He's used to being Filled Up

Mercy has the cage positioned perfectly so she can sit atop it comfortably, the slave’s head protruding straight up between her spread thighs. “I’ve been so pleased with his progress,” she says with a wicked smile, “that I decided to give him a rare treat.” She lowers herself until his nose presses right against the thin fabric of her panties, letting him inhale the warm scent of her pussy for just ten seconds before pulling away. “That’s all he gets today. If he works very hard, maybe he’ll earn another sniff in a month.”

Now it’s time for the slave to serve his real purpose. “Kissing my ass, sniffing my ass, licking my ass, breathing in my farts… but what he truly craves is for me to take a big dump right in his mouth,” Mercy declares. She shifts onto her side and presses her soft cheeks firmly against his face, forcing his nose deep into her crack. Hooking her panties aside, she releases three long, warm farts directly onto him, then swings into a full reverse facesitting position. She wiggles and gyrates her perfect ass, smothering him completely as another deep fart vibrates against his face. Shifting further back to pin his head flat against the bench, she commands, “Push your tongue deep up my ass and loosen me up.” As he opens his mouth wide, she grunts with effort. “I’ll have to roll your cage into the closet tonight,” she laughs. “It’s going to be awfully stinky in here by morning.”
