Tokita Ami goes to her uncle's house for a few days because her father is absent. Because he was often sent here when he was a child, he dresses quite comfortably. She even read her uncle's sex stories. Seeing his niece growing older and more beautiful, this uncle also had a bad intention, but before he had any bad intentions, this niece was the one who actively solicited him. Then the two later had incest next to each other.
