I had my first experience of CFNM, when my fantasies of CFNM were only just starting. From memory, it was through meetme (my yearbook originally). I was around 24, and she was in her late 40s/early 50s, and what got us talking originally was her enjoyment from CFNM, specifically being fully dressed while a man was fully naked, knowing that she had an immediate power in this situation.
We had agreed to meet up in a carpark during the day overlooking the coastline, and were going to find a quiet spot for us to partake in this scenario, but that all she wanted was the power scenario of us talking out in the open, while I was completely naked. I was very excited by this!
Being typical England, when we finally met on the pre-arranged day, the weather played havoc on our plans, and sitting together outside was not going to be a comfortable option for either of us, so she suggested that she come over to my car and sit in the passenger seat (we had both driven there separately). Small talk ensued, and my nerves were kicking in which I'm sure she could tell. She decided to assume her soon-to-be role of the one in power, and demanded that I took every single article of clothing off, hand them to her, and then open the car boot for her to lock all of my clothes in before getting back into the car and push my seat back as far as it would go, and the seat back as flat as possible.
Back in the front seat, her gaze all over my body had an immediate effect on me, and i got very hard very quickly. This seemed to amuse her, but she chastised me for not being able to control myself.
