Mistress Nyx, a stunningly beautiful and absolutely dominating woman, sat on her throne-like chair overlooking the bewildered slave kneeling before her. The slave's eyes were fixed on her, his breathing heavy with anticipation of what she might demand of him next.
"You know," Mistress Nyx purred, savoring the power she held over the pathetic worm at her feet, "I've been feeling rather uncomfortable lately. Something doesn't quite feel right down there." She leaned forward, hand moving to probe at her distended belly, which was stretched tight over her toned abdominals.
"Your Majesty..." the slave began, voice trembling in fear.
"Don't bother trying to speak," she hissed, smirking wickedly. "I know you only exist to serve me. Now shut up and open your mouth."
Ignoring the slave's protests, Mistress Nyx reached down and grabbed hold of his head, pressing his face firmly against her swollen belly. Her stomach was warm and comforting against his cool cheek, but it was also throbbing with potential power.
"Inhale," she commanded, her breathing deepening as she focused on releasing the air pent up inside her. "Drink in my farts... make them a part of you."
With great effort, Mistress Nyx strained to push out the trapped air from her belly, releasing one enormous stinker after another into the willing face of her slave. The noxious gasses filled his nostrils, making him cough and sputter, but he could do nothing to escape their power.
"But Mistress," he gasped between breaths, "they're so... so loud!"
"I know," she chuckled smugly. "Isn't it wonderful?"
With each passing moment, more farts came pouring out of Mistress Nyx's ass, each one louder than the last. The slave struggled to keep up, his lungs burning from the overwhelming stench around him. But still, he couldn't help but feel a perverse sense of pleasure in serving her in this way.
Finally, after what felt like an eternity to the increasingly lightheaded slave, Mistress Nyx's body relaxed, no longer straining to expel the air that had built up inside her. With a satisfied smile, she pulled her face away from his and sat back in her chair.
"That's better," she sighed contentedly, running a satisfied hand over her slightly flattened belly. "You can recover now."
As the haze cleared from his mind, the slave looked at his Mistress with renewed awe. No matter how disgusting or demeaning her demands might be, he knew that he would always come when she called, and serve her faithfully. Because in the end, there was nothing more fulfilling than being used by a beautiful and powerful being like Mistress Nyx.
