you’d recognize that unruly head of pink hair anywhere. perpetually fastened underneath a ballcap like always.
you turn a little faster than you should, jostling the plastic solo cup you’ve been curled into for the past hour. sukuna looks right at home, backwards hat on like always, sweatpants slung low and easy on his hips now that you think about it, wasn’t this his frat house?
he waltzes into the kitchen and circles the island to lean next to you, hip against cold granite. his cologne must be doing something to the nerve endings in your brain, because all that comes out of you is a quiet, painfully deadpanned:
he laughs, nose crinkling in that sexy way you definitely haven’t thought about every day for the past 3 months. you’re barely given time to respond before a tattooed hand reaches forward and plucks the cup from your clammy hand, downing the last of whatever cheap liquor you were too nervous to finish anyway.
you watch, awestruck like a deer in headlights. taking in the way his throat bobs when he swallows. how he wipes the corner of his mouth with his thumb, sucking a stray drop of from the pad of his thumb.
“fuck, you drink fireball? didn’t think you’d be the type.” he jests.
was he flirting with you?
sukuna chucks the cup somewhere to the side. probably somewhere near a garbage can. not that you can tell with how many people are crowding the kitchen.
“so.” sukuna says, looking back at you expectantly, “we have senior seminar together, yeah?” he smiles, head tilting to the side like he’s trying to get a read on you.
right, the class he couldn’t care less about. you’ve seen him look up from his phone and engage with the topic, what, maybe twice? it’s a miracle he even recognizes you.
“i remember you, don’t worry.” you laugh, leaning back and forth on the balls of your feet as you desperately rack your brain for a way to keep the conversation going.
of course you remember him. you sit next to each other. you’ve scrolled marathons through his instagram page in the privacy of your room. hell, you’ve spent so much time thinking about him that you’d probably be able to pick his biceps out of a lineup. “remember” doesn’t begin to describe it.
sukuna speaks up again, mouth curling at the side like he’s got something up his sleeve. he gives you a quick once over, arms crossed over his chest casually.
“you look good tonight. enjoying yourself?” he’s not subtle in the slightest, red eyes scanning your figure, committing every inch of you to memory. the thought alone feels filthy. like tree sap settling in the pit of your stomach.
you must’ve unknowingly done something worthy of sainthood this semester. that’s the only explanation as to why the campus frat legend is eyeing you like he wants to eat you alive and lick his fingers clean after.
you don’t even care that he’s probably pulling out the same five tricks he’d use on any other girl. you’re falling faster than you ever have.
you make a mental note to thank shoko profusely for convincing you to socialize tonight. she’d given it to you straight like always, something about being tired of you complaining about your glaring lack of a roster. encouraging you to maybe go out and actually fuck a guy instead of settling for getting fingered by some loser like you always did.
senior year was supposed to be memorable after all.
“do you even know my name?” you mumble shyly, fiddling with the hem of your shirt.
sukuna pretends to rack his mind for an answer. tongue pressed against his cheek in a way that makes your breath catch.
your name rolls of his tongue beautifully, punctuated with that fangy smile you’ve daydreamed about. he says it like he’s recited it a million times. like the very existence of you on his tongue is second nature.
wow. ok. you might’ve misjudged his attention to detail.
sukuna must notice the surprised look on your face because he leans in a little closer. just enough for you to feel the heat radiating off his body.
“are you gonna answer my question?” he asks you.
right, if you were enjoying yourself. you try to think of something witty to say, painful aware of how intently he’s looking at you. the attention feels so sudden. he was never this forward in class, why come up to you now?
sukuna’s eyes never leave your face, watching, craving.
“honestly? yeah, i’m having a great time.” you settle for some simple honesty. somewhere in the background the incessant thump of a bluetooth speaker fades the more the scent of his cologne fills your lungs.
“what about you?” you ask.
sukuna pauses, eyes flitting over the crowd like he’s debating whether or not he can actually say what’s really on his mind.
his jaw flexes, fingers drumming against the counter to the beat of whatever song is playing.
he looks back over at you when he finally makes up his mind, gauging your reaction with a sly look in his eyes. thank god he can’t physically see the way your core flutters around nothing. you’re already too conscious of the sticky flush collecting in the gusset of your panties.
“i mean..." there's a playful tilt to his voice, his words steeped in mischief.
"usually i’d be upstairs by now having some fun.”
sukuna sighs, eyes glued to the swell of your lips.
“but, y’know, i get it. with finals week coming up. not a lot of fun to be had if no one else is looking for it.”
his voice trails off as soon as his eyes lock onto your lips. mumbling the last bits of the sentence like his mind is elsewhere. wanting.
something hangs heavy in the air between the two of you, something he hasn't said directly just yet.
fun. the implication of the word isn’t lost on you in the slightest. sukuna was a decent guy all around, maybe even an acquaintance now, but you’ve heard the way girls talk about him around campus.
lack of experience aside, you’d have to be an idiot to fool around with a guy like him. one that treats college like a fuckfest and sweet talks anything with a pulse. did you really want ryomen sukuna of all people to be your first?
maybe you are an idiot after all. because the speed those four words leave you is absolutely unparalleled.
in your defense, you can barely think straight as is. not with how close he is to you now, mouth curling up into the tiniest smile. and especially not with how satisfied he looks with himself.
“yeah?” sukuna’s pupils are two black voids, waiting for you to confirm your little unspoken agreement.
suddenly everything you’re feeling in your lower half makes sense, because the intrigue in his voice is something you’d literally pay money to hear again. you needed him bad.
“wanna find out?” you ask, more confident this time. technically not a bogus offer. you’ve done almost everything leading up to the deed. how hard could going all the way be?
sukuna’s room is a world of its own. tucked just upstairs and to the left of the beer can littered stairwell he’d made a beeline for as soon as you'd given him the green light. he weaves the both of you through the dwindling crowd, hand around your waist like you belong to him. in a way, you already do.
it's like the world around you ceases to exist as soon as his door locks and your back hits his bed. you're hyperaware and not aware of anything all at the same time. honed in on the way he toes his sneakers off and clambers onto the mattress atop you, hands running up the length of your body before diving to claim your lips.
you've made out before, sure, but never quite like this. never so passionately, in the way that makes your thighs clench and your core shake. sukuna licks into your mouth with desperation you never would have expected. like your tongue is his salvation.
“pretty girl, y’know that?” he mumbles into your mouth. "gonna fuck you good."
the compliment pulls the sweetest little whine out of you, and sukuna grins against your lips like he's won a prize.
touching you isn’t what turns him on most, you realize. it’s not the feeling of your arms wrapped around his neck, or the incessant press of your clothed centers. it’s the reactions you give him. those tiny huffs of breath against his mouth that let him know you need him. how you lean in close and pepper kisses down his throat just so he won’t see you blush. it’s all pure magic to him.
you're nervous in the best way, slipping your hands under the thin fabric of his wifebeater to feel up his abs. something about him just melts your brain. his scent, how warm he is, how he kneads your body like dough.
most importantly, this sex stuff was a cakewalk so far.
"off?" you plead, pushing his shirt up and over his shoulders like its somehow offended you, and sukuna laughs, hard and heavy.
"what, can't wait?" you he’s only asking to see you writhe, cocky little grin on his face and everything. you nod, and sukuna laughs, running his thumb over your bottom lip.
you must be too honed in on his lower half, because you don’t realize he’s taken off his hat to undress until he fastens it backwards right onto your head.
“hold that for me.” he says, shucking his shirt off and to the side with a grunt.
you didn’t expect this whole ordeal to feel so intimate. for him to lay you down against his pillows and kneel. wearing his hat while you watch him strip down to his boxers, the party still raging downstairs.
sukuna looks so much different like this. softened around the edges by the messy pink fringe that falls right above his eyes. you think you quite like the way the tattoos under his eyes crease when he looks back at you and smiles.
you wonder how many girls have seen him like this. if any of them appreciated the way the moonlight peeking through the shades illuminates the black lines on his body the way you do. or how pink his lips are after he’s been kissed.
something inside tugs at you when he reaches forward to take his hat back.
“keep it off.” you sit up, slipping it off your head to toss it onto his nightstand.
he pauses, like his brain is still trying to register what you've just told him.
“but the hat stays on when i fuck.” sukuna fake pouts. “that’s like my whole thing.”
“leave it.” you urge. "you look nice with your hair down."
sukuna’s face softens the slightest bit. he almost looks embarrassed. like the compliment isn’t something he gets told often.
“don't make me blush” he teases, hugging your middle to bring you back down to the pillows with him.
your own shirt is next to go, chucked over his tattooed shoulder to reveal the soft swell of your breasts.
“fuck, where’ve you been hiding all this?” sukuna breathes. awestruck like he hadn't been staring at them all night.
his attention is completely addictive. the more sukuna touches you, the more you start to understand the droves of girl you see hanging off his arm every weekend. groveling for his acknowledgment in any capacity.
you’d do a whole lot more than grovel if it meant he’d keep massaging you through your bra like he is now. you‘be never wanted anyone quite this bad like you do now. mind, body, and soul.
your bottom layers go next, lost to the abyss that is his floor. sukuna takes a moment to turn your panties over in his hand.
you half expect him to throw them on the ground as well, maybe stuff them under his pillow or something. except, sukuna does neither. instead, the garment joins his hat on the nightstand. situated amongst his things like they've always belonged there.
you'd let him keep them if he asked.
that’s when the gravity of it all really sets in. you’re naked as the day you were born, laid up underneath the hottest guy you’ve ever had the pleasure of viewing. and all he can do is look at you like you’re the most wonderful thing he’s ever seen.
sukuna whistles, low and slow, hand on your knee to part your legs.
“god, that’s a sight isn’t it. pretty down here too.” the bass in his voice practically makes your eyes flutter. that anxious feeling in your tummy slowly starts to dissipate as you spread yourself wider, morphing into something sappy nestled right at your entrance.
it’s almost humiliating feeling how wet you are, but sukuna doesn’t seem to mind at all, sauntering onto his stomach tongue-first like some sort of horny olympic diver.
his tongue hits you first, licking thick stripes from your hole to your clit. he parts you with a thumb on either side of your heat, not at all minding the way you pull at his locks.
sukuna was a lot of things. charming, outgoing, sometimes even vulgar. but one thing you’ve learned just in the last 10 minutes of lying atop his sheets is that he is anything but a selfish lover.
his fingers are a welcome intrusion. thicker than yours in a way that makes your head feel loose. the stretch only stings for a second, hotwiring the cogs in your lower stomach like a well oiled machine.
“fuck, you're tight. needy little thing.” he mumbles, pulling the digit out and bringing it to his mouth to suck your mess clean, then diving right back in.
it must kill him. hearing you, tasting you. wanting so badly to relieve himself but wanting to make you feel good even more.
he takes his time fingering you open, feeling up your slick walls until he finds that special little spot only the toys under your bed can reach.
you’re inconsolable, panting and groaning into the crook of your elbow while he rocks your entire world up, down, and sideways. you’ve never felt pleasure so blinding.
you go to say something, anything to let him know how fucking good he’s making you feel, but something else catches your eye instead.
the slightest movement of his hips, so quick you nearly miss it. then another, and another. his hips drive down, then back, pulling a shaky groan from the depths of his chest.
“are you humping the mattress?” you breathe.
a chuckle is all he gives you, nodding his head between your legs in a way that says “yeah, so what?” sukuna sucks your clit into his mouth for good measure, shoulders shaking at the near pornographic moan that escapes your lips.
"toji's room is right next door, you know. better keep it down." he laughs from between your legs.
right. the meathead you saw downstairs licking fireball off the floor on a dare. real classy guy.
you swat at him lightly when he comes up from your pussy, accepting the sticky kiss he presses to your lips.
he motions for you to sit up, and you do, following his lead. sukuna slinks in behind you, sitting up against his rickety headboard to shuck his boxers down with a huff.
you couldn’t have stopped yourself from reacting if you tried.
sukuna was thick. thicker than any toy under your bed or any of the half-chub losers you’ve fooled around with during the past four years here. long, flushed, and heavy. pre beading at his tip just aching to be licked off.
he shakes his head fondly at your lack of a filter, widening his legs so you can settle on your stomach between them. sukuna feeds you his cock with a loose grip at the base, throwing his head back with a groan as soon as your tongue meets his flesh.
you could very well get addicted to the taste of him. that salty tang that coats your taste buds and settles at the back of your throat.
five thick fingers sit at the base of your skull, gripping the back of your neck to guide you down as far as you can handle. it takes a couple tries, but you finally feel your nose rub up against the patch of pink hair at his base, earning a hearty groan from the man above you..
you’re not a pro at sucking dick by any means, but the sounds sukuna makes would have anyone thinking otherwise. long, gravelly moans. radiating right from within his chest and up to his ceiling.
"fuck, fuck hold on." he begs, letting his head fall forward with a shiver. you slowly ease his cock from your lips and look up at him expectantly.
sukuna squeezes the base of his dick with a huff. no doubt trying to starve off his orgasm. he looks up at you through his fringe with that same fangy smile you love.
“how do you want it?” he asks you, wiping the spit from the corner of your mouth.
right. the main course. full blown sex.
you suppose on your back would be best. comfortable, safe. you let him guide you back down onto the pillows and offer yourself up to him, feeling your stomach twist in on itself as he rolls a condom on and lines himself up with your entrance.
sukuna ruts his hips forward only slightly. not enough to breach but close enough for your fold to part around his tip.
you immediately lock up, joints stiff with adrenaline. the sensation is so foreign, thicker and hotter than anything you've ever felt.
“what?, don’t get shy on me now.” he drawls, tattoos straining against his lazy grin. “not after all that talk earlier.”
“waitwaitwait.” you hiss, pawing at his shoulder with a shaky hand. “oh my god—hold on.”
sukuna’s hips retreat, taking a bit of your anxiety with them. there’s a softness in his eyes, almost guilty in nature.
you say nothing, trying to piece together the 3 words you probably should've uttered a long time ago.
“want me to eat you out a little more?”
“no, sorry, it’s not that.” you clarify, cutting him off at the last syllable. the way it comes out makes you cringe.
the room suddenly feels a lot smaller than it did before. sukuna searches your face for an answer, silently pleading with the furrow between his brows.
"i've never done this beofre."
you prepare to watch the expression on his face melt into something nasty. to maybe hear something laced with pity leave his lips before he tells you to get dressed and get out, but it doesn’t come.
instead, sukuna’s expression softens, red eyes melting around the edges as he looks down at your shivering, naked form.
“yeah?” the way he says it is so quiet, so cautious. not at all like the outspoken boy you thought you knew.
you nod, fingers curling around his bicep uncertainly.
sukuna reaches to take that same hand, pressing a fleeting kiss to the inside of your wrist. his gentleness almost feels unbecoming. so out of character compared to the stories you’ve heard each semester. but not at all unlike the charismatic guy you’d come to know tonight.
maybe you didn’t really know the real sukuna after all.
“do you..? or— i could teach you. or we could stop. i can walk you home.” his tongue flits over your wrist, soothing the hammering pulse point there.
you ponder his offer for a moment, eyes transfixed on the way he mouths at your delicate skin.
“you don’t think it’s weird?” you mumble.
sukuna presses his tongue against his teeth, voice dropping the slightest bit like he really shouldn’t be saying what comes out of his mouth next.
“I think i’m kinda into that stuff.” he admits, chuckling like it’ll somehow ease the awkward air. “kinda… maybe guessed downstairs that you were kinda shy? i donno. made me wanna talk to you.”
your eyebrows nearly touch your hairline at his confession, embarrassment flooding you from head to toe.
“i mean, i figured the silent girl from class probably wouldn't have too many nights under her belt.” he jokes, charming as ever. you don’t take any offense to it.
sukuna must sense the thoughts flying through your mind because he stops, taking your face in both of his tattooed hands in a way that sets your chest on fire.
“it’s whatever you want, okay?.” and the little smile he gives you is so devastatingly reassuring, that you all but make up your mind right then and there.
“i wanna keep going.” you whisper, leaning forward in a brazen display of confidence to seal your lips to his.
sukuna must be taken aback by your forwardness, because he doesn’t melt into the kiss immediately. instead, his hands trail over your hips, getting a proper grip on your body before he’s pressing you into the mattress and licking into your mouth.
he almost tastes better this way, like grenadine and the remnants of a cigarette. the party rages on below you, drowning out the little whimpers that escape your lips every time sukuna kneads the sensitive swell of your breasts with his rough hands.
he lets you get used to the stretch this time, easing his hips back and forth in little strokes to get you used to the motion.
it doesn’t feel great at first, being fucked open at the center by something large enough to rival the width of your wrist. but soon enough, the discomfort fades into something different.
something filthy, nestled right in the deepest pit of your center. blooming out and upwards until your whole body feels like its on fire.
“oh my god.” you whimper, realizing you’ve taken him to the hilt. you're so full that your chest starts to feel tight. like there isn't possibly enough room inside of you to fit all the pleasure building in your core.
sukuna’s must adore the noises you're making for him, because his cock twitches right against that little spot from earlier.
“yeah? want me to move?” he purrs.
never in a million years did you think he’d be this intimate. this gentle, coaxing you open with his dick as softly as he can muster, and loving every bit of it.
“pleasepleaseplease oh god.” you moan, grasping onto his shoulders to prepare yourself for the onslaught of sensations that hit you when he speeds up.
you’re so wet you can’t even feel the friction of his heavy cock against your walls anymore. just the smooth, effortless glide of his length and the occasional, devastatingly good, bump of his tip against your g-spot.
you could die happy like this, legs spread to accommodate every inch of his sculpted body, watching the sweat collect in the ridges between his abs. listening to him pant praises against your lips in between heated kisses.
"could fuck you for the rest of my life." he growls.
and if that wasn’t enough, the finishing blow follows.
“i only come to class to see you, baby. only show up to see that pretty face.”
a broken whimper of his name is all you’re able to force out before you’re sent plummeting over the edge.
you cum with a stifled whimper, arms wrapped around his neck like he’ll up and float away if you let go. the pressure between your legs is insane, peaking and crashing down like an array of fireworks.
sukuna follows almost immediately, pulling out to shoot his load over your mound and lower tummy with a string of expletives and praise.
you silently thank the powers that be for whatever odd stroke of fate that brought you two together tonight.
“feeling good?” he flops on his side next to you, head propped up on his hand while he tenderly looks over your body.
“mmm, hoped you’d say that.” he laughs. still high on adrenaline.
the room suddenly feels a lot larger than it did before. a lot louder too without the sounds of your shared pleasure muffling the party below. you wonder what you're supposed to do now that you've... sufficiently had your fun. should you ask for a towel? should you just redress and deal with it all later?
sukuna opens his mouth like he wants to say something, then snaps back to attention.
"shit.. towel." he mumbles, slinking off the mattress to toe around the moat of your shared belongings on the ground.
"here." he tosses you the tank top he'd been wearing earlier, flopping back down on the mattress with you. you stand to dab the mess from your body and toss the garment in his hamper before pulling your undergarments back on.
sukuna lifts his head from the pillows, hand coming up to stroke over the back of your head.
"do you want me to leave?"
"do you want to leave?" he asks.
"then don't." he states plainly, already sorting through the mess on the floor to pull on his boxers. humming a tune under his breath like its the most routine thing in the world.
in a way, you guess it is. for him at least. you couldn't figure out what to do right now even if you tried.
"you said you noticed i was shy in class?" it comes out more like a statement than a question.
"noticed a lot of things about you." he whispers. you feel your stomach jump. half anticipation half need.
"why only come up to me today?"
sukuna sighs, like the topic itself is something that’s weighing heavy on his mind.
"didn't think you'd give me the time of day." he almost sounds shy to admit it. "thought i might as well when I saw you in the kitchen. didn't wanna graduate without giving it a shot."
something in your chest unravels softly at that. you feel at ease now, more confident in your bearings.
"can we do this more? get to know each other better?" you don’t even know where the question comes from, never mind how you garner the confidence to ask it.
you see his brows raise just the slightest bit, crimson eyes widening.
“or. sorry- i know you have…” your mind flits back to the image of him practically drowning in female attention. you probably sounded ridiculous right now.
you gesture vaguely in front of you, trying to phrase what you’re about to say as respectfully as possible. sukuna pulls you closer.
sukuna hums thoughtfully, like he’s already made his mind up.
"i'm sure they'd live without me.”
without him. like, in the complete absence of him. your mind finally registers what exactly he’s saying.
just you and him. this. more than just a one night stand.
you try to respond but quickly startle at the sound of three heavy raps against the door.
"is she gone? did you get her number?" a gravely voice asks, barely audible above the music.
“toji can you fuck off for like twenty more minutes?” sukuna’s not asking.
“god, fuck.” he groans softly, wiping both hands down the front of his face like it’ll somehow rid him of his humiliation.
you wait for the heavy footsteps at the door to retreat, and lean in to press a kiss to sukuna’s forehead.
“wanna get lunch tomorrow?”
shoko was going to die during your debrief tomorrow morning.
