Notes
     I just
     I just bullshitted this whole thing
***** Chapter 1 *****
Bakugou's nails are long, sharpened like claws. His build is slimmer than
Kirishima's, made to take and deal blows just the same but there's something
about it. Something made for a little more gracefulness than what he used on
the battlefield.
At first, like the absolute idiot he is, Kirishima mistakes it for a secondary
sex characteristic. Which doesn't even make sense five minutes after he thought
it because Bakugou's shoulders are broader than most of the people in the class
save for a few. But they just have this certain way they roll, even with all
the strength and danger that lay behind them, there was just something there.
It takes Kirishima exactly two months to realize what it is.
Bakugou was cat like. But still held so much power it was a bit like fumbling.
It looked rough and brutish, like he didn't fit in his own skin quite yet, like
something was pushing through and couldn't get out and that Kirishima could
understand.
Most people with quirks could shift into certain creatures. Some quirks were
different forms of shifting, some people were already creature-like in
appearance and didn't require shifting. And then were the quirkless that didn't
shift at all. Though on the rare occasions there were people with quirks that
couldn't shift at all either, like Uraraka.
But those who could shift typically shifted into creatures smaller or equal in
their size.
And then some of them shifted into creatures too large for their bodies.
Kirishima, for example, shifted into a wolf that was far too large to be a
normal one. Wolves were pretty common, and are said to be some of the first
shifters, and the bigger the wolf the closer one is to the first shifters.
However, in his human form, it felt like he was wearing ill fitting clothes,
too tight for his body. He felt like he needed to rip himself to shreds and let
the wolf out. But not many people took well to his hulking form and he didn't
want to take up too much space indoors anyway. Not practical.
Was that why Bakugou looked like that? Looked like he should be walking tight
ropes but also looked like he was bound by ropes instead?
It took Kirishima longer to realize none of them had seen Bakugou shift.
Those who could shift had shifted at least once in class. Stretching out their
animal forms when they felt they wanted to, showing up to class in said forms
at times. They used them during combat training, Kirishima himself had posed as
a villain in his wolf form so the others could practice tactics against large
shifters that they could meet in the field as pros.
But Bakugou had never done it.
Now, while Kirishima didn't know all the struggles of trans individuals because
he wasn't one and he wouldn't even pretend to know what it was like and he'd
sooner shut up and listen and comprehend than speak for them or over them, he
knew some things.
Like how some trans people who shifted, shifted into animals that had very
telling characteristics as to what genitalia they had. Roosters with their
crests and chickens with their lack of, peacocks with their tails, cows and
utters, things like that. And they avoided shifting because of it. Well some,
others didn't care. It was each person's journey and he wasn't going to pry.
Except he really, really wanted to see Bakugou shift.
It was more of a need, really. It had been a while he had met a shifter too
large for their human bodies, and while his was only a theory, the idea that
Bakugou might be like him brought him a little closer to the boy. Made his
heart flutter.
So he asks Midoriya.
"Oh I've never seen him shift." Is the answer Midoriya gives and his jaw drops
in surprise.
"You've known him since you were four!" Kirishima puts a hand to his chest,
honestly shocked anyone could keep their secret for that long.
Midoriya shrugs, currently taking down notes of all of their fighting styles
and putting Kirishima down on his "greatest threats" list, right under Todoroki
and Bakugou. He doesn't know if he should be honored or not. "Maybe it's
personal for Kacchan? We weren't really friends, sorry Kirishima."
And this was what Kirishima feared. That, as Bakugou's friend, he would have to
ask him. Now, he loved Bakugou (as a friend. Just a friend. Nothing more. Yup.
Totally platonic what are you talking about.), but he didn't know if the
feeling was reciprocated. If Bakugou even considered them friends at all, or if
he would be prying too much and end up pushing the boy away. Their dynamic was
pretty set, Kirishima understood Bakugou's special brand of social interaction,
but there was always that doubt of "When he says he hates me, does he mean
it?", though he never actually said he hated him, now that he thought about it.
Only one way to find out.
Kirishima pulls him away during practice, careful to find a spot far away
enough for no one to listen in but close enough for Bakugou not to get too
suspicious of his intentions. It's not that odd for him to do, and Bakugou goes
with little complaint, only cussing him out twice which was a feat on its own.
But the nerves eat at Kirishima, he was breaking their dynamic. He was asking
for honesty when he just took to translating Bakugou's rage and brutish ways
into what he was actually feeling. He didn't know if Bakugou was ready to be
vulnerable, if this was even a sensitive subject at all.
"Why do you never shift around us?" He finally forces out. It's all in one gush
of breath, cheeks flaring red when he realizes that he said that a little too
fast, staring at the raised, unimpressed brow Bakugou is sending his way.
"I'm too big for the building. Wouldn't fit through the doors." Bakugou shrugs
and okay yeah. That was a lot easier than he thought.
Kirishima blinks, taken a back, looking at the extra large doors made to
accommodate all shifters and all quirks, then looking back at Bakugou's taller
yet just the tiniest bit slighter form. "Really?"
"Really." Bakugou shrugs again, not at all uncomfortable so that answered that.
All of his theories so far had been a bust save for the larger form theory.
"You could always shift here and then shift back?" Kirishima suggests a little
weakly, still reeling.
"I know basically everyone has seen me naked at least once but the idea of the
teachers seeing me naked is kind of fucked up to me." The blonde replies but he
seems to be thinking it over anyway. "If I could change out of my clothes and
leave them nearby to get dressed again maybe."
And then he's stripping, right there, in front of Kirishima. And okay, they've
been in locker rooms together. Mineta had drooled over Bakugou more than once
only succeeding in getting the threat that he'd have each ball on his head
ripped off until he bled out if he so much as blinked in his direction again.
Kirishima stared at his backside more times than he could count. But for some
reason, the idea that Bakugou was doing this because he suggested it and that
he was finally going to see his creature made it... intimate.
Bakugou's sports bra hit the ground and then he was crouching low, kicking the
clothes away and to the side before motioning with his hand for Kirishima to
step back. "Make sure I don't step on that useless grape pervert." And then he
was shifting.
Now, the act of actually shifting was disgusting to hear and look at. It was
cringe worthy. Bones moving unnaturally beneath skin, the popping sounds of
them rearranging and lengthening, reshaping into the skeleton of the creature
they would become. It was even more displeasing when the creature was
freakishly large. More pops and cracks and grinding. It made it louder, and by
now the class must have been aware of what was happening. Typically, one would
look away when someone is shifting. Not out of being polite, but because it was
just truly the most disturbing thing in the entire world and made most lose
their meals.
But Kirishima really couldn't look away.
Vaguely, he hears someone telling him to knock it off and yeah, they must have
thought he was the one shifting because of his size, must not have been looking
because soon enough Kirishima finds himself staring at the most intimidatingly
large creature he could ever imagine.
A tiger.
A white tiger.
Now, he knew better than anyone that people who shift didn't always shift into
animals that could pass off as the wild animals they resembled. There were
hardly any ten foot tall wolves in the wild.
But this was.
Fucking ridiculous.
His jaw hit the floor looking at Bakugou's shifted form, who stretched as if it
had been so long since the last time he'd done it.
It probably had.
Who would have enough space for that?
He could hear the class gasping behind him but he didn't care. Kirishima looked
down at the ground and realized he was on his knees. Funny. When had that
happened?
"Oh my god." Someone whispered.
That someone was him.
Aizawa had made his way over, Toshinori on his tail with a much more excited
step but Kirishima was still on his knees because good lord no wonder Bakugou
carried himself like a god amongst men.
He fucking was one.
Bakugou plops down onto his side, finding enough space on the flat surface to
do so without something jabbing into his side at the same time as Aizawa and
Toshinori stop close to his claws.
"I don't get paid enough for this." Aizawa starts at the same time Toshinori
says, "Bakugou, my boy, this is amazing!"
Bakugou made a chuffing sound, turning over onto his belly and keeping his head
low to look at everyone, "What's so amazing about it? I'm a big fucking cat.
I'm only a little bigger than Eijirou."
Kirishima chokes. They were using their first names now? This entire thing was
too much for his heart that was beating out of his chest as they spoke.
Midoriya is on his knees next to him and Kirishima wants to turn around and
make a joke of it. 'Welcome to the club', something like that, but he's still
choking on his breath and Bakugou is fucking grooming himself in front of them.
He's going to die.
"My boy, you're massive." Toshinori says seriously, like Bakugo doesn't already
know, towering over them as he is.
Aizawa runs a hand down his face and grumbles about wanting his sleeping bag
for a moment before turning back to Bakugou. "Would you like to play as the
enemy today so the others can learn to handle larger opponents?" He then points
toward Kirishima, "He can join you and do the same."
Kirishima would give anything in the world to be shifted next to that
breathtaking creature. He nods his head quickly, a little too excitedly.
Bakugou's slowly smirk on his catty face is ten times deadlier than it had ever
been and he could blow up anything he wanted with his bare hands. It was
possibly the manliest thing Kirishima had ever been blessed enough to see. "I'm
stepping on Deku's puny ass."
"Please no." Midoriya squeaks next to him and Toshinori looks ready to object
but Aizawa just pulls Kirishima up by the collar and pushes him towards the
tiger.
"Shift, stop wasting my time."
***** Chapter 2 *****
Chapter Summary
     Sometimes, when Bakugou was particularly excited about something and
     was too caught up in it to catch himself, he'd turn around and nip at
     Kirishima playfully, coax him into a roll around the ground,
     terrifying people around them as two creatures, upwards of ten feet,
     seemed to wrestle and test who could pin down who.
Chapter Notes
     Alright I'm continuing
After Bakugou's first shift in front of the others, the class had quickly
gotten used to him shifting often around them. Stripping down just about
anywhere, folding up his clothes in a pile and then moving to let the
transformation race through him in a flurry of cracking bones and stretching
skin. Most of the class had gotten used to the sounds, able to stomach it a
little better now that they had heard it so many times, and Kirishima had
gotten used to staring as if it was a train wreck and he couldn't look away.
It sounded like one at least.
And Kirishima has taken to shifting with him.
Which, of course, meant there was less and less space for the both of them but
if Bakugou minded he didn't say, so Kirishima kept doing it.
When they went off to open fields or exceptionally large stadiums, that was
when Bakugou really flourished.
He lit up like it was all he ever wanted, similar to when he'd pulled the pin
during his fight with Midoriya. But less of murderous glee and more of genuine
happiness, stretching out as if his entire being had been waiting for it.
Bakugou lost the initial shyness of stripping down in front of strangers and
now did it easily. Everyone around them gave indignant squawks but as if he
would care when he was a god gracing them all.
His shift would ripple through him and then he'd be bounding off to enjoy his
freedom, Kirishima on his heels.
Children would always stop and stare, surprised at two massive creatures
flipping through their parks and streets as if they weren't monstrous in size
and beauty, though Kirishima considered a red wolf would never be as impressive
as the white and black striped pelt of the Bengal tiger that allowed him to
even interact with him.
Sometimes, when Bakugou was particularly excited about something and was too
caught up in it to catch himself, he'd turn around and nip at Kirishima
playfully, coax him into a roll around the ground, terrifying people around
them as two creatures, upwards of ten feet, seemed to wrestle and test who
could pin down who.
Kirishima only managed to pin Bakugou down twice out of the countless times
they had play fights. And it always felt like the tiger let it happen, rolling
over to appease the wolf in Kirishima. Which, from anyone else, would piss him
off, but from Bakugou it was such a considerate move it made his heart swell.
Like now, as they rolled and Kirishima caged Bakugou's larger form under him,
staring down at the panting tiger's face who seemed to understand what the wolf
needed out of him. Tigers didn't submit the same way wolves did, but Bakugou
knew better than a tiger and he went against his nature easily, chin tilting
upward to expose his throat for him.
Usually, that's where they left it. They'd hop away from each other and that
was it. But Kirishima liked crossing the imaginary lines in the sand with
Bakugou, peeling away his walls so carefully so the blonde wouldn't pull away
and build those walls higher, stronger, make it harder for the next person to
peel it away and save him from his own personal hell. It was careful, it was
planned.
Kirishima lowered his head slowly, jaw open, soft growl like a purr in his
chest as he gently pressed his teeth around Bakugou's throat.
For a little bit, nothing happened, but then Bakugou was limp under him, his
own growly purr answering his and Kirishima almost buckled under the emotion
that flooded him. Bakugou Katsuki had given him such a precious gift.
His trust. Trusting him with his entire life.
Kirishima slowly pulled away and Bakugou stared back at him, almost expectant.
"You-" Kirishima began but choked on it, moving to roll off of the other who
easily moved onto his belly, looking back at him and waiting. "You trust me
that much?"
Bakugou huffed but there was amusement in his eyes. "You're the only one immune
to my shit, you trust me not to kill you, I trust you the same."
To anyone else, that would have made their hope dissipate but instead it made
Kirishima's hope blossom. He knew what that meant in Bakugou's own special way.
Because he knew Bakugou.
It meant he cared for him more than he cared for the others. It meant he
respected him just the same as Kirishima respected him in return. It meant he
considered Kirishima an equal.
It was hard to process that. Kirishima had spent so long trailing after
Bakugou, honored that the other who was so distant from the others allowed him
so close, that the idea that Bakugou might see him on the same level as him was
almost too good to be true.
It took months to get used to the new power dynamic. He didn't do much with his
new found ability be on Bakugou's level at first, but after a while he quickly
got used to actually speaking and discussing things with him, telling him what
he thought was wrong.
It was going well, but as always not everything is perfect.
"Deku, if you want to live, get away from me right the fuck now." Bakugou
warned one day as he walked into the class room. Midoriya had been at the door,
discussing something or other with Iida Kirishima didn't really hear, but the
deadly calm way the words left Bakugou's mouth made the entire class turn
slowly to look his way.
"Ah, sorry Kacchan-"
And that was it. Kirishima winced, knowing what was coming before it came.
Midoriya was pinned up against a wall before he could even breathe and one
could see the way Bakugou's skin moved and pulled at itself, desperately
holding back a shift.
"Bakugou!" Iida exclaimed, ready to rush off to a teacher for help but to his
and everyone else's surprise, Bakugou quickly lets go of Midoriya and steps
away from him, head in his hands.
"What did I fucking say? Do you want to die?" He lifts his hands up in an
aborted strangling motion before turning away from him to go take a seat.
Kirishima's a little surprised at how much Bakugou seemed to be struggling to
maintain control. His hands were popping with tiny explosions that sounded more
like bubble wrap than anything, as if Bakugou was physically fighting his quirk
down. He sure looked like it.
"You alright, bro?" Kirishima asked in a whisper. They had a few minutes until
Aizawa arrived, he could at least hope to ease Bakugou enough to last until
they had more time to speak.
Bakugou's nails raked across his desk, peeling at the wood beneath his fingers,
he looked back at Kirishima almost dully, leaning in closer than absolutely
necessary and wow did it suddenly get very hot or was it just him?
"Come with me to the locker rooms later."
Kirishima swallowed and nodded, fingers tapping nervously on his own thigh.
"Yeah, anything for you bro. As a bro. Of course." Was he breathing? He
couldn't tell with how close Bakugou was.
But just like that Bakugou sat back straight and Aizawa began the class.
When had he gotten there? Around the time Kirishima lost all sense of self?
Gods....
***** Chapter 3 *****
Chapter Summary
     Bakugou snorts, "Thought you said you mate for life? I was thinking
     we're life mates."
Chapter Notes
     Smut. Dirty smut. Just all smut.
See the end of the chapter for more notes
After class, Kirishima found himself in the locker rooms, glancing around
nervously. He could sense Bakugou wasn't there yet, unable to catch a whiff of
the boy's scent of chemicals and smoke. Which really shouldn't be an attractive
scent and yet Kirishima found himself drooling over it. He had it so bad. He
needed to control himself, maybe this wasn't what he thought it was at all and
Bakugou just wanted to talk.
In the lockers.
Alone.
When almost everyone had already left.
Okay he really didn't have a heterosexual way to explain it but he's sure it
exists.
Minutes later, just as he convinced his libido to settle down, Bakugou walks in
looking like he'd just been punched in the gut.
The boy's hand was holding his abdomen, and there was something off about his
scent. Naturally, Kirishima's first response was to worry, standing up to take
Bakugou's hand and hopefully help him sit down but no. As soon as his hand
comes in contact with Bakugou's skin, the boy rounds on him and suddenly he's
pinned to a locker with something warm and soft against his mouth.
Like with everything, it takes Kirishima a whole minute to realize it's
Bakugou's lips he's feeling, rough with their movement's but so soft it makes
him melt into it, pushing back against the movements with equal amount of
vigor.
When Bakugou pulls away Kirishima's chest tightens at the sight of tiny
pinpricks on his lips, from his own teeth. Just the idea of marking Bakugou up
with his teeth made him want to buck up and grind against him which is sad as
hell because all they've done is kiss for fuck's sake. Bakugou, however, had no
issue fitting himself over Kirishima's thigh and grinding down against him and
wow Kirishima is going to die a happy man.
He still has no idea what's going on.
"Katsuki, what-" he paused, feeling the boy on his thigh moan loudly and lean
in close, still grinding down solidly onto his thigh.
"I'm in heat, moron." He says, voice laced with a tiny growl. "Your fault."
 
Kirishima reels, "What do you mean?" He asked, heart threatening to thud
straight out of his chest. His fault. How would Bakugou going through his
mating cycle be his fault?
"I've never had a fucking heat before." Bakugou says, as if that explains
absolutely anything. "Wasn't supposed to have it until later but hanging out
with a potential mate speeded it up."
And just like that, Kirishima remembers he had forgotten about his rut and
showed up to class the first day of it and Bakugou had acted a bit strange
during it. He was used to people throwing themselves at him, and even triggered
a few people's heats by mistake that day, but Bakugou looked confused and lost.
It must have been his body telling him he should spend that heat and rut with
Kirishima.
But Kirishima can't let this happen, not when he respects Bakugou so much and
knows that heats can drive people to do things they'd never do otherwise.
"Katsuki, we can't-" he tried, instead all he got was a growl in a reply and
Bakugou stepped back to start stripping. He tried again, "Really, we can't,
you're not thinking straight and I-" 'Don't want to hurt you' was left unsaid.
"Shut up." The blonde growled, sitting back on one of the benches to wriggle
out of his pants and underwear. "I'm thinking fine. It's only the second day of
the heat, it just hurts like a bitch and it's your fault-" he snapped his
fingers and pointed at the floor, between his own knees, "-so get on the ground
and fix it."
Kirishima found himself on his knees before he knew it, much like when Bakugou
had first shifted in front of him. He was on his knees, moving forward to the
mess of blonde curls between the boy's legs. Not really a mess though,
considering they were well trimmed and groomed, as if Bakugou had prepared for
this.
He really did want him.
Kirishima gulped and glanced up at Bakugou. He was only a little ways away from
the boy's dripping heat, and the scent was making his mind cloudy with the need
to push his nose into the pale curls and lap up the juices he was dripping
everywhere.
But he wouldn't, not without explicit permission.
"What are you waiting for, shitty hair?" A pale brow raises at him and
Kirishima has to gulp at the confidence this boy has. He can't smell anyone
else on him, so if he had slept with anyone before, it was long enough ago that
the scent of sex had been completely cleansed from him. Kirishima doesn't know
if this sureness comes from experience or its just the type of person Bakugou
is. "If you don't plan on eating me out-" But Kirishima doesn't let him finish.
He decides to take it slow, nipping at the skin of Bakugou's inner thigh, sharp
teeth leaving little pinpricks along the pale skin. He's about to apologize for
it, but the look on Bakugou's face tells him it wasn't a mistake. Kirishima
nips his way along the other's thigh, groaning as the scent of heat and need
grows thicker. Obviously, he loves this, and Kirishima pats himself in the back
for doing so well despite his limited knowledge on all things sexual.
He gave Kaminari a hand job once but that was about it. Not like that
experience could be applied to this, which made him feel a little bit useless.
But Bakugou wanted him, and he wanted Bakugou, so he trusted the other would
tell him if he did something wrong.
"Stop thinking so much." Bakugou breathed with a shudder, tangling clawed
fingers in Kirishima's hair to tug gently. "You'll hurt yourself." But it held
no heat. It was almost...fond, and Kirishima melted into the touch because of
it.
"Sorry I just- never really used my mouth on anyone before?"
Bakugou hums and slides away from Kirishima until they're both on their knees,
facing each other. The blonde cups Kirishima's cheeks, leaning in close, "Never
had anyone touch me at all. Stop freaking out, mount me, mutt."
Kirishima can't help it, he outright moans as he lays on his back and pulls
Bakugou over him. The surprised look on the blonde's face only lasts a moment
before he's sitting back a bit to grind his wet heat against the bulge in
Kirishima's pants. That must not be the most comfortable, but Bakugou moans and
groans like it's the best thing he's ever felt and Kirishima loves to watch him
more than anything.
"Eijirou, you're wearing too much." He murmured, making no move to actually get
off so it involves a lot of awkward wriggling until he's down to his underwear
and Bakugou's back to grinding against him and God, he's not a strong man, he
already feels ready to knot.
Kirishima releases a shuddering breath and looks Bakugou in the eye as he
gently shifts them until he's on top, positioned between the blonde's legs
before he wriggles out of his underwear, presenting his cock to him, stroking
it torturously slow, "Should I stretch you?" He asked quietly, leaning closer
to lick and nip at his neck.
Bakugou hums softly and hooks his ankles behind Kirishima's back. "I swear to
fuck, if you're not eight inches deep in my cunt in the next five seconds I'm
letting Tetsutetsu fuck me."
Kirishima shook his head, moving a hand between them to rub around Bakugou's
clit with tight little circles, taking it as a victory when the other lets out
a low whine, hips twitching up into his touch. "Wouldn't be very manly of me if
I didn't treat you good for your first time, now would it?"
The tiger shifter bit his lip, hips lifting with the gentle rubs, "Thought
you'd do me like a dog." Bakugou says, distracted. But he looks almost ashamed,
almost. His face isn't made for the expression, but Kirishima sees it in his
eyes.
"Some wolves mate for life, Katsuki." Kirishima breathed into his ear, rumbling
happily when he slides a finger into Bakugou and he jolts up into the touch.
"I'm one of them. I'm going to fuck you senseless just like you need, sate your
heat and ruin you, but I want you to feel so good. I want to wreck you."
Kirishima revels in the full body shudder that goes through Bakugou, and he
doesn't mind being pulled into a rough kiss either. He uses it to distract the
blonde as he slipped in a second finger, playing with the third at their side.
He doesn't slide it in until Bakugou is purring against his mouth for more.
Fingers gently scissoring and thrusting to get him ready for something more. He
would worry about hurting him if it wasn't for how pliant he was, demanding
more and moving against Kirishima's hand.
Kirishima pulled back when he couldn't take anymore, looking down at his red
faced....friend? More than that maybe. He'd ask once the heat was sated.
"Ready?"
Bakugou groaned, "Get in me, god."
Kirishima complies, positioning the head of his cock and slowly sliding into
Bakugou's tight heat. He finds the juncture between his shoulder and neck,
moving to lave the area where he planned to sink his teeth into with loving
attention. Once he was buried to the beginnings of his knot, Kirishima breathed
out heavily against Bakugou's skin.
"Fuck you feel so good." He shuddered as he felt him squeeze purposefully
around him.
"Yeah? Wanna tell me all about it or are you going to fuck me to show me?"
Kirishima shuddered again before he began to move, hips pushing and pulling
against that tight heat, hand going down to rub tight, slow circles around
Bakugou's clit with each thrust. The way the boy moaned under him, moved so
eagerly against him, demanding "More" and "Deeper". Kirishima feared he would
knot him, but Bakugou seemed hell bent on being knotted, which was odd because
felines did not knot and he was not built for it, most would avoid it.
But Bakugou was not most and he was quick to push Kirishima onto his back to
climb over him and sink down to the half inflated knot, moaning loudly. "Fuck
yes." He hissed, hips bouncing on the redhead and good god Kirishima couldn't
breathe. He looked like a dream, blonde hair like a halo and red eyes shining
with lust, strong legs flexing with each movement until the knot was nearly
inflated all the way and he could do nothing but grind down against him. "Fuck,
Eijirou, breed me already." And just like that, he was spilling into Bakugou,
hot and heavy and he moaned throughout it all, moaning louder when one of the
shots of his cum seems to push Bakugou over the edge and he tightens unbearably
around his knot.
Bakugou falls forward onto Kirishima's chest, purring absently and rubbing his
scent into his skin. It's quite the while before Kirishima finds it in himself
to speak, "Are we... bros or more?"
Bakugou snorts, "Thought you said you mate for life? I was thinking we're life
mates."
Kirishima swallowed thickly and smiled wide. "Yeah okay."
