Title: The Sixth of July
Pairing: Clint Barton/Phil Coulson, Steve Rogers/Tony Stark, and the various permutations thereof
Length: 14,206 words
Summary: Clint loves Phil; Phil has a Captain America kink; Tony likes sex. Omelets, Duck Hunt, power outages, and a very happy birthday ensue.
Note: This started as an idea for a PWP about Clint/Phil and Steve/Tony as established couples who spend an evening together. It ended up having even more lead-up sex, lots of fluffy feelings (especially of the C/C variety), exploration of polyamory, and just a bit of Steve hero worship. Despite the fact that it's mostly filthy smut, I'm actually pretty proud of it.
Fic contains various kinks, but everything's consensual; if you're concerned about triggers, everything is listed in the endnotes.
