Buffy brings gifts to Spike for mating ritual

Hi,

I can't remember the title or the author of this fic I'm looking for. I just remember that Buffy brings gifts to Spike as part of a mating or claim ritual. One of the gifts Buffy brought was a heart of a demon, I think, that was Spike's enemy. Spike recognizes that the gifts Buffy was giving was for the ritual because he used the same ritual for Drusilla but she didn't want to be mated to Spike. Also, I think Buffy offers her blood to Spike as part of the gift.

That would be, Death by Chocolate by maryperk. Found on her page [url=http://www.sinful-dreams.com/wicked/temptation/index.php][/url]

Thanks, that's the story I was looking for.
