Koo woke up early, excitement buzzing through her veins like caffeine. She spent extra time in front of the mirror, making sure she looked like the perfect slut secretary. Today was her first “day of work” for Warden  Kim Taehyung, and she knew what he expected.

She slid into a tight red dress that clung to her body like a second skin, the neckline plunging so deep it barely covered her nipples. The hem was short enough that if she bent, her ass cheeks would spill out. No bra. A tiny black thong. Heels high enough to make her ass pop.

By the time she walked into the prison, heads were snapping, guards openly staring. She loved the way her heels clicked against the tiles, announcing her arrival like a queen entering her kingdom.

Koo pushed open the door to  Taehyung’s office. The old man was already at his desk, belly pressing against his uniform shirt, spectacles low on his nose as he pretended to read paperwork. But his eyes instantly locked on her, and his mouth curved into a wicked grin.

“Well, well, look at my brand-new assistant,”  Taehyung drawled. “Damn, sugar, you came dressed to ruin an old man’s self-control.”

Koo swayed her hips, smirking. “You said you wanted me to keep you happy, Warden. I’m just doing my job.”

He gestured to the desk. “Good girl. Start by sorting those files. Then we’ll see what else you’re good at.”

Koo leaned over the desk, intentionally giving him a perfect view down her neckline. Her tits hung heavy, nipples poking at the thin fabric, and she swore she heard him grunt. She wiggled her ass as she bent, pretending to organize papers.

“Mmm,”  Taehyung rumbled. “You’re makin’ it hard for me to focus, sugar. That ass… looks like two fat melons fightin’ to get out.”

Koo glanced back over her shoulder, biting her lip. “Maybe you should come help me… keep it in check.”

The warden stood, his chair groaning as his big frame shifted. He came up behind her, one hand sliding brazenly over her hip, the other palming her ass cheek. He squeezed hard, making her gasp.

“Damn, girl,” he growled, “soft as a pillow but built like a whore. You dress like this just to tempt me?”

Koo moaned softly. “Mhm… maybe I wanted to see if the Warden has strong hands.”

He chuckled low, voice full of filth. “Oh, they’re strong alright. Strong enough to keep a slut like you in line.” His palm slid up her side, rough fingers closing around one tit. He squeezed until she whined, then pinched her nipple through the thin dress.

“Fuck, that’s good,” Koo whispered, arching back into him.

“Sit down,” Taehyung ordered, dropping into his chair again. He patted his lap, his belly pressing against the desk. “Right here. Let’s see how well you can multitask.”

Koo turned, her cunt clenching with need, and slowly lowered herself into his lap. She felt his thick bulge pressing up under her ass, hot and heavy through his pants. She wriggled deliberately, grinding down.

“Good little slut,” he groaned, arms wrapping around her waist, hands sliding back to her tits. He kneaded them roughly, groaning in her ear. “These titties are gonna keep me alive longer than my blood pressure ever could.”

Koo giggled breathlessly, rolling her hips against him. “Mmhmm… guess I’m already doing a good job, huh?”

“Fuck yeah, sugar. You’re hired for life,” he grunted, squeezing both tits until she gasped. His mouth pressed to her ear. “Tell me—what do you think your boy would say if he saw you bouncin’ on an old man’s lap, lettin’ me squeeze the hell outta your fat tits?”

Koo moaned, pussy dripping onto her thong. “He’d… he’d probably kill you…” she panted, “…but right now, I don’t even care.”

“That’s my girl,” Taehyung growled, hand sliding lower, pawing at her ass. “You’re mine in this office. My personal slut. And every time you make me happy…” He gave her a particularly hard squeeze that made her squeal. “…your boy gets another favor.”

Koo tilted her head back, her lips parted, grinding shamelessly against the thick cock straining his pants. “Then I guess I better make you real happy, Warden.”

His laugh was dark, filthy, full of hunger. “Oh, sugar… you have no fuckin’ idea how happy you’re gonna make me.”
