I ordered the slave to put his hands on the doormat - and then start trampling his hands with my hard deep-treaded CAT boots. I walk, stomp, jump and grind all over his fragile hands and fingers - and my boots leave a nice imprint on his skin with every step. It's just so much fun to apply pressure to his hands until he starts to moan in pain - and then increase the pressure to make him scream :-D In the end his hands are completely bruised and you can see hundreds of imprints overlapping each other!
