Well, it depends on your taste. There are fanfictions that focus more on the romantic aspect of their relationship leading to the kiss, while others might be more action - packed with the kiss as a side element. You could start by looking at the most popular ones on fanfiction platforms and see if they meet your expectations. If not, you can always try different search terms or filters to narrow down your search.
One common theme is the secret identity aspect. Kaito Kid's double life often adds an element of mystery and tension to the relationship, which can be a big part of the fanfiction. Another is the unrequited love or the slow - burn romance that finally leads to the kiss.
There are definitely some 'Kaito and Aoko kiss fanfiction' pieces out there. Some authors are really creative in how they bring these two characters together for that moment. They might add in some interesting plot twists, like a dangerous situation that makes the kiss even more intense, or they could write it in a more light - hearted and comical way, where it's a bit of a clumsy or unexpected kiss.

Another theme could be the element of surprise. Maybe Kaito is trying to keep his identity a secret from Aoko, and the kiss happens in a moment when she least expects it, which then adds a whole new layer of drama to their relationship. It can also be a theme of love conquering all, especially if there are obstacles in their relationship, like their different personalities or family backgrounds, and the kiss is a symbol that they can overcome those things.
The potential for a forbidden love story. Kaito's identity as a thief and Aoko's connection to the law enforcement side in a way add to the allure. It gives fanfiction writers a great canvas to paint a story of love that defies the odds and expectations.
In a fanfiction of their marriage, it might show how their relationship changes. Kaito, who was always so elusive, would become more open and affectionate. Aoko would be both excited and a bit nervous about this new phase. They could have a wedding where Kaito uses his magic skills to make the whole event extraordinary. For example, the flowers could magically change colors during the ceremony. And their married life could be filled with little mysteries and fun, like Kaito creating magic shows just for Aoko at home.
There might be such fanfiction out there. Fanfiction writers often come up with various scenarios for their favorite characters. However, it could be a bit hard to find just by randomly looking. You may need to use the right search terms on different platforms. For example, search for the names 'Kaito' and 'Aoko' along with the keyword 'pregnancy' on the relevant fanfiction platforms. If it exists, it may be among the results.
One possible plot could be that they face unexpected pregnancy and have to deal with the reactions of their families and friends.
One plot idea could be that Kaito decides to give up his life as a phantom thief after getting married. But an old enemy resurfaces, threatening their new - found happiness.
