The titular character in this 1978 film is Suzanne McBain, who's mistress to sex mag publisher Doogan (Philip McCann). She fucks him on his desk, then breaks a popper of amyl nitrate under his nose so he'll cum quickly. (Early porn rarely hesitated to show the fun side of drug use.)
But Suzanne's just not a nice gal, as we quickly see when she teases photog Tony Richards after smoking weed with him. She lets him lick her pussy, then not only tosses him out abruptly, but phones McCann and tells him that he should fire Richards.
Cut to Richards doing stills on a cheesy porn set, setting up Sharon Mitchell and Eric Edwards in a tub full of pasta and sauce - then getting distracted by a would-be starlet giving him a b.j. and doggie fuck at his desk. Of course, Eric and Sharon find a way to stay occupied (b.j., pussy-licking, mish) in the tub, and, later, Tony convinces Eric to let him sneak in on a fuck session with old girlfriend Suzanne.
Retailing: An excellent performance by McBain will sell this to golden age fans.
