I make my slave lie down on the ground with his hands on the metal grate then I get on the grate with my sexy leather boots. When I step on the slaves hands he screams in pain because he got my full weight from the top and the sharp metal from below! Again and again I walk over his hands, keep standing on them or dig my heels into his palms. In the end I even make him kiss the boots that just caused him so much pain.
