Nude Celebs: Claudia Koll - Tinto Brass ("Caligula") turns in another titillating tale of sensual obsession in this story concerning Diana, a married woman whose sexual needs cause her to stray from husband Paolo. Diana tries to get the kinks out with an older, buttocks-obsessed poet, but that's not enough for her. After Paolo throws her out of the house, she seeks to satisfy her orgiastic cravings with a number of partners of both sexes. Claudia Knoll, Paolo Lana star in Brass' bold bare bottoms-obsessed odyssey. AKA: "Cosi Fan Tutti." Dubbed in English.
