The male's sexual desire crawls around the woman's body, completely secured with rope and iron. Her exposed breasts and genitals are slowly chewed by fingers and tongues. There is no escape from the endless teasing of pleasure. Driven by a body that has become a mass of frustration, she forgets that she is a sex tool and begs to be taken in. Minami Hatsukawa's hardest, never-ending prison of pleasure. Enjoy the expression you have never seen before, with her face distorted with humiliation and shame.
