I've been Kazuha's personal trainer for months now, watching her sweat through sessions at this quiet local gym. She's 22, a member of LE SSERAFIM, with that tight body honed from idol life—perky tits straining against her blue sports bra, ass hugged by those blue tight sports leggings that leave nothing to the imagination. Today, the gym's mostly empty, just a few late-night stragglers on the far side, but I don't care. I've planned this. My cock's been hard thinking about breaking her, owning her famous little frame.
We start with stretches. I stand behind her as she bends over, her leggings stretching thin over her pussy mound. 'Deeper, Kazuha,' I growl, pressing my hips against her ass, feeling the heat through the fabric. She tenses but doesn't pull away—professional, always so obedient. I grab her waist, pulling her back harder, my fingers digging into her sides. 'You need to feel the burn,' I say, but my voice is thick with lust. She glances back, confused, but I smile and release her. Not yet.
Next, weights. I spot her on squats, hands on her hips guiding her down. Each time she rises, I let my thumbs brush the underside of her sports bra, feeling the soft swell of her tits. Her breathing quickens, not from exertion. 'You're doing great,' I murmur, leaning in close, my breath on her neck. She nods, focused, but I see the flush on her cheeks. After a set, I hand her water, watching her throat work as she swallows. My mind races—soon, that'll be my cock down there.
The gym quiets more; the last guy leaves, door clicking shut. It's just us now, but I want the risk. I lead her to the mats for core work. 'On your back,' I command. She lies down, legs up in bicycle crunches. I kneel between her thighs, hands on her ankles, pushing them higher. Her leggings ride up, camel toe forming perfectly. I slide my hands down her calves, then grip her thighs, spreading them wider than needed. 'Hold the position,' I say, my fingers inching toward her crotch. She squirms. 'Trainer, that's—' I cut her off, pressing my palm flat against her pussy through the fabric. 'Quiet. This is part of the workout.'
She gasps, trying to close her legs, but I force them apart, rubbing roughly over her slit. 'What are you doing? Stop!' she yelps, voice echoing in the empty space. I laugh low, groping harder, fingers outlining her folds. Her sports bra heaves with panicked breaths. I yank the bra up, exposing her nipples—pink and hardening in the cool air. I pinch one roughly, twisting until she cries out. 'These tits are mine now, idol slut.' She screams, 'No! Help!' but the gym's too deserted. I slap her face lightly. 'Scream louder; maybe someone hears your K-pop ass getting owned.'
I flip her onto her stomach for planks, but instead, I straddle her back, grinding my hard cock against her ass. She bucks, sobbing, but I pin her arms. Ripping at her leggings, I tear a hole right over her asshole and pussy—fabric shredding loud in the silence. Her bare ass cheeks spill out, pale and perfect. 'Look at that,' I degrade her, spanking hard, leaving red prints. 'Famous girl, exposed like a whore in public.' The gym mirrors reflect us; anyone walking in sees her holes winking through the rip.
I shove two fingers into her dry pussy, fingering roughly, stretching her walls. She screams, body jerking. 'Tight little cunt,' I grunt, adding a third finger, pumping fast. Her juices start unwillingly, betraying her. I pull out, slick fingers to her mouth. 'Suck them clean.' She clamps her lips, so I force them in, mouth-fingering her, gagging her on her own taste. She chokes, tears streaming, as I fuck her mouth with my digits.
Standing now, I drag her up by her hair, slamming her against the weight rack—public view from the windows. I unzip, cock springing free, thick and veined. 'On your knees, bitch.' She shakes her head, screaming, but I force her down, shoving my cock into her mouth. Deepthroat—balls slapping her chin as I plow her throat. She gags violently, vomit bubbling at the corners, but I hold her head, fucking relentlessly. 'Choke on it, LE SSERAFIM whore. Your fans would love this.' Drool cascades down her chin onto her exposed tits.
I pull out, strings of spit connecting us, and bend her over the bench press—prone-bone style. Her ripped leggings frame her holes. I spit on her asshole, then ram my cock in dry. She howls, 'It hurts! Stop!' Anal rape, tight ring tearing around me. I plow deep, balls slapping her pussy, dominating every inch. Her screams turn to whimpers as I ream her ass, pulling out to slap it red.
Not done. I flip her onto her back for mating press—legs folded to her chest, holes splayed. Vaginal now: I slam into her pussy, fingering her clit roughly while thrusting. She claws at me, but I pin her wrists. 'Take it, you degraded slut. Your body's for fucking.' I lean down, biting her nipples, twisting them hard—nipple play making her arch in pain.
I grab my gym bag, pulling out toys. First, anal beads—thick string of them, I shove into her ass while still buried in her pussy. She screams as I yank them out, one by one, her hole gaping. Then a vibrator—buzzing against her clit while I fuck her harder. Her body betrays her again, clenching around me.
Standing sex next: I hoist her up, her legs wrapping unwillingly around me as I carry-fuck her across the gym floor. Carry sex, bouncing her on my cock—vaginal deep, her tits jiggling. Windows overlook the street; cars pass, potential eyes on us. 'Public fuck for the idol,' I humiliate, slapping her ass. She sobs, 'Please, no... people will see.' I laugh, 'That's the point, cumdump.'
Full-nelson now: I lock her arms behind her head, lifting her like a ragdoll, impaling her ass on my cock again. Facing the mirrors, she sees herself—debased, holes used. I bounce her, degrading: 'Look at your ruined makeup, whore. LE SSERAFIM's ass-toy.' Her screams mix with gags as I choke her with my belt from the bag—strangulation, leather tight around her throat. Her face purples, eyes bulging, but I don't let up, plowing her asshole while she gasps.
Filming it all—phone propped on a dumbbell, capturing every thrust, every scream. 'Smile for your fans,' I taunt, zooming on her creampied ass as I finally unload—hot cum flooding her bowels, leaking out through the ripped leggings.
I drop her to the mat, spent, her body twitching, holes wrecked. 'Good session, Kazuha. Same time next week.' She curls up, humiliated, broken—but my cock twitches already for more.
I watch Kazuha curl up on the gym mat, her body a mess—cum dripping from her torn asshole through the shredded leggings, tits still out, face streaked with tears and spit. She's whimpering, broken, but that just makes my cock stir again. I can't stop here; the night's young, and I want the world to see what a filthy idol slut she is. Grabbing her by the hair, I yank her to her feet. 'We're not done, whore. Time for a real workout—outside.' She stumbles, legs shaking, begging, 'No, please... let me go.' I slap her ass hard, the rip in her pants exposing her cheeks. 'Shut up and walk, or I'll drag you naked.'
I shove her toward the exit, one hand clamped on her arm, the other groping her tit roughly through the bunched-up bra. The cool night air hits us as we step out—streetlights buzzing, distant traffic. The local park's just a block away, always busy with late joggers, dog walkers, and couples. Perfect for breaking her publicly. I march her there, her exposed holes flashing with every step. People glance— a guy on his phone does a double-take, smirking. Kazuha tries to cover herself, but I twist her arm behind her back. 'Hands down, bitch. Let them see LE SSERAFIM's used cunt.'
We reach the park entrance, paths lit by lamps, benches scattered. A group of young guys playing basketball nearby, a woman walking her dog, families lingering from evening picnics. I spot a secluded-ish clearing by the trees, but still visible—enough cover to start, but open for an audience. I push her into the grass, face down. She screams, 'Help! Someone!' Heads turn; the basketball guys pause, murmuring. One pulls out his phone. Good—let them film.
Prone-bone again: I drop my pants, kneel over her, and slam my cock back into her ass. No lube, just the remnants of my earlier load. She howls, body bucking wildly under me. 'Fuck, your shithole's looser now, slut. But still tight enough to ruin.' I plow deep, hips crashing against her cheeks, the rip in her leggings framing the brutal invasion. Her screams echo—raw, desperate. The dog walker freezes, then hurries off, but the basketball crew edges closer, phones out, capturing every thrust. 'Yo, is that... Kazuha? Holy shit, she's getting reamed!' one laughs. Humiliation burns her face red as she realizes. I degrade her louder: 'Hear that, idol? Your fans are watching you get ass-fucked like a street whore.'
I grab the belt from my waist—forgot the gym one, but this works. Loop it around her neck, pulling tight like reins. Strangulation kicks in; she gags, choking as I yank back, arching her body. Her ass clenches around my cock from the lack of air, milking me harder. 'Choke on it, you worthless cumrag. Scream for your audience.' She rasps, eyes watering, but I don't ease up, plowing faster, dominating her completely. The guys cheer now, zooming in—'Deeper, man! Wreck that K-pop ass!'
Pulling out, I flip her over for mating press in the open grass. Legs pinned to her shoulders, her pussy and ass on full display through the hole. A small crowd forms—more phones lighting up, people whispering, 'That's really her... filming this shit.' I ram into her pussy this time, vaginal rape brutal and unrelenting. Fingers dig into her clit, fingering roughly, pinching until she shrieks. 'Your famous twat's dripping for strangers now, huh? Bet your groupmates would disown a park slut like you.' She claws the dirt, sobbing, but her hips twitch involuntarily. I lean in, mauling her nipples—twisting, pulling, biting until they're swollen and bruised. Nipple play makes her arch, pain mixing with the forced pleasure.
From my pocket, I pull the vibrator—still buzzing from the gym bag I grabbed on the way out. Shove it against her clit while thrusting, the hum mixing with her gurgled screams. Her body convulses, pussy squirting around my cock despite the tears. 'Look at you, cumming in public like a depraved bitch.' The crowd grows— a couple joins, the woman shocked but filming too. 'Oh my god, he's destroying her...'
Anal beads next: I yank the vibe out, stuff the beads into her ass one by one—thick, unyielding. She wails as they stretch her, then I tug them free in a rush, her hole gaping wide for all to see. 'Smile for the cameras, whore. This vid's going viral.' Phones flash; I hear clicks and laughs. Humiliation peaks—she covers her face, but I slap her hands away. 'Eyes open. Let them see LE SSERAFIM's ruined holes.'
Standing now, I hoist her up—carry sex, her legs dangling as I impale her pussy on my cock. Bouncing her like a fucktoy, I walk her deeper into the park, toward the lit path. People scatter and gather; a jogger stops dead, phone out. 'Public fuck for the star,' I grunt, slamming up into her with each step. Her tits bounce wildly, bra long discarded in the grass. She screams, 'Stop! Everyone's watching!' I laugh, groping her ass, fingers probing the ripped fabric. 'That's right—your degradation's entertainment now.'
Full-nelson variation: I shift, locking her arms behind her head, facing the crowd. Ass impaled again, I lift and drop her on my cock, her body on display. Strangers circle closer, filming from all angles—deepthroat prep. I lower her to her knees mid-thrust, forcing her mouth onto me. Oral rape: cock straight from her ass to her throat. She gags hard, retching as I deepthroat her, balls smacking her chin. 'Taste your shithole, idol. Clean it for your fans.' Vomit dribbles, but I hold her nose, making her choke deeper. The crowd whoops—'Suck it, bitch!' one yells.
Mouth-fingering follows: I pull out, shove three fingers down her throat, gagging her until she pukes a little, then smear it over her face. 'Filthy pig. LE SSERAFIM's vomit-slut.' She heaves, humiliated, as flashes continue. Back to standing sex: I pin her against a tree, one leg hooked over my arm, plowing her pussy while the crowd films. Rough groping everywhere—tits squeezed, ass spanked raw. 'Beg for more, you degraded toy.' She doesn't, just screams, but I choke her with my hand now, belt dangling.
Finally, I drag her to a bench—prone over it, ass up for all. Anal creampie incoming: I ream her shithole one last time, brutal and fast, the crowd chanting 'Cum in her! Cum in her!' Phones capture the load as I explode, hot spurts filling her bowels, overflowing down her thighs. I pull out, letting it leak publicly, then finger her ass to push more in, degrading: 'Keep it plugged, whore. Walk home like that.'
The crowd disperses slowly, vids already uploading. Kazuha collapses on the bench, wrecked, sobbing. I zip up, pat her head. 'Best session yet. Fans'll love the show.' She doesn't respond—just broken, exposed under the stars.
Kazuha lies sprawled on the park bench, her body limp and glistening with sweat, cum, and dirt from the grass. Her leggings are in tatters around her thighs, pussy and ass leaking my load onto the wood. She's sobbing quietly, eyes half-lidded, but the fire in me isn't out—it's raging. The crowd's thinning, but those basketball guys linger, eyes hungry, phones still recording. I spot them: four dudes, early twenties, built like athletes, smirks on their faces. 'Hey, fellas,' I call out, voice casual like we're buddies. 'This idol slut's up for sharing. Who's first?' They exchange glances, then grin, circling closer. Kazuha whimpers, trying to curl up, but I grab her ankles and drag her off the bench onto the path—right under the streetlamp for maximum exposure. Joggers slow down, a family nearby gasps and pulls out their phone instead of calling help. Public spectacle's just starting.
One guy—tall, buzzcut—steps up first. 'For real? LE SSERAFIM's Kazuha? Fuck yeah.' I nod, yanking her arms behind her back. From my gym bag (I fetched it quick), I pull handcuffs—standard trainer gear for 'motivation.' Click them on her wrists, cold metal biting her skin. She thrashes weakly. 'No, please... don't let them...' I slap her face hard, stunning her. 'Shut it, toy. You're public property now.' Buzzcut drops his shorts, his thick cock springing free—veiny, already hard. He grabs her hair, forces her mouth open, and shoves in deep. Oral assault: he face-fucks her roughly, hips pistoning, balls slapping her chin. She gags, drool spilling, but he doesn't stop, choking her throat with each thrust.
Meanwhile, I kneel behind her, spreading her legs wide in a forced split on the concrete path. Her pussy's swollen, red from earlier abuse. I ram my cock back into her ass—no prep, just brutal entry. Anal rape resumes, my hips slamming against her cheeks, the handcuffs rattling with every pound. She's muffled around Buzzcut's dick, body rocking between us. The other guys cheer, one filming close-up of her stretched holes. 'Look at that gape—dude wrecked her good.' A small crowd gathers: late-night walkers, a couple on a date, even an older man with a camera. Whispers turn to excited murmurs; no one's intervening—this is viral gold.
Buzzcut pulls out, strings of spit connecting his cock to her lips. 'My turn on that ass.' I slide free, letting him take over. He flips her onto her back—missionary style, but rough. Legs hooked over his shoulders, he plunges into her pussy, folding her in half. Vaginal pounding: deep, savage strokes that make her tits jiggle. She screams, but I straddle her chest, pinching her nipples viciously—twisting until they're purple, then slapping them red. 'Scream louder, whore. Entertain your audience.' Her cries draw more eyes; phones light up the night, capturing the gangbang.
Next guy—stocky, tattooed—joins in. He uncuffs one hand quick, only to tie her wrists to her ankles with my belt, hogtying her on the path. Body arched, ass and pussy up like an offering. 'Hogtied idol—perfect.' He mounts her from behind, doggy-style variation: cock spearing her ass while she's bound. The position stretches her painfully, holes exposed to the crowd. He spanks her cheeks raw, leaving handprints, then chokes her with his forearm—strangulation tight, her face turning blue. She gasps, vision blurring, but he keeps thrusting, ass-fucking her unconscious. Her body goes slack mid-thrust, eyes rolling back—out cold from the pressure on her throat. Unconscious rape: he doesn't stop, plowing her limp form, the crowd gasping. 'She's passed out—keep going!' one films.
I take her mouth while she's out, deepthroating her flaccid throat. No resistance; her head lolls as I fuck her face, cock bulging her neck. Cum from earlier mixes with fresh drool, bubbling out. The fourth guy—lean, pierced—waits his turn, stroking himself. When Stocky finishes, dumping a load in her ass (hot spurts overflowing), he cuts in. Unties her partially, just enough to flip her into reverse cowgirl on the path. But she's still dazed, barely conscious. He sits, impales her pussy on his cock, and bounces her like a ragdoll—her bound hands flailing. Public eyes everywhere: a woman nearby bites her lip, filming discreetly; teens on bikes stop to watch.
Strangulation round two: I loop the belt around her neck again, pulling from behind while Pierced thrusts up. She chokes awake, coughing, but the air denial makes her pussy clench. 'Fight it, slut—makes you tighter.' He gropes her clit, rubbing hard, forcing twitches from her body. The guys rotate: Buzzcut takes her ass now, double penetration—his cock in her shithole while Pierced stays in her pussy. DP gangrape: both pounding in sync, her body sandwiched, holes stretched to tearing. She wails hoarsely, the belt yanking her head back. Crowd's bigger—twenty people now, a mix of shocked and aroused, all recording. 'Gangbanged in the park—Kazuha's done for.' Flashes pop; I hear laughs and moans from onlookers.
They hogtie her fully again—wrists to ankles, belt cinched tight—rolling her onto her side for side-fuck. Lean guy slides into her mouth, skull-fucking the bound idol. Unconscious edges in: she fades from the strain, body limp as he throat-pies her, cum shooting straight down. I reclaim her pussy, missionary with legs pinned, choking her awake with my hands—thumbs on her windpipe, squeezing until she bucks. Brutal vaginal rape: I drill deep, balls-deep every time, her walls raw and unwilling. Tattoos grabs her tits, mauling them—sucking nipples hard, biting until blood beads.
Full gang shift: All four plus me now, rotating positions. One in her ass (prone bone on the grass), one in her pussy (spooning beside), one in her mouth (kneeling), and the last jerking over her face. Handcuffs back on, belt for hogtie accents. She's a bound, multi-holed fuckmeat—screams turning to gurgles. Strangulation cycles: each guy chokes her during their turn, her passing out repeatedly, only to be revived by slaps or thrusts. Public humiliation peaks—a news van pulls up nearby (someone called it in?), but the crew films too, lights on the scene. 'Live gangrape—idol exposed!'
Positions vary wildly: Wheelbarrow—holding her hips up, legs spread, two guys alternating her holes while bound. Standing carry—Pierced lifts her hogtied form, impaling her ass, walking her around the crowd like a trophy, strangers groping her swinging tits. Lotus wrap: Buzzcut sits cross-legged, her on his lap reverse, cock in pussy, me behind for anal DP, belt choking her from the front. She squirts unwillingly during a forced orgasm, soaking the path, crowd cheering.
Final brutality: We untie her, cuff her spread-eagle to the bench—arms and legs wide. Gang creampie train: Each unloads—pussy first (Stocky floods her womb), then ass (Buzzcut fills her bowels), mouth (Pierced throat-cums), and I take the face, painting her features white. Unconscious again from exhaustion, she doesn't stir as we finger the loads deeper, plugging her with park trash—a bottle neck in her pussy, stick in her ass. 'Stay full, whore.' The crowd applauds, vids spreading online already.
We leave her there—cuffed, leaking, broken under the lamps. 'Session two tomorrow,' I tell the guys. They nod, pumped for more. Kazuha twitches faintly, the night air cooling her ruined body. Public legend born.
