Momoka, the innocent-looking Japanese coed, steps into the dimly lit karaoke room, her nose wrinkling at the unmistakable scent of spent semen. It's an enticing aroma, one that sets her heart racing and her pussy pulsating. She's been here before, but never alone, and never with the room still saturated with another's lust. She's drawn to the source, her fingers tracing the sticky spot on the couch, before she can't help but indulge in her own pleasure, fingering herself furiously to the silent, unseen melody of her own shameful desire.
