As I didn't wish to make my reply look like a thread from an old listserv board, I reply separately instead. My hope is, that it was made for profit, and wasn't a home video. There's a decent movie with Luke Wilson from the last decade on how internet porn got off the ground (ironically financed by a guy who was later suspected of embezzling the funds needed to make that movie and another one) and of course, there have been some outsiders who tried to cash in on that by way of selling things that weren't originally meant to be sold (imagine if they had known if they do like Terry Hogan and sue the outlet publishing it, making him probably the only guy richer while committing adultery... that reminds me, Stormy Daniels got busted on some bogus charges).
Anyhow, I've seen the clip at least half a dozen times. If there's more to be deduced I'm happy to share, but I have to disclose, I have a strong code of ethics. It's the mystery that interests me, but only if it's not private. I too hope it's not a home video, I don't like being up in other's businesses. As most of us don't have eternal memory, my second suggestion would be, that if those who have submitted this clip before, could remember at least where they posted it, the Wayback Machine could be used to reread those posts again. There have been cases in the past, especially with those of missing persons where independent factoids led to new findings. Without a further rewatch, some things are relatively common knowledge. Most companies are small and draw on a pool of local talent, which means shooting locations are within a state. If it's residential zoning, it must have been or was highly likely a mostly Caucasian suburb. The benefit of America is that there's a massive population number division between cities and suburbs, with the latter usually having an under 100 thousand township and 2 or 3 high schools.
But this latter would be based on the recording being done in a school. It was night, it could have been abandoned. The biggest obstacle is that neither woman's faces are visible, that may be the only thing which was done on puirpose.
