It was bad enough that my uncle was making me share a room with my step-cousin, but I also had to help her with her dance competition! I understood she was upset because the girls were making fun of her twerking, but I didn't see anything wrong with it. In fact, I liked it a little bit too much. Especially when she started twerking on top of my hard cock. Did she know I had a boner? Did she WANT that to happen? All the questions were rushing through my head. My dick was throbbing! The second she let me grab her tits, I didn't care anymore. She didn't think I would fuck her right there because she is my step-cousin. But if she's tempting me, moving her big ass like that, there's no way I'm not going to pound her raw.
