Often, I once got caught by 2 older ladies. I was actually wearing a wristwatch on my dick. No just jacking off. When the ladies drove past, the car stopped and backed up. They took a good look and told me it looked nice. They were really friendly.
My ladyfreind went with me to an adult box store in Monterey, CA. We went into one of the booths and she gave me head while people watched through the holes in the wall. I came in her mouth twice while she sucked me with two hands.
I once was leaving a liquor store after looking at some porn. I saw a lady sitting in her car that I recognized from the Oaktree Lounge. I walked up to her car and unzipped my pants.....it landed on the car door with a thud. I'll never forget the look on her face. She was beautiful. It seemed like I had my dick out forever, but it was only a few seconds. My dick was so hard it hurt. I went back to the car and let myself out of misery. I saw the lady a few weeks later at the lounge. I was with my ladyfriend, so we just smiled at each other.
I've met a few women that will use their elbow initially to find out the size. While sitting on a couch kissing it's pretty easy to just let the elbow graze the dick, and then comes the hand.....mouth. Other women find out through word of mouth.
I once walked up to a car that was parked next to my house, a woman was giving head to a man. I had my dick out and just stood there until the woman stopped and looked down at my dick. She was smiling, but the guy was pissed. He put the car in gear as I masturbated to his smiling woman.
