I stop in the parking lot and have the slave lounging at my feet. I pull him out of the car and make him lie down his forearms on the ground. Then I embark to trample his mitts under my boot soles. The sharp stones on the ground hurt one side of his hands - the deep treaded hard soles of my boots the other one! Then I open the drivers door and put his hands on the step - there I can perfectly trampling them as well as I walk in and out of the car!
