Well, a great fanfic in this regard would be one that explores the emotional bond between them in a new light due to Sebastian's wolf nature. It could show how Ciel might be both afraid and intrigued by this new side of Sebastian. The fanfic should also have good pacing, not rushing through the development of their relationship in this new context.
