spike asks buffy to pretend to be his date

hi looking for fiction where buffy and spike go off to a wedding or some occasion like that and he has hired her to be his date, i think she already works for him maybe a secretary or something. They end up falling in love but when its over i think they go there seperate ways but when he finds her im sure shes pregnant with his child. I thinkk hes always loved her and thats why he asked her to do this so he could get close to her thanks jamesjack

Not so sure about the pregnant part, but this story meets half your requirements: Wedding Propositions by smg fan.
Summary: Spike Pryce needs a last minute date to his cousins wedding. She has to be ready to go that night to London, he would be willing to pay of course, who's his date? Who else but an unsuspecting Buffy Summers.
Can be found right here on this website.
Hope it's the one you're looking for.

There is another one... but it was taken down.

Curiosity by Pale Rider
Summary: Buffy lost her husband Angel in a car wreck two years ago, her life seems so pointless, she regrets not having children and is now des-perate for a baby. She hates her job, but more than that she hates her womanizing boss. William Devlin. But when he offers her a bit of private work it will change her life forever. ~ This story is based on a story from an old romance novel I found

It was at TSR, later then @ Geocities. The wayback machine link doesn't work. At the moment the user profil on spuffyfantasy doesn't open. The story was there, too. I'll keep trying and will add a link if I find one that works. *edit* It works now but it says that Curiosity isn't in the archive.

This story was written first (before the other one mentioned above). Spike needs Buffy as a date for a wedding.

Thanks guys the first story wasnt it but was still a good read. I think the one cordykitten has described might be it but wont be able to tell until i have read it . Hope you find it somewhere cordykitten i will keep checking backThanks heaps guys

I have this one; it's in an old Word format so I converted it to .pdf-file. There are online sites where you can convert it back to Word if you wish. Because it vanished when the sites vanished (@ GeoCities and Spuffyphantasy) I guess it's okay to share it. If you want it, sent me a message / email through my TSR profile. I've add the summary and the links first so it looks a bit weird but the text (the rest, the story) is okay.

Please tell then if it's the story in order for Pari to close this and move it to found ones.

Pale Rider is listed as an author at Sinister Attraction. This story isn't there and I don't think the site is updated any more but there's an email address which might be worth trying.

Curiosity does have Buffy getting pregnant but they never go their separate ways.
