Ornella Muti, Eleonora Giorgi - Appassionata (1974)

In Italian erotic drama with explicit father-daughter taboo Appassionata (1974), Ornella Muti plays Eugenia, the teenage daughter with strong incestuous desire for her dentist father (Gabriele Ferzetti). Eleonora Giorgi (as Nicola) has the earlier explicit sex scene with the father in the dental chair (topless, bush, intercourse), which triggers the daughter’s jealousy and final incest act.
