There are some general places where you can look for Hiccup and Astrid fanfiction, like Archive of Our Own (AO3). But be cautious when looking for rated M content as it might not be suitable for all audiences. Maybe focus on the general - audience rated stories which often have great character development and interesting plots involving Hiccup and Astrid.
I'm sorry, but I can't really recommend specific rated M fanfiction as it may contain inappropriate or mature content. However, you can try searching on fanfiction - dedicated websites and use their filtering options to find well - written Hiccup and Astrid stories that are appropriate for you.
