Itoshi Sae X Reader Ft. Shidou Ryusei

˚ ୨୧⋆ 𝑑𝑒𝑣𝑜𝑡𝑖𝑜𝑛 ⎯⎯ itoshi sae x reader ft. shidou ryusei

wc: 3.7k. cw: nsfw, inc*st/stepc*st (open to interpretation), fem reader. consensual voyeurism, cucking (sae), hints of dubcon & dacryphilia, slight anal play, one mention of ryusei having a tramp stamp hehe. unhealthy relationships/dynamics. this is filth 'nd i'm not sorry ! ꒰ minors + ageless blogs dni ꒱

it's almost agonizing, the amount of red hot pleasure ryusei is putting you through - something far more intense than you've ever bargained for when giving your brother's friend that sweet, doe-eyed look. perhaps you should've listened when sae-nii told you that the blonde is no good, teeth too sharp for your tender skin and mouth too vile for the innocent, gullible mind.

but you're a stubborn little thing.

sae knows it all too well, you've always been like that after all - heart too kind for your own good and eyes awfully curious, always settling on the very things he warned you to stay away from. he should've stopped the idea from spiraling into something so very real - but if your (probably one and only) flaw is that naive, airheaded nature, then sae's must be the horrid, overwhelming yearning to see his lovely imouto ruined.

the redhead feels his chest grow all too hot as he watches the scene in front of him unfold. he could've sworn he's put you through enough filth to defile you, scrub away any trace of innocence - but apparently, ryusei really is a whole different fucking breed.

he must be - 'cause god, sae's never seen nor heard you in such state.

a shudder rips through your brother's chest, jolting him back into full awareness when you squeal, and soon enough, his vision sharpens again. tan, golden fingers tangle in your hair as shidou forces your head up from where it's pressed into the pillows. sae relishes in the way your eyes rolled back into your skull and mouth desperately hangs agape, struggling for a breath, a wheeze, anything - but the firm, rapid rhythm of his thrusts makes something so trivial as breathing impossible.

"holy fucking hell," the box blonde whistles, a crude sound that cuts through the air. "what, cat got ya' tongue now, baby?"

soft little mewls drip from your mouth, saliva pooling at the corners of your plump lips, and sae can't help but roll his eyes despite the uncomfortable throb that wakes in his pants at the sight. (when exactly did you pick up that weird drooling thing from your other brother? he doesn't tolerate the thought that maybe, he just hasn't ever gotten you to this point of mindless slobbering just yet.)

ryusei leans in when the first few babbled sounds leave your throat, incoherent with how heavy your tongue sits in your mouth. deemed unable to speak, you whine between hiccupy moans that only grow louder with each feverish thrust inside your cunt. he curls his broad frame over your back, breathing laboriously by your jaw as he listens for any cogent thought.

a laugh rumbles through his chest when he hears none. as if to force it, he crams his cock all the way up, until you jolt under his weight and give a little cry when the spongy head kisses your cervix.

"ryu-usei," you whine pitifully, a nasally, honeyed tune that makes sae's tummy simmer with need once it reaches his ears. "you're- s' de-ep!"

a condescending coo vibrates against your ear when the blonde presses an awfully tender skin to the spot just behind it. the contrast between his feverish thrusts and sickly sweet kisses turn your brains into mush.

when ryusei speaks, it's merely a white noise, muffled despite the close proximity between you.

"too deep, sweets? should've listened to your nii-chan," he laughs, as if truly amused by your disordered state. "he told ya m' a handful, didn't he?"

you force a little nod, and as if on cue, the rosy-eyed pushes you cheek-down on the mattress to face the man in question.

with your heart thumping in your throat, you swallow back a gasp when your gaze meets sae's. he looks pretty like this - with few first buttons of his silk white shirt undone, gracing you with a sliver of smooth skin, now flushed with what only you can recognize as arousal. as you glance over at the midfielder, you notice him spreading his legs just a tad wider, probably to ease the discomfort in his crotch, and note the way his eyes narrow slightly as he scrutinizes you.

ryusei swears he just felt you squeeze him tighter.

he doesn't pay it much mind, anyway. yeah, it was a little odd when sae first mentioned the only two rules for tonight - one, him in the room with you two at all times, and two, no fucking kissing - but, hey, he's not the one to look a gifted horse in the mouth. the prodigy has always been a little weird about you, too, giving you annoyed looks and rolling his eyes at your bubbly presence only to snarl at a poor soul that dared glance your way the very next second. maybe it's just how siblings are - a weird kinda push-and-pull with a sprinkle of unhealthy attachment.

well, it's not like he knows anythin' about it, nor does he give a single fuck.

not when you're here, pussy creaming on his cock and milking every single drop outta him as you squirm and whimper like he's putting you through the worst abuse ever.

drawing his hips back sloppily, ryusei glances down to where the plump meat of your ass squishes against the top of his quads. a groan rumbles through his chest, guttural as he reaches his other hand to land a harsh smack to one of the cheeks, rough fingertips soon digging into the plush - sure to leave marks for days to follow.

sae winces slightly at the sound, melting into one sick contortion with your surprised squeal, and moves his eyes to where ryusei pulls your cheeks apart. he prods his thumb at your tight little rim and you seize up, moans choked and stuttered between forceful thrusts that just won't let up. as if it wasn't enough, the man tilts his head a little lower, gathering a load of saliva in his mouth before spitting right above where his digit presses against your hole. it's lewd, overwhelming and if it wasn't for the striker's other hand holding your head in place, you would've dug it into the sheets with shame and embarrassment.

but you can't do that. instead, you ever so obediently keep your eyes forward, a little bleary still as you hold sae's gaze. your vision tunnels when ryusei presses down on your face with more force, effectively knocking the air out of your lungs along with sputtered little gasps.

you can still make out the little taunting smile that pulls at the corners of sae's mouth, charmed by your faux struggle. it’s nothing he’s never done to you before.

"look at that," a low hum resonates from above you when eventually, ryusei's finger slips right inside with ease, thanks to the additional lubrication, as makeshift as it is. "fuck, there ya go, little one."

you moan quietly, wet lashes fluttering at the delightful intrusion. as if instinctively, your hips lift off the bed in a sharp movement, pushing ryu's finger even deeper, up until the second knuckle.

you can almost hear the grin crack through his features, all teeth and borderline crazed at the way your body reacts to him.

"i think you're a little liar," the striker drawls, a throaty groan meddling with his words. "no fuckin' way you're not sneakin' behind his back, baby. you're a propher little nympho."

there's this bubbling, searing feel that's been building steadily in your tummy, and it now only grows stronger at the unintentional praise. your hips jerk against the mattress, eyes rolling backwards to meet ryusei's cherry pink gaze instead, and you both miss the way sae's hand grabs at the now achingly hard bulge pressing against the zipper of his pants.

his chest grows unbearably hot, pulse throbbing in his ears in an irregular rhythm that matches the one against his palm when he languidly squeezes himself. even through the layers of fabric, sae feels his cock fucking leak, resting heavy against the inside of his thigh and twitching with every sweet, airy sound his friend forces out of you.

ryusei isn't dumb per se, but god, he's dense for not coming to realization with any of it.

sae shudders, shoulders tense when he straightens himself and clears his vision a little. he does it just in time to see the man in question pull out of you, drawing a gasp from your swollen mouth, only to manhandle you to your back in a fluid, yet slightly rough move.

your brother almost hears the way your breath catches in your throat, heart rabbiting against your ribcage when ryusei easily mauls your legs around his waist. he digs his fingers in the doughy flesh of your hips, pulling them up slightly as he aligns himself again, and to both his and sae's surprise, you push at his chest weakly.

ryu huffs slightly, strands of icy blonde falling into his eyes as he glares down at your teary, flushed face. "what?"

you gasp when he ignores your nudging, instead prodding at your hole again, cockhead hot and slick on your lips as he slides it between them in teasing, short strokes.

"'sei, wait-" you whine in protest, hand smacking against one of his hard pecs, nails momentarily cutting through the tawny, glistening skin. "that's s'much, too much."

you're breathy, chest rising and falling so rapidly, you might as well be choking on air. the striker furrows his brows in confusion, chest heaving as he takes note of your drowsy eyes, simmering with tears and gleaming with euphoria - so contrary to your little fuss. he only rolls his eyes at the little drawled out mewls that come tumbling out your loud little mouth with each nudge on your clit, and assumes there's nothing to watch out for in the end. he eases your legs around his waist, your ankles locking at the small of his back - right where the cheeky, rough ink seeps into his brown skin - and rolls his hips forward.

head tipping back at the sting, you feel your walls stretch and accommodate to ryusei's girth all over again. his tip knocks against all the swollen spots on his way in and you whine tearfully. it's too much - all of it. he's good, awfully so, and your head feels like it's filled with cotton, stripped away from a single coherent thought. the pleasure rolls through every nerve, icy cold with the way it makes every muscle shudder, and yet it really does make you think you're on the verge of breaking.

sae-nii was a little right, after all - but it's not like you'll admit it and give him that pleasure. ryusei is a little too much than you can handle, despite how delirious he drives you, and even if every sheepish glance and desperate touch his way makes your heart flutter with silly infatuation.

"ryusei," you cry out again, and there's even a little sniffle to top off the fit. "'said- too much, fuck."

there's one thing about you that brings sae to white hot annoyance - you're whiny. perhaps it's your wide, glossy eyes and how they seem to have a way with him, granting you your every wish. maybe it just stuck to him from your adolescent years, a typical dynamic for all siblings, blood bound or not - but god does it bring him to the verge of insanity sometimes. he feels his eye twitch as you arch your back, a pretty, smooth curve that only makes your tits press further against ryusei's chiseled chest. you're squirming away, little sounds of complaint blending into the athlete's hoarse grunts and your own high-pitched moans.

sae waits, just a little bit more; gives you a chance, if you will. he only does it 'cause he's nice, and actually wants you to try and fix this attitude yourself before he steps in. after all, he knows you best - sees you in such dumb, fucked out state all too often - and he's sure you're not truly anywhere near your limit just yet.

but you don't take on the opportunity and grab at ryuisei's wrist instead when his palm goes to curl around your neck, hot and pulsating with every rapid beat of your heart. rose-colored irises lour as they settle on your face and make out just the faintest trace of a pout, more playful than truly sorrowful.

a startled yelp rolls off your tongue when a set of blunt nails digs into the supple skin on your throat, a consequence of ryu tightening his grip on your airways. you sputter for air as he gives you a firm shove, head hitting the mattress with more force this time, as if to assert his dominance.

"behave."

sae suddenly interjects from his spot on the armchair, and if only he wasn't so exasperated, he would've laughed at how quickly both of you snapped your heads in his direction.

it's low as he speaks, voice still merely a monotone hum, a warning laced between words. ryusei drags himself along your walls, drawing a strangled sound from your lips, but to his surprise, it's nowhere as desperate nor tinny as moments before.

the blonde breathes out a laugh, head tilting as his mouth stretches into a shit-eating grin when he glances over at sae. "hah? you gotta come and make m-"

sae fixes him a look, one that almost comes off as disgusted when he frowns, brows knit together. he gives the man an once-over before sighing exasperatedly, cracking his neck as he gets up from his seat.

"wasn't talking to you, pervert." he mutters, closing the gap between him and the bed in three long strides and eventually crouching down next to it.

above you, ryusei notices his hips stutter slightly, irises sharpening when the look on your face drops and makes way for a whole another expression - something he hasn't really seen on your pretty face yet. he watches as your lips part and eyes almost hurriedly follow sae's movements as he props his elbows up on his knees, leaning in closer.

in a way, you almost look nervous, if your widening eyes and labored breathing is anything to go by. there's something about this dewy appearance, a little anxious and somewhat pliant, that makes ryusei's gut stir with interest and excitement. the coil only tightens some more when sae suddenly reaches for your face, holding your jaw in a firm grip that has you yelping in surprise.

sae's eyes narrow slightly as he zones in on your face, digging his fingers into the soft flesh of your cheeks until they squish into one of these cute, irresistible pouts he knows and loves. your whimper catches in your throat and he huffs.

"stop being a brat." the redhead utters, emerald gaze piercing right through you, in all your aroused, puzzled entirety. you're getting off on this - the delightful sting from his hold, ryusei's dumbfounded stare as his movements slow in confusion. in fact, sae can almost hear the cogs turn in the faux blonde's head while he watches your interaction. he's slowly catching up, sae supposes, and the shattered holy shit he groans out only confirms his suspicions.

it's already hard enough for you to focus on anything else but ryusei and the way he grinds himself into you. slow and deep, his hips fit snugly against yours with every languid stroke that prods at all the overstimulated spots. you can feel his hand slide from your neck to your chest, fingers spreading along one of your breasts, groping at the flesh roughly as if to ground himself. truly, it's already enough to make your senses mush, a fuzzy, suffocating feeling rising in every cell.

sae's there to make it worse.

"nii-chan," you stutter, breathy as you intuitively, subconsciously lean into his touch. it's as if every nerve screams to take more. "i'm-"

"shh." he cuts in, only tightening his grip. "feels good, doesn't it?"

you can feel ryusei pick up a steady rhythm, resuming his previous pace, and the way he bullies himself into you over and over, abusing the tender flesh, puts you in a state that's nothing short of delirious. crystal clear tears gather along your lashline, mixing with the already smudged mascara, and your vision blurs.

through the haze, you can make out sae's blown pupils, alert and sharp despite how hooded his eyes are. heavy with arousal, his lashes flutter as he glances down to your lips, still luring him in, begging to steal a kiss or two, then some.

"sae-nii." you whimper again, and you almost sound in pain, sae realizes. you just might be, from the way ryusei doesn't let up his brutal pace, hips hammering into yours. you would've gone flying off the bed if it wasn't for the deathgrip they both have on you.

he doesn't mind your hand reaching for his wrist instead, clammy fingers gripping him for any sort of comfort. "think you can be good for me?" he breathes out, chest shuddering with every exhale. each of ryusei's overbearingly loud noises seems muffled by this point, but sae has to admit the way they mell into one with your sickly sweet mewls does indeed sound unbearably hot. the strain in the front of his pants might just drive him crazy any second, but that's something to worry about later.

right now, his focus is eerily pin-point, entirely on you and each of your wretched, tender reactions.

"m-mhm," you slur, sae's grip effectively turning your words into gibberish. you sound, look so dumb, so fucked out of any substantial thought. his eyes sharpen, fingers unrelenting in their hold, but you can tell from the way his jugular bobs up and down that he's losing composure fast. "pl-pleas-e, will be good f'yew, niichan."

a fresh wave of tears spills down your heated cheeks, soaking between sae's fingers. he knows what you need, notices the yearning, pleading look you give when peering up at him. by this point, it's second nature. you're easier to read than the back of his hand.

it's downright filthy, all teeth and tongue as sae kisses you, mouth molding against yours as he licks into it with vigour. you're drooling a little, just a tad too eager, but sae doesn't actually mind. not when the warmth in his own chest is almost lethal, euphoria in every breath as he devours you, inch by inch, greedy hands roughly grabbing at every exposed piece of flesh.

ryusei fucks a little too well for someone as shell-shocked as he is - or should be, at least. it doesn't seem like he's all that affected, yet alone bothered by the taboo that plays out right for him to witness. if anything, this twisted sort of infatuation between you and sae and the sticky sweet, slick sounds you make when kissing your brother so eagerly may be just the very things to haul him over the edge.

"shit, shit- m' gonna cum, fuck, i'm filling ya up." the striker drawls out, blood rushing between his ears as he chases the familiar sensation. somewhere between unrelenting thrusts and throaty, treacly groans, he slips his other hand between your thighs - only to find sae's fingers already there, rubbing sloppy circles into the throbbing nub.

"don't y' dare," sae grunts, the warning muffled by your tongue lapping at his own still. (god, ryusei thinks, you're gonna make him choke on you, and the entirety of this sick and twisted whatever you two are.) "have some fucking manners, idiot."

he ignores the whining sound that slips past ryusei's mouth, all of his attention on you now as he selfishly, greedily gobbles up every stammering gasp right from your lips. sae feels them wobble, tongue heavy against his own as you struggle to keep up between the irregular bucking of your hips against his palm and ryu's cock still pistoning in and out of your creaming cunt. you're close, he can tell - doesn't even need to listen to your desperate, hiccupy mewls.

"i know, i know," he could've cringed at how slurred his words come out, but there's no place for any shame anymore. sae feels your poor little clit jolt under his touch, rubbed raw from his fingers that only press down harder on the nub with each of ryusei's thrusts.

"cum for me, 'mouto. show me, 's okay."

you start to tremble in his hold, breath hot on his mouth as you babble without a drop of sense, and ryusei holds your hips down while he crams his cock against the sweetest spots. sae can only imagine how tight it feels, to be plowing into you as your little pussy swells and creams, quivering with an orgasm so intense your voice dies in your throat. he wonders how sick it is of him to get this phantom sensation as he watches you fall apart and grip onto him for dear life - his cock twitches against his pants, and it's almost as if he can feel you ooze around him and squeeze his girth so hard, nothing else could ever compare.

sae's almost jealous, wishes that it could be him you were clamping down on in ecstasy. but he's nice tonight. he's a good brother, and an even better lover. (perhaps one ties closely with the other.) just once, he can be generous and grant you your silly wish of having your favorite striker fuck you unconscious - it's not like it matters in the long run.

it doesn't really matter, as long as he is the one carving your sloppy, eager cunt to his shape; branding the supple skin of your décolletage with marks that scream ownership. and it's always him, and you're always so obedient and pliant, a perfect doll for him and all his desires, as carnal as they might be. maybe giving in to your pleading, bambi eyes, therefore allowing all of this to happen, wasn't actually that bad of an idea, sae thinks. he doesn't mind spoiling you rotten, not at all.

in the end, it's still him your bleary eyes search for as pleasure consumes you. it's his name on your lips as you fall apart.

“are you alone?”

when the conversations start like this so late in the night, you know what’s about to happen. still, it does manage to cut you off guard- even just a little bit. so you weren’t able to hide the hitch in your breath very well. just like he wasn’t able to hide the low, low chuckle that followed immediately after your quiet admission of guilt. you know him too well. and he, you. 

“maybe” you draw out, voice light and airy and playful as you respond into the phone. he laughs again at your attempt to play coy because you both know what you’re doing. it’s the same thing every single time. you both know that you’re taking the phone and the line and sitting on the edge of your shared bed- the one that always feels so empty and cold when he has to stay away from home for a night or two. you both know that right now, you’re listening very, very carefully for the pitter-patter of tiny feet or the quiet creaking of the bedroom, hoping you don’t have any uninvited young guest scampering around past their bedtime. “are you alone?”

and you both know that you’re now lifting up the edges of your nightgown and slipping your panties down to your ankles now that you know that the coast is clear and your husband’s loving voice is purring in your ear.

“you know I am, sweetheart .” he hums at the sound of your sultry voice and the call of his title in such a lewd manner. and you’re almost too ashamed to admit just how turned on a few words make you. but you can’t help it. it hasn’t even been that long yet, and you already miss him. your body- the parts now being uncovered in the chilly air of your bedroom longs for his touch. goosebumps are already littering your skin and your nipples are perking up and pebbling. almost as if he was here, right beside you. ready to keep you warm, and safe, and most of all? “are you touching yourself for me?”

keeping you loved.

you smile into the phone as you opt not to rely at first. instead, you decide to lie back on the bed. letting the familiar smell of his side of the comforter surround you as your body makes contact. the phone line tugs and stretches a little bit as you bring it with you. but you’re able to bring it up to your ear and tuck it in your shoulder all nice and snug without too much trouble. And with you let yourself get comfortable. hiking up your legs and placing your feet flat on top of the bed. drawing up your nightgown even further. and resting your hand in the valley between your breasts and letting your hands move around on their own. touching your breasts. brushing your fingers against your skin. like you wish he could. like you  know  he would. if only he was here.  if only, if only.

“maybe I am, ” You say into the phone, repeating the same sing-songy tone that you had on earlier as your smile grows just a teensy bit more. “maybe I’m not.”

almost instantly, you hear a sigh. on the other side of the phone, you know gojo is getting a little impatient with you. you don’t blame him too. you know how hard he trains. and you can imagine just how long of a day he’s had. barking orders at those who never seem to listen. the training he endures that never seems to end. and so many more things that you know you’re not privy to, especially after his climb in the ranks. but you can’t help it. you just can’t help it. he left you alone here. alone on the bed. alone, alone, alone with only his voice to comfort you. 

so of course you were going to give a little tease. just a little one, at least. because it’s only natural. because it’s only fair. because he’s doing it to you right now. 

just letting you hear the sound of his voice and not the warmth of his hands. 

“sweetheart, ” he calls out to you through the phone, voice strained and breathing a little tighter than before. out of instinct, you find yourself licking at your lips and biting them as the hand on your chest slowly travels down, and down, and down. you know the sounds that follow after all too well. the rustling of clothes. the quiet clinking of metal. the soft groans. it’s telling.  too  telling. the hidden neediness in his voice. the subtle way he begs with just the call of a nickname.  your  nickname. it’s telling. because you know him just as well as he knows you. “i need you to touch yourself for me.  please .”

because you know him.

and because you know him so well, you  know  that he’s gotten started without you. you can just tell. he has already gotten started without you. maybe it was while the phone was ringing. maybe it was while you were still talking- still  teasing  him. maybe it was even before he decided to call you. But you can just  tell . that he’s already pulled down his trousers. that he’s already pulled out free his cock. and that the sounds you heard were him freeing himself even further from the confines of his clothesand his determination to be the best striker. because more than his resolve, he wants you. he  needs  you. he  misses  you. as much as you feel all those same things for him.

and suddenly you don’t  want  to be a tease. suddenly you don’t want to make a big show about touching every part of your body except that he wants you to- that you  need  to- the most. suddenly you realize that you just want what you wanted all along.

him.  

“I am…” you tell him in a rush, just as your fingers find some of the wetness pooling in between your legs. you swipe it- coating some of your fingers tips with your own arousal and go immediately for your clit. you draw a sharp breath, feeling your own sense of neediness crop up now that you’re touching the most sensitive part of your body. but you don’t want to stop there. so you don’t. you reach out your other hand and take a fistful of one of your boobs. grip firm and tight like the way satoru does to you. you squeeze at it before moving your fingers along to play with your nipples. pinching them and rolling them so carefully between two fingers that it starts getting your hips shifting and your voice rising in a way that you imagine is unbefitting of a young woman. but you don’t care anymore. you don’t. because right now? you just want to close your eyes. you just want to block all sound. but most of all? “ I am, toru…I’m touching myself….all for you .”

you just want to focus on him.

“all for me, sweetheart?” 

because maybe if you focus hard enough. maybe if you imagine hard enough.

“a-all of you.”

if you  wish  hard enough.

“there’s my good girl. ”

then maybe the warmth you’re feeling now will start to feel it does when he’s the one touching you.
