There’s a lot going on in this image. Rope bondage, suspension and breathplay just for starters. If there’s such a thing as a kink for being baptized, then one could add that to. It just needs a confused hiker in an anorak to wander in from frame left and you’d have public humiliation as well.
Regardless of the kinks on display, it’s a beautiful image. I imagine that setting the shot up would be a huge challenge. I just hope for the models sake that it was warmer than it looks.
This is from BDSLR photography and you can see the full sized version in their original post here. The models are Tifereth and Diaemone.
