'Watch what happens when twin brothers are the owners of a car shop. The only thing is . . . they like to switch identities to fuck with their friends and to fuck over their enemies! Two full hours from acclaimed director Csaba Borbely.
In Doubling Down, insatiable Mario McCabe does some industrial spying on classic car collection owners Fabrizio and Fernando Mangiatti, two hunky and horny twins. Competition is stiff these days, so Mario poses as a tax collector to uncover their secrets for success. Instead, he gets read and has a threeway with classic car security guards Austin Rogers and Richard Madison on his way out of the car salon. But just before that happens, customer Andreas Harris is in the market for something with twelve cylinders, so the twins oblige him by offering up their classic car lackey, Kevin Cage, to top him.
Next, Mario falls asleep in the back of one of the cherry condition roadsters and dreams about sexy Breno Lopes topping gorgeous Marco Sanchez in many classic and some new ways.
Mario figures out the twin angle as one of the secrets to their success, then discovers that they have sex with their customers, making business brisk indeed. In order to convert Mario to their side, the twins plug him in both ends at the same time in various and creative positions, showing how twin brothers can carefully enjoy a threeway together without touching each other even once!
After that kind of treatment, Mario applies for a job on the spot.'
