Improper etiquette Book

It begins with three ordinary women and their separate, unexpected discoveries of a lover's guidebook by Miss Matilda, the impish tutor of snag-a-man sexual decorum, circa 1949. All three ladies originally scoff at the hopelessly outdated, ridiculous etiquette book. But soon they find themselves leafing through its pages for some timeless, explicit, and very frank advice. What seemed like a relic of another time is about to open up a whole world of deliciously erotic possibilities for three modern women, learning to properly tantalize whomever they please.
