VEC-647 My Mother's Best Friend Miki Yamase

Koji is left in charge of his parents' home while they are away on a trip. His mother's best friend, Miki, comes to check on him because she is worried about him being alone. Koji develops feelings for her as a member of the opposite sex. He wants to make some adult memories with Miki, no matter what. With evil intentions, he sneaks into the changing room and uses her underwear as a masturbation aid, but unfortunately he bumps into Miki. However, rather than getting angry, Miki presses her breasts against him, saying, "Is this what you wanted to do with me?"
