Well, if by 'stories' you mean an ordered series of text - possibly with some images, then Moodle can already do that.
Use labels in sections, its simply a text editor, so you can add what you want. Doing it in separate lables/sections allows a bit more control over the editing and moving around and layout than putting it all in one - eg. if the page gets too long set it to show one section per page.
OR
Use the book module to add chapters/subchapters
You could even use the lesson module to create the sort of 'self-guided' stories that were popular a few years ago.
If you have something else in mind, perhaps you could expand on what you mean so we can give you more suggestions.
