Battered and Desperate.

Miss Muscle has her slaves balls right where she wants them, locked in her ball trample table. She has a rope wrapped around his balls so she can pull on them as well as step on them. She starts by stepping on him with her sneakers before removing them and making him sniff them. She then makes him open his mouth and she stuffs one of the sneakers in it to muffle his screams while she crushes his cock and balls under her feet. She spits on it and rubs it with her feet to get it hard so he suffers more when she steps on it.
