Since nothing seems to be happening here, despite new members, how about a challenge?
I just took part in a delightful porn_battle, and thought something like that might liven things up a little.
Here's how it goes. You leave prompts (as many as you like) in the replies to this post, in the format pairing, prompt (example: Susan/Teatime, one time only). In a week's time I will close the prompting period and put all prompts up in a separate post. Then all and sundry (or at least our members!) can join in to write porn ficlets based on the prompts, and post them in comments to the that second post.
For fun and extra prompts by non-members, I'll leave this post unlocked. (The post with the actual ficlets will be locked.)
Of course if this is just a terrible idea, feel free to ignore me. :)
Edit: The challenge would, of course, also be open to fanart submissions.
