"Guess who's pregnant again?" Tony singsongs as he sits down around the lunch fire.
Natasha gives him a level look. "I'm guessing it's not you," she says, cooly.
"Holy crap, Steve," Clint says, looking up as Steve approaches with the baby on his hip. "It's only been a month since you popped that one out. Why the hell would you let Tony get back up in you so soon?"
Steve blushes, but ignores him. He hands the baby to Pepper, who's making grabby hands for him, then sits down next to Tony. "It was an accident," he says, quietly.
"It was me." Tony grins. "I'm super-potent."
"Actually," Bruce says, "It was probably Steve. It's incredibly easy to conceive right after giving birth."
Tony fixes him with a look. "Bruce. Do you or do you not want to marry my sister and come live in my tent."
"Well," Bruce hesitates. "I mean, 'want' is probably a strong word for how I feel about living with you."
Natasha and Clint laugh and pat Bruce on the back while Tony pouts.
"Don't worry, Bruce," Steve says, face feeling mostly back to normal. "I won't let him cancel your wedding festival."
"Yeah, Bruce," Tony agrees, smirking evilly again. "You can still marry my sister. Steve and I will just be there the whole time, commenting on your technique while she's banging you afterward."
"Tony!" Steve says, mortified.
"Don't worry, Steve," Pepper says, still making silly faces for the baby. "In another seven months you'll have three kids to take care of, instead of just two."
"That's it," Tony says. "I changed my mind again. The wedding's off."
"At least Bruce knows what he's getting, moving in with you freaks," Clint says. "Poor Steve came into this whole mess blind."
It's true. Steve didn't realize what he was getting into, that first night, didn't realize the crazy, wonderful family he was becoming part of. It hasn't even been a year since, then, but everything's so much different. He's got a husband now, one he loves with everything he's got, and a baby, too, with one on the way. He's got a sister-in-law he adores, and pretty soon she'll have a bride, too. He's got friends, more than he's ever had before. Altogether, he's got it pretty good.
"You know what," he tells Clint, taking back the baby as Pepper hands him over. "I think it all turned out pretty great, anyway."
