I was loved by younger lesbians

Yuko (Morishita Mio), a married woman who works as a personal trainer, regularly invites her friend and her daughter, Aya (Atomi Shuri), to her home to teach them how to train. The time for the three women to move their bodies and sweat was a fun time for Yuko, who is living a lonely life while her husband is on a long business trip. However, I didn't know at the time that Aya, who was a little older than her age, was aiming for Yuko's body. And I think that Aya's skillful lesbian techniques will drown both her body and mind.
