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.
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.
We can come up with a few possible reasons for the crackling noise coming from inside the kitchen wall. First of all, this sound might be caused by the phenomenon of thermal expansion and contraction caused by temperature changes. This sound was usually normal and would not affect the structure of the house. Secondly, this sound could also be caused by the displacement and fracture of the building materials near the wall due to the large temperature difference between day and night. In addition, it was also possible that sparks had appeared on the stainless steel countertop in the kitchen, making crackling sounds. However, these search results did not provide a definite answer, so we are unable to determine the specific reason.
One common theme is family bonding. Lois and Clark are often shown strengthening their relationship as they care for their baby together. Another theme is the balance between their normal lives and their superhero/journalist duties.
One interesting fanfiction could be about their early days in Smallville when Lois first arrives. It might explore how she initially views Clark and his strange behavior. For example, a fanfic could focus on Lois's attempts to uncover Clark's secret before she actually knows he's an alien.
One appropriate topic could be their adventures as reporters. They could be investigating a big story together, facing various challenges and using their skills to uncover the truth.
