The alternate Sonic drops in under a minute. He's bigger than the Sonic Shadow knows, so he'd expected more of a fight, but the reality is just sad.
He looks down at the blue hedgehog laid out on the ground and clicks his tongue. "And here I thought my Sonic was incompetent."
Sonic—or what passes for him in this universe—flushes. "I'm not incompetent," he hisses. "You just caught me unaware."
Shadow raises his eyebrows, unimpressed. "Is that so?"
Sonic climbs to his feet, nodding frantically. "Definitely. I'll prove it, too."
Shadow would much rather start figuring out a way to get back to his own universe—or at least the void, if his Sonic still hasn't managed to fix things—but he's unfortunately familiar enough with Sonic to know he's not going to get anything done while the blue blur is intent on bothering him. He sighs and shifts back into a fighting stance. "Go on, then. Show me what you've got."
What he's got, it turns out, isn't a lot; the fight barely lasts thirty seconds.
"Pathetic," Shadow spits. He starts to walk away.
"Where are you going?" Sonic asks.
Shadow looks back at him. He's pushed himself up from where he was lying facedown on the ground so he's sitting on his knees. His face is even more flushed than before, ears drooping. Shadow usually wouldn't even bother responding, but Sonic looks so damn pathetic he can't help himself. "To find a way home."
"I can help you," Sonic says, a little frantic.
Shadow scoffs.
"Seriously," Sonic insists. "You're in an unfamiliar place, right? I could show you around, help you look."
"No thanks," Shadow says. "You won't be of any use to me. I doubt you could even follow basic instructions."
Sonic's flush deepens even more. He hunches forwards, shoulders curling inwards. "I can."
Shadow crosses his arms over his chest, stares. Sonic uncurls, glares up at him from his place on the ground. "I'm serious. Give me an order, I'll follow it."
Shadow rolls his eyes. He doesn't have time for this. Luckily, he knows an order he can give that no Sonic would ever follow, so he can prove his point and make Sonic leave him alone in one fell swoop.
"You want to be ordered around so bad? Fine." He smirks. "Lick my shoe."
Sonic jolts. "What?"
"You heard me," Shadow says. He slides one leg forward, wiggles his foot a little. "Lick it. Unless you really are useless."
Sonic's ears tilt back, flush spreading all the way down his chest. His eyes narrow as he looks between Shadow's foot and face—and then he drops onto his hands and knees, crawls forward, and licks at the toe of Shadow's shoe.
Shadow stares, torn between shock and disgust. "What are you, a dog? Get the hell off me." He kicks; Sonic jerks away before he can hit him, rubbing at his mouth.
"You're the one who told me to do it," he mutters. "Make up your mind."
"I didn't think you actually would," Shadow says. "Just how pathetic are you?"
Sonic's mouth twists. "I'm not pathetic."
Shadow scoffs. "Clearly."
Sonic's hands ball into fists. "Do you have any idea how many people I've saved? I'm a hero."
Shadow thinks of his own Sonic, of how many times he's saved the world. He never brags about being a hero, or about saving people—he just does it. "If that were true," he says, "you wouldn't be going to such lengths to prove it to me."
He starts to walk away again, only to stop when Sonic's hand closes around his wrist, pulling him back. "I—"
Shadow whirls around with a snarl, shaking his grip off with laughable ease. "Didn't I tell you to get off? Do as your told."
Sonic shivers. He places his hands behind his back; when Shadow takes a step backwards, he shuffles forward on his knees.
Annoying. Shadow growls, tells him, "Stay."
It's more than a shiver this time; Sonic's entire body trembles. He groans and curls in on himself for a second before straightening up again. Shadow frowns in confusion, roams his gaze over the blue hedgehog's body to find out what that reaction is all about—
And freezes. Blinks. Rolls what he's seeing over in his mind, turns it this way and that. Smirks, finally, and says, "Good boy."
That gets him a moan, and the view of Sonic's cock pushing further out of its pouch. Unsurprisingly, it's proportionate with his body—which means it's huge compared to Shadow.
He can definitely work with that.
"Shadow," Sonic whines. He looks up at him, eyes wide and shining, ears tilted downwards in submission.
Shadow chuckles. "Fuck, you're easy. Do you get like this when your Shadow orders you around, too?"
Sonic shakes his head. "No, he's—" He laughs, the sound a little breathless. "He doesn't usually beat me. Honestly, he's kind of a joke."
"So everyone in this universe is like you?"
Sonic whines again at that, high in the back of his throat. His cock emerges further, a drop of precum beading at the tip. Like Shadow said: easy.
"I'm not—" He swallows thickly, shudders. "I'm still better than him. What does that say about you?"
Admittedly, the knowledge that some version of him is apparently incompetent enough to lose—repeatedly—to this Sonic is a little irksome—but in the end it doesn't matter. Why would he care about any copies of himself when they're bound to be inferior? And besides—
"You say that, but I bet you'd be just as happy to get on your knees for him if he ordered you to."
Sonic glances down at himself, eyes widening as if he's only just now realizing he's still on his knees. Shadow clicks his tongue at the sight. "Eyes on me."
Sonic snaps his gaze back up. His eyes are still wide, pupils blown.
Shadow bites back a smile. "Good. At least you were telling the truth when you said you could follow instructions."
"Yes," Sonic breathes, "I can—"
Shadow raises a hand. "Did I give you permission to speak?"
Sonic closes his mouth. Swallows. Slowly, hesitantly, shakes his head.
"There we go," Shadow says. "That's a good boy." Predictably, that makes Sonic moan again. His cock has emerged fully; Shadow takes a moment to admire it, its length and width. He waits until Sonic gets impatient enough to whine, then gives it a second longer before he says, "Come."
Sonic shuffles forward on his knees. He wobbles a little, unbalanced with his arms still crossed behind his back. Shadow watches him, lips curling in amusement. When he comes to a stop, Shadow reaches out to pet him; Sonic shudders at his touch, bowing forward like he's having trouble staying upright.
Perfect. Their height difference is such that he's too tall for Shadow's purposes even while on his knees; he presses down on Sonic's head, forces his back to bend further. Sonic makes an aborted sound like he was about to say something, then evidently thinks better of it and glances up past Shadow's arm instead, eyes wide in question.
Shadow sighs, playing up his disappointment. "Do I have to spell it out for you? Get on your hands and knees."
Sonic obeys, planting his hands on the ground. He tilts his head up so he can still look at Shadow's face, one of his ears flicking this way and that like he's waiting for another command. He's wearing an ugly bandana around his neck; with a little imagination, Shadow can almost pretend it's a collar.
"Good boy," he says again, chuckling at the sound Sonic makes in response. He steps closer, so his crotch is just in front of Sonic's face, spreads his legs a little, and says, "Now eat."
Sonic's eyes widen, surprise evident in every feature. "Whoa," he says, voice colored with something like wonder, "I had no idea you—"
Shadow grabs him roughly by the chin and forces his mouth closed. "Good puppies don't talk," he hisses.
Sonic whimpers, a pretty sound that almost makes Shadow change his mind about not letting him speak. Although he supposes it won't matter for much longer anyway—Sonic's mouth will be otherwise occupied soon enough.
He lets go of Sonic's chin—and this time Sonic doesn't hesitate, leaning forward to bury his face in Shadow's cunt. He's sloppy with it, laving his tongue through Shadow's folds and over his clit before dipping it into his hole. Even his tongue is big, stretching him more than one of Shadow's own fingers could. Spit dribbles down his chin and into the sand below.
It's far from the best head Shadow's ever gotten, but he supposes he can give points for enthusiasm. Sonic certainly seems to be enjoying himself, tail wagging so fast it's almost a blur.
"You really would get on your knees for just about anybody, huh? I mean," Shadow pets through Sonic's quills, tugs hard enough to make him groan, "look at how much you love it."
Sonic moans, the vibrations traveling through Shadow's clit like an electric shock. His legs tremble; he pulls Sonic closer against him, says, "Just like that. A little more, come on."
Another moan; Sonic sucks at Shadow's clit before shoving his tongue as far into his cunt as it will go, nose bumping into his clit instead. He's deep, certainly deeper than any tongue Shadow's had up there before. Shadow tightens his grip in Sonic's quills, keeps his head in place and moves against him, fucking himself on Sonic's tongue until he climaxes, cunt spasming around the muscle inside of him.
He stays where he is for another long moment, riding out the aftershocks, before he releases Sonic's head and steps away.
Sonic gasps as he's let go, pants hard enough that his shoulders shake with it. He looks a mess, muzzle wet with his own spit and Shadow's slick, dick hard enough that it almost seems painful, leaking so much precum that it's formed a wet spot in the sand below him.
"See? Look at how much you get off on being used like this," Shadow says.
Sonic follows his gaze, looks down at the wet spot in the sand. He groans at the sight; more precum leaks from his cock.
Shadow laughs. "Fuck. You're about ready to burst, aren't you?" He crouches in front of Sonic, tilts his head up with a finger under his chin so their eyes meet. "Do you wanna come, puppy? Answer me."
"Yes," Sonic blurts, "I want to come. Let me touch myself, Shadow. I—"
"No," Shadow says. The betrayed look on Sonic's face tears another bark of laughter from him. "You should see your face right now. You'll never try to argue you're not pathetic again."
Sonic's ears tilt back. "Are you—"
"Quiet," Shadow orders. He straightens up, stares down his nose at Sonic for a moment before saying, "Sit up. Hands behind your back."
He was half expecting this to be the moment when this Sonic finally grew a spine, but after only a second of hesitation he does as he's told. His cock juts up from between his legs, hard and weeping. Shadow had planned to make him wait a little longer, but it's hard to resist; he drops to his knees and straddles Sonic, drags the folds of his pussy up the length of his dick, adding his own slick to the mess already there.
Sonic moans; his head tips forwards but his eyes roll back, his shoulders shaking like he's having trouble keeping his arms behind his back.
Shadow smirks and lifts himself higher. Sonic bucks his hips up, nudges the head of his dick against Shadow's thigh before Shadow reaches out a hand to push him back down. He can feel Sonic straining beneath him, but it still barely takes any effort to keep him in place.
"Stay," Shadow orders. "Be a good boy and wait while I stretch myself."
Honestly, there's no real need for it; he's resilient, regenerates fast, even enjoys getting stretched beyond his limits now and then—but the miserable whimper Sonic lets out is more than worth it. Besides, he doesn't exactly trust that Sonic will last long enough to bring him to climax again. Better to get close, first.
Shadow keeps one hand on Sonic's hip to keep him in place, slides the other down his own abdomen slowly so he can watch Sonic track the movement with his eyes like a man possessed. He circles his fingers around his clit a few times, moans when it feels good just to hear Sonic whine in response, then finally sinks two fingers into himself with a sigh of contentment.
He takes it slow, leisurely scissors his fingers until he feels confident adding a third. Sonic strains harder against him, until Shadow actually has to work to keep his hips down. "Stop fighting," he snaps. "If you distract me, this will take that much longer."
Sonic groans, visibly fighting to stop bucking his hips up—but he manages eventually. Shadow rewards him by taking his hand off his hip to pet at his quills instead. Sonic's head tips forward, knocks into Shadow's shoulder—but Shadow can see his eyes are open, trained on where he's sinking a fourth finger into himself.
Shadow spreads his fingers, feels slick run down his hand. He's stretched enough for sure, but he keeps at it for a bit longer, curls his fingers inside of himself where it feels good, winds himself tighter until he feels like a rope about to snap—and only then does he remove them and wrap his hand around the base of Sonic's dick instead.
He holds it steady, rubs his clit over the head before settling it at his entrance. "Don't come before I do," he says, which is all the warning he gives before he starts to sink down on Sonic's cock.
As expected, the stretch is noticeable, would certainly be painful for anybody else. It's good—but it pales in comparison to getting to hear the noises Sonic lets out, desperate whines and moans that rise in pitch as Shadow sinks further down. He's long; it feels like it takes forever before Shadow bottoms out. By the time he does Sonic's voice is so high it's nearly inaudible, closer in frequency to a dog whistle than any form of speech.
"Good," Shadow says, rocking his hip backwards and forwards and feeling Sonic shift inside of him. "Now just hold on a little longer so I can finish."
He lifts himself, moans at the drag of Sonic's dick against his walls. Sonic's moaning, too, still, though it turns into a whine when Shadow drops down again.
Close, then—more so than Shadow had anticipated.
He huffs, reaches between them to rub and pinch at his clit even as he continues to move himself up and down Sonic's cock. He clenches, feels Sonic shudder, hears his moans rise in pitch again—right on the edge.
"You can't even last a minute?" Shadow sneers. "Pathetic."
That does it. Sonic whines as he comes, hot and wet inside Shadow. Shadow snarls and works himself faster. He doesn't pull away, even when he feels Sonic start to soften, hears him whimper in overstimulation—and then finally he tips over the edge too, fingers faltering on his clit as he works himself through it.
He stays seated on Sonic's dick for a minute longer, breathing hard as he comes down. Then he pulls off and stands up, wipes the cum he can feel trickling down his thighs on his glove, grimaces, then wipes the mess on Sonic's chest instead—after all, he's dirty enough already that it hardly makes a difference.
"Hey," Sonic mumbles in protest, but he doesn't make any move to wipe it off.
What a pushover.
Shadow looks at him, looks around, and starts to walk away.
"Wait," Sonic says, struggling to climb to his feet. "Where are you going?"
Shadow doesn't pause. "To find a way home."
Sonic finally manages to get up, runs after him until he's right behind him. "Don't you want my help?"
Shadow glances over his shoulder. Sonic looks disgusting, covered in semen, drool, and shadow's slick. His legs wobble with every step he takes, like a newborn fawn. Completely useless.
Shadow scoffs. "Absolutely not."
He powers up his air shoes and skates away, too fast for this lesser Sonic to follow.
