Post-NFA, Spike finds out he has a baby

Hello,
Looking for the title and author of the following. At the end of the NFA battle, Spike gets wisked off by Giles. Also, Angel gets sent elsewhere thinking he's off to see Buffy. (I think Angel also shanshu's.) Giles brings Spike to an apartment in England, where Buffy lives. She reveals she has a baby from Spike (possibly twins). It was conceived with the help of the amulet from Chosen. (The Buffy in Rome was a fake to cover up the pregnency.) They get married. The story spins off into a series where they raise two children (Joy and Will). At one point, they get sucked into portals to different times seperately (Spike w/ Joy, Buffy w/ Will). I think one of the stories in the series has Angel (older and balding) still pursuing Buffy knocking on their home's door, while Spike & Buffy are in their beautiful bedroom. (There's even a painting of Victorian William pre-vamp that Giles had found, and Buffy won't let Spike get rid of it.) I hope I'm not mixing stories/series. Does any of this sound familiar?

Summary: (It's a Challenge Response)
All you know about Buffy in season 5 of ATS is a lie concocted by the Blackthorne. Buffy isn't in Rome dating the Immortal. She is in London with her twin Children William and Joyce. Imagine her suprise when she turns on the tv to watch news of the LA Apocolypse and sees her baby's daddy fighting the good fight. oh yeah Bitey goodness.

Looks like that may be the one (had to read a bit because I was thrown at first since I could have sworn it started with Giles rescuing him and we discover with Spike that he's a father). There's one more story by Starshine, then the series is continued by Redwulf through several fictions (all can be found on the same site for anyone interested). Can't wait to reread the rest and verify my memories of the other details. Thanks.
