Dahlia lay under the rimming stool, her body arched in anticipation. She had been trained to be nothing more than a mouth and anus for her Master's pleasure. Today, she was there to receive his shit.
The stench of his piss filled her nostrils as she felt his warm stream cascading over her body. It was a sign that he was about to reward her with her favorite treat. As his piss slowly seeped into her skin, her mind wandered back to the first time she'd ever taken a human's waste into her mouth.
At first, it was revolting. The taste, the texture, everything about it repulsed her. But as she learned to please her Master, she also learned to numb her senses and crave the bitter flavor of his shit. Now, she couldn't imagine wanting anything else.
Suddenly, she felt his cockhead at her entrance. She spread her asscheeks wider to accommodate him, her anus already slick with anticipation. The moment his hot flesh penetrated her, she let out a moan of pleasure. It was a dirty, forbidden act that filled her with shame and arousal in equal measure.
As he fucked her anus, she relished in the feeling of being used. His shit slid down her throat, coating her tongue and teeth with its putrid taste. Each time he withdrew from her anus, she knew it was only a matter of time before he filled her mouth again.
After what felt like an eternity, he pulled out of her and let her taste the foul bouquet of his combined piss and shit. She lapped at it greedily, savoring every last drop.
"Good girl," he murmured, his voice thick with satisfaction. "You're such a filthy, disgusting whore."
The insults only fueled her arousal. She loved being called names, loved being treated like a piece of shit. Because in his eyes, that's all she was.
As he prepared to fill her mouth again, she looked up at him with pleading eyes. This was all she could give him, all she was good for. And she would do it a thousand times over if it meant keeping him happy.
