Andrea is willingly seduced by George. She loses her virginity that stormy night. Machaty and photographer Vaclav Vich make heavy symbolic use of the moisture. There is no nudity, but what is implied is powerful. With a hand held camera, Vich shows the walls and ceiling from Andrea's point of view as she rides the crest of her lust to orgasm.
Oral sex is performed on the young woman.
Her face glows and sweats with animal passion. The lovers crash in each other's arms only to awake later for more fire. The scene is one of the most sensual and erotic scenes I have ever seen. This is amazing because as I said before, there is no nudity. What there is, is a genius filmmaker who knows his subject matter and puts the essence of the character's heart on the screen through choice of camera angles, point of view shots and a magnetic performance by his leading lady.
