Vanessa Vaughn, a formidable Mistress known for her dominance and humiliation fetish, had a new toy up her sleeve. Today, she was going to test out a piss gag on her submissive slave, Alex. The device consisted of a rubber funnel attached to a thin tube that fit snugly between Alex's lips. With a click of her tongue, Vanessa adjusted the aperture of the funnel so that it comfortably enveloped her slave's mouth.
With a mischievous glint in her eye, Vanessa approached Alex, who lay bound on the cold stone floor of her dungeon. Her heart began to race as she felt him squirm beneath her grasp. Slowly, she lowered herself onto her haunches and positioned the opening of the device just above his mouth. A foul, musky smell wafted up towards her nose as she did so, an unmistakable sign that Alex was scared shitless.
"Now, Alexander," she purred, her voice dripping with venom, "you are going to swallow every single drop of my golden nectar."
Alex whimpered in fear at the thought of what was to come, but there was nothing he could do but obey. Slowly, Vanessa began to urinate into the funnel from the height afforded by her perch above him. The stream of urine snaked its way down into the funnel and into his mouth, filling it with the warm, noxious liquid. To make matters worse, she'd instructed him not to spit it out, under pain of severe punishment.
As the urine filled his mouth and began to trickle down his throat, Alex gagged and choked. The taste was unlike anything he'd ever experienced - concentrated and tart, with a tang that made his eyes water. But he forced himself to keep swallowing, feeling the cool liquid slide down his throat and into his stomach. He could feel it pooling there, burning and churning like acid.
Throughout this ordeal, Vanessa remained impassive, her face a mask of indifference as she watched the slave suffer under her control. She knew this was exactly what he deserved - to be reduced to a mere vessel for her piss and humiliation. With a final sigh of satisfaction, she pulled the device out of his mouth and stood up to assess the damage.
"Well, Alex," she said, stroking her chin thoughtfully, "I have to say, I'm quite impressed with how well you were able to handle that." She paused for a moment, a wicked grin spreading across her face. "I think we'll be using this gag every time I need to go to the toilet from now on."
As she walked away, leaving Alex to contemplate his mortification and the stinging ache in his now-swollen crotch, Vanessa felt a powerful thrill coursing through her veins. This, she thought to herself, was why she did what she did - because there was no greater rush than dominating another human being and making them beg for more.
