It's my birthday soon, so I wanted to write a fic where Tony is as childish and enthusiastic about his as I am.

:D Enjoy!

"I want a dog for my birthday!"

Steve blinked and yawned loudly, reluctantly pulling his eyes away from the newspaper before him to look up at Tony, who was way too perky for six o'clock in the morning. Steve gave one look at Tony's expectant, happy face, and groaned.

This was going to be one hell of a fight.

After a few more gulps of coffee and yawns, Steve looked up at Tony (who was practically humming with energy, bouncing on the balls of his feet and a smile spread across his face, waiting) and Steve sighed, loudly.

"No."

Tony looked crestfallen for a moment before pulling his lips together in a pout. "But, Steve," he whined, crossing his arms childishly, "All the other kids have one!"

Steve would've laughed if it hadn't been so early in the morning. Instead, he just settled for sighing, wondering why out of all the people in the world he fell in love with such a brilliant, overgrown five year old.

"No, Tony. We're not nearly here enough to give a dog the proper care it needs. Who do you expect to take care of it when we're in Europe attending press conferences? JARVIS?"

Tony paused for a minute, then looked hopeful. "I could program him to-"

Steve rubbed the back of hands over his face and tried to be patient. "Tony, no, I'm sorry. We can't get a dog. For heaven's sake, our room in on the thirtieth floor! When it needed to go outside at night, are you going to walk down thirty flights of stairs?"

That was the exactly wrong thing to say, and Steve knew it as soon as Tony lit up like a string of Christmas lights. The man seemed on the verge of squealing in delight, and even Steve, in his half-asleep stupor, found it very cute that Tony was getting this worked up over a dog.

(No matter how much Tony denied it, he loved animals.)

(It was another thing Steve loved about him, his hidden weaknesses.)

"Well, for a long time now, I've been wanting to renovate a balcony…I could make it into a patio garden! With real grass and trees and stuff and the puppy could go play there when we couldn't take it for walks! I'd feed it and walk it and it could sleep in my bed with me at night-"

Steve snorted. "There's no room in our bed for an animal. You take up too much space."

Tony looked temporarily insulted. "Like you can talk, Mr. I'm ninety-eight percent muscle mass. Anyway! Fine, I'll build it a special super-awesome pet bed with interactive holograms and everything! Please, Steve, pleeaaaassseeeee?"

It was the last long, overly-enunciated please that did Steve in. He started laughing, a deep laugh that budded from inside his chest and left him grinning. "Tony, you are such a little kid."

"Am not."

"Are too."

"Are not!"

"Are too-"

"Sirs, for the safety of yourself and others, I respectfully ask you quit childishly bickering or I'm going to set off the fire sprinklers."

Steve jumped about five feet in the air out of his chair at the table when JARVIS came over the intercom. He wasn't used to the whole my-boyfriend-has-a-robot-that-talks-from-the-ceiling thing, not just yet.

(He figured he'd have all the time in the world to adapt, though, so he wasn't worried.)

Tony smirked. "Hey, JARVIS, you agree that because I am a wonderful, devilishly handsome, brilliant upstanding member of society I should get to have a dog for my birthday, right?"

"Well, actually, sir-"

Tony growled then, a low sound pooling in his throat, looking up at the ceiling in a glare. "I swear, JARVIS, if you disagree with me, I'm going to upload porn of myself to your files and make you watch it forever on repeat."

JARVIS made a horrified groaning sound and Steve looked terrified. "You- you have porn? Of yourself?"

Tony took a couple steps closer to Steve, elbowing him and whispering breathlessly in his ear, "Not yet, I don't…but you could help me make some."

Steve turned bright red and hissed, "JARVIS is listening!"

Tony just smiled and ghosted his lips over Steve's ear, nibbling a little, teasing, causing Steve to inhale sharply and hold his breath. Steve hated that Tony could do this to him, with just a few little touches, make him into some puddle of desire.

Tony knew what he could do, too, and used it to his advantage. Steve was too preoccupied with Tony's lips on his throat to notice what Tony was trying to do before he drew back, nestling his nose into Steve's hair and whispered, "Can I have a dog now?"

Steve grumbled. "No, Tony," he finally said, after several more kisses made their way down his throat. "We're just too busy."

Tony went back to pouting but began to fiddle with the button's on Steve's civilian clothes. "JARVIS agrees that I should get one, though," he reasoned, ignoring the AI'S indignant snort, "And he's a robot. You wouldn't want to upset the resident robot, would you, Cap?"

"I don't think JARVIS is going to kill me in my sleep." (He hoped.) JARVIS made a sort of snorting sound again.

Tony cocked an eyebrow but didn't say anything, leaning forward over Steve's back so he could run a hand up his thigh. "You're sure?" He asked, eyes dark and twinkling, when he left a hand resting at the very top of Steve's thigh, watching the other man squirm.

Steve cleared his throat and tried to speak without his voice quivering. He was really, really, really turned on. Which made this difficult.

"I'm sure."

Steve thought he heard Tony grumble a soft damn before he pulled away, making to leave the kitchen. "Fine! You're no fun anyway," he heard Tony mutter before he stalked out into the hallway.

With Tony gone, and Steve painfully aroused, he looked at his (now soggy) cornflakes in disdain and decided to try and focus on his newspaper, like he had been calmly reading before Tony came in and rudely interrupted.

He flipped through a couple pages, skimming the articles, when he sees a picture of a bunny on one of the pages, being held by a dark-haired little boy.

"Huh," he said, staring at the page, as an idea started to form in the back of his mind.

"JARVIS?" Steve asked hesitantly, looking up at the ceiling and speaking in what he hoped the AI perceived as a polite. (Tony designed him, after all, so while that meant it wasn't likely that JARVIS would turn evil and brutally kill him, it was always a possibility.)

(He blamed Bruce for showing his some video clip about an evil robot named Glados.)

"Mr. Rogers, sir," JARVIS answered, tone clipped and professional like a real butler's would be. "Do you require assistance?"

"Tony didn't…didn't load inappropriate things into your files, did he?" Steve asked, fiddling with the bag in his hands, pausing to reach in and stroke the animal when the bag quivered.

The AI laughed, an action Steve thought was strange, coming from a robot. (Sometime, Steve almost forgot JARVIS wasn't a real person, with the way he reacted to things. Tony truly was a brilliant programmer.)

"No, sir. You two haven't had time to take any yet," JARVIS replied, sounding slightly amused.

The tips of Steve's ears turned red again. "You don't…you don't watch us all the time, do you, JARVIS?"

JARVIS only beeped in amusement. It figures that Tony's robots would be perverts.

"Anyway, where is Tony? I've got something for him."

"He's down in the lab, sir. And I sincerely hope you didn't get him a puppy."

It was Steve's turn to laugh. "Don't worry, JARVIS. I'm not stupid."

Steve stepped into the elevator and JARVIS automatically selected the floor number for Tony's lab. As the doors dinged open onto the bottom floor, Steve's ears were roughly assaulted by what he could only describe as a chainsaw accompanied by bad drumming and yelling.

"JARVIS, please," he begged to the AI. JARVIS beeped in amusement again before changing Tony's music to a kid's soundtrack.

Steve grinned at Tony's exasperated, "Hey!" and whispered a thank-you to JARVIS, before stepping to the lab to see a very annoyed Tony fiddling with his stereo, muttering something about choking motherboards and stupid robots.

"Happy birthday to you."

Tony started at the sound of Steve's voice, before turning around in excitement. Upon seeing the bag in Steve's hands, he put on a mock frown, saying, "Aww, I was hoping it was going to be you all wrapped up. Preferably naked, also."

Steve didn't even bother to look horrified, just sighed and handed his crude boyfriend the bag. "Happy birthday."

Tony looked up at Steve, his face soft. "My birthday isn't until next week. I didn't mean to pressure you into getting me something- unless, of course, that something is a dog, then I totally did want to pressure you- but seriously, you didn't have to get me anything."

Steve smiled as Tony jumped again when the bag rustled.

"Look inside."

Tony did as he was instructed, looking in and then taking a deep breath. After a minute of silence, he looked back up at Steve, grinning so wide it looked like his face would split in half.

"You got me a bunny!" Steve was not prepared for the impact when Tony through himself at him, wrapping his arms around Steve and earnestly nuzzling into his throat. "I can't believe this! I love it! Thank you thank you thank you! It's not exactly a puppy but its' .fluffy! How did you know I loved bunnies!"

Steve laughed and put his arms around Tony, drawing him in closer. "Wild guess. You're welcome. Even if you are an overgrown child."

Tony purred contentedly in Steve's arms, pressing his lips to the soft skin of Steve's throat. "I love you, you know," he whispered, leaving a tender kiss against the pale skin.

Steve just buried his face his Tony's hair, the words not sinking in.

They stood like that for a few more seconds, before Tony jumped back like he'd been shocked with a wide-eyed look, mumbling something about "Bunnies! Right! I should take it out of the bag. I think we should name it Mackenzie. It is a her, right? Do you like that name? I like that name. It is very fitting for a bunny."

Steve raised an eyebrow. "Mackenzie? Really?"

Tony looked put out. "Well, what do you suggest, then? Lassie?"

"Well.."

Tony shook his head, looking over at the black bunny sitting atop his messy workstation. Picking her up, he cradled her to his face, stroking her soft fur.

"We can name her Mackenzlie! That's fair, right? A combination of the two? Oh, thank you, Steve, I love her!"

Steve barely caught the last words as Tony was all but sprinting out of the labs, shouting something over his shoulder about "proper materials for a rabbit mansion."

He laughed, looking at the whirlwhind Tony had left as he'd riflied through all his tools. "So, appearantly now I own a bunny named Mackenzlie," he said conversationally to the ceiling, leaning up against one of Tony's many workbenches.

"A good choice, Mr. Rogers. I doubt he can cause too much trouble with a small, furry rodent." Right after the AI had finished speaking, the sound of an explosion came from down the hallway, followed by a muffled shout of "I'm okay!"

Steve just shook his head.

"You know, on second thought, you should've gotten him a cat."

"Why do you say that?" Steve questioned, curiously looking up at the ceiling. "He may or may not have just violently combusted our bunny. I don't think giving him something with claws would be healthy."

"But cats are such independent, arrogant, narcissistic creatures. Tony and cats would get on brilliantly."

Steve smiled. He really liked JARVIS, despite him being a robot. "I take it you aren't a cat robot?"

"Affirmative."

After their brief conversation, there is another explosion, and Tony skitters back down the hallway, clutching Mackenzlie in one hand and a bunch of assorted metals and woods in the other, hands covered in soot. He was also missing his eyebrows, but Steve just elects not to ask.

"Look! She's okay! I know you probably though I exploded her but I didn't. It was close but hey almost only counts when you're using grenades, right? Those were much lower grade explosives. Hey, you don't think I should still build the garden balcony, do you? I think I will so Mackenzlie can get exercise!"

Tony dithered on, running here and running there, hastily assembling something Steve hoped was a house and not a bunny-sized torture chamber. It was leaning either way at this point.

Tony kept babbling but Steve didn't mind. He loved to hear Tony talk, the man had such a way with words and he loved to watch Tony's hands flying this way and that when he got really in-depth in a subject or when he was talking very, very fast because he was nervous.

So Steve watched, and Tony talked and doted on his bunny, and Steve thought it was a wonderful pre-birthday.

It doesn't hit him why Tony was being so nervous until late that night, when they're tangled up together and in the bed sheets, one breathing mass of person. Tony was exhausted, from all his bunny-house-torture-chamber-thing building, and Steve finally convinced him to lie down and sleep for once, after they positioned Mackenzlie's hutch in the corner of their room.

Which, of course, resulted in Tony suggesting they make a porno, and Steve just laughing.

(There isn't any camera, but there probably doesn't need to be. He gave the ceiling a thumbs up during the middle of all of it and he swore he heard JARVIS laugh.)

So then, absently, as he ghosts his fingertips through Tony's hair and stifles yawns of his own, staring at the bright light of Tony's arc reactor, he feels a rush of something that he can't quite name, and he remembers.

I love you, you know.

It's weird, Steve thinks, that such domestic words came from the mouth such a widly undomesticated man.

(Steve doesn't mind, though, and just presses his face against Tony's and breathes, "I love you, too.")

(He doesn't notice the smile on Tony's face.)

Thanks for reading!

This is going to be a collection of fluffy Steve/Tony drabbles (like this. This was supposed to be a drabble but...it kinda got away from me.) However, this certain one will most likely have two parts, since I really want to write a story about Mackenzlie the Bunny in a party hat.

Sorry for the overlyexcited!Tony. I know he's very snarky and all normally, but in my headcanon I just imagine him being really excited for birthdays. They're awesome, though, really!

Also, in my own personal little headcanon, these drabbles are basically just fluffy filler stories between Lawnchairs After Dark and the sequel, which is coming soon, I promise.

Again, thanks for reading!
