Buffy being in a vamp auction

There was a fic i read i don't know if it was here or not but it was a long time ago. Spike and a male original charecter (or someone not regular to the show) went to an auction. Spike has to be talked into it. Buffy is the slayer and being sold at the auction. They had been feeding her Vamp blood to keep her weak and young (not sure how that worked). Spike pretends to have the money to buy her then busts her out when they ask for the money... the last chapter i remember reading the OC was telling spike he would have to feed Buffy alot of blood to keep her alive... sound farmilliar to anyone?

Could it be 'Dream Girls' by Kantayra

There's also:

All That Heaven Allows by Isabelle
Summary: Buffy and Spike get kidnaped by an underground demon society to be sold for profit in an Auction. As the plot thickens so does thier relationship.

I know it doesn't quite fit your criteria but it's the only 'Auction' fic I can think of. But I shall keep looking. I posted this just in case it happened to be the one.

Icemink has one in which Buffy buys Spike, but that's the only one I can find. Oh! And there's also the Ring Around the Buffy round robin, completed by Anaunthe.

I don't think it's either of those, though. I'll keep hunting, but that's all I could find so far.

I have the story you're looking for :

Pleasant Dreams By Caitlin


Rating: At the moment PG-13 For bad language.
Relationships/Pairing: Buffy/Spike of course. But there might be more as we progress. You'll have to wait and see.
Spoilers/Notes: Alternate reality future universe. In this universe everything up to Season three is as it was, then Spike never returned to Sunnydale although buffy did find him in LA so that they could have the conversation they had in Fool For love. Everything in S4 happened as it did, but without Spike. Say that Season five didn't happen if it makes it easier. Buffy never found out spike loved her and spike didn't realise his feelings either.
Disclaimers: All Buffy related is Joss, Only Gunner, Marcus and the plot and ideas are mine. The lyrics are Faith No More (An excellent band which is alas no more) and the song is Strip Search.
Summary: Eight Years into the future after season three Spike is living in London and his life, or at least his unlife, has changed considerably. Currently tortured by his inability to feed and feelings of emptiness he is helped back to his old ways by his current companion Gunner, an African American Vampire who is his current hunting buddy. But when Gunner drags him to a bidding where half turned vampires, the vampires with the most powerful potential and potent blood are auctioned like cattle, along with humans and other demons he is in for a shock. Because it seems that his past and the chance to bring back that spark in his undead life hasn't yet died. smokey56_75670@yahoo.com email me an address
