BangBus we all know is a 'work', as are practically all reality sites.
POV Porn Guy is the real deal. He is a pornstar scout and talent agent. That's his life, the scenes are shot in his own home where the girls he represents stay. So it's pretty real. Other than taking a camera out on the street and hitting up complete strangers and getting them to have sex on video in real time it's about as real as it gets. As far as I know nobody is doing that - without some fakery.
