I just arrived at a secluded place and I change in the car putting on my new jeans tights. But.. I made a mistake. I forgot to pee when I left home so.. jumping up and down for my exercises makes me want to pee, but.. I just sit on the cement block and pee right there hoping no one passing by would see me. But since I wet myself so well I have to change. My luck I have a spare pair of panties. I was outdoor 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.
