Міюкі Мінегіші - секс красуні борделя ed. клас.

Grandma Miyuki has such a strong sexual appetite that she takes her grandson's clothes and masturbates with them while peeping on him while he is taking a bath. The reason why she is so active even though she has already reached menopause is that she used to be a prostitute. One day, when she learns that her grandson is a virgin who can't even go to the sex trade, she decides to help him overcome his phobia of women by taking the plunge. Grandma will teach him how to do it.
