Jill has a new slave. She want to test his strength with trampling.
She begins with red high-heeled sandals, steps fullweight on his body, walks on him and let sink the sharp heels deep in his flesh, she drives him to his limits of pain.
Then she removes the sharp weapons and tramples him in her nylon.
All this in a harsh sadistc way, including bouncing and jumping (with her heels on) on his poor body.
