I've put the slave's hands in between some stuff to crush - some little toy trucks, some peanuts, a soda can, etc. - and then blindfold myself before I start walking over the stuff and his hands. I don't see what I'm stepping - or jumping - on and with the hard boot soles I don't feel what's under my feet neither. I crush everything in my path and in between order my camera girl to rearrange the slave's hands and the stuff as well! In the end even the camera girl walks over the slave's hands!
