Author, director, sex educator and so much more, Nina Hartley is the mother of all MILFs. The AVN Hall of Famer has ushered multiple generations into the knowledge of carnal pleasure through her countless features, most recently penning a book called "Nina Hartley's Guide to Total Sex", to give us mere mortals how-to guidance on delivering spiritual awakening-level orgasms and all sorts of tips and tricks to step your game up in the sack. The sex scholar and Jazz aficionado is most qualified to be dropping these gems on us: Active in the business since 1984, she's amassed decades of experience in the industry and has lived to tell about it. She even nabbed a role in "Boogie Nights", which was pretty much a mainstream primer on Porn History 101. Always outspoken, when she made an appearance on the Oprah Winfrey show and her audience kept grilling her, Nina stood her ground and insisted you could consolidate porn and feminism. It only makes sense that she of all people would fight the good fight. Her communist parents converted to Buddhism while she was growing up in the San Francisco Bay Area. It ain't just her mind that's open, though: momma got hella butt and isn't afraid of letting a cock or two slide up in it. Picture her baby blue eyes staring a hole into you while she slurps the cum out of your shaft. Or, watch her take a young couple to task, schooling them on how to get their fuck on right and joining in on the fun while she's at it. RedTube salutes Nina Hartley and has all sorts of videos and clips for your viewing pleasure.
