While driving I realize that I  really have to poop. Of course I want to use him as my toilet! He has to  stop the car and I sit on his face. Almost immediately there is a huge  piece of shit coming out of my perfect ass! I shove it in his mouth! I  don't care if he pukes! If I have to poop, my slave has to obey. There  isn't any toilet paper, so I use his tongue.  Let's go!
