Mijiri's mother is crazy about riding a horse.

The story of his son. Tatsuo Igarashi, his son who goes to university in Tokyo and lives alone. In order to rebuild the family, his cousin Yashiro TAIMI and his aunt Momoriko TAIMI were the families of their mother, Igarashi. In other words, he lives in Tatsuo's family. Tatsuo enjoyed his student life in Tokyo. And when I return home for a certain reason, my mother's beautiful buttocks that I had not noticed before are deprived of my heart. It was because it was dynamic and charming women's uplift enough to imagine a ride with my mother even if I moved a little.
