You'll have to be My Toilet, Fart sniffer

"I'm so gassy today" says super sexy Mistress Mercy as the camera zooms out and we see her luscious plumb ass in her slaves face, who is locked in the cage, with only his head exposed, and right on cue she lets out a ripper. The slave instinctively turns his head and groans but Mercy orders him to sniff it up. Farts are a treat and should never be wasted. She shifts up on the cage and pulls his head towards her ass cheeks before farting again. Her farts sound so heavenly. Mercy feels the slave is not appreciative enough and says she knows many slaves that would gladly take his place. Like you for example.  She then asks the slave if he wants to rim her hole and when he says yes she replies "You know when you get your tongue up my ass I'm going to have to take a dump."

Mercy says the slave has been eating her waste for years but he is to shy to admit it. "He probably hasn't even told his family yet" she adds. Mercy tells him he should be proud. She then gets up on the cage so she can face sit the slave and lets out a huge fart. Damn, her ass looks amazing. The slave now eagerly sniffs and licks. She farts again. Mercy says it feels nice farting and being licked and she decides to touch her pussy. She farts again and this one does sound pretty wet. She bounces her ass on his face. She farts one more time before turning around to face the slave. Se tells him to close his eyes because she doesn't want him looking at her pussy. She grinds his nose into her asshole and plays with her clit. She says her pussy probably doesn't even turn him on because he knows he is only good for licking dirty asses. She then orders him to open his mouth because she is going to dump in his mouth. Mercy grunts and the slave struggles being her toilet. "Is it too much for your mouth?" she asks him. She leans over and farts in his face again and says she has enough left over to go feed another slave. She walks from the room.
