He's used to being Filled Up

Mercy has the cage set up so she can sit on it and the slaves head is sticking out between her legs. "I've been so pleased with him I decided to give him a rare treat", she says. She spreads her legs and you can see the slave has his nose right against her pussy. Panties in between of course, he can get close but not that close. Mercy pulls back and says 10 seconds is all he gets but if he works hard maybe he'll get another sniff in a month.

Now it is time for the slave to put his nose where it belongs, in her ass crack. "That's his real purpose", Mercy says adding "Kissing my ass, sniffing my ass, licking my ass, smelling my farts, but what he really wants is for me to take a big dump in his mouth." She leans on her side and presses her ass cheeks into his face and he instinctively gets his nose in her crack. "I remember the first time I filled him up he got a bit sick but now he is used to it and he can eat as much as he likes." Mercy pulls the fabric of her panties away from her butt hole and in short order lets out three nice farts. "If I do my business now you better not make a mess or you'll be in big trouble" she tells him. She then turns into a reverse position so she is sitting on the slaves face. She wiggles and gyrates her ass and it looks amazing and then she farts again. She then shifts further back so his head is now flat on the surface of the bench and really smothers him. "I want to feel your tongue deep up my ass to loosen me up" she tells him. She tells him to open his mouth and then she grunts. She says she will have to push his cage into a closet because it's going to be awfully stinky by morning.
