O.K. I have come back to QAF after a few years absence having lovingly re watched the lot. I unfortunately have lost a large amount of bookmarks since then. There is a particular fic that is driving me mad and I really want to find it, if you could help that would be great.
It is a future fic, and I think it began about a year after the end of series five. It becomes clear that despite whatever everyone thinks they know, Brian and Justin are still seeing each other when they can, but are keeping it a secret, there is a sense that Brian does consider them married although they continue to see other people, they later chose to put on the rings but there is no ceremony. Justin is a successful artist, and there is a scene when Justin does a very large painting that is sold before his show is even opened. Later on they become monogamous but only because they want to fuck without condoms. This was a very long running fic made up of different books and it wasn't finished the last time I read it. Any help would be great.
Found! Thank you everyone. It was Xie Xie Xie's 'Only time' series
