It started out like a normal sunny day.

Sonic the Hedgehog, Mobius’ hero in blue saving the day by bashing bots built by Eggman. Then defeating him before grabbing some of his favorite chili dogs. All before stopping by to see his closest friends and fox brother. Running errands and doing some personal shopping was nothing out of the ordinary either before going back home. Today was a regular, average, day.

Yet, something changed that evening. Instead of a smiling hero, waving to his kind fans? His hands were up to no good.

Now ‘Sonic the hero’ was slumped over in the kitchen; propped against the wall. Legs shaking from how hard he was fucking himself on his fingers with his dick dripping. Even when biting his lip, drool and sweat fell to tiled floors. His ears were pressed against his skull in submission, body shaking from the stimulation. The pressure in his gut made his knees weak and limbs feel like jelly.

“Chaos–” The hero gasped, curling his fingers at a different angle. His eyes were shut tightly, hand stroking his dick in tandem. Even with all the friction nothing seemed to soothe him. A part of him was trying to deal with this stupid issue himself but time was wearing thin. Something inside him was bubbling over and he knew what he wanted.

More importantly, who he needed.

The phone, a landline, was in eyesight. With one call Sonic could get the situation under control but a part of him didn’t want to bother Shadow. He still had no idea what brought this up. Having no clue why his body felt like it was on fire made it worse, sure he got horny sometimes but this was pure lust. He wanted to be fucked now and it scared him.

Trying to keep his composure and dignity, the blue hedgehog dragged his feet to the phone. Thanking his lucky stars Shadow was on speed dial he clicked a few buttons and lifted the device to his ears. He was still panting softly, sweat collecting on his brows. The long rings felt like hours as he waited around until a click was heard. “Sh–Shadow?” He sputters, body spasming. 

“Sonic?” A gruff and grainy voice rang through. “What is it? I’m busy.” Shuffling and papers moving around on the other end could be heard. It seemed like the older male was in his office, probably finishing up some G.U.N paperwork at this time.

“I uh–” The hero stopped, not wanting to bother the other for his weird fetishes. He bit his lip to ponder on what to do. Maybe he should just do this on his own?

After stopping what he was doing, Shadow could hear the other’s ragged breath. Something was off about this situation, Sonic almost never rang him at work. “Are you in trouble? Do you need me?” He asked.

Chaos do I. I need you so fucking badly. “Yes.” He whispered softly, feeling guilty for it.

Shadow packed up his stuff in an instant before pulling out a green emerald. The gem sparkled and glistened in his hand, ready for use. “Where are you?” He questioned before exiting his office, walking out the door. His shoes hit the tiled floor hard, since they didn’t allow him to skate inside.

“House. Hurry…” Sonic gasped desperately as he sunk his fingers into himself. Instantly the phone went dead, and he let it fall to the ground. A dead line could be heard but he didn’t have the heart anymore. All his strength went to his legs to keep from ending up on the floor. The hero was gripping the countertop, brain foggy from the heat. He was aware of a ‘zap’ that came from the house, but where it came from he had no clue.

“Faker, where are you?” Shadow shouted as he followed the breathing. He heard it coming from the kitchen so he headed there, preparing for a fight. After turning the corner an abrupt scene halted everything that was going on. Shock filled all of his senses as his eyes laid upon his lover, cock out in the kitchen looking like a mess. The smell of sex filled his senses making it hard to focus; objects littered on the floor.

“Shadow! Please.” Sonic begged, body instantly gravitating to his lover. He crashed into a solid body before gripping white chest fur to keep him up. Strong arms wrapped around his waist to hold him there and he leaned into them.

“Damnit, Sonic. What the fuck is going on with you?” Shadow huffed, trying to wrap his mind around what the hell was going on.

“I don’t know. I–” The hero swallowed hard, trying to pinpoint the exact moment he started to feel like a whore. “I need you baby. Please do whatever you want to me.” 

Shadow was still in shock at all this. The words were going right to his groin, unable to be processed properly. He had never seen his lover like this before; so needy and dripping. It was quite arousing to see. The way Sonic begged for his cock to be inside him lit a fire he never knew he had. But if anyone found out he left work early for sex? He’d be dead.

Sonic guided his boyfriend to the dining room. Swaying his hips a little bit more than usual it became an invitation. He knew his lover was watching them, like always. A blue body turned towards a dark one, back against the wooden table. Instantly Sonic cupped his lover's muzzle to pull him in.

“Honey–” Shadow said against soft lips, hoping to stop this before it got too heated.

“Mhm?” Blue hummed as he kissed down a strong shoulder.

“Shouldn’t we figure out what's going on with you?”

“What?” Sonic whispered against his lover’s ear. “You don’t want me, babe?” He pouted playfully.

Shadow sighed deeply. “That’s not it, love.”

“Then touch me,” Sonic cooed. His ungloved hand guided a striped one to his waist. Placing his own over it, their eyes met in challenge. They both knew what was going to happen if someone didn’t put their foot down. Things always ended in Chaos, with the room being an accessory by the end of it. Most things broke around them when fucking, with this time being no acception.

Shadow let out a defeated grunt, knowing there was no way to deny it. His weakness was his lover; everything about him. From his sense of humor, down to the twitch of his nose when he hated something. He had fallen in love with him entirely which made the world sway his way most times. Shadow had yet to deny his boyfriend a kiss let alone sex.

Pulling a blue body into him Shadow got to work. Turning his lover around, he got behind the other and waited. Sonic was busy swiping napkins and placemats off the table before bending over it. Since he had already fingered himself, he was ready for it all. There was no need for prep since he was already dripping.

Shadow unsheathed himself and spat on his hand. Giving himself a few tugs, he watched his cock pulse. It was thick and long with a large knot at the beginning. After a while of not having sex it became swollen, but he had a feeling it wouldn't last much longer. The color was a fade from black to red with 5 ridges to divide up the sections. A slightly tipped end made it easier to fit inside his lover.

“Ready, love?” Shadow asked in a sultry sweet voice.

“Yes.” Sonic practically begged.

The older male placed the tip at the entrance. Watching the head pop in, he heard his lover let out a satisfied moan. His hips pushed farther as one hand held a blue hip, still watching his cock sink inside body. Gritting his teeth at the sensation around him it became a lot easier than usual and he slid right in; all the way to the hilt.

“ Chaos– ” Blue groaned as his eyes slid shut. The fill felt so fucking good with his body tingling and fingertips gripping the table.

“Damn Sonic.” Shadow grunted, still a bit shocked he was able to push all the way. He was able to slide back just as easy, pulling half way out just to snap forwards again. A loud moan rang through his ears making his arousal kick into over drive. He didn’t care anymore and started at a nice pace, enjoying the feeling at first. 

Yet a few minutes later the older male was setting a vicious pace. Rocking the entire table, lewd wet sounds filled the air. The view in front of him was the best, Sonic’s ass against his knot, body taught and curvy, all while moaning his name. It only made him want to drive in further and hit that sweet spot; when he went deep.

“Harder Shads!” Sonic gasped, before an arm was pulled back. A little confused he allowed the striped hedgehog to get a good grip on his wrist.

Shadow squeezed the other before pulling his cock out until the head. All before yanking backwards, and snapping his hips forwards. Forcing the blue body to arch off the table, Sonic’s ass hiked back in an instant. All at once his cock plunged into his boyfriend, pushing until the knot.

Sonic cried out, eyes open in shock. Almost choking on the air in his lungs, he felt his stomach jut out at the plunge. The hand on his hip snaked around to his neck to pull him back, forcing his eyes to look at fiery ruby red irises. His ears laid flat against his head at the pressure in his stomach.

Shadow kept fucking into the hero, giving him exactly what he wanted. One hand now drew an arm back, while the other wrapped around a blue throat. It forced a blue behind to push forwards, making the knot slam against the entrance. After all the years of pleasure, the knot was never able to fit inside. For it was too big for Sonic.

Drool dribbled down the hero’s chin. Loving the treatment he was getting, his guts were driven into. Heat flooded his face and sweat fell from his brow. He didn’t care about how loud he was, he just wanted to be used like a fucking toy.

Leaning over his lover, Shadow nipped at a blue ear. His chin rested against a blue shoulder as he stayed still. “My pretty boy,” he cooed.

Sonic swallowed, hard, at that. The nicknames his lover gave him during sex became a weakness over time. Holding still almost made him lose it. The arms that held him up were shaking from overstimulation, but he held firm, not wanting this to end. Blue knew he had to be good to get what he wanted.

“So messy,” Shadow growled before swiping at Sonic’s bottom lip.

“My pretty doll.” The older male smiled.

“Fuck me, Shadow.” Sonic tried. “Please don’t keep me waiting.” He begged before he was turned to the side. A blue leg was thrown over a dark shoulder, making his body to twist, showing everything between his legs clearly to his boyfriend. It forced a flush to fill his cheeks at such an open position.

“I like this view.” Shadow hummed, looking at the connection point.

“Push your knot into me, Shads. Come on baby.” Sonic asked, not caring about the many times before. He could see the wheels turning in the striped male's head. They both wanted this to happen, of course. Determination was one thing but lacking all regards for what his body could handle was the issue.

“It’s not gonna–”

“ Make it fit. ” Sonic growled, ears going back after losing his patience. He wanted to feel that stretch but his stupid body wouldn’t allow it. There had been times they’d prepped beforehand too. So maybe this time would be different from how slick the hero was.

“We can try.” Shadow slowly inched his way out a bit, careful not to hurt his lover. Giving just enough room so he could spit right on his knot.

Sonic bit his lip at the anticipation, hands curling under him. Knowing it might not fit this time either made it hard to think clearly. He had never known the feeling of being stretched to the max. Even with Shadow’s dick being larger in size, he knew he could take more. He just hoped he wouldn’t split in two, though it would be one hell of a way to go out.

“I’m gonna go slow.” Shadow said before getting himself ready. His thumbs pulled Sonic’s opening apart, forcing it to stretch more. A hiss through the room could be heard as he bottomed out, knot fitting against the hole. It swelled and twitched ready to be buried inside. He wouldn’t admit it but he had fantasized about this moment.

“Please–”

Slap!

A harsh hand went over a blue ass cheek, forcing the hero to become silent. “Wait.” Shadow snapped harshly, getting annoyed at the impatience. “We go at my pace.” He knew if he didn’t lay the ground rules, his boyfriend would hurt himself. It was his responsibility to take things slowly and as carefully as he could.

Sonic felt the push against him; taking a breath to relax his muscles it still wasn’t going in. It frustrated the younger male.

“I don’t know–”

“I'll be alright.” Sonic whined as Shadow grunted.

Slowly rocking his hips, Shadow keeps his lover's ass spread. His ears went back as the pressure slowly started to build and he applied more. Bucking his hips forward to try and push it in. Soft whines filled the air before–

Pop!

Sonic let out the loudest moan he had ever made as the knot popped inside him like a lollipop. Tears streamed down his face at the stretch and pain he felt. Finally , after so many times it was able to slide in. His gut felt so full with a bump protruding from his belly. Everything in the room started spinning as it fit snugly inside.

“Chaos.” Shadow hissed, feeling the squeeze. The warmth made him curl over his lover; knees giving out.

“Sh–Shads–” Sonic tried as his ear was bitten. A hand slid to his own and he squeezed it, trying to hold onto reality. The solid body rested over his back allowing the knot deeper. As they rocked their hips a blue leg pushed back more, making the hero grateful for his flexibility. 

“Damnit.” The older male growled, teeth still nipping at a blue ear. It took everything in his strength not to move, he knew the other needed to adjust to such a large intrusion. Let alone taking it all for the first time, with only minimal prep and spit.

Shadow heard his boyfriend take deep breaths, and stalled. Getting curious, his hand slowly wrapped around a blue hip. Moving it towards the shockingly pudgy belly, he cupped it gently. Sonic let out a small groan as he began to massage the fur. Thumb running circles as he enjoyed the bulge; a bit too much.

Sonic’s eyes were closed as his body relaxed, tears still coming. His breath was ragged and quills unkempt. The weight inside him was unexplainable. With the stretch feeling less painful with every passing moment, pleasure ran through his system. Extending from his toes to the tip of his ears.

“Think you can take a good fuck?” Shadow grinned, slyly giving the bulge a squeeze. His lover was of course unable to respond, too stuffed to process the question.

Sonic only nodded, happily numb.

“Very good,” Shadow complimented before standing up fully. Spitting on the connection once more he started all over again. Only this time with his knot popping in and out. Long stroking his way through, wet sounds and grunts filled the house as the hero was fucked into.

After a while Sonic’s stomach started to feel weighty, body pushed to the extremes. His guts were slammed into each time the knot fit inside him, pushing past the bundle of nerves. Drool, tears, and sweat ruined his face making the world blurry but he didn’t care. He was right where he wanted to be, too blissed to be damned.

Shadow gasped as a particular squeeze made him falter. Sonic’s body had been molded to fit him, forcing some maternal instincts to kick in. Oh how he wanted to fill his lover with pups and keep his stomach swollen. How nice would it be for everyone to know what they did. That their beloved heroic hero got creampied. 

“Shad–I can’t–” The hero gaped. The intensity he was feeling was starting to get euphoric, nails scratching at the table. His toes curled whenever his boyfriend bottomed out, making the release inch closer. White dots spotted his vision, and he knew things wouldn’t last much longer like this.

Shadow picked up on the hint, turning Sonic on his back. With both legs on his shoulders, he was able to see the hero’s face. Such beautiful features, blue brows furrowed in pleasure, hands fisted on the table, with moans leaving a messy mouth. The older male didn't think he could love Sonic any more than he did at this moment.

Black striped arms imprisoned blue to the table as their eyes met. All Sonic could see was his boyfriend, the perfect view. Reaching out, their bodies met in an embrace. Cheek to cheek, skin to soul, nothing could get in the way. Sharing a moment made for them, they shared the pleasure made between them. 

“Inside?” Shadow asked, out of breath. He felt the other nod against him, too blissed out for words. And after a few more thrusts the spiral in his knot began to uncurl, ready to be released after all that time.

“Gonna–” The hero tried before he was gripped tighter.

“Cum for me baby.” Shadow whispered, before gutting his lover. Cock hitting so deep inside the other, it punched out whatever was left.

“Ahn–Shadow!” Sonic cried, moaning out the other’s name like a prayer. His body curled inwards and jolted, fireworks going off in his brain. Everything became too deep and too much before his own cock sputtered between them. Ropes of cum ruined his fur and tears of pleasure fell down his face. Hot flashes ran through him as the orgasmed raked through every nerve, knees squeezing the body between them.

Shadow held onto his boyfriend for the last time before his cock was held hostage. The squeeze stopped all movements and he couldn’t hold back either. With a grunt of his own, release came with the knot sitting inside. Pump after pump cum filled his lover. His dick gushed and lurched, warmth flooding over it. Chaos energy flowed through him, zapping his fingertips almost making him fall. 

Sonic’s eyes rolled back as soon as he got his wish. He felt the knot shrink inside him as hot cum filled him like a cream stick. His belly swelled to accommodate everything, pushing tension against his prostate. It felt exhilarating to be claimed in such an intense way, and he reveled in the after glow.

Both hedgehogs gasped for air, arms still around each other. The table creaked under the weight of them. The room was hot and heavy, things still on the floor.

“Are you ok?” Shadow spoke up, looking down at Sonic.

The hero nodded numbly, still in a daze.

The older male chuckled before pulling himself out. “You liked that, huh?” He asked. Keeping blue thighs open he watched the gush of seed that followed. His ruby eyes gleamed at the sight, happy that he got to see this side of the hero. No one else would be able to and he revelled in that fact the most.

Sonic’s legs ached and spasmed after everything. He was barely able to keep his legs apart, with all his strength going to his breath. He felt like jelly while his stomach deflated, pressure lessening. There was no way he could care about the mess he was making either, the only thing on his mind was Shadow.

“So pretty,” Shadow hummed before a finger teased the swollen hole.

“Mngh, Shadow wha–Ah!” Sonic gasped and arched off the table when two fingers plunged inside him. Overstimulation kicked into overdrive as the digits curled inside him, pushing deeper until the knuckle forcing out another moan. The white dots were back again too, making it hard to focus.

Shadow’s ruby eyes gleamed at the sight, cleaning out his lover in such an inappropriate way. Yet a part of him liked to watch the blue male writhe under him, by his fingers fucking into an abused hole. So he took his time and added a third finger just for fun and to hear those beautiful sounds again.

Tears fell down the hero’s cheeks as his claws dug into the table. Everything fell onto the floor beneath them, soiling the wood. Only when the digits retracted was he able to breathe again, body thumping on the table after being officially spent.

Shadow stood up and wiped the sweat from his brow. Tucking himself away he started helping the other male. Making Sonic sit up on the table, they made their way to the bathroom. With the older male carrying the hero bridal style.

“That was amazing.” Sonic mumbled, smiling softly.

“It was.” Shadow agreed, legs slightly wobbly as well. “But I did mess you up pretty bad.” He confessed.

“And I love you for it.”

The Ultimate Lifeform let out a hearty laugh, knowing this wasn’t going to be the last time. “I love you too, Sonic.” He nuzzled into the other whose eyes had slipped closed. Taking the time to give the other the best aftercare, the two got into bed and fell asleep almost instantly after that.

Not caring about anything else but them.
