I finally looked found a download for this movie with the lovely "Mette" in, and got it. She is the female star of the movie, although the lead appears to be the same guy from the Erotic Picnic shoot. He appears throughout the whole movie, whilst Mette is in the first 25 minutes and the last 11.
The film is just under 72 minutes, and whilst I couldn't fathom the thinly veiled plot, I can't say as I was bothered, as I really enjoyed watching Mette in motion, and the 35 or so minutes without her was pretty enjoyable, too. Some of the cum shots looked dubious, or at least enhanced with saliva, but most were clearly real.
My caps are in two galleries. I tried to put them in order, but due to software issues, I used two players at two different times, so whilst each gallery should be in chronological order, they overlap each other.
They are only of Mette and do not therefore feature the rest of the movie.
