Heavy sadistic trample on small slave

There's a competition between my domme friends and I want the first prize! The game is to show off how much damage we can do to our slaves by trampling them for a whole week. Whoever has the slave with the most bruises and injuries wins! That means I need to stomp Kitten into oblivion in my coarse rainbow platform shoes. He complains and hates the idea but doesn't get any say in the matter. I make him comply and he lies down for his suffering to begin. I step on him over and over while gleefuilly berating him. His face turns purple and vision goes blurry as I compress his organs beneath my full 115 kg of weight against the solid floor. Sweat pools all over him like I'm wringing out a towel. He could literally burst at any moment and all I care about is beating up his chest and stomach.
