Yutaka comes to visit his friend's house.So I happened to see his older sister Aki's glossy naked body after taking a bath, and I was so nervous and excited that I erected my cock.Aki who saw it played happily with his crotch because she could not suppress the pain of her body that had accumulated while living away from her husband who was on a single assignment.Aki was satisfied with her virgin Yutaka's desire, but Yutaka, who had awakened to her sexual pleasure, was not satisfied with that alone.
