I was just minding my own business, when I saw something that made me want to scream. My stepfather was fucking my twin sister. I was so overcome with anger and frustration, that I felt an insane urge to just put my hand down my pants and start jerking off. I mean, what else was I supposed to do?
My stepfather had his pants around his ankles and he was thrusting away at my twin sister like there was no tomorrow. Her moans and cries of pleasure told me that she was enjoying it, and that made me sick to my stomach. I wanted to run away and hide, but I just couldn't bring myself to do it. I was rooted to the spot, watching as my stepfather and twin sister enjoyed their naughty little moment.
All I could do was watch as my stepfather pounded away at her, and all I could think about was how I wanted to get naked and join in! I know it sounds crazy, but I just couldn't resist the urge. I wanted to make my stepfather pay for what he was doing, and in that moment, I thought the only way to do that was to strip off and join in. But of course, I didn't actually do it, I just stood there and watched as my stepfather and twin sister enjoyed their naked escapade.
It was one of the most intense, and yet strangely arousing, moments of my life. I wanted to look away, but I just couldn't. I just had to watch as my stepfather and twin sister got down and dirty. All I can say is that it was definitely an experience that I won't forget any time soon. Naked girls having sex is something I'll never forget!
