Yuko (Morishita Mio), a married woman who works as a personal trainer, regularly invites her friend and her friend's daughter Aya (Atomi Shuri) to her house to teach her how to train. The time when three women move their bodies and sweat was a fun time for Yuko, who lives a lonely life while her husband is on a long business trip. However, I didn't know at the time that Aya, who was one or two years older than me, was aiming at Yuko's body. And she finds herself immersed in Aya's skillful lesbian technique.
