Busting

Hi oppa, can you come by the set?

Sure, be right there

You head over to Nayoung's set, finding it empty, the house they were using for the set barely lit.

I'm here, where are you?

Come by the front door

You push the gate open and walk up to the front door, giving it a soft knock. "Nayoung?" The door opens a smidge and you see Nayoung peek out.

"Oppa!"

"Why are you being so quiet—" Nayoung pulls you into the house before holding a finger to her lips, asking you to be quiet.

"Shhh!"

"What's going on?"

"I'm scared! I think there's a ghost."

"What? Don't be silly. There's no such thing."

"But! I heard weird noises, there was knocking upstairs too. I know for sure everyone went home after we finished filming!"

"Fine, let's go up and take a look then." You drag a reluctant Nayoung up the stairs, and you hear the knocking too, steady and persistent. As you get closer you realize the corporeal source of Nayoung's ethereal fears, the sound that floats down the hallway confirms it.

"Fuck, right there babe, right there!" A female voice moans passionately. Nayoung freezes behind you when she hears it too.

"It's not a ghost! Who is it?" The two of you sneak closer to the shut door, a bit of light spilling out from underneath it. As you continue to listen in on them, the pounding in your heart from nervousness gives way to arousal, thanks to pounding of a different kind.

"Do you know who it is?" Nayoung shakes her head, trying to lean in closer. The lovemaking couple helpfully answer the question for you.

"Fuck Hyewon, you're so tight!"

"Oppa I'm cumming, shit I'm cumming!" You hear a loud moan, and the knocking sound gets faster and faster, Hyewon's lover chasing his own orgasm. With a sudden groan you hear him finish, the knocking coming to a stop suddenly, replaced by harsh breaths and long moans of satisfaction.

"Hyewon? Kang Hyewon, your co-star?" you turn to ask Nayoung.

"I-I guess." Her face is red with embarrassment. "We should go before they notice us."

"No." You grab her by the wrist, pulling her past the door and into the adjacent room.

"What are you—" You hold a finger to her lips, shushing her.

"I want us to return the favor." The bed on the set is surprisingly soft as you tangle with Nayoung, both of you turned on by your earlier act of voyeurism.

"Are you sure we should do this?" she asks you, her face pink with arousal now, your hands sneaking under her shirt, dancing on her abs. Quite literally Nayoung warms up to your proposal, and you lean in to whisper in her ear.

"No, but we both want to. Imagine if they hear what we heard just now, hmm?"

Nayoung kisses you hungrily, tugging on your lip and your shirt. "That depends on how good a job oppa does then, no?" You give a hearty slap to her butt, making her yelp in surprise before she covers her mouth.

"How was that?"

"No fair! You know what I meant."

"I do, and I will," you growl, trying to pull her pants down and failing to do it in one shot. "Clothes off!" The two of you quickly lose your clothes, and the vision that is Nayoung's nubile body fills your view as she pushes you back on the bed before crawling up from the foot of the bed, eyeing your stiffness like a snack.

"Wait Nayoung!" you sit up and stop her. "Turn around." Nayoung catches your drift and spins around, presenting herself for you, lowering her hips over your face. "Let's—ahhh! Let's go!" Nayoung gets off to a headstart, your shaft bathed in her drool immediately. And with another moan into her dripping heat, you dive into Nayoung's delicious oyster.

Her moans reverberate around your cock, her tongue mimicking your actions. You tease her slit as she plays with your tip, and when you coax her open and spear deep into her, she moans and drops her head down your cock, dragging her tongue right down your shaft. It makes you groan, and the vibrations go straight through her body. Together the two of you cycle pleasure over and over, rolling your hips to prolong the act as much as possible, not letting the other get their way too easily.

"Ahh..." You get harder in Nayoung's mouth when you hear a whine come through the walls, the other couple deciding to keep going—did they hear you? If you could hear them, they could certainly hear you, but the rhetorical question blanks out in your mind as Nayoung goes particularly deep down your shaft. Her head bobs over your cock get faster and further—at this point you are moaning louder than she is, and that is unacceptable!

"Mmm fuggh!" Nayoung moans loudly over your throat as you plant a thumb on her clit, rubbing her firmly while your other hand goes to her back, keeping her tummy pinned on your chest. More importantly, it keeps her pussy fixed in range of your tongue, and you furiously eat her out, the volume of Nayoung's juice and cries increasing very quickly. You know you've won when you feel her warm mouth leave your cock, Nayoung throwing her head back and loudly moaning your name, her body trembling on top of you.

"God oppa!" Nayoung's orgasm hits her fast and hard, her tight body struggling to contain the explosion of pleasure traveling through her. Hyewon's moans through the wall mirror Nayoung's, her lover clearly trying to get her off as well. You slow down but never stop your licks, drinking from Nayoung until she relaxes on top of you. When she finally regains her strength she pushes off you and turns around, straddling your hips. She looked just as needy as before she came. "Ready?"

As your chin tilts down to nod, so does Nayoung's hips, sinking herself on your shaft, causing both of you to moan loudly, caution thrown to the wind as you hear Hyewon and her lover's cries grow in volume—no one gave a fuck about fucking anymore.

"That's it Nayoung, ride me!" you growl, watching her sexily bite her lip as she tries to maintain a little bit of dignity in front of her co-star through the wall. You pull her towards you, kissing her and allowing her to muffle her moans on your lips. Hips clash in rhythm with the knocks of the wall, and Nayoung begins to bring herself down on you faster and faster as Hyewon gets fucked harder and harder.

The clean set turns into a seedy love hotel, a cacophony of cries ringing around the room and through the thinnest wall ever built. The headboard in Hyewon's room drums rapidly against the thin wall as you thump your thick cock upwards into Nayoung. Desperately she moans into the kiss, her hands cupping your face and holding you close—it was almost intimate, except for a second couple banging right next door, their cries mixing with yours.

“Harder!” You’re not even sure who says it, the voices all sounding far away as blood pounds in your head, but you do as she says and plant your feet on the bed, pushing up into Nayoung even deeper. She has to bury her face in your neck to muffle her scream. The walls get ever thinner as the moans grow louder, and Nayoung’s walls get ever tighter as she gets wetter.

"I'm going to cum!" Nayoung whimpers frantically against you, trying to let you know. But you wanted to let them know—you thrust up harder into her, and Nayoung's eyes open wide, her typically stoic features contorting in pleasure just as she twists and contracts around you.

She mashes her lips on yours, but you have other ideas. You yank her hair not too gently, pulling her head away from you. Nayoung bites her lip, but she can't suppress her high-pitched whines any longer.

"Tell them." You make the bed creak, bucking furiously up into her.

"Fuck I'm cumming, oppa I'm cumming, fuck me fuck me fuck me!" With a loud lustful cry Nayoung loses it and bursts into pleasure on top of you, her body seizing up with electric bliss, muscles twitching and jerking out of control as she holds you close.

You roll her around, taking charge and fucking her through her orgasm. Her moans and little oversensitive whinnies serve to edge you closer to your peak—usually reserved, it turns you on that Nayoung is into this, into fucking on her set; it turns you on that she just screamed her orgasm to her co-star; it turns you on that her lithe figure, honed and toned through rigorous workouts, became boneless putty, her beautiful face similarly liquefied into erotically warped expressions of ecstasy; and given how wet she got, what turns you on the most is that she might be into this even more than you are!

"I'm so close, where do you want it?" You rut into her with deep thrusts, managing to draw her attention back from her orgasm just long enough for her to speak.

"Don't, ah! Don't make a mess!" Her mouth drops open, and in a flash you pull out, moving up and pushing your cock past her lips before finishing the job the 69 earlier couldn't. A few quick pumps into her face all that is needed. You slam the wall for effect as you start unloading down Nayoung's throat. She chokes a little, but her throat and tongue milk you for all that you have, and the loud moans that reach their crescendo in the neighboring room eke out just that little bit more cum from you as well.

Your own orgasm lasts longer than expected, and you pull out early, causing the last few drops of seed to trickle down her neck and chest, mixing with her sweat—it made Nayoung look even more wanton. She simply lays back and smiles as you fall back opposite her, her fingers absentmindedly spreading your cum over her flawless skin, looking utterly satisfied.

Reality sets in soon after, and hurriedly Nayoung grabs some tissues from her purse to wipe herself, her face red from embarrassment again. She turns redder when she sees the absolute mess she made on the sheets, a large wet spot very visible from when she came.

"Oh no, what do we do!"

"Just leave it. When does your filming start again, it'll hopefully dry off by then?"
