I love entertaining the idea of bots being attracted to earth vehicles. Maybe a bot getting so desperately horny and humping one is kind of like resorting to using a sex doll or pillow humping for them. Or maybe one who isn't so desperate, but simply finds a certain vehicle irresistibly attractive. Having to sneak onto the property at night to use it. Even better if there's a huge risk of them getting caught by the human who owns it, but being so tempted anyways.
I imagine a more reluctant bot starting by simply jerking off to it, but eventually can't resist the smooth metal, the glint of the windshield or the juicy shine of the paintjob and ending up frotting their array against it. Painting it in their transfluid, and being left with post-nut shame and a bit of a dilemma. Should they run off, reducing the risk of being caught at the scene of the crime, or figure out some way to clean up the evidence?
