First, focus on building their relationship. Start with how they meet in the How to Train Your Dragon world. Maybe the reader is a new dragon rider and Astrid helps them train. Describe their conversations, like when they exchange tips on flying or taking care of dragons. You can also include their adventures together, facing challenges like a new dragon species or a threat to the village. This way, you can create a strong bond between them without any erotic elements.
One key element is the setting. Since it's HTTYD, you need to describe the Viking village, the dragon stables, and the surrounding islands. Another is the dragons themselves. Maybe the reader has a unique bond with a dragon that catches Astrid's attention. Also, their personalities should shine through. Astrid's leadership and the reader's own traits, like being kind - hearted or having a great sense of humor.
Explore their cultural differences within the HTTYD world. If the male reader is from a different tribe, show how Astrid and he learn from each other. They could share stories about their tribes' dragon - related traditions. This kind of plot can be really interesting and family - friendly.
To write a non - erotic HTTYD female dragon x reader fanfic, first focus on building a unique relationship. You can start with the reader character stumbling upon the female dragon in a magical setting in the HTTYD world. Describe their initial encounter, like the dragon's curious gaze and the reader's mixture of fear and awe. Then, develop their bond through shared adventures, such as exploring uncharted islands together or facing a common enemy. Use vivid descriptions of the dragon's appearance and behavior, and the reader's emotions throughout the story. For example, when the dragon saves the reader from a dangerous situation, describe the reader's gratitude and growing trust in the dragon.
Astrid's character could develop in many ways. She may become more empathetic towards the other mothers in Berk. Before, she was mainly focused on her warrior duties, but now she can relate to the women who have to take care of their families. She might also learn to rely on others more, especially Hiccup, as she goes through the physical and emotional changes of pregnancy.
You can try searching on fanfiction websites like Archive of Our Own (AO3). There are often a wide variety of fanfictions there, and you might be able to find some related to Toothless and Astrid with the'sexy' aspect in different interpretations. Just use their search function and type in relevant keywords.
Another theme is self - discovery. The child in the fanfic is usually on a journey, both literally and metaphorically. As they interact with the dragon and other characters in the How to Train Your Dragon world, they learn more about themselves, their strengths and weaknesses.
Since 'lemon' fanfics are inappropriate, we can talk about common themes in regular Hiccup and Astrid fanfics. One common theme is their partnership in dragon - training and leading Berk. Another is their evolving romantic relationship, from initial attraction to deep love.
