A story about two mothers and children. Tatsuo Seino, a son who goes to a university in Tokyo and lives alone. Due to the renovation of the house, my cousin Masaru Fubuki and my aunt Harumi Fubuki are living with my mother, Fumie Seino. In other words, he lives in Tatsuo's parents' house. One day, Tatsuo returned home as originally planned, but he couldn't help but be sexually excited about his mother, and at the end of obscene delusions, he had sex many times and made a lot of vaginal cum shot. At the same time, Masaru recognizes his own mother, Fubuki Harumi, as a woman and spends his days in conflict.
