Well, one unique feature is the combination of different universes. For example, when it crosses over with something like Doctor Who, you get time - traveling elements added to Destiel's story. Another is the new character interactions. When Destiel characters meet those from other shows or universes, it creates fresh and unexpected relationships.
One common theme is the exploration of forbidden love. Both Destiel (Dean and Castiel) and Sabriel (Sam and Gabriel) relationships often go against some sort of 'rules' in the Supernatural world. Another theme is sacrifice. Characters are often willing to sacrifice a great deal for their loved ones in these fanfictions.
I really like the Sabriel fanfic 'Gabriel's Return'. It has a great story line that involves Gabriel coming back to Sam in a very unexpected way. Regarding Destiel, 'Heavenly Bonds' is a great choice. It goes into detail about the spiritual connection between Dean and Castiel, and how it impacts their actions and decisions in the Supernatural world.
In fanfiction, 'destiel wing kink' often adds an extra layer of fantasy and uniqueness to the relationship between Dean and Castiel. The idea of wings can symbolize power, protection, and vulnerability. For some fans, it's a way to explore the deeper, more ethereal aspects of their relationship, something that goes beyond the normal physical interactions shown in the original series.
Well, it could mean that Dean is exploring different interpretations of his relationship with Castiel. Maybe he's curious about how fans see their dynamic.
There's also 'The Road to Us'. It's a bit of a longer read but well worth it. It delves deep into their relationship, exploring their past traumas and how they overcome them together. The story has a great balance between action and the development of Destiel's relationship, making it a very engaging read.
One common theme is the exploration of their relationship. The pregnancy often serves as a catalyst to deepen the bond between Dean and Castiel. It forces them to communicate more openly and face their feelings for each other.
Good 'destiel first time' fanfiction often has well - developed characters. The writer should stay true to the personalities of Dean and Castiel from the original show. It should also have a believable build - up to the relationship becoming more intimate. For example, if there's been a lot of unresolved tension between them in the story, the transition to their first time should feel natural.
In a Destiel - centered fanfiction where Sam is kidnapped, perhaps it's all part of some grand scheme to make Dean realize his true feelings for Cas. The kidnappers might be some over - zealous fans within the story who think that by causing chaos, they can bring about the Destiel endgame. They could hold Sam in some strange, other - dimensional location and send Dean and Cas on a quest to find him.
One common theme is the alteration of the timeline. Since they are time traveling, any small action can change the future, and often the fanfictions explore how Dean and Castiel deal with these changes. Another theme is self - discovery. Through traveling to different times, they learn more about themselves and their relationship.
