I watched the following recently:
Bobbi Starr – Massive Facials #1. Before, during and after, the off-camera female director speaks with Bobbi in a matter of fact way about what's happening.
An 'ALS Scan' scene with Nella, Jana and Faith by the pool discussing the location of their peeholes (one thinks hers isn't as visible as the others). They each open their pussies for the others to examine and comment upon which they do in a chatty, not sexual, manner.
A Putalocura scene with Maria Sousa where, in a corner, five of her friends – clothed – watch as she prepares for and then completes a bukkake session.
A Woodman Casting with Alice filmed in a real motorcycle showroom. The employees, two men and a woman, are occasionally shown looking on from a corner of the room as Alice gets fucked.
The first two scenes illustrate how the overblown moaning and groaning in the majority of porn just isn't necessary (it can put me off, in fact). I'd have loved for Bobbi's director to have been visible in that scene, it would have been even hotter.
The last two scenes are an example of how much of a turn on I find it to watch 'civilians' (women preferably) at a porn shoot. Especially if they were to interact with the performers by asking questions.
Sadly, I believe there's not much of this kind of material about. Unless you can tell me otherwise...
