I know that I'm twisted in wanting to impregnate my sister Lili. But I don't know how to stop it. All I can think about is impregnating Lili. But... is it because I'm infertile that she doesn't get pregnant even when I cum inside her? But since I can't go to the hospital, I decided to carry out a plan to find out. So, for this plan, I decided to use my friend, my father, and the guy Lili has a crush on. Cute Lili gets treated like a public toilet. But I'm definitely going to do it with her until she's pregnant. I want to see more of cute Lili's twisted face... and, oh, I want to impregnate her soon!!
