The LadyFish Experiment

A beautiful woman appears on a beach in Florida, wanting to be bred. All she wants, is to grow very fat and very pregnant. Or so it would seem. But the man she chooses to mate with, is a widower and a recovering alcoholic. In her mind, he's the perfect mate.
Then he finds that she doesn't speak and knows nothing about normal etiquette. So, what is she? Who is she? As the story heats up, so does the temperature between these two.
