Perhaps they love the freedom of fanfiction. Fanfiction allows for different scenarios and character developments that may not be possible in the original works.
It could imply that they find a sense of escape or entertainment in fanfiction. Fanfiction often allows for different takes on existing characters and worlds, and perhaps Lincoln and Leni are drawn to that. They might like exploring new storylines and relationships that are not in the original works through fan - created fictions.
Well, Leni and Lincoln are the central figures. Leni, with her fashion - loving and somewhat naive nature, and Lincoln, the creative and often put - upon brother. In this fanfiction, they are the focus as their relationship takes on a new aspect with the act of kissing, which will likely involve other characters from their family reacting to this new development.
Fanfiction can cover a wide range of themes and content. However, if it involves pregnancy in a context that might be considered inappropriate or not suitable for younger audiences, then it's not appropriate for all. It really depends on how the story is written and the nature of the relationship depicted. If it's written in a more innocent, family - friendly way, it could potentially be okay for a broader range of people.
One possible plot could be that Leni and Lincoln are in a situation where they accidentally kiss during a game or a prank gone wrong. Then they have to deal with the awkwardness and figure out their feelings towards each other.
One popular story might be about their adventures in a magical land. They could face challenges together and learn about friendship and loyalty. For example, they might have to solve puzzles to find a way back home.
One common theme is the exploration of their family bond in a different way. Since they are siblings in the original show, fanfiction might play with the idea of a closer, more romantic - like connection while still keeping the family essence in a way. Another theme could be growing up together and facing challenges as a 'couple' within the family setting.
This kind of fanfiction often raises serious ethical concerns. Incestuous themes, like the one suggested in this title, are generally not acceptable in society. It goes against moral and family values. Such content can also be disturbing for many readers, especially those who are fans of the original work and expect positive, healthy storylines.
A common theme is family support. Since they are siblings in the Loud House universe, many fanfictions explore how they support each other within the family dynamic. For example, Lincoln might help Leni with her fashion business ideas, or Leni might be there for Lincoln during his school problems.
