I looked around one last time. Redhead Marlene was standing a couple dozen yards from me, already barefoot. Next she was going to slip the dress over her head and start posing - naked on a university campus, in broad daylight. Then I saw him, just barely out of the corner of my eye - a man heading straight towards us. Just seconds ago there hadn't been anyone around. Shit... That's the way it goes. The normal risks of doing a nude shoot in a public place. You can't simply cordon off an area for some privacy, saying "Sorry folks, closed set." Our usual approach was to get in, get the pics and get out. Ideally without being seen - or arrested. And this particular setting wasn't one of those parks where people can lawfully lounge around half-naked: we were standing next to the Law Faculty building of a pretty conservative institution. And, despite it being a weekend-day, there were more people about than I would have preferred. We'd waited for quite a while to pick our moment - the wrong moment, it turned out. "Marlene," I hissed under my breath. She didn't seem to hear me. Her head was turned away as she glanced behind her, already starting to hitch up that dress. I knew that she wasn't wearing anything underneath - no panties, nothing. We didn't do wimpy flashing pics, we did full nudes - as the guy behind me would discover in a moment. "Marlene!" I repeated, somewhat louder now. At the same time I lowered the camera and began moving towards her. Hopelessly, I was trying to obscure the juicy view our unwelcome visitor was about to have...
