Black boots with spikes and high heels are what these sadosisters use to torture their slave. He is on his stomach while they take turns trampling his back then he turns over and let them walk up and down his check and stomp on his face too. Afterwards they torture him some more by making him lick their shoes and boots clean.
Her muscular slave is doing pushups. She wants to see if he can balance her on his back while she is in a mini dress and black boots. The heels is digging deep into his back but he keeps doing the pushups as if she is not on his back. She attempts to jump on his back. And laughs when she nearly falls off his back.
