So, literally years and years ago, I read a fic which I think was pretty short, so might even have been a comment!fic, where Sam and Dean are out in a field somewhere, playing catch with a baseball or something, and Sam throws it too hard and it hits Dean and stops his heart... Sam has to do CPR to save Dean...

Does this ring any bells with anyone? Or anyone have any good CPR fics, preferably with Dean receiving?

Thanks all! :)

(I'm not sure what tags to use, so have just gone with a generic hurt!dean tag... if there are any other applicable ones, I can add them...)
