Sign of the times! Found it on the I Love Bondage tumblr. Google reverse image search suggests it may be a Facebook timeline cover image, but a search, though it turned up many such images, did not turn up the one I was looking for.
Well if you are wondering why some women might like bondage, sometimes a simple graphic says it all. Your girlfriend = generic, unsexy, merely female. Me = hot babe in bondage. Which do you suppose would get more attention, oh ... everywhere?
For reasons perhaps related to the image seen here! Image source: Sex and Submission.com.
