I Had A Real Accident In My Pants

I was hurrying across a local car park to get to the toilets but when I got to the toilet door there was a sign on it saying closed for cleaning. The door was locked so I waited a few minutes until I was very desperate. I banged on the door and no one came but I new there was someone there. By this time there was another person waiting. He could see I was uncomfortable and banged on the door again. By then I felt so desperate I actually peed myself, and tried not to do anything else. But desperation won and I messed my pants in front of a complete stranger just as the door was unlocked. I waffles up to a cubicle and began to change my pants. They were to dirty to reuse and I had telltail stains on my shorts, eventually I tied my fleece round my waste and went home.
