11 weeks into the pregnancy
Tony didn't think he'd ever seen someone so comfortable while being pregnant, but of course Steve surpassed expectations. During Tony’s research, he’d read through a lot of mom blogs (so he wanted to be prepared, sue him), and about 80%of them complained about at least five things caused by the pregnancy. Morning sickness, cravings, weight gain, hormones, food aversions were the most popular, but there were plenty more. Tony had prepared himself to deal with the worst of it and so far… there weren’t any of the things he’d read to expect.
Steve never complained, he took all of it in stride. All of it. Morning sickness was no big deal, he loved having cravings to use as an excuse to eat whatever he wanted, he definitely had gained a little more weight than he probably should have by now, but that wasn’t a big deal either. The hormones only ever made him horney, if he became emotional he was easily soothed with kisses and cuddles from his alpha and he didn’t really have any aversions to food. Well, except for once at the beginning, he tried to eat shawarma with the team and promptly threw it up and hasn’t had it again since. Clint thought it was hilarious until Steve cried and then Tony made him wear a dunce hat for the next week.
But regardless, Steve loved being pregnant. Many times he’d told Tony that though he was not much of a traditionalist, he did love that he was good at the one thing an omega should be good at. And fuck if that wasn’t the sexiest thing he’d ever seen.
Steve was finally showing, the bump on his abdomen was already about an inch or two farther out than it had been before. Tony loved resting his hands over it, knowing their little pup was getting bigger and bigger each day. Steve’s body was softer than it had been, less toned, but he also had expected that. True to Tony’s word he had been encouraging Steve to eat more, and he definitely had been eating a lot more than he used to, seeming to feel hungry all the freaking time. He already couldn’t wear a good chunk of his clothes, mostly his pants. His waist had been getting bigger, definitely but he could still get away with his shirts. Unknown to Steve, Tony was planning on taking him on a little shopping trip today. His omega deserved the best, and he was going to spoil him with all the clothes and baby things he wanted.
Tony was currently on his way home from work. Thankfully there were only a couple more days of so many meetings and so much paperwork left before Pepper was officially CEO, and Tony could take a step back and spend more time at home with his mate. He didn’t want to miss a second of his beautiful glowing omega’s progression through this pregnancy. Steve was overjoyed when he found out, since he'd been having a harder time with Tony leaving, he was becoming very clingy (which Tony loved). He hadn’t planned this shopping trip, but earlier Steve had texted earlier saying his favorite pair of jeans didn’t fit anymore. So of course, when given an opportunity he was going to spoil his mate.
When he got home, he walked through the door of their living room, and he followed the scent of his happy omega to exactly where he expected him to be. Steve was unpacking some of the supplies they had already gotten for the baby in the room they’d chosen as their nursery. The room was a good size and the two of them had already ordered all of their furniture, so all that was left was to rearrange it until they were happy. Steve was playing an old song that he heard once when he was trying to listen his way through decades of music. It came out after he’d gone down with the plane but… it reminded him of his mother. So it had been one of the first to come to mind when he found out about Baby Bean. And yes, that is what they were calling them. Steve picked it, and it stuck immediately.
Steve was sitting on his knees putting some newborn clothes into the dark brown wooden dresser under the window, softly singing along to the song.
“See the pyramids along the Nile
Watch the sun rise
From the tropic isle
Just remember darling
All the while
You belong to me.”
Tony leaned against the door frame to watch him. He loved to hear his mate sing. It genuinely blew Tony’s mind how Steve really had no idea how perfect he was. How perfect he was at everything. He was perfect as a superhero, he was perfect as a lover, he was perfect as an omega. And he just did not get it.
But that’s okay, it was his job to tell Steve every day for the rest of their lives.
“See the marketplace
In old Algiers
Send me photographs and souvenirs
Just remember
When a dream appears,
You belong to me.”
He chose that moment to enter quietly. He rubbed his hands down Steve’s shoulders, leaning down to kiss behind his ear. “I love listening to you sing.”
Steve chuckled, “I’m glad someone does.”
“Oh that’s bullshit, you have a beautiful voice.” He shook Steve gently, “Don’t act humble.” Tony sat down next to Steve. He picked up one of the tiny onesies in the box, an adorable little tan and white one that said “Daddy’s Littlest Love”. He couldn’t wait to see their little pup in it.
“That’s one of my favorites, but do you want to see my number one favorite?” Steve nudged him with his shoulder.
Tony nodded, accepting the one Steve handed him. As soon as he saw it his eyes filled with tears. It was an adorable red and gold sweatshirt with matching pants and a shirt that said, “My Daddy Is Iron Man” with a little, simplified version of the arc reactor underneath.
“Where did this come from?” He looked back at Steve, holding the outfit to his chest.
“Clint, of all people.” He laughed, “while I was in the kitchen earlier he randomly dropped a box with this one and one other one from the ceiling vent.” The next one he held up was the same thing but a Captain America theme.
“That one is definitely my favorite.” Tony said softly, running his thumb over the little shield on the t-shirt.
Tony helped Steve put away the rest of the box before pulling his mate up to his feet. As soon as he was standing he pulled the blonde into a hug. He placed his hand on Steve’s cheek to pull him in for a kiss and then crouched down so he could put his hands on Steve’s bump. He kissed right above Steve’s belly button before looking up at Steve again.
“And how is Baby Bean today?”
“They’re good, I didn’t have any morning sickness today, but I have been craving pizza. Do you think we could get some tonight?” Steve asked, like Tony could ever say no to him.
“Of course we can, baby. I was also thinking maybe I would take you shopping today.” He looked at Steve with his eyebrows raised.
Steve got an excited look on his face, “Really?”
“Absolutely,” Tony looked around the room. “We can get anything else we need, some toys, maybe some clothes for you, too? I know you said your favorite jeans didn’t fit anymore.”
“That would be amazing, Tony.” He leaned forward with a sweet smile on his face. He bumped noses with him, and whispered softly, “I appreciate you.”
Tony didn’t think anyone in the history of ever had loved someone as much as he did Steve. He pecked him on the mouth and pulled him to their room so he could change.
Steve changed out of his sweats and into his last pair of jeans that buttoned. On his way to brush his teeth he paused in front of the mirror in the corner, turning sideways to inspect his body. He was thrilled to see his baby growing inside of him, he already felt connected with them from the moment he knew about them. He loved being pregnant.
Happy picked them up from the tower to go to a Macy’s store nearby. There Steve picked outfit after outfit for himself, as well as getting some comfy clothes and pajamas. Tony insisted he buy more for when he was bigger, despite the fact that they would be making more shopping trips then anyway. They picked up a new blanket set for the bedroom and then loaded all of the bags into the car before heading over to their favorite baby store, where they bought even more clothes for the baby along with some toys and supplies like a baby bath and more sheets and blankets for their crib and the baby’s room. After they finished there they went to IKEA to look for baby related furniture to be delivered to the common floor.
Hours later when they finally finished they ordered pizza to meet them at the tower along with a chocolate lava cake from a nearby restaurant at Steve’s request.
They got all of the bags set in their respective rooms before sitting in the living room to watch the tv show they had recently gotten into and eat their pizza and cake. When Steve was full and the food was gone they adjusted their seating. Steve laid back against the couch and Tony settled with Steve on his chest. They dozed on the couch together, Tony’s hand resting on Steve’s belly and the blonde’s over Tony’s heart.
They woke up about an hour and a half later and decided to go to the bedroom to change back into pajamas. Steve wore some new sweats and a shirt that fit perfectly.
They made the bed with the new bed set and cuddled in to put their show on in the bedroom instead. Tony took the opportunity to make out with his mate while he had it, which Steve obviously did not object to. Tony was just going to leave it at that, not wanting to push his mate too far, but to his surprise Steve was the one who took it further.
He threw the blanket back just enough so that he could wiggle out of his sweats and climb on top of Tony, breathily asking if he could ride him. Tony almost choked on his own spit when he heard that and eagerly tapped Steve’s hips to prompt him to lift up so Tony could shove his pants down. Steve’s slick was already getting all over Tony’s abs and crotch and if Tony’s cock hadn’t been hard before it certainly was now.
Without any warning Steve lifted himself up and lined up Tony’s dick before taking it all in one go. Tony shouted, trying not to come just from that. Steve moaned at the feeling and stopped for a moment to let his walls adjust. Tony placed his hands on Steve’s bump again. Steve covered Tony’s hands with his own before taking a deep breath. He raised himself up again and he and Tony got into a good rhythm of thrusting and bouncing. Both of them were either moaning each other's names or gasping. When they both finally came, Steve collapsed on top of Tony. Both of them were panting and trying to catch their breath, and Steve let out a weak laugh.
“Fuck I love pregnancy hormones.” They both laughed before Steve climbed off of the smaller man and cuddled in close with his nose nuzzled against Tony’s bonding mark. “And I’m definitely not getting dressed again, that’s like the fifth time today.”
“Baby, I will never be opposed to you being naked in bed with me. Or really just naked all the time. The point is, that’s fine.” They stayed cuddled in their bed like that until they both fell asleep, but not before they exchanged a quick goodnight kiss.
