Ms. Mayumi, an educated mother, taught her son Takashi a lot of hard work every day. One day, when my mother noticed an email from a friend of hers while she was studying, she opened the email and found a picture of a woman's big tits. Mayumi thought that it was because of the evil of adolescence that his grades did not improve no matter how much he studied, but he tried to get rid of his son's splendid evil, but once on his son's bar.
