Under the harsh fluorescent lights of the bathroom, Mistress Mystique stood naked before her shivering slave. Her body gleamed with sweat and anticipation as she placed a call on her smartphone. She waited impatiently for her caller to pick up. It was time for him to answer his Mistress's call of nature.
As the phone rang, she heard him whimper softly from the other room. He knew what this call meant. It meant he was about to become her toilet, her human sewer pipe. She took a moment to savor the power she held over him, the ability to make him crawl and beg for her permission to clean her ass with his mouth.
Finally, the call was answered, and she spoke in a low, commanding voice. "Get in here, slave," she ordered. Her words sent shivers down his spine as he stepped into the bathroom and knelt before her, his eyes fixed on the enormous bulge in her panties.
"Please, Mistress..." he whispered, his voice trembling.
"Please what, slave?" She purred, knowing full well that he wanted to worship her ass and taste her shit. She raised her hand, nodding towards her bulging crotch. "You know what you have to do."
The slave nodded slowly, his cock already hard in anticipation of what was to come. He could feel his saliva starting to pool in his mouth as he reached out hesitantly towards her crotch. As his fingers touched the cold silk of her underwear, he gasped at the heat that burned through them. This was no mere woman he was serving; this was a goddess among humans.
With shaking hands, he began to tug at the waistband of her panties, pulling them down to reveal her perfect, round ass. Her cheeks were plump and inviting, already starting to twitch with the effort of containing her massive shit. He leaned forward eagerly, his tongue ready to do its duty.
Mistress Mystique looked down at him with satisfaction as he positioned his tongue at the tight entrance to her asshole. "Taste it," she commanded, releasing her bowels.
A torrent of hot, thick shit poured out of her asshole, coating his tongue and filling his mouth with the deliciously filthy taste of her feces. He lapped at her hole, cleaning it as best he could while she grinned down at him, savoring the sight of him kneeling before her, worshiping her most intimate parts.
As the slave continued to clean her ass with his tongue, she reached down and cupped his hard dick through his pants. "Now," she said, her voice straining with desire. "Now you can cum all over yourself."
And with that, she pushed him forward, sending his head crashing against the toilet bowl as he exploded in a shower of hot cum. His cries of pleasure echoed off the tiles as he tasted both his own cum and the remnants of her shit.
Satisfied, Mistress Mystique finally relieved herself of the last of her load, her tongue cleaning the insides of her asshole with expert precision. She stepped away from her slave, grabbing a towel to wipe her ass clean. "You may go now," she said dismissively, turning to leave the bathroom.
The slave stumbled out behind her, his eyes fixed on the sway of her hips, the scent of shit and cum clinging to him. He knew this was the life he wanted, to serve and be used by a goddess like Mistress Mystique. And as he lay awake in his bed that night, he couldn't help but wonder what other dirty, depraved acts she would command him to perform.
