Season 7 Spike's Return

So I just spent over an hour trying to retrace my steps and can't find it. I'm looking for a fic that contains a seen where Buffy takes Spike out drinking and they come back to the house and get into the bed where Willow is already asleep. I think it was on ff.net and that it was S7 but it's possible it was post-Chosen or NFA. Ring any bells for anyone?

Found it! Possession by Shadowlass

Truly a rampant romp of a read!
