Fun for Three (1974)

After one year of separation and extensive psychiatric treatment for cold-bloodily castrating one of her unaware lovers, the noble Countess Martine Bressac as she is driven home by the loyal chauffeur Mathias, finally, reunites with her husband Charles.

Without delay and in great anticipation, the Countess restlessly returns to her mansion's basement where she and her depraved husband used to quench their insatiable and perverted sexual appetite for young flesh, only to realise that her collection isn't complete. Encircled by a gallery of frozen in time human trophies, the Countess, once more, will go out hunting for young prostitutes to satisfy her fantasies, but it won't be long before Charles proposes to continue their voyeuristic activities with a rather unexpected present: Cécile, their 21-year-old virgin neighbour. Quivering with desire and almost insane to seduce her virgin victim, the Countess will try everything, however, will she manage to add helpless Cécile in her prized collection?
