Another one of those videos where some pornstar is left flopping around like Terri Schiavo on speed after experiencing the Optimus Prime of all orgasms. This chick takes it a step further, introducing Human Bobblehead Mode at the 1:55 mark. All sorts of awesome.
I love how the dude stops laughing and goes completely silent once he realizes his girlfriend wasn't joking about having an orgasm. Sorry Peter, your cock just got one-upped by a cheap carnival ride. HUMILIATION.
