Hi,
As soon as I read your request two fics popped into my head with major pampering by Spike. They are:
Help Yourself in Seven Days by ssddgr (aka Sotia)
Summary: Mid-Season Six. Buffy has a tiny little accident during patrol. She accepts Spike's offer to help her, but doesn't realize that offer encompasses much more than her wounded ankle until she is already chained up to the ceiling of the lower level of his crypt. It is now up to her to decide if she'll help herself, or not.

Summary: NC-17. Spike arranges a Christmas surprise for Buffy after her mother's death, but gets a surprise of his own. This is pure SMUT so please be warned! NOT FOR KIDDIES!!!!

Valentine Olympics by Schehrezade and RSK
