Steve First.

Honestly, their first clue should’ve been the subtle shift in the pack’s behavior. 

About three weeks after Steve’s heat, he, Tony and the rest of the team were having one of their family movie nights, all gathered around the communal living room. Steve and Tony on one end of the large sectional couch in the center of the room, Natasha and Clint on the other end. Bruce was in his favorite rocking recliner, and Thor was stretched across the loveseat by the window as they watched the first Hunger Games movie. 

They were about halfway through when suddenly: 

“JARVIS pause the movie.” Clint’s abrupt command startled all of them, as he jumped up to his feet. 

“Barton what the fuck?” Tony snapped, glaring. 

“I’m going to get something to drink. Steve, do you want anything?” He asked on his way to the kitchen, turning around to see his response. Everyone looked back and forth between them, puzzled at the random interruption. The only one who didn’t look confused was Thor, who had a small smile on his face. 

Steve looked at Clint with one eyebrow raised. “Uh… water please?” He responded.

Clint finished making his way to the kitchen with a quick, “you got it!” 

Tony looked at Natasha, “what the hell was that?” 

She looked just as confused, shrugging her shoulders. Clint came back with water for Steve and…nothing for him?

Steve accepted it slowly, “what about you?”

Clint settled back on the couch with Natasha, nonchalantly. “Oh I’m good, JARVIS you can start the movie again.” 

Steve and Tony looked at each other before shrugging and watching the movie again. 

The next day, they had just woken up in the morning. They got dressed, brushed their teeth and overall got ready for the day. 

“Babe, are you hungry?” Tony asked, making his way to the kitchen. Before he could open the door though, JARVIS got their attention. 

“Sirs, Miss Romanov has requested your presence in the communal kitchen.” Tony looked at Steve, both of them confused before they got in the elevator to head down. 

As soon as the doors opened they got a whiff of the delicious scent of bacon and sausage. They walked to the island and took in the huge breakfast spread in front of them. There were pancakes, French toast, scrambled eggs, bacon, sausage and a pitcher of orange juice. 

Natasha and Bruce looked to be who had cooked all of this, Clint was sitting at the island and Thor was in chair at the table eating a pop tart. As soon as Steve and Tony walked into the room Natasha asked, “Steve we made breakfast, are you hungry?” Right as she asked, the blonde’s stomach growled. “Perfect, I’ll make you a plate.” 

“Thank you?” The perplexed look on Steve’s face was mirrored on Tony’s. 

“What about me?” The brunette asked with a pout on his face. He reached for a piece of bacon only to have his hand slapped away, eliciting a high pitched yelp from him. 

“Steve first.” She said pointing a spatula at him, with her ‘ don’t fuck with me’ expression. She handed Steve a plate piled high with a little bit of everything, changing her expression into a soft one. 

He reached out slowly for the plate, moving toward one of the chairs at the island with Tony. Confusion still clear on his face, he looked around and saw everyone waiting for him to take a bite. Thor saw back and watched the situation play out with a sly grin on his lips. 

He picked up a piece of bacon and took a bite, and as soon as he did it was like everyone was unpaused. There was talking and the sound of dishes and silverware and soon everyone was in their various chairs around the room. 

After breakfast the team started their own days and Steve and Tony were left alone in the kitchen. 

“So… that was weird, right?” Tony asked, looking at the elevator everyone had just disappeared into. He brought his eyes back to Steve’s where the omega was just finishing his plate. 

“Very weird.” He agreed, and after he put his dishes into the sink Tony took his hand and the two went to their floor to dress and figure out what they were going to do with their day. 

That evening when Steve and Tony returned to the tower, JARVIS informed that the team requested they come to the communal living room. Tony scoffed and rolled his eyes, pressing the button for that floor. 

“Oh don’t be that way Tony, it’s sweet.” Steve nudged the smaller man with his shoulder. 

“Yeah it is, I just don’t get why.” He kept a suspicious look on his face as the elevator opened.

Bruce happened to be walking by and greeted them with a wave and a smile. “Come on in!”

They walked into the living room where there were blankets and pillows piled on the couch, some pretty fairy lights that Steve had hinted he wanted a couple of days ago, and snacks on the coffee table along with some drinks.

“Okay, what is going on?” Tony questioned, looking around at their pack members. “What’s your deal?” He received an elbow to the ribs for his tone.

Everyone else in the room looked at each other with slowly mounting confusion until they all shrugged casually, moving on with what they’d been doing and picking their own spots. Natasha and Clint claimed the opposite end of the couch, but this time Natasha sat in a prime position to be able to rub Steve’s feet once he was under his blankets. 

Bruce directed Steve and Tony to the couch where they’d essentially made a bed with blankets pulled back for them to get in. They settled in and jumped when Clint let out a sudden, “wait!” Running to the kitchen.  

A few minutes later he came back with a large bowl of popcorn. He came straight to Steve with it, handing it over. “Caramel corn!” He yelled, a proud smile on his face. 

That was their next clue. Nobody else in the pack likes caramel corn, only Steve. That meant this truly was centering around Steve and Steve alone. Still, they had no idea what was causing it. 

Steve looked genuinely grateful, excitement lighting up his face. “Thank you!” 

They watched the second hunger games movie, and Steve was so grateful to have this family, this team, this pack. These were truly his people, and despite his trauma from waking up in an entirely different century, he was thankful for everything that brought them together. 

A good ways into the movie, Steve started squirming around, trying to get more comfortable. Tony was asleep on top of him so he couldn’t help him, but suddenly there was a pillow being shoved under his back. He looked over to Bruce who had just picked a pillow up off the floor. “Good?” He asked with one thumb up. Steve nodded and Bruce moved back to his spot. 

When the movie was over the gang got up to go their separate ways for the night. Steve and Tony set out for their floor again. 

In the elevator Tony pushed Steve up against the wall and kissed him like his life depended on it. Steve moaned into Tony’s mouth reaching down to push their throbbing erections together with his hands on Tony’s, truly beautiful, ass while they ascended to the penthouse. Tony pulled back to ask a one word question: “Shower?” To which Steve nodded eagerly. “Okay baby, let’s go.” 

Now, Tony loves to take care of his omega. He would cook for him, clean around the house so he doesn’t have to, do the laundry so he had clean clothes. He spoiled his mate, and he was damn proud of it. 

Steve came from a time where omegas cooked, cleaned, had babies, and took care of the other children. Steve, himself, had always resented that way of thinking. So one of the good things about waking up in this different century was that certain stereotypes had been broken. Omegas ran companies, were not expecting to rear children, could be doctors or any other successful career. Tony adored Steve, and he would never want him to feel that he was expected to do anything. 

Much to Tony’s excitement Steve did have the one “stereotypical” goal. He wanted to have babies. Steve wanted that experience, he wanted to feel his child growing inside of him, he wanted to see the little humans their babies would become. Steve knew there were other options for having children, like adoption or fostering. But no, Steve ached to have a baby, who was a little part of him and Tony. Which, coincidentally, was also one of Tony’s goals. 

So Tony took care of his mate, and loved every minute. He would rather let Steve focus on his art, or reading or literally anything he longed to do. Hell, he’s fucking earned it. 

Reaching the bathroom Steve moved to turn the water on to the perfect temperature while Tony picked their pajamas and gathered their toiletries. Tony got in before Steve, pulling him to stand under the spray. He leaned forward to peck the tip of Steve’s nose before grabbing a loofah and lathering Steve’s beautiful, perfect body up in his black tea chamomile body wash, pausing to wrap his hand teasingly around his mate's dick before moving on quickly. Steve growled, his adorable little omega growl never failed to make Tony want to die from the cuteness. 

He chuckled softly reaching to take him into his hand again, pumping a few times before turning Steve so his whole front was pressed against the glass of the shower wall. He ran his fingers slowly down the blonde’s spine, shocking Steve when he suddenly parted his cheeks and slipped his pointer finger inside his already dripping wet hole. He yelped quietly, not expecting it at all. “Tony!” He scolded. Chuckling Tony added another finger, working them in and out, eventually adding a third. “Oh god, Tony hurry up!” He sounded exasperated, “don’t tease me right now!” 

Tony finally decided to give his omega what she wanted and slipped into him from behind. Steve let out a long moan, reveling in the full feeling he always gets while Tony’s cock is inside him. “Ready baby?” He huffed. 

“You didn’t ask me that five seconds ago when you were shoving your dick in my ass with no warning.” He said dryly. 

“Oh you’re going to be sassy tonight?” Tony laughed. He started moving in and out, gaining a rhythm with his thrusts. He picked up the pace, going harder and harder until the both of them were on the edge of climax. Steve wrapped his hand around his own dick, taking himself the rest of the way. The sound Steve made when he came is what tumbled Tony over the edge as well. After they took a few minutes to catch their breath and cleaned up again,  they fell into bed together and fell asleep cuddled together, Steve purring away.
