You wouldn't recognize them as the same person because they're NOT the same person. The anus and slit in that photo above belong to our girl Belle Knox (Duke class of 2017), the slut holding her buttocks is a different whore named Sara Luv.

Re: the scars from cutting. I noticed them too. And, in fact, while watching some of Belle Knox's scenes with a lady friend, I pointed them out. This young lady seems to have had some teenage emotional issues, I said. This got my woman all worked up — sopping wet, in fact. The implicit degradation and emotional pain must've been some kind of powerful turn-on (it's interesting to note that this partner prefers the arty style of porn like X-Art, and doesn't go in for Facial Abuse or Kink.com). People are strange.
