a/n: this is author's first smut ever, first ryuusui fic ever, and second fic to reach above 5k. guys i'm scared. thank u to uh sai, p1erce and meo(?) for reading this before i posted it i'm dying. and YES that is a will wood lyric title

you hate nanami ryuusui.

you hate his golden hair, his brown eyes, and that arrogant fucking grin on his face.

you hate that little fingersnap he does, that little "ha-ha!" each time.

you hate him. period.

so why are you doing this?

ryuusui's lips slid against yours easily, softly, perfectly, like this wasn't spontaneous and it was threaded into the very plan of the universe itself.

his hands, once on your shoulders, slide down to your waist. it almost irritates you how well he fits against you like this, but you're a little preoccupied with the tongue down your throat to think about it.

(you're a little distracted, too, by the way the sunset through the classroom window paints his golden hair and pretty brown eyes. how could you keep hating him like this?)

you're still gripping the edge of the teacher's desk like your life depends on it when he pulls away, a little dazed. pretty, pretty, pretty, your mind repeats, seeing his kiss-bitten lips and the flush on his cheeks. god..

you were almost too busy staring at the face of your once sworn rival, how the light frames it just right and his hair is a little messy from the hold you had on it a few seconds ago, and— fuck, keep it together, y/n!! you still fucking hate him. 'once sworn???' hell no. you still hate him. hate him even when he lowers down to his knees with that infuriating smirk on his face. hate him even if you let him spread your legs a little wider, hate him even if those hands on your waist are wandering lower and lower and you're just letting him—

the cloth of your skirt is bunching up at your waist. your hand makes its way into those golden locks again, pulling just the slightest when he nibbles at your inner thigh. you hear him whine a little, and it makes you wonder how much of a masochist he must be to like that. you tug again, and the noise he makes is almost.. cute.

cute, until one of his hands makes its way between your thighs. cute, until that hand slides the gusset of your underwear to the side and you can feel how much slick has gathered there. cute, until the palm of that hand starts grinding against your clit and fuck, where did he learn to be so good at this?

you bite down hard on your lip, trying to keep your noises to a minimum because god forbid nanami ryuusui gets an ego boost from knowing how well he's doing his job.

..it's a little difficult when he's doing that, though. the way his fingers are tapping at your clit now, touch featherlight like he's teasing you on purpose, or the way they slide through your slit, almost poking in. almost.

it's like he wants you to beg for a chance to cum. well, he's not getting what he wants. not at all.

even if he looks up at you with those chocolate eyes and that smug little smirk and he pushes a little harder. even if you can feel the puddle of slick gathering between your thighs and the absolute mess it's making on the teacher's desk. even if it feels so good, like you're about to ride cloud nine, but it's not enough, goddammit, please—

you don't realize you said that last bit out loud until you hear ryuusui laugh, and shit, you hate that laugh, you've hated it for a year, but it was followed by him sliding his fingers through your slit and finally, finally you're not clenching around nothing anymore. fuck, it feels so good, too, almost enough to make you forget you hated this guy.

that thought gets banished when he crooks his fingers and they reach that fucking spot, and shit, shit—

you can't help but let out a moan at that, and from the way he's looking at you you know ryuusui saw that. you'd be mad at how much more satisfied he looks if not for the fact he does it again, along with his palm still grinding on your clit. you wonder vaguely if all your mutual hatred for each other had malformed into some sort of urge to turn you into a fucked out mess for him, because he was doing a hell of a good job of it.

every time he hits that damn spot, you jolt like an animal caught in a trap. your noises are reaching levels you'd be embarrassed about if you weren't losing your mind right now — little ohs and ahs over and over like a broken record player.

finally, the bastard (can you really even call him that when you're whining so pretty for him?) speaks, still with that cocky voice you definitely, totally, always hate—

"hah! everyone knows we hate each other's guts," he starts, voice smug as ever with the slightest undertone of lust added to it. he crooks his fingers again as he continues, "but when you're like this? so fucking pretty—" you cut him off with a whine, and he laughs. god..

you've never heard him swear as much as he is now, and it's doing wonders to your already fucked up brain. when did you stop thinking of ryuusui as an irritating rich boy classmate and like this?

he grinds the heel of his palm against your clit, and you know that if he does it again you're going to cum. shit, it's like you already did, with the mess of slick coating your inner thighs and soaking the skirt bunched up at your waist.

seems like he knows that too, the little fuck, because ryuusui pulls his fingers out just as you let out a whimper. his fingers are still there, ghosting over your clit, but fuck it, that's not enough.

you muster up just enough of your energy left to beg. you're not sure at what point you let yourself drop this low, but fuck it, you need to cum so bad.

"why'd you— hnn! why'd you pull them out.. please, you bastard, let me cum—!"

you sound like a brat right now, demanding it from him, but fuck it. to you, that's what he sounded like every day of your life — "i desire this, i desire that!" — and he always got what he wanted. always. so it was his turn to give you something now, right?

luckily for you, your helpless whining was exactly what he wanted from you.

still with that maddeningly smug little grin, ryuusui slips his fingers through your slick again, gathering as much as he can, before bringing his fingers to his lips and sucking.

the show he makes of licking your juices off his fingers is a little too much for your fried brain to comprehend. one second, he's murmuring something about the way you taste ("much sweeter than the foul words that usually come out of your mouth," or something like that) and then the next, it's not his fingers between your legs anymore, it's his head.

you tug hard at his hair as he eats you out, and you wish for a moment he wasn't nearly as good at this as he is. you don't know how the fuck nanami ryuusui learned to do this shit so well, but his tongue on your clit was something you did not want to stop at the moment.

you're sure he can tell that, too, from the fucking noise. god, you're lucky it's way past dismissal time, if people were still in the hallways you'd both get caught. the way he groans into your pussy, or the whine that claws its way up your throat right after — there's no way you wouldn't get suspended for this if someone were here.

good thing they aren't, then.

"f-fucking playboy, oh shit, that's— nngh!"

every time you try to speak, try and insult his stupidly good skills and stupidly good looks and stupid everything, you cut yourself off with your own moans, and god if ryuusui isn't pleased about it. you can feel him grinning into your wet heat, before he dives back in with twice as much vigor.

"playboy, huh? i'll take it, as long as i can get a taste of this sweet cunt."

it's infuriating, how the tone of his voice is almost perfectly calm and yet you're already an overstimulated mess. you hate it. hate everything about him.

you hate, most of all, how hard nanami ryuusui is to hate when he's doing this to you.

you tug hard at his hair as a 'fuck you,' since you can't muster up the words right now, and the whine you get from him is almost enough to satisfy your need for revenge. almost.

"hate you," you whine, even if your whole body trembles at his touch and your cheeks are more flushed than ever. "hate you— fuck, hate you so much, hah!"

you hate him even if he laughs, even if you're spreading your legs wider for him, even if the way his tongue laves over your clit and his fingers curl into your g-spot is going to make you cum hard.

speaking of that, actually—

his head is buried between your thighs now, licking and sucking at you like a man starved. the pool of drool and slick between your thighs is getting larger and larger.

"mngh, n—ah!—nami, you fuck!" your grip on his hair is even stronger now, as you feel his little whines grow louder. he really likes your taste, and your hands in his hair apparently. greedy fucking masochist.

"you taste like the divine," he murmurs softly, softer than he's ever spoken to you before. looking down at his place, kneeling before you and head between your thighs, you'd think he was a devoted worshipper taking care of his god.

(actually, who says he isn't the god? now that you're drunk off pleasure and losing your mind, you can admit ryuusui is pretty. prettier than anyone else in your class, hell, the whole school, even if you argue with each other endlessly. for goodness' sake, you would have liked him to fuck you a long time ago if it wasn't for his damn playboy personality.)

"shut up, you f-uh— freak, we're literally in a classroom!"

"says the one enjoying it," he retorts, and he sucks on your clit harder just to spite you. the little 'oh, fuck!' you let out makes him grin.

in your haze of pleasure, you can tell you're going to cum soon, and maybe ryuusui can too, because all of a sudden he speeds up his work, and it breaks you.

"fuck! nanami you fffucking— please, nnh, please please make me cum, god—"

your grip on the edge of the teacher's desk is tight enough it feels like you're going to shatter it, and you're tugging at ryuusui's hair harder than ever. you can hear his little noises even through the haze, and they're only turning you on more.

"mmnh— shit, please, i'm so c-close, r-ryuusui—!"

something about the fact you said his first name instead of his last makes the last of ryuusui's restraint fucking snap.

he's never liked you. ever since you bitched about him being such an "arrogant rich kid who wanted too much," and ever since you kept looking at him with that damned glare of yours.

he had to chase you. run and run and keep being so annoying that you couldn't help but pay attention to him.

brat. honestly, the both of you are. arguing and bickering and always turning every little assignment into a competition.

it just makes him want to fuck your brains out more, though.

so when he has you whining so prettily for him, while he's on his knees, head between your thighs?

god, he's going to take advantage of that.

he can see the tears gathering in your eyes and just how flushed your face is, and he wonders why he didn't do this sooner. after all, ryuusui takes what he wants, when he wants it.

and right now? he really, really fucking wants you.

he thrusts his fingers into your sopping wet cunt again, slamming them into your g-spot just to hear you squeal. the taste of your slick on his tongue is making him lightheaded with how good it tastes — fuck, does ryuusui even still hate you anymore?

he chances a look at your face again, tears flowing down your cheeks and the most sinful moans slipping out of your lips, and he can't bring himself to say yes to the damn question.

instead, he uses his mouth for better purposes — like sucking at your clit until you're begging him to stop.

you do the opposite.

"ahn—! ryuusui, please, don't s-stop, please, m'gonna cum—"

your pleading earns you one last hard touch to your g-spot and a nibble on your clit to help you over the edge, and you scream.

"fuck," ryuusui mumbles, staring up at you from his place between your legs. you look unfathomably beautiful like this, with the last remaining bits of sunlight on you, uniform crumpled and messed up and pussy clenching around his fingers.

and damn, he wants more of that. preferably right now.

he dives back in with renewed vigor, licking up your juices and getting mesmerized at how your cunt just keeps sucking his fingers back in with every thrust. you're whining, fucked out from the overstimulation, but your body still wanted more.

and ryuusui would be damned for lying if he said he didn't want to give it to you.

"mngh—!? r-ryu—" you cut yourself off with a yelp, tugging at his hair again as the pleasure washes over you.

it's too much.

and ryuusui isn't fucking stopping. at all.

he's still eating you out with the energy of a man on his final meal, and those damn fingers wouldn't miss your g-spot for the world.

your mouth stays wide open now, your moans and whines clawing their way up your throat and out. "ah, ah, ah, a-ah— ah! please—"

ryuusui bites back a groan at that. instead, he replaces his tongue on your clit with the heel of his palm again, grinding against it, so he can taunt you.

"please what? god," he mutters, looking at the pool of slick you've made, "if i keep going, you're going to squirt, aren't you? all over my fingers?"

too out of it to understand his words, you nod mindlessly, whining. "yes, yes, unh, s'too much, fuck, ryu— too much—!"

with one last motion against your clit, he does end up making you squirt, leaving you spilling all over his fingers and tongue.

ryuusui can only watch, mesmerized, fingers still loosely thrusting in and out of your cunt as you whine.

and of course, as greedy as he is, as insatiable as he is, he wants another taste.

he licks up some of your squirt and moans, loud enough you can hear him through your sobbing gasps.

god. god.

when he finally pulls out his fingers, you let out a soft whimper. eyes half-lidded, you see ryuusui rising from his place between your legs to kiss you again. your hand in his hair moves down to the nape of his neck, still pulling at those golden locks.

you really can't say you hate him anymore. not at all. not when you whimper into the kiss like that.

you don't know what part of your brain makes you think this — probably the most impulsive bit of it — but you want to return the favor.

god. the image of nanami ryuusui, whining pathetically and face flushed as you ruin him slips into your head, and you love it.

"your turn," you murmur, and even if your whole body is still trembling you know exactly what you want to do.

you slide your legs off the teacher's desk, pulling yourself off it until you're the one on your knees, between ryuusui's legs. he seems surprised at the turn of events, and.. damn, is he blushing?

cute.

"wait, what are you—"

his words are interrupted by the sound of you unbuttoning his pants. ryuusui's breath hitches, and he's still looking at you like this was unexpected.

honestly, it wasn't. what was so wrong with you wanting a taste of him, too?

now that he's the one pressed against the teacher's desk, you pull down his pants, and his underwear too, for that matter, and take his hard cock in your hand.

the noise he gasps out makes you grin. just to test the waters, you lick a stripe up the underside of it, and you hear him whine.

shit, that was hot.

"didn't know you would taste this good," you comment, and just before he can grit out a retort you roughly take his tip into your mouth, and whatever ryuusui was going to say comes out as a choked moan.

"shut up," he mutters, and for his insolence you suck a little harder, and the whimper that follows his words satisfies you well enough. maybe.

you come off the tip with a little pop, switching to lick at the base instead. regardless of where you do, though, the little noises he's making are constant. you find that for once you like that.

you try your best to swallow down all of him — you keep going til the tip hits the back of your throat, and the moan he lets out when you do that is fucking sinful.

you swirl your tongue around the tip of his cock a little, bobbing your head up and down like you think you should. you want— no, need to see what ryuusui looks like when he's fucked out.

speaking of him—

ryuusui didn't actually think you would do this, let alone voluntarily. your lips were so pretty wrapped around his cock, and shit, it felt so fucking good.

the way you were looking up at him like you needed to do this, sucking him off after letting him make you squirt in an empty classroom?

it turned him on more than he was willing to admit.

his hands slip into your hair, a little roughly, and they tug. he almost thinks you don't notice, until you suck a little harder and he chokes on a gasp.

your pace quickens, and ffffuuuck, ryuusui likes that. he doesn't know how you're good at this, but he can barely form coherent thoughts anymore, let alone words. the only things coming out of his mouth are soft moans mixed with "please—"

"please what?" you come off his cock again for a moment, replacing your mouth with your fingers to respond. it's a bit petty, throwing his own words back at him, but the long, drawn out whine it gets out of ryuusui is so fucking cute it should be a crime.

with your fingers, you slow down the pace a little, to tease the damn brat. he was already saying please, it shouldn't be too difficult to make him beg, right?

the way he looks almost makes you want to take mercy on him. the remaining light of the sunset through the window is fading slowly, but it still compliments his golden hair, and the flush on his cheeks makes you want to ruin him more.

you keep taking it slow, anyway, pumping his cock at a leisurely pace. you won't tell him outright to beg, no, it'd be much more fun to watch him do it of his own accord—

"please," ryuusui breathes out, panting, "please, i want— need more, hng—"

fuuuuck.

you're kind enough to oblige that sweet little request, sliding your fingers up his cock a little faster. just a little, to keep him on edge.

his hips rock forward softly, trying desperately to chase the pleasure you're withholding from him. he gasps out another "please," and you know what he wants. you sigh, muttering "spoiled brat," and do it anyway.

you take the tip back into your mouth, your fingers at the base. when the tip hits the back of your throat, your eyes flutter shut. god, you could stay like this forever. you weren't lying when you said he tasted good, and the helpless whines he's making are music to your ears.

"s'good," he murmurs, already dazed, high on pleasure and losing his mind. you think you prefer ryuusui like this — one hand on the desk to keep him balanced, the other tugging uselessly at your hair while you suck him off.

"fuck," he whines, hands tangling further in your hair. you curl your fingers around the base where you couldn't reach, and he lets out a groan.

your voice is muffled around him, but you manage to get out a few words still. "want to taste you," you breathed out, tightening your fingers a little. as he gasps, you continue, "wanna take you deep, mmh.."

"don't talk like t-th—ah!—at," he stammers, his hands in your hair turning into fists. the pull doesn't bother you at all — just tells you you're doing a good job.

that in mind, you swallow around his cock again, and you can already taste a few drops of pre-cum on your tongue as you do so. fuck, even that part of him tasted so fucking good.

you can feel the way he's trembling in your hold, and the way his little "ah ah ah—!"s are getting louder. he thrusts his hips a little harder subconsciously, and you can tell he's going to cum any moment now.

you double your efforts, taking more of him down your throat as he chokes on a moan. you quicken the pace your fingers have been moving at again, and you swirl your tongue around the tip one last time before ryuusui breaks.

"fuck—!" his hand grasps at your hair almost painfully as he cums, holding on like you're a lifeline. you do your best to swallow everything down, taking his cock to the hilt. a few spurts of white still leak out of your lips, spilling over onto the classroom floor.

ryuusui is left panting, balanced between his grip on the teacher's desk and you.

he looks pretty like this, you think as you pop off his cock, licking your lips for the last few bits of cum.

you can tell he's staring at you as you do so, and just to spite him, you don a smug little smirk surprisingly similar to his own.

"..y'know, you're not half bad at this," he mutters, looking almost bashful, averting his gaze. the red flush on his cheeks isn't helping his look, either, and you giggle a little.

when ryuusui looks back at you, with that satisfied grin on your face and licking his cum off your fingers, he finds it extremely fucking difficult to imagine ever hating you again.

you weren't exactly the kind of picture-perfect image they wrote about in classic literature, considering the situation — however, ryuusui doesn't give a shit about that.

kneeling down at your level, he kisses you again, only softer this time. he feels your hands come back up to their place in his hair, and his hands make their way to your waist again.

thank fuck this all happened when no one was in the damn school building.

you separate for only a moment, gasping for breath, before you dive back in like you're starving for his lips. he obliges you, deepening the kiss, before parting again, both of you panting heavily.

you'd crawled onto his lap, now, nuzzling your face into the crook of ryuusui's neck before biting softly, delighting in the whine it earned you.

his fingers slip back under your skirt, and you shiver in his hold. "enough prep already," you hiss, but you whimper when the pads of his fingers rub at your clit anyway.

well. this was going to be a loooong stay in that empty classroom, then.

you grind your hips down on him, just to hear that little noise he'll make. your slit catches on the tip of his cock as he gasps, still sensitive.

you tangle a hand through his hair and tug a little to get his attention. "oi— shit, nana—ryuusui, do you have a condom on you?"

"no," he answers, but the lopsided grin on his face tells you he's just fine with that information.

"fuck you mean no?" you're about to pull yourself off already, hopefully able to pretend this never happened, but his hands, still on your waist, keep you there. what the hell?

honestly, you're much more horny than terrified right now, but still.

"let me off," you mutter, yet there's little conviction in your words. "we can't do it raw, dumbass, there's always—"

"a risk?" ryuusui clicks his tongue, and his hand on your waist starts slipping lower.

"just a guess, but you're on the pill, right? am i wrong?"

"..yeah," you admit, averting your gaze. how he guessed that you have no fucking clue ('sailor's instincts' or whatever), but he is right.

his fingers are tracing circles on your inner thigh now, and his grin only gets wider. ryuusui leans in closer, until his lips are right next to your ear.

"mm.. well, if it comes down to it, i'm not one for avoiding responsibility," he whispers, and you pray to god he doesn't feel the way you shuddered at that. his tone is satisfied, like he's daring you to say no.

"but still— mmh!" before you can properly try and reason with him, he bites at the base of your neck, and you yelp. those fingers of his are sliding closer to where you want them, too, and ssshiiittt..

you nod once, twice into the crook of his neck, one small "yes, please," leaving your lips before you let him lower you down onto his cock.

when he bottoms out, you jolt, your hand in his hair tightening its hold as he groans. "fuck, you're tight," he bites out, thrusting up into you once to hear you mewl.

the stretch stings a little, but it's the kind of pain that makes you whine in the best way possible.

you could definitely get over all your hate for the guy like this.

you can feel your slick gathering where your bodies meet, each slide accompanied by a wet shlick noise that made you very glad you could keep your face hidden in ryuusui's neck.

your noises are muffled by that too, but clearly the greedy ass man under you isn't happy with that. "let me hear you," he demands, fingers returning to their spot at your clit. he delights in the moan it steals from you, as his other hand keeps you steady on his lap.

when another thrust into your cunt hits your g-spot just right, you cry out, whining as ryuusui does it again. "hnngg— harder," you breathe out, hand tugging harder at his golden locks.

"what's the— ah — magic word?"

you're very suddenly reminded of why you hated him and his stupidly arrogant behavior, and yet you can't bring yourself to deny him his teasing.

"please," you say, biting back a moan and a sharp retort as you do so. you feel him adjust his hold on your waist, lifting you up a little. you're about to complain over the loss of feeling before he slams you back down, gently yet hard, just like you wanted.

you yelp, your other hand sliding up his back to grip his shoulder. you can already feel tears of pleasure pricking at your eyes. fuck.

each thrust into your wet heat leaves you breathless, whining as ryuusui groans.

"shit," he chokes out when he slams you back down again, panting heavily. "do you have any idea how fucking hot you are like this—"

"shut up," you retort, even if you're still gasping for breath at his actions. "shut the hell up and fuck me—"

"mmngh, fffuuck!" he bites his lip, and out of desperation or pure instinct he thrusts his hips up into yours at the same time you shift down, and you scream.

"hnghh—! again, ryuusui, please, ah—"

your pussy clenches around his cock and he whines, doing as asked, over and over and over until you're both trembling.

the fingers on your clit press a little harder, and you squeal, the tears in your eyes spilling over down your cheeks.

you grind your hips down to get him a little deeper, and you can hear ryuusui sob at that.

you feel, too, from the franticness of his movements to the way he whines that he's close, still sensitive from earlier.

"don't you dare fucking cum yet, you idiot— haah!" tugging at his hair to emphasize your point, he mewls, only bucking his hips up more. "m'so close, please," he cries. "wanna make you cum, wanna— fuck, want to see you cry f'me—"

he makes good on his wishes, hips slamming into yours as you whimper. each thrust makes your slick slip down your thighs onto his, the slide easy with the sheer amount of it.

your brain is turning to mush, mind reduced to 'please' and 'faster' and gasping out ryuusui's name like a lifeline. he hits your g-spot every time he slams your hips together, and you moan like you're in paradise. "ah, ah, ah, uh, ah, unghh—!"

you do end up crying for him, your tears staining the collar of his undershirt as you bury your face in his neck. "fuck," you whimper, sensitivity at its peak, "fuck—!"

you cum around his cock, your juices pooling under you as you whine, hands still holding onto ryuusui tight.

"ssshit, that was— mmh!" he cuts himself off with a groan as he feels your pussy tightening around him. chasing his own release, he grinds up into your sopping wet cunt. you cry out at the overstimulation, but he pays little thought to it, lost in a haze of pleasure.

"please, please, m'gonna— fffuuuckk!"

ryuusui cums, filling your cunt as you whine. he stills, biting at your neck again to keep himself grounded.

when he looks down at the place where your bodies are connected, he notices a ring of slick and cum around the base of his cock where it had leaked out of your pussy.

fucking hot, he thinks, still a little dazed. you're still trembling on him, face flushed and tear tracks on your cheeks.

you lean in again and crash your lips onto his in a kiss, whining into his mouth when he kisses back.
