I kinda thought it would turn out this way. If you remember I mentioned your wife might be watching you as you tended to his wife. It looks like your anxieties subsided once you got going and you were able to enjoy the encounter. Be careful this can become addictive. Hopefully in a good way for you.
No kidding. We are looking forward to the next experience. It was intimidating to start as I have been with the same woman for 30+ years. However, once we got going, all of that went out of the window. I was surprised that my wife admitted to liking watching us together. It has opened other doors.
My girlfriend admitted being nervous first time, and a bit excited. For me excited to have a new toy to play with, like a kid at Christmas.
