A story about a brother. Due to the renovation of the house, the second son, Yuki Yasuhiro, and the mother, Yuki Natsumi, are freeloading at the house of her real sister, Anna Machimura. The situation where he is renting a room from his cousin, Tatsuo Machimura, who goes to a university in Tokyo and lives alone. However, it's not my own house, so I'm somewhat restless. Her mother may be aware that she is still living on rent, but she does her best to do the housework without taking a break. And while looking at his mother, Yasuhiro noticed something... And the eldest son, Yohei, has also noticed... That my mother is ridiculously beautiful ass! !
