Facial expressions.
The look of shock and horror on the womans face when caught out.
The best 'Girls Caught Peeing' shots (in my humble opinion) are the candid
ones. They show very little in terms of sexual content but they provoke the
viewers imagination. All these women are natural and un-posed. They were caught by friends on camera when
they least expected or wanted it. Some smile,some look shy,some look angry.some try to laugh it off
and somescream. Its all in the facial expressions.
Look at these to see what I mean.

Caught peeing
 

Enjoy!

Just one capture from a video i recorded in may the one 2009. If you like it i can post more caps from the same video. Spoiler: the girl whose stream we see, saw me when she had almost finished.

Could you post the whole video?
or at least some more pics?

Pleeeeeeaaaaseee :-)

The whole video, with the format i have it in my computer, is too big. I prefer post more caps. Sorry if my english is awful.
