As Mistress Anna lay on the toilet seat, her stomach rumbled heavily. She had been ill for a few days and her slaves had faithfully attended to her every need, unaware of the delicious surprise that awaited them.
Anna looked down at her swollen, distended belly and sighed. "I was sick, but now it's time to eat something tastier," she muttered to herself, feeling a burst of anticipation in her gut. She couldn't hold it in any longer; the urge to empty herself was overwhelming.
She raised her hand and commanded, "Slave, open your mouth wide."
The slave, whose name was Mark, dropped to his knees in front of her and lowered his mouth. His eyes widened as he saw what was coming, for even from this distance, he could see the HUGE, STEAMING, SEPTIC balls of diarrhea forming in their mother's bowels.
"Oh, no..." he whimpered softly. He knew this was going to be huge.
Mistress Anna pushed with all her might, feeling the burning turmoil in her gut. The first glob of sticky, yellow, stinky diarrhea hit Mark's lips, followed by a second and a third. He choked on the thick, foul liquid, but his mistress's command left him with no choice.
"Swallow it, slave," she growled, pushing another mouthful of diarrhea into his gaping mouth. Mark gagged but swallowed obediently, feeling his stomach churn with revulsion as it struggled to digest what was coming.
Mistress Anna let out a loud moan of satisfaction, feeling the diarrhea course through her veins like a drug. She couldn't help but feel the stirrings of her desires, knowing that she was about to cum while her slave licked her ass.
"Oh, yes!" she cried out, pushing herself deeper into her slave's face. His tongue flicked out to lap at her anus, and she felt the first spasms of her orgasm course through her body.
With a loud, undignified groan, Mistress Anna unleashed a torrent of hot, sticky, thick sperm into her slave's mouth. He gagged on the first few spurts, but managed to force it back down his throat as more and more of her essence poured into him.
Finally, it was over. Mistress Anna collapsed back onto the toilet seat, panting heavily. Mark crawled back on all fours, his mouth still filled with the taste of his mistress's fluids. He looked up at her, eyes brimming with tears of humiliation, and whispered, "Thank you, Mistress..."
Anna smiled down at him, feeling a twinge of sadness mixed with her satisfaction. She knew this was not the life Mark wanted, but it was all he knew how to do. And as much as she hated to admit it, she needed him. He was her slave, and she was his mistress. There could be no other way.
