A story of two pairs of mother and child. Tatsuo Takayama, a boy who goes to a university in Tokyo and lives alone. Due to the renovation of the house, my cousin Yoshio Akiyoshi and my aunt Taeko Akiyoshi are the homes of my mother Kayoko Takayama. In other words, he lives in Tatsuo's parents' house. One day, Tatsuo returned home as originally planned, but he could not forbid sexual excitement for his mother, and after an obscene delusion, he repeatedly sexually acted and even vaginal cum shot. At the same time, Yoshio spends his days in agony with his mother, Taeko Akiyoshi's beautiful ass. And I also witness the mother and child incest of the Takayama family.
