he wasn't supposed to hear you, and he certainly wasn't supposed to hear you say his name… but he did. what's he gonna do about it?

⤷ chuu's 💌 ── .✦ hiiiiuuu this is my first smut ever on this account. it was meant to be short but we've ended up with almost 10k words ( ╥ ᴗ ╥). i hope u enjoy and lmk if i missed any tags hehe

——

it had been years since you'd added his number to your phone, but thinking back, you weren't sure you'd ever used it before. his name was in the wasteland of your contact list, one without a profile picture or even an emoji to identify him as someone you saw almost every day.

lee heeseung.

that was all it said.

yoona was your very best friend, the only person who still remembered the time you'd cut your own bangs in the 5th grade (which she took care to remind you of all the time), or when you broke your wrist riding a bike for the first time. it was old-school. no you without her.

and with her, came heeseung.

the older brother.

heeseung was two years older than his sister—quiet, careless, indifferent. as long as you'd known yoona, you'd known him, and you were over often enough to be accepted as part of the family.

heeseung was always unfazed by your presence—hanging out in the kitchen, leaning over the counter with yoona as you shoveled cereal into your mouths, or splayed on the couch, stalking one of her exes on instagram. he'd pass by without so much as a 'hello' in your direction, as if you were just as unremarkably part of the house as his little sister was.

he spent most of his time in his room, coming downstairs only to get food or another energy drink from the kitchen. he'd make his way silently to the fridge, the hood of his hoodie pulled up over his head, brown hair poking out messily from underneath, his sleeves pushed up his forearms.

sometimes, you'd find yourself watching him over yoona's phone, nodding to whatever she was saying, but paying more attention to the boy across the room.

heeseung wasn't cute, he was fine. the kind of fine that the other girls at school talked about, which annoyed yoona to no end.

"ugh, if i have to hear about my brother one more time, i'm going to lose it. he's not cool, he's a total loser. you know, y/n. he's like, gross and stupid. i have no idea what anyone sees in him."

"definitely," you agreed.

not definitely.

as much as you sympathized with your friend, you understood why people liked heeseung. he was quiet, sure, and preferred his room to anywhere else in the world, but he was smart. he got amazing grades in school, and was halfway through undergrad at one of the top universities in the country.

he gamed a lot, but he was plenty athletic. you'd seen him without a shirt on almost every summer since you and yoona first met. years ago, he was nothing but a scrawny kid with skin so pale he practically glowed in the sun. now, he was tall, slender but toned, his skin a rich honey-tan.

plus, heeseung might have been soft-spoken, but yoona had complained plenty of times about the girls he snuck into their house after their parents went to bed. the girls at his school were no different than the ones at yours—curious and eager to sidle up next to the quiet kid with the soft voice and dark eyes.

and as much as you pretended otherwise, a part of you was just as curious as they were.

it started over summer break, when heeseung came back home and the lees were set to throw their first barbecue of the season.

you were in the guest bedroom, listening to the sound of yoona's snoring on the other side of the wall. she was a sweet girl, but she tossed and turned something fierce, somehow always managing to land a punch square to your face. it was for your own protection that you slept in the guest bed, where you were safe from her thrashing limbs.

you sighed, glaring up at the ceiling in the dark. you'd tried to sleep—you were meant to be getting up early to help set up—but you were restless.

tossing and turning, you huffed in frustration. a quiet, persistent ache throbbed between your legs, heightened from lack of attention all day. this was what you got for spending nearly every day here, with no privacy to yourself.

you supposed you could do something about it—you were in another room after all... but something about it felt wrong. yoona was on the other side of the wall. it wasn't like she'd wake up, but still...

suddenly, a sound from beyond your room made you freeze, your heart stuttering to what felt like a complete stop. it drifted from across the hall, barely audible but for the way you were holding your breath.

maybe you'd imagined it. maybe it was the result of your late-night craving, just a figment of your own—

the sound came again. a moan.

blood rushed to your face as you realized what you were hearing. across the hall, heeseung was in his room, clearly still awake despite it being well past 2am.

you weren't sure if he had someone there with him, but the sound was unmistakable. he moaned again, louder this time, the sound reverberating against your eardrums. your breath hitched, the twist of desire between your legs swelling against your will.

your mind betrayed you, conjuring all kinds of images before you could even stop them. was he with a girl? his lips attached to her neck as he dug his hips into hers, bottomed out inside of her? or was he alone? head tossed back, lip caught between his teeth, those dark brows furrowed as he—

your face burned.

you squeezed your thighs together, desperately trying to think of anything other than what heeseung might look like right now. it was no use.

another groan drifted in under your door and you matched the sound, groaning to yourself in frustration. your thoughts seemed to have a mind of their own, replaying moments that should have seemed completely ordinary to you:

heeseung coming back from playing basketball with his friends, his hair plastered to his forehead, neck dripping in sweat.

heeseung lounging in the backyard, his shirt tossed over the back of his chair as he fiddled with his guitar.

heeseung making breakfast in the morning, hair a mess, lips red and pouty with sleep, his hand brushing yours as he handed you a plate.

you found yourself arching your back slightly, hips chasing the friction of your thighs as you pictured him. what would he do if he knew you could hear him? how would he touch you if you were inside his room?

your hand wandered beneath your shorts, pussy aching for some kind—any kind of touch. you were wetter than you thought, which was embarrassing and hot at the same time.

what would he do if he knew how wet you were just from hearing the sound of his voice from the other room?

you whined lightly as your fingers circled your clit, conjuring the image of his hand between your legs. your hips bucked upwards, jolts of pleasure shooting through your sensitive nerves.

outside, heeseung moaned again, louder this time, as if he were close to finishing. you slid your fingers inside of yourself, mouth dropping open. the sound of his voice mixed in with yours sent your heart fluttering.

you were disgusting. this was wrong on so many levels. yoona would never forgive you if she knew what you were doing, jacking off to the thought of her brother inside you. the vulgarity of it only made you more desperate, fingers working in and out of your leaking cunt with a hastened speed.

half-dazed you heard the sound of heeseung grunt, as if biting his lip in an effort to keep quiet. maybe you were imagining it, lost in the haze of your own dirty fantasy, or maybe he wanted you to hear it.

that thought was even more ludicrious, but it made your cunt twitch, throbbing, aching to feel him there. what would he say if he could see you? legs spread under his family's blanket, knuckle-deep in your own pussy to the thought of him.

you groaned, mouth open, head tossed back as the bundle of nerves in your stomach tightened.

"f-fuck," you whispered, squeezing your eyes shut. your wrist was slick with arousal that dripped down the back of your hand.

"heeseung," you whined quietly, grinding your hips against your hand as you imagined him leaning over you, grinning down at the way your legs began to shake.

heeseung's moans grew concerningly loud. didn't he care that people might hear? his parents were downstairs, sure, but what about yoona?

she was a heavy sleeper, you reminded yourself. he probably knew it, too. fuck, was he coming this loud every night? why hadn't you ever heard it before?

your voice scratched against your throat as you moved your other hand to your clit, rubbing tight circles above where your fingers were.

"ugh, heeseung," you said through gritted teeth, barely able to contain the sound of your voice. god, you wished he was there, wrist deep inside you, biting his lip while you moaned for him.

across the hall, his muffled voice grew frantic and desperate, the pitch rising, tone cracking. you moaned with him, for him, the feeling of your own orgasm chasing after you like a dog after its own tail.

"ah, ah, yes. yes. please— please hee— fuck!"

you shuddered, back arched up off the futon, pleasure rolling over your body. you fell back against the bed, both hands slick and shining in the dark. your chest heaved, the sound of your heartbeat pounding in your ears, loud enough to—

wait.

you paused, holding your breath. the hall had gone silent. eerily silent.

that made sense, right? from the sound of things, heeseung had been close to finishing, and in your momentary loss of awareness, maybe you'd missed the sound of it.

right?

as if in answer, your phone buzzed from under your blanket. you pulled it out and felt your heart catapult up your throat.

lee heeseung 04:12am hey 04:12am r u up?

you stared at your screen, mind completely and utterly blank.

fuck.

you scrambled for the most sensible thing to do in the situation, but it was difficult to think straight. did he know that you heard him? worse, had he heard you? your heart sank and sped up simultaneously at the implication of either of those things being true.

what would he think if he'd heard you jacking off across the hall from him? oh my god, what if he'd heard you say his name!? would he say something to you? would he say something to yoona?

you tossed your phone across the room, pulling your blanket up to your chin. just ignore it, you thought, panicked. just pretend like you've been asleep this whole time. you groaned internally at the idea of facing him the next day.

it would probably amount to nothing. heeseung was reserved. definitely not the type to approach his sister's best friend and ask if she'd come to the thought of him last night. you had no reason to worry.

he was your best friend's brother. he was off limits. always had been, always would be.

——

you tried to remind yourself of this as you sat in the kitchen the next morning, waiting for everyone else to wake up so you could start setting things up in the back. you'd slept... poorly. too anxious and too horny to get a good night's rest.

the light came in, pale and soft, through the kitchen windows, which looked out over the backyard. you were perched at the counter, feet brushing the cool tile beneath your seat, when heeseung wandered in.

you glanced at him before looking away, trying not to look guilty of anything. "didn't think anyone else was up," you said. cool. collected. perfectly nonchalant, just like you always were.

"heard the kettle," he said, voice scratchy with sleep. "didn't expect to see you, though."

"what? why not?"

he grabbed a mug from the cupboard. "you seemed tired last night. thought you'd sleep in."

something about the way he said last night made your stomach twist, your palms growing sweaty around your cup.

you looked away. "yeah... well, you know. hard to sleep sometimes."

"mm," he hummed, rifling through the cabinet for a pack of instant coffee. then, "you always talk in your sleep?"

you froze. he threw a glance back at you, one that you couldn't quite read. it wasn't accusatory, it was... curious. amused. the corner of his mouth twitched just slightly, and it took everything in you to ignore the twinge in your lower abdomen.

you swallowed. tried to play it cool. "i don't know what you mean." your voice was steady, but your hand shook slightly as you brought your mug to your mouth.

he nodded, pursing his lips as he turned away. "sure," he said, tearing the coffee packet open and dumping it into his cup. "guess i imagined it."

something about being there, alone, with him–the slope of his shoulders under his tank top, the soft hair at the nape of his neck—you were hungry, but not for any of the food he began pulling out of the fridge.

the muscles in his arms flexed as he grabbed a pan from overhead, shirt riding up to expose the tan skin at his midrift. calvin klein peeked out in black lettering over his sweats. you felt strangely bold.

"what did i say?"

heeseung looked back towards you, a hint of surprise on his face, as if he hadn't expected you to continue this conversation.

"uh, i don't know," he answered, turning away. his neck looked faintly pink. "couldn't quite catch anything from my room."

it was your time to hum, as if you didn't know exactly what you were doing. "i saw your texts this morning," you lied. "hope i didn't wake you up."

he laughed lightly, shaking his head. "nope. was still up."

"really?" you feigned, widening your eyes. "it was so late... what were you doing?"

whatever he'd expected you to say, it wasn't that.

he turned, a half smile on his lips. his mouth opened to say something when yoona bounded into the kitchen, interrupting him before he could start.

"mom's out of the shower," she said, coming to sit beside you.

heeseung closed his mouth and turned back to his breakfast.

"hey, not gonna share?" yoona complained, eyeing her brother's plate.

"eggs are right there, make it yourself."

"whatever," she scowled, muttering under her breath about what a lowsy brother he was. "dad says you have to help him with the grill. y/n, we're supposed to run to the store. my mom forgot some stuff yesterday."

"alright," you agreed. "what time is everyone getting here?"

"12, i think. so we'd better get a move on."

you downed the rest of your coffee and got up, making a point not to look at heeseung as you trailed after his sister.

yoona called over her shoulder as she grabbed her keys, "text me if mom remembers anything else!"

——

lee heeseung 09:37am mom wants pineapple 09:37am for the grill

you were surprised to see another set of texts from heeseung on your phone, only a few minutes after getting to the store.

"here," you showed yoona. "he probably meant to text you."

she nodded, adding pineapple to the list on her phone as you sent him a text back.

you 09:39am got it. yoona has the list if u think of anything else

you drop your phone into the cart, laughing about something dumb yoona said about the pineapple display. you spent half the time dutifully tracking down the things her mom had requested you pick up, and the other half goofing off in the aisles, falling into your usual giggly banter.

your phone buzzed again from the cart, hidden under a bag of corn.

lee heeseung 09:58am we're out of butter too 09:58am and eggs

you stared at the message, your chest fluttering. heeseung was texting you on purpose? he'd never done that.

you 10:00am yoona's still got the list lol

lee heeseung 10:01am i know 10:01am figured you’d see it faster

you read it twice, thumb hovering over the keyboard. technically true, but still, heeseung was texting you. your stomach did a flip as you typed out a reply.

you 10:02am i’m not as organized as her tho 10:02am might come back with ice cream instead of eggs

lee heeseung 10:03am not the worst trade 10:03am as long as it’s rainbow sherbert

you paused, smiling a little.

you 10:04am that’s a controversial opinion

lee heeseung 10:05am yeah? 10:05am you really gonna argue with the guy in charge of the grill?

you 10:05am depends 10:05am you gonna burn everything like last year?

he didn’t respond right away. you glanced over and caught yoona watching you, suspicious.

“what?”

“you’re smiling at your phone.”

you looked away. “heeseung wants butter and eggs.”

she narrowed her eyes. “right.”

you tossed a carton of rainbow sherbet in the cart. just in case.

the texts didn't stop there. everyone was busy from the moment you and yoona returned home, but heeseung still found reasons to message you with requests or snide comments—something he'd never done before, not even when you were younger and he still lived at home.

as you hurried around the house, prepping food and taking plates out, your phone buzzed continuously in your back pocket.

lee heeseung 10:44am can you bring the chairs from downstairs out

lee heeseung 11:23am does yoona have her speaker? mine's dead

lee heeseung 11:36am you still listen to this band??????

lee heeseung 11:40am mmmm they're kinda good actually 11:41am send me this playlist

lee heeseung 12:03pm i think that's jay and the guys can you let them in? helping my dad w something rn

"i'll get it!" yoona exclaimed cheerily, smoothing her hair down as she ran towards the door.

behind it were all of heeseung's friends from high school. jay was the first to come through, ruffling his hand on the top of yoona's head.

"hey yoonie, long time no see."

she glowered at him, knocking his arm away. her face brightened back up as jungwon came through the door, the color rising to her cheeks. "jungwon!" she exclaimed, throwing her arms around him.

"hey yoona," he grinned.

niki stepped around them, toting a box of beer under his arm.

"don't let mrs. lee catch you with that," you said as he held his hand up to high-five you.

"oh, true... shit— umm... here," he said, shoving the box towards jake, whose hands were already full with a colorful bouquet of flowers.

the dark-haired boy stumbled, catching the box before it dropped. "oh, sure, make me the bad influence."

"i think you have enough mom points to cancel out," you smiled, nodding down at the flowers as they shed petals over the floor.

"it’s good to see you, y/n" jake smiled.

"can you guys move! i'm starving!" sunoo exclaimed, standing on his tiptoes to see what the holdup was. he and jungwon followed yoona towards the backyard, chatting excitedly.

"hi sunghoon," you grinned, reaching up to pull the tall boy in for a hug.

"y/nnn," he cooed, eyes crinkling at the sides. "still flunking chem?"

"only 'cuz you're not around to help me anymore."

"you could call, you know."

you smiled sheepishly. "mm, yeah... but i don't wanna bother you guys. you have a lot going on, i'm sure."

sunghoon scoffed. “just because heeseung acts like he has no time for anything outside of school doesn't mean same for the rest of us.”

you hummed, following him through the house to the backyard.

outside, the air smelled of smoke and grilled meat. yoona appeared by your side, her face flushed and happy. "hey," she said. "jungwon looks good, huh." she was giddy, her schoolgirl crush back in full swing for the summer.

"he does," you agreed, following her gaze to where he and sunoo were already picking at the skewers on the grill. heeseung laughed at them, sucking sauce from his thumb as jungwon burned his hand on one.

"do you think..." she started, her cheeks going even redder.

"that you should say something?"

she looked at you sheepishly.

"hm, let me think, what have i said to you every summer since the eighth grade?"

she laughed, head tilted back. "i know, i know. maybe one day i'll be brave like you."

your stomach flipped as you looked back at heeseung. you remembered the sound of his voice in the hall last night, and the sound of yours mixed with it.

"guess i imagined it." he'd said, a knowing look on his face.

you shook your head, turning back to your friend. "come on," you said, dragging her inside. "let's get changed."

——

heeseung pretended not to notice that you’d gone, but he noticed.

his hand itched to go to his phone, to send you another text that’d send you blushing like crazy, the way you had been all day.

you and his sister had disappeared inside, presumably to change into your swimsuits, and heeseung had to mentally prepare himself for your return. to see you prancing around the backyard with all your exposed skin, and to not be moved in any way, shape, or form.

yesterday, that would’ve been simple. easy.

yesterday, heeseung had never heard his name moaned from your mouth before. he’d never considered the idea of you fantasizing about him before, but now that he had, everything had changed.

he tried to focus on the story jay was telling, but all he could think about was your pretty little hands wedged between your legs, the thought of him playing in your mind. he hadn’t intended for you to hear him, honestly; he figured you were fast asleep the same as everyone else in the house. how wrong he’d been.

his body shivered at the memory of hearing your voice for the first time, the desperate whine that was barely audible from his room. he’d never come faster in his life.

“feels like so much has changed since we were here for christmas,” sunghoon pointed out, pulling a piece of beef from its skewer with his teeth.

“they tore down the old dance studio,” sunoo said, pouting sadly. “i wish i could’ve visited one last time.”

“i know,” heeseung said, cracking a can of beer open and taking a drink. “should’ve seen my mom, she threw a fit.”

“it always feels weird being back for the summer.”

“mm,” heeseung agreed, mind wandering back to you and how long he’d have to wait to see you come back downstairs.

you wore the same swimsuit every year, a modest little one piece that, now that he really thought about it, still somehow looked unbearably sexy on you. he said a silent ‘thank you’ that you only had the one. he didn’t think he could take it if you wore anything more revealing.

“seriously, everyone looks so different,” sunoo laughed. “i ran into beomgyu yesterday. he’s got, like, four new piercings.”

“oh, yeah. i’m pretty sure yeonjun got a tattoo when he went to cabo for spring break.”

"yoona got hot," jake said casually, tossing a chip into his mouth.

"dude, shut up," heeseung cringed.

“well obviously not to you,” sunghoon teased, nudging him with his shoulder.

jungwon shrugged. “no, he’s right. she’s gotten really pretty.”

“then why don’t you ask her out?” heeseung elbowed the younger boy, grimacing at the idea of anyone finding his sister attractive. she was weird as hell, and totally immature. not at all what he’d consider ‘really pretty’.

jake nodded. “yeah jungwon, it’d be about time. you’ve liked her for, what, five years?”

“tell ya what,” jay said, holding his hand out, “you ask yoona out, i’ll ask y/n out. double date.”

“dude, ew, that’s heeseung’s sister,” sunghoon said, making a face.

“y/n’s not!”

“they’re like the same age!”

“not even,” heeseung interjected, growing tense. “y/n’s older than yoon is.”

“so what? they’re inseparable. they might as well be related, too.”

“will you shut up?” heeseung complained, quieting the others. he rubbed at his temple frustratedly. “don’t compare them,” he muttered, more to himself than anyone else.

he didn't like it when people compared you to his sister. you weren’t like her at all. you weren’t weird or immature. you were funny and intelligent, and plenty charming even without considering how pretty you were.

and yeah, you were almost the same age as his sister, but that didn’t matter. not when you’d always been the more grounded of the two—more responsible, more even-tempered, more grown up.

and he definitely didn’t need jay of all people thinking he had a chance. it was his name on your lips last night, his teasing that had you fumbling your words that morning.

“touchy,” sunoo remarked, stealing a chip from the bowl in jake’s hand.

“didn’t realize she made you so defensive,” jake smirked, handing the bowl back for him and jungwon to finish off. “if you don’t want anyone talking to her, maybe you should—“

“dude.” heeseung glared.

jay raised his brows, a knowing smirk tugging at the side of his mouth.

sunghoon let out a low whistle, tossing a ping pong ball in jake’s direction. “way to piss off your host,” he teased.

“damn, alright,” jake surrendered, holding his hands up. “possessive much?”

he has no idea, heeseung thought to himself. yes, he was possessive. it had taken one night to completely alter the way heeseung thought about you, but there was no going back now.

he wanted you.

he wanted you bad.

luckily for him, you were spending the night again, and heeseung was going to get you.

——

“jungwon said this one was pretty last summer,” yoona said cheerily, admiring herself in the mirror that hung on the back of her door. “do you think he’ll remember it?”

you glanced up from your own swimsuit, fumbling with the strings. “oh, definitely. no guy in his right mind would ever forget the way you look in that.”

“but do you think he’ll think it’s tacky? wearing the same one? maybe i should’ve gone shopping with you last week after all...”

“no way,” you assured her. “stop checking yourself out and help me with this.”

she begrudgingly left her reflection behind and took the strings out of your hands, smirking at you. “finally ditched the one piece, huh. trying to impress someone?”

you flushed. “no,” you said pointedly. “just thought it was time to change things up. m’not in high school anymore,” you mumbled.

it was the truth—you honest to god hadn’t been trying to impress anyone when you bought the bikini the week before. now, though… all you could think about was what heeseung would think about it.

a twinge of guilt rose as yoona finished with the strings, giving you an affectionate slap on the ass. “well you look amazing.” she grinned.

your stomach felt unbelievably bare as you skipped down the stairs behind yoona. thankfully, the two of you had hit the beach almost every day since getting off school for the summer, and your skin was bronzed and glowing. yoona’s sunblock smelled like coconut butter, but you still opted to put your perfume on, the familiar scent seeping into your skin.

yoona threw the back door open and you stepped out into the sunlight, eyes blurring as they adjusted to the change in light. as the world came back into view, you caught someone’s eye from across the pool.

heeseung.

you felt every muscle in your stomach clench, heat rising up your neck. his eyes were dark, greedy, barely contained. he dragged them down your body shamelessly, as if picturing what lay beneath your swimsuit, which already left little to the imagination.

it felt like his gaze was burning your skin. oh, he wanted you. there was no talking yourself out of it anymore. it was obvious from the look on his face—heeseung wanted to fuck you.

you tilted your head suggestively, holding his gaze long enough to make your stomach flutter. jay hit him on the arm, trying to get his attention back to whatever they were talking about. heeseung tore his eyes away from you, smiling. he shook his head lightly, bottom lip caught between his teeth.

the rest of the day passed in a hazy blur of heat and commotion. you and yoona managed to convince the guys to go swimming, even though sunghoon was the only one who’d come prepared with a swimsuit.

heeseung, ever the rebellious older brother, stood with his hands behind his back, flashing two beers as he conversed with jake and his mom. you and yoona smiled at mrs. lee over his shoulder as you took them, sneaking around the side of the house to where niki had snuck off with one of his own.

you didn’t really talk to heeseung. you hardly looked at him, but you felt his eyes on you. sometimes you’d glance at him and see him already looking, or his fingers flying over his phone. yours would buzz in your hand, his name popping up on your screen.

lee heeseung 04:12pm is it weird if i say you look good in my backyard

you 04:12pm yes 04:12pm but i’ll allow it 04:12pm good to know new swimsuit is a success

lee heeseung 04:13pm wasn’t talking about the outfit but now that u bring it up… yeah. that too.

your face burned at the way he spoke to you, knowing his sister was sitting right next to you and could look over at your phone at any moment. it felt risky, dangerous, like a secret shared only between the two of you.

heeseung wasn’t the only one who liked the way you looked. jay had always flirted shamelessly with you, and did so even more now. even jake paid you a few compliments, grinning as he bit his lip teasingly. none of them mattered to you, though it seemed to bother heeseung plenty.

as jay cracked another joke, causing you to throw your head back in laughter, your phone vibrated again against your leg. you glanced down at it.

lee heeseung 05:03pm it can’t have been that funny

you pretended not to notice the notification, smile widening as jay went on.

lee heeseung 05:05pm mmm like it when u ignore me 05:05pm keep letting him think he has a chance

you 05:06pm hm jealous much?

you typed out, half-listening.

lee heeseung 05:08pm nah 05:09pm don’t need to be

you watched his text bubble appear and disappear again, a third message popping into view.

lee heeseung 05:10pm i know who u think abt when ur cumming

that wiped the smile clean off your face. you slammed your phone down, aware of the color rising up your face. across the backyard, heeseung pretended not to see you, nodding along to whatever sunghoon was saying, the ghost of a smile on his face.

you excused yourself from the table. yoona called after you as you ducked back inside, cheeks burning with equal parts embarrassment and arousal. you’d been texting heeseung all day, flirting even, but you hadn’t expected him to be that direct.

so he knew what he did to you. and he seemed to get a kick out of it, too.

you closed the bathroom door behind you, leaning against the counter as you read the message again. i know who you think about when you’re cumming. it was so vulgar, so direct, it sent a jolt of desire shooting straight down your body.

the door opened in front of you, taking you by surprise. before you could announce yourself, heeseung was sliding into the bathroom, closing the door behind him.

“heeseung—” you started, scrambling for something—anything—normal to say that wouldn’t reveal that you were looking at his texts.

he didn’t wait for you to finish.

you tensed as he closed the small gap between you, pressing you back into the edge of the counter, hands grabbing your hips. a small yelp escaped your mouth as he came closer, tilting his head to kiss you—to kiss you!—against the sink.

his mouth was soft and warm, opening against yours with a sense of urgency and desperation, as if he’d been holding himself back from grabbing and kissing you all day. your hands snaked around his neck, fingers digging into the back of his hair, earned a shaky breath from him, his grip on your hips tightening.

he groaned frustratedly. “i was gonna be good,” he grumbled, chasing the heat of your mouth. “was gonna wait.”

“then why didn’t you?” you asked, the pressure of his lower body pressed sending your head spinning.

“because you laughed at jay’s stupid joke like that. and tried to act like i wasn’t driving you crazy,” he said breathily. he smirked at you. “like you weren’t moaning my name last night.”

you whined against his lips, grabbing his shoulders and pulling him closer. his skin was hot under your fingers, warm from the sun beating down on him all day. he smelled like chlorine and grill smoke, lips sweet with the sugary taste of pineapple and beer. your thighs squeezed together, desire bubbling up your stomach and wetting the inside of your bikini bottoms.

“you really think i didn’t see you looking at me when yoona wasn’t around?”

“heeesung,” you whined, pressing your thighs together needily.

he pressed his lips to your neck, sucking harshly at your skin, followed by a rough bite. you hissed. that was definitely going to leave a mark, but you couldn’t find it in yourself to stop him.

“you think i don’t know who this swimsuit is for?” he said, voice low and growling, possessive.

you shivered as his hands slid up your waist, pushing under the strings that tied behind your back. his palms were cool against the heat of your skin, sending goosebumps rising up your arms.

“didn’t know you were such a tease, y/n,” he said against your neck, digging his fingers into your back. “walking around and smiling all pretty at everyone here. sunghoon likes you, did you know that?”

you did. he’d told you years ago how much he enjoyed spending time with you. it wasn’t a big deal. he wasn’t hung up on you or anything, but the way heeseung’s fingers pressed into you, you’d have thought sunghoon had challenged him about you.

“but he’s not the one you get off to, is he?”

“mmhm.” you shook your head, stabling yourself against the counter as heeseung’s knee pushed between your legs.

“no,” he purred, dragging his tongue across your skin. “it’s me. you moan all pretty just for me. can you do it again? wanna hear your voice, just like last night.”

your ground your hips forward, the pressure of his leg between your thighs sending your head falling back in pleasure. “heeseung,” you moaned, brows furrowing. “want you.”

“what’s that?”

“i want you,” you repeated, bringing your head up to look at him. he was watching you with his lip in his teeth, pupils blown as he took in the sight of your body grinding against his. “i want you really bad. didn’t… didn’t get enough last night.”

“of course not,” he said. “getting off to the sound of my voice isn’t enough for a pretty slut like you, is it? you just couldn’t help yourself, huh? the sound of your best friend’s brother coming in the other room got you all horny. did you touch yourself?”

he already knew the answer to that, but he wanted to hear you say it. you nodded, gripping his shoulders like they were the only thing keeping you standing. the way your thighs shook around his leg, they might have been.

“how?” he demanded, watching his hands on your waist in the mirror. the line down your spine twisted as you worked your hips against him, those cute little dimples in your back rising and falling above the waistline of your swimsuit.

“my hands,” you answered breathily.

“both of them?”

“mhm.” you nodded.

“fuck,” he whispered, moving his hands down to your hips, dragging your hips harder against his thigh. “you wanted it that bad?”

you nodded again as your upper half fell back over the sink, your elbows propped on the counter. he watched your stomach stretch and contort, the fabric of your bikini sliding over your skin.

“mmm,” he hummed, pressing his mouth to your chest. “so pretty. don’t remember you being this fucking pretty.” he kissed his way up your throat, stamping his lips over your jaw and cheek.

“heeseung,” you said quietly, looking up at him with that adorable twist in your brows. “i want— i need to feel you. want you. now. please?”

he smirked. “can’t even wait for my friends to go home? or maybe you want them here. want them to hear me make you say my name again?”

“i don’t care,” you complained, wrapping an arm around the back of his neck. “just want you.”

his lips curved into a smile. “yeah?” his hand trailed down your stomach, squeezing into the small space between your hips and his leg. “just had to ask, baby. been waiting all day for you to ask.”

you growled impatiently, pushing his hand beneath the fabric of your swimsuit where you were burning hot and soaked. he groaned, lips tickling over your neck—

knock, knock.

you both froze.

another knock came, louder this time.

“heeseung?” sunghoon’s voice floated through the door. “are you in there? jake fucked something up with the grill."

you felt heeseung’s breath hitch against your skin. you were still wrapped halfway around him, his hand still between your thighs.

he swore under his breath. “yeah, two seconds,” he called, voice wavering slightly.

you smirked, finding the situation funnier than you probably should have given how seriously fucked you’d both be if you were discovered. just to tease him, you pressed your hips against his hand again. it was just an inch, but he hissed, eyes darting up to yours. “you’re the worst,” he whispered.

you grinned, gaze going from his lips to his eyes. “that’s what you get,” you replied. “messing around with a—what was it you said? ‘pretty slut like me’?”

he kissed you once—a firm, frustrated press to your lips—then straightened, dragging his hand through his hair as if it might help calm him down. “coming,” he grumbled, opening the door just wide enough to slip through without sunghoon seeing you.

you watched him go, half-dazed, as the door clicked shut behind him. you didn’t dare breathe until you heard his voice outside again, casual and unbothered, fade down the hall. “yeah, yeah, i got it.”

——

the evening came and went in a blur. you were distracted—you knew it, the others knew it. yoona had to repeat things multiple times, snapping to get your attention, teasing you about what a blockhead you could be at times.

“seriously, what’s up with you?” she asked, crossing her arms suspiciously.

you gave her a sorry look, trying to ignore the way your swimsuit bottoms clung to your skin, sticky and wet from how turned on heeseung made you. “i’m sorry, i think i’m just tired.” you lied. “didn’t sleep very well last night.”

“you’re a champ, y/n,” yoona’s dad said, clapping a hand on your shoulder as he passed with a pile of dishes. “thanks for helping out all day. don’t know what we’d do without you.”

and if you knew i was about to fuck your son in the bathroom ten minutes ago? you thought, smiling up at him. hopefully, you’d never know the answer to that question.

the boys helped clean up like the good friends they were, arguing over who got to take the leftovers home. mrs. lee laughed at their eagerness, promising to make more for everyone to take home.

“are you guys going to the beach?” she asked, handing you another stack of plates to put away.

“hell yes,” yoona interjected, staring them all down. “we have to. it’s a tradition.”

“actually, yoona…” jungwon said, looking up from the sink. “i was wondering… well, that new disney reboot is out. it’ll probably be pretty bad,” he chuckled, cheeks pink. “but the last showing is tonight… do you want to see it with me?”

the way yoona’s face lit up, her eyes going wide like two saucers, you’d have thought jungwon had gotten down on one knee and asked her to marry him. she agreed eagerly, scrambling upstairs to change clothes, dishes forgotten.

“lame,” jay drawled. “you’re really ditching us for a girl, wonie?”

“am not,” jungwon shot back, tsking as he turned back to the sink. “it’s not a girl,” he muttered seriously. “it’s yoona.”

“well, we’re going anyways,” jake decided. he turned to heeseung’s parents. “you guys wanna come with?”

mrs. lee smiled. “that’s sweet of you, jake, but no. we have plans in town.”

mr. lee wiggled his eyebrows. “take notes boys. thirty-four years and i still take her out on dates. you know what they say—”

“yeah, yeah, happy wife, happy life,” heeseung finished for his father. “you say it too often for us to forget.”

“you’re coming with, right, heeseung?” jay prompted, emptying the contents of a chip bag into his mouth before tossing it in the trash.

your throat tightened. his eyes were on you, you could feel the burn of them on your skin.

“i don’t know, i’ve got school stuff,” he said casually.

“dude, it’s the first week of summer. what could you possibly have to do?”

heeseung raised a brow. “and this is why i go to the school i do, and you go to the one you do.”

“oh, whatever. piss off, ivy league.”

“language,” mrs. lee reminded him, raising her brows. jay mumbled an apology, making a face at heeseung as she turned to you. “i guess you’ll be staying behind too then, y/n?”

you looked up, eyes wide. “what?”

“i thought i heard you say you were tired. you’re welcome to stay here while we’re gone, get an early night.”

“although, i cant promise yoona won’t wake you when she gets back. i’m sure she’ll have lots to tell you,” mr. lee said, winking at jungwon, who turned bright red.

“right, okay,” you said simply, ignoring the feeling of heeseung’s eyes on you. “thanks, guys.”

“you guys get out of here, we’ll finish up,” mr. lee said, ushering you out of the kitchen. “thanks for your help today.”

people started peeling off after that, jake and sunghoon racing to see which one got to the car first. yoona held you hostage upstairs as she tried outfit after outfit on, growing more despaired by the minute.

at one point, jungwon poked his head in the door. “you almost ready, yoona?”

“jungwon!” she shrieked, pushing him out of her room. “get out of here! i still haven’t figured out what i’m gonna wear.”

he gave her a confused look as she shoved him down the hall. “why does it matter?” he exclaimed, “you look pretty regardless.”

“god! out! out! wait downstairs!”

you laughed as she came back in. “you’re gonna scare him off, yoon.”

“good. then i don’t have to worry about acting like a total idiot tonight,” she cried, clearly distressed.

“you’re not going to act like an idiot. even if you did, jungwon has known you too long to be surprised.”

“thanks,” she smiled, pulling a sweet little black sundress out of her closet. “you’re not mad?”

“why would i be mad?”

“because i’m ditching you…”

you shook your head, smiling at the stupidity that. “of course not. i’ve been waiting for this to happen for years, yoona. i’m happy for you.”

her concern melted away. “okay, good. sorry i’m dumping you with my brother. maybe some of the guys will stay around and you won’t have to hang out with just him.”

“maybe,” you answered. hopefully not.

her parents were gone by the time yoona was ready to leave with jungwon. you waved bye to them before padding quietly through the house, searching for anyone who was still around.

by the time you made it back outside, the sun had dipped fully below the trees, turning the backyard a dusky purple.

heeseung was already there, sitting at the edge, legs dangling in the water. he didn’t say anything when you stepped out, just turned to watch you, taking a sip of his beer.

“everyone’s gone?” you asked.

“yup. just you and me now.”

you sat down beside him, grabbing the bottle from his hand and taking a drink. “kind of nice like this,” you said, relaxing into a state of silence you hadn’t had since the early morning, when he’d first come into the kitchen.

heeseung didn’t say anything at first. the sky went to navy, the light from the pool the only thing that illuminated his face in the dark. then he looked at you, nodding towards the water. “come on.”

“what?” you asked, watching as he stood and pulled his shirt over his head. you exclaimed as he dove in, splashing you with water.

“come on,” he insisted, breaking the surface and shaking the water from his hair.

you raised a brow at him. “thought you were trying to be good.”

he hummed, the light glinting off his earrings. “i said i was. doesn’t mean i still am.”

you sucked in a breath as he waded to your legs, sliding his hands up the side of your thighs. you let him pull you into the water, the feeling of his arms wrapping around you sending heat up your abdomen.

he grabbed your legs and wrapped them around his waist, leaning forward to press his mouth onto yours again. it was slower this time, more deliberate. his tongue curled against your lips, teasing them further apart to kiss you deeper.

hours of pent-up tension rose inside you, a soft sigh escaping you as he kissed you harder—sloppy and desperate.

“fucking pretty,” he mumbled, bringing his lips down your neck. “couldn’t stop looking at you all day.”

you gasped as his teeth scraped gently against your skin, arms tightening around his shoulders. the water lapped at you gently, cool against your skin. you shivered, though not from the chill. heeseung’s body was burning hot against yours, his skin flushed red from spending all day in the sun.

your fingers trailed up the nape of his neck, tangling in the damp hair there. “heeseung…”

he groaned against your collarbone, his arms wrapped around your waist. “wanted to fuck you so bad in the bathroom. fucking sunghoon—” he complained, kneeding your skin with his hands.

“leave him alone,” you laughed, pushing the wet hair back from his face. “not his fault you decided to take on grill master today.”

“yeah, well, i could hardly contain myself the rest of the day. never wanted to fuck anyone this bad before,” he mumbled, and your heart fluttered.

heeseung had been with plenty of girls before, and maybe he’d said the same thing to them, too, but you didn’t care. his words sent chills up your spine. he kissed you again breathlessly, pulling your body flush against his as his hands wandered down your body.

“could’ve— ah!” you gasped as he sucked a deep red mark into your neck. “—could’ve done something about it,” you said.

“i wanted to,” he answered, voice low. all his attention was on your neck now, pressing soft, pretty kisses into your skin, as if to make up for the teeth marks he’d left before. “wanted to drag you upstairs, or into the garage. fuck—” he paused to grin up at you. “—would’ve dragged you behind the grill if i had to.”

“mm, classy” you said. “i’m sure yoona would’ve loved that. your parents, too.”

you meant to tease him, but the fact that you two weren't supposed to be together, couldn't be seen together, seemed to turn him on even more.

his grip hardened on you, pressing you against the edge of the pool. it would’ve scraped at your back if it weren’t for his hands, providing a barrier between your skin and the rough stone.

with one smooth lift, he had you perched back on the concrete, his hands smoothing their way up your inner thighs. “they’re not here now.” he growled, pushing your legs apart.

you leaned back on your hands, watching giddily as heeseung pressed his open mouth against the wet fabric of your bikini bottons. his breath was hot on your thighs, the pressure of his tongue through your swimsuit had your eyes rolling back, body lying flat on the ground.

heeseung never actually touched you, he ate you out over your swim bottoms, mouth separated from your cunt by that flimsy little stretch of fabric. but it didn’t matter, you were a moaning mess under his tongue. your back arched, legs lifting from the edge of the pool as he pressed his face into you, lapping hungrily at your pussy.

“hee— heeseung,” you cried, fingers clawing at the concrete beneath you. your thighs trembled on either side of his head, hips grinding against his mouth.

he pulled away, wrapping a hand around your thigh as he kissed the skin next to your cunt. “so wet, baby. want you to be totally soaked before i take you upstairs and fuck the shit out of you.”

“now,” you spluttered. “now, please, don’t make me wait any longer.”

you yelped as he bit the sensitive skin on your inner thigh, hoisting himself out of the water, dripping in streams down his chest. you stumbled upstairs together, drunk on the knowledge that you had the entire house to yourself.

heeseung pushed you backwards into his room, his door bouncing off the wall as he picked you up and dropped you onto his mattress. he stood back to admire the way you looked, splayed on top of his comforter, begging him to come closer.

“how did i not notice!?” he exclaimed, crawling over you, nipping at your stomach, chest, and shoulders. “how did i never notice how fucking hot you are?”

a laugh bubbled up your throat—at him, at the absurdity of this, at how much his words delighted you. “shut up,” you giggled.

“i’m being serious,” he said, grabbing your wrists and pinning them down by your head. “how the fuck was i so fucking blind?”

“hmm, too busy sleeping with the girls at your school, i suppose,” you teased.

“fuck the girls at school,” he muttered, pulling your swim bottoms down your legs. he groaned, kissing your hips. “so fucking pretty.”

this time, when he disappeared between your legs, you felt it all. the laugh died in your throat as he curled his tongue against you, your smile turning to a gasp.

“oh, fuck, heeseung,” you moaned, twisting your fingers into his hair.

he pushed your legs back, lapping at your cunt like he was trying to lick everything up, like he couldn’t let a single drop go to waste. “say my name again, baby. wanna hear your pretty voice.”

you did as he asked, moans growing louder and louder, surely audible from outside his room. you didn’t care. you clawed at him as he sucked your clit, the cold metal of his rings bumping against your skin as he slid a finger inside you.

“mmm, nice and wet for me,” he praised, licking his lips. “what am i supposed to do with you? all needy for me. you want it that bad?” he asked.

you nodded, digging your nails into his skin.

“you’re gonna sound even prettier when i’m inside of you.”

“mhm, i’m ready,” you whined. “needed you since i heard you last night.”

“yeah?” he asked, sitting back to pull his trunks down. his cock sprang up, long and flushed and beautiful.

you nodded again. “sounded s— so pretty. never wanted to fuck you before.”

“what did you think about?”

you groaned as he pressed himself against you, coating his length in your wetness. your hips bucked, desperate for more, desperate to just get him inside of you already.

“y-you watching me,” you admitted, inching your hips towards him. “what you’d say, if you saw me.”

“oh yeah? what did you think i’d say, princess?”

you bit your lip. “that i was filthy. touching myself with my best friend in the room next to mine. that i was a filthy mess.”

he angled himself between your thighs, the head of his cock pressing against your pussy. “mm, not filthy, baby,” he said, bending down to kiss you again. “pretty.”

you arched your back, fingers trailing up his spine.

“but i can make you filthy. you want that, pretty girl? want me to fuck you filthy?”

you nodded, tears pricking the corner of your eyes. you wanted him so bad. you needed him. he was taking his sweet time, teasing you with his words, but you couldn’t wait any longer. you clawed at him, trying to pull him into you.

heeseung groaned, head dropping between his shoulders, as he slid inside you.

“fuck,” he said, pushing his hips into yours roughly. you were so wet, juices dripping down his thighs as he fucked into you, groaning.

you wriggled needily beneath him, curling your hips up to meet him at every stroke, swimsuit straps falling down your shoulders. he leaned forward and pressed his lips to your neck, admiring the series of red marks he’d left down the sides. those would be nasty the next day, but the thought of it made heeseung harden inside you.

let everyone see them, he thought. let the whole world see how good you’d been for him.

“ah— ah, fuck, yes,” you cried, digging your nails into his shoulders.

“mm, feels so fucking good,” he gasped, reaching a hand back to grab the back of your thigh. “feel so fucking good, y/n. if i’d known—” he hissed, biting his lip. “if i’d known you felt this good, would’ve fucked you a long time ago.”

“please, heesung,” you whimpered, scratching down his back until his skin stung.

“should’ve been my first,” he panted, curling his fingers into his blanket. “wouldn’t have known what to do with you, all wet for me like this. would’ve finished the second i was inside.”

you reached your hands out to rake them through his hair, fingers curling around the soft strands and tugging, needing more. he moaned, hips stuttering into yours as your mouth attached to the side of his neck, your tongue soft and wet on his skin.

his mouth fell open, a moan scratching out the back of his throat as you stretched around him, taking him so well.

he rocked forward, buried so deep inside you that your waist stretched, head pressing back into his mattress. he filled you just right, making sure to give you every single inch until you were crying out, gripping his arms.

he watched hungrily as your face twisted, eyes squeezed shut, those pink lips of yours parted in ecstasy. it was like he couldn’t even feel you on his cock, he was too preoccupied with watching every subtle change in your expression. he felt like he could watch you for hours, panting, tongue lolling as he buried himself deeper inside you.

you clamped a hand over your mouth, thighs squeezing him on either side as he bottomed out inside of you. he snatched your wrist away from your face.

“don’t do that,” he warned, breathless. “let me hear you. tell me how good you feel, baby.”

“heeseung, i’m—” you wailed, twisting your head to the side. "feels so good."

“that’s right, show me how filthy that pussy is, princess. make a mess on me.”

your brows furrowed, beautiful, as he leaned down, swallowing the sound of your cries. you groaned against his tongue, grinding your hips against his, the friction against your clit sending your head reeling.

“come on, baby,” he coaxed. “i’m right here. take what you want.”

you moaned, low and guttural.

he grinned gleefully at the way your voice broke, thighs shaking around him. your body tensed under him as he pressed his forehead against yours, pulling him closer by the neck.

surely, the neighbors could hear you now. heeseung didn’t give a fuck. he wanted to see you all the way undone. wanted to see how loud you could be for him.

“i’m—” you gasped, “i’m gonna—”

“good girl,” he praised, “wanna feel you come all over my cock. i’m not pulling out, need to feel you.”

his words sent you hurdling over the edge, your hips lifting off the mattress as pleasure crashed over your body. your mind went blank, hands scrambling up his back as you moaned his name, over and over.

heeseung’s stomach tightened at the sound of your babbling, at the way your fingers fluttered over his shoulders. he ground his teeth together, groaning longingly as he snapped his hips into yours. your pussy clenched around him, riding out the height your orgasm in a way that sent stars bouncing around the edges of his vision.

he panted, hips stuttering, arms shaking, as the tension boiling in his stomach finally snapped, cum spilling out of his cock.

“f—fuck, fuck, y/n,” he moaned, grabbing the side of your face as he kissed you. you drank the sound in.

his moans vibrated against your lips, so needy and pretty, just like the night before. only this time, he was on top of you, face buried in your neck, dick still hard inside of you.

“fuck,” he drawled, pushing himself inside of you one more time, reveling at the feeling of cum leaking out around him. “stay here,” he said, eyes still closed, brows furrowed. “stay with me tonight. please?”

you laughed. “and how do you want me to explain that to yoona.”

“fuck yoona.”

“hey,” you said, frowning at him.

he shook his head. “fine. hang out with her all you want. but when she falls asleep, come here. don’t go to the guest room.”

you bit your lip, trailing your finger across his collarbone. “fine… but we have to wake up early. she can’t know i slept here.”

he scoffed, grinning as he bent down to kiss you. “fine. not a problem.” he bit at your neck again, softer this time. “we won't be sleeping anyways.”
