Hard jumps on slaves body in Vans shoes

The vid is rather short cuz of really hot weather, so i'm really tired of action, maybe more then my slave lol.  i'm in sadistic mood, so i'm trampling and jumping on my slaves poor body hard. there many tough jumps on his chest, especially running jumps on his ribcage with my full weight:) close to the end of the video i'm command him to lay on the stomach and continue jumping repeatedly on his back.
