Was hoping the picture would be fucking but it looks more like masturbating on a car. Girls can rub themselves against everything but I think for cars to be sexed there should some level of automotive penetration with the dragon.
Is the dragon the male or the car the male? Can the dragon be impregnated? Would a Ford offspring be less quality than a Ferrari offspring? What would a pregnant car look like?
And the most important question, if your car/dragon couple happens to meet a French Bugatti would your car next door Chevy wife NTR the dragon with the Bugatti? You could add extra triggering if the Bugatti was painted black too.
Got to consider these options.
