Are you talking about his offer in season 5? I don't think I've read any fics with this plot... but if you want them just working together there are a lot of fics with this theme, some of which are written by yours truly :p

Great fic: Endevour..Its an AU where Justin also has a boyfriend before meeting Brian and Brian is cool about it. Not much angst, its not that fluffy either. I have it on PDF. Have you read it already? Or do you want me so sent it to you :)

Here's a link to a VERY LONG and completed story, just what you are looking for.

It's called "Forever Young" by JT Secrets. It's very good.
