"Unca Bucky! Unca Bucky!"

Bucky smiled at the sound of his nephew and set down the book he was reading. He looked down from the stool at the kitchen island to see a mop of curls bouncing toward him.

"What's up, squirt?"

"Cho cake?"

Bucky raised an eyebrow, "Not until after lunch, bub. You heard Pops."

"Papa not boss of you,"

To say the man was taken back at the response was an understatement. Peter was always a very polite boy- even at his age of two and a half, he had better manners than most adults Bucky encountered. He felt his eyes widen at the amount of sass in the sentence, "Excuse me, young man?"

"Papa not tha boss," he explained sweetly, and Bucky could immediately tell that these words were not the toddler's own.

"And who might the boss be, then?"

Peter squinted his eyes as he thought about his answer. Bucky wanted to laugh; clearly the kid had been given a script to get a slice of chocolate cake. "I tha boss!" He exclaimed, pointing his chubby little finger at his own chest.

Bucky chuckled then, bending down to pick Peter up and set him on his lap, "You're the boss, huh?"

The toddler nodded furiously, his curls bouncing again, "Choc cake pwease!"

"Hm, no can do, boss," Bucky faked lament, "I'm afraid I lost it."

Peter looked up at his uncle in surprise, "No choc cake?"

"One minute it was there, and then the next it disappeared!"

"Uh-oh," Peter said, not-so-subtly turning his head toward the hallway that led to Steve's bedroom. The door was open just a crack.

Bucky smiled, getting up from his seat, still carrying Peter in his arms, "What a shame, right? I hope you're not too upset with me, munchkin."

"I not Unca Bucky," Peter reassured, "But daddy be sad."

"Daddy?" He questioned smugly as he quietly walked down the small hall, "Why would Daddy be upset? Unless he's the one that put you up to it!" He suddenly jumped through the doorway and, as expected, Tony shrieked from where he was sitting on the floor. Both he and Peter laughed at the brunette, "Busted!"

"Petey, you were doing so well!" Tony complained jokingly.

"Putting your sweet child to do your crimes for you? Shame on you, Stark." 

"Well, no one can resist his puppy eyes. I bet he didn't even unleash them— it's the only explanation as to why you're still alive and I don't have my cake."

"Tony," Bucky sighed, still amused. He set Peter down, who immediately skipped toward his father. "Steve will be right back. Then you can eat lunch and have all the cake in the world."

Tony groaned childishly, "He won't be right back! He's like a middle aged mom! He gets distracted at the store easily." Bucky rolled his eyes but didn't deny it. "Just one slice, Buckaroo?"

"No."

"Half a slice?"

"Tony! Not even Peter is this stubborn!"

"What's that?" Peter asked curiously, sticking a finger in his mouth.

"He doesn't listen. He's being bad."

Peter gasped incredulously, "Daddy bad?"

"No," Tony defended, gently pulling Peter's finger out of his mouth, "Uncle Bucky's just being mean to me."

The latter rolled his eyes again. He reminded himself he loved Tony, no matter how much he could get on his nerves. When Steve first introduced them, he wasn't very fond of the other man. For starters, he was a kid—twenty to Steve and Bucky's twenty-five— and had a newborn. Bucky specifically remembered thinking how irresponsible that was, especially when Tony revealed he and Peter were living in a dorm.

He also thought Tony to be a foul-mouth smartass (which he wasn't completely wrong about, if he were being honest). He had no idea how a sweet and smart man like Steve could like such an arrogant little shit. But then he saw how much Tony would make Steve smile. How gentle he was with his son. How caring he was; always asking Bucky if he needed help with anything whether it was cooking, chores, or help with his prosthetic arm. How passionate or sensitive he could be.

And suddenly, Steve wasn't his only little brother anymore.

But holy shit did Tony take that role seriously, because he sure annoyed him like a sibling, "Please Bucky?" He begged again, giving him a pout and puppy eyes that were usually irresistible, but Bucky had orders to follow.

"Oh, put those away. They'll never be as good as Peter's anyway."

Tony scowled, "Yeah, he really outsold me on that."

"If I give you the leftover ganache, will you finally shut up?"

The younger gasped and smiled brightly, "Yes! I love you!"

"Stevie's gonna kill me," Bucky grumbled, making his way to the kitchen. Tony and Peter followed eagerly. By the time the older man turned around with the bowl in his hand, the two were seated happily on the kitchen island. He gave them each a spoon— and grabbed one for himself—and set the bowl in the middle of the marble.

By the time Steve got home with the rest of the ingredients needed to finish lunch, the bowl of ganache was empty and his three roommates had mouths full of chocolate.

He slumped his shoulders and glared at his best friend, "Are you kidding?"

"One, you never said they couldn't have the icing. And two, you really left me with two pairs of Bambi eyes and expected me to say no?"

"You look so handsome today, babe," Tony flirted, gently nudging Peter next,

"Papa tha hansomest!"

"Yeah, Stevie. You've been working on them calves, haven't you?" Bucky's teased.

"Don't," Steve chuckled, shaking his head in amusement, "I can't believe you guys!"

"Gorgeous, we're still hungry for a real lunch," Tony assured, "A little bowl of frosting isn't gonna spoil anyone's meal."

Steve made his way to him and carefully spun the stool around so that they facing each other. The blonde placed his hands on the marble behind Tony and leaned in close, trapping him, "I specifically told you not to ask for any sweets before I got back,"

"You did? I don't remember that," Tony teased mischievously.

"We'll be discussing this later tonight. I'll make sure you remember next time," Steve said lowly, reveling in the way Tony blushed. He heard Bucky gag dramatically but didn't say anything as he moved to the toddler in his high chair, "And you, mister. You helping daddy be naughty?"

"Daddy saw we get choc cake," Peter explained, "I wanted yummy."

"I know you wanted a yummy, but you know very well you and daddy aren't allowed treats before meals."

"I sowwy Papa," Peter pouted, and there were those sweet eyes Bucky was complaining about earlier.

"Aw, it's okay, honey. You didn't mean it, right? It was daddy who put you up to it." Steve said, nodding his head and smiling when Peter nodded his head too.

"Traitor," Tony muttered, tickling Peter, causing him to squeal loudly.

Steve moved into the kitchen and stopped in front of Bucky with his hands on his hips, "And I thought you were 'mister bulletproof.'"

Bucky groaned, "One of them is adorable and the other is annoying, what did you expect? It was a double attack."

Steve laughed softly and shook his head again, "Get out of the kitchen, you heathens. I expect the lunch plates eaten clean before any of you think about asking for dessert."

Turns out, everyone enjoyed their lunch so much that there was no room for dessert after all.

(Later that night, Tony somehow convinced Steve to have an unhealthy dinner full of takeout and chocolate cake)
