One possible plot could be that Tsunade, due to some powerful and complex jutsu gone wrong, is magically bound to Naruto and has to follow his commands. Naruto, being the kind - hearted person he is, would be very conflicted. He might initially be shocked and try to find a way to reverse the situation. He could use Tsunade's skills and knowledge for the betterment of the village in a very respectful way, like asking her to train more medical ninjas or improve the village's defenses while still treating her as an equal in spirit.
Writing or reading about 'Naruto gets a futa slave' involves creating and promoting inappropriate and unethical content. The 'Naruto' series is mainly for general audiences, especially young fans, and such ideas go against the positive and family - friendly nature of the franchise. So, no, there should not be such a fanfiction.
The relationship would become extremely complex. Naruto, who respects Tsunade deeply, would be uncomfortable with the power dynamic. He would constantly try to find a balance between respecting her as a person and fulfilling whatever the 'slave' situation entails. Tsunade, on the other hand, would be in a position of having to follow Naruto's commands, which would be a huge shift from her normal authoritative role.
There might be some fanfictions with such a concept, but this is a rather unorthodox and not in line with the positive themes of the original Naruto series. In the original story, Kushina is Naruto's mother, and their relationship is based on family love and the greater Ninja world narrative.
It's likely not one of the most popular concepts. Fanfiction often focuses on more positive relationships or exciting adventures. The idea of one character becoming another's slave has a lot of potential for misinterpretation and might not appeal to a large number of fans. However, there could be a niche group of fans who are interested in exploring the power dynamics and character growth that could come from such a situation.
It can start with mutual respect. Naruto respects Tsunade as the Hokage and for her great strength. Tsunade, in turn, can see Naruto's potential. For example, Tsunade could start mentoring Naruto more closely, like sharing her experiences during the wars which Naruto hasn't been through yet. This would create a bond between them.
Perhaps a story where Tsunade and Naruto are on a mission together in a foreign land. They encounter various challenges and have to rely on each other's strengths. Tsunade's wisdom and experience combined with Naruto's determination and newfound powers could make for an exciting adventure as they face powerful enemies and try to protect the local people.
You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). These platforms usually have a large collection of Naruto - related fanfictions, and you might be able to find some specifically about Naruto and Futa Tsunade there.
One popular story might be 'Naruto and Futa Tsunade's Unusual Bond'. It could explore how their unique relationship develops in a world filled with ninja challenges. Another could be 'The Adventure of Naruto and Futa Tsunade' which might involve them going on a quest together and facing various enemies.
In this fanfiction scenario, Hanabi becoming Naruto's slave could also lead to some interesting character development for both. Naruto, who values freedom and friendship, might struggle with having someone in a subservient position to him. Hanabi, on the other hand, might initially resist but then grow to respect Naruto more deeply as she sees his good intentions and the things he can teach her.
