I remember quite a bit about this multi-part (I think it was close to 30 connected short stories) series that I'm certain was posted on AO3, but I can't find it in my bookmarks, so I was hoping that someone would know it offhand.
In this world, BDSM is the norm and everyone is a sub or a dom (though Tony, being Tony, is a switch, I believe, though I think he subs to Pepper). I think the primary pairing was Clint/Coulson (ironically, I can't remember who was Dom/sub, though I'm assuming that Coulson was the Dom), though as the series progressed, it explored many other relationships: Fury/Natasha - Dom!Fury and sub!Natasha), Steve/Bucky (Dom!Steve and sub!Bucky - that was a really heartwrenching part of the series and also the last couple of parts I saw posted). I don't remember with whom, if anyone, Bruce was paired, though it might have been Bruce/Betty.
Another plotline that was explored was that Justin Hammer was a sub who'd been misclassified (and abused) by his father into being a Dom. His crimes were actually somewhat excused when it was discovered.
Any and all help would be greatly appreciated! Thank you very much!
Mods: I didn't see a "Natasha/Fury" tag, please and thank you!
