Well, 'lemon' fanfiction usually contains inappropriate content. But if you're interested in Azula and Zuko - related fanfiction that is appropriate, there are stories that focus on their complex family dynamic. For example, some fanfictions explore how they deal with their father's influence and their own paths to redemption or power. You can search for these types of stories on fanfiction platforms by using relevant tags like 'Azula', 'Zuko', 'family relationship' etc.
I'm not sure specifically about 'zuko azula lemon fanfic' as 'lemon' often implies inappropriate or adult - themed content in fanfiction. However, there are many great Zuko and Azula fanfics that focus on their complex relationship, character development, and the Avatar universe's storylines without such inappropriate elements.
Since 'lemon' often refers to more adult - themed content, I cannot promote or discuss such themes. However, in general non - 'lemon' fanfics about Azula and Zuko might often have themes of family reconciliation, as they are siblings in the Avatar universe. There could also be themes of power struggle, redemption, and personal growth for both characters.
One popular one might be 'The Sibling Reconciliation' which focuses on their complex relationship and how they gradually understand each other better. It has great character development.

The relationship would change drastically. Before the pregnancy, they were often at odds. But now, they are bound by this new situation. Zuko would probably be more involved in Azula's life, and Azula might start to trust Zuko more. They would have to communicate better to deal with the upcoming challenges of having a baby, like preparing a nursery, choosing a name, and dealing with the reactions of their family and the court.
There are many fanfics out there, but 'zuko and azula lemon fanfic' might be hard to recommend directly because of its nature.

Some might show Zuko trying to help Azula redeem herself, which can be really engaging to read.
Some smaller fanfiction communities or forums might also have Zuko and Azula fanfictions. For example, certain Avatar - The Last Airbender dedicated forums where fans share their works. But these might not have as extensive a collection as the larger platforms.

A theme that frequently appears is the power dynamic. Azula is a very powerful bender, and Zuko has his own journey of becoming strong. How this power dynamic affects their relationship is often explored in fanfictions. Also, the idea of forbidden love is there. Given their family situation and the events in the show, their love might be seen as something that goes against the norms, which adds an element of drama.
