One great Loki and Natasha fanfiction could be 'The Unexpected Alliance'. In it, they are forced to work together on a mission in a parallel universe. Their initial distrust gradually turns into respect as they face various challenges. Another is 'Loki's Redemption with Natasha'. Here, Loki tries to make amends for his past actions and Natasha is the one who has to decide if she can trust him again.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions and you can simply search for 'Loki and Natasha' in the search bar.

I'm not very familiar with this specific fanfic. However, generally, a fanfic about Loki and Thor might explore their complex relationship in the context of the Marvel universe. If Loki is intersex in this fanfic, it could add an interesting layer to the character's identity and how they interact with Thor.
I really like 'natasha x bucky fanfiction' titled 'The Silent Bond'. It has a lot of action scenes combined with their budding relationship. The author does a great job of showing how their skills complement each other during missions and how that leads to a deeper connection off - mission.
Perhaps Loki is forced to stay in Jotunheim. There could be a powerful spell or curse that binds him to the realm. This could lead to an interesting plot where Thor has to find a way to break the spell and rescue Loki. It would also give Loki a chance to explore his identity while being stuck there.
One common theme could be redemption. After experiencing abuse, Loki might be on a journey to redeem himself or find a way to heal. Another theme could be power dynamics. The abuse might be related to power imbalances between Loki and Thor, which can be explored in different ways. And also, the theme of forgiveness could play a role, either Loki seeking forgiveness from Thor or vice versa.
Well, it can be a way to bring more diversity to the fanfic world. It allows fans to explore different aspects of Loki's character that might not be explored in the official Marvel stories.
His character could also develop in terms of his powers. Maybe the abandonment was related to his latent magical abilities. He could start exploring and mastering his powers more in the fanfic. Thor's presence could either be a hindrance or a help. If it's a help, Thor could encourage Loki to use his powers for good, which would be a big step in Loki's character development.
One common theme is the age - gap dynamic. Given that Peter is much younger than Natasha, it creates an interesting contrast in their relationship. Another theme is mentorship. Natasha can often be portrayed as a mentor figure to Peter, guiding him in the ways of the superhero world.
A common theme is trust. Since Natasha often has a guarded nature, the fanfics usually explore how she gradually trusts the reader. Another theme is mutual understanding. The reader has to understand Natasha's complex past and her role as an agent. Love and attraction are also very common themes as the relationship between the two develops.
