"Ken" is not some approximation of "kin". Rather, Ken is a man's name. "Our" refers to the current and the previous girlfriends -- who meet and decide to move "Beyond" the guy who is not quite the great catch.
It seems Ken has been posting nude photos of the former girlfriend to an adult web site. Unfortunately, at least some her colleagues at the school where she works visit the site, and have shared it with the rest of the staff.
After learning about this, the current girlfriend decides to help the previous girlfriend -- perhaps with some revenge, but certainly with deleting the photos from Ken's computer.
But it's not quite so simple an action as one might think. And the girlfriends' relationship never seems to really move BEYOND Ken. Rather, he seems to remain somewhere at the center of their world, even as they bond more and more in their apparent desire to seek revenge.
Recommended.
