Misha Cross is my stepsister and I could always feel the sexual tension between us, but I didn't know if she was feeling it too. As it happens, she is a horny beast, she has sex on her mind at all times and she gets caught all the time playing with herself. She has a fantasy of doing it with a big cock, but his was the last one in her mind at this time. She caught me watching her one afternoon when it was only me and her, and I knew if there was ever a time to make my move, it had to be right now. As I walked upstairs, I could hear her moaning and I knew what she was doing, she thought she was all alone again. I watched her as long as I could until my cock was about to burst out of my jeans. I slowly walked around to where she was and boy was she ever shocked, and maybe a little pissed. This did not last long though, she seen the bulge in my pants and knew my dick met her standards, so we slowly and cautiously started to toy with one another.
