Until (Little) Death Do Us Part

Summary:

When the demon Crowley invites himself as Aziraphale's plus one for Aziraphale's sister's wedding, who is he to object? They may not have known each for long (has it only been a few days? Feels longer), but it will certainly make it easier to endure having to spend time with the rest of his family.

Plus, this mean he will get to have mind-blowing sex again. And again. And again.

Notes:

This is a follow-up to my fic A Little Help From A Fiend

I usually wait with posting until the fic is done, but I got impatient. (And I wanted to post something for my "writing anniversary" -- thank you to everyone in the Bar that cheered me on when I started with my first fic 2 years ago)
Which might turn into a huge mistake, but hey, this is basically an excuse to write a bunch of smut, so what can go wrong? hahaha

Thank you so much Roo for helping me with beta so quickly! <3

Credit for the title goes to Arvy haha
I know you probably meant it as a joke but I couldn't resist xD

And of course, thank you Janara for always being so supportive <3<3<3

Chapter 1: Train Wrecked

Chapter Text

“Thank you again for your assistance, Eric.”

“Don’t mention it.” The unexpectedly young-looking man smiled. Aziraphale would never have guessed he was a demon if they had met on the street. “This is the closest to a vacation I’ve had in ages.”

Aziraphale found himself fascinated by the peppy young man currently carrying around one of his cats, Penelope. All three of them had taken to him instantly, following them around as Aziraphale had shown him around the flat.

“Any questions before I go?” He tried to tamp down the excitement over seeing Crowley again. It had only been three days since that first meeting and Aziraphale’s life was forever changed, but it felt like it had been much longer than that. Since then, they had talked briefly over the phone and texted a few times, but it had only made him more eager to see him in person again.

“Nah, mate, I think me, Penelope, Pepper, and Persephone got it from here.”

“Splendid.” Eric may not inspire the same immediate sense of trust as Crowley had, but hearing the contented purr from Penelope certainly alleviated most of Aziraphale’s apprehension. “But please, feel free to text me if something does come to mind.”

Eric scratched Penelope between her ears, making the cat relax further into the crook of his arm. “D’you want me to send you updates?”

“Updates?”

“Yeah, you know. Pics, and stuff like that.”

“Oh.” Not quite what he would’ve expected from a demon, but he certainly wasn’t going to complain. “How thoughtful of you, Eric. Yes, I would love that. Thank you for the offer.”

“I know how it is. I’ve got myself a hellhound puppy, and I miss the little bugger when I’m away.” Eric winced. “Uhh, please don’t tell Crowley I said that. Technically he’s not mine, but you know, it’s difficult to not get attached when you’re supposed to oversee their training.”

“Yes, I can imagine.” He smiled. “I doubt Crowley would hold that against you, but I promise I won’t tell.”

Eric gave him a peculiar look. “How long have you known each other, again?”

“Ah.” Aziraphale didn’t know how much Crowley had divulged about them. “Our acquaintance is quite recent, but it feels like we’ve known each other for far longer.”

“Right. Sure. Anyway, you should be going. Crowley will be here any minute.”

Aziraphale had been utterly disappointed to only find Eric outside his door earlier, expecting Crowley to be in his company—but apparently, he’d had some other business that had kept him from making it in time.

“Yes, quite right.” As if on cue, Aziraphale’s phone chimed with an incoming text.

 

Hiya angel, I’m outside the shop. Come down when you’re ready /C 

 

The smile came unbidden. It had indeed only been a few days since Crowley entered his life and took him by storm, but the demon had been on his mind ever since. Their tumble in the summoning circle had given him new insights about himself and made him want to explore further. Test his limits. But the deliciously rough parts of their sex act weren't what had lingered in his mind. He certainly had revisited those memories too, late at night with a fist around himself—but what had truly stayed with him was the soft moments. The sweet words, the cuddles afterwards. It had been quite surprising, coming from a demon.

Then again, it wasn’t as if he’d met a demon before. He had no idea if that was standard procedure, maybe Crowley always did a little extra for his clients. He probably did.

What Aziraphale did know, though, was that he wanted all of it again—both the rough and the soft—and it fascinated him how easily Crowley had read him. How he had given Aziraphale things he himself hadn’t even known he desired.

“Oh, I almost forgot. Crowley told me you wanted guacamole, you can find that on the top shelf of the refrigerator. He neglected to mention what flavour of nachos you prefer, so I went ahead and bought three different kinds. They’re in the pantry. You can of course help yourself to everything in the kitchen. And there’s a bakery right across the street —“

“Aziraphale?” Eric interrupted him with an amused grin.

“Yes?”

“Go. We’ll be alright.”

Here he was, about to leave his cats and his flat in the hands of a demon , and all he worried about was making sure that said demon would be comfortable during his stay. 

“Yes, yes, of course.” Aziraphale grabbed the handle of his probably overpacked suitcase. “I’ll see you Sunday evening, then.”

“Yup, we’ll be here. Have fun!”

After one final look at his cats, Aziraphale headed downstairs and outside, his heart starting to beat faster at the thought of seeing Crowley again.

“There you are.” Leaning against a black car with his arms crossed, Crowley smiled as Aziraphale approached him. It was just a small thing, but it still made Aziraphale happy to be the current recipient.

Crowley was wearing clothes similar to last time; tight jeans that bordered on indecency (not that Aziraphale had any objections to that, mind), a Henley with all three buttons open, showing off a tantalising amount of skin and just the hint of chest hair—and completing the ensemble, a form-fitted blazer jacket. All of it in black, of course.

“Here I am.” Aziraphale understood the necessity of wearing dark glasses when he was out in the open, but he dearly wished that he could see Crowley’s extraordinary eyes. “I’m sorry to keep you waiting.”

“Aziraphale.” Crowley straightened and pushed off the car. “I only texted you a few minutes ago.”

“Ah. Yes, that’s true.” He stopped in front of Crowley, unsure how to proceed next. 

Last time they met—the first time they’d met—Crowley had shagged his brains out, and Aziraphale wasn’t sure what the rules, or expectations, were now.

“Here, lemme take that off your hands.” Crowley stepped closer and grasped the handle, his fingers brushing over Aziraphale’s in the process. He smiled when Aziraphale let go, but didn’t step away to stow the bag. “Something on your mind, Aziraphale?”

“Am I allowed to kiss you?” Aziraphale blurted out, once again wishing he had an unobstructed view of Crowley’s eyes.

Despite the glasses, Aziraphale could tell that his question caught Crowley by surprise.

“Yeah, of course. Why wouldn’t you be?”

“I…” The question suddenly felt rather silly. “I don’t know. It seemed like a different kind of intimacy compared to the one we shared in my living room.”

“Fair point, I guess.” A cheeky grin widened Crowley’s mouth, showing a glint of teeth. “But since I assume we’re gonna act as a couple at the wedding, we might as well start now, if you want to.”

For some reason, Aziraphale had foolishly not thought that far ahead—that people would assume Crowley was his partner, and what that in turn would entail as far as his family was concerned.

Too late to worry about that now. It might even make this whole thing better than he had previously imagined.

“I think I do,” he said, latching on to the lapel of Crowley’s jacket. Not wanting to make a big deal out of it, he kept the kiss light and quick, a simple press of lips against lips. “Hi.” With a shy smile, he took a step back.

“Hi, angel.” A slight frown momentarily appeared on his brow, vanishing before Aziraphale had time to react. “Best we be off now, though.”

“Yes, of course.”

The ride to the train station was quick—quicker than it should’ve been, and Aziraphale found himself holding on for dear life as they sped through the streets of London. He was still feeling a bit wobbly when they got on the train to Paris.

“This way, Aziraphale.” Crowley led them towards the end of the train, stopping in front of a door that shouldn’t have been there.

“What’s this?”

“Seems like this train has an extra carriage, just for us.” Crowley grinned. “Gotta travel comfortably.”

With Crowley opening and holding the door, Aziraphale stepped inside. And was stunned.

He wasn’t sure what he had expected, but the extravagantly furnished room on the other side of the threshold certainly exceeded his expectations. The interior reminded him of a fancy suite at one of those posh hotels he would never afford to frequent. 

“Crowley…” 

Wide-eyed, Aziraphale took in the muted colours on the walls, the elegant sofa in black, and the steel coffee table accompanying it. But the pièce de résistance was the spectacular bed on the other side of the carriage, the frame wide enough to stretch along most of the back wall.

“Like what you see?” Closing the door behind them, Crowley took the suitcase still clutched in Aziraphale’s hand and put it on the sofa. “Fancy some champagne to start things off?”

“You did this for me?”

“Like I said, I like to travel comfortably.” With a lurch, the train started moving. Crowley took off his glasses and threw them onto the table. “But the bed I added with you in mind.”

Aziraphale wasn’t stupid. He had guessed as much, but hearing it out loud had his heart thumping with anticipation.

“I was hoping you’d say that,” he said, sounding as breathless as he felt. 

He unconsciously licked his lips when Crowley turned to look at him, aiming those fascinating eyes in his direction. Like with their first time together, in the summoning circle, he felt special to be the centre of the demon’s attention. He desperately wanted to believe he was special. He desired it. Needed it. 

“So that’s a no on the champagne, then.”

And just like before, Crowley wasted no time. Aziraphale found himself pressed against the door, Crowley’s hot mouth on his.

“Clock is ticking, angel. Let’s get you naked.”

Expecting the same efficient treatment as last time, it surprised Aziraphale when Crowley’s nimble fingers started working on the buttons of his waistcoat. Following his lead, he shrugged off his coat and carelessly let it drop to the floor, too focused on the goal of feeling Crowley’s hands on his body to care about wrinkles.

“Satan, you’re so adorable in these ridiculous bow ties of yours.” One hand tugging on said bow tie, Crowley tipped Aziraphale’s head to the side to nip at the skin just above the collar. “I think I’d like to tie you up with one of them sometime. Have you completely at my mercy.” He bit down harder, making Aziraphale gasp. “But not today.”

“Yes.” Aziraphale moaned at the thought.

The rest of his clothes dropped to the floor in quick succession as they made their way to the bed, with Aziraphale sighing in delight when his back hit the luxurious sheets. He felt gloriously indecent lying there, naked, staring up at the still fully clad demon looking down on him, something feral and greedy in his eyes.

“I have you all to myself for two hours, angel. Whatever should we start with, hmm?”

Aziraphale didn’t need to think about it, already sliding off the bed to kneel in front of Crowley. His breath ragged with want, he looked up at Crowley from under his lashes.

“May I?”

The need to be touched was still there, waiting, but another lust-driven craving decided to take precedence.

Arching an eyebrow, Crowley smirked. “Please, help yourself.”

His teeth digging into his lower lip, Aziraphale almost reverently took hold of the snakehead-shaped buckle of Crowley’s belt, carefully sliding it out of the loops securing it around the demon’s narrow waist. A tantalising image flashed through his mind as he let it drop onto the carpet-covered floor—perhaps it too could play a part in a future encounter? It could become just as useful as a bow tie. 

With that idea lingering in his mind, he made quick work of the fly on Crowley’s jeans, no longer having the patience to take things slow. A wanton moan slipped out when he saw that Crowley wasn’t wearing anything underneath.

The thick, hard cock felt heavy in his hand, an enticing weight he hoped to get much better acquainted with during the coming weekend. He felt himself clench around nothing, remembering how it had speared him open only days ago—and would do so again. Soon.

But first, he needed a taste. Craved it. He licked along the underside of the shaft, and oh, it tasted just as good as he had imagined. Taking the head into his mouth, he sucked on it, dragging his tongue over the slit to savour the salty beads of precome. Hearing Crowley’s groan as he did spurred him on, taking his cock deeper.

“The mouth on you. Such a good cocksucker.” One of Crowley’s hands weaved itself into Aziraphale’s hair. “That’s it, angel. A little bit more.”

Humming, Aziraphale acquiesced. Crowley didn’t push, he simply let Aziraphale take the reins for now, but the demon’s words encouraged him to swallow him deeper with every push forward. To his disappointment, Crowley was too big for Aziraphale to take him all the way down to the root without gagging.

“Careful, angel. I can fuck your throat raw when you’ve gotten used to my size, but for now, I’m more interested in rough-fucking another hole.”

Aziraphale obediently slid off when Crowley gently tugged at his hair, feeling excitement pool in his stomach and own aching cock when he registered Crowley’s choice of words.

“Up.”

Crowley didn’t have to tell him twice; Aziraphale eagerly crawled up on the bed to settle on his hands and knees. The bed dipped when Crowley joined him, placing himself behind him. Expecting Crowley to snap him ready like last time, Aziraphale was startled when he felt Crowley spread his cheeks and lick the furled rim.

“My turn for a little taste.”

His arms buckled when Crowley’s tongue pressed inside, groaning into the luxurious cotton comforter underneath him.

“Oh God, Crowley.”

“Don’t use her name with me, angel. Or I will have to spank you.” 

Not giving Aziraphale time to react, Crowley dove back in. When his tongue dipped inside, Aziraphale could swear it reached further than what should be humanly possible—which of course made sense, since Crowley wasn’t human. He tended to forget that, despite all the wondrous things Crowley could do.

“Yes, that feels so good, Crowley. More, mooore.”

Aziraphale had never had a lover eat him out, never really feeling the urge to experience it—but with Crowley, he could see himself becoming addicted to the sensation. It felt glorious—and it was over too quickly, as far as he was concerned.

“Don’t stop, Crowley, please,” he begged when the demon straightened with a pat on his arse.

“Another time, angel.” Aziraphale heard Crowley snap his fingers, and in the next moment, he felt the head of Crowley’s cock against his wet, stretched rim. “Because right now, I’m going to fuck you senseless.”

Crowley gripped his hips and pushed inside in one fluid motion. The pleasure bordering on exquisite pain, spreading like tendrils through his body, Aziraphale threw his head back and let out a high-pitched mewl

Bending down to cover Aziraphale’s back, Crowley nipped at his shoulder. “Mmm, just as good as I remembered.”

Aziraphale shuddered as Crowley’s hands moved along his side, caressing his generous curves. One of them travelled forward to pinch a pert nipple and Aziraphale could feel Crowley smile against his skin when the spike of pleasure teased a drawn-out moan from him. 

“And so responsive.” This time when his teeth grazed the side of Aziraphale’s neck, they felt sharper. “So delicious, I could take a bite.”

Another shudder flowed like water down Aziraphale’s spine. Crowley was still pressed snug against his plush arse, filling him to aching. He had never seen the appeal of cock warming, but he was—pun intended—warming up to the idea like dry kindling set ablaze. Later, when his brain was back to semi-functioning again, he would suggest it to Crowley.

Perhaps Crowley could sense what was on his mind, because in the next moment, he could feel Crowley’s breath against his ear, “If we’d had time, I would stay buried inside you until you came untouched.”

Aziraphale wetted his lips, throat dry at the thought. “I would like that.”

“Mm, we’re going to have so much fun, you and I.”

Straightening, Crowley latched on to one hip again, his other hand threading itself into Aziraphale’s hair. He took a solid grip and pulled Aziraphale’s head back just the slightest. It felt like heaven.

“So, angel,” Crowley started moving, grinning wide when Aziraphale pushed his hips back to meet his thrusts, “do you need us to come up with a story for your relatives?”

“Relatives?” Aziraphale could barely think. Why was he supposed to answer questions when all he wanted to do was focus on Crowley’s cock pounding into him? “What relatives?”

Crowley chucked. “The wedding, angel. Who am I? A friend? Your boyfriend?” His voice pitched down to a low, seductive purr. “Your lover?”

The wedding. Right. That’s why they were on a moving train. 

Despite the large windows on both sides of the bed, Aziraphale barely registered the rushing-by scenery on the other side of the glass—he was too focused on Crowley and what he was doing to spare it more than a fleeting thought. Pressing his eyes shut, he struggled for a moment of concentration.

The simplest solution would be to have Crowley pose as his friend, but that wasn’t what he wanted. Besides, it was always easier to remember a lie that was based on truth.

“Not my friend,” he pressed out, panting between the words. One of his hands fisted the fabric underneath him when Crowley changed his angle, brushing against his prostate. “Yes, Crowley..!”

“Scream as loud as you want, angel.”

Crowley picked up speed, hammering into him now. Aziraphale was only dimly aware of all the sounds he was making, but since Crowley clearly appreciated it, he didn’t hold back. His orgasm hit him out of nowhere, and with a choked cry, he spilled onto the comforter.

The fingers in his hair let go, and in a blissful haze, he felt Crowley chase his own pleasure, only moments later stuttering to a stop, filling Aziraphale with his come. It was such a deliciously filthy sensation, having Crowley’s spend drip down his thighs. Aziraphale wanted to ask him to leave it, but before he could, the demon snapped them both clean.

Some minutes later, they were tucked under warm, downy bed covers. He sighed as Crowley pulled him against his chest.

“Not a friend, eh?” Crowley’s fingers traced lazy circles on Aziraphale’s thigh.

Aziraphale caught the teasing note in his voice, but he still felt an urge for clarification. 

“Not only a friend.”

“You want to be able to be a bit naughty in public, is that it?” Crowley emphasised the ‘naughty’ with a nibble on Aziraphale’s earlobe. “I bet your family is a bunch of stuck-up, posh knobs.”

Aziraphale sighed again, both from Crowley’s ministrations and because the demon was correct in his assumption.

“My sister Uriel is the exception. She’s the only reason why I’m going in the first place. I want to be there for her. And her lovely fiancée Adrienne.”

Crowley hummed.

“As for the rest…” Aziraphale had always tried to make himself as invisible as possible whenever his father and cousins were around, but since meeting Crowley a new sense of confidence was brewing inside of him. “It could be fun to behave in a manner they would consider shocking, for once.”

“Sounds like my kind of gig. I like it. Lots of PDA then?”

“As much as you’re comfortable with.”

Crowley laughed and hugged Aziraphale tighter. “Oooh, that’s a dangerous thing to say, Aziraphale. Let’s decide right here and now that you’ll be the one to set the limits.” His fingertips drifted upwards, stopping just a breath away from Aziraphale’s spent cock. “Otherwise I might be tempted to give you a handjob during tonight’s dinner. Or perhaps suck you off while your dad holds his speech at the wedding reception.”

“Promise?” 

Aziraphale didn’t know if he was joking or not. That would be taking several steps out of his comfortable and familiar box, but perhaps he needed more excitement in his life. He could feel Crowley shrug.

“If you actually want me to, sure.” Crowley nosed the side of his neck. “I seem to be insatiable when it comes to my angel.”

“The feeling is mutual, my dear demon.” It was tempting to drift off to sleep, but they would probably be arriving in Paris soon. “I guess we should get dressed. Make ourselves presentable.”

Crowley raised his arm to check his expensive-looking clock. “Yeah, might as well.”

“It was a lovely way to travel.” Aziraphale turned to look at Crowley. “Even if it was over far too soon.”

“Aziraphale. Angel.” Crowley kissed Aziraphale’s pouting lips. “You have me all weekend. Both day and night.”

“I know, I know.” There was just one teeny tiny problem. He was starting to suspect it wouldn’t be enough.
