It could be Mat. He has a complex relationship with Mariana in the show, and a pregnancy between them would add a whole new layer of drama to their relationship. They've had their ups and downs, and this would be a major turning point.
One possible storyline could be Mariana dealing with the reactions of her family. The Fosters family is very close - knit, and her pregnancy would likely cause a stir.

I'm not sure specifically which rated M fanfictions about Mariana from 'The Fosters' are popular. However, you could start by looking on fanfiction websites like Archive of Our Own. They usually have a rating system in place, and you can search for 'The Fosters' and then filter for Mariana - centered stories with an M rating. Just be aware that M - rated stories may contain more mature themes such as violence, strong language, or sexual references.
Often, the theme of sisterhood is prominent. They support each other through various challenges in life. And also, the theme of social issues like discrimination in the foster care system. The rated M aspect might come from the complex and sometimes dark portrayals of these issues. For example, when they face unfair treatment from authorities or other kids, the story might get intense and thus be rated M.

To write a great 'The Fosters - Mariana' rated M fanfiction, start with a solid plot idea. Since it's M - rated, you might be dealing with more serious or adult - like themes. Think about how Mariana would react in these situations. Maybe she's facing a moral dilemma that's more complex than what's shown in the show. Use vivid descriptions to bring the story to life, but also be respectful of the source material and the character. Don't make her do things that are completely out of character just for the sake of the M rating. Develop the other characters in the story as well, as they can impact Mariana's journey.
One popular type might be those that focus on their relationship growth during challenging times at home or school. For example, a fanfiction could explore how they support each other through a family crisis. Another could be about their adventures together in a new town, with M - rated elements perhaps including some intense emotional scenes or mild language that adds to the realism of their teenage experiences.

Sure, The Fosters is fictional. It's designed to tell fictional stories and evoke emotions through its fictional characters and their experiences. The show doesn't represent real-life scenarios.
