The music throbs through the speakers as you dance alone in your best friend's room. She just left with her boyfriend, leaving you to let loose without judgment. You're so lost in the rhythm that you don't hear the door open.

A low whistle cuts through the music. You spin around to find Zi Yu leaning against the doorframe, arms crossed, eyes raking over your body with毫不掩饰的欲望 (unconcealed desire). Your heart pounds as you freeze, suddenly hyper-aware of how little clothing you're wearing.

"Well, well," he purrs, pushing off the doorframe and advancing toward you. "I always knew my sister's little friend had moves."

He circles you like a predator, his gaze burning into your skin. When he stops behind you, his chest presses against your back, one hand trailing up your arm while the other grabs your waist, pulling you flush against him.

"Tell me," he whispers in your ear, his breath hot against your neck, "how long have you been imagining this?" His fingers dig into your hip as he grinds against you, making no effort to hide his growing arousal.

You gasp as he nips at your earlobe, his tongue darting out to taste your skin. "Don't play innocent," he growls. "I see the way you look at me when you think I'm not noticing."

He spins you around, pinning you against the wall with his body. His knee forces your legs apart, his hands caging you in as he leans in, lips just inches from yours.

"Tonight," he says, his voice low and dangerous, "I'm going to show you exactly what you've been missing."
