“Look what we did,” Steve’s voice broke, giving him a watery smile returning his eyes to the baby in his arms. “Hi Peter. You are so perfect.”“We’ve been waiting for you.” Tony said softly, running a finger down his cheek.They cooed at the pup for another few seconds before a nurse took him to get cleaned up. Tony looked down at his omega, who was still crying quietly with a sweet smile on his face.“You did it, baby. You did so good.” he bent down so he could kiss Steve softly. “He’s so, so perfect.”
Note
I'm so sorry to make you guys wait so long! I've been so busy and have had such bad writer's block. Here it finally is, Peter is here!

 It did go just as smoothly as the rest of the pregnancy, thankfully. Fourteen hours of labor later and they had their beautiful baby boy. Steve was a trooper through the whole thing, clearly in pain and groaning every few minutes, he was still in a good mood and laughing and smiling at his mate the rest of the time. 

 

Tony didn’t think he would’ve handled pregnancy that well at all. He didn’t know how he got so lucky finding his perfect omega. When the baby, with a tuft of brown hair, was finally out he was placed in Steve’s arms. Steve was crying, tears running down his face as he looked into Peter’s blue eyes with so much love of his own. Though he had a feeling they would change into brown like Tony’s. He looked up at the brunette, who had one of his hands in Steve’s hair and the other over his mouth. Tony also had tears gathering in his eyes, and when they met Steve’s, the blonde reached up to pull his mate down into a soft kiss before Tony leaned his head on Steve’s.

 

“Look what we did,” Steve’s voice broke, giving him a watery smile returning his eyes to the baby in his arms. “Hi Peter. You are so perfect.” 

 

“We’ve been waiting for you.” Tony said softly, running a finger down his cheek. 

 

They cooed at the pup for another few seconds before a nurse took him to get cleaned up. Tony looked down at his omega, who was still crying quietly with a sweet smile on his face.

 

“You did it, baby. You did so good.” he bent down so he could kiss Steve softly. “He’s so, so perfect.”

 

“Thank you Tony, this is everything I ever wanted. Thank you for giving this to me.” Steve sniffled and wrapped his arms around Tony’s neck, pulling him into a hug.”I love you so much.”

 

“Thank you for giving this to me too, sweetheart. I never thought I would have this until I met you.” When they parted he wiped the tears away with his thumbs and kissed him one more time.

 

The nurse returned with their baby and placed him on Steve’s chest so he could scent him. They wheeled Steve into a recovery room and made sure he was settled before leaving the new parents alone with their pup. After a few minutes he handed Peter to Tony.

 

“Hello Peter Pan, welcome to the world.” Tony murmured quietly. He swiped his thumb over the baby’s cheek. “It’s a tough one, but your papa and I promise to protect you and teach you everything you need to know. We love you more than anything, sweet boy.” 

 

Steve was smiling at them, thinking about how lucky he was to have this perfect family. Tony’s face was pure adoration looking down at their son and he was sure his face looked the same as he watched his boys. 

 

The nurse came back in to help Steve nurse him and get the baby to latch correctly, while Tony watched his mate be just as perfect at this as he was everything else. Steve was talking softly to Peter, telling him about all of the pack members he was soon to meet. 

 

“Your Auntie Natasha is a little scary, but she has been so excited to meet you. Clint is annoying and will probably try to teach you to do bad things, don’t listen to him. Bruce is very quiet, but he’ll be excited to meet you too. Thor is loud, but he’s also fun. I can see you two having many adventures down the road.” He continued to speak quietly as they watched Peter nurse until his eyes grew heavy, blinking slowly until he had fallen asleep.

 

Steve looked back to Tony again, with such a happy, proud expression. “We made him.” He whispered. He lifted the pup carefully in order to hand him to his daddy, who cooed at the baby as he took him into his arms. 

 

“We did.” He whispered back, giving the pup eskimo kisses. He pressed one more to his tiny forehead and cuddled him close.

 

Tony settled into a chair with Peter while Steve took a much deserved nap. Tony watched his omega and their puppy sleep, thanking whoever up there let him have this.

This mate, this child, this team. He’d never been more grateful for anything in his life. 

 

Tony eventually put Peter into the bassinet to finish his nap while Tony curled up with Steve on the bed, falling asleep fairly quickly. A few hours later they were awoken by Dr. Tanner. She did one last check up on Steve for the night and let them know Steve and Peter would be free to go the next morning. The two of them decided to wait until they got home before introducing him to the team, wanting to stay in the bubble of just the three of them for a little while longer.

 

The team’s reaction had been hilarious (and sweet).

 

They had waited until they were released from medical so they could have more time to bond with Peter by themselves, which was precious time they would treasure forever.

 

When they were released, they met the team on the communal floor. They exited the elevator, Tony carrying their bags and Steve carrying the baby who was wide awake and taking in all of the new sights and sounds. Natasha was the first to approach, as she walked toward them slowly with the softest expression Steve had ever seen on the redhead. 

 

She studied the boy closely and touched his cheek softly with her finger. “милый мальчик.” She kissed his tiny forehead and stepped back for the rest of the team to see.

 

Clint came forward next, and looked at the baby hard for a moment. “I’ll teach you so many bad things, little dude.” This earned a smack upside the head from Nat and Tony.

 

“You’re not corrupting my child, Barton. Move along you lost your turn,” Tony snapped jokingly.

 

“Awwww…” Clint whined as he sat down on the couch.

 

Bruce was after him. After studying Peter for a few moments he dubbed him precious and moved back again for Thor to come up. 

 

He let Peter grip his huge finger. “Ah yes, he shall be a mighty warrior my friends!” He declared (quietly). “A babe born from two heroes such as yourselves only bodes well for him.”

 

After all of the introductions, Peter began to get fussy so the new parents grabbed their things and headed up to their floor to show their son his new home. 

________________________

 

After a week at home the three of them had settled into a routine. Well, as much of a routine you can have with a brand new baby. On this particular day, Tony had been called into the office to join Pepper in some interviews so Steve was left home with Peter on his own. It felt kind of weird, since Peter was born they had both stayed home to settle in and essentially figure out how to be parents. They weren’t doing too shabby if he did say so himself. 

 

Peter was such a good baby. He rarely cried for anything other than food and sleep, but they knew someday the other shoe would drop. Peter loved cuddles which made Steve the happiest papa in the world. 

 

Tony had finally gotten to watch Steve calm Peter down with his purring and he had taken many pictures. 

 

Peter had been having a hard time sleeping that night, the night after they came home from medical. He nursed each time he woke up which would help get him back to sleep and he was cuddling with his papa which helped their case further. But for some unknown reason he just did not want to sleep. Steve had long since given up on trying to put him in the bassinet and instead had Peter on the bed with him in a bed bassinet.

 

Tony had left the room quickly to get Steve a bottle of water and when he came back Steve was curled up with their sleeping pup purring away. The purrs had soothed Peter just as much as it soothes Tony. He felt like his heart was going to burst. He teared up looking at his perfect mate sleeping with his perfect pup. 

 

Steve opened his eyes, catching Tony staring. He gave Tony a content smile, nuzzling closer to his baby. He reached a hand out toward Tony, inviting him into the bed. The other man climbed in, shuffling until he too was cuddled up with both of them. Tony turned a show on while the two of them watched their pup sleep. Tony made eye contact with the blonde again, voice taking on a joking tone. “So… when can we have the next one?” 

 

Steve laughed, putting his hand on Tony’s cheek. “Let’s at least get this one to a year old, how about that?” 

 

Tony nuzzled his face into Steve’s hand. “That sounds good to me.”

 

They looked at their little baby that they had waited for so long. Tony studied the tiny pup, memorizing his small face. His brown hair was the same color as Tony’s and he had his daddy’s nose and mouth, but he had his papa’s face and eye shape. The two have been arguing over whether or not the boy was going to have blue or brown eyes, Steve was sure he would be a mini Tony with his brown hair and eyes but Tony wanted their son to have his papa’s baby blues. 

 

Steve was a natural at being a parent. Of course they both struggled at times, they were raising a tiny them, but Steve was truly meant for this. Steve’s maternal instincts were impressive. He knew when Peter was hungry or tired or needed either of his parents, he knew when he wanted either Steve or Tony, he was amazing. Tony was learning with him, and from him. 

 

But, as said, this particular day Tony had been with Pepper, leaving Steve alone with Peter. They had been texting all day until a couple of hours ago, which Tony assumed meant they were both getting a much deserved nap. When he arrived back at the penthouse around six, Steve’s phone was on the counter in the kitchen but he and the baby were nowhere in sight. There was water on the counter and floor in front of the kitchen sink which meant Steve had given Peter a bath seemingly recently.

 

He walked through the apartment looking for his boys and eventually found them in Peter’s nursery and the sight before him was something he was going to remember forever.

 

Steve was holding the pup in his arms, dancing slowly around the room. Peter was awake and watching his papa as he sang You Belong to Me to him. When Steve turned and noticed Tony, a soft smile came over his face. 

 

“Hi, alpha.” He greeted the brunette quietly, gliding toward him. Once in Peter’s view his eyes locked on Tony, who reached out to take their son from the other man. 

 

Tony gave him a soft kiss on the mouth and cheek and looked down at the baby. “Hi Peter Rabbit, did you have a good day with papa?” He kissed Peter’s cheek and cuddled him close. “What did you two do today?” He asked as he felt Steve wrap his arms around his waist. 

 

“Mostly cuddled, slept, ate, and waited for you to come home.” Both of them laughed as Steve nuzzled into Tony’s neck. 

 

They were both quiet for a moment, gazing down at Peter as he looked at them as well.

“He’s so perfect.” Tony whispered. “How did we make something so wonderful?” 

 

“I have no idea.” Steve responded, kissing Peter’s tiny forehead. 

 

The two of them watched as Peter blinked his eyes and wiggled his nose before rubbing them. 

 

“Sleepy puppy,” Tony murmured, pressing his nose to Peter’s. “It’s about bedtime isn’t it?” 

 

“Yes it is,” Steve whispered. “He’ll probably nurse until he passes out.” 

 

“Do you want to watch our show?” Tony asked. It was one of his favorite things to do with Steve, he loved cuddling close while they watched and talked about something they enjoyed while spending quality time together. 

 

Steve nodded, smiling. The couple made their way to the bedroom, Tony gathering up Steve’s boppy and pillow before settling their bed bassinet on end of the bed until he fell asleep so they could cuddle. 

 

Steve got situated on the bed, pulling the boppy around his waist and taking off his shirt. Tony handed the baby back to him so he could get Peter comfortable and latched. Tony climbed in and leaned his head on Steve’s shoulder while the blonde put the arm not holding Peter around the smaller man’s. 

 

As the show played on Peter’s eyes grew heavier and heavier until he drifted off to sleep, milk drunk and feeling safe and sound, scenting like a happy pup. 

 

Steve moved to put Peter in the baby bed, but Tony stopped him. “Let’s try putting him in his crib for now. We can put on the baby monitor and we can spend a little ‘us’ time together, and then next time he wakes up we’ll move him back in here.”

 

Steve smiled mischievously, “We can’t have sex yet.” 

 

“No, we can’t have penetrative sex. There’s still lots of other things we can do…” Tony teased, winking at his mate. 

 

Steve nodded excitedly, and they both got up to put Petey in his crib. Steve set him down carefully, smiling when the boy snuffled a little but stayed asleep. He ran the tip of his pinky finger in between his eyes and down the bridge of his nose softly. Tony watched his boys, once again thanking whoever might be up there for this mate and this son. 

 

Tony set up the baby monitor and the two slowly exited the room. As soon as the door was shut and they’d confirmed on the monitor he was indeed asleep Tony basically tackled Steve, kissing him like his life depended on it. 

 

“Do you even know how sexy you are?” He breathed, before attacking his neck with licks and bites. 

 

Steve moaned quietly, pulling Tony back to their room. Tony pushed him back on the bed until he was laying down. The brunette removed his own clothes before pulling Steve’s pants and underwear off. 

 

Tony paused at the end of the bed, taking in his beautiful blushing omega and his beautiful body. Since giving birth Steve had already gone down a few sizes. Bruce theorized the serum had acclimated to the need to grow a healthy baby while he was pregnant, which essentially paused the serum’s effect on metabolism and anything else that could be detrimental to the fetus, so now that the baby was out the serum seemed to be working to regulate his bodily functions again. 

 

Despite the fact that Steve had indeed lost some of the pregnancy weight quickly, it had only been a week since the birth and he was still a good 40 or so pounds over his pre-pregnancy weight. Tony loved Steve’s body any way it was, but he was certainly loving experiencing so many different stages of his mate’s body. 

 

He finally settled over Steve who was whining and gasping, kissing his way up his body starting at his calves. His thighs had always been thick and muscular, and they still are but they’re also still covered over in a layer of pudge. Steve already had a beautiful, plump ass. Since the pregnancy it’s gotten bigger and even more beautiful. So he paid extra attention with his teeth there. He kept moving upward to his belly, softer and more pillowy

now that there was no baby in there. 

 

Steve did indeed get stretch marks across his belly in little pink zig zags. He thought he would be more upset about them but no, he earned them by creating a life, by protecting his son as he grew. He wouldn’t say he loved them, but Tony sure did. He lavished them with his tongue every chance he got, and now was no exception. After his soft stomach, he reached his favorite part. 

 

Steve’s tits were perfect, and Tony was usually an ass man, but Steve made him a boobs man all by himself. They were still big, filled with milk to feed their pup, and Tony rubbed his thumbs over his nipples softly causing Steve to arch his back as milk beaded out, running down his breasts. 

 

Steve let out a high pitched whine, breathing hard. Tony licked a stripe across Steve’s breast, sucking slightly on them. He finally reached Steve’s face, kissing both of his flushed cheeks and his lips before placing his final kisses on Steve’s eyelids. 

 

“I love you,” he whispered, cupping one of Steve’s cheeks with his hand so he could give him an Eskimo kiss with his nose. “You’re the most beautiful thing I’ve ever seen.” 

 

Steve looked at his mate with such love, Tony had to pause his ministrations so he could lie on the bigger man’s chest to hear his heartbeat. 

 

“I love you too, alpha.” He began to purr. He nuzzled his face into Tony’s neck, licking his bond mark. 

 

Steve playfully bit down over Tony’s bonding mark, which effectively kicked Tony into gear. 

 

Three rounds of amazing oral sex later, on both their parts, they heard Peter cry over the monitor. 

 

The two of them smiled at each other, Tony pecking Steve’s lips before rolling off to pull on pants and go grab Peter. 

 

All in all, they seemed to be doing pretty well at this whole ‘parenting’ thing. It didn’t hurt that they made the cutest baby in the world either.
