This is continuing the monochrome theme with another image that I’m sure has been tweaked from its original form. I found it via the Happy BDSM tumblr. I’d guess it’s a StrapOn Dreamer image, but I can’t be sure of that, as there’s no watermark and Google image search seems to fail miserably on modified photographs.
Update: It is from StrapOn Dreamer and I even used it in a previous post. Doh!
