woke up thinking of izuku and ochako dating and everyone calls them the cutest couple. they're the sweetest, most wholesome thing ever. they're ua's "couple goals"

and then izuku asks katsuki, "would you fuck me?"

preface: ilu uraraka im sorry i like making u suffer bc ur boyfriends gay is it self projection to my first boyfriend bc i left him for a girl back when i thought i was a lesbian? who knows! but its sure as hell fun to cuck her!

cw: trans katsuki + afab language, cheating

the girls are downstairs having a movie night or some shit. theyve got facemasks and nail polishes out, 20 different horror movies that izuku lowkey kinda really wants to watch too and maybe even wear a facemask but the girls kick him out.

"its girls night!" mina screeches in his ear. "you're a guy! not allowed!"

izuku leans his weight back on the hands that struggle to push him up the stairs and says, "that's kind of stupid."

"stop making yourself heavier!"

"stop making it so fun!"

in comes ochako to

press a pretty little finger to his shoulder and make him float. he whoops as momo tells him not to stain the ceiling w his feet.

"we're not a couple for tonight!" she tells him. "so go be with your boys and dont come downstairs! tv is ours tonight!"

izuku laughs. "alright,

alright. can i have one last kiss before you stop being a girlfriend tonight?"

"/for/ tonight," she pulls him down by the shirt, pressing a sweet kiss to his lips. "now leave."

and izuku does.

and he also ends up on katsuki's door.

its 7pm, so he assumes hes awake, but even if hes not, theyve developed enough of a maybe friendship these past few years in ua that izuku feels pretty confident he wont get his face blown off if he chills out in kacchan's room at night.

it's not like they havent before, anyway.

izuku spent most of his 2nd year in katsuki's dorm instead of his & when he and ochako got together in 3rd, izuku divided his time between the both of them.

there is no izuku without katsuki-- no deku without kacchan. so at some point ochako had to stop side eyeing them, right?

anyway, izuku ends up at his door, knocking three times before impatience settles in and hes groaning against the door barely five seconds after hes knocked.

he grins when he hears the man inside say, "shut up-- shut the fuck up, im coming!"

when the knob turns, he pulls the door open the rest of the way, making katsuki stumble forward. his grin widens as he says hello and walks in without permission.

"damn, no 'pardon the intrusion' or some shit?" katsuki asks him, but makes no effort to stop him from climbing up

and settling on the corner of his mattress.

"nope!" he throws back, pulling the laptop on his bed closer. "let's watch a movie! the girls are watching the autopsy downstairs and had some-- were you watching porn?"

katsuki's face turns beet red. "the fucks it to you?"

"i mean, im looking at your incognito like you didnt even have time to exit out of it." izuku says, and then barks out a laugh when he reads 'twink begs dom for creampie'

"jesus kacchan, what is this!"

"kinkier than your sex life, judging by your vanilla ass reaction"

izuku sputters. "wh-- no! it's not vanilla!"

katsuki crawls into his bed and jerks his laptop away from him to exit the tabs. "ive seen your porn history too, dumbass. if a creampie makes you stutter then shes turned you into a missionary on saturdays couple"

"its not--" izuku thinks back on how sex with ochako is always a three step system of kissing, oral, and penetration. nothing more, nothing less. she mightve jerked him off once, but if izuku remembers correctly, it's because they only had 20 minutes. but he cant tell kacchan hes

right, so he frowns and repeats, "its not!" and tries not to cringe at his weak argument when katsuki throws him a look.

he shuts up after that, pouting slightly as he watches the other look up horror movies on hulu. hes surprised he wasnt kicked out, even more that katsuki

didnt question nor deny his request to watch the same scary movies the girls were watching downstairs. he couldve told him t ok watch them himself, but he thinks it's the fact he was caught off guard probably jerking off that made him not kick him out. maybe he felt incriminated.

either way, they make it an hour into the shining before izukus huffing out, "it's not vanilla!"

he doesnt expect katsuki to laugh, but the sound is welcome anyway. "if it wasnt, you wouldnt be so pressed about it!"

"its not!"

"oh my--" katsuki rolls his eyes. "okay,

whatd you do yesterday?"

izuku blinks. "yesterday was thursday."

"yeah. whatd you do on thursday?"

izuku blinks two more times. "um."

"you didnt have sex, did you?"

"no.."

katsuki laughs again.

"it's a thursday though!" izuku argues, "who the hell has sex after heroics! we're sweaty and gross and--"

"that's the point!" katsuki throws back. "do you have any idea how many times ei and sparky fuck after sparring? cmon, deku, you havent watched

round face do a cool move and thought 'holy shit, she looks hot'?"

"of course i have!"

"and you havent had sex after that thought?"

"ive tr-- no!"

katsuki blinks at him. "wait. so you've tried?"

"we're not vanilla!"

"dont change the subject!" katsuki snaps. "you've seen her after practice and wanted to have sex and she shuts it down every time?"

the way red eyes stare at izuku makes him squirm, makes him wonder if its him that's doing something wrong. "maybe...

i mean, ive only tried twice so maybe i just have bad timi--"

"deku, ive heard half of ua say they wanna fuck you after they see you fight."

they're quiet after that. katsuki holds his stare until izuku looks down, and then he sighs as he presses play again.

the movie nears its peak, the horror music playing in the background between the two boys that pay it zero attention.

finally, izuku breaks the silence and asks, "would you fuck me? after heroics?"

"yes."

the quick answer makes izuku's eyes snap to him.

"i mean, like. yeah,

I'd fuck my partner after heroics if i had one."

"you wouldnt be too tired?"

katsuki shakes his head. "i think id be more motivated. its hot-- to fuck someone after one of you won a fight. kinda feels like--"

"the winner taking the prize?" izuku finished. "not that shes a

prize."

katsuki nods. "yeah. no. shes not. right."

a beat passes between them, and then izuku pauses the movie and shifts to face katsuki. "okay. but like, let's pretend it's not her, right?"

katsuki thinks izuku shouldve known those words never bode well for a couple.

its logical. the half that starts with 'what if it wasnt my current partner?' will always end with 'my ex's.

katsuki makes no effort to stop him. in fact, he nods in encouragement.

"let's say it's not ochako," izuku continues. "let's say its-- fuck, shanta. or- or you! we fight all the time!"

katsuki nods again. "we do. we do fight all the time."

"if we sparred and i won--"

"the fuck makes you think youd win?"

"kacchan!" izuku stresses. "the point!"

the blonde rolls his eyes. he shuts his mouth afterwards, keeps his lips closed in case it spooks izuku's verbal fantasy of them sparring and fucking afterwards.

"if id win-- or. well. if /you/ win," he says, to make himself feel a little better about this. "then youd fuck me?"

"yes."

"no hesitation?"

"no." he shakes his head as he says it. "itd be like taking my prize."

"youd consider me your prize?"

katsuki stares at him. "you wouldnt consider me one if we fucked after you won?" he asks, an eyebrow quirked in disbelief.

"you and i have been competing over nothing our whole lives--"

"/you've/ been competing over nothing." izuku corrects. "i just want to be there by your side."

"you're by my side now."

"so then youd fuck me?"

"the hell you keep asking that for, shitty de--"

"kiss me."

katsuki jerks back, bracing his weight on his forearms. he opens his mouth to ask what the fuck izuku means, to mention he has a girlfriend. he knew the topic of conversation was stomping on thin ice, but this feels like hes already been submerged.

izuku presses his palm against his chest, and his eyebrows frown like they always do when hes about to cry. "my heart's beating so fast and I'm shaking and ive never--"

felt like this.

katsuki's eyes widen.

oh.

they hold eye contact for a while, and just as izuku's lips part to whisper "please", katsuki leans in.

his heart beats so hard he hears it in his ears, pounding away as his lips-- wait, the fuck? why the hell are izukus lips so soft?

he chases after them when he pulls away, eyes opening to catch the greenette centering himself. his eyes are still closed, and his lips are parted like he doesnt want to forget the shape they were when he kissed katsuki, even though he was the one to pull away.

he cant help but ask, "she ever make you feel like that with a kiss?" a little too low, too gravely for an innocent question. they're part that point of ignorance. they cant feign it was some spur in the moment shit. they cant spin a lie and pretend izuku didnt cheat,

not when hes opening his eyes to stare intently at katsuki, green almost brown, shaking his head no as he leans in again.

theres no going back. and katsuki doesnt want to. if hes honest, hes been waiting until they fall apart so he can pick izuku back up. hes not letting this go

their second kiss is a little more hurried, a little more desperate. it's like a new flame was lit inside izuku.

it's like a new quirk revealed itself to him, and katsuki smiles against his mouth at the thought because that's it, isnt it? it's always katsuki lighting him up.

so when he crawls into his lap, hands smoothing themselves up his chest-- god that chest, it's gotten so much bigger since their first year, fuck-- he feels his own chest warm up. he threads his fingers behind izuku's head, curls caught between them as he opens his mouth and lets

their tongues slide, and his chest feels like it's on fire. he feels like hes swallowing it all down, stomach flipping at the sight of flames, navel dipping at the heat.

"kacchan," izukus hands are everywhere, and hes not soft about it.
