Mona (1970) (also promoted as Mona; the Virgin Nymph) is a sexually explicit adult film that contains a number of unsimulated non-penetrative sex scenes as well as penetrative ones. The film is regarded as the second sexually explicit film to receive a general theatrical release in the United States, after Blue Movie (1969). Unlike Blue Movie, however, Mona had a plot, though there was more emphasis on the action.
