oh there are sites out there that find girls who have never done porn before nor come from an agent - but what's the difference - even girls who wind up with an agent are just normal(well that's a stretch) girls who are looking for money or a little excitement and at least their first shoot are true amateurs.
http://www.netvideogirls.com the closest to real as there is. i've been on the other end of the phone and listened to the girls calling - it plays out not much differently then the scenes on the site - he tries to get the girls over as quickly as possible to shoot the scene to make it as spontaneous as possible then hopefully the girl leaves and never shoots porn again.
pretty close to reality.
