"Dammit, Sonic, get back here!" Knuckles yelled with outrage while he chased a fast blue hedgehog who was up to his annual jerk bag antics. "I swear, when I catch you!" He warned with a threatening growl, but it was to no avail in his hopes of stopping the speedy blue one. Sonic was playing games with the echidna, running at a low speed as he weaved in and out between a field of ancient carved pillars. It was going on two minutes since he got the knucklehead to chase after him for dumping a slush on him during his meditation. The red one was angrier than usual from that little stunt, but it was worth it to Sonic who even jumped from pillar to pillar.

"Hahah, catch me?" Sonic scoffed at his red buddy while taking a peek over his shoulder to get a fulfilling glimpse of the echidna's expression. "I could just take off and leave you in the dust if I wanted to! But this is just too much fun!" 

Oh that arrogance... Knuckles didn't like it at all, nor did he care for Sonic's obnoxious self entitlement to go around doing whatever he damn well pleased. Feelings that were accentuated by a pulsating vein bulging in his forehead above his right eye. This area of the island was a sacred place, one Knuckles would never dream of disrespecting. Sonic was going too far this time and he had to end it. "You're so going to regret this! I AM NOT HAVING FUN!"

Sonic snickered at that. "That's what makes it even more fun for me!"  He teased coldly and looked back again, only to be confused when he caught no sight of the angry guardian chasing him. "Huh? OOF!" Some air was expelled from his lungs as he ran directly into something soddenly in his way that was rather durable, but soft despite being so sturdy. Shocked, Sonic turned his head and gulped as he saw red standing right before him.

Knuckles had the idea to utilize a warp ring, warping himself right into the middle of the hedgehog's path. He put his hands out and stopped Sonic from going any further. He was the one smirking now when the blue one had a look of sudden shock and dread as he started to back up away from him.

"Aw jeeze, Knucklehead. You aren't that mad are you?" The hedgehog chuckled nervously backing away with his hands up defensively, but still being the Sonic he always was, he couldn't resist poking the metaphorical bear that was about to rip his face off.  "It's a hot day, I figured you needed a lil cool down and exercise cuz all ya were doing was sitting around in the sun like a dope!"

"Grk!" Knuckles' eyelid twitched and that vein popped in his forehead again, his blood now coming to a boil from Sonic's last remarks. "I WAS MEDITATING AND YOU DUMPED A GALON SLUSHIE ON ME!" He roared and Sonic nearly squealed when a furious spiked fist was suddenly launched forth en-rout at terrifying speeds directly to his face!

"WHOA!" That fist actually had fire on it! But the blue nuisance was lucky in that he managed to dodge it with only singing a few quills. He dove out of the fist's pathway and looked back at the echidna, who's eyes widened  as his powerful punch struck a pillar instead.  No time to retract or lessen the power behind that blow, as expected the large cylindrical sculpture outright exploded into scattered pieces!

Knuckles was left to stand slack jawed, dropping his arms like dead weight at his sides while his brain either tried to register or block out what had just happened. "...No" He muttered, staring down at the pathetic stump which was all  that was left of the beautifully engraved pillar of stone which stood tall and pristine moments ago.

Sonic was going to book it out of there, knowing from many past experiences how crazy angry the red echidna was likely to be after destroying something on his island. But he couldn't help  tilting his head at the strange sight of Knuckles' reaction this time. "Knucklehead?" He blinked at the other then stood up after he got no response from the echidna, who simply looked horrified at he damage in front of him..

It was as if Sonic was witnessing Knuckles' brain snapping within the very confines of his hardened skull, his jaw simply slack and an expression of disbelief and bewilderment etched in his face. It was actually concerning if not almost a little scary. "C'mon man... heh" The hedgehog began, sounding kind of nervous as he made his way over with baby steps "I-it's not th'end of the world, I mean... It can't be that bad if you still got a whole field of these things, right?" He asked, and placed a hand on the guardian's shoulder hoping to get Knuckles to see his lighthearted point of view.

Knuckles didn't see it from Sonic's perspective however, and something inside him snapped when the hand fell upon his shoulder, adding insult to what was being said to him. "Not a big deal?!" He roared and grabbed Sonic's wrist in a harsh grip, turning towards him with rage burning in his eyes. 

"AH!, He-hey let go!" Sonic was startled and tried to pull his hand free but the crimson echidna wasn't even letting him budge. "You're pissed, I get it! I'll just go away for a while and let you calm down in the meantime!" 

"No you don't get it, Sonic!" Knuckles retorted, seething anger and squeezing Sonic's wrist so tightly as to make the hedgehog feel pain. "I oughta punch your lights out, wake you up and punch them out again!" The echidna snarled at him. "But I know damn well throttling your face in wont make you stop acting like a big childish idiot!"

Sonic grit his teeth and groaned as the grip around his wrist truly did become so painful his knees damn near almost buckled under him and caused him to quit his futile struggle. "Y'don't, agh...gotta do anything, man" The hedgehog winced "Ju-just lemme go and we act like it never happened! That's cool right?!"

"No way, Sonic. I need to teach you a lesson!" The echidna countered, and then a smirk grew upon his muzzle as his own phrasing surfaced a new idea in his mind. "Oh yeah, I'll teach you a lesson alright."

Sonic didn't like the sound of that, nor did he find the smirk or look in Knuckles' eyes to be of any sort of comfort. He closed his eyes and clenched his teeth with his hands balled up at his sides, just waiting for that fist to come flying into his face like he was sure it would. However, he let out a yelp in surprise when he found himself roughly yanked and pushed over something on his stomach. "Gah! What the!"

Knuckles decided not to punch Sonic. Instead he sat down atop of the stone stump where the pillar once stood proud and he yanked the blue hedgehog down over his lap! "You don't look so cocky now, do you?" He remarked as he saw the confused face of the blue hedgehog looking over his shoulder at him.  

"Knux... Dude! What the hell is this?!" Sonic struggled to get away, but the red brawler had both of his hands held firmly behind his back and too much movement put a painful strain on his arms. "Ow, argh-leggo man!" But despite the hurt he was nearly as stubborn as his furious rival, so he tried and gave a few hard jerks in attempt to break free but only ended up yowling in the pain it rewarded him.

"No, Sonic" Knuckles brought his free hand up to his mouth and clamped on the thick fabric of his mitt with his teeth, yanking the material off and discarding it on the ground. "If punching your lights out time and time again doesn't get you to learn, then maybe I'll have to try something else!"

At that, Sonic froze in shock and his muzzle turned a deep shade of red as he felt the now bare hand of Knuckles resting on his backside. "Oh no..." It was at this moment he fully realized his butt was up in the air on purpose, to be the prime target of the echidna's wrath in the form of something he had never had before... 

"Oh yes" Knuckles confirmed the hedgehog's fears by raising his hand up and bringing his open palm down harshly upon his left cheek with a loud smack! He didn't even give him time to plead him not to go through with it. Like it would help anyway, Knuckles instantly loved his newfound position of power over his blue rival and was going to make him know it.

"YOW!" Sonic yelled out the moment the strike connected and the sting made his butt clench, as well as his entire body tense! "AH! Dammit Knuckles, that really hurt!" He grit his teeth and his toes were curling in his sneakers from the sting radiating throughout a single cheek that was struck.

"That's the point!" Knuckles responded, also with an equally harsh smack of his hand to Sonic's right cheek! *SMACK!* It resounded throughout the wilderness and Sonic's ass jiggled due to the impact.

"GAH!" The hedgehog yelled out again, now feeling the same sting encompass his other cheek while the first one started to tingle. But the tingling didn't last for long when the echidna revisited it with what felt like an even more powerful strike "OOOWWWAH!" Sonic cried out, unable to keep the magnitude of the sting it caused to himself. Not only did this hurt, but Sonic was reeling from the sheer fact that it was happening. Never in a milion years did he ever think something so humiliating would befall him such as receiving a spanking from another guy.

Knuckles could tell that last one was quite painful and he had to snicker as it made Sonic go rigid like a plank over his lap. But he didn't stop there and let his raised hand fall on the right cheek again with a rivaling power!

"AGH! Owowow stop it STOP!" The blue hedgehog winced and whined with one eye partially opened, his muzzle red in embarrassment from being given such a treatment that he just wanted to end. But unfortunately for him, it didn't end. He yowled out again as another loud smack from Knuckles' palm spanked his ass so hard it made his teeth chatter!

Then came the onslaught from the echidna who was now enjoying himself while spanking and lecturing the hedgehog *SMACK!*  "Each pillar here!" *SMACK* "Has it's own special!" *SMACK*" Ancient engraving!" *SMACK!* "Telling a story!" *SMACK!* "Now that story is missing a piece!" *SMACK!* "BECAUSE OF YOU!" *SMACKSMACKSMACKSMACKSMACK!* He assaulted Sonic's rump without mercy, each blue cheek bouncing and starting to glow pink as he kept it up! "I'm going to make sure you fully regret ever coming to this spot to play your childish games!" His hand clapped harshly off of Sonic's pinkening then reddening rear end, making noise one off in the distance might even think was some kind of machine gun fire!

Sonic made a plethora of uncomfortable faces and noises each time the punishing hand of the echidna came raining down with fury on his ass, alternating from one cheek to the other. The pain of the sting radiating through him from the rapid succession of harsh slaps made him want to squirm and struggle free, but all he could do was pitifully kick his legs up and down behind him and cry out in agony as his spanking continued. "Ah! OW Chaos, URGH! Eno-enough!"

"It'll be enough when I say so!" Knuckles replied as he continued to spank the other and delighted in his reactions. Not only was it fulfilling to inflict this kind of pain on Sonic, but he loved how the punishment he was dishing out also humiliated him a great deal! At this point so far, his hand showed no signs of stopping the assault on that blue ass.

The open palm continued to pummel Sonic's propped up rear end, the sting growing rather warm and hot too as he squirmed and writhed as much as he could over Knuckles' lap. The echidna must have started putting some chaos energy into his assault, or smacking his ass so fast and hard his hand went aflame like his more powerful signature punches! The hedgehog's body was beading in sweat and his muzzle still painted red in embarrassment from the ordeal as he yelped and now even started to whine much louder. All of that squirming was doing him no good however, as he realized something  was now occurring to increase his humiliation ten fold. "Ah! N-no! You have to stop!" He cried out, hoping Knuckles would relent and let him go before he could notice that his sheath was swelling beneath him. 

Sonic couldn't help it for some reason, but something about the pain and warmth enveloping his two cheeks and perhaps the lewd act it'self, was beginning to make him grow aroused. "Knucklehead! Just cut it out! I-OW! NNGAH!" He tried to protest further, feeling his heart beating so hard with nervousness he could swear it had migrated to his throat. Never had he felt anxiety like this, always being cool and collected no matter the dire situation. But he had never been spanked by anyone before, especially not another guy and especially not Knuckles. He'd never even thought of it, and so here he was, in shock, dismay and fear. All he could do was squint and seethe drool, desperately trying to will himself from slipping out of his sheath. "Hhhhnnnnngggg!" 

But to further add to Sonic's dismay, Knuckles didn't stop. He spanked him harder and faster, seemingly lost in the addicting sight of watching his rival's once blue cheeks turn a bright crimson red that were seemingly starting to glow! "What did I say, Sonic?   I said that I get to decide when enough is enough!" The angry echidna delivered five more harsh slaps to the hedgehog's ass, but then abruptly stopped and blinked in confusion as he thought he felt something poking his inner thigh. "Wait a minute..."

Oh no, Sonic shivered and gulped as he lay over his red rival's lap. The sting and burn from his freshly spanked ass was now the last of his concerns when the punishment ended on the note of Knuckles clearly feeling his growing arousal prodding at his leg. "L-look, Knux I'm sorry alright? Now just let me go and I'll be off your island in the blink of an eye I promise!" He attempted to reason and tried to pull away, only to find the grip holding him still as firm as it was in the beginning.

Knuckles snorted and smacked Sonic across the ass again before smirking about the ordeal, because this was just one more way to add to his embarrassment. "Wow, Sonic, I never imagined you'd be the type to get off on being spanked" He teased to rub it in and make it worse.

Those words crashed through Sonic's ears like a tsunami of things he really clearly did not want to hear right now. "AH! What?!" The blue one peered over his shoulder with shocked eyes "I am not that type of Mobian!"

As soon as Sonic protested that, his head turned forward again and let out a curse as Knuckles smacked his sore ass yet another time! "Hah!" Knuckles laughed shortly when he felt his rival's cock very obviously swell in response against his leg. "You dirty liar" He shook his head, but soon looked Sonic over as he still kept him in the spanking position. 

"I'm not lying! I-I don't know why it's happening!" Sonic hollered, feeling tears stinging the corners of his eyes from the sting of his ass coupled closely with the humiliation of the whole situation. The blue hero had no idea Knuckles' eyes were now wandering over his stricken visage, taking and soaking in what a thrilling sight he had lying bent over his lap.

Sonic actually had a nice round shape to his ass, Knuckles suddenly thought to himself as he examined the damage done and was surprised to find it enticing. "I guess... I'll stop now" The echidna announced to the hedgehog, who was all too eager to be let go.

However, to Sonic's confusion Knuckles wasn't loosening his one handed grip. He didn't dare squirm though, knowing the act would only make his hard on more excited. "Y-ya gonna lemme go now?" The blue male asked in a weak and somewhat hoarse tone.

"Not yet" Came Knuckles' reply. The echidna was feeling his own sheath start to swell at new ideas swimming in his head, fueled by the fact he hadn't had a good lay or even took care of himself in quite some time, and right now Sonic's ass was looking quite appetizing.

"What?! But why not?!" Sonic yelled and uselessly kicked his legs up and down, unknowingly only making his reddened freshly spanked rump look all the more alluring as his two cheeks shifted from the movement. "You got your revenge! You spanked and humiliated me beyond comprehension! It's enough!" 

But it wasn't enough for Knuckles as he realized what a juicy ass he had literally in his lap, vulnerable and looking ever more delectable by the second. There was no verbal reply from the guardian and Sonic was made to wince when he felt the red one's hand land on his ass again, only this time not in the form of a punishing spank. No, Knuckles had seriously just pressed his hand fimrly to his right cheek and squeezed it, causing the sting to become an intense tingling sensation that made him shiver with a small whine escaping him. His muzzle reddened  even more as he felt the echidna commence to rubbing and kneading that freshly spanked cheek. "Knuc-knuckles what are you-aah!" The hedgehog let out a surprised gasp, shuddering when suddenly he was spread back there.

Knuckles only chuckled at the reaction when he parted the way and let two of his fingers graze over the pink hole hidden beneath Sonic's tail. "Are you aware of how hard your dick just pulsed against my leg, Sonic?" He asked, taking ample opportunity to embarrass his rival in yet another new way he himself found to be quite thrilling. 

"Shu-shutup!" Sonic stammered, feeling another tickling at his back door as Knuckles lightly moved his fingers over it again. This time he did realize how hard his member pulsed against the crimson mobian's legs "Da-dammit, Knuckleheadcutitout!" 

Still the echidna heeded no plead from the hedgehog, only chuckling now whilst he scooped his hand under Sonic's blue sack and cupped his balls with a gentle squeeze. "I don't think you really want me to stop" With that said, he conjured up a little spit and let it drip into the crevice of Sonic's ass for what he was planning next.

The hedgehog shivered more while his balls were groped and he felt the thick warm saliva seep between his cheeks, of course dripping over his hole therein. Then with Knuckles still cupping his balls in hand, the hedgehog felt his thumb slide up through the crack of his ass to greet his tight and now slickened  pucker, pressing and gliding around the pink area in circles. Oh sweet chaos this was beyond wrong, but why was this turning him on so much? Sonic trembled as he asked himself the question in his mind, feeling like he needed to get the hell out of the predicament while another part of him felt some kind of intoxicating thrill. "Don-don't" He pleaded again, only this time much weaker than any time he did before.

"See what I mean?" Knuckles asked condescendingly and pressed his thumb more firmly against the hedgehog's slippery hole. "That didn't sound very sincere to me, Sonic. And plus, I think I can feel something dripping over my thigh"

Sonic's ears pinned back almost submissively at this point. He realized his cock was more than raging hard, pressed against his crimson rival's lap while continuously throbbing, now leaking a discharge of glistening pre cum over the side of the brawler's thigh. The arousal was heightened as there was a slightly ticklish sensation from Knuckles just barely pushing the very tip of his thumb into the center of the tight ring beneath his small blue tail, which hiked up and twitched at the action. "Hnnnh"

"Oh, got nothing to say now, huh blue boy?" The echidna asked with a devious smirk, teasing the center of Sonic's tight asshole some more before going back to gliding around the rim of it in slow circular motions. "How about if I do ....this?"

After Knuckles' thumb made a few more trips around that most private area, Sonic felt the pressure against his hole return. Only this time the echidna wasn't just merely teasing him by prodding. Instead, he felt that pressure building in the center, slowly increasing and wedging him open for the penetration. "Ahhhhnnhh!" The blue hedgehog's body quivered with a gasp and moan, his back arching as the full digit of Knuckles' thumb breached him and sank deep within his ass. "Knu-Knuckles sto-sto-aahhh~" He attempted a protest, only to have it transition into a pleasured moan when the echidna went straight for the prize and rubbed something sensitive inside him. "Nnnnggghhh-ah" Sonic whined, blushing greatly but tried adding a "damn you" to put up a guise of not liking it. 

However, the stronger male could see through that futile attempt. "Hahah, just what I thought" Knuckles rolled and rubbed Sonic's balls in his fingers while making short back and forth motions with his thumb deep in his blue rival's ass. He licked his lips reveling at how snug, warm and nice that hole was, squeezing his intruding digit. The lewd act it'self was making him harder as well. "If you really wanted out of this, I know you'd give a more effective way of showing it. But all you're doing is whining and trembling with your cock on the verge of erupting all over my lap"

That had managed to strike a nerve in Sonic other than the ones consisting of his prostate. The hedgehog grit his teeth and let out a growl in response. "Fuck you" Sonic spat, trying to rally up his defiant side. 

But Knuckles had the perfect comeback as he pushed his thumb more firmly against that sensitive bundle of nerves, which elicited Sonic to arch his back with a louder whining moan. "It kind of sounds more like you want me to fuck you instead~" 

After Knuckles said that particular phrase with a spine chilling lustful growl attached, did it become apparent to Sonic that among the sensation of the thick thumb embedded in his still tingling ass, he could also feel Knuckles' long girthy cock poking into the side of his abdomen. At that his stomach developed what felt like a swarm of fluttering butterflies going crazy. "N-no... No I don't!" He claimed, although not able to sound very convincing from how worked up he was. In fact, his arousal level was steadily and quickly coming to a head as Knuckles continued to press, rub and massage his thumb into his prostate with growing vigor behind his ministrations.

"You better not make a mess on my lap, blue" The echidna warned without telling why as he worked his thumb around in Sonic's tight ass, pushing against velvety walls every so often before going back to attacking his main target. Oh how close he could tell the hedgehog was with the way his cock pulsed and leaked a growing discharge of pre cum.

"Ahhhng, aaahhhh, Knuc-Knuckles!" Sonic cried out with the pressure and pleasure building in his swelling dick, then a few more firm rubs of his prostate was what it took to bring about his body shuddering release. 

The echidna could tell for sure that this was the moment he made the his rival cum, for he felt that blue sack firming up in the palm of his hand while he thumb-fucked the blue hedgehog's hole which also tightened. However, he had other plans rather than just allowing Sonic to have his climax.

Sonic's eyes rolled and he moaned at the start of his orgasm. But before a single rope of cum could fire from his cock, he felt Knuckles' thigh pressing up against his rigid twitching member with force. "Wha? Ahhhhnnggah!" He cried out with the corners of his eyes tearing up, as Knuckles' new action compressed his cock slightly painfully between them, causing the stream of his jizz to slow down and dribble from the tip rather than shoot like normal.

In doing this, Knuckles was ensuring Sonic made a mess of his lap with his hot cum dripping over the side of his leg. He was also stifling his orgasm by cruel force just to leave Sonic in a more eager state of wanting, for the echidna still wasn't yet done with him. "What did I say about making a mess, Sonic?" He asked, sounding annoyed as he pulled his thumb free of the blue hero's ass with a slick noise. 

Sonic was quivering and sweating slightly as he laid limply over Knuckles' lap having just been thoroughly violated and denied a pleasurable orgasm. "It's your.... fault" He panted and stayed where he was. Perhaps it was because his mind was hazy or his arms were numb from being held crossed behind his back for so long, or maybe a combination of the two. But he didn't seem to realize the echidna had finally released his wrists at some point.

"I don't know what you're talking about" Knuckles played dumb and disregarded it. "But You know how we are, right?" He asked, putting the next phase of his plans into action.

"Wha... What do you mean?" Sonic inquired back with his ears slightly perked, not yet getting what Knuckles was driving at.

"You know, how we always have to one up each other all the time?" The echidna's devious smirk came into play again for what he was about to tell his poor spent rival. But he was oh so eager to, so he didn't waste time letting Sonic give another response. "You came on me, Sonic... So now I'm going to do you one better by cumming inside of you"

Sonic's eyes widened at hearing that and he tried to struggle, only to yelp when he found himself completely manhandled by Knuckles, the echidna suddenly and swiftly moving him to be on his knees at the pillar stump. "Knuckles no!" The hedgehog yelled out.

But Knuckles was set on his goal and made Sonic bend over the stump of stone with his rather juicy looking blue ass presented to him. "Yes, Sonic!" He licked his lips, getting up behind his rival to wedge his cock between blue cheeks like a hotdog in a bun, meanwhile he held the hedgehog down with one hand.  "What's the matter? Afraid you can't take it?" He taunted.

Sonic pinned his ears back and grabbed hold of the broken pillar,  gripping it for it was all he could do besides blush as Knuckles throbbing rod was felt between his blue buns. He erfed and whined while the echidna was grinding up and down betwixt his still tingling cheeks, lewdly lubing up the crevice with the pre cum that oozed and dripped from his tip. But the taunt coming from the crimson one pressed a certain button, one that practically obligated the blue hedgehog to prove his rival wrong. "Shut up and just do it! I-I can take anything you can dish out, Knucklehead!" He countered almost impulsively like he would to most of Knuckles' challenges. Only this time he regretted it when Knuckles shifted behind him and he got the sensation of his warm cock head slipping against his tail hole, painting the pink entry way with slick pre cum. He bit his lip while his heart rate increased. He wanted to take back what he said but it was too late now and there was no way he could back down as he felt growing pressure against his bud. 

"Damn, still really tight" Knuckles commented, not making it any easier on Sonic as the hedgehog just closed his eyes and grit his teeth for what was on the way. "Almost... aaannnd there~" The echidna said in a tone of satisfaction, watching the head of his cock finally pop in past the hedgehog's snug tail hole. "ooohhhh, damn... the heat~" He purred, shuddering while slowly pushing forward to find those velvet walls were still nice and open from thumb play to make way for his tool.

Sonic gasped and his eyes shot open when Knuckles' thick helmet penetretaed his ass, causing his back to arch and his breath to quicken as he could feel his hole stretch to accommodate the girth. "Ahhhhnngh, hhnnngggg why do you have to be so big?" He complained through grinding teeth, gripping the pillar stump tighter as Knuckles' cock sank further into his depths inch by inch until he would finally feel the other male's balls press flush against his taint.

"It sounds like you're about to give up" Knuckles commented on Sonic's whining while he remained sheathed completely in his blue rival's ass, even playfully bumping the base of his crotch against those round cheeks. 

"Ahhh! I am not!" The hedgehog boldly declared, wincing as that thick cock moved ever so slightly inside of him, and then soon began to pull back. "nnnnhh" He found it hard to stay silent when Knuckles pushed back in slowly after only retracting about four of his seven fat inches, then repeated.

"Mmmph, good so just take it like a champ" The guardian murred whilst slowly pumping in and out of the speedster, his hands now groping and kneading the blue pillows that took him deep inside. "Never knew what a sweet ass you had until now" He chuckled and angled his cock downward as he pushed himself in balls deep again.

Sonic blushed and was opening his mouth to make some kind of retort against that comment, but as he did Knuckles' member scraped over that spot where his thumb recently played and caused a heated moan to slip free. "Oooooohhhngghh~" The pleasure that surged through his ass and cock seemed much more intense than when the echidna was using his thumb. It jarred his senses and made him nearly achingly rigid all over again. He felt Knuckles' cock pull back and he braced himself to feel that intense pleasure again.... But it didn't come. His crimson rival was beginning to fuck him at a steady pace now and it seemed like he was purposely avoiding revisiting that spot.

Knuckles smirked because he could tell Sonic anticipated the moment he'd grind his dick against the bundle of nerves inside him another time, and he was such a bastard he wanted to make the hedgehog ask for it. It wasn't like hitting that target was detrimental to his own pleasure, he was quite content to thrust forward and back, aiming nowhere in particular as he enjoyed watching his thick length repeatedly disappear between those round blue ass cheeks. 

The hedgehog wasn't happy with it however. He could feel Knuckles fucking him and it was pleasurable to a degree, but he was desperate to be graced with those insurmountable waves of bliss that could be rolling through his body. "Hnnnnh, d-dammit" He cursed and bit his lip.

"Something wrong, Sonic?" Knuckles asked as if he didn't know while he still leisurely moved his hips back and forth, savoring how the hedgehog's ass squeezed his dick in it's warmth and his hole occasionally clenched around him. At this point the passage was slippery inside with his accumulated pre cum. He went in balls deep and stayed hilted there to wait for a reply.

Sonic groaned as his walls were stretched and Knuckles stopped moving with his crotch firmly pressed against his rump, squishing his blue cheeks. The tips of his ears heated up red like his muzzle as he thought about how to answer, meanwhile he could feel Knuckles' cock throbbing buried deep in his ass. "Nnngh, d-do that again..."

"Do what again?" The echidna asked, which made the hedgehog cringe because he really didn't want to say in detail.

"Th-that spot" Sonic replied, hoping he didn't sound as needy as what he felt. "Yo-you hit a spot" He gulped as he finally admitted "You hit a spot that felt... really good" 

"Oh you mean this spot?" Knuckles suddenly pulled his hips back and thrust forward hard with his cock at a downward angle to make a precise strike against Sonic's prostate.

"Ooohhwwahhhh! Aahhnh-yeah!" Sonic practically saw stars before his eyes when the intense pleasure shot through his nether region, and he had no time to prepare before Knuckles plowed into that zone yet again and again, his thrusts becoming faster and harder than what they were before. 

Knuckles grit his teeth and growled, taking it up several notches as he had enough of taking it easy on his rival beneath him.  He watched Sonic squirm and quiver, whining as he rammed his cock in and out of him. "You like being fucked huh?" He licked his lips and squeezed Sonic's ass with both hands, spreading his cheeks to watch himself piston through his tail hole. "Perhaps we should do this stuff more often~" He suggested, talking so he could get a couple words out between the loud slaps and claps his hips made from impacting Sonic's ass.

Now Sonic was in a pure and unbridled state of bliss. His body jerked forward and he let out loud whining moans as Knuckles slammed his long thick cock into him, hitting that sensitive area each and every time "Ahhnnngh aaahhhhh nnggh-yes, Oh chaos Knuckles!" His senses were being driven wild. The cock of his friend rapidly pumping in and out of him began to heat up his hole, adding yet another aspect of pleasure to it all that had his bobbing member leaking a steady discharge of pre cum.

"I hope you're ready for this, Sonic" Knuckles huffed and grunted, slapping Sonic's ass a few times while he rammed his dick into his depths even harder and faster still "I Grrr haven't nnngggh cum in, hah...aahh several weeks!" 

Sonic could barely even make out what Knuckles said from his head being so clouded in lust and pleasure. He was being fucked senseless and seemed to be loving everything about it as he whined and moaned, keeping his back arched and even trying to push back against some of Knuckles' deep thrusts. "Ahhhnh aaah oh ffuck, hhnnnnngggh mmmmmmmhhhhh~" His eyes rolled back to an incredible blissful feeling ripping through him like a lightning bolt, his body trembling as Knuckles quite literally fucked the cum out of him. "AH AHH OH CHAOOOOOOS!" He shouted as his dick surged and swelled, pulsing and firing long hot thick ropes of his hedgehog seed on the grass below him with such intensity he could barely stand it!

"Hah, aah, oh fffff-uck!" Knuckles felt Sonic's hole tighten around his cock in reflex to the hedgehog firing off his load. His ass seemed to be pulling him in and he didn't want to fight it as he pushed deep, sinking his entire swollen length and girth as far as he could into Sonic. His hips met flush with blue cheeks and he grunted with his orgasm hitting hard, making him quiver as he leaned over to put his weight on Sonic's back. His cock spasmed inside him with burst after burst of hot seed firing into his blue rival's cozy depths, making his ass even warmer and more pleasing as his own cum flooded around his dick in those tight confines.

Sonic was spent and limp as he laid over the stump of the pillar, breathing and blushing hard as he was being bred by Knuckles. "Hhnnnnhh" He slightly whined, panting as that rigid tool could be felt pulsating in his stretched and strained hole, a warmth building up to the brim of his ass to drip out down his blue taint and balls. Sweet Aurora, Knuckles was really pent up. His balls must have unloaded half a quart of hot jizz into his ravaged yet still tight ass. 

Knuckles was panting by the end of it, but not as much as Sonic was after he thoroughly fucked him. "Hah,hahh, damn~" He held the hedgehog by his hips and slowly withdrew his cock with a wet slick pop from his friend's well filled tail hole, smirking as he watched Sonic's tail twitch and his gaping hole leak a bit before closing up. A few extra shots fired from his dick, painting streaks up Sonic's back and over his ass. "Whoo! Now I feel better" The echidna beamed whilst giving the hedgehog's rear a few firm pats, then simply began to take his leave. "I'm gonna go cool off under the waterfall now. It's up to you if you wanna stay or leave. Just don't break anything else or I'll let Chaos in on the action next time"

Sonic just stayed where he was bent over the pillar stump, panting and shaking as he watched Knuckles walk away from the scene. How strange it was, he might actually have liked everything the hotheaded echidna just did to him, he thought to himself as he rolled off of the stone stump to land with his back in the grass. "Knucklehead..." The ravaged hedgehog muttered in frustration, his muzzle cheeks a rosy red as he felt the warm seed of the guardian slowly dribbling from his tail hole.
