yogahotwife for sure has the best amateur videos I've seen, such a shame she isn't active online anymore.
Theres also a couple that posts semi-frequently on reddit (all text, no pics). They claim to be real, and after reading their posts that stem from over a year ago, I've found no inconsistencies. They go by smittencuck and willfulminx. Very good reads that appear to be true.
As for fake stuff, dogfart is okay. They have a few very good videos that do almost everything 'right'. But too often they get cartoonish with it and go over the top. Some good ones would be Gianna Michaels, adriana chechik, and nikka noir.
