It could also be strained. There might be some jealousy or differences in opinion on how to handle the situation. For example, one of them might want to be more involved with the girl during the pregnancy while the other feels left out, which could cause some tension between them.
Well, at first, it could be a bit rocky. But as they realize the importance of the situation and the girl's well - being, they could put aside their differences. They might have long talks about their friendship, the girl, and the future of the child. Through these conversations, they could reaffirm their friendship and work together for the good of all involved.
In the fanfiction, it could be that there was some sort of mission or adventure that brought the three together. During that time, the relationship developed and the girl got pregnant. Steve and Bucky might then use their skills and resources to protect the girl and prepare for the baby. They could have to deal with enemies who might want to harm the girl because of the baby or their relationship.
At first, it might be a bit rocky. Tony, being used to his own space, might feel smothered by Steve and Bucky's over - protectiveness. But as time goes on, he'll start to see their good intentions. Steve's moral compass will inspire Tony to be a better person, and Bucky's loyalty will make Tony feel secure.

There's also 'Forging New Bonds'. This fanfic focuses on the post - conflict relationship between the three. It explores how they start to understand and accept each other better. The writing style is quite vivid, making it easy to picture the scenes in your head.
One common theme is loyalty. Steve and Bucky have a deep loyalty to each other that is often explored. For example, in many fics, Bucky will go to great lengths to protect Steve and vice versa.
I really like 'Bucky's Redemption'. In this fanfic, Bucky is on a journey to fully come to terms with his past actions while Steve is there to support him every step of the way. It shows their loyalty to each other in a very touching way. There are some intense emotional moments as Bucky struggles with his guilt and Steve tries to pull him out of the darkness.
Typically, Steve and Bucky lemon fanfiction often emphasizes their deep emotional connection. It might show their loyalty to each other in different situations. For example, in some fics, they support each other through post - war traumas.
One possible reason could be Steve's strong sense of loyalty to Bucky. Maybe he feels that he owes Bucky so much after all they've been through. He might be so focused on helping Bucky or being there for him that he unconsciously ignores Tony.
Yes, Bucky was Steve's best friend in the comics. They had a deep and long-lasting bond.
On the other hand, Steve might be more understanding than expected. He knows about Bucky's past traumas and could suspect that something else is at play. So, instead of immediately resisting, he might play along for a while, waiting for the right moment to figure out what's really going on and how to help Bucky.
No, they didn't. Their relationship in the comics was more of a deep friendship and comradeship.
