It was bi to the extent that a person whom I presume was a biological female (we never actually saw what was between her legs though) did some sucking and also got fucked (and another reason I presume she was a biological female is that the guy put on a condom before fucking her, a courtesy that is generally limited in bi genre porn to women about to be vaginally penetrated, I presume as a precaution against vaginitis spread by insertion of a dick that had previously been in or brushing against an anus). But it looked like she bowed out partway through and the film went all gay.
