One interesting story could be about how they deal with the joys and fears of impending parenthood. They might have cute moments like shopping for baby clothes together or arguing over baby names in a loving way.
Another aspect could be how their friends and colleagues react to their pregnancy. Some might be overly excited and offer too much advice, while others might be more reserved. This could create some comical or heartwarming situations in the fanfiction.
The main characters are Derek and Meredith. Derek is often portrayed as a loving and sometimes over - protective husband during Meredith's pregnancy. Meredith, on the other hand, is dealing with the physical and emotional changes of being pregnant while also maintaining her career as a doctor.
There might be a fanfiction where Meredith and Derek's baby has a special gift. For example, the baby seems to have an uncanny ability to sense when the patients in the hospital are in distress. The story could follow how Meredith and Derek try to understand this gift and how it affects their lives as parents and doctors. It could also show how the hospital staff reacts to this unique situation.
Another aspect is the character development through these intimate scenes. Their insecurities, desires, and hopes can be more vividly portrayed. For example, Meredith might be shown as more vulnerable or Derek as more protective, which helps to further flesh out their characters in ways that might not be as obvious in the main storyline.
One possible plot could be that Meredith struggles to raise the baby on her own after Derek leaves. She might face financial difficulties and emotional turmoil. But with the support of her friends, she gradually finds the strength to become a great mother.
Another common theme is their professional life. How they balance their relationship with their demanding jobs as doctors. Fanfictions often show them working together on tough cases while also dealing with their personal issues.
One interesting aspect could be how their relationship evolves in the context of this unexpected pregnancy. Maybe they start to communicate more deeply and understand each other on a new level. For example, Derek might become more protective of Stiles, and Stiles could discover a newfound strength within himself as he prepares to become a parent.
Obviously, Derek and Meredith are the main characters. But other characters from their world could also play important roles. For example, Meredith's friends or colleagues at the hospital might be there to support her through the pregnancy. They could offer advice, a shoulder to cry on, or practical help, which would also be an important part of the story.
One common theme is family growth. It shows how Meredith and Derek's family expands with the arrival of the baby and how they adapt to being parents. Another theme is the support from their friends at the hospital. Their colleagues often play important roles in the fanfictions, either by giving advice on parenting or helping out during difficult times.
A good place to start is Archive of Our Own (AO3). There are a lot of fan-written stories about Derek and Meredith. Some might be about their family life, how they deal with work - life balance in the hospital setting, or their friendship with other characters in the show. You can set the filters to exclude any inappropriate content and explore the ones that suit your taste.
There's the 'secret admirer' trope even though they are married. Maybe someone from the hospital has a crush on Derek or Meredith and it causes some jealousy and drama in their marriage. Also, the 'rekindling the romance' trope can be great. After years of being married, they might start to feel like they are losing the spark and then they do something special to bring it back.
