Comment with your choice of fandom, pairing (if any), and brief prompt and I'll try writing a 3-sentence fic for it.
No guarantees, but if I know the fandom well enough and it's not a squicky pairing for me, I'll do my darndest (see my fic pages for my OTPs and fandoms I've written before, but the stuff under "Interests" or that you know I've seen is fair game, too).
Hat. Ring. Toss?
