In fanfiction, Sasuke's protectiveness of Naruto and Sakura can be shown in various ways. For example, he might use his Sharingan to sense any approaching danger towards them. This could lead to some really intense and action - packed scenes where Sasuke jumps in to defend them against powerful enemies.
One example could be a fanfiction where Naruto stands in front of Sasuke and Sakura when they are facing a powerful enemy. He uses his shadow clones to surround them and protect them from harm. Naruto's determination to keep them safe is unwavering, and he even taps into new forms of his chakra to fend off the threat.
In a fanfiction, Sasuke and Sakura might be protective of Naruto in a more emotional sense. For example, when Naruto is doubting himself due to some rumors in the village. Sakura would be the first to stand up for him, using her sharp tongue to put the rumor - spreaders in their place. And Sasuke, in his own quiet way, would show his support by training with Naruto extra hard, as if to remind him of his strength.
In fanfiction, Naruto's past experiences play a role in his protectiveness. He has lost so many people already, and he doesn't want Sasuke and Sakura to be added to that list. He has seen the pain that loss can bring, like when Sasuke left the village the first time. Naruto is also influenced by his ninja way. His sense of justice and loyalty drives him to protect those he cares about, which includes Sasuke and Sakura.
Sasuke might show his protectiveness by always being near Naruto in dangerous situations. For example, if they are in a battle, she would quickly jump in front of Naruto to shield him from attacks.
A common scenario is during battles. Sasuke, with his Sharingan and combat skills, will shield Sakura from enemy attacks. For instance, if they are facing a powerful enemy ninja, Sasuke would put himself in front of Sakura to take the brunt of the attack.
Another theme is growth. As Sasuke becomes more protective, he also grows as a person. He learns to open up more, to trust his instincts about protecting Naruto. This growth can be both in terms of his ninja skills, as he hones them to better protect her, and in his emotional intelligence, as he becomes more attuned to Naruto's needs.
One common scenario is when they are facing a powerful enemy. Sasuke would put herself in harm's way to protect Naruto. Another scenario could be when Naruto is in an emotional distress. Sasuke would be there to comfort and protect him from any further harm. For example, if Naruto is feeling down because of the villagers' attitude towards him, Sasuke would stand up for him and make sure no one takes advantage of his vulnerable state.
Another way to discover these fanfictions is by joining Naruto - related fan communities on social media platforms such as Reddit or Tumblr. Fans often share and recommend their favorite fanfictions, and you're likely to come across some really good ones where Sasuke is protective of Sakura.
