Well, one idea could be focusing on their friendship instead of any romantic or adult - like relationships. For example, they could go on adventures together in the spirit world, helping out other spirits and learning more about each other's pasts. This would show their bond in a positive and clean way.
A family - friendly plot idea could be that Tomoe and Nanami team up to organize a festival in their town. They could be in charge of different aspects like decorating, inviting guests, and preparing food. Through this, they grow closer as friends and learn to rely on each other more. It would be a cute and innocent way to depict their relationship without any inappropriate elements.
One idea could be a scenario where Nanami and Tomoe go on a magical adventure together in a new, uncharted realm. During their journey, they face challenges that make them realize their feelings for each other more deeply. Another could be a story set in a modern AU, where they meet at a coffee shop by chance and start to develop a relationship from there.
Another idea is that the pregnancy is part of a prophecy. They have to figure out what the prophecy means for their child and their world. As Nanami's pregnancy progresses, she starts having strange dreams that give clues about the future. Tomoe tries to decipher these dreams while also taking care of Nanami. There could be a race against time to fulfill certain conditions in the prophecy to ensure the safe birth of their baby.
I'm not sure specifically as I haven't read that particular fanfic. But generally, it might involve their relationship, adventures they go on together, and how they interact in the fictional world created by the fanfic writer.
A plot could be where Nanami and Tomoe accidentally swap powers for a day. Nanami has to deal with Tomoe's fox powers and all the mischief that comes with it, while Tomoe has to handle being a land god and dealing with human requests. It would be a comical yet also a character - building situation.

And they have to deal with the reactions of the spirit world, some being happy for them while others are worried about the half - human, half - spirit baby.
