Punishing schoolgirl for bad grades

A man leads a girl on a leash. And the leash from her chain. A man punished a schoolgirl by screwing her head to the pipe. Then he whipped his ass so that there were red stripes. Then he made her eat from a bowl on the floor, like a dog. He put a vibrator to the clitoris, and in the ass put her finger. He was playing with her until he was tired.
