Wide Open (1975) aka Sängkamrater
You get the idea that this film is all over the place. It does strangely keep your interest though because you never have ANY IDEA what's going to happen next (all the sex and nudity helps a lot too, of course). It also seems to be some kind of strange male fantasy where completely unattractive, unsuccessful, and unambitious guys get to sexually use and abuse gorgeous women, and they love them for it. Actually this might be halfway plausible with the two sisters, who are both pretty ordinary looking, but girls like Lindberg and the blonde at the party are stunning beauties who could obviously do A LOT better. Still who knows what Sweden was like during the 1970's sexual revolution--maybe this film is entirely accurate.
