I used to work for a small gay porn company. One day I was looking through e-mails from the people who wanted to model and there was my neighbour! He was a ripped all-american guy and had a really sweet cock. What I thought was funny is that he's a straight guy, but he'd check the boxes "will get head from a man" and "will do mmf threesome". Tried to setup an appointment for him to come in, but he didn't respond. I guess he had a change of heart.
A friend gave me his old computer when he bought a new one. I never thought to look for anything on it. Months later, I did a file search for a photo I couldn't find and all of these nude photos of him and his wife showed up. Shocked to learn that she pegged him! Came to pass they got divorced and about 6 years later he answered an ad on Craigslist for a sofa I was selling. Ended up being suck buddies for a bit and he definitely loved having his ass played with which I probably wouldn't have done if I hadn't seen those photos.
Living in Fort Lauderdale, I've had the common experience of seeing the guy at the local diner, the coffee shop, etc. doing a solo for a porn company or fucking a chick for one of the sites in Miami.
