My hiking boots are totally muddy after a nice long walk in the woods and I haven't cleaned them yet. I walk up to my slave while holding the boots in my hands and I put the first one on. I put my foot on his face while I tie the shoe and after putting on the second shoe as well, I get on his naked chest and clean my boots on his skin. I also step on his head and use his face as a doormat for my muddy boots. In the end, his chest and face are completely covered in mud and my boots are more or less clean.
