I like pictures like that!
Girls look very realistic, just like common people having fun, not like a "stars". And by the way, it reminds everybody that sex is about having fun, and the more people are participating, the more fun is coming out! especially with the camera on... In school I was fond of creating amateur (non porn) short movies with friends, and it always was a lot of laughing at every single frame, everything became so funny when you are filming a movie - just like you had smoked a joint!
as far as I know all the girls have to show their documents before any action, and to be photogoraphed with them. its kinda dull legal technicalities. but some girls seem to have a creative approach to the question
