Need Help Find a Movie

Back in the 90s I saw a movie late at night on Skinemax. It was a softcore flick, of course, and was about two girls who get abducted in the desert and forced into this weird role playing prostitution ring. People pay to have sex with the girls in certain settings and wearing certain costumes. I think one girl was dressed as an Indian at one point. Maybe virtual reality was involved with it somehow, I can't really remember.

I would actually like to know the answer to this too. I remember this movie, but, like Joe, can't think of the name of it. I remember the main girl character's name was Heather, because there was a stupid line where some dude said "Heather, everyone knows the moon is made of cheese."

Brad, i asked Josh about this, and even *he* didn't know...
