It was a warm summer evening, and Mistress Anna was relaxing in her luxurious bathroom. She had just finished a sumptuous dinner and felt the urge to empty her bowels. Her thoughts turned to her devoted slave, who had been preparing for this moment for the past two weeks.
The slave had been living in chastity for the duration, his cock trapped in a tight metal cage that prevented him from experiencing any pleasure. The anticipation of providing his mistress with a warm stream of urine to wash her feet had kept him on edge this entire time.
Mistress Anna stepped out of the tub, her flawless, bare skin glistening with droplets of water. She walked over to her unsuspecting slave, who was kneeling before her, eyes downcast in submission.
"You are such a dirty little toilet," she purred, running her fingers through his hair. "It's time to clean you out."
She kneeled behind him and gently pressed his face against her asshole. She felt his warm breath on her skin, and smiled as she savored the moment. Slowly, she lowered his head, sealing his mouth over her anus. With a delighted moan, she began to defecate, feeling the heat from his breath against her behind.
As the shit started flowing into his mouth, the slave immediately began to gag but couldn't pull away. He knew that this was his punishment, and he would have to endure it. He tried to swallow as much as he could, hoping it would at least lessen the taste in his mouth.
Mistress Anna watched with detached amusement as her slave struggled to cope with her enormous turd. When she was finally satisfied, she pulled his head roughly back and unlocked the chastity device. With a visibly shaking hand, he freed his cock from its confinement, breathing in the scent of his mistress's ass as he rubbed it against his chest.
"Now, clean my asshole," she commanded, turning her attention back to the toilet where her huge turd floated. She watched with a sinister grin as the slave lowered his head and began to lick her clean. He savored the taste of his own semen mixed with his mistress's shit, knowing that this was his ultimate submission.
As he ran his tongue over every inch of her anus, wiping away the last traces of remain, Mistress Anna reached down and stroked his cock gently. "Such a good little toilet," she murmured, her lips brushing against his ear. "Now, why don't you clean yourself up and be ready for me?"
The slave looked up at her, his eyes brimming with tears of humiliation and arousal. He nodded, unable to speak, and turned to the shower to wash off the remnants of their intimate encounter. Mistress Anna knew that she had broken him completely, and she couldn't help but feel a twinge of satisfaction. After all, a loyal slave is a slave who will do anything for his mistress.
