VEC-251 Yuka Mayama, the mother of a friend

Forgetting that her son's friend, Tatsuya, is coming to stay, Yuka flutters with a bath towel after taking a bath as usual. Then Tatsuya approached with an uncontrollable excitement and asked for Yuka's body. Although she barely refused to insert it, Tatsuya stayed at the Mayama family again a few days later ... He tells his unknowing son, "Do you know your aunt is frustrated and flirtatious?" In a hurry, he drives out his son and forgives Tatsuya to protect his family.
