A great fanfiction is the one where an alternate universe exists. In this universe, Naruto, Sakura, and Sasuke are part of a special team that is not recognized by the village at first. They have to prove themselves by taking on extremely difficult missions that no one else would dare to. Along the way, they develop a deeper bond and face many challenges that test their friendship and ninja abilities.
There might be a 'naruto sasuke sakura fanfiction' where Sasuke returns to Konoha earlier than in the original story. This causes a lot of tension as he tries to reintegrate. Naruto and Sakura have to help him deal with the villagers' mistrust. Along the way, the three of them grow closer as friends and teammates again, with Sakura using her medical skills to help Sasuke heal from his past traumas.
Rather than seeking lemon fanfictions (which usually contain adult - themed and non - official content), you could look for adventure - based fanfictions with Naruto, Sasuke and Sakura. There are some really good ones where they face new threats together, and Sasuke has to fully trust Naruto and Sakura again after his time away. These stories can be really exciting as they build on the original story's themes of loyalty and redemption.
Well, one fanfiction I read had Naruto, Sasuke and Sakura getting trapped in a time - loop that was really insane. They had to relive the same day over and over, each time with different events occurring and it was really interesting to see how their relationships developed in such a strange situation. They started to understand each other on a deeper level as they tried to break the loop.
How about a story where an unknown enemy creates clones of them? Naruto, Sasuke, and Sakura have to not only fight these clones but also figure out who the enemy is and why they are being targeted. Along the way, they might discover new powers within themselves and also learn more about their relationships with each other.
A great plot would be if they all time - travel back to their childhood days. Sasuke could use his knowledge of the future to prevent certain tragedies, Naruto would try to befriend everyone even earlier, and Sakura could focus on improving her skills from a younger age. This would also change their relationships in interesting ways. Also, a plot where they all get stranded on an unknown island and have to survive together while also dealing with their personal issues could be really interesting.
In a fanfiction, there could be a story where a mysterious enemy targets Sasuke, Naruto and Sakura specifically because of their unique bond. The three of them then have to go into hiding and figure out who the enemy is and what they want. Along the way, they rely on each other's strengths and grow even closer as friends.
A common plot in such fanfiction is Sasuke and Sakura's relationship being tested. For example, rumors start spreading in the village about Sasuke's loyalty again. Sakura has to defend him while also dealing with her own doubts. Or perhaps there's a plot where a powerful ninja from another village falls in love with Sakura. Sasuke then has to show his love for Sakura in a more obvious way to keep her by his side. This can lead to some really interesting character development and relationship - building moments.
One interesting fanfiction could be where they go on a joint mission that tests their friendship and teamwork in ways they haven't experienced before. For example, they might have to face a new type of enemy that requires all of their skills combined. Another could be a story set in an alternate universe where they are all part of a different ninja clan but still end up becoming friends and allies. And there might be a fanfic that focuses on their training days together, showing how they influenced each other's growth as ninjas.
One interesting story could be where their son has to deal with the legacy of his powerful parents. He might struggle to find his own identity in the shadow of Sasuke's skills and Sakura's medical ninjutsu fame. Another could involve him making friends from different ninja clans and having adventures that test his loyalty to his family and village.
One interesting story could be where Sasuke and Sakura go on a mission together after years apart. They start to rediscover their feelings for each other. Sasuke realizes how much Sakura has grown and changed, and Sakura sees that Sasuke has become more in touch with his emotions. They have to face a powerful enemy and in the process, their bond deepens.
