Ive placed a bunch of small things to crush on the floor and make my slave sit down in front of the pile. I walk over his hands a few times – then reveal what Im really planning to do! I move his hands between the stuff to crush and then put a blindfold on myself. Now I start to walk back and forth – crushing stuff and trampling the slaves hands under my boot soles. Of course this might hurt way more than usual since I dont see what Im stepping on – and sometimes hit his fingers with only the edge of my heel or crush a piece of plastic into his hand 😀 In the end I take off the blindfold and put it over the slaves eyes instead – and then continue the brutal finger trampling as hes really afraid and in pain!
