Fixed and heavily whipped!

I have fixed my slave to the bed - he is stretched out on his front. Lying on his stomach, I have free access to his ass. I will now make his ass cheeks fiery red with my whip. He twists and turns, but he can't escape me. My strokes land well and his skin soon turns red. I lash out so hard that the whip really breaks on his ass cheeks. I show no mercy!
