Whispered Sins

-Hyungwon-

Inspired by Secrets by Monsta X

The clock ticked past midnight, the city alive with noise and lights outside your window. But in your apartment, silence pressed down like a secret too heavy to hold. You hadn't expected him tonight—not after his warning last time—but something in you had known he wouldn't stay away.

The lock clicked. A low hum of anticipation ran through you before you even turned.

Hyungwon leaned against the doorframe, shadows carving sharp lines across his face. His coat hung half-open, the faintest smirk tugging at his lips, but his eyes burned dark and hungry.

"You keep telling me not to come back," he said, voice smooth but laced with danger, "but you never mean it."

You should have pushed him away. You should have reminded him that if anyone found out, both of you would shatter under the weight of the fallout. Instead, your breath hitched, betraying you.

He caught it. He always did.

In two long strides, he was in front of you, his fingers sliding up your arm, slow and deliberate, leaving heat in their wake. He pinned you gently against the wall, his mouth ghosting dangerously close to yours.

"You're poison," you whispered, though your body arched toward him.

His laugh was low, sinful. "Then drink me in."

The kiss was not gentle—it was fire, hunger, a collision that stole every coherent thought from your mind. His hands gripped your waist, pulling you flush against him, his body a wall of heat and restrained need. You tasted desperation, tasted the risk in every clash of lips and teeth.

He broke the kiss just long enough to press his lips to your ear, his voice a dark caress. "Do you know what you do to me? I should hate you for it... but I can't stop."

Your nails dragged across his shirt, desperate to touch skin, to claim something forbidden. He caught your wrist, smirking, holding it above your head while his free hand slid down your thigh, the pressure enough to make you shiver.

"Every time I tell myself this is the last time," he murmured, eyes locked on yours, "and every time, I crave you more."

The air was thick with lust, but beneath it, a thread of something softer tugged at you—a raw honesty in his gaze, the unspoken truth that this wasn't just about desire. It was about needing you in a way neither of you could explain.

His lips crashed back onto yours, deeper, rougher, and in that moment, nothing outside those walls mattered. Not the world, not the risk. Just him. Just you. Just the secret that bound you together like sin you'd willingly commit again and again.

His mouth devoured yours, the kiss rough and claiming, like he was trying to etch himself into you. You barely had time to breathe before his tongue slid against yours, coaxing, demanding, sending sparks down your spine.

Pinned to the wall, your body melted against him, every nerve alight under his touch. His hand still held your wrist above your head, dominance laced with the gentlest restraint, while his other hand skimmed under your shirt, fingertips tracing your skin like he was memorizing every inch.

You gasped when his palm cupped your breast, thumb brushing over your nipple through the thin fabric. The sound made his lips curve against yours in a dark smile.

"Sensitive," he murmured, voice husky, his breath hot against your cheek. "I like that."

Your protest caught in your throat when he pushed your shirt up and lowered his mouth, lips closing around your nipple, sucking until your knees weakened. You moaned, arching into him, and his grip on your wrist tightened just enough to remind you he had control.

"Hyungwon—" His name escaped on a desperate breath, more plea than word.

He looked up, eyes heavy with lust but softened at the edges, something raw flickering there. "Say it again," he ordered softly.

"Hyungwon."

The way you said his name seemed to unravel him. He released your wrist, only to slide his hand down, dragging it across your body until he reached the waistband of your shorts. His lips returned to yours as his fingers slipped inside, parting you easily, teasing at your slick folds.

You gasped into his mouth, clinging to his shoulders as he stroked you slow, deliberate, making you writhe against the wall.

"Already so wet," he whispered against your lips, voice dripping with desire. "You've been waiting for me."

You hated how true it was.

When his fingers slipped inside you, curling just right, your head fell back, a broken moan escaping. He kissed down your throat, sucking marks into your skin as his rhythm grew faster, wetter, his thumb circling your clit until you were trembling.

"You're mine like this," he growled softly against your neck, "no one else gets to see you fall apart."

The words struck something deep inside you—possessive, dangerous, but laced with a tenderness he couldn't hide. You wanted to tell him he was yours too, but the words tangled with your cries as he pushed you higher and higher.

Your release tore through you suddenly, your body clenching around his fingers, your voice breaking on his name. He held you through it, kissing you fiercely, swallowing every sound like it was his lifeline.

When you finally sagged against him, shaking, he rested his forehead against yours, breathing hard. His fingers still glistened with your slick, but his eyes—dark, wild—were softened by something more.

"You undo me," he whispered, almost like a confession. "And I'll keep coming back... even if it destroys me."

You kissed him again, slow this time, full of the words neither of you dared to say out loud. And in the heat of that secret night, it was enough.

Your body was still trembling when Hyungwon pulled his fingers from you, his gaze locked on yours as he slowly brought them to his lips and sucked them clean. The act was sinful, devastatingly beautiful, and it made heat pool low in your stomach all over again.

"Bedroom," he ordered softly, but it wasn't a request.

You barely managed a nod before he scooped you up effortlessly, carrying you down the hall. The world blurred until he laid you down on the bed, his tall frame looming over you, eyes burning like he was starving.

His mouth was on yours again in an instant, kissing you deep, desperate, while his hands tugged your shorts and panties down in one smooth motion. He broke the kiss only to strip his shirt away, and you couldn't help but stare—broad shoulders, defined lines of muscle, pale skin flushed with heat.

You reached for him, pulling him down until his body pressed against yours, the hard length of him straining against his pants. He groaned into your mouth when your hips arched up, grinding against him.

"You're driving me insane," he rasped, teeth grazing your bottom lip. "I can't wait anymore."

His pants and briefs were gone in seconds, and then he was pressing against your entrance, the thick head of his cock sliding through your wetness, teasing, making you whimper.

"Please," you begged, nails digging into his shoulders.

That was all he needed. He pushed inside slowly, stretching you, filling you inch by inch until you were gasping, clinging to him. His forehead pressed against yours, a guttural moan slipping from his throat.

"Fuck... you feel perfect," he whispered, voice breaking on the word.

He gave you a moment, kissing you softer this time, before pulling back and thrusting in again—deeper, harder. The rhythm built fast, his hips snapping against yours, the bed creaking with every movement. You wrapped your legs around his waist, pulling him closer, meeting every thrust with your own.

The pace was rough, unrelenting, but beneath it was something more—his hand sliding down to lace with yours, his lips pressing kisses to your jaw, your temple, like he needed to mark you everywhere.

"Say it's mine," he demanded between thrusts, his voice raw.

"It's yours," you cried out, the words torn from you, truth spilling in the heat of it all.

His thrusts grew wilder, his moans mixing with yours, the room filled with the sound of skin against skin and ragged breaths. His free hand gripped your thigh, holding you open for him as he drove deeper, hitting the spot that made stars burst behind your eyes.

Your climax hit hard, body arching, clenching around him as you screamed his name. Hyungwon cursed, burying his face against your neck as he thrust a few more times before shuddering, spilling inside you with a broken groan.

For a long moment, neither of you moved, just tangled bodies and heavy breaths, the air thick with sex and something unspoken.

Finally, he lifted his head, hair plastered to his forehead, lips swollen, eyes dark but achingly vulnerable.

"This isn't stopping," he whispered, voice rough but steady. "I can't stop. Not with you."

You reached up, brushing your thumb across his cheek, and felt the weight of your own truth pressing out of you. "Then we don't stop. Ever."

His lips crashed onto yours again, but this kiss was different—less frantic, more certain. A seal. A promise.

Whatever the cost, whatever the risk... there was no going back.
