Summary
     bnha kink meme fill for the prompt "Kirishima, Bakugou & Deku stay
     out late one night sparring and end up getting a little too amped up,
     which leads into locker room/shower sex. Extra points if they're
     rough about it."
Notes
     inspired by this amazing artwork that can be found here
It had been a good gym session, Midoriya thinks, as he scrubs the sweat and
grime off of him in the communal showers. Though he isn't progressing with One
For All as quickly as he'd like, he's still getting stronger every day, and
that's what matters. These things take time and patience, and he'll have to
work twice as hard as anyone else, but he'll get there. Unlike Kacchan,
Midoriya wasn't graced from birth with a flashy, strong quirk; he wasn't lucky
enough to have his entire childhood to build his strength and learn to control
it.
He hears whispers behind him.
Speaking of Kacchan...
Midoriya glances over his shoulder and catches Kirishima's eye. Surely he's
just being paranoid, but he can't help but feel like he's being talked about.
Kirishima and Kacchan are in the line of showers opposite him, in stalls side-
by-side. They had been in the gym the same time he had been, sparring together
in a training room and then wrapping it up with some weight-lifting. Right
after Midoriya left for the showers, they came in as well, and ever since then
the hairs on the back of his neck have been standing on end, his senses telling
him he's being watched.
When Kirishima notices him looking, he turns back around as if nothing happened
and continues to wash himself, his voice low and muted under the shower spray.
Midoriya's eyes travel down, sweeping over the curve of his well-toned ass
before he whips his head back around to face the tile wall.
“Deku's watching you, that fucking pervert.” Kacchan's voice carries louder
than it had the rest of their conversation, and Midoriya's face burns. He's
been caught.
He wants to explain himself to Kirishima. He really respects him and considers
him a friend, and it would be no good if Kirishima started to get the wrong
idea about him – but at the same time, Kacchan would likely confront him, and
Midoriya seems to always clam up around him, his tongue either not working or
working too well, words spilling out against his will.
So he decides the best course of action is to stay silent and pretend he didn't
hear.
Of course, it's not that simple.
 
He runs his towel through his curly locks, trying to dry it as well as he can
before getting dressed. He has nothing but a short towel wrapped around his
waist, but the steam from the showers makes the locker room plenty warm.
Kirishima and Kacchan come walking in then, and Midoriya blushes again. He can
feel their eyes on him, and he nibbles his bottom lip, worried they'll say
something to him that'll start one of his embarrassing rambles. His
relationship with Kacchan is beyond salvageable – he's accepted that, though
reluctantly. But his friendship with Kirishima is just beginning and holds a
lot of promise; he doesn't want Kacchan to drive a wedge between them over some
misplaced jealousy.
“Hey, Midoriya,” Kirishima says, jolting Midoriya from his thoughts. His
shoulders bunch and he whirls around to see Kirishima's brilliant smile. “We
need you to settle a bet for us,” He continues, jerking a thumb at Kacchan
who's sneering at him. Midoriya wills himself not to look down, where his
childhood friend has absolutely nothing on. “Bakugou thinks you were checking
me out in the showers, but I think he's wrong. You'll back me up, right?”
It's said with innocence. Kirishima's expression holds no ill-intent, as open
and honest as always, his sharp teeth glinting under the harsh florescent
lights. But Kacchan has his mouth twisted to the side in an angry pout – which
is, admittedly, not out of the ordinary for him, but still unnerving. Something
feels off about this, though Midoriya can't place why.
“W-well, what are the terms of the bet?” He asks, and swallows around a lump in
his throat. He doesn't know why he asked that, he should have just answered
straight away and left the locker room before he could do any more damage with
this stupid mouth of his, but at the same time he's too curious. Why would they
bet on that sort of thing, and why would Kacchan of all people want to know?
Kacchan's sneer morphs into a grin, and the curiosity Midoriya felt is replaced
by a simmering dread. He definitely should have just denied it, why does he
always always lose his head around him?
Panicking, Midoriya looks to Kirishima for guidance, hoping to see some
semblance of sympathy in his friend's eyes. But Kirishima's friendly smile now
seems less so. Now it looks like a hungry predator's, and Midoriya has to bite
back a squeak at the sight.
“The terms of the bet,” Kirishima answers at length, glancing at his partner,
“were that if I'm right, Bakugou's gotta take it up the ass for a week-”
Midoriya has blushed so hard he feels faint.
“-but if he's right, then you could, maybe, do whatever you want to me? While
he watches?” Kirishima's blushing too, the tops of his cheeks and tips of his
ears dusted in pink. He shuffles on his feet nervously, and Midoriya watches a
water drips from his hair, painting glistening trails down his sculpted chest.
His eyes snap up to meet the redhead's, and he knows he's been caught again
with the way his smile widens.
Midoriya's eyes flicker between the two, his brain wracking for a logical, sane
reasoning behind this scene. Kirishima and Kacchan were suspected of being more
than friends, and now he has confirmation of it, unless perhaps this would be
the first time for them too, but no that doesn't seem likely, there was a
familiarity with the way Kirishima talked about sex with Kacchan, as if they've
done it before and are comfortable with it. But why would Kacchan want to
watch, what does he gain from that? And how does Kirishima know he's attracted
to him, has he been that obvious with it? Yeah he's got a really nice body and
a cool, useful quirk, but does he really want to engage in a sexual
relationship with -
“Holy shit, Deku,” Kacchan snaps, stomping forward. It's then Midoriya realizes
he'd been muttering all that out loud, and when Kacchan grabs his arm he yelps,
mortified. Kirishima's laughing. He's dragged over by Kacchan to stand in front
of the redhead. “Kiss him,” He commands.
Kirishima waves his hands in front of him placating. “Whoa whoa whoa, Bakugou
man you can't force him.” He looks at Midoriya, a gentle smile playing on his
lips. “So, what do you say? Did Bakugou win the bet? Or am I totally off base
in thinking you want me as much as I want you?”
Midoriya's head spins, his heart races. He does want Kirishima, who wouldn't,
he thinks? But he feels Kacchan's presence behind him, like a black hole
threatening to decimate him into nothingness. He doesn't know if it's safe to
answer truthfully.
But Kirishima wouldn't let Kacchan hurt him, he knows that. He doesn't know if
he can trust Kacchan, but, he knows he can trust Kirishima.
Midoriya nods. “Yeah.”
“Yeah what?” Kacchan says, shaking his arm for emphasis.
“Y-yeah, yes. I want you, Kirishima.”
His grin stretches until all his sharp teeth are showing. “Awesome!”
And all at once the mood shifts. Midoriya's hyper aware of Kacchan's hand on
his arm, the coarse pad of his thumb rubbing along the scar there. He sees,
almost as if in slow-motion, Kirishima reach forward and run the tips of his
fingers down Midoriya's chest, his skin pebbling in the wake of his touch. The
tilt of Kirishima's head as he watches, pulling his bottom lip between his
teeth, his eyes lidded and his blush growing deeper, redder.
Kacchan lets go of his arm, moving to sit on the bench nearby. Midoriya watches
him and tries to hide the slight disappointment he feels at his absence.
Kacchan was never a part of the deal.
Even if, deep down, he has always...
His jaw is being held, turned until he meets Kirishima's eyes. They sparkle
with mirth, and Midoriya knows he can read his mind. The redhead leans forward
and presses his lips to his.
Midoriya's never been kissed before. He's practiced before, though, when he was
younger: with his hand, with a pillow, against a mirror. Unsurprisingly, none
of it prepared him for the real thing.
Kirishima's lips are warm and lightly chapped. They move across his with all
the gentleness of a lover, skimming against the surface without going any
deeper, giving Midoriya the chance to grow accustomed to the new sensation. He
feels Kirishima's arms cup his face, stroking his jawline and cheeks, his
fingers cool against his searing skin.
Midoriya's hard already, much to his dismay. He can feel Kacchan's eyes on him,
boring holes in him, and he's sorely tempted to pull away and run out of the
locker room, run back to his dorm and hide himself away forever. But
Kirishima's hands on him ground him, and when his tongue slips between his lips
Midoriya welcomes it. He opens and feels the smooth wet muscle stroke into him,
licking and swirling and pressing, and soon Midoriya's pressing back, mimicking
Kirishima's movements, grasping at the hard muscle of his biceps. He's almost
forgotten Kacchan's watching until he speaks.
“This is taking too fucking long.” He growls, and the pair break apart from
their kiss to look at him. Kacchan's got his cock in his hand, pumping it in a
lazy rhythm, eyes flat and bored. It's only at half-mast, and Midoriya stares
openly. He's never seen it like this before, never felt he had permission to
get a good look until now.
“What is it, Deku?” He mocks, and wags his cock at him.
Kirishima's voice is disapproving. “Don't rush him, it's his first time.”
“He's already hard! Just fuck him.”
“Dude, we don't know if that's what he wants!” Kirishima says, then halting,
looks at Midoriya. “Is that what you want?”
Midoriya swallows. Is that what he wants? He doesn't know. Kissing Kirishima
was pretty nice, but he's never had sex before. It's not that he's unwilling,
it's that he's scared. He'd be nervous enough if it was just Kirishima – but
Kacchan is here too, watching and touching himself to the show they're putting
on, and it's all a bit much.
But, he doesn't want it to stop.
“Y-yes,” He stammers when he can find his voice again. He feels warmth in his
chest at Kirishima's pleased expression, and something tugs forcefully in his
stomach when he sees Kacchan stand, a feral grin stretching his mouth.
“Let's fucking move this along, then,” Kacchan says, voice low, and he comes
around to stand behind him, hands grabbing his hips tightly. “Spread your legs,
Deku.”
He complies. Fingers dip in his ass cheeks, spreading them apart. He gasps.
Kirishima pulls away to go to his locker, rummaging in it for a second before
returning with a bottle, holding it up triumphantly. “I came prepared!”
He passes the bottle of lube around to Kacchan. Midoriya hears the top pop, but
Kirishima's grabbing his face and kissing him again, rougher this time, tongue
diving in immediately to resume the pace they reached before. So when the
fingers that were kneading his ass reappear against his hole, slippery and
cool, his mouth is too occupied to protest.
Not that he would have. Oh, not at all – the first press of a slickened finger
is pleasant and familiar; Midoriya's a virgin, but he's played with his own ass
before, so this is nothing new to him. But where his own finger is ordinary and
known, Kacchan's finger is thicker and longer, foreign and rough in its
movements. He wiggles it in to the knuckle in one go, and Midoriya can hear him
chuckle darkly in his ear.
“You ate that right up, Deku... you finger fuck yourself thinking about
Kirishima?”
Midoriya burns with shame. He's still kissing Kirishima, but the kiss has grown
sloppy and wet, saliva smearing their cheeks and lips. Kirishima's hands roam,
pull the towel off of Midoriya's hips and expose him.
“Or do you think about me?” He finishes. Midoriya can't see him, but he can
picture the taunting smile he's wearing perfectly in his mind, and his cock
twitches in want.
“Both! Both of you!” He gasps when Kirishima lets up on him. Now Kirishima
laughs, the tenor high and breathy. He sounds just as gone as Midoriya.
“You want us both, baby?” He purrs, leaning in to nip at the tender skin in the
crook of his neck. Midoriya arches his back and crooks his neck, asking without
words for more. His back touches Kacchan's chest, he feels his breath ghosting
over his ear, and all the doubts he was having before disappear.
This will be a night he remembers forever.
Kacchan adds a second finger without warning, and Midoriya sucks in a breath,
pushing past the initial discomfort. The fit is a little tighter, but he
quickly adapts to it, relaxing his muscles around the intrusion and letting his
head fall back to rest on Kacchan's shoulder. Teeth sink into Midoriya's
shoulder and through a wince he sees Kacchan smiling around the skin in his
mouth, his eyes sharp and focused on Midoriya. The gaze is not like the normal
one of disgust and derision, but the opposite. It suddenly occurs to Midoriya
that he's sandwiched between two ravenous animals, and he's the feast.
This thought should scare him, but it doesn't. Instead he moans at the tongue
lapping at the bite mark, he starts to shift back onto the fingers inside him,
fucking and stretching him out, he revels in Kirishima's worshiping hands still
exploring his skin, tweaking his nipples.
A third finger is added then, and this time it's not as easy going in. Kacchan
has to force it in, scissoring his fingers to make the room and squeezing
Midoriya's arm with his free hand, reminding him in his own way to breath and
relax. The hand leaves him and he hears the bottle of lube open again, feels
the cool liquid splash down his ass crack, drenching him. Kacchan works the
lube in with his fingers, twisting and thrusting hard, rocking Midoriya forward
to lean against Kirishima.
“Is he ready yet?” Kirishima asks over his shoulder, talking to Kacchan. Then
softer, in his ear, “Are you ready for me, Midoriya?”
He's not sure he can speak, so he nods, the smooth skin of Kirishima's chest
brushing against his forehead.
The fingers withdraw suddenly and he whimpers, but before he can figure out
what's happening he's being spun around. He's facing Kacchan, now, and his
nerves return in full force. His legs tremble under his piercing stare. He
still can't believe that Kacchan would want to do this with him, that he is
doing this with him.
Kirishima grabs his wrist and tugs him back to where he's moved to sit on the
bench in front of the lockers, towel still wrapped around his hips. His cock
peeks out from under the towel, pink and leaking. Kirishima pushes the towel up
and takes Midoriya by the waist, guiding him back to straddle his legs. It's
awkward at first, but after some maneuvering and lifting, Kirishima's able to
get Midoriya's back flush against his chest, his hands in the bend of his
knees, and hold him up.
Kacchan leans over in front of him and grabs Kirishima's dick. He lines him up,
and Kirishima begins to lower Midoriya.
Kirishima's cock is thicker than the fingers combined, and Midoriya doesn't
even try to hold back the moan that's ripped from his chest. His voice is loud
and keening as Kirishima slowly pushes him down, his slickened hole sucking him
in after a moment with minimal resistance.
Before he can get his bearings, Kacchan is standing before him, fisting his
dick and glowering down at him.
“Make yourself useful for once, Deku.” He says around a smirk, and he gives his
cock one last pump before placing them before his lips. With humiliation
staining his cheeks pink, Midoriya takes him into his mouth, sucking on the tip
timidly at first.
“That's not very nice,” Kirishima moans, thrusting slowly, and Midoriya feels
all kinds of affection for him in that moment. It emboldens him to take more of
Kacchan's cock in his mouth, meeting his eyes as he does so.
“Fuuuck~” Kacchan whispers, threading his fingers through Midoriya's hair,
tugging him closer. He takes him in his mouth until he feels the head at the
back of his throat, runs his tongue along the length. He tastes clean, fresh.
Precum on the back of his tongue is salty; he wants more of it.
Kirishima's fingers clench around his legs to hold him still, and he starts
fucking into him faster. Cock slides in and out wetly, thighs slapping ass with
each thrust. Midoriya's own cock bobs freely, aching and hard. Kirishima
murmurs in his ear.
“You're doing so well, Midoriya, taking us so nicely, thank you,” He kisses his
ear lobe, bites down, “thank you.”
He pops off of Kacchan with a wet sound, turning his neck to look him in the
eyes. “Kirishima...” He pants, one hand still pumping Kacchan while he shoves
his tongue into Kirishima's mouth, tracing the sharp points of his teeth.
His hand is wretched off of Kacchan's cock and confused he turns to him.
“Alright that's fucking enough.” Reaching down he takes the lube and pours some
on his dick, slicking it up from base to tip. His eyes flick over Midoriya's
head to meet Kirishima. “Get him up for me.”
The hands around Midoriya's legs seem to stiffen, go slightly rough, and when
he looks down he's shocked to see Kirishima has hardened the skin of his
forearms and hands, making his arms stronger and more immobile. He sits him on
his dick to the hilt and, holding him steady, stands up.
Midoriya is suspended in the air on nothing but Kirishima's dick and hardened
hands.
He holds his legs open and Kacchan closes the distance, lines himself up with
his already stretched hole. Midoriya's mind is steeped in a haze of lust.
“You should be fucking grateful for this privilege,” Kacchan says, pressing his
dick against the red rim, “Because you'll never have it again.”
Midoriya shuts his eyes, clamps his jaw shut. It's too much, the fit too tight.
He feels he's being stretched beyond his limit, but Kacchan presses forward,
pushes in with one hand clenching his hip and the other holding himself at the
base. He keeps going despite the resistance, and Midoriya feels the telltale
sting behind his eyes that warns crying is on the horizon, but then Kirishima
is kissing along his shoulders, tongue lapping the mingled sweat and water
dripping down the back of his neck. The gentle touch is enough to bring him
down from his panic momentarily, and he feels the head slip through.
And once the head is in, the rest of him is easy work to fit.
His hole is gaping, clenching around the too big intrusion, the knowledge that
not only is he getting fucked by Kirishima, but by Kacchan as well, he has both
of their dicks in his ass, two whole dicks-
He's wailing now, crying out variations of both of their names, unable to move
or do anything but take what they dish out. Once he's adjusted to the added
girth the pace picks up, Kirishima and Kacchan taking turns fucking into him,
Kacchan pinching at his nipples until they stand on end and ache. He leans
forward and kisses him, thrusting his tongue inside Midoriya's mouth and
swirling all around in a hurry. What's there to be in a hurry for? If he wants
to kiss him he can, whenever he wants.
He's starts to feel looser, used to the fullness, and his cries of alarm turn
into moans of pleasure. Every time Kacchan's cock slides in and out, it pushes
against a sensitive spot inside him, sending jolts of... of something through
him. He clutches uselessly at Kirishima's jagged arms, scraping his palms
against the hardened flesh and he claws at Kacchan's back in an effort to find
some semblance of control.
Midoriya's cock has been left unattended this whole time, and it's now that
Kacchan removes the hand scratching at his nipple and takes hold of him. He
pumps him in time with the dual thrusts and his cock dribbles down his length
making his own lube. Kacchan is glaring at him, his lips curled over his teeth,
grunting in exertion. He can feel Kirishima's hot breath tickling his nape, can
hear him huff out his own groans. The room is filled with the sounds of skin
slapping slick skin and a chorus of male voices nearing release.
His legs are trembling, shaking where they're held apart. The slide of cocks is
effortless now, the burn from the stretch having turned into a pleasant,
slippery sensation. He feels like he could go on like this forever without ever
growing bored of it, if it were not for the consistent press against the bundle
of nerves inside him, drawing him closer and closer to release.
A twist of the wrist on his cock and he's coming, spurting white hot over
Kacchan's chest, over his own torso, his entire body tensing and asshole
clamping down on the thickness inside him. He's vaguely aware he's screaming,
scrambling on top of them, Kacchan telling him to quiet the fuck down, but
before he can recover Kirishima is the next to go.
Midoriya feels it fill him up, hot and wet, mixing with the copious amounts of
lube, dribbling out of his hole. Kirishima stills then, allowing Kacchan to
move more freely, and every swipe from him works at Midoriya's overstimulated
prostate, milking him dry.
Finally, when tears have started sliding down Midoriya's cheeks and he can do
nothing but tremble helplessly in Kirishima's comforting embrace, Kacchan gives
one final shove and comes in him.
His fingers dig so deep into Midoriya's hip he knows it'll leave a bruise, and
for several moments it's just them, gasping for air, muscles sore and aching,
cocks gradually softening. When they slowly and carefully slip out of his hole,
they both help him down to his feet, but his legs have no strength left so he
stumbles, catches himself on the bench. The cum in his ass drips out and down
his leg. He feels fingers prodding his ass cheeks, separating them. His asshole
gapes automatically, searching for something to close on. Kacchan huffs
something like a laugh behind him.
A hand brushes through his hair and he looks up to see Kirishima smiling at
him, cheeks ruddy and chest heaving.
“It was good, right?” He asks, his optimism catching. Midoriya smiles in
answer, still trying to catch his breath. “Bakugou didn't think you'd want to,
but I knew we'd be able to convince you!”
“...Kacchan thought that?” He sits up feebly on the bench, bracing with his
hands. He looks over to where Kacchan is sitting on the opposite bench. He's
pointedly looking away, seemingly disinterested in the conversation. But that's
not how it really is, is it?
“Come on,” Kacchan says, standing slowly. “We should clean up and get out of
here before someone finds you all fucked out like that.” It's meant to be
ridiculing, Midoriya knows, but the way Kacchan's eyes linger on him, as though
trying to commit every detail to memory, tells him of something deeper there.
And when he goes over to assist Kirishima in cleaning him up, Midoriya thinks
maybe it's possible he'll get the privilege again, after all.
