A Demon Sheds His Chains

I’m a demon who’s been forced to serve mages for far too long. So when I’m given a rare chance to seduce my master’s daughter into removing the ring that keeps me impotent, I jump at it, even though it means following her every command in bed. What she doesn't know is that if she removes my ring, I'll be free to do as I please. And it would please me to get revenge by using her tight fertile body.
