Overview

Aya and Nanako met at a women-only SM club. Aya, a customer, likes Nanako, an masochist, and frequents the SM club. As they play more and more, they become attracted to each other and end up dating. She understands that Nanako plays with customers other than herself, but due to her loneliness, Nanako finds out that she also went to another SM club. S and M's positions are reversed, and Nanako humiliates Aya with the play that Aya was used to. Her situation gradually escalates and her body and mind are bound by Nanako.
