Kana and Hikaru are close mommy friends. One day, while having their usual tea party, the conversation turns to sex. Hikaru seems to be having fulfilling sex with a young man she met on an app, and even Kana, who had thought it was a bit shady, ends up starting the app herself, thinking, "Just once won't hurt." The student she meets on the app is obedient, and Kana awakens to the pleasure of domination. Meanwhile, the young man is also captivated by the alluring charm and full-on seduction of the married woman, both mentally and physically.
