They've been called up for a reconnaissance mission in undercover, but everyone knows Captain Marvel SUCKS at it because he always shows up with a huge trench coat, sunglasses, a mysterious hat and his bright red suit would still be pocking up somewhere

But they really need Marvel to do it, and he's like "don't worry! This time I can really pull it off, okay? I promise"

But Mary is there, Mary listens and she smiles like a little devil

"The problem is that Cap is terrible at dressing up, he's such a workaholic that he doesn't even know how to dress without the hero vibes anymore. But that's okay! Mister Batman, can we have some money? I promise I'll make Cap look unrecognizable for this mission! There's just nothing really suitable in his wardrobe."

And Batman just says, "Okay, I'll send you enough money. Please, Miss Marvel, don't let him come in his suit again…"

And then they plan to have Marvel show up at the watchtower before the mission, because they need to make sure he's actually dressed for it. And well, it ends up with Guy Gardner setting off the alarms because of an intruder, but when they go see him, it's Marvel who's looking like the most dad-like guy ever.

flannel shirt, high shorts, tacky belt, a FAN PACK!!! and sneakers

But like, he looks so normal. Seriously. His hair is different, he even has some makeup on to fake frown lines and dark circles on his face. He looks very human, very civil, and he's so dad-coded. Captain Marvel is already dad-coded, but like, a super dad. This dad in front of them is just a tired and proud father with tired eyes but a smile that shows how happy he is in this role.

Mary comes next, she is also dressed as a teenager, and she is smiling so brightly that the stars are jealous.

She is very proud and thanks them so much for letting her do this. She always wanted to pick out Cap's clothes because he is terrible at it and she loved playing dress up with him for a while.

The undecover goes well, it's in a mall and no one even blinks at the dad!cap and daughter, both super casual and happy and normal

Later, Batman finds a video from a security camera, and it's 4 in the morning in a clothing store, Mary and Marvel are there and it really looks like they're playing dress up. Mary picks out things for him, he tries them on and goes to show them to her, he makes some jokes, parades, laughs a lot and everything

Bruce finds this father and daughter moment (because they really don't know they're brother and sister) really cute and it inspires him to ask his daughters to go shopping with him soon

Well, he deletes the videos for the heroes' safety, but he has a backup because he wants to show it to other league mates too. Plus, information.

Steve watches him, how he tries to grab at Peter to get him to stop talking, "kid, shut up or I'm gonna piss myself—seriously!", but Peter is as fixated on his joke as he is mischievous, delighting in the unencumbered laughter he's pulling from Tony.

This is Steve's favourite joke. Not that he heard it considering he just walked in, or could understand it if he did (Tony keeps chuckling over the word 'tachyons'), but anything that makes his boyfriend light up like a million lumens is positively the greatest thing in the world.

He wants this. Wants Tony this happy, Peter this excited, wants a family. This family.

He tries to say as much.

"I wish I could get you pregnant."

The entire room freezes. Steve is probably the most shocked of all by his own words, but Peter and Tony pause their chuckling and immediately set their laser focus on him.

"I—I misspoke—"

It's too late to explain himself. Peter and Tony look at each other, and in the next moment they're both falling over each other in laughter.

"I'm actually gonna piss—"

Peter cuts Tony off with such a raucous guffaw that Steve's concerned the boy is about the cough up a lung.

Tony curls into a little ball on the floor with his head buried in his knees, entire body shaking with laughter so hard that he's gone silent. Peter falls to the ground as well, forehead pressing against the concrete and smacking his hand against the flat surface.

"What a knee slapper—"

Peter starts giggling even harder at his own words that Steve can't help but join in on the ridiculousness.

The red flush of Peter's face becomes as hilarious as it is concerning, and Steve's sure him and Peter both could colour match a ripe tomato. If Tony's quiet is any indication, he's probably blue from lack of oxygen. All the laughter is coming out, none of the air in. If Steve wasn't so consumed with adoration and joy he'd be concerned.

Once Tony is able to curb his suffocation he blooms like a rose; opening up and falling onto his back, limbs splaying out as remnants of laughter slip from his pink petal lips.

"Ah, you amuse me Rogers."Steve can't help but grin back at the man, elated and proud.

"Well, at least I'm capable of that."

Tony giggles softly, unerasable smile soaking Steve in its warmth. He reaches a hand out for Steve to help him up.

"I wouldn't count yourself out so fast. I'd like to try this whole impregnation thing. Maybe if we keep practicing it'll take," Tony conspires, instead using Steve's unsuspecting hand to tug him down and on top of him on the floor.

"Oof—oh," the large man catches himself with his forearms before he can crush the body under him, hovering there as Tony leans up to rub their noses together.

Not that he'd say it out loud, but Tony really reminds him of a cat sometimes. Prickly, beautiful, and the sweetest little thing when they actually like you. Steve smiles privately at the thought and the affectionate touch.

"Ew, PDA!"Peter shouts in offense.

Steve tries to move back but Tony grabs the back of his neck, pulling him into a kiss that Steve falls all too easily into.

"Ugh, you guys are so gross. Romance ruins everything."

The sound of Peter's fading footsteps plays in the background of Steve's mind, too focused on the pleasant hand running through his hair and tongue licking into his mouth.

"FRIDAY, lockdown the lab," Tony whispers against his lips.

"On it boss."

Steve pulls back far enough to raise an eyebrow.

"What? You're the one who wants to get me pregnant."

"I didn't mean right now—no, I didn't mean it at all, obviously. That's impossible. I just..."

"Well I mean right now. Maybe we'll revisit the whole kids thing when we're sure I can't have my own. First we gotta test that theory though," he smirks and pulls Steve back into a kiss.

The team of Spidey's fathers! I'm sorry but I see them too much like that. I would have loved that in the MCU we got more scene with Steve and Peter :'(.
