The niece I hadn't seen in a while had entered puberty and had developed an adult body. The allure of a woman in the process of growing up, which she didn't have as a child, made my uncle's reason explode into incestuous behavior. The more taboo it felt, the more lewd the niece became. In a situation where relatives could enter at any moment, sex with my niece couldn't stop. The sight of the niece experiencing her first orgasm. Her figure becoming obsessed with the penis is guaranteed to excite!
