Kylie Jenner and Kim Kardashian Twincest For Instagram!

As an only child, I don't really understand the whole incest thing that sisters do when they get a little too comfortable with each other, I actually don't even see it happen that often outside of The Kardashian/Jenner family. So maybe it's less of a thing than we're let on to believe...

In typical Kardashian fashion, Kylie and Kim got together to snap some bikini clad selfies for Instagram this week and put on a show for the cameras, calling themselves twins as they pose together on a lawn chair!
