I'm not sure if there is such a fanfic specifically. Fanfiction can cover a wide range of scenarios, but this particular one might be a bit controversial in the context of the 'How to Train Your Dragon' fandom. It could exist in some corners of the fanfiction world, but it's not a common or widely known plot that I'm aware of.
Writing or seeking fanfiction with sexual content is inappropriate and often violates the terms of use of many platforms. We should focus on positive, non - explicit fan creations that celebrate the relationship between Astrid and Hiccup in a more family - friendly way.
Maybe she doesn't like the way some fanfics portray her relationship with Hiccup. Fanfics can sometimes deviate a lot from the original story, and she might be against those inaccurate or out - of - character interpretations.
One great Astrid Hiccup fanfic could be 'Astrid's Discovery'. In this fanfic, Astrid might find a hidden talent of Hiccup that no one else knew about. It could explore their relationship in a new light, with Astrid seeing Hiccup in a whole different way, leading to some really cute and heartwarming moments between them.
There are many fanfictions out there about Hiccup and Astrid's wedding. Some might focus on the elaborate preparations, like Astrid choosing her wedding dress which could be a traditional Viking style with a modern twist. The fanfic could also show Hiccup being nervous but excited at the same time.
There would be a shift in their dynamic as they prepare for a family. Hiccup, who is used to being adventurous, would have to focus more on home and stability. Astrid, while still strong - willed, would become more nurturing. They would need to find a new balance in their relationship, between their old selves and their new roles as parents - to - be.
A third theme could be about how they face challenges in their village. Like dealing with a shortage of food and they have to find a solution together. It can explore their problem - solving abilities and loyalty to their community.
One reason could be that the fanfic changes the essence of their relationship. In the original, they have a certain dynamic that she values, and fanfics might mess it up.
One great fanfiction is 'A New Adventure for Hiccup and Astrid'. It shows them exploring a new, uncharted island filled with strange dragons. The story really captures their adventurous spirits as they face challenges together and grow closer in the process.
