A new housekeeper has arrived at Umao's house. When I looked into the housekeeper's toilet with a prank, I found that the shape was different from ours.

Innocent and free-spirited, but only there is a big cock boy Umao's aunt observation masochistic drama that hangs a big cock that is as good as an adult! Free point gift for the first 1,000 yen!
