One possible plot could be that a powerful and mysterious ninja casts a spell on Itachi as part of a revenge plan against the Akatsuki. This results in the MPreg situation. Kisame and Itachi then have to embark on a journey to find a way to reverse the spell. Along the way, they face various challenges and also discover new things about their relationship and themselves. For example, they might find that they are more in love than they thought and that they are willing to sacrifice a great deal for each other and the unborn child.
In this type of fanfiction, the plot might involve a unique medical condition in the ninja world that only affects a select few. Itachi unfortunately falls victim to it. Kisame becomes his main support system. The story could be about their struggle to find a cure or at least manage the pregnancy. There could be elements of political intrigue within the Akatsuki as well, with some members trying to use this situation to their advantage, while others are more sympathetic to Kisame and Itachi.
MPreg (male pregnancy) in fanfiction often involves creative and unique interpretations. In a Kisame and Itachi fanfiction with this concept, it could explore their relationship in a whole new way. Maybe it could be set in an alternate universe where male ninjas have the ability to bear children. Writers might use this to show a deeper bond between Kisame and Itachi, as they face the challenges of this unexpected situation together. It could also delve into how the Akatsuki members react to such a strange occurrence within their ranks.
One possible main plot could be the adjustment period for Naruto. He's used to being alone, and suddenly having Kisame and Itachi as his adoptive fathers would be a huge change. They'd have to teach him different skills. Itachi might focus on Naruto's chakra control and strategic thinking, while Kisame could train him in more physical combat aspects. There could also be a sub - plot about how the village reacts to Naruto being adopted by two former enemies.
Well, it could start with Naruto being in a tight spot, like surrounded by a bunch of powerful foes. Itachi and Kisame show up out of the blue. Itachi uses his Sharingan to confuse the enemies, while Kisame uses his brute strength. They manage to get Naruto out of there. Then, Naruto might be curious about their motives. Itachi could give some cryptic answers, and Kisame would just grunt. This encounter could lead to a series of events where Naruto, Itachi, and Kisame are involved in a bigger mystery that ties to the secrets of the ninja clans.
One plot idea could be a story where Kisame and Itachi are on a mission together in a mysterious land. They encounter various challenges that test their loyalty to each other and their organization. As they face these difficulties, they start to understand each other on a deeper level, sharing their past traumas and dreams. This could build a strong bond between them without any inappropriate content, focusing more on their friendship and mutual respect.
Friendship is a common theme. The reader character might form deep friendships with Itachi and Kisame, going on adventures together and relying on each other. Another theme could be mentorship, with Itachi or Kisame teaching the reader character new skills or knowledge about their world.
Power dynamics are also a frequent theme. Female Itachi and female Kisame are both strong characters in the Naruto universe. Fanfictions might explore how their powers interact with each other, and how they compare to other characters. Maybe they team up to take on a powerful enemy, or they have a power struggle within their relationship.
Another theme could be sacrifice. Itachi, with his complex past and motives, might have to sacrifice certain things to protect Naruto and their unborn child. Naruto, too, may have to sacrifice some of his dreams or relationships to make this new family situation work.
Another option is Tumblr. There are a lot of Naruto fans on Tumblr who might share or create fanfictions about this pairing. You can follow Naruto - related tags and search for the specific characters. However, the content on Tumblr can be a bit more scattered compared to dedicated fanfiction sites, so it might take some more effort to find exactly what you're looking for.
One interesting aspect is the re - imagining of the Akatsuki dynamic. With a female Itachi, the power balance and the way she is perceived within the group could be different. Her relationship with Kisame could then have an impact on how they are both seen by the other members. Another aspect is the potential for different story arcs. For instance, a female Itachi might have her own personal goals that are related to her femininity, like protecting other female characters or using her unique perspective to change the Akatsuki's goals in a more nurturing way. And this would all play out in her relationship with Kisame.
One popular one might be 'The Unforeseen Bond'. It explores a unique relationship between Itachi and Naruto where Naruto becomes pregnant. The story delves deep into how they handle this unexpected situation, their emotions, and the reactions of the people around them in the Naruto universe.
