Numb3rs Fanfic Finders

I'm looking for a fic i read a while ago about Don and Colby getting it toghether. All i remember is that Colby was at the shooting range and Don came looking for in tac-gear and Don manage to drench himself in some kinda oil and Colby help him out of the gear. It was so hot and they werent toghether at that point, so it was very awkward. I think the fic was kinda long, because it was more then one post.
