Chapter Text
This had to be the most fascinating thing Sonic had ever seen.
Amazing and otherworldly.
“Woah…” he all but whispered, enamoured and unable to come up with anything more intellectual.
Shadow grumbled where he lay under the blue hedgehog, legs spread out and fists gripping the sheets as he lay himself bare to the hero for the first time.
“Sorry.” Sonic apologised, voice breathless in his amazement. “It's just, wow. You're somethin’ else man, seriously.”
Shadow growled and looked off to the side with a whip of upturned quills, avoiding Sonic's admirable gaze, visibly overwhelmed and flustered.
“Just get on with it, hedgehog.”
Sonic sucked in his first breath in a while, “yeah, yep, right.” He muttered.
Shadow's genitals were like nothing the hero had ever seen, in all his years, on all his adventures. Never had he come across anything that came close to the amazing sight that was the ultimate lifeform.
Turns out Shadow had both, something that made sense to Sonic in the sense that it made him live up to the “ultimate” title he so greatly held onto.
What could be considered Shadow's “labia” had three elongated.. spines? On either side, six in total. And a wiggly tentacle-like member, only a few short inches long, extended in the place of a regular clitoris. Both of which were a dark bluish purple at the base, and faded into a dulled red, just a few shades darker than the hybrids bright, crimson quills.
Sonic's own length twitched at the sight, bobbing and heavy where it sat in between cobalt thighs. If Shadow had any insecurities about what Sonic thought about him, he need not worry.
The blue hedgehog couldn't be more turned on, leaking pre onto the sheets at a faster rate than he ever had before.
Sonic experimentally ran a finger over the flexible spines of Shadow's labia, immediately earning a sharp hiss from the hybrid. Causing Sonic's hand to shoot back into himself straight away.
“That okay?” He asked, hurried.
“I'm fine.” Shadow bit, his tan muzzle flushed a dark crimson. “Shut up.”
“Yeesh, okay. Sorry for caring about if I'm hurtin’ you.” Sonic replied flatly, clearly not impressed with Shadow's harsh tone.
“You're not hurting me just-” Shadow tsk'ed, “Just get on with it.”
Sonic's brow twitched, trying his best not to look angry or annoyed. And also trying to keep in mind that Shadow was just being snippy because he was nervous, hell. Sonic was nervous too.
The hero blew out a sigh, closing his eyes a moment to calm himself before reopening them with renewed determination.
“Okay.” He said, intentions clear.
Sonic decided to forgo a slow start and just dive right in, no different to how he would approach any new and exciting challenge presented to him.
He licked a long line from the base to tip of Shadow's clit-penis-tenticle-thingie, the spines along his labia curling at the stimulation. A possible attempt to grip at something that wasn't there just yet.
Shadow moaned, growly in the back of his throat and chest. Tipping his head back to smoosh red and black quills deeper into the pillows cushioning them.
“F-fuck.” He gasped.
“That good?” Sonic asked, flicking his bright emeralds up to the hybrid's face from where he leaned over his crotch.
“Y-yes!” Shadow grunted, vaginal spines quivering. “S-stop talking damn it!”
Sonic smirked, and licked another line up the member, making it shake and writhe against Shadow's abdomen.
“As you wish, princess.” He mocked, taking the length into his mouth before Shadow could retaliate with a quip of his own.
Shadow keened, back arching at the new stimulation. “F-fuck, fuck!”
‘Wow.. the mouth on this one.’ Sonic thought, mouth curling as he smiled around Shadow's length and gave it a hard suck.
“S-sonic! Damnit! Sh-shit!” Shadow grunted between every curse, a low clicking noise sounding out from somewhere deep in the hybrids chest. “Hah- ah”
Sonic couldn't help but comment, popping off Shadow's dick to say;
“Damn Shad's.” He chuckled, “You must really be pent up, huh?”
“Sh-Shut it, hedgehog!” He growled, his voice low and feral. Practically spitting at his rival.
“Uh-huh.” Sonic deadpanned, not saying another word as he resumed sucking off his rather grumpy, flustered counterpart.
Sonic felt movement below his chin, the soft labial spines of Shadow's sex fluttering in their hunt for stimuli. Sonic granted their wishes by tugging one experimentally with his thumb and pointer finger. Causing Shadow to release a shocked grunt above him.
Sonic glanced upwards to take in his rival's expression, not wanting to piss him off further by asking if he was okay again.
Shadow looked down at him with lidded eyes, panting and absolutely wrecked from just the smallest amount of stimulation. Clicks picking up in volume.
“Don't stop.” He answered Sonic's questioning gaze without the cobalt hedgehog needing to ask, whimpering around his next words. “Please.. Don't stop.”
The desperation in his words sent a rush through Sonic, the tips of his ears burning as his tail picked up its soft wag into a rather ecstatic fast-paced swish against the bedsheets.
Sonic bobbed his head with more vigor, twisting and pulling at sensitive, silky spines, as lewd wet sucking noises filled the space between them to join Shadow's deep, alien clicking-purr.
“Hahh- Oh shit!” Shadow gasped and panted, bare hands twisting so deep into the bedsheets that it looked semi-painful. “That's it Sonic.. T-that-” Shadow grunted again, squeezing his eyes closed, and gripped at the cobalt quills of Sonic's forehead to shove him deeper onto his writhing cock. “Don't s-stop.” He whined again.
Sonic rolled his eyes at the hybrid, ‘as if he planned to stop anyway.. but okay.’ And sucked at him harder, rolling his tongue over Shadow's tip on every upstroke, as he allowed the dark hedgehog lead his head in its up and down motions.
Sonic was thankful internally, that Shadow's length was on the smaller side. Surely had he been any bigger, the hero would have been choking quite terribly on it by now.
The spines around Shadow's entrance continued to flutter in and out, occasionally brushing against Sonic's occupied hand where it continued to tug and rub at the one caught in his grasp currently.
Some part of Sonic couldn't help but find it cute, he smirked around the length in his mouth as his chest tightened in adoration.
“S-sonic! I'm, I'm-” Shadow stuttered, and with one last shove to the top of Sonic's head, ebony thighs coming up to crush against the side of Sonic's head. The hybrid came with a loud moan, sticky fluid filling Sonic's mouth as the member twitched and writhed against the walls of his mouth. “Hnghhh!” Shadow grunted again, shoving Sonic down in time with the bursts of cum filling his mouth up. His own mouth hanging open, to allow his deep rumbled clicks to be free of his chest and throat.
Sonic squeezed one eye closed, the other struggling to stay open so he could watch Shadow with a grimace. Bracing both hands on the sheets beside Shadow's flanks to hold himself steady, as Shadow used his face for his own pleasure.
When Shadow finally relented with his passionate face-fucking, Sonic pulled back from him to sit up the moment he was able.
The blue hedgehog then scrunched his nose as he struggled to swallow Shadow's spend.
The fluid was tacky and sticky, similar to bubblegum in texture but not quite. Sonic smacked his lips as he tried to get a feel for it, the taffy-like liquid sticking to the walls of his mouth as he did so.
“Itsh shticky” He tried to say, words coming out weird before he was finally able to swallow the strange alien fluid with a rather dramatic gulp. “Huh, kinda sweet too.. interesting.” Shadow wrinkled his nose as he watched Sonic review his sample, clearly still struggling to catch his breath. “I'd give it like, maybe a six outta ten.” He laughed as Shadow attempted to kick at him, all while growling low in mild fury.
“Zip it you stupid blue hedgehog!” He grumbled, finally landing a blow to Sonic's hip, making the hero let out a stuttered, giggly “oof.”
“Hey! Not my fault you got weird alien gunk!” He laughed, poking fun at his counterpart's unusual texture and flavor. Earning him another swift kick. “Why's it all sticky like that anyway do ya think?” He asked genuinely.
Shadow rolled his eyes, exasperated.
“I assume it's to keep the ejaculatory fluid inside the female for proper copulation.” He stated monotone, as if reading from some freaky alien biology book.
“Okay yeah.” Sonic huffed fondly, “Sure, sounds about right.”
The hero then leaned over his rival, bracing both hands on his ebony chest to steady himself as he kissed him languidly.
“Are you ready to skip to the good part?” Sonic whispered against honey tan lips, smirking down at Shadow's flustered face with half lidded eyes. “Because I certainly am.”
Sonic leaned up again, sitting with his legs tucked under him and leaning back a little to show off his own hardened, leaking cock. He grasped the base of his sizable length to flick it up and down in a teasing manner, showing it off to his awaiting partner in a cocky display. (Litterally)
Shadow rolled his eyes with a huff, not for the first time that evening.
“Come on Shadow, don't keep a guy waiting now.” Sonic teased, earning more mumbled grievances from the huffy hybrid.
“Fine, yes. I'm ready. Now hurry it up hedgehog, slow doesn't suit you.” Shadow growled.
Sonic barked a laugh at that one.
“Oh yeah? That we can agree on.” Sonic shuffled forward to brace the tip of his cock at Shadow's entrance, the labia spines spreading out instinctually to give him room to enter. “Good thing I like to go fast.” Sonic rumbled, and pushed himself inwards.
Easily slipping into Shadow's slick heat.
The two simultaneously moaned as Sonic slid into his counterpart, shuddering as he got a feel of Shadow's insides for the very first time.
Shadow was silky, wet and oh so amazingly textured. The insides of his walls were similar to what a shag carpet may feel like if it were wet, warm and silky. Sucking and clenching around Sonic's cock to welcome him as he pushed further inwards.
“Holy shit.” Sonic hissed, groaning low and furrowing his brow in concentration. “You feel incredible, dude. What the hell.”
Shadow only grunted and gripped the bedsheets at his sides tighter, biting at his own lip as he was carefully penetrated by his rival. The only indicators of his enjoyment, being the dull tap of an ebony tail against the bedsheets, and the soft clicking that began picking up again the minute Sonic began to spear him.
Sonic bottomed out, and Shadow's spines wrapped around the base of his cock once he was situated. Practically hugging him to keep him close, while Shadow's own cock curled itself into a tight ball of pleasure.
“F-fuck.” Sonic huffed, “man, how am I supposed to last when you feel like that?” He mused, a soft laugh escaping peach lips.
Shadow huffed a cocky laugh, “Figure it out, faker. Now move.” He demanded in a low growl.
Sonic smirked back at the challenge, “You're so on.” He growled in his own deep rumble, grabbing one of Shadow's thighs at the knee-ditch to hike it up over his own hip. Before rutting into his rival with a rather obscene squelching sound.
Shadow groaned and threw his head back, back arching off the bed as Sonic began a steady pace.
“Haah- S-Sonic!” He shouted, clicking louder at every thrust forward.
“Ngh-” Sonic groaned and panted, “N-not so. Hah- Not so tough now, h-huh Sh-shadow?” he laughed, pulling Shadow's leg up further as he leaned over the hybrid menacingly. “F-fuck, baby. Damn.”
Shadow had his head tilted back still, but kept his half-lidded crimson gaze zeroed in on Sonic's face. Glaring and refusing to miss a thing as the hero rutted into him more and more forcefully. The hybrid's mouth stayed open a little so he could pant, grunt and click, unable to say much else with the long, thick cock rutting deep into his needy canal.
Sonic was so big it slightly hurt, but the wetness of his natural slick made it easy for the hero to slide himself home inside his rival. Fast and hard, a pace that would be winding Shadow, had he not been an alien hybrid with unnatural anatomy and strength.
Sonic slammed the hand not occupied by Shadow's leg into the headboard above the hybrid with a loud yell of “Shit!” As he scrunched up his nose and shut his eyes, pressure building between them from the overwhelming pleasure Shadow's cunt provided.
“Fuck, you feel so good.” Sonic opened his eyes to stare down at his counterpart, passionately looking him in the eyes through his lashes. “That feel good, baby?” he drawled.
Shadow grunted and keened, nodding slightly when his voice failed him.
“Yeah?” Sonic huffed, “Y-yeah- good because.. DAMN!” Sonic grunted again and picked up speed with a few rough, wet slaps of fur on fur. Before slowing down once more in an attempt to try and speak. “B-because.. man, I won't be able to keep off ya after this.” Sonic sighed at a particularly tight clench from Shadow's cunt. “F-fuck.”
Shadow released his hold on the bedsheets, giving them a break in order to wrap striped arms around Sonic's shoulders. Sonic gripped the headboard and Shadow's knee ditch harder in response, digging his blunt claws in and panting sporadically above him.
Shadow swallowed as he tried to find his voice again.
“F-fill me, hedgehog.” He growled, low and feral as if he were a wild animal in heat. “S-show me that I'm yours damnit.”
Sonic moaned low, releasing the scratched up headboard and grabbing Shadow's cock to stroke it in a frenzy. Clearly spurred on by Shadow's passionate lust-filled words.
Shadow's pussy fluttered and clenched around Sonic, making him swear over and over as he worked his rival roughly.
The bed rocked under them, slamming the wall and skirting across wooden floorboards with the intensity of their coupling. The noises being drowned out by the ones being made by both overpowered hedgehogs, as they quickly neared their peaks together.
Sonic's next words were equally as feral as Shadow's had been, his voice the most growly Shadow had ever heard it.
“I-I'm gonna breed the hell outta you, man.” He panted before continuing. “F-fill you up s-so so d-deep.” Another gasp. “F-fuck, Shadow!”
Sonic slammed into him one more time with a loud squelch, causing Shadow to be shoved backwards into the pillows as Sonic came intensely.
“H-Holy shit, holy shit..” The hero rambled pathetically, while attempting to keep up stroking Shadow.
His pathetic tone, being pussy-drunk on Shadow caused the hybrid to fall over the edge with him. Squeezing and tensing as he came with a deep shouted “S-sonic!” His loud clicking purr not ceasing either.
Sonic lowered his head once they were both done, resting it against soft, heaving white chest fur.
“Fuck Shadow..” Sonic chuckled, “That was insane.”
The blue hedgehog sounded drunk, voice a wreck and breathing ragged as he began to slowly come down from the rush of euphoria. Shadow matching him with exhausted fucked-out breaths of his own.
Sonic kept his softening cock buried in Shadow for a short while, his labial spines still trembling slightly and holding onto Sonic as if they never wanted him to leave. (And if it were up to him he wouldn't) but eventually he had to.
Sonic pulled out of Shadow with a low groan, the hybrid's sex clearly not wanting to be left empty as it attempted to suck the hero's member back in to no avail.
The hero looked down at the mess he had made of his favorite rival, spreading one of his lips open to watch his own spend slide out.
“Man, that's hot.” He mused with a click of his tongue. “Yep, I'm definitely not gonna be able to keep off ya now.” He laughed, still sex-drunk from their intense session. “Damn.”
Shadow groaned again, shoving Sonic away by the shoulder so he could sit up properly. Cringing at the tacky feeling between his legs.
“You're disgusting.” Shadow insulted, earning a low chuckle from his blue counterpart.
“Yeah, but you liked it, clearly.” He taunted, leaning in to capture tan lips with his peach ones. “And I like you~” he tacked on, smiling against Shadow's soft lips.
“Pheh” Shadow huffed, just barely a laugh.
“Pathetic blue hedgehog.”
