In some fanfictions, a great romantic scene is when Clark finally reveals his true identity to Lois. It's a moment full of trust and vulnerability. Lois's reaction, whether it's shock at first and then acceptance and love, can be very touching. They might share an intense and passionate kiss afterwards, sealing their new level of connection.
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.
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.
