I have an idea for a Supernatural fic, but I don't feel like writing it because it'd have to be a series-type thing. Here's the idea, let me know what you think and if you want to write it! ^_^;
So, I had this dream last night where I was Dean and Sam's younger sister, either half-sister or adopted, not sure. But I had a secret love life with Sam that we didn't want Dean and John to find out about. When I woke up this morning I was like "OMG FIC!", and here I am.
The fic would start out with the girl (a couple years younger than Sam) finding Sam, Dean, and John and telling Sam and Dean that John either a) had her with another woman a couple of years after Mary died or b) had adopted her but kept her somewhere else, with a friend or something. John would of course own up to it when they confront him. She would know about the paranormal and would sort of know how to fight, but not really well. (Dean would have training sessions with her in the fic). So she insists on staying with them and helping. All of this takes place after the season finale. Sam and her grow close and romancing ensues. Depending on how you write this, it could be incest, so you'd have to be okay with that. I'm a sicko and I like reading lemons, so sex should be included. haha.
Humorous conflicts could arise with drunken guys that want to hit on her in bars and Dean and Sam play older brother. Also just with the normal brotherly bickering.
Other conflicts could involve Dean finding out about Sam and this girl being 'involved', you decide how he reacts. Another is the girl's mother or actual parent, again depending on how you write it, coming to try and take her back. Of course the girl would be an adult so she could choose not to go, but there could be issues nonetheless.
So, what do you think? Any takers?
