It could also be for revenge. Naruto might have unknowingly done something that offended fem Kyuubi in the context of this fanfiction. For example, he could have disrupted her plans or made an enemy of someone she cared about. So, trapping him in a henge is her way of getting back at him.

Naruto himself is always a central character in these fanfictions. His ability to transform into the fem Kyuubi form makes him stand out.
