These photos are interesting. They seem not to be shot by a professional, given one is slightly out of focus and you can see the young photographer reflected in the window. I checked the exif information embedded in the files, but almost all of it has already been removed so nothing additional was revealed.
Was this some class project and he convinced the blue collar bloke to shed his jeans? Or was he submitting his older boyfriend's photos to a porn site in the hopes he'd land some work? Or was he an out-of-work hardhat picking up a few extra bucks by posing naked for a young Wall Street type?
