This production features two masochistic women, and one of the attractions is the amateur bodies that are so erotic. The first woman is a 19-year-old university student with G-cup breasts. She was awakened to her masochistic nature through perverted play with an older man, and she still enjoys masturbating every day. The second woman is a 24-year-old English conversation school instructor whose masochistic nature blossomed through hardcore sex and perverted play with a foreign colleague. Recently, she has also had a relationship with one of her students and has been trained, but she felt it had become monotonous, so she applied for this production. Both women were excited during filming and climaxed multiple times, transforming into sex slaves. The changes they undergo are the highlights of this video.
