I like to use the slave in a toilet. Here he feels at home. I instruction him to eat my ass hole. He comes deep in my booty with his tongue and already feels taste of bitterish poo, reaching a tongue peak my crap. Then he opens a mouth and I pack it with my delicious poop. I sit down on his face and strangle him that he get used a smell and taste of my shit. Thus I accustom the slave to a toilet to that he could absorb my shit easily and in a big portion because I have a lot of shit.
