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 malicious intentions, 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.
