Thanks to Tars Tarkas I’ve got a source for yesterday’s image. It’s actually a tumblr posting original content called Dudes in Distress. I’m so used to see copied content on tumblrs it didn’t occur to me that the original poster might also be the creator. If they happen to read this I’d suggest watermarking their excellent images.
As for the tumblr itself, it’s exactly as it’s name implies. Lots of shots of cute guys in bondage or relatively mild torment. If your preferences run in that direction, then I’d suggest checking it out.
