By Judicial Decree 2: Debt Slave (Unabridged‪)‬

Karin and Natalie went deep into debt to invest in a can't-miss, no-risk business deal, only to discover that there is no such thing as a risk-free investment. When the deal collapsed, they couldn't repay the bank, which in their world meant they would be enslaved and sold. 

But that wasn't the worst part: The worst part was their owner, Master Caine, who made young, beautiful girls bend for his enjoyment. Set in a world where enslavement for debt is the law, Debt Slave is the second book in the By Judicial Decree series by Commander James Bondage.
