Their relationship might develop through shared experiences. For example, when they are both investigating a mystery in Metropolis. Clark uses his super - powers subtly to help Lois get to the bottom of the story, and in the process, they grow closer. As they face danger together, they start to rely on each other more and more, which deepens their connection.
One interesting plot could be Clark and Lois working together to expose a conspiracy in Gotham that involves both Superman and Batman. Maybe they discover that a powerful criminal organization is trying to pit the two heroes against each other for their own gain. They use Lois' investigative skills and Clark's powers to gather evidence and try to bring peace between the two vigilantes.
Well, it's inappropriate. Fanfiction has the potential to be a great way to expand on a story or characters, but when it involves sexual content related to characters like Clark and Lois, it crosses a line. It's better to create fanfiction that focuses on their heroic deeds, their love in a more chaste way, or their development within the story's universe without getting into sexual territory.
One possible fanfiction could be that Clark and Lois are in the middle of a dangerous situation in Smallville. Maybe there's a meteor - related disaster about to happen. In the heat of the moment, Clark realizes his true feelings for Lois and they share a passionate kiss, which gives Clark the extra motivation to save the town.
Their relationship can be shown as even more loving and protective. Superman would be constantly worried about Lois and the baby, and Lois would appreciate his care while also being her strong - willed self. For instance, he might fly her to her doctor's appointments super - fast to avoid traffic.
Clark's reaction would be complex. At first, he might be in shock. But then, he'd feel a deep sense of joy and responsibility. He would do everything he could to support Lois. He'd use his powers subtly to make her life easier during the pregnancy, like getting things she needs quickly or protecting her from any physical harm. He'd also be thinking about how to raise a child with his special abilities in a world that doesn't know about his true self.
