The vast majority of Shadow’s dreams are nightmares.
This isn’t a nightmare.
Someone asks him, “Are you comfortable?”
The details gain clarity quickly. Shadow’s wrists and ankles are tied to… wooden bedposts? They pop into existence the second he realizes they weren’t bound to anything previously, despite the fact that he couldn’t move. The ropes capturing his limbs are cobalt blue, he’s laid spread eagle on his back while someone gently tests his bindings. The bed he rests upon is comparable to one that would be in a cheap motel room, but nothing seems to exist beyond it- a void of nothingness that his mind refuses to comprehend. No walls, floor, or ceiling, and thinking about it makes his brain instantly blank.
He’s missing his gloves, socks, and shoes as well as his inhibitor rings, but that’s another thing he stops contemplating just as soon as he realizes it.
Shadow turns his head and sees a completely naked blue hedgehog, green eyed and with a tan furred muzzle, arms and stomach. He possesses two obsidian horns which sprout from his forehead, twirling like a kudu’s would, as well as a long, thin, spade tipped tail and a pair of leathery wings upon his back, both of which are the same abyssal color as his horns. Trying to ponder any of that for longer than a second makes Shadow’s mind feel full of static.
The stranger meets Shadow’s eyes and says, “You didn’t answer my question. Are you feelin’ okay? Need me to adjust anything?”
“No,” Shadow isn’t afraid for some reason, he has no idea why. His head is fuzzy, he can’t think straight. “What’s happening?”
“You’re dreaming, and I’m gonna show you a good time like something straight out of a… y’know, a dream. Relax and I’ll take care of you.”
The pressure of the ropes is turning Shadow on, as is the vulnerability- this feels natural, despite how abruptly he was dropped into this scenario. He mumbles, “Okay,” and his hips twitch upward involuntarily when a fully erect, knotted cock appears on the strange hedgehog’s pelvis like it was always there. He doesn’t question it (or rather, the second he tries to, he finds himself incapable).
“You can call me Sonic,” says “Sonic”, walking to the side of the bed (Shadow tries to wonder what Sonic is standing on and the thought disappears like it was never there). He places a hand upon his hip and gestures with the other as he talks. “You’re cute. All wide eyed and confused, huh? Don’t worry. I’m in your head,” he taps his temple for emphasis, “and I know all the things you want, what you like, what you’re embarrassed about and wanna try anyways. All you need to do is feel it.”
Shadow gains enough of his wits to ask, “What are you?”
Sonic chuckles. “Sharp one, ain’tcha? Don’t think about that,” the second he says that, Shadow stops thinking about it. “All I want you to think about is how good it’ll feel when I fill you up over, and over, and over ‘til you’re stuffed.”
A tiny hitched breath crawls its way out of Shadow’s throat at the same time his blood speeds southbound. Sonic smirks and says, “Yeah, focus on that, baby.”
Are his eyes greener than they were before? Shadow can’t scrounge up enough of his mind to figure it out, but he tries regardless.
“You gotta stop thinking,” Sonic crawls on the bed and looms above Shadow, caging him between his arms. “Guess I need to up my game.”
He gives Shadow a peck on the tip of his nose and sits back between his widely spread legs, the thick shaft resting (and twitching, wow) upon the soft fur just above Shadow’s hidden slit. When he stares and says nothing, Sonic asks, “Hedgehog got your tongue?”
Shadow replies, “You’re an idiot,” but he can’t stop looking away from the cock sitting just above where he’d like it to be. He tugs on the ropes binding his wrists and finds no give whatsoever, the pulses of arousal he gains from this knowledge will surely make him wet in no time.
“Feisty. I like that,” Sonic grins and instead of getting right to the action, he scoots backwards and lowers himself to the sheets. “Let’s see what you’ve got for me.”
Does this guy ever shut up? Maybe if his mouth is occupied. Shadow doesn’t try to comment, thumbs are spreading his fur apart to reveal his pussy. He feels his ears flick back and he bites his lip, his eyes going half lidded as Sonic inspects him. He knows what the strange hedgehog will find: greyish black skin that fades into a shockingly bright purple interior and an oversized clit that features a line of pointy bumps along its underside. That’s not to mention the rows of semi-flexible, short fleshy spines in place of a normal labia. He’s not as worried about it as he normally would be.
“You’re different, huh?” is all Sonic has to say about Shadow’s extraterrestrial bits and pieces. “I wonder how you taste.”
“Bitter,” Shadow says shortly. The first woman he’d ever been with had refused to continue going down on him after she’d sampled his unique flavor profile. No one has gone down on him since, he hasn’t allowed it. “You won’t like it.”
“I don’t knock stuff ‘til I try it, and I know you wanna have your cock sucked,” he’s right but Shadow isn’t saying that aloud, “So why don’t you chill out and let yourself feel it?”
“Maybe I would if you’d shut your trap and get to it already,” Shadow says, annoyed despite the fact that he’s horny and struggling with coherent thoughts. “If you’re in my head and you know what I like, you’d know I don’t appreciate waiting.”
This statement makes Sonic’s irritating smirk grow twice as large for some reason. His spade tail flicks behind him, lazy and confident. “As you wish, Shadow.”
The strange hedgehog places a gentle kiss on the hood of Shadow’s clit, which doesn’t really feel like much. Shadow raises a brow, unimpressed (he hasn’t given Sonic time to impress him, but he’d like to convey his disappointment anyways). He feels his own face betray him and twist into something far less uninterested when Sonic’s tongue flicks out, teasing the bumpy underside of his clit.
That doesn’t feel like nothing- it feels like so much it almost burns.
Sonic does it again, slow and steady, and again, and again until Shadow’s carefully controlled breaths hitch. Each lazy drag sends heat down Shadow’s spine, and as much as he’d like to pretend this teasing isn’t affecting him, he’s incapable of perfect nonchalance. He tries his best not to react, he fails when Sonic grabs one of his thighs and squeezes.
Sonic’s other hand sneaks up and very, very gently pulls on one of the spines, Shadow feels it twitch under his grip. He fights the sound he almost makes and gets it under control, by some miracle. He can’t stop the way his hips jerk, though, unfortunately for him.
It should take longer than it does but it’s right, and easy, and somehow he continuously feels like his blood is rushing out of his head and concentrating lower. His thighs tense, his wrists and ankles pull against the ropes. His fur only keeps getting wetter, from Sonic’s saliva and Shadow’s own slick. He doesn’t know how he keeps getting more turned on, but he’s not able to question it.
He wants Sonic to hurry up, but he bites his lip and takes what he’s given. He can handle the pace, and he doesn’t want to beg and give this obnoxious horned hedgehog (why does he have horns again?) another reason to smirk.
“Didja forget I know what you’re thinking? It won’t kill you to say please,” Sonic lets his lips brush Shadow’s skin when he talks. His breath is warm (it’s distracting). It's irritating that he stopped, and it’ll damage Shadow’s pride to ask for more, which is the important part. Sonic questions, “Is your ego really more important than feeling good?”
Shadow doesn’t reply verbally, but he thinks yes as hard as he can. Sonic huffs a laugh through his nose and says, “I can tease you all night, y’know, I don’t have places to be.”
“Do what you want,” Shadow attempts to sound bored and succeeds, even though he knows his facade is pointless against a creature that’s invaded his brain somehow. Speaking of, what exactly is Sonic?
As soon as Shadow tries to work out that mystery, Sonic takes his clit between his lips and sucks without much pressure, tongue sliding against the bumps. His pointer finger and thumb pull on a labial spine. Most partners don’t bother with those, Sonic seems to know exactly how to play with them. Shadow’s voicebox chooses that moment to fail him and he hums a short, undeniably pleased, “Mm!”
Luckily for Shadow, Sonic doesn’t stop to say something about it, but he oozes a disgustingly smug aura. Shadow ignores it, wishing his bizarre bedmate wasn’t so frustrating. He’s taking what he’s getting, but he isn’t completely happy about it. No matter if it feels great, Sonic kind of sucks (his skills with his mouth are irrelevant).
Sonic puts another pause on things to speak again, will he ever stop talking? “My personality is stellar, thanks a lot, but you don’t have to like it as long as I can get you off,” and he returns to tonguing and teasing Shadow’s clit like he never stopped.
“I think it could use some wo-,” a harder suck and tug shuts Shadow up fast, he clamps his mouth closed when the hand attending to his unusual outer anatomy discovers his inner anatomy.
Sonic slips a finger inside him and, to his credit, does not react except to flick his tongue against Shadow’s clit slightly faster. Someone once described him as feeling “like seaweed on the inside, dude” and the comparison stuck with Shadow, how could he forget that? Alongside “you taste like bitrex”. And “why are you purple”. And “why is your clit like that”, and-
All those past experiences flee Shadow’s head in an instant. He’s sort of aware it’s due to Sonic, but he’s more focused on the sudden static in his mind (which is also probably because of Sonic, but he’s having a real hard time comprehending that). Instead, the only thing he’s thinking about is Sonic’s promise to fill him up. Over and over.
Until he’s stuffed.
Shadow shivers, Sonic presses another finger inside. He curls them up, stretches them out, and loops that motion, playing with Shadow’s g-spot in just the right way. It’s annoying how easily Sonic pushes his buttons, how he knows the exact techniques Shadow uses to get himself off.
It’s not just annoying, though, it’s amazing. Why is Sonic here, in Shadow’s head? He can’t understand and is struggling to continue wondering why.
The idea is gone in seconds.
Shadow breathes through his nose, fully aware that he’s going to start getting noisy and he won’t have a single ounce of control over it. The second he opens his mouth, he’s going to moan or whine or make some kind of embarrassing sound, like an alien chirp or click.
There’s another rush of fuzziness in his head. What was he thinking about?
His unusual body doesn’t matter. His vocalizations don’t matter. His uncontrollable reactions don’t matter. Not a minute ago, Shadow cared about all that, and he doesn’t remember why he did.
Are Sonic’s eyes glowing?
He can’t think about it.
There’s a pressurized heat building in his stomach, pulsing in his clit with every suck and lick, throbbing in his pussy with each press of skilled fingers. Shadow gasps and yanks on his bindings, his hips pushing up into Sonic’s mouth. He can’t move, he likes that he can’t move, he can’t think, he likes that he can’t think, and he’s going to cum surprisingly fast.
Shadow’s throat clicks like a geiger counter (a reaction he usually tries to avoid at all costs) and he digs his dulled claws into his palms, the waves of pleasure coming faster and hotter until he’s squirming against the ropes and-
What’s that sound? Oh, that’s him, starting to whine under his breath like a dog as his legs shake and his quills flare against the bedding. His toes curl and he feels his labial spines flexing against the fingers inside him, as if they’re trying to bite Sonic’s digits. He’s close, when did he get so close?
He squeezes his eyes shut, shouts and finishes so hard he feels something in his lower back twinge. The sensation is quickly washed away by everything else, the orgasm lasting longer than it should as Shadow writhes and whimpers through each shock of feeling.
Sonic’s fingers cease movement and his mouth leaves, but only when Shadow feels like he might pass out from overwhelm. Blinking down at the hedgehog(?) between his legs, Shadow has nothing left in his mind but fuck me, breed me, I need you.
Was there something he was concerned about? Does it matter?
Sonic grins wide (his chin is messy, his horns, wings and tail appear to have gained faint, glowing patterns like cresting waves). He says, “There you go, good boy. You took a while, but you’re there now, aren’t you?”
Shadow moans quietly in reply. He doesn’t know what Sonic is talking about and he doesn’t give a shit, he just wants the hedgehog (is he a hedgehog, who cares) to fulfill his promise. He pushes his hips up in a wordless plea, Sonic’s eyes flicking down as he does so.
“I’ll give you what you want. Yeesh, even when you’re totally out of it, you’re demanding. Not that I dislike that,” Sonic sits up and shuffles forward, his cock bobs with his movements. It’s thick, it’s long, it’s the only thing Shadow wants. “Most people break pretty quick, you should be proud of yourself for holding out so long,” Shadow shivers, Sonic smirks. “Yeah, aren’t you proud of yourself?”
Shadow whispers, “Yes,” but he has no idea what he’s agreeing to. His eyes are fixed below Sonic’s belt, he clenches on nothing and says plaintively, “Please.”
“Guess you’re not so proud anymore,” Sonic chuckles to himself and leans down to line up, one hand gripping his cock and the other bracing him against the bed. He presses the tapered head to the tip of Shadow’s clit and mumbles, “Gotta make the dicks kiss.”
Baffled and immediately taken out of the mood, Shadow says, “What the hell? Just fuck me,” and his mind is immediately wiped yet again. He doesn’t recall whatever Sonic just said or his reaction to it, only that he’s seconds away from getting what he wants. When Sonic grinds against his clit, Shadow’s throat starts clicking again and his ears pin to his head.
“I think you’re ready. Are you?” Sonic asks, like it isn’t obvious. Somewhere in the very back of Shadow’s consciousness, he knows he’s only being asked because Sonic wants to hear him say please.
He says it- correction, he whines it.
“That’s a good boy,” it’s spoken condescendingly and it makes Shadow squirm. He takes quick breaths in through his nose as the very tip pushes past his spines and presses inside, slow and steady. Sonic says, “Oh, that’s nice, you’re- oh wow. Huh.”
Shadow doesn’t question the reaction, he’s fighting the ropes and clicking up a storm as Sonic gently thrusts deeper, until he’s seated to the knot. Not all the way in yet, and he’s just thick enough to stretch without being painful. He leans over Shadow, close enough to kiss, and yet he doesn’t- why doesn’t he? One hand slides up Shadow’s side to tease his chest, blunted nails scratching under his fur.
It’s good, it feels really good.
“I’ve fucked a lotta holes,” that’s terrible phrasing but Shadow doesn’t have enough focus to comment on it, “and no one has felt- mm- like you,” Sonic sighs, pulling back and pushing forward with a squelch. “You feel incredible. Those pokey parts on the outside are- hnn, they drag just right.”
“It’s my labia, dumbass,” Shadow gasps, and his backtalk is rewarded with another full brain wipe. He shuts his eyes as Sonic begins a languid pace, unable to handle meeting the intense, luminous stare of his odd partner. Instead of giving Sonic lip, his clicking grows in volume.
“You’re like a radiation detector but for, uh, feeling good,” Sonic says, which somehow doesn’t kill the mood. Miraculously. “It’s kinda cute.”
Somehow that also does not kill the mood. Shadow rocks his hips down with what little leverage he has, letting the knot smush against his spines. His eyes flutter open in time to see Sonic’s brows crease, his breath audibly tripping. Somehow that’s more rewarding than the “good boys” were, witnessing the effect Shadow is having on him.
“Are you kidding? Of course you’re having an effect on me. Lots of effects,” Sonic says, and Shadow is inclined to believe him (no he isn’t). “You feel outta this world.”
Shadow exhales the tiniest laugh, and Sonic knows why because of course he does, saying, “Because you’re literally outta this world, Shadow.”
The hand on Shadow’s chest reaches up to cup his muzzle, and Sonic finally kisses him- deep and slow to match the meeting of their hips. Chest to chest like this, Shadow feels Sonic’s every motion, the tempo of his breathing, the beat of his heart.
This does some kind of emotional damage, Shadow isn’t sure what kind exactly. It’s tender in a way that hurts, something he feels like he needs but doesn’t get enough of. It’s uncomfortable and yet he wants it with every fiber of his being. Does it matter who or what Sonic is if he can make Shadow feel like this?
Sonic’s hand trails lower again, Shadow mumbles his name in between kisses. The not-hedgehog/whatever he is leans back enough to sneak his hand between them, rubbing his thumb against the hood of Shadow’s clit.
He isn’t sure which he wants more, to be kissed or to be touched. This feels amazing though, the back and forth movement on his sensitive skin. Shadow groans deep in his throat and his vision unfocuses, he senses Sonic’s cock twitch inside him and his groan becomes a little squeaky. He’s not concentrated on the stupid noise, he’s watching Sonic’s expression waver and his spade tipped tail flick faster.
Is he going to…?
Yeah, he’s finishing already. Shadow is unimpressed, despite how amazing everything felt. Sonic’s cock twitches four distinct times, and Shadow expects him to slow down, go soft and pull out- as per what most people with penises do.
Naturally, he has more than a few noises to make about it when Sonic does the opposite of what he anticipated. The bastard laughs at Shadow’s sudden, gasping moans and says, “Did you forget? We’re not just going,” a much harder thrust causes Shadow to release a particularly high pitched series of clicks, “once. We’re going until you’re dripping and you finally stop thinking.”
Straining against the ropes, Shadow gets one intelligible word out: “Fuck,” to which Sonic replies, “Yep, haha,” as he switches from rubbing Shadow’s clit to rolling it between his thumb and forefinger. He pays special attention to the nubs along its underside, and Shadow feels like he’s on fire- burning up from the inside out, his body overtaken by pure pleasure and nothing else.
Somewhere in the back of his head, he finds the loud, wet sounds created by their coupling disgusting, but it’s hard to linger on that. Through bleary eyes he watches Sonic’s face pinch and his eyes glimmer, the wavelike patterns on his partner’s non-hedgehog features pulsing in time with each movement.
Non-hedgehog features?
In a sudden moment of clarity Shadow realizes: He’s an incubus. The corners of Sonic’s mouth twitch up and he says, “Bingo, you’re sharp. We can’t be having that, though,” and within a blink Shadow no longer remembers the very important fact that just occurred to him. Instead, he’s writhing and clenching down on the cock inside him as he climbs towards another orgasm.
His mouth feels dry from all his open mouthed panting, his wrists and ankles are slightly sore and a muscle in his lower back is complaining, but-
If there is a seventh heaven, Shadow has reached it. His minor physical woes are scarcely noticeable, not when most of his body is consumed by ecstasy, not when his brain is almost completely blank and all he can think is yes, please, harder, faster, keep going. Sonic obeys his wordless commands and fucks him just like he wants, precise and perfect, sliding against his g-spot with every thrust in.
Sonic moans, “Shadow, you feel so- ngh,” and finishes again, but he doesn’t stop for even the briefest of moments- like each orgasm gives him strength or something. A miniscule part of Shadow feels like that’s significant, the vast majority of him is lighting up with fireworks. Filling him up, giving him what he wants.
Sonic pinches his clit, Shadow whines, “Ah- ah, yes!” and breaks the ropes holding his right wrist, his now freed hand scrambling to grip the arm Sonic is using to hold himself up. Ears flat to his head, Shadow pleads, “K-Kiss me,” and his partner lets go of his clit and does so without a second’s hesitation. Even without the external stimulation, everything is so much and amazing and overwhelming, he’s probably going to cum again just as fast as Sonic did.
Shadow’s hand slides up to grip Sonic’s quills and pull him closer, like he’s trying to make them one. His labial spines flex, he feels them moving without his control, how they shudder when Sonic licks into his mouth and deepens the kiss. He doesn’t care that they’re strange and alien, and especially not when Sonic draws back just enough to say, “They feel awesome, Shadow, I ha- haven’t ever felt anything like ‘em.”
Shadow moans in response, he wants Sonic to kiss him again and his wish is granted. The push and pull of their lips stutters when Shadow gasps and clicks, but stopping is the last thing he desires and he could cry with the sheer amount of sensation he’s feeling. If his eyes get watery, so what?
It’s not like Sonic cares.
Shadow grasps at Sonic’s back and hangs on, a second orgasm overtaking him the very second the knot pushes hard against his pussy. He wants it, it’s the only thing in his mind as he’s dissolved by pleasure.
As the peak fades, it all becomes a little too much in a way that’s different but just as good as it was before- if Shadow felt like he was on fire before, now he’s being immolated. Somehow he knows that Sonic will knot him and that won’t be the end, he has no idea how he knows that, only that he needs it with every fiber of his being.
He’s barely able to keep up with the kiss. Sonic backs off and his fingers return to Shadow’s clit, it’s an inferno on his oversensitive nerve endings and it causes him to shout an expletive. Sonic groans, “C’mon, Shadow, gimme one more and I’ll knot you like you want, yeah? Are you gonna be a good boy for me and cum again?”
Shadow whimpers, “Y-Yes,” because he is and it’s barely going to take three minutes. The pulling on his clit, the stimulation on his g-spot, his fuzz addled brain and his (mostly) bound limbs will do him in faster than he’s ever cum before. He clings to Sonic and moans so loud his throat strains, each breathy sound he releases underlaid by desperate clicking.
He’s done in by Sonic’s fingers rapidly stroking the nubs on the underside of his clit. His third orgasm takes out what little was left of his brain cells, the rush turns him entirely mindless. Reduced to a single desire: knot, please, knot me, I need it, Shadow doesn’t realize he’s begging aloud. His pleading is cut off by the next rough push against his labial spines, and all he can cry out is, “Sonic, please!”
Sonic gives him what he’s whining for, shoving his thick knot past Shadow’s entrance and pumping him full of even more cum, somehow. Shadow’s sigh is one of deep relief, pleasure and pain, as the knot forces him apart and keeps him locked in place- even moreso than the ropes.
His free hand flops limp against the bed, he blinks tears from his eyes and tries to catch his breath. Shadow’s entire body is buzzing, his back kinda hurts, and he has to swallow several times to make his mouth feel less like a desert.
It’s the best he’s ever felt in his entire life.
He may not be able to sense the cum inside him, but he knows it’s there and the knowledge is enough to light even more overstimulating sparks of arousal in his gut. Sonic mutters something absolutely incomprehensible as the glow fades from his lidded eyes and the patterns disappear from his odd features. Shadow doesn’t ask him what he said, he’s too focused on the knot inside him to speak.
“I was saying we’re still not done,” Sonic says, giving Shadow’s clit a brief rub (he gasps). “As soon as you’re ready, I’m gonna keep filling you up ‘til you can see it,” he places his hand on Shadow’s lower stomach, “and I’ve bred you so many times that everyone knows I’ve made you mine.”
Shadow nods dumbly and shudders. Sonic says, “Good,” and cracks a grin. “You’re fun. I’m definitely visiting you again.”
Is that supposed to mean something?
Whatever, Shadow feels too good to care.
