Zoomed out view of actress filming nude/sex scene

[shnowballs]

Has anyone seen anything like this before? It's a pair of videos I happened upon last week.

The first is a sex scene from a movie. I'm presuming it's a porno, I don't recognise it. Nice (Japanese I'd guess) lady is riding a fellow with great enthusiasm.

The second one though seems to be a behind-the-scenes documentary of the filming of the exact scene. In it we see the shot being set up: it begins with the guy on the ground and the lady taking off whatever garment she had been wearing as she arrived on set. Then there's lots of noise, director presumably shouting "action" etc and finally we are treated to a (too close IMO) shot of her in action, filming the scene.

I really love this. I don't think I've ever seen anything like it. Well, for real, anyway. I would have thought that if ever a film set was to be closed, it would be during the filming of a sex scene. And yet, this video exists!

Please feel free to add more if you have something like this in your collection.
