Geeky looking woman turns out to be a nymphomaniac

A geeky looking boy you could easily think as a kindergarten teacher or a computer geek turned out to be a nymphomaniac. She walks into a bar pretending to be a vulnerable catch. Thanks to her good looks, she easily gets a prey and then fucks him hardcore like a seaboyed porn star and videotapes the whole shebang to add to her exhaustive list of victims.
