One possible plot could be that Alex and Justin accidentally cast a spell that results in one of them becoming pregnant in a magical way. Maybe they were trying to solve a problem for a friend but something went wrong with the spellcasting.
Perhaps in the fanfiction, there's a prophecy that states for a powerful magical event to occur, a Russo must become pregnant. Alex and Justin get caught up in this prophecy and have to figure out how to handle it while keeping it a secret from their family at first. They would face challenges like how to balance their normal lives, school, and this new unexpected situation.
Another idea could be that they find a magical object that when touched, causes a pregnancy - like a cursed item. Alex and Justin then have to search for a way to reverse it before it's too late. Along the way, they learn more about their family's magic history and the true power of their own magic.
The main characters are clearly Alex and Justin Russo. Alex is known for her impulsive and fun - loving nature in the original show, and Justin is the more studious and rule - following sibling. In this fanfiction, their personalities would likely be put to the test with the unexpected situation of a pregnancy.
One common theme is family. Since they are siblings, many fanfics explore their relationship, like how they support or annoy each other. Another theme is magic. Their magical abilities are often central to the plot, such as using magic to solve problems or get into trouble.
Perhaps they could be in a world where magic is involved. The pregnancy could have some magical implications, like the baby having special powers. They then have to protect the unborn child from those who might want to use its powers for evil.
One great 'Alex and Justin Russo' fanfiction could be 'The Magical Bond'. It focuses on their relationship growth while dealing with magical challenges. Another one might be 'Russo Siblings' Adventure' which takes them on a new magical quest together. There's also 'Alex and Justin: Unseen Moments' that delves into some unshown moments between them in the magical world.
There's also 'Alex and Justin: A New Bond'. This fanfic focuses on a time - travel scenario where Alex and Justin end up in a different era of the wizarding world. They have to rely on their sibling bond and magic skills to find their way back. It has a great blend of adventure and family dynamics.
You can try fanfiction websites like FanFiction.net. It has a large collection of various fanfictions, including those about Alex and Justin Russo. Another option is Archive of Our Own (AO3), which also has a great selection of fan - created works related to different shows and characters.
One of the essential elements is the exploration of their personalities. Alex is known for her impulsiveness and Justin for his studiousness. A great fanfic will play on these traits. Another aspect is the family dynamic. Since they are part of the Russo family, how their parents and other family members interact with them can add depth. And of course, the magic system needs to be consistent. If it's too chaotic or doesn't follow any rules, it can make the fanfic less enjoyable.
Often, themes of magic and the Russo family's wizardry might be incorporated. For example, their magical powers could play a role in the story, either in bringing them closer or creating some sort of conflict within the 'lemon' - themed plot. Another theme could be growing up and dealing with the changes that come with it, as they both are in different stages of adolescence in the show and fanfics could expand on that in a more romantic or mature way.
One idea could be that Alex Russo uses her magic to help Harry Potter in a wizarding tournament. Maybe she disguises herself as a Hogwarts student and uses her unique magic skills, like her ability to freeze time briefly, to give Harry an edge in a difficult task.
I've also heard of 'Alex and Justin: The Magical Quest'. It takes the two on a quest that not only tests their magical abilities but also their bond as siblings. The story is filled with action and some heart - warming moments as they support each other through tough times.
