rin-nii?

he turns his head to the door before you're even finished speaking or the turtleneck rests around his throat comfortably. he'd like to think it's just his quick reflexes and attentive nature - but that would be a blatant lie, something to drown out the wailing of his morals as they get crushed under your foot when you step into the bathroom.

(he's not a liar - he's known for many traits, and one of them is his unfailingly sharp tongue and honest nature.)

you look stunning as ever, a dusting of pink on your cheeks - a result of the past hour you've spent in front of your vanity - and he just knows you're so well aware that he loves this look on you. if you weren't, there would be no trace of that little sparkle in your eyes, a playful glint behind the curtain of thick lashes.

it's a little game you're playing, one that's so different from the many different ones that you've engaged in during your childhood years.

(but then again, nothing is the same as it used to be, isn't it?)

rin wishes that the immediate switch of his attention whenever you are around was an effect of his observant, always alert temperament. that he was this way with everyone else, teammates and friends or maybe even reporters and fans as they surround him after a game.

but it's not, and the realization is pushed to the back of his mind as quickly as it appears, pulling at his heartstrings and tightening their loop.

he knows, god of course he knows that it's because you're his little sister.

it's always been this way, ever since his parents brought you home for good. big, hopeful eyes, hiding behind long and luscious lashes that mirrored his and sae's so much, people would laugh and say that you were meant to be family - the very first time he saw the look on your face, he made it his goal to always keep you safe and sound. he's never really felt anything like it before, maybe because he was the one looked after until that point. their relationship with sae was sweet, something every parent would wish to see between their children - a shared passion bringing them so close, their bond was unbreakable.

until it wasn't, and a mere thought of the eldest itoshi sibling was enough to make you weep into the pillows. it was something rin would listen to through the wall separating your rooms, wishing, hoping he'll eventually find a way to make the pain subside - all while dealing with his own heartbreak that made his chest ache and the discoloration under his eyes grow deeper.

oh, if he knew. if only there was a sign, a single warning that the way to heal you both would be everything you could ever wish to experience and feel, but nothing you should be going through with each other.

"are you done? mama called, said they're almost at the restaurant already.." you say, fingers fiddling with the hem of your dress.

he hums under his breath, turns back to face the mirror and fix the wool around his neck, tucking the sweater into his black slacks. "yeah, you can go get your shoes on, love."

sometimes, when the weight of your relationship settles down on his shoulders and eats away at his conscience, he remembers that it takes two to play out the filth that silently stains your family name.

usually, the reminder comes in a form of touch - light but sensual, feigning innocence but it has played out too many times before to pass as accidental. and now, it's there again. a pair of arms sneaking around his slender waist, hands gently grabbing on the flesh, fisting at the smooth fabric of his sweater.

you press your temple against his shoulder blade, a soft hum slipping past your lips as your hands slide lower, subtly pushing away rin's own as he's about to fasten his zipper.

"i wasn't rushing you, though, nii-chan." it's breathy, a teasing drop to your voice as nimble fingers push up the hem of his sweater, then dip past the elastic of his boxers. "told her we'll be late."

rin watches in the mirror as your hand eases his already hardening cock out, grabbing at his balls and making him suck in a breath. you wrap your fingers around the very base of his length, the girth too much to let you circle your hand fully, and you sigh softly against his back when he tenses up.

"stop," he rasps and moves to grab at your wrist. "of course we'll be late, you took fucking hours to get ready."

it's a bit harsher than he wanted it to be, but you turn a deaf ear to it. in fact, there's a slight chuckle coming from behind him as you give his cock an experimental stroke - firm and languid, something to try and ignite the familiar pull in his tummy.

he swallows back a moan then forces your hands off of him, more bluntly this time, before tucking himself back in.

"you're no fun," your mumble bleeds into something bordering a whine as rin turns back around to face you and grabs your jaw, hard. "mean, even."

it's jumbled through your pursed lips, pinkish pout looking so taunting to rin as he glares down at you. but it's still playful, pulling at his restraints as you go the extra mile to bat your eyelashes at him.

he groans.

"stop playin' around," he mumbles, then leans down to press his mouth to yours. it's sweet but firm, makes you grip at his sweater and stand on your tiptoes, chasing the feeling of his tongue pushing against your own.

a slap echoes through the bathroom as he smacks your ass, the surprised squeal muffled by his lips before you manage to tear yourself off of him.

"hey!" you exclaim, brows furrowed, but your hands move to smooth out the fabric of his sweater anyway. "this was uncalled for."

he looks down at you, an amused kind of smile pulling at his lips and despite the unsatisfied heat pooling in your stomach, it makes you smile right back. simply because while he's grown a bit softer over the years, compared to his teenage self, the sight of your step-brother smiling was still seldom and something to behold.

"yeah, sure. don't play dumb with me, pretty." he gives your bottom a gentle pat instead, as if to soothe the heated skin and rush you at the same time. "now let's go, don't want to keep 'em waiting."

as you press one last peck to his mouth and turn to step out of the bathroom, right into his bedroom that now the two of you share whenever you come back to kamakura, there's a strange sensation of relief washing over his regretful heart.

if what you're doing is beyond salvation, then the both of you shall rot together.

'cause he never was the lone sinner - if anything, you were even worse.

✧

for a brief second, you wonder if anyone can tell.

the waiter, an elderly man that you vaguely recall serving you even years back when you were children, that now gives a small nod and leaves your table after filling your glasses with deep maroon wine; your mother, as she chats with your father about something you just couldn't pay attention to; and finally, your eldest brother, as he sits right across from you at the mahogany table - turquoise eyes looking as bored as always, which only makes your thoughts spiral further.

does he know?

if so, then he mustn't be surprised at all, judging from the monotone look he gives you - but then again, his indifference also should worry you to no end.

because what you're doing is objectively wrong. goes against anything your parents ever put in your head, the ethics that they made sure you held close to your heart until the end of time. it's wrong in every way possible, but somehow, it never kept you up at night, not even once. maybe because it started years before your sense of morality formed, brain still in process of putting itself together. maybe because when you first looked at your nii-chan as a boy, and not just your brother, you were merely a stupid teenager, struggling to fill the void that sae left by going to spain and then coming back only to wound you with venom in his words.

either way, you're just curious - if anyone ever just thought of you and your precious, lovely nii-san being anything but just siblings, a loving family bound with a bond so strong, he felt the need to show you the world and bring you along with him when he left to pursue his career.

you want to think that you wouldn't care, ignore the judgement and just grab at rin-nii's arm, look up at him with nothing but trust and unconditional love.

but deep down, you know - you feel the dread as it gnaws and eats away at your insides, the fear almost substantial - that if they were ever to find out, you'd want the earth to swallow you whole.

"got any boy on your radar, sweets?"

your eyes are absent for a second longer as you turn to look at your mom - who smiles at you from her seat, warm but amused at your zoning out.

"h-huh?" the slight furrow of your brow makes rin snort from beside you, "no.. no, not really."

it's sweet, he thinks, the way you make it sound as if there's just not anyone that took an interest in you. as if you didn't act as a magnet to the hungry gazes of men all around, whether it be at your campus, the stadium as you go and pick him up from practice, or simply at the street when you both take a stroll. as if he didn't have to stare them down, a glare so cool and threatening there usually wasn't a need to even open his mouth and snarl.

"eh, that's good i guess. you should be focusing on keeping up the scholarship, anyway." your father chimes in as he brings the glass up to his mouth and sips.

yeah, you think, and just coincidentally, rin happens to wonder the same. there's no need for anyone. no one but him.

there's a gentle screech of your chair sliding across the hardwood floor as rin reaches under your seat and pulls you to his side. you jolt at the action, slight laughter bouncing off the table. even sae's looking at you with an entertained kind of stare as rin reaches a hand up to ruffle your hair.

it's playful, but still so gentle - just barely affectionate, in a way that only you can recognize. it makes your cheeks heat up, gaze bashfully moving to the side.

"no worries. i'll make sure no dirtbag keeps that head busy." rin quips, a ghost of a smile on his lips and it earns him a few chuckles and affirmations from your parents.

of course he will, if there's ever any fool delirious enough to try and shoot his shot and sweep you off your feet. but despite his possessiveness and borderline territorial nature, there shall never be no need for that - simply because you'll never, ever have eyes for anyone else but your nii-chan.

just when you're about to tilt your head to glance at the ravenette, there's an all too familiar feeling of a warm, large palm settling on your thigh comfortably - high enough to let the pinky finger tease at your groin, barely an inch away from your panties.

it's more than enough to render your body putty, frame stiffening and eyes drooping slightly as the first thing they search for is sae.

he's always been anything but dumb, sharp eyes observing everything around and able to make out every tiniest detail, whether it be someone's position on the field or the slightest expression on somebody's face. what's worse, he never hesitated to point it out - voice it loud and clear whenever something was about to go off the rails or it has already irritated him.

but this time, as your eyes lock, there's just the usual bored look written on his stupidly handsome features, and he even lifts his brows in a silent question, what?

you shake your head a bit with a shrug, shifting in your seat as you break the eye contact - but rin must misinterpret the movement as an attempt of getaway. that's what you think with the way his fingers dig into the soft flesh of your upper thigh, then slide further to the side, ring finger now teasing at your core.

a breath hitches in your throat when you finally steal a glance to your stepbrother - and you're dumbfounded to find he's not even looking anywhere in your direction. what's worse, he even picks up a conversation with your mom, probably some sort of stupid small talk that he's capable of carrying only with a few people - that being your closest family and yourself. you can faintly make out that it's something about the recent transfer offer that rin got from no other club than real madrid itself.

there's a sort of desperate look in your eyes, there must be, as you feel the pad of his finger slip past the soft silk of your thong and dip between your folds, where moist already collects.

"did i accept?" rin echoes, repeats your mother's question in fake consideration, "hm, not really. they didn't offer me anywhere near what i'm looking for." rin hums and it breaks you out of the spell he cast on you with his feather light, but oh so teasing touches. you glance back to your mom, and the glob of saliva gets stuck in your throat as rin's finger grazes along your clit - more forcefully this time, rubbing an agonizingly slow and tight circle on the nub. "they having some finance issues, sae?"

please, please don't - it sounds out so desperately in your mind, you wish, pray that rin hears it as he purposefully brings your older brother's attention to him - to you, sitting within an arms reach next to him, probably looking like you've just seen a ghost. or, like you've just ran a marathon - you can't really tell, cause the slow but firm pace that rin moves his fingers at makes your body tremble with waves of both heat and ice cold sweat.

even as you hold sae's stare, just as unbothered as always, from the corner of your eye you can see rin's jaw slack and eyes darken.

you watch the redhead lean back in his seat, fingers mindlessly drumming on the edge of the table. "huh? what're ya talking about?" he's taunting him, and god you know it's no good news. "they sent you an offer or something? sorry, rin, but that mustn't be any big news back there 'cause i've never even heard of it."

his voice is monotone yet soft, and just as always, your parents seem to be oblivious to the sharp blow that sae's hidden behind the words, because they don't even bat an eye - instead, you can faintly hear them mumble something to each other, busy in their own conversation.

you bite back a yelp as rin's fingers only seem to press down on your throbbing clit even harder as he leans back as well, as if to further expand the distance between him and the older itoshi, "maybe you would've, if you didn't have your head up your ass all the time, yeah?"

there's an annoyed lilt to rin's tone and as much as you'd usually worry over his temper being toyed with, the sound only makes even more juices ooze out, caught by rin's middle finger as he dips it to prod at your fluttering hole.

"nii chan, stop-"

you breathe out, the frustration - desperation - so pronounced in your voice, you miss the way sae smirks at the sound. he's so fucking oblivious, it makes rin want to smack the amused expression right of his face. he could bet his all that he has no slightest idea that you, begging so sweetly, had anything to do with him having you creaming on his fingers - and very little to do with the fact that your older brothers were fighting, as always.

but oh god, if that doesn't make his cock even harder in his pants, then he's delusional.

"see, stop bitching. you know she doesn't like it." sae cuts the thick tension with a knife, and moves his eyes to you, where you sit so weirdly stiff, eyes moist and bottom lip caught between your teeth, almost drawing blood.

in all honesty, you don't know which makes your mind reel more - the sensation and pleasure itself, or the sheer obscenity of the act and how it feels lewder than anything else your brother has ever done to you before.

cause there's been plenty of disgusting things he's made you do - starting from the way he'd have you send short, but oh, so filthy videos of yourself, showing the wetness pool in your little underwear, manicured nails pushing the flimsy material aside to reveal the sheen clinging to your cunt. m'being good, nii-chan, promise, you'd whimper, needy and breathy as you can already imagine what he's about to do as soon as he gets your text. the scenario would play out every time he had to leave for an away game, pressing a kiss to your temple as you dropped him off at the airport. due to the early hour, there's barely any people around at the gate, and so he allows himself the smidge of affection your way. you're gonna be a good girl for me, right, love? show me how well behaved you are? you'd only nod softly, hands cupping his cheeks as he leans down to give you a chaste kiss. f'course, rin nii. always.

but that was only the very tip of the iceberg - and you know it. and yet, rin stuffing you full of his fingers, prodding at all the spots that would usually make you mewl and cry out - all while getting purposely riled up over his brother's usual ignorance - might just take the crown.

you know he's insane, there was never a doubt about it from the very first time he's had you spread out for him, the zoned out look in his eyes making you shiver. it was so familiar - he was your stepbrother after all, the one you've grown up with, attached by the hip - and yet nothing like him at the same time, as if a switch flipped. you can recall it was right after he came home from the final u20 world cup game japan has played out. he has just turned nineteen and you've came to the game dressed in his jersey, with his name on your back, and yet, with some another fucking sleazy guy standing next to you on the bleachers. as if to taunt him. tease him, make his blood boil even further.

you're mine, you can still remember the way he groaned it against your lips, made you cry with the way he bullied himself right inside of you. you hear me? you're all fucking mine, you know y'are. bet he didn't feel anything like it. if you by now weren't sure about rin, your sweetest nii-chan, the best big brother you could've ever wished for being your one and only love, then at that point, you vaguely recall all restraints breaking. i love you, nii chan. please- ngh- please, rin, love y'so much. m'all yours, promise, no one elses, rinnie.

yeah. he's fucking insane, unhinged and out of his mind when it comes to you - you've known it all this time. so why are you so dumbfounded, nearly trembling with both arousal and anxiety as he shamelessly, deliberately pushes himself further into the spiral of exasperation - all to bring you over the edge?

rin slips both his middle and ring finger inside your cunt with ease, all the way to the last knuckle and it almost knocks the breath out of you. but you're so, so focused on keeping a straight face - hands gripping on the skirt of your dress until they turn white. he's treating you so good, after all, and you're expected to be on your best behavior when he's giving you so much. you were always his good girl, after all. you're not about to disappoint him, especially now, right?

he curls his fingers about two, maybe three inches in, presses them right against the front wall of your pussy - massages at the spot that'd have your knees give out if you were standing upright. his palm steadily, firmly rubs at your aching clit, swollen from all the attention he's been giving it, and you can feel the all too familiar tension grow tighter in your lower tummy. it makes your cheeks heat up, high heel clad foot involuntarily kicking out under the table.

it misses sae's leg by just a few inches, but he doesn't notice.

your lashes flutter as you fight your eyes to stay open and alert, thighs unwittingly squeezing together until the point rin can barely move his wrist anymore - at least, in a way that'd leave his bicep stuck in place, unmoving, and not giving out any of the things that were happening just barely under the table. he exhales sharply, half from annoyance at sae's attitude and half because of you making it harder for him to bring you to your climax.

he gives you a side look, teal eyes blown and hazed - a look that you know all too well. a silent permission, and a chance to swallow up all the prettiest looks you're giving him.

he drinks up your expression, utterly fucked out under the mask you've put on for the sake of keeping your parents and sae sane and sleeping soundly at night. but he can tell, he knows you're close not only from the way your walls start to throb around his fingers as they reach deeper with each movement. he sees it in the way the tears cling to your lashline, barely visible and a glass sheen over your bright eyes - recognizes it in the way your throat bobs, teeth gnaw at your plump lip with utter desperation.

his gaze softens, just momentarily, and his heart swells as how good you're being for him.

his good little girl. always.

"as if you knew." rin's voice drops, carnal and thick, and he spares his older brother just a languid glance. "you're not around anymore, aren't you?" your breath catches in your throat, chest growing tight as you try your hardest not to slip a single sound out. rin's fingers move even deeper, harder, even more precise. you can almost feel it snap, feel the warmth wash over, cunt almost squeezing his fingers-

"can't see how good your little sister is."

there's a shaky, harsh exhale that makes your lungs burn and eyes water even further; your thighs turn to jelly and twitch on your seat and around rin's hand once or twice as you come. it hits you harder than you supposed, leaves you squirming slightly in your seat and god, you're so, so embarrassed. you feel so used, all for your dirty big brother's pleasure and fucked up fantasy, but yet, the pleasure clouds your mind and leaves you breathless, unable to care - or yet alone notice - whether anyone, especially sae, has noticed anything off about your behavior.

you can feel rin's pent up. you can scent it on him, the heat radiating off his body and the need that seeps out every pore of his skin, amping up the woody and sharp scent of his ridiculously pricey cologne - making you quiver for him even more, blood thick with desire.

you force yourself to relax, all too early than you would've liked, and let yourself slump in your seat slightly. rin takes it as a sign, feels the way your cunt allows him to ease his fingers out, slowly and gently - a sharp, mocking contrast to the downright brutal treatment he's given you barely seconds before.

you wipe at your eyes, a shaky hand reaching up, and you can only pray that sae remembers how easy it was to make you break down into tears. the way you'd scream at them to just fucking drop it, a wobble to your chin as you rubbed the tears away quickly - a scene that'd act out during each and every one of sae's visits back home after the incident.

there's many things your stepbrothers share, no matter how much they try to deny it. their passion for soccer; a set of mesmerizing aqua eyes hiding behind thick lashes; a strong build, despite a difference to the broad of their shoulders and height; and finally, their observant nature.

therefore, it's only natural that of course he remembers.

but then again, realization washes over you, like a wall of cold water that renders all your senses alert and screeching. he's always been attentive, both him and rin - since the youngest days. he chuckles slightly at the sight of you wiping at his eyes, hopefully mistaking the action as you just being a crybaby as always, and your mind starts to spiral with the fear of him seeing through your little act.

he's ridiculously smart, always has been, so it would make perfect sense for him to pick up on what has truly just happened.

the sniffle that you let out isn't even the slightest bit forced, not with the way your anxiety spikes. sae knits his brows in a kind of diverted expression, eyes still glinting with amusement and seemingly missing the way rin wipes his fingers on his pants in silence.

"awe. still getting so worked up over that, sis?" he's taunting you, but it's nowhere as harsh as when he does it to rin - in fact, if your mind wasn't so full of panic and reeling with shame, you'd maybe pick up on the hint of affection in his voice. "you cannot be like that to her, rin. seriously. you like making her cry or something?"

you squeeze your eyes shut behind your palm, deep breath filling your lungs with air that feels like nothing but filth, an aftermath of what you've done. of what rin made you do - that's what your conscience wants you to think - but your shoulders slump in defeat when you admit it to yourself. you like it. or, what's even worse - you're the one that's making him this way.

the thought alone makes a shiver crawl down your spine, licking at your skin and leaving behind a trail of shame.

you finally muster up the will and courage to look at sae - give him a wet look that makes his eyes grow strangely foggy. the eye contact must be way too long for rin's liking, though, as he once again rests his hand on your thigh - but this time, his touch feels warm and comforting, soothing your tired muscle and deteriorating mind.

your head turns and tilts slightly, tired gaze searching for his - but he's looking right ahead, holding sae's stare with a smile that looks far more unhinged and risky than you'd have liked it.

satisfied, you realize. as if he won.

(what was the stake?)

"what the hell?" he retorts, annoyed.

now, rin itoshi is many things.

he's the prodigy's younger brother, japan's national team captain, basking in the afterglow of reaching the very top - being declared as japan's top scorer, most efficient striker, the one who brought the country to first ever victory.

he's your big brother, the first person to ever gain your full trust and unconditional love. your first serious boyfriend and your only lover forever. he's the one that would risk it all for you, if it only meant seeing the smile on your lips that make his knees - the very same ones that can carry him through the whole field - buckle with affection.

he's deranged - and he knows that. he feels it when he has you folded over, hamstrings pressed to his chest and hands wrapped around your throat, forcing the prettiest moans and truest promises from your mouth. he feels it when his mouth further salivates seconds after spitting right down your awaiting tongue, staining you with his filth.

he feels it when he can barely keep himself up, cock twitching and bullying your cervix as he cums with a groan upon the sight of you crying - eyes wide and yet, so full of nothing but adoration, mouth parted in a moan of his name, and cheeks wet with streaks of hot, salty tears.

"you know i don't."

rin is many things - and he decided he might as well be a liar.
