This is a "female" who enjoys getting railed but also enjoys eating pussy, thus she goes both ways. Only a female can be bi sexual, any male who thinks he is bi sexual is simply a confused faggot (see also cocksucking faggot) as there is no such thing as a male bi sexual. (see also bi-sexual)
We have some bi sexuals coming over later, so we can get them wasted and spit roast them while they eat each other out.
