Dom/Brian/Xander Cage - xXx crossover. I rec this separately from the rest of [info]khaleesian's stuff because I believe that in order to love this fic truly, you have to have seen ALL of the testosterone-laden canon, lust for Vin Diesel's body in an unhealthy way, and have at least a medium tolerance for crack!fic. Luckily, I meet all the requirements, and I say that this fic is hot, hot, hot ... plotty and sexy and with a kickass chase scene. Gotta love it.
