***** All I Want *****
Chapter Summary
     A short preamble.
Tony hoped that everything would be fine, that nothing would happen and Peter
would never make any comment. Honestly, he was terrified of the teen's
reaction. What if Peter wasn't ready for kids? What if the thought of
procreating with Tony completely disgusted him? Was Tony ready for kids? Was it
wrong of him to wait until Peter started getting morning sickness to reveal he
thought the omega was pregnant? Yes, it was wrong, because they're supposed to
have healthy communication in their relationship, but this just wasn't
something that Tony could address. He had never had to address this type of
situation before. Because Tony loved Peter more than he had ever loved anyone
before, and he couldn't mess this up. 
But as Peter was puking his guts into the toilet before the sun had even come
up, Tony just knew. He could feel it in his bones, like there had been an
offset to the universe. When he took Peter to the infirmary and had them do a
blood test, the kid was too exhausted to even ask what the blood test was for.
When the lab tech silently handed him the results and left the room without
another word, Tony could feel bile rising in his own throat. He wondered if he
was going to have another anxiety attack. He honestly hadn't had one of those
in awhile since Peter had entered his life for good.
"Peter, honey, I know you're tired and not feeling the greatest, but we're
going to have to have a pretty serious talk starting about now," Tony started,
sitting down on the exam table next to him. 
"Tony, I know I'm pregnant, I don't need an alpha to tell me that," Peter
sassed, eyes drooping as he leaned against his mate. 
"Y-you... You know?" Tony glanced down at him, stunned. 
"We had unprotected sex and the next morning when I woke up my inner omega was
way too happy. Suddenly my instincts are telling me to avoid caffeine and fish,
and my IQ isn't zero, babe. I'm well aware that I'm pregnant, and that you've
known for awhile that I'm pregnant, and that you've been drinking more when you
think I don't notice but I actually do," Peter replied sleepily, eyes closed
the entire time. 
"You're not... mad?" Tony picked him up, carrying him back to their room so
that he could rest properly. 
"Oh, babe, I'm furious. You're going to wait on me hand and foot for the next
few months and your wallet is going to cry when I'm done with it."
"You want to keep the baby?" 
"Tony, if I've known for this long that I'm pregnant, then yes, I want to keep
the baby. But you're going to tell Aunt May."
"Then rest in peace to my reproductive organs," Tony sighed as he tucked his
omega into bed, running a hand through his hair.

Chapter Notes
     Sorry it took me so long to get this chapter out I'm a college
     student taking max credits this semester because I apparently hate
     myself and want to die
"You can't back out from telling her. She has to know. Also, I want a baby
shower. You should probably get to planning that, because a watermelon is going
to be shoved out my ass soon enough. You do love me, right, Tony?"
The shit-eating grin on the teen's face was not helping the situation at all.
Once the nausea had worn off, Peter lounged on the couch, loudly munching on an
apple. Tony had stuck to pacing around the large room, anxiously running his
hands through his hair. 
"Why are you so calm?" he asked finally, and Peter shrugged in response.
"This was going to happen eventually."
"What was going to happen eventually?" Pepper asked as she walked uninvited
into the penthouse.
"Who the hell let you in?" Peter asked, sitting up from his position on the
couch.
"Language, Peter," she chastised. 
"Fuck you, bitch." Peter took another loud bite out of his apple. 
"Tony, I really think you're a terrible influence on him," she said pointedly,
typing away at something on her tablet.
"Do not blame that on me, that is all him." Tony raised his hands defensively.
"I'm two months pregnant," Peter said, tossing the apple core at Pepper. She
had looked up from what she was doing and froze, the core hitting her smack in
the head, but she didn't even flinch. 
"Way to go, Peter, you broke her," Tony whined, plopping down next to him on
the couch. The omega curled up next to him, starting to purr, and the noise
snapped Pepper out of whatever daze it had put her in.
"Is he keeping it?" She directed the question at Tony, which Peter took offense
to. Just because he was omega didn't mean that he didn't get to make decisions
about his own body.
"Um, yes, I am keeping them, thanks for asking," he snapped.
"When do we want to tell the press?" 
"Who said anything about telling the press?" Tony raised an eyebrow, wrapping
an arm around Peter protectively. 
"Well, you can't keep him hidden up here forever, people will eventually get
wind of this. It's better to be straight-forward about it, so that none of your
staff sell the story. Because if someone sells it, it'll be a scandal instead
of an announcement, which will reflect more negatively on Peter."
And for once, it almost seemed like Pepper was looking out for Peter. But he
wasn't an idiot, he knew better. This would reflect back on Tony, and if that
happened, it would reflect negatively on Stark Industries, which seemed to be
the only thing that Pepper really cared about. But, the bitch did have a good
point.
"We'll go public once Tony tells Aunt May, isn't that right, babe?" Peter said
smugly, enjoying the grimace on both adults' faces. 
 "Right," Tony replied, looking like he was going to be sick.
-
Driving up to the small Queens apartment, Peter hid on the inside how nervous
he actually was. He knew that May would love him no matter what, but she
already disproved of Tony being his mate, even if it was something that
happened to save his life. She had barely reached out to Peter once he had
moved in with the billionaire, it was always Peter that had to make the first
move. They had gone out together a few times for lunch and dinner, but May was
always overwhelmed from all the paparazzi. He knew that the older woman felt
like she had been replaced from Peter's life, and that he didn't need her nor
want her, but sometimes he felt really lonely without the mother figure in his
life. He had become increasingly close to Tony, and he still had Ned that he
could text at any hour of the day, but he felt like there was a gaping hole in
his relationship with his aunt now. His aunt, who at one point was the only
person in the world that he would willingly give up everything for. 
He wiped his sweaty palms on his jeans, Tony's arm thrown over his shoulders a
comforting weight. They climbed the stairs together, Happy trailing behind them
by a few feet. They had called May beforehand to let her know that they were
planning on coming over, so it was no surprise when they knocked on her door.
She swung it open quickly, and threw her arms Peter into a bear hug. Peter
deeply breathed in her comforting scent, which helped ease his nerves. She
welcomed them in, and Happy politely remained outside the door, letting the
family have some privacy while discussing the matter.
She directed them to the living room, offering them coffee, which Tony accepted
and Peter quickly declined.
"You sure, Peter?" she asked, knowing the boy usually never turned down the
offer for coffee.
"Actually, um, that's why we came here to talk to you," he started, deciding it
was best to just jump right in, "but you probably want to sit down for this."
"Are you dying?" she asked as she sat, eyes getting wide.
"Not quite," Tony chuckled nervously, squirming a bit where he was seated.
"Peter's pregnant," the older man stated in a matter-of-fact tone, and May
squinted her eyes at him in confusion.
"He's... pregnant?" she restated, pointing a finger at her nephew, as if they
were talking about a different Peter.
"Yes..." Tony answered, but he sounded unsure of himself, as he said it slowly,
drawing the word out.
"For how long?" 
"Two months, but it was only confirmed with a blood test this morning," Tony
quickly explained, knowing May would kill him if they went two months without
telling her something as vital as this. 
"How are you feeling, Peter?" she asked, not sounding mad in the slightest.
"Good, kinda nervous, to be honest," he replied, knowing that his aunt would
know if he was lying to her. 
"Well, know that I'll be here for you throughout this whole thing. Now, why
don't you go into the kitchen, help yourself to some food? You must be
starving," she said sweetly.
"Actually, I ate before I came here-" but Peter was cut off. 
"Peter, go into the kitchen so that I can have a talk with Tony," she said, but
Peter knew it was an order. Sending an apologetic look to his alpha, he stood
quickly, shuffling into the kitchen.
The teen didn't need his advanced hearing to hear May and Tony both stand, with
her crossing the small room to smack Tony across the face. He flinched a bit,
feeling sorry for his mate, but nevertheless helped himself to some cookies
that he found while May lectured Tony about being responsible and using
protection during sex.
Yikes.
After a good ten or so minutes, they both walked into the kitchen, Tony
discreetly nursing a cheek that would probably bruise soon enough. May went and
brought Peter into another big hug, pressing a kiss to his hair. 
"I'm excited for you," she said, and Peter knew that everything would be
alright.

Chapter Notes
See the end of the chapter for notes
Things were going surprisingly well. Right now, Peter's biggest concern was how
his mutated genes were going to affect the baby, but the doctors reassured
Peter that the worse case scenario was that he would pass his powers along to
the baby. Which, in Tony's opinion, was a bad thing, because it newborn babies
were difficult enough, one with superpowers wouldn't be much easier. 
Speaking of things that weren't easy, he hadn't told his friends yet. He had
invited them over, with Tony's approval, and they would be here any minute.
Peter had chosen to wear one of Tony's old sweatshirts that was significantly
baggy on him, because he wasn't even showing, but his nerves were telling him
that they'd be able to tell instantaneously otherwise if he didn't make an
effort to hide any possible physical evidence of what he'd done. 
Both MJ and Ned were ecstatic to be hanging out with him again, all three on
the couch and eating pizza, catching up like old times. Ned filled Peter in on
all the latest happenings around school, on how people still talked about Peter
since he had become a local celebrity since mating Tony Stark. Ned complained
about all the people that would pester him so that they could meet his famous
friend, but under the surface, Peter knew that Ned enjoyed the attention. And
that wasn't a bad thing, Peter was happy for him.
MJ was just as reserved as ever, offering a snarky comment here and there, and
filling in a few details when Ned blanked during stories. It was nice, having
her calming presence, especially since Ned had a more energetic personality. 
They put in a movie, snacking on even more junk food, and when it finally
ended, it seemed that the two friends were gathering their things, ready to
leave. It was a Sunday, they definitely had to leave soon because they had
school tomorrow, but Peter couldn't find the words. It was like they were
caught in his throat, and he didn't know how to tell them the most important
news of his entire life. Well, being Spider-Man might be the most important
news, but this seemed colossally harder to tell, and it might've been because
it was something that could change their opinion of him.
It was one thing that he was an Avenger, it was another if he was just another
knocked-up omega. Would they judge him, ridicule him? Decide to stop being his
friend?
"Dude, you reek of distressed omega, what's going on?" Ned asked calmly, and
Peter realized he had fallen down a rabbit hole in his own mind. 
"I-I..." he stammered, wrapping his arms around himself, burying his nose in
the sweatshirt and breathing in the smell of his alpha. He was fine, he could
do this.
He was Spider-Man, he could do anything he put his mind to.
"I'm pregnant," he stated quietly, but loud enough that both of them could hear
him so he wouldn't have to repeat himself.
"Congrats," Michelle said, coming up and giving him a quick hug. When she
pulled away, Ned came and squeezed him a lot tighter. 
"You guys aren't freaking out?" Peter asked, raising an eyebrow.
"Why would we? You're recently mated, this was something we saw from a mile
away. Had you not been mated, we would most definitely had freaked out," Ned
laughed lightly, and Peter felt relief wash over him like a wave. 
"How far along are you? How does Mr. Stark feel about it?" Ned dove into twenty
questions, and Peter answered them as best as he could. After another hour,
they all finally said their goodbyes, and Peter felt emotionally drained.
Plopping down on the couch, his eyes slipped closed.
-
"Who's the kid?" A new voice startled Peter awake, and he registered that it
was morning, early light pouring in through the windows. When he opened his
eyes, he realized the voices were coming from the kitchen, and it prompted
Peter to slowly stand up and walk towards the source of the noise. 
"Peter Parker. Surprised you don't recognize him from the news," Tony's voice
was a reassuring presence that everything was fine, that strangers hadn't
somehow gotten past the crazy good security system and broken into the
apartment. 
"Whenever I see your name in the news I usually tune it out. It's mostly gossip
anyways, right?" The voice sounded eerily familiar, and Peter couldn't remember
where he had heard it before.
"Well, as of recently, it's been pretty accurate. I'm mated now," Tony said.
Peter peeked around the corner, seeing a tall blond man facing away from the
doorway, while Tony prepared something at the counter. 
"Yeah, I can smell that. This whole place is dominated by the smell of omega.
Who is she?" the strange man asked, and Peter cleared his throat, announcing
his presence. The stranger turned to face him, and Peter jumped a bit where he
was standing.
"Captain America? You're not- Tony?" the young teen took a step back, confused.
What was a war criminal doing in his kitchen?
"It's fine, Peter. Cap's here to help, not harm. We're all on the same side
right now," his alpha explained.
"You promise you're not going to try and kill me again, right?" Peter asked,
and Steve tilted his head in confusion.
"Have we met before?" the solder questioned.
"Yeah, at the airport. Captain America, meet Spider-Man." At Tony's words,
recognition flooded Steve's eyes.
"Kid? The one from Queens?" 
"The one and only," Peter replied, smiling nervously.
"What's he doing here?" Steve asked Tony, but there was no malice to his tone.
"You asked about an omega..." Tony answered, raising his hands and backing up a
few feet while the information processed in the soldier's brain.
"What the hell, Tony!?" Whoop, there it is. Steve rushed to the other side of
the island, grabbing the front of Tony's shirt.
"He's just a kid!" Steve yelled, and Peter felt dizzy. With the two alphas
butting heads and releasing hormones like crazy, it was hard for him to stand
upright, especially since he was ultra-sensitive.
"Steve, I can explain-" Tony started, but was cut off by more yelling.
"How can you explain this? I leave for a few months and come back to this? Do
the others know?" 
"Not all of them, no. I was planning on telling them all at once." Tony was
remaining surprisingly calm, and Peter was grateful for that. If his own alpha
had started getting angry, he'd probably do something embarrassing in front of
Captain America (of all people) like submit. 
"Tony's my true mate," Peter spoke, leaning against the door frame for support.
With those words, Steve dropped Tony's shirt, taking a step back.
"Shit."
"You can say that again. And before you start apologizing for your actions and
whatever, you should know he's pregnant too," Tony chuckled nervously, and
Steve saw red again.
After another ten minutes of yelling, all three were scattered around the
living room, Peter eating a sandwich while the other two stared on in silence.
It was probably some weird alpha posturing thing, but Peter could care less.
Food had never tasted better.
