Kanna, who works as an erotic novelist while hiding from her husband, and her mom friend, Yuri. One day, when she was having her usual tea party, the topic turned to sex. Yuri seems to be having a fulfilling sex life with a girl she met on an app, and even though she's shy, she semi-forcibly recommends the app to Kanna to find material for her novel... Taichi, a student I met through the app I started, is obedient and honest.
