Kasumi has been stuck at the bottom of the sales rankings for years, and the new president warns that she will be fired if she finishes last again next month.

The next day she unleashes her charms on every client, sends her numbers soaring, and escapes last place. Her unusual sales technique becomes the company's officially sanctioned secret weapon and takes her all the way to number one—but her runaway sexual appetite creates a whole new problem.
