Part Three of Tony's Pack You can find the whole series on A03 >>>>>>

Tony was pacing back and forth Bruce was looking over his blood work for gender results. Steve was busy doing an interview about what it was like to be the pack alpha of the Avengers. "Tony sit, are you ready."

"Steve should be here.."

"He told you to find out so you could surprise him. I'll even go shopping with you if you want. So are you ready to find out what your pups gender and second gender is?"

"I'm nervous.. honestly.. Bruce I don't know what to do if they're omega. We deal with insane people very very often, you've seen this." He pointed to his 'heart'. "I couldn't handle it if my puppy got hurt."

"We are your family, we will protect your pup no matter what."

Tony muttered to himself, he sat down and watched Bruce very closely. "Alright just tell me get it over with before I wait till I give birth."

"Your little bundle of joy is in fact omegan," Bruce smiled softly. "He is going to be just like his mother."

Tony grew silent, after a few minutes he finally opened his mouth. "Male omega.. like me?"

"Yes Tony, a male omega just like you." Bruce smirked. "Tony you're okay."

Tears started streaming down his face. "I.. I'm just nervous for my puppy... I'm excited really. Nervous as hell but that isn't anything new for me... just hope that my little puppy is going to be okay."

Bruce hugged Tony. "Really you don't need to worry. You know our pack will never allow anything bad to happen to your puppy." Tony nodded taking a deep breath. Bruce smirked, he hugged Tony for a few more minutes allowing the nervous omega to calm down. "How about we go shopping so you can tell Steve."

"Al..alright.." Tony sniffled before hugging Bruce one more time. Bruce smirked, the two headed out to one of the cars. Happy smiled ready to take them wherever they would like to go. "Happy, will you take us to a puppy supply?"

"Of course sir! I would be more than happy too, shopping for the little one early?"

"Actually planning on telling Steve their gender and second gender. Of course a lot of male omegas choose to transition to females so it may change as they grow, and of course if they just want to regardless they are mine and I will always love them." Bruce smirked as Tony delved into his love for the child that was only a month or two along.

Happy's eyes got big. "You're having a little boy? An omega boy?"

"Shit... you didn't hear that okay... not until Steve does."

"Of course sir. My lips are sealed." Happy hugged his omegan boss. Tony couldn't help but smile, he was getting sappy and he blamed it on his unborn but if he was being honest he was a big softy. He climbed into his seat and smiled as Bruce slid beside him.

"What should I get? Like a blue blanket an-."

"Boys don't always like blue." Bruce smirked. "How about you just find one of those onesies that says cutest little omega and tell him their bloodwork says male."

"That could work." Tony smirked taking a deep breath. He needed to calm down a little if he was being honest with himself. He was on edge and he knew it. He didn't know if he was going to be a good mother, hell he was hardly a good omega now. His upbringing had taught him to disapprove of his omegan ways, he was brought up as mainly beta except when he had to deal with his heats. Which he also wasn't taught to deal with properly. Now he was sitting in his car, with his own private driver, carrying Captain America/Loki's pup.

He was an omega, and he was doing what omegas did.

He just needed to remember that just because he was omega didn't mean he wasn't strong or worth being a member of the Avengers. He then had the realization that someone was going to notice him. He bit his lip unsure of what to do, he didn't want people to see him buy anything. He hadn't gone public about his pregnancy yet, he hadn't left the tower since his scent changed. "Happy," Tony began, "I need you to do something for me. I wasn't thinking..."

"Anything sir." Happy smiled.

"I wasn't thinking, no one knows I'm pregnant yet. Can you just go in, buy a newborn onesie that says cutest omega or Daddy's Little Omega.. something like that."

"Of course sir, when are you going to go public with that?"

"Haven't decided yet.. I need to figure it out.. thank you Happy.. I should have thought about it.."

He was thankful that his windows were blacked out. A few people knew who Happy was just from photos and news articles but he needed to get something for Steve. He didn't want to just tell Steve, he wanted it to be special. He already had a dinner ready for tonight on the rooftop of the tower. He needed to make it special. He would tell Loki when he could but Steve was his mate. He needed his mate to know before anyone else. He already made the mistake of telling Happy, so no one else could know.

Happy was quick, he got one of the onesies he was asked to get. He got in and got out without anyone raising an eyebrow. He smiled as he gave it to Tony. "Thank you Happy."

Tony looked over the onesie, it was a pale green with tan writing. Daddy's little Omega was sprawled across it. Tony couldn't help but smile at it, he shuttered at the material however and vowed his pup would not be wearing it ever. He would be buying from high end puppy supply stores. His pup would be treated the best, given anything they want.

Arriving back at the tower Tony made his way up to the rooftop, his dinner was practically finished being set up now. He sat down at the table the little onesie hidden away. As Steve entered the tower Jarvis began to speak. "Sir requests you at the top floor of the tower."

"Thank you Jarvis."

Steve made his way up the stairs and smiled seeing Tony waiting patiently. "How was the interview alpha?" Tony asked as he stood up with a smile, he hugged his alpha tight. Steve smiled kissing the top of his forehead.

"It was good 'mega," Steve smiled, "so, this special dinner means you have something to tell me."

"I do, I found out our puppies gender and second gender. Now which do you want to know first?" Tony asked curiously. If Steve had a tail it would be wagging.

"Oh 'mega I want to know both." He remarked trying not to act too eager. Tony snickered. "Come on just tell me."

"Alright alright, here." He pulled out the onesie and handed it to him. Steve looked it over.

Daddy's Little Omega.

"We are having an omega?" Steve asked his smile big. "I promise to protect them, promise it 'mega. I will lay down my life for our pup just as I would for you."

Tony blushed. "Oh Steve... you really know how to make me smile.." He blushed hard. "Our puppy is omegan, but they are a biologically male."

"We are having a son." Steve was over the moon.

Tony nodded happily. "But we will support them if they decided being female, or even gender neutral or if they want to use they/them pronouns is who they really are. Being a male omega is a weird experience. I know I am male, but I'm not like other males. Our puppy won't be either."

"They will be our child Tony, no mater who they are. They are ours, our puppy no matter what. I will do anything I need to do for our child. Our little Avenger."

Tony couldn't help but feel gratitude for his mate in that very moment. Tony had been worried about Steve's traditional upbringing, but Steve was nothing but welcoming and accepting. Tony leaned over the table and kissed him deeply. "Thank you Steve Rogers for being my mate."

"Your mate and our puppies father. Always Tony."

Tony blushed before kissing Steve once more.

He knew his puppy was going to have a wonderful life, get to be whoever they wanted to be. They would always be loved by their parents and have the best life Tony and Steve could give them.
