Two busty asses will fill that mouth up - that's gonna be reeeally nasty! They held the shit over hours inside their intestines just to serve the biggest amount possible to their slave. He already waits for the foul mass to enter his mouth, when his two queens sit down on their throne. That smells absolutely brutal.. but he has sworn to serve his queens and that's how they want it to happen.
Mistress Gaia locked her houseslave away and lets her suffer a while, far away from the tasty shit of her mistress. And believe it or not, her slave would rather resign to massage her own pussy than to her mistresses shit. The happier the slavebitch gets as Mistress Gaia shows her the dog bowl with a tasty meal inside - at last! Her greedy mouth awaits Gaia's sweets and eats every little piece.
Mistress Victoria dispenses her slave his daily portion of shit in the bathrub. While she's sitting on the cold edge, he receives her turds with his mouth open and lying directly under her asshole. He loves her scat and even pushes it avidly between his teeth. That's a good slave. He knows how to serve his mistress to her perfect satisfaction. And she is willing to give him as much reward-shitting as he deserves.
He was curious about eating shit. So she will give him the privilege to try it out and shits everything she's got out straight onto his face. If he knew what it would be like? Surely not. She's smearing her shit on his face so that his mouth and nose are covered completely, and gives him some shit on a spoon to eat, too. What he didn't know- she won't be the last girl using him as a toilet slave from now on! This is his new destination.
