Used As Toilet Part 3

My slave serves me as often as a chauffeur. As we drive, I realize that I truly have to poo, but there is no toilet in glance. Of course, he has to serve me as my toilet. I squat over his face and start immediately. His mouth is stuffed with a pile of shit. He chokes, but I do not care.. Since no toilet paper is within reach, I use his tongue to wipe my ass.
