I became the guardian of a slave girl was had been *d by her last owner.
At first things were weird. She was naturally distrusting, but through communication we became friendly.
A bond formed, and we went out together. I bought her clothes, she wore them.
As time passed I began to fall in love with her.
This game is about becoming intimate with a slave girl.
