Bratty Panther stood in front of the full-length mirror, admiring her reflection while she wore a pair of white, flimsy plastic panties. Despite the bedroom's door being closed and locked, she knew that someone was standing on the other side, watching her every move. She loved it.
She could feel the warmth spreading between her legs, signaling to her that she had to go soon. With a devious grin, Bratty grabbed the hem of her dress and lifted it up, revealing the full view of her plastic panties underneath. The fabric was incredibly thin, almost transparent, allowing anyone who looked to see the outline of her bare ass cheeks through it.
Bratty unbuttoned her pants and lowered her zipper slowly, watching herself in the mirror as she did so. Her heart raced with excitement at the thought of what was about to happen. She slipped her hand inside her panties and began to play with herself, her other hand still holding onto the hem of her dress.
As her body started to shake with pleasure, Bratty felt the urge to poop becoming almost unbearable. She bit her lip in anticipation and closed her eyes, trying to concentrate on the sensation. With a satisfied moan, she finally let go, releasing a long, hot load of shit into her plastic panties.
She didn't move for a while, just stood there enjoying the feeling of relief. Then, slowly, she began to tease herself and her audience, lifting the hem of her dress higher and rocking her hips from side to side. She could imagine the person on the other side of the door, desperate to see more but unable to do anything about it.
Finally, satisfied with the teasing, Bratty pushed the pile of shit down and grabbed a wad of toilet paper. She wiped herself clean and pulled her panties back up, adjusting them so they were just right. She took a deep breath, then turned to face the door. "Well?" she asked, raising an eyebrow. "Aren't you going to come in and see what kind of mess I've made?"
