[Captain America/Avengers] The Origin of Humanity on Marvel's Continent (Parody)

A creation myth about the origins of humanity in the Marvel universe. Pairings include Steve/Bucky, Bucky/Steve, Thor/Loki, Tony/Steve, and Natasha/Clint, Natasha/Clint. A nonsense parody that will probably definitely be out of character. The idea came from a parody I posted on LOFTER. A reader commented that Bucky was born from a bun, which suddenly made me think of all those creation myths where the ancestors are born after someone eats a bird's egg, a fruit, a star, an animal's saliva from a sacred totem, or some other thing. Then I got bitten by the idea bug. Theme:
