I'm looking for domestic Spuffy fics ,fics where Buffy and Spike are in an established relationship and the scoobies know about them and they live together .
I'd prefer them to be fluffy and romantic but a little angst never hurt anyone

Although it may have more angst than you are looking for, my series, The Unexpected Universe, has a very domestic Spuffy with the Scoobs as friends. It doesn't start off that way, but gets there pretty quickly. (some say too quickly, but hey...)

It is a story of their life, so it has lots of ups and downs, thus it has angst as well as laughs, victories as well as defeats.

Everything in my Bumpverse (Things That Go Bump in the Night and its sequels) is fluffy domestic Spuffy - well, except for the angsty stuff in TTGB, but it comes out happily. Many or most of the short sequels were written for Schmoop Bingo prompts - very fluffy. My Always Wait For You is technically domestic, but they aren't together for all of it, so may be more angst than you're looking for. I Know You, II, a sequel to Prologue to Life/I Know You is Spike and Buffy working their way into a domestic relationship. It's shorter sequels take place after they've settled in. It's not about the domestic stuff, though, so probably not what you're looking for.

Of course, I presume you've already read Barb's epic fics? A Raising in the Sun, Necessary Evils, A Parliament of Monsters. Every story set in the Barbverse (after Raising) is domestic Spuffy. Which doesn't mean there isn't angst and bad stuff, but there's also lots of just being together and raising a family type stuff.

Barbverse:

A Raising in the Sun, Necessary Evils, A Parliament of Monsters


Summary: My take on Buffy's return from the dead. The Scooby Gang discovers Magnus Bryce's plan to Raise Buffy using the Scroll of Aberjian, and the race is on to stop him--but Willow has other ideas...

Niamh's Origin series of stories has them in a committed relationship living together. There's fluffy and angst - it's a huge tale so there's bound to be angst to make it interesting and keep you on your toes. The same goes for Mrs Muir's Baby Series, starting with Baby Did a Bad Thing.


Origins by Niamh

Summary: Post Season 5, veers from Canon, but uses elements that were seemingly left discarded by the writers.




The Baby Series by Mrs Muir

http://dark-solace.org/elysian/viewseries.php?seriesid=28

Summary: Series of four epic fics covering the Babyverse. Spike is called away by Drusilla before he can meet Buffy at the Bronze in Tabula Rasa. He doesn't return to Sunnydale until after the fiasco of Xander and Anya's wedding. Things aren't the same as when he left town...especially Buffy.
