Dragged into a secret underground facility in Tokyo, modern high school girl Mirai Natsume finds herself at the mercy of her captors. Her defiant, arrogant expression demands immediate correction through hard slaps and choking, forcing her into submission. Restrained with iron shackles, her naked body is exposed in humiliating positions as her anus is assaulted by the officer's massive cock, brutal sex toys, and the infamous medieval European torture device known as the Pear of Anguish. As pain transforms into pleasure, a new anal slave is born. #YuhiP
