Fast Fellatio & Furious Facial

I guess it's about time for the 'Fast & Furious' franchise to turn from car porn to, you know, actual porn. It seems only natural, given the amount of bromance between Dominic and Brian, that at some point they'll both get too horny fixing their cars and will get it on. Quite possibly, using engine oil for lube or something.
Also, Vin Diesel and Paul Walker would be a fucking sweet couple, don't you think?
