Malibu Hospital – Malibu, California

Tony Stark was not known by his deep love for people or things. He kind of didn't love anything but him until a few years ago, where life decided she had it with him and taught him a lesson. Tony realized he loved Pepper – a key point in his irrefutable change. He also learned to love the world he lived in, by building Iron Man. Tony also loved being part of the Avengers. But nothing, nothing, will ever come close to be loved like his flesh and blood would be. Tony wasn't even aware that you could love something so much, so painfully much, in just one second. His eyes watered and a few tears slipped, but he wasn't less of a man for it. After all, his children had just been born and they stole his heart right then and there – just by screaming to the world how displeased they were by being so rudely taken from their Momma's womb.

"Tony," Pepper whispered tugging on his hand.

He turned his eyes to his tired wife. "You did an amazing job, Pep, I'm so proud of you," Tony said while trying to keep his voice from trembling. "I love you," he breathed kissing her forehead.

"I love you too," she smiled a tired smile.

"Daddy, your little girl is ready," the nurse whispered bringing the pink bundle over to Tony.

Tony looked to Pepper and she only nodded. Looking back to the nurse he felt a bit awkward. How did you hold a baby again? "I might break her," he said. "I really don't know how to hold her and…" Pepper and the nurses chuckled.

"Don't worry, Mr. Stark," the nurse – Jenna – smiled warmly at him. "It comes naturally, I guarantee you that."

Jenna transferred the baby girl to her father's arms and helped Tony find a good position. "There you go," she whispered.

A bit shaken he relaxed his arms, eyes glued to the beautiful baby girl squirming in his lap, whimpering with her eyes closed. "It's alright, it's alright," he soothed her and she stopped squirming. "There you go, you're safe and I know, real world sucks, but I will make it better for you," Tony said in a hushed tone.

The baby whimpered again, only to open her eyes, staring right into Tony's liquid brown ones. He let out a little gasp. They were the clearest grey-blue he had ever seen. "She's beautiful," he said, turning to look at his wife who was quietly crying. "She looks like you," he grinned. "Hi, Sarah, I'm the coolest Daddy you could've asked for," he smiled at the baby girl, gently rocking her in his arms.

"The boy is ready," the other nurse, Helen, brought the second baby, who turned out to be a boy, over to his Mom who eagerly took him in her arms.

"Hi, handsome," she breathed looking at the quiet baby who just gazed at her with eyes resembling his sister's. "Oh, Tony, look at him. Look at both of them! Can you believe this?" Pepper shook her head, tears streaming freely from her eyes. "I'm so happy," she choked on a sob.

"That's why you're bailing your eyes out?" he teased looking lovingly at both of his children.

"I'm happy and my hormones are still running wild," she mumbled through tears.

"I know, sweetheart, just teasing," Tony smiled and carefully sat down next to Pepper in her bed.

"He has your nose," Pepper pointed out.

"She has your lips," he said.

"They're ours," she breathed. "You and I did them."

"And like everything else we do, they're flawless," he grinned looking at his boy. "They're finally here," Tony breathed.

"Sebastian and Sarah," Pepper smiled, proud of the names in which they finally settled – two days ago, out of a list of a hundred.

"We're doing this, we really are parents," he chuckled.

"Mr. and Mrs. Stark, we will need to take little Sarah and Sebastian to run the routine tests and Mrs. Stark, you need to clean up and be transferred to your room, you'll have them back in no time," Jenna said, approaching the couple pushing in front of her, two plastic cribs.

"So soon?" Tony frowned.

"I know, you don't want to let them go," Jenna smiled. "But, Mr. Stark, you can go down to the nursery and watch them while my coworker takes care of your wife," she offered. "Besides…your friends…" she seemed a little amused. "Are in the waiting room," she finished.

"You should go a let them know everything's ok," Pepper said while nodding at the nurse to take Sebastian. She kissed his forehead, before handing him to Jenna, who gently cuddled him before putting him down on the crib.

The process was repeated with Sarah and the Stark couple watched as the nurse wheeled the cribs out of the delivery room. Tony turned to face Pepper and then kissed her softly on the lips. "Thank you," he whispered matting their foreheads.

"For what, darling?" she asked cupping his cheek.

"Bearing with me, loving me, giving me two beautiful children," Tony enumerated. "I never deserved you and you could do so much better, yet you stayed with me."

"I will always be by your side, Tony," Pepper whispered. "Sure, you can be a handful sometimes, but that's the man I fell in love with. I fell in love with the man who sometimes acts like a child, but has a heart of gold and when he wants he can be the most extraordinary human being, risking his own life to save others."

"I love you," he smiled and kissed her again.

"I love you too, Tony," Pepper said.

"Mr. Stark, I suggest you make your way to your friends while we take care of your wife," Helen said with a warm smile. "She'll be in her room in a little while."

"Go, Tony," Pepper said.

With a nod and a last passionate kiss, Tony left the delivery room, walking down the aisle with a kind of spring to his steps. He approached the waiting room and his eyes widened a bit. Everyone was there. Well, except Clint and Natasha but those two were also getting ready for their baby and Natasha was not authorized to fly at eight months pregnant. But…Steve, Bruce, Thor, Jane, Maria, Phil, Rhodey and Happy were there. The group all stared at Tony, expecting news.

"Well?" Rhodey broke the silence.

"I'm a Dad," Tony grinned. "A boy and a girl," he said and suddenly saw himself engulfed in a sea of hugs, pats in the back and chorus of 'congratulations'.

"What are their names, Tony?" Jane asked leaning against Thor who kissed her hair.

"Sebastian and Sarah," Tony said proudly. "They will be the most spoiled kids in this earth," he beamed.

"I don't doubt it," Steve chuckled.

"How's Pepper?" Phil asked.

"The nurse is taking care of her and she will be in her private room in a little while," Tony said. "You can visit her then, if she's not asleep."

"How about the babies, where are they?" Maria inquired.

"Routine tests, they'll be at the nursery," Tony smiled.

"Aw, man, you're so lucky," Rhodey said with a big grin, laying an arm around Tony's shoulders.

"Guys, maybe we should let the little family have their moment," Bruce started. "It's close to two am and we should probably swing by in the morning," he smiled and everyone nodded in agreement.

"Big guy's right," Thor said. "Congratulations, Tony, on your heir and heiress," he beamed. "I'll bring gifts tomorrow."

One by one, everyone left, except Happy and Rhodey. "Do you need me, Boss?" Happy asked.

"Yes, Happy, go by the house and bring the baby bags that we- I forgot," Tony scratched the back of his head. "Also, bring Pepper's bag too," he cringed remembering that Pepper reminded him of the bags but Tony completely forgot. "If you could install the baby seats in the car…"

"Of course, Boss, I'll get right to it," Happy said. "Congratulations," he grinned before he left.

"C'mon, let's see my godchildren," Rhodey grinned as he and Tony started to walk down to the nursery.

"Who asked you to be the godfather?" Tony scoffed.

"Oh please, I've been sticking with your sorry ass for the past decade, I get at least to be the godfather to one of your kids," Rhodey huffed playfully.

"I'm messing with you," Tony smirked. "Pepper and I talked about this. You and Maria are the godparents to Sebastian. Bruce and Natasha are the godparents for Sarah. It's perfect."

"Man, I'm spoiling those kids so much," Rhodey sighed and the two of them walked in front of the glass that showed the nursery. "Where are they?" he asked quietly.

Tony grinned spotting his children immediately. "Down there with the nurses, getting checked up," he said, pointing.

"Aw, they are adorable," Rhodey gushed.

"Don't you think you and your wife should take the next big step?" Tony teased. "I'm not sharing my children," he warned.

Rhodey shrugged. "We're trying," he said. "Oh, look at those little things! Thank God, they have Pepper's good looks," he said in a teasing way and Tony punched him in the shoulder playfully. "You're very lucky," Rhodey said in a serious tone.

"I know. I just hope I'm better at this than my Dad was," Tony shook his head. "I can assure you those kids will know how much I love them every day, I can't make the same mistakes that he did and I will not let them grow up to be self-centered billionaire kids that have everything they want, when they want."

"So you're admitting you are-"

"Shut it, Rhodey," Tony rolled his eyes.

"Don't worry man, you'll do great," Rhodey smiled patting his friend in the back.

"I know. I have Pepper," Tony said.

Next morning, Pepper woke up a little confused. She didn't even recall falling asleep. Last thing she remembered was getting a shower and changing into those awful nightgowns from the hospital (she knew Tony would forget her bag!). Pepper shifted, feeling a little sore, but she guessed that was normal, seeing that she just had two babies popping out of her uterus. Adjusting her eyes to the light coming from the binds, she turned her head and a bright smiled graced her face as she saw her husband hovering over the oversized plastic crib with the twins on it. She then realized that there were flowers all over the room. Bright red, pink and white roses! White, blue and pink balloons. A few unopened gifts.

"Morning, I suppose," Pepper said, startling Tony who turned to his wife with a bright grin.

"It's eleven," he said and giving one last glance at the two sleeping children, he went over to her side. "Morning, love," he said kissing her forehead.

"How are they?" she asked.

"Healthy and right now, sleeping," Tony replied. "I love to watch them sleep. I might sound like a creep, but I like to watch their little chests rise and fall."

Pepper chuckled. "I think it's normal," she said.

"You should brace yourself, everyone was already here leaving gifts and gushing over the twins, but they'll be back in full force," Tony warned.

"Oh, have you talked to our persons of interest for the godmother and godfather's role?"

"Yes, and they couldn't be more excited or giddy," Tony chuckled. "I think Maria just dragged Rhodey out so they could buy a big plush toy. As far as I know, Natasha and Bruce already have an oversized toy ordered."

Pepper laughed. "We have some really good friends. Our children are very lucky to be surrounded by all this love," she smiled. "I can't wait for them to be awake. I want to hold them," she pouted.

Tony smiled. "I now that. They fell asleep like an hour ago, so I guess they'll be awake soon. You need to rest. Remember what the books said, when the baby sleeps the Mother sleeps. Helps you get your rest and God knows we are not having that when we take them home," Tony pointed out.

"I'm terrified and excited," Pepper said.

"You and me both, darling," Tony mumbled. "Let's enjoy the moment, and worry later," he said kissing her forehead.

Two weeks later

Natasha and Clint's House – New York

Natasha huffed, she was so round she couldn't see her feet and now she walked awkwardly. She blamed Clint. He was to blame. He knew that, which made him tip-toe his way around her lately. Clearly, Natasha was scarier when pregnant – blame it on the hormones.

That morning, Clint had an emergency meeting with Fury and Natasha was left alone on their house. She needed something from the top shelf of the closet, from Clint's side and she growled when she couldn't reach it. Stretching as much as she could, she pulled the scarf that was underneath the box and things tumbled down to the floor. Much more satisfied she resorted to bending down and picking up only the book she wanted when something caught her eye. She froze. Her body went rigid. That couldn't be what she thought it was. It was…not, it wasn't possible, and it couldn't be. Letting out a shaky breath, she bent down again and picked up the small velvet box.

Her bottom lip trembled – has she mentioned how much she wanted to kill her own hormones for making her this sappy? – as she opened it and was faced with a beautiful engagement ring. It was a solitaire, with a big round diamond. Elegant and simple, the opposite of their relationship, but still them! Closing the box she wondered for how long he had it, when did he decided that marriage was an option? She never mentioned it. Hell, she wasn't planning a baby, let alone getting married.

Suddenly, a sharp pain on her lower abdomen made her gasp and drop the box. Natasha held her stomach as she breathed. "Easy there with the kicks, honey," she muttered rubbing her stomach with a soft smile, her baby – gender unknown, the little one was shy – was a strong kicker. Another sharp pain made Natasha bend over and she felt liquid between her legs. Her eyes widened. The baby wasn't kicking! These were contractions. It was the real thing.

Taking a deep breath, she waited for the next contraction, counting the time.

Twenty minutes apart.

Now, calling the responsible for her misery…

"Hi, Natasha," Coulson answered.

"Where is he?" she hissed. Why in the world was Coulson answering Clint's phone? She wanted to yell at her partner, not at her handler.

"Meeting with Fury," her handler replied with ease.

"Call him," she growled.

"It's everything alright, Tasha?" Coulson asked noticing her weird tone.

Before she could reply, another contraction hit and she whimpered in pain. "No," she let out.

"Oh, God, is it the baby?"

"My waters broke!"

"I'll get him, I'll get him," Coulson quickly said and she could hear him running.

Carefully, Natasha left the bedroom and climbed down the stairs to the kitchen, supporting herself on the counter.

"Clint!" she heard Coulson yell.

"Oh, there's my phone," Clint said.

"It's Natasha," Coulson said.

"What's wrong?" her partner asked when he snatched the phone from their handler.

"Your baby…is trying to rip me apart…" she growled into the phone and then gasped in pain. "Just…get over here…"

He didn't reply. "Clint?"

Natasha heard a few laughs before Coulson picked up the phone again. "Yeah, we'll get him to the Hospital as soon as he wakes up," Natasha stopped dead in her tracks. Was that a different way to say that her partner fainted? "Maria was closer to your location and is already on the move!"

"I don't care if you have to tase him, Coulson, I want him there before I arrive, got it? Or else…"

"Yes, Natasha, he'll be there, no need to get violent," Coulson said and hung up.

The spy groaned when another contraction hit and the pain was almost unbearable. Not even ten minutes later after the call ended, Maria was knocking at the front door and yelling for her. Natasha rolled her eyes and went to open the door. "I'm having a baby, not getting deaf," she said.

"Do you need anything before we go?" Maria grinned.

"My bag is in my room and the baby bag is in the nursery," Natasha sighed and while Maria went upstairs to get the bags Natasha slowly made her way to the SHIELD car.

Maria caught up with her and helped her into the front seat, putting the two bags in the back seat.

"How's the pain?" Maria asked getting into the driver's seat.

"Just drive," Natasha said, biting her lower lip to keep herself from saying something less pleasant.

Shaking her head, the brunette started the engine and breaking almost every speed law, they arrived to the hospital. The contractions were now five minutes apart.

Natasha wasn't a woman of many emotions, but when she saw Clint at the Urgencies, waiting for her, she felt like crying because she wasn't alone anymore.

"Easy," Clint whispered helping her out of the car.

"You fainted?" she all but yelled.

He cringed. "Maybe," he muttered, holding her hand. "How are you feeling?"

"How am I-" she was interrupted by another contraction that had her holding on to his hand by dear life.

Clint did everything in his power not to wince at her grip. He was sure that by the end of the day he wouldn't be able to hold his bow. "Let's get you inside," he said.

Natasha only nodded.

Natasha had been through some very bad torture. Really, really, bad! Electrical shocks, beatings, she had been shot during missions, she had cracked several ribs once and let's not forget she fought aliens awhile back…but nothing, and she means nothing, was worse than giving birth. "Natural and beautiful thing, my ass, this is awful," she cried – literally. She was holding Clint's hand with tears running down her face. "Make it stop!"

"It's almost over," Clint tried to soothe her, even if he had no clue how much longer it will take; they've been in the delivery room for a while now.

"You don't know that, shut up," she yelled. "It's your fault. Your damn fault! You were the one who forgot protection."

Clint nodded robotically. Yep, everything was his fault, blah, blah, blah. He just didn't tell her otherwise because he wanted to live to see his child.

"Oh my God! I hate you, I hate you," Natasha was going on and on, and Clint was pretty sure he already had zoned out, thinking about how he was going to suck in the parenting job, even though Natasha always told him that from both of them, he would do the best.

He was startled when Natasha gave an especially loud yell and followed by that there was a high pitched wail. Natasha fell back into the bed, her breathing rage. His eyes widened at the little pink thing squirming in the doctor's arms, and complaining, filling the room with cries.

"Congratulations, you have a daughter," the Doctor said with a happy smile, while the nurse took the baby to be cleaned.

"She's beautiful," he muttered. "Natasha…she's…beautiful," Clint whispered looking over to his partner.

Natasha looked up to him with a happy, but tired, smile. "Of course she is! Did you expect anything less from us?" she giggled.

Clint turned his head, trying to get another glimpse at his baby girl.

"Clint?"

"Yeah?" he replied still watching as the nurses weighted the baby – who by the way, wasn't happy and was whimpering.

"Yes," Natasha said.

"Yes, what?" he asked distracted.

"I'll marry you," she said amused by his distraction. "I found the ring."

"Oh, ok, the-what?" his head whipped so fast towards hers, she feared he got whiplash. "You…you…you what? Natasha, that was on the top shelf of the closet, far from your pregnant lady reach! I told you to keep from high places and you…you…you…" Clint's baby blues softened as he blinked taking in all of her words. "You'll marry me? I thought you were going to throw the box at my head and tell me to get a grip!"

"That thought did occurred to me but…" she started but the nurse interrupted her.

"Here's your baby girl, Momma," the nurse cooed, bringing the pink bundle over to Natasha's arms.

Like a reflex, Natasha held her arms in the correct position and when the baby was settled into her arms and opened her soft blue eyes, tears pooled at Natasha's eyes. Clint wasn't far from crying – this was a good reason for it, hell, he even heard that Stark was babbling in tears over his twins – as he sat down next to his family, wrapping an arm around Natasha's shoulders, running a finger over the baby's cheek.

"But look at her," Natasha went back to her point. "She deserves everything. We need to provide her what we didn't have. I don't want her to grow up to be an assassin or a loner. I want her to have every freaking cliché in this world," she sniffled. "I know our life isn't normal, our jobs are not easy, but I'll be damned if I won't try my hardest to make her the happiest girl in the world."

Clint kissed her temple. "I'm right by your side, always," he whispered.

"Welcome to the world, Alexandra," Natasha smiled at the baby girl who gurgled.

There you have it. A bit delayed. But yesterday was exam day, and I had a lot to study.

Now, "A Stark Pregnancy" is over, but, I'm thinking about a sequel, since you guys loved this one so much. Next, I would like to do some parts of their childhood – birthdays, play dates, cute and funny stuff…and I would like to know if you would approve of that. Also, if you do, leave a prompt related to their childhood and I'll reorganize them by chronological order. The title will probably be "A Very Superhero Childhood" or even "Growing up with the Avengers", or something along these lines.

I love feedback, so please review.

PS: To any of you who's curious, SHIELD's main base is in New York, that's why Maria, Coulson, Clintasha and Steve all have houses there. Thor is not from this world, but when he comes, he stays at the Stark Tower in NY, where Jane works as a scientist. The only Avenger that lives close to Pepperony is Bruce, who works at Stark Industries lab.

PPS: I never read the comics, don't judge :s I do, however, do a lot of research.
