public "novelty photo booth" in a mall or something, you take your bf or gf in there and at first just regular pics, then you start getting naughty and flashing the camera and stuff, and then you get crazy sexy behind the little curtain...
The kicker is that in addition to the shots you take you can scan in the crappy little pics that the photo booth takes.
Get that nude in public, exhib, fear of getting caught thing going on and a nice little theme with a gimmick to wrap it up.
