A few months ago I got caught up in a motorway tail back and a stand still situation. Sat in my car about 25-30 mins waiting going nowhere I was needing to have a pee.. Others were out of their cars walking about, looking down the lines if stationary traffic. I got out to see if it would help alleviate my need.. Walking about my car it just got worse... I was trying to think what I should do. The guy who was infront came over to say hello and then seen my discomfort and asked what's wrong.. embarrassed, I told him. He said its easy.. open both doors on the nearside of your car, it will give you privacy, andget between then. He told me that he would stand with back to me and be on guard. It sounded good and I was desperate. So I opened both doors and yes it looked good. He stood a few feet away with his back to me so I pushed down my panties, lifted my skirt and got in a semi comfortable position. I slowly started to pee and as I did he turned around..staring between my legs watching me. I wanted to stop but I couldn't.. he just unashamedly continued to look at my pussy as I semi squatted there. Watching me pee. After about a minute I stopped.. a few more short blasts and i was about to stand and cover up. As I pulled up my panties he thanked me for the amazing show and then said a had a lovely pussy.. shame he couldn't see more. About 10mins after that the traffic started to move in the distance...
