If stepmom only knew

When I recently came home from university, I was really annoyed. I sat down on the sofa and started reading a book when my stepfather came in and sat next to me. Somehow I've always been secretly horny for him and when I looked over at him, I thought to myself that maybe I should put my book down and see if something's going on. Of course, my stepmother shouldn't notice anything about it, but he's always had the thought of doing it really wild with me! We forgot my mother for a while and fucked wildly and uninhibitedly on the sofa in all possible positions until the horny buck shot all his cum deep down my throat at the end, just the way I love it!!!! After that, we and both promised that my stepmom would never know anything about it.
