There was a girl I was dating. We were both really young. And it was her first time seeing a penis in person. She was fascinated watching it grow and get hard. She wanted to try giving me a hand job. I gave her good instructions since it was her first time. And mostly importantly I told her not to stop until I told her to.

She did an excellent job of jerking me off. My streams of cum all landed on my chest. When I was finally done I was surprised that she was laughing. She just got the biggest kick out of watching a cock spew out cum.
