That video has been around for years. It was debunked in the Autocunniligus group a long time ago. If she's really doing it, 1) they need to move the camera around so you can really see if she's touching it, 2) if she's really licking it her pussy would be wet from her own saliva.
The angle she is respective to the camera makes it appear as if she's doing it but I bet there's 12 inches between her mouth and her crotch.
