Xander is caught by demons, Spike must prove X belongs to him

[singedbylife.livejournal.com]

Can't remember if this fic was complete or not.

Xander has been caught by demons. Spike comes to get him out and in order to do so, he must have sex with Xander on some kind of stage. I believe that Spike surprises Xander by letting Xander top. (God, my reading pleasures are weird.)

Does this ring a bell to anyone? :D
