This 30-year-old married woman is in her second year of marriage to a 42-year-old supervisor from the same workplace. She loves her husband but hides an intensely kinky side: 15 previous partners, sex once every two weeks, daily masturbation and constant frustration. She is summoned to a building in the heart of the city, only minutes from one of Tokyo's largest stations. After having a remote vibrator inserted for the first time, she nervously steps onto the public street. A sudden jolt shoots through her crotch, leaving her unable to stand as breathy moans escape. It is her first experience trembling under remote control, and although the public humiliation is overwhelming, the pleasure feels far too good.
