When was the worst you ever had to pee? And did you make it in time?

Well, it's Tuesday night and I'm super bored, so why not ask a random question? I'll tell my story. In Grade 7 (middle school, I was 13 years old) we went on a two night trip to a nature reserve. On one of the days we went on a long hike in the forest from morning to sundown, where we did activities like starting a fire and building shelter. Anyway, we were given the chance to use the washroom just after lunch, after which we wouldn't get a chance to until we got back to the dorms for the evening. Me, being the stupid girl that I was, decided not to go even though it was super hot out and I had been drinking loads of water. By 4 o'clock I was bursting, and I couldn't exactly squat in front of everyone, so I was forced to hold it. I never rushed to a washroom so fast in my life, and I'm ashamed to say that I didn't entirely make it. Luckily it was only a few spurts in my panties and didn't show much. What's your story?
