Keller(2012)

In Keller, on his way to the underground garage Dominik Belko gets lost in a maze-like basement where he is pounced on by sex-starved security guard Lucio Saints. Lucio gets his beefy ass rimmed by Dominik and then rams his rod deep into Dominik's throat and asshole. Dominik's cock quivers with lust until he shoots his load in a wide arc.
