The Slave Cant Take That Much Poo

I use this slave for the very first time. He is untrained and wants just to munch my booty, but when my poo comes it doesnt ask... so I determined to use him as toilet and feces in his mouth in his very first time under my arse. I thought that it would be a small piece of shit, but when I started I couldnt stop shit long fat ropes in his mouth! He was so surprised and wanted to stop but when I start no one cant stops me!
