Y/N was always touching him. Always climbing into his space like it was hers to claim.

He never said anything. Not when she sat too close. Not when her hand found his arm, his wrist, the hem of his shirt. Not when she kicked her legs over his lap while he studied.

She was affectionate like that—obnoxiously soft. He was not.

So when she clambered over him that afternoon and plopped herself right down on his lap like it was the couch cushion, he didn’t react.

Didn’t even look up from his book.

"You’re so warm," she murmured, leaning into him.

"Hn."

She wiggled a little.

That got his eyes to flick up. Barely.

"Y/N."

"What?" she said, smile tugging at the corners of her mouth. "You’re comfy. I’m cold."

"That’s not my problem."

But he didn’t push her off. Didn’t tell her to move.

So she stayed there, straddling one of his thighs. She leaned forward just enough to hook her chin over his shoulder and let her body melt against him. Her cheek rested against the slope of his neck. She could feel the quiet, steady way he breathed.

Everything about him was calm. Controlled. Still.

It made her want to ruin it.

She shifted again, slowly this time, grinding her hips just enough to feel the seam of her shorts drag against the denim of his jeans.

A sharp inhale. Barely audible.

His fingers tightened around the edge of the book.

"Are you serious?" he asked quietly.

She blinked, innocent. "Serious about what?"

He turned his head slightly, just enough that she could see his eyes. Flat. Dangerous.

"Don’t play with me."

"I’m not," she said softly. “I’m just—sitting.”

"That’s not what you’re doing."

Still, he didn’t stop her.

Maybe that’s what made her bold enough to do it again. A slow, tentative roll of her hips, just once. And again.

It wasn’t even about getting off. Not at first. It was the feeling of it. The friction, the heat, the fact that Si-eun wasn’t moving at all—but his jaw was clenched tight, his hands stiff, his breathing sharper by the second.

She wasn’t sure when her breath started catching. When the ache between her legs turned real. When her fingers dug into his shoulders just to steady herself.

Si-eun didn’t help. Didn’t guide her hips, didn’t touch her, didn’t even shift to let her grind easier. He just watched—eyes pinned to her like he was memorizing the way she moved. The wet, shameful drag of her soaked panties against his thigh. The way her lashes fluttered and her mouth parted, panting.

She started trembling.

“I—fuck,” she whispered.

Her forehead dropped to his shoulder. Her thighs were clenching tight around him now, her hips chasing that friction desperately. His thigh was soaked. She didn’t care.

One more grind. And another. And then—

Her whole body seized. Heat burst low in her stomach, and she moaned against his neck—soft, broken, and shocked.

She came.

Right on his lap.

She didn’t even realize what happened until she collapsed against him, breathing hard and trembling, hips still twitching with the aftershocks.

There was a long silence.

Then his voice—low, calm.

“You came on my lap?”

Her heart dropped. She jerked her head up, horrified.

“I—I didn’t mean to—Si-eun, I swear, I wasn’t—”

“You weren’t trying to?” he asked, still staring at her. His voice was unreadable. Flat.

“No— I mean yes— I mean I was just—fuck,” she breathed, cheeks burning.

She moved to climb off him, but his hand caught her thigh. Firm. Heavy.

“You’re not going anywhere.”

Y/N froze.

His eyes dropped, scanning the mess between them. Her soaked shorts. The dark spot staining the denim of his jeans. He pressed his fingers against her core, slow and deliberate.

She choked out a gasp.

“…Still sensitive?” he murmured.

Her thighs twitched.

He slid his hand between her legs, brushing over the soaked fabric with featherlight touches. Teasing. Mean.

"You really couldn’t help yourself," he said quietly.

"I—I didn’t mean to," she whispered.

"But you did." He leaned in, voice like a whisper against her ear. "And now you’re going to do it again."

Her breath caught. "Si-eun—"

He hooked his hands under her thighs and pulled her closer until their hips were flush. She could feel the heat of him beneath her now—hard, barely restrained. She hadn’t even noticed how turned on he was until now.

"You think I’m just going to let you make a mess like that," he said softly, "and not take it personally?"

She squirmed. His grip tightened.

"You’ll sit still," he murmured, voice cool. “And you’ll come again.”

“But—”

“Do you want me to fuck you right here?”

Her mouth opened. No sound came out.

He watched her. A flicker of something darker in his eyes.

“You’d like that, wouldn’t you?” he said, gaze fixed to her face. “Me, pinning you right here, making you cry all over my lap.”

Y/N whimpered.

“But not yet.” He leaned closer. “If I fuck you now, it won’t be gentle. You’re already shaking. You’ll get overwhelmed.”

His hands shifted under her thighs, lifting her slightly and then guiding her hips back down—right against his thigh.

She gasped. Her clit throbbed. The contact was so much worse now—better—after coming once.

“Grind,” he ordered.

“What?”

“You heard me. Move.”

She swallowed.

Her hands found his shoulders again. Slowly, she rolled her hips. One circle. Another.

She was soaked. It felt obscene.

“Faster.”

She obeyed. Her breath was coming in gasps now, little whimpers spilling out with each thrust. Si-eun didn’t move, just watched her fall apart, his hands gripping her waist, keeping her steady.

When her thighs started shaking again, his hand slid between them. Fingers rubbing her through the damp cotton. Unforgiving. Precise.

She broke with a sob—her whole body curling forward as she came again, harder this time. Her nails dug into his back. Her vision went white.

By the time she collapsed against him, she was trembling, soaked, ruined.

He tilted her chin up. Made her look at him.

“You’ll clean this up,” he said, gaze flicking down to the mess between them. “With your mouth.”

She whimpered.

⸻

Yeon Si-eun.

That was the first name you learned when you transferred.

He was unusually cold to everyone. Didn’t speak unless spoken to. Not polite to be kind — just polite because it was expected.

He didn’t feel real. Too precise about everything he did.

You didn’t know when it started. Maybe when you first met.

You were assigned the seat next to him on your first day. You greeted him, but all you got was a low—almost annoyed—“Hello“. You frowned but didn’t think too much of it. Maybe he was just having a bad day? But the next day, and the one after that, he was exactly the same.

People told you he was like that with everyone, but somehow it still felt personal.

Or maybe it started when you were partnered up for a group project and he rewrote all your parts without asking. You asked him why.

He said they were missing everything they needed—not to the point, and overall just wrong. Or at best, unfinished.

You tried not to let it get to you. But you did.

You started noticing everything after that.

How he didn’t look at you when passing out worksheets.

How he sighed when he was paired with you.

How he always looked at you with that tired, bored expression in his eyes.

How he didn’t answer when you asked where you were in the lesson—or, when he did, muttered “I don’t know” without looking up, then solved the next problem seconds later.

How, when you had cleaning duty together, he always went over your spot again.

How, even though he was supposed to, he never gave you the full notes when you were sick — just bits and pieces — and you ended up getting a bad grade for something you didn’t even know you missed.

Speaking of grades:

You weren’t the best, but not the worst either.

You used to do enough. That was before him.

After him, you started studying harder.

Not for the grades. For the satisfaction.

You pulled an all-nighter before a math test and beat his score. Even got praised by the teacher.

You lived for the look he gave you when he found out. That slight twitch in his jaw. That moment of disbelief.

And then you did it again. And again.

Everything became a contest.

Who scored higher?

Who ran faster?

Who got more praise from the teachers?

A silent war between the two of you.

When you were forced to work together again, you redid his parts out of spite. Not because they were wrong. Just because.

Somewhere along the way—you didn’t know when—it stopped being about proving him wrong and started being about getting his attention.

You heard what people said when they thought you weren’t listening.

“You’d think they dated and broke up.”

“They act like exes who never kissed.”

You didn’t know how much it actually got to him—until later.

His grades were everything to him.

So being beaten—by you—was humiliation. The worst kind.

The breaking point came at the end-of-year ceremony.

The student with the best overall score was called to the front and honored with a certificate.

He was certain it was him. Knew the competition was close, but he still thought he’d won.

So when your name was called instead — not his — he froze. Stood up. And walked out.

People noticed. He didn’t try to make a scene but ended up doing it anyways. Inside, he was unraveling.

That was today.

Just a few hours ago.

⸻

You’re in your room, still buzzing from earlier. When you got home, your parents welcomed you like you were royalty. Proud doesn’t even begin to cover it—and honestly, you’re proud too.

Your friends invited you to a party, and you said yes without even thinking twice. Finally, you have some free time again. You never planned on being an A+ student with zero life outside school.

Now that the holidays are here, it’s time to actually use that freedom.

You sit cross-legged on the floor, surrounded by a mess of makeup and clothes. Jina’s digging through your jewelry box, holding up chunky hoop earrings with a grin. Definitely a must-have.

You can finally wear real clothes again—not that stiff, boring uniform. Real clothes mean 2000s style, and you swear this is the best look out there.

You grab a pair of super low-rise jeans and a tight sweater.

“Ayy,” Mira says, nodding approvingly. “Definitely those.”

The three of you giggle like idiots. Clothes in hand, you head to the bathroom to change.

In the hallway, you stop in front of the big mirror.

You lean back and take it all in—the low-rise jeans hugging your hips, the sweater squeezing your curves, and butterfly clips sparkling in your hair. You don’t just want to look good tonight. You want to be unforgettable. To make heads turn.

When you walk back in, your friends erupt.

“Guys, don’t—don’t—” You pretend to protest but then strike a pose, closing your eyes to show off your look.

“Don’t stop,” you laugh, feeling a rush.

“You look absolutely delicious,” Jina says, rubbing her hands together like a maniac.

“You’re gonna break hearts tonight,” Mira adds with a smirk.

“I’m just so glad I finally have time to do that again.”

“Right? I wasn’t expecting you to turn into a total nerd with no social life.”

“Yeah, that Si-eun really did a number on you.”

“Oh, stop, Mira.” You roll your eyes jokingly. If you think more about him, you swear you could explode. But today was—is a victory.

————

The party’s already loud by the time you get there.

It’s at some girl’s house—big enough to fit a crowd, but not enough to make it feel less claustrophobic. Music thumps through the floorboards. The bass hits your chest like a second heartbeat. Lights flicker in blue and pink. Someone’s already spilled beer on the hallway rug.

You step inside with your friends, shoulder to shoulder at first, but Mira and Jina quickly scatter toward snacks and boys. That’s fine. You’re not here for chips and flirting.

You make your way into the main room, cup in hand, pretending to be just another party girl out for fun.

You definitely attract looks. Some even come to you. But no one is really your type.

You are talking with a girl you just met in the corner. Your thoughts drift back to that moment Si-eun stormed out of the ceremony room.

You haven’t seen him since the ceremony. Since you were the one called up. Since he stood and walked out like the world had just betrayed him.

You told yourself you didn’t care.

But you did.

You catch your reflection in the dark glass of the balcony door—glossed lips, low-rise jeans, tight sweater clinging just right.

You raise your cup, take a sip, and lean against the wall like you own the room.

Then the door opens.

And just like that—

You feel him before you see him.

You are startled. He isn't the type to go to parties. 

“Hey, are you fine?" The girl you were just talking to asked. Searching for what you were looking at.

"Oh, is that your ex? I get it, but don't be afraid you look bomb. He's gonna see what he's missing.” You turn to her.

“No—He's not—no.” You protest, but she gives you a knowing look. 

You wave the girl off with a forced laugh, turning back toward the crowd—but you can’t help it. You look again.

He’s there.

Si-eun stands near the entrance, eyes scanning the room like he’s trying to decide whether he should’ve come at all. He’s not dressed for a party—dark hoodie, clean sneakers, the same bored expression he wears in class—but somehow, he still looks like the most important person in the room.

His gaze passes right over you at first. And then it stops.

Lands. Holds.

Your stomach tightens.

He doesn’t smile. Doesn’t nod. Just looks.

And then—like nothing happened—he breaks eye contact and walks away.

You exhale, only then realizing you were holding your breath.

“Definitely your ex,” the girl says under her breath, sipping her drink.

“He’s not,” you murmur, but it’s too quiet to convince anyone.

You take a long sip from your cup, ignoring the way your hand shakes just slightly.

Your eyes track him across the room. The way people naturally give him space. The way he doesn’t seem interested in talking to anyone, like this party is just something he’s enduring. Like he’s here for something, not just to hang out.

Or maybe someone.

You turn your back to him, pretending to listen as the girl tells you a story you’re not really hearing. You nod at the right times, give polite laughs—but your attention’s somewhere else. Heat rises in your neck.

Si-eun is only here, because he was forced to. Su-ho didn't give him the option to not go. He said he should just relax, get his mind off school. Off the… incident.

When he sees you, his heart is beating. With rage—he thinks. He looks you up and down, notices how slutty you're dressed. He tries to seem unfazed, as always. But as soon as he turns around, Su-ho notices something wrong.

Then he sees you too. He sighs.

“Si-eun, don't waste a single thought on her today. Just enjoy it. C’mon, let's get you a drink.” He drags him to the kitchen, where they then fill some drinks into their cups and go somewhere where you're not.

————

You gave up on thinking about Si-eun maybe one and a half hours ago. You haven't seen him since he entered. 

So it does surprise you when he's suddenly behind you. You almost spill a drink on him. He just yanks your hand and pulls you with him.

“What are—Hey—you doing?!” You ask loudly. Shocked.

“We need to talk.”

“No, we definitely don't!" He just pulls you up the stairs into a quiet room. Not really quiet, but it is empty, except for a cupboard and a bed. A guest bedroom. The music is muffled.

“Hey, what the fuck was that?” You ask, finally yanking your hand from his grip.

He turns to you, jaw tight, eyes darker than you’ve ever seen them.

“What was that?” You repeat, louder this time. “You can’t just drag people around like that!”

“Why do you hate me so much?” he asks, voice low but firm. 

You're thrown off. “What?” You ask Perplexed.

“You heard.” Only now you notice how drunk he is. It is obvious now that you know. He is not stable in his stance, he wanks from right to left. Slurs his words.

“Okay, I am not doing this. You’re drunk as fuck.” You turn around to open the door, but he slams a hand on it.

You flinch. Not because you’re scared, but because of how close he suddenly is.

“What are you—? Let me out!” You snap, pushing at his arm.

But he doesn’t move.

He’s leaning close now, jaw clenched, eyes unfocused but still locked on you like he’s trying to figure you out. Trying to demand something from you that even he can’t name.

“No,” he says. “Not until you tell me why.”

“Why what?” You shoot back.

“Why you look at me like that,” he says, voice low, heavy, like the words cost him something. “Why you do what you do.” 

You're quiet.

“You serious?” You scoff. “You started this! I should be asking you.”

“What?” He laughs out of disbelief.

“Don’t act so clueless! You're so arrogant, God. You ignored me every time I tried talking to you, ask something. Send me unfinished notes, which I then get bad grades because of. Just cancel all my work and do it yourself. And this look on your face—it pisses me off so much! I’m just mirroring you.”

“You’re kidding me, right?”

“Do I look like I am?”

“You’re unbelievable!” he says angrily. Loud.

Your hand is still on the doorknob, but you don’t turn it.

“Oh, I’m unbelievable? You’ve been an asshole to me since the day I got here!”

“No, I wasn’t? I just didn't know how to act around you!”

“Well, definitely not like this!”

“I didn't want this! I never wanted you to hate me!”

“I also didn't want this if you think so!”

You’re both shouting now. Face-to-face. No space. Breathing the same air.

“God, you're so—…” He begins but trails off.

He stares at you, eyes burning with something you don’t know how to name. His chest rises and falls like he’s just run a mile. You feel your pulse in your ears, in your throat, everywhere.

He looks at you, at your eyes, and then your lips.

“I hate this,” he breathes.

“Good,” you say. “So do I.”

You don’t know who moves first.

Maybe it’s you. Maybe it’s him.

But then his mouth is on yours, and it’s not gentle.

It’s messy. Angry. Clumsy. Teeth clash. Your back hits the door with a thud. His hands are in your hair, your jaw, your waist, like he can’t decide where to touch first. You pull him closer, fingers tugging on the strings of his hoodie, and he groans into your mouth like he’s needed this for longer than he can admit.

You gasp when he bites your lip—and then he pulls back, just a little, breathing hard.

“You drive me insane,” he says, forehead pressed to yours.

“You think you’re easy to deal with?” You shoot back, just as breathless.

His hands slip under your sweater. Warm skin against warm skin. Fingers skating up your ribs like a threat.

“This is a bad idea,” you say, but you’re not moving away.

He nods. “Terrible.”

And then his lips are on yours again. This time deeper. Slower. Like the fight cracked something open. Like he wants to devour you. Memorize you.

“You wore this on purpose? Mh?” Si-eun mutters lowly against your lip. He moves to your ear and whispers.

“So slutty…” His breath hitting your earlobe. You moan when he places kisses on your neck. 

You couldn't answer, too busy whimpering. Si-eun looks down, seeing your thighs press together.

“Are you horny? Did this turn you on?” He asks, amused.

What? You didn't even notice.

“Fuck you…” you try to say, but it comes out as barely louder as a whisper—more a whimper.

He laughs. 

“Yeah? Want me to stop? Pretty sure you kissed me back.” His mouth is back on your neck, and you can feel he's smirking, but it slides lower to your collarbone. He licks, kisses, sucks at it. While his hands move up to your breasts.

“Si-eun…” You breathe out.

“Stop me if you don't want this.” 

You don't.

You let him touch you. You let him kiss you.

One of his hands is at your ass now, squeezing it inside the low-rise jeans. He presses against you and buries his head in the crook of your neck while whisper-moaning your name.

You could feel how hard he is.

The muffled music from outside is a background noise now.

“As soon as I saw you, I knew. These low jeans. This tight fucking sweater.“ He kissed your neck, now only mumbling.

“I knew you’d make me this hard. You do, even in that uniform…” He rubs himself against you. 

Then he leans back, searching for any discomfort in your face. There is none. Only flushed cheeks and half-lidded eyes staring at him.

A short pause.

Then—you both launch at each other, aggressively kissing again, while your hands roam his body and his roam yours. You reach behind you and turn the doorknob, lock the door, and push him towards the bed.

You reach for the hem of his hoodie, desperately pulling it over his head, then—your sweater. He slides it off you in one fast, desperate motion. 

You kiss again as soon as you're both free. Next your hand goes to his belt, trying to undo it. He helps, smiling into the kiss. Then he reaches for your jeans. Takes them off too.

You push him on the bed, climbing on top of him. His touch burns. He yanks you down harder against his lap, grinding you onto the stiff outline of his cock through his boxers. You gasp, nails digging into his neck, the kiss turning filthy—all tongue and teeth and desperation.

His hands skim up your back, deft fingers unhooking your bra like he’s done it a hundred times before. You shudder when the fabric falls away, his palms sliding around to cup your breasts, thumbs brushing over your nipples in slow, deliberate circles. Your hips jerk against him instinctively, chasing the friction.

“Fuck,” he growls, breaking the kiss to pull back shortly to take in the sight of you before dragging his mouth down your throat. He bites at your collarbone, then lower, his tongue flicking a nipple before sucking it deep. You whimper, arching into him, one hand fisting in his hair.

Then his lips vanish. You make a noise of protest—cut off when he flips you over. Now you're under him.

His mouth is fast on your body again. Trailing kisses down your stomach while his hand tugs at the waistband of your panties.

He briefly looks at you, then pulls your panties off in one motion. His hands press down on your legs and spread them. He moves back up and leans in to place kisses on your lips again. While his fingers glide through your wetness, testing, teasing. 

You moan into the kiss. He pulls back to see your face.

“Look at you,” he murmurs, leaning back down, lips brushing your ear. “Soaked for me.”

You barely have time to process the words before two fingers sink into you, curling just right. Your thighs tremble, a moan ripping from your throat. You try to close your legs instinctively, only to be blocked by him between your legs. He works you ruthlessly, his gaze locked on your face.

His mouth is on your breast now. Sucking it. His tongue circles around the nipple, which only makes you weaker. 

You arch into him, back lifting off the bed, into him.

He works you up perfectly, and just as you think you're close, his fingers vanish and he kisses you again. It's grounding, a motion that slows you down. Deep, passionate.

You reach down to his boxers, palming him through it. He whimpers into the kiss.

When you break the kiss, your hands are at his shoulders, slightly pushing them. He understands what you want without you having to say anything.

You push him onto his back and slide down his body, fingers hooking into the waistband of his boxers. He lifts his hips to help, exhaling sharply as you peel the fabric away, his cock springing free—hard, flushed, already glistening at the tip. 

You lower your head, and your tongue darts out, flicking over the bead of precum, then swirling around the tip.

He hisses, watching you. Then you take him into your mouth slowly, inch by inch. His groan is ragged, hands fisting the sheets. You work him with deliberate strokes, hollowing your cheeks as you pull back, then sinking deep again, savoring the way his thighs tense under your palms. 

“Shit—” His voice cracks when you swirl your tongue around the head again, teasing the slit before swallowing him down once more. You glance up, meeting his darkened gaze as you cup his balls. 

His stomach muscles clench, his hips twitching like he’s fighting not to thrust. You let him slide from your lips with a wet pop, crawling back up his body. He catches your mouth in a searing kiss, tasting himself on your tongue as his hands grip your waist, pressing you down on his hips.

“Ride me,” he rasps, bucking up against you. 

You don’t hesitate, you stretched this long enough—sinking onto him in a halting motion, both of you gasping at the stretch. His hands roam your body, skimming your ribs, thumbs brushing your nipples as you start to move. 

Slow at first, grinding down, taking him impossibly deep. He grips your hips, helping you find the rhythm—up, then down, a slow, maddening drag that has you both panting. 

His fingers dig into your skin as you clench around him, your own hands braced on his chest, nails scraping lightly. 

“Fuck, just like that,” he grits out, eyes locked on where your bodies join. You lean forward, sealing your mouth to his, swallowing his groan as the pace turns desperate—not faster, but deeper, harder.

“Si-eun—“ cut off by a gasp and a slow moan.

“Still hate me?” He asks, voice wrecked.

You answer with another moan of his name and a harsh fall down his cock. Your hand reaches down to circle around your clit, working yourself closer, while your lips meet his again.

He breaks the kiss. “You don’t know how many times I thought about this—ahh fuck—“ he thrusts his hips into you involuntarily. You know, he's close.

You're too. 

“Fuck—you’re squeezing me.” His abs clench again. Almost there.

It hits you like a wave. This overwhelming sensation. The tingling is more intense than what you ever experienced before, it reached its way all the way to your heart. You shudder, leaning down on him as your whole body throbbed. Every part of you that was touching him burned.

He feels it too as he follows with one last thrust as he buries himself inside you. 

You plop down beside him, both of you panting.

After you two regain the ability to breathe—and think properly—the silence hangs in the air. The silence of the tiny confessions both of you just made, with words and—well the sheer fact that you just fucked the person you swore you would murder if he came closer than arm's length to you.

“So… that just happened.” He speaks first.

“Yeah…” 

Another moment of silence.

“Let's stop this… rivalry.” He suggested.

“Deal.” Another pause.

“I never even really hated you, to be honest.”

You push yourself up, turning to look at him. Then lay your head on his chest.

“I’m sorry I was such an asshole.” You whisper, taken aback by his confession.

“Yeah, me too.”

⸻

Pairing: Yeon Si-eun x Fem!Reader (Y/N) Rating: 18+ Content: oral (f receiving), breast fixation, slight dom!Sieun, teasing, obsession, heavy eye contact, possessiveness, creampie, lots of focus on boobs, mutual pining explosion

------------------------------------------------------------------------------

It started with the tank top.

Y/N didn’t think twice when she tugged it on that morning — thin, barely-there cotton, no bra. They’d both been lounging around the apartment all weekend anyway. She wasn’t expecting company. But the second she walked out of her bedroom and caught sight of Si-eun on the couch, her stomach twisted.

He was looking at her like he’d never seen her before.

Or maybe like he’d been trying not to look for a very long time — and something inside him just finally snapped.

His jaw tightened. His eyes dropped for a half-second — too long. She watched his throat move as he swallowed, and then he looked away completely, like if he didn’t, he’d do something stupid.

She raised a brow. "Something wrong?"

“No,” he muttered quickly, far too quickly. “You’re—fine.”

But his hands were clenched into fists in his lap. His face was red.

She smirked. "Sure I am."

Y/N walked past him slowly, making a show of reaching up to stretch on her toes, pretending to grab something off the top shelf. Her tits shifted under the thin fabric — no bra, no shame. She could feel his stare burning a hole in her back.

“Are you—” His voice cracked. “Are you seriously not wearing a bra right now?”

She glanced at him over her shoulder. “I’m home, aren’t I?”

Si-eun didn’t respond. His eyes were glued to her chest now, shamelessly. Like he was starving. Like he’d been dying to look for months and finally couldn’t pretend anymore.

“…You’re making it really hard to be respectful,” he said hoarsely.

Y/N turned, taking a step closer. Her tone was teasing, but her heart thudded loud in her chest. “I didn’t realize looking was so disrespectful.”

He let out a bitter laugh, leaning back into the couch like he was trying to escape. His thighs spread, and she couldn’t help but glance at the thick, very obvious bulge tenting his sweats.

“I’ve been trying not to look, Y/N. For so long. But you’re always—” He gestured weakly at her chest, breathing heavy. “You wear the tightest shit and just… bounce around the apartment like it’s nothing.”

“I don’t bounce.”

“Yes, the fuck you do.”

She grinned, heat pooling low in her belly. “So look.”

His eyes snapped up to her face, stunned.

“I’m serious,” she whispered. “If you want to stare, stare. I don’t mind.”

His mouth parted like he wanted to say something, but instead, he surged forward and grabbed her waist, pulling her down onto his lap. She gasped — and then his mouth was on her neck, his hands sliding under the hem of her shirt to cup her tits, thumbs brushing over her nipples.

“Oh my god,” he groaned against her skin. “They’re so soft. I’ve been losing my mind, Y/N.”

Her head fell back as he palmed them roughly, squeezing like he couldn’t believe they were real. His cock was hard under her, twitching against her ass with every grind of her hips.

"You have no idea how many times I jerked off thinking about these." His voice was ragged, almost angry. "No idea how many times I had to stop myself from staring when you wore those stupid little pajama tops."

“You could’ve had them any time,” she whispered.

That made him freeze. He pulled back to look at her.

"You’re serious."

“I’ve wanted you just as long, Si-eun.”

Something in his expression snapped. He yanked the tank top up and over her head in one swift motion, groaning low in his chest when her tits bounced free.

“Fuck,” he whispered. “You’re perfect.”

He ducked down and latched onto her nipple with a low growl, sucking hard, tongue swirling in slow, messy circles. His other hand massaged the opposite breast — not gentle, not shy — like he needed to feel every inch. She gasped, rocking against him harder.

"You like that?" he muttered, lips wet, still attached to her skin.

“Yes,” she breathed, clinging to his shoulders. “Don’t stop.”

He didn’t. If anything, he got rougher. His tongue flicked and dragged, his teeth grazing just enough to make her whine. When he pulled back to catch his breath, a trail of spit connected him to her nipple. His eyes were dark, almost feral.

"You look so good like this," he murmured, voice low. “All flushed and needy. Mine.”

She shivered. “Then take me.”

That was all he needed.

Si-eun flipped her onto the couch, yanked her shorts down in one go, and shoved her legs apart. His mouth was on her in seconds — licking, sucking, tongue moving in circles until she was shaking. And the entire time, his hand never left her chest. He was obsessed, thumb rubbing her nipple while his tongue worked below.

She came hard, crying out, legs trembling around his head.

Then he climbed up, finally yanking his sweats down, and her eyes widened — thick, flushed, already dripping with precum.

“You’re gonna let me fuck you like this?” he asked, lining up with her soaked entrance. “With your tits bouncing in my face?”

She nodded frantically. “Please.”

He slammed in all at once, groaning loudly. His hands immediately went to her chest, gripping, kneading, like he couldn't help it. She was soaking, clenching around him, overwhelmed.

He watched them the whole time he fucked her — wide-eyed, transfixed, like nothing else existed. Every time they bounced, he groaned louder, hips snapping harder.

“Look at them,” he panted. “Fuck, I’m gonna come—gonna come just from watching them—”

“Do it,” she begged. “Come inside me.”

He did. With a deep, choked moan, he buried himself to the hilt and spilled inside, grinding through it, still staring at her tits as they bounced with every pulse.

When he finally stilled, chest heaving, he collapsed onto her.

After a long beat of silence, he muttered into her neck, “I’m never gonna recover from this.”

Y/N laughed breathlessly, combing her fingers through his hair.

------------------------------------------------------------------------------

Her thighs twitched violently when he shifted her onto his lap, her limp body straddling him like a doll. Si-eun didn’t say anything at firsthe just held her there. Let her squirm.

Let her feel every drop of him still leaking out, every twitch of his cock buried deep inside.

Her head lolled against his shoulder. “Si-eun,” she whispered, too raw to speak louder.

He hummed, running one hand slowly up her spine while the other gripped her thigh. “Still with me?”

She nodded, trembling. “Too much.”

He smiled against her hair. “Not yet.”

His hands guided her hips—slow, unrelenting—as he rolled them forward, forcing her to grind down on him. Her breath hitched. Her hands fisted his shoulders, nails biting into skin, but he didn’t stop.

“You’re still dripping,” he said lowly. “I can feel it. Hot and messy.”

She whimpered, burying her face into the crook of his neck. “Please—can’t—”

“You will.” He pulled back just enough to look at her. “You’re going to take it again.”

She could feel everything. Every overstimmed nerve sparking, every fluttering contraction from her last orgasm now violently reignited by friction. Si-eun didn’t thrust up. He didn’t need to. Just the wet glide of their bodies rocking together was enough to make her see stars.

“Such a good girl,” he whispered, lips brushing her cheek, her temple. “You feel so fucking good like this—like you’re made for me.”

His grip tightened, guiding her faster now. She was moaning into his neck, hips bucking weakly on their own, chasing something even she didn’t understand anymore.

“I’m gonna ruin you,” he growled, breath catching. “Gonna fuck you until you can’t remember anything but my name.”

“I already can’t,” she sobbed, voice cracking. “Si-eun, please—”

“You begging again?” He chuckled softly, almost cruel. “You know what that does to me.”

She gasped when he shifted—planting his feet firmly on the mattress so he could angle deeper. His hands stayed on her hips, fingers digging in, forcing her to move with him now.

“Ride,” he ordered. “Don’t stop until you’re crying again.”

She already was. Tears streamed down her cheeks unchecked, a mix of overwhelmed ecstasy and submission as her thighs flexed around him. She rode him slowly at first, then faster, her body shaking each time his cock slid against that one devastating spot inside her.

He watched her fall apart like it was art.

“Faster,” he said. “You wanna come? Then fucking earn it.”

She nodded frantically, mind broken open, letting him fuck up into her in desperate, ragged rhythm. The obscene sound of skin slapping, the wet squelch of their bodies grinding together—it filled the room. And still, he didn’t look away. Not once.

His voice dropped. “You look so fucking beautiful when you’re destroyed.”

She screamed when it hit her.

No warning this time. No mercy. Just pure, violent orgasm crashing through her like lightning, her body locking up as she clenched down hard, sobbing against his chest. Si-eun groaned—deep and broken—as she milked him for a second time, her spasms dragging another hot flood from him.

He gripped her tighter and held her there—fully seated on his cock, keeping every drop inside her.

She went limp.

He stroked her back gently. “Shhh,” he murmured. “You did so well, baby. So fucking good.”

Her voice was barely there. “I—I can’t move.”

“Don’t need to.” He kissed the top of her head. “Just stay. I’ve got you.”

She felt warm. Safe. Destroyed.

And then his hand slid between them again.

She flinched. “No—no more—Si-eun—”

“Shhh.” He didn’t even touch her clit—just rubbed soothing circles on her hips, grounding her. “I’m done. I promise. Just letting you come down.”

He stayed like that with her, rocking her gently, cock still buried inside. He didn’t rush. Didn’t force.

Eventually, her body stopped trembling.

“You still here?” he whispered.

She nodded slowly.

Si-eun exhaled a shaky breath and leaned his forehead against hers. “Good.”

Then, quieter: “I love how you trust me like this.”

Her eyes fluttered open. She blinked through the haze and found his face—flushed, sweat-damp, jaw still tight from restraint. His thumb brushed a tear from her cheek.

“Even when I push you too far.”

“You didn’t,” she murmured. “You never do.”

That broke something else.

He kissed her—soft, deep, reverent.

And finally, finally, he pulled out.

Only to lay her down again, clean her up, and curl behind her—naked, breath heavy, arms wrapped around her waist, his mouth still ghosting along the back of her neck like he couldn’t let go.

“You still won’t need your legs tomorrow,” he whispered.

Title: Cold Shoulder, Warm Hands

------------------------------------------------------------------------------

It started with a laugh.

A stupid, high-pitched giggle that escaped Y/N's lips when Suho nudged her side with the end of a chopstick and made some dumb pun about fishcakes. Si-eun heard it from the kitchen, where he was refilling his water bottle. He wasn’t even part of the conversation. Wasn’t even looking at her.

But he heard the laugh. And he heard Suho's response: “Aw, that laugh is cute. You should do it more.”

Si-eun’s jaw twitched.

“Oi, lover boy,” Bumseok teased as he flopped onto the couch beside him later, elbow knocking his. “You’re glowering so hard I thought your soul left your body.”

Si-eun didn’t respond.

Suho was still talking to Y/N, way too close if you asked him. His hand lingered on the back of the chair she was sitting in, and she was smiling—no, laughing again—at whatever dumb story he was telling.

“Seriously,” Bumseok snorted. “You look like you're plotting Suho's murder.”

"I'm not jealous," Si-eun muttered.

"Never said that," Bumseok said innocently, and then leaned closer. “But if I did, you’d still be proving me right.”

It only got worse when Eunjang’s golden retriever, Ryu Seokdung, joined in.

“Y/N, wanna come with me to the convenience store? I need help picking chips.”

“She’s not your mom,” Si-eun muttered under his breath.

Ryu blinked. “What?”

“Nothing,” Si-eun said stiffly, arms crossed.

Y/N blinked up from where she was squatting by the low table, rearranging snacks. “I don’t mind! Gimme a sec.”

Si-eun’s eyes narrowed.

Ryu grinned at him as he backed toward the door. “You coming too, Si-eun?”

Si-eun should’ve said no. He should’ve said he didn’t care. Instead, he stood without a word and followed them out like a silent bodyguard.

The teasing didn’t stop.

When they returned and Y/N offered Seokdung a bite of her snack first, Si-eun turned to stare blankly at the wall. When Suho sat beside her during the horror movie and she didn’t move, Si-eun stood up halfway through and pretended to go check his phone. When Bumseok caught him stealing a glance at her while she was curled up under a blanket, hair messy, face flushed from laughing too hard—

“Oh my god,” Bumseok whispered. “You’re so gone.”

“Shut. Up,” Si-eun hissed.

“You want her to sit on your lap, don’t you.”

“I will kill you.”

Si-eun wasn’t stupid. He knew she wasn’t flirting with them. Not really. Y/N was just nice. Too nice. She smiled easily, listened too well, and let her arm brush against Suho’s for too long without noticing.

But he noticed. Every single time.

The problem wasn’t her. The problem was him.

He had no claim. No right to feel possessive. Not unless she gave it to him. And she hadn’t. Not yet.

So he sat there and simmered. Silent. Cold. Jealous out of his goddamn mind.

It boiled over the night they all stayed late at the rooftop.

Everyone was tipsy on cheap beer and convenience store snacks. Y/N had her head on Suho’s shoulder, drowsy from laughing too hard. Ryu was sprawled beside them, already half asleep. Si-eun stood on the far end of the rooftop, hands in his pockets, staring at the skyline like it had offended him personally.

Bumseok sidled up beside him. “Bro. Come on.”

Si-eun ignored him.

“You know she only laughs like that with you,” Bumseok said. “The rest of us? We get the polite version.”

Si-eun’s jaw clenched. “She’s clearly not saving anything for me.”

“She doesn’t know she needs to.” Bumseok nudged him. “Make a move, man. Or else Suho’s gonna do it for you.”

That got his attention.

Si-eun turned sharply. “He wouldn’t.”

Bumseok just gave him a look. “He could.”

And that was enough.

Later, when everyone had left and Y/N lingered behind to help clean up, she found him still on the rooftop, alone.

“You okay?” she asked softly.

He didn’t turn around. “Why wouldn’t I be?”

“You barely said a word all night.”

He finally glanced over, eyes unreadable. “Maybe I didn’t have anything worth saying.”

Y/N frowned. “Did I do something?”

Silence.

And then—

“You were hanging on Suho the whole night.”

She blinked. “...I was?”

“Don’t play dumb.”

Y/N tilted her head. “Are you mad about that?”

His mouth twitched. “I don’t get mad.”

“You get moody.”

She stepped closer, eyes narrowing. “You’re jealous.”

He didn’t deny it.

Instead, Si-eun finally turned fully to face her, eyes dark. “I don’t like seeing other people touch what I want.”

Her breath caught. “What you want?”

He stepped closer, gaze intense. “You.”

The kiss was rough.

Not because he was angry—but because he’d been holding it back for weeks. His hands gripped her waist like he was afraid she’d vanish. Her fingers tangled in his shirt. When she gasped, he bit her bottom lip. When she whimpered, he deepened it.

When they broke apart, he didn’t move.

“Don’t let them touch you like that again,” he murmured against her mouth.

Y/N shivered. “Or what?”

“I’ll make sure they know who you belong to.”

They didn’t sleep that night.

She ended up pressed against his chest, her thighs trembling around his hips, his mouth buried against her throat as he groaned her name into the dark. And when she came, shaking under him, she whispered: “I’m yours.”

And that was all it took to undo him.

The next morning, Si-eun walked into the living room, looking half-wrecked but smug.

Y/N followed ten minutes later, limping slightly.

The boys didn’t miss a thing.

Suho: raises a brow “Sleep well?” Bumseok: snorts into his cereal Ryu: blinking “Why is Y/N walking funny?”

Y/N flushed bright red.

Si-eun didn’t say a word. Just leaned back in his chair, crossed his arms, and stared down Suho with the most smug, satisfied glare in the world.

Let them guess.

He didn’t need to say a thing. He had what he wanted.
