The Indiscreet Jewels

The Indiscreet Jewels (French: Les bijoux indiscrets) is the first novel by Denis Diderot, published anonymously in 1748. It is an allegory that portrays Louis XV as the sultan Mangogul of the Congo who owns a magic ring that makes women's genitals ("jewels") talk.

A comparable trope that Diderot must have known is found in the ribald fabliau Le Chevalier Qui Fist parler les Cons.
