Summary/Challenge: A Season 5 Out of My Mind Rewrite. “You do me right and nothing bad will happen to you.” What if Spike didn't say that to the doctor trying to take out his chip, but to Buffy? How does it happen? How smutty can things get? That is completely up to you.
The only condition that is a must-have is that Spike says that particular line to Buffy and Buffy says back (however you want) “Is that a promise, Spike?”
Have fun with this one!
P.S. Bonus points if you get rid of Harmony and Riley in the process.
Special Note: This is based on a challenge from Sunnydalesis! Thank you for the wonderful inspiration, this has been one of my most fun forays into writing for this fandom yet and I owe it all to you. :)
