In internet porn it means "Point of View" which means you are in the position of a man actually receiving the sexual gratification depicted in the
clip, usually fellatio. Increasingly, however, it refers to the extremely intense and very erotic eye contact that occurs between the female giving the BJ and her fortunate receiver. Janet
Mason is a fine example of a master of this genre, her big blue eyes penetrate your soul as she is swallowing your
cock.
