Sayuri and Non are good friends who are moms. One day, while they are having a moms' get-together, the topic turns to sex life. Sayuri seems to be enjoying a fulfilling sex life with a young man she met on an app while her husband is away at work, busy with work... Non thought she had nothing to do with it, but she gets carried away and starts using the app, thinking "it'll be just once." The young man she meets is obedient and awakens to the pleasure of dominating. And the young man is also drowning in mind and body in the married woman's seductive and sexy attacks.
