maybe you like that katsuki’s mean. maybe you just have a thing for blondes, whereas izuku has tufts of curly dark hair. regardless, he sees it all. izuku has watched you fumble and fawn over bakugou katsuki for as long as he can remember. quite frankly, he’s tired of remembering—of seeing. 

he should have expected that you’d invite katsuki to join you both at your house after you and izuku ran into him after dinner. you both go out quite frequently, always as friends, never anything more. but izuku wants more. no, he needs it. so it reasonably pisses him off when you give katsuki that wide-eyed look and invite him with you both. it reasonably ticks something off inside of him when katsuki turns you down and you sigh dreamily... like an idiot.

izuku really doesn’t think before he does it. he doesn’t really consider what he’s doing. 

he grabs your wrist and pushes you against the wall of the alley you’re in. izuku drags you sideways and pins you, chest heaving. 

“i could be a better boyfriend than him.” he says, tilting his head down to look at you. izuku uses his size, the muscles he’s accumulated since high school, as a trump card. proof that he can be just as big and bad if that’s what you like. 

“...what?” you gape. there’s the look. wide-eyed, glassy, so fucking dumb. god, izuku’s knees are weak. 

“what’s so good about him?” he asks, staring down at you. “he’s big? mean? I can do those things too.” 

“w-what are you talk-” you’re staring at him, shocked. izuku can read it on your face. the way your preconceived notions of him are melting away. he can feel how tight his grip on your wrist is. what’s better is the way you don’t squirm, the way you’re leaning into it. “izu... i have no-”

“you’re dumb now? thought you only saved that for katsuki.” izuku snaps, spitting the words at you. it’s too much. he’s too jealous. look at me. look at me. 

and you are. you’re staring really, maybe drooling. izuku can see the way the wheels in your head are grinding to a halt, he can feel the way your pulse picks up under the heavy thumb on your wrist. 

you mumble something. 

“what’s that?” he asks, teasing mostly. 

“what are you trying to do right now?” you don’t meet his eyes. instead, yours stay glued to where his feet encroach on your personal space. 

“isn’t that obvious?” he tilts your chin up so you’re looking at him. “i can do shit he’d never do. all you have to do is ask.” 

your breath catches in your throat. the swear is so unexpected, so out of character from someone you thought was gentle. izuku is salivating now. you’re giving him the look he’s wanted for so long, begging for it. fucking finally. 

“ask,” izuku says your name. “ask me for it, _____, or i’ll stop.” 

“.... me...” 

“louder.” 

“fuck me, izuku.” 

he really doesn’t need to hear anymore. in fact, his cock has been throbbing in his pants since he first pinned you. izuku’s so jealous. he’s a jealous being, so he presses his lips to yours hungrily. they’re so greedy and full, dipping his tongue into your mouth and swallowing the moan you give him. 

izuku drags you back to his flat, your hand firmly in his. you watch him the whole way, glassy-eyed. then he fucks you stupid, fills you with the heavy press of his cock. 

you’re so fucking tight, so sweet as you moan his name. his. izuku. you’re chanting it like a mantra as he fills you up, as he plugs you with the swell of him. 

izuku holds his hand to your forehead in missionary. he likes the inimacy of it, likes that he can feel your nails down his back, watch the way your face contorts into something indescribably erotic. you cum once, then twice, and a third time on his tongue as he eats himself out of you. 

and he’s mean to you, just like you like, aggressive. izuku cages you in and swallows you whole because if he doesn’t, his jealousy will do the same to him. so he treats you how you think katsuki would treat you, but he does it better. izuku knows he does. because he is better. izuku could be a better boyfriend. he’ll prove it now by breeding your tight cunt and then again the next time you see katsuki.
