If you want high-quality passionate erotica, look no further than this compilation of nude scenes from Exit (1970). We get to see Vibeke Lokkeberg topless on the stairs, we get to see her enjoy some passionate nipple sucking and we also get to see her gorgeous backside outdoors. If that's not perfect, we don't know what is.
Finally a Norwegian actress. She could have been a model at that time. :)
