Spike bids on Buffy at a charity auction and wins her

I'm looking for a fic where (i think) Cordelia convinces Buffy to put herself up for auction for charity - and she finally caves. Spike and Buffy hate each other, and Spike bids a ludicrous amount of money on Buffy and wins her for the weekend or the week.

I remember a scene where Spike's mum helps Buffy make him breakfast in bed, and (possibly) another where he makes her wash his car in a little bikini?
