Soundproof

You find yourself in the WM Entertainment building, waiting on Binnie to finish recording her part in their latest song. You wander down the hallways, greeting staff members as you run into them. Your relationship with Binnie is a bit of an open secret, but you're not sure how much is known of your "activities" with the other members.

"Hi oppa!" You hear a loud cheery voice ring down the corridor, causing you to lift your head from your phone. You see Hyojung waving at you, brightly smiling and beckoning at you. She's dressed simply, wearing a striped blue blouse and tight white pants.

"Hey Hyojung, you finish your recording already?"

"Yup, I was first! Now I'm just waiting on the other members now, they're further down the hall."

"Got it, what are you up to?"

"Just playing on my phone in this recording studio, it's nice and quiet and no one's using it."

"Sounds good, have fun!"  You make to leave Hyojung alone, giving her some time to herself. But she grabs you before you can leave.

"Wait, can you watch over my things for me? I have to go use the restroom real quick."

"Uh sure, take your time." You fiddle around on your phone, leaning back and relaxing on the couch.

"Ooh oppa what are you playing, is that a new game?" You almost jump out of your seat when Hyojung loudly announces her return.

"You're so loud!" You exclaim at her, holding your hand to your ear, pretending that it's bleeding.

"Oops sorry... anyway, I was thinking, we have time anyways, how about we enjoy ourselves?" She hands you a small nondescript remote before sitting down next to you. You press the "Start" button, and it doesn't take long for you to figure out what it starts, and what she was doing in the restroom.

"Ahh!" Hyojung squeals, her hands going straight to her crotch as she tenses in pleasure. You quickly press the "Stop" button and look at the studio door, making sure it is closed. Lucky for you, it is.

"Are you crazy, in your company studio?"

"Oh don't worry, it's fine, there aren't any cameras in here if that's what you're afraid of. Come on, help me out, hmm?" She pleads at you brightly, the ever-cheerful leader seemingly very daring as well.

"Okay, try to keep it down." You press the "Start" button again. Hyojung squeals once more, rubbing her thighs together, her whole body clenching against herself, her focus centered on the pleasure coming from her crotch. For several minutes you let the vibrator in her go, causing Hyojung to lean back on the couch, grabbing the back of it with her arms, bucking herself up in the air.

"Ahh that's good!" With a loud cry she thrusts her hips off the couch before crashing back on it, her legs twitching. She looks at you with a goofy smile, panting heavily.

"Did you cum already?"

"Just a small one, keep going!" You look around, a wicked idea entering your mind.

"No, you're too loud, go in there." You help Hyojung up before pushing her into the soundproof recording booth.

"There, now you can scream all you want." You wink at her before closing the door. With that you press the "Speed+" button on the remote repeatedly, making full use of the motor in Hyojung. You watch her jaw drop open, her neck muscles straining and tensing as she screams in the soundproof booth. Her hands grip the lyric stand tightly, in danger of shaking the stand to pieces while she shivers in orgasm. Her face gets redder and redder, seemingly gasping for oxygen, a bit of drool leaking from the edge of her mouth. You decide to let the poor girl have a rest, and Hyojung slowly sinks to the floor, holding on to the stand for support. You sit yourself in the producer chair and hit the mic button, letting you talk to her in the room.

"How was that?" You stand up to see her, and Hyojung gives you the "Okay" sign, her face tired but still smiling. She tries to say something, but you can't hear her - she motions for you to put on the headset on the table.

"Can you hear me now? That was great! Keep going!" Her energy and libido are far higher than you thought. You keep the headset on while turning on the vibrator again, and you immediately regret your decision.

"Yes!" Hyojung's shrill scream pierces your ear before you knock the headset off your head. Your ears still ringing, you watch her hands busy themselves on her body, one hand unbuttoning her blouse while the other works on her pants, unbuttoning them and immediately sliding a hand underneath her panties. Soon she is a sexy mess, her blouse falling off her shoulders, revealing her pink bra and generous cleavage to you. Her hips hump at the air uselessly, her other hand in her panties, rapidly rubbing her clit.

With a sharp jerk and sudden stillness, you see Hyojung cum again, her mouth hanging open, definitely screaming her pleasure into the room. You keep her at the edge of orgasm, playing with the speed of the vibrator as her expression almost freezes in place, her body continuously feeling waves of unending but variable pleasure. Watching her squirm in front of you, you feel your own arousal rising and you enter the room, quickly dropping your pants and boxers to the floor. Hyojung gets your message and tries to follow suit. You don't give her that chance however, and you pull her panties down, trapping them at her knees instead. You take a moment to pull the vibrator out of her before you push her against the booth window, slipping yourself into her slick heat.

"Oh god..." A loud moan escapes her lips as you replace the object in her with a much bigger and meatier tool. Hyojung was tight but wet, her multiple orgasms more than preparing her for your penetration. She was very sensitive, and loud screams punctuate the air every few pumps, her pussy contracting around you sharply every time. She was way too loud for you, and you find yourself cupping a hand over her mouth, keeping it shut as you rip more shrieks of delight from her body. You take the opportunity to feel her up, your other hand diving under her bra, groping her soft and bountiful chest. You squeeze her breast tightly for more grip as you pump into her, the sounds of flesh meeting flesh taking the place of Hyojung's muffled cries.

"Oh shit!" You eyes widen as you see the door handle into the studio turning. Quickly you force the both of you down to your knees, and Hyojung ends up on all fours as you take her from behind. You try to stay silent and still, hoping that whoever enters the studio would just leave - the company might just end you if they caught you balls deep in the leader of their girl group. Said leader has other ideas though, as she begins backing herself on your cock, trying to get you to start moving again. Her walls prove too enticing for you, and you begin fucking her hard and fast. With your hand no longer over her mouth, Hyojung wails get louder and louder, the woman rocketing to her next orgasm. You grab her dark brown hair with one hand, pulling her head back, hoping that would make her quieter. She looks back at you, grabbing the hand on her head with one of hers and guiding it to where she wants it... it ends up at her throat.

"Are you sure?" You stop pushing into her to ask, incredulous.

"Don't stop, I'm so close!" She completely ignores your question, begging you to keep going instead. Your hand keeps a firm but gentle grip on her throat, but that proves futile when she pushes your hand further against her skin, feeling her fingers crush against yours, trying to get you to choke her. She gives you a toothy smile, clearly drunk on pleasure. You feel your orgasm rising, and your grip slowly but surely tightens around her neck as you thrust into her faster and faster. The room slowly goes silent, your fingers closing in around her as your orgasm approaches.

"Yes, I'm-" Hyojung’s cry dies away into gasping silence, the two of you cumming at the same time. Your hand tightens involuntarily around her neck, and you feel her pussy similarly clamp down on you, tight as a vise. She milks you for all you have and you willingly give it to her, flooding her insides with your thick cum, driving into her with every shot you release. You feel her arc her back and shudder violently against you, reveling in her own orgasm.

Rasping breaths and pants replace the loud screams that rang through the room previously when you finally come down from your high, your grip on her neck finally relaxing. You end up collapsing on her, pushing the both of you to the ground to recover. Making sure that you can't be seen through the booth window, you slowly get off her,  You quickly pull your pants up, slowly inching up to take a peek through the glass - luckily, it looks like whoever came in had left.

"It looks like we're clear."

"That's good. Oppa can you get me some wipes? They're in my bag." You look back down to see Hyojung sitting against the wall, a trail of white leaking out of her.

"Right, be right back!" You hurriedly grab her bag from the studio couch, digging around and eventually finding the wet wipes. You help her collect the vibrator and place everything back in place as she wipes herself of your combined juices. Hyojung looks delectable, adjusting her bra and buttoning up her blouse again, and you take the chance to plant a hickey on her pale collarbone, causing the girl to moan in delight.

"Hey! Now I'll have to hide it when we go on stage later today!" She pouts cutely at you.

"Sorry, I couldn't help myself."

"Thanks for playing along with me, that felt good." Her pout breaks into a beautiful smile.

"Of course, but we should be getting back shouldn't we, won't the other be done by now?" Hyojung checks her phone and yelps, beckoning you to follow her. The two of you exit the booth and carefully leave the studio, hoping that no one noticed your joint absence. The two of you are caught red-handed however, by none other than Mimi, the group's rapper leaning against the wall right by the door.

"Had fun?"

"Oh hi Mimi, what brings you here?"

"We finished, and it looks like the two of you finished too eh?"

"W-we... How did you know we were here?" Hyojung fires her an awkward smile, trying to pretend everything is normal.

"Unnie you're so silly, your bag was on the couch, and while the studio is soundproof, it certainly isn't smellproof! I could smell sex throughout the whole room!" Mimi smirks at her leader, enjoying the chance to make fun of her.

"Fine fine, please don't let the others know, I'll be teased forever!" Hyojung begs Mimi, trying to win her favor with cute puppy eyes.

"Why do they tease you?" You ask, but Mimi answers for her.

"We always joke that the reason she smiles all the time is because of all the cumming she's doing, unnie's insatiable, and looks like it's true."

"Please Mimi, don't let them know!"

"Fine, but I have a price."

"Yes! I'll buy you food, I'll do laundry for you!"
