I was quite desperate while out one night, wearing a suit. I stopped to water the trunk of a tree on the street. A woman was walking her dog on the other side of the street, but crossed all the way over to the side I was on. I pretended not to notice, but turned to give her a better view, pulling back my foreskin to reveal the head. I felt myself getting harder as her eyes were on it. She smiled and looked me in the eye, and continued walking without saying anything.
