Happy Birthday (ft. LOONA's Heejin & Chuu)

“What colour are we?”

“Gr—Green, unnie!”

“Good.”

The tip of Jiwoo’s cock teases the entrance of Heejin’s ass. Heejin whimpers at Jiwoo’s touch, her hand on the underside of one of Heejin’s thighs, the other on her huge shaft, guiding it inch by inch into Heejin’s asshole. Heejin’s cock twitches when Jiwoo bottoms out, a low growl emitting from within her chest.

“God, this never gets old.” Jiwoo smiles, beginning to pull herself out of the tight grip of Heejin’s ass. Even with all the preparation and lubrication, Heejin still is so sinfully tight. A snap of Jiwoo’s hips sends her full length back into Heejin, and Heejin has to choke back a loud groan as Jiwoo’s huge cock hits her square in the prostate.

“Go on, Heejinnie. Moan for unnie. You know you want to.” A withdrawal.

Another snap.

“Ugh~!” Heejin’s broken moan is loud. She dimly wonders if anyone outside can hear Jiwoo having sex with her. After all, it’s not like they’re in the dorm, or in a hotel room, or somewhere particularly private.

Today, Jiwoo ambushes Heejin in the company vocal practice room. It doesn’t take long for them to delve into innocent kisses from normal conversation, then for the innocent kisses to turn heated, and soon enough, clothes are being torn off bodies. Right now, Jiwoo is naked, her hair untied. Heejin has a hoodie on, but her hair is in a ponytail. The hoodie is all she wears—she is just as exposed as her Jiwoo-unnie is. Heejin stares nervously at the glass door to her vocal practice room, her cock twitching at the thought of being discovered.

“Oh, Heejinnie. Look at you, twitching and dripping at the thought of being seen. What a naughty girl you are, mm?”

Jiwoo forces her legs open, beginning to speed up her thrusts. Her hips clap against Heejin’s ass, sending ripples along her skin when she bottoms out in her asshole. Every thrust sends Heejin’s tiny cock bouncing, ripping moans out of her throat when Jiwoo’s cock stretches her that good, hitting her prostate with every stroke.

“Hehe, you’re so cute, Heejin. Look at your tiny cock, that pathetic thing flopping about as you take your unnie up your ass. I can’t believe people think you’re part of the dom line. How can you be a dom when you’ve got such a pathetic tiny dick?”

Heejin’s precum spills all over her tummy at her Jiwoo-unnie’s words. Jiwoo-unnie is huge—her cock stands straight and proud, large veins running all over it. Heejin sometimes compares it to be similar to the size to a canned drink. However, as compared to her unnie, or to the other members, Heejin has the smallest dick. She barely fits in her own palm, whereas she knows Jiwoo, Sooyoung, and Hyunjin all need more than that from her. While she is secure in her own length, the degrading of her size compared to her unnies will always get to her in the best way possible.

“God, your ass is so fucking tight, shit…” Jiwoo reaches up to her own breast, roughly grabbing it and pinching her own nipples. “Touch yourself, Heejinnie. Jerk that tiny cock for unnie.”

Heejin whimpers, reaching to pump herself at the speed Jiwoo pumps her with. Jiwoo laughs when Heejin’s tip barely reaches past her own hand, unfiltered whimpers and groans mixing with the sounds of sex.

“Oh my God, Heejin. How does it feel knowing you’ll never get to fuck any of us like we fuck you? Look at you—small, tiny, useless. Even Yeojin gives better dick than you, because unlike you, she actually can.”

Heejin whimpers at the comparison to their maknae. Jiwoo’s dirty talk and degradation never fails to rile her up.

Jiwoo’s dirty talk is broken up with heavy pants and the wet claps of her sweaty hips meeting Heejin’s sweaty asscheeks. Heejin watches as a droplet of sweat runs down Chuu’s neck, down to her collarbones, then between her breasts. It carries on over her flexing abs, then dripping off to somewhere she can’t see. Heejin regularly checks the empty corridor, worried about being caught.

“Keep your fucking eyes on me, bitch.” Jiwoo grabs Heejin’s chin, gripping her to meet in intense eye contact. “Colour?”

“Green, unnie!”

“Good. Keep your fucking eyes on me. I don’t care even if the CEO’s watching. I’m going to fuck the cum out of you, Heejin, and I’m going to make sure I fuck your ass full of mine too. Is that clear?”

“Oh, FUCK!”

Heejin explodes once she processes her unnie’s words. Jiwoo’s relentless strikes on her prostate and her own jerking of her own cock is more than enough to get her close, but once Jiwoo promises to fuck the cum out of her, she gets roundhouse-kicked off the edge of the cliff into her orgasm.

Heejin cries wantonly in pleasure, her semen firing up all over her breasts, her chin, across her own flexing abs. Not a single spot of her torso is spotless—she covers herself in her own semen. White, sticky, thick cum paints her large chest, strings of it connected over her abs back to her twitching shaft. Jiwoo’s eyes burn with lust, watching Heejin orgasm turns on something even more primal in her.

Abruptly, Jiwoo pulls out harshly. She pulls Heejin to stand, ripping her sweat-soaked hoodie off her. She pushes Heejin roughly onto the table, front side down, spreading the cum on Heejin all over the surface of the table. With one deep thrust, Jiwoo hits the hilt of her shaft in Heejin’s gaped asshole, fucking deeply into her.

“Colour?”

“Green! Green! Yes, fuck me, please, please fuck me more, fuck me full, unnie!”

“That’s what I like to hear, Heejin. I won’t be done with you until I make sure you empty your balls all over this floor, and I empty my cum into and onto my favourite cumdump.”

Heejin’s wanton moans and Jiwoo’s deep grunts, mixed with the relentless claps of sex are the only sounds audible in the room. Heejin is sure that the sex she has with her Jiwoo-unnie is audible even in the hallway, maybe even at the two ends of the hallway, or the lobby. Heejin’s body rocks with each thrust, her breasts jiggling with every clap of Jiwoo’s hips against her ass. Her head is roughly pulled back, a hand wrapped around the base of her ponytail. Heejin lets her jaw hang loose, drool beginning to leak down her chin as she groans repeatedly, feeling her second orgasm slowly approaching. She gasps when Jiwoo grips her cock hard, jerking her hard as she strikes her prostate again and again, just as relentlessly as the first time.

“Spill.”

Heejin screams, her ass tightening and her hips bucking wildly. Another deluge of thick, creamy semen shoots out of her, all over her own feet, the floor, on Jiwoo’s hand. Heejin barely manages to count about 8 shots of semen, similar to her first orgasm. It splatters on the wall, the floor, her feet. Heejin makes a mess of her vocal practice room.

Behind her, Jiwoo contributes to the mess. Heejin’s ass tightening painfully around her shaft is all she needs to finally let go. Jiwoo groans as she lets the first two thick spurts of cum fire deep into Heejin, painting her insides white. In between the first two and the next shot, she pulls out, using Heejin’s cum as extra lubricant to stroke her own shaft. The next four shots of semen fire all over Heejin’s ass and back, making a mess of her body and the desk beneath her. Jiwoo’s final two shots fire weakly on Heejin’s calves as her knees buckle, barely holding on to the table for support. Jiwoo nearly topples over, catching herself over the back wall as she gazes upon the mess of cum, sweat, and other fluids within the room.

A loud splatter of something hitting the glass startles both girls. They stare out of the room only to see Hyeju, their second youngest, mid-orgasm. Hyeju’s hand is wrapped around her own thick shaft, her cum splashing down the glass of the door as leans on the door, her arm on the glass for support. Her hot breath fogs up the glass, her hand furiously jerking her cock to finish off her own peak.

When all three girls meet eyes, Hyeju shyly steps into the room, her cock still standing proud after her orgasm. Similarly, both Jiwoo’s and Heejin’s cocks stand hard. Hyeju’s display is more than enough to arouse the both of them.

“Let’s go home, unnies. I want in on your birthday sex.”
