The rest of the girls had finally filed out of the practice room, laughing and chattering about late-night snacks and how sore their legs were. You waved them off with the usual reminders—hydrate, stretch, sleep—and locked the door behind the last staff member. The large mirrored space felt quieter, almost intimate now that only the low hum of the air conditioning remained.
Except Sana hadn’t left.
She was still sitting on the floor against the mirror, legs stretched out in front of her, sipping from a water bottle. Her cropped practice top clung to her damp skin, and those tiny shorts rode up her thighs. She looked up at you with that signature playful smile.
“Manager oppa… you’re not going to kick me out too, are you?” Her voice was sweet, but there was a husky edge to it. “I think I need extra help with the bridge. My hips keep doing the wrong thing.”
You raised an eyebrow, leaning against the wall across from her. “Everyone else managed to get it after the last three runs, Sana.”
She pouted, pushing herself up gracefully and walking toward you. Each step was deliberate, hips swaying just a little more than necessary. “But I’m not everyone else. You always say I need special attention.” She stopped right in front of you, close enough that you could smell the faint cherry scent of her lip gloss mixed with sweat. “Don’t you?”
Your jaw tightened. “Sana, it’s late. You should head back to the dorm with the others.”
She tilted her head, eyes sparkling with mischief as she placed one hand lightly on your chest. “Then why did you lock the door, oppa? And why have you been staring at me all night? During the waist rolls… when I was on the floor doing those splits… even when Jihyo was talking to you. I saw everything.”
You let out a slow breath. “You’re playing a dangerous game.”
“Am I?” She stepped even closer, pressing her body against yours. Her fingers traced a slow circle over your chest. “Or are you finally going to stop pretending you don’t want to fuck me? I’ve seen the way your eyes follow my ass when I walk past you in the hallway. The way you shift in your seat when I ‘accidentally’ sit on your lap in the van.”
Her hand slid lower, palming the growing bulge in your sweatpants. “Mmm, see? He doesn’t lie like you do.”
“Fuck, Sana…” you groaned, hands finally grabbing her waist and pulling her flush against you.
She gasped softly, then let out a delighted little laugh that turned into a moan when you kissed her hard. She tasted like cherry and sin, tongue immediately sliding against yours with practiced eagerness.
“Mmm—yes,” she breathed between kisses, hands already tugging at your shirt. “I’ve wanted this for so long. You have no idea how wet I get when you scold me during practice. ‘Sana, focus.’ ‘Sana, stop teasing.’ It makes me want to drop to my knees right there in front of everyone.”
You pushed her back against the mirror, the cool surface making her shiver. “You’re such a fucking tease, Sana.”
“I know,” she giggled breathlessly, nipping at your bottom lip. “And you love it. Look how hard you are already… all for me.” She sank to her knees smoothly, never breaking eye contact as she pulled your cock free. Her eyes widened with genuine hunger. “Oppa… you’re so thick. Bigger than I imagined when I touched myself thinking about you.”
She gave the head a slow, teasing lick, humming happily at your sharp inhale. “Tell me what you want. I want to hear you say it.”
Your hand threaded into her soft hair. “Suck it, Sana. Show me how much you’ve been thinking about this.”
“Yes, oppa~” She moaned around you as she took you into her warm, wet mouth, cheeks hollowing. The wet, filthy sounds echoed in the empty practice room. She bobbed her head eagerly, one hand stroking what she couldn’t fit, the other slipping between her own thighs.
“Fuck… just like that,” you groaned, hips twitching. “You look so pretty with my cock in your mouth. Such a good little slut for your manager.”
Sana pulled off with a wet pop, stroking you fast while she looked up with glassy eyes and flushed cheeks. “I’ve touched myself thinking about this every night. In the dorm, in the van, even in the bathroom during schedules. Imagining you bending me over the makeup table and fucking me until I can’t dance tomorrow. Would you like that? Fucking me right before a fansign so I have to smile with your cum dripping down my thighs?”
You pulled her up, spinning her around to face the mirror. “Watch yourself,” you ordered, yanking her shorts and panties down in one motion. She was soaked, glistening under the practice room lights.
Sana braced her hands on the glass, arching her back and pushing her ass toward you. “Please, oppa… I need it. Don’t be gentle. I’ve been bad, teasing you every day. Punish me.”
You rubbed your cock along her slick folds, teasing her clit until she was whimpering. “Tell me how much you want it.”
“I want it so bad—ahh!” She cried out as you thrust in deep, filling her in one smooth stroke. “Yes! Fuck me, Manager-nim. Use me. I’m your toy tonight.”
The mirror showed everything—her face twisted in pleasure, tits bouncing under her top with every hard thrust, your hands gripping her hips. Sana’s moans filled the room, filthy and unrestrained.
“Harder—please— I’m yours tonight. Just yours.” She reached back, nails digging into your arm. “Fill me up. I want to feel you leaking out of me when I leave. I want to sit in the van tomorrow and feel you inside me the whole ride.”
You fucked her relentlessly against the mirror, one hand slipping around to rub her clit. “You’re so fucking tight, Sana. So wet for me.”
“All for you—fuck—right there! Don’t stop!” Her voice cracked as she came hard, walls clenching around you, eyes locked on your reflection the whole time. “I’m cumming… oppa, I’m cumming on your cock!”
You followed right after, burying yourself deep and groaning her name as you spilled inside her.
You stayed buried inside her as you both caught your breath, hearts still racing. Sana’s legs trembled slightly, but she leaned back against your chest with a satisfied, lazy smile, still watching you both in the mirror.
“Mmm… that was even better than I imagined,” she murmured, voice husky and soft. She reached up to cup your cheek, turning her head for a slow, tender kiss. “You came so much… I can feel it leaking out already. Such a good, generous manager. Are you always this pent up, oppa? Poor thing… working so hard to keep all nine of us in line while we drive you crazy every day.”
You kissed her neck, still breathing hard. “This can’t happen again, Sana. If anyone finds out—”
She laughed softly, a bright, airy sound that made her clench around you playfully. “Oppa, you’re so cute when you’re worried. But we both know this is happening again. Tomorrow night. Maybe the night after. Maybe every night.” She rolled her hips slowly, savoring the way you twitched inside her. “And eventually… the others are going to notice how stressed you look. They’ll want to help too. Especially Nayeon and Momo. They’ve been talking about you more than usual lately.”
You raised an eyebrow, hands still gripping her hips. “You’ve been talking about me with them?”
“Of course,” she said with a mischievous grin, turning in your arms to face you properly. Her fingers traced lazy patterns on your chest as your cum slowly dripped down her thigh. “We’re TWICE. We share everything. Including our handsome, hardworking manager who tries so hard to be professional while we all want to ride him senseless. Last week in the dorm, Jihyo asked me if I thought you’d be gentle or rough. I told her you’d be perfect either way.”
Sana kissed you again, slower this time, then rested her forehead against yours. “But tonight was mine. I wanted you first. And I got you.” Her voice dropped to a whisper. “Next time, I might invite someone to watch… or join. Would you like that? Watching me eat Momo’s pussy while you fuck me from behind? Or maybe all of us taking turns on our knees for you after a long schedule?”
You swallowed hard, already feeling yourself twitch inside her again at the thought.
Sana giggled, clearly feeling it. “See? Your body is more honest than your mouth. You like that idea, don’t you? Greedy oppa… one taste of me and you’re already thinking about the whole group.” She gave you one last soft kiss before slowly pulling off you, a thick trail of your combined release running down her leg. She didn’t bother wiping it away immediately.
Instead, she scooped a little with her finger and brought it to her lips, tasting it with a happy hum. “Delicious. Next time I want it in my mouth. Or on my face. I want to wear it under my makeup during rehearsals.”
You helped her adjust her clothes, but she kept stealing little kisses and pressing her body against yours.
“Thank you, oppa,” she whispered sweetly, batting her lashes as she fixed your shirt. “I’ve never cum that hard during practice before. My legs are still shaking. How am I supposed to walk straight tomorrow? Everyone’s going to ask what happened to me.”
She leaned in, lips brushing your ear. “And when they do… I’ll just smile and say our manager gave me some very special one-on-one training.”
Sana stepped back with a wink, grabbing her bag. “Walk me to the car? I want to hold your hand the whole way… and maybe tease you a little more on the ride back. We still have twenty minutes alone in the van.”
As you both left the practice room, her fingers laced with yours and she leaned her head on your shoulder.
