It is not appropriate at all. Fanfic should generally focus on positive and respectful interpretations of characters and their relationships. Creating erotic content about them is not only in bad taste but may also make the fan community uncomfortable and is not in line with the family - friendly nature that many works aim for.
The popularity of Link and Malon as a pairing in fanfics also stems from the fact that they both are associated with important aspects of the Zelda universe. Link with his quest to save Hyrule and Malon with her connection to the land through her ranch. Their relationship can be used to explore different themes like love in the face of danger, the importance of home and family in a hero's life, and how two very different people can come together. Fanfic writers love to delve into these deeper meanings while also writing a sweet love story between them.
The unique take on the relationship between Link and Malon. If the writer can explore their connection in a new and exciting way, it makes the fanfic interesting.
One common theme is domestic bliss. Stories often show them living a peaceful life on the ranch, taking care of the animals and enjoying simple pleasures together.
Another theme could be the challenges they face during the pregnancy. This might include Malon dealing with morning sickness while Link tries to balance his heroic duties and being there for her. It can also involve the reactions of their friends and family in the Zelda universe to the news of the pregnancy.
I'm sorry, I don't have specific fanfiction to recommend directly. You can try searching on popular fanfiction websites like Archive of Our Own. There you might find various stories about Link and Malon in a pregnant situation, written by different authors with different takes on their relationship and the pregnancy plot.
You could also try searching on Fanfiction.net. There are often a good number of Zelda fanfictions on that site as well. Look for ones that are focused on the relationship between Link and Malon. Maybe start with the ones that have a high number of favorites or reviews as they tend to be more popular and well - written.
Another option is to look for Zelda - themed fanfiction communities on Reddit or other forums. Fans often share and discuss their favorite fanfics there. You might find some hidden gems about Link and Malon's married adventures, like a story where they go on a journey to discover a long - lost relic while also strengthening their bond as a married couple.
You can write about their adventures together. For example, they could go on a quest to save a village or explore a mysterious forest. Focus on their friendship and how they support each other during difficult times.
