aka Il Dio Serpente

While vacationing in the Caribbean with her husband, a young Italian woman meets a female native. The two of them share in each other's culture, respectively going lingerie shopping and engaging in some frenzied, naked tribal dancing. Eventually they exchange lovers, except that her new black friend neglects to mention that her "lover" is actually a fearsome snake god!  V&D
