My cute niece is in between a child and an adult, and her body is gradually becoming female through secondary puberty. Faced with the unique sex appeal that only a girl can exude as she turns from a beautiful girl to an adult, my reason breaks down and we end up in incest. In this situation where ethics are at a loss, my niece, whose body is not yet fully ripe, has her first orgasm from the sexual pleasure. You're sure to be excited by the lewd appearance of these loli nieces writhing in agony from the pleasure they've never experienced before!!
