Two good friends, Sayuri and Non, are both mothers. One day, while the two were attending a meeting for mothers, the conversation turned to their sex lives. While her husband is busy with work, Sayuri seems to be enjoying a fulfilling sex life with a young guy she met on an app... Although I thought I didn't relate to this, I eventually gave in and opened the app with the thought 'Just this once...' The young guy she met is very obedient and awakened to the pleasures of domination. And the guy is also completely immersed both physically and mentally in the charms and tempting advances of a married woman.
