My mother's friend

Hana, a mother's friend who has moved to Tokyo to help her child move, comes to stay overnight, and her son Yasuo can't contain his excitement. The night is late and the atmosphere gets excited, but her mother kicks her out and says, "It's time for adults," and Hana comes to Yasuo's room, who is in agony and in high spirits. While listening to the story, Yasuo was nervous, and his crotch was bulging out. Hana noticed this and smiled and kissed her. Then she left the room and said, "The rest will be after mom goes to sleep."
