Kaori, a therapist at a certain high-class men's esthetic salon, excels in customer service, treatment, and appearance. However, she uses her charm to seduce clients she likes, saying, "Make me feel good too!" Her request is to be hurt, a masochistic plea. Despite her pure appearance, she has a dominant masochistic fetish. Men respond vigorously with spanking and irumachio. With toys, restraints, and anything goes, Kaori, transformed into a beast, reaches ecstasy with a blissful expression each time she is punished.
