47-year-old housewife Hitomi has been struggling with boredom throughout her long marriage. One day, she spots a magazine ad offering training and support to open her own massage business. Intrigued by the prospect of making money while filling her time, she's especially drawn to the perk of being able to freely touch men's bodies under the guise of treatment. With her sex life long dried up and desire building, Hitomi decides to take on a new challenge—seduce her instructor first.
