It is a story of mother and child. In order to rebuild the family, his son Yoshio AKIYOSHI and his mother Eko AKIYOSHI resided in the family of their aunt Kozan-yoshi. He rents a room for his cousin Tatsuo Takayama, who lives alone at a university in Tokyo. But it's not my home, so I can't calm down. I wonder if my mother is aware that she also borrowed it, but she does not take a break from the housework and works hard. And as she looked at her mother, Yosio finally realized... that my mother is such a beautiful ass!
