As soon as step-daddy told me to get on my knees, I knew what was in store for me. I was ready to submit and worship his big thick white cock, and step-daddy knew how to keep me motivated. I had to take a few slaps in the face to get me warmed up, but after that I knew my place. I was step-daddy's little nasty obedient slut and was dripping wet just thinking about the next thing he would do to me.
