A photographer!

I look up to see a small but very attractive woman with short red hair that reaches her shoulders. Thanks to our height difference, it looks like I knocked her over during the collision as she's also sitting on her butt, though our circumstance are quite clearly different as I can feel the cold wind blowing against my bare body. She must have been holding a camera when I ran into her because it's laying on the floor next to her; she must have also worn a sunhat because it's sitting upside down next to her also...wait a second...OH SHIT!

I make eye contact with what the woman, who I'm guessing is a photographer, as her eyes go wide and a huge smile forms on her face. She grabs the camera and I hear a snap just before my hands go in-between my legs to cover my exposed penis. The red head looks at the camera before giving me a sadistic looking grin as she stands back up and walks over to me.

"Need a hand there, my nudist friend?" She sticks her hand out to me though I continue to sit there with my hands firmly in between my legs. "I already have a perfectly clear picture of what you're hiding there buddy, so why don't you let me help you up before I decide to start posting it online? I'm sure a few of my girl friends would love to see it!"
