the first one i am looking for is a xander/angel fic. i thought it was called inspired madness or inspired darkness. the fic started off with xander kidnapped by demons while in los angeles to get a book or something from angel - angel rescues him. the story has quite the kinks in it; from ankle socks to spanking giles at the magic shop. later in the story spike gets involved. they also plays with riley a bit.
the second fic is a female!xander/spike one. i think that xander was turned into a girl by a spell i think. anyways, spike took xander to new orleans. i can't remember more then that.
