The next morning, the doorbell rang just as Koo was finishing breakfast dishes.

She padded to the door, still in her tiny shorts and tank, and when she opened it—there stood Mimi.

Her best friend. Her partner in sin back in the day. Same slutty energy. Short dress, no bra, lip gloss shining.

“Mimi!” Koo smiled nervously, hugging her tight.

Mimi leaned close, whispered right into her ear, “Saw you yesterday.”

Koo froze. “W-what?”

Mimi smirked, pulling her phone out of her little purse. She tapped the screen and there it was—grainy video of Yoongi pounding Koo on the couch, her tits bouncing, moaning his name.

Koo’s stomach dropped. “Mimi—”

“Relax, slut,” Mimi purred. “I’m not ratting you out. But… introduce me to your new boys and I’ll delete this little treasure.”

Koo swallowed hard. “Mimi…”

“C’mon, Kookie,” Mimi smirked, brushing past her into the living room. “We both know you’re not selfish. Share.”

Koo’s chest tightened, but she had no choice.

Around noon, the door opened—the men had arrived for “renovation.” Taehyung came first, sweaty in his tank, Namjoon close behind, Yoongi lighting a cigarette as usual.

The moment they stepped inside, their eyes fell on Mimi.

She was perched on the couch, legs crossed, dress riding up her thighs. Her glossy lips curved into a knowing smile.

“Well, well,” Taehyung drawled, licking his bottom lip. “Koo didn’t tell us she had such a pretty friend.”

“Mm,” Namjoon’s gaze darkened, scanning Mimi up and down. “Very pretty.”

Yoongi smirked. “Looks like our slut keeps good company.”

Koo stiffened, heat rushing up her neck. That word—our slut. And now Mimi was sitting right there, soaking up their stares.

“Mimi,” Koo forced her fake smile, “these are… Taehyung, Namjoon, Yoongi. Our neighbors.”

Mimi stood, hips swaying, and shook each of their hands slowly, letting her fingers linger too long.

“Neighbors, huh?” she said, voice dripping with innuendo. “Lucky me. I live nearby, so I’ll probably be around a lot.”

Taehyung smirked, eyes flashing at Koo knowingly. “You should.”

Koo clenched her jaw, jealousy pricking like needles, though she didn’t show it.

For the rest of the afternoon, Mimi stayed glued to them—laughing at their jokes, leaning in too close, brushing her breasts against Namjoon’s arm “accidentally,” licking her straw in front of Yoongi while he stared straight at her mouth.

Koo watched every second, pretending not to care, but her stomach twisted. These men were hers. Her secret, her dirty escape. And now Mimi was shamelessly putting herself right in the middle of it.

At one point, Koo slipped into the kitchen for water, only to hear muffled voices drifting from the living room.

Yoongi’s low murmur. “You should come by our place tonight, Mimi.”

Mimi’s giggle. “Oh? All of you?”

Taehyung’s husky chuckle. “You can handle it, can’t you?”

Namjoon’s deep voice: “We’ll make sure you enjoy yourself.”

Koo’s grip tightened around the glass, her pussy clenching with equal parts anger and arousal.

Mimi was giggling again. “Maybe I’ll come… but only if Koo doesn’t mind.”

Koo stepped back into the room, pasting on her fake good-wife smile. All eyes turned to her, and Mimi’s grin widened like a cat who’d stolen the cream.

The men smirked knowingly, glances darting between the two women.

Koo sat down, legs crossed, acting calm. But inside, she was boiling—jealous, wet, guilty.

Because she knew tonight… her best friend might just become their next toy.
