As Mistress Mystique sat on her white slave's face, she couldn't help but feel a rush of power coursing through her veins. She loved having this pathetic little cretin at her beck and call, ready and willing to serve her every need. Tonight, however, she had something special planned for him.
"You are mine to command, slave," she purred, leaning down slightly to run her tongue along his earlobe. "And tonight, I want you to take my shit."
The slave, clad only in a collar and a look of utter humiliation on his face, nodded obediently. It was their final night together, and Mistress Mystique intended to make it one he wouldn't soon forget.
"Thank you, Mistress," he whispered, his voice shaking with fear and excitement.
Mistress Mystique stood up, her perfect ass still within sight of the slave as she walked over to the bedroom door. She could feel his eyes drinking in her every move as she knelt down before him once again.
"Let's see if you're worthy of taking my load," she said, her voice containing just a hint of menace.
With that, she lowered her delicate bare buttocks towards the slave's face, swaying her hips lewdly as she teased him. The slave couldn't believe his luck; after days of servicing his Mistress in every other way imaginable, he was finally going to taste her ass!
Mistress Mystique grinned as she felt his warm breath on her anus, and without further warning, she released a torrent of feces onto the slave's face. He tried his best not to flinch as the hot, sticky mess coated his skin, but he couldn't help himself.
"Mmm, that's it," Mistress Mystique purred, running her fingers through his hair. "You're going to clean my asshole now, aren't you?"
The slave nodded fervently, reaching up to take her ass in his hands. She loved the way he worshipped her, the way he couldn't get enough of being close to her ass. As he gently licked and cleaned her anus, teasing him all the while, Mistress Mystique felt a sense of satisfaction wash over her.
"That's a good little toilet," she murmured, letting her fingertips drift down to tease his cock. "Now let's see if we can't get you off too."
With that, she leaned forward, taking his semi-hard cock into her mouth and starting to work her magic once more. The slave's head thrashed back and forth as he felt her hot tongue on his cock, his ass still exposed for her pleasure.
"MMM," Mistress Mystique moaned, her eyes rolled back in her head as she took him deep into her throat.
It wasn't long before the slave was shuddering in orgasm, his cum filling her mouth as she continued to work him over. Once he had finished, she stood up, her ass still glistening with his saliva.
"And that, my little toilet," she said with a wicked grin, "is how you please your mistress."
With that, she turned and walked away, leaving the slave to clean himself up and reflect on the incredible weekend they had just shared. As for Mistress Mystique, she was already thinking about the next poor soul she would capture and use for her own perverted pleasures.
