We haven't had a Venus with a snake for a while so here is a typically playful drawing by Eugene Reunier.
Our young Venus (or is she an Eve?) reclines under an apple tree while its serpentine inhabitant slides down to flick its tongue into her inviting pussy. This curious activity is being observed by a lurking lepidopterist. The young lady appears to then enjoy the man's own snake as they play in their very own Eden. Whether it is his dream, her dream or reality is not clear!
