A/N: Dysphoria tw, trans man Arthur, pregnancy, smut.


Arthur had always wanted children. That was something he planned on in any relationship he had, no matter who he fell in love with and married. Even for those people he knew were only temporary because he could never see himself being with them forever, he would ask himself "well, what if someone got pregnant?" and the answer was always the same; Arthur would love the child that resulted more than anything else. He was determined to be the best father that ever was.

He liked dating women because there was a greater chance that they would want to carry their children, though he definitely preferred men sexually. When he met Alfred, Arthur knew he would make an excellent father, and he didn't care who had their baby so long as the two of them got to raise it together. They discussed it less often than one would think, considering parenthood was Arthur's priority. After deciding it was too soon to expand their family right after he married Alfred, the matter didn't come up for a long time.

For Arthur, at least, it was a sore subject. He was slowly coming to terms with the fact that he was a male that could bear Alfred's children. His husband was very supportive and promised to back Arthur up in whatever he chose, but insisted that being pregnant did not make him less of a man. Arthur was not sure if he could handle the dysphoria a pregnancy would cause him. How could he look down at a large, round belly and still call himself Arthur? It was a woman that has babies. That's what he was taught from his own birth. Then again, he was also told that he was female.

Alfred had met Arthur toward the beginning of his transition and knew how terrible his dysphoria could get. If having a baby made it worse, then he didn't want Arthur to do it. There were plenty of other ways to have children. Regardless of what they chose, they would both be fathers to their baby, so it didn't make a difference to him. Arthur's happiness meant the world to him.

It was in the middle of making love to his husband one night that Arthur made his decision final. He had stopped taking his oral contraceptive over a week prior to see how he would feel regarding the changes that would make to his body. Because he never felt the desire to go on testosterone, he and Alfred needed to use birth control, which consisted of both condoms and the pill. Arthur knew that he could get pregnant if they tried. If this is what he wanted, he could have it.

Alfred's tender loving kiss made Arthur beam and he looked up at his husband in awe. They could be a family. He put a hand on Alfred's shoulder, waiting for his long, gentle thrusts to stop. The blue-eyed man asked of everything was alright. Arthur nodded, smile growing wider.

"Let's have a baby."

"We're going to someday," Alfred replied. He pulled out of Arthur and laid beside him, positive that he wasn't going to finish now.

"No, love. Let's have a baby now."

Alfred grinned at his husband. "You're not serious, are you?"

"Of course I'm serious. If you think we're ready for a baby, too, I'd like us to have one - tonight," Arthur said.

Arthur's husband tried to argue that his dysphoria would return with a vengeance along with a slew of other things, but he wasn't about to hear it. He had thought it through and read up plenty on the subject. They had been married for two years and were financially stable. If Arthur wanted to go on hormones to transition soon, he wanted to have a child first. It was just simpler that way. Plus he has waited long enough to fulfill his dream of becoming a father.

"I want you to fuck me until there's a baby inside of me. Do you understand?"

"God yes."

With a lack of the poise he usually possessed, Arthur rolled the condom off of Alfred's cock and started teasing the tip with his tongue. He wasn't about to let his husband go soft now that he was being put to good use. Arthur pumped his husband's erection until he was fully hard once more. They were both thinking about impregnating Arthur, and the idea alone turned them on more than they thought it should.

Arthur straddled his husband's hips and lowered himself until Alfred's cock brushed his lips. The latter had forgotten how good Arthur's tight, wet slit felt against his bare skin, and this was only the beginning. He recalled having sex without a condom only a few times over the four years they were together. Of those several times, even fewer were instances of vaginal sex. Arthur preferred not to have sex like that more often than not.

The green-eyed husband rocked his hips softly so that Alfred's erection rubbed against his clit. He liked watching Alfred struggle to keep his eyes open so he could watch Arthur move on top of him. Arthur continued grinding against Alfred's cock until he was breathing heavily. He made tiny moans that had Alfred nearly on the edge, panting in want of release.

"Jesus Christ, Arthur, I think you're trying to make me cum now."

"No, no. Not yet."

Arthur positioned his husband's cock between his wet lips and painstakingly allowed him inside, inch by inch. By the time he was all the way in, Alfred was afraid he would cum early. He looked up at Arthur, whose back was arched in pleasure, and knew that he was the luckiest man to ever live. And they were going to have a baby together.

Unaccustomed to Alfred filling him in this way, Arthur began riding him slowly at first to get a feel for this kind of sex. It was much more stimulating than he remembered. Then again, Arthur could almost get off on just thinking about becoming pregnant with Alfred's child. That must have had something to do with it.

Alfred was moaning and whining already. He was always so noisy during sex, though he was trying to stifle the sounds he made. Arthur didn't want that at all. He wanted to remember the incredible, hot, loud sex they had on this important night.

"Oh, Alfred!" Arthur groaned quietly as he sped up a bit to get his husband going. "Fuck me harder with your thick cock!"

He responded by suddenly thrusting up into Arthur. "Like that?"

Arthur knew he could get his husband to fuck him mercilessly, the way he liked, with a little encouragement. He gripped Alfred's shoulders and started to ride him like there was no tomorrow without warning. They'd been married long enough to know exactly how they best had sex. It was only a matter of time before Alfred pulled out of Arthur once more, only to flip him on to his stomach, and resume fucking him into the mattress. Alfred hooked an arm under each of Arthur's shoulders so their bodies could not possibly get any closer.

"Is this what you wanted?" Alfred growled.

"Yes."

Alfred buried his prick deep inside of Arthur and held it there. "You want me to fuck you until you're pregnant with my child?"

Arthur swore he could have came when he said that. "Yes!"

His husband's voice was low in his ear. Arthur was already squirming and throbbing around his erection. "Once you're filled with my seed, I'm going to fuck you again." He slowly withdrew and slammed back inside of Arthur, which made the latter grunt. "And again." Alfred repeated the motion. "And again" This time, Arthur gasped loudly.

"Fuck me already, dammit!" Arthur demanded, tired of being toyed with. He was out of patience.

Alfred roughly ground Arthur into the bed with his next thrust, rapidly fucking him with the motion of a piston. This position had Arthur cumming in less than a minute with the friction this provided his clit. He melted into his orgasm as Alfred came behind, and into, him. Arthur grinned in his pleasure, feeling Alfred's cum spill inside him. That bout of shagging had been the best they'd had in a while.

Both breathing heavily, the husbands curled up next to each other, reveling in the amazing sex they had had. Alfred placed a hand where Arthur's uterus would be and began to stroke it lovingly. He cooed about their baby growing in his husband's womb, how much he loved them already. Arthur smirked knowingly to himself, but didn't bother to tell Alfred that he couldn't possibly be pregnant quite yet. It made Alfred happy to think he'd done his part, so Arthur wasn't about to take that away from him.

"We're going to be the happiest family ever," Alfred claimed in a quiet yawn.

"I think so, too."

Alfred was just about to pass out, but not before he corrected Arthur. "I know we are."

AAA

Alfred's brother Matthew already had two children, both whom liked to spend time at their uncles' house most weekends. Arthur adored the little ones, treating them no differently than he would his own children, and couldn't wait to give them both a baby cousin. He, Alfred, and Matthew would make breakfast in the kitchen every day their family came together. The little ones played nicely at the table so the adults could keep an eye on them, even though there was no need. They were very well-behaved for their ages of two and three.

"Hey, Mattie," Alfred said, prompting everyone to listen to him. "You know how me and Arthur have been trying to have a baby?"

Matthew, busy manning the stove, looked at him out of the corner of his eye. "Yes. What aboot it?"

"Well, take a look." Alfred tossed something his brother's way. Arthur only caught a glimpse and couldn't tell what it was. "I'm pregnant."

The elder brother examined what must have been a pregnancy test, Arthur assumed, and replied with a raised eyebrow. He threw the plastic strip back at his brother and moved to wash his hands. His children at the table cried out in confusion. "Nooooo! Only mommies can have babies, Uncle Alfie!"

Arthur didn't even flinch at the comment. It wasn't anything new to him, and they weren't taught to know any better. No harm was done, though Matthew still shot him a nervous look. He apologised as well.

"That's not always so, little one," Arthur said patiently. "Some special daddies can have babies too - like me."

Alfred chuckled. "I'm pregnant!"

The children protested again, complaining in giggles that Alfred wasn't a special daddy as Arthur was. "It's a joke," Arthur assured, snatching the pregnancy test away from Alfred to inspect it. He was impressed that he took the time to find a positive one just to make a joke.

"Well... the joke is on you, Arthur, because it isn't a joke!"

"What in God's name are you getting at?"

"The. Joke. Is. On. You." Alfred excitedly gestured at Arthur's abdomen with both hands, smiling like an idiot.

Arthur's face dropped in shock. "What? How did you do this?"

Alfred beamed more brilliantly, appearing to think himself clever. "It seriously sounds more creepy than it is, so it doesn't matter. Arthur, you're pregnant!"

Matthew offered a congratulations that was drowned out by his children's cheering. Arthur stared blankly at the test in his hand, and then glared at his husband.

"I swear to god, Alfred, if this is a joke -"

"It's not, I promise!" he said excitedly. "We're having a baby!"

Arthur started smiling uncontrollably as Alfred moved to wrap his arms around his husband, both of them approaching the point of bursting in to tears. They hugged and laughed while the children squealed in the background, even though they couldn't possibly understand what this meant to them. Alfred kissed Arthur sweetly and whispered something in his ear.

"We're going to be the happiest family ever, starting now."
