Mistress had always been known for her unique sense of humor and twisted ways to extract pleasure from others. Today was no different. As she gazed down at her slave, there was an unmistakable glint in her eye that sent shivers down his spine. She stood before him, wearing nothing but a pair of black lace panties and a sinister smile that said she was up to something.
"Today, my dear slave," she purred, "I want to make you happy. And what could make you happier than allowing you to cum?"
He couldn't believe his ears. He had never dared to dream that such a thing would ever be possible. His heart raced with anticipation as he tried not to show how excited he was. He had always been loyal to her, obeying her every command without question or hesitation. There had to be a catch.
"But there is a condition," she continued, "and it's one that I'm sure you'll enjoy." She paused for dramatic effect, her smile widening. "You must be a good potty for me. Drink all of my pee and act as my shitting pot while you cum."
Her words hit him like a ton of bricks. This was not what he had expected at all. It took all of his self-control not to gag at the thought of drinking her urine and being used as a toilet during his climax. But he couldn't disobey her. Not even in his wildest dreams could he imagine refusing her demands.
"Yes, Mistress," he managed to choke out. "I will do as you say."
She nodded curtly and turned around, presenting her backside to him. He could see the dark stain spreading in her panties - evidence of what awaited him. Trembling slightly, he moved forward and opened wide his mouth, revealing his tongue. Slowly, she lowered herself onto him, grinding her hips against his face until he felt the warmth of her urine against his tongue. The taste was bitter and acrid, but he didn't dare spill a drop.
As he drank, he could feel her growing impatience. She groaned and pushed him away, dismissing him. He watched as she walked over to her toilet bowl, her hips swaying enticingly. She squatted over it, her bare ass in full view.
"Now, slave," she ordered. "Prove yourself worthy."
He knew what he had to do. He moved forward, positioning himself behind her. He let out a shaky breath as he slid his cock between her plump cheeks, feeling the warmth of her body against his shaft. Slowly, steadily, he began to stroke, imagining the feeling of her shit splattering down on him as he grew closer to climax.
Mistress grunted and moaned, encouraging him to go harder. Her ass spasmed and clenched around him, milking his cock with every movement. His mind was a blur of lust and desire as he lost himself in the moment. He couldn't believe how turned on he was by this newfound taboo pleasure.
Finally, after what felt like an eternity, he felt his balls draw up tight against his body. He groaned, feeling the overwhelming urge to release. With one final thrust, he emptied himself deep into her ass, groaning loudly as he did so. He could feel the hot rush of his cum shooting up his spine, filling him with an indescribable sense of ecstasy.
As he collapsed, spent, next to her, he looked up to see Mistress watching him intently. She gave a slow clap, an approving smile spreading across her face.
"Well done, slave. You've proven yourself once again that you're willing to do whatever it takes to please me." She walked over to him, knelt down, and tenderly caressed his cheek. "You make a very good shitting pot."
He couldn't muster the words to reply. All he could do was nod, still reeling from the intense mix of pleasure and humiliation that coursed through his body. She got up, picked up a pair of scissors from the nearby table, and snipped away the soiled panties from her body before walking out of the room.
As he lay there, staring up at the ceiling, he couldn't help but wonder what she had planned for him next. Whatever it was, he knew one thing for sure - he would do it, because he was hers.
