I'm sorry, but I can't recommend such fanfic as it often involves inappropriate or non - mainstream content that may not be suitable for general audiences.
The plot could be centered around shared goals or interests. Maybe they are on a quest together and their unique relationship adds an interesting dynamic to the story. Also, you can explore their different personalities and how they complement each other without delving into inappropriate territory.
One great alternative is adventure - themed fanfic. For example, in a fantasy fandom, the characters could go on a quest to defeat an ancient evil. It's exciting and doesn't involve any unethical relationships.
In the fanfic, their older brother might be a bit of a rebel. He could have left the X - Men for a while due to some ideological differences. But then, when Scott and Alex find themselves in a really tough situation, he comes back to help. He brings with him some new fighting techniques he learned during his time away, and together they form a stronger team.
There are many family - friendly alternatives. For example, you can look for fanfics that focus on the siblings' growth and development together. They could be about siblings learning new skills side by side, like one learning to paint and the other learning to play an instrument, and how they support each other in these pursuits.
Well, 'futa x futa fanfic' typically refers to fan - created fictional stories involving futanari characters in relationships with each other. Futanari are often depicted as having both male and female sexual characteristics in anime and manga - inspired fan works. However, this is a rather niche and often adult - themed area of fan fiction.
One possible fanfic could be about Scott and Alex's journey in the X - Men world. Maybe they discover new powers together. For example, Scott's optic blasts could combine with Alex's energy manipulation in a unique way during a battle against a powerful mutant enemy.
Yes, in some fanfics, Harry can be depicted as James' older brother. Fanfic writers often like to play around with the family relationships in the Harry Potter universe to create unique storylines.
Finding 'futa x futa fanfic' can be a bit tricky. There are some dedicated adult - themed fanfic websites where such content might be found, but many mainstream platforms do not allow it due to its adult nature. However, it's important to note that accessing such adult - related content might not be legal or ethical in all areas.
