Another nice touch by Brandon Irons is he knew which girls he could get away with calling "bitch", "cunt", "hooker", and I even remember this one time he said "you piece of shit" as he ejaculated on a girl's tongue (i think in one of the slap happy vids)
In the ~20 years since Brandon Iron made these clips, it's quite possible that no one improved on his POV facials. The man knew how to direct these scenes, and extracted some phenomenal performances--often from girls who were borderline ugly (which kind of added a vile sexiness to the scenes). My all time favorite loadmymouth scene was with 18 year old brace-faced Faith Daniels. One of the greatest POV facials in porn history. Her interview was pretty hot too.
