In the sterile room, various iron restraints are placed… eight women fixed in place. No matter how delicate and beautiful a woman may be, once she enters here, it's all over. She becomes nothing more than an anal toy in this terrifying place. Whether she cries or screams, the iron restraints dig into her soft skin, making escape impossible. Her exposed anus is savagely violated by mysterious men. Even the wrinkles of her anus are carefully admired, and when her trembling anus is penetrated with a huge cock, various foreign objects, or even the torture device called 'Pear of Anguish,' her masochistic nature awakens, and pain gradually transforms into pleasure.
