stepbrother megumi ! tags: nsfw stepcest
stepbrother megumi, who had just moved into your house along with his dad, your stepdad, toji. as soon as you guys were introduced to each other you immediately folded. megumi studied you with a disapproving expression, shaking his head with a huff and already throwing his bags into the room that you’ll both be sharing. he seemed pissed, as if he hated you already. but he only brushed past you to the room so no one could see the boner he’s forming. he’s embarrassed, one look at you and he’s hard?? seriously!?
you knew this was wrong. your stepbrother?? really?! you tried to suppress these feelings, pushing them all the way down. but you couldn’t quite help it since you share a room anyway, and he was quite hot…
every night after his shower he’d walk into the room with his towel hung dangerously low on his hips. droplets of water glistening on his sculpted abs and prominent v-line. you gulped nervously as your eyes trail down his body. his eyes narrow at you suspiciously. “what’re you looking at?” he asks, voice slightly annoyed like always. “fucking freak.” he sighs to himself. but he knows exactly what he’s doing. he sees the way you press your thighs together and how your breathing is shaky.
you’d crash onto your bed after a long day, lying flat on your stomach and bending one knee up to your stomach, amplifying the plump of your ass. you’re wearing those tight pajama shorts. he stares at your ass from across the room in his own bed, watching the rise and fall of your back, watching the way your ass slightly jiggles with every small movement.
he gets up abruptly and walks out to go to the bathroom, slamming the door shut with a little extra force then usual.
in the bathroom he fucks his fist, biting hard on his free hand to muffle the groans that desperately threaten to escape; indifferent as he acts, he is just as down bad for you then you are for him.
but little did he know… you’d do the exact same thing. when he’d drift off to sleep in the middle of the night, you’d creep off to the bathroom and rub your clit in frantic circles, dipping your middle finger in and out of your needy hole. whining desperately into your hands or the nearest towel. Your fingers couldn’t reach all the right spots, leaving you a throbbing, leaking mess.
one night, it’s 2am. you’ve just been through the same dilemma of sexual frustration. not being able to feel megumis slender and veiny fingers fuck you. after you came, you washed your hands and opened the door to see a tall, muscular figure leaning against the door frame.
you craned your neck, it was megumi. his gaze upholding that constantly pissed off look, however… he had something else in his eyes. Lust. His pupils were blown wide, his cheeks were flushed a tinge of pink and he was already breathing heavier than usual. you were mortified. you’ve been in the bathroom for atleast 30 minutes trying to make yourself cum, and it wasn’t even a good orgasm either!
“how… how long have you been waiting out here for?” you asked slowly, cautiously, like you didn’t want to believe he heard you. “since you first went inside.” he answers bluntly. your eyes widened and a mortified blush crawls up your neck. “tell me, [name]…” he leans down, his nose just inches from yours, “do you want me?” his voice drops to a low whisper. you squirmed slightly, already shifting your thighs to press together. “fuck…” you sighed, “yeah.” you admitted bluntly, knowing there’s no going back.
suddenly he grabs your wrist roughly and practically drags you back to the shared bedroom. throwing you on your bed, and kissing you with a lustful intensity. he tugged your shorts down and you shimmied them past your ankles.
he stared at your soaking panties. “shit…” he breathes. “you’re this wet for your stepbrother?” he runs his thumb up from your clothed hole up to your clit, running small circles. your hips bucked almost immediately. you nod stupidly. he actually smiles, not necessarily a happy one— a smile that tells you he’s not holding back. “you’re such a slut. all desperate and needy for her stepbrother to fuck her. is that right?” his voice a low growl.
he pulls your panties down in one swift motion, staring at your glistening folds before immediately pulling his cock out of his sweats, not even bothering to wear boxers. he was just as desperate as you, he was listening to you touch yourself outside the bathroom door as he was aggressively palming himself. there was already a damp spot in the crotch of his pants but the room was dimly lit and you were too needy to give a fuck about anything besides him stuffing you full.
you were both leaking so much arousal, there was no need for foreplay. the real foreplay was existing near each other for weeks and not doing anything about the growing desire to feel each other.
megumis cock was long but slim, circumcised with a cute mushroom tip that was a light cool brown. his dick was decorated with veins and was blushing a light colour of pink from the base. he was hard, super hard. you could see how it twitched and throbbed as the air hit his sensitive dick.
he rubbed his cock against your folds, leaning down to press sloppy kisses on your neck. “this is wrong..” he murmurs, voice cracking slightly. his tip catches on your clit and both of you gasp in pleasure. “i- i know…” you panted. “if they come in, we’re so fucked..” you whispered, a whiny edge to your voice from just wanting him inside already. “it doesn’t matter— just… we’ll just think about this later.” he shook his head trying not to think about either of your parents coming in. he tip nudges your hole, his head already burrowing into your shoulder.
he presses deeper, and deeper. your breathy moans filled the room as his pretty dick was starting to fill you up inch by inch. finally, his tip nudged the one spot inside you that you could never reach on your own. you accidentally let out a loud whimper. he freezes and glares at you. “shut up.” he hisses. though, as much as he acted annoyed, you felt his cock twitch inside you. he starts to move but you’re struggling to stay quiet. he aligns his middle and ring finger with your mouth. “open.” he orders gruffly. you open your mouth obediently and he glides his fingers into your mouth. muffling the sounds that are spilling from your pretty lips.
god— he wishes he could hear your moans, he wishes he could see how loud you can get, he wishes he could fuck you on the couch, over the kitchen counter, in the shower. but for now, it’s going to have to be in your dimly lit shared bedroom trying to be as quiet as possible as his cock plunges immensely in and out of your perfect pussy. the room was filled with the scent of sex and the soft plaps against each others skin
he was groaning against your neck, rutting into you, trying to go as fast as he possibly could without the sound of his balls slapping your ass getting louder as well. he could feel your warm walls squeeze him so tight, making his eyes roll all the away back. you are so pretty, you smell so good, AND you feel so good. he just couldn’t do it anymore!
his thrusts became increasingly desperate, fucking into you faster and faster. megumis’ low growls and groans turning into breathy whimpers and small moans. your muffled moans increased in pitch, cracking as you were approaching your high. your hips bucked up uncontrollably, you were drooling around megumis fingers and your nipples were rubbing against the fabric of your tank top.
the stimulation was way too much, you moaned loudly, a spark of white flash through your vision as the best orgasm of your life hits you like a truck. your walls clench and spasm violently, your legs are shaking, and you’re panting like you’ve ran several laps. that undoes megumi immediately, his hips stutter before he cums inside you, kissing your neck trying to distract his mouth so he doesn’t make any loud noises. his arms were struggling to even hold him up, he collapsed on top of you. “fuck.” he spoke after a while, you opened your eyes, the post orgasm making you a lightly sleepy. “what?” you asked, voice a little hoarse. “i forgot to wear a fucking condom.” your eyes widened “shit.” you huffed an annoyed sigh. “its fine, i shouldn’t be ovulating anyway.” trying to lighten the subject. “you better not be.” he retorts, nuzzling into your neck.
“so uh… i should— probably clean you up, huh?” he speaks awkwardly, post nut clarity hitting him and making him realise he just fucked his STEPsister. “mmm.. i guess?” your tone just as awkward as you came to the realisation. he grabs a handtowel from the bathroom and dampens it a little, coming back into the bedroom and cleaning the mess on your thighs and wiping himself off too.
anywho— it’s safe to say that you slept really really good that night.
the next morning.. “you’re happy today, you got plans or something?” your mom asks you during breakfast. “yeah.. plans.” you replied, eyes drifting to megumi who was already looking at you with that knowing gleam in his eyes. you both looked away. megumi awkwardly clearing his throat and you continuing the conversation with your mom just as worse.
toji watches this exchange with a conspiratorial look on his face. his lips played his usual lazy, scarred smirk. but the way he leaned back in the chair and analysed you in a way that made you shift in your seat made you think that… he might be catching on.
or maybe… just maybe. he’s already caught on.
