Sonuckles: The Curse


“What a lovely day for a run!” thought Sonic, blazing by the shore of Emerald Hill at hypersonic speed, raising a column of sand as he ran till he stopped, stretching and breathing in the sea breeze. Though he couldn’t swim and was afraid of water, he had to admit that the beach had its charm. Besides, it was nice to just lay on the warm sand and take naps while catching some rays, cradled by the sound of the waves gently crashing on the shore. He placed his hands on his hips and was about to do just that, when his eyes catched something in the horizon. He narrowed his eyelids and shielded his eyes with his hands, spotting the frame of Angel Island far at sea. 
“Heh, cool, I can see Knux’s home from here.” he chuckled, but then he gasped slightly: the island wasn’t flying. It instead floated on the ocean.
“Oh crap!” he said as he dashed for it, running on water as he went to check on Knuckles and the island, thinking that maybe the Master Emerald got stolen… again. As he thought about it, he reminisced about how long it had been til their last adventure together. Knuckles was a great guy to have around while journeying to fight Eggman and an even better friend, if it wasn’t for his grumpy behavior and tendency to prefer solitude over company. Sonic had no idea why Knuckles, after 16 years spent in solitude, would still prefer it over company. If Sonic himself had been in his buddy’s shoes, he would’ve spent all the time hanging with as many people as he could. Of course, there was the whole “duty of the guardian of the Master Emerald” thing, but even then would it have hurted the red echidna to just ask Sonic or anyone else to come by and hang on the island? It was big enough to freely explore and have fun in, so why? Why all this reclusion? The more Sonic thought about it, the oddly sadder he felt. It wasn’t like he didn’t hang around with the others, but… there was something about Knuckles that made him want him to be at his side. He sighed as he arrived at the shores of the island and started making his way through the forest.


After a bit of traveling past the forest, greeting all the wildlife living there carefree, Sonic reached the huge staircase leading to the Master Altar. Sonic zoomed up the stairs no problem, but when he got up he found something weird: the Master Emerald was there, on the altar, unscathed and unstolen. Sonic walked around it, checking if something, anything, was wrong, but nothing. Not a scratch, not a stain on the giant gem. The only thing missing, in fact, was its guardian.
“...Knuckles? Knuuuuckles! Where are ya, red?!” Sonic called him out, still circling the Emerald, when he noticed a cave in the mountain. He had been on this island enough times to know that that wasn’t there before, so he zoomed past the altar and headed for the mountain, scaling it and reaching the cave.
“Helloooooo? Anyone home?” he asked, knocking on the rock before venturing inside the cave. As he did, he found some writings on the wall. Ancient Echidna hieroglyphs that he could somewhat understand thanks to Knuckles showing him the meaning. Apparently this cave was called The Cave of Purging and it was used by the Echidna tribe once a month to purge themselves of… The rest was ruined and he couldn’t read it well, but it got Sonic thinking. What if this was the reason Knuckles could never hang with the others? Because he constantly needed to purge himself of… something? Was the Echidna tribe under some sort of curse? As he traveled forward, he saw more hieroglyphs completed with drawings. They depicted an ancient war between the Echidna tribe and another Mobian tribe, which forced the Echidnas to use the Master Emerald and Chaos Emeralds in order to chase them away from their plain of existence. According to the drawings this tribe was very violent and had shed much Mobian blood, especially the Echidna’s, to satisfy its urge to conquer all that existed. Apparently this tribe, more ancient than the Echidnas, was composed of a special race of Mobians whose lower half was serpentine. The Echidnas called them Naga, which Sonic knew that translated into “blood-lusted conquerors” because he had caught Knuckles swearing to Eggman by calling him that. Sonic felt a shiver go down his spine, unusual for him since he never feared anything, but this story was somewhat bone-chilling: a race so violent, so driven by their thirst for power, that forced the Echidna to rely on the Chaos Emeralds to exile them into a no-return limbo.


Suddenly, he froze. He heard something. A low growl, coming from the depths of the cave, followed by another sound that… Sonic had definitely never heard before. It was somewhat muffled so he couldn’t hear it well, but it sounded like something very heavy being repeatedly dragged and thumped across a room. Curiosity got the best of him as he carefully proceeded forward, even someone as speed-loving as him knew that this odd situation required some level of caution. Slowly, he reached the end of the cave, composed of a hole in the rock giving into a huge semi-spherical chamber. Sonic hid behind the crude door and peeked past it, seeing a figure hidden in the shadow. Sonic gulped softly: that thing was huge! A tangled, shifting mass whose girth vastly surpassed Sonic’s own body length and that occupied most of the rather huge room with its length. He spotted something moving independently from the mass, recognizing it as a tail tip of sorts, making him cover his mouth: now that his eyes got used to the dark, he could see that the figure was definitely serpentine. A Naga. A rather big one, too. The huge body was of a red color with a curious white pattern on its back, which Sonic swore he had seen before, and a peach underbelly. The creature made a deep, low-pitched growl as its body shifted and rolled across the floor, it was like it was wrapped around itself. In all of this, though, something concerned Sonic: where was Knuckles? He shook off the idea that the creature had bested him, there was no way that Knuckles would lose to such a monster despite its girth, and decided to face the creature. He slapped his face a few times to calm himself, took a deep breath and dashed in.
“Hey! Who are you? What are you doing here? What have you done to my buddy?” Sonic shouted, his voice echoed in the chamber. The creature froze, its massive body shifted and its Mobian upper half rose. As it did, Sonic’s eyes shrunk to the size of pinpricks and he left his mouth open. Not because it raised its Mobian half far above Sonic’s height, not because it showed how long and massive its body was as it unraveled. No, he was shocked because he recognized the Mobian attached to that massive snake body. A red Mobian with long dreads coming from the back of its head.
“...K…Knuckles…?” Sonic asked, shivering as he watched what definitely looked like his friend but with longer hair and a much more buff frame stretching his muscular arms while yawning loud, that sound too echoed in the chamber. The Naga glanced at Sonic with the corner of his eye, his bright blue eyes showed a slit pupil which shrunk as he spotted the blue hedgehog.
“...No…” he said, his voice quivered as his body was coursed with a violent shudder, making the huge red coils ripple and glide across the rock with that smooth sound Sonic heard before.
“NO!!” he then shouted, dashing at Sonic with a speed he wasn’t prepared for and grabbing him by the neck, pinning him to the wall a few feet off the ground.




“WHAT ARE YOU DOING HERE?!” shouted the guy who Sonic, now, could definitely tell it was Knuckles. His eyes, his muzzle, his mouth contorted into a grimace of… not anger, but shock and fear parading as anger. Sonic gritted his teeth and grasped at Knuckles’ huge hand grabbing his neck, his fingers clawing at his gloveless hand while his feet kicked in the air. Knuckles breathed through his gritting teeth a few times, then pressed his hand harder on Sonic’s throat, the other hand clenched into a fist.
“ANSWER ME!!” Knuckles growled again. Sonic gagged as he couldn’t breathe for a few seconds, then opened an eye… and saw that Knuckles’ eyes were bulging and red, two small stream of tears flowing down to the side of his eyes and his chest contracting and shuddering as if he had been sobbing the whole time.
“Ghk… I… I saw A-Angel Island… N-Not floating and… I-I was w-worried…” Sonic croaked, barely able to speak with how crazy strong Knuckles’ group on his throat was. Knuckles’ eyes quickly flashed down and back up at Sonic as his grip loosened just enough to make the hedgehog breathe.
“...W-Well, you shouldn’t have… I’m fine…” Knuckles grunted, using his other hand to quickly wipe his eyes.
“R-Right… B-Because all of this is fine…” Sonic groaned, using his foot to trace down from Knuckles’ waist to the lengths of red tail covering the floor, rippling and rolling like waves of a stormy sea.
“It is fine! And will be, as soon as you leave.” Knuckles snarled, gritting his teeth.
“Mfgh… P-Put me down first, knuckle-head…” Sonic grunted, trying and failing to pry Knuckles’ hand from his throat. Knuckles huffed and moved away from the wall, lowering his Mobian half until he was safe to let go of Sonic, making him land with a soft thud as he massaged his throat, while Knuckles turned his back to Sonic.
“...Did I… hurt you?” he asked, glancing at him with the side of his eyes.
“HHRRMM… N-No, just… caught me off guard, is all…” Sonic cleared his throat.
“Good. Now… Get out.” Knuckles sighed as he showed Sonic the door.
“...Why?” asked the hedgehog.
“Because I said so.” grunted the echidna.
“That’s not an answer.”  Sonic replied, stubbornly. “Wanna see which one of us can be the most stubborn? You’re on, Knux. I’m not leaving until you answer me.” he added. 


Knuckles gritted his teeth and clenched his hands on his folded arms.
“It’s… not safe for you to be near me when I’m like… like this…” he huffed, still not looking at Sonic.
“Why?” Sonic asked again. Knuckles growled again and turned to face him.
“Dammit, Sonic! I’m trying to keep you safe!” he shouted.
“From who? Yourself? Or the naga?” asked Sonic, folding his arms.
“YES! EXACTLY!” Knuckles shouted again.
“I can take care of myself, thankyouverymuch.” Sonic replied with a shrug.
“Not from this! You… You don’t understand…” Knuckles shuddered again, looking at his hands.
“Then make me understand.” said Sonic, sitting down in front of him.
“Here. Now.” Sonic urged Knuckles, slapping his open hand on the floor.
“You can’t make me… Please…” Knuckles whined.
“Ho ho, now I’m more than convinced something’s wrong, knuckle-head.” Sonic replied with a fake smirk, hearing Knuckles say “Please” truly convinced him that he needed to open up.
“N-No!” Knuckles roared and lunged at Sonic, who simply dodged and landed on Knuckles’ snake tail’s back, cooing slightly as his new upper body was incredibly fat and squishy, enough for his rear to sink into it.
“W-Woah…” he said, struggling to stay still as Knuckle pointed at him.
“Get off me!” he growled.
“Make me.” Sonic replied smugly. Knuckles clenched his fists and tried to lunge at him again, but Sonic simply rolled off the coil he was on and landed on another section of Knuckles’ body below him. Knuckles hissed and lunged again and again, but everytime Sonic would just dodge his attacks and kept doing so until Knuckles visibly slowed down, panting and grunting as he was covered in sweat. Sonic jumped and landed in front of him, his arms folded.
“New body, same old Knux.” he sneered, then he became serious again and kneeled down to better look at him in his eyes. 
“Still not willing to explain?” asked Sonic, not at all intimidated by Knuckles’ tired glare.
“W-Why do you c-care so m-much…?” Knuckles panted as he got up on his arms.
“Because you’re my friend, duh.” Sonic groaned, knocking on Knuckles’ head.
“When will you understand? Me and the others care about you and the more you push us away, the more we’ll want to be close to you, to help you.” he added.
“... Then… If I tell you… Will you leave me be?” Knuckles grunted as he got up on a section of his snake body.
“If it’s what you wish, yes.” said Sonic, sitting back down.
“...Very well… But you must not tell a soul about this.” Knuckles sighed.
“It’s gonna be our secret.” Sonic nodded, smiling reassuringly.


“...Sigh… Since you came in here, I assume you read about my kind’s quarrel with the nagas, many centuries ago.” said Knuckles, and Sonic nodded.
“It was a long, grueling battle which took place on the ancient continent of which Angel Island is the sole remain.” said the echidna, at which Sonic flickered an ear: Angel Island was a continent?
“Yes, it used to be connected to the Starfall Islands. I discovered this during my studies of their architecture, very similar to that of my kind. It turned out that the Ancients and the Echidnas had lived together in peace until The End came to destroy them.” Knuckles recounted and Sonic quietly listened
“As it did, that entity brought us the scourge of Nagas. They were its followers and, as such, refractory to the Chaos Energy. However, thanks to their half-Mobian nature, they were also attracted by it. So, they decided to seize it so that they alone could use their power, even if it meant weakening themselves.” Knuckles clenched his fist as he spoke.
“And thus, the war between our kind sparkled. For every Naga we slain, they could simply birth more by infecting others with their venomous bite. On the other hand, they were very effective in slaining us, despite us using what they described as ‘everything our master despises’. But in the end, it was the Master Emerald that saved us. Pachacamac’s father was the one who invented the formula to awaken the Master Emerald, using its power to conjure up a dimension from which those monsters could never return and tossing them into it. However their queen, the malefic Kalimah, had already contaminated many of our kind with her poison.” Knuckles said, lowering his head and gritting his teeth.
“I see. So, that’s why you are like this.” said Sonic. Knuckles nodded silently, taking a pause to breathe before continuing. “My ancestors had been poisoned by Kalimah’s venom and thus had been turned to Nagas, cursed to pass their fate to their offspirngs. However, thanks to their affiliation to the Chaos Emeralds and because Kalimah had been sealed away, her influence could not poison their minds. But they were still ostracized by their kind, who saw them as monsters worthy only of being sent to the same hellish limbo as the others. However, a young Pachacamac, not yet consumed by greed, was the one who stepped up, believing them to be victims, not monsters. His father approved of his ideas and thus my family had been permitted to live among others. The Cave of Purging was built for the sole purpose of… safe reproduction.” Knuckles concluded, looking away with a small blush tainting his cheeks.
“Huh?” asked Sonic.
“Huff… The Naga influence, albeit weak, was still present, and manifested as uncontrollable fits of lust which pester us every month, leaving us unable to control our physical shapes with Chaos Energy and driving us mad with… questionable thoughts… Basically, once a month, I need to retire here to… relieve myself while my ancestors came here to conceive and give birth to their offspring safely.” concluded the echidna, drooping his head.


Sonic blinked a few times, assimilating the massive bomb Knuckles dropped on him.
“So, you come here once per month… to masturbate?” he asked, making Knuckles cringe.
“Urgh, always the indelicate one… B-But yes, basically…” Knuckles huffed, blushing more.
“And like this you can relieve your body and soul of the lustful thoughts given to you by your Naga DNA, right?” Sonic asked again.
“Precisely. If I don’t do this… I might attack one of you and… violate you. Not just females, even males wouldn’t be safe. My lust is uncontrollable when I’m in this state, and even if I can’t turn you into a naga if I bite you, since the venom has long lost its efficacy, I could still do damage to everyone around me. I’m a monster…” Knuckles sighed as he looked at his shaky hands.
“You seem perfectly fine to me, now…” said Sonic, raising a brow.
“Because I… Uh-Uhm… J-Just finished… relieving myself when you barged in…” Knuckles scoffed, blushing.
“Oh… Wait, then it’s all done, right?” asked Sonic, diverting his look to the rest of the giant room.
“No, Sonic… I have to spend 24 hours in this room, by myself, constantly masturb-I mean, relieving myself until the sun sets and rises up again. If I leave any sooner, I might get into a frenzy. You just being here puts yourself in grave danger.” Knuckles stated, groaning.
“I see now. This really sucks, man. I wish there was something, anything I could do to help you.” said Sonic, sighing and rubbing the back of his head.
“Unfortunately, there’s not much known about the Naga curse, because all registers about Nagas had been destroyed when Chaos slaughtered my ancestors. All I know is that not even my own Chaos Energy can get rid of it. I know, I tried…” Knuckles sighed, looking at his hands and dropping his head again.
“...What if it’s the Chaos Energy from someone else?” asked Sonic, making Knuckles look up.
“Yeah, I mean… Maybe your own energy doesn’t work because the curse has adapted to your body… But, and it’s a big but, what if it receives stimulation from an outside use of Chaos?” asked Sonic. Knuckles widened his eyes.
“I… I never thought about it! Gah, so stupid! I really AM just a dumb knuckle-head…” he groaned, slapping his face.
“I mean, it’s a theory, I don’t know if it would work, but…”
“It’s worth a shot!” said Knuckles, leaning towards Sonic, making him wince a bit. Knuckles had never been so close before and, with how exotic his eyes looked and how giddy he sounded, Sonic felt his heart jump a bit. Had he always looked so… appealing before?
“There’s no time to lose! I don’t know when I might lose my mind again and become aggressive! Quick, go absorb some Chaos Energy from the Master Emerald and get back here!” said Knuckles in a hurry. Sonic nodded and dashed outside, going back to the altar. As he did, he began to feel all kinds of feelings: he felt sorry for Knuckles to have suffered this curse alone all this time, he felt angry at the Nagas for cursing his friend, but also he felt curious as to why would he find Knuckles attractive. They had spent a lot of time together before, so his sudden interest in Knuckles was confusing him. He never thought that he might’ve been attracted to him before. A cute red colored his cheeks as he reached the Emerald, imposing his hand on it and chanting the old prayer:
“The servers are the seven Chaos.
Chaos is power. Power enriched by the heart.
The controller is the one that unifies the Chaos.
O bringer of Chaos, please lend me your power, so I may relieve my friend’s pain.”. As he did, his hands sizzled as the green glow of Chaos flowed into his arms, gathering at the center of his body as a pulsing green core.


“Sweet!” he said, running back to Knuckles. As he did, however, he found him lying on the ground, holding his head and growling as if he had a headache.
“Knux!” Sonic ran at him but he stretched a hand to stop him.
“Uuuurrrrgggghhhh… It’s… I-It’s c-coming…” he gurgled, drooling as his only open eye showed his pupil becoming bigger as it fixated on Sonic.
“D-Don’t get t-too close, or you… You… … … You smell nice…” Knuckles switched tone between words, starting in pain and ending with a strange pitch in his voice. He raised his head, moving his hands away and looking at Sonic, both his eyes staring intensely at him as a grin formed on his face.
“Have you always smelled this nice, hedgehog?” said the echidna as Sonic took a small step back.
“Uuhh… K-Knux? You… You still there?” asked Sonic, concerned as to why Knuckles would compliment his smell.
“Of courssssssssse.” The ominous hiss more than confirmed that he couldn’t control his own lust anymore.
“You worked sssssso hard for me, I want to thank you. Come here and give me a hug.” he said, spreading his buff arms, showing his huge glistening pecs.
“Uh… I-I’m good, Knux… L-let me just… Get everything ready for t-the transfer and…” he was interrupted as Knuckles slithered behind him, using his body to block the entrance and grabbing Sonic’s shoulders, taking a long, slow sniff of Sonic’s quills, making him squeak as his fur stood up.
“Mmmm… Such a… deliciousssss sssssmell…” Knuckles purred right in Sonic’s ear, making him shiver: he didn’t know that Knuckles’ voice could sound so suave and yet so intimidating. He saw he was cornered by a giant loop of Knuckles’ gigantic coils, dwarfing Sonic in size as they were much taller than him. In comparison, Knuckles’ upper half looked ridiculous with how small it was.
“Mmm… Pleasssssse, ssssstay with me, Ssssssonic… I need you…” Knuckles purred again as he slid his arms around Sonic’s neck and chest, pulling him into a hug. Sonic felt his heartbeat increase as Knuckles pressed him against his buffer body, feeling how rock hard and hot his muscles felt against his back. Sonic groaned and placed a hand on Knuckles’ left arm wrapped right below his armpits to try and the other hand on his cheek to try and pry him off as the lust-driven echidna served himself to more sensual sniffs of Sonic’s hair.


“Uuuhhh… M-Mmh… Uh, K-Knux, I… I don’t feel quite comfortable doing this…” Sonic groaned as he tried to push him away.
“Hihihi, oh, I sssssssee… You wanna play a game with me, right?” chuckled Knuckles, hugging Sonic tighter and beginning to lick his neck.
“I-I didn’t say th-aaaah!” Sonic shivered as he felt Knuckles’ hot tongue drag across his neck.
“You didn’t ssssssay it… But your body issssss more honessssst than your mind…” he said grinning and continuing to lick, as Sonic struggled more in the feisty echidna’s grip. Knuckles’ left hand began to knead Sonic’s chest, which made Sonic bite his lip to try and not moan, thus giving him more reasons to keep doing this.
“You can’t control it… You can’t deny it… Your passssssion… I can feel it in your ssssscent…” Knuckles whispered into Sonic’s ear, shifting his attention to it as he began to lick and nibble it, making the blue hero moan under his sealed lips since his ears were sensitive.
“Found a weak sssssspot… And here’sssss another…” he hissed as he nibbled his ear and pinched Sonic’s nipple, making him thrash more wildly in his grip.
“K-Knuckles, I’m s-serious. P-Please, stop!” Sonic grunted and kicked a bit as Knuckles lifted him up slightly.
“I’m ssssseriousssss too, Sssssonic. My friend, my confidant…” Knuckles kept whispering and, as he did, the coil which he used to trap Sonic closed in on him, trapping everything from below Sonic’s armpits into a singular, huge coil.
“WHUGH!” Sonic wheezed as the coil closing on him made him exhale a bit.
“...MY plaything…” Knuckles hissed more and grinned as Sonic got trapped. The echidna went in front of Sonic, his hands holding his wrists now, and grinned as the blue hedgehog squirmed and struggled. Sonic gritted his teeth, feeling Knuckles’ huge body pinning most of him, so pudgy and yet strong. He tried to kick or move his legs, but every movement was almost absorbed and nullified by the huge coil. He felt the squishy underbelly pressing behind his head as he couldn’t feel anything below him. Just an abyss made of the huge coil Knuckles trapped him into.
“N-Nngghh!! Rrgghh… K-Knux, let me go!” Sonic groaned as he tried to free his hands from Knuckles’ grip.
“...No.” he simply said, smirking as he came close.
“W-What do you mean?” Sonic asked, cold sweat trickled down his face.
“I mean… No.” Knuckles said before moving forward and planting the deepest, most weirdly hot kiss Sonic had ever received on his lips before. His first kiss.


Sonic widened his eyes as Knuckles kept his hands steady while kissing him right on his lips. The kiss… Sonic couldn’t stop thinking about it. Knuckles’ lips felt hot, like his entire body, and incredibly soft despite his ruggedness. Knuckles tilted his head, which gave him a better access to Sonic’s mouth, and deepened the kiss, adding his tongue to the action. He let go of Sonic’s hands to cup his cheeks, and Sonic took the chance to grab Knuckles’ shoulder and… then? He had no way to outstrength Knuckles, besides the warmth and odd coziness radiating from his body made him begin to feel safe, despite knowing that Knuckles wasn’t doing this out of his own mind, he had been taken over by the Naga’s lust. He just held onto him, moaning as he slowly returned the kiss. Their tongues wrestled with each other but Knuckles’ own tongue quickly won the war because his was longer and could coil around Sonic’s tongue, stroking it. Knuckles moved his lips away but their tongues continued to wrap and coil around each other, Sonic’s muzzle was completely red out of embarrassment and pleasure. Knuckles smiled and felt his cheeks with his big hands cupping Sonic’s face, then pushed him back in for the kiss, going even deeper this time. 
“M-M-MMMPPPHHH!!!” Sonic moaned much louder this time, even though it was stifled by the kiss and his hands lost their grip on Knuckles’ shoulders, resting atop the huge coil trapping the rest of him. Knuckles opened his eyes and stared intensely at Sonic, pulling away and licking his lips as he watched, smirking, his catch pant and moan, his turned on face covered in drool and sweat as the warmth radiating from Knuckles was too intense.
“Hah… Hah… Hah… K… K… K-Knuckles-s-s-s…” Sonic moaned, shivering.
“My my… Never thought you could look sssssso pretty in my eyesss, Ssssonic…” Knuckles chuckled and rubbed Sonic’s cheek, catching a single tear of bliss beginning to form under his eyes.
“Something assssss… Interesssssting asssss you… Shouldn’t be left on the loossssse…” he chuckled as he grabbed Sonic’s arms and shoved them inside the coil, which pinned them at his sides, effortlessly robbing Sonic of any movement. Sonic groaned and tried to free himself, but it was as pointless as fighting a tide with a rock. The coil clenched just enough to make sure Knuckles’ prey wasn’t going anywhere.
“There we go, much better.” Knuckles said satisfied as he watched for a few moments Sonic’s attempts to wiggle out of the coil prison he was trapped in.
“Ngh… Ugh… Mgh…” Sonic quietly groaned as he couldn’t even make the coil budge. Never before had he felt so tiny and powerless against anyone else. 


“Sssstill… I think we can do better, no?” Knuckles asking made Sonic stop squirming and looking up at him, staring down at Sonic with a puzzled expression. It was then that Sonic felt something slither around his ankle, coiling around both of them and sealing them together. He gritted his teeth: Knuckles was using his tail to coil him up even further. he could feel the appendage scale his body, throwing loop after loop around him and painstakingly slowly dragging inch after inch of his length around him. The coils grew thicker with each loop wound around Sonic’s helpless body, increasing not only the pressure, but also the heat. Sonic began feeling even more hot as the tail wrapped him up to his groin, moaning as the tail fiddled with the space between his legs until something hard grew out of it.
“There it isssss…” Knuckles chuckled as the tail coiled around Sonic’s bulging member thrice before going back to wrap around the rest of him, scaling his plain belly.
“K-Knuckles, s-sto-o-op…!” Sonic cried out as the tail holding his cock almost scorched him with how hot he was running.
“It’ssss a bit too late to ssssstop now…” the echidna simply replied with a shrug as he continued to coil Sonic up.
“How doessssss it feel? Isssss my body hot, sssssoft and sssssquishy enough for you?” he then asked grinning as he could feel Sonic sweating a lot inside the coils, greedily kneading and groping his form as they scaled his body. Soon, everything that was trapped inside the huge coil had been wrapped up by the tail, which began to pour out of the coil and wrap around Sonic’s neck, going over it and digging back inside the loop of scales and muscles, coiling downwards. Sonic groaned as, with every loop it threw at him, he could feel the older ones growing thicker and thicker. Especially, the one at his neck looked like it was inflating with how big it was getting. Soon, his face was squished by the coil as the tail finished winding up around him, having cocooned him even further inside the huge coil.
“Hehehehe… Now that’sssss more like it… You look ssssso comfortable and warm wrapped by my tail, Ssssonic. Don’t you jusssst wish you could sssstay like thissss… Forever?” asked Knuckles, grinning.
“M-Mmmggghhh…” Sonic could only gurgle as the coils impeded his speech. Everything felt so tight and warm, Sonic wondered if this was what burritos felt. He didn’t know how Knuckles’ body could be so hot, but this warmth was dangerously driving him closer to falling asleep. If he did that, who knows what Knuckles would’ve done to him, so Sonic fought the growing need to fall asleep, struggling against  tiredness he never thought could catch up to him.
“You ssssstill ressssisssst… Heh, very well. There’sssss more than one way of putting a hedgehog to ssssssleep…” Knuckles sneered as his body began to soothingly roll, ripple and knead Sonic’s body, massaging him by tightening and loosening ever so slightly. A moan escaped his lips as Knuckles’ coils tended to him in such a loving way he couldn’t hold on a purr.
“Heh, look at you. You look ssssso sssssmall, ssssssso weak, sssssso defensssselessss… Ssssso… Adorable…” Knuckles whispered, coming closer to Sonic since the sound of the coils dragging across him deafened everything else. Sonic squeaked weakly as he began to feel good, especially his cock since Knuckles began stroking it with his tail, moving it up and down slowly.
“Like it? I do thissss to mysssssself everytime I’m in thisssss room… It alwayssssss feelsssss ssssso good, I sssssometimesssss fear of going insssssane jussssst by rubbing and sssssstroking my cock like thissss with my tail…” he giggled as he lied on the huge coil with his crossed arms, laying his chin on his arms as he stared at Sonic moaning and panting as he endured the sensual massage.


Sonic gritted his teeth as the massage went on, unwillingly relaxing him while also turning him on. His cock already twitched as Knuckles’ tail skillfully rubbed it while his muscles loosened as the coils tightened and loosened rhythmically around him. Knuckles grinned as he suddenly squeezed Sonic tight, not relenting. That made him moan, arching his back as he wheezed. The coil around his neck almost inflated, like an air pillow, cutting his breathing short. The rest of the coils flexed and grinded around his body, pushing his shoulders inwards as the skin of his arms bulged. Then, the huge coil tightened too. Sonic widened his eyes and gagged since, like this, no air could get in his lungs. The coil creaked and growled as it corkscrewed tighter around Sonic’s bound body, then it got lifted as another coil was laid below it, and then another. Sonic was now atop a huge coil pyramid, his head a blue and pink speck compared to the bulk of the coils holding him, tightening and squeezing him ever so stronger. He gagged again, his eyes rolled to the back of his head and his cheeks turned redder from the pressure.
“Hihihi, I do love your gagging face… Your struggle to breathe… It’s intoxicating…” Knuckles purred before he went for another kiss, this one felt even more intimate somehow despite the impending blacking out. Then, air was puffed into his lungs. It was warmer and tasted of grapes, but it was breathable and slightly jolted him awake, making him struggle weakly as he continued to be squeezed and stroked, his cock never going limp even after all of this. Was Sonic really into this? Knuckles kept kissing and puffing air into his lungs, stroking his hair and cheeks as he kept constricting Sonic, then he smirked and moved away, giving him one last powerful squeeze which made Sonic’s bones creak ominously before finally loosening enough to let him breathe. The blue hero drew in as much air as he could while the coil framing his face squished and massaged his cheeks. He panted deeply and opened an eye, all misty and watery due to the pressure from earlier, seeing Knuckles’ grin all over his face. He raised his waist and pointed his cock in Sonic’s face. That made him open his other eye: Knuckles’ cock was huge, thick and veiny and he could smell its powerful, manly scent which made him tremble. 
“Guesssssss what’ll happen next…” he chuckled and rubbed his cock all over Sonic’s face, making him feel how hard and hot it felt. Sonic’s body was now drenched in sweat, making the coils glide easier around him, and his cock twitched madly, but the coil around its root tightened so that he couldn’t cum. Not yet, at least.
“I’ll make you mine… Every hole in your body… I’ll use it… Brand your orificessssss with my dick and make sssssure you can’t ever be sssssatissssfied again unlesssss it’sssss me. Open wide, my lovely ssssslut…” Knuckles grinned evilly and suavely as he pushed his cock into Sonic’s agape mouth, he would've closed it but he was still recovering his breath.


Sonic’s senses were assaulted by Knuckles’ cock. It felt as hot as his coils, its powerful smell burned itself in Sonic’s nostrils and it tasted salty and bitter, stretching his mouth with its girth.
“M-MMGGHHLLGGHH…!!” Sonic gurgled as he got a mouthful of Knuckles’ cock.
“Hhhnnnfff… Ssssnug fit…” cooed the red naga, smirking as he began to hump Sonic’s mouth, the tip of his cock edging towards the entrance of the blue hedgehog’s throat. Sonic gagged and gurgled more, drooling a lot as Knuyckles facefucked him, something he would’ve never thought would happen… and somehow, something that still turned him on. The mere feeling of being unable to do shit while Knuckles used his m,outh as he pleased… A purr escaped Sonic’s lips, making Knuckles smirk wider.
“If you like it sssssso much, get to work. Sssssuck me off, make me busssst a nut in your mouth…” he hissed and Sonic, almost feeling obliged, began to suck and lick the massive cock jammed in his mouth, savoring it and getting used to the raw taste and intoxicating smell. Everything about what was happening to him made him go wild. He had never experienced something so pleasurable in his entire life, having never even masturbated before. His assaulted cock throbbed and trembled as Knuckles’ tail kept fapping and squeezing it, making him moan on the cock he was sucking as some precum leaked out from both Knuckles’ and Sonic’s own cock.
“Huhuhu, you’re sssso good at thisss… You ssssure it’ssss your firsssst time?” asked Knuckles, chuckling as he held Sonic’s head and slammed his girthy cock in harder, makign Sonic deepthroat it. That’s when he lost it. Feeling the massive cock stretching his mouth and throat, making him able to breathe only from his nose had him moan even louder.
“Heh, guess who’s into being choked… Hmmm…” said Knuckles, grinning as he withdrew his cock enough to make Sonic breathe.
“Take a DEEP breath, my ssssweet sssslut…” he chuckled then, at the same time, slammed his cock back in Sonic’s throat and resumed squeezing him again, completely cutting off his air. Sonic widened his eyes and shouted blissfully as Knuckles pressed his head on his own groin, burying his cock as deep as possible in the hedgehog’s throat and humping his mouth, leaving almost no space between humps.
“Hah… Hah… Hah… Hah… I… I’m going to cum, Ssssonic… When I do, I’ll let you cum… I want ussss to cum together, Ssssonic…” Knucklels began moaning as he facefucked and constricted Sonic. The blue hero teared up in bliss as his body was being used like this and he didn’t knew why he loved this so much but he kinda wished this wouldn’t stop, only being reminded of Knuckles’ condition by the Chaos Energy pulsing in his chest, almost scolding him for thinking that Knuckles would actually do this to him. Knuckles humped him a few times and then, almost in sync, released Sonic’s cock as he nutted deep down his throat, squeezing him as hard as possible without breaking him. Sonic made the most indescribable noise ever as he was forced to swallow the thick, creamy load flooding his mouth and as he came too, pouring a big load into Knuckles’ greedy coils, clenching tiger around Sonic as he came. Knuckles huffed and growled as he came deep into Sonic’s mouth, then pulled out with a  loud POP and panted, his cock still hard and twitching as some spurts of cum splattered on Sonic’s ahegao face, he too panted harshly as the squeeze ended, his muzzle was fully red and stained with cum, tears and drool. Knuckles chuckled and waited a few moments, more so to ready himself for round 2 than waiting for Sonic to calm down.


As Sonic seemed to calm down, Knuckles seemingly vanished somewhere below the coil pyramid. Still panting, Sonic looked around, seeing nothing except the rocky walls of the Cave of Purging and the seemingly infinite ocean of red and white coils rolling around him, needingly pressing against him like Amy did whenever she hugged him, except it felt way more tight, squishy and… wanted than the needy pink hedgehog’s shows of affection. Amy… So that was why Sonic was never interested in her. He was homosexual the whole time and never knew. His thoughts froze as he felt something scale his bounded legs. He squirmed some more against his pudgy bindings, thinking that he was going to be so sore and cramped once Knuckles would let him go… IF he ever let him go. His Naga lust seemed to have fully taken over and he feared that the Knuckles he once knew would never return. He needed to act quick and recite the formula before Knuckles would overwhelm him again.
“Hah… Hah… Hah… Head… F-Fuzzy… S-Spinning… N-Need to… th-think… N-need to… r-remember th-the f-formula-ah…” Sonic moaned, still lightheaded after being squeezed and facefucked before, when the tail tip slithered out of the giant coil again and shoved itself in his mouth, gagging him again.
“MGH?! MMMBBBGGGHHH!!!” he groaned and tried to shake his head to get it out, when he felt Knuckles' strong arms wrap around his chest.
“You’re too ssssslow…” he whispered in his ear, making Sonic whine.
“Did you really think I would let you do shit? A Naga’sssss mate workssss bessssst if he’sssss ssssseen, not heard… Unlesssss the Naga wantsssss to hear hisssss ssssslutty moansssss assess he getssss plowed…” Knuckles hissed in Sonic’s ear, while pressing his meaty boner against Sonic’s ass, which he freed by pulling down one of the coils.
“MMMFFFGGGHHH!!! MMMBBBGGGHHH!!!” Sonic moaned and squirmed more, feeling that thing prodding one of his asscheeks.
“You’re a sssssquirmer… I love it… And you got ssssso much cushion for pushin’, back there…” Knuckles hissed in delight as he nibbled the tip of Sonic’s ear, making him moan again as his cock resumed being fapped by the coils holding it hostage.
“Get ready to go crazy… Once I’m done with you, you’ll be completely mine, hedgehog… Like it wassss meant to be…” Knuckles kept hissing and whispering in Sonic’s ear, which made his fur stand up and his blush intensify. He needed to remind himself that the real Knuckles would never do this, that this was just the lust of his naga half speaking and that he needed to endure this until he’d find another window to recite the chant and save Knuckles from himself. Knuckles’ tail tip pushed more into Sonic’s mouth, making him gurgle as he was snapped back to reality, the coils massaging his cock went faster, making him moan, and then Knuckles aimed his cock towards Sonic’s entrance and pushed it in.


“MMMMM!!!!!” Sonic shouted and squirmed as Knuckles’ cock stretched his asshole wide with its girth. 
“Unf… An even sssssnugger fit…” Knuckles grumbled as he pushed his tip inside, then began to try and push more of it in. Sonic squirmed much more now, feeling the sting of the large insertion in his hindquarters.
“Hold ssssstill or it’ll only hurt more…” huffed Knuckles, tightening his grip on Sonic with both his arms wrapped around the hedgehog’s chest and the coils all around him. Sonic groaned and stopped moving, then Knuckles smirked and managed to push more of his cock in, getting half of it inside Sonic’s ass. That alone made Sonic sob slightly since it hurted and stretched his asshole much more than usual.
“Heh, much better.” said the lustful echidna as he began to hump Sonic’s ass, making him moan and struggle more as his entire body was being used by the naga. His cock got fapped very fast, his body being hugged and squeezed by Knuckles’ buff arms and fat coils, his mouth got full of snake tail and his ass was being plowed mercilessly by Knuckles’ huge cock.
“Ungh! Ungh! Ungh! Sssso tight, wet and warm insssside… Your asssss issss truly grade-A, Sssssonic!” Knuckles moaned as he pushed his tongue inside Sonic’s ear, thus adding yet another stimulus to the mix which was driving Sonic crazy. Soon, the pain was replaced with a pleasure so intense it was about to turn Sonic’s brain into mush. Jolts of bliss shot up his spine whenever Knuckles would hit him the deepest, making him moan sluttily as he sucked the thick tail pouring in his mouth and stuffing his cheeks. Sonic began to hump into the coils massaging his cock and began to relax his ass, thus letting Knuckles in deeper. The huge naga chuckled and pushed all of his length inside Sonic’s ass, making him throw his head back and yell in bliss as Knuckles stuffed him.
“MMMFFFHHH… MMMFFFHHH… SH… SH… SHQUEESHE M-MEEEH…” he managed to splutter, drool messing up his muzzle.
“...Heh, assss you wish…” Knuckles grinned and tightened his grip, bearhugging Sonic’s chest and squeezing the rest of him with his coils. Sonic gurgled and gagged as Knuckles used him completely, making him feel the most wicked pleasure he could’ve wished for. Sonic came not too after, shuddering and gurgling as his cum flowed out of his still stimulated penis.
“Huhuhu., you came firsssst… Fasssstesssst Thing Alive, indeed…” Knuckles sneered and kept ramming Sonic hard, his meat slapping hard against Sonic’s rear, the inner walls squishing and squelching around Knuckles' massive member which began to throb after five minutes.
“Ungh! Ungh! I’m cumming, Sssssonic! I’m cumming! I’ll brand you with my sssseed!” Knuckles growled before burying his cock as deep as he could in Sonic’s ass and flooding it with an even bigger load than the one released in his mouth, followed by the tightest squeeze from both his arms and his coils. Sonic made yet another sound which words alone could not describe, except for how loud it was or how lewd it sounded as he came again, feeling the massive load stuff his belly, sloshing in his stomach, while his bones strained against the insane pressure until a couple of ribs gave up and cracked, causing Sonic to tear up even more in a mix of pain and pleasure he wasn’t sure he’d ever recognize after this.


“Huff… Huff… Whew, you are really ssssomething elssssse!” Knuckles chuckled as the orgasm finished and pulled out with an even louder POP as he moved to the front of Sonic, still hugging his chest and pressing his won, buff pecs against Sonic’s. The blue hedgehog had never felt so tired in his entire life, not even after running the whole day. His body was covered in sweat, tears, drool and cum, everything hurted and yet at the same time felt good. Knuckles squished his chest on Sonic’s a bit to make him look up, moaning as their nipples pressed against each other.
“Well, wassss that sssso bad?” Knuckles asked with a smirk. Sonic didn’t answer, too busy panting through the tail still stuffing his mouth.
“Heh, I guess you’re cooked now…” giggled the echidna as the tail pulled out, making Sonic inhale sharply and cough as it settled around one of his eyes.
“Bet you’re ssssso addicted to me you can’t think sssstraight… Not that you are sssstraight, anyway…” chuckled the echidna as he licked Sonic’s lips, making him purr.
“Get ussssed to thisss… Becaussse it’ll be your new norm from now on…” chuckled the echidna. It was then that the glow in Sonic’s chest pulsed more, powered up by Sonic’s heartbeat. Sonic opened the other eye, which glowed green as he began chanting “The servers are the seven Chaos. Chaos is power, enriched by the heart. The controller is the one that unifies the Chaos.”. Knuckles widened his eyes and tried to shut him up with a french kiss, but his face was repelled. It was too late.
“O power that flows into everything that lives, please cure the love of my life from his lust!” Sonic shouted, it was like he had recovered all his energy, and then the glow from his chest glowed stronger.
“N-No! Sssstop! W-What are you d-doing?!” Knuckles growled and tried to move away, but it was like he was glued to Sonic. 
“...I’m getting MY Knuckles back…” said the hero, narrowing his eyes at him as the light grew in intensity.
“NOOOOOOOOOOOOOoooooooo…” Knuckles’ shout got lost as the light shone brighter, illuminating the entire cave. Once it began to fade, Sonic squinted his eyes and saw Knuckles shielding his eyes from the light, remembering that he didn’t like direct light in his eyes. Sonic groaned as he was still almost fully buried in his coils, but as Knuckles slowly opened his eyes, the hedgehog drew a breath of relief in seeing that his pupils were normal again. Knuckles looked at Sonic, both confused and slightly scared, then looked around, as if he was listening to something.
“... … …I can’t hear it…” said Knuckles, even his voice was back to normal.
“I can’t hear it… That constant presence in my head… That pressure, that… lust, it’s… It’s gone…” he said.
“Mf… H-heh, welcome back…” chuckled Sonic, feeling the tiredness return, albeit not as strong as before. He then wheezed as Knuckles hugged him tight.
“THANK YOU, SONIC! I… I thought I would never get rid of it!” bawled the red echidna, hugging Sonic to him.
“WHUFF… Y-You’re w-welcome…” Sonic wheezed, then winced as his ribcage hurted.
“Oh sorry!” Knuckles groaned and pulled away, looking at how Sonic was coiled up.
“D-Did I…?” he asked, groaning.
“...If ya ask me… That wasn’t you…” said Sonic, shrugging.
“Though, now I see why you were so scared to begin with…” he added, chuckling weakly.
“Y-Yeah…” said the buff echidna as his hands glowed green and he imposed them on Sonic, healing him.
“Well… I guess I owe you now. Ask me anything and I’ll do it.” said Knuckles. Sonic blinked, then blushed and moved forward, giving him a gentle kiss on the lips, making Knuckles widen his eyes and purr slightly as he slowly returned it, hugging him closer.
“Just…” said Sonic, pulling away.
“...Stop pushing me away…” sighed the hedgehog, his eyes shimmering as he looked at him.
“...Heh… I won’t…” said Knuckles as he resumed kissing Sonic's lips, stroking his hair as his coils gently hugged them both. While they made out, a new engraving appeared on the wall of the Cave, glowing in the green of Chaos as it cited: “While our efforts to cancel the curse were fruitless, we were able to at least find out how to get rid of the naga’s influence forever. The method consists of letting another Chaos user imbue their own Chaos Energy into the accursed. However, the user must also declare his or her unconditional love towards the accursed for it to work.”


The End
