Obviously, Naruto and Sakura are the main characters. Naruto is the one doing the babysitting, and Sakura is the one being babysat. Their personalities play a big role in how the story unfolds.
One possible plot is that Sakura is sick or injured and Naruto has to babysit her while she recovers. He tries to cheer her up by bringing her flowers from the forest outside the village. They end up sharing stories about their dreams and fears, strengthening their friendship in the process.
In some Naruto fanfictions, Naruto babysitting Sakura as a child could be really interesting. It might show a different side of their relationship. Maybe Naruto has to take care of Sakura because her parents are away or something. He could teach her some basic ninja skills in a fun and childish way, like how to throw a kunai accurately using a game.
In this fanfiction scenario, Naruto could also introduce Sakura to his training routine. He could show her how he practices his chakra control by climbing trees. Sakura, being the smart one, might quickly pick up on the technique and start to practice herself. This would not only be a great way for them to spend time together but also a way for Sakura to start her ninja training early. And Naruto would be proud to be the one who inspired her to start training.
Another plotline could be them going on a mission together as young ninjas. They face challenges and have to rely on each other. Maybe they get lost in a forest during a mission and have to use their respective ninja skills to find their way back. Along the way, they share stories and secrets, strengthening their bond as friends and comrades. This shows how they grow together in the ninja world.
Well, a lemon fanfiction usually involves some romantic or at least some sort of emotional relationship. In the context of Naruto, Kakashi, and Sakura, it could explore different scenarios. Maybe it shows an alternate universe where Kakashi has some sort of unspoken feelings for Sakura, and Naruto is caught in the middle. It might also involve some character development that is different from the original series, with the 'lemon' aspect adding a touch of romance or unrequited love.
The appeal could lie in the novelty. Since Naruto is male in the original, making Naruto female changes the whole dynamic. The lemon part might add a bit of a romantic or sensual allure for some readers who enjoy that aspect in fanfiction.
A lot of such fanfictions might deviate from the canon quite a bit. With 'fem Naruto', the power dynamics and emotional connections with Sakura could be reimagined. Some may focus on their friendship evolving into something more romantic, while others might explore more complex storylines involving other characters in the Naruto universe as well.
I'm not sure about specific 'lemon' fanfictions as they often involve inappropriate content. However, there are many great non - inappropriate fanfictions about Sakura and Kakashi that focus on their relationship in a more positive and platonic way, like those exploring their teamwork or Kakashi's mentorship of Sakura.
Regular Naruto and Sakura fanfictions usually focus on their positive aspects like friendship, love, and their growth as ninjas. But 'dark' ones might explore more negative emotions, darker storylines. And as for 'lemon', it's inappropriate content which regular ones don't have.
