As it turns out, she's indeed topless or fully nude in a number of scenes, but they're usually brief and the sex often can hardly be called erotic, and that's due to the nature of the character "Anita" she plays.

Anita is a troubled teenage girl who frequently seeks promiscuous sex because she feels unloved and unwanted by her parents, and until she meets her true love and fully trusts him, her sex acts are methodical and devoid of feeling rather than passionate and torrid.

None the less, even if the story's premise does not seem entirely convincing to me, it is interestingly told in a series of flashbacks and her relationship with Erik, the young university student who becoems her guardian, takes appropriate time to develop, such that toward the end of the movie the viewer does eagerly want to know when are they finally going to hop in bed and "do it."
