fricatrice

A lewd woman or prostitute.

And am asham'd you' should ha' no more forehead / Than thus to be the patron, or St. George, To a lewd harlot, a base fricatrice, / A female devil, in a male outside

One can imagine an ideal servent who serves out of pure love for his master, just as one can an ideal rustic who remains a ditcher from a love of nature, or an ideal fricatrice who spreads her legs a dozen times a night from a love of copulation. But one never encounters these fabulous creatures in reality.

A woman who masturbates.
