Yuko (Mori Shimo), a married woman who works as a personal trainer, regularly invited her friend and her friend's daughter, Aya (Aki Shuri), to her home to teach them training. The time spent moving their bodies and sweating together was a pleasure for Yuuko, who was living a lonely life while her husband was on a long business trip. However, she did not know that Aya, who was much younger than her, was targeting her body. And that she would be overwhelmed by Aya's skillful lesbian technique, both physically and mentally.
