The hot spring inn where Rina serves as the landlady is her mother's family home. Since there was no successor, Rina has been running the place for the past 20 years. Naturally lustful, Rina would relieve stress from her work through masturbation. One day, a former student from when she was a preschool teacher visited her saying, 'I have something I want to consult about.' The consultation was that he 'couldn't confess to the woman he liked.' On top of that, this former student was still a virgin. Seizing the opportunity, Rina decided to take off her clothes for the sake of the virgin.
