Serene stood transfixed as her stepmother's massive turd slid out of her ass and onto her chest. The woman had no intention of stopping and to her horror, another and another. Serene had never seen so much shit in her life. The weight of it was immense, covering her completely. It felt warm against her skin, and the smell was overpowering. She tried desperately to breathe through her mouth, but it seemed like it made no difference.
As if that wasn't enough, her stepmother grabbed a handful of Serene's hair and pulled her head towards her crotch. She groaned as she felt the elder woman's piss hitting her face, the smell of urine mixing with the feces on her body. She couldn't move, couldn't speak, couldn't do anything but endure this humiliating assault.
Finally, it seemed like there was no more coming out. Her stepmother stood up, towering over Serene who was still bound to the toilet. She stared down at the girl, panting heavily from the exertion. Serene waited for what felt like an eternity before her stepmother finally spoke.
"Well, it seems like you've had your fill of my shit. Now it's time for me to have some fun." She grinned wickedly as she reached down, grabbed a handful of Serene's hair and slammed her face into the pile of feces on her chest.
Serene gagged as the shit hit the back of her throat. Her eyes watered and she thrashed in her bonds, trying to escape the disgusting onslaught. Her stepmother just laughed, pulling her away and plastering the shit on her face repeatedly, forcing her to eat and swallow every bit of it.
Soon, she had smeared the shit all over Serene's body, covering her from head to toe. Then, she bound Serene's mouth with duct tape, gagging her to prevent any further sounds of protest. With one last grin, she whipped her panties off and stuffed them into her mouth before shoving one of her own feces into her mouth.
"Swallow that, slave," she commanded, holding Serene's head still as she forced the girl to chew and swallow the shit. Serene choked and gagged, tears streaming down her face as she tasted the foulness that coated her tongue. She wanted to throw up, but she couldn't move, couldn't escape.
Her stepmother didn't stop there. She grabbed part of the shit on her stomach and smeared it across her face, laughing as Serene's eyes bulged in horror. Then, she grabbed a handful of the girl's hair and dragged her face into her crotch, making Serene taste her own piss mixed with her shit.
Finally, her stepmother stood up, satisfied with her work. Serene lay there, covered in filth, unable to believe what had just happened. She felt like a used up toilet itself, dirty and used in every way imaginable. She could only hope that someone would find her before her stepmother returned to finish what she had started.
