Chapter Text

Gon didn’t bother to remember his tormentors’ names, he simply referred to them in his mind as ‘Ants’ because the three of them picked on him tirelessly in tandem. 

Being one of nearly twenty orphans, most incidents he suffered from went under the radar. It probably didn’t help that the rare times he was asked where he got his bruises or scratches from, he made up excuses. The two orphanage directors had their hands full enough as it was with the younger kids. Gon was seventeen. He could grit his teeth and bear it for another year.

At least that’s what he kept telling himself but now, Gon wasn’t so sure. He genuinely couldn’t fathom why he became the target of this constant unprovoked abuse but this by far was the most extreme act of violence he’s experienced. 

It was Halloween and Gon found himself in the empty lot a block away from the orphanage with his usual group of bullies huddled in a circle around him with sneers on their faces.  

He’d been unceremoniously dragged from his bed by them minutes prior while they muffled his cries as they forced him outside. It was chilly out but only they wore warm clothing. Gon was left in his faded MHA t-shirt and black sweats, and no socks since he hated sleeping in them so now he was left shivering in the unforgiving cold. He wished he had worn some now, he should’ve known these guys would have something up their sleeve on tonight of all nights.

“He already looks like he’s gonna piss himself.” One of them snickered. 

Another one swatted the back of Gon’s head with a cackle. “Hold it, pussy. ‘Cus you’re gonna do more than that by the time we’re done.” This one was the leader, a true sicko who made it his personal mission that Gon lived in the orphanage looking over his shoulder.

Something dark and twisted was rooted deep inside this individual. A shame considering how young he was, the same age as Gon. No one should have this much evil and hatred festering in them at this age. 

“See, we found this new toy and we wanna try it on you.” The leader explained in a condescending tone as he pulled out an object from his jacket pocket and waved it at Gon.

Under the dim light coming from the surrounding lampposts, Gon squinted at the square thing in confusion. It was a black box with silver markings and weird symbols on the outside that looked Satanic. His lack of reaction seemingly angered them because one of them kicked him in the ribs, sending him to the cracked pavement.

“Boys, it’s okay.” The leader smirked before lowering himself to Gon’s level. “This here summons demons. Or so I’ve been told. It’s simple really: just need some blood from a sacrifice and recite some words here, and bam! The sucker whose blood is used is what lures the demon out. Sounds fun, yeah?”

Oh, great. Whatever lunatic filled these guys’ heads with horror fantasy lies should be ashamed of themselves. Gon knew to bite his tongue yet the building adrenaline inside of him clouded his judgment but he was tired, cold and fed up, and wanted to be back in his bed. Not dealing with these idiots. 

He sat up and met the leader’s taunting gaze. “The only demons here are you. And if you think that actually summons demons, you’re dumber than I thought. You got duped.” 

A sickening crack shot through the empty lot as Gon’s head whipped to the side. He bit his tongue from the force and tasted metallic blood instantly as pain swelled up in his face. With a soft wince, Gon spit out a glob of blood. It landed wetly on the cold ground.

“Oh? Look who’s finally grown some balls. Didn’t think you had any. Actually, I still don’t believe you do. Boys, check.”

Panic rose in Gon and he scrambled backwards to flee from the rough hands coming down on him. 

“No! Don’t touch me!” His pleas were ignored as usual. 

Three against one was a disadvantage for Gon and in seconds he felt cool air on his thighs and legs as the bullies ripped his pants off, leaving him in his boxers. Cruel laughter filled the frigid air. Gon tried curling up but kicks to his body prevented him from covering himself. He shivered as the cold pavement pressed against his skin. 

“You can barely see a dick let alone balls. You sure you’re a dude?” One of them jeered. 

Laughter continued raining down on Gon like bullets. He made several attempts at getting up but they stomped on his body every time, making him cry out. 

“Stop—“

His begging fell on deaf ears. Not that he was sure they could even hear him over their hyena cackling. It seemed like for hours he was used as a punching bag when it was only a couple of minutes before the leader called for order.

“Hold the fag down.” 

Those sharp words caused another wave of panic to surge through Gon and he was shoved to his stomach, immediately feeling weight pressing down on him uncomfortably. He tried to wiggle and buck but to no avail. The leader straddled his back while the other two kept his bruised legs and arms pinned. When Gon heard the unmistakable click of a switchblade, he realized the severity of his situation. 

He cried out when a hand yanked his head back by his hair, forcing his neck to stretch out. His blood ran cold as the icy tip of the blade lightly drew across his skin. 

“Whaddya think, boys? Artery is looking real nice here. How about the tongue? Shut him up for good. Or should I go for the wrists? We need enough blood to cover this thing or what?” 

No, please no. Gon’s voice was shriveled up in his throat. He didn’t dare to even breathe at the moment with such a posing threat near. The knife was sharp and heavy and one slice Gon knew he could bleed out in minutes.

“Remember that crazy bitch said only blood is needed, not how much.”

“I wanna see the demon kill him, ain’t gonna be fun if he’s dead.”

They’re insane. And what crazy bitch? They must’ve been sold this shit on the street. Gon squeezed his eyes shut, a little whimper slipping from his mouth. 

“Aight, gimme his hand.” And just like that, Gon was freed from the stony grip and slumping to the hard ground again. 

His relief was short lived when his hand was seized none too kindly and his palm was cut open. There was nothing finesse about it, the leader dragging his blade in deep, causing a thick string of blood to fountain from the gash in seconds. 

Gon winced at the pain while watching helplessly as his blood stained the box. There was no way, no fucking way this was happening. In his state of shock, it took Gon a few moments to realize the Ants were chanting something. It was then he remembered the leader mentioned something about reciting some words. Well, whatever the fuck they were saying wasn’t in a language Gon understood. He was convinced these guys were just batshit crazy and needed serious psychological assessments. There was no way they believed they were summoning a demon. Nothing was going to hap-

Gon froze when the box began glowing blue.

“Holy shit.” One of the bullies muttered.

Evidently, their bizarre chanting was successful.

Streaks of blue light shot from the box like crackling lightning and the next few moments catapulted into a whirlwind of chaos. Gon closed his eyes as a strong, eerie wind swept through the lot, all the lampposts in the vicinity flickering while a buzzing sound filled the air. 

Goosebumps surfaced across Gon’s skin but it wasn’t from the sudden drop in temperature. No, something unsettling invaded the atmosphere. The light vanished as quickly as it had come, leaving a foreboding heavy silence in its wake.

And then a low voice spoke up, shattering the stillness.

“Heh. What the fuck do we have here?”

A shiver ran up Gon’s spine as he opened his eyes and spotted the dark figure. 

🕸️KG🕸️

Killua has always found humans an idiotic race. They were annoying, a waste of existence, particularly the simpletons who only got off on greed and wealth and damaged the earth with their selfishness. Empty headed cunts. Humans did stupid shit on a daily basis but when it came to certain holidays such as Halloween, the stupidity skyrocketed. 

Had no bounds.

Many people were obsessed with the ‘paranormal’ aka, Killua’s realm, and while most tended to stick with horror movies and attractions like haunted houses, there was always that one group that liked to take it further. Ghost hunters were harmless and Ouija board users were incompetent but it was real special morons who like to do demon summoning rituals. 

These tactics humans use at trying to ‘summon’ them was a running joke in the demon world, especially when some humans used blood for bait. There was no bait needed when demons had the ability to travel to the human world anytime they wished and owned sharp senses that could detect anything past the filmy barrier between both worlds. 

That’s why Killua wasn’t at all surprised when he felt an artificial summoning box activate. There were several others around the world currently activated, however, the potent blood on this box had an unusual sweetness to it that swiftly caught the demon’s attention. Never in all his 2100 years had a summoning intrigued Killua. He didn’t expect to indulge in any dumb human affairs for tonight but that ambrosia blood was too delectable to ignore. 

Of course he gave whoever on the other side a grand entrance just for fun. He was going to kill them either way so might as well show off before ending their pathetic existence. 

A quick scan of his surroundings showed Killua he materialized in the middle of a vacant rundown lot. His sharp eyes counted four humans in total but immediately the demon could tell something was off. As it was a summoning, it was obvious the human on the ground was the sacrifice if his bloodied hand was of any indication. And also the fact that two of them were holding him down while the third was sitting on his back. Ganging up on one? Predictable, barbaric human behavior. 

They were teenagers which further amused Killua who not just smelled the fear radiating off the group but could also see it in their eyes. They gaped at him like they couldn’t believe he was there, as if they conveniently forgot that they were the ones who ‘summoned’ him.

“Heh. What the fuck do we have here?”

A collective shiver ran through the group but it was only the sacrifice Killua paid attention to. He was smaller than the others and considerably bruised up, and yet despite all that, Killua had never set his eyes on anyone more sweet looking. Inky black hair framed a pretty, round face with striking honey gold eyes and soft full lips that was smeared with blood looked ever so inviting. The open wound on his hand confirmed this was the saccharine blood that enticed Killua out. The demon couldn’t wait to taste but first, he had to deal with the trash. He turned his attention on the three stooges.

It appeared that they were over their shock enough to talk with each other in hushed voices but Killua’s pointed ears easily picked up on their conversation. 

“What the fuck?! Did he really come from the box?”

“L-look at his eyes. Shit, man.”

The one sitting on the sacrifice’s back got to his feet, unable to take his wide eyes off Killua. With a shaky finger, he jabbed a finger at him.

“You a demon or what?” The fucker attempted to sound intimidating but the tremble in his voice gave him away. 

Killua sneered coldly and cocked his head to the side. “Isn’t that why you shitheads summoned me?”

The three dummies gasped before sharing looks with each other. Then the alleged leader took a step towards Killua with a shit eating grin.

“So that means you gotta listen to what I say now. Do my bidding or whatever. Listen closely, demon, and kill this piece of shit.” 

He gave a swift kick to the sacrifice who yelped in pain, tucking in on himself. Killua watched impassively even when scared golden brown eyes looked up at him.

“Pl-please don’t!”

“Shut up. Don’t be scared now!” When one of the goon’s went to kick the smaller boy, Killua didn’t give him a chance to connect. 

Depending on the mood, the demon enjoyed dragging his killings out. A little torturing here and some tormenting there was a nice pick-me-up, but right now he was annoyed with these little pricks thinking they could throw demands at him. Also, he wanted nothing more than to get his mouth on that sweet little sacrifice. So in an abrupt blur, Killua slaughtered the trio.

Gon squeezed his eyes shut as if that would block out the sickening crunch that echoed in the air and the Ants’ gurgling screams that followed. The grotesque sounds of their flesh ripping and blood splattering had him turning pale. Even when silence fell once more, Gon kept his eyes sealed closed. He didn’t dare to look or move. Maybe this was all just a bad dream his paranoid anxious mind conjured up. His heart thundered loudly in his tight chest, racing faster when heavy footsteps walked towards him.

“Fucking vermin. Trying to call the shots. Hey. Are you okay?” That rumbling voice was right above Gon but he was too scared to look up. 

Killua stared down at the trembling sacrifice, taking note of the bruises and cuts on his slender body. His arms were covered in them and Killua wondered why the human wasn’t wearing warmer clothes or pants for that matter. The cold didn’t bother him but humans were fragile things, even something as mundane as the weather could be their demise. And this particular human was weak looking. Such a meager little one. 

Killua conjured up a dark blue cloak before squatting beside the boy, his swift movement invoking a flinch. He paid it no mind while draping the cloak over the quivering human. 

“I’m not going to hurt you. I see those fuckers did enough damage but they won’t be hurting you anymore.”

The sudden warmth enveloping Gon along with the comforting lull in the demon’s voice confused him. He wasn't going to hurt Gon? The teen braced himself with a soft steady breath before tentatively raising his head.

The first thing that stuck out to Gon were the pair of otherworldly eyes. They were blue with silver moonlight sclera, so piercing and vivid. They regarded Gon calmly as he cautiously inspected the demon further.

If not for his eyes and ears, the demon could’ve passed as a human. A ridiculously handsome one. Gon realized he was staring and quickly averted his gaze, becoming distracted with the lengthy thick mane of spiky silver hair coiling down the demon’s back tied together at the end with a black band. 

So long. Gon thought to himself before heat rose to his cheeks when he finally became aware of how the demon was dressed. He was wearing a black short sleeve turtleneck crop top that stopped right under his firm pecs, stretching across his broad chest and fully displaying his rippling abs while baggy white pants hung low on his hips. Black slips covered the demon’s feet and one silver earring dangled from a pointed alabaster ear. 

“Well, aren't you just a doll?” The demon drawled, a small smirk playing on his pale lips.

Gon could only stare dumbly as the demon reached out and gently wiped the corner of his bottom lip. He was surprised he didn’t jump back from the sudden contact but the touch was soft, soothing even. The demon went on to cradle Gon’s small hand in his larger clawed one, inspecting the slit in Gon’s palm. Without warning, he brought Gon’s hand to his mouth and licked a broad stripe over the wound with an abnormally long and hot tongue. 

This time Gon did startle from the sensation, hand jerking but Killua had a firm grip on him. He swirled his tongue, diligently collecting the appetizing blood from the wound, savoring the sweet taste. Gon let out a small gasp as the gash on his palm closed up until it looked like a knife had never sliced it open and the throbbing pain disappeared. His mouth fell open. 

“H-how did you-?” 

Killua smirked while letting the boy’s hand go. “I’m a demon. What’s your name? Mine is Killua.”

Gon peeled his eyes off his healed hand and shyly met Killua’s otherworldly gaze. “I’m Gon.”

“Hm. Gon. I like that. So, Gon. Something tells me you weren’t out here with those bastards by choice.”

Gon shook his head while carefully sitting up. “They dragged me here. They’re always messing with me, but it’s never gone this far before.”

“Like I said, they won’t be bothering you anymore.” 

Killua’s sinister tone reminded Gon that his bullies were in bits and pieces strewn across the lot. Oddly enough, it didn’t bother him knowing they were dead. And he was definitely lying to authorities when it came time for questioning. 

“You live nearby?” Killua asked. 

“Am, the orphanage around that way.” Gon pointed in the direction his home was. He should leave, but his body felt rooted to the ground. 

“Orphan, huh?”

Killua earned a quiet nod, Gon’s eyes focused on the cloak he was mindlessly playing with. Being an orphan meant the teen was practically free for grabs. Even if he had a family to go back to, the demon had no intentions of letting him go. Unlike the majority of humans, something about Gon was strikingly, refreshingly different. 

Killua wanted him. 

Gon was oblivious to the demon’s inner musings, too preoccupied with his worrying thoughts. It was so late now and he inwardly sighed, hoping he would make it home in one piece without running into anyone because he wouldn’t know what to do or say if he did. He bit his lip before making a soft wounded noise when his teeth dug into a cut. 

And then promptly froze when fingertips brushed across his lip. Killua tilted Gon’s chin up with two fingers and pulled him in close, eyes roving across Gon’s bruised face. It angered him that those punks put their grimy hands on this little treasure. 

“Stay still.” 

That was all the warning Gon got before a pair of lips descended on his. He let out a squeak of surprise and Killua took advantage of his parted mouth, wasting no time in surging his tongue past the pillowy seals and entering Gon’s soft wet mouth. Instantly his taste buds flooded with Gon’s nectarine blood, coating his tongue as he swiveled it around, brushing over the small cuts inside. He dribbled his saliva inside, the substance containing healing properties and lathered it across the wounded fleshy walls. 

Gon’s mind was whirling. This was his first kiss. His first kiss was with a demon. Could this even be called a kiss? He remembered watching a cheesy holiday movie one time during Christmas and the couple at the end shared a deep-filled romantic kiss. It was nothing like what he was experiencing now; he couldn’t even return the kiss Killua was dominating. He plundered Gon’s mouth, spit leaking down the corners of the teen’s lips. The press of their lips and the heat of Killua’s tongue sparked a simmering heat that spread through Gon. 

Under the haze, Gon could feel the numbing pain disappearing. When Killua licked his bottom lip, there was a slight tingle before the once stinging pain vanished. 

Killua pulled away leaving Gon gasping for breath, inhuman eyes surveying him. His plump lips were kiss-swollen but the bruises and cuts were fading, which was all the demon wanted. Of course it was a bonus to sample those sweet lips and even sweeter blood, the rich flavor letting Killua know Gon was a virgin. He wanted nothing more to bring him to his first orgasm, dick twitching at the thought but he reined in his arousal for the time being. 

“Open up.” Killua gently tapped Gon’s lips.

Gon found himself obeying with glassy eyes and Killua, who still had a hold on the teen’s chin, tilted his head back so he could glimpse inside his mouth. No cuts in sight. The blood was all licked up, absorbed into Killua’s tongue. 

The demon smirked. “Feel okay?”

“Mm.” Gon blinked, fluttering his lashes and blushing when Killua pecked him on the lips. 

“Come on.” 

Killua hauled them to their feet, making Gon stumble slightly, legs jelly from being on the ground for so long. He didn’t stand on them for long because Killua swept him off the ground into his strong arms, holding him bridal style. 

Gon’s heart thudded in his chest. He’s never been held like this. He was sure Killua could feel the rhythmic pumps of each beat. 

“Are you taking me home?” Gon asked. 

“Not banged up like this.” Killua answered while cradling Gon closer to his chest. The boy was lightweight and his body was soft all over. 

Gon didn’t know how to respond to that. All he knew was that the demon’s arms were a warm cradle and he smelled surprisingly good, like firewood smoke. 

Killua waved his hand across the empty lot, making the decapitated bodies and blood disappear, once again shocking Gon who watched it sizzle and fizz away until nothing remained.

Amused by the teen’s expression, Killua secured his grip on Gon. “Hold on tight, doll face.”

Gon only had time to wrap his arms around Killua’s neck before the world toppled beneath him in a spinning blur.

Chapter Text

Killua stepped out from the shadowy cloud of silvery-blue mist and into his candlelit lair with Gon still tucked in his arms. It was just as he left it, the room spacious and organized with inky background and deep blue accents. The size was similar to a penthouse but without the windows or towering heights. No doors either, everything was open. 

One entire side was a wall of bookshelves with a large black desk and matching chair occupied its corner. On the opposite side was a kitchen despite demons not needing to consume human food. The only thing Killua had stocked in the cabinets were a variety of chocolates, his only exception and favorite human indulgence. In addition, there was a lounge area with plush looking twin chairs and a wrap around couch. Not for guests, (gross) it was just to fill the space but recently Killua had been thinking about switching it out for gym equipment. 

Then there was his bed. While there was no bedroom door, Killua did have midnight blue sheer curtains hanging around it, giving it some semblance of privacy. His bed was massive and cloud-like with wispy grey silk sheets. An array of soft pillows lined up against the headboard and a thick, dark blue comforter draped down the sides to the plush rug floor the bed resided on. Demons didn’t need to sleep either, but Killua enjoyed his bed. 

And as he carefully placed Gon on the center of it, he knew he was going to love it even more. When he tried leaning back, he found he couldn’t get far with the human clinging to his neck with a death grip, garnering a small smirk from Killua who chuckled deeply.

“You can let go now, sweetheart.”

Gon slowly peeled his eyes open but didn’t move until he was certain that the spinning sensation had stopped. When it was clear that they were no longer moving, the teen cautiously withdrew his arms from Killua’s neck while meeting the demon’s amused eyes. Their faces were so close to each other, Gon felt his cheeks warming up.

“Sorry.”

Moon eyes glittered.

“Don’t be.”

Skating his gaze away, Gon glanced around feeling slightly curious. He realized he was on a bed— a truly sizable and comfortable bed, but that was the extent of his knowledge. Through the opening of the bed curtains, all he could see was dimness. “Where are we?”

“My home.”

Gon wasn’t expecting that. He sat upright, eyes wide. So that meant— was he in-?

“Is that, um, does that mean I’m in the demon world?”

“Yes.” Killua chuckled. He reached out and gently carded his hand through Gon’s hair. “Don’t worry, you’re safe here with me.”

Those murmured words and gentle caress comforted Gon in a way he’s never felt before. Truthfully, his short time with Killua has been nicer than how his mundane life treated him. The orphanage was stifling with so many kids and with his bullies tormenting him on a daily basis, Gon spent hiding alone as much as he could but he could never escape the never ending noise. It was loud and hectic, and lonely. 

School wasn’t remotely better.

He didn’t want to go back. There was nothing there worth for him to return to. He found himself soft and addicted to the attention Killua had given him, he didn’t want to part from it now that he’s had a sample of it. Ironic how the stuff from nightmares was making Gon feel at ease. 

“Can I stay here?” The words leave Gon before he can stop them.

But Killua merely smiled, teeth gleaming behind his pale lips. He stroked Gon’s cheek before curling a finger under the boy’s chin, tilting his face upward. “I wasn’t planning on letting you go, doll face.” Gon blushed at those words, delivered with affection that enveloped him with fluttery warmth. 

For the second time that night, Gon was kissed. Following Killua’s words, the deep kiss felt like a promise being sealed. Killua molded their lips together like it was the most natural thing in the world. Graceful, commanding, opposite of Gon’s clumsy lips that pressed back shyly. 

In one swift motion, Gon found himself on his back with Killua caging him down, settling between his legs so naturally. 

As his breath was sucked from his lungs, Gon shivered slightly when long fingers peeled up his shirt and hands cupped his sides. Slight pressure reminded him of the merciless kicks he received before the soreness and dull ache disappeared entirely, replaced with a bubbling warmth that soothed his ribs and skin. 

He gasped softly into Killua’s mouth and the demon took the opportunity to slide his tongue inside, sweeping it around with languid strokes, tasting how sweet Gon was. Like cinnamon dusted peaches. 

Killua’s touches grew heavier once he rid Gon of his shirt, leaving him only in his underwear. He mapped out the teen’s body, squeezed handfuls of soft, malleable skin, favoring the extra layer around Gon’s thighs before closing his hands around that slender waist. Gon was so tiny, Killua’s fingers brushed together. 

Gon quivered from the onslaught of new sensations, finding himself enjoying Killua’s hands on him all while the demon branded searing kisses into his sensitive skin. From his throat and the patch of velvety skin behind his ear, to the curve of his jaw and neck, Killua left his mark. It rendered Gon breathless and heated. The lips sucking on his neck merely heightened his pleasure and he didn’t realize he was hard until Killua grinded down, pressing their erections together. 

“Ah~!”  The embarrassing moan escaped Gon before he could stop it. His hands flew to his mouth as Killua paused and looked up, gaze twinkling.

“Cute.” The demon cooed. 

Flustered, Gon covered his face with a quiet whine. 

Killua chuckled and placed a kiss on the back of Gon’s hands before trailing his lips southward. He eagerly acquainted himself with perky brown nipples, sucking the nubs until they glistened from his saliva. He relished in the darling sounds Gon released and ventured further down, smothering Gon’s flat stomach with nips and kisses. How easily he became addicted to the petal soft skin. Hickeys bloomed prettily across the caramelized surface, replacing the bruises. Killua sunk his teeth into the fleshy dip between Gon’s hip and waist while his large hands gripped his ass. 

“Baby, baby. Such a pretty thing you are,” Killua purred as he nosed along Gon’s inner thigh, “gonna make you all mine.” 

Gon couldn’t look away from those starving moon-blue eyes that were in slits staring up at him. He felt pinned under their weight, helpless yet safe. 

He held his breath as fingers peeled his underwear to the side and Killua ducked his head down without breaking eye contact, sticking out his tongue. The instant warmth at Gon’s hole was electrifying, making him gasp loudly. 

“Like that?” Gon couldn’t see Killua’s lower half of his face but from the glint in his eyes, the demon was definitely smirking. 

Without waiting for an answer, the hands on Gon’s ass spread his cheeks apart and with a playful wink, Killua ducked back down, face fully disappearing. 

And oh-

“Ngh!” 

Wet and curling, the heavy drag of Killua’s tongue forging a path inside Gon was sinful. The first lick had been swift and teasing, just an innocent swipe over his rim but now Killua was driving it through with purpose. Each deliberate stroke heated Gon’s sensitive body, dripping kerosene and lighting him up from the inside. 

Killua pressed in deeper, face all but squished against Gon’s ass as he fucked the teen open with shoving thrusts. He ripped, literally, Gon’s underwear all the way off, flinging the shredded fabric free from his claws, unable to get enough of the sweet taste or how those soft inner walls clamped down on his tongue. It was hot and wet, and tight. 

Every jab caused the prettiest whine to fall from Gon’s lips and his thighs to tremble, and Killua found it oh so precious. Especially the way Gon was rolling his hips down to meet his mouth, cute thing didn’t realize he was even doing it. One glance up showed him that Gon was gripping the bed sheets with his small hands, face to the side and biting his bottom lip. His slender chest was flushed and heaving slightly, nipples slightly puffy and still glistening from Killua’s saliva. His neglected dick was hard and dribbling, curled upward towards his stomach. A ruddy tint that was so fucking pretty. 

Killua angled his head for a deeper reach and in turn got his head pleasantly locked between squeezing thighs. He let out a low guttural hum while continuing his ministrations, tongue nearly a blur from how rapidly he was flicking it in and out Gon’s soaked hole. He nipped at the rim before giving it a few teasing sucks and then resumed thrusting. He reached up to wrap his hand around Gon’s dick, thumb sliding over the slit and spreading around the pearly drops of precum. 

Gon was absolutely falling apart. And Killua didn’t let up. Not until he claimed Gon’s first orgasm, a beautiful sight to behold. He filled Killua’s hand with his warm, ripe seed while Killua sucked furiously on his puffy hole, two fingers (sharpened claws receded) shoved in alongside his tongue. 

By the time Gon calmed down from his climax he was blushing all over, pink coloring his round cheeks and staining his neck. Killua watched in amusement as the color deepened when he moved back to take off his own clothes and finally revealed his own throbbing dick. 

Gon’s kiss-swollen lips fell open slightly at the sight of it, his heart pounding in his chest. He wanted to speak but words failed him. Even if he weren’t a virgin, Killua’s size was intimidating.

“Keep ‘em spread, babydoll.”

Fingers tapped his legs which Gon didn’t realize he had closed. He parted them and Killua wasted no time in shuffling forward to fill the shyly offered space, all while lazily stroking himself. 

“I’ve never done this.” Gon whispered feebly. 

“I know.” Killua leaned down and kissed his forehead. “I won’t hurt you, sweetheart. I’ll make you feel good. Give it to you ‘til you won’t want me to stop. But I will stop if you want, at any time. I’m not some jackass demon.”

That both warmed and settled Gon, and the nerves swirling inside him faded away leaving only anticipation. Killua looked pleased as if he knew he had calmed Gon down and kissed those sweet addicting lips. 

“Okay?” Killua rubbed their noses together, mystical eyes boring into Gon’s. 

Gon nodded with a small smile. “Okay.”

Fuck, how was one human so beautiful? Killua spat in his hand, using his saliva to lube his thick length up before guiding it to Gon’s slicked hole. He paused to lift Gon’s legs around his waist and placed a soft kiss on the teen’s cheek.

“Relax, baby, and hold onto me.”

Gon did as he was told and slid his arms around Killua’s broad shoulders, bracing himself with a breath when he felt something hard and hot pressing against his entrance. Killua set his arms on either side of Gon’s head bringing them chest to chest, face to face. 

The push in sent an aphrodisiac rush through both of them. Despite Killua’s size, the stretch wasn’t as intense as Gon had expected. The burn was present, yes, but the pleasure overriding it traversed up Gon’s spine and down to his toes, consuming him whole. Killua locked his jaw as he slowly filled Gon, sinking into slicked softness, his length completely compacted by a wall of tight feverish heat. 

By the time Killua buried himself to the hilt, he was barely holding back from pounding into the sweet tightness cinched around him. He couldn’t stop from grinding minuscule circles against Gon, heavy balls squishing against the teen’s ass. 

Gon made a tiny sound at that, hands gripping tighter on Killua’s back. He’s never felt so full in his life. Killua was wedged deep inside, thick and hot, taking up every bit of space, making Gon see stars. He jerked slightly with a cry when in the midst of Killua’s grinding, the tip of his dick grazed something that had Gon’s vision flashing. He arched up, trembling legs closing tighter around Killua and pouty lips hanging open. 

“Let me know when I can move.” Killua pressed gentle kisses across Gon’s face and neck, a contrast to how he felt which was wanting to fold Gon over in half and fuck him until he was choking on sobs. 

“Y-you can.” Gon met Killua’s ivory-blue eyes, looking all demure and lovely. Sweet voice shy but sure with granting him permission. 

The demon had never been overpowered so easily. 

He fused their lips together while pulling his hips back, the delightful pressure of Gon’s walls squeezing him until just the tip was in. Then he sheathed himself back inside with a steady thrust, filling Gon back up in an instant. 

The breath was knocked out from Gon’s lungs but he didn’t have time to catch it because Killua picked up tempo, fucking into him relentlessly. Feeling the heavy drag of Killua’s dick carving through him deeply was surreal. He keened helplessly into the devouring kiss, feeling lightheaded and overstimulated. Fwopfwopfwop. The sound of their skin clapping together echoed loudly and all Gon could do was cling to Killua as he was railed into the sheets, animalistic thrusts jerking his body. 

Killua kept one hand next to Gon’s head and slipped the other down to grab a handful of his jiggling ass, hitching him even closer to meet his thrusts. He pressed a kiss to Gon’s ear before moaning into it, deep and guttural. 

“Ngh, you feel so good. Fuck.”

Gon let out a watery hiccup that trailed into a high pitched wail when Killua repositioned them again, lifting Gon’s leg in the air, strong hands keeping the quivering limb in place while straddling the one on the bed and surging his hips forward, somehow going even deeper at the new angle. Moments later, Gon went slack-jaw as he orgasmed for the second time that night. Pearly drops of his essence landed on his thighs and stomach, his hole clamping hard around Killua whose hips twitched in response.

“That’s right, sweetheart.” Killua cooed encouragingly at him, pressing comforting kisses to his ankle but didn’t stop fucking him. Gon babbled and writhed, trembling like a newborn fawn from sensitivity.

No matter how far his dick dug deep, being engulfed by the softest warmth, Killua couldn’t get enough. An insatiable appetite unraveled in the pit of his stomach, greedy and voracious, wanting, needing more and more. In a trance, he gazed at their lower bodies colliding with the messiest squelches. Watched how his dick, stringy with their mixed precum, opened Gon up and entered his body, the way the outline of his length appeared under the teen’s creamy skin beneath his bellybutton. Gon’s rim stretching around him was as mesmerizing as his round ass rippling and clapping. 

Tears streamed rapidly down Gon’s face, another outlet for the overwhelming pleasure overflowing him. He was buzzing, his mind swimming, only registering the way Killua filled him, bludgeoning his sweet spot again and again. His third orgasm ripped through him when he was on his stomach with Killua delivering ruthless back shots from behind. 

Gurgling sobs and thunderous claps bounced off the walls as Gon was fucked into the mattress. Pale hands had a death grip on his waist keeping him pressed down from chest to head while his back was arched, flushed ass in the air meeting Killua’s thrusts. If not for the grip on him, Gon would’ve long since collapsed against the sheets. There was no more strength left in his body which felt like jelly. All he could do was garble into the pillow his wet face was squished against and take Killua’s dick. 

“Baby, you’re doing so well for me.” Killua praised in a low tone.

He lowered himself down, plastering his chest to Gon’s damp back while slipping his hands into his. Immediately Gon squeezed his fingers, clutching them like a lifeline. Cute. Killua nosed at Gon’s cheeks until the boy lifted his face. His mouth was already open so Killua had no problem surging in and capturing those pillowy lips. Soft ‘ahahah’s panted against his mouth as he began fucking Gon earnestly, chasing the orgasm he’d been holding off purposely. Now he was on a mission to see his pretty little doll dripping with his cum. Then he’d fuck it all back into him.

Gon didn’t think he had any cum left in him but the way Killua’s weight pressing heavily down on him aided in his untouched dick rubbing against the sheets, on top of Killua pounding him incessantly, he managed one last climax. It was weak, just a few spurts releasing from his spent length but still enough for his vision to blur and body convulse. He broke away from the messy kiss with a strangled cry and seconds later, passed out.

Gon’s swollen hole tightened so excruciatingly, Killua worried about his dick snapping off for a brief moment. The heat suctioned around him finally sent him over the edge and he spilled into Gon with a shuddering moan, cum gushing in rapids until Gon was leaking. Killua didn’t need to look to see that when he felt the hot liquid seeping between their bodies. He gave a few lazy shallow thrusts, dick sloshing through a wall of slick, before moving them to their sides in a more comfortable position. 

With Gon slumbering in his arms, Killua finally settled and plugged him up, his dick completely sealed by the teen’s tight ass. He pressed soft kisses to the back of Gon’s neck and shoulders, murmuring sweet nothings despite there being no answer. He knew he would have to wash up his sweetheart eventually; make changes to his lair as well so Gon would be comfortable and have all the necessities he’d need, but for now all he wanted was to keep holding him.
