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, thinking "It'll be just once." Kana is obedient to the young man she meets, and awakens to the pleasure of dominating him. And the young man is also drowning in both Kokoro and body in the married woman's seductive and sexy attacks.
