Erica smiled softly as she closed the bathroom door behind her, leaving her husband alone in the living room. She was grateful for the privacy as she sat down on the toilet, her slender frame sinking into the cold porcelain seat. Today had been a rough one, and she couldn't wait to finally release the weight that had been pressing down on her all day.
Her husband had no idea about her little secret hobby. While he thought she spent her evenings baking cupcakes, the reality couldn't be further from the truth. Every morning, Erica woke up early and sat on the toilet seat, her tight little asshole clenching around the hard lump inside of her. She'd spend a few minutes pushing and prodding, coaxing all of her poop out of her bowels and onto the cold ceramic.
Once she was done, she'd carefully clean herself up, making sure not to leave any traces of her morning routine behind. Then, she'd spend hours meticulously crafting the most beautiful cupcakes she could imagine, using only the freshest ingredients money could buy. But when her husband came home from work, he'd always get a special treat - a cupcake made from her very own shit.
She couldn't help but chuckle to herself as she imagined his face when he took the first bite. It was a mixture of horror and disgust, but also a strange kind of curiosity. He'd never suspect that it was his own wife who was feeding him the feces-filled pastries, and that made the whole thing even more delicious.
Her ass tightened again as another wave of nausea washed over her. She began to push again, relishing the warmth spreading through her abdomen as another log slid out of her. She didn't mind the mess or the smell; it was all part of the process. And when she was done, she'd take a long, hot shower to wash away any evidence of her secret life.
Her husband was going to love tonight's cupcakes. With a soft sigh of satisfaction, Erica stood up and flushed the toilet, watching as her morning's work disappeared down the drain. It was a small price to pay for the twisted little thrill she got from feeding her husband his own shit.
