Looking for a short-ish fic (longer than a one-shot though)
I believe Spike is Cordelia's older brother. She has a slumber party, one of the guests is Buffy. They're playing dares or something - and Buffy is dared to go and steal a pair of Spike's underwear. I think they're silky boxers, but I may be wrong. He catches her in the act and tells her that he'll let her off if she gives him her underwear. She returns to his room that night and they end up getting steamy.
Also, theres a bit with Buffy crying because Spike makes her go to sleep in the living room after - so he hears her crying and carries her back to his bed.
TIA
