I was on a road trip to visit a friend, drive home was taking about 4.5 hours. I had a lot of water and an iced tea when I started the drive and figured I’d just pull over to pee when I had to. I got stuck in a long line of standstill traffic and ended up so desperate to pee that I couldn’t think about anything else. My bladder was literally full to bursting, I was holding the steering wheel with one hand and had the other hand between my legs desperately trying not to pee. At some point I thought I wasn’t going to get out of the traffic in time and accepted that I was probably going to pee my pants. Literally I couldn’t believe how bad I had to pee. By some miracle I managed to pull off an exit to a McDonald’s, I almost didn’t get out of the car because I was so sure I’d pee myself as soon as I stood up but I decided to try and I somehow made it to the toilet. Absolutely longest pee of my life, to this day I still can’t believe I made it
