A young woman, lured into a dating app by her mother's friend, sweetly nurtures a "young man" she's dating. (Mary Tachibana, Yuna Mitsuki, JUR-177)

Mary and Yuna are best friends, both mothers. One day, at a casual tea party, the conversation turns to sex. Yuna seems to be having a satisfying sexual relationship with a young man she met through an app, and Mary, who initially found this suspicious, succumbs and starts using the app, thinking, "It's just something to try..." Mary's students on the app are very submissive, and she gets excited about the pleasure of domination. The young man becomes fascinated by the married woman's charm and her undeniable sex appeal.
