Chapter Text
Honestly, Steve should have seen it sooner.
It was about a month after Bucky and him had begun their ‘relationship’ of sorts. Bucky had been living in the Avenger (previously Stark) tower with whoever had decided to live with them at the time. Sometimes Bruce would join them for a break from sickness in foreign nations; occasionally Thor would pop in for a visit and comment on the status of his imprisoned brother. Obviously, Tony was always living there, if he wasn’t present much. Natasha and Clint would almost always be around, if they actually could drag themselves away from each other long enough to do anything but shove food down their throats. Both Steve and Bucky had been glad for the soundproofing on those days when the pair would come out with their hair sexed-up.
When Steve had first found Bucky, they were still in DC. Bucky had begun regaining his memories after about a week of HYDRA being shut down. He was scared. What Bucky didn’t know at the time was that he was pumped full of drugs, suppressants, and whatever else the scientists had thought could benefit ‘the asset’. A week of not having been frozen and not having the usual substances pumped into his system left Bucky confused and in pain. Steve had found him one day by a river. It wasn’t far, about ten miles out of town. Bucky wasn’t drinking or eating when Steve saw him, he was just staring at the water. When Steve approached him, Bucky stared at him for a good few minutes.
“I knew you.” He had said.
“Y-yeah,” Steve shakily replied, “we grew up together.” Steve hadn’t an inkling of clue about what to say to Bucky. Despite thinking about it for a week, he had come up with nothing that could make Bucky trust him again.
“Steve. Your name is Steve…” Bucky replied after more staring. That was the first of many memories returning.
Skip ahead a few days, the pair found themselves at Stark tower because Stark wanted to examine Bucky’s arm, which no longer moved the thumb. While he was there, Stark had suggested Bruce take a look and make sure Bucky was healthy, as well as to see if Bucky was really a Beta, or if he just smelled like it. Their examination proved to be helpful, as Bucky turned out to be an Omega who was just so full of suppressants that no one could discern otherwise. Steve said that he didn’t recall Bucky being an Omega, but Bucky also confessed later on that he had been hiding it from Steve. A week later, Bucky’s first heat since the 1940s hit, and it wasn’t pretty. With exception to Bruce, everyone around was an Alpha (everyone other than Tony, Bruce, and Steve when he could sneak it were denied access to the room for fear Bucky couldn’t handle the crowds). Thankfully for everyone involved, Bruce was the only one around when Bucky began to smell. Any Alpha would have gone crazy. Bruce got Bucky isolated successfully and Bucky began the longest heat anyone had seen. The normal Omega heat lasted for no longer than 5 days. Bucky’s lasted 10. After that, his heats regulated to once every 3 months for 3 days.
In agreement with the evaluations Bruce had done, Bucky stayed in New York, and of course Steve stayed with him. It took a year for Bucky to feel as normal as he could, and the Avengers couldn’t as for anything more. Well, all but one Avenger.
Steve was pining. He knew he was, but he couldn’t help it. Recently, Bucky had regained the last of his memories from just before he went to war with Steve. No one could figure out the inconsistency in the regaining of the memories, but for whatever reason the last time Bucky saw Steve, as a skinny 95 lbs asthmatic had been the last to come. For reasons Steve couldn’t comprehend, Bucky remembering that night made him want Bucky that much more. Bucky was in the same position. He had left one major thing out when sharing his memories. He was in love with Steve. Had always been in love with Steve.
When his memories first started coming back, he didn’t know why he left it out, but Bucky just knew it was important that he did. As the memories came back Bucky realized why he had left the tid bits of information out. Everyone in the 40s was a homophobe. Steve may have been his best friend, but no one could have convinced Bucky that Steve wouldn’t have turned on him. Bucky couldn’t loose Steve. So he hid his feelings.
Now, Bucky had realized that the 21st century was different, had seen it first hand when he and Steve caught Bruce and Tony making out in the lab one day. Other than Steve being a blushing 90-year-old virgin, he didn’t seem to care. Bucky still hid his feelings. Steve hid his.
The truth came out one fateful morning. Bucky had curled up with Steve after he had a nightmare. This was typical behavior, and half the time Bucky didn’t even have a nightmare. He just wanted to be next to Steve. Spooning, the couple fell into a deep sleep. So deep, that when they woke up, they both had the hardest morning wood either could remember. They also had both been dreaming about each other. Fifteen minutes and two love confessions later, Steve was balls deep in Bucky, hitting the right spot every time. Strung out in bliss, neither had remembered their lack of condom.
Until 6 weeks later.
It wasn’t really Steve’s brightest moment.
The first thing he had noticed was Bucky getting really horny. Steve never thought anything of it; their libidos had been through the roof lately. Steve’s, however, had calmed down so that they could enjoy other aspects of being a couple after three weeks. For a few weeks, Bucky’s had as well. Then, one day Steve had come home from a dinner meeting with the rest of the Avengers and a movie with Sam (he was looking to see if New York was a possible living arrangement) to find Bucky writhing in bed with his fingers up his ass. Slick was running down his thighs and all over his right hand. Steve walked in right as he came, cock untouched.
“Bucky?”
The man in question was too busy panting to respond.
That night kicked off a week of almost nonstop sex. At the time, the only thing that was eerie about it was that Bucky’s nipples were ridiculously sensitive. After the sex week, the morning sickness started. Or as Bucky later proclaimed, the constant all day horrible night and daytime sickness. The sickness in question actually began at night. Bucky had never been sick before this. That alone began raising their suspicions of other house members. Steve was too lovesick to notice, while Bucky was just flat out sick. 6 weeks later, Steve put the three things together.
“Holy shit!” he had yelled out of the blue while the couple was watching TV.
“What?” Bucky asked.
“You’re pregnant,” Steve blurted.
They sat in silence for a few minutes while the TV droned on.
“Oh my God I think I’m pregnant,” Bucky whispered, breaking the silence.
One trip to the pharmacy and a two-liter bottle of Coke later, a little positive sign showed on the stick.
“Holy shit,” Steve spoke.
“I think we need to have a talk,” Bucky said.
“I’m not getting rid of it” were the first words out of Bucky’s mouth.
“I would never ask you to,” Steve had said with sincerity.
“Do you… Would you even- I mean…”
“Bucky. Yes. I would like nothing more than to be a father with you. I’ve known you my whole life. You’ve been my best friend for most of it, and I’ve been in love with you since I was 15. I’m with you not just ‘till the end of the line, I’m with you through all the shit that we encounter along the way. I love you, and I don’t think anything would make me happier than raising a kid with you.”
“I love you too,” Bucky said, and hugged Steve deeply in the middle of the bathroom with a stick showing a small pink positive sign laying on the counter.
