I made it very clear to the slave after my last hiking trip that he was supposed to lick the dirty soles clean, but when I grabbed them today I saw the soles are still covered with dirt. Obviously, I can't tolerate this laziness. I put the slave into the face trampling box and start to walk over him with the boots. The deep tread hurts him a lot, but that's not my problem. I wouldn't punish him this way if he did like I told him! I'm walking over his face again and again and make him lick the dirty boot soles in between until they're are clean again and I think he has experienced enough pain as a punishment.
