Chapter Text
There was something seriously wrong with him.
Sweat clinging to his skin, seeping through his cobalt fur and thrumming in time with his racing heart… that was the only feasible explanation Sonic could come up with, already teetering on his tenth orgasm. On a typical rut of his, he was out and finished by the fifth or sixth somewhere in the midpoint of his cycle, towards the end of the grueling two-week period.
Today was only his third day.
He should have felt satisfied and happily skipping through la-la-land by now, not overheated, overtaxed, and miserable.
If he were able to focus on anything but the skyrocketing lust boiling in his veins, he might’ve thought long and hard (no pun intended) about exactly why or how he ended up in such a predicament. Alas, he was exhausted, a little hungry, and still unbelievably horny.
He was over masturbating for the day—really, he’d been done hours ago. His dick on the other hand…
Sonic groaned, throwing a hand over his eyes before taking a deep, centering breath.
Just a few more. He didn’t know how much more, but a few—if only to wear out his stupid body and satiate his dumb hormones enough so he could finally get some rest. And then some food.
And… if he was feeling up to it, visit his brother and tactfully inquire why his rut would be so unbearable this time go ‘round. It would be a little embarrassing, but the blue blur honestly didn’t want to test how much he could stand before he became downright pitiful.
With that final lucid thought in mind, his dick found that to be enough thinking and not enough doing, twitching so hard it brushed his stomach.
Hesitantly, reluctantly as if it was the last thing he wanted to do, an ungloved hand trailed south once more, taking hold of his overly sensitive shaft, teeth pinned under his bottom lip.
Just a few more…
When Sonic came to, he had no clue how long he’d been out for. It appeared to be daytime, judging by the golden rays flooding his roddy thing of a shack, wildlife bustling outside, very much awake and alive. The next thing he noticed was a steady thump against the newly installed door, a familiar voice calling out from the other side.
“Faker, open up. I won’t say it again.”
In a rare moment of clarity, the speedster finds that he’s capable of doing so, stumbling off the hammock and to the entryway in a sleepy stupor rather than through a heated fog. Either way, neither could prepare him for the sight of none other than—
“Shadow?!” Sonic exclaimed, gobsmacked. “What – What are you doing here?”
The other hedgehog looked nonchalant, as if finding himself at Sonic’s doorstep was to be expected, yet with a tone that it definitely wasn’t. “Checking up on you.”
That halted Sonic in his tracks, waking him up completely. “Check – on me?” Cautiously, he leant slightly past the doorframe, eyes peeled for a hidden camera or perhaps any comedic chimps who weren’t above pulling an awful-timed prank during one’s rut.
Shadow sighed, “Believe me. I wouldn’t be here if I could help it either. However, your friends,” he spat as if the word was an unfamiliar flavor. “– have designated me as the only logical choice to examine your… condition.”
Despite the explanation, Sonic still couldn’t believe it, only able to stare like his mind had conjured some kind of nightmare to life. After all, Shadow was probably the last person he expected to see in rut—even Eggman was higher on the list, with his god-awful timing.
“Well… I have no idea how Amy managed to convince you, but you can tell the others I’m uh, doing fine. Just peachy, so…”
At this, the loner hedgehog gives him an even more unimpressed look than the one he came with.
“Have you looked at yourself?”
The near-accusation took Sonic aback, “What? No, there’re no mirrors in here – why are you even asking?”
A look up and down, “Because you look like shit.”
Perhaps any other day, Sonic would feel up to dealing with Shadow’s bullshit, maybe toss it back at him for the hell of it—but whilst his season that was already giving him trouble? As if. No thank you.
“Gee, thanks. You can go now.” Sonic dismisses, quickly yanking the door shut. When it stops in place instead, green eyes drop low, landing on a bulky skate hindering it from closing.
“Wait. I was given clear instructions upon coming here – and not even you are getting in the way of that.”
Somehow, Shadow manages to bully past him, letting himself in and closing the only barrier between them with a resounding click.
Sonic garbles as he’s shoved aside in his own home. “Shadow, dude! What the hell, man!”
But Shadow appears to not hear him at all, instead sweeping his gaze around and taking in the growing mess that was the hero’s living space—Meh Burger delivery wrappers, a pile of laundry in the corner despite him wearing nothing but a signature brown bandanna, and… a thin sheet thrown over some dubiously bulbous shapes that made Shadow decidedly not look any longer.
Despite himself, Sonic feels suddenly self-conscious of anyone, let alone his rival take in firsthand what the beginning of his rut entailed. Granted, he wasn’t the neatest guy per-se (his own brother could attest to that), but in this context felt a little too… personal. Intimate, even.
He doesn’t think even Amy has seen his quote-on-quote Alpha side, except for that one time…
“You’ve started early.”
The statement shocks Sonic from his trance. A statement, not a question. “Uh, yeah. Maybe a little – how’d you even know that?”
“Tails,” Shadow brushed off, seemingly unbothered with the information. “He informed me of the state you’d likely be in, as well as this sorry space for a den you have. Unfortunately for the both of us, he proved to be accurate.”
“Okay… not a den but, that still doesn’t explain why you’re here,” Sonic pressed, needing to understand why now, of all times the only other male hedgehog on the island was in his shack, miraculously of his own volition. Tails would have to come later, but this was something that needed to be addressed now.
He could count the number of times on one hand Shadow voluntarily chose to associate with Sonic, his friends, or anyone on the island really. He kept to himself; not unexpected behavior for an alpha, but for the average Mobian… it sure was extreme.
Sonic had to admit, whenever Shadow spouted the meeting again ‘on his own terms’ nonsense, he didn’t think it’d be at a time like this.
Attempting to recall such encounters must have been too much for his body to handle, as that was the last thought in his head before it became woozy once more. Clutching his skull, alarm bells went off thereafter, as Sonic quickly caught on to what was happening. How long had it been since his last session?
Shadow frowned. “Are you alright?”
“What do you think?” Sonic snaps, trying not to crumble under the next inevitable wave of his rut.
“Nevermind! Just – get out here, you can do whatever Tails sent you to do… later…”
This was bad. Being both Alphas, it was only a matter of time before sharp claws, teeth, and lethal punches were thrown.
It was simple biology; where one scent of a rut could possibly attract a mate—an Omega, specifically—the opposite would happen for two Alphas. From one to another, the scent dripping in pheromones worked almost as a deterrent, irritating and distressing enough for full blown fights to break out as a result.
Shadow and Sonic had their fair share of such, but never were they hormone-driven and thus, not deadly. At least, not as much as they could be with level heads.
With all this knowledge, Shadow makes no move to leave. Doesn’t even appear to be in discomfort, despite what Sonic without a doubt must be reeking of, if the rising warmth in his gut was anything to go by.
“Shadow. I’m serious, you gotta go man…”
“Has your rut been like this the whole time?”
Sonic was starting to breathe heavily, heartbeat picking up in pace. “Hah… What?”
“It looks painful,” Shadow continued, ignoring him. “Is it usually like this?”
It was harder and harder to think by the second, Sonic felt like he was using all his brainpower to answer Shadow’s onslaught of questions. “No… it… this hasn’t happened ‘til recently.” He doesn’t realize he’s no longer standing until he opens his eyes, seeing Shadow kneeling before him, his own back to the wall.
“I’ve had bad ruts before, but… this…” The heat in his loins takes that exact moment to flare up, making Sonic certain that, had he not already been on the ground, would have surely collapsed then and there.
Shadow’s head bobs in a nod, as if in understanding. “What have you been trying?”
Alright, of all the events leading up to this point, that catches Sonic off guard the most. “...What?”
Shadow rolls his eyes, as if the conversation they were having was nothing short of normal. “To alleviate the symptoms. I can see you have – ” his eyes flicker to the hammock, “tools. But what are your methods–”
“Whoa, whoa, whoa,” Sonic sputtered, “Are you… asking how I get off?” Sonic probably should have been offended in some way, but the situation is so utterly ridiculous he can’t help but laugh. “Sorry pal, we may be close but – not that close.”
He didn’t think they were close at all, actually. Despite them saving the world together once or twice. So why was Shadow acting like… this?
There was a scoff as Shadow stood without further preamble. “Fine, I was going to offer some advice on behalf of your brother, but if you’d like to burn up to death, then be my guest.”
Advice… what?
“Wait,” Sonic tries, before he can blip away. “What do you mean? You know how to fix this?”
“Before I can answer that, you need to answer my question first.”
Oh, great.
For a split second, Sonic thinks better of it, pride stifling his words and urging him to kick the other hedgehog out of his house already—but an embarrassing and untimely bulge threatens to rise, causing Sonic’s legs to hastily cross.
He did not want to pop one right in front of his rival in the middle of an argument, thank you very much.
“Ugh okay, fine! I… jack off like anyone else alright? And when it gets really bad I uh, use… other stuff.”
“Self-pleasure aids.”
“Weird way to say pocket-pussy man, but – yeah.”
“And that’s it?”
“Dude, what’s with you? Why all the questions?” How was any of this supposed to help?!
“If nothing else is working, why don’t you take a mate?”
Shadow asks as if it's the most logical thing in the world—and, Sonic supposed it technically was, but it certainly wasn’t that simple.
Between all the heroing, napping, and other random shenanigans he would get up to with his friends, there was simply no right time to settle down and court someone, let alone find one to tango with.
That had nothing to do with his crippling anxiety revolving around physical intimacy, of course. Nope, nuh-uh. Not a chance.
Besides, by the time his cycle was over with, he no longer felt a need for something as primitive as a mate. Really, this was the only time his Alpha instincts made itself present, every other aspect in his life was easygoing as far those standards went.
“...I don’t want one.” The Alpha finally settles on, realizing the other’s eyes still on him.
There’s not an immediate response from Shadow, which makes him feel a tad uneasy. The growing arousal had diminished significantly as well, Sonic supposed ruminating on deep-seated fears against one's will would kill the mood instantly, rut-induced or not.
“Then, why don’t you experiment with alternative kinds of stimuli?”
At this, Sonic just gives him a blank stare. He wished he could say he had an idea where this conversation was headed, but to his dismay, he hadn’t a clue. And that was what frightened him the most, more so than Shadow’s erratic behavior.
When Shadow doesn’t receive a response, he sighs, finally deciding to put Sonic out of his misery.
“I’m talking about penetration, hedgehog.”
Out of his misery and straight to hell, apparently. This was his own personal hell.
“No offense, but what do you think I’ve been doi – ”
“Anal penetration.”
That shuts Sonic up faster than a spring trap.
Of all things he could have possibly said...
The words take a moment to process, bouncing around in Sonic’s head before shattering along with the last working parts of his brain.
“Ex-Excuse me?!”
“It may take some trial and error, but it may prove to be effective given your current… state.”
Sonic was shocked speechless, a little grossed out, and a lot weirded out. Before he knows it, the bewilderment flashes into anger, as he dredges up the strength to lunge at the other, obviously catching Shadow off guard as he pins him to the ground, dark eyes staring up at him.
“Sonic – ”
“Get OUT.” Sonic growls, teeth bared in his face. “I’m warning you!” If this was some sick way of his to amuse himself—!
Shadow’s expression pinched, top lip curling in a snarl of his own before something he couldn’t explain flash in those onyx-colored eyes.
He can practically feel the rumble building in the hedgehog’s chest temper to a low thrum as he says, “This isn’t a joke, I’m being serious.”
“Oh yeah, and my fur is green – ”
“Won’t you just listen, you senseless blue fool?!” Shadow bellows, “I didn’t need to come all this way, but being the ultimate life form, I’ve come to take pity on you and your low-life cycle – ”
“Low-life?! News flash, you got one too you dumb jerk – !”
“The least you can do is be grateful!”
Shadow is no doubt using his Alpha tone, but it's the words that make Sonic nearly foam at the mouth.
Oh, god. Oh, god. Shadow was being serious, dead serious.
That, or Sonic had gone officially crazy. He was inclined to believe the latter.
A strange weakness came over him then, entrapping him so harshly he could do nothing but face Shadow, stunned. Never mind the fact he could feel his rising boner die with each word that passed.
In the midst of his thoughts, Shadow shoves him off, the hero landing with a soft ‘oof’ as his ass met the floor.
When he looks up, Shadow is at the door, his back to him. Just as Sonic thinks he is going to leave, he turns to look over his shoulder, meeting Sonic’s eyes so intensely a shiver runs up his spine.
“If you have any questions once you’ve got that head out of your ass, come find me.”
And just like that, in a gleam of light, Shadow was gone.
…Oh Yeah, Sonic had questions all right. Really, just the one:
What. The. Fuck.
“Shadow, Tails?! Seriously?!” Sonic threw his hands up in the air, almost as high as he raised his voice.
Thankfully, his brother had the sense to look guilty, ears folding and tails swishing in a dejected manner that almost made Sonic fold—almost. First, he needed answers. Then he could be a doting older sibling.
“I’m sorry, Sonic. Really. But I just… had a feeling. And I know you don’t like me being around at this time, so…”
“But Shadow?” Sonic groaned, “You could’ve asked Knuckles again, or literally anyone else… hold on, how did you know about, uh…” he trailed off, not able to bring himself to finish the thought.
The fox shrugged. “You’ve been complaining about your cycles getting worse recently, so I thought an early check-up wouldn’t hurt.”
…Sonic supposed he had been a little verbal with each end of his season, though to his recall it wasn’t excessive or anything. Tails was known to be detail oriented, so it was most likely that.
“I guess not… still have no idea why it’s been happening at all though.”
“Hmm… Could it be your diet?”
Sonic’s expression was a cross of unamused and deadpan. “Even if it was, and I bet it’s not – I’m not giving up my high-calorie low-nutrition fast food for anything!”
“Then, I’m fresh out of ideas,” Tails ribbed, rolling his eyes. “Seriously though, there’s no reason you should be complaining this much…”
“You’re telling me!” The hedgehog said, “I’m just glad I didn’t do anything embarrassing in front of Speedy McEdgehog… which, by the way, I know you were worried, but just – not him, okay?”
Sonic knew he was cutting the younger some huge slack, but was willing drop it for now and pick it up at a later date. Or he would have, if it weren’t for how fidgety his brother currently was: twin tails still curled, nearly squeezing between his legs, eyes averted with fingers twirling a stray wrench.
Green eyes squinted. “Tails, do you…?”
The fox jumps before his question is asked, making Sonic frown. “Tails – ”
“You said you weren’t feeling good right? Then, well, you need to get back to your shack before it um – starts and stuff!”
The younger was now pushing him towards the door, Sonic’s heels scraping the ground as he was being forced out the workshop. Before he could let another word out, Tails had already shut the door, shouting along the lines of finding a solution from the other side.
Sonic was more than slightly peeved at the younger’s behavior, more so than being forced out of his second home. If he didn’t know any better, he would have thought the fox was hiding something… however, he knew from experience how horrible he was at that. At least, when it came to between them.
Whatever, his brother had a point. Now that Tails mentioned it, he could feel another wave coming on and he probably should be headed back by now.
When he returned to his shack with Meh Burger bag in hand, he was equal parts surprised and intrigued at what looked a lot like a care package at his doorstep.
His initial instinct was that Tails had left it, or perhaps even Amy. However, the contents of the parcel threw those thoughts off completely; pain meds and snacks were a given, but a blanket? Scented candles and muscle rollers? Even a survival kit that was likely not from Sticks, as she had never given him actual tools before. Maybe a pile of throwing stones paired with a bundle of… well, sticks.
Deep down, Sonic had a feeling who could have left such a thing.
And he did not want to believe it.
A few days later…
This was awful. It had to be Sonic’s worst cycle yet.
The hero was pretty sure he was running a fever at this point, not like there was anything he could do about it at the moment. Thankfully, his piquing arousal had considerably died down. However, in its place brought a different breed of throbbing, the sort that caused his head to pound and clog the rest of his senses.
He needed to hydrate. Looking to his side, he made out a couple figures… water bottles, and only two left. Not good. He would just have to sleep this off for the time being, and then…
And then… what?
Wait for his next hour of suffering? Sonic would deny any and all masochist accusations with this time being no different, if only because this certainly wasn’t the good kind of suffering…
Through all the brain fog, wandering thoughts came and went. He could have very well dozed off a couple times, he wasn’t too sure. Intrusive notions and random memories alike swirled in his mind until fact and fiction soon became one and the same.
Lounging away in his hammock before a majestic sunset cast over an endless tranquil sea of blue… tracking down some kind of mind-control device before it could seize and possibly enslave anyone else on the island… an ex-badnik robot-turned-friend that Sonic definitely didn’t imagine enveloping him in his strong, steely arms…
The images changed gradually, shifting from less innocent and more… sensual in nature.
Another rut spike, it looked like. Time for Sonic to buckle up.
At this rate, it was either a headache or a boner, and right now the former was likely going to be the death of him.
There was no face in his fantasies, usually. Few would believe him, but no specific features would come to mind. He supposed it didn’t matter as much as the raw presence his mind conjured, an impalpable aura that needed no descriptors above the bust of some mystery Mobian. Perhaps that only added to the suspense.
What he did imagine however…
Were hands roaming his body, groping him in a wanting, bold manner. One that never failed to leave him hot and bothered before they trailed up his waist, a possessive lilt to them before reaching his neck and wrapping around it. Hard.
His fantasy escalated from there, quicker than usual—the grip tightening around his throat, not enough to crush his windpipe, but enough to leave him with a tingling feeling—really, it was moreso the thought rather than the act itself that Sonic found so hot. He, the speedy savior under pin and thumb of deft hands that knew exactly how to play with his body… possibly better than himself. It made him shudder.
After so many lonely ruts… someone else doing the work sounded quite appealing.
Traveling south, fingertips teased his weeping, aching cock; feather-light caresses brushing his shaft. Only a whisper of contact until Sonic was damn near begging for more than just a gentle caress.
Whoever it was, they would would have to be firm, strong, and a touch unforgiving. Much like the rest of his life, Sonic preferred a challenge, a push and pull. He wasn’t all about the flowery stuff, so surely that would extend to the bedroom…. er, bed.
Finally, after some blissful torture, would he be rewarded. The sweetest thrill granted after brief hardship.
Pumping him up and down, fast and rough like he did it himself. Even fondle his sac a little for ‘extra stimulation’ or whatever.
That mental image went on for a few moments before slowing gradually, at the crest of his peak, making him whine—but not for long, springing into action to grab hold of his thigh, flipping his body around thanks to the twin grip in his quills—onto his stomach.
From there, claws(?) trailed down his spine, his tailbone, then lower and lower… until they were below his tail—
Whoa, whoa, whoa. Wait.
Sonic’s eyes snapped open, heart slamming against his ribcage as he fought to control his rapid breathing.
What..? Was that…
‘Anal preparation, hedgehog.’ Shadow’s voice echoed against Sonic’s will, answering his unspoken question.
Yeah, unfortunately that was exactly what it looked like… Sonic couldn’t deny it if he tried. With all his remaining defenses down, he and his body were vulnerable in the throes of his merciless rut.
Very tentatively, Sonic closed his eyes, allowing his mind to lead him wherever it wanted, and the hands continued…
A grasp of his asscheek signaled the beginning of its excursion, sinking into pliant flesh and rubbing as if in a soothing manner for what was yet to come.
…Was he really about to do this? He was feeling desperate, sure, possibly more than he’d ever felt in his previous ruts. But what would the him three hours from now think? Then again, no one was here to see… it was just him. What was there to be ashamed of?
If it weren’t for Shadow of all people giving him pointers on getting his rocks off, Sonic would have felt differently towards this whole thing. Under less harrowing circumstances, he could say in theoretical confidence he’d have been open to the idea, but doing so now would literally be accepting help from the biggest pain in his side besides Eggman, incorrect Meh Burger orders, or even the Gogobas’ outrageous complaints.
Too bad for his lingering inhibitions, his mind wasn’t all that in control right now.
Now, his own hands moved in real time, circling the one part of him the sun didn’t shine with a single finger.
Sonic shuddered, but didn’t falter in his movements. Instead, he dug around for the bottle still ample with lube before he could talk himself out of it. Squeezing some on the same digit, he resumed his ministrations.
In his imagination, a frighteningly familiar deep voice worked him through it:
‘Relax,’ said the deep timber. ‘It’ll only hurt more if you don't.’
“’m trying…” Sonic mumbled aloud, eyes still closed.
Taking a deep breath, he released it slowly, at the same time carefully easing in a slicked finger.
‘There we go… easy.’
Sonic did his best to breathe evenly, leveling his anxieties with each release and sinking deeper and deeper inside himself.
He’d never done this before, so it felt a little strange. As an Alpha, it wasn’t exactly the most traditional way of relief, but in this day and age no longer was it looked down upon. Although, it was uncommon if not… unnecessary.
Good thing this island didn’t exactly follow the norm in a lot of ways.
As for Sonic, the new experience couldn’t help but add a sense exhilaration, a feeling familiar to him and so, he followed that guide until it ran hand in hand with the ebbing arousal.
His breath hitched, air caught in his throat as he brushed an overly sensitive area, similar to the surrounding tip of his ears or even his lower back. Not painful, simply… different. Brows furrowing, he crooked his fingers this way and that, blindly charting a map he couldn’t read. Times like these almost made him wish he was being led in some way, but maybe if he twisted his wrist just so…
“Mrgh,” He grit his teeth, instinctively clenching and that stung a bit—practically having to will himself to relax again before he could acknowledge… whatever that was.
Slowly, Sonic retracted himself, expelling a breath he didn’t know he’d been holding. Blinking blearily, he felt as though he was waking from a dream. Perhaps a weird one, but so far the experience was not nearly as painful as he was expecting. If it was due to the minuscule pleasure or outright distraction of a new frontier, Sonic didn’t know. But he definitely wasn't going to stop now.
Relaxing his muscles once more, he sunk back in, the intrusion coming noticeably easier than before, giving him the newfound confidence to explore further.
It definitely felt… odd, but not unwelcome. His dick hadn’t softened either, if that spoke for anything.
Speaking of his dick, he wondered what would happen if—
Hardly thinking anymore, Sonic shook his other hand of its death grip on the hammock and circle his erection instead. The action immediately had him panting at the added stimulation as his focus harshly shifted from one side of pleasure to the other, the unfamiliar impression of his stuffed ass to the very familiar feeling of his fist around himself.
His other end grew tighter the more pleasure he felt at his front—experimentally, he continued the motions tugging and pulling, nearly startling at the moan escaping his mouth when he found the precise rhythm—the drag as he tightened felt delicious this time around and at this rate, he would definitely bust at any second..
Eager hands needed no further motivation than that, growing a mind of their own to work himself to the end at a speed only the fastest thing alive could achieve.
‘You’re doing so well now,’ the voice returned, breaking through his consciousness. The phantom praise did wonders for Sonic’s growing need, chasing an end he didn’t realize was approaching until he was in the thick of it.
‘More… MORE. That’s it… come… for me.’
Sonic gasped, a pitiful sound escaping his mouth at the exact moment his seed shot, arcing in the air before settling onto his fur with barely a hush of sound.
Gross…
Gross, but oh so satisfying. Sonic’s ears rang blocking out any other possible noises, but he didn’t care. Sagging blissfully as he descended from his high.
‘Good job… Faker.’
Lids fluttering closed, he fell asleep.
