dear reader ! i am excited to share this! rin + this trope had hogged my mind so well... disclaimer ! i have no experience in writing smut and english is not my first language. the food idea was from a convo with grayy (thankyou), biggest thanks to renaa the supportt grr ily <33 and TORII! ( @twitoshi ) baby so grateful to have thoughts from youu!! ilysm !! #BESTBETAEVER.AAH KISSINGYOU SO HARD RN T^T

The hot water ran down your back, draining away the soreness of the busy day. It was later than usual, and you did wait long for Rin before intruding his bathroom for a late night shower. It came to this, all because the showerhead in your room was broken. So, after an hour long you just invited yourself into his room.

His room was so devoid of things, it felt colder than before with his presence gone for so long, unlike Sae’s. But it was only that way thanks to you taking out the time to decorate and buy pieces for the apartment. So, when Rin started staying over, you set one for him.

“When you get a girlfriend, she can decorate this place all she wants…” You had joked hinting he could move in, when you took him out shopping. “I do not plan to date anytime soon.”

Ever since you met Rin at the family dinner, you adored him, instantly. You had always longed for a perfect family, and he seemed to fit so well. Since then you made it a point to visit him with treats and new movies to talk about, inviting him over for dinners whenever you got a chance, which were usually turned down. Yet you were so driven to keep him around, it didn’t matter. Being aware of how things went down between the two brothers, you were careful to not step on any toes, but still looking out for Rin always and making sure he felt welcomed to spend time with you and Sae.

“I don't mean to pressure you Rinnie-” Rinnie, he frowned at the nickname making you correct yourself in an instant. He didn't consider you close enough to be giving him nicknames yet it felt oddly comforting the way his name rolled off your tongue, a sense of affection he didn't realise you dug in him. “Rin- I mean... I don't mean to overstep between you brothers, but I’m always here if you want to get things off your chest or just a friend. Consider me your nee-san Rinnie…” You smiled sweetly at him, tenderly cupping his cheek. The warm affection of your kind nature disgusted him, but you shrugged off lovingly. It went over a few times, until he got around to calling you that. Nee-san. And he was your Rinnie from the start.

Sae, for a matter of fact, wasn't dismissive of Rin's presence. He even offered to let him stay over if he wished to. The first time Rin accepted the invite, he barely slept at all. The walls weren’t thin, but you were so goddamn loud—every sound and moan reaching him despite the concrete. Hoping it would pass, he put on some music. But, even that failed to drown your whines. He considered leaving or at least knocking on both of your doors, but the soft, lewd moans seeping through the walls invaded his mind uncontrollably. It was obscene to picture you but he didn't fight it. The depths of his heart, twisting shamelessly into what was the tip of his infernal yearnings. Every stolen glance, every touch in the shadows, sowed into an unaware desire. Giving in to your angelic voice, laced with sultry undertone that rang in his ears, making every minute feel like torture. The line of right or wrong blurred so easily. It poisoned him. It was repulsive how despite his better judgement, you coaxed him to pull down his boxers.

The next morning could’ve been better had you not walked out in one of Sae's tanks, barely covering anything, tying your hair up, your face puffed, as you approached the kitchen station. “Fuck” You shrieked, finding him in your kitchen. Did you not remember he stayed over?

“Sorry, Rinnie,” you said, sitting by the station, leaning over the island lazily. “Sae and I got around to drinking a little. He is off practice this week, we-we got a little carried away…” Your voice was sheepish, falling into a chuckle as the memories of last night replayed fresh. You blushed drifting off.

“What you doing baby?” Baby, you never gave it a rest did you? Your chest displayed purple marks from the night before as you hunched over. Rin couldn't help but steal a few glances down at your body. Glowing despite your hungover and the messily tied up hair. It was perfect, accentuating your exposed neck. His eyes drawn to the sight of you, as you arched and stretched with half lidded sleepy eyes. He ogled at your pebbling nipples poking through the white tee, so perked and tightening by your sides as the tee somehow managed to concede it. Last night, he palmed himself to your whimpers, and the way you sat right now was inviting for something more. The idea of fancying you was alone be loathing, yet the more he hated, the more eagerly he stripped you naked in his head.

“Baby...” Sae’s morning voice followed from behind making Rin immediately look away. Whatever you did, had his nii-chan wrapped around your finger. Sae squished your face roughly up to meet his, pulling you into a hasty kiss. He held you so recklessly, with no manner or care, Rin watched his brother manhandle you from the corner of eye. The redhead’s lips linger on your mouth, as you sneak a taste in between, sticking your tongue out wide for him to play on. His fingers traced your neck as you gulped, you didn’t care how he touched you in front of another; if anything, you fed into his ego. You mumbled sweet nothings teasingly as you wished him a good morning, your eyes twinkling with mischief. It was as if you revelled in the attention, the subtle touches, and the way it made him feel. Rin’s gaze followed your tongue, licking the corners of your mouth, the crunch of your subtle bites aimed for Sae and Sae alone. The inconsiderate touches, sickened Rin, toying with him like a puppet. Even when Sae pulled away, finally acknowledging Rin, you pressed yourself against his stomach softly. His hands roamed confidently across your chin all through your neck, as though mocking his younger brother. You seemed to enjoy the raw affection of your lover. The rough demanding touches, building fantasies of how you liked it.

“Slept well?” Sae snapped, shattering the thoughts that had been swirling in Rin’s mind as if they were loud enough to be heard by his older brother. A cold shiver ran down his back upon hearing Sae’s voice. It made him feel fifteen again—weak, naive, his confidence crushed in an instant. He hated the feeling rising in his chest, making it hard to swallow. Did nii-chan know? No, that would be silly. His eyes remained fixed on the floor.

“Be nice, Sae!” you whispered softly, wasn't this unbearable enough that you were rushing to his defence.

“I slept fine,” Rin lied, his voice barely more than a murmur.

“Okay, stay for brunch,” Sae hummed, his attempt at being nice, then shifted his attention, “and you…” Just two words from Sae had you standing instantly, leaving Rin feeling utterly invisible.

Rin clenched his fists, heart pounding as he slowly realised he was becoming a prisoner of his own thoughts of you. The way Sae held you, the way you kissed Sae with such fervour—it filled him with both longing and frustration. The more his brother possessed you, the more Rin ached to hold you in the same way, to make you his. He convinced himself he could treat you better than Sae ever would, love you more than you could imagine.

Rin started crashing over more often, always around whenever Sae was away. You had found a friend to keep you company, but for Rin, your presence plagued him. He couldn’t escape the sight of you, You began showing up at his practices after work whenever you could, and it only made things worse—or maybe better. He couldn't decide. The wardrobe choices set him into a spiral. The cute low-cut floral dresses, hugging your body a little too tight had him wiping his drool between the game. Every time he scored you cheered praising him from the benches. You paid attention to his play, unwavering. He hated the looks his teammates passed at you. You were his Nee-chan, only he possessed the right to look at you, though insane, it was perfectly rationalised to him.

Despite his ignorant pretending—your doe-like eyes and the softness in your voice that only served to annoy him further. Sometimes, pushing it too far, babying him in front of everyone. He knew deep down you meant well, however this show of affection deeply fumed his annoyance— Yet, he indulged in it every minute around you. The way you were so small in his comparison, wrapping your arms around his large frame—he practically towered over you—tip-toeing in your high heels, to shuffle his hair for his performance. Always looking up to him, eyebrows raised, shimmery eyes, as you blinked dreamily, you were clawing your way under his skin, it was nauseating to picture how pretty you’d be under him. Beneath his sneer and frustration, there was an undeniable craving for the attention you lavished on him.

He found himself groaning alone, devoid of you, setting a rhythm to his jerks. Mind left to run wild, a devil’s spawn. He desired the intimacy of your touches right now. Your hands, so much smaller and softer than his own, your wide beautiful innocent eyes fluttering with tears as you’d take him in your mouth. The image of your red lips latching onto his cock, would it fit? He’d make it fit. Losing his mind to have you on your knees, tits bouncing as he’d push his length down further. The mouth that kissed him with words, he would fuck it so well. Make you so cock drunk on him, until you're begging for more, intoxicated by his veins. Did you enjoy playing these sick mind games with him? Being so careless, bumping into him on purpose, making him catch you by the waist. Did you like to sweep your hands as an excuse to stand straight every time you stumbled. Did you pretend to fall asleep when you both watched movies, tugging tightly onto his shirt? But he held back. He held back when he would put you in your bed. When he could smell himself on you in the morning. He would love you better, fuck you harder than his nii-chan could ever, if you ever open yourself to him... Did you see him the way he saw you? Numbing his sense of awareness, until it all disappeared into nothing but you. You, your scent, your being consuming him every second. Rin’s head fell back to the cold water running down. “Nee-san” he moaned, cursing you. He would ruin you in unimaginable ways, nestle in your mouth, make you swallow him as whole, will you do that for him? Your mouth filled with him, gloss smeared in his cum. He practically drooled again, head thrown back, the faster his hand rutted the clearer his visions got. The hate that disappeared in between slipped back once the translucent fluid messed about his hand. Fucking disgusting nee-san.

“You took so long Rinnie…” You pouted worrisomely, “Did something happen?” The thought alone had him softening for you. Again. It was the same face you made whenever Sae’s flights got delayed. It irked him. It took all of him to not sneer and tell you it was your fault. Why did you show up in these skimpy clothes? “It was nothing nee-san” Instead he brushed off, with a frown. No matter how hard Rin lied at the end of the day, it was you who he found himself running back to. Just one last time he told himself before he gave into it every single night.

“Rinnie, taste this” you put your hand holding his favourite sauce, “I've been trying to get this right... Tell me if you like it” You were overbearing to him. The more around you were, the more frustrating it got for him at times. Always intruding with a yearning gaze, a full curve smile, having you around was bad for him he knew. But not being around you was far worse for him. Miserable, it felt miserable to have his pants strained at mere gestures of you, to not be the one to kiss you all the places you touched yourself thinking of his brother. You did everything with him, but fucked his brother. Were you so unaware of what effect you had on him?

His brows furrowed, tasting the sweetness off your finger, it wasn't intentional but his tongue swept off a little further. You didn't flinch at all. “You like it?” There it was again. “Hmm...” He only grumbled, but his eyes widened for what you did next. Rin hung to your every moment as you licked your finger back, savouring the sweet sour taste of the sauce. “It is good!” Wasn’t it enough he woke up in the middle of the night to your moans and whimpers, deranging him of reality, that you put new images in his head.

“Do you think Sae will like it?”

There it was—the fracture in his perfect illusion. Sae. Always Sae. Each time Rin felt a thread of closeness with you, his brother’s name would slip from your lips, ripping Rin’s carefully woven fantasy apart. Rin blamed Sae. How could you—so pure, so innocent—see anything in a man like him? Sae wasn’t there to hold you when you twisted in your bed, buried in pillows restless and aching for him. All while he laid awake in the dead of night, waiting for your breathing to slow, your voice to whisper softly in your sleep. Rin, learnt your patterns. He saw the way you tossed and turned, your body subconsciously reaching out for something that wasn’t there. And it enraged him—Sae wasn’t even here, so coudln’t you shake him off your mind.

Rin turned over in bed, teeth gritted as he clutched your panties—so conveniently forgotten—held tight in his fist. Your scent overwhelmed his senses, lacing his thoughts with heat that crawled under his skin. He breathed deep into the fabric, inhaling every little bit of you, eyes closed, imagining your touch on his skin, your soft moans filling his ears. His hand moved faster, body drowned in need, but then it came—his name, spilling from your lips even in your sleep. A cruel reminder of the barrier that always stood between him and you.

The night your phone rang, you were still blissfully unaware, passed out from drinking too much, lost in your oblivious dreams. Rin glanced at your phone—Sae <3. His brother’s name flashed on the screen. A tightness in his throat knotting him, knowing Sae didn’t deserve the glimpse into your life that Rin guarded so fiercely.

Sae’s raised eyebrow surprised to see his brother. "Where is she?"

Rin swallowed thickly, his voice struggling to stay steady. “She’s asleep—”

But before he could finish, you stirred, murmuring that cursed name even in your haze of sleep. "Sae?"

A flash of something dark surged in Rin. You were in his bed, surrounded by his warmth, while your mind still lingered on his brother.

The decision snapped in his mind—he couldn’t keep living like this. He had to have you, fully, irrevocably. But fear clenched his gut. You loved Sae, that was undeniable, but he knew you felt something for him, too. You couldn’t fake the moments when your gaze lingered too long, when you called him your sweet "Rinnie" with a tenderness that drove him insane.

In some world, it could have been enough, but right now it wasn’t. He wanted more. He wanted everything.

So, Rin pulled back. He needed you to want him, need him, in the same consuming way he needed you. It was a sick game, and he was prepared to play it. If you couldn’t give him what he wanted, then he’d make you see it. No more nights spent in your bed, no more tender moments when you fell asleep in his arms. It was excruciating.You missed him, but he articulated his excuse so well you believed him without doubt. Drowning in self loathe, he hated lying to you.

But tonight, he promised to come back. You had wanted to cook for him, but work ended so late, and now you were hoping Rin would bring something to eat.

His phone rang thrice, your name screened, before he muted it. He had made promises to you, sure, but those felt distant, half-forgotten. He wanted to keep his little chase up, but she made him feel more than a man he had ever felt with you. She did not weigh down his insecurities, always being second best; She was more composed than you could ever be. She was prettier, better than you, and kissed him, so why did his mind wander off to your cherry lips, digging in his subconsciousness he tried to deny. You were the one he slept next to. Deaf to her voice, pulsating to your memories. Every step away from you only brought him closer.

The date ended not too late. When he checked his phone again, the screen read 11:23. Five missed calls. Four unread texts.

06:33 PM: Rinnie, have some last minute work, might be an hour or two late. Sorry to cancel dinner tonite :(((

07:54 PM: Can you get takeout if you’re still coming over? I will be home by 10.

10:24 PM: If you’re not coming it’s fine… I’m just worried about you…

10:25 PM: I hope you're safe, baby.

He would’ve ignored you the way it was going, make you work for it like he had planned it out, but upon dialling back when you did not pick up, He felt the surge of urgency to see you for himself. He should be driving back with his girlfriend, but he wasn’t. The little facade breaking down, he was never going to win. So depraved of you since these past days, he couldn't hold back. You made him so weak. Had he left you alone for too long? He could taste the guilt, bitter in his throat. Fuck. Knowing that the one time you asked for him—needed him—he had failed you. Why didn’t you just give him a reason to hate you?

“Nee-san...” His voice broke through the thick silence as he dialled for delivery, pacing, the sound of running water echoing from the bathroom. You hadn’t expected him to come at all, not after the cold silence between you. He heard the water stop, then your voice, soft and distant. “Rinnie, I’m in here,” you called from his room.

His breath hitched. You were in his room. His pulse raced as he stepped closer, mouth dry when he saw you emerge, a towel wrapped loosely around your body.

“The shower head was broken, sorry for intruding… I’ll get it fixed.” you explained, a little embarrassed at the scene. You sounded distant. Did he make you feel that way now? Did his presence not comfort you anymore? Why did you have to apologise like that? Were you upset that he was gone? Did he just fuck up everything by not thinking this through?

His eyes travelled down your wet body, God he missed your reckless ways in which you moved, the light in your eyes that had once pulled him in like gravity. He missed you, but this time around you had missed him equally, or more. “I thought you weren't showing up? You barely come over anymore” You shuffled around picking your things walking around him as he stood like a statue, a strange feeling he couldn't stomach.

“Uh- I was with a friend-”

“Oh.” Oh? You didn’t ask for details, didn’t tease him the way you always did. Just that one word—so cold, so unlike you. The silence suffocated him as he watched you walk out of the room, he followed. He felt uneasy with this feeling festering in his chest. Afterall he meant for all this to happen, but the hostility was maddening.

“Umm-”

You put your clothes in the laundry and he stuttered to find his words, laying out your night pyjamas, “Did you forget something?” You spoke so plainly it hurt his cavity. “Umm.. dinner.. I ordered dinner, creamy cheese pasta and pesto sauce.. you like that nee-san” desperate for a sign that you still cared.

You sighed, barely a whisper, “I-” the way his eyes changed, the hindrance of guilt covering his face. “... I can't say no to that but first I need to change…” You stretched the curtain on his face. He turned around. Curiosity getting the better of him, he heard the soft rustle of fabric, the faint thud of your towel hitting the floor. His mind raced, his body tense, picturing you there, so close yet so far.. “Did you not get my texts Rinnie..?”

Moment of truth? He never wanted you to learn about her, He knew what he should say. He knew how easy it would be to lie, to smooth over this mess. Still, his tongue caught between confession and deceit.

“Don’t lie to me baby”

“I- I was on a date..” He blurted.

You froze, the air between you thickening. You pushed the curtain aside, your expression a mix of disbelief and something darker—something that sent a chill down his spine. “A date?” Rin with a girlfriend didn't quite sit easy with you. It was rather strange and out of character from what you've come to know about him.

He shifted uncomfortably under your gaze, rubbing the back of his neck, eyes darting away. “Yeah. It... it was nothing.”

“Nothing?” you echoed, disbelief tinged with something sharp. You stared at him, waiting for more, waiting for something that made sense. Because this wasn’t like Rin.

Rin felt trapped under the weight of your eyes. “I didn’t— It just... happened.” His voice cracked at the end, frustration lacing every word. “I thought... I thought maybe I could forget for a while.” He was inaudible but you heard him.

“Forget what?” you asked, voice quieter now.

Forget you.

“Nothing.”

—

You busied yourself in the kitchen, the dinner had to be nothing less than perfect. Rin had always been more reserved, keeping to himself, but tonight felt different. He finally planned a dinner at your place with his girlfriend, and though you couldn't quite pinpoint why, there was something about it that made you feel uneasy. And god forbid if you could read his mind. You didn’t understand why he had been so hesitant—he always dodged the topic when you asked, giving vague answers, as if he wasn’t ready to fully admit she existed. From the little he told you, she seemed lovely, but each time he mentioned her, a knot twisted in your stomach. It didn’t make sense, not until tonight, when you finally met her.

The devil lied in the details, it was subtle swatches across his shoulder, the they she caressed his face, licking the corner of her mouth. How she pushed her hair back, her eyes motioning slowly for Rin, the sparkle of joy. The realisation crept in slowly, the way she styled herself, the way she moved... It was like looking in a mirror, a distorted version of yourself. It wasn't blatantly obvious, but you read her like a book. Both of your reactions to Rin were almost mirroring. Almost as if a hastily built clone with no care. It couldn't be, it was a pure coincidence. Rin’s hand rested possessively on her waist as they stood together, his fingers clutching tightly around her. It looked strange—wrong, even. Your baby was flying from the nest, and this was just jitters, you just wanted the best for him. And who but you knew what was best for him.

You glanced at the clock, feeling the heaviness in your chest grow as you placed the crockery out. You stared at nothing in particular, lost in your thoughts, the clinking of dishes becoming mechanical. “Nee san?” Rin called out breaking through your wall. He stood tall behind you, his body casting a shadow as he towered you catching the sipping plate. His brows furrowed, concerned. You blinked, realising you had been staring directly at him, yet completely lost in your own mind. Past weeks, even though he put an effort to be around, you had been pulling away no matter how hard he tried, a failed attempt each time. You stopped coming for his practices all together. No shopping, maybe he was overthinking, what if it was just a misunderstanding and you were mad at his brother? It edged him every passing day. The distance was unbearable, like a punishment he couldn’t understand, He was the same boy? Did getting a girlfriend bothered you so much, but you were so sincere around him. Then, why won’t you just hold him like before? It was cruel even for you to treat him this way. And tonight bothered you beyond resolute.

“Are you... okay?” Rin’s voice was tight, his eyes traced the way you fidgeted with the red strings tied around your dress, your gaze shifting to anything but him.

“I’m fine” You say faintly, losing focus again as you stumble, reaching out to the stone slab. Rin instinctively caught you by the sides. His large hands swiftly slipped down. It wasn't something he had ever planned to do, but the moment called for it. He had held back for so long, always looking in from shadows, but right now you were pressed against his torso, your dress slid up from the friction. Drunk from your tired, heavy gaze, he felt losing control of it. Your perfume filled him to the brim.

“What’s going on with you?” He snapped clenching his jaw, his frustration getting the better of him. You shuddered at the raised voice, making him instantly regret it, squirmed a little in his brace, but his grip untouched.

“You’ve changed…”

The words fell short in his mouth, you assumed he'd break away to let you slip, but his fists tightened, riding your dress higher.

“Rin... What are you-” You breathed heavily. The sound of his name on your lips was his undoing. The last straw, when you were so fragile at his bay. His dick throbbed as your bodies pressed on tighter, leaving no space in between. Longing fingers, motioned hesitantly, searching their way around your thighs.

“Changed? Huh?” He growled, pressing on further, “Why? Because I don’t let you cling to me anymore? Because I’m tired of being second best to him?” His words came out in a rush, his breath hot and vexed as he tried to make sense of the storm raging inside. How easy for you to tell him he changed. He didn’t know whether to hate you or fall apart in your hands or to remind you he was the same man. Regardless of how much he fought it, he couldn't pull away. You were too close, too tempting, and every second you spent in his grasp only fed his conflicting emotions.

You smiled faintly, brushing your fingers lightly across his chest. "Is that what you think? That you're second best?" Your voice was dipped in honey. “Is that why she is sitting outside?... Is that why you stopped coming home, to me?” glassed eyes pierced his teal one. Rin hated how easily you got under his skin, how simply you twisted his emotions until he couldn’t think straight. But even as he tried to maintain his stand, he felt himself crumbling at you breaking down.

His fingers brushed against the dampness of your arousal, and you didn’t pull away. Instead, you moaned softly, shutting your eyes helplessly leaning into him. The sound sent electricity straight through him. Your hands reached up, clutching at his turtleneck, pulling him down to meet your gaze. “You hurt me like that Rinnie” Your doe eyes still held their innocence, but the predator in you was clear as day, making him kneel. Wicked. He was going to make up for all the shit he had put you through, correction, the mess you deluded him he put you through. Rin lifted the scarlet hem, to find the black laced panties sticking wet. His date was the last thing on his mind. Even if the world were ending, it wouldn’t have mattered. He needed you first—needed you more than anything else. Without hesitation, he pushed your panties to the side and latched his tongue onto your wetness, desperate to taste you.

You were perfect, gorgeous the way your pussy split open to his tongue, it was a sight he never in a million wild dreams could have imagined. You felt the cool aire being replaced by his spit. Tongue roughly sweeping across your slit. His sharp moves drew out lewd noises, “Slo-ah-ahw dah-own” you squirmed as your legs started closing in from the rough pace. Rin didn't want to savour any taste, all he needed was to relinquish his thirst for you for months now, empowering all his other senses. The heat radiating from your core, your peachy lips parted in pleasure—it turned him into a monster, one you had created. “Fuck, just cum on my tongue” Rin sloppily spoke, breaking in between kissing your sweetness. The wet smacking sound filled the space, as he blew into your cunt making you cm messily. The milky fluid he lapped, pushing his tongue inside, as your body twitched on him. It wasn’t enough, you rushed this one. Start over.

He pushed one of your legs over his shoulder, letting your weight rest on him. Every flick of his tongue, a desperate attempt to hear you moan his name once. And when you bit your lips, eating up your pleasure, it only made him more feral, more determined to claim you. His pace quickened, your fingers tangling in his teal locks, stroking in and out in reach of something sturdy.

You squirmed over his face. Your sweet core was so welcoming, he could stay like this for hours—devouring you, making you cum over and over until you were nothing but a trembling, blissed-out mess. He groaned against your sensitive skin, sucking on your swollen lips, gripping them between his teeth with just enough pressure to make you cry out. Every sound you made drove him further into madness, desperate to keep you on the edge, completely lost to the sensation of his mouth on you.

“Did you miss me so m-much-uh.. I thought yuh- didn-t mpph- like your nee-san a-anymore” You moaned, pushing yourself into his face shamelessly.Your head threw back surrendering to the overwhelming pleasure he brought on. It was a blissful sight. He resented himself as staying away from you, but instead of words he just wanted to show you.

Rin was merciless, curling his slender fingers inside you, with no rhythm or restraint, just pure starvation to break you on his hand. He didn’t care for setting a pace, his thrusts were wild and desperate, matching the chaos in his mind.The dining room way away thankfully, but part of him liked the thrill that his date could walk in at any moment, finding him knuckles deep in you. Hell, he needed his nii chan to walk the sight of you pleading him to go faster.

He abruptly stood up, slamming you against the fridge. It was hot even for him to be so aggressive around you. Rin, blushed seeing how much you liked it. The way your body reacted, sliding into orgasm, your knees growing weak, he had been edging you for so long. “Look at me nee-san” Bitterness coated the words that dripped out of his mouth, while you struggled to keep your eyes open, as they fluttered shut with each curl of his fingers, coursing through your pleasure. Saturated on his tongue and now fingers, you whimpered, clawing his sweater.

Even when vulnerable, you were in control, you somehow still held him on a leash. Him, nothing more than a guard dog abiding by your play. He would, he would do it in a heartbeat for you. Your tightness sucked him whole but it wasn't enough, you needed more. “More Rinnie” You didn't care for the guest. You didn’t care about anything but this, so loud, peppering with ghost kisses all over his lips. His thumb ran circles on your neglected clit, pushing another finger inside.Your breath hitched, nearing your close, rutting your skin on his hand, chasing that peak.

Rin lost to the sight of your body jolting and twitching as you came on his fingers. Trembling from your orgasm you rode your high, and he held you. You deeply breathed and he pulled his fingers out intended to make you taste yourself but you got him first, smiling innocently, getting him to suck his own fingers lapped in your cum.

Then, with a soft, teasing smile, you pulled your panties down, stepping out of them before pausing. Your eyes flicked down to his painfully hard length pressing against his pants, and you grazed your fingers over it, making him hiss.Your walk wobbly, throwing him a bone letting him feel you up.

"I'll take care of this later…" you whispered. "She’s waiting." You say, slipping your panties in his pocket.

The reminder of his date hit like a slap, though it only made the burn of his desire for you stronger. You always had him wrapped around your finger, and now he was left to endure the torture of dinner with her—while all he could think about was how soon he could return to you.

The entire Dinner was a pure torture for him. On one side his girlfriend held his hand and across the table your foot snaking up his thigh. He choked on his food when you pressed against his bulge. “Rinnie are you okay?” both of you moved in for him. You pretended to have no clue. He gritted his teeth. If he wasn't just knuckles deep in you, he would've bought the act. It got worse from there, when you asked how long until the two of them were dating. “A week” A week. You couldn’t help but chuckle softly under your breath.

“I am glad it is working out, I was always so worried for Rinnie” You cooed, your tone laced with condescension and sarcasm, only he understood.

Rin couldn’t focus on anything else, couldn’t even enjoy the food, not when you kept getting up to pass the dishes around, reminding him with each movement that you weren't wearing any panties beneath your dress. Your dress seemed to hike, painting his memory.

By the time the dinner finally ended, Rin felt like he had been dragged through hell, his mind and body on edge. His girlfriend was completely unaware, talking cheerfully as he hastily booked a cab, desperate to get her home so he’d have you to himself.

The door didn't fully close behind Rin, and he had you pushed back to the wall. This new side to him, unravelled, pressing you harshly onto you. He spit words in your face, “I fucking hate you to my gut…Nee san” He spat bitter words, brain shutting down driven by nothing but pure hunger to swallow you. You had played him like a rag doll and it was getting clear to him. Yet, somehow even his cynicism laced you with warmth inside.

Your eyes stayed floored from underlying discomfort from his actions and not the words, “Is that what you told yourself when you went…” you paused for a second and then your eyes mirrored his, “...and found the next girl who’d give you the same feelings as me?” You read him, you read his ways so effortlessly. “I thought you’d do better Rinnie… Do you think she’ll love you the same, just because she acts like me?” your eyes, endearing, a perfect escape for the devil to reside in. He found himself unable to escape from his reflection he saw in you. “She won't take care of you… like I do.”

You sheepishly slipped into his side, his heart raced when you were so close to him. He knew exactly where it led. “Rinnie'' You said in a low voice comforting his little insecurities. “I know you better than they all can ever…” Pulling away, leaving a trail of kisses along his cheek all the way till his body was reacting on its own, throwing his head back, making you climb on him, letting it linger for a moment til he regained himself of what he truly was. Vile. “...ever try to be. I won’t let them take you from me…” You cupped his cheek, without a hesitation he was drawn into your brace. Head resting on the soft fabric hearing his heart thump. He found himself unable to escape from the gentle arms that hung loosely. Words lost his way from his mouth,, but this was far more comforting than anything in his life has ever felt. “She won't take care of you… ” Your words dizzied him, lulling him to a sweet song, until all of him was reduced to you. His hands slipped past your waist under your guidance, you ignited his crave to touch you bare, to kiss you on the mouth you taste you just once.. “You understand what I'm saying, Rinnie?” he nodded like a lost puppy completely taken by you.

“They don't love you like I do” You say, fidgeting with the wool. “You’ll stay with me Rinnie? Won’t you?” It was crazy how much effect you had on him, as you slowly unzipped the long strained pants, leading him by the couch as you straddled in his lap. Your sensitive skin settling itself in his hardness. Arching your back, as you felt him poking harder, growing into a rock under you. Rin couldn't fight you, not when you sat on him like a dream, dress dishevelled, soiling his pants from the stickiness of your thighs as you dripped. Your breasts spilled from the loose dress. He didn't spend another second, pulling it down as he latched hungrily on your skin. Rin was never the type to savour a taste, just the utter fascination of swallowing you as a whole ran through his mind. You didn't hold back, and he, hell bent on draining you of your moans and oxygen. You bite your lip when he squeezed your supple breasts. Putting your nipples between his teeth, playing in his mouth. The pain had you teared and overwhelmed you but the pleasure of his obsession overpowered. You were softer than a feather, and so god damn fragile, how could he ever dream of anybody else. His tongue swirled around, teasing you painfully. Rin, didn't realise his strength as he pulled your hair, bending you to his pleasure, nothing but flesh for him to eat. He sucked harder, each time you whined, and his canines dig in deeper. He was beyond gone. Painting you in a shell of bruises, as you ran fingers in his hair. Nothing was more rewarding to see him at his worst, turned into an animal for you, for you alone. The adrenaline rushed into your brain, as you bled a little from his harsh bites, his teal eyes, cold in lust and hatred. You came a little undone just from bare sight. “Cumming just like that, Neesan?” He mocked but it only made you wince, as you licked the corner of your mouth. You pushed his hair back, watching his tongue hanging low, licking his ear, “You need me… don't you?” The tone, the words, your confidence unshakingraged him, his eyes darkened hating to admit the truth. “Then have me…” It snapped, this wasn't about Sae, it was just this urge to be seen and loved by you. Like you were right now. It was twisted, but you were so convincing, feeding yourself to him.Before you even finished, Rin pushed you over the couch, you giggled at his restlessness taking off his sweater, cracking his neck. YOur fingers traced his rock abdomen, pleased as your small frame glistened in his spit. Before you knew he was unbuckling his pants, eager and driven. You were going to keep him with you forever.
