~
âThis is so easy, how are you not understanding?â Hyunjae is hunched over beside you, scowling at the seemingly infinite number of red marks heâd made on your worksheet. You scoff at him.
âSorry to burst your little bubble, Lee Jaehyun, but maybe you should consider the fact that Chemistry doesnât come easy for everyone.â Maybe take that stick out of your ass and youâd see that.
Lee Jaehyun, or as most people like to call him, Hyunjae was a straight A student. He was nearly perfect in everything. Perfect grades, perfect voice, perfect face, perfect body. He was perfect when it came to the sports he played, he had the perfect family and home. The only horrid thing about him was his attitude.Â
He was cruel. To you, at least. Maybe just to you, his best friendâs little sister. Maybe he just didnât like you because you always seemed to be around, always trying to one-up him in everything related to school. Trying to be better than him at math, at english, at extracurriculars. You joined the debate team in high school just to spite him. And heâd be damned if he ever said he felt threatened by you.Â
If you were being honest, you really didnât hate him. You liked him, even though he clearly didnât care for you. You looked up to him, similar to how you looked up to your brother, but Hyunjae was different. He wasnât just your brotherâs best friend. At some point you started going out of your way to try to impress him, even if it never ended well for you. You wanted to spend more time with him, get to know him more.Â
âI would think that youâd be decent at this,â he sneers at you, âgiven how you seem to be so good at everything else.â You bite down on your tongue and turn back to the worksheet. The mistakes youâd made were so silly, so you understand why heâd be confused that youâre getting them wrong. Simple miscalculations when balancing equations, simple miscalculations for enthalpy. All of them were simple, and yet somehow you consistently got them wrong. âYour brother wouldnât be making these mistakes. I thought you idolized him.âÂ
âIâm not Sangyeon,â you snap. âPlus, why would he be taking a chemistry class as an Econ major? He doesnât need this shit.â
âGen eds, doll.â Hyunjae smirks at you. âWe all had to do them at some point.âÂ
Your tongue was starting to hurt from how hard you were biting on it to avoid yelling at him. Youâd forgotten that Sangyeon and Hyunjae were already in their third year of college while you were barely starting your second.Â
âDonât call me doll,â you slide your chair forward and lower your head. âGive me another worksheet.â Hyunjae shakes his head. âDude, give me a worksheet. Let me try again.â
âIâm not giving you another worksheet,â he says as he begins to pack up his things. âYou clearly arenât understanding anything Iâm teaching you, so why should I keep helping?â You rise from your chair at the same time as he does, your eyes going wide.Â
âThereâs no way youâre giving up because I get mixed up sometimes.â He looks down at you, almost annoyed that youâre still talking to him. âLee Jaehyun, you cannot be serious.â
âIâm dead serious, doll. I donât know why your brother asked me to help you when itâs clear thereâs nothing I can do for you.â He turns to walk away, and your hand latches onto his wrist, attempting (and failing) to pull him back. Heâs taller than you and definitely a lot stronger. You barely even get him to wobble on his feet, and he hardly stops walking toward the exit of the library. Now, youâre just being dragged along with him.Â
âWhy do you hate me so much?â You jog to stand in front of him, walking backwards (in hindsight, you shouldâve known that was a bad idea). âLike, Iâve never done anything wrong to you but you just fucking hate me for no reason. Why?â Heâs looking down at you while he walks, jaw tense and eyes narrowed into a glare.Â
âYouâre stuck up and think youâre better than everyone.âÂ
âYeah, but so do you!â You argue.Â
âYouâre more annoying about it though. Like everyone has to know that you think youâre better than them.â He spits out, and the two of you stop walking, standing outside of the library. The cold air of November bites into your skin, slipping through the gaps of your knit sweater. âYou just have to brag about every achievement you get, about every goal you make in soccer, and every award you get from school. You think youâre just some fucking princess that everyone needs to bow down to.âÂ
âAgain, youâre the same way!â You snap. Youâre walking backwards again, hardly paying attention to where youâre going with how focused you are on Hyunjae. âYouâre constantly shooting me down, when all Iâve ever done is look up to you! All Iâve ever done is try to impress you, but you just have to make me feel bad about myself huh?âÂ
Hyunjaeâs eyes widen a fraction, his lips parting as he listens to you talk. Heâs not walking any longer, but you are. Youâre backing toward the stairs leading to the parking lot and he reaches forward to stop you.
âDoll,â he tries to get your attention but youâre on a tangent now.
âMaybe I went too far sometimes, but itâs only because youâre my brotherâs best friend and I wanted you to notice me!âÂ
âDoll,â Hyunjae tries again and takes a step forward. Youâre getting closer to the first step, just inches from backing off the edge.Â
âBut youâre right. Little old Lee Y/N canât possibly be worth helping, sheâs too dumb for you isnât she? She isnât enough for you to notââÂ
âY/N!â Hyunjae lurches forward when your foot slips from under you. For a moment you flail in the air, arms waving while you attempt to get your balance. Your brotherâs best friend grabs one of your arms, yanking you toward him and pressing you tightly to his chest. Your body spun, and you found yourself pressed against the railing, your face squished against the tall man who had his arms wrapped fully around you.
You can feel your heart pounding, and you can feel his own, Itâs rapid against your cheek, slamming against his ribs. Heâs warm. His body is warm, and your hands tighten around his jacket. Call it desperation, but you know this is the only time Hyunjae would ever touch you and you wanted to make the most of it while it lasted.
âAre you dumb?â Hyunjae pulls you away from you, holding you an arms-length away while he scans you over. âWhy the fuck would you walk backward near a staircase?â He looks angry, and you duck your head into your chest.Â
âIâm sorry,â you mutter, âI know it was stupid but I justââÂ
âWhat if you had gotten hurt, doll?â He interrupts, his grip on your shoulders tightening. âWhat then, huh? Iâd never be able to forgive myself.âÂ
âDidnât realize you cared that much about me,â you try to joke. His frown only deepens, and you begin to shrink in on yourself.Â
âOf course I care about you!â Your heart begins to pound again. âYouâre my best friendâs little sister, why wouldnât I care about you?â And then it sinks. You just got best-friendâs-little-sister-zoned.Â
You wonder if he ignored everything youâd said before the fall. Maybe he did. Maybe itâs for the best that he did. Save yourself the rejection, move on with your life. Easy enough.Â
âI dunno,â you shrug, âfigured you hated me enough to let me fall.â Hyunjae scoffs and grabs you by the arm to start dragging you back to the car.
âIdiot.â
~
âSo what youâre telling me,â Haknyeon sits across from you, his chemistry textbook open but going ignored as he listens to you talk about what happened with Hyunjae. Since the staircaseâŚincident he hasnât spoken to you, and you really needed to pass chemistry so you enlisted your friend to help. âHe calls you doll, acts like he hates you, then you confess to him and fall down the stairs, he saves you in the most romantic way, then brotherâs-best-friend-zones you?âÂ
âYeah, pretty much,â You dig your pencil into your lip, listening to it click while you read through one of the practice problems that Haknyeon gave you. âAnd since then he hasnât spoken to me.âÂ
âWhat a dick. Youâre doing that one wrong, by the way.â He slides his chair across the libraryâs old carpet to sit next to you. âFinding the delta-H of a reaction is products minus reactants, not the other way around.â His shoulder is brushing against yours while he explains and writes down how to do the problem correctly.Â
One of the doors to the library opens and you glance up, almost immediately locking eyes with Hyunjae. Your stomach sinks when he narrows his eyes at Haknyeon.
âOh shit,â you mutter, dropping your gaze again.
âPlease donât tell me that Lee Hyunjae just walked into the library and currently looks like he wants my head on a spike.â Your friend is now frozen, speaking quietly out of the corner of his mouth.
âI will not confirm nor deny any of what you just said.â
âIf that man kills me, I will kill you.â Haknyeon hisses, and you just smile at him. Hyunjae is sitting at a table nearby, and you feel that familiar sinking feeling in your chest when he looks at you again.
âHeâs not gonna kill you. Laugh as if I said something funny.â You jab him in the side and he starts cackling loudly, gathering the attention of several other students around you. âNot that loud, genius!â He quiets his laughter, and you can see the flush rising on his cheeks. âGod youâre dumb.â
âWhat am I supposed to do? The hottest man Iâve ever seen looks like heâll snap me in half if I touch you! Iâm terrified!â He grabs you by the shoulder, and you hear his chair scrape against the ground. âOh god heâs gonna kill me and itâs your fault, you bitch.âÂ
âY/N,â Hyunjaeâs hand comes to rest on your shoulder, and he bends down to the opposite ear so you can hear him better. Your body goes rigid, and you feel his breath brushing against the side of your neck. âA word, please?â You turn your head, leaning back so you arenât so close to him. Heâs staring at you, a mix of emotions swimming in his eyes.Â
âUh,â you glance at your friend, but heâs already shoving his face back into his textbook. âYeah, sure. Hak, Iâll beââ
âYup, go ahead, have fun.â Your friend spits out and then Hyunjae is pulling you up and walking you toward a dark corner of the library.
âIs this where you kill me?â You joke, but he doesnât laugh. Heâs facing away from you, hands shoved into the pockets of a loose jacket. âDamn, killjoy much?â
âYou sure move on fast, huh?â You reel back and he turns to face you completely, a small smile practically stapled to his lips. âWith tutoring, I mean. You were able to replace me just fine.â
âOh, uh,â you blink, âyeah I guess. Hak is a greatâŚteacher? Jaehyun are you okay?â His jaw tenses before he responds again, taking a few steps toward you until heâs just inches from you, and youâre pressed against a bookshelf.Â
âYou know youâre the only person who calls me Jaehyun? Not even my own parents call me that.â His head is tilted, his eyes half-lidded while he looks at you. âWhy is that?â
âI, um,â your brain is faltering, overwhelmed by him. The way he looms over you, the way his fingers dance across your waist, the way heâs looking at you like youâre his last meal. âI donâtâ spite, maybe? Jae, youâre getting reallyâŚreally close.â
âDoes that bother you, doll?â He asks, heâs only a few inches away, and youâre getting the urge to lean up and press your lips against his.Â
âN-nope. Not at all. In fact,â Your hands are wrapped around his jacket, holding him so he canât step away from you, âthis is great.â He smiles, and you donât see joy in it. You see mischief and lust.Â
âReally?âÂ
âMhm.â One of his hands slides up to grip your chin between his thumb and pointer finger.Â
âAnd what if,â his voice is just a whisper, his breath fanning your cheek when he tilts your head to the side. âI did this?â
His lips are warm against your skin. Warm, and soft, and your breath is hitching in your throat andd you know he can feel it. Hyunjae kisses your neck right below your ear, his teeth just scraping against the tender skin and his lips sucking gently. Your eyes are fluttering, your body leaning closer to his. His hand releases your jaw, finding its way back to your waist while your own hands slide up to tangle in his hair.Â
He slides his lips down, trailing them across your neck and sucking little pink marks into the skin.Â
âShouldââ you stumble over your sentence when Hyunjae pulls your shirt to the side, placing kisses to your collarbone. âShould we b-be doing this?â He hums, and the vibrations against your skin have you gasping.
âWhat do you mean, doll?â He pulls away, leaning back up to look you in the eye. His eyes are halflidded and dark, filled with the lust you had seen in his smile. Your jaw drops open a bit, your hands sliding back down to his shoulders when he leans toward you again.Â
âI justâ I meanâ what would Sangyeon think?â Hyunjae rolls his eyes. âIâm seriââ Heâs kissing you before you can finish that sentence. Itâs a rough, searing kiss and the suddenness has you gasping. With your mouth now open, Hyunjae is able to slip his tongue into your mouth. It dances along your own, tracing every inch of the wet cavern of your mouth. Your lips are slightly chapped against his, and you wonder if he notices. You wonder if he cares, but the way he groans against your mouth tells you he doesnât. That he cares only about the way your lips mold against his, the way your tongue dances against his own, and the way your body seems to fit perfectly to his.Â
âWhoââ his lips press against yours as he speaks, âcaresâ whatâ heâ thinks?â
Hyunjae presses further against you, pressing you into the bookshelf, and you can feel the kiss becoming sloppy. You can feel the spit beginning to slide down your chin, but when you try to wipe it away your brotherâs best friend pins your arm above your head. You squeak into his mouth, feeling him smile against you.Â
He pulls back just slightly, catching your lower lip between his teeth and watching your eyes flutter, listening to the whine that escapes you.Â
Hyunjae says something to you, something you donât catch, and then he squeezes your hip.
âSorry. What did you say?â He smiles, and this time you know heâs amused. Thereâs a little twinkle in his eye, and you find yourself smiling along with him.
âI said,â he drawls, âthat we should get out of here.âÂ
âOhâŚâ you hum. âYeah, no, yeah we should.â He tilts your head up again, his eyes narrowing.
âAre you okay, doll?âÂ
âYeah, yeah Iâm fine.â You reassure him, âJustâŚa little shocked, I guess?âÂ
âShocked,â he echoes, tilting his head to the side. âShocked about what, doll?â You shrug, your cheeks starting to burn from the way he stares at you.Â
âYouâre justâŚyouâre a really good kisser.â Youâre mumbling, but you know by the way his smile grows that he heard you.
âWhat was that?â He coos, turning his head so he can âhear you betterâ. You scoff. âI didnât quite catch what you said. Iâm a really good what?â
âI said youâre a dick,â you snap and push him away from you, your cheeks now blazing. He trails after you, practically giggling at the reaction he pulled out of you. Haknyeon is still at the table when you come into view and you see his eyes go wide when he sees you.
âWhatâŚhappened to you?â You grab your jacket and bag, shaking your head.Â
âIâll tell you tomorrow, Hak.â You feel Hyunjaeâs hand on the small of your back, urging you along and you watch your best friendâs eyes bug out of his head.Â
âHeâ youâ are you twoââ
âShe said sheâll tell you tomorrow, Hak.â Hyunjae says sharply, now firmly pushing you along. âLetâs go, doll.âÂ
~
Youâre in his car, straddling his waist in the backseat. Your lips are pressed against his in a rough kiss, much sloppier than in the library. Itâs a mess of tongue and teeth and spit and his skin is so warm against yours. Your hands are underneath his shirt, but his are under your own shirt. You can feel goosebumps rising on your skin where his hands trace. Your waist, your stomach, your back, underneath your breasts. Heâs so gentle with you. You, on the other hand, are rough. Your hands are digging into the skin of his abdomen, sliding across his abs and up to his chest. He hisses when your nails dig into him, undoubtedly leaving little crescents into his golden skin.Â
You pull away only briefly, a string of spit connected between the two of you. Heâs staring at you with awestruck eyes, staring at the marks he left on your skin, at the knots he made in your hair, at the stretched collar of your shirt from where he pulled on it.Â
âWhat happened to what Sangyeon would think?â Hyunjaeâs hand slip to cup your ass over your jeans.Â
âIâm not the one thatâs gonna have to tell him that his best friend fucked his little sister in the backseat of his car in the library parking lot.â You tug your shirt over your head, tossing it to the front seat. To be fair, Hyunjae moved the car into the darkest corner of the lot, but his windows werenât tinted and if security came around to check what was up, youâd both be fucked (in more ways than one). âBesides, should you really be worrying about that right now?â
Hyunjae lowers his mouth to your chest, placing wet, sloppy kisses to the soft skin while you unhook your bra and let it slide off your arms.Â
âYouâre really gonna make me do it? All on my own?â He gazes up at you and you can only smile at him.
âIf you want me to suck your dick, yeah. You will.â His grip on your waist tightens and his eyes go wide. You lift his head, connecting your lips again as you begin to roll your hips against his. He hisses out, letting his head fall back at the sudden pressure against his growing erection. You let your eyes drift closed, enjoying the friction, enjoying the pleasure each roll of your hips sends up your spine until you decide it isnât enough. Until the quiet, gasping breaths that escape the boy under you arenât enough. Until you need more.
You force yourself off of him, pushing yourself as far back as you can in the cramped backseat of his car, the little waves of pleasure dissipating as you undo the button of your pants and begin to tug them down. Hyunjae watches you, eyes hazy and chest heaving under his shirt. You pause in your motions and stare at him with a cocked eyebrow.Â
âWhat?â He exhales heavily and you scoff, kicking his leg. He hisses, lifting his head and glaring at you.
âYou really think Iâm gonna be the only one undressing? Take your shit off, Lee Jaehyun.â He sits up, leaning toward you. Challenging you.
âWhy would I do that, doll?â He coos. âI quite enjoy the little show youâre putting on for me.â You can hear the little tremor in his voice, can see his cock straining against his jeans. You love the act he puts on, the way he wants you to think heâs in charge, so you play along.
You widen your eyes, playing the role of a desperate little girl. He may be older, but youâre smarter. Youâve known him long enough to get an idea of what he likes, just based on what youâve accidentally overheard from his conversations with your older brother.Â
âJae,â you practically purr, leaning forward and letting him see the way youâre squeezing your breasts together with your arms. He watches you lace your hands together, tenses when you place them on his knees and bring yourself forward until your mouth is right next to his ear. His breathing hitches when your breasts brush against his chest. âCan you please take your clothes off, baby?â You press a gentle kiss to his jaw. âI promise Iâll be good.âÂ
He doesnât respond, but you can hear him shuffling, hear the zipper of his pants and feel him shoving the garment down his legs as fast as he can. His shirt follows after, and you lean back with a pretty little smile on your lips as you slowly pull your jeans down. Hyunjae watches you carefully, practically drooling as more and more of your skin is exposed to him. More for him to touch, to feel, to play with.Â
When the last bit of your legs is exposed and your jeans are thrown to the side, he tugs you onto his lap again. You both hiss when his fully erect cock presses against your core, when the slick fabric of your underwear brushes against him and leaves a small damp spot on his boxers. Your hand rises to the back of his neck, nails scratching gently as you begin to roll your hips again.Â
You arenât slow this time, you arenât gentle with him. You grind against him as if youâre already riding his cock. You roll your hips in gentle circles, pressing down hard with each drag of your hips. This is the pleasure you were searching for. This is soothing the ache that had been building and building since the night at the staircase.Â
You listen to the pitiful whines that leave Hyunjaeâs mouth, listen to the gasps, and the pleas. You feel the way he lifts his hips to meet yours, thrusting harder and harder with each moan of his name that leaves your mouth.Â
âD-doll,â Hyunjae whimpers, âY/N, please. âM s-so close, doll, please.âÂ
âPlease what, baby?â You lower your head to his neck, sucking harsh purple marks into his skin and running your tongue over each one to sooth the burn you know is there. âHmm? What do you need from your doll?â
âYou pro-promised,â he pleaded, squeezing at your hips and trying desperately to get you to stop. You can feel his dick twitching underneath you, and your hips only move faster and harder against him. You can see the tears welling up in his eyes.Â
âWhat did I promise, Jae?â You ask. âTell me.â
âYou promâ promised youâdâ that youâd suck me off.â You kiss your teeth, slowing your hips. Your own body is screaming at you, begging you for the release youâd just ripped away from both of you. You, unlike Hyunjae, are good at hiding how desperate you really are to have him inside of you. Heâs still thrusting into you, whining at the loss of pleasure.Â
âI did, didnât I?â You run the back of your hand down his cheek and watch him lean into your touch. âI canât let my baby suffer now, hmm? Not after he asked so nicely.âÂ
Hyunjae watches in awe as you slide to the ground in front of him, tugging his boxers down with you. He watches as you brush your hand over his leaking cock, running your thumb over the slit and digging in. He whines loudly, jerking his hips into your touch.Â
You pull your hand away just briefly to spit into your palm, using that and the pearly liquid leaking from his tip to help run your hand up and down on his length, squeezing gently when you get closer to his tip.Â
When your lips finally wrap around him, a shudder runs down Hyunjaeâs body, his back arching and his head falling back. Thereâs a brief moment between when you first put your mouth on him to when you begin to suck, one where you just watch the older boy twitch and shudder under your touch.Â
You donât linger too long, shifting and rising a bit on your knees so you can take more of him down your throat. Your hands grip at his thighs, squeezing tightly when he hits the back of your throat and you have to hold yourself back from gagging. You pull yourself back up, suckling at his tip before bringing yourself back down onto him, taking a bit more of him into your mouth. You repeat these actions until youâre able to take all of him into your mouth.Â
From there, when you take him down your throat you moan around him, letting the vibrations hit him until his hips jerk up and heâs sent impossibly farther down your throat before pulling yourself back up and digging your tongue into his slit and drinking in the precum that leaks from his cock. Heâs a whining, blubbering mess, begging you to go faster. To make him cum. To do anything except tease him, but you donât listen. You take your time, occasionally pulling off his dick entirely just to watch him suffer.Â
ââM close again,â he chokes out, barely heard above the sloppy noises of you choking on his cock time and time again. His eyes, up until this point, have been squeezed shut. Heâs afraid that if he looks at you, heâll bust right then and there. âFuck, doll, please.âÂ
He makes the fatal mistake of opening his eyes, making direct eye contact with you. His breath hitches in his throat again, his chest tightening. You look so messy, drool running down your chin and onto his balls. Your make up is running down your cheeks, your hands squeezing so tightly at his thighs.Â
It just takes you sending him into the back of your throat one more time for him to regain control of himself, gripping your hair and sitting up a bit. Your eyes go wide when he thrusts into your mouth the first time. He hears you gag, but heâs just so close. Heâs so close, and he canât help how his hips move faster and faster, each brush of his tip against the back of your throat sending him spiraling just a bit more out of control.
âYou thought Iâd just let you take control?â he hisses, tugging your face towards his hips when you try to pull away. He can hear your muffled sobs, hear you gagging on him. âLet you run this show? Pretty girl, you have no idea what you just got yourself inâtoââ He stutters his last word, his eyes rolling into the back of his head while he empties his load into your throat. He hears you choke and pulls back, letting the last ropes of cum paint your cheeks and your chin while more spills out the side of your mouth.Â
Hyunjae gasps for breath, watching you pull yourself back onto the seat with your back pressed against the door. He watches you run your fingers through the mess on the lower half of your face, bringing it to your lips. You whine at the taste of him, and he feels his cock twitching back to life already.Â
Then he notices the lack of underwear on your body. Sometime between you taking control, and him forcing it back you stripped yourself of the last bit of clothing on your body. He turns toward you, wrapping a hand around each of your legs to spread you open. Your eyes are wide again, and you try to protest when he lowers himself to be face-to-face with your sopping wet cunt.Â
âSuch a pretty doll,â he murmurs, bringing a finger to your slit and collecting some of your juices. Your body twitches, trying to pull away from him but he just pulls you closer. âSo cute, still trying to be in control of something.âÂ
He runs his tongue all the way up the length of your pussy, stopping to suck on your clit before bringing his tongue back down and repeating that again and again and again. You writhe underneath him, moaning loudly when he digs his tongue into you, practically fucking you with it before heâs slipping two fingers inside of you. You knew it would sting with just one of his fingers, but the burn of two fingers pushing inside of you and immediately beginning to pump in and out of you at a rapid pace has you crying out and curling away from him. He just holds you closer, his fingers scissoring in and out and his mouth sucking relentlessly and the knot inside of you is growing so tight, your body curling and your hands gripping his hair tightly.Â
Then your body goes slack, your vision blurring and your ears ringing as you release all over the bottom half of his face. He doesnât relent, doesnât stop drinking up your release until youâre kicking your legs and shoving his body away from you.Â
You both gasp for breath, trying to recover. Your body is tingling with your release and you can see Hyunjae leaning against the door opposite you, running his hand up and down his length while he watches you, waiting for his cock to become erect again so he can fuck you.
âSo,â his voice is rough, ânow that weâre somewhat even, I vote that we both tell Sangyeon that I fucked his little sister in the backseat of my car.â You roll your eyes.
âI just gave you the best suck of your life, and you think Iâm gonna tell my big brother that his best friend fucked me? His best friend thatâs two years older than me?â
âYouâre 21,â Hyunjae frowns, âtwo years isnât that bad. If you were 14 and I was 16, then it would be weird, but thatâs not the case. Weâre both legal adults in college.â His hand slows on his cock, but he keeps his fingers wrapped around the tip. You run your tongue over your lip.
âJaehyun, I thought you hated me. What changed?â He shrugged.
âSimple. I never hated you. Sure for a while you were just my best friendâs annoying sister, but likeâŚI dunno. I never really hated you, I just didnât know how else to interact with you. What about you? I thought you hated being around me.â
âYeah because I wanted to make out with you half the time you were around,â you roll your eyes and let your head rest against the steamed window. Hyunjae sputters out a laugh, throwing his head back and yelping when it slams against the glass. You gasp and jump forward, crawling over his lap to cradle his head.
âShit, Jae, are you alright?â You run your fingers through his hair, feeling for where his hit his head. He lets his forehead rest against your collarbone, still laughing. âWhy would you throw your head back like that?â
âYou sure have a funny way of showing that you like me, you know that, doll?â His lips press gently into your skin and you flick the side of his head. He hisses under his breath and pinches your hip.Â
âYou worry me sometimes, Lee Jaehyun.â He hums and brings his hands to your hips. âYou gonna fuck me now?â He kisses his teeth and pushes you off his lap until youâre on the leather seats again.Â
âHands and knees, doll,â he instructs and you grin.
âOoh, doggy style. Didnât think you liked that kind of thing.â You roll onto your hands and knees, lowering the front half of your torso until youâre able to lay your head on your hands and (sort of) gaze back at Hyunjae. You watch him pull a foil packet out of the center console and click your tongue. âOnly use one if you want to. Iâm clean and on birth control. As long as youâre clean and fine with it, you donât have to.â You watch the man behind you shudder again.
âGod, Sangyeon really is gonna fuckinâ kill me, doll.â
âProblem for tomorrow, really.â You suck in a sharp breath when you feel his tip pressing into your entrance. A quite whine escapes you at the stretch, and Hyunjae rubs your sides to sooth you while he continues to slowly press himself inside of you.
âAlmost there, baby.â He assures you. âJust a bit over halfway.â
âAre you shitting me?â you whine. âWhy the fuck are you so big?â
âGood genetics, doll.â You feel his hips against your ass and your body relaxes slightly. âTell me when, okay?âÂ
âJust fucking go already,â you hiss, fighting through the stretch. âGod, just fuck me Hyunjae, please.â Your hips roll back against his and he exhales shakily.Â
âYouâre gonna be the death of me.â
âItâs either me or my brother, pick one baby.âÂ
Your teeth dig into your lip when Hyunjae gives an experimental, shallow thrust into you. He pulls out a few more inches and thrusts into you again. When he pulls himself out all the way to the tip, he inhales sharply before plunging into you. Your body jerks forward at the force of it, a moan escaping you, and then heâs plowing into you at full force.Â
Hyunjae drives his hips into you hard and fast, your body jerking forward so much that you have to grab onto the door to stop yourself from hitting it. The moans you let out become loud cries and screams of his name and you know that if thereâs anyone left in the parking lot, theyâll know exactly whatâs happening. You can only pray that they know better than to approach the window, pray that they canât see the way you beg for Hyunjae to move faster, to go harder if that were possible.Â
âSuch a good, pretty girl for me,â Hyunjae tangles a hand in your hair, yanking you back into his chest. The new angle has his cock driving into that spongey spot inside of you time and time again. âSo pretty like this, filled with me. But what would Sangyeon think, hm? What will he think of his pretty little sister getting fucked senseless by his best friend, someone he trusted to look after her while she studies?â
âF-fuck, Hyunjae, please!â You beg, clawing at his hands and his hips and the back of his neck. âFuck, harder, baby, harder!â
âYou want me to go harder baby?â Hyunjae coos, sliding one of his hands down to your clit. âWant your brotherâs best friend to fuck you until you canât breathe? Until youâre begging me to stop?â
âYes,â you cry out, âplease please please, Hyunjae!â He groans, loud and raspy in your ear and you can feel your abdomen starting to tighten okay. âOh god, Iâm so close baby please! So close, so close!âÂ
âI know baby,â he grunts, âfuck, youâre so fucking tight around me, doll.âÂ
His fingers are rubbing harsh circles around your sensitive clit, the callouses of his hands providing that delicious friction to drive you straight over the edge screaming his name and squeezing tightly around his cock like a vice until he can only grind his hips into you, and then heâs groaning and warm ropes of cum are filling you and spilling out around his cock.Â
It takes the two of you a few minutes to recover before heâs pulling tissues and wipes out of his glove compartment and gently wiping away any traces of his release. When he gets to your face, he can only smile at the dazed look in your eyes.
âSo, I take it Iâm telling your brother?â
âYou can bet your ass you are.â He hums and places a featherlight kiss to your lips.Â
âYou called me Hyunjae for the first time.â You hum.
âDonât get used to it, Lee Jaehyun. It was heat of the moment.â He laughs, tugging his boxers and jeans back onto his body before helping you with your bra and underwear.Â
âI meant it, you know.â He says when heâs got you situated in the front seat of the car. You look at him with tired eyes, enjoying the heat that comes with his car being on. Your seat is reclined so you can rest on your way home, and one of your hands is wrapped in Hyunjaeâs. âWhen I told you that I never hated you. And if youâd let me, I want to take you out on a date after finals.âÂ
The thought brings a gentle smile onto your face.
âOnly if Sangyeon doesnât kill you first.â
~
Itâs two days later when you force Hyunjae to tell him. The marks on your neck, and the scratches on Hyunjaeâs havenât faded in the slightest, and you know Sangyeon has been asking his best friend about them.Â
Youâd been sitting on your bed with your boyfriend when Sangyeon burst into the room, yelling at you about the dishes and stopping when he saw the two of you curled up on your comforter. You could see his mind trying to click everything into place, followed by your brother taking a few steps forward and Hyunjae sliding off your bed to get to your open window.Â
âLEE JAEHYUN YOUâRE SO FUCKING DEAD!â Your brother screams out the open window while Hyunjae makes a run for his house, one hand thrown into the air.Â
âWORTH IT!â You hear him yell, and you canât muffle the laugh you let out before your brother turns on you with nothing but rage in those brown eyes of his.Â
âLee Y/N,â he hisses.
âIn my defense, it was all him.â You back away from your brother, shuffling to the edge of your room.
âYouâre dating my best friend?âÂ
âMaybe? Depends on how you react to either answer.â
âOh, Iâm gonna fucking kill you both.â
âOnly if you can catch us!â You bolt out of your room, screaming when you hear him pounding after you.Â
Maybe telling your brother wasnât the best idea. But, then again, it was all worth it in the end. Dying young wouldnât be so bad, at least in your eyes.
