Important:
I started writing this before the end of season 3. I don't know how things are going to turn out with Savitar, but this is assuming that Barry defeats him, and Iris doesn't die. Caitlin isn't Killer Frost either, and everyone's happy, for the most part. It's a year later, after Savitar's defeat. Barry and Iris are married and are finally ready to start a family.
This is more than just a oneshot fluff piece! This is going to be a full-length story, and it will cover everything from Barry and Iris trying to get pregnant to them becoming parents. I've seen a lot of pregnancy fics but none that are M-rated and that cover the entire story, so I decided to write this.
This is meant to be a very mature story. It contains explicit smut, but I really hate using that word to describe it. Not that I have anything against smut, but this really isn't about sex. It's about Barry and Iris starting a family. The sex scenes in this story are somewhat dirty, yes, but they're also meant to be beautiful. I know I could have just left it all out, but really, sex is kind of a fundamental part of making a baby, and to cut it out of the story would just feel inauthentic to me. Also, Barry and Iris have sex. They just do. It's implied in the show, and it's a healthy part of any adult relationship. It's normal, so I'm not going to pretend like it doesn't happen or justify it any further than I do in this AN.
I realize the story will get less readers this way, and some people may not be comfortable with those scenes, but I decided to keep them in the story.
There will also be a lot of awkward moments throughout the story. It's not a story of mine if it doesn't contain some awkwardness. To be candid, most of the awkwardness will stem from Caitlin's involvement in the plot. I'm sure you can guess where this is heading. To put it briefly, even with skipping the sex scenes, this story will require a certain level of maturity to read. This is reality, not just a fluff piece.
Warning: There will be conflicts in this fic. As I already said, this is not simply Westallen fluff, and not everything is going to work out the way Barry and Iris want it to. There's an actual plot, and it's not a particularly happy story, but I will PROMISE right now that it will have a happy ending.
Baby Fever
Iris couldn't help but notice it. They seemed to be everywhere she looked. The grocery store, the bank, just about every public place she went to. Hell, even a few of her coworkers were having them.
Babies.
Iris had never pegged herself as the type to suddenly come down with baby fever, but she couldn't deny it any longer. She wanted one. She wanted one with Barry. She wanted it so badly it hurt. She and Barry had spoken briefly a few times about starting a family one day. They both knew they wanted it, but Iris wanted it now.
She wondered if maybe it was too soon. She and Barry had only been married for a year, after all. On the other hand, they were both stupid in love. They both had stable jobs, and Barry had even gotten a significant pay raise this last year. Their loft was big enough and had an empty room that she couldn't wait to turn into a nursery. She had caught Barry staring into the room more than once, and she couldn't help but wonder if he was thinking along the same lines she was.
Most importantly, though, things were safe. Savitar had been defeated over a year ago, and since getting married, no new evil villain had stepped in to take his place. Sure, Barry had faced countless metahumans over the past year, but it wasn't anything the Flash and Kid Flash couldn't handle.
Iris didn't know why she was so nervous about bringing it up to Barry, though. It's not like they hadn't discussed it before. All their discussions, however, had been more about starting a family later. They hadn't even been full discussions, really. They had been mostly just brief little comments here and there. They hadn't exactly sat down and thought of baby names or made any real plans to start trying. Every time they talked about starting a family, it had been more geared towards the distant future.
Iris didn't see the point in waiting anymore, though. What were they waiting for?!
All of this was running through Iris's mind as she looked at Barry, watching him flash around the kitchen, making them breakfast.
"God, I wish they made kitchen appliances for speedsters," he chuckled, as he flipped a few pancakes, "I can flash around all I want, but I can't make things cook faster."
Iris laughed.
"It's good for you," she pointed out, "It's a good patience exercise, having to wait for things."
Barry laughed and shook his head, looking down at the stove. Iris bit her lip, staring at her husband's back. Now was as good a time as any.
"Speaking of waiting for things," she said slowly, "I've been thinking…"
Barry flashed around the kitchen, cleaning up the mess he had made. He came to a standstill then, setting a plate of pancakes in front of her.
"What about?" he asked casually, leaning over the counter, smiling at her.
Iris took a deep breath.
"About…starting a family," she said quietly.
The smile slid from Barry's face, and his eyes widened.
"Now?" he asked in surprise.
Iris shrugged.
"Why not?" she asked, "I've just been thinking lately. We've been married for a year. We're both financially stable. We have a good home. And most importantly, things are quiet in the city, and there haven't been any major Flash villains appearing lately. What are we waiting for, Barry?"
Barry gave her an uneasy smile.
"What if something happens, though?" he asked seriously, "What if a new Flash villain does appear?"
"That's always going to be a possibility," Iris pointed out, "Whether we wait or not, there's always going to be a chance that a new villain will rear his head."
Barry looked down at the counter.
"I'm sorry," he whispered.
"Please don't apologize, Barry," Iris said quickly, "I understand your responsibilities as the Flash. I know it's a part of you, and I love that part. The only point I'm trying to make is that the risk is always going to be there, no matter how long we wait, and we shouldn't let it scare us into waiting to start the family we both want and deserve."
Barry smiled sadly at her.
"I do want this," he said quietly, "I want it more than you know. I just…"
"You're just looking for reasons not to because you're scared," Iris said gently, "That's normal, Barry. It's not just because you're the Flash. Starting a family is both scary and exciting for everyone."
Barry gave her a small smile.
"I just don't know if I'm ready for that, yet," he said honestly, "To be a…a father."
Iris smiled and took his hand.
"Barry, if anyone's cut out for fatherhood, it's you," she said firmly, "You're going to be an amazing dad."
Barry squeezed her hand and smiled at her, tears filling his eyes.
"I've always wanted a family with you, Iris," he said happily, "It's all I've ever wanted."
Iris grinned at him.
"So, what are we waiting for?"
They did everything right, everything the way they were supposed to. They didn't just start trying right away. Iris stopped having her regular glass of wine every Friday night, and she went on a certified prenatal diet. No more pancakes. She stopped taking the special birth control pills Caitlin had formulated for her, and she and Barry had switched back to the friction-proof condoms they had used before. They weren't physically trying yet. Iris had read online that it was important to prepare your body first before getting pregnant, and she wanted to do everything by the book.
Caitlin noticed.
"You don't need them?" she asked in confusion, holding the usual contraceptive pills she normally made for Iris.
"No," Iris said, unable to keep the smile off her face, "I don't."
Caitlin frowned and set the pills down on the cortex desk.
"Why not?" she asked, "Are you and Barry…fighting, or something?"
Iris shook her head and smiled, trying not to laugh at the idea. She and Barry rarely ever fought, and when they did, it was usually about stupid little things. Their sex life had always been perfectly healthy—maybe a little too healthy, if anyone was asking.
Caitlin quickly put two and two together then.
"You're trying to get pregnant," she said quietly, her lips quickly turning up into a smile.
Iris grinned at her and nodded.
"Don't tell anyone else, yet," she said, "Barry and I want it to be a surprise, and well, we don't really want the extra pressure, especially from my dad. He's always been so excited to have grandkids."
"My lips are sealed," Caitlin said, smiling widely.
She flipped into doctor mode then.
"How have you been eating?" she asked quickly, "Are you taking any kind of vitamins? What kinds? How long have you and Barry been trying?"
"We aren't trying yet," Iris told her, "I've been off birth control for almost a month, and he's been using those…special condoms you gave us. I've been trying to get my body healthy first. I've been doing what all the books say, eating a lot of leafy greens and foods high in vitamin B. I've been taking a normal prenatal vitamin, but if you have anything better, that would be great."
Caitlin smiled at her.
"It sounds like you're doing everything right," she said, "I'll start working on a special prenatal vitamin for you. Barry's powers obviously change things, and you'll need something with a little more zinc in it most likely. Other than that, it sounds like you've done your research and are doing everything you should be."
Iris grinned at her.
"Barry and I are going to start actually trying soon," she said happily.
"I'm sure Barry's so excited," Caitlin said, smiling widely.
"He is," Iris said, nodding happily, "I think he's also a little nervous, though."
"That's normal," Caitlin assured her dismissively, "Most guys get nervous about it."
"Yeah, that's what I thought," Iris laughed, "I think he'll probably be more nervous when I'm actually pregnant. I caught him reading a pregnancy book the other day."
Caitlin laughed.
"Sounds like Barry," she chuckled.
She smiled warmly at Iris then.
"I'm so happy for you two."
"Is this comfortable for you?" Barry asked nervously, as he readjusted the pillow under Iris's hips, "I read it's supposed to help with conception. It's not scientifically proven, though, so I was a little skeptical about it. Still, I thought it was worth a try, but if it's uncomfortable, I can—"
"Barry," Iris laughed, cutting him off, "This is fine."
"Okay," he said quietly, letting out a shaky breath.
"You're so sexy when you're nervous," Iris giggled.
"I'm not nervous," Barry said, blushing indignantly, "It's just…it's not every day a guy gets to impregnate his amazingly beautiful wife."
"You're nervous," Iris persisted, "You don't have to be, though. Just do what you always do, Flash."
That simple phrase had the exact effect she had been hoping for. Whenever Barry was hesitant in bed, whenever he was unsure of himself or they were trying out something new, all she had to do was call him by his alter ego, and his confidence would come surging back to him. She didn't know if her husband was even aware of her little trick, but she knew one thing.
It worked every time.
Barry smiled and shifted in between her legs to lean over and kiss her. The kiss was slow and sensual at first, their lips moving together the way they always did. There was something different about it tonight, though. There was a buzzing excitement coursing through both of them as Barry kissed her. She could feel his manhood quickly growing beneath his boxers, and his breathing started to pick up as he deepened the kiss, his tongue gently teasing into her mouth.
A soft moan escaped Iris's lips through the kiss, and the sound seemed to spur Barry on. His hands trailed down her body, lingering for a moment on her exposed breasts before sliding down past her navel. His fingers played with the hemline of her panties for a moment, his mouth not leaving hers.
Barry moaned when Iris reached between them and palmed him through his boxers. He ground down against her hand, his breaths quickly turning into shallow pants.
"Iris," he sighed when she reached into his boxers to stroke him gently, "Not tonight."
Barry had always enjoyed the perks of having no refractory period. She often pleasured him at least once before he ever even entered her, but she knew why he didn't want that now.
He wanted to get her pregnant.
Barry's hands slid underneath her panties and removed them in one swift movement. His mouth quickly latched onto one of her nipples, and he spent a good amount of time teasing it with his tongue before moving to the other, seeing how many sweet moans he could elicit from her. For the fastest man alive, Barry was surprisingly slow. He always took his time, making sure to warm her body up and help her reach optimal arousal before proceeding. Barry had always been a selfless lover. He always put her pleasure before his own.
And tonight was no different.
Iris's breath hitched in her throat when Barry's mouth traveled lower, passing quickly over her naval until his mouth was where she wanted him most. He paused then, his hot breath on her center causing her desire for him to intensify.
"Barry," she whined, putting a hand on his shoulder.
Barry let out a breathy laugh. He always enjoyed teasing her like this, until she was aching for him. Finally, Barry's mouth went to where she needed it most, and Iris's eyes rolled back in her head. He was so good at this, applying just the right amount of pressure, as if he could read her mind. His tongue vibrated lightly against her center, and Iris saw stars. For such a sweet guy, Barry had a sinful tongue, and even after being married to him for a year, Iris still found it surprising how good he was when he did this for her.
"Barry!" Iris cried as she came, rolling waves of pleasure crashing through her, over and over again.
Barry gasped and pulled away from her then. He ran his hands gently along her inner thighs as she recovered from her orgasm. As soon as Iris could think straight again, she leaned forward and reached for Barry's boxers. She pulled them down gently, and his member sprang free.
Barry smiled at her, and Iris didn't know how someone so sweet could suddenly look so seductive with just one smile. Her bashful, fumbling, unassuming Barry disappeared in the bedroom, and instead, a different Barry took his place. Right here. This was where the Flash and Barry Allen met and became one person, and she was the only one lucky enough to get to see it. This Barry was hers and hers alone.
Barry leaned over her, bringing himself up to kiss her again. She could taste herself on his tongue, and it caused a warm feeling to pool low in her abdomen. Barry pulled away and paused then, his eyes inches from hers, both of them breathing heavily as they shared the same air. The two of them stared into each other's eyes, both feeling the same overwhelming excitement, as Barry lined himself up and slowly slid into her. No condom. No pills. Nothing between them. Just Barry and Iris. It was exhilarating.
It was beautiful.
Barry kept up a slow pace, slowly pulling out of her and then sinking back in. The pillow under her hips allowed for just the right angle for him to hit the right spot every time, and even if he was moving at an agonizingly slow pace, Iris could feel her pleasure building for a second time already.
"Faster, Barry," Iris whispered when he didn't speed up, "Faster."
"I'm getting there," Barry laughed.
She laughed with him.
They had grown comfortable with each other. Iris wasn't shy about telling her exactly what she wanted, and Barry was now perfectly comfortable with denying her requests, but only so he could drag it out longer for her, so he could make her release that much sweeter. Slowly, Barry picked up his pace, establishing a steady rhythm with his thrusts. Iris clutched the bedsheets as she felt her pleasure intensify, Barry hitting the right spot every time.
It was a surreal experience, having Barry inside her like this. It was different from any other night because this time, they weren't just making love. They were making a baby.
"Baaarry," Iris moaned as his pace quickened, "Faster. Babe, go faster."
"No," Barry gasped between thrusts, panting heavily, "No powers. I…I want to do this the normal way."
Iris's heart swelled at those words. Barry cared so much about this. He wanted to get everything just right.
Iris's grip on the bedsheets tightened as Barry thrust harder into her. Her hands left the bedsheets then and gripped his shoulders, her nails digging into his skin as she pulled him closer to her. Barry buried his face in her neck, and Iris soon felt the familiar swooping sensation low in her stomach, the pleasure continuing to build.
"Barry," she panted, their breathing in sync with each other's as Barry continued at the same fast pace, "Barry."
She reached her release like a dam breaking open, waves of pleasure crashing over her, and like a dutiful husband, Barry continued stroking her through her orgasm. He was then quick to follow her over the edge.
It was simple sex, but it was perhaps the best sex they had ever had, better than their wedding night.
And like their wedding night, Barry cried when he came. A single tear rolled down his face as he released into her with a sharp gasp. His hips stuttered to a stop as his seed started to fill her. It felt like heaven for both of them. It was euphoria.
It was perfect.
