So, if you attended Northwestern, and you were taking a human sexuality class, what would you expect out of the class? Yeah, we're not sure, either. But you probably wouldn't expect an after-class demonstration of the female orgasm, complete with a fucking machine, would you? Even we were caught off guard.

“Both Professor Bailey and myself gave them five or six warnings about what was about to happen and it would be graphic,” said guest lecturer Ken Melvoin-Berg, co-owner of Weird Chicago Tours, who'd stopped in to talk about bondage, swinging, and other sexual fetishes.

Melvoin-Berg introduced an exhibitionist couple who enjoy having sex while others watch, and explained that the couple wasn't paid for their show. Then the woman undressed, and her partner used the saw/sex toy on her.

“We were watching a video on sexual arousal. They thought, ‘Why not give a demonstration?” Northwestern senior Justin Smith said. “The main guy, Ken, said, ‘Are you ready for the live sex show?’ We were like, ‘OK.’”

No one's filed any complaints, and no one seems damaged. So … let's all give the adult students of Northwestern a standing "O"? Yeah, we think so.
