Koo was the kind of woman who made heads turn no matter where she went. Her snow–white skin seemed to glow even in dim light, her pink pillowy lips always parted in a teasing smile, and her body—those enormous boobs barely restrained by her tiny tops, her wide, juicy ass poured into micro–shorts or slutty dresses—looked built to tempt. And she liked it that way. She loved slutty clothes, low-cut, tight, short, always showing off, even if her husband Chen blushed at the attention she attracted.

Chen loved her deeply. He was the kindest man she had ever known—gentle, loyal, never raising his voice. But he was naive, almost too good. And in bed? A disappointment. He tried, he really did, but his small cock and soft rhythm left her staring at the ceiling night after night. Koo faked her moans because she didn’t want to hurt him. She loved him as a husband, but her body craved something else, something rougher, harder, filthier.

On Chen’s birthday, she threw a big party in their house. Neighbors, friends, family—everyone was invited. She dressed herself in a tiny black dress that barely covered her thighs, the neckline plunging low enough to show her soft cleavage that bounced with every step. The way some of the men looked at her told her they could see her nipples pressing against the thin fabric. Chen just smiled proudly, as if having such a gorgeous wife on his arm was enough to make up for everything else.

The party buzzed downstairs—music, laughter, drinks flowing. Koo slipped away upstairs to fix her lipstick and use the washroom. She pushed the door open to one of the guest bedrooms and froze.

There, standing by the bed, was their neighbor Taehyung. Tall, broad, older, with muscles that strained his shirt—though right now his pants were shoved down to his thighs. His hand was wrapped around his cock.

And God… it was huge. Thick, veiny, long, heavy, drooling precum as he stroked himself.

Koo’s lips parted. A soft, involuntary moan almost escaped her throat.

Tae’s sharp green eyes flicked to her, catching her gaze, and his mouth curved into a smirk. “Caught me,” he drawled, not looking embarrassed in the slightest. Instead, he stroked himself even slower, deliberately showing off. “Like what you see, sweetheart?”

Her thighs squeezed together, the slutty little dress riding higher. She didn’t answer, but her body betrayed her—her breath hitched, her lips trembled.

“Close the door,” Tae said, voice low and commanding. “Then get on your knees. Suck me off like a good girl.”

Koo knew she should run. Knew Chen was just downstairs, laughing with his friends, trusting her. But her pussy clenched at Tae’s tone, her heart raced, and before she realized it, she obeyed. She closed the door softly, dropped to her knees on the carpet, and crawled toward him.

Tae towered over her, cock thick and heavy right in front of her face. She looked up at him through her lashes, lips parted, then leaned forward and pressed a wet kiss against the swollen head.

“Mmm, fuck,” Tae groaned, gripping her hair. “Knew you were a little slut the second I saw you.”

Her tongue flicked out, swirling around his tip, tasting his salt. Then she opened wide and slid him into her mouth, stretching her lips around his girth. He was so much bigger than Chen—so thick she gagged on the first push, but Tae just chuckled and pushed her deeper.

“That’s it,” he grunted, forcing her to take more. “Choke on it, baby. Show me how bad you’ve been starving.”

Tears pricked her eyes, spit spilling down her chin as her throat tightened around him, but her pussy throbbed with need. Her hands gripped his thighs, bobbing her head faster, drool dripping onto her cleavage as she worked him. The sounds were obscene—wet slurps, muffled gags, his deep groans filling the room.

Downstairs, the party roared on, completely unaware.

Up here, Koo was on her knees, dressed like a whore, sucking her neighbor’s cock like her life depended on it. Tae tugged her hair back, making her look up at him with his shaft still stretching her lips.

“You love it, don’t you?” he sneered. “Your pussy’s soaked under that tiny dress right now, I bet.”

Koo moaned around his cock, nodding desperately. She wanted to touch herself, to grind against the floor, but he had both her hands pinned by his thighs.

“Good girl,” Tae growled. “You’re mine now.”

And Koo knew, with every filthy suck, that this was the beginning of something she wouldn’t be able to stop.
