Used as a rendezvous for illicit lovemaking, two Paris apartments have a devilishly deceptive Two-Way Mirror installed between the bedrooms. Let's take a peek at what goes on when married couple inherits a key to each seperate love nest...without each other's knowledge. What you see is what you get in this passionate saga of lusting spouses that's worth looking into! First, fristky Francois gets the itch from the pitch of a well-hung door-to-door salesman..then she almoster over heats the phone in a steamy solo-session with an obscene phone caller...and finally this luscious libertine gets to intimately experience the sensuous secrets of her buxomly beautiful neighbor. ON the other side of the coin (or mirror in this case), Francois' hubby is steaming up the glass with just as many volatile and varied sexual experiences. Ultimately this carnal couple gets the picture on what's going on...but so what! NOw they can double their voyeuristic viewing pleasure...and keep an eye on each other at the same time!
