I'm looking for a fic I've read some time ago, but I don't remember the title, nor the author. I can't remember either if it is PG or Nfic, and I don't know if it is a short or a long story (although I think it is long, but I'm not sure).
What I do remember is that:
Clark and Lois are married for quite some time, and Clark had become a famous writer. He had to go to a book convention that is not in Metropolis to make the promotion of his latest book, and so he leaves for a few days. Lois doesn't want Clark to know, but she had started to write books too (romance novel with hot scenes) under a pseudonym, and it is a success. She had to go to the convention too, so she put a disguise so no one recognize her. She tries to avoid Clark in the hotel where the convention takes place, but they meet, and Clark doesn't seem to be recognizing Lois, but he's flirting with her, so Lois thinks that her husband is about to cheat on her.
Ring any bells?
