A deviant odyssey of psychosexual analysis begins as Hall-of-Fame XXX-auteur Rocco Siffredi greets visitors arriving for clinical exploration of their libidos. Built like a battleship, gorgeous blonde MILF Tiffany Rousso meets powerhouse Euro stud Vince Karter, playing a sex therapist. Tiffany, a teacher, relates her story: She's the object of desire for her male students. She the reveals her private, masturbatory sexual fantasies about two of them. In the fantasy, young studs Nikki Nuttz and Raul Costa jam their pricks in her mouth. She slurps their shafts in a lusty blowjob. Raul shoves his big cock in her cunt in spoon position as she licks and strokes Nikki's meat. The horny teacher's big tits bounce as Raul hammers her asshole in a vigorous anal fuck. Ms. Bombshell then takes Nikki up her ass, riding the young dude like she's on a merry-go-round. The guys excitedly trade Tiffany's orifices, spit-roasting Teach in a nasty threesome. Raul cums, spraying the older woman's mouth and face with a serious cum facial. Nikki douses her with his own soaking load of spunk.
