Miss Medeas dirty store - I make him lick Dirt mixed with Piss from my Feet

My slave brings me a collection of the finest dirt: Dust, Ash & Fluff. I will put this onto my feet and make him lick it off with his tongue! I enrich the dirt with my divine spit and piss, so it sticks better to my soles. My slave finds it really disgusting, but I want him to keep licking, until my feet are clean. Today he will swallow a lot of dirty for me. In the end, I realize that he will never be able to lick it all off, so I pour the entire piss & dust mixture into his mouth. That´s what a dirty boy like him deserves!
