Backstage Backflow

The roar of the crowd at Waterbomb still echoed in your ears as you and your friend wrapped up the event. As the MC, you'd hyped up the audience all day, and as the photographer, he'd captured every splash and strut. Lightsum's performance had been electric—Nayoung and Juhyeon especially, strutting in those barely-there outfits that left little to the imagination. Tiny bikinis clung to their sweat-slicked bodies, the fabric so sheer it might as well have been painted on. Nayoung's curves strained against the top, her big tits bouncing with every hip thrust, while Juhyeon's ass cheeks peeked out from her bottoms, teasing the front row with every grind.

Backstage, the air was thick with post-show adrenaline. The other four members of Lightsum—Yujeong, Sangah, Hina, and Chowon—were already buzzing about heading out. 'Our guys are waiting,' Chowon giggled, towel-drying her hair. They grabbed their bags and dashed off, leaving just Nayoung and Juhyeon lingering by the dressing room mirrors, still flushed and glowing under the harsh lights. You and your friend hung back, packing up gear, stealing glances at the two singles. As die-hard fans, you'd always crushed on them—Nayoung's playful smirk and Juhyeon's sultry gaze had fueled more than a few late-night fantasies.

Nayoung caught your eye first, her lips curving into a wicked smile as she adjusted her top, the fabric slipping just enough to flash a hint of nipple. 'Hey, MC and camera guy,' she called, her voice husky from singing. 'You two were great out there. Kept the energy up.' Juhyeon sidled up beside her, fanning herself with a hand, her shorts riding high on her thighs. 'Yeah, super hot day. We're still wired. The others are bailing to see their boyfriends, but we're free. Want to... hang out? Backstage fun?'

Your friend shot you a look, his eyebrows shooting up. You nodded subtly, heart pounding. One conversation led to another—talking about the set, the crowd's screams, how their bodies felt alive on stage. The door clicked shut behind the last staff member, leaving the four of you alone in the dimming lights of the backstage area. The fluorescent bulbs overhead flickered slightly as the energy of the event began to wind down, casting long shadows across the cluttered dressing room. Mirrors lined one wall, still smeared with remnants of makeup and sweat from the performance, and scattered towels and water bottles littered the floor. The air hung heavy with the scent of chlorine from the Waterbomb pools outside, mixed with the faint, musky aroma of exertion that clung to everyone's skin.

Nayoung laughed at something your friend said, then boldly swung a leg over his lap, settling down with a grind that made him groan. 'Oops,' she teased. Soon, her body relaxed, the thin fabric of her bikini bottoms pressing against the growing hardness she could feel beneath her. She shifted deliberately, a subtle roll of her hips that drew a low hiss from him. His hands, which had been tentatively resting on her waist, now slid upward, fingers brushing the undersides of her full breasts. She didn't pull away; instead, she leaned in closer, her breath warm against his ear. 'You know, being on stage like that... all those eyes on us... it gets a girl thinking,' she murmured, her voice low and teasing, laced with the remnants of her stage persona.

our friend swallowed hard, his palms finally cupping the weight of her tits fully now, thumbs grazing over the hardened peaks of her nipples through the damp material. Nayoung arched her back slightly, pushing into his touch, her lips curving into a sly smile as she ground down again, slower this time, feeling his cock twitch in response. 'Mmm, you like that? The way I move?' She circled her hips in a lazy figure-eight, the friction building heat between them, her ass cheeks flexing against his thighs.

Across from them, Juhyeon had closed the distance to you, her body language shifting from casual to inviting. She stood close enough that you could feel the warmth radiating from her skin, her eyes locked on yours with an intensity that made your pulse quicken. 'You were staring during the set,' she said softly, her fingers trailing lightly up your arm, nails scraping just enough to send a shiver down your spine. 'I saw you. Made me wonder what you'd do if we weren't on stage.' Her hand continued its path, resting on your chest before sliding lower, palm flat against your abdomen, stopping just short of your waistband.

You reached out, your hand finding her hip, pulling her nearer until her thigh brushed against yours. She stepped between your legs as you sat on the edge of a makeup stool, her body swaying gently as if still to the beat of their performance music. Juhyeon leaned down, her lips hovering inches from yours, teasing without committing. 'Kiss me,' she whispered, but when you leaned in, she pulled back just a fraction, giggling softly. 'Not yet. Make me want it.' Her hand dipped lower, fingers dancing over the front of your pants, tracing the outline of your hardening cock without pressing down.

Meanwhile, Nayoung's grinding grew more insistent, her breaths coming in soft pants as she rocked against your friend's lap. He groaned, his grip tightening on her breasts, squeezing the soft flesh until she whimpered. 'God, these are perfect,' he muttered, his voice rough. She laughed, a throaty sound, and tugged at the strings of her bikini top, letting it loosen but not fall. 'You want to see them? Earn it.' She bounced lightly once, then twice, the motion jolting his erection against her core, her pussy lips parting slightly under the fabric as she felt the dampness building.

The room felt smaller now, the outside world fading as the teasing escalated. Juhyeon finally closed the gap, her lips brushing yours in a feather-light kiss before deepening it, her tongue flicking out to taste you. As she kissed you, her hand finally cupped your cock through your pants, rubbing in slow, deliberate strokes that made your hips buck involuntarily. She broke the kiss to nip at your jawline, her free hand tangling in your shirt collar. 'You're so hard already. Bet you've been thinking about this.' She ground her thigh against your bulge, mimicking Nayoung's movements, her body heat seeping through the layers of clothing.

Your friend, emboldened, yanked Nayoung's top free, her heavy tits spilling out, nipples erect and begging for attention. He latched onto one with his mouth, sucking hard while his hand kneaded the other, pinching the sensitive bud between his fingers. Nayoung moaned loudly, her head falling back as she increased the pressure of her grinding, her shorts soaking through from her arousal. 'Fuck, yes... keep doing that.' She reached behind her, fumbling with his zipper, but paused to tease, palming his cock over the fabric instead. 'Not yet. I want to feel you throb first.'

Juhyeon mirrored the action, straddling your lap now, her ass settling firmly against your erection as she rocked forward and back. The seam of her shorts rubbed against you, creating delicious friction that had you gripping her waist to hold her in place. She kissed you again, deeper this time, her tongue exploring your mouth while her hips undulated, grinding her pussy along your length. 'You like how wet I am? All from dancing for you out there.' Her words were punctuated by the soft sounds of fabric shifting, her breaths hot against your neck as she nuzzled there.

Time stretched, the build-up deliberate and torturous. Nayoung dismounted briefly, only to turn around and grind reverse on your friend's lap, her ass cheeks spreading over his thighs as she pressed back. He reached around, fingers slipping under her bottoms to stroke her slick folds, dipping just inside before pulling away. 'Tease,' she complained, but her voice was breathy, needy. She grabbed his hands, guiding them back to her tits, making him squeeze while she bounced, the motion making her breasts jiggle in his palms.

Juhyeon followed suit, spinning to face away from you, her firm ass grinding down hard. You could feel the heat of her through your pants, her movements syncing with Nayoung's, as if the two idols were performing an encore just for you two. Your hands roamed her body, one sliding up to cup a breast, the other dipping between her legs to rub her clit over the fabric. She gasped, pushing back harder, her grinding turning frantic. 'Touch me more... right there.'

The teasing continued for what felt like hours, though it was mere minutes stretched by anticipation. Clothes began to loosen—shirts unbuttoned, pants unzipped—but no one rushed to remove them fully. Nayoung leaned back against your friend's chest, her hand reaching into his open fly to stroke his bare cock, slow and firm, while she ground her ass against his base. 'Feel how big you are? I want it, but not yet.' He thrust up into her hand, his mouth on her neck, biting lightly.

Juhyeon turned to face you again, her shorts pushed aside just enough for your fingers to slip inside, feeling her soaked pussy clench around them. She rode your hand while grinding on your cock, her lips finding yours in sloppy, heated kisses. 'You're driving me crazy,' she panted, her body trembling with restrained need.

Finally, the tension snapped toward action. Nayoung slid off your friend's lap, kneeling between his legs with a predatory grin. 'Time to show you what my mouth can do.' She freed his cock fully, thick and veined, pulsing in the cool air. Juhyeon followed, dropping to her knees in front of you, her eyes gleaming with challenge as she unzipped you. 'Let's see who can cum first.'

Nayoung started slow, her tongue flicking out to lap at the precum beading on your friend's tip. She circled the head deliberately, savoring the taste, before parting her lips to suck just the crown inside. Her hand wrapped around the base, pumping in time with her mouth, while her free hand cupped his balls, rolling them gently. He groaned, fingers threading into her hair, not pulling yet but holding, guiding her rhythm.

Juhyeon mirrored her, licking a long stripe up your shaft before taking you into her warm mouth. She bobbed shallowly at first, her tongue pressing against the underside, swirling around the sensitive spot just below the head. Her hand twisted as she stroked what her lips couldn't reach, her eyes locked on yours, dark with lust.

The competition ignited slowly, building like their performance. Nayoung took more of your friend in, inch by inch, her cheeks hollowing as she sucked harder. Saliva dripped down his length, making her hand glide smoothly. 'Watch me,' she mumbled around him, glancing at Juhyeon. Juhyeon responded by relaxing her throat, sliding down further, gagging softly but pushing on until half your cock was buried in her mouth.

Your friend tightened his grip on Nayoung's hair, pulling her head back slightly to watch her lips stretch around him before guiding her down again. 'Deeper,' he urged, and she complied, throat opening to take him fully, nose pressing against his abdomen. She held there, swallowing around him, the constriction making him buck.

Juhyeon pulled off you with a gasp, strings of spit connecting her to your cock. 'Not bad, unnie. But I can do better.' She dove back down, forcing herself to deepthroat you in one go, her throat convulsing as she suppressed her gag. You felt the tight ring of her esophagus squeeze your head, and you grabbed her hair roughly, holding her in place while she hummed, the vibration traveling straight to your balls.

Nayoung popped off your friend, wiping her mouth with the back of her hand. 'Oh, it's on.' She attacked again, bobbing rapidly, her head a blur as she deepthroated him repeatedly, gagging loudly each time but refusing to stop. Saliva poured from her lips, soaking his balls, and he yanked her hair harder, fucking her face with shallow thrusts. Her tits bounced with the motion, nipples grazing his thighs.

The girls raced, switching techniques to outdo each other. Juhyeon used her tongue to lap at your slit while deepthroating, her hand squeezing your base. You pulled her hair, controlling the pace, slamming her down until tears welled in her eyes. 'Good girl, take it all,' you growled, and she moaned in response, the sound muffled.

Nayoung, not to be outdone, pulled back from your friend's cock, her lips swollen and shiny. 'Let me show you something else.' She pressed her big tits together around his slick shaft, enveloping him in soft, warm flesh. She began to slide up and down, her nipples hardening further from the friction, the head of his cock peeking out with each stroke. 'Like my tits? Fuck them.' He thrust into the valley, groaning as she licked the tip whenever it emerged, her tongue flicking rapidly.

Juhyeon watched, then redoubled on you, deepthroating with renewed vigor, her throat bulging as she took you to the hilt. Her hand reached over to tweak Nayoung's nipple, urging her on. 'Don't stop, but I bet I make him cum first.' Nayoung laughed, squeezing her breasts tighter around your friend, pumping faster, her saliva providing perfect lubrication.

The titjob intensified, Nayoung's movements fluid and teasing, alternating between slow glides and quick bounces. Your friend's hands fisted in her hair again, pulling her head down so she could suck the tip while tit-fucking him. 'Shit, Nayoung... so good.' She hummed approval, the vibration adding to the sensation.

Juhyeon gagged on your cock, her pace frantic now, saliva dripping onto your balls as she deepthroated relentlessly. You held her hair tight, face-fucking her, the wet slurps filling the room. The mirrors reflected the scene—two idols on their knees, one buried between massive tits, the other choking on cock.

Tension built to a peak. Your friend came first, pulling out of Nayoung's tits to stroke himself, ropes of cum splattering across her heaving breasts. She arched back, letting it coat her skin, rubbing it in with her fingers, nipples glistening white.

You followed seconds later, gripping Juhyeon's hair and thrusting deep as you erupted down her throat. She swallowed every spurt, milking you with her mouth until you were spent, pulling off with a satisfied gasp, lips sealed tight.

The afterglow lingered only for a moment, the room thick with the scent of sex and sweat, but your friend wasn't done. His eyes darkened as he looked down at Nayoung, her chest still heaving, cum glistening on her full tits like a perverse trophy. She smirked up at him, wiping a stray drop from her nipple with her finger and sucking it clean, her tongue swirling deliberately. 'That all you got?' she taunted, her voice husky, challenging him even as her body trembled from the intensity.

He stood abruptly, his cock still semi-hard and slick from her mouth, towering over her kneeling form. 'Oh, we're just getting started, Nayoung.' Grabbing her by the waist, he hauled her up with surprising strength, spinning her around to face away from him. She gasped in surprise but complied eagerly, her hands bracing against a nearby vanity table littered with makeup brushes and empty water bottles. But he wasn't satisfied with that. 'Bend over more,' he growled, his hands pressing firmly on her lower back, forcing her spine to arch until her fingertips grazed the floor, her ass high in the air, legs spread just enough to expose her dripping pussy.

Nayoung's bikini bottoms had long since been tugged aside, the fabric bunched uselessly to one side, revealing her swollen lips glistening with arousal. She balanced precariously on her toes, her big tits hanging heavy beneath her, swaying slightly with each breath. 'Like this?' she purred, wiggling her hips teasingly, her ass cheeks parting to give him a full view of her tight holes. The position stretched her thighs, making her feel exposed and vulnerable, but the thrill sent fresh heat pooling between her legs.

Your friend dropped to his knees behind her, his hands gripping her ass firmly, spreading her cheeks wider. 'Fuck, look at that pretty pussy,' he muttered, his breath hot against her skin. He leaned in, inhaling her musky scent before dragging his tongue flat along her slit, from her clit to her entrance. Nayoung moaned immediately, a deep, throaty 'Ahh...' escaping her lips as her body jolted. His tongue delved deeper, lapping at her folds with broad strokes, tasting the tangy sweetness of her juices. He circled her clit slowly at first, flicking it lightly, then sucking it between his lips with gentle pressure.

'Mmm, yes... right there,' Nayoung whimpered, her fingers curling against the floor, knuckles whitening as she tried to stay balanced. He ate her out ravenously, his mouth working her over with sloppy, wet sounds—slurps and smacks echoing in the quiet room. His tongue thrust inside her, fucking her shallowly while his nose bumped against her clit, the dual sensation making her thighs quiver. One hand slid up her inner thigh, fingers joining his tongue to spread her open wider, dipping in to curl against her G-spot. She bucked back against his face, grinding her pussy on his mouth, her moans growing louder: 'Oh god, don't stop... eat that pussy, fuck...'

Across the room, Juhyeon watched the scene with hooded eyes, her throat still raw from swallowing your load, a dribble of cum lingering at the corner of her mouth. She licked it away, then turned her gaze to you, crawling closer on her hands and knees like a predator. 'Your turn to taste me,' she said, her voice breathy, standing and pushing you back onto the worn couch that sat against the far wall. The cushions sagged under your weight, springs creaking softly. She straddled your chest briefly, her soaked shorts inches from your face, before shimmying them off, kicking them aside to reveal her bare pussy, lips puffy and slick.

You grabbed her hips, pulling her forward until her thighs framed your head, her knees sinking into the couch on either side. 'Sit on my face,' you commanded, and she did, lowering herself slowly, teasingly, until her wet heat pressed against your mouth. Your tongue shot out immediately, licking up her seam in one long drag, savoring the salty-sweet flavor of her arousal. Juhyeon gasped, her hands bracing on the wall behind the couch for support. 'Yesss... just like that,' she hissed, rocking her hips to smear her juices across your lips and chin.

You devoured her with fervor, your mouth sealing over her clit, sucking hard while your tongue lashed at it relentlessly. Her folds parted under your assault, and you plunged your tongue deep inside, thrusting in and out, mimicking a cock. Juhyeon's moans filled the air—sharp 'Ah! Ah!' cries interspersed with deeper groans—as she ground down, fucking your face with abandon. Your hands kneaded her ass, fingers digging into the firm flesh, occasionally slipping to tease her puckered hole. She trembled above you, her pussy clenching around nothing, juices dripping down your neck.

Minutes stretched as the two of you worshipped the girls' bodies. Nayoung's cries grew more desperate, her body undulating in that bent-over pose, tits swinging like pendulums with each lap of your friend's tongue. 'Fuck, I'm so wet... your tongue feels so good inside me,' she panted, her voice breaking into a whine when he sucked her clit hard, his fingers now pumping in and out of her pussy, three thick digits stretching her. The squelching sounds of her wetness mixed with her moans, creating a symphony of lust.

Juhyeon rode your face harder, her thighs clamping around your head, muffling her sounds slightly but not enough to hide the 'Mmmph! Oh shit...' grunts she let out. Your nose pressed into her clit while your tongue fucked her hole, and she reached down to pinch her own nipples, twisting them as pleasure built. 'Deeper...fuck, your tongue is amazing' she whimpered, her hips circling in tight loops.

Your friend couldn't hold back any longer. Rising to his feet, his cock now rock-hard again, veined and throbbing, he positioned himself behind Nayoung. He rubbed the head along her slit, coating himself in her slickness, teasing her entrance. 'You ready for this cock?' he asked, voice rough. Nayoung pushed back impatiently. 'Yes, fuck me already' . With one powerful thrust, he buried himself balls-deep, her pussy walls gripping him like a vice. She cried out, a loud 'Fuuuck!' that echoed off the mirrors, her hands slipping on the floor from the force.

He didn't give her time to adjust, pulling back almost all the way before slamming in again, setting a brutal pace. His hips snapped against her ass, skin slapping loudly—'Pak! Pak! Pak!'—as he fucked her roughly, his hands gripping her hips to hold her in place. Nayoung's body rocked forward with each thrust, her tits bouncing wildly, heavy orbs swinging uncontrollably beneath her, nipples grazing the floor occasionally. 'Harder! Own this pussy!' she screamed, her voice raw, pushing back to meet him, the angle making his cock hit deep, brushing her cervix.

You pulled Juhyeon off your face, her chin slick with her own juices, and flipped her around. 'My turn to have some fun,' you said, guiding her to bend over the arm of the couch, her upper body draped across the cushions, ass up and presented. Her pussy winked at you, dripping and ready. You knelt behind her, spreading her cheeks and diving in one last time with your mouth, tongue lapping at her from behind for a few more teasing licks. She moaned into the fabric, 'Hurry... I need your cock in me now.' Satisfied, you stood, aligning your throbbing length with her entrance and thrusting in smoothly, her heat enveloping you inch by inch.

Juhyeon arched her back, a guttural 'Oh god, yes!' tearing from her throat as you bottomed out. You started slow, rolling your hips to let her adjust, but soon picked up speed, fucking her with deep, measured strokes. Your hand came down on her ass cheek with a sharp 'Crack!', the sound mingling with her yelp of pleasure. 'You like that?' you asked, slapping again, watching the skin redden under your palm. 'Yes! Slap my ass harder... fuck me like you mean it,' she begged, her pussy clenching around you in response.

The room devolved into a cacophony of sex: the wet 'Schlick! Schlick!' of cocks plunging into soaked pussies, the rhythmic 'Slap! Slap!' of hips meeting asses, and the girls' unending moans. Nayoung's were high-pitched and frantic—'Ah! Ah! Fuck, so deep... don't stop!'—while Juhyeon's were lower, more growly—'Mmm, yes... harder, slap it again!' Your friend grunted with each thrust, his balls smacking against Nayoung's clit, driving her wild. You alternated slaps on Juhyeon's ass with grips on her hips, pulling her back onto your cock, the force making the couch creak.

As the fucking intensified, Nayoung and Juhyeon twisted their heads to face each other, their eyes locking across the short distance. Sweat beaded on their foreheads, faces flushed with exertion and ecstasy. Nayoung's gaze was wild, pupils blown wide, while Juhyeon's held a mischievous spark. 'You look so hot getting fucked,' Nayoung panted between thrusts, her tits still swinging erratically, brushing against Juhyeon's arm as she reached out.

Juhyeon extended her hand too, their fingers intertwining briefly before she leaned closer, straining against your pounding. 'So do you unnie... come here.' Their lips met in a sensual kiss, slow and deep despite the rough treatment their bodies were enduring. Tongues danced lazily, contrasting the brutal rhythm of the cocks slamming into them. Juhyeon's free hand snaked forward, pinching Nayoung's swinging tit hard, twisting the nipple until Nayoung broke the kiss with a sharp 'Ow! Fuck, that hurts so good...' But she dove back in, moaning into Juhyeon's mouth, the pinch sending jolts straight to her core.

The kissing grew sloppier, wet smacks of lips joining the fucking sounds, their breaths mingling in hot pants. Juhyeon pinched again, rolling the hardened bud between her fingers, making Nayoung's pussy flutter around your friend's cock. 'Your tits are amazing... so big and bouncy,' Juhyeon murmured against her lips, eliciting a throaty laugh from Nayoung. 'Pinch 'em harder while he wrecks me.' The girls' moans vibrated into each other, a shared symphony of pleasure.

Your friend leaned over Nayoung's back, one hand reaching around to rub her clit in fast circles, the other pulling her hair to arch her neck for better leverage. 'Take it, you slutty idol... your pussy's milking me so tight.' Nayoung whimpered into the kiss, her body shaking from the overload. You mirrored him, slapping Juhyeon's ass red before sliding a hand under her to flick her clit, your thrusts turning erratic as her walls tightened.

Suddenly, Juhyeon's phone buzzed on the nearby table, the screen lighting up with 'Hina calling.' She groaned in annoyance but reached for it, swiping to answer while you kept fucking her steadily. 'H-Hey, Hina... what's up?' she managed, her voice strained, biting her lip to stifle a moan as your cock hit a particularly sensitive spot.
