I'm looking for a fic I read many years ago. It was actually the first (and only at that time) Bruce/Tony fic I read.
Anyway, this fic shows a failed sex scene. Tony almost had a heart attack, because doctors had finally removed the shrapnel but screwed something up in Tony's heart. Bruce, on the other hand, almost Hulk-ed out. There was one moment when their holding hands and each trying desperately to slow their hearbeats and breathing.
Does it ring any bells for anyone? I'd really love to read it again.
