Intercambio de parejas frente al mar

Interesting erotic and semi-documentary movie... 　　"Intercambio de parejas frente al mar" (Couples meeting in front of the sea) is a curious film, an almost amateurish road movie featuring some couples who travel from Sevilla to the coast of Cadiz (a beautiful place, full of little white villages and wonderful beaches). The movie is erotic, there are a lot of nude scenes, and the acting is not too good (well, in fact the leads are not professional actors), but the film can be seen as a great documentary about the places that the couples visit. Good and very underrated, almost unknown.
