi-Omi cuddles right now though. Or a bath to get the rest of the unsexy lube out.

When he lets himself back into Kiyoomi’s apartment, he can smell eggs and coffee. He smiles to himself. It seems someone finally got out of bed. Padding into the kitchen, he sees Kiyoomi with his bedhead pouring a cup of coffee. When he sees Atsumu, he sets the cup down to embrace him, practically leaning on Atsumu fully.

Kiyoomi’s body radiates a warmth that can only be from those recently awoken. Running a hand through unruly hair, Atsumu chuckles at his alpha.

“Did ya just get up, babe?” Kiyoomi nods, squeezing him tighter. “I woulda come back to bed for a bit.”

“I wanted to have breakfast ready for you.” Atsumu’s heart melts into a puddle. He loves this man. What did he do to deserve him?

“Aw, Omi, yer the best.” Kiyoomi’s chest rumbles with satisfaction. “Let’s eat then.”

He’s begrudgingly released so he can scoop rice out of the rice cooker and place the perfectly done sunny-side-up egg on top. Disturbing the yolk, he lets it run over the rice just like he likes it. Kiyoomi takes a seat next to him at the table with his own bowl.

“How did your appointment go?”

“Good. Dr. Yoshiba said that I could still see more changes since it’s not even been a year yet.” Kiyoomi doesn’t know that he made the appointment about his fertility. He doesn’t really want to talk about that right now anyway. They aren’t there yet, so there’s no reason to worry about it. Besides, everything may come back normal.

“Really?” He looks over Atsumu’s body. “I guess we’ll just have to wait and see.”

A few days later, shit hits the fan. Well, shit being Suna Rintarou and his ridiculous social media following. Jesus Christ, Sunarin. #loveislove is trending, and it stems from Suna’s most recent tweet. There’s a picture of him with his arm around Osamu’s shoulders. Both of them wear small smiles and Osamu is holding up a peace sign.

No, I’m not dating Atsumu. You weren’t that far off though just had the wrong Miya @miyasamu #alphaboyfriend #loveislove

This happened exactly thirteen minutes ago, and Atsumu’s notifications are exploding. Couldn’t they have at least given him a heads up?

Ever since he and Kiyoomi made their announcement, it’s been met with mostly support. However, the hate comments are very… colorful to say the least. For this, it’s a grab bag. There’s support streaming in from several of the V. League players, and then there’s a wave of outrage in the general populace.

Atsumu growls at some of the comments he sees. How dare people say shit about his family like that. Some people are even trying to boycott Onigiri Miya. This is ridiculous! Atsumu didn’t think this would go over well, but this is just on another level. He can’t stop himself from immediately quote retweeting Suna’s post with his own message of support.

I’m so proud of my best friend and brother for coming out with their relationship. I have nothing but love and support for them both. Love you guys

Now his notifications are really on fire.

When his phone rings, he’s honestly expecting it to be either Suna or Osamu, but instead, it’s Dr. Yoshiba.

“Hello?”

“Hello, Atsumu. This is Dr. Yoshiba. I’m calling about your results.”

“Oh, well lay it on me, doc.”

“All your hormone levels look great, and your ultrasound looks completely normal. I think that whenever you and your partner are ready to start trying and you go off of birth control, there’s a high chance of you conceiving without medical intervention.”

Atsumu sits in stunned silence for a moment, just absorbing the information. So… he can actually have kids? Maybe? There’s no glaring problem with his uterus or his hormones being out of whack?

“Atsumu, are you still there, sweetie?”

“Uh, yeah! Sorry. Thanks, Yoshiba-sensei.”

She laughs good-naturedly. “You’re welcome. Take care.”

Tossing his phone on the cushion next to him, Atsumu slumps back onto the couch. Well, that’s one good thing at least. Now there’s just this mess with the media and public opinion. Maybe he should check in with Osamu. Fishing for the phone he just threw away, Atsumu calls his brother.

“I’m guessin’ ya saw Rin’s tweet,” comes Osamu’s bland voice.

“Yeah. Thanks for lettin’ me know ahead of time, asshole.”

“Yeah, yeah. Rin said that ya should be just as surprised as everyone else. Somethin’ about dramatic effect.”

“Of course,” he says, rolling his eyes. And people say that Atsumu’s dramatic. “How are things goin’ though?”

“‘Bout as well as ya’d expect. Had a few people come inside the shop to tell me that I’m a gamma.”

“Yer kidin’.”

“I wish.” Osamu lets out a deep sigh. “I just hope this blows over soon.”

“Me too. What’s Sunarin doin’?”

“His ass is sittin’ in my apartment.”

“Why ain’t he at the shop with ya?”

“I told him to stay inside today. I don’t want him out alone right now.”

“Why? ‘Cause he’s a beta?”

There’s a long pause before Osamu answers, “Ya know it ain’t just that. I know Rin ain’t weak, but I’m worried. Do ya remember what happened to Kodama Ichirou?”

Now that’s a name that Atsumu hasn’t heard in years. When Osamu and he were in middle school, Kodama was a second year in high school. Neither of the twins knew him personally, but they heard enough about him. Kodama was smart, popular, the baseball team’s starting pitcher- already anticipated to go pro - and a beta.

No one knows how exactly how it happened, but the team found out about Kodama’s sexual preferences. Apparently, the baseball team didn’t take kindly to it. Atsumu remembers seeing Kodama at the convenience store after the “incident.” He was in bad shape; his dominant arm and leg were in casts, and his face still wore lingering bruises. Needless to say, he was never quite the same and never played baseball again. The whole ordeal was swept under the rug, and only gossip through the grapevine speaks of it.

“Ya don’t think that would happen do ya?” Atsumu asks hesitantly.

“I dunno. And I don’t wanna find out. Ah, shit. I gotta go. Got some asshole tryin’ to write somethin’ on the window.”

“Alright. Just be careful, ‘Samu. I’ll come down there with reinforcements if I need to.”

“I know. Thanks, ‘Tsumu.”

It takes a relatively large amount of self-control to not call the team and head down to the restaurant. He has full faith in his brother to be able to fend off any vandals. It’s the ones that think they’re big and tough when they’re in groups. After being reminded about Kodama, Atsumu truly understands his brother’s worry.

A week later, the media has died down, but the public doesn’t forget that easily. Getting cat-called on the street isn’t new, per se, but it’s happening a lot more often now. Suna and Osamu have had a few verbal confrontations, but nothing serious has come of it. It’s tiring, but manageable.

In the middle of the week, Atsumu gets a call from Suna. Kiyoomi is out with Komori since he’s visiting right now, so Atsumu is watching a documentary by himself.

“Heeey, Atsumu, buddy, friend.”

“What the fuck did ya do, Sunarin?” he asks with a long-suffering sigh.

“Okay, so I may have broken Osamu’s rice cooker.” Atsumu bursts out into laughter. Suna is a terrible cook, but this is a new low.

“How the fuck did ya manage that?”

“I don’t know! I think it’s possessed. That’s the only explanation.” Sure it is.

Wiping a tear from his eye, he asks, “So why’re ya callin’ me?”

“For you to help me pick out a new one to replace it with so he won’t know.”

“If ya think he’s not gonna notice, yer an idiot.”

“Just come help me pick out a nice one. They all look the fucking same to me.”

“Alright, alright. Jeez.”

“Thanks, bestie,” Suna says sarcastically. Atsumu rolls his eyes so hard it hurts.

They meet up at the bus stop between Osamu’s apartment and the complex like usual. There aren’t too many people out at this time of day, so they should be able to get the job done quickly. There will be no time for Osamu to even miss his old rice cooker.

Atsumu texts Kiyoomi to let him know where he’s going and gets a reply saying that he and Komori will tag along if they’re still at the stop when they arrive. The bus won’t be here for a good fifteen minutes, so there’s definitely enough time. He imagines Komori pestering Kiyoomi for them to go, and it brings a smile to his face.

Suna is showing Atsumu some dumb TikTok when a voice draws both of their attention.

“Well, if it isn’t the alpha-omega and omega-wannabe themselves.”

Atsumu stiffens, scenting the air. Alpha. Multiple alphas. Turning, he sees five of them. Jesus Christ. His instincts are telling him they need to leave. Right now.

“Nope. Don’t know them. We’re just a beta and omega, minding our own business, and you should too,” Suna says, deadpan. Atsumu can tell that he’s tense though. Neither he nor Suna are particularly good at backing down from a verbal spar, but right now is not the time to provoke them.

“Ooh, he’s a sassy beta bitch,” another says.

“Maybe we should show him his place. Clearly, his little puny-knot alpha can’t.” Atsumu grabs the back of Suna’s shirt and tugs when he feels him lurch forward. They can’t fight them all, and there’s nowhere to run; they’re surrounded.

“Look, guys, we don’t want any trouble. Just leave us alone,” Atsumu tries.

The air suddenly becomes thick with pheromones. It’s suffocating, and Atsumu feels his mind revolting at the smell. Are they seriously trying to scare them into submission? Fuck these guys. He growls at the alpha he’s identified as the leader.

The man raises an eyebrow mockingly. “Oh, so you need to be put in your place like the brood cow you are. Come on boys, let’s show them.”

He and Suna take on fighting stances, guarding each other’s backs. This is bad. Really bad. Neither of them are small men by any means, but five is just too many. Plus, Suna has never been a particularly good fighter. Sure, he’s strong, but it’s not like he knows how to fight. He didn’t grow up with a twin or feel the need to intervene in the past. Instead, he found amusement sitting on the sidelines to watch.

Atsumu’s heart pounds in his chest as a man lunges at him, but he easily socks him in the nose.

“You little bitch!”

There’s some shuffling behind him, and Atsumu hears a couple of growls. Suna grunts in pain, but Atsumu is dealing with the asshole in his face with blood gushing from his nose. Out of the corner of his eye, he sees one of the other alphas throw a punch that’s followed by another grunt from Suna. Fuck, fuck, fuck!

His minor distraction allows the man in front of him to grab his wrist, but Atsumu swiftly knees him in the groin. He goes down to his knees with a pained groan. Fucking piece of shit.

“Atsumu, behind you!”

Suna’s shout comes too late as he’s caught from behind in a chokehold. “Couldn’t even deal with a simple omega. Pathetic,” the man holding him says to the guy still clutching at his family jewels. Atsumu panics internally when he realizes the one that has him is the leader.

He’s turned to face where Suna is being held down flat on the ground by two guys, his cheek pressed against the rough pavement. Atsumu struggles in the man’s grasp, but he squeezes tighter, making it futile.

One of the men looks down at Suna with disdain. “You’ll really be living up to the name null if you can’t even play volleyball. Good for absolutely nothing.”

“Fuck off!” Suna yells, earning a kick to the side. Oh god. Suna's hurt. Atsumu scans around frantically. There’s no one except these alphas laughing and jeering at them.

Atsumu breathes hard, trying to get air. His heartbeat pounds in his ears. What are they going to do to them? He’s never been this scared before, not even when the alpha in the club tried to take him away. Kiyoomi had saved him. Wait—

Just as the thought enters his mind, a familiar scent breaks through. One of the men holding Suna is suddenly on the ground, and a snarl rips through the air. Kiyoomi stands there with Komori running from further away, still trying to catch up.

“Release my omega. Now!” Kiyoomi’s body twitches and a vein bulges in his neck. He looks seconds away from snapping.

“Or what?” The man asks, petting Atsumu’s hair mockingly. The last straw is when he leans down to press a kiss to Atsumu’s temple. Gross. Atsumu swears he sees Kiyoomi’s eyes flash red. The other alpha holding Suna backs away, sensing something he wants no involvement in.

“Kiyo!” Komori shouts, finally having caught up. He kneels next to Suna and has his phone out.

It’s all happening so fast. Atsumu is suddenly released, and Kiyoomi has this guy on the ground, beating the shit out of him. “How dare you lay your filthy hands on him!”

“Omi!” Atsumu’s shout gets Kiyoomi’s attention, and he can immediately tell that Kiyoomi isn’t all there. His eyes are completely dilated, and the tense stature isn’t one Atsumu associates with him. There is literally blood on his knuckles and Kiyoomi doesn’t seem bothered at all. He knows what this is, and this can go sideways fast. Kiyoomi’s rut has been triggered.

Trying again, Atsumu calls to Kiyoomi in a gentle voice, “Alpha?” Kiyoomi is at Atsumu’s side in an instant, embracing him tightly. He growls at Suna and Komori over his shoulder.

“Atsumu, you need to get him back home.” He turns his head to see both Komori and Suna baring their necks submissively. Suna has managed to move to a sitting position. He looks relatively fine.

“What about—”

“I called the cops. Three of them ran, but we have these two,” Komori says.

“Rin—”

“I’m fine. Just a little banged up. Osamu will take care of me,” he says with a slight smirk. “Get Sakusa out of here.”

Atsumu nods and turns his full attention to his displeased alpha. “Hey, Omi.” He runs his fingers through dark hair. “Ya did so good. Such a perfect alpha, protectin’ me.” He can feel the deep rumbles in Kiyoomi’s chest pressed against his own.

“I protected my mate.”

“Yeah, ya did. Can we go home now? Let me take care of ya.” Those dark eyes look like they’ve been set ablaze. He picks Atsumu up in a princess carry like it’s nothing, making him squeak in surprise. Alphas in rut are stupidly strong.

“Yes. Then I’ll breed you.”

Atsumu swears he hears Suna choke, but Kiyoomi has already taken off down the street. He’s not scared by any means, however, he’s a little anxious with the anticipation. Kiyoomi’s rut was meant to be two more months from now. Neither of them are quite prepared, and Atsumu has no idea just what he’s in for. Though as the complex comes into view, he supposes that he’s about to find out.

Chapter Text

As soon as they enter Kiyoomi’s apartment, Atsumu’s back is slammed against the wall. He’s held up by his thighs with his legs wrapped around Kiyoomi’s waist. There’s no time for Atsumu to even breathe before Kiyoomi’s mouth is on him, devouring him in a heated kiss. Sharp teeth nip at his lips and across his jaw and trace down his neck.

“Omi— Omi careful. Don’tcha bite through my collar!” He’ll be damned if Kiyoomi ruins this one with his impatience. “Didja just fuckin’ growl at me?”

Atsumu is somewhere between incredulous and severely turned on. Now that the adrenaline from the altercation with the alphas has subsided, Atsumu is left with intense arousal. His alpha fought for him and protected him and came out as the unrivaled victor. What more could an omega ask for?

The flood of pheromones that Kiyoomi lets off is intoxicating. The usual sandalwood is more potent combined with the introduction of the smoky-sweet scent of myrrh from Kiyoomi’s rut. Atsumu wants to bathe in it, drown in it, let it permeate into his very being. To say that it’s starting to affect him is an understatement.

Kiyoomi continues his aggressive scenting and ruts against Atsumu’s quickly hardening cock. Atsumu swiftly unclasps his collar, and as soon as his neck is open, Kiyoomi zeros in on it. The attention to his mating gland causes him to let out a small whimper. Kiyoomi pulls back, his eyes flashing, then pushes Atsumu further into the wall to stabilize him and rips his shirt off. Atsumu moans and his grasp on the collar falters, allowing it to fall to the floor as Kiyoomi attacks his bare chest, licking and biting on his nipples. He pants harshly, feeling slick beginning to soak his pants, and buries a hand in Kiyoomi’s hair.

Kneading Atsumu’s ass, Kiyoomi rolls his hips forward, searching for more contact. He mewls at the friction and holds onto the curly locks tighter, pressing closer. Atsumu can barely think with the overwhelming scent filling the air. His thighs tremble with need as he clings to his alpha, gasping out quivering breaths.

A commotion in the hallway catches Kiyoomi’s attention, and he freezes. Atsumu, paying it no mind, whines to regain his alpha’s attention. However, Kiyoomi growls towards the door while gently setting Atsumu down, and for the first time since they came home, his feet touch the ground.

Slumping against the wall, he watches Kiyoomi stalk over to the entrance. The alpha takes off his shirt and stuffs it in the crack under the door and proceeds to wipe the oil being produced from his scent glands around it as well. He prowls around the apartment, ensuring his scent coats every surface. Every so often his eyes will dart to Atsumu, making sure he’s still there. Tracking Kiyoomi’s movement with heavy-lidded eyes, he admires the form of rippling muscle.

The heady scent of his alpha makes Atsumu breathe heavily. Usually, this is done during pre-rut. However, with Kiyoomi being thrown into a full-fledged rut so suddenly, all of his instincts are crashing into him at once. It’s confusing. It’s dangerous. Atsumu wants to help in every way possible, but all of his knowledge of ruts seems to have flown out the window. Ideally, he needs to calm Kiyoomi enough so he can take back control from his inner alpha. However, Atsumu’s own inner omega is responding to the alpha currently in control, and he involuntarily lets out a whine. Kiyoomi comes back to him immediately.

“You’re safe now,” he says, resting a hand on Atsumu’s hip. “We’re in our den.” Our den. Atsumu can’t help the flood of pheromones he lets out and bares his throat, causing Kiyoomi’s nostrils to flare.

Kiyoomi tears at Atsumu’s pants, yanking them down, uncaring if they remain in one piece. One of Atsumu’s shoes goes flying. He treats his own clothes much the same way. When they’re both naked, he has Atsumu caged in against the wall again. Kiyoomi’s chest heaves with each breath and stares at him with piercing, dilated eyes.

“C’mon, Omi, take what ya need.” Atsumu licks his dry lips, Kiyoomi’s eyes following the movement. “I’m yers.”

That’s all it takes for him to snap. He hoists Atsumu up and hooks the backs of his knees into the crook of Kiyoomi’s elbows. Pressing back, Kiyoomi practically folds him in half—right there on the wall, a bruising grip on his waist anchoring him. Atsumu gasps at the stretch of his muscles. It doesn’t hurt, in fact, it feels amazing. He’s completely on display for his alpha who is looking at him ravenously.

Between the pheromones, the display of strength, and Kiyoomi being Kiyoomi, Atsumu is dripping with slick. It doesn’t take much for Kiyoomi to press his cock fully inside with one motion. Atsumu groans at the feeling. At this angle, Kiyoomi feels so deep inside of him. He’s so full, so good.

“Yes, you’re mine.” He begins up a steady pace, breathing harshly into Atsumu’s neck. “Mine. Mine. Mine.” With each chant of the word, Kiyoomi’s thrusts become harder, faster, leaving Atsumu a wailing mess. He latches onto Kiyoomi’s hair and shoulder with a death grip as each powerful thrust threatens to push him up the wall.

“Yers!” The word comes out shrill, mixing with Atsumu’s moans and screams. His walls pulse around the thick cock inside of him, and he already feels close. His prostate is being nailed every single time, and his orgasm hits him like a giant wave.

As cum shoots from his cock, the spasming of his walls keeps the rush going. Kiyoomi doesn’t stop pounding into him, only drawing it out more. When he bites into Atsumu’s neck, he screams out Kiyoomi’s name with another wave washing over him. The alpha groans with his teeth still latched on as he comes deep inside as his knot inflates. The amount of cum Atsumu can feel gushing inside of him is frankly ridiculous. Amazing. Ridiculous.

As teeth finally release him, Atsumu slumps into Kiyoomi’s hold. Holy fuck. He’s still folded against the wall, never having moved in the alpha’s strong grip. Kiyoomi tends to the bite mark, lapping at it with his tongue and adjusting Atsumu’s legs to wrap around his waist. Then they’re moving. Kiyoomi keeps him firmly slotted on his cock, but slight jostling is inevitable. The knot inside of him presses and rubs torturously against his clit, making Atsumu want to both grind against it and shy away from overstimulation.

Atsumu noses as Kiyoomi’s sensitive scent glands and licks at the swollen mating gland right below it. His mouth waters, aware that he could bite down into it, claiming Kiyoomi as his forever. That’s what was supposed to happen in July with their synched cycles. For a moment, he briefly mourns the loss. Having this powerful alpha as his mate elicits a primal response. However, it’s not just that. It’s because it’s his boyfriend, his lover, his Omi.

When Kiyoomi lays him on the bed, he’s throbbing. The low rumbles in the alpha’s chest settle in Atsumu’s abdomen. He clenches down on the cock inside of him with a small whine, and a large hand wraps around his hip possessively.

“Atsumu.” His voice is low and filled with a deep timbre. Atsumu hasn’t even noticed that Kiyoomi’s knot went down until he’s being thrust into once again deep and hard. “Going to breed you. Fill you with my cum until you’re round with my pup.”

Atsumu moans at the thought as his legs are pressed back. Kiyoomi is completely on top of him, driving his cock down into him. He can feel the cockhead pounding into his cervix, making his eyes roll back into his head. It’s so good. Part of him imagines Kiyoomi releasing his load, pushing through the tiny opening right into his uterus. It’s impossible, but it makes Atsumu throb. Who knew he had a breeding kink?

“God, yes. Omi, please! Fuck me deeper!”

Kiyoomi has no objections to the request. Holding Atsumu with a bruising grip, he shoves his cock further into him. The obscene wet slapping sounds seem to echo in the room. It has Atsumu screaming out his pleasure with his head thrown back and his spine arched. Clawing at the bedding above his head, Atsumu doesn’t know what to hold onto. Kiyoomi mouths at his neck, never once faltering.

When Atsumu comes, it’s with Kiyoomi’s deep groan in his ear and his teeth embedded in his neck again. He can feel how deep his alpha’s cum is reaching. It’s like his body wants to suck it even further in so not a single drop is wasted.

“My perfect omega,” he says, laying his palm on Atsumu’s abdomen. The act itself is possessive with Kiyoomi’s huge hand splayed over him. “My mate.” However, it’s those two words that have Atsumu completely pliant and begging for more in his pheromone drunken haze.

“Yes. Omi, more. Keep goin’.”

It’s six in the morning. Not even twelve hours have passed, and Atsumu is completely exhausted. His body aches and throbs, however, he still manages to moan uncontrollably while his face is shoved into the pillows. Kiyoomi is a beast. This can’t be normal. There hasn’t been a comedown from his rut at all. There are no waves; it’s just one continuous fuck fest. Even his knots aren’t lasting as long as they normally do.

Atsumu wants to help his alpha, wants to be a good omega. He also wants his Omi to come back to him. He thought after a few rounds he would be alright, but he’s lost track of how many times they’ve gone at it.

“Fu-fuck, Omi,” Atsumu moans, turning his face to the side. Kiyoomi’s heated body presses against his back as he leaves wet, open-mouthed kisses on Atsumu’s neck. Pushing himself back on Kiyoomi’s cock, he feels like he’s on fire. The overstimulation and the need to come fighting against each other. One of his hands grips at the sheets while the other claws at Kiyoomi’s thigh.

“Atsumu, so perfect. Want to— want—” Kiyoomi groans, his hold tightening.

“Yeah. C’mon, Omi. Please.” He shoves his cock inside Atsumu one last time with a guttural moan that leaves Atsumu screaming.

Once he and Kiyoomi are locked together again, Atsumu catches his breath and presses against the alpha behind him. Kiyoomi croons softly into his neck, leaving kisses right on the nape. Atsumu allows himself to just lay there in contentment for a while, however, he needs to take care of his alpha.

“Omi,” he tries when Kiyoomi starts to shuffle behind him as his knot goes down. There’s no response other than a grunt as he grabs Atsumu’s waist to manhandle him into another position. “Alpha, wanna see ya.”

Thankfully, Kiyoomi listens and flips him on his back. He easily slides back into Atsumu’s sopping wet pussy, beginning to fuck him again. Atsumu moans, despite the puffy walls of his vagina. Kiyoomi just feels so good inside of him. Regaining himself, Atsumu reaches up to hold Kiyoomi’s face in his hands. The alpha looks down at him, his eyes completely black.

“Omi, yer such a good alpha. Look at how much ya’ve filled me up.” He watches Kiyoomi’s eyes track over the form of his distended stomach. A pleased rumble comes from his chest. “Let yer omega take of ya, yeah? C’mon, babe.”

With a bit more encouragement, Atsumu manages to get Kiyoomi on his back so he can ride him. He rises and sinks down on Kiyoomi’s thick cock, pushing his hips down hard. The alpha only manages to stay down for a few moments before he rolls up and wraps his arms around Atsumu’s waist. He rocks his hips, thrusting erratically up into Atsumu’s slick heat.

“Oh, fuck! Kiyoomi!” The pleasure coils tightly in his abdomen with every press against his prostate. Atsumu buries his face in the crook of Kiyoomi’s neck. The alpha’s hands slip down to grip Atsumu’s hips, pulling him down onto his cock.

“Going to breed you. Fuck you full of my pups,” Kiyoomi murmurs against Atsumu’s neck before biting down. Atsumu’s grip on his dark hair tightens as he keens through his release. Hot pleasure rolls through him and his vision goes white. His walls spasm around Kiyoomi’s knot expanding inside of him.

Keeping Kiyoomi’s face in the crook of his neck, Atsumu releases more pheromones and strokes his hair. He begins to purr when Kiyoomi starts responding to his thick scent. Warm hands trail up his back, moving up and down in comfort. Taking Kiyoomi’s face in his hands again, he maneuvers him to look him in the eyes. Emerald green peeks out from behind black.

“There ya are. My Omi-Omi.” He smiles, rubbing his thumbs in small circles over Kiyoomi’s cheeks.

“Atsumu, I’m so sorry. I—”

“Shh.” He presses a chaste kiss against his lips. “Nothin’ to be sorry for, Omi. I can take care of ya too, ya know.”

“God, I love you. I love you so much,” he says before pulling Atsumu into a heated kiss. Responding enthusiastically, Atsumu leans into Kiyoomi and parts his lips, allowing in the wet slide of his tongue. “Fuck. I want to fuck you again.”

Atsumu chuckles, pulling back. “Down there, boy. Ya need to eat and drink somethin’ first.” Kiyoomi groans, resting his head on Atsumu’s shoulder.

“You have no idea how irresistible you are. My alpha wants my cock inside you at all times.”

“Well, I mean, I’m not exactly opposed to that.” He feels Kiyoomi’s cock twitch inside of him. Seems like Omi isn’t opposed to that either, he thinks, giggling. Kiyoomi quiets him by kissing him again, and they continue until his knot deflates.

Kiyoomi avidly watches the copious amounts of cum of slick gush out of Atsumu as he lifts off of Kiyoomi’s cock. It smears down the inside of his thighs and onto Kiyoomi’s stomach. However, the alpha only licks his lips and pushes Atsumu back, making him lose his balance at the unexpected force. He spreads Atsumu’s legs open and trails two fingers through the liquid, collecting it. Then he shoves it back into Atsumu who moans when Kiyoomi presses on his clit.

“You're still so wet.”

“Of course, I am. And I’ll still be after we eat.” He tries to worm his way out of Kiyoomi’s hold.

“But, Atsu, your pussy is begging for me.” Kiyoomi captures more of the sticky liquid and brings it to his mouth, sucking it off his fingers. He smiles shark-like. “Tastes good enough to eat too.”

Atsumu barely has enough time to prepare before Kiyoomi’s tongue is inside of him. He groans with satisfaction when Atsumu grabs his hair, pressing into him further.

“Omi— oh, god. Please—” he keens. “I can’t—”

Kiyoomi licks into him like he’s a five-star meal. The sounds. They’re filthy. Atsumu pulls on Kiyoomi’s hair and squirms, but he doesn’t relent until Atsumu comes, slick gushing down his thighs. His dick remains limp against his stomach.

Atsumu’s chest heaves as he pants. Kiyoomi only licks the remaining slick off his face with a smug look. Then he gathers Atsumu’s pliant form in his arms and heads to the kitchen. They’re still naked. Atsumu is a little worried about what Kiyoomi may be thinking.

Atsumu is trying to make some lunch for them, but Kiyoomi can’t keep his hands to himself. He’s plastered to Atsumu’s back, and he can feel the hard dick rubbing against his ass. Insistent hands travel down his stomach and feel up his thighs and hips. Fingers only tease at his entrance along with the featherlight touches to his cock, twitching in interest.

“Atsu,” he says, leaving open-mouthed kisses on his neck. “Want you.”

“Omi, I’m tryin’ to cook. Can’t ya wait like five more minutes?”

“No.”

Atsumu gasps as he’s pulled away from his work and bent over a different area of the counter. Kiyoomi leans against him, gathering a wrist in each hand to press to the counter. He spreads his legs further apart so Kiyoomi can push inside him all at once. Meeting each powerful thrust, Atsumu moans as heat fills his body. His flushed cheek presses against the cool surface and his tongue lolls out.

“So good for me, my perfect omega. Ready to take my cock like you’re made for it. Made for me.” He snarls, increasing his pace. “You’re mine.”

Atsumu wails.

The food ends up burning. Kiyoomi doesn’t seem to care though. He’s perfectly content eating his protein bar while Atsumu sits on his cock.

“Yer a beast, Omi.”

“You know I usually take a low dose of suppressants. My hormone levels are a little high.”

“A little,” he scoffs. “I just didn’t think about how that would factor into yer rut. Not to mention it bein’ triggered.” Kiyoomi growls at the reminder of what caused his early cycle. Atsumu is able to quickly soothe him though by caressing his face and releasing a few pheromones.

“Thank you for putting up with me,” he says, nuzzling at Atsumu’s temple.

“It’s not puttin’ up with ya. I’m just takin’ care of my alpha.”

Atsumu lets Kiyoomi use him like a fuck toy. His voice is hoarse and he’s pretty sure he’s been fucked on every single surface in the apartment. How the hell did Kiyoomi manage to keep up with his heat so well? Though Atsumu doesn’t think his heat was anywhere near this level. He wishes that he was in heat right now. Then he’d be a more active participant, and they’d bond. Atsumu is a little put out about that. He was looking forward to it. Now when will they be able to do it? That’s something they’ll have to figure out later. For now, he’s focused on Kiyoomi’s rut.

Atsumu feels completely boneless. It’s been three days, and it seems like Kiyoomi’s rut isn’t nearing its end. He’s covered in Kiyoomi—his scent, his cum, his love… Not to mention that he has spent basically the entire time on Kiyoomi’s persistent erection. Whether they’re eating, talking, or sleeping there’s a dick inside of him. Honestly, he rather likes it since just sitting there doesn’t agitate the soreness his body feels. Actually, he loves it. He feels so close to Kiyoomi. Atsumu can tell that Kiyoomi is a fan as well.

Kiyoomi is much more clear-headed now. It’s obvious just through his eyes. He’s once again completely in control of his alpha. That doesn’t mean he’s completely out of his rut yet though. Atsumu has the feeling that this rut is going to be longer than the typical three days. It’s not uncommon if a rut is triggered like Kiyoomi’s. It’s fine. As long as he pleases his alpha and takes care of him, Atsumu is happy. He’s a good omega.

Kiyoomi hovers over him, situated between his legs. His gaze travels over Atsumu’s thoroughly marked body. Dropping down, he laves kisses over every bruise. Soft black hair tickles along Atsumu’s stomach, tracing the heated trail of kisses.

“I was rough with you, wasn’t I baby?”

“Mm. S’okay, Omi. Was I good for ya?”

“So good. Perfect.” Kiyoomi lays over him, letting his hands roam Atsumu’s pliant body. “Can you keep going?”

“Yeah.” He sighs into the gentle touches. “Take everythin’ ya need, Kiyoomi.”

Atsumu means it. He may be tired, but that doesn’t mean he’s not still enjoying this. He wants to see and love every side of Kiyoomi, and ruts are a part of that. Sharing something so intimate with someone brings them closer together. He craves the connection. Plus, the sex is fantastic.

“You’re sure?” he asks again, beginning to line up his dripping cock at Atsumu’s entrance.

“Yeah.”

He sighs as Kiyoomi enters him, feeling the mouth-watering drag of his cock. It’s amazing how wet he still is despite how much they’ve fucked since he’s not in heat. Maybe that’s just what Kiyoomi does to him.

“God, you feel so good. You’re still so wet and tight.” Kiyoomi rolls his hips just the way Atsumu likes, pulling a moan from him. “And you sound so pretty.”

That slow push of the cockhead entering him each time drives him insane. Whimpers fall from his lips, igniting Kiyoomi’s fervor. He speeds up but still tries to be gentle. Kiyoomi’s hands bracket his head, keeping him steady over Atsumu. Raising his legs. Atsumu wraps one over Kiyoomi’s lower back. The other rests against his thigh. His fingers map Kiyoomi’s handsome face, brushing a few curls away from his forehead.

“Love ya, Omi.”

Even through the lust of his rut and the pheromones, Kiyoomi’s eyes shine with unadulterated love. “Love you too. Want you to be mine forever.”

Atsumu keens, arching his back. “Bond me, Omi!”

Kiyoomi sinks his teeth into Atsumu’s mating glad, breaking the skin. Pain and pleasure rush through him, but it’s mostly pain—both physical and mental. Mental because Kiyoomi can’t bond him right now, and he wants it so desperately. Unable to repress his sob, hot tears roll down his cheeks, and he clings to Kiyoomi’s shoulders.

“Shh. It’s okay, baby,” Kiyoomi says, lapping at the wound and trying to soothe him. Adjusting himself, he thumbs away Atsumu’s tears and licks into his mouth to quiet his cries. All the while, he continues to roll his hips.

“Want ya. Want ya, please.”

“You can bond me, baby. Tie me to you forever.” The offer causes Atsumu to release a high-pitched whine. He really contemplates it, staring at Kiyoomi’s bared neck through watery eyes. That’s not what he wants though.

“No, I wanna bond together. Wanna do it together.”

“You’re perfect,” Kiyoomi groans, running his hands down Atsumu’s side to settle on his waist. His fingers press into the soft skin as he begins to pound into Atsumu. “My perfect omega, wanting to be claimed by his alpha.”

“Oh, fuck! Omi, Omi, Omi,” he babbles.

It feels too good, sending little shocks through his body. Kiyoomi leans down, sliding his tongue into Atsumu’s mouth. Clawing at the alpha’s back, Atsumu pants hotly into his mouth and trying to match Kiyoomi’s rhythm. It’s wet and sloppy, drool and moans spilling from him. The throbbing in his dick as it rubs against Kiyoomi’s hard abs and pussy clenching on the cock inside him has Atsumu teetering on the edge.

“Come for me, omega, and I’ll give you my cum, shove it deep inside you.”

After only two more thrusts, Atsumu comes hard, his mouth open in a silent moan. Kiyoomi follows with a deep groan buried in Atsumu’s neck. He runs his hands over Atsumu’s flushed body, touching everywhere he can reach. At the moment, his vision is hazy, black spots ebbing in and out.

“Rest, Atsu,” Kiyoomi says, rolling so that Atsumu can lay comfortably on top of him while they’re tied together. His last bit of consciousness slips away with the feeling of a kiss being pressed to his head.

Atsumu hisses as he’s helped down into the hot water. It feels amazing on his sore muscles, but the unhealed wounds on his body sting. He manages to settle himself against Kiyoomi’s chest. Strong arms wrap around him and Kiyoomi rests his chin over his shoulder. Even though his rut is over now, he can’t seem to pry himself away from Atsumu for even a moment. It’s kind of cute.

“You really are amazing, you know that?”

“Well, I am a pretty extraordinary omega.”

“It’s not just that.” Atsumu turns his head to Kiyoomi, cocking it slightly. “It’s everything, Atsumu. Everything about you is extraordinary.”

Atsumu’s eyes crinkle, a small smile playing on his lips. “Thank ya, Omi.”

“I love you, Atsumu. I know our plan to bond in July can’t happen anymore, but I promise that next time nothing is going to stop me from making you mine.”

“I’m gonna hold ya to that,” he says, snuggling into Kiyoomi’s embrace only to feel a growing hardness against his lower back. “I thought yer rut was over.”

“It is. Just ignore it.”

“Can’t resist me, Omi-Omi?”

“No, I can’t,” Kiyoomi groans, turning his head to press his forehead to Atsumu’s neck. With a chuckle, Atsumu uses Kiyoomi’s thighs to lift himself up. “What are you doing?”

“Tryin’ to get yer dick inside me, what does it look like?”

“Atsumu, you don’t have to. I’ll be fine.”

“I wanna though. Do ya not?” Kiyoomi’s answer is to grab onto Atsumu’s hips and lower him down on his aching cock, shuddering as he’s filled.

“Oh fuck.” He wraps his arms tightly around Atsumu before leaning back to relax. “Just like this.”

Atsumu sinks into his embrace, sighing in contentment.

“Yeah, just like this.”

Chapter Text

Atsumu’s legs feel like jelly when he attempts to stand on his own. They shake and tremble like he’s a newborn fawn. Kiyoomi watches in amusement from the doorway since Atsumu insisted that he doesn’t need help. After attempting a single step, he collapses into a heap on the floor with a pitiful whine. God, it hurts. He has sore muscles that he didn’t even know he had.

“Ooomiii,” he whines, stretching out his arms. Kiyoomi chuckles, approaching him.

“I’ve got you, baby.” He scoops Atsumu up and carries him into the kitchen, depositing him on the counter.

As Kiyoomi rustles in the cabinets, Atsumu takes a look around. They really made a mess. It’s no that he’d say Kiyoomi’s apartment is dirty, it’s never dirty, but it definitely needs a good cleaning. However, Atsumu doesn’t think he’ll be much help in that department today.

He also knows that Kiyoomi is more tired than he’s letting on right now. They both laid in bed for a good two hours after waking up. Honestly, Atsumu could go for an IV drip of fluids right now. When Kiyoomi hands him a glass of water he downs it all without taking a breath. This rut was hard on both of them.

Atsumu is still scheduled to have his heat in a couple of months, but Kiyoomi’s next rut won’t be until the end of the year at the earliest. He chose to not create a one-way bond with Kiyoomi during his rut even though it was offered to him, and while Atsumu believes he made the right choice, there’s still a part of him that wishes he did it. Will he still be grateful for his restraint when he’s begging Kiyoomi to bond him during his heat? They both want to do this together. Why did everything have to fuck up their plans?

Speaking of things fucking up their plans, he should probably check in with Suna. He looked alright when they left, if not a bit worse for wear. He’s a stubborn bastard, so Atsumu is sure he’s fine. Though, he wouldn’t put it past Suna to be milking it for all he’s worth to get Osamu to baby him.

“Hey, Omi, wouldja bring me my phone please?” Kiyoomi nods and starts to leave, but he stops at the threshold, looking back at him. Atsumu knows his big, bad alpha senses are still tingling, so he’s feeling a bit over-protective, not even wanting Atsumu out of his sight. It’s cute. “Don’t worry, Omi, I’ll still be here. It’s not like I can go anywhere.” He chuckles as the alpha finally relents.

When he returns, Atsumu rewards him with a lingering kiss before taking his phone. He hovers between Suna’s and Osamu’s names before tapping Sunarin. There’s a very high possibility that he is currently holding his phone right now. When the call connects almost immediately, he figures he assumed correctly.

“So you lived.”

“Of course, I did. Ya think Omi was gonna eat me or somethin’?” Kiyoomi sends him a raised eyebrow and a smirk that makes Atsumu flush.

“Well, with the way he looked, I wouldn’t have been surprised.”

Atsumu huffs and rolls his eyes. “I guess this means yer doin’ fine then.”

“Yeah, just a little banged up.”

“What happened to those assholes who jumped us?”

“The police collected the guys we had there, and the other ones were found and brought in. Everything is taken care of, but you and Sakusa will need to make your statements.” Well, that’s good at least. He hears some shuffling on the other end and Osamu’s muffled voice. “Hang on, Osamu wants to talk to you.”

More rustling comes through the receiver as the phone is passed over. “How’re ya feelin’?”

“Tired, but otherwise, good.” He leaves out how sore he is. Osamu doesn’t need to know to what extent he had the life fucked out of him.

“Good. So wouldja be able to come over this evenin’?”

“Uh…” Atsumu pauses, looking down at his useless, hanging appendages. “What for?”

“I— Well… We wanna talk to ya about somethin’.” He senses the slightly serious tone in his brother’s words.

“Omi can bring me over.” Atsumu turns to look at Kiyoomi to check for confirmation and receives a nod in return. “What time?”

“Before dinner sound good?”

“Yep. See ya then.” Atsumu ends the call, feeling a bit perplexed. What in the world could Osamu and Suna want to talk to him about that’s so important?

Kiyoomi doesn’t question him and just hauls him off the counter when he finishes cooking. Atsumu feels as if he’s getting spoiled. Before he started dating Kiyoomi, Osamu was the only person he could consistently lean on. However, now Kiyoomi takes care of him without even thinking about it. He loves how Kiyoomi’s strength makes him feel smaller than he actually is, how he’s loved in spite of his flaws and insecurities, how every small act of service voices his love for Atsumu so much louder than words… It’s a comforting feeling, and he could easily grow accustomed to it. Atsumu wants to give just as much as Kiyoomi does though. For every time Kiyoomi makes Atsumu feel loved and cherished, he wants to return it.

So while Kiyoomi has to carry Atsumu around despite his drooping eyelids, Atsumu does whatever he can that’s within reach. He sits on his alpha’s lap as they bathe, lathering soap in his hair and receiving small, pleased hums. Large hands gently massage his sore thighs as Atsumu continues his ministrations. Rinsing Kiyoomi’s hair of suds, Atsumu presses soft kisses over his face.

His chest feels so warm and full. It’s nothing he ever could have expected, but it’s everything he could ask for. The low rumbles from his alpha’s chest as he runs his hands over broad shoulders make Atsumu completely melt against him. Kiyoomi slides his hands up Atsumu’s sides, just feeling his warmth. While intimate, it’s not inherently sexual. He just enjoys feeling so close to his alpha.

Briefly, Atsumu wonders if it’ll feel any different when they’re bonded. Will this connection feel even stronger? They say when a mated pair is especially compatible, there is something of an emotional connection where they can briefly feel each other spiritually. What would it be like to feel Kiyoomi’s love surrounding him like that? Atsumu believes that they’ll find out soon enough.

They arrive at Osamu’s apartment later that day with Kiyoomi piggybacking Atsumu. He gives Osamu a sheepish smile at his unamused look when he answers the door. It’s not his fault that he literally cannot support weight on his legs. Suna barks out a laugh and then grimaces in pain. Serves him right.

Once Kiyoomi settles him on the couch, he sits next to Atsumu, resting a hand on his thigh. Osamu follows, taking a seat by Suna.

“So what didja wanna talk about?”

“It’s a little crazy,” Osamu says. “Maybe controversial.” Atsumu quirks an eyebrow and flicks his eyes between the two. Well, those aren’t words that usually come out of Osamu’s mouth when talking about himself.

“But we’re far past giving a shit what people say.” Suna jumps in when Osamu pauses. “After being attacked, we’ve actually gained a lot of support, and we want to just do what we want. So we’re going to bond.”

“Pardon?” Atsumu blinks dumbly. Bond? That’s… impossible.

“What Rin means is that we’re gonna do somethin’ that would physically represent our bond, and we wanna know what ya think of our idea.”

“Okay. What do ya have in mind?”

“A tattoo,” Suna says, pointing to the crook of his neck - right where a mating gland would be, “right here of each other’s bite.”

“Oh.” Atsumu stares at them both, stunned. Well, that would certainly get the point across. Then he smiles, thinking of how they will be able to show off this mark of their love for each other. “I think it’s a perfect idea.”

“Really?” Osamu’s boyish smile threatens to break through.

“Yeah.” Atsumu doesn’t know where the hell they thought of it, but it fits them both well. Osamu with his deep-seated desire to bond, and Suna’s mischievous nature to cause trouble. Kiyoomi agrees as well, nodding when they look at him for a verdict. Atsumu squeezes his hand. Their little family supports each other all the way.

Over dinner, they discuss more unpleasant matters such as the attack. Atsumu keeps a hand on Kiyoomi’s thigh to soothe him. It’s almost a little funny that he’s the most worked up about it, but Atsumu would never actually tell him that. It’s actually kind of hot.

Osamu sends him an article about what happened during Kiyoomi’s rut. Pulling it up on his phone, he adjusts so Kiyoomi can read over his shoulder. Apparently, the entirety of MSBY and EJP came down to Onigiri Miya to show their support. In some of the pictures, Atsumu sees other familiar faces, making him smile. It seems the JVA is taking the attack seriously as well.

He’s not sure exactly what this will do, but it’s a start. Also knowing that the league supports them openly is a huge relief. It’s one thing to say it online, but to be physically present sets a different tone. Atsumu can’t help but feel that things are going to be alright.

With summer comes invitations to try out for Japan’s National Volleyball Team. This year is especially important since they’ll be choosing the Olympic roster from those who make the team. It’s no surprise when basically the entire monster generation shows up at the Ajinomoto National Training Center for tryouts.

Atsumu is currently on the JNT roster and has been since 2015 when he made it for the Rio Games, but that can always change. He has to earn his spot like everyone else. Although, he has little doubt that he’ll be playing on the world stage here in Tokyo next year. He’s confident Kiyoomi will be there too.

The only worry Atsumu has is his heat. It’s due in two weeks, and the added stress of tryouts, different surroundings, and several alphas he’s not familiar with is just asking for it to be off schedule. Whether it’s early or late is up to fate, and fate has been rather shitty to him lately. An early heat is the last thing Atsumu needs right now.

It doesn’t help matters that they’re all shoved together in rooms at the training center. He’ll just have to curl up next to Kiyoomi with his face half-buried in the alpha’s neck. So many alphas together smell terrible.

On the bright side, there’s no shortage of entertainment. Gao is still chasing Hoshiumi, and Atsumu almost feels sorry for the guy. Almost. He looks like a kicked puppy as he watches the Adlers and Jackals players gather around Ushijima to ask about his time in Poland.

“The language is very confusing. Satori is picking it up much faster than I am.” He looks happy, and Atsumu doesn’t miss the new mating marks he’s sporting.

It feels like everyone is bonding. Hinata and Kageyama, Bokuto and Akaashi, and now Ushijima and his mate. Even Suna and Osamu will soon have marks. Atsumu runs his hand along his own bare neck. He and Kiyoomi should’ve been getting theirs soon too.

He doesn’t mean to be feeling sorry for himself, but now they have to wait for months. It just makes him feel anxious. Of course, Kiyoomi loves him. That won’t change, but what if something else happens? What if they keep having to push it back?

Stepping away from the group, Atsumu heads to his water bottle for a drink. His head needs to stay in the game. He’s here for one reason and one reason only. So why does he still feel so restless?

“Hey! What’s with the face?” Hoshiumi approaches him with his hands on his hips. “You’re not over here moping over something dumb, right? Because that would be super lame.”

Atsumu frowns because it is dumb. So he changes the subject. “Are ya ever gonna accept Gao’s courtship?”

“I’m going to before we all leave. He doesn’t need to know that though.” He smirks. Then his eyes narrow as he accesses Atsumu. “Is that what this is about? Relationships? I thought you and Sakusa were disgustingly in love.”

“We are! It’s just… we were supposed to bond this month with a synced cycle.”

“And you’re being stupid because you’re in preheat, thinking that he’s going to change his mind or something else will happen before next time?” Atsumu doesn’t answer and wrinkles his nose. Being in preheat would help explain his emotional turbulence. “What? I can smell it all over you.”

He grunts in frustration. Stupid, fucking omega shit. Hoshiumi sighs and leans an arm on Atsumu’s shoulder. “I know that you’re still on about this whole not fitting the classic omegan mold, but what omega in the V. League is a normal omega.

“You’ve done a hell of a lot more for omega representation since you came out than I have this entire time, and to be honest, that just makes me want to do more. You and I are the only two unmated omegas here, so let’s get out there and make this team and show the world how powerful omegas are with or without a mate!”

Atsumu stands up with renewed determination. “Yer right, Kourai-kun. Let’s do this!”

“That’s what I’m talking about!” The two high five with big grins on their faces.

After that little pep talk, Atsumu feels much better. However, as more preheat symptoms begin to manifest and not even scent blockers can keep all of his scent at bay. On the bright side, he and Kiyoomi are moved to a separate room. Now, if his heat can just hold out for another week. He can push through this. It’s definitely not ideal, but things could always be worse.

Kiyoomi sticks by his side wherever they’re off the court. His alpha is so cute. Hoshiumi and Yaku may roll their eyes at him, but at least Hinata keeps sending heart eyes at Kageyama, so he isn’t alone. The issue only comes along when his alpha gets a little handsy. Aran looks particularly affronted when he sees Atsumu being groped.

It’s a little crazy seeing all these players here together on the same side of the net. Everyone here is the best of the best, and not to be biassed or anything, but Atsumu believes that Kiyoomi is the best spiker present hands down. Watching him soar up in the air with that look of complete determination is ridiculously hot. Then when he spikes the ball with a satisfying thud and looks to Atsumu, it makes his heart leap.

Despite his preheat dragging his energy levels, Atsumu himself performs beautifully. His serves and sets are exactly as he wants them. Being an omega may be annoying at times, but that doesn’t make him incapable of performing just as well as anyone else even with the preheat symptoms. Although, he definitely wouldn’t want to be playing in a match like this. He’d do it if he had to though.

The only thing not going as planned is Kiyoomi’s continued disappearances between sessions. He says it’s for family stuff, but why isn’t he bringing Atsumu with him? He wants to see Akira too. Kiyoomi remains tight-lipped. Even Atsumu’s puppy eyes aren’t working, and that always works. Considering how clingy he’s being, it’s surprising that he’s choosing to leave Atsumu alone. Why is he being so secretive?

When Atsumu approaches Komori about it, he pretends to be clueless, but he definitely knows. Growing up with a twin has made Atsumu adept at knowing when someone is bullshitting. Komori is a grade-A bullshitter. Kiyoomi isn’t ever gone for long and is always back before dinner time. What the hell is he doing?

He never quite finds out because as soon as tryouts end, Atsumu goes into heat. Kiyoomi rents them a room at a heat hotel, and that’s where they spend the next few days. Kiyoomi fucks him through it thoroughly. He remains vigilant and doesn’t bond Atsumu, which he’s ultimately glad for, even with his heat influencing him. It doesn’t mean his inner omega is happy about it though.

The hotel is comfortable enough, but he would have rather been at home where he had time to build a proper nest. Nothing smells like them, and it’s rather off-putting. Okay, so maybe he’s a little bit of a bitch during his heat. He’s eternally grateful that Kiyoomi takes care of him and apologizes for being so needy.

The train ride home is a blur. Atsumu is pliant and groggy from his heat, but he still insisted that they get home as soon as possible. The added stress from tryouts really zapped all the energy he had. He just wants to relax in his nest with his alpha. All that he recalls is Kiyoomi’s arms around him as he drifts off to sleep.

The JNT roster is posted in August. Who will be on the Olympic Team won’t be announced until October. However, with Suna, Kiyoomi, and Atsumu all making the team, it calls for a small family celebration. It’s nothing fancy. Actually, the four of them just plan to order in and watch movies.

“Lemme see it!” Atsumu says as soon as the door to Osamu’s apartment opens.

Osamu tilts his head to show off the wrapped tattoo that was finished earlier in the day. It’s obviously still red, but it’s reminiscent of a real, fresh mating bite. The tattoo itself is an exact replica of Suna’s bite. Not that Atsumu would know—that’s just what Osamu said. Osamu seems incredibly pleased with his puffed-out chest and other typical alpha posturing. If this was under any other circumstances, Atsumu would tease the hell out of him, but he has every right to be proud of his mating mark.

Atsumu’s next victim to be inspected is lazing away on the couch. Plonking himself on Suna’s lap, he tilts his head to the side. And there it is—Osamu’s bite mark in the form of a tattoo.

“It’s kind of surreal, isn’t it?” Suna says.

“Kinda. It looks so real.” Perhaps that’s why it’s a little crazy. Betas can’t give or receive true mating marks. With how realistic these are though, it will definitely cause people to look twice.

“I know it’s obviously not the same, but I still feel a little different.”

“Ya may not have a traditional bond, but yer still bonded in spirit. I think the mindset has a lot to do with it too.”

“Oi, ya scrub, get offa my mate,” Osamu says, a smile spreading across both his and Suna’s face at the choice of words. They’re stupidly in love, and Atsumu can’t really fault them for it.

“Yeah, yeah. Didja order the Thai food?” He slides off of Suna’s lap and looks up to face his brother.

“Of course, I did. Who do ya think I am? Kiyoomi went down to bring it up.”

In the amount of time Atsumu and Osamu are distracted, Suna has managed to navigate to some streaming site on the tv to select a movie. Atsumu takes one look at Suna’s selection and jolts for the remote.

“Oh, hell no! We ain’t watchin’ one of yer shitty horror movies!” Neither Atsumu nor Osamu like horror. It freaks them out. He remembers when they were eight and stayed up late watching some American horror film. They huddled together in Osamu’s bunk the entire night.

Suna maneuvers away, keeping the remote out of reach. “Oh come on. This one’s good.”

“‘Tsumu,” Osamu says, nodding to him. He nods back as they both try to wrestle for the remote. Suna is just so damn bendy.

“What are you doing?” Comes Kiyoomi’s voice. The three of them look up to see him standing with the bags of take-out.

“Tell Sunarin that we ain’t watchin’ his horror movie!”

“Hmm.” Kiyoomi looks at the screen, thinking. “Oh, this is based on the Steven King novel. I’ve never seen it, but I’ve heard it’s good.”

“Ha!” Suna wiggles free, gloating because he knows he’s won.

Atsumu and Osamu lay on the floor, groaning in defeat. At least he has a strong Omi-Omi to protect him from the terrible monsters.

Chapter Text

Atsumu wakes up on October fifth in a much different place than a year ago. At the age of twenty-four, he awakens in the warm embrace of a lover with a feeling of contentment that has grown more and more familiar. The scent of sandalwood surrounds him in a gentle caress, and the man it permeates from lays asleep with the morning glow soft on his face. Atsumu’s head rests on his shoulder and softly grazes his face with the tips of his fingers.

Last year, he had just gotten his first dose of omega hormones and was facing an entirely new set of challenges. Now Atsumu can proudly say that he’s an omega and stands tall with pride. While there are still challenges, he knows that he can face them; and he’ll never be alone. There are people who love him for who he is, who will support him, who will stand by his side every step of the way.

Then there’s Kiyoomi. He’s in a category all his own. Only in his wildest dreams could he have ever held the image before him. Atsumu has known several types of love, but none compare to the love he feels for Sakusa Kiyoomi—his alpha. Atsumu can’t imagine a forever without him.

Kiyoomi stirs, catching Atsumu’s hand with his own and kisses the inside of his wrist. Slowly, he opens his eyes, and Atsumu is struck with a flood of warmth in his chest.

“Mornin’, Omi.”

“Good morning, love.” He pulls Atsumu closer and murmurs against his lips, “Happy Birthday.”

Atsumu melts into a kiss, cupping Kiyoomi’s jaw. Soft and languid movements allow him to feel every ounce of love shared between them. Affection curls in his stomach, butterflies and all. He wants to wake up like this every day.

It’s a slow morning since they have a home game tonight. There’s enough time for Kiyoomi to make love to him in the comfort of their bed and for them to take their time together in the shower. It’s moments like this that Atsumu is still in awe of—that he’s allowed to have this. This life is everything he could ever want and more.

As luck would have it, they’re playing EJP tonight, so Suna is in town early to spend the day with Osamu. Usually, Atsumu would be there too, as per traditions, but this year is a bit different. With the game later, it throws a bit of a wrench into their usual plans, but that’s alright. Now Atsumu gets to indulge in more alone time with Kiyoomi. Plus, he’ll see Osamu tonight. Maybe the four of them can start some new traditions together.

The entire time they’re on the court, Atsumu feels this strange energy radiating from Kiyoomi. He’s still perfectly on his game, but there is just something… off… All the while, he can feel the holes being burned into the back of his head from the alpha’s staring.

Normally, he would attribute it to Kiyoomi being a horny bastard, but they had sex this morning. Though he still shouldn’t count that out as a possibility. If it wasn’t for how odd the whole thing feels, Atsumu would be more inclined to believe it.

Even Suna is acting weird. Okay, weird is a strong word. Atsumu only notices because he’s very familiar with all things Suna Rintarou. Sending him a look from across the net just earns him a smirk. It’s enough to piss Atsumu off and dump the ball right in front of him. The smirk turns into a frown, and he’s very pleased with himself.

The Jackals take it after four sets.

“Omi-kun!” he calls, setting the ball. And there he is—Kiyoomi leaping into the air to deliver a spike with that disgusting spin. He’s right there where Atsumu expects him to be, a constant by his side.

Kiyoomi’s feet return to the ground as the whistle blows, signaling the end of the game. As Atsumu bounds towards him, the alpha’s gaze is already settled on him. He easily catches him around the waist, smiling as the rest of the team joins them.

A bead of sweat runs down Kiyoomi’s forehead, and Atsumu is once again struck by how lucky he is. He’s able to play on the same side of the court as his lover. His very handsome lover. The way he pushes back his sweat-damp curls drives him mad.

The team is extra rowdy in the locker room. It seems everyone is ready to celebrate tonight. Hinata keeps grinning at him, and maybe that should have been Atsumu’s first indication that something’s up. However, he’s too caught up in his own victory and is ready to shove it in Suna’s face.

Instead, Atsumu’s first clue that something is going to happen is when rather than walking down to the izakaya, they’re driving somewhere. The second is when they pull up in front of the Conrad Osaka. Third is when Kiyoomi checks them into a room. When Atsumu questions him, the answer he receives is, “It’s for your Birthday.” Okay. Sure.

Needless to say, he’s suspicious. Although, maybe he shouldn’t be since it’s no secret Kiyoomi’s idea of a gift is a bit… over the top.

So when the elevator opens to the Sky Bar & Lounge on the fortieth floor, Atsumu can only gawk at the fancy interior and huge floor-to-ceiling windows. Both teams are here and look completely at ease like this has been a plan for a while—and it probably has.

“Omi, this is a lot.”

“Well, part of it’s for Osamu too. Suna thought it was a good idea.” Of course, he did, the bastard. Atsumu can see him downing a glass of champagne over there with Osamu.

Atsumu looks at Kiyoomi and seeing his sincere face has him reaching out to cup his cheek. “Thank ya, Omi.”

“Of course.” His eyes crinkle, and he takes Atsumu’s other hand to lead him.

Both teams look like they’re in heaven with all the different food to choose from, and something tells Atsumu that Osamu might have to be wheeled home. Then there’s Suna with his quickly growing collection of empty champagne flutes. What a disaster.

He’s pulled away from Kiyoomi by an enthusiastic Hinata to dance. They’re joined by Akaashi who does not shy away from absolutely trying to seduce Bokuto who is watching with rapt attention.

This is a thousand times better than any club. Here, he doesn’t need to worry about any unwanted attention. Plus, the only attention he wants is Kiyoomi’s, and he already has that. His alpha is watching him with a fond expression.

However, all it takes is the three omegas grinding on each other a little too sensually for Bokuto and Kiyoomi to make their way over themselves. Honestly, Atsumu is surprised they lasted so long. Hinata doesn’t seem put out by losing his dance partners and just grabs Inunaki instead. He sends Atsumu an impish smile.

Kiyoomi whispers in his ear and leads him out to a balcony. The night air is a bit chilly, making him shiver slightly. Then a warm hand envelopes his own. He turns to his alpha, who gazes at him with endless affection.

“Atsumu, I love you.”

His eyes crinkle as a warmth expands in his chest. “I love ya too, Omi.”

“I want to spend my entire life with you; and I know we have plans to bond, but that’s fallen through once before.” Atsumu furrows his brows, unsure where this is going.

“That wasn’t yer fault.”

“I know, but I just want you to be mine—and I yours—in every way. You have another heat coming up soon, but our synched cycles won’t be until late December at the earliest.” Kiyoomi shuffles his weight on his feet, and his hand begins to feel clammy. He’s talking in hurried bursts, and Atsumu isn’t sure what he’s so worked up about. It’s not anything they haven’t discussed before.

“And I know it’s untraditional,” he continues, “and we haven’t talked about it at all, so I hope you feel the same way.” Then he sucks in a deep breath before kneeling down on one knee and presenting a small velvet box. “Miya Atsumu, will you marry me?”

Atsumu stares and stares—at the diamond ring tucked into the velvet and at Kiyoomi’s face. Of all the things he could have expected tonight, this isn’t one of them. Marriage is a beta thing. Bonding is held at the same level in the eyes of the law, if not higher, so it’s not common for an alpha/omega couple to get married. It’s not necessary. So the fact that Kiyoomi still wants to has him speechless.

The lingering silence causes Kiyoomi to fidget. “Atsumu? Was… this too much?”

“Ya… ya really wanna marry me?”

“I want everything you’ll give me.” Atsumu doesn’t realize he’s crying until Kiyoomi is standing in front of him once again and thumbing away a stray tear. “Hey, it— it’s alright if you don’t want to.”

“No… No I— I mean… Yes! Yes, I’ll marry ya!” He wraps his arms around Kiyoomi’s neck and collapses into him. He stumbles in surprise but quickly catches Atsumu to hold him up, chuckling at his antics.

When Kiyoomi slips the ring onto his finger, it feels surreal. He’s engaged. Holy shit.

Back in the lounge, everyone hoots and hollers when they return. As a small crowd gathers around Atsumu to get a look at the ring, Kiyoomi looks mighty smug for someone who was a nervous wreck not even ten minutes ago. Hinata oohs and aahs over it while Suna tries to snap a picture at the perfect angle.

After a few more drinks, Atsumu is desperate to call it a night—AKA get back to the hotel room so he can jump his fiancé as soon as the door closes behind them. His pheromones must have given him away, as Kiyoomi is expecting the onslaught. However, that doesn’t prevent him from riding the alpha into the early hours of the morning.

There’s a poster of him outside of the major sporting goods store in Umeda. It’s a little strange, not because he’s never been on an advertisement before, but because it’s his first time on an omega advertisement. Kenma had sent him a package with some proofs and free clothes from the shoot. Kiyoomi really liked the leggings.

Overall, it seems to go over well with the public. At his last game, he had several high school-aged omegas come up to him, telling him about how he has helped them decide to pursue sports professionally. Atsumu never thought that he’d be one to invoke this kind of inspiration from the younger generation. Sure, he’s a star athlete, but to be a role model for omegas? Never.

It evokes a feeling in him that he’s never had before. Seeing these young faces shining up at him like… like someone who hung stars in their dark skies when no one else would. It’s almost, dare he say, maternal. What would it be like for his own pups to be looking at him like that?

He shakes the thought away. Slow down there. He’s not even bonded yet.

Then the good news just keeps rolling in as the Olympic team roster is announced just days later.

Japan is going to be a force in the Olympics next year. While Atsumu had no doubt in his mind that he and Kiyoomi would make the team, he’s honestly surprised Suna’s name is absent. Gao and Hyakuzawa are both obvious choices, but it’s strange for there to only be two middle blockers on the roster.

When Atsumu talks to Suna on the phone later that day, he tries to play it off, but Atsumu knows him better than that. He’s disappointed.

“It’s whatever. Now I can watch you all from the comfort of my couch.”

“Ya and I both know that yer ass is gonna be with ‘Samu at the restaurant. Now quit it with yer sass. Ya’ll be out there in 2024.”

Suna snorts. “Right. When I’m 28 and have arthritis creeping up my spine.”

“Like ya would let that stop ya.”

“Hm.” There’s a slight pause, and Atsumu lets Suna take it. He suspects that he’s working on some smartass remark, but what comes of it has no real heat to it. “You’d better medal so that I look good coming onto a winning team.”

Atsumu grins, shifting the phone in his hold. “Ya got it.”

Atsumu feels it as soon as he wakes up. It’s become familiar over the last year. These urges to do things that seem otherwise bizarre. Kiyoomi awakens in a similar state, and it’s interesting to see him properly in pre-rut. His mannerisms greatly please Atsumu’s inner omega.

As he gathers materials for his nest, Kiyoomi is right there, keeping watch. He prowls around, rubbing his wrists over seemingly random surfaces. Atsumu is constantly coated in his scent, not that he minds in the slightest. Thankfully, they’re off right now and don’t have to leave the apartment often. They will definitely be… occupied as the new year rolls in. For now though, they spend their evenings cuddled together on the couch.

The whole process is a far cry from Kiyoomi’s last rut. While he’s not calm per se, he’s not agitated either. If anything, he’s a possessive cuddle monster. His hands are constantly on Atsumu, holding him, caressing him, or feeling him up. In a perfect world, they’d be conserving their energy, but Atsumu can’t deny Kiyoomi. Especially when he himself is just as much of an active participant.

Once the heat and rut hit, Atsumu isn’t sure what to expect. His heats alone aren’t terrible, but he has no baseline to compare Kiyoomi’s ruts to. Then what will it be like when they happen at the same time?

When he asked Hinata about his own experience, he said that it wasn’t all that different from normal except that Kageyama was a beast. He also said that the scents are intense. As long as he doesn’t go into some drunken stupor, it should be fine. Atsumu wants to remember every part of this.

Kiyoomi’s scent is getting stronger. It’s taking a momentous effort to not take the couch cushions and include them into his nest. The scent of his alpha is so potent. If Atsumu thought that he smelled good before, it’s ten-fold now. Seriously, if he could bottle this stuff he’d be a millionaire, but he doesn’t want anyone else to have this scent. No. It belongs to Atsumu—his Omi’s scent.

Atsumu has just gotten out of the shower when Kiyoomi suddenly barges into the bathroom. His shoulders are tensed, and his chest heaves with every flare of his nostrils. Then the scent that he brings. It has slick dripping from Atsumu’s pussy and down his thighs. He stares at the alpha owlishly for a moment as they just eye each other.

“I need to breed you,” Kiyoomi says in that deep, rough voice. The whine Atsumu lets out would be embarrassing in any other situation, but he’s panting as his body turns feverish with need.

“Fuck. Yes! Breed me, alpha.” The words have barely left his mouth before the alpha is on him. He presses Atsumu’s still damp and naked body against the wall, attacking his neck with teeth and tongue.

“Atsu, god— You have no idea what you smell like right now.” Kiyoomi quickly rids himself of his clothes as he presses against Atsumu. “I need to be inside you.”

“C’mon, c’mon. Need ya.” Atsumu hooks one of his legs around Kiyoomi’s hips, opening himself up for his alpha.

He grips onto Atsumu’s thigh and easily pushes his hard cock into the wet heat with a groan. Atsumu’s head thumps against the bathroom wall when he leans back, and his other leg is picked up, allowing Kiyoomi to sink in even deeper.

There’s no preamble. With both of them in their most basal states, nothing more than the sound of skin slapping, Kiyoomi’s grunts and growls, and Atsumu’s whines and moans are exchanged. All he can feel is Kiyoomi. All he can smell is Kiyoomi. All he can think is KiyoomiKiyoomiKiyoomi. And even then, it’s not enough. He needs—

Atsumu wails as Kiyoomi’s teeth sink into his shoulder. He comes, feeling the knot inside of him expand within his throbbing walls. Kiyoomi’s deep groan reverberates through him from where his mouth is still latched on. Clutching onto his alpha, they both come down from their orgasms, starving off the heat for a moment.

“Omi~ ya missed,” Atsumu whines.

“No, I didn’t. I’m not bonding you against the damn bathroom wall.” He swiftly turns with Atsumu in his hold and heads towards the bedroom.

He’s gently lowered onto his nest. Kiyoomi remains above him, beginning to mouth at his mating glands on either side of his neck. The urge to claim and be claimed churns in Atsumu’s gut stronger than it’s ever been. His mouth salivates, dripping with saliva containing the enzymes only produced when one is able to bond another.

Even with Kiyoomi still knotted inside of him, Atsumu’s body flushes, heated with the need to become one with his alpha. It’s like his inner omega knows it’s coming. Tilting his head to the side, he bares his throat fully and rakes his fingernails across Kiyoomi’s shoulder blades.

“Kiyoomi, please… Make me yers.”

As Kiyoomi raises up to look Atsumu in the eyes, it’s the expression on his face that makes Atsumu’s breath hitch. By now, he’s seen several of the alpha’s faces. However, this one could rival them all. There’s not just love or lust there. It’s a look of pure devotion and intense belonging. No other place would either of them feel as safe and at home than here in the other’s arms.

“You already are, Atsumu,” he says in a low voice. “You’re mine.” Then he descends on Atsumu’s chest, kissing and sucking dark spots along his collarbone and around his pecks. “Every part of you, body and soul.”

Atsumu’s walls clench around the deflating knot, arousal curling at the base of his spine. It’s true. Every part of him belongs to Sakusa Kiyoomi. Everything that he is and will become. Now, he just needs it for forever.

“Bond me, Omi.”

He slowly pulls out, making Atsumu whimper. Then he leaves a lingering kiss on his swollen lips and says, “Present for me.”

Atsumu scrambles onto his stomach and lifts himself up onto his hands and knees, sticking his ass in the air for his alpha’s taking. And take he does, grabbing his hips and draping himself over Atsumu’s back as he thrusts inside.

“Ah— Omi!”

“Love you so much, Atsu, my perfect omega.”

He’s already close again as Kiyoomi nips at the gland on the nape of his neck. The pace set is punishing, and Atsumu’s legs tremble with every slam of Kiyoomi’s hips.

“Fuck. I need to see you.” He pulls out and swiftly flips Atsumu on his back before plunging back in, pressing his forming knot into tight heat. The stretch has Atsumu arching his back and moaning. “There you are, my omega. My mate.”

Atsumu leans into the hand caressing his face and looks up through blurry eyes. His heart pounds in his heaving chest. Kiyoomi presses their foreheads together, looking into his eyes as he starts up again. A hand on his waist keeps him grounded as he’s fucked into the mattress. Warm breaths tickle his face.

Tilting his chin up, Atsumu connects their lips in a passionate kiss. Kiyoomi kisses down his jaw until a wet tongue licks and sharp teeth nip at his gland. The grip on Atsumu’s waist is bruising, and he hopes it shows. Each punishing thrust drives into his prostate, drags over his clit. All the sensations together are overwhelming.

“Omi, Omi, Omi—“

There’s white. Bright luminous white that fades to black just as quickly. A phantom warmth runs through his veins, consuming him. Sandalwood. It surrounds him, wrapping him in a cocoon. Atsumu has just enough sense left in him to find the source and bite down.

He’s floating—there in the void, but he’s not scared. It’s here where the spirit resides, his inner omega. Its wispy tendrils reach out and curl around another in the darkness.

Peace. Shelter. Euphoria.

Alpha. Kiyoomi.

Atsumu can feel him. It’s a warm thrum of energy residing in his veins and all the way down to his bones. Bound to the soul.

His normal senses come back to him, and Kiyoomi and he are tangled together. Atsumu purrs into the crook of his neck. There’s a slight tingling sensation deep within him—a pulse almost like a heartbeat, and he knows that it’s Omi. It’s a constant reminder—reassurance—that they’re one and the same.

Kiyoomi is stroking his head, and Atsumu smiles at him, feeling complete bliss. It’s knowing that he will have this for the rest of his life. This is his life. Kiyoomi is his mate. The intense joy bubbling up inside of him releases in tears running down his face.

“Omi, I— I‘m so happy.”

“Me too, Atsu,” he says, thumbing away a tear. “I love you so much, and now no one can ever doubt it.” His dark emerald eyes glisten with his own unshed tears.

“I love ya too, Omi.” They cuddle close together, locked in each other’s embrace.

It’s always been Atsumu and Osamu. Osamu and Atsumu. The Miya twins against the world. Perhaps that hasn’t been completely true for a while though. They picked up Suna along the way, and now, so many others stand alongside them too. It’s his own family or pack, he might say. And he has Kiyoomi. His love, his mate—something that he never dared dream that he’d have and hold dear.

He’s learned what it is to be an omega—to be himself. Though he still struggles with his confidence and loving how he is at times, his support is solid and lifts him out of the pits of darkness that threaten to consume him. They love him for who he is, and that’s all he could ask for.

The heart is a funny thing. Beating thousands upon thousands of times every day, its vitality is unmatched, everchanging in its intensity in both power and feeling. Whether it’s a love that burns brighter than the sun or a yearning to be accepted, Atsumu has learned to follow it in all its forms. His favorite form is that of Sakusa Kiyoomi. He’s finally reached the top of the mountain and is looking at the horizon, though Kiyoomi is no longer in the distance; he’s standing there with him.

Love isn’t static. It evolves as he himself grows. The heart can't be told what to do or how to feel. Atsumu has allowed his omegan instincts to guide him, though tentatively at first. However, his dynamic has yet to lead him astray—so he follows. He’s excited to see where it takes him.

Life is about intuition and listening to what that inner voice says. Because while the world changes, these things don’t lie.

It’s all about dynamics. Dynamics of the heart.
