Mei Kamisaka, after enduring repeated training, has transformed into a sex slave ● who becomes completely soaked at the mere sound of a man's voice. Her soft skin is tightly bound with rope, and overwhelmed by pleasure, she writhes in ecstasy, her face twisted into an ahegao expression. The man further torments her sensitive body, mercilessly assaulting her with lewd toys. Gradually, her body loses all resistance as she's handed over to a new group of perverted men, forced to climax countless times while being played with by complete strangers' dicks.
