Author: order_of_chaos
Pairing: No names actually mentioned, but intended Sparrington
Rating: NC-17, but only just.
Summary: Dialogue-fic aka. who doesn't think James could make someone come just by talking to them?  Is basically porn.
AN: Comments are loved and appreciated, but if I don't reply to them it's at least partly because I'm in Australia for the next week and a bit.
