Des:Nanami, a niece, came to stay at the house of part-time worker Yamada, who only thinks about butts. Nanami-chan doesnt listen to other peoples stories, and all she does is play games all day long. Nanami-chan exposes her beautiful butt defenselessly... Yamada cant hold back and buries his face in Nanamis butt... At first he was surprised by her sudden act, but from the middle he started to enjoy it and instead asked for more, as if toying with the old man... From that day on, a secret relationship between the two began.
