Big thanks to LittleJohn for posting this story on the Cfnm Forum which is where you’ll find the full version, here’s a taster of his experience – it’s well worth checking out the full account 
‘I was dating a rather sexually adventurous woman who was by no means shy. One day at her place she mentioned she really enjoyed seeing me naked and would I stay naked for her at her place. I agreed and often we’d be on the couch, she dressed, me not, making out and petting. She got turned on and used the CFNM scenario as a type of foreplay.
One afternoon we were swimming in her pool. We threw our sits onto the side and did the skinny dipping thing for a while. At dusk she mentioned there was a hot porn movie she wanted to share with me and hopped out of the pool wrapping herself in a big towel while grabbing my suit and towel and ran up the 30 stairs from the pool to her deck.
“C’mon,” she said, waving the suit at me, “don’t get shy on me now.” So I ran up the steps stark naked in full view of the neighbors on either side (if they had been watching). Only later did I find out that had been a prearranged signal.
Back in her TV room we were on the sofa, me naked and she in her sun dress next to me. The movie was pretty hot and was getting me hard. The kissing and her rubbing my cock was helping in the erection department too. She rested her head on my shoulder while she idly played with my dick and watched the movie. Suddenly she pulled away and said, “Oh, I got some of that beer you like. Why don’t you go get us some.”
I knew she just wanted to watch me walk with a hard on so I smiled and stood then headed upstairs, taking them 2 at a time. Top of the stairs I turned right into the kitchen and stopped dead in my tracks. There was a very attractive woman just sitting there at her kitchen table.
“Hi,’ she said non challantly, “you must be the guy I’ve heard so much about.” ‘
