Mistress Mystique - Preggo Gotta Go!

On this fateful day, Mistress Mystique summoned her devoted slave to her lavish chambers. She was in a playful mood, knowing the sense of anticipation it would cause in him. Dressed in nothing but a skimpy black lingerie that hugged her pregnant belly tightly, she smirked as she approached the golden throne that was her toilet seat.

Looking at him with her piercing eyes, she commanded, "Preggo gotta go! Undress me, then prepare yourself. You are about to experience the ultimate honor of serving your Mistress on her throne."

The slave could barely contain his excitement as he began removing her clothing, his hands trembling with anticipation. With each article of clothing removed, Mistress Mystique's body became more exposed - her full breasts jiggling with every move she made, her swollen belly glistening in the dim light.

Finally, she was completely naked before him. She climbed onto her throne, revealing the beautifully crafted opening for her slave to perform his duty. Without further instruction, he knelt before her and lowered his head, his mouth watering at the thought of tasting his Mistress's nectar for the first time.

Mistress Mystique leaned forward, giving him easy access to her tempting opening. She purred with delight as he hesitantly began to probe his tongue inside her, exploring every inch of her wet, warm depths. She moaned in approval when he found the right rhythm, his tongue dancing in sync with her desires.

As he began to feel more comfortable with his new role, he found himself growing harder and harder, his cock throbbing painfully against his own belly. Mistress Mystique noticed his discomfort and smirked. "Don't worry, slave," she said softly. "Your needs come second to mine. Relax and enjoy serving your Mistress on this most sacred of occasions."

With that, she began to release - waves of hot liquid flowing over his tongue and down his throat. He couldn't believe the taste of his Mistress's piss, let alone the incredible feeling of having her load himself up with it. As she emptied herself onto him, he felt a sense of euphoria wash over him, knowing that he had finally earned her trust and devotion.

When she was finally done, she sat back on her throne, looking down at her satisfied slave with a satisfied smile. "You did well, my toilet slave," she purred. "Now, clean yourself up and prepare for the next round. Preggo gotta go, remember?"

The slave couldn't believe what had just happened, but he knew that he would do anything to please his Mistress. He stood up, his erection still standing at attention, and began to clean himself up. As he did so, he felt a new sense of pride and belonging wash over him, knowing that he was now an integral part of Mistress Mystique's toilet slavery world.
