Coming home from work late last Saturday and pulled over to a lay-by

I was travelling from work to home late last Saturday night about 10:00pm, and pulled into a lay-by to answer a call from a colleague at work and was met by quite a few cars already parked up. Whilst I was on the phone I saw a guy go over to another car and opened their door. The next thing I’m watching him get fully sucked off and then banged against the car. I got so wet I had to get myself off there and then. I think it was near Hartford. A lot of trees around. Anyone help if it’s really good. If only they knew I was rubbing off ha. 10 mins and then I left
