I know how busy you must be, but if you get the chance or if it inspires you, I'd love to see poly relationship headcanons with the reader and two characters you wouldn't normally see together.
Being in a Polyamorous Relationship with Sam Wilson and Maria Hill would include:
A hell of a lot of snark directed at other people
You and Sam being overly affectionate to Maria so she gets grossed out and tries to shake you off
Sam loving when the two of you sleep curled up against his chest
Heated make-out sessions
Having to drag Maria home from work
Sam reassuring you when she randomly goes missing because of work
Sam easily telling you both he loves you
Getting an ‘I guess’ from Maria if you ask her
Maria is the boss
Her rolling her eyes when you and Sam are being silly together
But her joining in anyway
Them having long conversations in jargon sometimes
Natasha and Steve being like your new in-laws
Maria enjoying telling the two of you want to do in the bedroom
Testing your boundaries
Waking up to an empty bed
Picking on Bucky and Steve together
Always having breakfast together when they aren’t out on a mission
Patching them up
Maria looking at you both like she wants to eat you
