I haven't come across a Sasha x Connie pregnancy fanfic myself. However, the existence of such a fanfic depends on the creativity of the fans within the relevant fandom. Some fanfic writers might explore this kind of relationship and plot development, but it could also be that not many have delved into this particular scenario yet. You can check fan - made communities and forums related to the source material to see if anyone has written or knows about it.
One common theme is friendship. Their bond as comrades is often explored, like how they support each other during tough times in their battles. Another theme could be growth. Writers might show how Connie and Sasha grow as individuals while also being friends.
Growth is another theme. Fanfics may show Sasha and Connie growing as individuals within the context of their relationship. They learn from each other, become more mature, and their relationship evolves as they develop new skills and perspectives.
Friendship is a very common theme. Writers often explore how Connie and Sasha support each other through thick and thin. Their different personalities, Connie's more reserved nature and Sasha's boldness, make for interesting dynamics in their friendship.
Sure. There are some really interesting Connie Sasha fanfics on Archive of Our Own. You can search by tags like 'Connie' and 'Sasha' to find ones that focus on their relationship, whether it's a friendship - based story where they go through adventures together in the world they live in, or a story that explores their backstories and how they came to be the characters we know.
There are quite a few. For example, 'Connie and Sasha: A New Chapter' which delves into their relationship after a major event in their story world. It has great character development and explores their emotional connection. Then there's 'Sasha's Secret Admirer, Connie' which is a more light - hearted take on their relationship, with Connie trying to woo Sasha in his own clumsy but endearing way.
There's also 'Connie and Sasha's Day Out'. This fanfiction focuses on a normal day in their lives, but it has a lot of cute interactions between them, like when they go shopping and Sasha tries to convince Connie to buy some strange items. It really delves into their personalities and how well they complement each other.
One possible plot could be that Sasha and Connie have an unexpected pregnancy. They then have to deal with the reactions of their friends and family. Maybe they face challenges like deciding whether to keep the baby, and how it will affect their lives as young people in their world.
Since I haven't actually read one, it's hard to say for sure. But generally in a 'lemon' fanfic, there might be some romantic or more adult - themed elements. However, in a Connie x Sasha one, it could also include their unique personalities from the original source material, like Connie's determination and Sasha's love for food being incorporated into the story.
