There might be a fanfic where Sasuke travels back in time to before Itachi committed the Uchiha massacre. Here, Sasuke tries to change the course of events, and their relationship takes on a whole new dynamic as Sasuke attempts to prevent the tragedy that tore their family apart.
One interesting Itachi and Sasuke fanfic could be about Itachi training Sasuke in a secret afterlife dimension. In this story, Itachi has the chance to pass on all his unspoken knowledge and skills to Sasuke without the interference of the outside world.
Some fanfictions focus on Sasuke finally understanding Itachi's true motives completely. For example, in a story, Sasuke discovers a hidden diary of Itachi that reveals all his selfless sacrifices for the village and for Sasuke. This leads to a very emotional reconciliation between them.
Another great Itachi fanfic could be a story where Itachi survives the fight against Sasuke. It could show how he then tries to redeem himself in the eyes of the village and reconnect with his brother on a new level. This would involve a lot of emotional exploration and character development.
The theme of self - discovery could also work well. As they get closer in a yaoi relationship, both Itachi and Sasuke could discover new sides of themselves. Sasuke might find that he has a softer, more understanding side that he never knew existed, and Itachi could realize that he doesn't always have to carry the burden alone.
One interesting storyline could be a story where Sasuke, Naruto and Itachi have to team up against a new, powerful enemy. They put aside their differences and combine their unique skills. Naruto's positive energy and powerful jutsu, Sasuke's sharingan - based techniques, and Itachi's strategic mind make them a formidable force. This kind of story could explore their growth as characters and how they learn to trust each other more deeply.
One interesting plot could be a story where young Sasuke dreams of surpassing Itachi not just in combat skills but also in understanding the true meaning of protecting the village. It could show their early training days with Itachi trying to teach Sasuke important life lessons in a more brotherly way.
The theme of sacrifice also often appears. Itachi sacrificed a great deal for Sasuke and the village. Fanfics might expand on this, like showing how Sasuke comes to fully understand and appreciate Itachi's sacrifices, and how that understanding changes their relationship.

One great 'itachi x sasuke x naruto fanfic' is 'The Bonds Beyond'. It focuses on the complex relationships between the three characters. It shows how their past experiences shape their interactions in an alternate universe.
I really like 'The Redemption of Itachi in Sasuke's Eyes'. This fanfic shows how Sasuke's perception of Itachi changes over time. It has some amazing character development and it also weaves in some great action scenes that are related to their relationship.
