Maid in Sweden (1971)

Innocent, sweet 16-year-old country girl Inga leaves her isolated farm in the Swedish countryside to spend the weekend with her older, emancipated sister Greta and her good-for-nothing boyfriend, Carsten. And as statuesque Inga sets foot in the big city of Stockholm, she discovers sex, shatters her inhibitions, and gets in touch with her budding sexuality. But Inga's effortless natural beauty has already caught men's attention. Is sex as good as Inga thought it would be?
