As far as I know, no one has ever figured out the source for this.

Maybe you can.

The story, as it was given in early 2000 when this series first was shown, was that it's a Japanese pornography where the ball busting woman is blackmailed by a few perverted guys into humiliating herself in various ways. In this series of caps, she's forced to disrobe in front of the aerobics class she's covering, and continue the routine naked, without giving an explination to the confused regulars.

No other explination has ever been given, nor has a source ever been found. When Yahoo recently "uncapped" the size of their images on Yahoo Photos, allowing the full size versions of these to be downloaded and saved rather than the 50% zoom versions, I snagged them as fast as I could.
