I shifted beneath you and heard you moan. You were on my lap, my cock inside you as we watched a movie. I'd told you I'd let you sit on my cock as long as you didn't move or touch yourself until the movie was over. What I didn't tell you was that I was going to keep "accidentally" starting the movie all over from the beginning. Your panties were soaked, and I could feel my pants getting soaked as well just from being inside you. There were moments where I felt your body relax, and it was then that I'd start the movie over or shift my hips so that I moved within you. It had been almost an hour, and we weren't anywhere close to finishing the movie.
From the corner of my eye I watched you bite your lip and very carefully, you lifted and slid down again. Without hesitation, I smacked your ass and bit into your shoulder. You whimpered and clutched my shirt with both your hands. My pants grew even wetter.
"Remember baby, not until the movie's off." I rubbed your ass where I'd just struck you, and your eyes closed momentarily.
"But daddy..." you began, your breath heavy. I wrapped my hand gently around your neck and shifted my hips again.
"Yes kitten?"
