    [Im Yeojin has sent a message:]

    Oppa!

    Come by the practice room.


    You push open the door to the practice room, the formerly muted melody from the music greeting you full force. Yeojin turns her head to the entrance, smiling brightly as she hops on the spot at your entrance.

    “Oppa, you came!”

    “Yeah, of course I did. What, what surprise do you have this time?” You close the door behind you and walk over to the petite idol. Yeojin runs to the computer, tapping a few keys to pause the music.

    “What day is it today?” Yeojin has a teasing grin on her face as she gives you an impromptu test. She leans forward, hands on her hips as she scrunches her nose at you.

    “Your birthday, of course.” You know you’ve passed with flying colours when Yeojin’s jaw drops. Her entire face lights up as she barrels into you for a tight hug.

    “You remember!” Yeojin hops up and down in your embrace, her entire being buzzing with joy. You peck Yeojin on the forehead.

    “How can I forget my girlfriend’s birthday?”

    “That’s right, you can’t! Or I’ll kill you!”

    You laugh at Yeojin’s adorable threat. Yeojin cannot kill anything at any size, let alone you, but you humor her anyway while you ruffle her hair. “Fine, fine.”

    “Oh, I didn’t tell you, didn’t I?” Yeojin leaves your embrace with a step back. A look to the left, then to the right, and Yeojin giggles as she takes the off-shoulder long-sleeved top she has on. Underneath, all she has is a black thin spaghetti-strapped crop top that shows off the bare skin of her shoulders and her well-defined clavicles. A hint of her cleavage peeks over the cutting of said top.

    You definitely do not stare, no you don’t. At least, you don’t after she speaks.

    “I took the liberty of choosing my birthday gift.” Yeojin folds her arms as she puts her weight on her left foot, scrunching her nose. Her chin rests on her left index finger and thumb as she hums.

    “What is it you want?”

    “Sex.”

    Huh?

    “Sex. With me. Here. Now.”

    Everything slows. Your mouth opens and closes, akin to a fish, as you try to process what you’ve heard. Yeojin just stands silently, a grin on her face. Subtly, she shifts to remove her shoes and put them aside while you’re spaced out.

    “Maybe you need some incentives to come to a decision.”

    Yeojin pulls her top up. Her petite chest is on full display, the nipples taut and stiff. You rush to cover her up as you glance around the glass walls of the practice room. Yeojin leaps away from your attempts as the black top is successfully stripped off her body and flung aside.

    “Are you fucking crazy, Yeojin? You can’t do that!”

    “Hell yeah I can. Don’t act like you don’t love it, we’ve talked about this.”

    You know the exact conversation she refers to. Months back, you and Yeojin found out about your shared exhibitionism kink, and you’ve never mentioned anything else about it since then. For Yeojin to use that information against you now was definitely shocking, but you’d be damned if you said you weren’t aroused.

    “What if people see you? What if people see us?”

    “No one’s here today. They’re all at some company lunch. We can fuck as loud as we want today.” Yeojin kneads both her breasts, a sultry smirk on her face. She pushes her track pants off her hips, gravity aiding her in her bid to undress. Now, Yeojin stands naked before you, in the middle of the transparent practice room. She steps out of the pool of clothing on the floor then takes a walk around the room. Her journey takes her right in front of you.

    “It feels so good to be naked here, fuck. I’m already so wet just like that.” Yeojin reaches a hand down to her crotch, running two fingers over her slit, showing you the glistening wetness over the tips. Strands of her fluids string between her fingers. She licks her fingers clean, then pulls your pants down. In an instant, Yeojin has your cock out, her hands wrapped around the length as she jerks you off, slowly.

    “Get naked with me and fuck me. Make me squirt all over. You know you want to.”

    She’s right. You do want to. However, even with the reassurance that no one is around, you can’t shake the feeling that you’re being watched. Your eyes roam the corridors around the practice room, looking at each of the vocal rooms on the opposite side. Most of them have their curtains drawn, but you catch a flash of movement when your eyes land on Hyeju’s room. You squint to affirm your perception, but that thought is immediately forgotten once Yeojin’s warm lips wrap around the tip, your shaft sinking into the wet, warm cavern of her mouth.

    Yeojin takes you slowly. She applies a constant suction effect as she blows you. At the same time, she plays with your balls with one hand, the other steadying herself with a grip on your thigh. She makes eye contact with you while she kisses your tip, tongue landing soft strikes on the sensitive underside. You share an intense staredown with her before she breaks it, her free hand on her clit next, two fingers penetrating her sex.

    “Oh, fuck~”

    Yeojin fucks herself with the same rhythm that she uses to blow you. The sensations and sounds from her blowjob and masturbation threaten to overwhelm you—sex in public with your dear girlfriend was as hot as you thought it would be. You field a gaze down, watching Yeojin take your shaft into her mouth over and over. Her tongue swirls around your shaft each time you enter her. The wet muscle sends bursts of pleasure along your shaft. Move your eyes down, and Yeojin has four fingers deep within herself, curling to strike her G-spot with each movement. A mixture of moans fill the room.

    Yeojin teases your cockhead one more time, her tongue on your sensitive underside once more. She jerks you off, her strokes hard and fast. However, to your disappointment, her hand drops from your shaft as she gets up, leaving you hanging.

    “What—Why’d you stop?!”

    “I want to ride you. Now. Strip.”

    Yeojin tugs at your pants as you pull off your shirt. You kick your clothing aside and you lie on the floor, Yeojin straddling you immediately. She strokes your shaft a few more times with her wet hand, preparing you to enter her. Hooded eyes lustfully rake over you as she lines you up with her hole. One drop, and Yeojin impales herself on you, the full length hilting in her. Guttural moans escape her mouth as she fucks herself atop your shaft. Copious amounts of slick leak down your length, lubricating your shaft even further. Yeojin’s tight walls get even tighter when you begin to thrust up into her. Every rise and fall of her hips is met with an opposite motion from yours. Yeojin moans when you bottom out in her, the obscene vocalizations and sounds of sex prompt you to fuck her harder.

    “Oh, fuck, yes, yes, fuck me just like that, fuck me like that where everyone can see, yes!”

    It doesn’t take long before Yeojin’s walls get even tighter, pussy even wetter. Short pants of breath are all Yeojin can manage as she hangs her head forward, eyes squeezed shut as the delicious pleasure nears its peak. You’re not far off either—her blowjob on you earlier already had you close, and now, her pussy would definitely finish you off.

    “Oh, fuck, fuck, fuck, I’m cumming, I’m cumming!”

    Yeojin lifts herself off you, forcing you to drop out of her. She rubs her clit furiously, driving herself over the edge. Before you can even start to complain, Yeojin squirts all over your chest, your abs, and your cock. Stream after stream of Yeojin’s release fires out of her cunt, some leaking down her skin onto your thighs, as she throws her head back, gasps and shaky breaths all she can manage as she rides her orgasm out. When Yeojin finishes, she grabs your wet cock and impales herself with it. Three bounces is all you need before you explode within her, the sight of Yeojin squirting plastered all over your mind and behind your closed eyes. You fill Yeojin with thick white semen, burst after burst of your seed fired deep into her tiny body, filling her womb up. Semen leaks out of the gaps between your connection, and when she lifts herself off you again, more of the pearly white cream drips out of her, staining your skin and the practice room floor.

    Yeojin collapses on the floor opposite you. Both of you are sweaty messes. The bright white light of the LED bulbs on the ceiling reflects off your bodies. Two sets of heavy pants are all that can be heard as both of you catch your breath, trying to regain what energy you have to begin cleanup.


    Son Hyeju sinks to the floor in her practice room, her legs trembling. She rests against the wall, her raven hair falling messily over her face. A few locks of the hair sway from the breeze caused by her heavy panting, though most of the stray strands stick to her sweaty skin. Hyeju raises her wet hand to her mouth. Her lips wrap around her dripping fingers, cleaning them of the fluids staining her skin. In front of her, puddles of her squirt from three consecutive orgasms pool in her vocal room, her curtain drawn open slightly.

    Hyeju’s eyes are locked on Yeojin and her boyfriend as they both lie in the practice room, entirely spent. Hyeju grins when she hits the Stop button on her camera app, the recording of Yeojin’s public sex session saving itself on Hyeju’s phone. Hyeju’s pussy clenches when she thinks back to Yeojin squirting all over her boyfriend. Was his dick that good? Does sex really feel that good?

    Hyeju stares at the mess she made in her vocal room. Her clothing is strewn haphazardly on her chair, hurriedly torn off in order to masturbate in comfort peeping on Yeojin and her partner. She wonders if he caught her watching, and what he might do if she did find out. Would she be invited to join them? The thought of it sends another jolt of arousal through her veins.

    Maybe she should ask Yeojin to let her fuck her boyfriend for her birthday.
