Mami Miyagi is a sexually frustrated married woman who has only ever had conventional sex with her husband and is dissatisfied with their love life. Wrapped in a kimono, she looks especially elegant and untouched, yet she has endured a year without marital sex and masturbates about three times a week. Her kimono is removed, her hands and feet are restrained, and her most sensitive spots are relentlessly teased until she writhes through repeated orgasms. Pleasure she has never experienced with her husband makes her whole body tremble as the desire hidden beneath her happy marriage finally explodes.
