This work contains mature themes, MINORS DO NOT INTERACT!!
======================================
He should’ve stopped himself from looking.
But Hyunjin had barely registered the clingy fabric of your black gown before he’d started spiraling. The shape of your waist, the way the skirt hugged your hips like they were made for you—and your makeup, god. It was barely even there, but it enhanced everything in a way that had him swallowing down the desire to ruin you.
Your eyes met his across the hotel lobby. And even from where you stood, you caught the way his throat bobbed.
“Stop staring,” you mouthed to him, hiding your smirk.
But Hyunjin just shrugged, his jaw tight as he held your gaze. He wasn’t planning to stop. Not anymore.
You stepped into the elevator with your friends, and Hyunjin was right behind you. His hand grazed your back as you shuffled forward to make room, and he leaned in close, voice low near your ear.
“You wore this on purpose, didn’t you?”
You didn’t look at him. “Wore what?”
“This,” he whispered, eyes dropping to the way your shirt curved along your body. “You knew we’d run into each other.”
You smirked. “You’re the one who invited me.”
“And you’re the one who didn’t say no.”
The elevator jolted slightly as it started its ascent, the air thick with unspoken tension. One of your friends called your name, trying to show you something on her phone, but you barely processed it. Hyunjin was behind you—right behind you—and you could feel the heat radiating off him like a second skin.
His hand brushed your lower back again, lingering this time.
“Do you want him?” he asked, his breath ghosting against the shell of your ear.
Your head tilted slightly. “Who?”
“That guy. The one who picked you up earlier from the office.”
You let out a soft laugh, not even trying to hide the taunt in your tone. “Are you jealous?”
Hyunjin’s hand slid lower. Just enough to make you press your thighs together.
“Answer the question,” he said, voice sharp.
You turned your head just enough to glance at him over your shoulder. “I didn’t know you cared.”
“I don’t,” he lied. “I just think it’s pathetic. Showing off for someone who doesn’t even know how to touch you right.”
Your breath hitched. The elevator doors slid open.
But for a second, neither of you moved.
Your friend tugged your wrist, breaking the moment, and you stepped out of the elevator with a shaky exhale. Hyunjin followed, his presence looming behind you like a stormcloud.
The hall was already half-full when you walked in. Music pulsed low from a speaker in the corner, and conversations buzzed around the room. You tried to focus on the people greeting you, the drinks being passed around, the laughter—but it was impossible to forget the way Hyunjin’s eyes stayed glued to you, even from across the room.
He hadn’t stopped looking. Not once.
You could feel it. That heat, that pressure, like he was touching you without even moving. And god, it was messing with your head.
You grabbed a drink from a passing waiter and sipped slowly, trying to steady yourself.
But Hyunjin came up beside you like gravity, pulling you right back under.
“You’re ignoring me now?” he said, voice smooth but dark at the edges.
You glanced at him, feigning boredom. “I’m just trying to have fun.”
His eyes flicked to the drink in your hand. “That why you keep running?”
“I’m not running.”
He leaned in, his mouth dangerously close to your ear. “Then why haven’t you looked at me since we got here?”
You stayed still, refusing to give him the satisfaction of flinching. “Because you’re being dramatic.”
Hyunjin let out a low, humorless laugh. “You think I don’t see what you’re doing?”
Your lips curled. “And what am I doing?”
He didn’t answer.
Not with words.
His hand brushed yours lightly—deliberately—as he reached for a second drink. His fingers barely grazed your skin, but it sent a jolt up your arm like he’d grabbed your wrist and pinned you against the wall.
You swallowed hard.
He smirked. Like he knew.
“Keep playing games,” he murmured, stepping back. “Let’s see how long you last.”
And just like that, he melted into the crowd again, leaving you breathless and burning.
⸻
You didn’t last long.
Maybe it was the music, or the alcohol finally hitting, or the way Hyunjin always seemed to be exactly where your eyes landed. Maybe it was the unbearable heat crawling beneath your skin from pretending you didn’t want him all damn night.
You needed space.
Your friend had wandered off, distracted by some conversation you didn’t care to follow. So you slipped away, fingers grazing the edge of your glass as you made your way towards one of the private ensuite bathrooms.
The moment the door shut behind you, relief hit. The noise of the party dulled.
But you weren’t alone for long.
You didn’t have to turn around to know who had followed.
Hyunjin’s presence was unmistakable. The click of the door. The silence that followed.
“Couldn’t stay away, huh?” you muttered, keeping your eyes on the mirror.
“Neither could you,” he said. “You left just when it was getting interesting.”
You turned, slowly, and there he was—leaning against the doorframe, his tie loose around his neck like temptation incarnate. That same cocky glint in his eye, but softer now, like he was toying with something delicate. Dangerous.
“This is a work event,” you reminded him. Yourself.
He smirked. “Then you probably shouldn’t have looked at me like that in the conference room this morning.”
“You were the one staring.”
“You wore that damn skirt.”
You rolled your eyes, but your breath caught when he stepped forward—just enough for you to feel the heat of him.
“Tell me you don’t want this,” he said, voice low. “Tell me and I’ll walk away.”
You could’ve. You should’ve.
But instead, you looked up at him—his lips parted, eyes dark, breathing just a little too hard—and didn’t say a thing.
And that was all he needed.
He kissed you like it was inevitable.
There was nothing soft about it. It was all teeth and tongue and months of pent-up frustration from stolen glances and snide remarks and pretending you didn’t feel the way you did.
You shoved him back into the wall with a gasp, fingers curling into his jacket. He gripped your hips like he’d waited forever to do it.
Maybe he had.
Maybe you had too.
You were the one to break the kiss.
Barely.
It took everything in you to pull away, your lips tingling, breath uneven, heart hammering so loudly you swore he could hear it.
“You don’t get to do that,” you breathed, stumbling back a step, your fingers trembling as you wiped your lips. “You can’t just kiss me like that—”
“Can’t I?” he murmured, his eyes still locked on your mouth like he was starving.
Your back hit the sink counter, the cool porcelain a jarring contrast to the heat in your veins. “This isn’t happening,” you whispered, almost to yourself, trying to calm the tremor in your voice. “We’re at a work event, Hyunjin.”
He chuckled under his breath, low and dangerous. “So? It’s not like they’ll come looking for us in the bathroom.” His body moved closer, boxing you in.
“I’m serious,” you snapped, hands flat against his chest, though you didn’t push him away. “We need boundaries. This can’t happen”
He cocked his head. “Then why aren’t you pushing me?”
You froze.
His hands slid down to your hips. “Why are you still letting me touch you, hmm?” His lips brushed your ear. “Why are your thighs clenched right now like you’re trying to hold something in?”
“Hyun—”
“I can prove it,” he whispered, voice like velvet, sinfully soft. “I can prove you want this just as much as I do.”
Before you could answer, you heard it—footsteps. Voices, too close for comfort, echoing just outside the door.
Your breath hitched.
And in that moment of panic, he seized his chance.
He turned you swiftly, pressing you back against the tiled wall with a quiet thud. One of his hands slipped beneath your dress, hiking it up as his other pinned your wrists above your head.
“You’re soaked,” he hissed, fingers ghosting over your panties. “You’re going to tell me that’s not for me?”
Your gasp came sharp, stifled, your head knocking softly against the wall as his fingers pressed against the thin lace between your legs.
“Hyunjin—” It was supposed to be a warning. It sounded like a plea.
“You’re trembling,” he whispered, mouth dragging down the column of your neck, teeth grazing the pulse hammering in your throat. “Your body’s begging me. Why are you still pretending?”
You wriggled in his hold, but it wasn’t to escape. You hated how right he was. How your knees were already buckling and your core pulsed under his barely-there touch. “We’ll get caught,” you tried, voice cracked. “You need to stop—”
“But you don’t want me to.”
He let your wrists go just long enough to shove your panties aside, sliding two fingers through your slick folds with practiced ease. The hiss he let out was pure, filthy satisfaction.
“Fuck—look at you,” he murmured. “Dripping, and I’ve barely touched you.”
Your hands flew to his shoulders, nails digging in as he circled your clit, slow and teasing, dragging out your agony. You hated how your hips tilted toward him, like your body had a mind of its own.
The voices outside the door got louder. Someone laughed, and you jolted.
Hyunjin didn’t stop.
In fact, he smirked.
“You’re scared they’ll hear,” he murmured. “But I bet that turns you on, doesn’t it? Knowing I’ve got you pinned and desperate with just my fingers—while anyone could walk in.”
His fingers pushed inside you, and your breath caught so sharply you almost choked on it.
“Oh my god—” You slapped a hand over your own mouth, eyes wide with panic and pleasure as he fucked you slow, deep, deliberate. “Hyunjin, please—”
“You want me to stop?”
You didn’t answer. Couldn’t.
“That’s what I thought.” His thumb found your clit again, pressure devastating, rhythm perfect.
Your legs were shaking now, thighs trembling against his hips as he whispered filth into your ear, all while the risk of getting caught grew louder outside that thin bathroom door.
“You’re gonna cum for me just like this, baby,” he whispered. “Then you’re going to look me in the eye and admit you’ve wanted this for months.”
You barely managed to stifle the sound that tore out of your throat as Hyunjin curled his fingers just right—deep, deliberate, fucking devastating. The squelch of your soaked cunt echoed in the tight, tiled space, and you clamped a hand over your mouth, eyes wide in alarm.
Then came the knock.
“Is someone in there?”
Your blood ran cold. That voice. It was your friend.
Hyunjin froze—only for a breath.
Then he smirked.
“Occupied,” he answered smoothly, no hint of guilt, no shame in his voice.
“Have you seen y/n anywhere?” your friend asked casually, her voice muffled through the door. “She kind of disappeared on me.”
You locked eyes with Hyunjin, shaking your head frantically, lips pressed together to keep from whimpering.
He raised a brow—then sank to his knees.
No. No. No—
You slapped your hand harder over your mouth as he shoved your skirt higher around your waist, lips finding the inside of your thigh as he stared up at you like a man possessed. You mouthed his name, warning him, begging him, cursing him all at once.
But Hyunjin only grinned against your skin.
“She’s around,” he called through the door, deceptively calm, eyes never leaving yours. “Maybe try outside?”
Your friend hummed. “Alright. Thanks.”
Footsteps.
They faded.
But you couldn’t breathe.
Because at the exact moment the footsteps disappeared, Hyunjin dove in.
His tongue licked a slow, obscene stripe up your folds before closing around your clit, moaning low like you were his favorite fucking meal. His fingers stayed buried, fucking you through the heat building far too fast, while his mouth claimed you with such ruthless focus it made your knees buckle.
You almost sobbed behind your hand.
He didn’t let up. If anything, he doubled down—groaning into you, sucking greedily, alternating between messy circles and tight flicks that made your whole body jerk.
You were going to cum.
And he knew it.
He curled his fingers again and whispered against your pussy, “Say it. You want this just as bad as I do. Say it, baby.”
But you were too far gone.
And he knew that, too.
You tried. God, you tried so hard not to fall apart. But Hyunjin didn’t give you a fucking chance.
He never once broke eye contact as his tongue moved with expert cruelty—slow and deep, then fast and dizzying, as if he needed your orgasm on his tongue, like it was the only thing that could satisfy him. Your hand gripped his hair like a lifeline, the other still clamped over your mouth, muffling the guttural, trembling sounds escaping you.
“Don’t fight it,” he murmured, breath hot and wet against your cunt as he slipped his fingers in deeper. “I feel how close you are. Just give it to me, baby…”
He knew you would.
He wanted to ruin you.
And fuck, you let him.
Your legs trembled violently, and before you could stop it, your hips jerked forward—grinding shamelessly against his mouth like you were starved for it, like he was the only thing that could ever make you feel this full, this high, this completely fucking gone.
The orgasm hit you like a damn explosion.
White-hot. All-consuming.
You gasped so loudly your own hand wasn’t enough to muffle it. Your thighs clenched around his face as your whole body spasmed, and Hyunjin groaned like he was the one cumming, his mouth never leaving you, tongue relentless as he coaxed out every last wave of your release.
He didn’t stop until you were literally sliding down the wall, boneless and wrecked, your mind somewhere between heaven and hell.
Only then did he rise, slow and smug, licking his lips like a fucking devil.
“You taste better than I imagined,” he whispered, pressing a kiss to your cheek, then your jaw, then finally your lips—letting you taste yourself on him.
You were too dazed to respond. Too wrecked to fight.
And Hyunjin… he looked like he was just getting started.
You tried—God, you tried to push him away, even if your limbs barely responded. Even if your body, traitorous and trembling, leaned into his every touch.
“Hyunjin, s-stop,” you breathed, but it sounded more like a plea than a command. “We can’t—”
He caught your wrists mid-protest and raised a brow, lips brushing your jaw with a dark promise. “No?” he said lowly, “You were begging for it a second ago.”
And then he turned you around—swift, decisive—and bent you over the sink before your gasp could leave your throat.
Your hands slapped against the cold porcelain, the mirror catching your dazed reflection. Your mouth hung open, your lipstick smeared, your eyes wide with something feral. You barely recognized yourself.
“Look at you,” Hyunjin growled behind you. “Still dripping for me even after coming on my fingers. Still pretending you don’t want this.”
He dragged your panties down with zero patience, letting them fall around your thighs before hiking your dress over your hips. You squirmed instinctively, shame crashing over you—but it only made him groan.
“Stop pretending,” he hissed, lining himself up behind you. “I feel how much you want this.”
You whined as the head of his cock nudged your entrance, your mind screaming for control but your body melting for him.
You gripped the edges of the sink as he pressed in—slow, thick, unforgiving—stretching you open inch by inch until you felt full in a way that made you ache. He leaned over you, chest pressed to your back, one hand sliding around your throat as he whispered into your ear:
“You should’ve set those boundaries before I had my fingers buried in you.”
Then he snapped his hips.
You cried out.
Hyunjin didn’t let up—not when you clenched around him, not when your knees buckled, not when your whimper twisted into a moan that you barely managed to bite down. His thrusts were rough, precise, punishing.
“I should ruin you,” he breathed, “right here. Make it so you can’t even walk out of this room without everyone knowing what we did.”
Your reflection was flushed and falling apart, lips parted around a silent cry, tears gathering at the corners of your eyes. You hated how good it felt. You hated how you didn’t want him to stop.
And he knew it.
You barely held yourself up, your hands slipping on the sink, breath fogging up the mirror as Hyunjin rutted into you like a man possessed. Your legs trembled with every drag of his cock inside you, slick and obscene. He kept one hand fisted in your hair and the other tight on your waist, grinding his hips into you like he didn’t care who was outside—
Knock knock knock.
You both froze.
“Hyunjin?” your friend’s voice called again from the other side of the door. “Someone said they saw her come in here… is she with you?”
You didn’t even have time to react—Hyunjin didn’t stop. If anything, his thrusts got slower. Deeper. Cruel.
“Yeah,” he answered, perfectly calm, the words steady even as he fucked you through them. “Occupied.”
“Is she with you?” she asked again, a little more curious now.
Hyunjin’s lips brushed the shell of your ear as he fucked into you harder, more deliberately, making you arch and writhe and bite your hand to keep from screaming. Your friend was right there. Right there.
“She’s not feeling well,” he said, voice dipped in that honeyed charm, breathless but convincing. “I’m helping her.”
You nearly sobbed at the irony. Helping you? You were barely able to stand.
Your friend hesitated behind the door. “O-oh. Okay. Just—hurry. People are starting to ask.”
“Got it,” he called back—then slammed into you with enough force to knock the breath from your lungs. You made a choked noise, and he chuckled darkly against your shoulder.
“You like this way too much,” he whispered. “Look at yourself. Trying to stay quiet while I fuck you full.”
Your knuckles turned white from how hard you gripped the sink. Tears slipped free. You wanted to say stop—but your walls kept fluttering around him, gripping him like you never wanted him to leave.
And Hyunjin knew it.
“You’re dripping down my cock,” he murmured. “Don’t lie to yourself again.”
You whimpered, utterly ruined, unable to hold anything back anymore.
Hyunjin’s breath stuttered against your neck as his pace grew erratic, needy—his cock pulsing deep inside you with every thrust. He grabbed your hips harder, like he was trying to keep himself grounded, but you could feel him unraveling behind you, barely holding on.
You felt it too—the crash coming fast.
“Fuck—‘m gonna—” his voice broke, groaning through gritted teeth. “Gonna cum inside you, baby, I have to—I can’t pull out—”
You nodded, dizzy, boneless, body screaming yes even when your mouth couldn’t form the word.
Just when you thought your friend had walked away, the hall quiet again, you lost control—your orgasm hitting like a violent wave. You clamped around him, gasping his name out loud—
“Hyunjin—!”
That’s all it took.
With a low growl, he buried himself fully, hips flush against your ass as he spilled deep inside you. His hands trembled on your body as he held you close, both of you shaking, your moans echoing around the tiled walls like a secret you couldn’t keep.
For a moment, neither of you moved. Your breath fogged up the mirror again. His forehead dropped to your shoulder.
Then, as your legs threatened to give out completely, Hyunjin helped you stand. You both scrambled to fix your clothes, clean what you could, and make yourselves at least look normal. You smoothed down your dress. He ran a hand through his hair. Your heart was still pounding.
You reached for the door.
Cracked it open.
And there she was.
Your friend. Standing just a few feet away. Arms crossed. Lips curled into the smuggest smirk.
“Feeling better?” she asked sweetly.
You opened your mouth. Closed it. Hyunjin appeared behind you, cool as ever.
“Yeah,” he said before you could speak. “She’s all good now.”
You wished the floor would open and swallow you whole.
“Well, well, well,” she said, her tone sing-song and a little too smug. “Took you long enough. Was the bathroom line that long?”
You froze. She smirked.
“You’re glowing, babe. Real suspicious behavior.”
You tried to laugh it off. “Shut up.”
“Oh, I will,” she said, linking arms with you like nothing was out of the ordinary. “Just as soon as you stop walking like your knees forgot how to work.”
You groaned, burying your face in your hands as she giggled and dragged you back toward your table.
The rest of your friends were already chatting, none the wiser. You sank into your seat, praying the heat in your face would die down before he showed up. But of course, the universe had other plans.
Hyunjin arrived two minutes later—cool, composed, not a single hair out of place. Like he hadn’t just bent you over a sink and fucked the life out of you. Like he didn’t still have your body trembling under the table.
Your friend caught the way your eyes flicked up the moment he sat across from you. She leaned over just enough for you to hear, voice low and gleeful.
“Damn. You’ve got guts.” She whispered. You elbowed her under the table.
“I’m just saying,” she whispered again. “Bathroom breaks don’t usually come with afterglow.”
You hissed her name, and she snickered, reaching for her drink.
Hyunjin, across the table, tilted his head and met your gaze. He raised a brow. Then, without breaking eye contact, he lifted his glass to his lips and took a slow sip, the corner of his mouth curling up like he could hear every word.
You sank a little lower in your seat.
Your friend didn’t look at him—didn’t have to.
“You’re gonna be real quiet all night now, huh?” she said just loud enough for you to hear. “Wonder why.”
Hyunjin finally looked away, joining the table chatter like nothing happened.
But under the table, your thighs pressed together, heartbeat in your throat, and the ache between your legs still whispered his name.
