Chapter Text

It's not that he was hiding it.

It just never came up?

U.A. is a pretty exciting AND exhausting school to go to, after all. Either the class was hype about fighting an actual Pro Hero, or they were wiped from fighting an actual Pro Hero.

Plus, there was the whole unspoken rule of the locker room. 

Don't look at your classmates dicks.

Everyone tried their best to abide by the rule as smoothly as they could, and mostly it worked out. 

Except when it didn't.

"Where's your dick, bro?"

The voice of Kaminari, horrified, echoed throughout the locker rooms after their last class of the day, causing at least half the people there to glance over at him curiously. 

But he wasn't looking at them. 

He was looking at Kirishima. 

Or rather in between Kirishima's legs.

Kirishima's lips twitched, glancing up at his friend.

"What do you mean?"

"Oh my god, your dick is gone," Sero gasped, almost dropping his towel in shock.

The redhead rolled his eyes, his own towel rubbing over the smooth space between his legs where his sex should be.

"WHO TOOK YOUR DICK, BRO??"

Kirishima swats at the wailing blond, rolling his eyes. "No one took my dicks, bro! They're just not...sticking out like yours is."

"I'm sorry, did you just say 'dicks' as in plural?" Shinsou asks from across the way, towel wrapped around his waist.

"Yeah?"

"Wild you claim to have multiple dicks when I see exactly zero of them between your legs."

"That's because they're hidden. Or rather, they're retracted."

"Curfew is in an hour," Todoroki commented as he passed by, already dressed.

No one paid attention.

"You really want to know?"

"Yes?? Considering that everything I know is now a lie, I would greatly appreciate knowing," Kaminari replies.

Kirishima sighs, tugging a pair of underwear on under his t-shirt. 

"Okay. So you know how my mom has a rock based Quirk, right?"

The people still paying attention nod, while everyone else commits themselves to finishing getting dressed and leaving.

"Well, I was actually born with my mama's Quirk, too."

Deku, who's still struggling to pull his shirt over his ripped chest, pauses to gawk him.

"Two Quirks??"

Kirishima laughs merrily. "Well, one and a half! Y'see, my mama's Quirk is shark based, and some of those characteristics passed on to me."

"Like your teeth!" Sero says suddenly, striking his palm with his fist in realization. 

"Exactly!"

"Bro, I always wondered about that! I thought you filed them," Kaminari says in amazement.

"Nope! 100% natural."

"What does that have to do with your dick, though?" Shinsou asks in confusion.

"I would assume that Kirishima's genitalia are shark based," Iida says behind them.

"Sharks actually have two dicks that are known as claspers. And when not in use, they are hidden inside the body behind a small opening."

"Whooooa," Kaminari breathed. "That's so weird and cool!"

"Can we see?" Sero asked.

"See...my dicks?"

"No, see your collection of weights. Yes, your dicks!"

"I'm also pretty interested," Shinsou said, followed by several murmurs of agreement.

And Kirishima isn't exactly shy, but he definitely feels a little scrutinized with everyone's eyes suddenly on him.

The sound of a locker door slamming shut startles them all. 

Bakugou is standing behind it, looking pissed off. 

"Oi, stop being fucking weird," he growls, picking his bag up off the floor. "You're really gonna surround him and ask to see his junk? Fucking perverts."

"I was just curious," Kaminari whines, only to squawk as Bakugou kicks him none too gently in the back of the leg. 

"Whatever. Be perverts later. It's almost curfew, and if you extras don't get a move on, you're not gonna get dinner."

Those are the magic words.

Suddenly all the boys are scrambling to get dressed, not looking forward to going hungry for the night if they miss dinner. 

In a matter of seconds, the two male's are alone. 

"...Thanks," Kirishima mutters when he's sure everyone has gone.

Bakugou just grunts.

His brow is furrowed and he's twisting the strap of his bag roughly, which is Bakugou™ for 'I want to say something, but I'm not sure how'.

"What's up, bro?" Kirishima asks. 

The blond mumbled something incomprehensible, and Kirishima has to strain his ears to hear him.

"Come again?"

"I...wanna see," Bakugou mumbles softly, staring hard at the ground. "If it's okay..."

Kirishima desperately stomps down the flare of arousal in his gut from his best friend and crush asking to see his dicks. 

"O-oh worm?"

Brain, what the absolute fuck-

Katsuki stares at him for a few seconds before snorting loudly, his eyes rolling. 

"You're such a fucking dumbass," he muttered, but his mouth is twitching into a small smile, and his shoulders are relaxing, and holy shit Brain, you might actually be redeemable.

Kirishima tosses out his own awkward laugh, pulling on a pair of basketball shorts and finally closing his locker.

"I mean...I don't mind if it's just you, bro," he says hesitantly as they head towards the exit. "But why do you wanna see?"

Bakugou suddenly flushes, and he shrugs, staring down at the floor. 

"I'm just interested okay! Is that a problem??"

"What? No! No problem! No problem at all!" He hurriedly assures him, slapping him on the back a little more roughly than he intended.

"You're welcome to look at my dicks anytime!"

"Ahem."

They freeze, looking up into the tired eyes of Aizawa, who was giving them very unimpressed looks. 

"I would like to remind you that you're in public, and firmly ask you keep that kind of talk in the bedroom."

Neither of them are looking at him as they mumble a quick "Yes, sir!" and shuffle past, dark eyes watching them the entire way.

It's quiet now, both of them sufficiently embarrassed, but that doesn't stop Kirishima from gently grabbing Bakugou's wrist when the blond heads to his room.

"Hey, um, i-if you really wanna see, come to my room later tonight after everyone is asleep," he mumbles, trying to ignore the scorching blush on his cheeks. 

Bakugou stares at him, brows furrowed.

"Are you sure?"

And he's not sure.

He's scared. He's gonna be showing someone one of his most private places. A place that he wasn't even comfortable with until he came to U.A. and became more confident in himself. 

But this isn't just someone. 

It's Bakugou.

Bakugou would never judge him.

He looked up, red meeting red in an open, unrelenting stare of confidence. 

"I trust you."

Some kind of emotion passes over the blond's face, too quick for him to properly catch. 

It could have been love, but Kirishima knew that was him projecting his own feelings.

Bakugou nods, staring down at the floor again as he slowly pulls his arm free of the redhead's grip. 

"Tonight, then," he says, and it's quiet, like a secret for just the two of them. 

"Tonight."

Chapter Text

As soon as Bakugou gets back to his room, he buries his face into a pillow and starts screaming. 

He can't believe he just did that. 

Holy shit, he can't believe he just did that. 

"I'm gonna see Kirishima's dick," he whispers into his sheets, heat unfurling in his gut.

HIS DICKS.

PLURAL. 

He groans softly he presses his dick against his bed, already panting from the idea alone. 

He had been gobsmacked when the conversation in the locker room suddenly turned to Kirishima's dick, or lack thereof.

Of course, HE knew that Kirishima didn't have a dick. He'd always known. 

The object of his affections, changing only a few feet away from his eyes?

Yeah, he fucking looked, so what?

But he never knew why Kirishima didn't have a dick.

And now he did know, and he was gonna see them later tonight. 

"Holy fuck," he whispers into the empty room, shoving a hand down his pants to wrap around his already rock hard erection.

A shudder runs down his spine and he bites his pillow, muffling his noises poorly as he swirls his thumb around the head before sliding firmly down the pulsing vein.

It doesn't take him long to cum, his imagination taking the info he had and running wild with it.

Kirishima, spread out against the bed, two dicks hard and glistening between his legs. 

Kirishima on all fours, dicks bobbing in the air. 

Kirishima, pressing both of his dicks together and jerking them slowly up and down. 

Kirishima not having dicks, but tentacles.

He would never admit that this image was the one to make him cum the hardest he'd ever cum in his life, biting harshly down on the pillow to muffle his whine as streaks of white paint his stomach and the bottom of his shirt that he had hastily tugged out of the way earlier.

He lays there for a while, trying to get his breath back, before heaving himself up with a small grunt. 

He's supposed to be going to Kirishima's soon, and it's better to wipe away the cum now, while it's still somewhat wet before he goes.

And change his shirt.

Grimacing, he tugs the soiled fabric over his head and grabs a half empty water bottle from his desk, pouring it over a section of the shirt and using it to wipe himself down before throwing the whole bundle in the trash.

He can get another shirt.

What he can't get is another chance like this. 

Grabbing another shirt from the closet, he tugs it on and slips into the darkened hallway, trying to be as quiet as possible so that no one will wake up and hear him, then panic.

They'll call Aizawa, and accuse him of being a LoV member there to blow up the school, and Aizawa will call All Might, and he'll come and kick his ass and then everyone will come outside and see, and he'll have to explain that he only wanted to see Kirishima's dick and-

Admittedly, he's probably a little stressed about the whole situation.

He sucks in a deep breath, trying to calm his erratic heartbeat as he tiptoes to Kirishima's room.

And everything is fine. There are no alarms. 

He's almost there. He's gonna make it. He's-

"Ahem."

-Really wishing that it was possible for the floor to open up and swallow him whole.

Bakugou freezes, not even turning to look at his teacher standing behind him. 

"Aizawa sensei."

"Bakugou. Headed to Kirishima's room, I'm assuming?"

He's on fire with embarrassment.

"...Yes."

He hears a barely restrained snort and has to remind himself that blasting a teacher in the face would probably be bad for his reputation."

"I suggest maybe next time, you get there ahead of time instead of sneaking out after curfew."

"...Yes, sir."

"You're free to go. And please, mind the volume. There are people actually trying to sleep."

He sprints the rest of the way to Kirishima's door, knocking rapidly until it opens.

"Bakugou, wh-"

"Shhh!" He hisses, slipping into the room and pushing the door shut.

Chapter Text

He locks it immediately after it closes and leans his forehead against the cool wood, trying to calm his rapidly beating heart. 

"Bakugou?"

"I just got caught by Aizawa again," he said quietly. "He said to not be loud about whatever we're doing because people are sleeping."

Kirishima chokes on a laugh and it comes out as some sort of weird, drawn out wheeze. 

"Holy shit, are you serious?"

"Fuck, it was so embarrassing. I think it was worse because he caught us earlier."

Earlier.

When Kirishima said he could see his dick(s).

And fuck, suddenly the thought of his teacher is flying completely out of his mind and he's trying to will away his sudden half chub, perking up in his shorts.

He peeks over his shoulder to where Kirishima is standing, staring at the floor, face as red as his hair.

"S-so..."

Kirishima swallows, his hands clenching and unclenching repeatedly. 

He's so cute. 

Bakugou swallows down his sudden need to kiss those flushed lips and turns, crossing his arms over his chest to stifle the urge to reach out, take him into his arms.

"Are you ready?"

Fuck, he's so ready. 

He can't bring himself to speak though, voice stuck in his throat, so he nods a couple of time instead. 

Kirishima takes a deep breath, steeling himself as he shoves his pants down and off, leaving him completely bare.

And holy fuck, Bakugou is just noticing that Kirishima didn't have on a shirt, he's gonna die, his abs, his pecs, his nipples-

He clears his throat. 

"U-uh, are you gonna stand the entire time?" He asks softly. "M-maybe it would be easier if you were...laying down."

Kirishima shivers. It's probably the cold air on his naked skin.

"Y-yeah, okay," he says just as quietly, easing back onto the bed. 

Bakugou swallows. 

Fuck.

"I-I should get closer right?" He asks, eyes locked on that smooth expanse of space between Kirishima's legs. " After all, I can't see anything from all the way over here."

Kirishima nods, nibbling his lip before he speaks.

"I was actually thinking...y-you could sit here. Between my legs."

Holy fucking shit, he's so hard. 

'Please don't look down.' He thinks as he shuffles forward.

He drops like a stone the minute he even thinks the moonlight will reveal his erection pushed up against his shorts, crawling the rest of the way forward until his directly in front of the other's still crossed legs. 

"O-okay...you good?"

Is Kirishima good?

Well his crush is sitting between his legs, and he's pretty sure they're about to have some form of sexual contact with one another. 

He's fucking ecstatic.

"Yeah, I'm okay. You?"

Bakugou's laugh is soft and pretty much completely hysterical.

"Yeah."

"Okay. Let's do this then..."

And...Bakugou knows what he asked for okay. 

He asked to see Kirishima's dicks. 

But it's one thing to ask for it, and another thing completely for it to actually happen. 

So when Kirishima spreads his legs for him? 

He nuts.

Just a little, in his boxers.

And sure, there's nothing there, but that's not the p-

Wait.

"What's that?" He asks, unconsciously reaching out to trace the thin scar traveling vertical down the redhead's pelvic area with two fingers. 

What he did not expect to happen was for the scar to split open.

Causing his fingers to sink slowly into some kind of wet, tightly sucking heat. 

Above him, Kirishima quickly clamped a hand over his mouth to stifle his shocked cry, his hips bucking forward, causing Bakugou's fingers to sink into the small further. 

"A-ah!"

The blond snatches his fingers back, trying to pretend both that Kirishima's whine of disappointment once he does doesn't go directly to his dick, and also to pretend that he doesn't immediately want to stick his now soaked fingers into his mouth and suck the juices off.

"Wh-! Wh-! Th-! What-!"

Kirishima is panting softly, his body having not been prepared for that sudden onslaught of pleasure. 

"Whoa, dude," he finally whispers.

Bakugou is still gaping like a fish, holding his hand like it'll fall off his body.

"What was that??"

Kirishima let's out a little giggle, leaning up on his elbows until he could look Bakugou in the face. 

"I forget the technical term for it? But I've always called it my slit. It's where I...store my dicks, I guess?"

"Your dicks are in that??"

"Yeah!"

"How??"

Kirishima shrugs. 

"I can't answer that. They're just...in there."

"Do they come out?"

"Of course! I have to pee and stuff, right?"

Bakugou swallows, glancing from his slit to his eyes and then back to his slit. 

"C-can I see?"

"Oh, uh, yeah, but uh..."

"But?"

"Well, I have to like...physically pull them out."

Bakugou's brain almost shuts down at the thought of Kirishima fingering his slit, coaxing his dicks out with slow, curling movements. 

"Fuck."

Kirishima blushes, scratching his cheek with a light laugh.

"Y-yeah, pretty gross huh?"

Gross?

GROSS??

Bakugou is literally going to have to burn these shorts because of how much precum he's leaking into them, and Kirishima thinks its GROSS?

He snaps his head up, glaring deeply into crimson eyes.

"It's not gross. It's you.  Nothing about you is gross, Kirishima."

He blushes hard, gaping at the blond in shock. 

"O-oh. Okay..."

Bakugou nods once, seemingly satisfied with the answer. 

"Now show me."

Oooh fuck, he's gonna die. 

But he's a man of his word.

He spreads his legs slowly, hesitantly. 

His slit is leaking fluids, causing a small wet spot on his sheets.

He's way too turned on. 

"Why is it wet?" Bakugou asks, his warm breath on Kirishima's skin making the redhead shiver. 

"Um...I guess it's like my version of precum?"

Bakugou hums softly, acting as if he doesn't want to absolutely slurp that liquid into his mouth.

But then he frowns. 

"Precum? Why? You didn't do anything to get turned on yet."

'Bold of you to assume just breathing your air doesn't turn me on.'

But Kirishima can't say that.

"U-uh well dude, you're pretty h o t," he replies instead with a strained laugh. 

Luckily he's looking anywhere but at Bakugou, because the blond is sure he just made the dumbest fucking face.

"Are you GAY?"

And now Kirishima is staring at him, surprised. 

"N-no?"

Bakugou deflates.

"I like to think of myself as an equal opportunity lover. But if you wanna slap a label on it, Mina says that's called being pansexual."

Holy FUCKING SHIT-

Bakugou almost fucking explodes.

"What?? I thought you were straight!!!"

"I said I would show you my dicks??? What about that would make you think I was straight???"

"But I've only seen you date girls!"

"I mean, yeah, but I've dated guys!"

Bakugou is frantically trying to kick start his brain cells into actually functioning.

"B-but-!"

Two hard knocks on the door shut them both up completely, both of their necks snapping to the source of the noise. 

"Oi! Quiet down in there!" Aizawa's voice says, muffled by the wood. "People are sleeping! Talk about Kirishima's dating life a little quieter!"

"Y-yes, sir!"

They wait until the teacher's footsteps disappear down the hall before facing each other again, both red faced.

But Bakugou is determined to continue this conversation, Aizawa and the other students be damned.

"S-so you like...boys, too?"

Kirishima's eyes lock on his.

The blond's eyes are fierce, focused on his with a laser like intensity, and shining with an emotion that Kirishima can now name. 

Hope.

Holy shit, could this be...?

He licks his dry lips, watching that red gaze flick down his mouth before snapping back to his.

"A-actually." He whispers, "there's only one boy that I like right now."

He sees the shutter come down over the blond's eyes, the way he leans away ever so slightly. 

"He's kinda tall, and blond with red eyes..."

Bakugou freezes.

Kirishima is feeling bold now. 

Now that he knows.

He spreads out leisurely on the bed, legs wide open as he gently traces over his slit. 

"He's so strong and manly," he whispers, watching Bakugou watching him, his eyes suddenly locked onto his hands.

"Just thinking about him gets me wet here," he says, moaning softly as he dips a finger inside of himself.

Bakugou twitches, ever so slightly. 

Kirishima whimpers, pushing in a second finger, gently stroking the underside of one of his dicks, causing his legs to quiver.

"He asked to see me tonight," Kirishima continues to whisper, moaning as his dicks get slicker, curling over his fingers. "Asked to see this. Wanted to know what was here, between my legs."

Bakugou swallows hard. 

"Do you wanna see, Bakugou...?"

"Please," he whispers.

Kirishima pushing just a little farther, hooking one of the twisting cocks onto his finger and pulling it out. 

Bakugou's breath leaves him in a punched out 'woosh'. 

"Holy shit."

It's...thick. God, it's so fucking thick.

Kirishima is hung.

Kirishima has two of these!!!

Bakugou lets out a shaky moan as he palms himself over his shorts, paying no mind to ungodly amount of stickiness now on his hand. 

"Oh, god. Oh, fuck. That's your dick."

Kirishima laughs, quiet and strained. 

"Yep. That's my dick, bro."

Bakugou can't stop staring.

It's big. 

Bigger than any dick, real or otherwise, he's ever seen in his life. 

But it's also completely different from any dick he's ever seen before. 

For one, it seemed...flat on one side.

"It's flat on one side."

Amazing observation, Brain.

Kirishima is still thrusting inside of himself, his hips gently rolling against his fingers in a way that makes Bakugou wanna swallow his dick. 

"T-that'll make sense in a second! I-if I can just-aha!"

It slides out with a slick sound.

Boom.

Two dicks.

Bakugou almost faints.

The second dick is just as big as the first, and Bakugou immediately sees what Kirishima means by he'll understand in a second, because the other dick has a flat side as well. If they were pushed together, they'd make one regular dick. 

A huge dick, but still.

"Holy shit..."

It's beautiful though.

They're beautiful. 

Shiny and red, with a pattern that almost looks like scales around the base of each.

"Birthmark," Kirishima says when he sees him looking. 

Bakugou almost doesn't hear him, too concentrated on reaching out to finally touch...

Kirishima's legs shake slightly when he makes contact, tracing his finger in a gentle circle around the head.

"Holy shit..."

"T-touch it more," Kirishima whispers, looking down at him with lust darkened eyes.

"I wanna do a lot more that touch," Bakugou replies gruffly.

Kirishima moans when Bakugou grips him a little more firmly, pressing both of his dicks together to stroke up and down. 

"Hhhhhholy motherfucking shit-" the redhead hisses, gripping his sheets tightly as pleasure rips through his body.

The blond moans softly, watching the other twist and thrust needily, hungrily taking in every movement he makes. 

"God you're hot," he whispers, feeling the dicks pulse in his hand. "And your dicks are hot, and I've been wanting to taste your precum all night, please say I can."

Kirishima's laugh is high and breathy. 

"Like I'm actually gonna say no to that, please suck my dicks, Bakugou, I'm literally begging you."

Well, if he's begging...

The first thing he does is tongue the slit where Kirishima's dicks are poking out, licking into the crevice.

Kirishima's hips jerk back in surprise, a gasp leaving his throat, but Bakugou just growls, wrapping his arms around the male's legs and yanking him back down, pushing deeper into the small space, licking at the wet walls as his dicks spill more of the clear fluid onto his face.

He moans, lo w a nd aroused, letting go of one of those thick legs so that he can finally free his own erection to the cool air of the room, immediately wrapping a hand around himself to give himself something to thrust into.

Kirishima's hips are shaking, his breath leaving him in soft pants as he tries to wrap his mind around the pleasure running through his veins. 

"B-bakug-AH!"

Oh fuck, oh fuck, one of his dicks is in Bakugou's mouth, holy SHIT-

He bites down on a pillow to muffle his wail.

Bakugou's trying his best to keep his eyes open, to watch the pleasure on that reddened face that he likes so much, but goddamn, the taste has them rolling back into his head. 

It's delicious. There's a hint of sweetness to it that makes his own dick throb.

Probably all those fruits and sweet shit he likes to eat. 

He eagerly slids the second dick into his mouth as well, pressing them together against the edges to form one single dick that he can take all the way into the back of his throat, swallowing firmly.

Kirishima's eyes pop open, staring at the wall in dazed shock. 

Bakugou's mouth is so hot, and the way he moves his tongue, fucking them in between the space his dicks press together is causing his toes to curl against the bed. 

"Ohhhhhh my fucking god-!"

Bakugou moans, the slick sounds of him rapidly fisting his own cock echoing through the room along with the loud sound of him swallowing and gagging on Kirishima's. 

The redhead can't stop himself from thrusting, his head falling back as he tries go shove himself deeper.

"How are you doing this, oh my god you lied, you said you were a virgin," he wheezes, his chest rising and falling quickly. 

He whimpers when the blond pulls away with a lewd slurp, his juices shining on swollen pink lips. 

Kirishima wants to kiss him so bad.

"I've never had much of a gag reflex," he says, voice rough. "Plus I've read some...stuff."

Even flushed and panting, Kirishima's grin causes his face to heat with embarrassment.

"Some stuff, huh?"

"I will leave."

"No, you won't~!"

Yeah. He won't.

"Fuck you."

"I was hoping that I could fuck you instead."

Bakugou's breath leaves in a woosh, his hole clenching in anticipation at the thought of those dicks inside of him. 

"Y-yeah, okay," he croaks out.

Kirishima's eyes widen in shock, but his pupils also dilate with lust.

And suddenly he's shooting upwards, scrambling to the night stand next to his bed and yanking it open to pull out a half full container of lube. 

Bakugou's hands are sweaty. 

Fuck. 

He's gonna get fucked.

He's as excited as he is nervous.

"C'mere," Kirishima says, motioning for the blond to come closer as he drops the lube on the bed and scoots back until his back is pressed against the wall.

He nods...and doesn't move. 

"Bakugou?"

"I think my legs are asleep..."

Kirishima bites back a snort.

"Why are you so cute? C'mere."

Bakugou is blushing heavily, but he still grips Kirishima's hand tightly when it's held out to him, grunting as he forces legs that feel like tv static to move.

Kirishima has a smile lingering at the edge of his lips when he pulls him into a kiss.

And sure, it's a little clumsy on Bakugou's part, but he makes up for it with eagerness, wrapping his arms around the other's neck as he moans softly into his mouth.

Kirishima let's out a groan of his own, his hands reaching down to gently wrap around a tiny waist.

And fuck, it's tiny. Like his fingertips are just barely brushing together tiny. 

"God, have you always been this small?"

"Shut the fuck up!"

But the blush on his cheeks answers that question for him. 

Kirishima is endeared.

And rock hard. So to speak.

He kisses the blond again, his hand flailing around the bed for a few seconds before he finally encounters the lube.

"Smooth moves," Bakugou chuckles into their kiss, his hands sliding against Kirishima's slightly sweaty back. 

"I'd like to see you do better."

"Mmmm..maybe another night."

Another night.

They were gonna do this again.

In his excitement, he pulls the male into another kiss, deeper this time, his tongue slipping in between slightly parted lips. 

Bakugou mewls, arching underneath him.

Kirishima moans, pushing his tongue deeper, tracing along the other's in a way that has him shivering violently, his dick twitching against his stomach. 

"Oh fuck," he whines when they finally break apart, his eyes bright and excited. 

Kirishima grins, smug.

"Pretty amazing, right?"

"Suck my ass."

His laugh is startled and a little louder than it probably should have been.

"What?!"

The blond is blushing, not looking in his direction. 

"Sorry. Denki kept showing me vines and tiktoks at lunch."

How the fuck could someone still be so cute after a statement like that?

And although he knows it wasn't really a request, he lifts the male's legs into the air anyways, grinning as he yelps in shock. 

"Kirishima, what the f-AH!"

He purrs, licking over the small hole lewdly.

"You said suck your ass," he says cheekily, pressing his tongue right up against the clenching hole before he can protest. 

Bakugou has to bite down on his fist to keep from yelling, his suddenly weak legs flailing in the air as pleasure consumes his senses.

The redhead is moaning softly, drooling and licking until the opening is loose and wet before shoving at least half of his tongue inside. 

Bakugou's legs are twitching and kicking, his head clouded with pleasure and what could possibly be brain damage.

"P-put my-ah! L-legs down! Headrush!"

He gasps in relief when Kirishima listens, gently dropping his legs back onto the bed.

"Sorry," he says sheepishly. "Got a little carried away."

"Don't be," the blond wheezed back, trying to make the room stop spinning. "Felt good."

"Gonna make it feel even better," Kirishima mumbles, suckling gently at a small, hard nipple as he flicks open the lube, pouring out enough to coat three of his fingers. 

"Knock knock," he coos, tapping his finger thrice against the wet hole before firmly pushing it inside.

Bakugou gasps, his hands clenching in the sheets. 

It doesn't hurt, not like they said it does in the fanfics (not that he reads those), but it's definitely uncomfortable having something up there. 

"Breathe, baby."

He exhales harshly, staring up at the ceiling.

"God, that feels so weird."

"Yup. Gonna feel weirder soon," Kirishima replies, dragging the sharp edge of his teeth across a nipple just to watch goosebumps break out across that pale flesh as he prods a second finger against the hole. 

"And then it's gonna feel really good."

Bakugou hisses when the second finger pushes in next to the first, trying not to tense up as a small amount of pain flares up against his backside. 

It hurt a little, but the fullness, the pressure...

His dick has never been so hard.

"F-fuck..."

Kirishima grins as he wraps a lube slicked hand around his dick, loving how he immediately deteriorates into bitten off curses and twitching. 

"Fu-AH! Wait! Wait! Don't!" The blond gasps, his body writhing against the black sheets as white hot pleasure zings up his spine.

He blindly reaches down, trying to shove the hand off and away as overwhelmed tears gather at the corners of his eyes.

"W-wait! Please! Please!"

Kirishima doesn't let go, but he does  stop, gripping his cock firmly and using only his thumb to circle the leaking head slowly.

Bakugou's chest is heaving, trying to blink the spots out of his vision as he slowly relaxes. 

"F-fuck..."

"If that's how you sound when I'm just jerking you off, Aizawa is gonna expel us tomorrow when I actually fuck you," Kirishima jokes. 

"Worth it..." He sighs back.

"Yeah, sure buddy. But just in case, how about we roll you over onto your belly?"

"Yeah, okay..."

Gentle hands grip his waist, shifting and nudging him until he's face down against the bed, his knees bend and legs spread in a way that makes Kirishima's dicks throb.

"Fuck."

He reaches down, gathering some of the wetness between his own legs instead of the lube that had been tossed to the floor by Bakugou's frantic movements earlier. 

"So pretty," he whispers as he coats the clenching hole with his own slick, some possessive roaring in his chest.

Bakugou moans when Kirishima pushes in the third finger, his hands digging into the pillow he's drooling on as his eyes roll back into his head. 

"Oh, f-fuck..."

"Soon," Kirishima grunts back, his fingers curling and twisting, pressing deeper. Searching for-

"FUCK!"

Found it.

"Oh my god, how did you find that so easily?" Bakugou gasps into the pillow. "I've been trying for months and I never have."

Kirishima's brain almost implodes at the thought of Bakugou fingering himself with only a thin wall between them. 

"I-it's just about the angle..."

"Well, that's definitely the right angle."

Kirishima laughs softly, watching the way Bakugou's hole clenches and flutters around his fingers with hunger. "Yeah...definitely is..."

He curls them again, pressing against the soft, spongy area and rubbing gently.

Bakugou's moan is still loud, but the pillow is a pretty good gag for the most part. 

Which is why Kirishima doesn't hesitate to get a little rougher, repeatedly assaulting that special button inside of him. 

"My dicks are gonna be the ones making you moan like that next."

He almost nuts from that idea alone, his mind filled with images of Kirishima inside of him, fucking him into the mattress until even the pillow can't muffle his screams of ecstasy.

"Please," he gasps. "Kirishima, please!"

"Fuck," the redhead hisses, yanking his fingers free.

The image of Bakugou face down and ass up with his hole wet, stretched and ready as he begs for Kirishima to fuck him will forever be seared into his mind.

"Please...!"

He grips one of the (completely soaked) dicks in his hand, gently pushing it against the small entrance.

"Fuck...gonna do this one at a time, okay baby?" He whispers, one large hand reaching down to tangle into soft blond hair. "Don't move."

Bakugou whimpers, nodding as much as he can. 

And then he's being split open, thick, pulsing heat pushing inside of him slowly.

Kirishima groan low in his throat as he pushes forward, the feeling of hot, wet, tight almost causing him to lose himself immediately inside of the other.

But he forces it back, focusing instead on breathing, however shaky it may be. 

"S-shit..."

Bakugou is no better. He's been moaning and shuddering since the tip first popped inside of him, stretching him father than he'd ever thought possible.

"Big!" He whimpered. 

"Fuck, baby, you already feel so good, and that's only one," Kirishima hisses, pushing deeper.

Bakugou has to physically bite the pillow he's holding to keep from yelling when Kirishima bottoms out inside of him, his other dick pressed hard and heavy between his plentiful asscheeks.

"Gooood job," Kirishima moans, rubbing a pale, round cheek before giving it a soft slap.

Bakugou is shocked when that small slap courses through his body like lightning, causing his cock to jerk violently. 

Kirishima notices, gasping when Bakugou clenches down on him tightly. 

"Oh? You liked that, baby?" He whispers into the small, flushed ear.

Bakugou swats a t him, burying his burning face into the sheets. 

"Shut the fuck up!"

The crack of Kirishima's palm connecting to his ass cheek is so loud he probably woke up not only the whole dorm, but the neighborhood, the entire Earth, and possibly the dead. 

"HAH!"

"Better watch your mouth," the redhead whispers, watching smugly as a perfect imprint of his hand blooms bright and red across his ass cheek. "Or I'll guarantee we get expelled."

Bakugou shudders, his mind fogged over, pain singing from his backside in an entirely different way.

But it's the kind of pain that makes his dick leak onto the sheets, his breathing shaky and aroused. 

"S-sorry..."

Kirishima hums in acknowledgment as he pulls his hips back, his eyes fluttering as a flush crawls up his face. 

"Oh God, Bakugou...s'good..."

The praise, the way he says his name, and the heavy press of his dick throbbing inside of him is causing Bakugou to descend into madness.

"Move!" He hisses. 

Kirishima obliges with a small groan, his hips pulling back slowly before shoving forward again.

He muffles a yelp into the soft fabric of Kirishima's pillow, mind going blank as the pointed head of his cock stabs as Bakugou's prostate, causing pleasure to unfurl hot and heady in his belly. 

"Ohhh my god," he whines as he pushes his hips back, chasing more of that feeling.

Kirishima is pretty much in the same boat, his teeth buried into his bottom lip as he starts to fuck the smaller male in slow, even strokes.

"Fuck, you feel perfect," he growls, moving his hand from the blond's hair to the back of his neck as his hips speed up.

He's focused not only on the heat wrapped around him, but also the way his other cock is fucking in between those plush cheeks with each rough thrust, fogging his mind with dual pleasurable sensations. 

"Fuuuuck," he groans, thrusting harder.

Bakugou mewls, looking over his shoulder with glazed red eyes as much as he can with Kirishima holding him down. 

"M-more...!"

"You want my other dick, baby boy?" He growls, shoving his hips forward a few more times just to hear him choke on his moans.

"Yes! Please," Bakugou gasps brokenly, his dick jumping in the air as his thoughts fill with the idea of being stretched around two thick dicks. "Fuck me!"

"God, for a virgin, you sure are a little slut," Kirishima says with a smirk, pulling out slowly.

Bakugou whines. 

Kirishima licks his lips hungrily, watching as both heads of his dicks rest lightly against the blond's fluttering hole, pressing in ever so gently. 

"You sure?" He asks one more time. 

Bakugou nods rapidly. 

"Please!"

It's...harder than one would think. 

Bakugou is still a little bit too tight, which he can tell from the way his hole immediately claps down once the heads pop inside. 

"Fuck," Kirishima swears breathlessly before gathering a large wad of spit in his mouth.

Bakugou gasps as the slightly cool sensation of spit lands squarely on his stretched hole as Kirishima lightly begins to fuck him again, spreading the wetness. 

"Fucking dirty," he whimpers, trying to ignore how much harder his dick was now because of it.

"Maybe just a little," the redhead agrees, pressing deeper. 

Bakugou's eyes pop open. 

Holy shit.

One was big, but two was...

"Fuck, fuck, wait, it's not gonna fit!" He gasps, reaching back to weakly push at Kirishima's thigh. 

"Of course, it will," he coos back.

He shoves his hips forward harshly at the same time he shoves Bakugou's face into the pillow, muffling his sudden scream.

"See? Perfect fit."

Bakugou is panting harshly, tears leaking from the corners of his eyes. 

"You fucking asshole..."

"I will be soon, don't worry."

It didn't hurt, at least not in the way you would usually think it would hearing that two dicks had suddenly been shoved into one hole. But it was definitely a stretch that he had to get used to. 

"J-just...don't move..."

Kirishima obliges, leaning down to kiss his back.

The feeling of soft lips eventually calms and untenses him, his breathing dropping back down to an almost stable level. 

"Don't move," he warns again, right before rolling his hips back. 

Kirishima hisses, his hands digging hard into small hips. 

"Bakugou, shit-!"

The blond ignores him, knowing that Kirishima is too much of a gentleman to move unless he has express permission.

He begins to rock his hips back and forth slowly, his eyes glazed over and mouth open to let out soft, needy noises of pleasure.

It eases the slight burn and causes his dick to twitch ever so often. 

"Feels good," he mewls. 

Kirishima is a goddamn mess. 

He can't even touch Bakugou anymore, one hardened hand digging into the headboard and the other into the wall as he fights not to thrust.

"B-bakugou," he wheezes, mouth dry and eyes following the slow, slick movements of that beautiful ass bouncing up and down on his dick. 

Bakugou hums, opening a hazy eye to peek over his shoulder. 

"Don' m've..."

Fuck. 

"Just a little bit, please," he begs desperately.

Bakugou's smirk is small and lopsided, but still 100% evil.

"Nah."

Kirishima swears, sweat sliding down his back. His dicks ache.

"Please, I'll do anything," he throws out, his brain clouded with the need to fuck. 

"Anything?"

"Anything!"

"Hmmm...m'kay. Just start s-AH!"

Kirishima rams his hips forward, a snarl on his lips as he sets a rough, brutal pace that has Bakugou's body and brain scrambling to catch up to the sudden onslaught of pleasure. 

"God, I can't believe you're letting me do this," he gasps.  "Wanted to fuck you for so long, wanted to see-"

Bakugou lets out a broken moan.

"-Thought you wouldn't want me, two dicks would be weird, but you did and you're here and fuck, you look so sexy on my dicks, babe."

"Please," he gasps, one hands reaching down.

Kirishima groans, his hips snapping faster, the impact of skin echoing through the room, as well as the sound of the headboard slamming against the wall.

In the back of his mind, a voice shouted at him, yelling that it was 1 a.m. and people were sleeping.

But how could he care about that little voice when his eyes were watching Bakugou fist his neglected cock so desperately that he was literally shaking from head to toe with the need to orgasm. 

"Fuck yes, that's it baby," he moans, fighting to keep his eyes open.  "Fist your dick and cum for me like a good boy."

Bakugou wails into the pillow as his orgasm rips through his body, hot, sticky strings of cum flying from his cock to soak the bed beneath his shaking legs.

Kirishima is still going, his breathing getting heavier and heavier.

"Please let me cum inside you," he whispers, his hips losing rhythm quickly as his orgasm began to build. "Thought about it so many times, wanna watch it leak out of you, wanna taste it-!"

"Please," Bakugou slurs, limbs heavy but body still shivering with orgasm aftershocks.

All he needed was permission. 

With a broken, shaky groan, he thrusts forward a few more times before stilling, a hot gush of cum shooting forward from both heads of his dicks to fill the blond. 

It was mind blowing, stars and colors bursting across his eyes.

It seemed to go on forever, his hips twitching lightly with each shot as he gasped for breath to fill his empty lungs. 

Bakugou shivered, moaning softly as the hot warmth filled him to capacity, until it was leaking out to drip down his now empty balls and shaking thighs.

Kirishima's strength immediately leaves him when he finishes with a soft moan or completion, sending them both crashing against the probably-ruined-forever bedding. 

"Holy fucking shit," he gasps to no one in particular. 

Bakugou hums in agreement.

It's quiet for so long that Kirishima is almost asleep when Bakugou finally speaks. 

"Kirishima?"

"Krmfh?"

"Remember earlier, when you said you would do anything if I let you move?"

Kirishima frowns with his eyes closed, wracking his brain for the memory.

"...Yeah? Why?"

"I know what I wanna ask."

"What's up?"

Bakugou isn't looking at him, his fingers tracing slowly around his nipple, and his voice is shaky when he speaks. 

"I-I wanna be your boyfriend..."

Kirishima almost explodes, his brain screeching to a halt before starting again all at once.

His face breaks out into the brightest, happiest grin Bakugou has ever seen, eyes practically sparkling with excitement.

"Yes! I would love to be your boyfriend!"

Bakugou visibly sags with relief, his breath leaving him in an exhausted woosh.

"Oh, thank god..."

Kirishima is still smiling when they cuddle up, Bakugou as the little spoon with Kirishima's (now soft) dicks still inside of him.

"Goodnight boyfriend," he whispers cutely, planting a smacking kiss on the blond's cheek that has him frowning to hide a smile.

"Ugh. I regret this already."

"No, you don't," Kirishima replies in a singsong voice. 

"Hmph."

They settle pretty quickly, breathing evening and limbs relaxing. 

It's quiet for so long that Kirishima is almost asleep when Bakugou speaks again.

"Next time, I wanna fuck your slit."

His eyes pop open.
