Since 'lemon' fanfics are not something I can promote in detail due to their potentially inappropriate nature. However, in a proper fanfic about Gohan and Trunks, it could show how they support each other in their growth as Saiyans. For example, they might share new techniques they've learned or strategize about upcoming battles.
I'm not sure about specific 'gohan and trunks lemon fanfiction' as it might involve non - canon or inappropriate content. But if you're looking for regular Gohan and Trunks fanfiction, there are many platforms like FanFiction.net where you can find great stories about their adventures and friendship.
Since 'lemon' usually implies inappropriate content, there are no positive aspects in that regard. However, if we consider a regular Gohan and Trunks fanfic, it can be positive as it can expand on their relationship and character development.
In such a fanfiction, perhaps future Gohan could warn present - day Gohan about upcoming threats that he has faced in his own timeline. He might share his experiences and knowledge, which could make present Gohan a stronger fighter and a wiser person.
There really isn't much that's acceptable in the context of 'lemon' fanfiction as it usually involves sexual or inappropriate content. However, if we were to consider fanfiction in general about Gohan and Trunks, themes like their friendship, training together, and fighting against common enemies are common and great.
One common theme is friendship. Since they are two of the last remaining warriors in a desolate future, their friendship is crucial. They support each other, whether it's in battle or in dealing with the emotional toll of their situation.

There's also 'Beyond the Saiyan Bond'. This fanfiction delves into a more spiritual side of their relationship.
