He might also try to reason with her. Naruto has a big heart and he would likely want to understand her feelings. He could say things like 'We're friends, we don't need to be this way.' He'd try to get her to see that her possessiveness is not healthy for either of them.
A more complex plot could involve the fem Kyuubi in heat influencing Naruto's dreams. In his dreams, she shows him a future where they are together, but in a rather possessive way. Naruto then has to struggle with whether he should accept this new relationship dynamic or fight against it. He might also seek help from his friends like Kakashi or Shikamaru, who could give him different perspectives on dealing with the fem Kyuubi's possessive behavior.
One possible reason could be that in the Naruto universe, Naruto has a special connection with the Kyuubi. As a female Kyuubi in fanfiction, she might feel a stronger emotional bond towards Naruto. She may see Naruto as her sole companion or the one who truly understands her, which leads to her possessiveness.
In this type of fanfiction, the fem Kyuubi's possessiveness might be manifested in her protecting Naruto at all costs. She could be overly vigilant and not allow any harm to come near him. This could lead to her interfering in battles or situations where Naruto might be in danger, even if he doesn't necessarily need her help all the time. She may also try to monopolize his time, not wanting him to go on missions with other people or make new friends. Her possessiveness could also be expressed in a more emotional way, like getting sulky or angry when Naruto doesn't pay enough attention to her.
One common plotline could be the conflict that arises between fem Kyuubi's possessiveness and Naruto's own desires for freedom and friendship. Naruto might want to explore and interact with others, but the fem Kyuubi tries to hold him back.
There could be a fanfiction where Fem Naruto discovers a hidden side of Fem Kyuubi. Maybe Fem Kyuubi has some memories or powers that were locked away and Fem Naruto helps her unlock them. This could set off a chain of events that not only changes the relationship between them but also has a major impact on the entire ninja world as they face new threats and opportunities together.
I really liked 'Fem Kyuubi's Bond with Naruto'. In this fanfic, the fem Kyuubi forms a deep emotional bond with Naruto. The author does a great job of showing how they support each other through various challenges. It has some really cool fight scenes where the fem Kyuubi's unique abilities are shown, which makes for an exciting read.
One great fem Naruto x fem Kyuubi fanfiction could be one that focuses on their unique bond. It might explore how they interact in a world where Naruto is female and the Kyuubi also takes a female form. For example, it could show them teaming up against common enemies and how their combined powers are different from the original story.
Well, Kyuubi might be possessive of Naruto because they have a unique bond. Kyuubi has been inside Naruto for a long time. They've shared experiences, and Kyuubi may see Naruto as its own in a way. Also, Naruto has sort of tamed Kyuubi to an extent, and this might make Kyuubi feel like Naruto is special to it, so it shows possessiveness.
In many fanfictions, Fem Naruto might show kindness towards the Kyuubi. This kindness could be something the Kyuubi has never experienced before. For example, instead of just seeing it as a source of power, Fem Naruto might try to understand the Kyuubi's past and pain. This could lead to the Kyuubi gradually opening up to her and them developing a deeper bond.
