Panty pooping girl

My name is Emma and I like to poo my knickers on purpose.

I held my poo all weekend and my mum took me shopping on Sunday. While we were at the supermarket I started getting really desperate and I told my mum I was going to the toilet and she told me to meet her at the car because she knew I would take a while.

When I got to the toilets I found they were closed due to a flood and the disabled toilet was locked so I had to wait until I got home. When I got to the car my mum was still shopping because I'd only been gone for a couple of minutes. I waited by the car hopping and fidgeting as I tried desperately not to poo myself and when my mum eventually got to the car with a trolley full of shopping she knew I was about to have an accident and she asked me why I hadn't been to the toilet. I explained that they were out of order and she told me pulled the blanket on the back seat under me in case I wet myself in the car and I told her I needed more than just a wee. She said fine but if I was going to mess myself I would have to open the window. I folded the blanket into four while my mum loaded the boot and I sat down on the blanket. When we were ready to leave she asked me if could wait until we got home and I told her I wasn't sure if I could. She then told me if it was going to happen I should get it over with now because the traffic going home was bad and it might take a while to get home. I felt embarrassed and excited at being allowed to use my underwear as a toilet and I felt my face burning red as I opened the window. My mum put her hand on my thigh and she admitted that she'd pood herself in the car a few months ago after she dropped me off at school. She said there was nothing to be ashamed about having an accident and I wouldn't be the first or the last person to go in her pants. I relaxed and quickly filled my knickers and I wet myself as well. The relief of it was so good I let out a sigh and my mum asked me if I felt better. I told her what do you think! When we got home I went straight to the toilet while my mum took the shopping in and I clenched myself up and changed my knickers and went downstairs to help her put the shopping away. She promised not to tell anyone about what happened and I found the whole experience very arousing and I had to go to my room to pleasure myself.
