A moody arty shot for this post. It’s a nice contrast of body position and language. For her it’s a forceful position, her legs open in a confident straddle. For him, with his body twisted and arms and legs folded back, it’s far more submissive. And that’s leaving aside the minor fact that she’s sitting on his face.
I’ve no idea why, but I always find that the black boots and tight white jodhpurs style trousers is a very sexy combination. Obviously they simultaneously emphasize the shape of the leg while concealing it, which pushes certain buttons. But there’s something about that specific color combination that’s particularly effective.
I found this on the Slaves of the Goddess tumblr site. Thanks to the magic of tineye I also tracked down a color version of it, although personally I prefer the black and white version.
