"The first time Steve meets Toni is about a week after he wakes up."

(Just Pre Heroic Age) - The Avengers aren't quite back together yet, things are still a little rocky between Tony Stark and Commander Rogers, and Tony's slaving away at Stark Resiliant, trying to make a fortune again to fund everyone's superhero habit, and be on his best behavior for Steve, when Maria Hill calls him with a problem... an unidentified Iron Man suit has appeared in New York City. But it's not talking.

From a prompt on Avengerkink. Thanks to a magical spell by invading aliens from another realm, Tony Stark becomes a woman...for three months. Obviously there's no way he's not going to take his new body for a test drive. And who better to help him with it that our very own Captain America, Steve Rogers, the straighter-than-a-ruler guy he's been falling in love with totally against his will and who's finally noticing him now...

Antonia Carter Stark takes no shit and no prisoners.

Stephanie Rogers isn't happy to be in the 21st century, but she's even less thrilled to be on a team with Antonia Stark who seems as spoiled and self-centered as people come. She and Tony do their best to ignore each other, until their mutual insomnia (read: nightmares) causes them to bond over the new American pastime: late night television watching.
