I've trapped the slave in the facetrampling box - basically making his face a part of my floor - and then walk on my floor with my sexy boots. The deep tread of my boots leaves bruises on the slave's skin as I walk back and forth on it, stand on it and enjoy the slave's pitiful screams. Then I take off the boots and trample his face under my nylon feet. Of course that's easier for the slave, but I'll make him suffer nevertheless! In the end I put one of the boots back on - I want to leave a distinct mark on the slave's forehead - the boot tread's star! After imprinting it on the slave's forehead I'll release him for today - but for the next few days everyone can see my boot tread on his face!
