Biancaneve & Co. (1982)

Snow White is a young nymphomaniac princess, daughter of King Agesilao IV and the late Queen Domizia. She has a strong penchant for oral sex, so much so that she surpasses even Queen Crimilde “Quick-Mouth” at it. Crimilde becomes jealous and hires a hitman to kill her. The attempt fails, however, because the man is seduced by Snow White, who consequently loses her virginity. After escaping, the princess reaches the home of the seven sages (though in the film we learn the names of only four of them), who refuse to tell her how to get home so they can have sex with her. Meanwhile, Crimilde once again plots to eliminate Snow White, calling on the wizard Magone, who suggests that the queen transform herself into a man, coat her penis in poison, and then kill the young woman through oral sex. The queen does so, and the princess apparently dies. The sages realize that the only way to revive the girl is for the prince to take her virginity, even though Snow White has not been a virgin for some time. Then the sage Stronzolo steps in and welds her hymen back together with nothing more than an oxyacetylene torch. The seven get in touch with the prince and convince him to have sex with the princess, who comes back to life. The film ends with the two of them able to live happily ever after.
