Looking for Remus/Sirius, Regulus fic

[delonariel]

I'm looking for a story in which Regulus ends up living with Sirius and Remus. Remus isn't too happy about it because he thinks Regulus has romantic feelings for his brother. There was also something about an arrangement between them and Lucius, which included Sirius visiting him for favours or something.

I read this story some time ago and misplaced it while I was reading it actually. It's probably a WIP and I think it might be by Fleshdress/flutter, but I haven't been able to find it.
