Close mom friends Mifune and Yoha. One day, while having their usual tea party, the conversation turns to sex life. Yoha seems to be having fulfilling SEX with a young man she met on an app, and Mifune, who had thought it was something shady, finds herself agreeing to ≪just once≫ and ends up starting the app… The student Kyoken that Mifune meets on the app is obedient, and she awakens to the pleasure of dominance. And Kyoken too becomes engrossed in both mind and body by the allure and full-on assault of a married woman’s seductiveness―.
