Don't Hold Your Tongue by

Summary: I'm … not sure there is one? Seriously, this is pretty much straight-up PWP.
Notes: Deliciously hot rimming porn!

Summary: Heart-to-hearts aren't really McCoy's deal, but ground rules are.
Notes: This fic is sixth in a series, and while I certainly recommend the earlier stories, this delicious bit of porn stands just fine on its own. The image of a clothed Bones and a naked Jim in front of a mirror is too hot for words (and the fic only gets yummier from there).
