I didn't see anything out of the ordinary, am I missing something?
Maybe we have different definitions of explicit. But there are several close up full frontals of both actresses that are from behind the scenes, including the main actress getting her pubes shaved by another woman. In addition you can also see one of the actors fully nude, in the last sex scene. Beside that, in my opinion the video gives an interesting look into how scenes like these are filmed, and what the actresses/director thinks about during the movie making process.
But you are right, none of the three big sex scenes are included, despite how comfortable the main actresses appears to be standing around being filmed completely naked. This seems to have been a clear line.
A shame because the scene with the threesome or the fake penis would have been interesting to see. It seems likely the studio has footage of this as well, perhaps if you contact them, they would be willing to put it out in a new DVD or VOD extra feature.
