There were two rentboy fics written for merry_smutmas: Five Galleons and a Spearmint Sprig (http://community.livejournal.com/merry_smutmas/127154.html) and The Importance of Recordkeeping for the New Entrepreneur (http://community.livejournal.com/merry_smutmas/138572.html). Those are the only two I've seen in the fandom, though, which is too bad.
