Trampling:

My leather boots with thin, metal heels. You're feeling tense as you lie there on the floor, waiting until you can hear the clacking of my boots, the sign that I am coming. You can immediately feel my first step as it jabs your nipple, and my second step is near your cock. I am standing on top of you and will slowly increase the pressure.

The first time, I could stand on top of you with my bare feet, blocking your view by planting a foot on your face. It's only a matter of time until you'll be begging me to please put my boots on, because you want to experience it for yourself what it feels like to have your Mistress walk all over you.

What it feels like to be a doormat and to see how much you can take.
For yourself, and definitely for me, your Mistress.
