Aziraphale was kneeling in bed with Crowley laid out on his back before him, his long legs up on Aziraphale's shoulders, his body jolting with every hard thrust.

They'd had sex almost every day for the past three weeks.

Crowley's hands were bunched in the sheets, his hair dishevelled, his eyes closed as blissful moans escaped him. Aziraphale couldn't tear his eyes away from his beautiful face. He looked so good like this, lost in his pleasure, almost delirious with it.

Crowley's eyes opened wide, entirely taken over by gold, and he let out a panicked noise. His hands flew down and his arsehole clenched so tightly around Aziraphale's cock that it verged on painful.

Convinced that he'd somehow hurt him, Aziraphale pulled free, looking down nervously at Crowley's stretched hole, which was pink and wet. But Crowley's hands had instead gone down to cover the black lace of his backless underwear.

"Don't look!" Crowley gasped. "Close your eyes!"

Aziraphale closed his eyes tightly, unsure what exactly he wasn't supposed to be looking at. He heard and felt Crowley shuffling away from him on the bed.

"Are you okay?" Aziraphale asked.

Crowley's voice cracked. "Did you see it?"

"See what? What happened?" But Aziraphale was already starting to suspect there must have been a wardrobe malfunction regarding Crowley's underwear.

"Really? You didn't see it? Please tell me if you did. I'd rather know." Crowley sounded like he was holding back tears.

"I was looking at your face. I didn't see anything, I promise. Did you escape your underwear?"

"Y- Yeah."

"Can I open my eyes now?"

"Sorry! Yeah, you can open your eyes."

Aziraphale opened his eyes.

Crowley was laying on his side, facing away from him with his knees up to his chest. He'd used dark magic to dress himself in his pyjamas.

Crowley glanced over his shoulder at him. "Sorry. It... it poked out at the top. I thought you saw it. You drew away."

"I thought I'd hurt you. You suddenly tensed up and cried out. That was why I pulled away," Aziraphale said gently. "I didn't know what was happening."

"Sorry."

"You don't need to apologise. It's alright. How are you feeling?"

"I'm fine. I just... It was a shock, that's all."

Aziraphale shuffled closer. He wasn't sure what to say, so he simply rubbed Crowley's back in a circular motion, hoping to help him feel better.

"I'm sorry," Crowley said after a moment. "I'm not really in the mood anymore. Sorry."

"It's alright." Aziraphale laid down behind him and stroked his hair. "I love you so much."

Crowley's breath hitched. "I love you too." He rolled over and buried his face against Aziraphale's neck.

Aziraphale wrapped his arms around him, holding him tight.

It'd been a week since 'the incident,' and Crowley was so scared of something going wrong again that he'd stopped asking Aziraphale to do him up the arse. He'd stopped wearing his backless, lace undies, opting instead for something more secure with better coverage and thicker material. Sometimes he didn't even take his trousers off.

They'd stopped using the blindfold. What if it fell off? What if there was a miscommunication and it was removed too soon?

They'd gone back to dry humping. Or sometimes Crowley used his mouth, his hands, or toys to get Aziraphale off, ignoring his own pleasure. It felt like a step backwards and Crowley hated himself for it, but he couldn't help how he felt.

They were woken early one morning by the ringing of the phone in the bookshop. Aziraphale leapt out of bed, completely naked, and then threw on his dressing gown before dashing downstairs.

Crowley rolled onto his back. He was hard. He put it down to morning wood, although it probably had more to do with the fact that he'd not had an orgasm in several days. They'd had sex last night but he'd focused entirely on Aziraphale's pleasure, and no amount of gentle coaxing from Aziraphale could convince him to do otherwise.

He lay there, staring up at the ceiling, angry at himself and at his cock, which despite everything was still eager for attention. He was hit with the sudden urge to get it over and done with, to just let Aziraphale see it. That would be better than it accidently making an appearance and shocking Aziraphale while they were having sex, right? If he'd already seen it and knew what to expect, then maybe it wouldn't be such a disaster if it did pop free again, and they could go back to how things were before. Crowley really missed having Aziraphale inside of him.

But it was a stupid idea which would probably backfire. If Aziraphale reacted poorly then Crowley would feel even more inadequate, and their love life would suffer all the more for it. But their love life was suffering anyway. Plus, they only had a few months left before they had to break the curse. Time was running out.

Maybe Aziraphale wouldn't hate it. Maybe he could get used to it. He might even learn to like it.

Aziraphale bounded into the room. "That book I told you about is ready for collection! I told them I'd be setting off shortly. I can get a taxi if you're too sleepy to drive?"

"Nah, I'll drive you."

"Oh, thank you, my dear!"

Aziraphale hung up his dressing gown on the back of the door and then went over to his chest of drawers. He pulled out some underwear.

"Er. Before we go. Real quick," Crowley said, his heart pounding. "Did you wanna see it? My... You know?" He gestured down at his crotch.

Hope flashed in Aziraphale's eyes. "Your cock?"

Crowley nodded. He might as well do it now while his dick was hard and he was feeling brave. He'd better get on with it though before it shrank back down into his body.

Aziraphale dropped the underwear he'd been holding to the floor, completely forgotten, and then gravitated towards him with a nervous smile on his face.

It was good they had plans – Aziraphale would be under no pressure to do anything more than give it a quick glance over.

"You don't have to do anything," Crowley said. "And we've got places to be anyway. Just figured, while I happen to have morning wood... It'll only take a second. Just have a quick look. Then it won't be such a big deal if you see it again by accident." He cut himself off. He knew he was rambling, and it had just occurred to him that if this went wrong they were in for a very awkward drive to collect Aziraphale's book. Perhaps this wasn't the best idea.

"It's alright," Aziraphale said gently. "It's only me. You've nothing to worry about."

Best get it over and done with, like ripping off a Band-Aid.

"Right," Crowley said, suddenly all business. "Listen, angel, this is important. You don't have to do anything you don't want to do, okay? Ever. You don't owe me anything. You can just have a quick peek and then we'll get dressed and go on our merry way. If the sight of it is too much, that's okay. It's not your fault if you find it a bit strange. It is strange. I just thought- I'll be less worried about it accidently coming out of my underwear if you've already seen it, that's all."

"Okay." Aziraphale gave him a warm smile and touched his arm, but Crowley didn't feel reassured. He was getting the impression that Aziraphale didn't think this could go wrong, naive angel that he was. Crowley hoped for both of their sakes that he was right.

Taking a deep breath, Crowley pushed the sheets down to his knees, revealing black silk pyjama bottoms, tented at the crotch. He wasn't fully hard, nerves getting the best of him, but he was close enough.

He couldn't quite believe he was really doing this. It felt like he was in a dream.

Aziraphale climbed into bed beside him, naked and already half hard, an excited look on his face which he was trying and failing to contain. Crowley worried that he wasn't taking this seriously enough, but he didn't know how to get through to him.

Crowley hooked his thumbs into his waistband. "Ready?"

"Yes," Aziraphale said confidently.

Now or never.

Lifting his hips, Crowley drew his pyjama bottoms down, revealing the thick, black underwear beneath, his cock straining against the material. And then he pulled his underwear down too.

He could feel cool air against his exposed cock. He refused to look down at himself, instead watching Aziraphale's face for any signs of distress or disgust, ready to cover himself up again. He fully expected Aziraphale to praise him no matter what. Little white lies to protect Crowley's feelings. But the truth would be written all over Aziraphale's face. They'd known each other for almost 6000 years, and Crowley could read Aziraphale like a book.

Aziraphale's eyes widened with surprise and curiosity, and then his face positively lit up. "Oh, Crowley. Your cock is lovely. Beautiful. Just look at you. The same colour as your scales when you're a serpent."

Crowley swallowed the lump in his throat, his eyes welling up. He let himself look down. There it was, just as he remembered it, and he couldn't quite get his head around Aziraphale's reaction.

It looked like a smooth tentacle, and it was charcoal grey, just like the skin around his cloaca. He didn't have any pubic hair, only a scattering of hard, red scales which matched the equally red and scaly bumps which went up his cock a couple of inches. If he had testicles, then they weren't visible. He assumed they were deep inside his body, but it wasn't like he had an anatomy guidebook to tell him what was going on down there. All he could do was compare himself to whatever humans had learnt about snakes and whales. Snakes for obvious reasons, and whales because they were the creature with a cock which most resembled his own. Now if anyone else compared their dick to that of a whale it'd sound like bragging – they are known for having huge cocks, after all – but he wasn't proud. Size wise, his cock was just as thick as Aziraphale's, but only for the first few inches from the base, after which it started to narrow. He didn't have a rounded cockhead like humans did, instead, his cock tapered at the end. It was a couple of inches longer than Aziraphale's at its hardest.

"Are you okay?" Aziraphale asked, breaking him out of his thoughts. "I really do like it, I promise. You have a gorgeous cock."

"Th- thanks," Crowley said, his voice trembling, his emotions getting the better of him.

There was worry in Aziraphale's eyes. "You do believe me, don't you?"

Crowley let out a laugh. "I- I do. I just... I never thought you'd like it."

"I like it a lot."

"But it's weird," Crowley said, his voice cracking.

"It's perfect. You're perfect." Aziraphale leant over and kissed him on the cheek and then the mouth.

Crowley looked down at himself again, and then, out of the corner of his eye, he caught sight of Aziraphale's cock, and it was rock hard. Aziraphale had seen Crowley's dick and he was even harder than he was before. Crowley couldn't believe it and he couldn't look away.

Aziraphale's hand was on Crowley's thigh. "Can I touch you?"

Overwhelmed, it took a moment for Crowley to find his voice. "If you're sure you want to. You don't have to. And... And your book. They're expecting you."

"The book can wait," Aziraphale said without hesitation.

Crowley laughed. "I never thought I'd hear you say that."

"Would you like me to touch you?" Aziraphale said with a smile.

"So long as you're sure."

"I'm more than sure. I can't wait to get my hands on you."

Crowley watched as tentative fingers reached out for him, and then fingertips were brushing lightly along his length, making him gasp. No one had ever touched him like this, save for himself, and he hadn't thought anyone ever would. The sight of Aziraphale's pale fingers against the charcoal grey of his cock felt wrong somehow, like Aziraphale was better than this, but it also had arousal pooling in his stomach.

"Is this okay?" Aziraphale asked, stroking him so gently that it had Crowley shuddering.

Crowley swallowed. "Yeah. Feels good."

A moan escaped him when Aziraphale touched the tip, and then Aziraphale's hand was moving down to the base. He started touching the scaly bumps, and Crowley tensed, ashamed. Although the skin of his cock felt similar to Aziraphale's for the most part, the bumps at the base were hard and smooth and surely off putting.

"Sorry, I know that part feels weird."

"Not at all," Aziraphale said, and then he looked up at him from under long eyelashes. "I was just thinking, I bet they'd feel incredible inside me."

Crowley made an involuntary noise. He could picture it, Aziraphale sinking to sit on his cock, taking him all the way inside and then bouncing on his lap.

Aziraphale smiled, fingers gliding over the bumpy scales before he removed his hand and sat back. Crowley instantly missed his touch. He was fully hard now, precum beading at the tip.

"Show me how you like to touch yourself," Aziraphale said.

Crowley stared at him in disbelief, his cheeks burning with embarrassment and arousal as he took hold of his cock and began to stroke himself with a firm grip. He'd seen Aziraphale do this to himself plenty of times. After pulling out of Crowley's mouth or his arse, he'd finish himself off with his own hand. Or Crowley's hand. Or rubbing himself between Crowley's arse cheeks or between his thighs.

Aziraphale watched him with parted lips, his eyes half-lidded. "Can I?" Aziraphale asked, reaching towards him.

Crowley nodded. He let go of himself and watched as Aziraphale's fingers wrapped around his cock, mimicking the way he'd held himself.

"Is this good?" Aziraphale asked, starting to pump him.

"Yeah," Crowley breathed. "Maybe a little tighter. Oh, that's it, that's perfect."

Crowley bit his lower lip, watching Aziraphale's hand move. He felt hot all over.

Aziraphale shifted position on the bed, briefly letting go of Crowley's cock in order to change his grip. Without thinking, Crowley let his cock twitch and move, seeking out his touch again. Aziraphale jumped.

"Sorry!" Crowley gasped.

"Don't be. I just didn't realise you have so much movement in your cock."

Crowley bit his lip. He'd been trying so hard not to let the thing flail around. He'd gotten too excited and forgot himself.

Aziraphale smiled. "Can I see it move again?"

Crowley didn't respond, his stomach in knots.

"I can make mine move too," Aziraphale said. He was kneeling, and suddenly his cock jumped, lifting up slightly before dropping back down. "I don't have as much movement as you, but I can give it a fair try."

Crowley's eyes widened in surprise. "I didn't know humans could move theirs at all," he said as Aziraphale made his cock lift and drop again. "No miracles?"

"No miracles. I assume all human cocks can do it. Mine's always been able to anyway. But only when I'm hard."

Feeling brave, Crowley made his cock lift too, and then it shifted from side to side. Aziraphale smiled and then took hold of him again, squeezing and stroking him until Crowley was gasping for breath.

"Ngh," Crowley whimpered, and he reached for Aziraphale's erection, but Aziraphale batted his hand away.

"Not yet, darling."

Aziraphale pressed him down into the bed, kissing him deeply while continuing to stroke him. "Can I use my mouth on you?"

Crowley made a garbled sound. "You don't have to."

"I want to. I want you in my mouth. I want to suck on you until you come down my throat."

"Ngk."

Still facing him, Aziraphale crawled down his body, and once his hands were either side of Crowley's hips he lowered his head and started to lick at him.

Crowley whined. His hands fisted in the sheets as Aziraphale slowly took him into his mouth. He watched as those lips slid up and down, wet and pink. Aziraphale's eyes were half lidded as he moaned around his cock, the vibrations adding to the pleasure.

How many times had Crowley watched Aziraphale put things in his mouth? Seen Aziraphale's eyes close in bliss as he moaned around another mouthful of something delicious? Crowley had always enjoyed watching him eat, loved seeing him enjoy himself, but that was nothing compared to this.

Aziraphale was clumsy at it, teeth scraping once or twice before he got the hang of it, but what he lacked in experience he made up for in enthusiasm. He was clearly enjoying himself. Aziraphale took him deeper and deeper, until Crowley felt himself press against the back of throat.

"If you keep doing that I'm going to cum," Crowley gasped.

Aziraphale let out a wanton moan around his cock and kept going. Crowley whimpered as Aziraphale continued to suck on him, feeling himself unravel while Aziraphale's head bobbed in his lap.

Crowley choked out a warning, and then he was cumming with a cry, his body shaking with it as Aziraphale held him down by his hips.

Aziraphale gagged for a moment, but then he was swallowing every drop, taking everything Crowley gave him.

Aziraphale lifted his head, gave Crowley's cock a few last licks, and then he grinned up and him. "How was I? Did I do it right?"

"Bloody Hell, Aziraphale. You were amazing. Ten out of Ten."

Aziraphale beamed proudly. "I'm glad you think so." He was kneeling now, his cock hard and red.

Crowley beckoned him closer. "Want you in my mouth. C'mon. Over here."

"Best not," Aziraphale said with a bashful smile. "I'm not going to last very long. I don't want to risk breaking the curse."

Crowley kissed him and pulled him in close. He snaked a hand between them both and started to stroke him, slow and languid at first, but quickly picking up the pace until Aziraphale was gasping and cumming in white streaks across Crowley's stomach.

They collapsed together on the bed, arms around each other, exhausted and sated. As they lay there panting, the enormity of what they'd done sank in. Crowley felt overwhelmed with emotion, tears coming to his eyes. He felt more accepted and more loved than ever before. He held Aziraphale even tighter.

"Are you okay?" Aziraphale asked, stroking his hair.

"Yeah. I just- I never thought I'd ever get to experience this. I love you so much."

Aziraphale kissed him. "I love you. Thank you so much for letting me see you. I know it was a difficult decision."

Crowley snorted. "I'd have shown you earlier if I'd known I'd get a blowjob out of it."

Aziraphale laughed and pulled him into another kiss. Crowley could taste himself on his lips.

While they lay there together, catching their breath, a comfortable silence fell over them. Until Aziraphale broke it. "Um. The book...?"

Crowley burst into laughter. "I almost forgot! Let's go." He miracled them both clean and then leapt out of bed, pulling Aziraphale with him. Aziraphale hurriedly got dressed while Crowley simply clicked his fingers, his own clothes appearing as if by magic on his body.

Miraculously they made it to the bookstore just in time, and it wasn't long before they were zooming back down the motorway towards Soho, Aziraphale clutching his new book in one hand, the other resting on Crowley's knee.

Crowley felt so happy he could cry.

Crowley went away for a few days to complete an assignment, and Aziraphale found himself so lost without him that he even opened the bookshop to the general public in an attempt to distract himself.

Aziraphale was sat in the backroom with a novel late one night when he heard the Bentley pull up outside. He raced to the front door.

Crowley sauntered into the shop and flashed him a smile, leaving Aziraphale feeling weak at the knees. He yelped in delight when Crowley pinned him to the closed door and kissing him fiercely.

"Missed me?" Aziraphale asked, clinging to him tightly.

"Fuck, yes. I drove back as fast as I could. Must've been going 110 the entire way."

"Naughty boy," Aziraphale said, pushing his thigh against Crowley's groin, feeling how hard he was already. Aziraphale was hopelessly aroused too, wet and hot between his legs.

By the time they made it to the bedroom they were already naked from the waist up.

Stood together at the foot of the bed, Aziraphale fumbled Crowley's trousers undone and then pulled them down his legs. Crowley was wearing the scantiest underwear he'd ever seen him in, all delicate black lace and satin. Aziraphale's fingers hooked into the flimsy waistband, and he looked into Crowley's eyes, seeking permission. He'd only seen him once, after all, and he didn't want to presume. Crowley nodded and then made a breathless sound when Aziraphale pulled down his underwear.

Crowley's cock was just as gorgeous as Aziraphale remembered it. There was no denying that it was unusual, but since when had anything about Crowley been ordinary? He was perfect.

Aziraphale touched him, explored him, enjoying the little keening noises Crowley made. He wanted to memorise every sound he made, every inch of his body.

Crowley kicked the rest of his clothes off, leaving himself completely naked. Aziraphale's eyes raked over him, drinking him in.

Every moment they'd shared so far was a gift, but this moment, with Crowley entirely naked before him, had the breath catching in Aziraphale's throat. Knowing that Crowley trusted him enough to be this vulnerable with him made his chest ache.

Aziraphale pressed him back against the wall, dropped to his knees and took him into his mouth, enjoying the taste of him, the weight of him on his tongue, the lewdness of it all. He loved how it felt to be on his knees for him, Crowley's hands in his hair.

Aziraphale felt wonderfully hot between his legs, and he squeezed his thighs together, wanting to be filled. He drew back, let Crowley's cock slip from his lips.

"Ngh," Crowley whined. "Angel. Please."

"I want you inside me. Can we?"

"Anything you want. Get up," Crowley growled, his eyes hungry.

Aziraphale got to his feet, and once Crowley had stripped him of the last of his clothes, he found himself being pushed backwards onto the bed. He shuffled up the bed and then laid back and spread his legs, desperate to feel Crowley push inside of him.

Crowley was staring at his cunt with longing in his eyes. "How should I-? D'ya want lube?"

"I don't think so," Aziraphale said, his stomach fluttering.

Crowley drew closer. "No. Look how wet you are." Kneeling between his legs, he ran a thumb across the slick folds and then pressed his palm against him.

Aziraphale gasped, pushing up against Crowley's hand, tingling all over, hot and aching. "Please, Crowley. I want you so badly."

Crowley lifted one of Aziraphale's legs, spreading him even wider, and let out a shaky breath. With his free hand, he took hold of himself and pressed forward.

Aziraphale felt the pressure against his hole, and then Crowley was sinking inside of him, stretching him open. Aziraphale had never done this before, never experienced a cock inside of him. The sight of it and the feel of it had him shaking with desire. Crowley seemed just as overcome, his eyes fixed on the place where they were joined together, an expression of awed arousal on his face.

They'd had so many first times together and there would be more to come. Aziraphale tried not to think about the inevitable last time, when the curse would break and they'd never be allowed to do any of this ever again. Best to focus on the here and now and savour every moment.

Crowley's breath was coming fast, and then he started to move, such short and hesitant little pushes.

Aziraphale rolled his hips to meet each thrust, his body hot with pleasure. He could feel the scaled bumps at the base of Crowley's cock with every grinding push, a reminder of just how deeply he was taking him. "You feel so good, Crowley."

Crowley made a desperate sound and sped up, eyes shifting from Aziraphale's face to where he was buried inside of him.

Aziraphale looked down, looked at where Crowley was thrusting into him, their bodies making wet and filthy sounds, and Aziraphale had to bite his lip and close his eyes. He needed to last. If he got too close Crowley would have to pull out.

"Angel, I'm close," Crowley whimpered.

"Come inside of me."

"Ah… Aziraphale."

Aziraphale watched Crowley's face as he came, the way his brow creased and he bit his lip, moaning and shaking as he pushed deep inside and stayed there. Aziraphale could feel him pulsing as he filled him up, and the thought of it had him trembling, dangerously close. He let out an apologetic warning and Crowley was pulling out, panting and grinning, and Aziraphale could feel his seed dribbling out of his wet hole, could tell that Crowley was watching it.

Crowley jumped from the bed, opened the bottom drawer of the dresser and then grabbed Aziraphale's white vibrator. He held it up, lifting an eyebrow in question.

"Oh, yes, please," Aziraphale breathed.

The bullet was pushed in through the mess of cum and his own slickness and then it was switched on, vibrating deliciously while Crowley pressed his entire palm against Aziraphale's sex, fingers rubbing at his clit. Aziraphale rocked against his hand until he was trembling with the force of his own orgasm.

They collapsed together in the bed, laughing and grinning, holding each other close.

"N- No! Stop!" Aziraphale gasped, trying to wiggle free.

Crowley immediately stopped what he was doing – enthusiastically and vigorously drilling Aziraphale into the bed – and pulled himself backwards, yanking himself free of Aziraphale's arse.

At almost the exact same moment that Crowley slipped free, Aziraphale came, his cock spurting across his stomach.

They both froze and then stared at each other in wide eyed panic.

Crowley let his eyes adjust, his supernatural sight focusing in on the swirling fog of the curse which still, thankfully, surrounded Aziraphale's entire body. Aziraphale lifted a hand, staring at it warily before relaxing.

"Thank fuck," Crowley said, allowing himself to breathe again. "You're still cursed."

Aziraphale let out a relieved laugh. "That was close."

"You and your prostate orgasms."

Aziraphale pursed his lips, but there was a twinkle in his eye. "You were the one pounding into said prostate with wild abandon."

Crowley grinned and then looked him up and down. Aziraphale was a dishevelled mess, his fluffy hair in disarray, his cheeks bright pink, and he was panting while covered in streaks of his own cum. Crowley started to stroke himself while looking at him.

Aziraphale watched him with half-lidded eyes. "That's it," Aziraphale breathed. "Cover me in it."

Crowley's hand sped up, and suddenly he was spilling across Aziraphale's stomach, their cum mingling together, indistinguishable despite all of their differences.

After they'd cleaned up they laid down together in bed. Aziraphale was unusually quiet, and Crowley looked into his eyes, concerned. "You alright?"

Aziraphale seemed startled for a moment. "I- Yes. I'm alright. It was just a bit of a shock is all. I'm usually quite good at judging when I'm about to- That one snuck up on me."

"It's alright," Crowley reassured him.

"I just don't want it to end yet," Aziraphale said. He paused and then added quietly, "I don't want it to ever end."

Crowley held him tightly. "I know. Me neither. So let's make the most of it, yeah? We'll always have these memories, and they're amazing memories."

"They certainly are," Aziraphale said with a smile, and then he kissed him. "I'm so glad we're able to have this, even if only for a little while. I love you so much."

"I love you too, angel."

Author's Notes:

So, while plotting this out a long time ago I couldn't decide what I wanted Crowley's cock to look like. But then I saw something online about how sightings of the Loch Ness Monster might actually have been sightings of whale cocks the entire time.

So then, naturally, I researched whale dicks: 'Their penis is also very agile, with two muscles attached to the pelvis giving it a good range of motion.'

Which naturally led to Crowley and Aziraphale comparing how much they can move their dicks.
