Hello, I'm from the Chains, whips, fetishes, OH MY! contest. The fetish is very taboo, you definitely reached that brownie point. I haven't heard of that fetish actually. Which is good. I love the idea of the prisoner having sex for more privileges. That's really new. I also like how he likes to listen to the story while he has sex with them. One thing that stood out was how the prisoner wasn't upset with what he did, which is realistic because normally that's how people act. So I will give you props on his story and his brutal crime.
So overall I thought the plot was very good.
