Hibiki Otsuki and Meguri (Megu Fujiura), good friends and fellow mothers. One day, while having their usual tea meeting, the topic shifts to their sex lives. Hibiki, who seems to be having fulfilling sex with younger men she met on an app, is initially wary, but Meguri, after being swayed by "Just trying it", starts using the app... The student she met on the app is submissive, and Meguri awakens to the pleasure of dominating. And the younger man is also drowning in the number of Meguri's seductive and sexually charged attacks as a married woman.
