At the end of summer, when the cicadas began to sing quietly, a married woman, Keiko (Yuko Shiraki), and her friend Junko went to Sugiura's house, a psychological counselor, to hear about brain orgasms. Keiko, who felt unsatisfied with her unsatisfactory sex with her husband, decided to experience her brain. Keiko wets her crotch with her climax to Sugiura's caress that stimulates her five senses without touching her body. Keiko blushes and leaves the place, but she can't forget her pleasure, and she goes to Sugiura the next day.
