Being the world-renowned ‘Mobian hero’, and the highly celebrated ‘Fastest Thing Alive’ often got to be utterly exhausting.

Sonic always had too much energy pent up inside for his own good. Continuously saving the world from the constant, looming threat of evil wasn’t an easy task in the slightest, and even the Blue Blur needed to find ways to take the edge off. 

It wasn’t Sonic’s fault that his preferred ways for relieving said edge weren’t the most… Ideal to those around him. 

Nearly everyone in Sonic’s life has told him to stop his routine sparring with his favorite rival. 

Both Amy and Tails said that the reason Sonic and Shadow’s relationship was so ‘underdeveloped' was because they never talked to each other, choosing to talk with their fists instead. Amy told him that maybe if they stopped trying to claw out each other’s throats every time they got the chance, they could actually be friends.

Tails was worried that Shadow was too… Intense in his sparring. He’d notice Sonic coming home with his nose bloodied and his face bruised on more than one occasion. To him, sparring should be light and friendly and shouldn’t end in bloodshed. 

Sonic and Knuckles also got into arguments over the topic. Knuckles would insist that the fighting was pointless, that a fight that had no real reason for occurring and no true conclusion was a complete waste of time, and that it could be spent on more important things. Sonic always disagreed though, he argued against every single reason they gave for why they should stop.

 They just couldn’t understand the way Shadow was with Sonic. He was a completely different person whenever Sonic managed to get him alone. 

There was something about the thrill he got from fighting Shadow that he couldn’t get anywhere else. He’d spar with Knuckles sometimes as well, but that was friendly, brotherly. His fights with Shadow were passionate, intense in a way that Sonic couldn’t put words to. With Shadow, he didn’t have to hold back, in fact he was sure the hybrid would kill him if he tried to. 

Sonic considered all of his friendships important and extremely special, but they would never be Sonic and Shadow. 

-

It was late one night, and Sonic was wide awake, planning his grand escape. It had to have been way past midnight as Sonic crept out of his small bedroom. Tails’ place was small but very comfortable. Still not having the most stable living situation, Sonic would crash there a lot. So much in fact, that he had his own room right across the hall from his brothers. 

Sonic loved the time he spent with Tails, and it was made even better by Knuckles staying over as well. He’d made it a habit to come visit whenever he took a break from guarding the Master Emerald, however in this moment Sonic really wished he were in the house alone. He doubted either of them would approve of him sneaking out in the middle of the night, let alone approve of the reason for his secrecy. 

He tried to make as little noise as possible as he tiptoed down the hall towards the living room, and he’d all but made it to the front door and was about to turn the knob when-

“Sonic…?” 

The sudden voice startled Sonic so much he nearly jumped out of his skin, internally grateful for the fact that he was able to stifle a shriek. 

Knuckles sat up on the couch, raising an eyebrow at Sonic in suspicion. “What in chaos are you doing?” 

Sonic rolled his eyes, trying to play this off as best he could. Knuckles didn’t exactly have a bedroom, so he tended to take the couch when sleeping over. He couldn’t believe that he was so eager to see Shadow that he’d forgotten that very important detail.

 “Jeez, you’re not my dad, Knux. I just… Couldn’t sleep, so I was gonna go on a run to hopefully let some energy out.” He grinned nervously, hoping it was a convincing enough story. Knuckles saw right through it though, crossing his arms and narrowing his eyes. Sonic never was a very good liar. 

“Don’t act like I’m dumb. You’re going to meet up with Shadow again aren’t you?” His eyes only narrowed further as he waited for Sonic to stop shifting back and forth and answer the question. 

After a few seconds he cracked, groaning as his shoulders slumped. “Ugh, Fine! Yes, I’m gonna see Shadow, not like it matters. Why do you care anyways? You act like you hate the guy.” 

Knuckles crossed his arms. “I don’t hate him, I just don’t understand your ridiculous fighting. Do you two ever do anything else? Like have a normal conversation? Or hang out? Or not try to actively kill each other?”

“We’re not trying to kill each other, ” Sonic emphasized. “And we do… Some of those things. Not that it’s any of your business.” 

Sonic was admittedly quite stingy when it came to Shadow. Or at least he was when it came to his relationship with Shadow. He didn’t like divulging too many details about the things they did, even if they didn’t exactly do much. Their relationship felt special, and Sonic didn’t want to share too much of it if he didn’t have to. 

“You know what, fine. Since obviously I won’t be able to stop you.” Knuckles slumped back into the couch, waving Sonic off. “Go have fun beating the shit out of each other.”

Sonic grinned, opening the door and stepping out. “Thanks, Knux. I should be back by morning… Hopefully.” 

Knuckles rolled his eyes, but Sonic could’ve sworn he saw a small grin on his face. “Yeah, whatever. I’ll let Tails know you’re out running if he wakes up before you’re back, and Sonic?”

He paused his stride, looking back at him fully. “Yeah?”

“Just… Don’t get too carried away, alright? See you later.” With that, he fully laid back down on the couch, turning his back to Sonic completely.

Sonic was a bit confused on what he meant by that, but he’d take it to heart regardless. “Alright, see you when I get back.” He gave a little wave before closing the door, speeding off in a flash. 

-

Sonic and Shadow had lots of spots they’d use for sparring, rotating between them whenever one would get dull. They did have an agreed-upon favorite though; a large hill with a huge grassy field at the top, dotted with lavender and wildflowers. Sonic liked how dramatic it felt to fight up there, he had lots of memories of leaving their fights each with flower petals clinging to their fur, and he always thought it made Shadow look kind of… Cute. 

Shadow said he liked the spot for how open it was and that it was secluded and quiet, but Sonic had a feeling it was also because of the flowers. Shadow had told him that he had a love for them a couple weeks ago during one of their talks. He remembered that night with a lot of fondness, he loved how unguarded Shadow was after fighting. Sonic doubted he would’ve been too willing to tell him about that part of him in any other context. 

Sonic made it to the top of the hill in under two minutes where he found Shadow waiting for him, arms crossed over his chest. 

“You’re late.” 

Sonic smirked at the muttered statement, coming up to stand right in front of his rival. “Good to see you too, faker. I don’t remember having a set time.”

“Well according to me, faker, you’re late.”

“Then do you wanna go, Shads? Or do you wanna keep lecturing me on punctuality?”   

Shadow returned Sonic’s smirk, assuming a more defensive position. 

They hadn’t done this in a couple weeks and it showed through their energy. The air was heavy with anticipation. They used to meet up almost weekly, but Sonic’s friends forced him to stop for a while after he came home with an especially bad black eye.“You know why I’m here. You think you can handle it? Or do you need me to go easy on you?”

Sonic laughed, he could banter with Shadow all day. He didn’t even really mind the breaks they took, because it just meant they went harder the next time.  

“Aw, c’mon Shadow, I thought you knew me better than that,” He pouted, copying Shadow’s stance and getting ready to lunge at him. “You better not hold back, ‘cause I won't.” 

Instead of whipping back another witty remark, Shadow surged forward, aiming a punch directly at Sonic’s jaw. He dodged it easily, spinning around to land a kick at Shadow’s ankles, hoping to catch him off guard but he jumped out of the way at the last second. He was able to land his next punch right under Sonic’s eye, making him stumble back momentarily but he recovered just as fast, launching himself at Shadow’s chest and knocking the wind out of him. 

He watched as Shadow’s demeanor quickly changed and determination clouded his eyes. He growled lowly, socking Sonic in the arm before kicking him in the side.

Sonic grinned, retaliating by grabbing a fistful of Shadow’s quills, pulling him back roughly and shoving him to the ground. 

In a flash, Sonic was on top of him, trying to land in as many punches as he could before their positions were switched, with Sonic now lying beneath Shadow, his hand around his throat as Sonic continued to pull at his quills before leaning his arm back to punch him square in the lip. 

Shadow paused for a moment, still not removing his hand from Sonic’s neck. With the other, he reached up to feel where his lip split, smirking as he felt some blood drip down to his chin. 

“Not bad faker,” Shadow smirked, his grip on Sonic’s neck becoming tighter. “But is that all you’ve got?”

The hand around him only became tighter and Sonic struggled against the grip, scratching at Shadow’s hand. He watched, still not giving up his fight as Shadow licked the blood from his own lips, still staring down at Sonic with that predatory grin. 

“S-Shads, fuck- Wait-” His voice was breathy and Shadow’s grip wasn’t loosening, but Sonic wasn’t afraid. It felt good. The way Shadow was looking at him had Sonic internally asking for more. Now wasn’t the time to unpack all of that though, he still didn’t want to be suffocated to death right now. 

“Shadow!”

Upon hearing his name again, Shadow seemed to snap out of his haze, the dark look in his eyes clearing up a bit. He loosened his grip but still didn’t completely let go. He just stared down at Sonic, who stared back up at him respectively.

“Sonic… Um…” Shadow’s voice was hardly above a heavy murmur, his eyes not leaving Sonic’s.

“Shads, that- fuck, that was-” He didn’t know what he’d say next, because amazing seemed… Not appropriate for the setting.   

Before he could think of what to say, Sonic was cut off by the feeling of Shadow’s other hand on his face, his thumb running over Sonic’s lower lip. 

Sonic’s breath hitched, catching somewhere in his chest. He was suddenly very aware of the fact that he was still currently laying underneath Shadow, with his legs on either side of Sonic’s hips. He was also aware of the heat emitting from Shadow’s body, and the steady rise and fall of his chest, the sweat glistening off his jet-black fur, those bloodied lips that seemed to be getting closer to Sonic’s own with every passing second-

Wait huh?
Sonic was suddenly also aware of Shadow leaning in closer, his lips only a breath away from meeting Sonic’s. He could feel Shadow’s breath against him and the only thought in his mind was more. Now. 

Shadow seemed to hesitate for a moment, and acting on pure want and impulse, he pulled Shadow forward, forcing their lips together.

In the blink of an eye, Shadow’s hesitation seemed to disappear, kissing him back so much harder. Sonic felt the energy from their fight return, and he reached up to pull Shadow’s quills, making him groan into the kiss, nipping at Sonic’s lips. 

Sonic was sure he could taste blood, and he had no way of knowing if it was Shadow’s or his own. At that moment, he couldn’t care less. The only thing he cared about currently was getting Shadow’s body as close to his as possible. The hand that wasn’t still buried in his quills came up to wrap around his neck, pulling him down closer. He felt Shadow’s lips leave his so he could kiss the underside of Sonic’s jaw. He stifled a strange noise from escaping him as he tugged harder and Shadow growled before pulling away. 

Before Sonic could protest the loss of contact, Shadow slapped him across the face. 

“Payback, since you keep pulling my damn quills.” 

Sonic stared at Shadow, a look of complete shock on his face. He could feel the lingering sting of the slap, but it had quickly begun morphing into something else. Something heavier and harder to explain. 

“Shads…” Sonic started, and before he knew it he was saying things he probably shouldn’t.

“Could you, uh- could you do that again…?” 

Shadow blinked, the slight anger in his eyes making way for confusion. 

“What?”

“Please Shadow… Just do it again.” 

He narrowed his eyes, rearing his hand back and hitting him again. 

This time Sonic couldn’t completely stifle his moan. Oh, it was obvious now. Sonic really liked when Shadow hit him. Like a lot. 

He could feel his face getting redder and was sure he was sweating profusely. Would Shadow think he was weird? Or a perv? For being oddly turned on by being slapped around by his rival? Sonic swallowed heavily.

He watched Shadow’s face carefully, watching as his expression morphed from confused to realization before smirking again, he had that same look from when he was choking Sonic out. Predatory and… Really hot. 

“Wait, what? You like that?” His voice had a teasing lilt to it and his eyes were lidded but his eyebrows remained raised. 

“You like when I hit you? C’mon, tell me.” 

Shadow returned one hand to Sonic’s throat, squeezing lightly while he used the other to slap him again, harder this time. Sonic was sure he used his claws. 

“ Shads-” 

“Say. It. Tell me you like it.” Shadow commanded as he squeezed tighter, slightly cutting into his airflow.

“ Fuck- Yes Shads, fuck, I like it…” 

“Chaos, that’s so hot… ” Sonic barely had time to react before Shadow’s lips were back on his. 

“You’re so hot, Sonic…” He murmured against his lips, panting softly. “You like it when I hurt you…”

Sonic couldn’t respond, he was too caught up in the moment. Is this what Knuckles meant by getting carried away? Because if so he understood now. Shadow’s lips were making him forget his own name. What time was it? What day was it? He couldn’t say. As much as he was enjoying this, as much as he wanted this, he needed to think. Shadow was making his brain fuzzy and it was making him want to do things he didn’t know if he was ready for, not to mention the fact that they were still laying in the grass atop some random hill. 

“S-Shads, wait a minute, hold on…” He reluctantly pushed Shadow back a little, struggling to catch his breath. “We can’t… Not right now. Not here.” 

Shadow looked annoyed but complied, pulling back slightly. He could agree that it definitely wasn’t the most ideal setting to mess around in. 

“Fine. Come back to my place.”

Sonic was seconds away from saying ‘yes please, ’ to that offer but he shook his head. “N-No, I can’t do it tonight Shadow, I’m sorry. I want to, don’t get me wrong, but this is… a lot.” He looked away in embarrassment. He wanted to let Shadow do whatever he was thinking about, to have him hit him again, but he really did need to think about some things first, not to mention the fact that the sun was starting to rise, meaning he had to be back home soon. He doubted Knuckles and Tails would be happy to find out he’d slept over at Shadow’s house. 

“Alright, I… Understand. But if I don’t get my hands on you in the next few days,” Shadow accentuated his point by tightening his grip around Sonic’s neck, pressing the tip of one gloved claw to the underside of his chin. 

“I’ll come and find you myself, and trust me, you don’t want that.”

Sonic had to use a monumental amount of effort to stop himself from whimpering at the suggestive threat. “Understood.” 

-

Sonic and Shadow went their opposite ways, their goodbyes awkward but promising. Sonic ran back to Tails’ house in a daze, his mind swirling with everything that had happened. 

He and Shadow… Made out, and probably would’ve done more if not for Sonic’s insistence. He licked his lips, tasting remnants of Shadow’s blood on them and he sighed. He was going to have a lot to think about. 

Sonic made it back to the house just as the sun fully set itself in the sky. He felt too hot, despite it being fairly cool outside. He walked through the door and was greeted again by Knuckles, still seated on the couch like he’d been before leaving out. 

“You look… Sweaty.” Knuckles remarked, taking in his disheveled appearance.

“Yeah well, sparring… You know…” Sonic couldn’t meet Knuckles’ eyes. He needed to get to his room before he made a fool of himself. “And come to think of it, I’m pretty tired, from all the… Sparring. Yeah. We’ll talk later, Knux!” 

Sonic dashed down the hallway towards his room before Knuckles could question him further. 

He collapsed in his bed, groaning as he buried his face in the pillows. His body was aching from all the fighting, and from… Something else. 

Now that he was home and in the comfort of his own bed, he could allow himself to feel all those feelings he’d tamped down in order to retain some self control.

Shadow got him real worked up, and part of him was regretting not taking that offer of going home with him. Sonic thought about Shadow on top of  him, holding Sonic down, kissing him over and over again. He groaned as he reached to touch between his legs. He could already feel his length emerging and wetness leaking from the tip. 

“S-Shads, fuck…”

He whimpered softly into his palm, gently stroking himself as he thrusted into his own hand. He imagined it was Shadow’s, that he was lying there beneath him and being forced to take it. He could almost feel Shadow’s hand around his throat still, squeezing just enough to make Sonic’s brain shut off. 

You like this? He heard Shadow’s voice echo in his head, the condescension in his voice making Sonic moan softly, even if it was just a replay of earlier. 

He imagined Shadow would hit him again, smirking as he watched Sonic stifle another moan. What else would Shadow do with him? Sonic’s mind ran wild with the possibilities; 

Shadow taking him from behind, pulling roughly at his quills and teasing him for liking it. Shadow’s mouth on his neck, those sharp fangs grazing over his pulse. Shadow’s hands on his hips, grinding them together, Sonic’s breathless whimpers and cries mixing with Shadow’s heavy groans, forcing them together.

Sonic’s hand brushed over his cheek, in the same spot Shadow had struck him and he whined, struggling to keep quiet. 

“Shadow, Shads, please, chaos, I need-” His whimpers of Shadow’s name became more incessant as his hips jerked up, he was so hard and leaking everywhere just from the memory of Shadow, how the hell would he behave when he got the real thing? He was almost there, his imagination supplying him with plenty of material to reach his peak. 

“ Fuck yes, right there right there Shads please-” He let his fingers graze over the place Shadow hit him just as he brushed over his aching tip and that was enough to push him over the edge. He moaned Shadow’s name into the palm of his hand as he came hard, messing up the fur on his stomach. 

After riding out the aftershocks and calming down a bit he sighed. Slumping back into his bed, he closed his eyes and sighed heavily. He’d come to a lot of revelations in the past few hours. 

First off, he was deeply attracted to Shadow and really liked him. A lot. Second, he wanted to have sex with Shadow as soon as possible. Third, he liked pain, specifically pain inflicted by Shadow. The more he thought about it, the more it began to make sense, the pieces clicking together in his head. 

He’d always felt a pull, something invisible that drew the two of them together, Sonic just never figured out what it was. This passion, the way they pushed each other, they were perfect rivals. Everyone would say that they were made to compete against each other, but Sonic thought they were made for each other. 

As he laid in bed, a wave of tiredness crashed over him. He’d definitely talk to Shadow tomorrow. Sonic closed his eyes, letting sleep overtake him fully. 

-

It had been two days since his… Altercation with Shadow. They had talked briefly between the time spent apart but they hadn’t met back up. 

Sonic was admittedly, a bit nervous. Not because he thought Shadow would hurt him, (at least not in any way Sonic didn’t like) but because of his own feelings. He liked Shadow, and he didn’t want to go back to being casual rivals or sparring buddies after this was all over. They hadn’t even done it yet and Sonic was already dreading the possibility of not being able to do it again. 

He’d left the house in the evening so he wouldn’t explain his reasoning for sneaking out so late at night again so soon after seeing Shadow. 

Sonic didn’t tell Shadow that he was gonna be up at the hill, but he had a feeling that he’d know anyway. Just as Sonic suspected, as he reached the top a black and red figure was already there waiting for him, arms crossed just like last time. 

“I thought you didn’t want to do this here.” 

Their interaction was eerily similar to the one from two days ago but the energy in the air was 10 times more intense, something dark and heady permeating it. 

“I don’t. But I thought we should… Talk about this first.”
Shadow stepped closer, his face now mere inches from Sonic’s. “What is there to talk about? You want this, don’t you? If we need to talk we can talk after.” 

Sonic’s eyes darted down to his lips, he wasn’t quite smirking, but his lips were turned up just slightly at the corners. 

“Of course  I want to, do you know how much I’ve been thinking about you over these past two days?” 

“Then come on, I’m getting tired of waiting.” Shadow’s voice had morphed into a half-growl as he looked pointedly down at Sonic’s  mouth. 

“Wow, who knew the ultimate lifeform was so impatient?” Sonic remarked, his voice snarky. Shadow didn’t respond, opting instead to grab Sonic’s arm and pull him closer, bringing their lips together fully. 

Despite his insistence on talking it out first, the minute he felt Shadow’s lips against his again every thought flew out of the window. He flung his arms around Shadow’s neck, kissing him harder. Shadow’s hands were around his waist, one resting right between Sonic’s back spines. He pressed into that spot harder and it elicited a muffled whine from Sonic. He used the opportunity to shove his tongue into Sonic’s mouth, deepening their kiss. Sonic pulled at Shadow’s quills again, which made Shadow push him to the ground and climb on top of him, assuming their positions from last time they were here. 

Sonic used the new angle to pull his rival closer, swinging one leg up over his waist. Shadow groaned into the kiss, squeezing Sonic’s thigh and grinding his hips forward to meet Sonic in the middle. 

The sudden movement made him shudder, their kisses becoming more open-mouthed and messy, more tongue and teeth than anything else. The little bit of sense Sonic still had was screaming at him to stop though. The location was too open, and the last thing he wanted was for someone to walk by and see this… Display.

“Shadow, w-wait, we gotta go somewhere else, what if someone sees?” Sonic’s voice was barely containing a whimper as Shadow moved from his lips to his neck, his hand still firmly placed on Sonic’s thigh. 

“Mmm, don’t care.” Shadow murmured into his neck, biting and licking at the sensitive, fur-covered skin. 

“N-No, chaos, stop…” Sonic whined, his actions not matching his words as he pulled Shadow closer, allowing him more access to his neck. 

“You’re saying stop but you’re pulling me closer. Do you really want to stop~?” He could almost feel Shadow smirking against him as he rolled his hips harder, knowing the effect it was having on Sonic’s poor psyche. Any words of protest he may have had completely died on his tongue. 

“We’re all alone up here, and I don’t intend on stopping if I don’t have to. So I’ll ask you once,” 

He punctuated his words by grinding down roughly into the sensitive crux between Sonic’s legs, making him let out a choked little moan. 

“Do you want me to stop?”

As much as Sonic should’ve said yes, to do this in the comfort of Shadow’s room, something about this scenario was very appealing to him. The idea that someone could walk by and see him getting utterly debauched by his greatest rival was doing things to him, making something hot and heavy twist in his gut. He was already in this far, he might as well see it through. Not to mention the fact that he was already so pent-up and horny he thought he would die.

“Fuck Shads- please, keep going, been thinkin’ about you all day, need you so bad-” Sonic’s inane babble was cut off by Shadow’s mouth on his. He lifted both of Sonic’s legs and threw them over his shoulders, forcing them closer together. 

“Shit- Sonic, need you too…” He grunted, his open mouth giving Sonic the perfect view of those fangs, those fangs he wished were sinking into his skin right now. He needed that violence from the night before, the aggression is what really did it for him. He gave Shadow a pleading look, his face red and his eyes half-lidded. 

“Shads, I need you to hit me again, fuck, I need you to hurt me…” Sonic begged him, pushing his hips up into Shadow’s.

Shadow’s smirk returned, he pressed Sonic’s hips back down, making him lay there and take whatever Shadow gave him. 

“Oh trust me, I didn’t forget about your little fetish. Fucking pain slut.” He sneered, leaning back to smack him again, letting his claws drag against his cheek and leaving faint red stripes across his face.

Sonic keened, high-pitched and needy. The sting of the slap along with the degradation in his tone made precum begin to leak out of his now fully unsheathed length as Shadow continued to rut against him. 

  “Yeah, you like that? Chaos, no wonder you’re always so eager to fight me. You were getting off to it, weren’t you?” Shadow paused his grinding to sit up a little. With the new angle, Sonic could see Shadow’s own hard-on as he stroked himself slowly. “It’s so hot, knowing how fucking depraved you are.” Shadow groaned, still thrusting into his hand. Sonic watched in awe as Shadow closed his eyes, losing himself in it. “Gotta get ready for you…” He mumbled, his words barely legible as he swiped his thumb over his slit, moaning as he did so. “Gonna fuck you so good…” 

Sonic now wore a smirk of his own. He had an idea of what Shadow was thinking about while he jerked himself off. He decided to tease him, bringing his leg back up to Shadow’s waist, his knee resting against his hip.

“Don’t act like you’re better than me. You’re just as much a perv as I am.” Sonic chided, his smirk growing as Shadow looked down at him, eyes narrowed. “I bet you’re thinking about it right now. I bet you’re thinking about all the ways you wanna hurt me. Isn’t that right, Shads~?” He grinned as Shadow’s movement stopped. He came back down to place his hands on either side of Sonic’s shoulders. Sonic could feel the tip of Shadow’s cock resting against his own and he had to hold back a moan. 

“Oh you don’t know the half of it.” He growled against Sonic’s ear, nipping at it roughly. “There are so many things I want to do to you, why do you think I was so fucking impatient?” He felt Shadow angle his hips so that his tip just brushed against Sonic’s hole and he wasn’t able to hold back the loud whimper that escaped his lips. 

“S-Shadow, tell me, please tell me what you wanna do…” He begged. Sonic knew he sounded so pathetically needy but he didn’t care. Not when Shadow’s red eyes were boring holes into his own, or when he felt his cock press harder against Sonic’s opening. He needed to know what was going on in Shadow’s mind, what kind of thoughts he was having. 

“Mm, I’ll mark you up so bad you won’t be able to hide it. I’ll choke you until my handprint is  bruised into your fucking neck.” Shadow began rutting against Sonic’s hole, not quite pushing in but it was enough to leave Sonic keening. 

“Gonna fuck you so hard you won’t be able to sit down for days. When you go back home, you’ll have to explain to your brothers why you can’t walk straight.” Shadow sneered, wrapping his hand back around Sonic’s neck and squeezing, determined to make good on his promise.

“We both know you wouldn’t be able to tell them the real reason. What would everyone think of their beloved hero getting fucked stupid by his rival?” His tone was taunting, and the way he was teasing made Sonic whine out in frustration. Shadow was getting him all worked up and he needed him to do it already. They’ve had days of foreplay, he needed it now. 

“ Shads- I swear, if you don’t fucking get in me now, I’m gonna lose my mind.” Sonic tried his best to sound somewhat threatening, but the whimper in his voice definitely took some of the bite out of it. 

“Now look who’s impatient.” He smirked before finally sliding in, moaning at the feeling. Sonic was so warm and tight, and Shadow could tell he was going to have a field day with him. 

“Fucking chaos- Sonic, it’s- it’s so-” Shadow didn’t have the words to describe how good it felt. He pulled out slowly before pushing all the way back in. Sonic felt like velvet around him, so soft and pliable. It was driving Shadow insane. 

“Please Shadow, more, I need you so bad…” Sonic moaned, not even bothering to try and hold back anymore. He’d never felt this good in his life, and with Shadow’s hand still squeezing his throat, he felt like he could’ve actually been in heaven. Sonic tried to push his hips up to meet Shadow’s but he pressed him back down into the grass with one rough hand. 

“No, you’re gonna stay there and take it. That’s what you wanted right?” Shadow continued to thrust in and out of him at a breakneck pace as he leaned down to kiss Sonic’s neck. Sonic felt those gorgeous fangs against his throat and he moaned again, closing his eyes and tilting his head back. His hands were clutching blades of grass between his fingers, hoping they’d keep him somewhat grounded.

“C’mon, bite me Shads, please…” He whimpered the best he could, but the words still ended up slurred. Luckily Shadow understood and latched his teeth onto the sensitive spot on Sonic’s neck. Sonic’s hands flew up to Shadow’s neck, wrapping his arms tightly around him as he whined out broken attempts at conveying how good it felt. Shadow licked over the mark before moving to nip and kiss at his chest. He sucked dark bruises onto him, so dark that they appeared even through the thick fur. He continued fucking into Sonic, Shadow’s hands forcing his hips forward to meet each rough thrust. 

“Shadow, Shadow- please I’m gonna-” Sonic whimpered, burying his face into the crux of Shadow’s neck, he could feel tears spilling from his eyes as Shadow went harder.

“Yeah? Come on, do it. Cum all over me.” His growl was back as he reached down to grab Sonic’s aching cock, jerking him off roughly. 

Sonic cried out from the overstimulation, cumming hard after only a few more seconds. It left streaks of white all over Sonic’s stomach and Shadow’s chest and hand. He stroked him through the residual shocks and only let go when Sonic weakly cried that it was too much. 

Shadow pulled out, only to flip Sonic over, draping himself over his back. 

“S-Shads…? I don’t- I don’t think I can handle another…” 

Shadow shook his head, lining himself back up with Sonic’s oversensitive hole. He smirked as he watched Sonic’s tail wag, completely giving away his feelings. “I think you can.” 

He pushed back in slowly, ruby eyes rolling back as he did so. He was just too fucking perfect, and it made Shadow want to ruin him. 

He set one hand on Sonic’s waist, gripping him hard to keep him in place. He used his other hand to pull Sonic’s quills, making his head jerk back. 

Shadow was rough, hitting that spot inside him every single time. Showing Sonic no mercy as he thrusted in over and over, every thrust being punctuated by a sharp pull to his quills. Sonic was sure he would’ve collapsed if not for Shadow holding him up. He wanted to tell Shadow how amazing he was, how good he was making him feel. But the only words he managed to muster up were choked out whimpers of Shadow’s name. 

“You’re gonna be so fucking bruised up inside…”

Shadow moaned, his thrusts beginning to stutter as he got closer to his peak. “You’re gonna feel me inside you for days, right?” He continued abusing the sensitive bundle of nerves inside of Sonic’s body, pressing against it hard every time he pushed back in. He grabbed Sonic’s face, forcing him around to face him the best he could from his position. 

“Right?”  

“Yes!” 

Sonic nearly screamed as he came again, spurting all over the grass underneath him. His knees instantly buckled, but Shadow continued holding him up, fucking into him a few more times before he was overwhelmed by his own orgasm. He moaned Sonic's name, loud and raspy on his tongue as he came deep inside of his rival. Shadow stayed buried inside of him for a few moments, allowing himself to catch his breath. He groaned as he finally pulled out, his breath still only coming in short pants. When he let go of Sonic’s waist, he fully collapsed onto the soft grass, still careful enough not to land in his own spend. 

It took them several minutes to come back to themselves after that. Sonic managed to roll over onto his back, albeit with some difficulty and stared up at Shadow.

“Shads…”

“Sonic.”

Shadow could tell that Sonic still wasn’t all there. His eyes were hazy and clouded with residual lust. Despite that, he looked at Shadow with tenderness, his bright green eyes lidded and tired but undoubtedly happy. 

“You’re incredible.”

That caught Shadow off-guard. He would’ve expected Sonic to have said that was incredible, that would’ve made sense because it was. But to say Shadow himself was incredible? He must’ve still just meant the sex. 

“I really like you, Shadow.”

“Huh?”

Shadow blushed. Sonic reached up to grab Shadow’s wrist, pulling him down next to him. “That’s what I wanted to talk about before this whole… Thing. I like you Shads, and I didn’t want to have to worry about this being a one-time thing and then we go back to acting like nothing happened.”

The lust and desire that previously darkened his expression had subsided, making way for an open honesty that made Shadow panic a little. 

“Are- you saying you want to do this again…?” He asked hesitantly. Sonic nodded, smiling sweetly at his flustered rival.

“Yeah, but not just that. To me, sex is a bonus. That isn’t what I meant when I said when I said I like you. I like you, Shads.”

Shadow looked away, his face red. How did he go from fucking Sonic’s brains out to having a heart-to-heart? Though he guessed it wasn’t very different from beating each other up before stargazing together. 

“Then why? If you claim to like me for more than the sex and fighting, why do you then?”

Sonic looked away from Shadow to look up at the sky, smiling softly. 

“You’re my perfect match. I don’t feel what I feel for you for anyone else. You test me like no one else can. But you’re gentle too, even if you don’t want to admit it.” 

Sonic giggled at Shadow's pinched expression before continuing. 

“You can be so mean, and you put up such a good fight, trying to act like that’s all you are, but it just makes the eventual reward so much sweeter.”

Shadow raised an eyebrow, confused. “What’s the reward then?”

“This.”

Sonic grinned, taking Shadow’s hand in his. 

“Getting to be with you afterwards. Whether it’s fighting or fucking, I like the way you are right now. More open, gentler.”

Shadow smirked at that, nudging Sonic’s side. “It didn’t seem like you wanted me to be gentle before…”

Sonic snorted, lightly punching Shadow in the arm. “Shut up! Yes, clearly we both know I like it when you’re rough in… That context, but I also like you like this.” He leaned over to press a kiss to Shadow’s lips. It wasn’t like the others, harsh and biting, it was softer, sweeter. He brought his hand up to caress his rival’s face before pulling back a little. 

“So… What do we do now?”

Sonic shrugged, an easygoing expression on his face. “What we’ve always done? It’ll just be a bit more fun knowing I get to have sex with you also.” He brought him in for another kiss, sighing softly against his lips. 

They stayed like that for a while, so long that the sun began to set in the sky, making way for the moon and stars. This time, Sonic wasn’t in a rush to hurry back home. He stayed wrapped in Shadow’s arms, burying his face into his soft, fluffy chest fur. 

“What’s with you and wanting me to beat you up though? That’s still fucking weird.” 

Sonic rolled his eyes, looking back up at him. 

“”Yeah, and you want to beat me up. We’re made for each other.” The deadpan made Shadow snicker. He finally went to stand up, stretching as he did so. Sonic went to join him, but quickly realized his legs were still practically useless. He almost immediately collapsed. Shadow rushed to pick him up, scooping him up in his arms. Sonic grinned at him, throwing his arms around his neck. 

“See, you’re a big sweetheart Shads~” He winked at Shadow, who gave him a look that said he was threatening to drop him. 

“Although when you said you wanted me to feel you for days, you definitely succeeded in that.” It was true. Nearly every part of Sonic’s body was aching, especially his lower half. He’d definitely be feeling it for a while, so it was good that Sonic greatly enjoyed the subtle ache. 

Shadow looked proud of himself, holding Sonic a bit closer. 

“So where do you want me to take you? I don’t know how your brothers would feel about me showing up carrying you like we’re newlyweds.”

Sonic groaned, just thinking about their reaction was giving him a headache. “Yeah, they’d throw a fit. How about we go back to your place? At least then I can deal with the fit once I’ve rested.” Shadow nodded, not questioning him at all. He activated his boots and took off towards his home without another word.

Sonic nuzzled against him, breathing him in. As they made their way to Shadow’s home, he looked up to see a trace of a smile playing on his rival’s lips. He realized soon after that it matched the one upon his own.
