As Lady Crocodile, the dominant alien princess, strolled through her luxurious space station, she spotted the meek human slave she'd chosen for today's unusual activities standing nervously by the water tank. She chuckled to herself, amused by his obedience thus far. "It is time for the call of nature, slave Bodo," she commanded, her golden eyes glinting with both authority and mischief.
Bodo, the human male, trembled in his restraints as he was led to the massive toilet bowl in the center of the room. The contraption looked more like an industrial vat than anything else, with controls and levers adorning its sides. "You may call upon me when you are ready, slave," Lady Crocodile purred from her perch on top of a high ledge overlooking the chamber.
With a deep breath, Bodo complied, releasing his bladder into the steely bowl with a loud hiss. The warm sensation spread through his body as he watched helplessly as she leaned forward, her long tail dangling playfully in front of her. "That's it, slave," she cooed, her scaly green skin reflecting the light from the chamber. "I believe it's time for you to empty out your colon as well."
Bodo felt his face turn bright red with embarrassment but knew better than to disobey his mistress. He grunted, pushing out a large turd into the waiting water with audible relief. It floated lazily beside the smaller puddle of urine he'd already produced.
Lady Crocodile watched with amusement as he struggled to maintain his composure. "It appears you have made quite a mess, slave," she noted, her grin widening. "Allow me to assist you." She slithered down from her perch, revealing a sleek, serpentine tail that curled around his waist before vanishing beneath him.
With a wiry strength, she dragged him across the slick floor towards the tank, his dirty undergarments clinging to his legs. She reappeared with several tools, including a long metal scraper. "It's time for you to clean up your mess, slave," she purred, fondling one of the nastier-looking implements.
Bodo felt a shiver of fear and anticipation run down his spine as she directed him to take the tools between his trembling fingers. "Yes, my Lady," he whispered, his voice barely above a whisper.
As he cleaned the toilet bowl, mirroring Lady Crocodile's movements with shaking hands, she watched on, her eyes gleaming. "You do make an adorable little worker bee, don't you?" she mused, running a clawed finger down his cheek. "I think I'll keep you around for a while."
With a satisfied hum, Lady Crocodile leaned back against the tank, her immense weight causing the metal to groan under the strain. "Now, slave," she purred, "you may rinse yourself off and return to your duties." She pointed towards a small hatch in the wall, from which steam issuing forth in soft wisps.
Bodo, his face flushed with both shame and arousal, did as he was told, stepping into the sauna-like chamber to wash away the remnants of their bizarre encounter. As the warm water washed over his body, he couldn't help but wonder what other twisted tasks Lady Crocodile might have planned for him in their next session together.
