A/N ⎯⎯ I thought about this smut all night while listening to Rain Paris. I don't usually write about smut, so I'm sorry if something went wrong .ᐟ ♡
‼️ㅤ꒰ㅤMEN AND MINORS DNIㅤ꒱ㅤ☆゙
You didn’t usually meet your friends’ boyfriends. You had your friendship with the girls, but you never cared to know their partners. Not out of arrogance—you simply didn’t want to meet them.
You knew you were better than them.
Still, the smirk on your lips showed that this time, meeting Myung-gi and Min-su, the boyfriends of two of your closest friends, wouldn’t be a waste of time. It would be comical… entertaining, even, to see their faces after your revelation.
As you stepped inside the house, Myung-gi frowned, confused by your presence. Min-su was there too, helping the YouTuber scam people—specifically Thanos.
Or maybe doing something else. You weren’t sure.
“You must be Y/n? Jun-hee’s friend?” you just nodded, still wearing that odd little smile. He almost shrank back, unsettled. “What did you want to talk to us about?”
You let out a cheerful sigh, followed by a soft, short laugh, clasping your hands in front of you.
“I’m not shy…” you began, blushing lightly but never dropping your smirk, nor your gaze. “I’ve pictured your girlfriends naked.”
Myung-gi blinked several times, trying to process whether you had really said that. Sure, his girlfriend was hot as hell, but hearing that from her best friend?? Min-su had the same reaction, though he looked even more shocked.
“Excuse me?”
“Me, Jun-hee and Se-mi had a slumber party last night… remember?” you clicked your tongue like that would remind them of something they hadn’t been invited to.
Myung-gi remembered Jun-hee texting him, saying she was going over to your place. And Min-su remembered Se-mi leaving without explanation late that night. Myung-gi clenched his jaw, his brow furrowing as the probability of Jun-hee cheating on him with you crossed his mind.
“What the hell does that mean?!”
You went straight to the point.
“Me and yours girlfriends playin' dress up in my house.” you leaned back against the wall while both of them froze on the spot. You locked eyes with the YouTuber. “I gave your girlfriend cunnilingus on my couch.” he trembled with rage at the thought. “They’re cute, kawaii, this excites me. I think they really likes me!” his hands flushed red from how hard he was clenching his fists. “ask politely, can I…”
You kept smiling. “Don’t you just love slumber parties?”
“S-Slumber parties…?” Min-su muttered for the first time.
You scoffed.
★ — 1 day ago.
You had invited your two best friends to spend the night at your house. Your plan was simple. Stories, gossip, tea, movies… that was it. But damn, it was your very first slumber party with the two of them! You had never had the courage to accept Jun-hee’s invitations for Girls’ Nights at her place, nor when Se-mi asked you to simply sleep over after a fight with her boyfriend—without anything happening. Because you're shy.
But you just had to wear that pajama.
After tidying up the house, around 6 PM Jun-hee arrived, and you noticed how nervous she looked just seeing you in pajamas.
“You never wear short clothes…” she murmured, her eyes glued to your pajama shorts.
Your outfit was simple, in your usual style. Still, a cropped top and matching shorts.
You gave a small smile, turning off the speaker while Jun-hee sat on the couch. As you turned your back, her eyes trailed down from your shoulders to your butt, her breath hitched.
“Well, it’s hot today.” you shrugged, still facing away, unplugging the speaker.
Jun-hee nodded, licking her lips, her gaze never leaving you. “Yeah, it’s definitely hot.”
You frowned at her words, but quickly ignored it. While waiting for Se-mi to arrive, you and Jun-hee decided to start the newest season of Alice in Borderland, after she changed into her own pajamas—just a shirt and pants. You could feel her eyes on you now and then, hardly paying attention to the series.
You began to feel uncomfortable under her gaze, edging away on the couch, then paused the episode and looked at her, confused. “Why are you staring at me so much?”
Jun-hee’s eyes stayed locked on you, blank at first, like she didn’t know what to say. Before you could repeat the question, her body moved, pinning you down against the couch. “J-Jun-hee?”
“It’s because you’re hot.” she confessed, eyes on your lips, no longer able to resist. “You’re fucking hot, Y/n.”
Then her lips crashed against yours in a hungry, desperate kiss. You froze at first, trying to process, but something about her mouth bewitched you, and soon you were kissing her back, hands gripping her hips, deepening it. Jun-hee’s hands slid from the couch to your breasts, massaging them over the thin pajama fabric. You moaned against her lips when she began grinding down against your lap, her core pressed against yours through the clothes.
When her hands slipped under your bra, pinching your hardened nipples, reality finally sank in.
Jun-hee had a boyfriend.
Your eyes widened as the realization hit. You stopped, gripping her waist.
“What?” she asked, cocky, confused.
“You have a boyfriend.” you reminded her, breathless from the kiss.
She rolled her eyes, squeezing your breasts harder. You bit your lip, letting out a soft whimper. “I don’t care about him.” her face drew closer, gaze sharp. “I want you. Now.”
She kissed you again, and you didn’t stop her this time. She tugged your top up, just enough to free your breasts. She pulled away only to bite your lower lip, then took one of your nipples into her mouth while massaging the other. You slid a hand inside her pants, rubbing her clit over her panties. She moaned at the touch, nipping lightly at your skin.
Just as you were about to slip your fingers beneath her underwear, a knock at the door cut through the moment.
Jun-hee released your breast with a wet pop, and you both shared the same thought.
Se-mi.
Quickly, you both fixed your clothes. Before heading to the door, Jun-hee gave you a soft peck, then slipped into the bathroom to ‘take care of herself’.
You fixed your hair and opened the living room door, finding Se-mi there with a suspicious smile.
“Am I interrupting something?” she asked, her tone laced with sarcasm.
You played dumb. “Excuse me?”
She rolled her eyes, brushing past you and heading straight to your bedroom to change into her pajamas.
Jun-hee came out of the bathroom looking normal enough, but flashing you a suggestive smile. After Se-mi returned, dressed for the night, she didn’t bring the subject up again.
The three of you did the usual slumber party things. Braiding each other’s hair, sharing gossip, finishing Alice in Borderland — Se-mi looked disappointed at the ending. Then came snacks, and later… a little dance rehearsal?
Well, kind of.
Jun-hee put on a song on your bedroom TV, the two of you started dancing, ‘teaching’ Se-mi some moves. Jun-hee, once a K-pop idol, had the natural grace for it. Se-mi had been a vocalist and guitarist in a high school rock band. And you? You were just the ‘simple friend’ who had met them by chance one day while working at a café.
You didn’t really think you had any dancing skills — too shy for that.
That’s what you thought. Jun-hee and Se-mi disagreed.
As you rolled your hips, trying something sensual, both girls’ eyes locked onto you. Sometimes drifting to your breasts bouncing to the beat, sometimes to your perfect face. At one point in the song, their self-control snapped. Se-mi grabbed your hips from behind, while Jun-hee took hold of your waist in front of you. You froze, confused and nervous. “G-girls…?”
“You dance so well…” Jun-hee murmured, her hands sliding up to your breasts again. “I can already imagine you grinding on my lap while I fuck you with a strap.”
Your eyes went wide in shock, your face heating up. Jun-hee had never said something that obscene before. “J-Jun-hee?”
Then you froze again when you felt a hand squeeze your ass, reminding you that Se-mi was right behind you. Her breath brushed against your neck, sending delicious shivers down your spine.
“See? You’ve even made her go wild.” Se-mi whispered in your ear, giving your ass another squeeze.
You were speechless, trapped between two burning bodies. Then Se-mi’s other hand slid inside your shorts, a finger grazing your folds through your panties.
“S-Se-mi..?” you weren’t sure if it came out as a moan or a plea.
Your mind was a mess. But one thing was clear.
You wanted them.
Noticing your reaction, Jun-hee exchanged a look with Se-mi, who gave a small nod. Jun-hee stepped back while Se-mi gently pushed you onto the bed. You barely had time to react before the former rockstar climbed over you, hands roaming your body, lips crashing onto yours with far more hunger and lust than Jun-hee’s kiss had carried.
Meanwhile, the ex-idol reached into her bag, pulling something out before walking back to the bed, watching as Se-mi devoured your mouth. When air became scarce, Se-mi finally pulled away, and you turned your head toward Jun-hee — who was holding a 7-inch purple strap-on. She smiled softly, but made no move to put it on.
“We’ll use it after we’ve tasted you first.” Se-mi answered your unspoken question, kneeling between your legs and spreading them open, even as you tried to close them in embarrassment. “Don’t be shy now, princess.”
You took a deep breath, bracing yourself for what was to come, shedding the last of your shyness.
And honestly, at this point, you really did want to have fun with your friends tonight. Their boyfriends wouldn’t mind, right?
“You look exhausted, and we haven’t even started yet.” Jun-hee teased lightly, placing the strap on the bed just to slip out of her pajamas.
You couldn’t help but let your eyes roam over her slender, feminine, beautiful body. Jun-hee smirked when she felt your gaze, while Se-mi slid down your shorts and panties, biting her lip at the sight of your already dripping pussy.
“On our hands and knees.” Se-mi ordered, her eyes never leaving your soaked core.
You licked your lips, obeying, getting on all fours on the bed. Jun-hee took the chance to sit right in front of you, her pussy perfectly lined up with your face.
“Eat me…” she whispered low, but clear, guiding your head with her hand. “I want to feel your tongue working on me.”
A moan escaped your throat instantly at her words, right as Se-mi dragged her fingers along your slick folds. She then pulled them back, licking them clean, savoring your taste.
“Delicious.” she murmured, before sliding a finger into your tight entrance.
You cried out loudly, though the sound was muffled when Jun-hee pressed your face against her heat. A muffled noise left your lips as your tongue parted her folds, tasting her. Jun-hee closed her eyes, soft moans slipping out as you devoured her, teasing her clit before plunging your tongue inside her entrance, your hands gripping her thighs to keep her in place.
Meanwhile, Se-mi pumped her single finger into your needy hole with precise thrusts, her pace fast but not too deep—just enough to make your body squirm and silently beg for more. Her other hand gripped your ass, squeezing hard enough to leave marks on your skin.
“S-Se-mi… f-faster…” you moaned against Jun-hee’s core, your words sending vibrations straight into both of them.
Jun-hee tangled her fingers in your hair, controlling the rhythm of your tongue on her pussy. The action only pushed you to take her further, sliding one finger slowly inside her entrance—careful, gentle, not wanting to hurt her. Jun-hee choked on her moans, yanking your hair harder.
Se-mi smirked at the sight, rewarding you by sliding in a second finger, fucking you faster, deeper. You were torn between moaning and pleasing Jun-hee, but after copying Se-mi’s actions—sliding two fingers into the former idol— Jun-hee didn’t last long. She came undone in your mouth, releasing your hair. Se-mi glanced at you before slipping her fingers out of your soaked cunt. You whined at the loss, dropping onto your ass on the bed, staring at her in confusion. But before you could speak, she popped her fingers into her mouth, sucking them clean, savoring your taste once again.
“You taste divine,” she murmured after licking her fingers, lowering herself again as she spread your legs wide with her hands. “just as sweet as I imagined.”
Then you felt the cool metal of her tongue piercing glide through your folds, tracing a slow, wet stripe before she pushed her tongue deep inside you, her nose pressing deliberately against your clit. Your head fell back, a cry leaving your lips at the new pleasure, when something hard and plastic nudged against your cheek. You turned your head, only to find Jun-hee calmly strapping on the toy. She caught your gaze, smiling as she knelt on the bed, stroking the strap as if it were truly her cock.
“Take what you can, baby.” she winked, tapping the toy lightly against your lips.
When you only moaned instead of obeying, Se-mi’s nails dug into your thighs in warning, hard enough to leave marks later.
“Didn’t you hear, whore? Obey Jun-hee!” she snapped before diving back between your legs.
Her filthy words made you whimper, heat coiling even tighter in your belly. You obeyed, wrapping your lips around the strap, sucking from the base before sliding down as much as you could take. Jun-hee groaned at the sight, her hands cradling your head as she brushed strands of sweaty hair from your face.
“Fuck, you look so gorgeous like this, dirty girl,” she moaned, fighting the urge to thrust and force your throat to take the toy she’d been gifted on a birthday. “so perfectly submissive.”
You moaned around the strap, looking up, your arousal spiking as her hungry gaze locked with yours.
Your pussy clenched around Se-mi’s tongue, your orgasm tearing through you. Se-mi didn’t stop, greedily lapping up what she could of your release before finally pulling back, wiping her mouth with her pajama sleeve as she watched Jun-hee withdraw the strap from your lips.
“You actually managed to be a good girl.” Se-mi smirked, leaning in to trail kisses along your neck. “You deserve a reward. You don't think, Jun-hee?”
Jun-hee nodded, one hand sliding up to grope your breast.
“Spread your legs wide, princess” Jun-hee instructed, switching places with Se-mi.
The former rockstar stripped off the rest of her clothes, and your eyes inevitably followed—her body was slim, but more toned, probably from working out.
Jun-hee spread your thighs apart as she moved between them, one hand guiding the toy to your soaked entrance. Behind you, Se-mi began teasing your breasts, whispering filth into your ear while you whimpered.
“Shhh, you can take it, baby."
Jun-hee pushed in the tip slowly, her hands sliding down to grip your thighs, holding them open for her. After hearing your soft sounds, she rolled her hips forward, burying the rest of the strap deep inside your pussy.
Your back arched as a loud moan tore from you, hands searching for something sturdier than just the sheets to hold onto. “J-Jun-hee–”
“You can handle it,” – she replied softly, her hands drifting down to your ankles. “I know it, babygirl.”
You tried to focus on Se-mi’s hands kneading and massaging your breasts, her mouth kissing and sucking along your neck, while Jun-hee began to move—gentle thrusts, not too deep, but steady. A low moan escaped your lips as you shut your eyes, lost in the double pleasure, sweat dripping as time passed. Se-mi turned your face with one hand, capturing your mouth in another kiss, swallowing your sounds.
“F-Fuck, I can feel how tight you are. Swallowing my strap like such a good girl.” Jun-hee murmured between filthy words, her self-control starting to slip again.
You could only let out muffled sounds into Se-mi’s mouth, savoring your taste. Jun-hee blew her bangs out of her face, her thrusts growing firmer, deeper… faster. Each smack of skin made you choke into Se-mi’s lips, the knot in your belly tightening.
“You close, princess?” Jun-hee asked, noticing how your back arched even harder.
“Mmh, y-ye–” you tried, but Se-mi’s lips cut off the rest.
Still, Jun-hee understood. She sped up, her thrusts driving you harder until Se-mi finally broke the kiss when your moans grew louder, leaving both women hungrier for you. This orgasm wasn’t weak—it was intense. The best one you’d ever had. Jun-hee slid the strap carefully from your pussy, while Se-mi pressed one last kiss to your neck before pulling back.
You let out a long sigh, eyes still closed, trying to process what just happened. Then, something cold was set on your belly. You blinked open, only to widen your eyes—a dildo, still turned off, resting on you.
“Already tired? We haven’t even started.” Se-mi teased, helping Jun-hee unstrap.
You swallowed hard. Tonight was going to be long.
ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ ⁺⠀ 𝜗ৎㅤㅤㅤ♡ㅤㅤㅤ𝜗ৎ ⁺
You woke up sore all over, exhausted, but completely satisfied. Se-mi and Jun-hee had taken care of you after the wild night—even gave you a bath. Still, guilt lingered that you hadn’t given Se-mi any relief.
Limping your way into the kitchen, you went straight to the fridge, not paying attention to your surroundings. You poured cold water into the first glass you saw and downed it, only then glancing around.
“Good morning.”
You almost choked when you spotted Se-mi sitting at the dining table, sipping what was probably warm milk. She was in just a bra, and you couldn’t tell if she was naked from the waist down.
“Good morning…” you muttered, setting the glass in the sink and putting the water bottle back in the fridge.
“Still sore?” she asked, watching you closely, concern flickering in her eyes.
“A little. Yesterday was… wow.” you murmured, blushing.
“Yeah. I agree. But was hot.”
Turning to face her, you leaned back against the counter.
“But, like… aren’t you dating Min-su?” you asked carefully. “Why did you cheat him… with me?”
Se-mi smirked, taking another sip of her milk. A bit of the white liquid clung to her piercing, and it made your stomach flip—it reminded you of how she’d eaten you out the night before.
“Min-su hasn’t exactly been the best boyfriend lately.” she shrugged, as if that answered everything. “Besides, I’ve always liked you better…”
Your cheeks burned. Se-mi used to have a reputation for being a carbon copy of every straight guy cliché, but ever since you met her two years ago at the café, your view had shifted. She wasn’t like them.
She was better.
Although, yeah—some of her flirting habits did look suspiciously like straight-boy tactics.
“But you still cheated him…”
“Didn’t seem to bother you last night.” She had a point. Last night you’d barely remembered Min-su, Myung-gi, or even your ex.
“Shit…” you muttered, knowing she was right.
Her grin widened as she set the glass aside. “Come here.” she patted her lap; you couldn’t see it, but the movement was obvious. “Sit on my lap.”
You hobbled toward her, sore legs slowing you down. When she came into clearer view, you bit your lip. She was already strapped, wearing the same harness from the night before, waiting for you.
“I wanted to use this on you yesterday, but you got tired so fast. So…” she grinned, guiding your hand before pulling you onto her lap. “Come on? Please?”
You sighed, shaking your head, but still unbuttoned your shorts, sliding them and your panties down before straddling her. Se-mi helped, one hand guiding the toy into place, the other gripping your hip. Slowly, you sank onto her strap, biting your lip to keep quiet so you wouldn’t wake Jun-hee.
You owed Se-mi this moment alone.
Her hands clamped firmly on your hips, helping you ride her lap as your hands dug into her shoulders, soft moans spilling out. The soreness in your legs faded under the rush of pleasure. “Y-you can go faster.”
Her eyes searched yours, checking if you meant it. When she saw no hesitation, Se-mi started meeting your thrusts with her own, lifting her hips each time, her grip controlling your pace. To swallow your moans, she used her favorite trick—crashing her lips into yours until you were breathless. The muffled sounds spilling from your mouth only drove her crazier, making her want to skip work and fuck you all day.
Maybe Jun-hee would even join in.
At one point, you slid a hand into her hair, tugging. Somehow, that knocked the breath out of her—and her control.
Her hands shifted to your ass, lifting you in her lap until your legs wrapped around her waist. Se-mi stood, placing you on the table, pounding into you harder, her tongue tangling with yours. You were gasping, overwhelmed by the pleasure, walls clenching tight around the toy as your orgasm neared.
But then—you made the mistake of bracing a hand on the table, knocking over her glass of milk. It shattered on the floor, loud enough for anyone in the bedroom to hear.
Jun-hee.
Se-mi and you froze, staring at the shattered glass in silence. The bedroom door slammed, and Jun-hee ran to the kitchen—barefoot, one slipper in hand—worried, half-asleep, and apparently convinced a burglar had broken in.
“What’s going on?” she asked, rubbing her eyes, and when her vision focused, she raised her brows in surprise. “You two are starting the day without me?”
Se-mi scoffed, rolling her eyes playfully. “You were starting the night without me yesterday.”
Jun-hee dropped the slipper on the floor and crossed her arms, looking offended. “You’re the one who was late.”
“Me?”
“Yes?”
You rolled your eyes as their stupid argument dragged on, your orgasm forgotten and the soreness coming back.
“Who’s making the breakfast?” you asked, cutting into their bickering.
Jun-hee and Se-mi exchanged a glance, then both looked back at you smugly. “You are the breakfast.”
You blinked, then moaned when Se-mi started thrusting the strap on inside you again, fast and merciless. Jun-hee came closer, smirking.
“By the way Se-mi, you’re the one cleaning the floor.” the former idol said.
“Shut up.”
ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ ⁺⠀ 𝜗ৎㅤㅤㅤ♡ㅤㅤㅤ𝜗ৎ ⁺
Se-mi grumbled as she carefully swept up the shards of glass from the floor, ready to mop up the milky mess next.
Jun-hee laughed at the scene, holding back the urge to take a photo, and walked over to the living room. All of you were already dressed… again, without pajamas. Se-mi was going home, while Jun-hee was heading to work. You didn’t have an actual job right now, since the former café had closed, but you planned to look for one once they left.
While scrolling through your phone on the couch, Jun-hee suddenly jumped onto the couch beside you. You stared at her, watching as she snatched your phone and set her bag on the table.
“I want a goodbye.” she murmured, moving to sit on your lap.
“Jun-hee…”
“Last time today.”
You sighed, placing your hands on her waist as you both started kissing. Of course, it didn’t take long before it became something wilder, this time with you taking the lead. You pushed her onto the couch, pulling down her pants along with her panties. Jun-hee placed one hand on your head and the other over her mouth. She wasn’t going to let Se-mi interrupt. (Jealousy or…)
You buried your face between her legs, sucking her clit while running your fingers over her folds. Jun-hee bit a finger to keep from moaning loudly, thrusting her hips toward you. You slid your tongue through her folds until reaching her center, licking and plunging your tongue deep inside.
Se-mi finished in the kitchen and walked into the living room, shaking her head at the sight, while Jun-hee flipped her the bitten middle finger. The rockstar smiled before heading to the bedroom to grab her bag.
When the orgasm hit Jun-hee, you cleaned her up with a towel that, curiously, was nearby. She dressed again, giving you one last peck before leaving with her bag. Se-mi came back from the bedroom carrying her own bag and went straight for the door. You whistled. “No goodbye?”
“Who knows, maybe I’ll show up tonight?” she winked, opening the door and leaving.
You exhaled deeply, sitting on the couch, unsure of what to do next.
Or maybe you did.
Myung-gi and Min-su…
They would be shocked if they found out.
★ — Returning to the scene.
At your question, the YouTuber took a deep breath.
“Do you have anything else to tell?!” he asked sharply.
You clicked your tongue, pretending to recall.
“Oh yes!” you smirked, glancing at Min-su. “Se-mi said she prefers me over you.”
The guy didn’t even know how to react. Myung-gi huffed, dragging him back into the house, leaving you alone on the street.
“I just ruined two relationships,” you thought, walking down the streets, smiling. “And that’s because I’m shy. Imagine if I wasn’t…”
