Summary
     Kirishima was a spoiled, spoiled guy.
     The three of them had the gym to themselves, and, one thing leading
     to another had Bakugou and Tetsutetsu circling each other, a short
     few moments of suspended intensity before they clashed,
     simultaneously trying to get each other in a headlock, pushing
     towards each other with all they had.
     Really, Kirishima couldn’t have dreamed up a better view.
     (Barring what would happen after, the thing that had started this.
     Kirishima swallowed, throat thick with anticipation.)

Kirishima was a spoiled, spoiled guy.
The three of them had the gym to themselves, and, one thing leading to another
had Bakugou and Tetsutetsu circling each other, a short few moments of
suspended intensity before they clashed, simultaneously trying to get each
other in a headlock, pushing towards each other with all they had.
They had both foregone their shirts, wearing only gym shorts now, the excuse
something along the lines of how too much fabric would encourage cheating, get
in the way of correct gripping technique, giving Kirishima a close to perfect
view of every strain of muscle, every twist and push and pull, how their hands
urgently searched for purchase, any advantage that would break their deadlock.
Really, Kirishima couldn’t have dreamed up a better view.
(Barring what would happen after, the thing that had started this. Kirishima
swallowed, throat thick with anticipation.)
When he’d first brought up Tetsutetsu to Bakugou, asking him to consider, this
was not the ending he’d foreseen. He’d thought maybe, if he gave them time,
they’d both learn to tolerate sharing him. Maybe they would even be able to
hang out together sometimes, the three of them.
He hadn’t expected them to develop an instant appetite for each other.
Once something gave, it happened fast. A lost foothold, a lowered grip, and
Bakugou had Tetsutetsu on his stomach, one knee pressing into his back, an arm
wrenched up in a position that made Tetsutetsu grimace in pain, baring all of
his teeth, Bakugou showing just as many but out of the rush of victory.
Kirishima could see the quick rise and fall of their rib cages, the flex of
muscle in Tetsutetsu’s side as he tried to wrench his way out of Bakugou’s
grip, the way Bakugou’s arms and shoulders flexed and strained to keep the
other in place, how both of them were shining with sweat, this having started
at the tail-end of their evening workout.
Then Tetsutetsu managed to twist onto his side, then his back, releasing him
from Bakugou’s lock, and he bucked up his hip harshly with a growl, getting
Bakugou off balance, rolling them around, holding Bakugou to the ground with
both hands on his shoulders, straddling his waist.
Kirishima huffed out a quiet laugh to himself. That was a mistake.
Sure enough, Bakugou, with the flexibility that had overtaken Kirishima an
embarrassing number of times, got a leg up under Tetsutetsu’s arm, kicked at
his face, and when Tetsutetsu grabbed it to defend himself it meant he wasn’t
holding down Bakugou’s shoulder anymore.
This time, Bakugou didn’t hold back. Incensed by his close call with defeat,
the adrenaline, and, Kirishima found it likely, also by Tetsutetsu’s low near-
constant growling (in a different way), he went for a full body lock from
behind, wrapped his legs around Tetsutetsu’s waist, an arm hard around his
neck, the other under his arm.
Tetsutetsu’s face turned a dangerously dark red in almost no time at all, still
growling, Bakugou too, but refusing to activate his quirk because in this fight
that would mean a forfeit.
It wasn’t that either of them would mind ending up the loser, more that neither
had it in them to not do everything in their power to win. Especially, to
Kirishima’s mixed dismay and pleasure, when they went up against each other.
Tetsutetsu rolled over on his stomach, Bakugou still attached to him, then,
with a crescending shout, pressed himself up from the floor with one straining
arm and threw himself onto his back, Bakugou choking loudly at the loss of air
as he was crushed beneath him.
The surprise gave Tetsutetsu a valuable couple of seconds to twist around and
try to lock Bakugou down instead, this time not leaving anything to chance;
legs pinning down legs, hands pressing down on his wrists over his head, every
bit of his heavier frame pressing down on Bakugou, chest to chest, eye to eye,
Bakugou swearing and squirming and growling and unable to move an inch.
“I win,” Tetsutetsu pressed out, Bakugou still straining against him,
glowering, “surrender.”
Bakugou didn’t, thrashed as well as he could, bucked his hips, Tetsutetsu
parrying every movement, and Kirishima began to consider maybe suggesting they
move this to the dorms before it went any further, but then Bakugou stopped
struggling, fixing Tetsutetsu with a murderous glare.
“Fine, just get off me, heavy fucker,” he said, and Tetsutetsu pushed himself
off, casting Kirishima a slightly bewildered look at his snorting laugh.
“Good choice of words, dude,” Kirishima snickered, and Bakugou looked at him
sharply, apparently running the phrase over in his head because after a second,
he blushed from his ears to his neck. “Shut up!”, he hissed at him, his harsh
scowl not budging even a fraction. Kirishima just threw him his water bottle,
giving him an out from the conversation, and he caught it with one hand,
drinking deeply.
Tetsutetsu frowned at him. “Were you that sure you’d win? We could, I mean,
it’s not -”
Bakugou wiped his mouth with the back of his hand, glaring at the floor. “Fuck,
it’s fine. We’re all taking turns anyway.”
Kirishima felt the need to pitch in. “Yeah, but, it’s just a fun thing man, if
you don’t -”
“I said it’s fucking fine!” Bakugou turned his furious look at Kirishima, made
it easier to tell with the way that his face had gotten even redder and his
eyebrows twitched with the need to avert his gaze that this was embarrassment
more than anything else.
“As long as you’re sure,” Kirishima said, earnest, but then he couldn’t resist
giving the other a teasing smile, because it wasn’t often Bakugou got flustered
and yeah, he was going to enjoy this. “Trust me though. It’s awesome.”
That made Bakugou’s eyes turn away, and he shifted minutely, before abruptly
standing up and walking off towards the locker rooms. “Let’s get the fuck to
it, then.”
Tetsutetsu scrambled up from the ground, and Kirishima went for his water
bottle before they both hurried after him.
===============================================================================
They went to Kirishima’s room. They usually did.
Kirishima went straight to the floor to pull a small box out from under his
bed, took out the bottle of lube before he sat down cross-legged on his pillow,
tried not to jitter too much.
Bakugou held the same determination he’d had since the end of the fight, walked
over to the bed with the same efficiency as he’d taken his shower earlier,
pulled his black t-shirt over his head as he went, threw it on the desk chair
before roughly pulling off his pants and tossing them the same way. He looked
back at Tetsutetsu as he pulled off his boxers, making the other hurry to get
his own clothes off. After a moment’s consideration, Kirishima squirmed out of
his shirt as well.
They were still pretty new at this. Bakugou and Tetsutetsu, that was. Kirishima
could see the subtle stutters in how they moved, Tetsutetsu just standing there
for a fraction of a second too long, Bakugou taking a step forward instead even
though it took him further from the bed, his hand reaching for the other’s
waist but changing direction, taking a firm grip over the back of his neck and
pulling him down for a rough kiss.
Tetsutetsu placed a palm over Bakugou’s shoulder, thought better of it, let it
travel down to his back instead and press them closer together. He liked it
soft, but Bakugou didn’t trust that it wasn’t because he was considered more
fragile, yet. It had to be more like the sparring, and Kirishima was sure
Tetsutetsu didn’t mind, but it was yet another thing, another reason they
didn’t do this as often, usually preferring to use Kirishima as a buffer.
But it wasn’t because they didn’t like it. As Tetsutetsu went around Bakugou to
sit down on the bed, back towards Kirishima, his arousal was clear, and Bakugou
was no exception, Kirishima getting a perfect view as he went to straddle the
other.
It went better as they got more into it, both better at communicating with
their bodies than their words. They ran their hands over each other, refused to
let the kisses turn soft, growled and grunted into each other’s mouths, Bakugou
grinding lazily into Tetsutetsu.
Kirishima didn’t want to touch himself, didn’t want to be distracted for even a
second, even though he already ached.
This was just the second time they did anything like this. First had been last
week, and it had been Kirishima taking them both, one at a time. Bakugou first,
a little bit because they’d been together longer and a lot because Tetsutetsu
was slightly bigger. It had been amazing, soft and slow, face to face because
he’d already practiced a bit on his own, and he could barely wait to try it
again, but because of what they’d decided he was gonna have to, at least for a
little while.
It had begun as a joke, and in a way he guessed it still was, all the possible
combinations they could do it, so many firsts. It was Kirishima who had said
that maybe it would be a fun thing if they all popped a cherry each. He hadn’t
expected the others to agree, especially not when they’d already both been his
firsts, making the game moot before it even began.
He definitely hadn’t expected them to literally fight about who of them would
top the other, leaving the winner to be topped by Kirishima, completing the
game. And then they could try doing more stuff together all three, at the same
time, because they hadn’t quite figured that out yet.
He couldn’t wait.
It hadn’t been long, but Bakugou broke off from Tetsutetsu, pushed himself off
with a hand to his chest. “Move.”
Tetsutetsu awkwardly shuffled to the side and towards the end of the bed as
Bakugou got on his knees, reached a hand towards Kirishima who placed the
bottle of lube in it. Another pause, short enough that Bakugou probably didn’t
think Kirishima could even notice, before he passed it over his shoulder.
Tetsutetsu took it, but that was it.
There was no way any of them didn’t notice this awkward silence. Both Bakugou
and Tetsutetsu looked at Kirishima, but he just smiled at them, because this
was between them, this time, and placing him in the middle would defeat the
purpose.
They could do that later.
Tetsutetsu was frowning, Bakugou glaring.
Kirishima was. Not. Gonna make this smoother. He chewed on his lip to keep his
mouth shut.
Bakugou scowled at him, huffed, and twisted to look at Tetsutetsu. “The fuck
are you waiting for?”
Tetsutetsu’s frown turned into a look of exasperation. “You!”
The following stutter was filled with Bakugou stopping himself from saying
something, his slowly spreading blush reaching his collar bones before he
turned forward again, placed his elbows on the bed and spread his legs. “Do you
need a fucking guided tour or do you think you can handle it?”
“You really offering?”
Kirishima stifled down a laugh as Bakugou’s ears turned even redder.
“Just – Fuck! Just fucking do it already.”
There was the click of a bottle opening.
Although Kirishima had prepped himself last week, they’d messed around with
lube a few times, so Tetsutetsu knew to take a lot but not too much, to spread
it over his fingers and let it sit a moment to heat it up.
Kirishima couldn’t see exactly what Tetsutetsu was doing from where he was
sitting by Bakugou’s head, but he didn’t really need to, not with how Bakugou’s
breath hitched at the first tentative touch, how he moved back impatiently,
trying to stay in control by making sure no one was ahead of him, even here.
Not that he needed to, not with how wary Tetsutetsu got about things like this,
always so very careful not to hurt anyone.
But he’d begun to see that it wasn’t cuts and bruises that hurt Bakugou most,
and he realized, Kirishima could tell, that Bakugou probably needed this to
move fast, couldn’t handle both being in a vulnerable position and
simultaneously being treated as if he was.
So he pushed in, Bakugou gritted his teeth and held his breath, Tetsutetsu put
a hand on his hip to remind him to relax, Bakugou shifted his head as if to
glare at him but couldn’t turn around far enough, Tetsutetsu pushed further and
Bakugou’s head fell, shoulders hunching.
“Alright?” Tetsutetsu asked, voice rougher than before, eyes trailing from
where his hand was slowly moving, up Bakugou’s tense spine.
Bakugou didn’t answer, until Tetsutetsu stopped moving. “Fucker, yes, alright,
now fucking pick the pace up or Kirishima gets to do it.”
Tetsutetsu pulled out then, and Bakugou drew in a breath, probably to shout at
him but then the bottle cap clicked open again and he clamped his mouth shut.
Two was better than one, (Kirishima was well aware), but Bakugou wasn’t as used
to it, had mentioned after last time he didn’t really do this by himself, so he
tensed up again, needed a few breaths to get used to it.
But then, he did. The tension between his shoulder blades became less, his head
swayed slightly, his breaths became deep and open-mouthed. At the first moan
Kirishima almost echoed it, sucked his lower lip into his mouth to stop it, bit
down.
“Y - ” Bakugou drew in a quick, deep breath. “More.”
The bottle was ready this time, Tetsutetsu barely needed a pause to coat his
fingers again before pushing back in with more confidence, moving his arm more
as he tried to find that spot.
“Fuck!!”
Bakugou pressed his forehead into the mattress, clenched his hands in front of
him.
Tetsutetsu wasn’t one to shy away from a winning strategy, kept pressing in at
that same angle over and over, making Bakugou switch between gritting his teeth
together, refusing to make a sound, and moan loud enough to be heard through
the floor.
Kirishima couldn’t tell if he was getting close, because this was all new. The
ragged breaths, how he’d already begun to glisten with sweat without even
moving. Sure, Bakugou always worked up a sweat ridiculously easy because of his
quirk, but, this was something else.
It was amazing.
“Fuck me already, you – hah – lazy fuck,” Bakugou gritted out, and it was
followed by almost a shout as Tetsutetsu thrust his fingers into him harder.
But he knew not to stall, not with Bakugou as worked up as he was. He didn’t
allow himself to need often, but when he did, the other two better act with
nonchalant urgency or his defenses would catch up with him. Tetsutetsu had
learned this particular thing the slowest, but he had learned it, which was why
this wasn’t a horrible idea.
There was nothing, really, that Bakugou needed to learn about Tetsutetsu, more
things he’d hopefully notice that could come to his advantage. Like how his
insult had made Tetsutetsu’s breath hitch, how his demanding and slightly
demeaning way of talking, combined with the rest of his loudness, was the main
reason for Tetsutetsu’s slight flush and blown pupils.
Tetsutetsu ran a hand along the crease of Bakugou’s hip, stroked his lower
abdomen, teasing, not reaching for his leaking hardness, making his movements
stutter, body unsure if it should move back into Tetsutetsu’s right hand or
forward in appeal to his left.
“Want me to wrap it up?” Tetsutetsu asked, voice low.
“What the fuck?!” This time Bakugou twisted his spine enough to catch
Tetsutetsu with a withering glare. “If you stop, I’ll fucking kill you.”
Tetsutetsu gave him an amused sawtooth grin, made his body shudder with another
thrust of his fingers. “I mean a condom.”
Bakugou turned back towards Kirishima, met his eyes before turning his head
halfway back again. “You fucking better.”
Seeing as they were both.. occupied, Kirishima took this as his cue to shuffle
off the bed, adjusting himself as he went, to pull out the box under it again,
this time grabbing a couple of small square packets. He shoved one in his
pocket and carefully opened the other, moving to rest his knee on the bed next
to Tetsutetsu.
He’d been so focused on Bakugou, because he’d been louder, closer, filling all
of his senses, but, Tetsutetsu was definitely worth noticing, lips almost kiss-
swollen from how he kept chewing at them, eyes dark, his cock curved upwards,
head flushed and glistening.
He looked absolutely irresistible, and so Kirishima put a hand on his neck and
pressed their lips together, Tetsutetsu kissing him greedily, all hot tongue
and sharp teeth.
Kirishima broke it off with a final nip and lick of his lower lip, then pulled
the condom out of the packet, pinched the tip of it before sliding it down
Tetsutetsu’s length easily, having the technique practiced from doing the same
to his toys countless times.
It wouldn’t hurt if he helped with the next step, too. He picked up the bottle
of lube from the bed, met Tetsutetsu’s eyes as he put some in his hand, and
spread it over the condom with slow, firm movements, making the other bite his
lip again. Kirishima coaxed his mouth open with his own, gave him something
else to bite.
“I’ve changed my fucking mind, Kirishima, where are your toys. They don’t get
distracted,” Bakugou growled out, having sat down on his heels, glaring at them
both reproachfully.
“Sorry, I couldn’t resist,” Kirishima said, completely unrepentant, and put a
hand on the bed so he could reach to kiss Bakugou instead. “I’m gonna behave.”
He slipped off the bed, went back to his position in front of them, kissed
Bakugou again, softly, to ease the last of the frown off his face, while
Tetsutetsu supplied himself with more lube.
“Okay, ready?” Tetsutetsu asks, and Bakugou, so far beyond the end of his
patience, yells back; “Do you need it in fucking writing?”
Tetsutetsu’s face darkens, either because Bakugou is getting on his nerves or
making him painfully turned on, probably both, and now he doesn’t hesitate and
he positions himself and pushes in slowly.
Bakugou makes a choked sound like he’d been punched in the stomach, and there
was a quiet, sparse crackle coming from the hands he’d balled into fists in
front of himself again, wrists slightly curled to keep the heat away from the
sheets.
“Tell – Tell me when you’re ready.” Tetsutetsu was breathing heavily through
his nose, jaw clenched tight, both hands gripping Bakugou’s hips hard enough to
bruise.
There was a pause, the events finally at a pace that made Bakugou slow them
down, slowly getting back in control of his breathing and his quirk.
“Yeah,” he said, the end of the word being choked off, Tetsutetsu having
already begun moving, abusing his lips with his teeth again before falling
forward, pressing sloppy kisses onto Bakugou’s back.
Kirishima recognized the tempo from last time, when it had been him, and those
kisses had been both given and received. He really, really, looked forward to
the next time. It had been amazing.
Bakugou didn’t seem to agree.
“I’ll - fucking – fall asleep - like this,” he grunted out between thrusts, not
sounding credible in the least. Tetsutetsu stopped kissing him, grabbed his
hips again, snarled as he began moving faster.
He must be hitting that spot again, because Bakugou was almost shouting at
every thrust, his hands beginning to crackle dangerously, and Kirishima grabbed
them with his own hardened hands so Bakugou could forget about the sheets.
But it seemed he’d instead reminded Bakugou of his presence, because he grabbed
Kirishima’s wrist, then his shoulder, wrapped the other arm around Kirishima’s
neck and tried to kiss him. It was sloppy, uncoordinated, because Tetsutetsu
was still fucking into him and he couldn’t keep steady. He settled for moaning
into Kirishima’s neck instead, hands scrambling over his hardened back,
Kirishima’s own arms under his, holding him up.
This was nothing like the other times, Bakugou was nothing like the other
times, so completely lost in it, so desperate, needy.
“Fuck, I’m - so close - Ei -,” he panted out against Kirishima’s neck, and
Kirishima scrunched his eyes shut so he wouldn’t come in his pants, moved his
right hand down from Bakugou’s upper back, down along his side, to grab his
cock, spreading the precome over the head before jerking it hard, fast.
He could feel the explosions increase in force against his jagged back, could
hear Bakugou’s moans rise in pitch as Tetsutetsu’s got louder, heard the sound
of skin against skin increasing in pace until finally, Tetsutetsu stiffened and
stuttered, pressed his forehead against Bakugou’s shoulder, Kirishima working
Bakugou over in a frenzied pace for another breath until he spilled over his
hand with a shout.
He quickly switched hands, held Bakugou through the aftershocks and he shoved
his dominant hand into his own pants, not needing more than a couple of come-
slicked strokes before he came with a shudder, moaning into the heated skin
where Bakugou’s neck met his shoulder.
Bakugou slumped against him, Tetsutetsu following, their combined weight
pressing his back against the wall. Bakugou made a small sound of discomfort
into his ear, probably as Tetsutetsu pulled out, because the next moment the
tied-up condom was tossed into the trash can.
“Hey, move over,” Tetsutetsu grumbled as he tried to fit in between Bakugou and
the wall, pushing the other two towards the edge of the bed just by wiggling
into place.
Bakugou didn’t look pleased at all when Kirishima gently pushed him away to
scoot off the bed. He grabbed the pillow to shove under his head and arms as he
went to lie on his stomach. Tetsutetsu let one arm fall heavily over his back,
and it was unclear if it was out of affection or because of the lack of space,
but Bakugou didn’t protest.
Kirishima pulled his pants off, then his underwear, using them to wipe at the
mess that was still sticking to him before grabbing a fresh pair from his
closet and putting his pants back on.
He wanted to lie down on top of them, mix breaths and heat and sweat, but
they'd come directly from training and even he felt a bit weak, knew the other
two were worse off.
“I’ll get you some water or something, a snack,” he told the two on the bed who
were too out of it to answer with more than a pair of hums, before he pulled
his t-shirt back on and headed out the door.
He checked his hair in the elevator mirror, pleased that it didn’t quite need
to be kept up with a headband, even though it did droop slightly.
Kirishima was surprised to find Kaminari in the kitchen, especially alone,
fiddling with his phone and only giving him a nod of acknowledgment.
It wasn't until Kirishima was head deep in the fridge, looking for something
that would be palatable to all three of them, that he decided to speak up.
“Well, you guys sure had a good time," Kaminari said, tone lightly teasing.
Kirishima could feel his face flush, felt a little bit let down by the chill
from the fridge, knew it wouldn't cool his face down in the second before he
had to turn around and look at Kaminari, smiling down at his phone.
“Um.”
Kaminari continued, not dissuaded in the least by his lack of coherent
response. “Or, well. I know Bakugou did.”
“How - “
“Your floor is not as soundproof as you imagine it to be, bro.”
Kirishima winced, bared his teeth, really wanted to hide his face in the fridge
again.
“Oh." He cleared his throat. "Sorry.”
Kaminari looked up at him, and Kirishima could immediately tell how feigned his
casual air was from the glint in his eyes, even as Kaminari waved him off with
a smile.
“No, it’s fine! Really. That’s the most action I’ve gotten in a while. I
could’ve done worse,” he said, getting a far-away look. Then he blinked, seemed
to consider if he should continue for about a second, which was way more time
to think than he usually gave his words but apparently still not enough because
then he said; "What did you do to him?” with a look that was a little bit too
intrigued for it to just be a random question and Kirishima had never really
noticed this before. Sure, Kaminari looked at Bakugou sometimes, Tetsutetsu
too, probably even him, but he looked at everyone so Kirishima hadn't really
thought anything of it.
“Uh. Wh – Why’re you asking?” He tried to act cool, took a glass from one of
the cupboards, began filling it with water.
Kaminari leaned back in his chair, folded his hands and rested them on his
stomach. "Because," he said, and that was as far as he could stretch the
unaffected air because in the next moment he swung forwards, rested his head in
a hand supported on the table instead, "from what I could hear, it sounded like
a superb concept. I’d ask for a demonstration if that wasn’t like, really
weird."
Kirishima did not know what to say, so he took a sip of water. But apparently,
Kaminari did. Or at least, he didn't stop talking.
"Please, humor me. I live vicariously through your ripped, dreamy, albeit
somewhat unsettlingly ferocious conquests.”
“Uh, I. I’m not sure they’d want me to talk about it.”
A flash of disappointment flew over Kaminari's features, but he schooled them
swiftly into an easy smile.
“Completely understandable. I’ll just, imagine something. Employ the help of
Spark Plug and Lightning McQueen," Kaminari said, making a demonstrating finger
gun with his left hand, followed by his right. "Don’t worry, we’ll get to the
bottom of it," he concluded with an exaggerated wink.
Kirishima choked on the water he had foolishly taken another sip of while
Kaminari was talking.
“Too much? Shame; I don’t care, I had to listen to Bakugou make angry porn
noises for so long I actually had to go down here to take a breather." Another
pause, but apparently Kaminari had decided to go all in, tonight. "If a
position ever opens up in that thing you’ve all got going on, hit me up.“
“I -” I can't tell you anything without checking with the others first,
Kirishima wants to say, can't even tell you I'll ask them, because we've
decided to talk to each other first before even hinting to anyone else there
might be interest so nobody gets accidentally strung along. But he couldn't,
because that would kind of mess up the entire concept.
He didn't have time to come up with something to say before Kaminari held up
both hands in surrender.
“Kidding, kidding!" He lied easily, with a laugh. Seemed to notice Kirishima
noticed, tried to smooth it over. "Hey, on a completely unrelated note, you
don’t happen to have anything left of that tub of peanut butter ice cream I saw
you with last week?”
It was better he just left it, acted like the diversion had worked.
“Yeah, sure, it’s in the freezer, knock yourself out." He opened the fridge
again, pulled out a bunch of peaches, balanced six of them on his arm. "I'm,
uh, gotta go back.”
Kaminari got up from the table, bumped his shoulder as they walked by each
other.
“Great, thanks! Have a great evening, now!"
Even though that was nowhere near the most suggestive thing Kaminari had said,
Kirishima still couldn't help but blush again.
===============================================================================
He hadn't closed the door properly, so he could hear his boyfriends' voices
carry through the corridor, and he began walking more quietly, curious if he
could sneak up on them, curious about how they talked when he wasn't around.
“- ..yes, the first one was watchable, but I’m telling you the sequel is shit,”
he heard Bakugou say, sounding exasperated but in that way that said he was
enjoying himself at the same time.
“How could it be shit, it’s the same production team as the last movie!”
“The plot makes zero fucking sense! She died in the last one!”
“So? It’s the fight scenes that are the point!”
Kirishima leaned against the door, making himself known. They'd both put their
underwear back on, Bakugou also wearing one of Kirishima's t-shirts, their legs
thrown over each other as Bakugou leaned against the wall by the pillow and
Tetsutetsu against the other.
“You - “ Bakugou's voice cut off as Kirishima came into view.
“I’m back!" Kirishima chirped at them, threw them both a peach, put the three
extra ones on the desk. "What are you talking about? Wanna watch a movie or
something?”
Bakugou and Tetsutetsu glared at each other, and Kirishima was still amazed by
how much they enjoyed butting heads. After a few moments, Bakugou let out a
small huff.
“No, we’re just discussing if we’re gonna watch the sequel to the one we saw on
Thursday," he said, voice low and challenging. Kirishima grins.
“Oh, we should! I loved those fight scenes.”
Tetsutetsu was facing away from him, but he could still see the edge of his
wide smile. Bakugou's glare shifted beyond him, became directed at Kirishima,
but Kirishima just kept grinning at him until Bakugou relented, bit angrily
into his peach instead.
Kirishima sat down on the bed next to Tetsutetsu before taking a bite of his
own fruit, swallowing it before he spoke. “So, uh. Kaminari.”
"Yeah? What about him?" Tetsutetsu asked, mouth full.
"He was in the kitchen. He, uh. Kind of heard."
Bakugou barked out a laugh. "Was he jealous?"
Kirishima took another bite before continuing. "Uh, yeah, I actually think so?
Of me, because of, uh, you two. I think," he said, and looked at the others for
reactions. Tetsutetsu looked almost bashful, while Bakugou's face held a
predictably self-satisfied smirk.
"So I wanted to tell you, that you should maybe consider it. Him. I mean, I
don't think he's actually interested in me coming along, but it's fine by me if
you two wanna try, see if he really meant it. I think he did, but."
Tetsutetsu looked at him, then at Bakugou, then back to Kirishima with a shrug.
"I mean. I'm game. He's pretty, and fun."
Bakugou didn't reply, just kept eating his peach with a frown.
"Think about it, yeah?" Kirishima said, before dropping it. Because, Bakugou
would. What felt like ages ago now, back when Kirishima had first brought up
what he suspected was his mutual interest in Tetsutetsu, Bakugou hadn't given
him an answer for a week, and Kirishima was almost sure he'd forgotten about it
or decided he'd pretend Kirishima had never asked when he finally agreed to try
it.
They finished their peaches, and the second round, were all too tired to study
or even watch a movie so they pulled Kirishima's mattress off the bed because
it was easier (and less risky) to try to fit them all on the floor.
Tetsutetsu and Kirishima lied down side by side on their backs, with Bakugou
sprawled on his stomach on top of them. It wasn't the most comfortable sleeping
arrangement, but Kirishima loved it anyway, loved hearing Tetsutetsu's
breathing slow down next to his, have Bakugou shuffle and grumble on top of
them, actually inordinately pleased he got to use them both as bedding.
It worked for a while, but then Bakugou squirmed down between them, basically
forcing them on their sides for all of them to fit, wrapping his arms around
Kirishima's waist and, probably, not that Kirishima could tell in the dark, get
enveloped by Tetsutetsu in turn.
They settled down, Bakugou hot as a furnace behind Kirishima's back and
probably very content with that fact, heated arm around Kirishima's waist
sneaking in under his shirt, heated breath soothing on his neck.
Bakugou was quiet, still, would've seemed like he was drifting off to anyone
who didn't know that was something he wasn't usually this subdued about. And,
sure enough.
Bakugou spoke softly, but loud enough in the quiet room. "Hah, if we did go for
Pikachu, I bet he'd turn into an incoherent mess in less than a fucking
second."
Kirishima snorted. That was probably true, actually.
"… You think?" Tetsutetsu asked, the low volume of his voice no disguise for
the strong note of interest.
"Obviously, with how he gets from just using his own quirk." There was a pause.
"I bet he could use that in more interesting ways than he does during
training."
Kirishima heard Tetsutetsu shuffling a bit. "We'll have to try it out, then."
Bakugou grunted, a yes by his standards, before they fell silent again, the
warmth of Bakugou against him and the sound of everyone's deepening breaths
enveloping Kirishima in a calm happiness he'd never thought he could have.
Tetsutetsu was already snoring softly behind him, Bakugou not far behind from
how slowly the hot air lapped at his nape in waves. They'd moved forward,
today, and nothing had changed, in the best way, and Kirishima didn't know how
he'd gotten this lucky.
And maybe not tomorrow, but probably some day soon, these two amazing people
would take their common love of a good challenge and direct their thirst for it
towards someone new, and Kirishima had no idea what would happen next but he
was sure it would be something good, because as long as the two of them were
with him, it always was.
Kirishima could imagine it easily, Tetsutetsu and Bakugou, honing in on
Kaminari like a pair of hungry wolves, the surprise on Kaminari's face when he
found out they'd rather lap at him than bite, were only as rough as they were
asked to be.
He couldn't wait for them to tell him all about it.
