I'm not sure specifically about 'lemon' fanfiction involving Soifon and Yoruichi as it often involves inappropriate content. However, there are many great non - 'lemon' fanfictions about them that focus on their friendship, rivalry, and their roles in the Bleach universe. You can try looking on fanfiction - dedicated websites like FanFiction.net or Archive of Our Own and filter for appropriate stories.
One common theme is the clash of cultures. Naruto is from Konoha, which has a different way of life compared to Soifon's world. Another theme is the power dynamic. Naruto is a very powerful ninja, and Soifon is also strong in her own right. Writers often explore how this affects their relationship. And of course, there's the theme of love overcoming differences.
One common theme could be the relationship dynamic between the two characters during pregnancy. It might explore how they support each other or deal with the challenges.
A life - or - death situation might prompt the kiss. For instance, if Ichigo is about to die, Soifon, having some special power in her kiss, decides to use it to save him. It could be a last - ditch effort that involves a kiss, which then has unforeseen consequences on their relationship.
Well, one possible plot could be that they start off with a rocky relationship due to their different personalities. Ichigo, being more easy - going, and Soifon, being strict. But as they are forced to work together on some mission, they gradually understand each other better. Eventually, they realize their feelings for each other and get married. Their married life could involve Soifon trying to train Ichigo to be more disciplined in his powers, while Ichigo teaches her to relax a bit more.
Ichigo, the orange - haired protagonist with his powerful zanpakuto. He has a kind heart and is always ready to fight for what's right. And Soifon, the captain of the Second Division in the Soul Society. She is known for her stealth and combat skills. In the context of this fanfiction, they are the main characters whose relationship is explored, from their first encounters to their decision to get married.
There are indeed such fanfictions. In many of them, the authors create unique scenarios where Naruto and Soifon cross paths in unexpected ways. For example, in some, Naruto might be on a mission in Soifon's territory and they initially clash due to misunderstandings. But as they get to know each other better, love begins to bloom. It's a creative exploration of two very different characters from different worlds in the Naruto universe coming together romantically.
One possible plot could be that they are forced into a situation where they have to kiss as part of a mission or a spell gone wrong. For example, a powerful enemy casts a spell that binds them together and the only way to break it is through a true love's kiss. At first, they are both hesitant and angry about it, but as they get closer, they start to feel a strange connection.
I'm sorry, I don't have specific fanfiction stories to recommend. You can try searching on popular fanfiction websites like Archive of Our Own or Fanfiction.net. They usually have a wide variety of fan - created stories.
One challenge could be cultural differences. Naruto comes from a world of ninjas with its own set of traditions and values, while Soifon is from Soul Society which has a very different way of life. For example, the way they celebrate festivals or handle family matters might be completely different.
