Confessions of a Sex Maniac (1974)

A prominent architect, Sir Bernard Storm, has accepted a lecture tour in the USA when he receives an offer, from Australia, to design a new leisure center. Unable to do the work himself he leaves it in the hands of his slacker assistant Henry, assisted by their efficient secretary Hilary. Henry, having trouble coming up with an idea for the design, in a drunken stupor hits upon the idea of modeling the building on the shape of a woman's breast. Naturally he then has to search for the perfect female breast.
