Crushed Fingers Or Hard Face Spanks

I told the slave before that Im going to trample his mitts and fingers with my sexy over-knee boots. And if he dares to make a sound of agony Im going to penalize him by smacking his face - hard! So I begin to trample his fingers and albeit you can tell by his face that hes in a lot of anguish he manages to suffer in muffle - until I dig one of my heels into one of his fingertips! Of course he gets punished like I promised him - and then the hand trampling continues. My heels leave behind painful marks on his skin and his flesh turns white as my full weight comes down on his hands. How long am I going to make him suffer?!
