Some of these appear to have been made in motel rooms. Did they shoot these waiting for some girl to show up? Or some lad? Others are clearly shot in military facilities. They might be the ones emailed home to their girlfriends or boyfriends.
Whenever I see military personnel waiting in an airport -- they are so easy to spot, their civvies notwithstanding -- I can't help but think of pictures like these. Strapping young lads pupped full of hormones and testosterone are very easy to undress with your eyes.
Of course, since some of these are phone images, they are not to best quality. To see a free online folder with all of these images, plus more than a dozen amateur military lads I didn't use, click here.
