My niece, who I hadn't seen in a long time, was entering puberty and developing an adult body... The innocence of her childhood mixed with the allure of a mature woman that she never had as a child was too much for my uncle's reason to resist, leading to incestuous sex. The more my niece felt the sense of transgression, the more unpleasant it became. Even in a situation where relatives could enter at any moment, her obsession with the penis and her excited state are thrilling!
