Another plot idea is a story of self - sacrifice. For example, in a dangerous situation, Sakura and Karin both want to protect Sasuke. They put aside their differences and work together. And Sasuke realizes the importance of both of them in his life through their selfless actions.
One great 'Sasuke x Karin fanfic' is 'The Red - haired Bond'. It beautifully explores their relationship development. Karin's loyalty to Sasuke is depicted in a very heart - warming way.

I don't have specific knowledge about the common themes in 'karin x sakura lemon fanfic' as it depends on the creativity of the writers. But friendship or adventure could be possible themes.
A Sasuke Yandere x Sakura fanfic often explores a rather intense and possessive relationship. In such a fic, Sasuke's yandere traits would likely make him extremely protective of Sakura. He might go to great lengths to keep her all to himself, which could add a lot of drama to the story.
A lot of Sasuke x Sakura romance fanfic focuses on the emotional journey. There are the moments of jealousy, especially when other characters seem interested in either Sasuke or Sakura. The fanfics might also delve into how they communicate or rather struggle to communicate their feelings. Since Sasuke is not the most expressive, it creates a lot of tension and drama that makes the romance aspect more interesting. Some fanfics may also include flashbacks to their early days together in Team 7 to show how their relationship has evolved.
There's 'The Path to Redemption'. In this fanfic, Sasuke has to face the consequences of his past actions, and Sakura is there to support him. It's a well - written story that shows how their bond can grow stronger through hardships. It also has some interesting side characters that add depth to the plot.
Love triangles are a very common theme. Sasuke is often at the center of the attention of both Sakura and Karin, which creates a lot of tension and drama.
One common theme is friendship. Despite their differences and past conflicts, Naruto, Sakura, and Sasuke are often shown rebuilding their friendship in these fanfics. Another theme is redemption.

In the realm of fanfiction, almost any scenario is possible. Regarding Sasuke divorcing Sakura for Karin, it may exist. Fanfiction authors draw inspiration from the source material and then take it in new directions. The idea might stem from Karin's past feelings for Sasuke and some fans' desire to see how such a relationship shift would impact the characters. It could also be a way to explore the characters' personalities more deeply, for example, how Sakura would cope with such a betrayal and how Karin would handle being with Sasuke in that context.
