If anyone remembers, I once posted a season two story that begins on that night when Ethan cursed the costumes. Except Xander didn't choose to go as a soldier, he picked the vampire cape and cheesy fake teeth and a plastic sword to bop the children they were supposed to be taking trick or treating.

ADULT ONLY: bloodplay, domination, bondage, non-con, minor character deaths
And now.... the return of the Butterfly!verse with this sequel which doesn't even have a name yet.
