These two are long, but they're a fantastic read. They present a side of Steve Rogers you may never have seen before. The stories are by charmingcontender and are found at Archive of Our Own. Read Arsonist's Lullably first because the second story takes this one, makes a few changes, and expands itself around it, timewise. (And yes, that's how its spelled.) A Flaw in My Code just blew me away. They are Steve/Bucky and Steve/Bucky/Natasha with some early WS-young Nat that will break your heart. Hope you enjoy them.

(I'm going through my stuff so I may find some more to recommend to you later.)
