Chiharu Koharu (23) and Yoshiki (28), a loving couple, embark on a project to test the strength of their true love. However, hidden beneath this plan lies a crazy objective: "making her debut in female-oriented adult services right in front of her boyfriend!" While her boyfriend is lured into a dreamlike state, a highly skilled therapist known for her techniques that completely shatter rational thought makes her appearance. Using her vast experience and expertise, the therapist gradually overwhelms Chiharu, driving her into a trance-like state where she trembles in ecstasy, climaxing repeatedly with her petite frame. Then, in the midst of it all, comes an unexpected twist—the therapist turns the tables and begins seducing the boyfriend instead!
