Trading with the Monster

Sophie lives alone at the edge of the forest with her cat Milton and she's about to starve to death. A gypsy tells her about monsters that live in the woods, who on a full moon, will trade sex for food with humans. Desperate and starving she takes the plunge, and ends up getting so much more than food out of the deal, she can't wait for the next full moon to be taken by another monster over and over again.
