Somebody should write a fic were Clark catches a cold and Lois is nursing him back to health or something like that. I would just love it
It's been a very long time since I read it, but I think you might find elements of what you're looking for in Yvonne Connell's Heliophobia, Sunshine.
Clark doesn't exactly have a cold, but he is sick, and I seem to remember some Lois nursing in the mix.
