VEC-251 My Friend's Mother Yuka Mayama

Forgetting that her son's friend, Tatsuya, is staying the night, Yuka is dizzy with just one bath towel after taking a bath as usual. Then Tatsuya approached her with a look that she couldn't control her excitement, and she asked for Yuka's body. She barely refuses to let her in, but Tatsuya returns to stay at the Mayama family a few days later... He says to his ignorant son, "Did you know your aunt is cheating on you because she's frustrated?" He kicks out her son in a hurry and allows Tatsuya to protect her home.
