if I did a story that would go in the 'celebrity' section of Literotica. i.e. it would be using the characters from an already existing story/universe that I would be using. I mean, TECHNICALLY, I could throw out a new character and story that was VERY obviously a rip off, but I would rather just not bullshit you guys and say 'Hey this is based on _____' I don't want to give it away yet, because if it's something you all wouldn't like then it's a 'why bother' sort of thing. But I can say that I'm almost 100% positive that everyone would know the story/universe it's from since it's a very well known one. (multiple movies, TV series, video games, books, etc.)
Let me know what you think!
