Saori Asada works at a karaoke box and one day catches the attention of a male customer. Using a special device capable of manipulating time and people's minds, he takes control of her consciousness. Left alone together in a private room, he demands she undress, and she obediently strips completely naked. Instead of a microphone, a vibrator is pressed against her crotch, its sounds amplified through the mic as she becomes absorbed in masturbating while listening to her own voice. Watching her closely, the man grows eager to penetrate her and thrusts into her repeatedly from behind and in missionary position, making her convulse and climax over and over. Her mind now fully under his control, her body moves exactly as he desires.
