    Author's note

    Left this one in the drafts so long i forgot i never posted it.

    March 24, 2026. The first Japan leg of the Asia tour kicked off in Osaka. tripleS performed at a mid-sized arena, sweaty, loud, electric. Yooyeon shone brighter than usual during “Rising,” her part: eyes half-lidded, lips parted, every hip roll and slow body wave looking less like choreography and more like foreplay set to a beat drop. Fans screamed. Phones recorded. You stood side-stage with the crew, capturing behind-the-scenes clips for the official fancam channel.

    After the encore bows she vanished into the labyrinth of backstage corridors before anyone could congratulate her. You found her ten minutes later in one of the unused green rooms on the lower level, door half-open, lights dimmed to a single vanity bulb.

    She was already naked except for the thin silver choker necklace the stylist had clipped on for the finale look. Kneeling on the ratty couch, back arched, ass presented toward the door like an invitation. Between her spread thighs dangled a small remote-controlled vibrating egg, slick cord trailing out. She’d clearly inserted it mid-change.

    When she saw you she pressed the remote into your palm without a word.

    “New idea,” she whispered, voice still hoarse from singing. “During the whole after-party on the 18th floor suite tonight, this stays inside me. You control the intensity. Every time I talk to someone, staff, dancers, label executives, whoever, you turn it up one level. If I can’t keep a straight face for a full minute at max, you win. I win if I cum right there in the room without anyone noticing. Loser has to do whatever the winner wants for the next 24 hours.”

    She crawled forward, nuzzled your crotch through your jeans for a second like a thank-you, then stood up and slipped into a fresh oversized hoodie + bike shorts combo. The egg’s remote fit perfectly in your pocket. She kissed you once, soft, almost pure, then walked out ahead of you toward the elevator, hips swaying just enough to remind you what was buzzing quietly inside her at level 1.

    The suite was already alive when you arrived: soju bottles sweating on tables, Bluetooth speaker thumping low R&B, maybe thirty people total, backup dancers, lighting techs, a couple of Japanese promoters, the tour manager half-drunk already. Yooyeon floated through the room like nothing was wrong. Laughing at jokes, clinking glasses, posing for selfies.

    You waited until she was mid-conversation with two backup dancers, the same ones from the hallway a few days earlier.

    Click. Level 2.

    Her smile didn’t falter, but her free hand drifted to press lightly against her lower stomach. She laughed a little too brightly at something one of them said.

    Click. Level 3, while she was hugging the promotions girl goodbye.

    Yooyeon’s knees dipped for half a second. She covered it by pretending to fix her sock, then straightened, cheeks pinker now.

    You let her recover for ten full minutes. She was good, damn good, chatting animatedly with the tour manager about tomorrow’s Nagoya setlist, voice steady.

    Then, when she leaned over the low table to pour someone a drink, ass perfectly framed in those tight bike shorts, you bumped it straight to level 6.

    Her breath hitched audibly. She froze for two heartbeats, drink sloshing. The guy next to her asked if she was okay. She flashed that trademark rabbit smile.

    “Just… cold drink brain freeze, haha.”

    But her thighs were trembling. You could see the tiny rhythmic pulses under the fabric.

    Level 7.

    She excused herself to the balcony “for air.” You followed at a distance.

    Outside, city lights glittered below. She gripped the railing, forehead pressed to the cool glass door, whispering,

    “You’re evil… it’s pulsing so deep… I’m dripping down my legs already…”

    You stepped behind her, hand slipping under the hoodie hem to feel for yourself. Soaked. The egg’s low buzz vibrated against your fingertips through her shorts.

    “Level 8,” you murmured, pressing the button.

    Yooyeon’s moan was barely muffled against her own arm. She rocked back against nothing, chasing pressure.

    “Fuck—fuck—I’m gonna—wait—wait—”

    She spun around suddenly, eyes wild and pleading.

    “Inside. Now. Bathroom. Please.”

    You dragged her through the party, her walking bow-legged, smiling at everyone like the perfect idol, until you reached the guest bathroom at the end of the hall.

    Door locked.

    She shoved her shorts and panties down in one motion. The egg slid out with a wet pop, still buzzing furiously. She turned it off, set it on the counter, then bent over the sink, hands braced, looking at you in the mirror.

    “No more games. Fuck me hard. Right here. While they’re all out there drinking and laughing. Make me scream into my own hand so no one hears.”

    You didn’t hesitate. Jeans open, inside her in one thrust—hot, swollen, fluttering from thirty minutes of denied stimulation. She bit down on her knuckles immediately, eyes rolling back.

    “Harder—please—wreck me—fill me so full I leak through the shorts on the way back to the room~~”

    You gave it to her. Fast. Deep. The sink rattled. Her muffled cries vibrated against her fist. When she came it was violent, whole body seizing, walls clamping so tight you followed seconds later, pumping everything deep while she whimpered your name around her fingers.

    Afterward she stayed bent over, breathing ragged, cum slowly dripping down her inner thigh. She reached back blindly, scooped some with two fingers, brought them to her mouth and sucked clean with a contented hum.

    “Best loss ever,” she panted, grinning at her own reflection, hair wrecked, lips swollen, eyes still glassy with afterglow.

    She pulled the shorts back up (no panties), let the hoodie fall to cover the wet spot already forming, then turned and kissed you slow and filthy.

    “Tomorrow night in Nagoya… we do the same. But this time if i lose I have to wear the egg during soundcheck. And if I win…” She traced a finger down your chest. “You have to let me give you head in the van on the way to the venue. Windows down. Staff in the front seats. Think you can stay quiet?”

    She opened the door a crack, peeked out, then slipped back into the party like she’d just gone to fix her makeup.

    You stayed behind a second longer, watching her rejoin the crowd, laughing, glowing, the faint wet sheen on her thighs catching the light every time she moved.

    She glanced back once. Blew you a kiss.

    Then turned the egg remote on again, level 1, and tucked it into her hoodie pocket.

    Game’s not over.

    Just paused.
