Mandy's diary 4

I went for a walk in the park today and naturally I was desperate for a poo. There were a lot of people around being the school holidays and I didn't particularly want to be seen pooing myself so I decided to use the public toilets by the lake. It was quite a long walk and as I got closer I saw a couple teenage girls walking up to the door. I prayed none of them was having a poo because there's only one cubicle and I was afraid I would poo myself if I had to wait too long. The girls looked really desperate and I they were arguing about who should get to use the toilet first. One of them was holding her bum and my heart sank because I knew I might have to wait a while. The other girl was trying to pull her away from the door but then she grabbed her bum as well. The first girl got to the door and pushed it but it didn't open. She pulled it but it was locked. The second girl was squatting slightly and I knew she was pooing herself and I was tempted to do it in my knickers but I didn't want to it to look like I was doing it on purpose. Then the first girl went bright red and admitted she was having an accident as well. I watched intently as the two girls pood and wet themselves and I thought what the heck and started going in my knickers too. It felt so good to be able to poo myself in front of two girls without being embarrassed as we were all in the same situation.
