Okay so no one knows where these screenshots came from but no one has been able to find the original video. Not even the fags at /b/. The guy who made this animation is call Grigori and he's nowhere to be found. Does anyone know where this animation could be? Here's the link to a video on xvideos that shows about 5sec of the whole animation http://sys.4chan.org/derefer?url=http%3A%2F%2Fwww.xvideos.com%2Fvideo24310309%2Fdexter_s_mom
Here's a list with all the pics
