Aoi is a receptionist at a certain company. Tired from standing all day, she decides to get a massage recommended by her boyfriend. However, the masseuse turns out to be an erotic masseuse who performs obscene acts under the guise of treatment. After being violated during her first session, Aoi is threatened with photos of the act. The masseuse repeatedly calls her in and eventually shows up at her house. Before she knows it, Aoi's body has become so dependent on the services of this erotic masseuse that she can no longer live without them.
