Power dynamics is a big theme. Orochimaru has a lot of power and knowledge, and he uses it to manipulate Sasuke. Sasuke, in turn, is trying to gain power from Orochimaru while not being completely controlled. Another common theme is the struggle between good and evil. Sasuke is on a very thin line between becoming a tool for Orochimaru's evil plans and finding his own path towards redemption or justice. Also, the theme of mentorship is there, as Orochimaru is in a sense Sasuke's mentor, but a very unorthodox and dangerous one.
A good fanfiction could be about Orochimaru and Sasuke during the time when Sasuke is starting to gain more power. It might show how Orochimaru's experiments on Sasuke are not just physical but also mental. Sasuke has to struggle with his own identity and his new - found powers, all while being under Orochimaru's watch. And in this fanfiction, it could end with Sasuke making a choice that will change his future path, whether it's towards more darkness or a way back to the light.
It could develop in a very complex way. Maybe at first, it's full of hostility as Orochimaru has his own dark motives. But as the story progresses, Naruto's positive influence might start to change Orochimaru's perspective a bit.
In fanfiction, the relationship between Sasuke and Orochimaru is often complex. Orochimaru saw Sasuke as a vessel for his own resurrection or as a powerful tool. Sasuke, on the other hand, initially sought power from Orochimaru to avenge his clan. However, Sasuke was always cautious and didn't fully trust Orochimaru. This dynamic creates a lot of interesting plot points in fanfiction, such as Sasuke's internal struggle between his desire for power and his awareness of Orochimaru's true intentions.
In some fanfictions, Orochimaru could be a mentor figure to Naruto in a different sense. He might teach Naruto some dark jutsu not to use them for evil but to understand the nature of power better. Naruto, in turn, could teach Orochimaru about friendship and redemption. But of course, this is all part of the creative world of fanfiction.
The interactions between Sasuke and Orochimaru in fanfiction are significant as they drive character development. Sasuke's time with Orochimaru makes him more ruthless and power - hungry at first, but also more aware of the darker side of the ninja world. For Orochimaru, Sasuke is a key part of his plans, and his pursuit of Sasuke shows his ambition. Their interactions can also lead to different plot twists, like Sasuke turning against Orochimaru earlier or later than in the original story.
In some Orochimaru lemon fanfic, he might be portrayed as having a more seductive or alluring side. However, this is a very unorthodox view compared to his original character in the Naruto series. His intelligence and cunning nature might still be emphasized, but in a more sexually charged context which is not really in line with the official Naruto story.
In a fanfiction like this, the author might play with the idea of power dynamics. Orochimaru is a powerful and cunning shinobi, and Tsunade is not only strong but also a medical ninja with great influence. The "lemon" aspect could be used to show a different side of their relationship, perhaps a moment of weakness or a strange connection that forms during a difficult situation. However, this is all speculation as such fanfictions are not part of the mainstream Naruto narrative.
I'm not sure if there is an official "lemon" fanfiction about Orochimaru and Tsunade. However, if it exists, it might explore a rather unorthodox relationship between the two. Orochimaru is known for his devious nature and Tsunade for her strength. In a fanfiction, it could potentially show how their personalities clash or perhaps an unexpected attraction that goes against the norms of the Naruto universe.
Sasuke would likely be very guarded in his captivity. He would not show all his cards, even if Orochimaru tries to get information out of him. He may act cold and distant, only speaking when necessary. Inside, he's probably thinking about ways to turn the situation to his advantage. He could also be biding his time, waiting for the right moment to make his move. Given his goal of getting stronger to avenge his family, he might consider using Orochimaru's resources, but he would never fully submit. He's always aware of the risks and the fact that Orochimaru could turn on him at any moment.
