Sonic really had it all. He was known all over, had plenty of notoriety and had a good partner in the form of Tails the fox. Both adults now, the yellow furred vulpine made a relatively simple life for himself, going into the technology field, mostly staying at home but always enjoying his boyfriend’s company. Sonic had remained the same, being just as much of a free spirit and eager to adventure in his adult life while Tails was more content to hang back and be more of a support that would lend the hedgehog a gadget if it was needed. Discovering that he liked other males and becoming more of a homebody, the fox grew up and developed to have a more feminine body shape. He was slender in all the right places while also having thick thighs that caught plenty of attention, especially when he was wearing either shorts or stockings. He provided plenty of eye candy and Sonic was obviously proud to strut his partner about, admiring all the jealous looks they got. 

One of these jealous people was none other than Shadow the Hedgehog. As the others had, he grew up and became more mature but still had many of his old traits. Though he tried not to let it show or would ever admit it out loud, the black and red hedgehog had grown rather jealous of the blue one. But it wasn’t because of all the fame and attention the other one got, it was solely because of the one on his arm. Shadow had his eyes on Tails and wanted him. Shadow felt that he was more deserving of the fox and taking him would really put himself above the blue blur in yet another way. But Tails was very loyal, known to turn down those that approached and flirted with him, offering to give him what Sonic supposedly couldn’t. But unlike the rest of them, Shadow knew he would have the means to back up his words…

When he heard that Sonic could be away on a trip for a while, the dark furred hedgehog decided to finally make his move. Upon making sure that Sonic was indeed gone, he walked right up to Tail’s place. It was easy to find considering he lived in a house in the shape of his own head. When he was ready, Shadow gave the door a few firm knocks and then waited. It was only a short wait before the door opened to reveal the fox. He opened the door and Shadow was able to get a look at him up close. Even while standing there, Tails managed to be so alluring, wearing skin tight clothing that would naturally highlight his assets. 

“Oh, Shadow? What are you doing here-” Tails was caught completely off guard by the hedgehog’s approach, being grabbed by his ankles and pushed inside of the living room, closing the door with his foot. 

“What are you doing?!” Tails exclaimed when he was released. 

“Sonic doesn’t deserve you,” Shadow said firmly, stating his point right from the start. 

“Oh, not this again…” the fox groaned. “I’ve already told everyone else that Sonic is the only one for me and I’m not going to change my mind.” 

“Not even more for me? The one that’s better than Sonic in every way?” Shadow asked as he stepped forwards. It was only for a moment but he noticed that Tail’s expression did falter. “I remember when you were asked to choose between us. I bet you’ve been wondering if you’ve made the right choice since then.” 

“No, I haven’t,” Tails proclaimed. “And...even if I was, what makes you so sure you could be better for me than Sonic?” 

“Like I said, I’m better in every way. Not just in terms of power but I would take care of you, be by your side, instead of running off and leaving you alone all the time,” Shadow pointed out. 

“Sonic knows I can handle myself,” Tails insisted. 

“You know that if you were on my arm, all those guys wouldn’t dare make any kind of move on you,” Shadow said. “And you would be much too satisfied to be having any second thoughts like you are now.” 

“I’m not having-” Tails found himself completely frozen when Shadow grabbed his wrist, his hand was moved and placed on the hedgehog’s crotch and what Tails felt made him freeze up. 

“Like I said, I’m better in every way,” Shadow repeated with added meaning this time. This time Tails didn’t have a rebuttal. “Want me to show you?” 

Despite his better judgment, Tails couldn’t help but nod, his natural curiosity getting him to do something that knew was crossing a line. But what he felt beneath Shadow’s pants… There was no way it could actually be real. It had to be some kind of trick using the chaos emeralds…

But Shadow started to pull his pants down just as his length reached full mast. Tails gasped aloud when the waistband was pulled down enough for it to spring free and upwards. What Tails laid eyes on was a monster of a cock, just over twelve inches and amazingly fat. Tails couldn’t take his eyes off of it, even getting down onto his knees and reaching his hands out before he realized. Just one of them wasn’t enough to fully wrap around the girth. He had to use both and felt how strong the pulses were already. Pulling the foreskin back exposed the bulbous cocktip. 

“Did you forget that I’m also the ultimate lifeform?” Shadow asked with obvious pride in his voice. 

“It...it’s huge,” Tails marveled as he started to slowly stroke the shaft. 

“And you can have it all if you become mine,” Shadow offered. 

A part of Tails knew that it was wrong to just abandon his boyfriend over something like this, but this kind of cock was something incredible, even bigger than the largest toys in his collection. The idea of getting to interact with an actual cock, made of rigid throbbing flesh...it was just too much for him to resist. His body was pulsing as a whole, his mouth watering and his own cock pulsing in his shorts so hard that he felt he might cum just from gazing upon and holding the hedgehog’s rod…

“Okay… I’ll be your boyfriend, Shadow,” Tails relented. 

“Good,” Shadow grinned. “Now, you can get your fill.” 

After gazing upon the cock, Tails’ eyes drifted down to also look at the balls that hung underneath. Like the shaft, they were big and heavy looking. Easing his muzzle close to them, the vulpine’s sensitive nose was able to pick up on Shadow’s masculine scent and it was making him shiver with a sense of desire that Sonic hadn’t gotten out of him since their first time. Pushing his muzzle against the sack, he used the fur of his face to stroke them as he nuzzled, feeling the heat from the orbs transferring to his face. Hearing Shadow’s hum of pleasure, the fox pulled back just a bit so that he could start licking the balls instead, deciding that he was going to explore the sack with his tongue. 
Running his tongue along smoothly, he could really feel how big the balls were and how they were already churning. He guessed that Shadow was actually pretty pent up, making him sensitive to the touches. Or maybe the hedgehog was just that excited to finally have the fox. Either way Tails was becoming more excited himself, keeping his tongue moving as he went from one orb to the other, getting them both wet and warm from his saliva. 

Standing tall, Shadow watched as the fox serviced his balls, eagerly lapping at them in a way that was making his whole body tingle. He could really feel how much Tails was wanting this, his actions carrying a sense of passion with them. The licking was slowly increasing in speed and covering more area. The fox’s smooth tongue movements were coaxing more moans out of Shadow. His cock was starting to throb over Tails’ head but his focus remained on the pair of balls. He was swirling all over each and both at the same time, making sure to give them the same amount of attention. 

The gentle, smooth sweeps that went up and down or back and forth...the soft lips that could make a seal so that he could gently suckle on them, Tails was doing more and more as he became more comfortable and accepting that Shadow would be his new long term partner. The fox could feel himself falling in love with the dark furred hedgehog in real time and becoming all too aroused for him. He was moaning as well while working his mouth, giving the ball in his mouth plenty of licks and small sucks before pulling himself off, panting softly from the rush that was overtaking him. 

“Is that all?” Shadow asked. 

“Oh, I’m just getting started,” Tails said, speaking in a tone that made Shadow’s cock throb all the harder. Tails felt that as his hands were on the shaft again. He started to jerk it, pulling the foreskin along, moving down towards the lower half until that was the only portion he was touching. As for the upper half of the huge cock, Tails put his mouth back to work. He started to lick at the tip, gently caressing the fat end, making sure the whole thing was covered in his saliva, pulling back the foreskin and grinding his tongue against the extra sensitive glans, a move that had Shadow gasping. 

Tails wasn’t just attractive, but he was experienced, knowing just how to pleasure another man. It was much better than Shadow was expecting, making him all the more grateful to have the fox paired up with him. As the movements of his tongue were speeding like before and he started to kiss the tip, planting gentle pecks with his soft lips...Tails’ hands were stroking the lower half with more speed and squeezing a bit tighter, providing dual sensations that kept Shadow groaning. 

A new taste and something in his mouth made him pause. Blinking, he realized that it was precum but much thicker and richer in flavor than what Sonic gave off. Instantly wanting more, he kept up his licks to get as much as he could, humming in response to it. The more he interacted with Shadow’s length, the more of it he wanted. Already he got to the point where he was ready to take the risk of opening his mouth wide so that he could get the tip past his lips. Slowly he eased it in and continued to push, being glad he had so much practice with his big toys. Shadow was very impressed by what he was doing and how he was managing, feeling the warmth and wetness gradually covering his inches, one after another. 

Having the perfect chance, Shadow reached down for his lowered pants, fishing his phone from the pocket. Opening the camera app he held his phone high once it was recording. “Hey, Faker! You see this? Your fox is mine now, got it? Don’t worry, I’m already taking good care of him,” Shadow spoke as he and Tails were in frame, getting a full view of his huge length and Tails stuffing it past his lips. The fox was too focused on the task to feel any shame about having his cheating recorded. He managed to fit about half of the length into his mouth before bobbing his head back and forth, having it smoothly sailing over the throbbing pole of flesh, gulping down more of the rich precum that was leaking out. Shadow lowered his phone and watched the playback before smirking and pressing the ‘send’ button, of course sending it to the blue hedgehog. He almost wished that he could see Sonic’s reaction but he was also dealing with something more important. 

Shadow’s hand came down, applying pressure to the back of Tails’ head, “helping” the fox get even more of his inches in. Not content with just about half of his cock being serviced, Shadow slowly got Tail’s muzzle to spread wider, groaning as he felt more sliding over the smooth tongue, the tip starting to poke into the throat. He gave a small push that breached the soft tunnel. Keeping up the pressure, with his hips and hand, he was making Tails’ gag around his entering cock. But the fox was wanting just as much, grateful for Shadow’s help, even if the means of it happening was somewhat uncomfortable. As more entered his throat the passage itself started to expand against the thickness, the pulsing being felt directly against his walls. 

“Good boy…” Shadow said, looking down at the submissive vulpine trying his best to handle it all. He grunted from the next throb of his cock, releasing more precum that slathered Tail’s oral walls in his plentiful and viscous precum. Tails was still able to swallow the stuff. Swallowing and getting the precum smeared all over his throat’s interior was actually helping things along, the substance’s slippery state getting the cock in deeper with less effort on both their parts. 

Shadow seized the chance to shove his cock down, managing to get it all in, having his crotch pressed to the wide-eyed fox’s snout. Tails just let out a hard gag from the sudden hard intrusion, grateful for the precum giving him some leeway. 

“That’s it! Now take it!” Shadow said as he moved Tails’ head back and forth, making it slide back and forth along his length. Tails kept up his licking and sucking, giving his full oral attention to the huge meat, feeling his head pounding so hard in his chest. Panting and moaning against it, he willingly took on the challenge, letting himself gag against it but loving the way it stuffed his lower throat; it’s heat and strong pulses. Swallowing more precum was pulling the heat down into his stomach, giving him further comfort that was making his own length throb and leak within his shorts. 

Shadow had begun recording again, getting a full view but also having the phone pick up on the sounds of Tails’ throat being used and showing how much he was loving it. The thick wet noises of the precum-lubed muzzle being fucked, along with Shadow’s grunts would also be seen and heard by Sonic. The very idea was making Shadow all the more excited. Tails’ throat was repeatedly bulging, his snout bouncing off the other male’s crotch, almost slipping into a daze as he was able to take it without any trouble. The throat fucking continued and Tails began to lose track of time, not knowing if it had been 5 minutes, 10 minutes, or even more. Eventually he was snapped out of it when Shadow tugged his cock free, it being slathered in both drool and precum, still having yet to cum. 

Shadow took control of the situation, all but ripping the clothes from Tails’ body and groping his big ass aggressively. The hedgehog was pleased to find that Tails’ hole was already plugged. He pulled the toy free and traced his fingers along the stretched rim, feeling that it was already lubed inside as well. 

“Let’s see how much you can really handle,” Shadow said as he got them both down to the floor, lying on his back while Tails was in position to ride the hedgehog. Shadow’s hips guided the fox in position, sliding his tip in between the plump cheeks, just a moment away from penetration. 

“Y-you’ll be gentle with me, right?” Tails said with some worry in his voice. “You’re even bigger than my toys.” 

“No,” Shadow responded curtly and firmly. Tails didn’t protest but still braced himself for what was going to come next. 

Shadow pulled him down, making his hole spread even further around the girth, pressing firmly against the fox’s tender anal walls. The lube already inside of him and the fluids slathering the whole of Shadow’s cock thankfully made the insertion smoother than he expected. But he was still feeling instantly full, groaning from the strain his insides were put through. Slowly he regained his senses and was able to start going up and down as Shadow’s hands guided him, easing off to leave him doing it without  help. 

Tails had to take it upon himself to start riding the huge cock, gradually getting himself to take more of the shaft, lowering his body towards the hedgehog’s crotch. He was still getting used to the length that was reaching so deep and the thickness that was pressing down on even tender spot that he had along the way, stimulating even more as he was all the closer to the crotch, until he was sitting in the hedgehog’s lap, grinding against it and feeling the engorged rod throbbing inside of him. He was moaning out fully. This was something completely new for him and he couldn’t get enough of it. Having to keep his limits in mind, Tails rose up and then started to push his way down, panting from the thickness grinding against his walls the whole way. 

At the same time, Shadow was panting from the tightness that hugged whatever inches they were covering, the fox pushing himself down deep, taking the tip down into his depths that were squeezing even tighter, milking out even more of his portent precum. Tails was admittedly doing a good job but it still wasn’t enough to satisfy the ultimate lifeform. He wanted to truly breed his new partner!

He changed things up by getting hold of Tails and rolling them both over, switching the positions entirely. Tails was on his back with Shadow still inside of him. Now on top, having the fox in the missionary position, Shadow used leverage to slam his cock down into Tails’ ass, making him cry out in a way he hadn’t before. Just like that, Tails was seeing stars and his whole world was rocked by Shadow’s dick and how effectively he could dominate. Everything was so spontaneous and pleasurable, the huge thing plowing its way through his ass in brisk, hard, and merciless pumps. Shadow was powering his way in, sliding his shaft against the tight, hot and slick walls that were clenching firmly around him as well. 

With all of the control now on Shadow’s end, Tails was at the other male’s mercy, looking up at the hedgehog’s dominant, focused gaze. His intentions were clear and Tails felt something shift inside of him, embracing it all with the want to be used in this way, to be claimed by the hyper hung male, feeling it reaching in deep enough to make his stomach bulge a bit and the fat balls would come swinging in just after, smacking hard against his ass with repeated sharp ‘clap’ sounds. 

Showing that he was just getting started, Shadow started to speed up his thrusts, deepening his grunts in time with every pump, powering through every clench, further marking his new boyfriend with his precum from far inside. 

“How does it feel?” Shadow asked him, keeping his eyes on the moaning fox. Tails was just enduring everything that was thrown his way but he was doing so with a smile. Shadow was pushing him past limits he never knew he had. He tried to respond but the pleasure was just so overwhelming, making him either pant or moan in time with every thrust and smack of their bodies connecting. 

Even without being touched, his cock was throbbing and leaking so much, stimulated by the almighty pounding his prostate was receiving. Shadow just kept it up without any signs of slowing or getting tired himself. They all came hard, keeping the sensations at full strength and his body reacting with shakes and jolts. 

“He’s never made you feel like this, has he?” Shadow asked, referring to Sonic. Not expecting an answer, Shadow put even more force behind his thrusts, slamming himself in all the harder, making Tails’ ass clap all the harder. Tails had no idea how he was enduring all of this but he was...and loving every second of it. He loved how rough Shadow was, how he took control and kept things so exciting. When he was with Sonic things had become so samey. The blue hedgehog liked the same things, not wanting much deviation, but with Shadow, Tails had already experienced so much in a short amount of time. 

It became too much for him, making him cum entirely hands free. And he was cumming hard too, his twitching cock shooting ropes all over himself and Shadow as well as he continued to thrust, marking their chests and stomachs in sticky and hot ropes that clung to their yellow and black pelts. A smile spread across his face from the rush of euphoria that overtook him, still being fucked so roughly by the hedgehog’s throbbing erection. 

Even while the fox was cumming, Shadow was rocking his hips hard, watching with great satisfaction as the fox kept shooting his loads, watching Tails releasing it all over himself and then feeling the added tightness of his clenching hole. 

“Get ready for it!” Shadow told him, feeling the stronger throbs of his length. Going even harder, he moved his hips with greater vigor, showing himself off to be this unstoppable beast, fucking Tails like a monster that just wanted more and more. Like Tails, he was also experienced but so far the fox was the best at handling his cock and was giving him the most pleasure in return, still handling him at his full strength. 

Keeping it up, Shadow had his phone in hand and was recording this as well, making sure to capture the look on Tails’ face, the rolling of his eyes and how much he was shaking while covered in his own cum. Shadow wanted to make sure that it was all getting recorded, that Sonic would have plenty of material for himself while on vacation. 

“Faster! Fuck me, Shadow!” Tails pleaded when he finally found his voice. It just kept getting better and better. Having Tails’ plea recorded was the icing on top of the cake. It also goaded him into doing just that; pushing harder to penetrate the fox’s depths, getting Tails to cry out even louder, him clutching at the flooring to keep himself steady against the onslaught. 

Grunting through his clenched teeth, Shadow began fucking Tails with everything he had. The two were groaning out together, sharing the rising pleasure, letting their voices be heard within and outside of the house. The growls, moans, slaps of their bodies connecting over and over again, along with the deep slurps of the cock slipping out from the precum-soaked depths. This continued until Shadow finally reached his limit. He slammed his way in a final time and kept his cock lodged in deep while feeling the rush of his orgasm, every throb of his cock and big gush of cum that were firing out from his fat balls. Tails his guts getting quickly filled with so much hot and thick seed, to the point that his stomach was starting to inflate some as the pulses continued. 

Sighing deeply when it was over, Shadow was completely satisfied when he gazed upon the aftermath of all this, feeling the cum leaking out while his cock was still plugging the hole. When he pulled out it all came rushing out and pooling out onto the floor. While catching his breath, Tails knew that he wouldn’t be the same ever again and Shadow was just glad to finally have his perfect partner and he wouldn’t let anyone get in between them…

At first Sonic had been much too busy enjoying himself to notice his phone repeatedly buzzing. But at the end of the day he finally checked it and all the messages, looking upon them with wide eyes and an instant erection, unable to look away from the images and videos that showed Shadow stealing away his boyfriend, plowing him with such a huge dick. Sonic knew he should have been hurt by this but more than anything else...he was feeling jealous of the fox…
