One possible storyline could be about the moral and emotional turmoil that Faith goes through. She would have to deal with the unexpected pregnancy and the fact that the baby is related to Buffy in some way. Another could be how the Buffy - related characters react to this situation, like Willow trying to help with magic or Giles being his usual wise self in giving advice.
I'm not sure specifically about 'Faith pregnant with Buffy baby' fanfiction. Fanfiction can be quite diverse and spread across many platforms. You could try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net. They have a large collection of Buffy - related fanfics, but it might take some time to find one with this exact plot.
The First Evil could also be a great antagonist. It could try to corrupt the baby, seeing it as a new vessel to spread chaos. Since the baby would be part of Buffy and Faith, it would be a prime target for the First Evil's schemes.
Perhaps the story could be about Buffy and Faith being in a relationship first. Then, they decide they want to have a baby together. But it's not easy in their world. They may have to deal with the Watchers Council's disapproval. They'd need to find a safe place to raise the baby, away from the demons and vampires that are constantly after them. And they'd have to learn to rely on each other more than ever as they navigate this new chapter of their lives.

This kind of fanfiction also allows for creativity in exploring different settings and scenarios where this kiss takes place.
In many Buffy and Angel fanfictions where they have a baby, it often explores new dimensions of their relationship.

I really like 'The Bond Between Slayers'. It's a fanfiction that focuses on the unspoken connection between Buffy and Faith. It has some great action scenes as well as emotional moments that really bring out the depth of their relationship. There are also some interesting plot twists that keep you hooked throughout.
One common theme is redemption. Faith has done a lot of wrong things and many fanfictions focus on her journey to make up for her past actions. Another theme is the complex relationship between Buffy and Faith, whether it's a love - hate relationship or a growing understanding between them.
