I [F]24, caught a guy jerking off in his car. Offered help, but something unexpected happened.

This happened fairly recently. I was going back to my car through an underground parking lot after grocery shopping.

As I got to my car there was an SUV parked next to me and I noticed some movement. There was a man stretching his T-shirt over his crotch and as I glanced through the window he lifted the shirt uncovering his boner.

He clearly did that on purpose. It was actually only the second time in my life I've encountered a dick flasher.

Now I had two choices - ignore it or have some fun.....I chose the latter. Could not help myself haha.

For a moment I just looked at him jerking off through the window. I could see he had realized I'm watching, he started jerking off even faster with a happy, but at the same time scared look on his face.

I quietly knocked on the window, he got startled and looked over, and I gave him the sign to roll down the window.

The look on his face was hilarious, it was a battle of emotions between "Omg, I've won the lottery" and "Omg, I'm in so much trouble".

He timidly rolled down the window. I looked him in the eye and with a big smirk on my face and whispered: "Let me help you with that", and pushed my tongue in my cheek making a blowjob motion.

As soon as I said that, I suddenly noticed something white landing on his chest. I looked down and the dude was having a full blown orgasm. He let go of his dick, quickly started the car and drove off while his dick was still shooting cum.

In that moment I just started laughing out of shock. It was so unexpected, made me feel like a Jedi haha.
