Another option is FanFiction.net, though the content there might vary in quality. Some Tumblr blogs also share and recommend good fanfictions related to them.
Popular tropes in their fanfiction include the 'rivalry - turned - friendship - or - more' trope. They might start off as rivals, competing in some aspect like who can solve a mystery faster or who is a better fighter. As the story progresses, this rivalry turns into a strong friendship or a romantic relationship. The 'in - over - their - heads' trope is also seen often. They get involved in a situation that is far more dangerous or complex than they initially thought, and they have to rely on each other to get out of it.

I really like 'Tim and Cassie: Growing Bonds'. In this fanfic, it starts with them having a bit of a misunderstanding which is really relatable. Then as the story progresses, they start to understand each other better and their friendship evolves into something more. It has some really great dialogue that makes the characters come alive.

I'm not sure specifically about 'lemon' fanfics as they often involve inappropriate or adult - themed content which is not suitable.

A good tip is to look for specific tags related to their brotherly relationship. For example, 'brotherly love', 'Tim and Jason bonding', etc. when searching on fanfiction platforms. This can help narrow down the results to the ones that really focus on their relationship as brothers. Also, some authors might have their own websites or blogs where they post their fanfictions, so keep an eye out for those in the fan community.
