While strolling around Stockholm, an embassy worker becomes fascinated by an attractive older woman and a beautiful young girl accompanying her. He finally chances to meet the older woman and she brings him home and introduces him to the girl, Flossie. Moments later he and Flossie are exchanging oral favors (repeatedly). A half hour or so into the movie they finally take a break from the sex, and the man tells the girl the story of being seduced by three women and ending up the unwitting centerpiece in a sex-club orgy (Man, I hate it when that happens!). Flossie, in turn, tells him about how she was instructed in arts of masturbation and lesbianism at her strict boarding school for really, really sexy, overaged orphans. It turns out though that, aside from the masturbation, lesbianism, and oral sex, Flossie is actually an "untouched" virgin. The older woman is planning for the embassy worker to be her "first" (because he once converted HER from lesbianism and then apparently forgot all about it). She makes him hold off for awhile with Flossie and instead have sex with her. But, of course, he doesn't end up having to wait very long. . .
This is another very loose adaptation of Victorian-era literature by Swedish director/cinematographer Mac Ahlberg (he had earlier tackled John Cleland's "Fannie Hill" and Emile Zola's "Nana"). Between its somewhat classier-than-usual origins, its decent cinematography and music, and its avoidance of hardcore porn conventions (like extreme close-ups of pistoning genitalia and spraying bodily fluids), it ends up being a pretty tasteful affair overall. As Flossie, a barely (barely) legal Maria Forsa is definitely the best thing about this. Forsa was one of the most appealing "Swedish sin"-era beauties. She was perhaps most well-known for several movies she made with expatriate American director Joe Sarno. Kim Franck is also pretty good as the older woman, but like a lot of porn actresses she's saddled with a ridiculous matronly hair-do to make her look older than she really was (while Forsa, of course, is in pig tails at one point). The embassy worker, similarly, is played by a younger man with his hair dyed slightly grey to resemble a sophisticated middle-age playboy type.
Obviously, whatever "plot" this thing has never gets in the way of the sex. This isn't as good as Ahlberg's best films like "I, a Woman", but it's better than anything he did after he went hardcore, and it's worth seeing for Maria Forsa if nothing else.
