Jungkook is the professor. YN is the student who stays too late after class and leaves with the kind of marks that need long sleeves the next day. They are not dating. They are not anything that can be named in daylight. 

They are the thing that happens when the office door locks and the blinds are already down—clothes half-off, mouths rough, bodies using each other like the only honest language either of them has left. Intense. Physical. No soft edges. 

He fucks her like he’s trying to carve something permanent into the temporary, and she takes it like she already knows the expiration date is built in.

He wanted to own her. Not just fuck her—own her. He wanted to put his teeth in her neck in the middle of a crowded hallway and dare anyone to look at her twice. He wanted to claim her so brutally that the whole damn campus would know she belonged to him. But he couldn't. It was a sick, useless fantasy. If he opened his mouth, it would blow up in their faces. He’d lose his job. She’d get kicked out. Everything ruined for what? To stroke his own ego?

So he kept his mouth shut. He choked down the possessiveness. He settled for leaving bruises on her thighs in the dark and pretending it was enough.

Until he saw her in the courtyard.

The sun was too hot. The concrete was glaring. Jungkook was just cutting across the campus to get back to his office when he stopped dead in his tracks.

She was sitting at a stone table. Not alone.

Some nameless, stupid kid from her study group was sitting right next to her. Their thighs were practically touching. But it was the kid's hand that made Jungkook’s blood turn to ice. The boy had his hand resting flat on her lower back. Right at the dip of her spine. Right over the spot where Jungkook had left red welts with his own grip just twelve hours ago.

And then YN laughed.

It hit him like a punch to the gut. It wasn’t a gasp. It wasn’t a dirty, desperate whine. It wasn't the ragged noises she made when he was tearing her clothes off. It was a soft, unguarded laugh. It was bright. Easy. She was looking at this kid with soft eyes, just talking, just smiling.

She never looked at him like that.

With Jungkook, it was always rough. It was biting and scratching and hiding in the dark. But with this boy, she was giving away pieces of herself in broad daylight for free.

A sick, black wave of jealousy slammed into his chest. His jaw locked. He stared at that boy’s hand on her back and pictured walking over there. He pictured grabbing the kid by the hair, dragging him off the bench, and snapping his wrist over his knee. The image burned into his skull. It was so loud in his head he could almost hear the bone crack.

But he didn’t move.

He just stood there in the heat, his hands balled into tight fists in his pockets, his knuckles white. He stood far enough away that she couldn’t see him, letting the ugly, violent sickness take root in his gut. He watched another man touch her. He watched her smile at it.

He didn't step out into the light. He didn't say a word. He just turned his back on them and walked away.

But the damage was already done. The jealousy was in his blood now, black and boiling, just waiting for the door to lock behind them tonight.

The rest of the day was a total blur of meaningless academic garbage. Jungkook spent three different lectures staring blindly at a whiteboard, completely checked out, listening to his own voice drone on while his brain just replayed a looped, suffocating reel of that hand on that waist. He snapped at two grad students. He nearly crushed a piece of chalk to powder. By the time his last office hour finally ended, his nerves were frayed so thin a strong breeze could have snapped them.

Then came the routine. The pathetic, careful little routine.

He waited two blocks off-campus, idling his bike in the damp alleyway behind a closed convenience store like a total creep. Right on time, there she was. Slipping out of the shadows, sliding onto the leather seat behind him, completely oblivious. She dragged the helmet over her head, wrapped her arms tight around his waist, and pressed her smiling face into his back, assuming everything was perfectly fine.

It wasn't. He was boiling alive in his own skin.

They tore down the street, weaving through the late afternoon gridlock. The wind was whipping past them, the engine vibrating beneath their thighs. YN’s hands were flat against his stomach, holding him tight. But every time he felt her touch, all he could feel was that flat-faced kid's hand replacing hers.

He slammed on the brakes as they hit a red light at a crowded, grimy intersection. Exhaust fumes hung thick in the air, cars idling aggressively on all sides of them.

Jungkook planted his boots on the asphalt. He flipped up the visor of his helmet, turning his head just enough so his voice would carry over the low, heavy rumble of his engine.

"So," he shouted back, his tone dripping with a lazy, venomous sarcasm that didn't quite mask the crackle of absolute rage underneath it. "Who's the charity case?"

YN leaned forward, her chest pressing flush against his spine, trying to hear him over the noise of the traffic. "What?"

"The kid from the courtyard!" Jungkook yelled, his voice laced with a crude, mocking edge. He kept his eyes locked on the red light, gripping the handlebars until his knuckles turned white. "The one who looked like he forgot how to breathe through his nose. Are you running a tutoring service for the socially inept now, or does he just genuinely think staring at your chest is going to help him pass the midterm?"

Behind him, YN blinked, her hands loosening on his jacket for a second as confusion set in. "Are you talking about Minho? We're partnered up for the macro-economics project! We were just going over the data sets!"

"Data sets. Right," Jungkook let out a harsh, patronizing bark of a laugh that cut right through the street noise. He tilted his head back further, making sure she could see the nasty smirk painted on his mouth in the side mirror. "Is that what they're calling it these days? Because from where I was standing, it looked like his primary research was figuring out the exact curvature of your lower back."

He revved the engine once, loud and obnoxious, before dropping his voice into a filthy, condescending sneer. "Tell me, did he actually contribute to the project, or did you just let him cop a feel out of pity? I know you have a soft spot for strays, but letting a kid grope you in broad daylight just seems a little... cheap. Even for you."

The silence that followed was entirely internal, drowning out the honking cars and the mechanical roar of the street.

Jungkook waited for the shame to hit her. He expected her to shrink back on the seat. To stutter out a defensive excuse.

Instead, YN’s grip on his jacket tightened so hard her nails dug through the heavy leather. The confusion vanished instantly, replaced by a cold, glittering fury. She didn't shrink away. She leaned in even closer, pressing her helmet right against his shoulder, her mouth practically brushing his ear.

"Cheap?" she laughed, a dry, hollow, biting sound that scraped straight down his spine. "That's rich, coming from the guy who makes me wait by a dumpster like a fucking drug deal just so he can get his rocks off."

Jungkook's jaw locked so hard his teeth ground together.

"But you know what?" YN practically spat the words into his ear, her voice terrifyingly steady and entirely unbothered. "You're right. He did have his hand on my waist. And you want to know the best part, Professor? His hand wasn't even shaking."

She shifted her weight on the bike, dragging her hands slowly from his stomach up to his chest, mocking the possessiveness he was trying to weaponize against her. "He touched me in front of three hundred people, Jungkook. In the middle of the courtyard. In the literal sunlight."

He opened his mouth to snap back, but she cut him off, her words precise and merciless, stabbing into every single raw, bleeding nerve he possessed.

"Maybe if you weren't such a pathetic coward, so terrified of your precious little tenure committee, it could have been your hand," she sneered, the sheer venom in her tone burning hotter than the exhaust pipe. "But you can't do that, can you? You want to act like you own me behind locked doors, but the second the sun comes up, you don't even have the balls to look me in the eye in the hallway. So yeah. I let him touch me. Because unlike you, he actually looks at me like he wants me in public, and not just like some dirty, shameful little secret he has to bury in the dark."

The traffic light snapped from red to green. The cars around them started to move, horns blaring as Jungkook stayed perfectly still, entirely paralyzed by the sheer violence of her words.

YN tapped her fingers mockingly over his racing heart, shouting her final, brutal blow over the roaring traffic. "So if you're done throwing a little bitch fit over a boy who actually has the spine to claim what he wants... are you going to drive this fucking bike, or should I just walk back and call him?"

For a split second, Jungkook didn't move. He just sat there, letting the absolute sheer audacity of her words ring in his ears, a dark, dangerous heat flooding his vision.

Then, he laughed. It wasn't the patronizing scoff from earlier. It was a low, unhinged vibration that rumbled deep in his chest.

"Oh, yeah?" he taunted, his voice dropping an octave, turning rough and ugly. "You want to go back and call him, huh? You think that flat-faced virgin even knows how to handle a girl who likes it as filthy as you do?"

He gripped the throttle and revved the engine, a deafening, violent roar that drowned out the traffic around them. "You think he knows how to choke you out, YN? You think he knows how to make you beg? You have no fucking idea what you're doing right now. Keep pushing me, and you're going to find out exactly what happens when you cross the line."

But YN wasn't intimidated. The adrenaline was already spiking in her veins. Instead of shutting up, she leaned in even closer, practically climbing over his back. She pressed her lips right against the sliver of exposed skin at the nape of his neck, her voice dropping into a breathless, mocking whisper.

"What's wrong, Professor? Are you jealous?" She trailed a gloved finger down his chest, feeling his muscles lock up to the point of snapping. "Does it make you sick, Jungkook? Thinking about someone else putting his hands on what's yours? Does it bother you that another man might touch what's been under you every night?"

That was it. The absolute breaking point.

Jungkook dropped the clutch. The bike jerked forward with neck-snapping force, but instead of taking the route toward her apartment, he banked hard. He tore across the intersection, tires screeching against the asphalt as he whipped the bike aggressively in the exact opposite direction.

YN gripped his waist, her stomach dropping as they blew past a yellow light. "Where are we going?" she yelled over the wind.

He didn't answer. His jaw was set in stone, his eyes black and hollow in the rearview mirror. He just pushed the bike faster, weaving recklessly through the thinning traffic, taking sharp turns down increasingly darker, narrower streets.

"Jungkook! Where are we going?!"

Total, suffocating silence.

He didn't slow down until they hit the industrial district, pulling into a dead-end alleyway behind a row of abandoned, graffiti-covered warehouses. It was pitch black, completely isolated, hidden from the street by rusted dumpsters and chain-link fencing.

He slammed on the brakes. The bike skidded slightly on the loose gravel before he kicked the stand down and killed the engine. The sudden silence in the alley was deafening.

Before YN could even unbuckle her helmet, Jungkook was off the seat.

He didn't say a word. He just grabbed the sides of her helmet, unclipped it roughly, and yanked it off her head, tossing it onto the pavement with a hollow clatter. The second it was off, his hand shot out. His fingers tangled ruthlessly into the thick, wavy lengths of her hair, gripping the heavy strands right at her bra-strap line, and yanked her off the bike.

She gasped, her hands flying up to grip his wrist, but he was already spinning her around. With one violent, seamless motion, he shoved her down, bending her over the leather seat of the motorcycle. Her chest hit the warm metal of the gas tank, her breath knocking out of her lungs.

Jungkook didn't give her a second to recover. He crowded in right behind her, his chest caging her back, his hand still fisted tightly in her long, bleached hair, pulling her head back just enough to expose her throat.

"Call him," Jungkook barked, his voice a guttural, feral snarl right against her ear, devoid of any of his usual control. "Go on, YN. Where's your phone? Call him right now."

He pressed his hips flush against hers, pinning her flat against the bike, his other hand sliding violently down her ribs to grip the exact spot on her lower back where that kid had touched her. His fingers dug into her waist, bruising and possessive.

"You think he can give you this thrill?" he demanded, his breathing heavy and ragged, the venom pouring out of him. "You think some stupid kid with a textbook can make you shake the way I do? Huh? You think he can make you feel the way I make you feel when I have you bent over like this?"

He yanked her hair a fraction harder, forcing her to arch her spine against him, entirely consumed by the violent, territorial sickness he had been trying to suppress all day. "Tell me you want him to touch you now. I fucking dare you."

"You can't be serious," she gasped, her voice trembling just enough to betray the absolute chaos racing through her veins. "You want me to call him? Right now?"

Jungkook didn't flinch. A dark, mirthful glint flashed in his eyes, illuminated only by the distant, sickly yellow glow of a streetlamp bleeding into the alley. The anger from the ride was still there, boiling just beneath the surface, but now it was morphing into something infinitely more dangerous: cold, calculated possessiveness.

"Dead serious," he murmured, his voice dropping to a smooth, lethal register. He leaned in, the rough leather of his jacket scraping against her back. "Go on. Pull out your phone. Tell him you need help with the data sets. Isn't that what you were doing? Keep it normal. Keep it friendly. Like you aren't bent over my bike in a dark alley."

"Jungkook, no—"

And within a second, their position changed. 

He kept her folded over the motorcycle like something he’d already broken in and planned to break again. Chest crushed to the warm curve of the gas tank, cheek turned against the leather, ass shoved high and open for him. 

The alley stank of old oil and wet concrete. Distant traffic hummed like background static. Jungkook’s body was a solid wall behind her—chest to her spine, one boot braced between her feet to keep her thighs spread, fist locked in the heavy fall of her hair so tight her scalp already burned.

His cock was a thick, heavy ridge trapped behind the black denim of his jeans, grinding slow and filthy against the seam of her pants. 

Not thrusting. Just rolling. Deliberate. The hard head dragged right over her clit with every pass, fabric-on-fabric friction that made her cunt clench and flutter like it was trying to suck him in through the clothes. 

She was already soaked. She could feel the slick heat spreading, the way her panties had gone from damp to completely ruined, clinging to every swollen fold.

His mouth returned to her neck while he spoke—open, wet, sucking hard enough that she felt the blood rush up under the skin. He was marking her. Leaving proof. The thick ridge of his cock never stopped grinding, slow and heavy and clothed, every roll of his hips dragging that denim-covered head right over her throbbing clit. Her pussy was already pulsing in empty, desperate little squeezes. She could feel herself getting wetter by the second, the slick heat turning thick and slippery between her thighs.

“I can’t,” she whispered, voice cracking on the word. “I don’t— I don’t want to be filthy while I’m talking to him. Jungkook, please—”

His fingers dug into the welts already painted across her lower back. The pressure was precise and mean, right on the tender purple marks he’d left the night before. Pain bloomed hot and bright and shot straight down into her cunt. She hissed. A fresh gush of wetness soaked through her thong; she felt it happen, the fabric going from damp to completely slick and heavy in seconds. Her clit was swollen and aching, every tiny shift of her hips making the soaked material drag over it like a dirty little punishment.

“Either you call him,” Jungkook said against her ear, calm as anything, “or I leave you unattended right here. Pants down. Dripping. Alone in the dark with your cunt throbbing and nothing to fill it. Your choice.”

A broken little sound escaped her. Half whine, half sob. Her pussy was clenching so hard it hurt—empty, aching, so wet she could already feel the slick starting to trickle down the inside of one thigh. She could smell herself. Thick and musky and shameless. She hated how desperate it made her. Hated how her body was already begging for whatever filthy thing he was about to do.

Her hand shook when she pulled the phone from her back pocket. The screen lit her face in cold blue light. Minho’s name sat in her recent calls like an accusation. Jungkook’s mouth never left her skin—jaw, the soft place under her ear, the side of her throat—kissing, biting, licking the marks he was leaving while she unlocked the phone with trembling fingers. His cock kept grinding, slow and relentless, the hard head rubbing right against her clit through the layers of fabric until she was biting the inside of her cheek to keep from moaning.

She hit call.

It rang twice.

“YN?” Minho’s voice was easy, a little surprised. “Hey. Everything okay?”

Jungkook’s hips rolled forward again, slow and filthy. The thick, clothed length of his cock pressed right against her through the denim, grinding in a tight circle that forced the seam of her pants to drag over her swollen clit. Her mouth opened on a silent gasp. She had to swallow twice before she could speak. Her cunt was throbbing so hard she could feel her heartbeat in it.

“H-hey. Yeah. I’m— I’m good.” Her voice wavered on the last word. Just a little. Just enough that she felt Jungkook’s mouth curve into a smirk against her neck.

Minho’s tone shifted. “You sure? You sound kinda… off.”

Jungkook’s fingers left the welts on her back and slid lower. He cupped her between the legs through her jeans, whole hand covering her, heel of his palm pressing firm against her clit, fingers curling under to feel how hot and wet she’d already made the fabric. He didn’t rub. He just held. Owned. The pressure was constant and merciless. She bit the inside of her cheek so hard she tasted copper. Her pussy clenched hard against his palm, another thick pulse of slick soaking through the denim.

“I’m fine,” she managed. The words came out thinner than she wanted. “I just— I was going over the data sets again and I got stuck on the regression for the second variable. Can you— can you walk me through how you calculated the coefficient again?”

Jungkook’s mouth curved against her neck. She felt the smirk. His free hand left her pussy only long enough to pop the button of her jeans and drag the zipper down. The sound was obscenely loud in the quiet alley. He shoved the denim past her hips in one rough push—not all the way off, just far enough that the cool night air kissed the bare skin of her ass and the tops of her thighs. Her thong was a thin black string between her cheeks, the front panel already dark and heavy with her slick. He hooked two fingers under the soaked gusset and yanked it aside.

The wet sound was filthy.

Her cunt was dripping. The slick had soaked completely through the thin fabric, glossy and sticky, stretching in clear strings when he pulled the thong clear of her folds. He made a low, approving noise against her throat and dragged the pad of one finger through the mess, just once, collecting it. Thick. Gooey. The kind of wet that meant her body was already past ready and deep into desperate.

“Fuck,” he breathed, so quiet only she could hear. “Look at that. Gooey little cunt. You’re dripping down your own thighs and he doesn’t even know. Soaking your thong like a filthy secret.”

She had to answer Minho. Her voice shook.

“I— I think I messed up the lag variable. Can you check the numbers I sent earlier?”

Minho started talking, easy and helpful, walking her through the steps. Jungkook used the sound of the other man’s voice like a metronome. Every time Minho finished a sentence, Jungkook rolled his hips, dragging that thick, clothed cock against the bare, slick lips of her pussy. The denim was rough. The friction was perfect and terrible. Her clit was so swollen it felt bruised; every grind made white sparks flash behind her eyes. She could feel the head of his cock—hard, blunt, trapped behind the zipper—rubbing right over her entrance, smearing her own wetness up and down the open folds.

She was so wet she could hear it. Soft, filthy little sounds every time he moved. Slick on denim. Slick on skin. The thong string cut into one hip, pulled tight and forgotten.

Jungkook’s mouth found the side of her neck again. He bit down hard—hard enough that the pain was sharp and bright and immediate. She jerked, a tiny broken sound catching in her throat. He held the bite, sucking, marking her deep, while Minho’s voice continued in her ear, oblivious. When he finally released the skin he licked over the blooming bruise, slow and wet, like he was tasting the claim he’d just left.

“YN? You still there?”

She had to answer with Jungkook’s teeth marks burning on her neck and his cock grinding slow and heavy against her open cunt.

“Y-yeah. Sorry. Bad signal for a second.” Her voice was breathy. Too breathy. She forced it lower, softer. “Keep going. I’m writing it down.”

Jungkook’s free hand returned to the exact place on her lower back where Minho’s hand had rested. He pinched hard—twisting a little, right over the older welts—then slapped the same spot with a sharp, open-handed crack that made her whole body jolt. The dual sensation (teeth and tongue on her neck, mean fingers and palm on the bruise) made her knees buckle. Only the bike and his body kept her upright. Her cunt clenched so hard another thick pulse of wetness spilled out of her, coating the head of his clothed cock where it rubbed against her.

He whispered against her ear while Minho explained the next step, voice pure velvet filth.

“Tell him you’ll meet him tomorrow. Say it sweetly. Don’t let him hear how wet you are. Don’t let him hear how your cunt is dripping all over my jeans.”

Her thighs were trembling. Slick was running down the inside of one leg in a thin, hot trail. She could feel it cooling on her skin. Jungkook’s fingers finally moved between her legs—not rubbing her clit, not yet, just spreading her folds open with two fingers so the night air touched the swollen, shiny flesh. Every time her voice threatened to crack he went completely still—hips frozen, hand unmoving—and tightened the fist in her hair until her scalp burned and she had no choice but to breathe through it and smooth her tone back out.

“Actually,” she said, and hated how soft and sweet she made it sound, “could we… maybe go over the rest of it tomorrow? In person? I think it’ll be faster.”

Minho sounded pleased. “Yeah, of course. Library at two?”

Jungkook’s hips snapped forward once, hard, the thick head of his cock shoving against her clit through the open V of her jeans. She almost moaned. She swallowed it. Bit it down until her jaw ached. Her pussy clenched so hard around nothing that another thick rush of slick slid out of her, coating his fingers where they rested against her open cunt. He collected it on his fingertips and smeared it higher, over her clit, just pressing, not circling, letting her feel how filthy and wet she’d become.

“Two is perfect,” she managed. Her voice only wavered a little. “Thank you. Really.”

Jungkook’s mouth was still on her neck, licking the bruise he’d just made, then biting a new one an inch lower. His fingers stayed between her legs, holding her open, letting the cool air and the slow grind of his denim-covered cock torment every slick, throbbing inch of her. The thong string cut deeper into her hip. Her jeans were shoved halfway down her thighs, trapping her. She was bent over a motorcycle in a dark alley with her professor’s clothed cock grinding against her dripping cunt while she scheduled a study session with another boy in the sweetest voice she owned.

And Jungkook was smiling against her skin the whole time.

Like nothing in the world could be better than this.

He pinched the Minho-spot on her back again, hard enough to make her flinch, then slapped it once more for good measure. The sound cracked through the alley. Her cunt pulsed in answer, another helpless rush of slick sliding down to wet the leather seat beneath her. She had never felt so filthy. Or so owned. Or so close to coming from nothing but pressure and denial and the sound of another man’s voice in her ear while Jungkook ruined her in the dark.

Minho was still talking—something about confidence intervals, about checking the residual plots. Jungkook used every calm, helpful sentence like permission to grind harder. Slow. Filthy. The thick ridge of his cock dragged up through her folds, smearing her wetness all over the front of his jeans, then down again, the head catching against her entrance like it wanted to shove inside even through the fabric. Her clit was a swollen, aching point of pure need. Every time the denim scraped over it she had to bite her lip until it stung.

“You’re doing so well,” he whispered against the fresh bruise on her neck, voice almost tender. “Keeping that pretty voice so soft while your cunt drools all over my cock. He has no idea. No idea how fucking wet you get when I treat you like this.”

She had to answer Minho again. Her thighs were shaking. Slick had reached her knee.

“Y-yeah,” she said, forcing the word out smooth. “I think I see where I went wrong. Thank you. Really. I’ll— I’ll text you tomorrow to confirm the time.”

Jungkook’s fingers finally gave her clit one slow, mean press—just pressure, no rub—and she almost broke. Her voice caught. He froze instantly. Hips still. Hand still. Fist in her hair tightening until tears pricked the corners of her eyes. He waited. Patient. Cruel. Until she dragged in a breath and made her next sentence come out even and sweet.

“Talk soon, okay?”

“Yeah,” Minho said, easy and oblivious. “Talk soon.”

He didn’t let her hang up.

The second Minho started saying goodbye—easy, friendly, “Talk soon, yeah?”—Jungkook’s hand left the dripping mess between her thighs. He shoved his own jeans and boxers down in one rough shove. His cock sprang free like it had been straining against the denim the whole time, thick and heavy and already slick at the tip from how hard he’d been grinding against her. It was beautiful in the ugliest way: long, girthy, veined hard along the shaft, the head flushed a deep, angry red and already shiny with precome. It looked obscene against the pale curve of her ass, the kind of cock that stretched and claimed and left a girl walking funny the next day.

He didn’t give her a second to process it.

One single thrust.

He lined up, gripped her hip hard enough that his fingers sank into the flesh, and drove every thick inch straight into her cunt in one brutal, unbroken push. The bike creaked under them. Her body arched hard against the gas tank. The stretch was immediate and vicious—her walls forced wide around the fat head, then the veined shaft, all the way until his hips slammed flush against her ass and the head of his cock kissed the deepest part of her.

YN screamed.

Loud. Raw. Broken right down the middle.

Her free hand stabbed at the phone screen in pure panic, cutting the call dead before Minho could hear another second of it. The line went silent. The phone clattered to the gravel. She was still screaming when Jungkook hauled her up by the hair, spun her just enough, and hooked one of her legs up and over the crook of his arm so she was half-turned, forced to face him. The new angle opened her wider. He could see everything—her fucked-open cunt stretched around the base of his cock, the way her slick was already coating his shaft and dripping down onto the warm metal of the engine casing.

He didn’t start thrusting yet.

He just held there, buried to the root, and watched her face while she tried to breathe around the sudden, massive fullness.

“Look at this cunt,” he rasped, voice low and filthy. One hand stayed locked in her hair. The other braced on the gas tank, then slid down to grip her hip hard enough to bruise. “Taking every fat inch like a perfect little cock-sleeve. That kid ever get his dick inside this hole? No. He got to rest his hand on your back in the sunlight. That’s all a boy like him gets. This—” He rolled his hips once, slow and deep, dragging his cock halfway out so she could feel every vein, every ridge scraping her walls, then pushing back in just as slow until her cunt swallowed him whole again. “—this messy, greedy cunt is mine.”

He started edging her with it.

Shallow thrusts. Barely moving. The thick, red head of his cock staying inside, rubbing deliberately against that swollen front wall, then pulling almost all the way out until only the flared tip stretched her entrance open. Every time he left her empty she whined—high, desperate, the sound of a bitch in heat who hated the sudden loss of cock.

“No—no, don’t pull out—put it back in my cunt, please, I hate when you leave me empty—” Her words dissolved into broken babble the second he pushed back in, slow and deep enough to make her toes curl against the gravel. “Hate when my hole is empty, Jungkook, fuck, your cock feels too big when you drag it out, my cunt tries to suck it back in, please just stay buried—”

He caught her chin with the hand that had been on the tank, forcing her face up so she had to look at him while he fucked her in those mean, shallow strokes. His eyes were black. Possessive. Cruel.

“You’re cheap,” he said, voice almost soft, almost tender, while his cock kept teasing her open cunt. “Letting that boy put his hand on you in the middle of the courtyard like your body was free. Like any random cock could touch what’s mine.” He thrust in harder on the next stroke, burying himself to the root just long enough for her to gasp, then pulled back out until she was clenching around nothing but the swollen tip. “But look at this desperate cunt now. Only this wet, only this perfect, only this filthy and open when it’s my cock stretching it. Admit it. Say it out loud. That kid could never do this to your hole.”

Her eyes were glassy. Tears of overstimulation and pure need already gathering. She tried to turn her face away. He tightened his grip on her chin until she looked at him again.

“Say it.”

“He—he couldn’t,” she whispered, voice wrecked. “He could never fuck my cunt like this. Only you. Only your thick cock makes me this dripping wet, this—ah—this ruined—”

A voice drifted from somewhere behind the row of dumpsters. Male. Laughing. Another voice answered. Footsteps. Not close yet. But close enough that the risk was real.

Jungkook didn’t stop thrusting. He just leaned in, mouth against her ear, and kept the same slow, torturous rhythm—shallow, then almost out, then shallow again—while he spoke pure filth.

“Quiet,” he ordered, soft and deadly. “Those voices are coming from the street side. Alley’s not soundproof, baby. You keep screaming like a whore and you’re going to invite the whole fucking block over for a show.” He pushed in deep and held there, grinding the fat head of his cock against her cervix in tiny circles that made her cunt flutter. “You want that? Want them to walk back here and see you bent over my bike with my cock buried to the balls in your messy cunt? See how you’re taking it like a goddess? Drooling down your chin, thighs shaking, pussy stretched wide and shiny around me?”

Her cunt clenched hard around him at the words. A tight, involuntary spasm that dragged a low, punched-out “Fuck—” out of his own throat. He felt it. Felt how her greedy walls fluttered and squeezed like the idea of being watched had just short-circuited something deep in her fuckhole.

He laughed, dark and delighted, against her cheek.

“Oh. You like that. My dirty girl likes the idea of strangers watching her get her cunt used in an alley. Imagining it’s their hands on your hips. Their cocks taking turns stretching this dripping hole while I hold you open for them. That what you want? Public little cock-sleeve, getting filled where anyone could see? Maybe they’d stroke themselves watching your cunt cream all over my dick. Maybe they’d step closer and paint your face and tits when they finished, turn you into a sticky, glazed mess while I kept fucking this perfect hole.”

She shook her head but her body betrayed her—another hard clench, another rush of slick that made the slide of his cock obscenely wet and loud. He could hear it. The filthy, rhythmic sound of her cunt sucking him back in every time he pushed forward. Slick dripping down onto the engine hood in shiny strands.

“Answer me,” he growled, still edging her with those shallow, mean thrusts that left her hole aching and empty every few seconds. “Do you like this public humiliation, my girl? Huh? Does your cunt get wetter thinking about strangers staring at how stuffed and ruined it looks on my cock?”

“Y-yes—” The word cracked out of her on a sob. “Yes, I—fuck, I like it, I like when you talk about my cunt like that, please don’t stop filling me—”

That was all he needed.

He slammed home and stayed there, grinding deep, and her orgasm ripped through her like it had been waiting for permission. She came loud—too loud—head thrown back, mouth open on a broken cry as her cunt seized around his cock in hard, rhythmic pulses. Slick gushed out around his shaft, dripping down onto the warm hood of the engine in thick, shiny ropes. Her whole body shook. Her free leg nearly gave out. Jungkook held her up by the hair and the hip and fucked her straight through it.

He didn’t stop.

Even when she started sobbing about how sensitive her hole was—how her cunt felt too raw, too used, too stretched—he kept the same deep, relentless rhythm. Overstimulation at its finest. Every thrust punched another broken sound out of her. Her messy cunt was fluttering and clenching nonstop, trying to push him out and suck him deeper at the same time. Slick kept dripping onto the metal beneath them with every wet slap of his hips against her ass. The sound was pure filth: wet cunt, hard cock, skin on skin.

“Sensitive little fuckhole,” he muttered, almost fond, while he kept burying himself to the root. “But you love it. Listen to this greedy cunt. Still creaming all over my cock like it can’t get enough. Still trying to milk me even while you’re shaking and crying about how full it is.”

When her legs finally threatened to give out completely he pulled out—just long enough to manhandle her around and sit himself on the motorcycle seat. His cock stood up obscenely, shiny and dark and still hard as hell, veins standing out along the shaft, the head flushed deep red and coated in her slick. He dragged her into his lap, facing him, and guided her down until the fat tip kissed her ruined entrance again.

“Ride me,” he ordered, voice rough with leftover want. “You control the pace. But you keep that voice steady. No screaming. No loud little whore noises. There are still people out there. You make a sound louder than a whisper and I’ll make sure they hear exactly how wet and open your cunt is.”

She sank down onto him with a broken, wet moan she tried to swallow. The oversensitive stretch made her thighs shake. Her cunt—already fucked open and dripping—had to work to take him again. Jungkook leaned back against the handlebars like a king on a throne, hands resting lightly on her hips, eyes half-lidded and smug as hell. He looked possessive. Satisfied. Like watching her struggle to stuff her messy hole full of his cock after already coming once was the best thing he’d seen all year.

“Move,” he said.

She did.

Slow at first—rising up until only the swollen head stayed inside her cunt, then sinking back down with a shaky exhale that she tried to keep quiet. Every time the overstimulation made her falter, every time her thighs trembled and she tried to pause, his hands tightened on her hips and forced her back into rhythm. Not helping. Just guiding. Reminding her who still owned this dripping cunt even when she was the one on top.

“That’s it,” he murmured, watching her face with dark, hungry eyes. “Keep your voice nice and even. Tell me how it feels. Soft. Like you’re answering a question in class. Tell me what your cunt feels like stuffed full of cock.”

“It—it feels too much,” she whispered, trying so hard to keep the words steady while her hole fluttered and clenched around the thick intrusion. “You’re so deep like this. I can feel every vein scraping my cunt. Every—ah—every time I sit down it hits that spot and my hole tries to suck you deeper and I—”

He rolled his hips up to meet her on the next sink, just once, and her sentence dissolved into a bitten-off whimper. His hands squeezed her hips in warning.

“Steady,” he reminded her, almost gentle. “Or I stop and leave this greedy cunt empty again. And we both know how much you hate having an empty fuckhole.”

She nodded, eyes glassy, and kept moving. Rising. Sinking. Taking every long, girthy inch of him while the alley stayed dark and the distant voices drifted closer and then farther again. Jungkook watched her the whole time—watched the way her tits moved under her half-shoved-up shirt, the way her stomach flexed, the way her ruined thong still hung off one thigh and her jeans were shoved down around her knees. Watched the glossy mess of her slick coating his cock every time she lifted up, the way her cunt lips clung to him like they didn’t want to let go.

He looked smug. Possessive. Like he owned the entire filthy picture she made—open, dripping, riding his cock in a dark alley while trying not to moan loud enough to bring strangers over to watch her get used.

And when her second orgasm started building—slower, meaner, dragged out by the oversensitivity and the forced control—he just smiled and kept his hands light on her hips, letting her work her messy cunt up and down his cock while he sat there and took it like it was his due.

“Good girl,” he whispered, when her rhythm started to stutter again. “Keep going. Cream on my cock again. Show me how much this filthy hole loves being stretched and filled and owned. You’re not done until I say your cunt is done.”

Her cunt clenched around him in helpless, dripping agreement.

He didn’t pull out when he came.

He slammed in as deep as the angle would allow, hips crushing flush against her ass, and unloaded inside her like he was trying to brand her from the inside out. Thick, heavy ropes of cum erupted from his cock in hard, rhythmic pulses—flooding her cunt, painting every fluttering wall, pumping so much into her that her already-wrecked fuckhole had no choice but to take it. She felt every spurt: the wet, scorching heat of it, the way it coated her cervix, the way her greedy cunt clenched and milled around him trying to suck even more out of his balls. It kept coming—pulse after pulse of thick, creamy cum until she was overfull, until the excess started forcing its way out around the fat base of his shaft in sticky white rivulets that ran down over his balls and dripped onto the warm metal of the engine.

Jungkook stayed buried to the hilt through every last throb, grinding in lazy, possessive circles while his cock twitched and spilled, forcing his load deeper into the mess of her hole. Only when the final weak spurts faded did he ease back, slow and deliberate, watching with dark, hungry eyes as her used cunt clung to him, reluctant to let go. When the swollen, cum-slick head finally popped free with a filthy wet schlick, a thick, obscene gush of mixed cum—his heavy white load churned together with her own slick and cream—immediately poured out of her gaping fuckhole and splattered onto the engine casing in glossy ropes.

He didn’t let it go to waste.

Two fingers scooped through the overflowing mess leaking from her stretched cunt, gathering a thick, gooey smear of their combined filth—his cum, her cream, the shiny evidence of how thoroughly he’d ruined her. Then he reached around and smeared it deliberately over the exact spot on her lower back where Minho’s hand had rested in the courtyard. Right over the older bruises and welts. He rubbed it in slow, filthy circles, working the sticky white mess into her skin like a claim, like a brand, like a permanent “mine” written in cum.

“He got to put his hand there,” Jungkook murmured, voice rough and dark with leftover climax. “In the sunlight. In front of everyone. Like he had any right.” His fingers pressed harder, spreading the sticky mess. “But I’m the one who gets to put my cum on it. I’m the one who fills this cunt until it’s dripping and then marks the place he touched with what’s mine. This body doesn’t belong to anyone who only gets the daylight version of you. It belongs to the man who ruins it in the dark and then claims the evidence.”

YN’s breath hitched. She twisted enough to look at him over her shoulder, eyes wide, cheeks flushed, thighs still trembling.

“You’re insane,” she whispered. “You’re actually deranged.”

He smiled—slow, sharp, completely unrepentant—and leaned in until his mouth brushed her ear.

“Only for you,” he said. “This version of me only comes out for this cunt. For the way you take my cock like you were made for it. For the way you cream and clench and still beg for more even when you’re shaking.”

He pulled his jacket off in one smooth motion. When she reached down with shaky hands to try to drag her soaked thong back into place, he caught her wrist.

“What are you doing?” she asked, voice still wrecked.

Jungkook’s smirk was pure filth. “Trying out something even freakier with you.”

Confusion flickered across her face. He didn’t explain with words. He just swung a leg over the bike, settled into the seat like a king, and pulled her in front of him so she was facing him, straddling his lap, thighs spread wide around his hips. Both of them pulled their helmets on. Visors stayed up for now. He took the jacket and tied it firmly around her waist, knotting it tight so the dark fabric draped down over her bare ass, her open cunt, the tops of her thighs—covering the fact that her jeans were still shoved halfway down and her hole was bare, used, and actively leaking his cum. From any normal distance it would look like nothing more than a jacket tied at the waist. Only someone looking very closely—very deliberately—would catch the wet shine or the way her thighs were trembling.

“Wrap your legs around my torso,” he told her, voice cocky and calm and dripping with control. “Nice and tight. Don’t make me repeat myself.”

She obeyed, thighs clamping around his waist. The position forced her open, dripping cunt right against him. He reached between their bodies without hesitation, lined his still-hard, cum-glossy cock up against her messy entrance, and pushed back inside her in one slow, relentless thrust that forced every thick, veined inch back into the oversensitive heat of her fuckhole.

YN winced hard, a broken, punched-out sound catching in her throat as her cunt was forced to stretch around him again. “I already came—twice—hard. I can’t do it again. Jungkook, it’s too much, my cunt is raw, I can’t—”

“I’m not going to make you cum again,” he cut in, voice pure smug, cocky filth. He rolled his hips once, seating himself even deeper until his balls pressed against her, and watched her face through the open visors with dark, satisfied eyes. “You’re going to cockwarm me. That’s all. Keep this messy, cum-filled hole nice and wet and wrapped around my cock while I drive you home. You don’t get to cum. You just get to sit there with your cunt stuffed full of dick and remember exactly who put it there and who filled it. Be a good little cockwarmer and don’t you dare start squeezing like you’re trying to get off.”

Her eyes went wide behind the helmet. Fear and residual arousal warred on her face.

“There are going to be people,” she whispered urgently, voice shaking. “We can’t do this. Someone could see—Jungkook, if anyone looks too close—”

“Yeah,” he said, grinning wide and sharp, “we can.” He reached down and twisted the throttle, revving the engine once. The sudden loud, aggressive roar vibrated straight through the frame of the bike and up into the place where his thick cock was buried inside her, making her cunt flutter helplessly around him. “If you can let that boy put his hand on you in the middle of a crowded courtyard in broad daylight like a free little thing, you can take my cock on this bike while I give you a ride home. Public for public. He got to touch your back in the sun. I get to keep my dick soaking in your cum-stuffed cunt through the entire city. Fair’s fair, baby.”

He flipped his visor down. She did the same, fingers trembling. Then he kicked the stand up, twisted the throttle harder, and the bike surged forward out of the dark alley with a deep, throaty growl.

The engine’s vibration was constant and filthy. Wind immediately whipped past them as he merged into the thinner late-evening traffic, cool night air cutting across their bodies. Every bump in the road, every shift of gears, every lean into a turn drove his thick cock fractionally deeper or dragged the ridged shaft against her sensitive, overstretched walls. She was so wet and open and full of cum that the slide was obscenely easy—gooey, sticky, filthy. Fresh slick mixed with the heavy load he’d already pumped into her, creating a constant hot, wet seal around his cock. Occasional gusts of wind snuck under the draped edges of the jacket and kissed the places where she was stretched around him, cooling the mess that kept trying to leak out around his shaft with every movement of the bike.

Jungkook was a complete fucking freak for this and he reveled in it. The risk sat in his blood like the best drug he’d ever tasted—the knowledge that any car that pulled up beside them at a red light, any pedestrian who glanced too long from the sidewalk, any traffic camera that caught the wrong angle might notice the way she was pressed so tightly against him, the way her thighs trembled around his waist, the faint wet shine at the edge of the jacket if the wind lifted it just right. He kept one hand on the handlebar and the other low on her hip under the jacket, fingers digging possessively into the cum-smeared spot on her lower back, reclaiming it over and over while the city lights smeared past them in neon streaks.

“Feel that?” he called over the wind and the engine’s roar, voice cocky and rough and muffled through the helmet. “My cock still buried to the balls in your cunt while we roll past normal people living their normal little lives. You’re sitting on my dick in the middle of the city, leaking my cum down onto the seat, and no one knows. Or maybe they will. Maybe someone will look close enough and realize what a filthy secret you’re hiding under this jacket—how your used hole is stretched wide around me, how you’re cockwarming my load like a good little public cumdump.”

She made a muffled, desperate sound against his chest. Her cunt kept clenching in helpless little spasms around him every time he took a corner or hit a rough patch of asphalt, the vibrations of the engine traveling straight up into her stuffed fuckhole. He didn’t thrust. He didn’t need to. The motion of the bike did all the work—small, constant, degrading movements that kept her hyper-aware of every thick, veined inch stretching her open and every drop of cum still trapped inside her.

By the time he finally pulled into the quiet, shadowed street near her place and killed the engine in the deeper dark between streetlights, her thighs were shaking violently and her cunt was a hot, dripping, oversensitive mess around him. He planted his boots on the asphalt, steadied the bike, and reached down between their bodies.

When he started to pull out, the tight seal of her cunt broke with a filthy, wet schlick. A thick, heavy, obscene gush of mixed cum and slick immediately poured out of her—too much for her stretched, used hole to hold. It coated his cock in glossy white strands, dripped down onto the seat in sticky ropes, ran along her inner thighs in messy rivulets. Jungkook cursed under his breath, eyes locked on the overflowing wreck of her cunt, then leaned down without a second of hesitation. He licked through the gushing mess in broad, filthy strokes of his tongue, gathering the gooey mix of his cum and her cream, and pushed it back inside her open fuckhole with his mouth and fingers, forcing the overflowing load deeper again like he couldn’t stand to see any of it escape.

“You leak so much cum that even your own pussy can’t store it inside, huh?” he muttered against her soaked, twitching flesh, voice thick with dark, carnal satisfaction. “Look at this. Overflowing the second I leave your hole empty. My cum and your cream just pouring out like your cunt doesn’t know how to keep what I give it. Greedy little fuckhole needs me to push it all back in and make it stay.”

He lapped at her one more time, tongue pushing another thick pulse of the messy white load back inside, then finally pulled away, lips shiny, eyes gleaming with pure possessive filth as he looked up at her through the open visor.

The night air was cool on the wet, cum-smeared wreck between her legs.

His load was still inside her—forced back in where it belonged.

And Jungkook looked like a man who had only just started figuring out how many ways he could keep claiming her.

The night air was cool against the mess still drying on her thighs. Jungkook sat astride the bike, engine off, watching her with that same dark, unreadable expression he’d worn all night.

YN’s voice came out quieter than she expected.

“Why not just… claim me as yours forever?”

The words hung between them.

Jungkook’s gaze flicked away first. Toward the empty street. Toward the distant glow of campus lights. Anywhere but her face. The shift was subtle but immediate—like the filthy, unhinged version of him that had fucked her over the bike and made her cockwarm him through the city was folding itself back under the surface. The professor returning. The man who had something to lose.

He opened his mouth.

She saw it.

And she cut him off before a single word could leave.

"Never mind," she whispered, stepping back from the bike. She wrapped her arms around herself, instantly pulling her walls back up, hiding the raw, bleeding rejection on her face. "It's fine. Forget I said anything."

She turned on her heel and walked quickly up the pathway to her door.

Jungkook swore viciously under his breath. He kicked the stand down, killed the engine, and swung off the bike. By the time YN got her key in the lock and pushed the front door open, his heavy boots were already pounding up the porch steps.

She tried to shut the door, but his hand shot out, catching the wood and pushing it open. He followed her inside, kicking the door shut behind him with a heavy thud that echoed through the quiet living room.

"Don't just walk away like that," Jungkook warned, his voice hard, though there was a frantic edge to it now.

YN threw her keys onto the coffee table, finally spinning around to face him. The dam broke.

"Why not?!" she shouted, her voice cracking as the frustration poured out of her. "That's what you do, isn't it? You walk away! Every single day on campus, you look right through me. You act like I’m a ghost, but then you drag me into an alley the second another guy looks at me! I'm so sick of it, Jungkook! I'm sick of the shadows. I'm sick of being a dirty secret because you're too terrified to just stand next to me in the light!"

"You think this is about me being terrified?!" Jungkook shouted back, stepping right into her space, his chest heaving. "You think I want to hide you? I want to drag you in front of the entire faculty and tell them exactly whose you are! I want to break the jaw of every single kid who even breathes in your direction!"

"Then do it!" she challenged, tears of absolute frustration stinging her eyes.

"I can't!" he roared, dragging his hands through his hair, the composed, untouchable professor completely unraveling in the middle of her living room. "You’re twenty-two! You are busting your ass day and night studying for exams. Do you have any earthly idea what a university ethics scandal would do to your background check? What it would do to your entire future?"

YN blinked, the fight stuttering in her chest as his words echoed in the small room.

Jungkook dropped his hands, his dark eyes blazing, desperate and completely entirely bare. "I am not going to let an ethics committee drag your name through the mud. I'm not going to let them strip you of your degree, and I sure as hell am not going to ruin your shot at your career just because I couldn't keep my hands to myself."

He stepped closer, closing the distance until he was towering over her, his voice dropping into a ragged, desperate confession. "I don't just want to claim you, YN. I want you forever. All for myself. I want to build a life with you. Hell, I love you."

The silence that followed was absolute.

YN stared up at him, her lips parted, the air completely knocked out of her lungs. "You... what?"

Jungkook let out a shaky breath, all the fight draining out of him. He reached out, his large hands cupping her face, his thumbs gently wiping away a stray tear that had spilled over her lashes. "I love you," he repeated, the words solid, grounding, and absolutely undeniable. "I'm not hiding you because I'm ashamed. I'm hiding you because I am protecting you."

"Jungkook..." she breathed, the shock giving way to a sudden, overwhelming warmth that flooded her chest.

"Just wait," he whispered, pressing his forehead against hers. "Just wait until you graduate. The second they hand you that diploma, the second you are out of my classroom... we make it public. No more dumpsters. No more alleys. I will claim you in front of the entire damn world."

YN let out a watery laugh, her hands coming up to grip the lapels of his leather jacket. The crushing, toxic weight that had been suffocating them for months finally broke, leaving behind nothing but the sweet, bruised reality of what they actually meant to each other.

"Okay," she whispered.

Jungkook let out a long sigh of relief. He didn't waste another second. He pulled her flush against his chest and walked her backward until the backs of her knees hit the couch. They tumbled down onto the cushions together, but this time, there was no violence. There was no biting, no bruising, no desperate attempts to leave a mark.

When his mouth finally found hers, it was slow. It was deep, sweet, and incredibly soft. He kissed her like she was the most precious thing in his world, his hands tangled gently in her wavy hair, finally laying claim to her in the only way that truly mattered.

THE END.
