Shit To The Limit

Every day I use the slaves mouth for my needs. Every morning, as I wakes up, I pisses and drops smelly feces in his mouth. Today, I packed his mouth full of nasty feces. Do you want to be in his place? This slave is a perfect human toilet. He eats my shit and drinks my piss completely, without complaining, in fact he is excited when he does it, but now I want to crush his little dick...
