There once was a plump woman named Sarah who worked as an nurse at a busy hospital. She was devoted to her job and loved helping people, but she had a secret fantasy that she hardly ever shared with anyone. Sarah was fascinated by the idea of engaging in scat play, which involved defecating or urinating during sexual activities.
One day, while taking a break from her shift, Sarah found herself alone in the staff toilet. The room was empty and quiet, and the urge to defecate was overwhelming. She lowered her panties, revealing her puffy, hairy rectum, and began to push. After a few moments of struggling, she managed to release a large, soft turd onto the cold floor of the toilet cubicle.
As she sat there, feeling the warm, strange sensation of her own feces between her fingers, Sarah couldn't help but feel an intense wave of pleasure wash over her. She began to scratch her anus, moaning softly as the feeling spread through her body.
Just as she was about to masturbate herself with her feces, she heard someone else enter the toilet. A young man, one of her colleagues, walked in and saw her. At first, he was startled, but then he couldn't help but be drawn in by the erotic scene before him.
Without saying a word, the man walked over to Sarah and knelt down next to her. He gently reached out and caressed her stomach, running his fingers through the soft, plump folds of her body. Then, he leaned in close and whispered in her ear, "Would you like me to help you play with that?"
Sarah didn't hesitate for a moment. She nodded eagerly, and the man slowly began to lower his own pants. His cock sprang up, thick and hard, and Sarah couldn't believe her eyes. She had never seen such a large cock before, and the thought of taking it inside her made her shudder with anticipation.
The man positioned himself behind Sarah and guided his cock towards her asshole. With a soft moan, she felt the head of his cock press against her anus, breaking the surface of her skin. He pushed gently at first, and then harder, and suddenly she felt him penetrate her completely.
Sarah cried out in pleasure as she felt herself being filled up by her colleague's enormous cock. She reached back, feeling for his hands, and together they began to move in a rhythmic pattern, fucking each other on the cold, hard floor of the toilet cubicle.
As their passion reached a fever pitch, Sarah reached down and grabbed a handful of her own shit, smearing it over her body. She felt the coarse, crumbly texture against her skin, and the intense mix of pleasure and humiliation sent her over the edge.
With one final push, Sarah felt herself cum hard, the walls of her pussy clamping down tightly on her colleague's cock. As she came down from her high, she looked up to see him grinning at her, covered in sweat and cum and their combined mess of feces.
"I never knew," he said quietly, pulling out of her and helping her to her feet, "that you were into that kind of thing."
Sarah blushed, but she couldn't deny the thrill she'd felt. "I never thought I would do it with someone else," she admitted, "but it was amazing."
And with that, the two of them left the toilet together, their hearts racing and their minds reeling from the intensity of their scat encounter.
