Yuka cannot stop thinking about the woman's moans she hears next door almost every day. When she learns that her neighbor Tabuchi is a bodywork therapist, her husband encourages her to book a session. Tabuchi gropes her entire body and relentlessly massages her pussy, making her more sensitive by the minute. Unable to forget the pleasure, Yuka accepts another invitation from him. The thrill of being humiliated all over gradually breaks down her resistance and conditions her into an obedient bitch who submits to pleasure.
