JAV porn has always been in the lead when it comes to good fetish content but they have really feel behind when it comes to Shota.
Porn in the States has produced some incredible content in this genre over the past couple years. Lots of hot busty MILFs in sexy lingerie servicing young dudes with passion. And unlike in JAV, you don't have the stupid mosaic, blurred faces and condoms.
EDIT: I will say that the upcoming ATID-535 looks decent and I like the unique theme/storyline of a gamer son nerd using his hotwife mom for sex.
