We study compatible contact structures of fibered, positively-twisted graphmultilinks in the 3-sphere and prove that the contact structure of such amultilink is tight if and only if the orientations of its link components areall consistent with or all opposite to the orientation of the fibers of theSeifert fibrations of that graph multilink. As a corollary, we show that thecompatible contact structures of the Milnor fibrations of real analytic germsof the form (f\bar g,O) are always overtwisted.
