Just the thought of a high-heeled porn star teaching sexual education courses in school is enough motivation to make most of us pretty eager to get back in the classroom.

However, when she announces that her carnal teachings will include fully nude, live demonstrations, complete with sonic vibrators and butt-plugs, the perverts and master-whackers of the world will beat the doors of the institution off its hinges with their scabbed-over meat-sticks just to get a seat.

Fortunately for the sexually-depraved citizens of San Francisco, there is now such a public educational series available. Kink.com is now conducting live, hands-on sex courses using porn star models to demonstrate the proper ways to tickle your old lady's get-me-off spots. Tonight’s lecture is on oral sex - taught by adult superstar Rain Degrey.

Don’t expect to come to a lecture and see a bunch of California’s beautiful people pounding some flesh, though. "They have to sit through a lecture before we get to the good stuff,” said DeGrey. “We do techniques, physical response and have a question and answer period before moving on to the demonstrations."

DeGrey says she has taught previous classes on the proper use of a strap-on and female dominance.

Representatives from Kink say that next week’s demonstration on female ejaculation is sure to be a graphic affair. So, you might want to find a babysitter that night, folks.

UPDATE: Big shocker, the oral sex class scheduled for tonight is sold out.
