I come home after a walk in the park with friends. My slave is waiting for me laying down like a doormat and I explain to him that I really need a mat because my shoes are all dirty with mud, real and filthy mud. I get on top of him, rub my shoes a little to clean them and his chest starts to turn brown. I enjoy it and keep walking back and forth, I like to hear the sound of the mud between my soles and his skin. I also get on his face, crush it, dirty it and leave brown marks on his cheeks. Still not entirely happy, I order him to open his mouth and lick my shoes to complete the cleaning and in the end I want to see his tongue filthy and brown.
