The President's Slave Girl

Erin Flynn is a nerd with a Master's degree in computer engineering. She is flattered to be asked to work at the White House, but didn't expect, as an assistant to a junior aide, that she'd see much of the President, until one day he dropped by to see her boss and had a look at her. From then on things seemed to happen at breakneck speed. It wasn't so much he was so handsome and suave, though he was, but that he was the President of the United States.
She could hardly say no! It turned out President Allen was a domineering, not to mention kinky man, and liked to tie her up and spank her right in the Oval Office! But if his wife found out, the steely eyed Victoria Allen would see to her punishment in a much more orderly fashion. And she found out.
