Another option is Wattpad. Although it has a wider range of content, there are still some really good Carlisle and Edward mates fanfictions on there. You might have to dig a bit deeper as it doesn't have as refined a search for this specific topic as the other two platforms, but it's still worth a look.
There's 'Carlisle's Influence on Edward'. This fanfic focuses on how Carlisle's values and teachings have shaped Edward over the years. It shows their relationship from a more mentoring aspect, which is quite different from other typical fanfictions. It also has some really well - written dialogue between them.
There's also 'A Father's Love: Carlisle and Edward'. This fanfic focuses on the deep, father - son bond between them. It shows how Carlisle's unwavering support helps Edward through various challenges in their vampire existence. It has some really heart - warming scenes that show their connection on a different level than just being maker and made.
One common theme is the idea of an unconventional love. Since Carlisle is a vampire and Bella has her own complex relationships in the Twilight series, their pairing is outside the norm. So, this theme of a love that defies the usual expectations is often explored.
Typically, Edward Carlisle slash fanfiction often focuses on the relationship between Edward and Carlisle. It may explore themes like loyalty, family - like bonds in a different context, and the power dynamics between them.
One common theme is the family dynamic. Carlisle being the patriarch, his influence on Edward and Bella's relationship within the family framework is often explored. For example, in many fanfictions, he helps them navigate the difficulties of being part of a vampire family.
I really like 'A New Beginning in Forks'. In this fanfiction, Carlisle's wisdom has a great impact on how Edward and Bella handle the challenges in their relationship. It has a very engaging writing style that makes you feel like you're right there in Forks with them.
Carlisle, on the other hand, is usually depicted as a very composed and wise figure. But in the context of lemon fanfiction, he also has a passionate side. His relationship with Edward is complex, with a mix of deep respect and a more intimate connection. The lemon elements usually highlight the physical and emotional closeness between them, showing a side of their relationship that might not be explored as much in non - lemon fanfictions. They are often portrayed as having a relationship that is both secretive and intense, with their interactions being filled with unspoken emotions.
Maybe Carlisle is angry at Edward because Edward put the family in danger in the fanfiction. For example, if Edward exposed their vampire nature to humans carelessly, Carlisle, who values the safety and secrecy of their family, would likely be furious.
The theme of sacrifice also appears frequently. Edward might sacrifice his own desires or safety for Carlisle, and vice versa. In some fanfictions, this is shown through them protecting each other from other powerful vampires or from the human world's threats. It's really interesting to see how these themes play out in different fan - created stories.
