My stepfather, who was born after my mother remarried, stripped my sister of her panties and made her completely naked, claiming it was a form of discipline. I was right next to her, but I didn't help her because I didn't have the courage? No... I wanted to see my sister being violated by my perverted stepfather! I secretly watched my sister cumming on my stepfather's dick and got a depressed erection, which gradually turned into a dirty erection with a vile desire to violate him too... You want to do it too, don't you? With one unexpected word from my stepfather, I was lucky to insert and cum inside my reluctant sister! This is what I wanted (lol).
