Yayoi cannot feel pleasure during sex with the boyfriend she loves, and his growing frustration leaves her desperate. She finds an online sensual spa specializing in submissive treatment for women with low sensitivity and decides to seek help. Nipple teasing, choking, forced deep-throat and deep cervical stimulation gradually awaken her body. The treatment works so thoroughly that she eventually orgasms even as the therapist pins her in a breeding press and creampies her hairless pussy.
