La bambolona (1968)

Synopsis:
A bachelor attorney with a roving eye for beautiful women stets his sights on a 17-year-old student for his next amorous conquest. He meets with her parents, an economically troubled couple who soon give their consent for the couple to date. Using an engagement ring as an enticing lure to initiate sex, the lawyer gets more than he bargained for with the wily female who is wise far beyond her years. The tables are turned on the lawyer as she withholds her affections, feigns a pregnancy and ends up holding all the cards in the relationship with the older, "more experienced" attorney.
