One idea could be a story where Katara and Toph go on a journey to find a rare and powerful bending artifact. Along the way, they have to face various challenges like difficult terrains that Toph helps them navigate through her earth - bending, and dangerous water bodies where Katara's skills are crucial. They also have to deal with other benders who want the artifact for themselves.
A plot could revolve around Katara and Toph starting a school for young benders. Katara would teach water - bending and Toph earth - bending. But they face problems like lack of resources, students with different learning abilities, and some parents who are against the idea. They have to work together to overcome these issues and prove that their school can be a great place for benders to learn and grow. This would show their different personalities coming together for a common good. Katara's patience and Toph's no - nonsense attitude would create a lot of interesting interactions.
I'm sorry, but 'lemon' in fanfiction often refers to adult or inappropriate content. So, I can't recommend such fanfictions. However, there are many great non - inappropriate Katara and Toph fanfictions out there. You can try looking on fanfiction.net or Archive of Our Own and search for their friendship - centered or adventure - based stories.

Or, it could be that she's kidnapped by a group of dark benders who want to study her waterbending to find a way to corrupt it. They might keep her in an underground lair filled with all sorts of dark magic - like contraptions.
One idea could be that they face challenges in a world not fully accepting of their relationship and impending parenthood.

A really interesting plot would be if the Nine - Tailed Fox in Naruto had some sort of connection to an ancient and powerful spirit in the Avatar world. The Avatar and Naruto would have to figure out this connection and use it to either control or understand the power of the Nine - Tailed Fox better. This would involve a lot of exploration of both worlds' mythologies and powers, and also some great character interactions as Naruto and the Avatar learn from each other.
