It had been a difficult battle, but in the end, the Guardian Unit of the Nations was able to persevere against the planned invasion of the final faction of the Black Arms. With the new Black Comet destroyed, and the soldiers sufficiently debriefed, Shadow the Hedgehog was left with something he hardly finds himself with--free time.
"You are distracted," E-123 Omega said as Shadow sparred with the badnik.
"Since when were you concerned about my state of mind?" Shadow asks, performing a spin kick.
Omega blocks it with his wrist. "It affects your battle performance, and, most importantly, your destructive capability. Weak fleshlings like yourself need to speak their mind to run at full efficiency."
Shadow lands on his feet and grumbles. "Whatever, I'll figure myself out. See you later. If Rouge comes looking for me, tell her I'm going to let off some steam."
"I do not know nor care what you mean by that."
"Good."
Shadow left the training gym and made his way to the showers. While in there, he reflected upon the mission. They had been horrible alien monstrosities, to be sure, but Eclipse wanted to be a family. It made him think about things. He pulled his shoes off, letting them fall to the floor. They gave him a boost, hiding his real, shorter height.
Some ultimate life form. He can't even be proud of his stature.
He thought he had thrown his pride in his physical self away long ago, turning towards life as a protector of the human race, but not for any one's wish other than his own... but if he was engineered to be perfect in every way, then why was he shorter than Sonic?
He turned the shower on, letting the water run down over his quills and get the grime of work off of him. Sonic, such a cocky and arrogant hedgehog, but he doesn't have a care in the world. Such a smug... arrogant... inspiring figure. Why does he vex Shadow so?
Shadow's eyes flutter open just a bit as he leans forward, a hand upon the wall. He had felt it, certainly... his stress, his pent up thoughts, all building up in him, his frustration, his arousal.
"Fuck..." he breathes, seeing the length poking up from between his legs. "Here...? Now...?"
He looks over his shoulder. No one else was in here. It's not like other soldiers didn't let off some steam on their own, but him? Here? What does it matter? He's here by himself. He might as well do something about it. "S... stupid..." He grumbles, fingers curling against the tile of the wall as he wraps his other palm around his cock. His thumb plays at the underside of the head, rubbing up and down just underneath the opening.
"So... so damn annoying..." he grumbles, squeezing his eyes shut, rubbing one out, his fingers sticking with the water's friction.
"Fuck it." He sighs, grabbing the soap from the shelf and working it up to a furious lather. He presses his back up against the wall and slides down, his feet losing hold from the suds forming on the floor. Soon enough, he is on the ground, back on the wall, his spine curved a bit down below, legs spread. Now totally sudsy, he grabs onto himself again, letting the slip of the soap guide his hand as he slides his palm up over that shaft.
He stares downward, watching himself, his tail slapping against the floor as he got himself into a little rhythm.
He's a weapon
A hero
A legend
A monster
An alien
A role model.
He has to be all these things--all the struggles in life that others have, he has to bear a thousand fold, just because he was made to be perfect. But he's not perfect. He wants to be able to make mistakes and not be called out. He wants to have a life where his dumb sense of duty doesn't get in his way. He wants to be able to slow down--to explore not only the world but himself.
Explore...
Through a hazy gaze, he lifts up his free hand and lets the water run all the soap off of it. He then takes a deep breath and brings his middle finger up to his lips, wrapping them around the digit and then letting his tongue lather it up with spit. He scoots out of the way of the spray, kicking his way across with his heels until he's off to a dry section of the shower room. He takes that free finger, and he reaches down, curling it in and letting it poke at the hole beneath his tail.
He gasps, arching his back, spreading his legs and letting that finger wriggle its way inside. He groans, shifting around, digging his heels into the floor to allow himself to reach further inside. "F... fuck..." he sighs as the hole puckers around his digit. He curls it, playing with the cavity, swirling his finger, exploring himself.
His cock becomes harder than any jack off session could make him, but he doesn't want to end this... not yet, not quite like this. No, he has to savor every moment he has here alone and enjoy just being a living being and not the ultimate living thing.
He starts to imagine something... through the haze of lust, there stands a figure--Mobian in stature, looming over him. He chuckles. "Ready for some action?" he asks, his cock twitching in excited readiness.
"Sure, spread-em," the voice responds, grabbing his legs. Between the figure's own is a long, strong cock.
And shadow gasps, pulling his finger out from himself and scrambling up to a stand. His ass still burned from the sharp removal, but he didn't care.
"What the hell...?," he whispered. "Am I...?"
Before he could figure out the meaning of his fantasy, the doors to the showers open, leaving Shadow no time.

Water sprays through the deathly-quiet lockerroom. None of the people inside make a single peep, despite the strange sight within. For a good solid minute, a trio of Spider Troupe soldiers stare at the black-and-red hedgehog sitting on the ground, back against the wall, legs spread, and cock standing fully at attention.

Shadow breathes heavily, his eyes half-lidded, looking up to the humans who had insulted him on their previous mission and whom he had rescued, despite all that. He tried to play cool in front of them whenever he could, but this time--this private alone time in the shower--the Ultimate Lifeform can't let that veneer get in the way of what he's really feeling.

Shadow is the first to move, pushing himself up to a hunched-over stand, letting the water run down between his spines and push down his chest fluff. His lips curl up into a smirk, and he whispers. "You want some of this...?"

Captain Andrews is the first to respond. He drops his towel and steps up, looking down to the short hedgehog, his large cock dangling down in front of Shadow's face. "Well, now, what's this? Didn't think you were that kind of freak."

 Shadow wraps his fingers around the man's length, staring the head of the cock down as he slowly lets his palm stroke the smooth skin. "You made a lot of assumptions before getting to know me," Shadow says. "Alien... traitor... monster..."

With each of those words, Shadow's stroking got faster, pumping the captain's shaft with a furious beating off. "I had to save your stupid life for you to see me as anything but a liability--a tool!"
"Oh, fuck, Captain...!" Mantle says. "We seriously doing this?"

"What's the matter?" Clayton adds, tossing his own towel away. "You never done it with one of these shorties before?"
"What? No, of course not. I'd fuckin' break a girl in half shoving it up her pussy! With a guy, damn... he'd rip apart."

Clayton stands to the side, and Shadow grabs this second soldier's cock, pumping it as well. "And you," Shadow growls. "Always playing pranks back at base. Never giving me a moment's peace."
"Mmm, someone's mad," Clayton chuckles. "Go on, work on some of that aggression, you little slut."

 "Yes... a slut" Shadow says, turning his gaze towards the final soldier... "This is who I am. Why don't you join your friends, Mantle?"

Mantle shakes his shit. "Aw shit, here we go again," he says, letting the towel drop.
Shadow's eyes widen at the sight of the magnum dong, and Mantle shakes his head. "Yeah, yeah, I know. Black guy has the big dick. But if we're gonna go full-on porno, might as well go balls deep."

He steps up to Shadow, holding up the member. It's sheer size making it droop. He drops it, letting go and letting it flop onto Shadow's forehead. "Don't think I"m not a gentleman, though. Ain't no way this is getting in you without getting nice and lubed first."

Shadow grumbles, his nose rubbing on the warm, thick meat before he pulls his face back, letting the cock slide down. He catches it in his lips, kissing the tip before sliding it down into his mouth.
"Mmm yeah, look at him go. I wonder if its that alien stuff in him, makes him so good at this?" Clayton chuckles. "Or maybe the Mobians are just all horny little fuckers?"

 Shadow squeezes his dick and shoots him a glare.
"Hey, man, that's not cool," Mantle says. "He's a soldier just like the rest of us. He ain't no xeno scum, he proved that much today." He moves his hands to Shadow's cheeks, holding him a moment before finding a perfect handle with his quills. He squeezes them and thrusts forward.

Shadow coughs as the cock hits him in the back of the throat, now finding himself in the thick of it all. His own member oozes with pre from the attention and stimulation and from the groans of the three men pleasured by him. There's a serenity to the attention he's getting, and in increasing the happiness around him.
Mantle groans, his eyes catching Shadow as the hedgehog bobs along his dong. It's too much, and the soldier shoots off into him, filling Shadow's cheeks to bursting until his dick ejects, sending more jizz down Shadow's chin and chest.

Clayton, seeing this lewd display, can't hold himself back, and he gushes, shooting off against Shadow's face, making the hedgehog close his eye to keep from getting cum in it.
Shadow collapses, coughing up some cum from his mouth, shaking for a moment with the three men standing dumbfounded.
"Geeze, I think we went a bit overboard," Mantle says.
Clayton adds, "Commander's gonna be pii-ised."

 Shadow rubs his chin and, sitting on his knees, he lifts up his butt, his tail wagging as he presents his rear towards Andrews. "We're not done here, Captain..."

"Damn..." Mantle breathes under his breath.
"Little guy just doesn't quit, does he?" pants Clayton.
Captain Andrews, meanwhile, stands transfixed, staring down at the presented hedgehog ass, kneeling on the ground before him. Wordlessly, he lowers himself down, grabbing those cheeks and spreading them apart. With his expert aim, he spits right on ultimate asshole and then presses a thumb at that orifice, rubbing along the ring before sticking the digit in.
Shadow blushes, gritting his teeth as he feels his first case of penetration from a foreign body. He clenches his fists but soon cannot hold back his pleasure. He breathes heavily and rocks his hips back against the thumb, but Andrews pulls it out with a pop.
Shadow growls, but soon yelps when Andrews wraps his arms around the hedgehog and pulls him up against his chest.
Shadow now is pressed against the human, presenting his whole front for the two observers. His cock throbs in anticipation as his flushed face loses focus on the world in front of him.
Andrews squeezes the hedgehog by the stomach, letting the quills scratch his chest. His lips rest right by Shadow's ear, and he whispers, "now, this is how you treat your superiors."
"Superior...?" Shadow asks, turning his head to face the human. He brushes his hand over the commander's cheek. "Nah... you're the ones giving me exactly what I want."
The Captain scowls. "That so, huh? You think you're in charge here?" He lowers the smaller creature down, the tip of his own head pressing against Shadow's asshole. "Let's just see!" The Captain lays down on the ground, bringing the hedgehog with him.
Shadow's toe-blobs touch the ground, and he reaches back to grab Andrews by the shoulders. He pushes himself down, taking the dick into his ass, swallowing it and wrapping around the length with a little bit of resistance.
Captain Andrews closes his eyes, his fingers scratching over Shadow's chest fur, but the hedgehog says nothing. He just smirks as he milks the commander's cock, gripping hard against the man's shoulders, letting his quills scratch his body. "You enjoying yourself?" Shadow asks.
The Captain doesn't respond, but instead buries his mouth against the hedgehog's neck, nipping at fur and flesh.
Shadow gasps at that, his hole tightening around the cock in surprise as Andrews thrusts himself upward into him. The cock prods him in just the right spot, hitting the prostate and sending Shadow into a world of pleasure beyond that.
Teeth and cock--two things Shadow hadn't considered coming together, but the marks the Captain would make on his fur were worth the experience. Shadow bounces over the Captain now, biting his lip as he looks down over his body, watching his cock flop around, feeling the jizz ooze and plop onto his thighs. He's a cum-drenched mess, but he hadn't come himself. Not yet, not-
Andrews lets go of Shadow's neck, holding him down as he lets out a weak cry. Cum shoots up out of the man and into Shadow's fuckhole, impregnating his ass with a soldier's potent seed.
Being so fulfilled, Shadow pushes his chest out, tilts his head back, and lets out a cry himself. Cum shoots out of him so far that Clayton and Mantle stumble back to let it spurt out onto the floor in front of him.
"Oh shit!"
"Fuck, man!"
Andrews pulls out and drops Shadow, leaving the hedgehog to lay on his side, his cock and his ass still leaking from the rough and wild sex he just had.
"Well," Andrews said, panting. "Whatever the hell this was... it sure was a wild ride. You're alright, Shadow?"
Shadow glances over his shoulder to see Andrews's hand held out for him. He grunts and pushes himself up. "I didn't do this for your approval," he says. "But if you need me, you know where to find me."
With that, Shadow returned to his shower, washing himself off and leaving the others to continue on in silence as well.

 Months pass, and Shadow tightens up a new part for his motorcycle and rubs his gloves on the oil rag as he checks on all the pieces. He frowns at something he sees in the reflection and tosses the cloth over his shoulder. "Been a while," he says, turning to face Rouge the Bat.
Rouge sits on Shadow's workbench, one leg crossed over the other. "Don't you seem better than when I left you. It's like you found yourself a hobby or something." Rouge says, a knowing smile upon her face.
Shadow sighs and rubs his hand over his quills. "Was it Omega?"
"Nope," Rouge says, uncrossing her leg and hopping off of the desk. "Just word around the water cooler in the espionage circles, and no, we don't spy on the locker rooms. But people talk."
"You here to congratulate me or to scold me?" Shadow asks, walking past her and putting his tools away.
"Neither, really. Just wondering how you are. You've always had issues when it came to figuring out your purpose in life, you know? Is this a new grand purpose, or is it another sort of thing?"
Shadow shrugs, "Honestly, I don't know," he says.
"Well, if you ever need help figuring that sort of thing out," She says, bringing her fingers up to her lower lip, "I just might be able to help you."
Shadow looks over his shoulder, quizzically quirking an eyebrow. "What do you have in mind?"
Rouge holds out her hand to him. "We'll see. But part of the fun is dealing with nice surprises. World's safe right now for the first time in a long time. Let's see what we can find out together."
