If you liked Oedipus Orca for anything other than child themes, you will love La Orca!!
IMDB
Oedipus Orca is the sequel to La Orca both directed by Visconti and starring Rena Niehaus. In La Orca a high school aged girl played by Niehaus is kidnapped and held for ransom, while the second movie Oedipus Orca is about her life with her family and boyfriend after she returns home. The first film (La Orca) was somewhat controversial and labeled pornographic by some due to its exploitive nudity and sexuality involving a teenage girl. The first movie is actually pretty good with a great ending, while the second is less focused and sometimes seems like it was done purely as an exploitive film.
Enjoy
