Two Whores, or a Love Story That Ends in a Wedding (1974)

A prostitute who works on the countryside complains about her loss of work because of the free love of the hippies. A fairy appears and promises to help her. Out on the motorway she stops a couple of cars with her magic wand. This way she manages to recrute a lot of boys for the bitch, who are queueing to wait for the prostitute beginning her services. A little bit later the queue starts disappearing, is shrinking, until the prostitute notices that another bitch has appeared, which is stealing her clients.
