As the night wore on, Ken felt a gnawing discomfort in his stomach. He had indulged in a delicious meal with his gorgeous ScatBarbie, but something wasn't quite right. He excused himself to use the restroom and locked the door behind him.
He felt his bowels loosen as he sat down on the toilet, and before he could even react, hot, steaming shit poured out of him. It was like a never-ending stream of warmth and relaxation spreading through his body. He was completely overwhelmed by the sensation of releasing such an enormous amount of feces.
Ken kept emptying his bowels for what felt like hours, his cheeks flushed with embarrassment but also filled with excitement. He couldn't believe how good he felt, allowing himself to become this disgusting waste disposal unit for ScatBarbie's pleasure.
Finally, when the pain in his full bladder became unbearable, he stood up and let out a huge stream of pee, mixed with a little more feces that he had yet to release. He knew there was no way he could present himself to ScatBarbie now, covered in his own filth.
He carefully cleaned himself up using some toilet paper, but his arousal hadn't subsided. He wanted her to see him this way, to taste his own feces and know that he had fully embraced his role as her toilet slave.
As he presented himself to ScatBarbie, proudly displaying his diligently cleaned shit-covered asshole, she could see the desire in his eyes. She ran her tongue over her lips, salivating at the thought of tasting his shit.
"Perfect," she said, her voice filled with lust. She positioned Ken's ass over her mouth and nose, allowing him to feel the warmth of her breath on his anus. "Drink up, my disgusting toilet slave. It's time for you to taste your own shit."
Ken moaned as he felt her tongue pushing against his asshole, slowly working its way inside him. He watched in a mixture of horror and arousal as ScatBarbie began to pull out his shit, chewing it before slowly pushing it back into his rectum.
"That's it, darling. Let me be your Goddess, your shitting mistress," she whispered seductively. Ken could feel her wet, warm mouth working him, pushing his walls in and out with each thrust of her tongue. He felt himself about to cum again, his cock throbbing with arousal.
"Say it, Ken," ScatBarbie said, her voice low and commanding. "Tell me how much you love being my shitting toilet slave."
Ken groaned as he started to speak the words he never thought he would utter. "I'm your shit-covered toilet slave," he moaned. "I love it when you make me eat my own shit." He felt his cock erupt once again, shooting his hot cum deep inside ScatBarbie's mouth, tasting the sweet mix of his shit and her saliva on his tongue.
Together they collapsed onto the floor, spent and satisfied. Ken looked up into ScatBarbie's eyes, feeling a sense of belonging and love wash over him. He knew that from now on, he would gladly be her shit toilet slave, dedicated to satisfying her every desire, no matter how depraved or taboo.
