Nina Hartley, Master Of Everyone’s Domain

[jwplayer id="7181831"]

With literally decades of sexual experience under her belt, Nina Hartley knows how it all works. She knows how to pleasure herself, she knows how to pleasure other people, and she knows how to pleasure other people by pleasuring herself.

Frankly, we're fairly convinced that Nina Hartley could launch a worldwide spontaneous orgasm with the right sequence of hand gestures—but since that could get pretty messy, it's probably for the best that she's restrained herself to simply masturbating for the camera.
