Good mom friends Ryo and Kaho. One day, when I was having a tea party as usual, the topic turned to sex life. Kaho seems to be having fulfilling SEX with a young boy she met on the app, and Ryo, who thought it was suspicious≪ starts the app as she is swept away by ≫ if it is only once. - Ryo, a student she met on the app, wakes up to the pleasure of dominating with obedience. - And Yuzuru is also drowning in her mind and body in the bewitching and sex appeal of a married woman.
