I've put on my CAT boots with a mean tread to the slave today. I will test out what's more painful for him - standing on his hands with my full weight for a long time?! Or maybe stomping down onto his hands?! Or maybe jumping on his hands?! :-D I know all of these will hurt him extremely and it doesn't take long until his hands are completely covered in marks from the boots' tread. I just love how the skin under my boot soles turns white and red under the pressure and I also enjoy hearing the loser scream in pain, beg for mercy and almost cry in despair!
