Chapter Text
The pup was definitely active. It crawled fast and found trouble faster. Exploration was its forte, and Katsuki had never known about so many pup-sized crevices and dangers in his home until it just about found and squeezed into them.
Thankfully, it also wasn’t a crier, even when it did somehow ended up a bit hurt from all of its rummaging. And although Katsuki himself was someone who wept whenever he felt overly frustrated, and Izuku had shown signs of not having a full grasp of his own emotions, it hadn’t shed a single tear in the seven days they’d been here.
It babbled quite a bit, was prone to laughter once it got comfortable enough, and made all types of noises and gleeful sounds even when it was being scolded. It also put away the food like a famished badger.
Holding it quickly came easy and natural because keeping it in his grasp was the most suitable punishment he could think of whenever the pup kept repeating its impish behavior.
Which meant Katsuki was holding it often.
That irked the pup quite a bit, but it was also an excuse to keep the pup in his arms. Squeezing its plump cheek against his whenever it was whining because it couldn’t play in the firepit. Restraining it over his shoulder as he cooked one-handed because it decided to keep ripping pages out of books. Balancing the pup on his shins as he crunched the muscles on his stomach after it overturned a potted plant and rolled around in the dirt.
All that to say, Katsuki would have lost his mind days ago if the pup wasn’t there.
The distractions the pup brought were nothing short of heaven-sent blessings. Chores that ensured Katsuki didn’t linger too long upstairs, where croons and lust-soaked whimpers strived to tempt him down the hall; responsibilities that had his mind focused on changing diapers instead of ruining sheets.
The pup was also a constant reminder that, although it gave Katsuki inexplicable joy and made his chest aflutter with an overwhelming feeling he had never experienced in his whole lifetime before, one toddler was enough work as is. For now.
Whenever it slept was when Katsuki was at his weakest. Even when he’d nose into its soapy and moisturized skin or hair, searching for some sort of relief against the hail that was its dams desperate and anxious calls, it just wasn’t enough. He lost count of the times he swore he was a hair away from cracking, but somehow, whether through willpower or by simply throwing himself outside to breathe for a moment, he never actually did.
Today Izuku had been quiet, or at least, whatever he was doing behind the door had now been greatly muffled.
A part of Katsuki figured that the omega had been sleeping off all of that pent-up adrenaline and energy. Crashing after days of nothing but high-strung vivacity and frustration from an itch that couldn’t be so easily appeased. Rest that Izuku likely needed.
However, the alpha in his muscles was in absolute mourning. Not being able to sate what his body had recognized as his mate for his entire heat had Katsuki miserable once that lucious redolence began to subside and the weight of need in the air began to lift.
The pup didn’t give a flying shit either way.
Or perhaps it did, since from morning until evening it either uncharacteristically clung to him like a vine or would slap at Izuku’s door until Katsuki scooped it back up, nuzzling into its stomach to distract it.
At least bedtime still came easy; handing over its blanket and placing the pup on the side of the bed that it now laid claim to, since the nest had been decimated. Only this time, it wanted to be held, growling until Katsuki finally submitted under its large scaly claws and allowed it to crawl up onto his chest. The pup was pouting until he began rocking with a made-up tune being hummed near his small ear as Izuku had done, and only then did it snuggle in close and drowsily yawn.
It had taken close to a week for the pup to begin trusting him. It spat less and would smile at him with small milk-teeth instead of simply stare and sniff, yet Katsuki was all but used to the idea of fatherhood from the moment he laid eyes on it. He had made his decision to sire when the snow had stamped out the fire, and from then on he had not a single regret.
Half of his genes contributed to a hearty and happy pup. Confident and unafraid, ready to brawl to protect its family, but Katsuki could already tell the cub would be brilliant as it aged and matured. It’d be everything both Katsuki and Izuku were and more.
“You should have a bit of fear in you, though,” Katsuki contemplated aloud as the pup curled its fingers in the short hairs on his neck, its lids drooping and fluttering closed, “there’s monsters out there, you know. Beasts who’d love to carve you up and roast you with a whole fruit shoved in your mouth for garnish.”
He watched as its feet would twitch while his finger stroked along the tiny pads and counted each round little toe.
“But you’re a bigger beast,” Katsuki grinned at the pup. His pup; even Izuku had come to admit, “the most fearsome one of all. That breathes fire and spits flames and eats coal for breakfast and all the other creatures that don’t even come close to its greatness for dinner. Which is why you’re so fat.”
But the pup had drifted along to sleep after having stayed up past its bedtime, content and at full ease on top of his sire’s protective torso.
Katsuki stayed put for a few more countless moments, measuring their breathing and, ultimately, failing to calm his frayed nerves enough to go to bed himself. He needed to sit outside. Hell, perhaps sleep out there if it’d give him some clarity until the morning when he’d hopefully be in a much better mood.
Turning, he slipped the pup down onto the bedding, so very thankful that it was a hard sleeper, but before he could completely break free, he needed to untangle his hair from its hold.
“Do all pups have such strong grips or were you nursing longer than you actually needed to?” Katsuki grumbled as he pried off each finger.
Once he had been released, Katsuki sat on the edge of the bed. Hunched over his lap and dragging his hands down his face, pressing his digits into his all-too awake skin and exhaling through his nose before he pushed himself up.
He closed the door behind him as he toed out into the quiet, bare hallway. Deciding on a quick stop in the washroom where he could splash cold water onto his face and redirect the blood flow away from his groin, which had been nothing but a hindrance for days. Yet, before he could cross the frame, a choking sound from the guest room gave him pause.
As he stood there in the silence of his home, where he could still hear the muffled chorale of cicadas and frogs, the choke of breath gave way to obvious bawling. Katsuki would have thought it nothing but a symptom of the omega quelling its own remaining need, but the hint of something sour in the air had his heart dropping.
In that next moment his feet moved on their own. His knuckles rapping against the heavy wood in a hushed vibrato, only to be seemingly unacknowledged.
The few times he would even see Izuku were in quick glances between exiting and entering the rooms and washrooms. Food was delivered to the door, and the omega hadn’t stepped a single foot down the steps. So when Katsuki had turned the knob and peeked inside the night-tinted room, he was completely besotted.
Pillows on the floor—save for one between his naked thighs— the pelts and sheets strewn about and crumpled up along the bed. His tuft of hair ravelled and wild, and although he was laying on his side, Izuku’s face was hidden by the bedding. Somehow, his messy demeanor appeared gorgeous.
However, the way his shoulders shook from wheezing had Katsuki snapping his attention where it needed to be.
“Izuku,” he called out under his breath before he slid into the room, door closing behind him and truly giving him a taste of the distress the omega was going through, “Izuku, you awake?”
Still no response, so he crept closer, minding all the known creaks of the floorboards to not startle him worse as Katsuki approached the bedside. Now close, he could pick up the feeble murmurs of “no”s and pitched whimpers.
“Izuku?” he harshly whispered as he crouched, his hands reaching out but withdrawing at the last second once he thought better of it, “beastie? What is it? What’s wrong?”
“Off...stop…”
“Oi,” Katsuki called a little louder as he shook the bed instead, to no avail.
“Hurts…” Izuku sniveled as his legs squeezed around the pillow, “ugh…”
He worked his jaw as he scanned from the cushion to Izuku, knowing it was nothing but an object in this realm but perhaps something terrible and very much alive wherever the omega had found himself in. Carefully, Katsuki inched the pillow from his tight hold, ignoring the potent spot of slick as he placed it on the floor, and decidedly began to gently rub his back.
“Oi, beastie, wake up,” his tone was more firm as he warmed the skin that was cold with dry sweat, “come on, Izuku. Kill those bastards again and again. Burn off their hands and freeze off their genitals, make those sons of bitches suffer. ”
His hand drew back when Izuku jolted and his head finally popped up; doll eyes stretched wide beyond his skull, mouth opened as he fought to control his breathing.
He turned about until he landed on Katsuki, whose chest almost hollowed out when the omega initially flinched, nearly scrambling to pull his legs close to his body and drag himself away...until his flared nostrils twitched and his pupils seemed to shrink in on him.
“Katsuki?” he rasped, “wh-what are...what…?”
“You alright?” he asked, not caring if the concern was visibly laced in his voice or not, “you had a nightmare.”
Izuku blinked a few times before he looked over himself. Then he rubbed at his eyes and looked at the shine on his fingers incredulously, “yes…? I don’t know why, I...I ha-haven’t dreamt like that in so long.” He placed his hand over his undoubtedly racing heart, “shit...”
It’d been a while since he had heard him swear.
Katsuki usually wasn’t prone to awkwardness, but at this moment, his mind was going in various directions for plenty of disparaging reasons and he needed to straighten them out so he wouldn’t be so useless.
Eventually, he palmed at the side of his neck and stiffly patted the bed. Izuku snapped to the sound, but after realizing what Katsuki meant, his shoulders eventually slackened and he gave an uneasy nod.
Easing onto the bed, lifting his legs straight out before him, Katsuki sat against the headboard with his arms loose at his sides. Izuku hadn’t moved over, so he could feel his sleep-frozen body beginning to warm-up as the omega pulled his feet in close.
“Do you...regret what you did?” Katsuki ultimately asked. Izuku has had that nightmare before. Repeated dreams held meaning. At least, that was what the elders and some books said. So Katsuki treaded the previously unspoken ground, hoping that what he asked was the right thing for him to hear.
“Killing that rattlesnake? No.” Izuku shook his head and straightened out his back as his hands fell to his sides. Some of his fingers landed on Katsuki’s, but neither of them moved away, “...I’d do it again and again to whoever it was that so happened to be there that night. But I was in the capital for three long summers, and many things happened within that time. I don’t know if I can ever forget them.”
Katsuki swallowed because his throat didn’t want him to say what the storm in his mind was rumbling for him to: “...Maybe I remind you of those things.”
“No,” he answered without hesitation, and when Katsuki faced him, those opulent brows were furrowed with sincerity and the wet gloss over his eyes made his words seem more momentous, “not at all. I had told you before, you bear resemblance to that bastard, but you are nothing like him. You’re not like any of them. If I had dreamt of those events, it isn’t because of you. It won’t ever be because of you.”
The smoke cleared between his ears and became a clear mist that drafted out as respite on his shoulders.
“But you were here when I woke up, so that means...Wa-was I loud?” he whispered as his hand hovered over his mouth with sudden concern, “did I wake you and the pup? I am so sorry, I know he can be a handful if his sleep gets interrupted, but I think the heat is starting to fade, s-so if you want to rest, I can bring him in here and—”
“I was already up,” he reassured, “I just so happened to hear you on the way to the washroom, but your scent gave you away.”
“So you...came in here just to check on me?”
“I came in because the only reason anyone should be crying in this house should be because I made them and shit that is not what I meant.”
Izuku stared at him as his hand lowered, revealing a small smile beginning to crack his soft features before breaking out into a short little laugh. He dried his damp cheeks with his arm while Katsuki tried to overcome his faux pas by grinding his teeth and focusing on his toes while he buried them in the sheets.
“Ah, Katsuki…” he sighed as his head fell back against the headboard with his lips shrinking into a taut line, “you are so amazing. I wish I could give—I wish I could even do something for you to show my gratitude for everything you’ve done for us.”
He raised his battle-worn hands before tightening them into firm fists—“even from the start, you were helping me. You pulled a stranger from a blizzard and bandaged my wounds. You offered your food, offered your bed. Maybe there were other motives at the time when we were under those influences, but knowing who you are now, you...you are a lot more kind than I think you are even aware of.”
Katsuki took in a bout of air, resting it on his tongue with a slight tilt of his head as he looked aside.
“No, I’m not.”
“You must be,” Izuku argued. His eyes hardened with resolve as they bore into the side of Katsuki’s face with enough heat to rival the color of his own, “I wouldn’t be alive if it were not for you. I didn’t want to admit it at first, having relied on myself so long that at some point I became my own god, answering only to myself, but I can’t deny the truth for long. From then to now, you’ve been a ray of light on my life. No matter how we started out, I’m very fortunate to have met you, Katsuki.”
It was silent while they sat in the spirit of his words. Izuku believing everything he said with all the confidence that someone who actively chooses to live off the land with a toddler would have.
He was a forest filled with hazards around every bend, yet all the beauty the earth could offer and naturally conceive. A harmony of sharp canines and doe eyes, sweet hums and poisonous threats. A creature Katsuki never met before and a man he couldn’t imagine being without.
Katsuki eventually snorted and sucked on his teeth.
“You say all that aloud,” he muttered as he met Izuku’s glare with an amused one of his own, “without knowing that his entire week, I’ve been wanting nothing but to fuck you open and have you spilling over with my seed. That my dick’s been agonizing these past few days because I know the warmth you hold between your legs and miss it terribly. And actually, sitting here, I’ve done nothing but fill my lungs with whatever remains of your scent as you’ve calmed down from remembering something awful because that’s all I can do. Breathe you in and breathe you out and try not to imagine too much. Or I’d break you otherwise in more ways than I’d like.”
That spring-valley resolute stare began to wane while a deep flush darkened his freckled cheeks. The hand on top of his eased into a closed fist, but he didn’t slant away. Even when the savory ginger essence deepened, heady and growing in volume without his consent, he only pressed his thighs together as though he had smelled it as well and wanted to cap it off.
“No, I don’t think I’m very kind at all,” Katsuki chuckled a bit solemnly, “I don’t know if I ever can be.”
“But you haven’t,” Izuku piped up with an audible swallow.
“...Haven’t what?”
“You haven’t done any of those things you said you wanted to do,” he explained as he looked askance with his feet smoothing to and fro over the bedding, “thinking one thing but doing the other because you know it’s for the better, that just...proves my point more, doesn’t it?”
He blinked and looked down at their hands when a marred finger looped around one of his.
“Besides, those people who probably had similar desires about me and did act out on them, I never wanted them. But with you, it’s...different.”
“Different?”
Izuku nodded as his legs flattened and crossed, “you said you had difficulties trying not to imagine things. I, um, had trouble, too.”
Katsuki’s brows eased up his forehead.
“Even before I had gone in heat, I still had the same troubles...funny enough.”
Working his jaw as warmth flowed down into his belly, Katsuki leaned into the omega’s space, staring intently at the twitch of his long black lashes until Izuku looked up at him. Spring-bound irises skirting all over Katsuki’s face then pausing on his mouth when he anxiously wet his lips.
“So what are you saying?”
Izuku’s chin tipped back a bit, tightening his throat while his hand made its way into Katsuki’s, “I’m saying that you’ve been doing what I want. But now, I want to know what it is that you want.”
He continued to press forward and Izuku inhaled a shaky breath as he began to sink onto the bed below until Katsuki was partly hovering over the omega with his hands on either side of his head.
“You. Obviously,” he replied while the ghost of their lips and the tips of their noses brushed over each other, eyes naturally hooding from the intimate proximity.
“In whatever capacity you want to give, I want you. I want you laughing at my dumb shit and confronting me on my bullshit. I want you to have time to hunt again, and I want you to unwind in the tub you like so much. I want us to fight and chase each other like animals and I want us to sleep in the same bed like mates. I also want our damn pup to stop trying to put his paws in the kiln—”
And then he was muffled by trembling yet steady lips. Pushing up onto his mouth until Katsuki’s eyes fell shut and he pushed back, meeting him halfway while his heart paced and drummed wildly in his ears so that was all he could hear.
When Izuku broke away, it was too soon, and the omega rectified the mistake. Kissing him again with more urgency and clarity and Katsuki cradled his head in his hands, keeping him there longer, kissing him hard enough to have those sharp nails drag along his bare chest and his lungs failing to fill properly.
Soon Izuku was moving, pivoting until his body was completely beneath his, and then those tempestuous legs were hooking over his back and Katsuki let himself tumble in between. The omega gasped at the friction, his claws raking over his shoulders when the weight of his clothed cock fell against the damp lips.
Katsuki could already feel that nostalgic heat searing through his pants as he vigorously rubbed their sex together, head tilting to the side so he could lick into the omega’s moaning mouth. Their hungry forms quickly finding a familiar rhythm, as if it had been choreographed from the start as he humped and dampened the front of his crotch.
But Katsuki wanted something a bit more unfamiliar. He started mouthing over Izuku’s cheek, down his jaw, lower until he was tasting the dried sweat in the hollow of his neck, on his perked nipples, and down in the slight dips of his stomach, following that cloying musk below his navel.
He nipped at the stretch marks on his hips and his thighs, his hands outstretched and kneading the firm mounds on his chest while Izuku panted and squirmed beneath them. He was reaching for Katsuki, tugging on his forearms to pull him back up, but he was lulled by spice and ample thighs, nosing into the short scratchy patch of hair where it had also been trimmed to find peace from the heat. Filling his chest and his mind with nothing but gluttonous thoughts and greedy ideas.
“Katsuki,” he whined when Katsuki pulled back his arms to caress over his shape; over his ribs, his sides and the width of his hips until he had a hold of his thighs, “wha-what are you…?”
They parted easily even with the caution in his tone, and Katsuki’s fingers pressed into the hard muscle on his legs as he watched slick ooze out of his swollen hole where Izuku had no doubt been shoving fingers into all week, trying to reach depths that Katsuki knew he easily could with one stroke.
He was so ruddy and wet with only a bit of dry-humping, even with the heat at its end, yet he still smelled decadent. Thick, syrupy herbs and a thin layer of sweetness that could have been pluming off of Katsuki and adding to Izuku’s own scent, but regardless, the combination made his chops drip and his loins alight.
He pressed flat on his stomach and kept those legs splayed as he lapped at the slick along his inner thigh, groaning or growling or some feral mixture of both from the lavish taste. His tongue trailing over to a parted lip where he kissed and buried himself with deep inhales, varnishing his face in must and slick as it smeared over his nose and cheeks and causing the omega to flinch and tremble with a small mewl.
“Wh-wh—” Izuku faltered as he tried to squeeze his knees shut, but Katsuki was clenching them hard enough to bruise, “wait, wait, Katsukiii—!”
With a long wet drag of his tongue over his hot entrance, Izuku had muffled his resulting shriek with his hand but Katsuki wasn’t going to give him time to think about his volume. He licked the omega open, dragging the width of his tongue back and forth between the sloppy lips and over that hard little bud he used to toy with so much before. He’d never done something like this, but the urge to finally meet the alluring fragrance at the source had chained him down and dragged him down to its abyss.
“Ohh, oh my gods what are you do-ing?” Izuku brokenly keened into his hand as his hips involuntarily rolled up into his mouth, “I haven’t—haah—it feels—”
“Bad?” Katsuki asked as he pulled away, swallowing what was on his tongue with the gratification of a well-fed feline.
“No!” he shook his head as he fisted at the pelts, legs widening while his desperate hips swiveled to find that pleasure again, “it was so good, please, Katsuki, can you please?”
As if he’d say no to those dewy eyes.
Katsuki dived back in with fervor, tonguing from his ass to the bud in long stripes before he spread the flushed folds with his thumbs. His teeth grazed over the sensitive nub before suckling and flicking over it, which made Izuku buck onto his face and choke on a wanton sob. He gave the omega some solace as he lapped lower, slurping at his twitching hole until his tongue slipped into its smoldering heat, rolling his eyes and pulling a moan from his throat as slick poured into his mouth from the intrusion.
Clasping his hands around the tops of his thighs to keep him still, Katsuki wriggled deeper inside, jaw widening until it twinged so he could embed himself into Izuku’s pussy. Splitting him open with his tongue and sucking on his lips until the omega was a writhing mess of cries and bawls.
Katsuki opened his eyes to watch as the omega's head tossed side to side, the occasional arch of his spine, the pounding fist and the way his fangs sank into his knuckles with real, fat, salty tears glistening down his cheeks and heaving chest.
He’d say his name, too. Cried out “Katsuki” all wrecked and ruined when his large fingers prodded inside along his tongue, stretching the soft muscle and pulling out more of that wet pheromone for him to devour because he couldn’t get enough. He was parched and wanted to feed off of his omega, take everything he gave until he decided Katsuki was full enough.
The hand tugging at his scalp only urged him on. At first, it was gentle, unsure pets before quickly descending into sharp pulls and a heavy palm tamping down the back of his head so he’d stay down while “yes” “yes” “yes” filled his ears and made him hump down onto the bed to relieve the throbbing, seeping erection in his pants.
It was too good. He tasted so good that Katsuki had slick and drool dribbling from his chin and was moaning from the copious amount spilling forth. There was a twist in his gut as if he were about to cum at any moment just from this, completely untouched, but he refused. Not yet. Not this way. Not tonight, at least.
“I’m so close—I’m so close, Katsuki, please, please—” Izuku pleaded around his choked-up tears as his waist stuttered and both of his hands pulled at his roots, accent dripping into his speech and thickening it to make it sound near-intelligible.
But then Katsuki was pulling back in a rush, pushing onto the backs of his knees and out of the trappings of his thighs, a devastated wail from Izuku’s clenched teeth from the absence as Katsuki hurriedly heaved himself back up. He smothered his buzzing lips against the omega’s, swallowing down his fraught-filled sobs until he grew feeling back into his tongue, letting him get a taste of himself and hopefully realizing how hard it was for Katsuki to leave.
“Don’t cum yet,” Katsuki growled against his mouth as he caged Izuku’s head with an arm while the other wrested down his pants until he could drag his heavy, leaking cock free. Shakily sighing while he coated it in pre and slick from his fingers, finally being able to touch himself after so long, “don’t cum yet—”
Izuku gasped so sharply that Katsuki swore he took some of his own breath away once he started pushing the head in. Sinking into his drenched, plush hole and hissing through his canines at the way he stretched around him. The arm that held up his weight shook as Katsuki kept going almost painfully slow, working him open so he could fill him in one thrust, inching in further and further while the kindle inside made sweat sprout at his hairline and above his lip.
Izuku wept when Katsuki was seated completely inside, grinding into his guts with shallow thrusts that had the omega’s hips and legs lifting off the bed. His head rolled back into the cusp of Katsuki’s hands, slack-jawed with muted moans as tears rolled over his fingers.
“Fuck,” Katsuki panted as he tried to pull out but hardly managed an inch as the tight, soaking heat squeezed him like a vice and sucked him in deeper. His cock dragged along the rippling walls until it was a quarter way out with slick following along in hot beads, then he slammed it all back in, watching as the white took over Izuku’s eyes and that was it. He was going to build him up like a church with stained glass walls.
The slide was easier as he kept thrusting, reshaping his hole until his soul returned to him and when it did, Izuku clawed down Katsuki’s sides and ass, openly sobbing along with the harsh, wet slaps of skin against skin.
It somehow was better than before. More intimate. More stroking and fondling and with a comfort Katsuki had never quite experienced with anyone else. He didn’t want to think Izuku’s body was made for his own, but he just felt so right; could take his size and fit his waist perfectly between the spread of his legs, the right height to have each rough plunge sway his entire body and inflate Katsuki’s ego, could squeeze his hands around the small of his waist and almost touch his fingers, strong thick legs that could press into his back so he could continuing fucking him deep. Pretty moans and long lashes to gather up the rivers of tears from a lay too good. So perfect in body and spirit.
Izuku was all he wanted. He was all he needed.
Bowing his head, Katsuki kissed the streams from his cheeks, shifting to his lips when Izuku would tilt his head and whine. Tongues and lips and teeth molding and scraping over each other in a mess of affection and lust and heat.
“So fucking gorgeous,” he crookedly grinned as Izuku crooned for him, his rough palms smoothing over Katsuki’s arms and hands while his pelvis rammed against the omega’s thighs hard enough to make his swollen lips wobble with the rest of his rocking body, “feels so damn tight, gods, you’re killing me. Would you let me die like this? Balls deep in your pussy? Say yes, please say yes, shit, shit, let me go, let me go...”
Izuku breathlessly laughed into his shoulder as he pulled him close, throwing his legs around his waist and cradling his head with his hand as Katsuki nipped and sucked below his ear, “ah, I-I don’t need any more bount-bounties...”
“Well, I’m fucking, about to cum,” he grunted as he reached back and folded one of his thick legs against his torso, angling the tip of his dick to bruise that sweet spot that had the omega quaking and his toes curling, “and if I’m damned, I’m damned.”
With that Katsuki’s pace grew brutal and erratic. His breath shortening as everything below his navel began to wind and tighten. He had already been on the brink before he even got his dick wet, and had assumed he’d cum as soon as the tip began to spread his lips apart, but he’d manage to last longer than expected. His instincts fighting to ensure that his mate was taken care of first, that the omega would orgasm after making do with nothing but pillows and his own hands for days.
Izuku was bawling against his skin while he held onto his back, his thighs compressing him so close that his lower back began to grow sore but he was almost there and he wasn’t about to pause just so his spine wouldn’t snap. He needed to keep going, needed to hear Izuku scream and feel the clench around his cock when he climaxed around him.
“There, there, there, Katsuki! Fuck! I’m gonna cum, I’m gonna cum—”
And Izuku certainly did as he clamped down around Katsuki’s throat with sharp, pointed fangs. Cumming in waves with hard shudders, groaning into his aching flesh as drool dripped onto Katsuki’s shoulder and fuck it caught him so off-guard that a shattered cry left his own throat as he pulled out, spurting rope after thick white rope into his palm as his hips jerked and his fingers pumped at the veiny shaft until nothing more would come out.
He was panting when Izuku let go of him, reeling from the scolding wound on his shoulder and the wreckage of his orgasm.
He didn’t collapse right away, using the bit of his strength to stare down at the omega who was just as demolished as he was. Though he was probably a much more stunning sight, with his blush from his ears to his chest and his lips plush and wet with spit and a bit of what was likely blood.
Katsuki finally wiped the stickiness off his hand onto the pelt, and when Izuku reached up for him, he caught his wrists.
“You…” he puffed, “...you bit me.”
“W-well, you pulled out,” he countered with his own labored breaths.
“Yeah, ‘cause I’m not risking shit because you just got off your heat and that dragonling of ours is a menace but that isn’t the point.” Katsuki shook his arms for emphasis, “you fucking bit me! And not in self-defense!”
“I-I was—I only—I got caught up in the moment, alright!” He stammered as he tried to cover his reddening face with his hands, “It happens to people all the time! You’ve even done it to me before!”
“So you didn’t actually want to mark me up as yours, huh?” Katsuki wickedly grinned, sweat rolling down the side of his face and tickling the fuzz there but he didn’t want to move or get distracted by anything else, “you’re shit at lying, remember?”
“...I mean,” Izuku mumbled, “...ye-yes, but not as carelessly as I just did.”
“Oh?” His grin grew wider as he let go of his wrists so he could snake his arms around his back and turn them on their sides, trying to nose under his hands so he could get to his embarrassed face, “so you had a plan to do it eventually?”
After a pause, there was a small nod and Katsuki snorted. The aftershocks of his climax began to wash over his bones and turn his body to mush after going too long without any sort of relief, but the omega was doing the same thing to his mind.
He kissed the exposed part of Izuku’s forehead.
“Thanks, shitty beastie.”
There was some muttering in response which Katsuki was unable to hear, so he moved one of his hands away to uncover a flushed omega with his eyes pinched shut, refusing to look at Katsuki when he asked to repeat whatever he said.
“Bite me too,” Izuku whispered.
To imprint one’s teeth into their partner was what many considered a desire that came from long ago, back when they were nothing but beasts and couldn’t use words to express themselves. With time, it faded from tradition, to history, and back to tradition again. Even so, it’s something that lingered in the back of Katsuki’s mind. Deep-rooted and echoing but it wasn’t necessary to feel satisfied or connected in the end. It didn’t hold any personal meaning to him, but it still did for some.
Like Izuku.
“I…” Katsuki chuckled in disbelief as he glanced from his neck to his face as Izuku’s eyes creaked open, “...you actually want me to?”
He nodded again, more sure this time.
“May I know why?”
“I want us to be in each other’s lives. All three of us,” he said as he lowered his arms and tilted his head to expose the plane of sweaty, ginger-soaked, olive-toned skin, “...it’s what we all want.”
Katsuki swallowed down his heart once he digested the words, a smile breaking out across his face as he pecked all along the warm skin and compressed the smaller frame within his arms, a hum of gratification and euphoria igniting in his blood and making him feel on top of those very mountains near where they first met those many illustrious seasons ago.
“Alright,” he replied with another kiss to Izuku’s own stupid grinning lips, “but then we need to go back into my room because if the pup wakes and finds me in here, I’m certain he’d smother me in my sleep.”
With another more eager nod, Izuku closed his eyes, a smile still glued onto his face as Katsuki turned to his neck. He opened up his jaw, his fangs feeling wide and sharp in his mouth, and sank his teeth into tough sinew and soft skin until he tasted iron.

“Ho, Katsuki!” Eijiro waved as he and Denki approached with big friendly grins on their faces. Once they were close enough, they each grabbed a bag off the ground and handed them to Katsuki who grunted out his appreciation, “what is this? Why didn’t you tell us you were going somewhere? We could have helped pack all of this for you.”
Katsuki clicked his tongue as he secured a jug of water and dried off any spillage on his vest.
“And why do you have two horses?” Denki asked skeptically as he reached up to scratch at the mare’s broad neck, “you don’t have that much stuff. It’s more than usual, but not enough for two rides.”
“Asks too many questions,” Katsuki grumbled as he lifted and loaded the last bag on top of the saddle and grabbed the net to tie and hold the short stack down, “just know I’ll be back in the spring.”
“Alright, but you better write us! Though, are you visiting your parents or something?” the toothy alpha inquired as he held his hips in contemplation, “and didn’t you already go during the early spring? Though it is fall now. I suppose it has been a while. I bet your mother was writing nothing but swears in her last letter, eh?”
“You know what else has been a while? Us hanging out!” Denki chimed in as he rooted around in his pockets until he pulled out a few sugar cubes, to which Katsuki squinted at because neither of them owned a horse or drank tea to regularly carry sugar cubes for, ”where have you been, good sir? Either you’re stuck in the house snubbing us, or you’re out in the woods snubbing us.”
“Was I not in your home beating your hides in checkers hardly a week ago?” Katsuki retorted as he pulled and tightened the final large knot in a series of smaller knots that restrained all their items to the horses.
“Sure. Perhaps. You may have a point but—”
“I do have a point, and that point is that you’re both as needy as the need to shit,” he huffed as he surveyed everything, walking around the large hooved beasts as he wiped the perspiration from his brow, “I told you I’ve been busy. I got things to take care of and sort out.”
“Right, and uh, speaking of “sorting out” and “things”,” Eijiro had loudly cleared his throat, clapping his hands together and pressing his thumbs to his nose as he slightly bowed his head and deeply inhaled, “listen, we truly try not to pry and nose into your business because we know you don’t like it and that you’ll eventually tell us what is going on when you are able to or want to, but lately there’s been a lot of hearsay around the village about you purchasing “certain items” that you normally wouldn’t purchase for the sole reason of just having them in your house for decoration or anything and I really am not trying to pry but you have to let us know if the rumors are false because there is just no feasible way you actually—”
“HAAAAH?” Katsuki dug his finger into his ear from the rush of words slamming into them, an annoyed curl on his lip because the sheriffs of Dunce Town could have came at any other time but just had to pick the moment he’s at his busiest, “get to it already, Moron-jiro!”
“Agh!” Denki gripped his long bangs and tugged, “Eiji and I want to know if it’s true that you have a pu—Oh, gods abound!”
They both just about shrieked as well as jumped out of their feeble skins when heavy panting and fuming, excited ginger perforated the air from the entryway of the house.
Katsuki had looked behind him where they had been staring at, finding Izuku suddenly there with his summer clothing on, even though he’d been told multiple times to wear warmer fabrics. The shirt collar and the bottom of his sleeves a darker shade than the rest from what he could only assume was from the blood dripping down his uncapped maw and chin in addition to the four dead rabbits he had in his hands.
Those bright verdant eyes flicked from the stunned pair over to Katsuki who was grimacing with his pulse throbbing on his temple.
“Where’s the baby?” Izuku asked with his teeth surprisingly white and glistening.
“Where in the freezing layers of hell have you been?!” Katsuki barked out instead.
“I told you I was getting fresh meat for the trip,” he meekly answered as he lifted a handful of rabbit proudly in the air, “and then I had forgotten that you were sharpening my blade still so I had to—”
“Alright, alright! You’re getting blood all over the wood, shitty beastie! Gods, look at you, you’re filthy! You’re fortunate I already drew the bath or I’d make you sit on that horse until the next stop.”
“Thank you! Oh, and don’t worry, I’ll clean the floors, I’m getting much better at it and can do it really quick now, I’ll show you,” he declared with a determined grin as he placed the rabbits outside of the front door, “now, is the pup in his crib? I picked some bright leaves for him to play with and some berries and nuts to snack on when he gets hungry.”
The omega was bounding off up the steps before Katsuki could even answer, leaving him huffing and grabbing the caught game where the necks had been torn into and broken. At least the blood was at least mostly drained. How Izuku had always managed to catch one of the skittish, quickest creatures on land was beyond Katsuki, but it did always come in handy for quick meals.
When he turned around with his head shaking, the alpha and beta were both stammering out the beginnings of what sounded like questions but were each having trouble trying to pick what to either inquire about first or point out.
“Who was...what, uh...was?” Eijiro had an easier time forming his words as the duo no doubt heard Izuku’s loud coos and praises and the pup’s bubbling laughter coming from Katsuki’s top floor, “...what was that?”
Katsuki shrugged with a growing smirk.
“Midoriya Izuku from the southern wilds, which is where we’ll be heading for a little visit,” he preened with his chest rising, “and my children’s dam.”
They both turned to each other before facing Katsuki again with wide bug-eyes and the shape of their mouths in permanent “o”s.
“Wait, hold on, hold on,” Denki blinked, “Chil...dren?!”
