Kana and Hana are good friends who are moms. One day, while the two of them were having a moms' get-together, the topic turned to sex life. Hana seems to be enjoying a fulfilling sex life with a young man she met on an app while her husband was away at work, busy with work... Kana, who thought she had nothing to do with it, also started using the app, swaying her to start using it "just once..." The young man she met is obedient to Kana, and she awakens to the pleasure of dominating him. And the young man is also drowning in both mind and body in the married woman's seductiveness and the way she attacks him with her full sexual appeal.
