There's a story I'm hoping y'all will be able to help me find, even though I don't have a lot of details.
It was a fairly long story, and I only got to read the first couple chapters. I think it was posted here... 8-15 years ago?
It starts off with a man talking with his wife about his bedwetting. She has been supportive, but he asks her to punish him when he wakes up wet, saying he believes it will help him overcome it. She agrees, and quickly adapted to being in charge of punishing him.
Unfortunately, that's about as far as I read in the story.
