Stories

So, I'm thinking up some more story ideas. Of course I'm going to keep writing my Divine Darkness story, but I have some other ideas, too:

Idea 1:
A girl is a Succubus will be the main character. Through her voice she seduces anyone (male or female), so to humans she is legally a mute. She finds herself kidnapped and put into a sex slave operation, and plans an escape. She's still not matured as a succubus, and she must drink a mature succubus or incubus's blood to become mature. One of her captors, the head of the operation, is an incubus, and she must fight her way into convincing him to help her.

Idea 2:
Underground fighting. I don't know what I'm going to do with it exactly, but I'm thinking of making it a story about a boy or girl who fights in the underground matches to find the murderer of his/her parents.

More ideas to come. Still working on the basics. Please let me know if either of these ideas sound good! Thank you.
