Perhaps a bit more from amateur sources.

Professional models are good, don't get me wrong, but there are too many sites that host professional models. Or "amateur" models who clearly are not. This might be a case of personal preference but I really feel that's what sets SF apart from every other name-brand porn cache out on the web. There is something about a girl naked with that shy smile and giggle that really makes the viewer feel good. It's sexy, and funny!
