This one gets points for clever intentions: The conceit is that you're getting an "inside" look at a day on a porn shoot, where "civilians" (i.e. normies) mingle with "non-civilians" (i.e. porners) and, the way the vid imagines it, get overcome with the desire to fuck, themselves. Of course, these aren't really civilians - they're playing civilians - but it is a neat idea, from a creative standpoint.
The way the "real" footage is distinguished from the "performance" footage - the latter harder and more gonzo-ish - is pretty cool. What's more, there are a couple of great sex scenes, namely the Eve Laurence/Sascha and Tawny Roberts/Evan Stone pairings. Pre-nom the second for Best Coupling.
