I order the slave to put his hands on the metal grid and then start to walk over his hands. The soles of my sexy boots crush his fingers into the grid and the loser starts to scream in pain. He's obviously not only in pain but also afraid I might break his fingers ;-) After a while I decide to show some mercy and he's allowed to put his hands on the wooden floor - but of course the hand trampling continues. In the end you can see how badly bruised his hands are!
