Change Machine, The
While fingering a girl you shove quarters in her vagina. You then proceed to bend her over, before she has climaxed, and fuck her in the ass. The pounding and her orgasm will result in change falling out of her vagina appearing like a change machine. For added effect, swipe a credit card in her ass before busting in it.
I pre-loaded my girl, then invited all of my friends over to show them my blonde change machine.
