Fat woman desperate to pee, empties her full bladder - She doesn't have where to pee but on this excavator bucket

We went for a ride outdoors. She had a lot of juice to quench her thirst. She has a big bladder (being a big girl) but it gets full and she needs to empty it peeing outdoor. We had to pull over because she had so many liquids that she cannot held herself. She climbs on a excavator bucket and she opens her legs and pee trough her pants right there being very scared to be seen by cars and people passing by. Yet she still manages to relive herself on the excavator bucket in a tight pee jet. This fat girl with huge tits have a big bladder. She went outdoors to run and try to loose some weight. But since it is hot she had a lot of beers. Since she is on a dirt road and she is not very close to a house or other men, she just let herself go and pee in her tights big volume of pee wetting her tights from top to bottom.
