i was in a mandatory lecture for over an hour while i was absolutely bursting to piss. i already had to go before what was supposed to be just a 30 minute presentation began and the pressure kept increasing as i watched the minutes go by. the tight spandex leggings rubbed against my clit which relieved some pressure but eventually i couldn't bear it anymore and had to stand up. i used all my muscles dancing around, my poor bladder engorged and pushed to the limit. i needed to go to the bathroom before i had a full blown accident! after what seemed like a lifetime, the lecture ended. i finally made it to the bathroom! i teased myself over the toilet seat in my pale undies, and a strong burst of pee made it through and soaked my panties. it was only moments before i exploded. i gushed for nearly a minute! please enjoy!
