I have returned to my parents' house where my brother and his wife live. Soon after, it was decided that his older brother would be transferred on his own. And his neat and cute wife Hibari is all alone. One day, Hibari-san came to my room and asked. My brother and I have exactly the same sexual tendencies, and for some reason he seemed to know the contents of the slut videos we were watching together... When I woke up, a sexy-looking Hibari-san was standing in front of me. With her brother's guidance, Hibari seemed to have awakened to being a fine slut. From that day on, in order to relieve my loneliness, Hibari started having sex with a lewd woman, blaming me all the time.
