There's probably some literature section on like every guro/'dark' forum (FetNoir, Dark Fetish Net, etc), but I've never much been to any of those, so I can't speak for the quality there. But /lit/ (including a pretty lengthy thread by yours truly, even if it's past the bump limit and I haven't got to updating in a bit) as well as some threads in /rp/ (the prompt-based short story ones, such as the stickied Killer/Victim and Finish Her and their derivatives; though the quality …fluctuates) is a good start There's also a relatively new subreddit of /r/deadlyerotica/. Just go and check out any of these, you're bound to find something.
