The Slave Who Sold Herself

Colleen desperately needed money, but she had no chance of finding anything better than a dead-end, low paid job. She tried making money as a prostitute, but she detested the idea and found that the "johns" tended to rip her off. Finally, as the result of a chance meeting with a professional call girl, she was offered employment that seemed to be the solution to all her troubles: a one-year contract paying more than she had ever imagined earning.
Of course, it would not be easy. For one year she had to be a slave, and she was left under no illusions about it. Her duties would be sexual, kinky, and often painful. She would be kept as a prisoner, chained, bound and whipped (or worse) when her Master decided she needed punishment. But she had no idea that the Master's wife also intended to use her, and she was the real sadist.
