V of the Vengeance

The monster paid for me and then used me whenever he pleased.
He didn't realize I was planning my escape.
Once I got out, that's when I would seek my revenge.My sister depended on me to take care of her since our mother died. She was too young to know what I did to get us food and our tattered blankets to keep us warm at night during Chicago's bitter winters.
When she tried to help, it only made things worse. We were in danger, and I did what I had to do to get us out of it.
I sold myself to the highest bidder. Little did I know he wasn't just using my body, he was seeking revenge, and I was the pawn in his sick plan.
I could run, but every time he touched me, called out my name, my body told me to stay. That's what I did.
