Chapter Text
Kai knew his demons would build a suitable nest for them, but he hadn’t expected this.
“We know this is your favorite mountain,” Soobin explained as Kai gaped at the massive glass prism sparkling in the sunlight on top of what was indeed his favorite mountaintop in the world. The one that felt like home, that looked out over gorgeous valleys and featured a network of hot and cold springs that were practically a built-in spa.
Kai had been planning to remain aloof, to make his mates earn even the smallest display of approval, but it was hard to school his expression when the den they had built was a feat of engineering he had never even imagined.
The den was made entirely out of glass but, as they flew closer, Kai realized it was almost more like the frame of a prism. The walls were all open, allowing them to fly in directly even though the air changed slightly as they entered. The air was still fresh, scented with the wildflowers blossoming in the meadows and forests outside, but it was regulated to be a comfortable temperature.
“Kai!”
Kai blushed as the rest of his mates appeared around the corner, shamelessly naked and glistening from…whatever they had been doing. Kai was pretty sure he had a good idea, and his traitorous heart fluttered as he realized they had truly made peace with one another for his sake. That they cared about one another enough to spend time intimately even when he was nowhere to be found. It was something he had always wanted so that he could ensure their flock was secure and peaceful, and they had made it happen for him.
“Look at you, pretty angel,” Yeonjun purred. He scooped Kai from Soobin’s arms and plundered his lips in a very thorough kiss. Beomgyu and Taehyun came to steal their own kisses too, their hands running possessively over Kai’s bare skin as they welcomed him to their nest.
And, heaven help him, it already felt like home even though Kai had barely seen any of it. The mountain was just such a special place for him, the place where he felt most completely himself, and the glass of the structure was subtle enough to let his favorite parts of the scenery shine. He loved the way the prism shape elongated the plateaued mountain top into a sharp, gleaming point, and how seamless the open walls made the whole space feel.
“This is the main living space,” Beomgyu explained, gesturing out to the massive living room space with a fire pit. There were stairs in the corner that descended into a sunken library, walled with bookshelves. There was no ceiling so that they could easily fly into it if they wanted, and there was a small army of squashy red couches on the floor that looked perfect for curling up in.
And it only got better from there. The main level was the surface of the mountain, with the rest of the rooms built in the same style as the library in a descending fashion. There was everything imaginable, from a dance studio to an office for Soobin and a palatial closet that was bigger than Kai’s old house.
And then there was the nest.
Kai’s mouth ran dry as he realized that the nest itself protruded off the mountain top, its massive round mattress piled high with pillows and blankets. It provided a nearly 360 view of the entire valley because of how high it was, but best of all it was built just a few feet away from a newly-constructed series of waterfall pools. Kai could imagine waking up and slipping into the cold pool every morning to watch the sunrise, or sprawling out in his mates’ laps in the hotspring as the sunset on the mountaintop around them.
“The magic is all connected to the mountain itself,” Taehyun explained. “It’ll stay secure and stable for an eternity.”
Kai took a deep breath, turning in a full circle to take in the personal, loving touches that his mates had filled the entire den with. They had picked up on all of the subtle hints he had dropped about what he wanted, and somehow turned it into a home even more spectacular than he could imagined. Now all that was left was to see if they had picked up on that other trail of hints he had been leaving.
Satisfied, he turned to face them.
“I accept.”
Kai expected to be mauled, and he was. He didn’t even need to take a breath before all four of them were plastered against him, lips and teeth marking every inch of his body. He only had a second to hope that the nest was very sturdy indeed before Taehyun’s cock was being fed past his lips at the same time Beomgyu deep-throated Kai’s own cock and it suddenly became very hard to think at all.
The four of them took turns fucking him and biting their claim into his collared throat, their hands blazing with hellfire as they made love to him. Every touch left dark, inky swirls pooling across his skin as if they were painting him with watercolors, the magic of their claim binding the five of them irrevocably together.
Much to Kai’s delight they claimed one another as well, sandwiching him between their writhing bodies while considerately always making sure he was impaled on at least one of their cocks. By the time they finally slowed down, hands trailing slowly across their spent bodies and wings as they luxuriated in one another’s touches, the jet-black ink had solidified into unique patterns that flowed from one body to the next in a seamless tapestry.
Kai stretched, enjoying the aches and pains of being thoroughly fucked as he experimentally tried to flutter his wings. The merry clinking of the diamonds and pearls startled him — he truly had thought they had disappeared like they traditionally would because he hadn’t been able to feel them weighing him down after the first round.
“Look up, angel,” Taehyun coaxed, drawing Kai back against his chest and pointing up to the mirror suspended above their nest. Kai blushed a little despite himself at the sudden, unexpected picture of the five of them in a sweaty, fucked-out heap in the nest. His eyes went straight to his wings and he shivered at the sight of them, gleaming with the diamonds and pearls his demons had spent so long sewing, one by one, into his wings. Every piercing was individual and unique but together they were beautiful, highlighting the natural contours of his wings so that they glittered in the sunlight — almost like the glass prism glittering on his mountain top.
“We caught you,” Beomgyu said proudly. His eyes were dark with triumph as he licked into Kai’s surprise-parted lips, one hand trailing down to slip two fingers into Kai’s ruined pussy. Kai moaned and spread his legs on instinct, easily going pliant as the others spread out his wings and started grooming them. They effortlessly raked their fingers through his feathers, somehow not tugging uncomfortably at the thousands of jewels littered amongst the pristine white feathers.
“You can never leave, now,” Yeonjun agreed. “Our pretty angel is all ours, forever. You’ll be a good cumslut for us, won’t you, darling? You’ll have to be, if you want to fly again, after all.”
“I- what?” Kai managed, moaning in dazed bliss as they massaged his wings. He had wanted them to claim him irrevocably, but somehow he hadn’t expected his planning to result in this. He hadn’t known something like this was even possible, but trust them to extend the limits of courting magic — magic that they shouldn’t be able to hamper at all — to turn him into their perfect angel cumslut. “Why can’t I fly?”
“Well, you’ve been a good boy for us and let us pump you full of cum, so you can fly for a little bit,” Taehyun explained condescendingly. He rubbed Kai’s swollen belly, not giving a second’s warning before he suddenly pinched one of Kai’s nipples and tugged it hard enough to have Kai’s hole clench in surprise. He gasped in embarrassment as cum practically squirted out of his hole, smearing across his ass and thighs as it dripped down his sensitive skin.
Even more ominous, though, was the way he could feel the jewels on his wings get just a fraction heavier the second the cum dripped out.
“That’s right, they’ll stay nice and light for you so long as you take our cocks like the sweet, greedy angel you are,” Beomgyu said cheerfully. “That should be easy for you, shouldn’t it? After all, there’s nothing you like more than being pumped full of demon cum.”
“You’ve been sneaky, angel,” Yeonjun continued silkily. His gaze was far too knowing as he leaned down to make eye contact with Kai. “But now, it’s our turn to call the shots.”
Epilogue
Kai sighed as he felt his wings start to grow heavier, glancing out in the direction of his nest. It wasn’t visible from his friend’s house, but that didn’t make his longing any less potent. His demons were waiting for him, and he couldn’t wait to be tucked up safe in his nest with them once more.
His wings weren’t even that heavy — as Soobin had explained after the lust-dazed haze of their mating, the gems would stay pretty light so long as he wore a plug. Not that it was ever an issue — Kai loved being fucked by his demons so much that he could barely feel the gems on his wings, although he certainly loved the way they rustled and jingled against one another.
Sometimes his demons could even be convinced to suspend him from chains connected to his wings and fuck him in midair, their wings beating strong and silent in contrast to the loud noises of his thoroughly-pierced wings. They liked to tease him that the jewels were like the tags on a dog collar, always letting them know where their angel-pet was so that they could bend him over the nearest surface and use him for their pleasure, but Kai not-so-secretly loved the garishness of the decorations.
He was the only angel in all of heaven who kept the piercings on his wings, the dense patterns of diamonds and pearls a testament to the strength of his demons’ love for him. Everyone knew him as the angel who had wrapped the Four Kings of Hell around his finger, and it afforded him a kind of awe and respect that he thrived on.
“Maybe I need to get some demons of my own,” his friend mused, glancing at Kai’s wings enviously. “What do you think, Kai? Can you teach me how?”
Kai perked up, excitement stirring as he remembered how fun it had been to lure his demons in. He was perfectly satisfied with his mates, of course, but it would certainly be enjoyable to relive the chase through one of his friends.
“Of course,” he decided. “Why don’t you find a flock you want to target, and I’ll teach you what to do next time?”
His friend laughed, seeing right through his excuse and waving him off.
“I will,” he decided. “But I’ll never be as whipped as you are for your mates. It’s barely been a few hours and you already want to go back?”
“They’re mine,” Kai said simply. And, really, that was all the explanation that was needed. He would teach his friends how to claim their own demon flocks if they wanted, and happily start a new movement modeled on his own success, but for now he had four very special demons to come home to. He had been gone for too long, and he couldn’t wait to be back with his lovers where he belonged.
