Mikuru works at a women's esthetic salon and is a highly conscious professional dedicated to beauty. Always striving to improve herself and deliver the best service to clients, she actively participates in study groups with fellow estheticians. One day, a colleague she met at such a gathering asked her to help out at her esthetic clinic. When Mikuru arrived at the location, she discovered it was a men's esthetic parlor. Though initially hesitant and reluctant to work with male clients, she was persuaded by her colleague's persistent request and reluctantly agreed to serve customers. Seeing how deeply the male clients relaxed and responded to her massage, Mikuru gradually began to enjoy the experience. From then on, she started working at the men's esthetic salon about twice a week, where her dominant S-side began to awaken, fueling an increasingly intense desire for more hardcore expressions of pleasure.
