"Killua, I'm in love with you."
Killua's entire world… it just froze.
Those words, they were everything he'd been dying to hear since… forever. Not since he'd first started to feel these incredible things. Not since he'd figured out what these feelings meant. Not even since he'd first accepted this burning need inside him for Gon. No, not at all.
Killua had needed to hear those words from the moment he'd met Gon.
From the moment he'd laid eyes on this incredible god of a person.
Hearing those words fall from Gon's lips, it was like each and every star suddenly aligned. It was as if everything was finally right. It was as if everything finally made sense.
Killua's heart was a thundering racehorse, galloping in his chest. His heart swelled to the point that he was surprised it didn't just burst right then and there, killing him as he went down in a final blaze of glorious joy. Spectacular warmth and that incredible sense of belonging cause Gon loved him back.
The tears burst forth, slipping down his cheeks and spilling forward in a waterfall of unparalleled joy, unconditional love.
He was frozen. He couldn't speak. He couldn't move. He couldn't even blink.
Gon stood before him, eyebrows drawn together, amber eyes wavering with that anxiety, that anxiety that Killua understood, that he identified with–
Killua knew, he knew exactly what Gon was thinking and exactly what he was feeling, and it was insane because Gon returned these feelings that he'd been harboring for so long and even though he'd suspected their return for months now hearing it out loud was just an entirely different story and–
Killua found himself grinning.
Grinning through his tears, the brightest and widest smile he'd ever graced upon the world in all his nineteen years of life.
Gon's cheeks flushed, Killua could hear the other boy's heart racing in his chest. He watched Gon's gaze dart back and forth between his eyes, unsure. So incredibly nervous. A bundle of anxiety and nervous energy.
Gon's fingers trembled in their hold on Killua's shoulders, he was so scared.
But he'd done it. He'd taken that leap of faith, taken that step that Killua himself was far too unsure and nowhere near brave enough to take.
And Killua… Killua didn't think it was possible, but he suddenly loved Gon a thousand times more.
Giggles wracking his shoulders, Killua leaned forward, resting his forehead against Gon's. "You idiot," he breathed, "Why didn't you say it sooner?"
Those amber eyes blew wide, wider than before. Tears pricked in the corners, Gon's mouth cracked open, the hope splattered across his features, the joy…
Killua couldn't get enough. He wanted to make Gon feel happy like this for all eternity. He never wanted to see Gon sad or angry ever again. He wanted to wipe every wrinkle from that brow, he wanted to thread his hands through that black-green hair and extract each and every negative emotion that every dared raise its unwanted head in Gon's psyche.
Because Gon deserved the entire world.
And Killua would sacrifice anything just to see that he was eternally happy… eternally free.
"I love you too," Killua choked out, throat thick with happy sobs.
He couldn't see straight through his tears, the entire world around him had just vanished, there was nothing but him and Gon. Him and Gon, surrounded by a sparkling universe of light and hope and everything that was good.
Gon's face fell slack with shock, sparkling silver tears slipping down his cheeks and dripping off the tip of his chin. He completely froze up, just like Killua had… he really felt everything, he seriously felt everything that Killua did.
His every emotion, his every sentiment. They were all returned, they were all mirrored in Gon's beautiful amber eyes.
Gon took a deep and shuddering breath, his fingers squeezed tight around Killua's shoulders. He leaned back, staring frantically and almost desperately up at Killua.
"Really?" he asked, voice cracking on the word. He sounded so disbelieving… like he couldn't possibly fathom that this was actually happening. That this was actually real. Killua, he felt the exact same way.
But it was real. This was happening.
And Killua knew that it was because there was no way to fake the way Gon's eyes glimmered in the light… the texture of his skin and the shadows that played across his features during the night cycle… the sparkle of his tears and that subtle hint of salt… the pounding of his heartbeat, and the way his fingertips dub into Killua's shoulders.
"Yeah," Killua confirmed, nodding as the tears just kept tumbling down.
Gon whined, his face contorting into a sob. His lips wobbled, his eyes sparkling and tear stained. He was messy, he was an emotional wreck, but all the same. He was beautiful. He was Gon. He was Killua's light and love, the center of his entire universe.
"Killua–" Gon gasped, eyes wide and face alight with wonder.
He tugged the assassin forward, and just like that, kissed Killua's lips. Gon's mouth brushed against his in just the ghost of a touch. It was sloppy, uncoordinated, and Gon's lips were wet from his tears and tasted of salt. But even so, Killua's heart lurched. This moment had been everything he had been waiting for. Everything he'd strived for in the dead of night, watching Gon from behind in the heat of the day.
Killua was so shocked that he could do nothing but stand there and gape.
Gon pulled back, just as drawn aback as Killua was.
The two of them just… stood there for a moment. Frozen up, disbelieving that that had really just happened. Faces burning red, tears still slipping forth. Yes, Gon loved Killua. He returned his feelings, and there was no more holding back. No more pausing, no more burying all of this sentiment beneath layers of friendship and platonic touch.
They realized it at the same time: that barrier was down. Now, they could finally come together, not as friends, but as so much more. They could finally express everything they'd been feeling for so long. They could finally act, no more holding back.
The mood snapped tight as a wire.
It changed, and just like that…
Everything was bathed in a wild and all consuming fire.
Gon took Killua's face in his hands, and crushed their lips together. The kiss was steady and full this time, and Killua returned it with everything he had. The hybrid pulled back again, Killua's head braced in his hands. He stared at the Valkyrie's mouth like it held all the answers to the universe.
Killua's heart was in his throat. Gon had just kissed him. He'd just kissed Gon.
Again.
Killua plunged his hands into Gon's hair, pulling them back together. Killua kissed Gon's parted lips, and the shorter male kissed him back because this was real and not just some incredible dream.
If they'd fit together as partners in battle then they fit together like this so much better. Killua dug his fingers into Gon's scalp, pulling at his hair and forcing him to tilt his head to the side. Killua was drowning, he was drowning in the sensation of Gon's mouth against his and the scent of his skin. He was tumbling down and down and down, but he needed to go deeper.
He needed Gon closer, he needed to experience him in full, taste him against his tongue and crush him against his body so Killua could no longer tell where one ended and the other began. Killua's entire body was on fire, and he needed Gon closer or else he'd snuff out entirely.
Killua cracked his lips open, and slid his tongue across the crease of Gon's mouth. The shorter male responded instantaneously, letting Killua inside and taking a gasp of air. Never pausing, never letting up.
Their teeth clacked together as the both of them ran completely wild, losing themselves in the warmth before them as they scrambled for purchase. Killua wound his tail tightly around Gon's waist; it thrashed and wagged, demanding attention, demanding to be closer together.
Killua's tongue slicked up against Gon's as he swallowed the other male down. All he could taste was Gon, but he could still be closer, he could still reach further. Killua forced his tongue into the back of Gon's throat, skin prickling as the fire within him demanded that he get closer. He wanted to crawl inside Gon's body, it wouldn't be enough until they were a single being, a single soul in a single vessel.
Gon groaned into his mouth as Killua all but suffocated him with his fervent kiss. The hybrid moved his hands from Killua's hair, latching onto the Valkyrie's waist and manhandling him against the railing. Gon pinned him against the metal bars, boxing Killua in and pushing forward, stealing the dominant position right out from under his feet.
Their bodies pressed flush together as Gon pushed closer. His tongue slid into Killua's mouth, slick and tasting of musk and sweat and the remnants of what he'd eaten that morning. Gon's tongue smooshed against Killua's, and the Valkyrie could hardly remember to breathe because Gon was so good at kissing–
Killua whimpered into his lover's mouth, looping his arms around Gon's shoulders and falling slack. He was bending over backwards, Gon pushing his head back over the railing. The hybrid held Killua in his arms, keeping him braced between the heat of his body and the metal bars, not letting him tumble backwards into the depths of the city surrounding them.
Killua gasped against Gon's mouth, sucking down air in between kisses as his mind slipped further and further away from him. His head was spinning, he was falling so fast he couldn't tell where he was anymore. Saliva dripped down his neck and tears gathered in the corners of his eyes, please, don't stop–
Gon adjusted his footing, sliding his hips across Killua's as he shoved his knee between the assassin's legs. Killua gasped, both of them freezing on the spot. Gon broke the kiss, leaning back just enough to meet Killua's gaze, a string of saliva connecting their lips together as spittle dribbled down the front Killua's shirt.
They had stopped because they could feel it.
Killua's heart was racing in his chest, his entire body a pit of moment lava.
His entire being was fixated on Gon, who's hardened length was now stabbing into Killua's thigh. Gon had frozen, because he could feel Killua too.
Killua panted, eyes wide and glowing dark with desire.
"The bedroom," the Valkyrie breathed. "Now."
It was like suddenly pressing "play," Gon was on him like he'd never stopped. He crushed their mouths back together, lips wet and swollen. Killua locked his arms around Gon's neck, and Gon grabbed Killua's legs, wrapping them around his waist and hoisting Killua up.
Gon was at the sliding door in a flash, holding Killua flush against his chest and fumbling with the doorknob, refusing to break the kiss. The two of them slipped back into the apartment, Killua clumsily shutting the door behind them as Gon stumbled for the closest bedroom. The hybrid sprinted down the hallway, busting down the door and then slamming it behind them with his foot.
The room was dark and untouched, the bed fresh with the covers still drawn up.
It wouldn't stay that way for much longer.
Gon lurched to the bed, jumping up and tackling Killua onto the sheets. Killua groaned when Gon's weight embraced him in full, their cocks sliding together through the fabric of their pants as Gon ground down on top of him.
Killua couldn't keep it down, he moaned. Loud, drawn out and muffled by Gon's mouth still latched to his own. Gon responded with a growl, digging his fingers into Killua's thighs as he locked the Valkyrie's legs tighter around his waist.
The assassin clawed his fingers through Gon's hair, tugging at his scalp and straining against his weight. Gon pressed himself closer, knees digging into the quilt as he crawled forward, pushing Killua into the mountain pillows and struggling to press himself closer, as if that were even possible.
Killua was buried in throw pillows and heat of Gon's body, gasping against the other male's mouth as he drowned in friction and that spectacular heat. His entire lower half was nothing but a flaming inferno of sparks and sensation, Gon rocked his hips again and again, his hands pulling at Killua's thighs in a struggle to keep him close.
The assassin whined into Gon's mouth, eyebrows drawing together as he arched his back, struggling to get closer. He could feel nothing but the hybrid's body, he was so close–
But at the same time so far.
There was too much fabric, they were glued together but there were so many layers of clothing keeping Gon locked up and out of his reach. Killua needed to feel that tan skin, he needed to experience that scalding heat full on with no barriers standing between them.
With a decisive growl, Killua forced himself up. He shoved Gon back, flipping their positions and pinning the hybrid against the sheets. He pried Gon's hands away from his hips, and pinned his wrists to the bed to keep him still. Killua braced his knees on either side of Gon's thighs, hovering over him and leaving a gaping hole of empty space between them. Gon tried to resist, he tried to pull them back together and crawl back on top, but Killua held him fast against the bed with his tail.
The Valkyrie broke the kiss, leaning back to catch his breath. Finally able to see through the cloud of heat and scalding touch, Gon fell slack against the sheets. Done trying to fight his way back up, he lay beneath Killua, chest pumping as he sucked down air.
Killua hovered over him in the dark, his mind finally starting to catch up with everything that had just happened. Gon's glowing orange eyes cut through the dark, wide and dilated, still staring up at Killua like he was some divine creature that couldn't possibly be real.
Something about seeing Gon flushed and splayed beneath him like that stirred something in the depths of Killua's mind. A growl forced its way up his throat, a low and edgy sound that he'd never heard himself make before. His tail thrashed and swayed behind him, finally free to do as it pleased without being slapped or scolded into submission.
Killua loved Gon, and Gon loved him back.
Now Killua's body was screaming at him to lay claim to what was his.
Killua was glazed over with desire, his dick hard and straining painfully against the rubbery material of the tattered suit. He sat himself down on Gon's waist, making the shorter male gasp and shudder.
The Valkyrie grabbed the hem of Gon's shirt, tugging it and that stupid green jacket up and over his head. Killua chucked them across the room, heat crawling to his cheeks once he finally had Gon shirtless before him.
"Killua–" Gon gasped, the Valkyrie interrupting him with a wet and sloppy kiss. The hybrid groaned into Killua's mouth as the assassin ground his ass against the tent in his pants. His arms strained against Killua's grip, those hands back to pinning Gon's wrists against the sheets.
Killua took Gon's bottom lip between his teeth, puncturing the soft flesh with his fangs and drawing little droplets of blood. The hybrid whimpered, squirming as Killua slowly slid back and forth over his hips. The assassin released Gon's wrists, flashing his aura when the hybrid attempted to exploit his newfound freedom.
Killua growled at Gon until he laid his arms back down, then smiled against his lips and rewarded his obedience with a kiss. Gon panted beneath him, clearly at war with himself to keep still. Killua slid his hands across Gon's shoulders, fingers slipping against the sweat slicked skin.
He ducked down, dragging a fang along the edge of Gon's ear. "Do you know how long I've been waiting on you?" he asked with a throaty laugh. Killua licked the shell of his ear, making Gon squirm and gasp. "I asked you a question," he prompted again, running his palms down Gon's sculpted chest as he scraped his fang against the tip of his ear, drawing more blood.
"Uh– while?" Gon choked out, whimpering when Killua slid his hips forward, ripping away that friction and leaving him cold and begging.
Killua chuckled darkly, running his lips down the side of Gon's neck and sucking down that irresistible scent of his skin. "You could say that," he murmured against tan flesh, gently licking the skin before taking it between his teeth and threatening to bite down.
The assassin suckled and abused the skin on the side of Gon's neck. The hybrid whimpered beneath him, begging Killua to slide his hips back down and grant him that stimulation he chased. Killua refused, staying in his seat on Gon's lower belly.
Killua explored that tan chest and torso with his hands as he licked across Gon's neck and collar bones. He felt across the planes of his chest, running his fingertips along the crests and dips of his sculpted stomach. Killua kissed his way up Gon's neck, before finally recapturing his mouth and sliding his ass backwards, painfully slow. He dragged a low and exaggerated groan from Gon's lips, and swallowed it down as he threaded their fingers together over the hybrid's head.
"Gon," he mumbled against his lover's mouth, "I love you."
The hybrid groaned again, "Killua, I love you too."
Killua arched his back, sliding downwards as he slotted their bodies back together. He finally freed Gon's hands, slipping his slender fingers into that messy black-green hair. The assassin bucked his hips forward, making Gon gasp and whine. "You… drive me crazy," Killua ground out. "You just… danced around it, for… so… long."
"I know," Gon forced through gritted teeth, "I'm an… idiot."
"I wanna make you… crazy like I am," Killua panted as Gon spread his knees, wrapping his legs around the Valkyrie's waist.
Gon's hands tangled in Killua's silvery hair, leaning forward and tucking his chin around Killua's shoulder as he shuddered. "I already am," he growled, "Killua, you… kill me every day."
"You mean that? You waited so long I don't think you're serious~" The Valkyrie punctuated with a heavy roll of his hips, making Gon cry out.
"Yes!" he gasped, pulling Killua's hair so hard that it hurt. "Yes, I've never been more serious about anything! I just… ha, I, was stupid, and scared–" Gon cut off, jerking his hands out of Killua's hair and fumbling with the hem of his shirt. "Can I?"
Killua leaned back, nodding. Gon sat up, Killua kneeling between his knees. The hybrid reached around to the back of the shirt, and pulled it off. He flung it into the floor, Killua's hair fluffing up with static.
The Valkyrie's tail waved and flopped about behind him, the barb pulling threads in the quilts and tearing holes in the pillow cases. With trembling hands, Gon rested his palms upon Killua's shoulders. Their hearts pounded, loud enough for the other to hear. Killua's cock throbbed in its rubbery cage, his face flushed with lips parted and panting.
But even in the heat of it all, Gon's eyes were soft, glowing with earnest emotion. Unyielding love and caring. He ignored Killua's bare chest, instead leaning forward and placing a soft kiss to the center of his forehead. Killua would have asked him what the hell he was doing, but he hushed up when those hands trailed up to cup the back of his neck, and then down across his chest and stomach.
Gon's touch was feather light, and he rested their foreheads together as he gently traced the winding paths of Killua's tattoos. The Valkyrie's skin shivered when rough fingertips brushed across the skin of his lower belly, and he gave a shuddering sigh when Gon looped his arms around Killua's chest to wrap him up in an achingly sweet embrace.
The Valkyrie's breath hitched in his throat, he could smell Gon's arousal! It was so thick in the air that it was making his aura respond! How the hell was he being so calm?!
"Killua, I'm really sorry," Gon mumbled, breath rustling the curly wisps on the back of the assassin's neck.
"What for?" Killua asked, voice strained and shaky. Slowing down all of a sudden was so difficult–
"For not telling you sooner," Gon murmured, tracing little circles in between Killua's shoulder blades with his finger. "I made you wait on me. I should have stopped to listen to your heart. I shouldn't have let fear deter me from opening up to you."
Killua sighed, locking his arms around Gon's shoulders. He was so incredibly sweet… "It's alright," the Valkyrie said. "It took forever, but we're here now, right?" He leaned back, taking Gon's face in his hands and slotting their lips together.
Gods… he'd never get over the fact that he was able to kiss Gon now…
The kiss was soft, slow and caring. Gon hummed into Killua's mouth as their tongues slid lazily together. He rubbed his hands up and down Killua's back, tracing the tattoos there and sending shivers down the Valkyrie's spine.
Gon leaned forward, gently laying Killua back down against the mountain of pillows. His lips slipped from Killua's mouth to his jaw, leaving a trail of gentle kisses down his neck, across his shoulders, and down the crease in the center of his pectoral muscles.
Killua sighed as that warm tongue licked lazily against his stomach and torso, his tail twisting into itself as his face flushed from all the gentle attention. Gon was so slow, methodical and incredibly loving. It made Killua's insides completely melt. He didn't care about pleasure or sex, not really. He just cared about Killua, and making him feel like the only person that mattered, the only person in the entire world.
The Valkyrie whined as Gon slid down lower, brushing a painfully light trail of kisses just above the waistband of his ripped up suit. His breath was hot and damp, his mouth was so close to where Killua wanted it to be, but Gon was moving so damn slow.
Killua gasped as Gon's thumbs finally brushed beneath the torn edge of the rubbery fabric. The Valkyrie fisted his hands in the sheets, his core trembling as he struggled to stay still. Take it off. Come on, just take it off–
Gon sat back up, breathing heavily as he hovered over Killua. His eyes were dark, his face was flushed and he was visibly straining against his pants. But still, he'd stopped again.
"Killua, are you sure?" he asked, fingers hovering over the band of the Valkyrie's pants.
"Yes, damn it!" the Valkyrie gasped. "I'm so hard I can't fucking think straight, Gon please–"
Gon's lips captured Killua's again, hushing his scrambled words and drowning him in kisses and love. Killua moaned as he finally peeled the tattered remains of the suit off, his cock springing free as Gon chucked the rubbery mess into the floor with an echoing slap.
The kiss picked up speed again, heat sparking like mad between them. Killua sat up against Gon's lips, and grabbed his belt buckle in his hands. The Valkyrie unbuckled Gon's pants, and the hybrid helped him slip them down and kicked them off the edge of the bed.
Killua gasped and moaned as Gon's bare body slid back into contact with his own. His skin was hot and dripping with sweat, his rough fingers fire against Killua's ribs and arms. The assassin cried out as Gon slid their cocks together just right, he drug his nails down Gon's back and squeezed his knees around his hips to recreate that angle.
Gods, he'd never gone this far before, not even in his dreams–
This was completely uncharted territory, and his mind was aware of nothing but Gon's body and the rising pleasure between his legs. The hybrid buried his face into the pillow beside Killua's head, tangling one hand in that silvery mane and reaching the other down in between their legs.
Gon grabbed both of their lengths in his hand, and Killua crumbled into a molten mess as he slid his fist up and down. The Valkyrie gasped, claws digging into the pillows as they extended instinctively, tearing the fabric and sending down and feathers floating up and around them in a cloud of fluffy snow.
"Killua," Gon groaned, burying his face in the crook of the Valkyrie's neck as he sent them hurtling closer and closer to the edge by his hand.
The assassin could only whine incoherently in response, eyes squeezed tight as Gon worked his dick like modeling clay. Killua had never thought that someone's hand could feel so good a day in his life, but here he lay, coming apart at the seams.
Electricity spiked in his groin. The heat was growing, shooting straight up for the stars themselves, and threatening to crash back down to earth in a shower of a million tiny sparks. Killua's hips bucked involuntarily into Gon's palm, it felt like there was a rubber band in his lower belly and it was about to snap–
Gon just had to keep going and not stop–
The Valkyrie moaned through gritted teeth, his hips tensing up as he crashed directly into the sun. Gon growled against his shoulder as they came in unison, milky crap painting their stomachs and drenching Gon's hand.
Killua gasped as he collapsed onto his back, Gon crashing down on top of him. They lay there catching their breath, a sticky mess between them but neither could have cared less. As the shock of it all faded to little embers in the pits of his belly, Killua found himself starting to laugh.
It was slow at first, nothing more than a breathless chuckle. But it rose, picking up speed until he was giggling uncontrollably. Tears pricked in the corner of his eyes, and Killua's laughter echoed against the thin walls of the bedroom.
Gon shook himself, scrambling to his knees as he tried to figure out if Killua had broken or something–
"Killua?" he squeaked, still short of breath. He seemed unsure what to do with his hands, one soaked in cum and the other sticky with Killua's sweat and shed hair.
The Valkyrie sobbed through his laughter, a blinding grin overtaking his face. "I'm sorry, I'm just– I'm so happy right now."
Gon blinked, face flushing as his mind caught up with him. Then he sputtered, and dissolved into tears right alongside Killua. He flopped onto the sheets beside the Valkyrie, the two of them in hysterics with the occasional tear slipping down their cheeks.
The hybrid regained his composure first, rolling onto his side and leaning over Killua to cup his cheek in his palm. Killua giggled like a schoolgirl as Gon kissed his grinning mouth, eyebrows drawn up in the most adorable expression he had ever seen.
"Killua," Gon declared, smiling brighter than every star in the sky, "I love you. A whole lot!"
The Valkyrie sighed as he finally calmed down, his stomach aching from laughter and his groin still tingling and oversensitive. He slipped his hands into Gon's hair and pulled him back down, kissing him once. Twice. Three times–
But then they were just laughing all over again.
"Thank you," Killua breathed, rubbing his thumbs across Gon's cheekbones as the hybrid laid lazily over him. "Thank you for being… being you."
Gon ducked his chin, a happy tear dripping from the tip of his nose to fall onto Killua's cheek. "Yeah, thank you too," he said, voice wobbly with emotion. For once it was Gon who was too embarrassed to look Killua in the eye… he hid his eyes beneath messy waves of hair, lips turned up at the corners, face still split open in that winning grin.
Killua's heart swelled. He loved Gon so much.
Wait–
Now he could say it out loud–
"I love you so much," he told Gon. Just because he could.
Gon giggled, resting their foreheads together once again, palms cupping Killua's face as he kissed the tip of his nose. "Me too," he said before passing out from exhaustion and sheer ecstasy. "Me too."
