As the evening drew near, the anticipation grew stronger within toilet slave. Today was the day he had been training for, the day he would finally earn the coveted title of Mistress Michelle's "toilet mouth." He would be privileged to serve as her personal receptacle for bodily waste, welcoming her urine and her feces into his mouth with utmost devotion.
The room was dimly lit, casting eerie shadows across the cold, hard floor. The walls were adorned with images of scatological fetishism, depicting scenes of dominance and submission involving human waste. The scent of disinfectant assaulted his senses, attempting to mask the true purpose of the room.
The toilet slave crawled on his hands and knees towards the toilet, his heart racing in his chest. As he reached under the toilet chair, he could feel the warmth emanating from Mistress Michelle's body. She was already standing above him, preparing to bestow upon him the sacred honor of being her toilet mouth.
Slowly, she lowered her delicately sculpted derriere over the small of his back, her thong-clad sex rubbing against his bare skin. She released a sigh of contentment as she opened her legs wider, offering easier access to her awaiting toilet slave.
"Today is a special day for you, my little toilet slave," she purred, her breath warm against his ear. "You have worked so hard to earn this title, and today you will finally prove yourself worthy."
The toilet slave felt a burst of pride swell within him at her words, but it was quickly replaced by the overwhelming desire to please his Mistress. He extended his tongue and pressed it against the rim of the toilet bowl, priming himself for her gift.
Without further warning, Mistress Michelle lifted her skirt higher, revealing her plump, pink anus. She groaned in delight as she released a torrent of urine into the toilet bowl, the warm liquid splashing against his face and neck. He lapped it up gratefully, his tongue darting in and out of the stream of golden liquid.
As the urine slowed to a trickle, he felt her weight shift slightly. He knew what was coming next and braced himself. With a powerful surge of her abdomen muscles, Mistress Michelle expelled a massive turd into the waiting toilet. It was the size of a small child's fist, covered in mucus and stained with her fecal matter.
The toilet slave hesitated for a moment, but then stretched his mouth as wide as he could and opened his lips wide. The putrid stench of ass and excrement assailed his senses, but he continued to extend his tongue, welcoming the filth into his mouth.
With a tentative movement, he slowly pushed the log of shit towards the back of his throat. He gagged and choked as it slid past his lips, but he refused to give up. He kept pushing until the entire mass was wedged firmly in his mouth, filling every corner of his mouth with her feces.
As he lay there, his mouth full of Mistress Michelle's shit, he felt a sense of achievement wash over him. He had finally earned the title of her toilet mouth, and nothing else mattered. He would gladly spend the rest of his life devoted to her, cleaning up her waste, and savoring the delicious filth in her every deposit.
