When Kirishima and Bakugou walk into class B's dorm, Tetsutetsu is sitting in
the living room as promised, Monoma next to him on the couch, both of them with
their backs to the entryway.
Kirishima brings a finger to his lips and gestures wildly at the rest of the
class. He puts his hands over Tetsutetsu's eyes.
"Guess who?" Kendou says, half amused, half apathetic.
Tetsutetsu brings his hands up, paws at Kirishima's. "Fuck, don't I get a
hint?"
Kirishima tilts Tetsutetsu's head back and kisses him upside-down.
Monoma retches.
"Hey, Kiri!" Tetsutetsu laughs, smacking Monoma up the head without turning to
look. "Bro, there you are! Again, sorry for the delay, I really did my best."
Kirishima takes his eyes off Tetsutetsu to make eye contact with Shiozaki. She
flushes and looks away.
"C'mon, don't be a dick", Tetsutetsu says, pulling on Kirishima's hand to get
his attention. "I thought that was his job."
Bakugou snarls. "And here I thought it was your job."
Tetsutetsu slaps a hand on Monoma's mouth before Monoma can respond.
"Okay, let's all stop being dicks", Kirishima says. "If we're a bother, Tetsu,
we can leave."
"Okay I know what you're doing and joke's on you cause I don't actually mind
admitting that I want you here in front of people, unlike some who shall not be
named."
Bakugou's eyebrows rise. "Really now?"
Kirishima puts his hands up. "No Katsuki that wasn't a challenge--"
Bakugou rudely interrupts by shoving his tongue down Kirishima's throat.
Tsunotori and Shishida go wild. Pretty much everyone else enters a fight-or-
flight state.
"Okay that's enough we get your point", Tetsutetsu rushes to say, standing up,
apparently in with the fight-or-flight lot. "Yes you guys are totally fine with
PDA we understand-- oh holy shit okay this is borderline exhibitionism at this
point." He grabs Kirishima who's holding onto Bakugou and drags them both to
the elevators. He slams the button. "Alright I've fucking been in your class'
dorm, I know you shits don't give a flying fuck about this kinda stuff but
you're seriously melting brains right now, oh my fuck, stop that."
The elevator doors blessedly open and he ducks all three of them out of sight
from the rest of the class. Through the door he can still hear Tsunotori and
Shishida howling.
Bakugou unsticks his face from Kirishima's. "What's the matter, hellfuck? You
look a little winded."
"Pardon my fucking ass for getting stressed over having to save my whole class
from sexual assault", Tetsutetsu snaps back. "This shit does not happen in this
class - I don't care what you have going on with your own class, but that shit
was uncalled for."
Kirishima tilts his head. "We wouldn't have gone that far, Tetsu - we were just
making out."
"Just making out? Kiri I'm serious that was actuallyborderline exhibitionism!
You can't do that shit without consent and I sure as hell don't recall either
of you asking my entire goddamn class about this!"
Kirishima drops his hands from Bakugou, suddenly unnerved at the notion. "We
didn't mean-- I'm sorry, you're right. We're sorry."
"I'm fucking not", Bakugou huffs. "That was literally just making out. None of
that could qualify for assault."
Tetsutetsu steps out of the elevator and down the hall. "Are you seriously
playing a technicality right now? Shit kinda heroyou're gonna make! If any of
them had given me half a reason to think they felt bad, I would skin you alive
right now."
Bakugou barely waits for Tetsutetsu to open his door. "Just you fucking try it,
bitch."
Kirishima rolls his eyes and pulls Bakugou in Tetsutetsu's room.
Bakugou insists, doesn't even give Tetsutetsu enough time to lock the door
before he slams a crackling hand on the doorframe. "Don't you fucking dare
accuse me of this shit ever again."
Tetsutetsu bites Bakugou's face.
Kirishima panics and reaches around Bakugou to push Tetsutetsu back against his
own door by the neck.
"I'm fine", Bakugou growls. "I'm not gonna fucking break, Ei."
"Babe excuse me but only one of us has flat teeth and yielding flesh."
"Yeah well that one happens to also be the one who likes getting bled the most
so shut the fuck up, babe."
Tetsutetsu laughs. "Is that why you're here? Got two shark mouths to mark you
up?"
Bakugou growls. "Fucking try me, bitch."
Tetsutetsu grins.
"Oh shit", Kirishima goes.
Bakugou shoves his arm across Tetsutetsu's chest and pushes him back against
the door. Tetsutetsu makes a noise of delight that could easily be mistaken for
a grunt at having his back slammed against wood. His hands grab at Bakugou's
hips, pull at his shirt.
Bakugou pins Tetsutetsu's wrists to the door.
Kirishima drapes himself across Bakugou's back and grabs hold of Bakugou's
hands on Tetsutetsu's wrists, and the explosions stop firing against the metal
there while they make out. Kirishima occupies himself with Bakugou's neck,
leaving wet kisses, soft bruises, light bitemarks.
Tetsutetsu, on the other hand, might as well be cutting Bakugou's lip off. He
bites hard and vicious and when he leaves Bakugou's mouth (to attack his neck)
it's bleeding and bruised badly.
Tetsutetsu bites at Bakugou's collarbone, and Bakugou groans and slouches to
get back at eye level with Tetsutetsu.
"No you don't", Kirishima says. He wraps an arm around Bakugou's chest, holds
him up.
Tetsutetsu grins. He wiggles his hands out from under Bakugou's and kneels.
"I am not trusting those teeth anywhere near my junk", Bakugou says, struggling
against Kirishima. "Ei I will kill you, let me down."
"Nu-uh", Kirishima hums into the nape of Bakugou's neck. "If you can trust my
teeth then you can trust Tetsu's."
Tetsutetsu, ever the asshole, shoves Bakugou's shirt up against Kirishima's arm
and bites the highest spot of skin exposed - Bakugou's pec. "Can he really?"
Kirishima grabs Tetsutetsu by the hair and slams his head back against the
door. "Yes, he can. Right, Tetsu?"
Tetsutetsu glares, but Bakugou is taller than Kirishima so he's the receiver of
the glare.
Kirishima tugs. "Right, Tetsu?"
"Fuck, fine", Tetsutetsu growls.
Kirishima goes back to holding Bakugou's wrists pinned to the door and making
out with his neck. Maybe occasionally rolling his hips into Bakugou's.
Bakugou arches his back, leans his head to the side. Stares down Tetsutetsu.
Tetsutetsu continues biting what he can reach of Bakugou. His mouth is smeared
with blood. He tugs down Bakugou's pants, baggy as they are, and leaves a messy
kiss into his hip as a no-bite promise before he gives Bakugou an experimental
lick.
Bakugou hisses. "I'll seriously murder you if you bite."
Tetsutetsu hums, continues.
Kirishima, as previously mentioned, is shorter than Bakugou, and therefore
despite his best efforts, he can't hook his chin on Bakugou's shoulder and
watch the show. Well, he can, if he tip toes, but he'd get tired that way. He
bites Bakugou's shoulder blade and goes up to the balls of his feet, hardens
them to lock the joints in place.
Tetsutetsu sees Kirishima peeking up from over Bakugou's shoulder and grins as
best as he can with his mouth full.
"Oh, damn", Kirishima says. "Shit, Tetsu, you're looking great."
Bakugou grumbles, jerks his head to the side to bury his mouth on his own
bicep.
Kirishima rolls his hips. "Doesn't he look great, Katsuki?"
Tetsutetsu gives Kirishima a cat blink, thrilled.
Kirishima grins in return. He bites Bakugou's ear. "Doesn't he, Katsuki?"
"Stop being a manipulative bitch", Bakugou growls into his own arm.
"I'll stop being a manipulating bitch when the two of you stop being dishonest
little whiny shits."
Bakugou snarls. "He looks great."
"You're telling me? Tell him."
Bakugou knocks his head back into Kirishima's face. He glares down at
Tetsutetsu. "You look fucking great, if I could paint sin and pin it up it
would look like you right now."
Tetsutetsu pulls off Bakugou and covers his face. "Holy fuck."
Bakugou sees an opening, slams his elbows up into Kirishima's arms and finally
frees his hands. He drops down.
Kirishima crouches behind him. He pulls at Tetsutetsu's hands, kisses him over
Bakugou's head.
Tetsutetsu remains flustered beyond coherence.
"You broke him", Kirishima says.
"You broke me, babe", Bakugou says, leaning back into Kirishima's chest. "Don't
fucking make me say sappy shit."
Kirishima pauses. "Really?"
"Yeah. Please."
"Okay. I'm sorry, love."
Bakugou twists around to kiss Kirishima. "Just don't fucking do it again." He
turns back around, finds Tetsutetsu staring. "What."
"Love?"
"Yes fuckass, because I'm actually dating him, eat shit."
Tetsutetsu snorts. "That your attempt to make me jealous?"
Bakugou rolls his eyes. "Please, like you have any right to be jealous."
"I'm getting kinda jealous", Kirishima says, chin planted firmly on Bakugou's
shoulder. "That Katsuki got that glorious blowjob."
"Aw, honey", Tetsutetsu laughs. "I can get you a blowjob."
"Hmm, no. Not now, at least. Maybe some other time."
"Whenever you want", Tetsutetsu purrs, and dives into the crook of Bakugou's
neck.
Kirishima giggles and takes to Bakugou's other side.
Bakugou curses.
Kirishima traces a bite mark with his tongue. "Babe can we get naked already?
This is tiring."
Tetsutetsu has the audacity to snort with his fangs still sunk in Bakugou's
flesh.
"I'll fucking blow your clothes off if you complain again", Bakugou growls,
pulling at Tetsutetsu's shirt. "You're not the one getting teased from both
sides here."
"Now that's an interesting way to phrase things", Kirishima says, doing his
part in the mass effort to remove all articles of clothing between them.
"Though that might actually kill you."
"Will not."
"You're getting pale, love."
Bakugou holds a hand up, palm down, watches it tremor. "I'm fine."
"Dude you're bleeding so much I'm worried it'll seep into the floor",
Tetsutetsu says. "Oh, Kiri, there's stuff behind you in the--"
"I know, I got it."
"I'm fine, fucking go for it", Bakugou says.
Tetsutetsu finishes stripping both of them. "Are you, though?"
"Don't fucking flatter yourself", Bakugou growls, tossing his pants to the
side. "Your bite isn't that tough, fucker."
Tetsutetsu takes it as a challenge, bites hard and vicious into Bakugou's
deltoid. Bakugou curses, responds with a sharp hair yank.
Kirishima takes it in, from where he stands.
Then he promptly takes his shirt off and fits back in his spot behind Bakugou.
He catches Tetsutetsu's mouth over Bakugou's shoulder.
Bakugou turns to look.
Kirishima and Tetsutetsu both harden at the same time, and the noises of their
makeout go from wet to clanging.
Kirishima pushes up against Bakugou's back, nudging him onto Tetsutetsu's lap.
He pulls back to breathe and also take stock of what he's brought over.
"Okay, catch", he says, throws two condoms over Bakugou's shoulder. He then
takes a moment to admire the two boys rushing to put them on. Kirishima rolls
on the third one himself.
"I am not fucking doubling this shit", Bakugou says.
"No yeah I know, you'd die", Kirishima says, slathering lube on his hand.
"Fuck you."
"Not me, love." Kirishima plants a kiss on Bakugou's hair and moves to finger
him.
Bakugou slams his head into the crook of Tetsutetsu's shoulder.
"Aw, no fair", Tetsutetsu says.
"Yeah he makes some pretty glorious faces", Kirishima agrees. "But let him. You
think I can finger you both at the same time?"
Tetsutetsu laughs. "Won't hurt to try!"
Kirishima tries. Tetsutetsu is suddenly glad that Bakugou's hiding in his
shoulder.
Kirishima grins. "You look good, Tetsu. You both look good, actually, but
you're at least showing me your face."
"You've seen my face", Bakugou whimpers.
"You good, love?"
Bakugou takes a deep breath and turns just enough to look at Kirishima. "I'm
good."
"I'm gonna get Tetsu in you, okay?"
"Sure."
"Tetsu?"
Tetsutetsu grins. "Are you gonna get in me though?"
"Yeah I'd hope so."
"Then deal."
Kirishima giggles into Bakugou's spine as he lines Tetsutetsu up.
Tetsutetsu thrusts up. Bakugou bites.
"Aha", Bakugou says. He drives his thumb into the bitemark he just made on
Tetsutetsu's throat. "Now you're the one bleeding, though guy."
Tetsutetsu covers his skin in steel - stopping his bleeding - and runs his hand
up Bakugou's side - along his wounds. He holds his bloodsoaked palm up for
Bakugou to see. "Care to repeat that?"
Kirishima pinches the inside of Tetsutetsu's thigh. "Careful with your quirk,
dude."
Tetsutetsu laughs. His skin grows soft. "Sorry, come on."
Kirishima rolls his eyes, but still gives him a kiss before slipping into him.
Tetsutetsu bites his own lip. "Move, Kiri, please."
He does. Tetsutetsu tries to match the rhythm, fails miserably. Bakugou clicks
his tongue and takes it upon himself to ride Tetsutetsu in Kirishima's pace,
feeling the chest on his back grind up against him every time Kirishima moves.
It's a lot. The most Tetsutetsu can do is bite at Bakugou, but even that's
become weak with overwhelm. And thank fuck for that, because Bakugou's head is
starting to spin with blood loss.
Actually no, it's spinning for more reasons than that, it turns out, because
it's only a quick while before Bakugou finishes with a quiet moan. He slips
Tetsutetsu out and leans back against Kirishima, more than glad to close his
eyes and go dizzy with blood loss and afterglow and Kirishima's increased vigor
in getting Tetsutetsu off, hearing heavy breaths in his ear.
He blacks out.
Bakugou opens his eyes again when something stings him in the throat.
"Shit!" he yells, shooting upright (when did he lie down) and pushing
Kirishima's hands away. "Fuck, that hurts!"
"It's gotta", Kirishima says, and pats gauge over a wound again. "I'm not
letting you walk out of here without disinfecting these first."
Bakugou grumbles, doesn't react to the burn now that he expects it. "Did I pass
out?"
"You were talking", Tetsutetsu says, from his bathroom. He's left the door open
and he's leaning over the sink to take care of his own bleeding bite mark. "You
weren't very coherent though."
"What did I say?"
"You thought it was incredibly interesting that, while I was the one who was
all but biting chunks of your flesh off, my quirk makes me smooth, and Kiri's
makes him sharp when he's gentle with his teeth", Tetsutetsu says. He tapes
gauge on his neck. "It was pretty funny."
"You didn't phrase it like that, exactly", Kirishima says. He moves on to the
other side of Bakugou's throat. "But yeah, that's the gist of it."
Bakugou clicks his tongue. "That's dumb as shit."
"It's an interesting observation", Kirishima says, cleaning out the wounds on
Bakugou's chest. Then his sides. Then the single one on his hip.
Tetsutetsu comes back in his room. "You need help with that?"
"You touch my bleeding flesh, I'll cut your motherfucking head off", Bakugou
snarls.
"Katsuki."
"No, it's fine", Tetsutetsu says, putting his hands up. "He does have a point."
Kirishima stands. "Love, can you stand up?"
"Of course I can, fuck you", Bakugou says, but still leans heavy on Kirishima
to get up on his wobbling feet.
"Maybe blood loss and tough fuck wasn't the best combination", Kirishima says.
"I'm fine."
"Sure, babe."
"I'm fine!" Bakugou attempts to stand on his own, grabs back onto Kirishima.
"Fuck. When did you get me in pants?"
"When you were muttering about my sharp edges."
Tetsutetsu picks up Bakugou's shirt and wrestles it on him. "There you go, now
we're all set."
Bakugou looks, and yeah, they're all indeed dressed. Tetsutetsu's wearing a
different shirt than before, though. Did Bakugou bleed on the previous one? He
looks to the floor in front of the door and finds no blood there, either.
They've cleaned up already. They're really all set.
"We should get you back to our dorm", Kirishima says, settling Bakugou's weight
against his side. "Get you to lie down, maybe I can steal some juice from
Iida."
Bakugou just nods.
"I'll walk you out", Tetsutetsu says. "If you see Monoma get his shit grin on,
you know the one, just run for it, I'll distract him."
"Tetsu, bro, I wouldn't leave you behind! That's not manly at all!"
"I'll live", Tetsutetsu laughs, going down the hall. "Forget about me, just
save yourselves. I can tackle Noma, but I can't promise anything with Tori and
Shishi down there, though. Especially if they find Kama to team up with. Then
you should really run."
"I have no idea who any of those are", Bakugou grits out.
"Noma is Monoma", Tetsutetsu says, frowning in confusion. "The, the Copy guy?
From the cavalry battle? Don't you remember him?"
"The other ones."
"Tori is Tsunotori Pony, her quirk is, uh, Pony. Shishida's Beast. Kamakiri is
the praying mantis one, his quirk is Sharp Blade."
Bakugou snorts. "Animals, huh?"
Kirishima laughs, too. "Don't be like that, Katsuki."
"Nah, he has a point", Tetsutetsu says. He calls for the elevator. "I don't
know if it's their quirks that make them like that, but yeah, they get pretty
wild."
"That's fucking funny", Bakugou says. "The animal quirks in our class are very
fucking dignified."
Kirishima walks them both into the elevator, looks to the ceiling in thought.
"Huh."
"What, seriously?" Tetsutetsu laughs. "I mean I was expecting that from the
bird, and I can kinda see froggy all polite, but the Tail guy?"
"I'm pretty sure he isn't part animal. His tail kinda looks like a human's
tail, you know?" Kirishima resettles his hand on Bakugou's waist. "But yeah, he
teases, sure, but I think he's embarrassed he's gonna get teased back. He's
pretty new to the whole sex thing."
The elevator doors open, and as promised, Tetsutetsu dives for Monoma, giving
Kirishima and Bakugou the chance to escape. Kamakiri's nowhere to be found, but
Tsunotori and Shishida go hog fucking wild.
Tetsutetsu yells for Shiozaki, and she makes a vine wall to seperate the lounge
area from the exit. Kuroiro manages to slip past it, but doesn't have any time
to be a little shit before he's enveloped in vines and forcibly dragged back.
Kirishima and Bakugou escape, laughing loud and stumbling as they struggle to
walk with their weights shared.
