40 the Hard Way (1991)

Synopsis

When four hot-to-trot fortysomethings gather for lunch at an exclusive eatery, the conversation quickly turns to items other than the menu. The women soon start gossiping about their philandering hubbies and trading sexy stories (which we then get to see in all their boobulous glory). Eventually, the plot picks up and the gals decide that if their men are going to play around, they certainly ought to be enjoying some extra-marital pleasures as well.
