It was a Saturday evening when Koo came over again, as usual, in a skin-tight little black dress that looked more like lingerie than something to casually wear to a friend’s house. Mimi didn’t question it; she was used to Koo dressing like a slut. The two of them sprawled out in the living room, laughing about a guy Mimi had hooked up with last week.

But then the front door opened.

Koo’s head snapped up, her heart skipping when she saw Taehyung step in. He looked devastating as always—tall, broad, wearing a navy suit that hugged his body perfectly. But what made Koo’s smile falter, what made her stomach drop, was the woman on his arm.

She was around Taehyung’s age. Beautiful, elegant, in a long silk dress with diamonds glittering on her wrist. Taehyung’s hand rested on her lower back as he guided her inside.

“Girls,” Taehyung greeted, his deep voice calm, “this is Hana, a friend of mine.”

Koo’s throat tightened. Friend. Right. The way Hana leaned into him, the way his hand lingered on her waist—it was clear this was no casual friend.

Mimi perked up, giving her father a playful grin. “Hi, Hana,” she said sweetly, then glanced at Koo. “Dad, you didn’t tell me you were bringing someone over.”

Koo forced a smile, but inside, rage boiled. Her nails dug into her palms under the table. She had dressed for him. She had been waiting for him to notice her. And instead, he walked in with some woman who clearly already had his attention.

Her chest felt tight, her eyes burning. Before anyone could notice, Koo mumbled something about needing to leave early. Mimi blinked in surprise. “Already? Babe, we were—”

“I just remembered something, sorry,” Koo cut her off, already grabbing her purse. She didn’t even dare glance back at Taehyung as she rushed out the door, her heels clicking against the marble floor.

By the time she got home, her whole body was shaking. Jealousy, sadness, lust—they tangled inside her like a knot. She slammed the door shut, her eyes stinging with tears.

“Fuck,” she gasped, kicking off her heels. Her chest heaved, nipples straining against her dress. She couldn’t get the image out of her head—Taehyung’s hand on that woman, Taehyung smiling at her, Taehyung bringing her home.

“No… no, he’s mine,” Koo whispered, her voice breaking. “He’s supposed to be mine.”

She yanked the dress off, tossing it aside, standing in nothing but a lacy thong already soaked through. She stumbled to her drawer, pulled out her thick pink dildo—the one she always used when she thought about him. Her hands shook as she dropped onto the bed, spreading her legs wide, tears streaming down her flushed cheeks.

“Taehyung…” she whimpered, pressing the toy against her swollen pussy. Her folds parted easily, wet and needy. She shoved it inside, crying out as her back arched. “Ahh—fuck, Tae—!”

Her tears blurred her vision, but she didn’t stop. She thrust the dildo harder, faster, her thighs trembling. “You’re mine, you’re mine,” she sobbed, moaning his name. “I’ll make you see me, Tae, I’ll make you want me—ahhh, god—”

The thought of him with that woman made her insane, but it also fueled her lust. She imagined ripping Hana away from him, imagined dropping to her knees in front of him, sucking his cock until he forgot every other woman existed.

“Fuck me, Tae, please,” she cried, pounding the toy into her dripping cunt, the wet sounds echoing in her bedroom. “Your slut, your baby girl—nnghh—”

Her other hand clawed at her tits, squeezing hard, pinching her nipples until she screamed. Her thighs shook violently as the orgasm ripped through her, her pussy clenching around the dildo.

She collapsed back on the bed, sweaty, crying, her voice hoarse from moaning his name.

“You’ll be mine,” she whispered to the empty room, her chest heaving. “I don’t care who else you bring home. You’ll be mine, Taehyung. I’ll make sure of it.”

And with that promise burning in her veins, Koo drifted into a restless sleep, still clutching the toy sticky with her arousal.
