Spander bdsm fic

[http://users.livejournal.com/_sharvie_/]

I remember it was post Chosen. I know Xander went to Giles and asked for help, he was feeling out of sorts and wanted to be dominated. And Giles sent him to Spike, only Xander didn't know it was Spike that was going to be his master. And Spike changed his accent so Xander didn't recognize his voice. They had sex before he had his blindfold removed. I know there was sex in front of a fire and on a big bed. Help?
