I suggested a Ten/Martha pr0n battle in the last modpost, some people said "yes please", so here's how it goes:
I'm nicking the format from
femslash_today (see one of their battles
here). Basically, you comment to this post with as many prompts as you can dream up. Tomorrow night I stick all the prompts in one post and people respond in comments with smutty fic - as short or long as you like, so long as there's sexx0rs.
Prompts can include: a situation, line of dialogue, kink, other partners to be included in a Ten/Martha/? threesome or moresome, a few words of a prompt, or anything else you think someone might be able to convert into smut. Doctors other than Ten are A-Okay.
And... go!
