Your face will now be used as my doormat! My hiking boots are pretty dirty - and I'll trample your face and wipe the hard tread on your skin until all the dirt is gone! In this deep tread there's always a lot of dirt collected. Oh, it hurts when I stand on your face with my full body weight and then even trample in place? That sounds like your problem! You'll endure the terrible pain and humiliation to please me, won't you?! Not that you'd have a choice, slave! And now stick out your tongue ... you'll lick the remaining dirt out of the boot tread ... and you better do your best - or I might stomp on your face as a punishment!
