The first fic I read several month ago, when I first watched all the movies and then started reading the fic. Bruce Hulked out at the Tower, and while everyone else was a little freaked out, Tony and Hulk went out onto the roof to watch either the sun set or rise. They were sitting on the edge of the roof with their feet dangling.
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.http://archiveofourown.org/works/440288
Still looking for the second story.
