The theme of acceptance is also quite prevalent. In these fanfics, they learn to accept each other's differences, whether it's Jacob's wolf nature and Edward's vampire nature. And often there's a theme of redemption, like one of them trying to make up for past mistakes in their relationship.
Often, there are themes related to forbidden love. Since Jacob and Edward are from different 'sides' in the original narrative, their relationship in fanfic can be seen as something that goes against the norm. In lemon fanfic specifically, this forbidden aspect can add an extra layer of intensity to their romantic or sexual encounters. There might also be themes of self - discovery, as they learn more about themselves through their relationship with each other.
Well, AO3 is probably the best place. There are so many talented writers who post their Edward x Jacob fanfics there. The tagging system on AO3 makes it really easy to filter and find exactly what you're looking for. Another option could be Wattpad. Although it has a wider range of content, you can still find some great Edward x Jacob fanfics if you search carefully.
In many of these fanfictions, Jacob's character often develops a new sense of vulnerability. For example, in stories where he discovers he's pregnant, he has to deal with physical and emotional changes that he's not used to. Edward, on the other hand, might develop a more protective side. He has to step up and support Jacob, which is different from their previous dynamic.
Well, 'Moonlit Encounters' is a really good Edward x Jacob fanfic. In this story, they are forced to work together on a mission to protect their small town from a mysterious threat. As they spend more time together, they start to see each other in a new light. Then there's 'Forbidden Feelings' that plays with the idea of their relationship being taboo in their respective communities, but they can't resist the pull towards each other.
One great Jacob x Edward fanfic is 'Twilight Reimagined'. It explores a unique relationship between them that goes beyond the typical rivalries in the original story. The author delves deep into their characters, showing how they might overcome their differences and find common ground.
The themes in 'Edward x Jacob Lemon Fanfiction' can vary widely. Some common themes could be love against all odds, self - discovery within a relationship, or the exploration of taboos. Since Edward and Jacob are often seen as rivals in the original Twilight series, the fanfiction might be about breaking those barriers and finding a deeper connection. The lemon part could also symbolize a more uninhibited exploration of their feelings, away from the constraints of the original story.
I really like 'Edward and Jacob: A New Understanding'. This fanfiction delves deep into their characters. It has a great plot where they are forced to work together for a common goal and in the process, their relationship evolves in an interesting way. There are a lot of emotional moments and great character development throughout the story.
One common theme is friendship. Despite their differences in the original story, fanfics often explore how they can become friends or at least respect each other.
