When writing a 'dom Harry Potter slash fanfiction', it's crucial to develop the characters around the new relationship dynamic. Harry's friends, like Ron and Hermione, should react realistically to his new relationship. You can also explore the social implications within the wizarding community. If Harry is in a non - traditional relationship, how do others in the wizarding world view it? This adds depth to the story. Additionally, use vivid descriptions of the settings, from the Gryffindor common room to the Forbidden Forest, to enhance the overall atmosphere of the fanfiction.
To write a good 'dom Harry Potter slash fanfiction', you need to have a firm grasp of the Harry Potter universe's rules and lore. Incorporate magical elements into the relationship. For instance, how spells or potions could play a role in the relationship between Harry and his partner. Also, build up the sexual tension (if appropriate for the rating) gradually and realistically. Describe the characters' emotions and thoughts in detail to make the readers understand why Harry is in a 'dom' role and how it affects the relationship.
First, understand the characters well. Know Harry Potter's traits and how they can be adapted to a 'dom' role. For example, his courage could translate into being assertive in a relationship. Then, create an engaging plot. Maybe it's set during Hogwarts or in the post - war wizarding world. Make sure the relationship development is believable.
