As the round-assed Leather Goddess stood over her kneeling slave, she couldn't resist the urge to show off her dominance. She moaned softly, her heavily pierced and tattooed body quivering with excitement as she let out a long, slow fart. The putrid stench wafted through the air, making the slave's mouth water involuntarily. With a devious grin, the Goddess leaned down and whispered in his ear.
"You've been such a good little slave, I think you've earned a treat," she purred, her breath tickling his ear as she nudged his head towards her ass. "Open wide and say 'ah'."
The slave obeyed without hesitation, his tongue tracing the line of her crack as he eagerly anticipated the pungent rush of her fart. She moaned again, this time more loudly, and released a blast of hot, stinking air directly into his open mouth. He gagged on the overpowering stench, but swallowed instinctively as he felt his slave cock twitch in anticipation.
"Good boy," she praised, patting him on the head condescendingly. "Now how about a real reward?"
She rose up onto her tip-toes, maneuvering her massive bowel movement into position. The slave could hear it sloshing audibly behind her, accompanied by an even stronger wave of nauseating gas. Then, with a final whispered incantation of dominance, she unleashed a torrent of shit straight into his waiting mouth.
It was hot and heavy, filling his entire mouth and forcing his jaw to strain. He groaned around it, feeling her shit coating the inside of his cheeks and slipping down his throat. As he swallowed, her ass clenched again, and he felt another blast of gas hit his tongue.
"That's it," she breathed, her voice thick with lust. "You love this, don't you? Swallowing your mistress's shit."
The slave could hardly form a reply as she continued to fill his mouth with her waste and alternate between farting directly into it and into his face. His slave cock twitched in approval despite the overwhelming stench that filled the room. He reached down and began to jerk off, still unable to bring himself to touch his ass, but feeling the heat and moisture of his own arousal as it soaked into his shorts.
Finally, the Goddess pulled away, leaving him gasping and panting with excitement. He looked up at her, his eyes glassy with lust, though his face was still covered in her shit and ass-juice. She smiled down at him, a beatific expression of dominance on her face.
"That's a good boy," she purred again. "Now clean yourself up and get ready for the next round."
With that, she turned and strutted away, her enormous ass swaying hypnotically in the air. The slave remained kneeling in the filth, his mind reeling with the mix of pleasure and humiliation he had just experienced. He knew he would do anything to return to that moment - to feel her shit filling his mouth and her gas filling his lungs. He couldn't wait for the next time she called upon him to swallow her divine shit.
