The woman's body, completely immobilized by ropes and iron, is crawled over by men's desires. Her exposed breasts and genitals are slowly savored by fingers and tongues. She is trapped in relentless teasing, with no escape from the pleasure. Driven by her body, which has become a mass of unfulfilled desires, she forgets that she is a sexual object and pleads for penetration. Minami Hatsukawa's hardest, endless pleasure prison of restraint. Enjoy the never-before-seen expression of her collapsing in humiliation and shame.
