Fat girl desperate to pee outdoor wet her panties outdoor and smoke until they dry

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 by peeing outdoors. I was outdoors relaxing in this hot sun and prospecting a house under construction. Since I had to wait for the agent to arrive I lighted a cigarette and enjoyed the sun, until I felt my bladder ready to explode. I just lifted my mini skirt and pee standing up. I got my panties wet so I just stayed there with my legs opened until my panties dried, smoking and waiting for the real estate agent.
