As for the OP, I have 2 as well.
1. With SO, we were driving and she puts her hand down my pants and gives me a hand job at 65 mph. BTW, she was driving
2. I was on my second date with this one girl. We hit it off well on the first date, so I knew the second date would be a hell of a time. This girl had a body that wouldn't quit, and we were experimenting with different positions-- pure porn type date. What made it memorable was when I was going down on her. About five minutes into eating her out, she grabs my head by the hair and just pushes me into her pussy. She kept screaming not to stop. A few minutes later, she has this earth shaking orgasm that lasted what seemed like 2 minutes.
