The Irish Jump Start is a sexual position where a man has doggy style sex with his women, right before climax the man attaches a defibrillator to each of the womans ass cheeks. When the voltage is switched on the sudden surge of electricity causes the womans vagina to tighten up.
I was banging this chick doggy style, and right before I busted a nut, I hooked up a defibrillator to her ass cheeks and hit the switch making her pussy get really tight. I gave her an Irish Jump Start.
