Produced in 1978, this obscurely packaged French offering is a scene-for-scene stroker. The urbane sexuality of the performers proves antidotal compared with Golden Age stateside smut. The cheesiness factor is minimal and the fucking classy and undated.

Essentially a tract on open relationships, the story follows a sexually aloof couple. With the assistance of a philanthropic millionaire and his Spanish sidekick (posing as their butler and maid) the swinging sex door is flung wide open. The sheer volume of group sex, girl/girl action and oral pops is impressive considering the running time.

And while the same few characters are repeatedly paired throughout, there's variation aplenty since sexual exploration and character development coincide.
