Blindfolded Forearm Trampling And Crush

I put some stuff to crush on the ground and brought along a blindfold. Very first, I blindfold the slave, place his forearms inbetween the stuff on the ground and then begin to trample his arms and crush the stuff inbetween his fingers under my boots! Of course, he now cant see where Im going to step... and he never knows whats coming! Without knowing whats going to happen, hes even more appalled than usual :-D After a few minutes I take off the slaves blindfold - and he thinks the worst is over - but now Im going to put the blindfold on myself - so I dont know if Im going to step on a finger or on something else to crush :-D Obviously now the slave is even more appalled - because I dont know if and how Im going to step on his palms. Do I hit him with the sole? Or the heel? Or maybe just the edge?! :-D.
