I'm sorry to interrupt your fight discussion but from this picture standing on tube from behind it's really in the ass not in the pussy, you can perform meassurement if you don't believe the long line visibility of pussy and much more behind the image with dildo, so this is 100% in the ass. More than this check in the picture his face, not easy to accept the pushing of dildo.
Later I saw the movie, yes, if you see after 6:23 min the ass is punished not the pussy.
