That night, long after her husband had fallen asleep with a smile on his face, Koo lay wide awake in bed, staring at her phone.

A new message blinked across the screen.

Tae: So… how did your husband like his little promotion?

Her cheeks burned. She typed quickly, her fingers shaking.

Koo: He’s so happy… thank you…

A smirking emoji popped up almost instantly.

Tae: Don’t thank me, slut. You earned it. Remember the way you begged for my cum? That’s what bought his future.

Koo swallowed hard, her pussy throbbing under the blanket. She turned to check on her husband — he was snoring softly, blissfully unaware. Clutching the phone to her chest, she bit her lip, shame and heat twisting inside her.

The next morning, her husband kissed her sweetly before leaving for work, humming happily, still glowing from his success. “I’ll make you proud, baby. Tonight, let’s celebrate properly, hmm?”

Koo smiled and waved, but the moment the door shut, her phone buzzed again.

Tae: Come to me.

Her heart raced. She typed, her hands trembling.

Koo: No… I can’t… I shouldn’t. Yesterday was a mistake. I’m married…

She set the phone down, pacing the living room, squeezing her thighs together as her pussy clenched just at the memory of him. No. I can’t. I won’t.

An hour passed. She was breathing easier, convinced she had resisted… until her phone vibrated again.

A video file.

Hands shaking, she tapped it open — and froze.

It was them. Her and Tae. The couch, her straddling his lap, her tits bouncing in his face, her voice crying out shamelessly: “Fuck me, Mr. Kim! I’m your slut! Use me!”

Her gasp broke the silence. She dropped the phone to the couch, covering her mouth, tears welling in her eyes. There was a camera? He recorded it?

Another message arrived.

Tae: You looked so good moaning like that, baby. Better hurry to me… before I show this to your husband. Or the whole world.

Her knees gave way, and she sat down hard, thighs squeezing, pussy clenching so tight it hurt. The shame, the fear, the rush of knowing she had no choice—it all made her wetter than she wanted to admit.

She typed with trembling hands:

Koo: Please… don’t…

Another reply snapped back.

Tae: Then come. Be my whore again.

Her hand slid down between her legs almost without thinking, pressing against her soaked panties. She moaned softly, shaking her head at herself. Why am I like this? Why does this turn me on?

Finally, defeated, she whispered to the empty room: “I’ll go…” and typed back:

Koo: Okay. I’ll come.

A final message appeared instantly:

Tae: Good girl. Be here in an hour. And wear something slutty.

Koo dropped the phone onto the couch, burying her face in her hands. Her pussy throbbed with need, already leaking through the thin fabric of her panties. She hated herself… but she was already thinking about what to wear for him.
