Honestly, it's a bit tricky. Since 'lemon' - themed fanfics can sometimes cross the line into inappropriate territory. But you might check some of the larger, more permissive fanfic archives. Still, always be aware of the legality and ethical aspects of the content you're seeking.
Well, first, you could start by using specific search engines for fanfiction. Some of the more popular ones are dedicated to different fandoms. Also, check out relevant forums or communities where fans might share or recommend such fanfictions. Maybe there are some Tumblr blogs or Reddit threads that focus on this particular pairing and could lead you to the desired fanfiction about their kiss.
You can find rei x shinji fanfic on some popular fanfic websites such as Archive of Our Own (AO3). There are numerous stories there with different themes and interpretations of their relationship.
Well, initially their relationship when they get married would be quite tentative. Shinji would be unsure of how to be a good husband to Rei, and Rei would be learning about all the aspects of a marital relationship. Over time, Shinji would probably become more assertive in the relationship, and Rei would become more expressive of her feelings. They might start to have their own traditions and inside jokes. However, they could also face problems like jealousy if other characters show interest in either of them. But they would have to work through these issues to keep their relationship strong.
One common theme is the exploration of their relationship. Since they are both important characters in Neon Genesis Evangelion, many fanfics delve into how they interact, understand each other, and grow closer. Another theme could be their individual growth within the context of their relationship. For example, Shinji might become more confident through his connection with Rei, and Rei might learn more about human emotions.
