The other story I never read, but read the summary, and I thought I had marked it, but obviously didn't since I can't find it in my bookmarks.
The description on A03 was Tony and Steve had been captured and were being held in a cave, I think, and Steve was the injured one, and Tony was the BAMF/strong/supportive one during the kidnapping.
I appreciate the help in finding these stories.
Edit: First story found while going through A03 It's Supernanny by ashinan.
Still looking for the second story.
