note: hi!! my first nsfw post for mha. i’ve had this idea stuck in my head for months… hope y’all like ^ - ^ yes, this is inspired by romeo santos’ “eres mia” .
you should’ve known something was amiss. everything was going too well. the engagement, and the planning of the event, down to both the bachelor and bachelorette parties. even the rehearsal dinner had gone well. less than twenty-four hours remain before you tie the knot with tenya. tenya, who is the kindest man you’ve ever met. tenya, who, somehow, prioritizes you while keeping on top of his hero work. not at all like your last ex. you shake your head, forcing thoughts of him out of your mind as you change into your sleeping wear in your room. today had been the rehearsal dinner, and it had gone as perfectly as you want.
a slight breeze brings a shiver to your body. a breeze, that shouldn’t have existed, not when you know when you left your room earlier today, your windows had been closed. walking towards your windows, your heart falls to your stomach as you notice the open window. before you can retrace your actions from the day, a hand covers your mouth. your scream is muffled as you try to fight against the intruder.
“shh, baby, it’s me, it’s me,” the intruder’s voice is both breathy and raspy, with an underlying amused tone. his body is pressed behind yours, his free arm wrapped around your waist. you hate how after months, it’s still so familiar. “i can’t believe i leave for the states only for you to get engaged to the iida. iida. really? he’s so boring, baby.”
he continues speaking as he starts playing pressing light kisses to your exposed shoulders, “he’s so cold too… doesn’t deserve you.”
he finally uncovers your mouth and you immediately speak with venom on your tongue, “he’s a much better man than you are, sero.”
“sero, huh? no longer “hanta”?” he chuckles as he moves onto your neck, “kirishima was telling me how iida’s a jealous man. did you know he banned me from the venue? he must think i’ll steal his girl…” he bites down on your shoulder, drawing a gasp from you. you bite back a whine as you feel him smirk against your lips. “i guess he was right, huh?”
“why are you in my room?” you whisper as he switches to remove your clothes. he throws you onto your bed, and in the back of your mind, you know this is wrong. you’re engaged to iida. not sero. “we broke up.”
“did we?” he mutters under his breath as he starts unbuckling his belt. he laughs as he sees you hungrily eye him, “for someone who is getting married tomorrow, you sure are acting sluttily for a man who isn’t your fiance.”
he must have used some kind of quirk on you because why can’t you move? he must’ve bewitched you. you’d never cheat. never. but… you can’t help it as you moan as he presses his lips to your breasts. he hungrily laps at your nipples, drawing a moan out from you. he’s still in his hero uniform as he presses his boner against you.
“have you fucked him?” sero asks as he unlatches from your nipples. his smile falls when you nod. your surroundings spin as he flips you over. “guess i’ll have to claim you again.”
“s-sero-,” you begin to protest but he pushes your face into the sheets. you whimper as he presses his hardon against your ass, and you can’t help but squirm a bit. it seems to set him off and you can only yelp against your sheets as he forcedly enters you. there’s already some wetness dripping down your things and your face warms with embarrassment.
his grip is tight on your hips as he begins fucking you without mercy. you move your hips back, meeting him as he thrusts inside you. whimpers and groans along with the sound of skin slapping skin resound through the room.
“such a slut,” sero says as he increases his pace. one of his hands reaches out to your shoulder, lifting you up slightly. you moan freely, no longer caring as he continues remolding your pussy into the shape of his dick again. “fuck, i missed this pussy so much. dropped an entire mission to fucking see you again. shit-so tight-, you sure you let him hit?”
“y-you have the biggest ego,” you manage to say as he leans down to suck a hickey into your shoulder, ignoring your whines of protest.
“do i?” his voice is cocky as he leans back up. he grabs one of your legs and lifts them enough for him to get deeper inside you. “is it egotistical to just want you back?”
“i’m not yours anymore,” you say, but it’s weak. you know he doesn’t buy it either as he laughs and the sound only makes your stomach churn.
“please, playing stupid doesn’t fit you,” he hisses as he thrusts harder, “you’re mine and you know it,” a particularly hard thrust has you seeing stars. it only boosts his ego, “there it is. did he ever find that spot?”
any reservations you had are gone now and you shake your head. you can barely recognize your voice as you sob, “no, he never did.”
“thought so. did he ever even make you cum?” he doesn’t wait for an answer as he continues fucking you.
“‘m gonna cum,” you whisper as you start to move a hand down towards your clit. he slaps it away before you can. “‘m gonna cum’,” he mocks you before turning you on your back. “no, you’re not. you’re gonna cum on my dick alone.’
he pushes his cock into you again, cursing as he does. you wrap your legs around his waist and you can’t find yourself caring about the smug look he gives you as you do. he leans forward to kiss your tears away, “tomorrow, what do you think will happen if i sneak into the reception? if i tell your husband that the woman he loves is only a loan because you’re still mine?”
“y-you wouldn’t dare!” you hiccup as you wrap your arms around his neck. his thrusts only get quicker and harder as he laughs against your neck.
“you know it’s true,” he says as he sucks a hickey into your neck, “you know you still love me,” he thrusts again at the end of the sentence, and you throw your head back in pleasure. “c’mon baby, i know you’re close. such a slut, letting yourself get fucked by someone who isn’t your fiance.”
“‘m…not yours,” you lie. both of you know it’s a lie as his moans become airy and shaky. he calls you out on it, “liar. this pussy,” he reaches down to slap your clit, making you cry out, “is mine,” his hand moves down to your ass and he slaps it, “so is this ass,” his lips move down to your chest, pressing a kiss, “and so is your heart. it’s never been iida’s. never.”
the pleasure from his dick constantly hitting your spot with his words make you cum, immediately clenching down on him. he swears and you recognize the familiar tremble in his body as he cums inside of you. it only makes both of you moan louder as he marks you again as his. he collapses on top of you, limp as you close your eyes tiredly. you don’t have the energy to move him away from you as he grabs your chin. “hey,” he says quietly.
“what?” you ask tearfully as you gain clairty post-orgasm.
“i was serious earlier. i want you back,” he says and you shake your head.
“don’t say that.”
“don’t marry him. i’ll prove to you i’ve changed,” his voice is gentle and warm, but you know if you continue listening you’ll just fall for empty promises again. “don’t get married tomorrow. stand him up. i’m sure uraraka or someone else can mend his heart back together. maybe aoyama.”
“no, hanta. get out.”
“baby, please-”
“get the fuck out!” you yell as you manage to push him off, avoiding eye contact with him as you cover yourself up with your sheets. “you abandoned me and i didn’t even get an explanation. i don’t care what you have to say.”
he doesn’t respond as he gets out of your bed, silently redressing. once he’s done, he walks over to your window, beginning to leave. he pauses when he hears you sniffle.
“i’ll be waiting back at our old place,” is all he says as he slips out your window, not sparing you another glance.
he knew from the second you said his first name again that he’d have you back in no time.
