────────── ୨ৎ───────────

His room is dead quiet, except for the occasional scratch of a pencil against paper and the soft click of a highlighter cap.

You’re on his bed, sprawled on your stomach, watching the back of his neck like it’s your newest obsession.

Si-eun hasn’t looked at you in almost an hour.

He’s been glued to that textbook, surrounded by notes so color-coded it’s like staring into a disciplined rainbow.

And he still hasn’t taken a break.

You prop your chin on your hand

“You’re gonna fry your brain if you keep staring at that,” you say, voice lilting.

“I’m fine” he says flatly.

Another highlight. Another note.

You roll onto your back, stretching. Loudly.

Nothing.

Ugh this guy, he really chose to study over his partner who was on his bed!

Then with a hum you sit up, slide off the bed, and walk over to where he’s seated at his desk, a mischievous plan forming in your head.

“You’ve been studying for three hours.”

You said with a whine

“I need to memorize the entire structure by Friday.”

He replies dismissively, his eyes trained on his notes

“Then I guess I should help you… focus.”

You said with a sly grin, sauntering toward him with a spark of mischief in your eyes—each step part of a plan you knew he wouldn’t like.

That gets a reaction. A small pause in his hand, barely a flicker. But you see it.

You lean down behind him, gently wrapping your arms around his neck, lips grazing his ear while your chest tantalizingly pressed against his back.

“Or would that be too distracting?”

His back stiffens — not fully, just enough to let you know you’ve hit the target.

“Yes,” he says, still staring at his notes.

“Oh no,” you cooed mockingly, “am I ruining your perfect concentration?”

Your fingers trail down his collar bone— light. Lazy.

His jaw tenses.

Still, he says nothing.

Jeez, he’s stubborn.

So you slide onto his lap.

He doesn’t stop you — but he doesn’t look at you either. Just freezes beneath you, breath caught, eyes closed and a deep sigh escaping his lips.

You knew you where slowly getting under his skin

“I’m bored,” you pout, rocking slightly. “Can’t you take a small break at least?”

He grips the edge of the desk tighter.

You lean close again, voice low and teasing.

“You’re really gonna pretend you’re not hard right now?”

That’s it.

The lead in his mechanical pencil snaps against the paper after he pushes down too hard.

He still doesn’t look at you.

But something inside him snaps, the next second, he’s gripping your waist pulling you closer, pressing your body down against his — and yeah, you were right. He’s hard. Painfully.

“You think this is a game?” he growls quietly, but rough, and nothing like his usual flat tone.

Your smirk fades just a little.

“You’ve been teasing me for weeks. Walking around like you don’t know what you’re doing to me. Saying things like that in my ear—”

His hands grip on your waist now slipping beneath the fabric, grounding, almost shaking.

“—and you expect me to just sit here and study?”

He finally looks at you.

His eyes are darker than you’ve ever seen. A little glassy, a little desperate. Like he’s starving.

“Si-eun—”

~smut starts here~

“Shut up.”

You gasp softly as he pulls you into a rough kiss — not angry, but hungry. His lips move over yours like he’s trying to make up for every second he held back.

Si-eun's lips move demandingly against yours, his tongue pushing past your parted lips to claim your mouth. It's not gentle, but it's not cruel either. It's urgent, desperate, a silent plea for release from the constant torment of wanting.

His hands slide down to your thighs, gripping them tightly as he opens your legs wider and pulls you closer, pressing your core harder against the thick ridge of his erection straining against his pants.

He breaks the kiss abruptly, his chest heaving as he stares at you with eyes that burn into yours.

"Is this what you wanted?" he asks, his voice low and rough. "To see me like this? To make me lose control?"

His hips flex upward, grinding his hard length against your aching center. The friction makes you gasp, your head falling back.

"Because this is what you're doing to me, y/n. You're driving me crazy."

His hands slide up your sides, pushing your shirt out of the way to expose your chest. His palms cover them, thumbs brushing over the hardened peaks.

"I can't think straight. I can't focus. All I can think about is you. touching you. tasting you."

He leans in, his lips brushing the sensitive skin of your neck as he speaks, his breath hot against your flesh.

"Isn't this enough of a break for you?" he asks, his voice a low, seductive murmur. "Aren't you satisfied with how much you've affected me?"

His fingers pinch your nipples, rolling them between his fingers. His hips grind against yours, the ache between your legs growing with each movement.

"Tell me, y/n," he says, his voice a low, demanding growl. "Tell me you want this too. That you need this as much as I do."

With uneven, ragged breaths, you let out a shaky plea.

“I need you, Si-eun… I want you,” you whispered, voice thick with desire.

Your body trembled beneath his touch, arousal pooling hot and heavy beneath your underwear as he continued to tease—fingers skillfully toying with your hardened nipples, drawing out soft, helpless gasps you couldn’t hold back.

Si-euns eyes darkened further at your breathless admission, his grip tightening on your waist. A shudder ran through his lean frame at your words, his control fraying by the second.

In a flash, he stood, easily lifting you with him. He swept the books and papers off his desk with one arm, not caring where they fell. Then he gently laid you down on the edge, stepping between your parted thighs.

His fingers hooked into the waistband of your pants and underwear, with one sharp tug, he yanked them down your legs and off.

He drank in the sight of you, sprawled out before him, your chest heaving and your skin flushed. His gaze was hungry, almost feral, as it raked over your naked body.

"y/n..." he breathed, his voice rough with need. "You have no idea what you do to me."

He leaned down, his lips brushing over your stomach, your ribs, the mound of your chest. His tongue flicked out, tasting your skin, tracing the curves of your body like he was mapping out every inch of you.

His fingers slid higher, teasing along the inside of your thigh, tracing the delicate skin there. Higher and higher, until his thumb brushed over your private area, making you jolt and gasp.

He looked up at you then, his eyes blazing into yours. "I'm going to make you feel so good, y/n," he promised, his voice low and intense. “I'm going to give you everything you've been teasing me for."

And with that, he leaned down and put his mouth on you, his tongue sucking and licking your wet private part, twisting and teasing, driving you wild with pleasure. His fingers on the other hand pumped inside you, curling and thrusting, stroking all the right spots.

He didn't hold back. He gave you everything, just like he'd promised. And as your cries of ecstasy filled the room, he just kept going, determined to make keep his word.

Si-eun felt your body tense, heard the hitch in your breath, and knew you were close. He doubled his efforts, his tongue swirling around your private part, sucking hard as his fingers pumped faster, deeper, driving you towards your peak.

When your climax hit, it was with a cry of his name, your voice echoing off the walls of his bedroom. Your body convulsed, your inner walls clenching tight around his fingers as your sweet nectar gushed out, coating his lips and chin.

Si-eun didn't pull away. He kept licking, kept suckling, helping you ride out the intense waves of your orgasm. He savored the taste of you, the feel of your body trembling against him, your pleasure a headier drug than any study could ever be.

Only when your trembling subsided did he finally pull back, his eyes lifting to meet yours. They were dark and satisfied, a small, smug smile playing at the corners of his mouth, glistening with your essence.

"Si-eun..." you gasped out, still trying to catch your breath. "That was... incredible..."

He stood up, wiping his mouth with the back of his hand. He looked down at you, his gaze intense and hungry, his pants still straining obscenely.

"I'm not done with you yet," he said, his voice a low, seductive promise. "That was just the beginning."

He reached for the button of his pants, popping it open and unzipping his fly. He shoved his pants and underwear down, freeing his aching cock. It sprang out, long and hard and thick, the head an angry red.

Si-eun took himself in hand, stroking it slowly against your cunt as he looked down at you. "I'm going to take you now, y/n," he said, his voice a low, intense growl. "I'm going to make you mine in every way possible."
