Prompt: 23. Angst

The more Crowley is around kids, the more he wants them, and the more upset he is that there are no plans to have them. Relevant tags: male-presenting Aziraphale and Crowley, soon-to-be pregnant Crowley, soon-to-be mpreg, angst with a happy ending, yearning, South Downs cottage

Crowley wasn’t sure when he’d begun to hate the sound of a young child’s laughter. When he couldn’t stand the sight of the tiny baby clothes section of the department store. When the smell of diaper rash cream had started making him nauseous.

It hurt hearing and seeing and smelling those things. An infant’s cry sent a knife through his skull, and sure, the sound hadn’t been fun before, but it was absolutely unbearable now, and it filled him with rage instead of pity.

Prompt: 22. Hiding the Pregnancy

Aziraphale and Crowley are extremely effective at hiding Aziraphale’s pregnancy from their friends. Relevant tags: male-presenting Aziraphale and Crowley, pregnant Aziraphale, mpreg, South Downs cottage, outsider POV, hidden pregnancy

It had started in November. The weather had gotten colder, and Aziraphale had taken to wearing very warm, cozy, oversized winter jumpers. He was fluffed up with wool and fleece and it would have been entirely normal, given what the rest of them were wearing. Except that she remembered the previous two years, how Aziraphale’s only concession to the cold was a wool jacket rather than a linen one when he wandered about town. Otherwise, his typical dress shirt, waistcoat, and bowtie combination tended to reign supreme, varying only in the slightest nuances of similar shades.

Ava had commented on it, telling him that she liked the change, that he looked very nice in it. He’d beamed with a little twinkle in his eyes and said that after he’d made a comment about feeling a little restricted, Crowley had gone out to purchase it and he’d chosen it himself and, “Oh, isn’t aquamarine the perfect color for it?”

Prompt: 20. T4T

Sexual experimentation to feel more comfortable in their changing bodies with someone they trust becomes a lot more serious for Aziraphale and Crowley when Aziraphale becomes unexpectedly pregnant from it. Relevant tags: male-presenting Aziraphale, female-presenting Crowley, Aziraphale has a T-dick, Crowley has a penis, top Crowley/bottom Aziraphale, trans Aziraphale and Crowley, pregnant Aziraphale, human au, trans mpreg, aromantic Aziraphale, greyromantic Crowley, some mild gender dysphoria mentioned, friends with benefits, oral sex, cunnilingus, rimming, mention blow jobs and anal sex and hand jobs and wall sex and riding, vaginal sex, accidental pregnancy, induced lactation, non-graphic depiction of childbirth, queerplatonic relationship (QPR)

“But it seems we’ve found the solution right here.” When [Aziraphale] tilted his head in confusion at [Crowley], said smirk only grew wider. “We’re both hot, both horny, and both understand what it’s like to have a body that’s undoing years of changes and starting all over again. We’re friends, so why not add benefits?”

Aziraphale wasn’t sure that they were friends friends, but he was rapidly deciding that friendly was plenty enough to make friends with benefits a thing. His cock was certainly advocating for that rationalization, throbbing in his briefs.

“It’ll give us both some confidence in the bedroom while being the way we are now,” she continued. “It’ll make it easier to tell anyone else we take to bed in the future who has problems with the way we are to fuck right off, yeah? And we get our rocks off regularly until we manage to find someone else.”

Prompt: 19. Carbon Copy Kid

For better or for worse, Aziraphale and Crowley each birth their wife’s mini-me. Relevant tags: female-presenting Aziraphale and Crowley, pregnant Aziraphale, pregnant Crowley, pregnancy symptoms, vague discussions of childbirth, kids who are alarmingly like their mums

“Well, you’re very sweet and very good to me,” her voice rose automatically to override Crowley’s snarled protests, “so it makes sense that your child would be very good to me. Whereas yours is a bastard. That’s what you always call me, yes?”

“Because you are one,” she said sulkily.

“See? Of course the child would give you some trouble. But you like that I’m a bastard, don’t you.”

“Wouldn’t like you if you weren’t,” she replied, as if she hadn’t told her some variation on that at least twice weekly and had done so in her wedding vows.

“There, so that’s to be expected. It’s only a few more months, and then we’ll both be dealing with them.”

Prompt: 18. Labor and Delivery

Sure, Crowley could cheat the birthing process a little to make it easier for himself, but could he really, when he remembered why childbirth hurt so much in the first place? Relevant tags: female-presenting Aziraphale, male-presenting Crowley, pregnant Crowley, mpreg, Crowley and Aziraphale were friends with Adam and Eve, allusions to childbirth

“Anyway, if [Eve] ever found her way out of the afterlife, she’d give me the real definition of Hell if she figured out I cheated, so the natural way it is.”

“I still think she wouldn’t begrudge you a little pain relief,” Aziraphale pouted, but Crowley shook his head stubbornly.

“Nope, doing it in her honor. Not cutting any corners.”

Prompt: 17. Trying to Conceive

In which Aziraphale decides it’s his turn to carry their next little merbaby. A sequel to i’m in a winter mood, dreamin’ of spring now Relevant tags: male-presenting Aziraphale and Crowley, Crowley has a penis, Aziraphale has a penis and a vulva, intersex Aziraphale, genderfluid Crowley, top Crowley/bottom Aziraphale, pregnant Aziraphale, mpreg, merperson au, ‘vaginal’ sex, procreative sex, creampie

There were no sudden impetuses to switch based on Aziraphale lifting something heavy or being more ‘masculine’ than usual, but there were signs that the change was coming anyways. And while that would usually be celebrated, the anticipation of a new chance to make a child of their love, it made him a little nervous, as he was hoping to change things up a little for their fourth.

Which was why, when the kids were tucked away for the night and Crowley and Aziraphale were snug in their den, he hesitantly said, “I’ve been thinking we might try for another.” And before Crowley could say yes, he added, “And I’ve been thinking that it might be my turn to carry them.”

Prompt: 16. Weight Gain and/or Breast Growth

Crowley’s gained weight all over, which is fascinating. But what he loves most about it is Aziraphale’s fascination with one particular bit of him. Relevant tags: female-presenting Aziraphale, male-presenting Crowley, Aziraphale has a penis, Crowley has a vulva, top Aziraphale/bottom Crowley, pregnant Crowley, mpreg, Crowley has large breasts, blow jobs, tit fucking, vaginal sex

He looked damn good pregnant, in his opinion. Luckily Aziraphale agreed.

She agreed so much, in fact, that when Crowley slumped down the stairs, feeling his breasts bouncing with every movement, she dropped her saucer. Instantly, Crowley was wide awake, watching Aziraphale watch him, seemingly hypnotized by the sway of his chest.

Oh, she made it too easy. He was struck by the undeniable urge to tease her further. If she wanted his tits, she’d get them.

“Morning, angel,” he purred, stepping carefully over the remnants of her mug.

Prompt: 15. Pampering

Crowley’s due to give birth any day now, so Aziraphale is intent on pampering her. And on helping to make her life easier in future with a very focused massage. Relevant tags: male-presenting Aziraphale, female-presenting Crowley, Aziraphale and Crowley have vulvas, pregnant Crowley, hair washing, massage, perineal massage

Someone, his hands were those of a maestro, playing her body over and over again to make something beautiful, make her beautiful. She’d never felt so radiant as she did whenever he touched her like this, melted her back into her own body even as it grew to ever more alien proportions with the imminent birth of their child.

“There,” he said. He leaned down to kiss her forehead, and then he was gone.

When Crowley heard the faucet in their bathroom start up, she knew what was coming next. She oozed off of the table and collapsed gracefully to the floor, not bothering with the dressing gown close by.

As Aziraphale returned with a small bottle of massage gel, she automatically opened her legs.

Was thinking about what to do for the Ineffable Family February prompt “Surprise”, and of course the obvious thing was one of them discovering they’re pregnant, but then I watched the video of Seth Meyers talking about how his wife gave birth to their second kid so quickly, the kid was born in the lobby of their apartment building. And I thought, that’s certainly a surprise. Anyway, here you go.

Prompt: 14. Historical Setting

Two families with a big secret. A desperate need for an heir. Aziraphale and Crowley are thrown together as the only two who could maintain their families’ reputation and carry on their lineage. Relevant tags: female-presenting Aziraphale, male-presenting Crowley, Aziraphale has a penis, Crowley has a vulva, trans Aziraphale and Crowley, top Aziraphale/bottom Crowley, pregnant Crowley, human au, mpreg, historical setting, arranged marriage, mentions of feared transphobia, mild homophobia (from the parents), first time, vaginal fingering, vaginal sex, painful sex (that gets better), procreative sex, creampie

“If one is outed, then so is the other. A mutual ceasefire,” he continued, grin getting wider. “But with much more material benefits. Mr. Eastgate, Mrs. Eastgate, we accept your offer,” he said with only a glance at his wife. “Now, if we might have some discussion of a dowry…”

Aziraphale and Mr. Crowley sat in stunned silence as without even a pretense of soliciting their input, their parents arranged the rest of their lives right over their heads.

Once arguments had been had and agreements had been made, the elder gentlemen shook hands as their wives did the same. “Well Miss Eastgate,” Mr. Crowley said as turned from her father, “it’s settled. Welcome to family Crowley.”

Prompt: 13. True Forms

In the most sacred of times, lioness and serpent meet among the stars they call home. Relevant tags: female-presenting Aziraphale and Crowley, Aziraphale has a penis, Crowley has a vulva, pregnant Crowley, true form Aziraphale and Crowley, lioness Aziraphale, serpent Crowley, ‘vaginal sex’, procreative sex, all the space metaphors

When the urge, no, the compulsion to create made itself known in Aziraphale and Crowley, they knew there was only one way to do it properly.

A gentle kiss and their Earthly corporations dissolved, the physical and metaphysical molecules of their consciousnesses and their true selves floating up towards the stars where they’d met. A brief, joyous swirl together, then they were drifting away to enmesh with the constellations that best represented their inner selves.
