Jogging bottoms

Has been doing some diy and needed some gear, headed to the store in my work gear, old t shirt and old black jogging bottoms with steel toe cap boots. Got my stuff and headed home, as I was going out that evening I decided to get diesel on the way back to save time after. I needed to get back as I was already needing the loo after waiting in line at the DIY store. The garage had a problem with their card machine so there was a queue to pay, a lady had been in and asked if they had a toilet for her son and was told it had been vandalised so was shut, he looked as desperate as I felt. I was doing my best to be discreet in my hour of need and the grumpy customer going on and on wasn’t helping. I had no cash so was waiting for the card machine to be sorted. At one point I sneezed and peed a bit before getting it under control. A casual look and the joggers looked ok. The lady, two people in front seemed to be in the same position by the way she was swaying. Eventually they managed to get it sorted, the supervisor cursing as he walked off leaving the poor young woman to cope then with the irate queue. As I was getting closer I could feel the sweat pouring out and was worried that would not be the only thing, the machine went off again just before I got my turn. Supervisors called, lots of cussing and I could feel the pressure growing, I tried grabbing myself through my pocket which worked until I was shocked out of my own world by the girl saying “sir, what pump” I had forgotten, looked out the window for the pump and it happened, I spurted into my boxers which held for a few seconds before trickling down my leg. I pushed myself against the counter which only served to increase the sensation. She looked at me strangely saying you ok luv, I stuttered yes tapped my card, the approval seemed to take ages, then headed for the door past the queue, I could feel the heat in my face and the pee now flowing down both legs. As I walked to the car I could hear the sloshing of my boots with every step. I opened the door and as I got in I looked back and could see a staggered line of pee in my footsteps. To make it worse the woman behind me in the queue had left the shop and was smiling at me as she walked to her car. I sat there for a minute emptying the last of my bladder whilst shaking from embarrassment but also a sense of naughty excitement. I looked down at the wreckage and apart from the shiny crotch the wet legs didn’t show too badly. I drove home and had to attend to something before cleaning the car seat.
