Yuri Toka uses a finger brush to meticulously tickle an M man whose hands and feet are securely bound with restraints. Her hidden sadistic side is unleashed, clearly enjoying herself to the fullest. Gentle, careful tickling makes his penis hard, while he writhes under a stream of dirty talk. Yuri's increasingly excited demeanor is adorable and intensely erotic—her relentless teasing continues even as he cries out, "Ah! That spot's sensitive!" Her irresistible aggression makes this a must-watch M man release, highly recommended.
