JEONG JAEHYUN (정재현) — TWISTED (18+)
✧
the apartment was quiet, save for the gentle hum of the air conditioning and the rhythmic sweep of the mop across the floor. you moved with practiced precision, your hands gliding over every surface with meticulous care. a flick of your wrist here, a light dusting there—small adjustments that hardly seemed worth noting, but they were. every movement had a purpose, even if it was hidden beneath the veneer of tidying up.
the soft afternoon light filtered through the curtains, casting a warm glow over the room. you wiped down the windowsill, straightened the framed photo of you and jaehyun on the shelf with a smug glint in your eyes, and smoothed out the creases in the bedsheets. the apartment, as always, was immaculate, the kind of clean that only came from constant upkeep. but today, the cleaning wasn’t really about cleanliness. it was about preparation.
you paused by the desk, fingers brushing over the cool surface. between the neatly arranged pencil holders and stacks of paperwork, you slipped in a small camera, positioning it just right. a subtle angle, nothing too obvious, but enough to capture every corner of the room. a second camera followed, this one hidden in the far corner, tucked away in the shadows where it wouldn’t be noticed. satisfied, you moved on.
under the bed, you placed a voice recorder, pressing it firmly against the wood, ensuring it was out of sight. there was no room for mistakes, not today. finally, a tiny bug nestled into the corner of the room, blending seamlessly with the décor. you stepped back to admire your work, a slight smile tugging at the corners of your lips. everything was in place.
with a slow, deliberate movement, you tightened the belt around your dress, the soft leather pulling snug against your waist. the fabric draped perfectly, as it always did, every detail considered, every piece of you in control. you reached for the bottle of perfume on the vanity, its familiar scent filling the air as you dabbed it on your wrists. not your favorite scent—his. the one that made him lean in just a little closer, his breath catching for just a second longer.
you adjusted the microphone headset over your ears, the cool metal brushing against your skin. a sip of wine followed, the rich, dark liquid swirling in the glass before you took a slow, savoring taste. the tension in your muscles melted away, replaced by something else, something darker. not stress, not weariness, not betrayal. no, none of those things. what filled you now was a quiet thrill, a heat that coiled low in your stomach, simmering beneath the surface.
without a second glance, you made your way downstairs, the soft click of your heels echoing in the hallway. the receptionist barely looked up as you approached, her hand sliding instinctively to the desk drawer. you slipped her a bundle of cash—thick, well-prepared, without a word exchanged. she nodded, her hand moving to unlock the door behind her. you stepped inside the dimly lit security room, the soft hum of the monitors filling the space around you.
you settled into the chair, your fingers tracing the edge of the wine glass as you watched the screens flicker to life. one by one, the angles of the apartment room came into view, each camera displaying its silent feed. and there he was, as you knew he would be. jaehyun, standing in the corner, his body pressed against someone else. a woman, her legs wrapped around his waist, her arms clinging to his back. their lips moved in a frantic, fevered kiss, bodies entwined as if the world outside ceased to exist.
your eyes lingered on the screen, a slow, satisfied smile creeping across your face as you sipped your wine. typical. the scent of your perfume must have hit him, because his movements stilled for just a moment, nostrils flaring as he pulled back from the kiss. but it didn’t matter. even now, with another woman in his arms, your presence haunted him. and that, more than anything, sent a wave of satisfaction through you.
he pressed her harder against the wall, his fingers tangling in her hair, lips grazing her neck. but you didn’t flinch. you didn’t feel the sting of jealousy, didn’t feel your heart shatter at the sight. instead, there was a sick, twisted pleasure in watching him repeat the same motions he did with you. It should have hurt—should have torn you apart—but it didn’t. if anything, it thrilled you.
there was something captivating in watching his desire, watching him pour himself into someone else, knowing full well that no matter how much he took from her, it would never compare to what you gave. he could try, he could chase that feeling, but it would never be the same. not without you. so you let him have his time. let him indulge. and as you sipped your wine, watching the scene unfold before you, you knew that he would always come back. because no one else would ever match what you had.
the security room was dim, the glow of the monitors casting an eerie light over jaehyun’s sharp features. he sat in the worn leather chair, eyes glued to the flickering screens before him. the scent hit him first, thick and sweet like spun sugar, relentless in its sweetness, clinging to every breath he took. your perfume. it was unmistakable, coating the air with a syrupy heaviness that curled around him like a possessive hand. he grunted softly, his fingers gripping the arms of the chair, knuckles whitening as he inhaled deeply, letting the scent overwhelm his senses.
he knew it too well. the fragrance that lingered on your skin after a night out, the same one that would pull him toward you, that made his breath hitch when he buried his face in your neck. but tonight, the thought gnawed at him. was it for him? the way it used to be? or for your lover, the one you disappeared with after slipping out of the apartment when you thought he wasn’t looking?
the lines blurred in his mind, the sharpness between you and him, between you and whoever else had stolen your time, stolen what should have been his. his jaw tightened as he leaned closer to the screen, eyes narrowing. you had set this up. he knew it the moment he stepped into the room, knew it from the way the cameras were positioned. it was so you—calculated, precise, cruel in a way only he could appreciate. he wanted to hate it, to hate you, but instead, a twisted admiration crawled up his spine. this was your game, and he was only too willing to play.
his eyes roamed over the grainy image as you finally appeared on the screen, your figure unmistakable even through the static. you stepped into view, your dress clinging to your body like it was made for you, and jaehyun’s breath hitched again, the scent of your perfume still assaulting his senses. his hand, almost unconsciously, moved to his lap, the tension in his body easing slightly as he spread his legs wider, trying to alleviate the growing ache. but you weren’t alone.
his teeth grazed his bottom lip as he watched, every muscle in his body going rigid as a man stepped into the frame behind you. tall, unfamiliar, hands that gripped you too familiarly, lips that ghosted over the curve of your neck with an urgency that made jaehyun’s skin prickle. the man’s mouth moved against your skin, bruising and licking, leaving marks that jaehyun knew too well—the kind that staked a claim. his pulse quickened, his body reacting before his mind could catch up, a satisfied hiss slipping from his lips. he hated it, the way he was drawn to the sight of you with someone else. hated the way his body responded, the way his fingers twitched to touch the screen, to feel connected to something—anything—that involved you.
dd it feel the same? did the man know what you liked, the way jaehyun did? the way your breath caught when lips hovered over your collarbone, the way your back arched when fingers tangled in your hair. the possessiveness that burned in his chest was primal, instinctual. you were his, even if the world around him screamed otherwise. and then, just for a second—a fleeting moment that almost slipped past him—you paused. your head tilted, and your eyes, dark and knowing, flicked upward. they locked onto the camera. jaehyun’s breath hitched. you knew.
for a moment too long, your gaze didn’t waver. that smirk—the one he had memorized, the one that had undone him more times than he cared to count—curled at the edges of your lips. you weren’t just aware of him. you were showing him. every movement was deliberate, every arch of your neck as the man kissed your skin, every glance toward the lens, every shift in your posture. it was all for him. the realization hit him with the force of a train. this wasn’t about the man with you. he was just a prop, a tool in your hands to provoke the reaction you wanted.
jaehyun exhaled slowly, the tension in his body turning into something else—something deeper, darker. his lips parted, and he muttered under his breath, barely above a whisper, “that’s my girl.” the words felt raw, scraping against his throat, filled with a kind of pride that he hadn’t realized he still held. you knew him too well. better than anyone. you played him like an instrument, each note of your performance calculated to draw out exactly what you wanted from him. and he couldn’t help but admire it, as twisted as it was.
he leaned back in the chair, legs still spread wide, his hand dragging down his face as he let out a slow, steadying breath. his eyes never left the screen, watching as the man pulled you closer, his hands disappearing into your hair, mouth claiming yours in a kiss that should have made jaehyun see red. but he didn’t. he couldn’t. because in that moment, he knew it didn’t matter. none of them mattered.
the way the man touched you, the way he kissed you, it would never come close to the way jaehyun did. he knew you in ways that no one else ever could. you might share your body with someone else, but your mind, your games—they were all his. you left breadcrumbs, and he followed them willingly, drawn into the labyrinth you’d created. another smirk tugged at the corner of his lips as he watched you, his girl, wrapped in another man’s arms, knowing full well you’d never belong to anyone else but him. he would let you play your game, let you dance with whoever you wanted, but in the end, it would always come back to the two of you.
he adjusted his seat, the sick heat of satisfaction settling deep within him. he couldn’t look away from the screen, even if he wanted to. and why would he? you were performing for him, after all. “knows me so well,” he murmured again, his voice a low, reverent sigh as he let his hand drop to his side. his eyes darkened, pupils dilating as he watched you, watched the man touch you, watched you steal glances at the camera. always for him.
the apartment was quiet again, but this time the silence was different—thicker, charged, as if the air itself was holding its breath. you felt it in the way your pulse raced beneath your skin, in the subtle tremor in your fingers as you stood in the middle of the room. he wasn’t far behind. you could hear him, the soft sound of his footsteps growing louder, closer, until the door clicked open behind you. you didn’t turn around. you didn’t need to. you could feel him watching you, his gaze heavy and possessive, the tension between you winding tighter with every passing second.
jaehyun didn’t say a word as he moved closer, the heat of his body pressing against your back. his hands slid around your waist, fingers grazing your hips before traveling upward, the soft fabric of your dress bunching under his touch. his lips found the side of your neck, the same spot where the man’s had been just hours earlier, but jaehyun’s kiss was rougher, more demanding. he bit down lightly, eliciting a sharp gasp from your lips, and you could feel him smirk against your skin.
“you must’ve seen us, yeah?” your voice was breathless, words slipping out between shallow pants as his hands tightened around your waist, pulling you flush against him. he answered with a low, guttural groan, the sound vibrating against your neck as his mouth moved lower, assaulting your skin with hot, open-mouthed kisses. his breath was ragged, uneven, and you felt the hardness of him pressing against the back of your thighs through his boxers, straining against the fabric. the memory of what he had seen—of you with another man—was still fresh in his mind, fueling every touch, every kiss.
jaehyun’s hand slipped under your dress, fingers trailing down to your panties, and without hesitation, he pushed them aside, his fingers finding the wet heat between your legs. his thumb brushed over your clit, slow at first, teasing, before he began to rub in tight circles, his pace quickening as he leaned into your ear. “every bit of it,” he murmured, his voice low and rough, sending a shiver down your spine. “you gave it to him real good, baby.”
a smirk tugged at your lips as you twisted your fingers into his hair, yanking his head back just enough to force him to look at you. his lips were swollen, glistening with spit, and his eyes—those dark, dangerous eyes—were filled with lust and something darker, something unhinged. you’d always loved that look, the way it made your heart pound, the way it made your core ache for him.
without warning, you slapped him hard across the face, the sharp crack of skin against skin reverberating through the room. the force of it left his cheek red, and the sting of your palm lingered in the air. jaehyun’s lips parted in a shocked gasp, his pupils blown wide as the lust in his eyes deepened into something feral. his hand flexed at your waist, and for a moment, you thought he might lose control completely. instead, he groaned, a low, broken sound that made your stomach clench, and you could feel his cock twitch against you, his boxers impossibly tight. “almost like you expected less of me,” you purred, your voice dripping with satisfaction as you traced the red mark on his cheek, watching the way his breath hitched at your touch. you could feel the power shift between you, feel the way his body reacted to your every word, your every movement.
he didn’t respond with words. instead, his hands moved to your shoulders, shoving you back onto the bed with enough force to make the mattress creak. you let out a sharp moan as your body hit the sheets, your back arching as jaehyun climbed on top of you, his weight pressing you down. he grabbed your wrists, pinning them above your head as his lips trailed down the curve of your neck, past your collarbone, before they found their way to your breasts.
he groaned as his mouth latched onto one of your nipples, sucking hard, his tongue swirling over the sensitive bud. his other hand cupped your breast, squeezing, kneading, as if he couldn’t get enough of them. “love these so much,” he murmured against your skin, his voice muffled by the fullness of your breast in his mouth. “the other girls, they don’t have ones like this.”
your breath hitched, the praise sending a wave of heat through your body, making your knees weak. but before you could process it, jaehyun released your wrists and leaned up, his hand moving with brutal swiftness as it collided with your cheek in a stinging slap that made your head snap to the side. the sharp pain bloomed across your skin, and instead of recoiling, you moaned, the sound desperate and raw, your body arching toward him in a way that begged for more. “i don’t get to play with them like this,” he smirked, his thumb brushing over your reddened cheek before trailing back down to your chest, his hands claiming your breasts again as if they belonged to him.
your thighs clenched around his waist, hips bucking up against him, desperate for friction, for relief from the ache that had been building inside you from the moment he touched you. his name slipped from your lips in a breathless whisper, a plea that made his smirk widen as he pressed his body down against yours, his erection rubbing against your bare thigh through his boxers. he leaned down, capturing your lips in a bruising kiss, his tongue sliding against yours with a hunger that felt primal, unhinged. the kiss was messy, spit slicking your lips as his hands moved down your body, fingers curling around the waistband of your panties before he yanked them off in one rough motion. his fingers returned to your core, probing and rubbing, and every touch was calculated to make you squirm, to elicit the moans he’d missed on camera.
you broke the kiss to gasp for air, your head tipping back as he slid two fingers inside of you, curling them just right, hitting the spot that made you see stars. your legs trembled around him, every nerve in your body lit up with need as he pumped his fingers in and out of you, his thumb pressing against your clit in time with each thrust.
“god, jae,” you gasped, your fingers gripping his hair, tugging hard enough to make him groan. He loved when you pulled his hair, loved the sting of pain mixed with pleasure. “yeah,” he grunted, his voice low and ragged as he looked up at you, his fingers never slowing. “you like it when i watch, don’t you? see how desperate you are for them.”
you smirked, your body arching off the bed, chasing the pleasure. “i like it when you can’t stop yourself,” you breathed, your voice thick with desire. “when you’re so addicted to me, you can’t even think straight.” his eyes darkened, the intensity of his gaze sending a shiver through you as he pulled his fingers from you, leaving you empty and aching. in one swift motion, he shoved his boxers down, his erection springing free, hard and desperate for you. he didn’t hesitate, grabbing your hips and yanking you down the bed before positioning himself between your legs.
he hovered above you for a moment, eyes locked onto yours, the air thick with tension, before he thrust into you, filling you in one hard stroke that knocked the breath from your lungs. you cried out, nails digging into his shoulders as your body adjusted to the sudden fullness, the burn of the stretch only intensifying the pleasure. he groaned, his head falling to your shoulder as he set a brutal pace, his hips slamming into yours with a desperation that bordered on madness. the room was filled with the sounds of skin slapping against skin, of his ragged breaths and your breathless moans, of the bed creaking under the force of his thrusts.
he buried his face in your neck, biting down hard enough to bruise as he fucked you with reckless abandon, his body shaking with the force of it. you clung to him, your legs wrapped around his waist, your body moving in perfect sync with his, lost in the intensity of the moment, lost in the feeling of him inside of you. jaehyun’s hands moved down to your chest, gripping your breasts with a hunger that made your breath hitch. his fingers dug into the soft flesh, squeezing, kneading, his eyes glued to the way they moved with each hard thrust of his hips. he was obsessed, completely entranced, as if he couldn’t get enough of the way they filled his hands, the way your nipples stood hard and ready for him.
his mouth descended on one of them, his lips hot and wet as he sucked greedily, swirling his tongue around your sensitive nipple before biting down gently, just enough to send a sharp jolt of pleasure through your body. you moaned, your back arching off the bed as his teeth grazed your skin, leaving a red mark in his wake. he groaned against your breast, his hand moving to cup the other one, his thumb flicking over your nipple, sending shockwaves of pleasure straight to your core.
“fuck, i love these,” he repeated between kisses, his voice thick with lust, muffled by your skin as he continued to lavish attention on your chest. “they’re so fucking perfect, baby. none of the others—” he paused, his teeth grazing your nipple again, harder this time. “—none of the other girls have tits like this.” you smirked at his words, your breath coming in ragged gasps as you threaded your fingers through his hair, yanking him up to meet your gaze. his lips were wet, spit running down his chin, his eyes wild with need, the dark desire in them so potent it made your stomach flip.
“good,” you panted, your voice breathless but teasing, “because they don’t deserve them.” his cock twitched inside you at that, and you knew you had him. he liked when you reminded him, when you made him see that no matter who he was with, no matter what he did, you were the one he couldn’t let go of. you were the one who owned him.
you ran your hands down his chest, your nails scratching lightly against his skin, leaving faint red lines in their wake. he groaned at the sensation, his hips stuttering slightly as he thrust into you harder, deeper, chasing the release he knew he’d only find with you. “i saw you, you know,” you whispered, your voice thick with a twisted kind of admiration. “you fucked her so well, jae. i was impressed.”
his breath hitched at your praise, and you could feel the way his body responded to your words, the way his cock swelled inside you, twitching with need. his grip on your breasts tightened, his hips slamming into yours with renewed force as if he was trying to prove something, trying to show you that no matter who he fucked, it was you that he belonged to. “yeah?” he groaned, his voice low and rough as he leaned down, his mouth hovering over yours. “you liked watching me fuck her?”
you moaned in response, your legs tightening around his waist as you lifted your hips to meet his thrusts. “yeah,” you breathed, your lips brushing against his, teasing him. “but you know what i like even more?” he growled, his hand slipping from your chest to your throat, his fingers wrapping around your neck as he pressed his lips to your ear. “what?”
“i like knowing that no matter how good it was, no matter how hard you fucked her, you always come back to me,” you whispered, your voice dripping with confidence, with satisfaction. he groaned at your words, his hand tightening around your throat just enough to make your breath catch. “fuck, baby,” he muttered, his voice thick with desire. “you’re the only one. no one else feels like this.”
he leaned down, his mouth crashing against yours in a bruising kiss, his tongue sliding against yours in a wet, messy tangle of spit and need. you could taste him—taste the desperation, the hunger that only you could satisfy. his lips were swollen, raw, and you kissed him harder, your fingers digging into his hair, pulling him closer. he pulled back slightly, his breath hot against your lips as he looked down at you, his eyes dark and filled with a primal kind of lust. “you like it when i fuck them, huh?” he babbled through a haze of lust, his hips slamming into yours again, his pace relentless. “you like knowing that no matter how good they are, they’ll never be you.”
you moaned in response, your nails digging into his back as your body trembled beneath him. “yes,” you panted, your voice barely more than a whisper, “because they’ll never be enough for you.” jaehyun’s hand moved from your throat to your breast again, squeezing it roughly as he leaned down, his lips trailing down your neck to your chest. he sucked on your nipple, his tongue swirling around it before pulling it between his teeth and biting down, hard enough to make you cry out in a mix of pain and pleasure.
“god, i love these tits,” he groaned, his voice muffled by your skin. “could fuck them all day.” your legs trembled, the intensity of his words and the roughness of his touch pushing you closer to the edge. you could feel the coil of pleasure tightening in your stomach, ready to snap at any moment. “then do it,” you teased, your voice breathless as you arched into him. “fuck me like you fuck them, jaehyun. show me.”
his eyes flashed with something dark and devious, and without warning, he pulled out of you, leaving you empty and aching. you barely had time to protest before he grabbed your hips, flipping you onto your stomach with a rough shove. you moaned as your body hit the mattress, your hands gripping the sheets as he positioned himself behind you. he didn’t waste time. his hands gripped your ass, spreading you open as he thrust into you from behind, the force of it making you cry out, your body jolting forward with each hard thrust. the angle was different, deeper, and you could feel every inch of him as he slammed into you, his cock hitting the spot that made you see stars.
his hand came down on your ass with a sharp slap, the sting of it sending a wave of pleasure through your body. “fuck,” you gasped, your voice muffled by the pillow as your hips bucked back against him. “harder.” he growled, his fingers digging into your hips as he fucked you harder, faster, the sound of his skin slapping against yours filling the room. “you really love this, don’t you?” he grunted, his voice low and rough. “love knowing i fuck them, but i come back to you.”
you moaned, your body trembling with pleasure as you nodded, your words coming out in broken gasps. “yes, yes, i love it.” his hand came down on your ass again, harder this time, and you cried out, the sting of it mixing with the overwhelming pleasure building inside you. “good,” he muttered, his voice thick with lust. “because this is the one thing i get to do that they can’t.”
with that, he thrust into you one last time, his body tensing as he buried himself deep inside you, his cock pulsing as he came, filling you with hot, sticky heat. you moaned at the feeling of him cumming inside you, the sensation sending you over the edge as your own orgasm ripped through you, your body convulsing with pleasure. jaehyun collapsed on top of you, his chest heaving as he pressed soft kisses to the back of your neck, his hands still gripping your hips tightly. “this,” he murmured against your skin, his voice soft but possessive, “this is mine.”
