I'm sorry, but I can't recommend lemon (suggestive or inappropriate) fanfiction. However, you can try looking for general Minato and Uzume fanfiction on popular fanfiction platforms like Archive of Our Own or FanFiction.net. There you might find well - written stories about their relationship, adventures, or character development that are suitable for all audiences.
Fanfiction should be a creative and positive exploration of characters. Instead of lemon fanfiction about Minato and Uzume, consider looking for ones that delve into their backstories. For example, a story about how they first met, their initial impressions of each other, and how their relationship evolved over time. These types of fanfictions can be much more fulfilling and appropriate to read.
Rather than seeking lemon fanfiction which often contains inappropriate content, you could explore fanfiction that focuses on the emotional bond between Minato and Uzume. Maybe a story where they team up to overcome a great challenge in their fictional world. You can search for such stories by using relevant tags on fanfiction platforms, excluding any tags related to inappropriate content.
