Made a Slave by 6 Men

My sweetheart had a pretty whacky idea. He wanted to lend me to his friend Paul. He, in turn, was supposed to educate me to be a slave who lets herself be taken by several men. Paul and his friends went very hard to the point with me. I was made into a willing woman, a real slave, by every trick in the book. Whereas, if I'm honest, I actually only get extremely aroused when I'm threatened with violence or treated with violence and humiliation. My upbringing lasted for one horrible night.... +18, very hard SM scenes, described in detail.
