Numb3rs Fanfic Finders

it was a big long series, it started as Charlie/Don but then Cooper came in on Don. Don was very possessive of Charlie. I think it was by Penguinal but i'm not sure. it had at least 2 authors.I remember a scene in which Don and Cooper were being dominant over Charlie, but that's all I remember. It was a large series that all I remember.

I will be extremely grateful to any and all help I can get.
