Natasha didn't think the pregnancy was going to be all easy but she pictured more issues adjusting her life around it and not how absolutely irritable it would make her feel. She was now about four and a half months along (when she and Steve did the math it was discovered she got pregnant after their very first time together and they decided to keep that bit of info to themselves, not wanting to encourage Tony with any more 'super' sperm jokes, which he still tortured Steve with) and was past the morning sickness stage. That had lasted about a month and she had to sit out of the missions because her stopping at random moments to vomit really did hinder things. That wasn't so horrible because at the time she really didn't want to be out anywhere and she was able to be the guy's eyes and ears at the tower while being conveniently close to the bathroom. Now she only had issues around certain foods like steak and cheeseburgers. The foods that all the guys in the tower just loved to consume on a daily basis. It was so bad sometimes she couldn't even be in the same room as them when they were eating. And if Steve had just eaten one of those things she couldn't stand to be near him until he brushed his teeth. But the food issues were starting to go away. Not all away but just a bit that she could function more normally.
It was too late though. She couldn't participate in missions anymore now that she was starting to show. In normal clothes she could hide her pregnancy but in her uniform she stood out like a sore thumb. The team was concerned that Natasha's pregnancy may make her a target to their enemies and while she didn't like it, she did agree. Plus, she was starting to feel more cumbersome. She wasn't big yet by any means and had only gained maybe five pounds but she felt bigger. She did do some light jogging, always accompanied by Steve or Clint, just in case. She always made sure to do stretches and even took up some yoga and made use of Steve's punching bags. She didn't like being idle and had to get some exercise somewhere.
Everything Natasha did though was only after she'd consulted her obstetrician. After she'd found out she was pregnant she'd needed to find a suitable doctor that could be trusted and wouldn't tell the world that the Black Widow and Captain America were expecting a baby. Pepper was ecstatic about the pregnancy and found Natasha the perfect doctor. The doctor really was perfect and Natasha took any advice the woman imparted to heart. So while she was still trying to stay in shape she did as the doctor said and made efforts to make sure she didn't overdo it and rested when she needed to.
It really did seem like things were starting to level out and Natasha was starting to get used to being pregnant but now she was feeling irritated at the smallest things. Like at this very moment she and Steve were eating a quick lunch before going to see the obstetrician. They were finally going to find out the sex of the baby and she was pretty excited but the feeling was quickly being hampered by Clint. He was just finishing his version of lunch which was a severely overstuffed peanut butter and jelly sandwich that had dripped jelly all over his fingers and he was in the process of licking them clean. Natasha had no idea why it bothered her, she'd seen him do the same thing countless times before but now she found herself gripping her water glass in her hand, seriously considering launching it at Clint's head. At a particularly loud slurp from Clint, she tensed her arm before she felt Steve's hand smooth over her shoulder to her neck and start to work his fingers against the strain there. Natasha felt herself relax instantly, forgetting her irritation. She was pretty sure Steve had developed the ability to tell when she was about to lose it. He had kept her from doing a lot of things that she knew she'd need to apologize for later. Steve always made it seem so casual as he reached for her hand or slipped his arm around her shoulders and the rest of the team had no idea how close they came on a daily basis to being knocked over the head with anything that was within Natasha's reach.
Now Steve pulled her up from her seat, grunting as he did so. Natasha smacked at him halfheartedly, smiling. She'd told him how she was starting to feel huge and he'd found it hilarious. Steve told her she could never be huge but teased her about it anyway. They cleaned their plates, said goodbye to Clint and were out the door to the doctor's office.
Once settled in the passenger side seat of her Corvette (Steve was the only one she allowed to drive it) Natasha turned to Steve, smirking, "Are you ready to lose the bet, Rogers? I already have several names picked out for little boys."
"I haven't lost yet and remember even if it is a boy; he still has to look like me. It could be a boy with your red hair and that would mean we both lose." Steve pointed out and smirked back.
"That would actually be pretty funny. Both wrong but both right at the same time. It'd really get the others going." Natasha laughed. They'd gotten the team involved with the bet, too. The only difference was they were playing for actual cash while she and Steve were playing for naming rights of the baby. Thor, Bruce and Pepper were betting on a little mini Natasha and Tony, Clint, Sam and Jane were betting on a little mini Steve.
"You know, I'll be happy either way." Steve said taking Natasha's hand.
"Yup and I will be too." Then added, "But I still want to win."
"Yea, you and your competitive streak!" Steve teased and let out a fake, drawn out sigh.
They arrived at the doctor's office and entered the building through the side door. The doctor knew they wanted to keep this as private as possible for as long as possible and did as much as she could to help them. The doctor would leave the door on the side open for them and they would go down the hallway to the same room every time where the doctor was typically waiting on them or would be there within minutes.
The doctor wasn't waiting for them today but there was an exam gown waiting on the table so Natasha started to strip off her clothes to be ready when the doctor came. She'd just slipped on the gown and taken her place on the table when the doctor knocked on the door and stepped into the room. The doctor chatted with them a bit and when Natasha broached the subject of her irritableness the doctor just reassured her it was normal, telling her it may be an on and off again occurrence through the rest of the pregnancy. Not exactly what Natasha wanted to hear but at least it wasn't her going crazy.
Finally they moved on to the sonogram. On the last sonogram Natasha couldn't identify anything that looked like a baby and only saw gray swirls. Steve claimed he could make out the baby without trouble and even tried pointing out the different parts to her but she just couldn't see it. She hoped she could today.
The doctor explained that she may be able to tell the sex but not to get their hopes up. That sometimes the baby just wasn't turned the right way or it was too early. When the image came up on the screen Natasha was ecstatic. "Aww Steve! That's our baby!" Natasha could see it perfectly now, the head and arms and legs. Getting pregnant was a total accident and she'd been pretty miserable the last few months but this moment made everything absolutely worth it.
The doctor leaned down and pointed at the screen, "I'm positive your baby is a little boy. If you see right hereā¦," the doctor indicated, "That is the penis. Congratulations!"
Natasha threw her arms up in the air in a cheer, "I'm winning!"
"I'm perfectly okay in losing." Steve said with the biggest grin on his face.
"Your baby boy looks to be normal and both of you are healthy. Unless you develop any problems or concerns I won't need to see you back here until next month. Would you like pictures of the baby to take with you?" The doctor said as she took down notes from the sonogram.
Natasha and Steve nodded their heads eagerly, still enraptured by the image of their baby boy on the screen. The doctor printed out the pictures and congratulated them again before wishing them well and leaving them alone.
Natasha was smiling ear to ear and began sitting up from the table to get dressed again but Steve was there, lifting her into his arms and kissing her hotly. She'd just wrapped her legs around his waist but he pulled back saying, "I know I said I had some tricks up my sleeve in trying to get you to marry me but I can think of no better place or moment than this one. Will you please marry me, Natasha?"
Natasha was so happy she could feel tears prickling her eyes. "Yes, I'll marry you!" And he kissing her again, pulling her into him and holding her tightly. She moved against him then becoming more aware of the position they were in. Mostly more aware of the fact that she was in a thin, skimpy examination gown and Steve's hot, hard body pressed against hers and in between her thighs.
Natasha rolled her hips into his and Steve responded instantly, sliding his hand under the gown and up to cup her breast. She rolled her hips against him again but realized that she was already so wet for him that she'd more than likely put a damp spot on his jeans. Natasha figured she'd save him the embarrassment and reached between them to undo his belt and fly before pulling his shirt from his jeans. When she started pushing his jeans down his hips to free his erection he lifted her away from him a bit to make it easier. His erection free she rubbed him up and down and sat up in his arms to guide him into her. Steve stepped back; knowing there was a chair somewhere behind him but didn't know how close it was. The back of his legs made contact and he lost his balance a bit causing him to sit down heavily, jarring his hardness into Natasha. She let out a pleasured cry and took into riding him in earnest. Steve gripped her hips hard and helped her to ride him, all the while kissing each other desperately. Feeling him hit her sweet spot, Natasha pulled away with a sharp cry before Steve could get his lips on hers again, trying to stifle the sound. He was still somewhat aware they weren't in private and didn't want anyone coming to investigate. Natasha tightened herself around his cock rhythmically and Steve let out a breathless "Fuck" against her lips throwing her into her climax and taking him with her. There was just something so incredibly sexy about Steve when he cursed. He very rarely did and if he was angry it only made it better but she'd never tell him that.
They continued sitting there, regaining their breaths and becoming more aware of the world around them. Natasha could feel the wetness from their coupling on her inner thighs and knew they should clean themselves up before they were discovered. She pulled herself from him reluctantly and went to the sink to wet a towel and cleaned herself off before getting Steve one too. Steve cleaned himself and refastened his jeans while Natasha dressed. When Steve heard voices in the hall he looked at the unlocked door where anyone could have walked in on them.
"We really need to learn to lock the door before we do these kinds of things." Steve pointed out with a smile.
Natasha ran her fingers through her hair and grinned, "That would be taking most of the fun out of it!"
"It was fun when Tony caught us?" He questioned with disbelief.
"Okay, no, it wasn't. Getting caught isn't fun but the almost getting caught is." She clarified. "Now let's get out of here so we can tell everyone all the good news!"
