This is the first bondage work in which the busty, glamorous Akari Nanahara's body is thoroughly tied up and trained! A secret auction club where only the most perverted sadists gather. The woman put up for auction this time is a female teacher who was raped by a student and sold by the student's father... She is tied up to a hanging pole and subjected to sadistic torture! She is restrained by an iron pipe and subjected to repeated forced creampie sex! She is tied up to a guillotine and hung by one leg and subjected to toy torture! She is tied up as a bondage slave and impregnated in a gangbang foursome... Her body is tightly bound and defenseless, and she is violated, becoming a creampie urinal!
