seeking_spike | Lost fic, muliple pairing

Hi, I'm looking for a fic I remember reading quite a long time ago. It's Spike/Angel, Xander/Oz, Wesley/Fred and Gunn/Cordelia. It's a long fic in which they deside to bring down Wolfram & Hart by following a paper trail after they find out that W&H are paying off a senator, I think. They all go into hiding, moving every few months and taking turns working. I remember Angel or Spike working in a porn shop.

I think all this may happen toward the end though, because Wesley manages to get turned into a faun first and Xander gets turned into some kind of demon that runs really fast, maybe to cope with visions he's having. And Cordelia, Fred and Gunn all become werewolves and Cordelia and Gunn have cubs after an orgy scene in a cave...

I think it was quite good despite what it sounds like here. :)

Any tips would be appreciated.
