Grocery Store Incident

so earlier today i was at the grocery store, just minding my business, picking out my groceries, when the urge to pee hit me like a truck out of nowhere. I tried to stop it with everything i had, but no luck. Normally my pullup would come in clutch and save me in situations like this, but i had already wet it 3 times today and i knew it would never handle another wetting. It was too late, however and i started flooding my pullup. I stayed frozen in place, not letting anyone see, as i felt that familiar warm feeling at the front of my pants. I hoped it would stop soon, but (as usual) i was wrong. I looked down and it was worse than i thought. the front of my pants were completely soaked, and it ran all the way down my legs and created a big piss puddle on the floor. At this point everyone was looking at me and i was really embarrased. I made my way to the cashier to check out, because i still needed those groceries. Honestly the most awkward check out expierence of my life. After i was done, i RAN back to my car, and apparently i wasnt done, because on the 20 min drive home i peed again, soaking my car seat even further.
