Chapter Text
When Sonic reoriented himself and could feel his feet on the ground again, he felt the hardwood floor of Shadow’s bedroom rather than the grass outside the club. The apartment Shadow shared with Rouge was dark and cold, neither having been there for some time. Sonic took a deep breath, squinting his eyes as he searched for Shadow’s hand in the darkness, the only light provided to them being the glow of the street lamps coming in from the windows. His face burned from his chest to the tips of his ears and his heart was nearly beating out of his ribcage. They had just made out against the brick wall of the club, but had no real discussion of what was going to happen, or what they were now. Anxiety bled into Sonic’s arousal.
He rocked back and forth on his heels. “So, uh,” he whispered. “What do ya wanna do now?”
Shadow scoffed and roughly pulled him so they were chest to chest. "Shut up," he said as his mouth found Sonic's again. Shadow kissed him rough, hard, hungry, pushing him back yet keeping him close at the same time. He let out a soft noise as his back hit the wall, strong gloved hands holding his shoulders and pinning him. "Idiot," he mumbled against swollen peach lips.
Sonic poured years of repressed feelings onto Shadow’s tongue as it entered his mouth, making the kiss sloppy as the dark hedgehog began tugging on gloves under gold inhibitors. Shadow’s knee wedged itself between his legs to keep him upright as bare fingers dragged along blue sides, leaving goosebumps in their wake. His head swam from the searing heat trapped between them as they stood in each others’ space. He wrapped his arms around Shadow, pulling him closer. Sonic’s heart was beating as fast as he could run, he wondered if Shadow could feel it. Their lips moved together in a heated dance; he was breathless and dizzy and there was nothing he could do about it, nor did he want to. This was the one fight between them that he willingly chose to forfeit.
Shadow ripped himself away from Sonic's lips, dipping down to instead mouth at his neck, fangs teasing along the sensitive flesh. He gave Sonic no time to recover, nibbling and biting every inch of skin he could find. Sonic whimpered as his grip on Shadow tightened, wordlessly begging him to continue. Obliging, Shadow slowly moved from his neck to his shoulder, his chest, and down his abdomen, peppering kisses all the while. His head thumped against the wall, partly out of embarrassment, and partly because he had a feeling that seeing Shadow in the dim light that filled the room would make him completely lose the little composure he had left.
Sonic felt a tongue on his pouch and he let out a sharp gasp. Shadow started alternating between licks, kisses and nips to encourage him out, thumbs caressing the fur of his abdomen. Gripping Shadow’s shoulder tighter, he was becoming a panting mess, ears canted forward, cheeks bright, legs wobbly. His hand moved up the wall to try to find more stability as Shadow’s hands moved to his thighs, adding extra stimulation and leaving tingles in their wake.
Sonic felt a tap on his thigh. He lifted his head off the wall slowly and looked down at his partner, who was situated comfortably on his knees, Sonic’s half-exposed dick right in front of his face. Sonic thought he might die. This was single-handedly the hottest thing he’d ever seen; the object of his fantasies in such a submissive position driving him too close to orgasm for comfort. He could feel how worked up Shadow was by the way his fingers trembled against his leg, how hot his skin was where they met, his puffs of air against his sheath.
“I’ll ask you one more time–do you consent?” Shadow whispered in the space between them, so close to where Sonic wanted him.
Sonic nodded rapidly and huffed, eyes half-lidded. “Fuck, Shadow, obviously.”
His rival didn’t respond, instead choosing to palm Sonic’s pouch. Green eyes rolled back as his length slid out and into Shadow’s waiting hand, his head thumping against the wall again. Shadow pumped him experimentally a few times causing Sonic’s hips to involuntarily buck forward at every slow stroke. The hero let out a dramatic whine when the pressure was removed and light kisses started trailing up his shaft.
“C’mon…” Sonic murmured in frustration.
“Impatient, are we?” Shadow asked with a cocky smirk, now trailing two fingers up the sides of his still concealed dick and brushing his thumb against the head.
He sighed at the little bit of pleasure he was given. “Can you just get on with it?”
“Hmph,” Shadow hummed and moved his hand, now only using one finger to brush up the side of Sonic’s leg. “Since you want to be such a brat, beg.”
Sonic lifted his head to meet Shadow’s eyes. “What?”
“You heard me. Beg. Tell me what you want.”
Well this took a turn. Sonic growled softly, frustrated, but no less aroused. If anything, submitting to his rival was turning him on even more, knowing that the things they did here in Shadow’s bedroom would stay here, and that their budding relationship would have no effect on their long-term rivalry.
Shadow began to tease him, trying to get him to beg by licking up Sonic’s thigh, running his tongue back up to his dick slowly. The hero’s senses were alive, Shadow’s scent of cinnamon and lavender wrapping around him like a blanket, keeping him chained to reality as his mind tried to submit to the heavy lust that surrounded them. The teasing was becoming unbearable, short licks and fleeting touches that made him yearn for more. Shadow had been on his mind for years, the thought of this the plot of every sexual fantasy he had ever had, and now that it was within his reach, his patience had run out.
“Fine, fine, fine!” Sonic said quickly, his foot restlessly moving back and forth on the floor between Shadow’s knee and the wall. “Please, Shadow, please touch me, I can't take it anymore…”
He was cut off as Shadow took Sonic in his mouth with no warning. The hero moaned loudly as he was engulfed in delicious heat, and by the way Shadow’s ears flicked toward him, he knew that the other liked what he was hearing. His knees buckled and he made a strained sound as Shadow gripped his hips firmly to keep him standing while continuing to bob his head.
Sonic’s senses were in complete overload, it was maddening: the temperature difference when Shadow pulled back, how his tongue moved against him, the dangerous teasing of his teeth, all of it added together to drive him insane. Sonic’s back arched off the wall as he greedily tried to push deeper into Shadow’s mouth. Wet lips wrapped around the base of his cock as Shadow's nose buried itself in his abdomen, and Sonic felt his tip hit the back of Shadow's throat.
“F-fuck, Shadow…” His hand moved from Shadow’s shoulder to his head, tangling in black and red quills. Shadow pulled back and pushed forward again, deepthroating him while swirling around him with his tongue. How Shadow even learned to do that was beyond him. Through the haze of sensations, he could feel bare hands treading up through the fur of his thighs, stopping at blue hips, bringing them forward in a shallow thrust.
He felt the muscles in Shadow’s throat contract around him as he gagged slightly, the sensations around his dick ceasing for only a moment as his rival coughed and inhaled before going back in for more. He picked up the pace, seemingly getting used to the sensation as the constriction of his throat around Sonic’s dick grew few and far between. Sonic grew breathless as his hazy mind registered what Shadow was asking.
“You’re serious?” Sonic whispered.
Shadow’s jaw relaxed and he moaned softly around Sonic’s dick, barely audible but the vibration sent shivers down Sonic’s spine. He cursed as he held Shadow’s head and pulled back slightly, then slowly starting to fuck Shadow’s mouth.
If Sonic were to tell anyone that the Ultimate Lifeform had been on his knees for him, he was certain no one would believe him. Yet here he was, deepthroating with a finesse Sonic had no idea he was capable of. Shadow had an almost desperate look in his eye, clearly enamored with having Sonic down his throat. He bobbed his head faster, meeting Sonic’s shallow thrusts and working the full length of his erection, both of them working to keep up with each other.
Sonic was a mess, Shadow’s name mixed with moans and other incoherent words that rose with volume and intensity with every push and pull. Dark hands ran up and down his waist, the simple touch electrifying and aiding in pushing him closer to the edge simply because it was Shadow.
“Shads… I’m close…” Sonic warned him, still fucking Shadow’s mouth.
In response, Shadow hummed, gripped his hips and pulled him as deep as he could go.
With a shout, Sonic’s orgasm pulled him under, the steady hands still on his hips were the only thing keeping him upright. Through the haze of pleasure, he felt Shadow swallow around him, the movement simultaneously prolonging his orgasm while quickly becoming overstimulating. He weakly pushed Shadow’s head away from his oversensitive dick and slid down the wall onto his ass, breathing heavily and basking in the afterglow. Shadow, still on his knees in front of him, scooted closer so he could lean in and kiss him. Sonic moaned at the salty taste of himself still on Shadow’s tongue.
“I never knew you could do that,” Sonic said as he pulled back and chuckled.
“How would you know?” Shadow responded, a rare soft smile gracing his features.
“I dunno, man, my brain isn’t working right now,” Sonic leaned back against the wall, still panting as Shadow moved to sit next to him. The blue hedgehog turned and captured tan lips in a slow, soft kiss, so different from the ones they were sharing before, Shadow’s hand moving up to carefully cup his cheek, tenderly running his thumb across short fur there.
“Shads,” Sonic continued when they finally parted, still panting, “what does this mean?”
Hand unmoving, glowing eyes like magma and amber scanned his face like he was the most precious thing in the world. “What would you like it to mean?”
Sonic shifted in his place on the floor. “I would like it to mean we do this again? Like more than once? And often?”
“Are you just asking me to please your horny ass?” Shadow chuckled as he stood, grabbing Sonic’s hands to help him stand as well.
“Actually, I’m asking you to fuck my horny ass. But with the relationship stuff too, because, ya know, like I said, I really do want to be with you. It’s not just a sex thing.”
The dark hedgehog blended into his namesakes so well that without his hand in Sonic’s guiding him and the deep timbre of his quiet laugh reaching his ears, he would have thought that Shadow was no longer there. “You’re incredibly impatient,” was the last thing Sonic heard before he was turned and shoved hard across the room, a shocked yelp leaving him as he landed on a soft duvet.
He felt Shadow’s warm body crawl against his own so that the dark hedgehog hovered over him, their mouths inches apart. His chest already rose and fell in steady, shallow pants at the feeling of black brushing against blue. He knew Shadow could see him clearly despite the dim light, could see his searing blush and how he tried to shift his legs to try and fail to cover his growing erection, embarrassed at how fast he was getting worked up again.
“Where did all that cockiness of yours go, hedgehog?” Shadow whispered as he leaned down and licked up the shell of a blue ear, causing Sonic to let out a soft whimper. “Tell me what you need.”
Sonic blinked and opened his eyes to try to find Shadow’s in the heavy darkness that shrouded his bedroom. “The truth,” Sonic challenged, breathing still ragged.
This seemed to make Shadow pause. “What?”
“The truth, Shadow. Do you want a relationship with me or not?” Sonic put his hand on Shadow’s chest to prevent him from continuing their activities. They had made out at the club and now they were in Shadow’s bed, but that didn’t mean anything.
Breathing into the space between them, Shadow hesitated. Sonic took in how his partner looked down at him with an adoration he’d never seen from him before. After only a beat of hesitation, Shadow spoke so close to his lips, Sonic could feel his breath softly teasing.
“Before you, I had never met someone who could infuriate me within seconds, yet make everything he did look so effortless.” Shadow sighed, “Somehow, my falling for you was just as effortless. Your attitude and perseverance drew me to you ever since that day in the city, but your compassion and drive made me want to protect you, despite you being strong enough to defend yourself.” Shadow said slowly, eyes darting around his face. All Sonic could do was lay there in awe, muzzle bright pink and watch his crush of so many years work to tell him he felt the exact same way. It sent his heart into the sky with elation.
Shadow inhaled deeply and Sonic saw ruby eyes lock on to him, gathering courage, then moved to lay on his chest, face buried in his neck. “If you truly want me, I’m yours. Whatever you want from me, I’ll do it. You have shattered me and put me together over and over. I won’t ask you to continue to feel like you’re responsible for my well-being, but I’d like to have a hand in being responsible for yours, if you’ll have me.”
Sonic’s jaw hung open. He didn’t know what he expected, but it certainly wasn’t a confession that sounded straight out of a steamy romance novel.
Getting his bearings, Sonic chuckled and softly kissed Shadow’s cheek. “Since when are you a romantic?”
Shadow growled into his neck. “Shut the fuck up.”
“I’m kidding! I’m kiddi-AH! Shadow!” Sharp teeth pierced the flesh of Sonic’s neck hard, the pain quickly turning into pleasure.
A soft tongue replaced teeth as his partner licked over the mark, an apology for the rough treatment. He sat up a bit, face just as close to Sonic’s as it was before to meet his eyes.
“Are you satisfied now?” Shadow whispered.
“Not even close,” came Sonic’s reply as peach arms grabbed black and red quills and forced Shadow’s mouth against his in a sloppy, heated kiss that was more teeth and tongue than lips.
They rocked into each other in a rhythm all their own, Sonic somehow wanting him so much more after his heartfelt confession. Although he didn’t have the same way with words as his rival did, he was determined to show him the same devotion and vulnerability with his body.
Shadow growled and moved Sonic’s hands from his dark quills and tore the blue hedgehog’s gloves off, never breaking the kiss, which just made more blood rush to Sonic’s groin. Grinding against the strong hips above him, bare hands, now free of their fabric constraints, glided up soft black fur on Shadow’s back.
Sonic moaned softly at the feeling of the other’s hardness, creating just the right amount of friction against his sheath to make his length start to make a re-appearance.
“You’re perfect,” Shadow murmured against his lips, finally breaking the kiss, making his hips jump again. Hearing such sweet words come from the dark hedgehog only made Sonic’s body burn hotter.
“You will tell me if you want me to stop,” Shadow commanded, sitting up and spreading his partner’s legs as his dick slipped out of his sheath.
“Uh huh,” was all Sonic could manage to reply as a wet finger slowly circled his hole and his eyes locked on to Shadow’s cock. He was so far gone, he couldn’t even comprehend why Shadow’s finger was suddenly wet.
He hissed as the tip of Shadow’s finger slipped inside, the stretch unfamiliar. “You need to relax,” he heard his partner’s raspy voice, but it barely registered. Sonic did his best to comply nonetheless as he tried to slow his breathing and make it easier for them both, but it all felt so damn good.
The digit pumped in and out of him slowly, stretching and circling his insides. Shadow leaned down to kiss him again, deep and slow. “Fuck, yes…that’s so good,” the hero murmured against his lips, lifting his hips in time with Shadow’s fingers.
He was worked open far slower than he wanted, but he truly couldn’t complain when Shadow moved that talented mouth back to his neck, leaving soft kisses and nips that sent bolts of lightning down his spine, and hearing the appreciative low moans that his partner let out into the soft fur of Sonic’s throat with every thrust.
The hand that wasn’t inside him moved to his hip, claws digging into flesh holding him still as a second finger entered him, making Sonic let out a loud cry. Most of Shadow’s weight was on top of him now, both of their bodies kindling the heat of a thousand fires.
The digits curled up inside of him, and Sonic knew what Shadow was looking for. When he finally found it, there was no more holding back. The moan the hero let out quickly turned into “Fuck, Shadow, please. Please fuck me.”
An appreciative growl vibrated against his throat, adding to the sensations thrumming under his skin. “That’s right, hedgehog, beg for me.”
Shadow’s fingers continued to pump mercilessly in and out of him, drawing more quick and loud moans out of him and bringing him closer and closer to the edge. “Fuck, Sonic,” the dark hedgehog whispered against the soft blue fur of his neck.
The hero shivered at the sound of his own name. “Chaos, please…need your dick, I-I want you inside,” every other word punctuated by panted breaths.
Shadow removed his fingers and slowly sat back on his haunches, making Sonic whine at the sudden lack of stimulation. “Get on your hands and knees, then.”
Sonic’s eyes flew open as he quickly twisted and rose to all fours. Fuck. The idea of him getting fucked this way, especially in the dark, making it absolutely impossible to see anything would make everything so much hotter. All he would be able to do was feel, and take what Shadow wanted to give.
He felt Shadow line himself up behind him, his wet dick gliding effortlessly across his hole to tease. A hand gripped his hip again, the sharp sensation of his claws threatening to leave more marks making Sonic rock back against him, silently begging.
The warmth of the man above him radiated across his back as Shadow leaned forward to whisper in a blue ear, “You’re all mine,” as he finally, agonizingly slowly, pushed into Sonic’s tight heat.
He shivered and scrunched his nose at the uncomfortable initial stretch as the Ultimate Lifeform claimed him inch by inch. Sonic knew he was trying to make it as painless as possible while also trying to control his own urges, gaining progress over several minutes. Shadow’s breathing was shallow and the grip on his hips was bruising as he gently retreated and pushed back in, more of his length breaching him with each movement. Sonic felt his partner kiss the side of his neck, arms wrapped around his middle. The blue hedgehog started to make more pleasurable noises as the drags in and out of his hole became longer.
Shadow finally bottomed out and green eyes rolled to the back of Sonic’s head as he finally got what he wanted for so long. Shadow filled him so completely, he hadn’t been able to fully appreciate his partner’s length with his hands, but he certainly felt him now.
After a second to adjust, Sonic felt Shadow begin slow, short thrusts, pulling his hips back to meet the dark hedgehog’s own. Shadow’s shallow breaths ghosted against the back of his neck, obviously trying to keep his composure.
Shadow moved his hands up to and then down Sonic’s chest, abdomen, thighs, and back up again until one wrapped around his cock, working it in time with his thrusts. He whined and pushed harder against Shadow’s hips, hitting his prostate as a result.
Sonic’s whine quickly turned into a moan as he fell forward onto his forearms, Shadow unfazed as he continued stroking him. He rocked back against every thrust, trying to encourage his partner deeper, reaching for every possible inch. “Harder,” Sonic mumbled.
“You’ll get what I give you,” Shadow snapped, tone sharp but with no real venom. The hero huffed into the fur of his forearms, both aroused and frustrated by Shadow’s domineering attitude.
Sonic felt hot air against his ear before Shadow spoke again, deep and rough. “Look at you, taking me so well. Is this what you wanted? Was it me you couldn’t stop thinking about, or was it the idea of my cock splitting you open?”
Sonic bit his own arm to keep from making any more embarassing noises because Chaos fuck, he never imagined the Ultimate Lifeform to be capable of saying such filthy things. The hand that was on his thigh traveled tantalizingly upward until it stopped on his neck. Shadow gripped his throat and pulled him up, making Sonic squeak. The pressure was just enough to tease danger. His other hand continued to work him as he was fucked, even faster now.
“Well? Answer me.”
Sonic panted and threw his head back, welcoming Shadow’s hand on his neck. “Yes,” he moaned.
“Yes what?” Shadow asked as he gave his partner a particularly punishing thrust, making Sonic stumble forward, but not letting him fall.
“It was you…ah, everything about you,” Sonic moaned. The dark hedgehog’s pace was becoming erratic, holding him upright by the throat as he pounded roughly into Sonic’s ass, the angle making it so Shadow hit his sweet spot with every thrust. The hand on his dick never slowed, twisting around the head so good before it slid to the base and back again, the rhythm pushing him closer and closer to an edge he wasn’t sure he wanted to meet yet.
“That’s what I thought,” Shadow whispered in his ear before Sonic felt soft kisses on his shoulder. “I want to know what you imagined,” His grip on his neck tightened again and Sonic moaned roughly as his airway was played with. “Was it this? …Or what about this?”
Shadow’s hand left his throat and Sonic had less than a second to take a breath of the air he was nearly denied before he was shoved forward on his arms again, and the hand that was on choking him tangled in his quills and pulled hard. Sonic yelped. “Holy shit.”
“I always knew you liked it rough,” The hero could hear the sly grin Shadow wore. “Damn, even more beautiful than I imagined when I touched myself.”
Chaos. Sonic’s body was becoming hotter and hotter, that familiar pressure coiling low in his belly and breaths short and erratic. “Sha-Shadow…gonna cum…”
“Cum for me, then,” Shadow licked up his ear as Sonic stiffened, crying out as jets of cum shot up and on his belly and chest, coating Shadow’s fist as he continued to work him through it.
Sonic shuddered through the last aftershock and slumped forward as his partner released his quills from an iron grip. Shadow was still slowly thrusting into him, making his head loll to either side. Shadow’s hands moved from his back and his dick to his hips.
“I’m going to fucking destroy you.”
Shadow gave him no more time to recover as he was shoved forward and roughly pounded into, desperately chasing his own climax.
Sonic cried out in overstimulation from the abuse of his insides. Shadow leaned down and bit into the flesh of his shoulder, prompting a yelp that quickly turned into a moan as the pain turned into white hot pleasure.
“I’m going to fill you…make a fucking mess out of you…” Shadow mumbled into his shoulder as he punctuated his sentence with a quick, rough thrust, signaling his end.
Sonic brought a hand to cover Shadow’s on his hip as he felt the hybrid shudder and grind deep inside him as he came, filling the hero with warm seed. Sonic moaned again at the feeling of Shadow’s cum deep inside him before relaxing his shoulders in sweet relief.
They laid together for what seemed like hours, recovering while simultaneously comforting each other. Shadow slowly pulled out, cum slowly oozing out after it, and rolled into the spot next to him as Sonic winced, he was going to be sore tomorrow.
“Are you okay?” Shadow asked after another moment of silence.
Sonic chuckled. “Yeah, I’m good. You?”
The dark hedgehog leaned over into Sonic’s space, pulling him close. “Never better.”
Sonic smiled and cuddled up next to his new personal space heater, intent on going to sleep, but remembered his question from earlier. “Oh, hey, I wanna ask you something.”
“Mhm,” Shadow mumbled.
“Where did you get the lube from? I didn’t see a bottle anywhere.”
Sonic felt Shadow tense. “I produce it. I self-lubricate.”
Sonic looked up at his partner. “Wait, really? That’s so cool!”
“It is?”
“Well, yeah,” Sonic started to slur his words and nestled his head into the crook of Shadow’s neck. “‘S convenient and stuff, but it’s different, and I like everything that makes you different.”
Sonic drifted off to sleep surrounded by the scent of lavender and spices, not noticing the flustered expression and bright blush that Shadow wore as he wrapped his arms around the blue hedgehog just a little tighter.
