Buffy/Dru Friendship

I was reading an old Kari Mouke story that featured a wonderful friendship between Buffy (who was mated to Spike) and Drusilla, and actually found myself liking the insane vampiress in that role very much.
So I'm curious as to if there are any other stories out there that involve that particular interaction between the two. Be it a friendship or a familial type bond, either encouraged by Buffy and Spike mating, or some other way. (Oh and just in case, I am aware and have read Maryperks 'First Chapters- For Future Use' story entitled 'Little Sister Found' which happens to be another example of exactly what I'm looking for.)
No Human though, I have no problem finding those types.
Any suggestions appreciated.

I think you may be looking for The Two Janes.

Enigmaticblue's His Tender Mercies features Drusilla as a human and "part of the gang," though I can't remember if there's specifically Buffy&Dru in there.

Thanks Melly, but I'm aware of the author, I'm just looking for similar stories featuring a Buffy/Dru friendship. Sorry if I didn't make that completely clear.

Thanks for the suggestion coalitiongirl. It wasn't exactly what I was looking for, but still a decent read.

You might try Born of Fire by Shadow.

It's here on SR, but it's still a WIP. The basic story is that Buffy disappeared after becoming the Slayer, and Joyce moved to Sunnydale alone. Living on her own in L.A., Buffy rescues Dru from some other vampires one night and begins caring for her. When Spike shows up looking for Dru, Dru decides to do some matchmaking between Buffy and Spike.
