Stroking in the Safeway parking lot

I was stroking in the Safeway parking lot. People kept walking by and I don't think anyone noticed me jerking it. Then a women was staring at me, I think see could see that I was pumping on it. I motioned her over to the car. She came to the car staring a my hard cock. I asked her if she would like to see it cum. She said YES so I shot a big load all over myself. She said 'that was nice' and walked away.
