Sex of All Forms(1986)

Three unemployed masseuses (according to them, because of AIDS) are hired by three young men for an intimate weekend in a country house ("battleground", very common in the mythology of the genre). Sandra, the smartest of the three, says that they have already tried to make pornographic cinema, but now they are disappointed with the low level that prevails in the environment. They comment that producers in general are "picks". Actresses agree to make a certain film and then appear in several different films. This means that they recreate the same movie over and over again, without any qualms, changing the titles, etc.
