I was going to suggest it could be titled "Completed Stories" and just be one section when I finally realized what Veks is asking. There could be several types of stories that are completed, from normal to exotic and consensual to non-consensual, to have a section for each would be a waste I think, but there should be a way to define each of them so that those perusing them are not surprised by something they do not wish to read.
How about something like this? One section, titled as above and when a story completes people can PM me (I don't mind moderating the section) and I will move the story. As part of the title I can add what section it originated.
