You'll never believe what happens next. All these young, pretty women take off their clothes, get paired up with a man, and start having perfectly synced sex on the mattresses they're standing on. I don't know what to call it. X-rated fascism? Is it a cult? A scientific experiment? A hands-on sex ed class? A piece of art?
My guess is the latter.
Pictures after the jump, but don't look if you're squeamish or if you're under 18. And if you have any info on what this is all about, please leave a comment. I'm curious.
