A pair of twins consisting of a brother and sister come and sit on your lap. They both ask for a pet rabbit. But they also mention that their parents said no and that they're not old enough to take care of a bunny on their own. You tell the two you'll take care of it and send them on their way.
Come Christmas day the twins wake up to find they've turned into a pair of sexy, voluptuous, mature women and were dressed in playboy bunny girl outfits. When they looked in their closets they found that every piece of clothing there had been replaced with sexy bunny outfits. The twins go and tell their parents whats happened and both are dumbfounded and horrified to see whats become of their children. And it only gets worse when the try to get the girls to change clothes as now when they wear anything other than sexy bunny outfits their clothes will disappear leaving them butt naked.
