Considering I'm working on a final entry into the Bondage Challenge and other entries have been coming in as the clock ticks toward the New Year, I thought of recc'ing this comm I discovered about a month ago: slavefics. It's pretty cool, accepting slavefics and servant/master tales. There are both fanfic and original tales on this comm. They accept slash, het and gen. There's some DC there (including Smallville), Due South, Stargate: Atlantis, Supernatural, Torchwood, and many others.
Anyway, if you're in the mood for a little clinking of chains, check it out! ;)
