I'm curious why I don't see more of this niche -- an amateur girl getting fucked an amateur guy -- typically her boyfriend or husband, but with good lighting, direction, and other professional amenities. Maybe 10 years ago I remember there was some sort of series that focused on this niche, but I can't think of anything today.
The cool things about it are, the faces are fresh (and frequently young and beautiful), the chemistry is good, the sex is often better (if a bit more clumsy), the girls sometimes actually cum for real (and at unpredictable times), and the guys always have a full tank and tend to cum early and often (but don't hold your breath for a perfectly staged facial at the end).
Some of the best porn I've ever seen is when a college girlfriend/boyfriend make some extra cash on the side by doing what they love best, in front of a camera. Unfortunately, it seems to have disappeared from the American market, though I have seen some very good European am/am porn recently.
