Chapter Text

The feeling of cold metal cuffs biting into pulled taut skin was a sensation Knuckles least expected when awakening. His head felt packed to the brim with itchy cotton and his mouth full of sticky peanut butter. With a groan, he attempted to pull a hand down to rub his face– only to hear a chain clink and feel a harsh tug. “Whh… whuh…?” He blinked light– what little there was to be had– into his eyes, and noticed, with horror, where he was– a dungeon. The dungeon was a harrowing and imposing place, Knuckles was kneeling in an uncomfortable position, his back arched and his wrists and neck pulled back and up. The only light was a single dim red torch, highlighting the thin sheen of sweat on the warrior’s prominently muscular body. The clanking and straining of the chains echoed against the impenetrable brick walls. Then, it all came rushing back to him. He was in the burning Angel Island, desperately defending Tails with every last bit of his energy– and yet something– someone– defeated him, knocked him out. But who?! And what had happened to Tails?! 

Knuckles growled and anger began to boil in his chest as he tugged against the heavy chains, his thick biceps straining as he pulled with all his might… and yet they did not budge. The red-quilled echidna bared his teeth, yanking and pulling with all his might against the black steel chain cuffs that bound his wrists and neck, his broad chest heaving with every labored breath. He hated this so much, the feeling of being powerless and weak was unimaginably humiliating. Just then, his ears picked up a chuckle behind him. It sounded like… Sonic?! “Sonic, is that you? Come help me, I’m stuck!” He called out, expecting the blue hedgehog to come and break him out… only to be greeted with something or someone that made his heart drop. 

“What a pitiful sight.” the voice mocking Sonic sneered. Much to Knuckles’s horror, into view came none other than Sonic.EXE himself. He stared down at Knuckles, holding his face in his gloved hand. His red eyes with black sclerae peered into his soul. “You think you can stand a chance against me, echidna? Such foolishness.” Knuckles flared with anger and attempted to yank his head free. “What the FUCK are you doing?! What did you do to Tails?! You bastard, let me go NOW or I’ll pulverize your ass into a pulp.” he shouted, yanking forward and snarling at him. This didn’t trigger a single fear response in EXE, who only laughed, that same mocking laugh. “Well now, that’s no way to talk to your new master. Tails is fine, he’s in suspended animation in Ice Cap and is… mostly unscathed. You on the other hand…” He trailed off and allowed a single finger to run down Knux’s chiseled chest and stomach, feeling every tic and pulse under his pointer finger. “I can’t let you go so easily. I have no use to get out of Tails but you… you could be very useful to me, Knuckles.” The chains tightened again as Knuckles tried to push the Void king’s hand away from him with his shoulder.  

“Get your hands off of me, you sick fuck!” He snapped, the anger still boiling inside of him. “What are you going to do to me?!” he demanded, his voice full of fury and just a pinch of fear. EXE only walked behind him, letting the question hang in the air, and allowed his chin to rest on the bound male’s shoulder, pressing his chest flush against his back. “I can see why Rouge fancies you so much,” the king said breathily into Knuckles’s ear, getting him to shudder at the feeling of his hot breath fanning against the side of his face… he had to resist biting down into his firm shoulder. “You’re quite the handsome echidna.” 

“D-Don’t you dare talk about her. I’m not into men so don’t try your chances with me.” He said with a faux smug air. EXE tutted at that, feigning disappointment, this time running an open palm over his captive’s abs, feeling the valleys and ridges of his toned body, as if he was savoring every inch. 2 hands slid up and cupped his sturdy pecs, subtly squeezing his nipples between his thumb and forefinger, absolutely savoring in the sharp inhale Knuckles took and the feeling of the 2 buds hardening under his fingers. “Oh, such a shame.” His hand began to trail uncomfortably lower, tracing idly over his pelvis and hipbones and right over his happy trail. Knuckles felt his skin prickle everywhere his gloved hand made contact. “I was getting to like you…” The hand settled on his thigh, feeling the dense flesh and squeezing it ever so slightly, sensing every little jolt and twitch. EXE grabbed the side of Knuckles’s head and pulled it to the side, exposed his neck, allowed his mouth to open then slid his long, black tongue along his neck, tasting his sweat and leaving a trail of hot saliva in his wake. The feeling of his new toy shuddering in disgust was invigorating. “Too bad that I get what I want when I want.” He settled his hand onto his groin, ever so subtly pressing a finger down, and Knuckles almost immediately jerked back. “DON’T FUCKING TOUCH ME!!” he screamed, his rage flaring up. EXE laughed mockingly, rubbing over his thighs once more, not taking him seriously in the slightest. “So feisty,” he commented. “You’re gonna be so fun to break down.” The hands began to knead slowly at his inner thighs, the feeling of the firm muscles twitching almost in protest entertaining the twisted King greatly. “So much muscle, so much raw power… and yet you can’t even break these chains. How utterly pathetic.”

 Knuckles’s knees dug into the floor of the dungeon as he struggled to pull away from the Void King. “Go to hell! I’ll never submit to you, I’m stronger than you and you know it.” EXE’s mocking demeanor dropped, he stood up and walked in front of Knuckles, grabbing his face harshly. “I don’t think you understand who you are up against, echidna. I control everything about this dimension, including you. Every breath you take is at my discretion.” His eyes widened, and fear began to sink in. 

“Your strength means nothing to me. I own every part of you— You. Are. My. Property. So you would be wise to listen to me and obey me unless you want to end up like Eggman and be erased from every plane of reality.” Knuckles felt his stomach drop to his tail. EXE was… right. 

Just as he was turning this over in his head, he felt the chains on his wrists begin to tighten. 

Painfully. 

“You’re in my world now, Knuckles. I will have lots of fun seeing how far I can push your limits.” They got tighter. Knuckles sucked in air through his sharp teeth, his strength draining from him as he tried desperately to dislodge his hands. When it felt like they would snap his wrists, he screamed. “Fuck, FUCK!!” The king only smiled at the display, watching the powerful Mobian thrash and scream like an animal with its leg caught in a trap. “You can either submit willingly… or I can break your will and make you submit. Your only purpose here is to kneel and entertain me” The chains tightened again and Knuckles’s screams of agony reverberated off of the walls of the dungeon. EXE smiled as he observed the spectacle, the tortured echidna bit the inside of his cheek to stop his screams, and his mouth filled with the metallic taste of blood. “Beg. Beg for me to stop tightening the chains and I’ll consider stopping.” It wasn’t a question– it was a command. Knuckles refused to let EXE win, the flame of defiance still burned within him and he refused to go down without a fight.

 “Fhhh—F-fuck you! I’d rather die than beg for mercy from y-ACK!” They tightened again when he cursed, while he continued ignoring his wrists feeling like molten glass. EXE growled. “That’s not the answer I’m looking for.” His grip on his captive’s face tightened, and so did the chain around his neck.

 “I’m not asking.” 

Knuckles felt himself growing lightheaded. 

“Beg.”

 He was losing feeling in his hands.

 “Now.” 

As the last of his breath began to fade, he coughed out, “Pl-please— please stop tightening the chains, please don’t make them constrict so hard—I’ll obey, just don’t ch-choke me–,” EXE smiled and just watched as his captive squirmed. Just as his vision began to go dark, the cuffs slacked and returned to their normal state, Knuckles sucked in air desperately, his chest heaving and the feeling returning to his hands, swallowing down his pride. A satisfied smile crept onto EXE’s face. “Good. Now we can begin your training.” 

Knuckles could only pray that Tails would be okay.

No time was wasted. EXE placed his hands on the chains binding Knuckles, and the shackles on his wrists fell away, but the one on his neck did not. This was his chance! He braced himself against the ground like a track star and charged at EXE, ready to make the bastard pay for everything— only to feel a searing pain in his neck. A loud shriek of pain tore from his throat as his hands flew up to claw at the chain around his neck, only to yank away when they felt the searing metal burning into the skin on his neck. He screamed with pain, and EXE simply smirked at the sight. “Do you know what temperature of metal is fatal if exposed for long enough?” He asked offhandedly, standing over his writhing captive, as if expecting an answer. “Sixty degrees Celsius. Right now, that cuff is about, say… 55 degrees.” Knuckles writhed desperately, shrieking in agony, clawing at the shackle so violently he left scars on his own skin. Tears began to stream down his face, evaporating in steamy clouds when they dropped onto the chain. The smell of burning quills and flesh singed his nose.

“I think we both know what you need to do.” EXE said, walking to Knuckles. He tried once more to take a swing at him— only for his strong arms to be suddenly bound behind him, in a very harsh reverse prayer. So harsh, his palms were forcefully facing each other and tied together. The rope dug into his body, EXE almost got distracted by the sight of the black rope complementing his sweaty, chiseled form. “Submit. Submit to me in your entirety and I’ll stop.” Through his screams, Knuckles forced out— “O-okay, I submit! I SUBMIT!! PLEASE JUST MAKE IT STOP!!!” EXE stood there motionless, just smiling down at his slave and watching him writhe in pain as if testing him, then snapped his fingers and returned the chain’s temperature back to normal. “There. That wasn’t so hard, now, was it?~” the king cooed, not expecting or really needing an answer. “Now we can start your training fully.” Knuckles breathed a sigh of relief, hoping the chain on his neck would go.

 Instead, EXE reformed it— into a collar. The metal stayed around Knuckles’s neck, but this time the chain was held by his new master. His neck was stinging horribly. A growl left his mouth, but this only got a smile from the king. 

“You look so cute like this.” he murmured, allowing a thumb to rub over his cheek. “Well, come along now. You aren’t gonna become a good pet just from being chained up in here, are you? Come on.” With a tug to the leash, Knuckles reluctantly rose to his feet— only for a hand at his shoulder to stop him. “What are you—“ “Ah ah ah. You’re a pet.” Knuckles glared at him, and resisted, pushing in his knees and trying to stand— but this didn’t last. He felt rope being bound again, this time frogtying his muscular thighs, forcing his legs to fully bend. Now he could hardly use anything, his shoulders were aching from the reverse-prayer. “Pets crawl.” EXE got up, allowing the chain to lengthen, and walked away briefly. Just then, Knuckles felt the ground and air around him shift. 

The dungeon faded and fell away, now they were in the throne room. It was a long hallway, noticeably better lit with blood-red torches lining the walls in perfect straightness. The floor was just barely smoother and was gentler on the echidna’s knees, yet the walls were made out of the same black stone material of the dungeon. And, the centerpiece, the main attraction— the throne. It was a massive thing, its frame was black onyx and obsidian, a bright red gemstone with an X and a dot at the bottom of it sat at the top of the throne, framed in gold. The seat of the throne was lined with angelic platinum, and the cushion was red silk. EXE was sat comfortably in his rightful place, smirking across the hallway at his bound captive. “Come.” 

Knuckles’s eyes widened, he looked at the King with eyes full of anger and disgust… though he would be lying if he said he didn’t feel the slightest, barest stirring in his loins. “Y-you’re craz—hng!!” His scoff was cut off by a sharp tug on the collar. “I’m not asking. Come, crawl to your king and grovel at my feet.” With a huff, the bound warrior began to shuffle forward, due to him not being able to crawl with his elbows he could only move his knees and pull himself forward slightly. This displeased his king, who gave the leash another tug, making Knuckles stifle a gasp at the feeling of it pressing against the still-tender flesh of his neck. “Crawl faster.” He tugged just a bit harder which sent the echidna onto his chest. He huffed and began to push himself forward, crawling on his chest and knees. He had to be careful— every little movement made his heavily bound arms sting and his legs ache. 

EXE chuckled breathily at the sight. “You look ridiculous like this.” He commented, and Knuckles huffed, continuing to squirm along the floor. The king continued, “All that raw muscle and you can’t even save yourself. It’s funny how even the strongest fighters can learn their place so quickly with some torture.”, and the echidna continued on. His face burned with humiliation, and so did the rest of his body… god, that reverse prayer hurt.  He tried to at least pick up the pace, but as he did, he caught sight of several… things laying around, he couldn’t help but slow briefly and stare at them. One of them was a red ball with 2 leather straps… one was a string of golden beads that tapered at the end… there was a good collection of love eggs, clamps… oh God. With every item, Knuckles felt the fear and revulsion in his stomach deepen. But what could he do? Try and fight EXE? He couldn’t ignore the ever so slight stirring in his gut at the thought of him getting… He was pulled out of that train of thought by another tug. “Hurry on now, pet.” The king’s voice was sickeningly sweet. 

Knuckles pushed in his knees and crawled just barely faster. Small puffs of breath left his mouth, he forgot how weird the temperature of the room was. It was warm, and yet very humid, making the sweat painting his body ever more obvious. His neck was beginning to feel just slightly better, though he knew that the scarring may be permanent. And he also knew that was definitely intentional on EXE’s part. He continued to struggle and crawl along, the rope leaving indentations in his skin. He felt utterly humiliated. He was Knuckles, guardian of the Master Emerald and survived the echidna extinction with only a few pods of survivors— and this is where he was? Being a torture slave for a sadistic king? His mind went back to Tails. Oh God, please be okay. He hoped that he was safe (as safe could be) in suspended animation, and at the very least EXE wasn’t giving him nightmares or something. The sight of… everything made the slight tingle ever more obvious for Knuckles.

EXE couldn’t really hide the stirring in his loins either. He had taken a liking to Knuckles long before he decided to raid his world. Who wouldn’t? Even the straightest man could appreciate such powerful muscle, such amazing strength… and how fun it would be to see him break and become the dumb babbling himbo he was always meant to be. He had to put forth quite a lot of willpower to resist tying him down and ravaging him right away. There had to be pacing— make him sink into it. EXE knew himself to have a ‘bit’ of a sadist streak.

Finally, Knuckles made it, glowering up at his king while perched in front of his throne. EXE couldn’t hide slightly biting his lip with his sharp teeth, the sight unimaginably arousing for the Void king. He reached down, patting the top of his head with his gloved hand. “Good job, pet! You have pleased your king.” Knuckles growled slightly at that. “Now, down you go.” A look of confusion flashed across his face. “What do you—“ “Clean my shoes with your tongue, echidna.” EXE said that like it was just an offhanded statement. But the fear of being burnt or choked again…

Knuckles reluctantly lowered down, and lapped his tongue against his shoes. He gagged a bit in response. Thankfully, they weren’t horribly grimy, but they definitely weren’t clean. “Mmm, good boy. Clean them good for your master.” His tongue dragged along the material, his face burning with humiliation once more as he licked and cleaned. He felt something pressing his head down into it— EXE had lifted his leg and pushed his head down, keeping him in a submissive position. He had almost forgotten his body straining from the tight bondage. “You’re supposed to be powerful, yet here you are, scuffing my floor with that big, dumb body of yours." And he was… right. Just then, he felt a tap on his shoulder and looked up the best he could— when did EXE grab a riding crop? “Lick slower, take it seriously.” He critiqued. “I want those spotless by the time you’re done. I’m sure you don’t want to feel this-“ He pressed the crop against his back- “on your backside.” 

Knuckles huffed, growling again but kept licking. He didn’t stop giving EXE a death stare at any point, which only prompted a chuckle from the king. The leash began to lose its slack, he was winding it slowly around his hand. Finally, that ordeal was done and EXE pulled him by the leash so he was seated directly between his legs, looking up at him. The sight was unimaginably arousing for him. The echidna was struggling mentally, EXE just barely resembled Sonic. And, he’d had many… fantasies of his friend before. Thoughts that he allowed to let run on just a little longer. 

But that was just his mind, right? 

Straight guys fantasize about their friend all the time…

 right…? 

EXE cupped his cheek, running his thumb along the side of his face as if he was observing him. Just to tease him, he gently pressed a foot against his crotch slit, sending a jolt of pleasure up his spine. “Hnnf—“ he huffed. “Your legs look lovely when they’re spread.” The dark king teased. Knuckles was about to growl again, but suddenly felt his face being held. “I think you’ve growled quite enough, pet.” He said. “Open your mouth.” With reluctance, he just barely parted his lips, only for EXE to press his thumb against his thumb and pry his mouth open. “Good boy.” Out of nowhere, he leaned down, opened his mouth, and spat down Knuckles’s mouth. He gagged with disgust and revulsion, making EXE giggle. He quickly closed his mouth before he could reject the ‘gift’. “Swallow.” He commanded softly

. 

And, along with his pride, Knuckles swallowed.. “Cute.” Just to make his humiliation worsen, he formed something— a bit gag. He held his captive’s head still and reppened his mouth as he pressed the gag past his teeth and fastened it behind his head. Knuckles huffed, his teeth sinking into the material and his speech garbled. “You look adorable like this.” He cooed sweetly, tangling his fingers in his quills and stroking them like a dog. “Well, now… I think we both know what you need to do now.” 

He stood up, and Knuckles felt the scene around him shift once again- this was a large, opulent bedroom. It had black carpet and dark red painted walls. There were paintings of tortured Flickies, Tails being chased, Eggman mutilated, and plenty more. Everything was either black or red, and was always intricately detailed.

The bed was massive, it had a four-poster frame with black silk acting as a curtain. It was furnished with red pillows and a thick black comforter. But the thing that drew Knuckles’s eyes the fastest…

Were the 7 Chaos Emeralds embedded in a display above the bed. 

Oh God. Oh God he had the emeralds. 

EXE snapped his fingers next to Knuckles’s head. “Ahem.” He said calmly, and he brought his focus back to his king. “There now. I believe you and I have some business we need to attend to.” A smirk crept onto EXE’s face. Knuckles dug in his knees the best he could, but he couldn’t really get anywhere with the position he was in. This only got a breathy laugh from his king, who began to wind his leash up again.

“Come to your master, Knuxy~”

That’s when he knew he was in for a long, painful night.

Chapter Text

The first order of business was EXE pressing a finger to the bit gag in his captive’s mouth, and reshaping it into a metal ring. The new ring gag forced Knuckles’s mouth open, his tongue hanging out weakly. A string of drool slowly slid down his chin, onto the floor beneath him. He glared up at EXE, tugging on the tight bondage continuing to keep his arms in the brutal reverse prayer. “Ang ‘unna ‘uck ou ah!” He tried to threaten, even with his speech now obstructed to a humiliating degree. 

Of course, this amused his master greatly, who smiled condescendingly down at him and stroked his head. “Silly boy. You don’t need your mouth for communicating. And you know you need it, I don’t need my dick bitten off.” He taunted, beginning to tug Knuckles closer and closer to the space between his legs. “Your mouth…” He reached down between his legs and began to rub the unassuming slit. “Should only be used for pleasuring me.” Knuckles watched in horror and mounting arousal as the cockhead peeked out of the slit… then began to emerge. 

He couldn’t keep his eyes off of it. The king’s phallus was long and tentacle-like, tapering off at the end. It was an inky black, and was secreting a red substance that was glowing slightly. It just kept emerging as EXE lazily stroked it, swiping his thumb over the tip, massaging the base, fondling his balls… 

Wait, what was he doing?! EXE chuckled at Knuckles’s eyes fixated on his cock, even more strings of drool had slid from his mouth and his pupils were ever so slightly dilated. Teasingly, he asked, “Oh my… you liking the show, echidna?”. Knuckles’s face burnt red and he quickly focused on something— anything else. This got a louder laugh from his king. “How cute. Maybe you should get me off this time.” The bound echidna knew damn well he could NOT fit that into his mouth, it was 8 inches at least. He shuddered just thinking of it choking him… though this thought seemed to excite EXE. 

He gathered the leash and pushed Knuckles’s head forward, and pushed the thin tip in, allowing him to lick it and get used to it. A soft huff left his mouth at the feeling of his warm and wet tongue against his member. “Mmf~” he huffed. He tangled his fingers in his quills and pressed his head down gently. The king’s cock was now halfway in, he could feel his captive’s frantic nose-panting against him and smirked. With a smirk, he commanded “Come on, give me a show. Pleasure your king.” and Knuckles knew he had to obey. He reluctantly rolled his tongue, he couldn’t do much with his mouth due to the metal ring but did the most with his tongue. EXE huffed, reaching up and absentmindedly fiddling with one of his nipples. “My my, for a straight man you sure can work your mouth.” He commented, pushing his head down ¾ of the way. His cheeks puffed slightly, the tip was beginning to enter the back of his mouth and he had to breathe through his nose. He could taste his precum on his tongue and feel it dripping. The noise he was able to keep down, but the drool spilled out of his mouth and dripped onto his broad chest. Feeling in his arms was fading, the rope felt like it was digging into his very flesh. “Hnnghk—“ he coughed when the tip hit the back of his neck. Every pulse, every throb, every stutter of his cock he could feel in and against his mouth. “Mmghn… ghhk…” EXE smirked, and finally pushed his head down fully, his nose squashed against the base of his stomach and buried in the pubic fur, and his mouth stretched around the base. “Hahhh… your mouth feels wonderful ~” EXE moaned, having to resist facefucking him right then and there. “Move that tongue of yours… put on a little show for me.” Knuckles wanted to sink his teeth into his cock and shred it, but the metal ring kept his mouth wide open. And, the threat of the metal around his neck searing him loomed over like a cloud… so, he began to roll his tongue against the base, tracing the veins and muscles, swirling around the tip… Wet gags and the occasional cough along with EXE’s lewd moans filled the room. “Ohhh, fuck yesss~” His king was moaning louder and louder, he gave the leash just a bit of slack. “I’ll give you some leniency, move your head a bit~” Slowly and reluctantly, Knuckles moved his head back and forth, dragging his tongue up the length of his cock as he went up, swirling around the head, and descending back down, puffing his cheeks and humming around the base. “Fuuuuckk~” Wet, sloppy sucking sounds began to emerge, melding with the Void king’s lewd (and rather exaggerated) vocalizations perfectly. Surprisingly, Knuckles was forming a good rhythm with his mouth. “Hmmgh… hggk…” A hand on the back of his head pushed down, EXE beginning to speed him up. “Just like that… Pleasure your king!~” he panted, bucking his hips up into his mouth. “Mmgk! Hnngh—!!” Knuckles slightly struggled to keep up, praying he wouldn’t choke or throw up. EXE felt his balls pulsing, and pushed the echidna down onto his cock fully, shoving the full length into his mouth. With a loud moan, he erupted a hot volcano of cum into his mouth and throat. “mmMmGHK!!” Knuckles’s eyes widened as he struggled to breathe. “Swallow. Swallow it all.” And with a shudder, he did, gulping it all down. EXE smiles and pat his head. “Good boy. Now time for me to reciprocate~” He pulled his softening cock out of his mouth, watching the strings of cum drip from his mouth, tongue, and down his chin.

EXE lifted Knuckles onto the bed, and warped his bindings, thank God— from the reverse prayer and frogtie to a tight spread-eagle. It felt minimally better, at least his arms weren’t forced into an unnatural position anymore. The ring gag came off too, allowing him to relax his jaw. “L-let… Me… Go…” he panted, a flicker of resistance still burning in him. Once again, this didn’t get his king to consider letting him go. He took the chain of his leash in hand, and in a flash of red light, it was fused to the bedframe. “There, now… let’s get you all fitted.” 

Out of thin air, he summoned the same 2 clamps, these were attached with a chain and had 2 love eggs clipped and dangling from them. EXE pressed Knuckles down and clipped the first one onto his right nipple, making him hiss through his teeth in pain. With a smirk, he adjusted and turned the small knob until the clamp was squeezing down tight on the poor nub. “Hnngh—“ the bound echidna huffed. The pangs of pain on a very sensitive area of his mixed with the jolts of undeniable pleasure beginning to creep into his loins. The next one was clipped on, and was tightened equally cruelly. “G-get these off!” “No can do, my little warrior. You’re a bit too coarse for my tastes… you just need to relax~” A small pink bottle suddenly formed itself into EXE’s hand, it had a heart-shaped top and was labeled in fancy writing— ‘Asmodeous’s Ambrosia’. An aphrodisiac.

Knuckles was not as stupid as he let on- he had a very good idea of what aphrodisiacs were and what they were for. He had used them himself, though the ones he was used to were to increase his stamina and dominant energy with Rouge. This clearly wasn’t meant for dominance, and EXE knew that. “Don’t y-you dare…” He tried to demand, though his voice wavered. “Make this easy… open wide and let me pour this in.” As expected, Knuckles clamped his mouth shut and turned away, like a disobedient child refusing their vegetables. EXE tutted, and suddenly grabbed and pinched Knuckles’s nose, uncapping the bottle and holding it close. “Open.” This wasn’t going to get him anywhere— so, he just barely parted his lips. EXE stuck the tip of the bottle between them, pouring at least ⅔ of it in. It had a sickeningly sweet medicinal taste, like cherry syrup. And, of course, he swallowed. “Good boy.” EXE pat his head. “It should kick in around 10 or 15 minutes. It’ll make you feel like your brain is melting, and make you be the stupid himbo manwhore you were always meant to be. Enjoy your last few minutes of agency~” he teased.

“And of course—“ A ball was suddenly wedged behind Knuckles’s teeth, forcing his mouth open and clicking behind his head. “Mmgh!!” He half growled, half whined. EXE booped his nose playfully, “Sorry Knuxy. I can’t let you try and bite me~,”. He ran a finger over his tender nipples, and palmed at his chest. “Mmm…” A soft click of a button sounded, and the love eggs attached to the clamps began to vibrate. “Hmmng…” The vibrations sent slivers of pleasure down his spine, forcing some utterly adorable muffled moans out of him. As he watched, EXE worked both of his hands, one reaching in between his spread legs, another gently wrapping around the chain connecting the clamps— and yanking, hard. A loud yell of pain/moan of pleasure escaped the ballgag, and his back arched up. Just for kicks, EXE released the chain and gave his left pec a loud, wet SLAP, watching it recoil slightly. “MmMMMgh!!” A protesting whine hit his ears, he only smiled. “Sorry Knuxy, I need to warm you up.” His hand began to rub deliberately against his slit. “Really warm you up…” He repositioned himself so he was sat between his thick legs, absentmindedly groping his firm thigh. The hand returned back between his legs, pressing and rubbing against the slit. “Mmff..!!” Knuckles tried to protest. “Ghht hnnf!!” He growled… though the moans began to increase in volume. EXE pressed more firmly.

What he didn’t expect to feel was a tight, wet hole. “Oh?” He questioned, leaning down. Knuckles felt a panic spike in his chest. 

One hand went and directly held his slit open, revealing something that looked like a gift from God Himself— Knuckles’s pussy. His clit-dick was practically throbbing with forced pleasure. “What’s this?” Knuckles was utterly mortified, while EXE felt his arousal mount to unimaginable degrees. 

His head lowered, and he rolled his long, inky black tongue out, dragging it sensually up his captive’s inner labia. “MmmMMph~!” Knuckles let out a sound that was a mix between a cry and a moan. The taste of his juices were addictive and EXE wanted more. “Sounds like that aphrodisiac’s kicking in a bit early~!” He commented, slightly muffled. It was clear EXE had practiced, he was as good with his mouth as Knuckles was. He curled his top lip, keeping his sharp teeth away from his lovely and thick butter bean. He sandwiched it between his lip and his tongue, rolling and rubbing, even giving it a gentle squeeze from time to time. This sent genuine waves of pleasure up the echidna’s spine, the aphrodisiac clouding his better judgment and the vibrating nipple clamps only making him even more sensitive.. He had to hold himself back from rolling his hips up to meet the evil hedgehog’s mouth. Kissing a hot trail down his plump lips, EXE swirled his tongue around his leaking opening, teasing him with the tip. The flame of anger and defiance had died out in the warrior’s chest, now replaced by a mindless, pleasurable buzz of horny obedience. His red quills contrasted beautifully with the black comforter, and the golden chains binding him were lovely accents. The ballgag even matched the color of his quills. He felt his brain nearly shut off as EXE pushed his tongue into his opening, greedily sucking his juices which practically gushed out of him due to his skyrocketing horniness. His hands pressed against his inner thighs, massaging the areas with his thumb. When he had gotten his fill of his juices, EXE moved back up to his clitdick, using this as an excuse to bury his snout in Knuckles’s pubic fur, inhaling deeply. This time, he not only wrapped his lips around his dick but his tongue too, rhythmically sucking and stroking the gorgeous and perfect love button. It was a miracle Knuckles hadn’t passed out, this move got a genuine scream of pleasure out of him and his back arched up once more. Just to get him loud, EXE yanked on the chain connecting his nipple clamps once more, forcing another yell out of his gagged mouth. His senses tingled— Knuckles was getting close to cumming his brains (or what was left of them) out. As much as he wanted to suck him dry, he wanted this to last— so, right when Knuckles could feel himself about to tip, right when he could feel the coil in his stomach springing— 

EXE pulled back, uncurling his tongue and sitting back up. Knuckles whined loudly, his hips arching up. “Mmph! Lhht mm chhm!” He begged, looking at his king with pleading eyes. EXE smiled sweetly, stroking his cheek tenderly. His patched up glove was eerily cool, contrasting to the warmth that Knuckles was radiating. He cooed, “N’aww, I know you wanna cum, but we need to save that until the end!”. His hand trailed back along his inner thigh, rubbing soothingly and waiting for him to calm back down, which he did, his breathing steadying and returning to normal. “Good boy. That’s my good boy.” Knuckles felt a slight tug in his chest when he said that. He… he was a good boy. A very good boy. EXE looked down at him, and felt he needed even more enhancements. He forged and formed 2 things— a small, golden ring, and another bottle, this one was small and blue and had a diamond shaped top. This one was labeled ‘Succubi Sensitizer’. First, he pushed the hood of Knux’s clitdick back, exposing it in all of its glory, adoring the slight shudder he got in response. He slipped the ring over it, and it ever so gently shrunk at the base by a millimeter, holding it fast. It didn’t hurt at all, instead, it was extremely pleasurable. EXE traced a gloved finger over the engorged nub, throbbing with absolute need. “Now to get this lovely stuff rubbed in…” He drizzled a generous amount over his vulva and especially on his dick. 

For a scant moment, he just watched, watched the substance drip and drool down his labia, watching it enhance and rejuvenate the skin, watching it mix with his gushing juices…

 he couldn’t wait to shove his fat cock into his cunt and breed him.

Pressing a thumb against his labia, he massaged the sensitivity increaser in, rubbing his fingertips over the skin and flesh and paying special attention to his lovely dick. While doing this, he decided to give him a little relief and slipped a slick finger into his vagina directly, the sensitizer working at his inner vaginal walls as well. The action wasn’t forceful, he allowed the finger to glide in smoothly. He pulled it out teasingly, getting a whine, circling around the rim of his entrance. His other hand came into play, also tracing a lazy circle around his poor neglected dick. At this point, Knuckles’s brain was fully clouded, thoughts of being an obedient, horny, dumb himbo slave for the corrupt Void king dominating all of his processes and all original thoughts of resisting, fighting, thoughts of being the guardian of the Master Emerald had vanished. The weight of the collar on his neck and the feeling of his body pressed flush to the comforter as his King touched him had driven the point home— he was EXE’s slave. While softly rubbing his dick between 2 fingertips, EXE pressed the other finger back in. An even stronger wave of pleasure wracked the echidna’s body, his tail shuddered. The sensitivity agent had heightened the sensitivity of his inner walls even further. The Sonic impostor swirled the finger around, collecting the gushing liquid on the digit. “Mmph~!! Mmgh hnngh~!!” He cried out. Just then, a second finger entered, pressing into his tight cunt. “MmMMMph!!” His teeth sunk into the gag, the stretch felt amazing. EXE chose to remain silent as he just watched. He began to make a scissoring motion with his fingers, and Knuckles nearly passed out… again. Working like a master, he smirked and pressed 2 fingers right against that little spongey spot. “MMPH!!” “Ohh, you like that?” He asked, pressing onto it again and again like he was rapidly ringing a doorbell. This action sent uncontrollable waves of pleasure over the echidna, wracking his muscular body, he shook so violently that the chains groaned scantly. Knuckles could feel his blood rushing in his ears, his eyes rotated upwards as the arousal consumed him, consumed his very being. With desperation, he clenched down around his king’s fingers— wanting more— needing more. His entire world had shrunk down to the molten hot center between his legs. Drool streamed from his gagged mouth, staining the plush comforter beneath him. A thin sheen of sweat coated his body, accentuating each strained muscle. As EXE rubbed his dick, he could once again sense his slave coming close. He decided to let him go, just for a little longer, just to let him feel hopeful— then pulled away, pushing him closer but not letting him tip. This prompted a whine, Knuckles tugged on his restraints and looked to his king with pleading eyes. The ache between his legs throbbed like a bass drum, he needed to cum, he needed to cum, he needed to c—

EXE held his face gently, returning his gaze. “You look adorable like this. Behave.” “Mmph…” The king’s cock had begun to climb back to life, peeking back out from the slit. Once again, he multitasked, stroking himself idly while slipping the ring from his slave’s dick. He whined slightly from the removal, but if anything he was slightly grateful, the overstimulation was chipping away at his sanity. EXE slathered Knuckles’s juices onto his member, giggling as he saw him staring again. “You fantasizing about this bad boy plunging down your throat again? Naughty, naughty.” Just then, he produced a strip of black cloth. “This’ll keep you focused…” It wrapped itself around Knuckles’s eyes, blinding him. Once again, he whined. “Mmhn…” EXE pat his head gently. “Awe, don’t worry, it’ll just make you more sensitive. He went back to idly stroking his shit. The thumb swiped over his tip, precum beginning to leak out the small opening. “You look adorable like this.” When his cock stood at full attention, he repositioned himself so he was kneeling upright between Knuckles’s legs, his thick member aligned perfectly. 

With a thrust of his hips, he pressed in, sinking himself into the other male’s wet, tight heat. He didn’t even try to hold back a moan, his hands grasping onto his hips for leverage. 

“Fuck… you’re so tight and wet…” he moaned, reaching up and giving the chain of his nipple clamps a little yank, getting an adorable little yelp-moan in response. Knuckles was in absolute heaven, his master’s big fat cock was stretching him out and pressing against all of his pleasure points. He had acclimated to the nipple clamps by now, but their incessant vibrating was just another thing overstimulating him, forcing as much pleasure onto him as possible. EXE just held there, the 2 males’ pelvises static against each other. He regained his composure, and slowly began to slide himself in and out of his cunt, feeling the stretch and resistance made it feel like his dick was supported from all sides. Thumbs dug into his hips, holding him down against the base. He couldn’t help himself, he practically threw himself down against his torso while his thrusts slowly picked up speed. Teeth sunk into Knuckles’s shoulders, breaking the skin and drawing blood. “MmMMMph!!” He cried with a mix of protesting, pleasure, and pain. The king felt a slight twinge of guilt, so he kissed over the bite tenderly, stilling his hips for a brief moment. Opting for licking and light biting instead, he peppered his neck and collarbones with his ministrations, especially around the area the metal collar was fastened. “So cute…” He propped himself up by his hands, hovering over the gagged and blinded echidna and thrusting down into him. His deep indigo quills flowed down over his shoulders as wet and lewd slapping sounds filled the room. Knuckles was a loud, moaning mess, his brain clearly mulched. Through deep pants, EXE half-asked “Can’t think anymore? Too stretched to form a thought of your own?” His hips slammed down particularly hard, getting a slight shout out of him. “Good. Pets don’t need to think about anything other than serving their masters.” His eyes traveled down to the spot just below Knux’s bellybutton, watching a small, slight bump form against the toned surface. “Can you feel me?” His thrusts began to speed up, his hands gripping his hips like a vice. “Can you feel me stretching you from the inside out?” His cock pressed perfectly against his g-spot, rubbing it over and over and over and over again. He had leaked so much a small puddle was forming below his pelvis. Just then, he felt something practically spear against him— EXE had hit his cervix. A muffled shout left his gagged mouth— it hurt— but his master only continued. He gripped his hips so tightly his gloves tore a bit and his claws pierced the skin, leaving deep, bloody scratches. Poor Knuckles was being bombarded with the pleasure of being stretched with the pain of having his cervix hit and his hips scratched open. EXE continued jackhammering, his hips slamming down hard into him and brutalizing his cervix, hitting hard against it and demanding entry. He yanked his nipple clamp chain yet again, and suddenly removed his gag. “Beg. Beg for me to let you cum right now.” He demanded harshly with a hint of desperation. Knuckles responded, through moans, “H-hahh— Please, my king, please let me cum—“ “Louder.” A harsh yank on the chain forced another whine out of him. “Please, PLEASE let me cum, my king! Please, I beg of you! PLEASE!!” He mewled, utterly pathetic. 

And to reward him, EXE sped up his thrusts, hitting everywhere in him perfectly, his claws sinking into his hips. “Cum. Cum now.” He demanded. 

The world seemed to stop spinning on its axis. 

Then it stuttered. 

Knuckles’s back arched and a loud yell of pleasure left his mouth as he came harder than he had ever came in his life, his legs trembling as he came in 3 hard spurts. And EXE kept thrusting through it all, growling and panting, chasing his own orgasm as well. With a loud, primal groan, he came too, the hot cum rushing into Knuckles’s uterus and filling it, creating a small, rounded bulge on his lower stomach. Their orgasms both lasted 30 seconds, before they came back down from their high.

EXE just stayed there, buried to the hilt in his captive, wanting to stay like this— keeping him plugged like a cork, full of his cum. But, he had to move eventually. With a wet pop, he pulled out, watching with pride as his hot, thick cum leaked out of the echidna’s twitching cunt. He undid the blindfold, gazing lovingly into the other male’s eyes. The restraints came off next, they were unneeded since the collar was magically fused to the bedframe. Knuckles rubbed his wrists, still panting and the aphrodisiac still coursing through his system. EXE removed the nipple clamps, rubbing some massage & restoration oil on his tender nipples. Next, were the deep scars on his hips and the bite mark on his neck. …He decided to just bandage the hip scars, he hoped they formed scars so Knuckles knew who he belonged to. “You did so good.” EXE praised sweetly, patting his head. Knuckles could only muster a “th-thank you.”. The cover lifted, and EXE pulled Knuckles under with him. He disabled the lamp, plunging the room into darkness. 

“Goodnight, my little toy.”

“Goodnight, my king.”

And, Knuckles soon fell asleep.

Chapter Text

When he awakened, the first thing greeting Knuckles was a pain in 2 areas– a sharp, shooting pain in his hips, like something had scratched them hard. He slid a hand down to feel the damage and touched the cloth bandages. The second pain was deep in his stomach like someone had reached up and used his gut like a punching bag, it spread from the bottom of his stomach to his crotch area. “Hngh…” he groaned. His arms and legs felt like he had been stretched on a rack, and his jaw was sore and aching as if he had tried to eat a jawbreaker. He had little to no memory of the night before– figures, EXE must’ve messed with his memory and made him forget what happened… but the bite mark on his shoulder already gave some unpleasant hints he’d rather not think too deeply about. He opened his eyes and sat up the best he could, noticing where he was. The bloody crimson light of the Void sun shone through the ornate window, casting a red glow over the royal bedroom. What… what did happen? With a heave, he swung his legs, which were slightly shaking, over the side of the bed, only to feel a tug on his neck pulling him back- the collar was still there, and it was magically fused to the bedpost. The echidna huffed at that, reaching over and attempting to jostle it– only to feel a harsh zap to his hand. “Ow!” His hand pulled back quickly, nevermind. The door swung open, and the man himself walked in. 

“Oh, good morning, Knuxy~!” EXE said in that stupid smug voice. “How was your sleep?” He sauntered up to him, patting his head. Knuckles groaned and leaned his head to the side, avoiding his touch with disgust. “Get… off of me…” he tried to snap. “Oh, still so resistant. When will you ever learn?~” The leash un-fused itself and traveled to EXE’s hand, and he gave it a tug. “Come along, Knuxy. We have a long day ahead of us~” Reluctantly, Knuckles followed, glad that he wasn’t forced into an uncomfortable bondage position and was given the gracious privilege of being allowed to walk like a normal person. “What did you do to me last night?” He demanded. “I know you did something and made me forget it.” EXE just smirked, continuing to tug him along, once again letting the question hang. “I think you deserve a show around the palace. After all, you will be staying here for the rest of your life~”

With a sickeningly sweet giggle, EXE lead Knuckles out of the door, and down the hallway. There were various ornately-decorated doors on either side of the hallway. 

The first door was opened, a deep gray door with carvings of bones on it. Inside, there was something that looked like a black leather examination table, with buckles on the armrests and legrests. To the side of it, there was a whip, paddle, chain leash, and ring gag hung up on hooks. The sight of studs on the paddle made Knuckles feel a definite flicker of anxiety. Just then, he swore he could see a closet. Just to make things even more uncomfortable, there was a stereotypical black ‘sexy nurse’ outfit hung up in it. He wondered if EXE wore it when torturing his… no NO no get that image out. It was clear—this was a room for spanking. EXE shut the door and led him to the next room; this one had a tall, thin door that was colored white. 

Like it sensed EXE’s presence, the door swung open. It was red and black themed and much more sadistic-looking, it had an actual medieval stretching rack in the center with 3 suspended and empty bird-like wire cages. A strong stench of iron hit Knuckles’s nose.  All 3 of the cages had 2 pairs of black shackles, waiting for their next unfortunate victim. And of course, the rack had a whip hooked up next to it. Only this whip was spiked. Not studded, spiked. With metal spikes, it looked like it could strip skin. The walls were painted a deep maroon, and the same red torches from the throne room were mounted on either side of the rack. It seemed like spikes and sadism were the main thing in this room. And… did he just spot a framed painting of a bound and gagged Shadow getting whipped–?!

Time was money, and the door was closed before he could look closer. Knuckles was tugged along to the third room, a round-top blue door with a gold handle. This room was (comparatively) tamer, a breath of fresh air. A dark blue Saint Andrew’s Cross was in the corner with several golden buckles along its beams for restraint attachment. It had a circular rug below it that had a golden ring and a blue electric pattern. There were several hooks on the ceiling with cerulean cuffs dangling from them. On the left of the Saint Andrew’s Cross, there was a shelf with a great number of ‘toys’ organized neatly, with them all in perfect color coordination with the room. Thankfully, no spikes or studs were found on them. The room was illuminated with blue lanterns that hung from the ceiling, casting an almost mystical light. The theme of this room seemed more ‘sexy-torture’ than, well… actual sadistic gorey edgy torture. Just when Knuckles swore he could see another painting, this time of Sonic, EXE closed the door again. 

“Wait, what was that painting?” He demanded, digging into his heels. EXE turned around, raising an eyebrow. “What painting?” He asked innocently. “I saw a painting in there, and in the second one too.” Knuckles reached for the handle, about to turn it, though it didn’t budge. Just then, he saw red light swirling around his hands. “Silly Knuckles…” EXE cooed, walking calmly over to him and patting his head. “Silly, dumb dumb little Knuckles.” The light fitted itself to Knuckles’s hands in a swirling display, and faded away to reveal thick, shiny latex mitts– rendering his hands, and even his spikes into adorably useless nubs.  “You think these are gonna stop me?” Knuckles grabbed the doorknob with his mitts, turning as hard as he could. EXE just watched, his arms folded across his chest. It was a cute sight– like a puppy pawing at the door, wanting its owner’s attention. Tutting, he patted Knuckles’s head again, stroking his quills. “You’ll never learn, will you?” Sighing, he waved his hand, and a patch of black leather approached Knuckles. It bound both of his arms behind his back, reinforced by several buckles that clicked themselves down to the last hole of their belts. It formed an armbinder, keeping his (nub) hands where EXE could manage them. Knuckles couldn’t tell if this was worse or as bad as the reverse-prayer, his arms ached awfully. The straps bit into his powerful muscles, making him actually sink to his knees, hissing through his teeth. “You asshole! Did you seriously need tooOOMMPH!!” A spherical, dense ball forced itself into his mouth, wedging his muzzle open, and with it two straps emerged and connected themselves behind his head, effectively shutting the echidna up. “Yhh hhssle!!” He yelled into the gag. The rubber ball invaded his mouth, no matter how deep he sunk his fangs into it, it didn’t budge. EXE sighed, pushing Knuckles down onto his knees, delicately putting the tip of his shoe on his forehead and tipping his head up to look at him. “You really are a stubborn one.” The armbinder kept Knuckles’s arms in an unnatural and rigid position, sending shoots of white hot pain against the flesh. “Perhaps you need a reminder of who owns you.”

EXE fiddled with the chain in his hand, considering if he should burn or choke him again… no, he’d save that for later. Instead, he gave his same old chuckle. “In this castle? I control everything. Windows are blocked from letting sunlight in at my call. With my command, the bricks could melt into magma or freeze eternally. Lanterns and all light sources could illuminate so powerfully they will blind or cascade the halls into eternal darkness.” With a harsh tug, Knuckles was sent falling onto his chest. “Fghh–!” Pressing in his knees, he was about to rise but a shoe dug into the back of his head, keeping his head down against the rough ground. “The doors will respond to my commands only. Everything in this castle, every little molecule– belongs to me.” The king dug his heel into the back of his head harshly, getting a groan of pain. “And that includes you, Knuckles.” He lifted his foot up, allowing Knuckles to almost worm away, before stepping on the top of his back that the armbinder exposed, getting an even louder groan of pain. “STHHP!” Keeping the foot wedged into his back, EXE gripped one of Knuckles’s dreads and yanked his head back. “I own you, Knuckles,” he growled into his ear. “Must I remind you every time you try to regain agency? I own you. I could stop oxygen from going into your lungs without a second thought.” The heel dug in even harsher as Knuckles could feel himself losing feeling in his arms again. His heart was hammering out of his chest, he was… terrified. “You think you stand a chance against me? Me ?” EXE yanked the dread back so hard Knuckles feared his neck being snapped. He leaned down to his ear, and whispered– “If you’re so insistent on being an insolent little brat, I will not be afraid to take you apart, fiber by fiber.” It didn’t stop there, he kept going. “Every cell belongs to me. It always has and it always will.” A sharp claw trailed along his neck, just beneath the collar. “I will intimately know every piece of you.” His voice sounded almost demonic. “I will take you apart. ” The panicked heartbeat of his slave only fueled him. “I will study, twist, violate, and devour every fiber of your being.” For a scant minute, he just stayed like that, keeping Knuckles pinned under him with the threat of opening his neck lingering in the air. “So. Will you behave?” He gave the smallest of nods. “Good!” EXE’s voice returned to normal.

He got up, and pulled Knuckles to his feet. The imprint of the heel on his back almost took his mind away from the pain in his arms. “Let’s get on with this, then. Now that you know your place.” EXE continued walking along the hallway, showing Knuckles rooms that only got increasingly uncomfortable to look at and just ever so scantly thrilling him. 

——————

“I think you get the idea. Keep that tough guy facade up, and you’ll be seeing the inside of any of these fun rooms.” EXE said, at the end of the hallway now. “Oh, right!” He snapped his fingers, and the ball-gag in Knuckles’s mouth disappeared. He felt grateful to have feeling in his mouth again. “Any questions?” the king asked. Knuckles took a deep breath, before answering– “What… what were those paintings in the second and third rooms?” he asked, keeping himself from sounding too demanding. 

“Ah, I guess I should show you those myself. However, let’s get you into something more, fitting… hm?” EXE’s idea of ‘fitting’ was definitely not in line with one’s traditional vision of ‘fitting’, but normalcy is a mere word in the eyes of the Void King. With a swirl of leather and buckles, Knuckles’s armbinder was instead reformed into a constricting bitchsuit. His arms and legs were both bent fully, wrapped with shiny black leather and reinforced with the same leather straps from before, their buckles glinting in the light. The mittens rendering his hands useless remained, though they were connected to another gift from the ever-so-gracious king– a posture collar. It kept Knuckles’s neck utterly rigid, allowing meager inches of movement or turning of his head. To sink in the humiliation, there was a golden tag on it: “Property Of The Void King”. As for his legs, they too were bent double, reinforced by the same shiny leather and biting straps. His heels were squashed uncomfortably into his firm glutes, all of his muscles strained. “Whh–what the hell?!” Nope, screw talking nicely. “Why THIS?!” EXE sighed, and formed a new obstructor to the echidna’s speech– a black muzzle that pressed over his own, only allowing his nose to be free. “MMphh…” he groaned in annoyance. Why oh why must he voice his discomfort… The bitchsuit kept him crawling on his elbows and knees, thankfully with padding to protect the joints from the floor. Without really thinking, EXE reached a hand down and gave Knuckles’s ass a hard, loud smack. “MMPH!!” “Sorry, couldn’t resist.” he chuckled. “Now let’s get you to those rooms you want so desperately to see.” EXE made a U-turn, and gave the leash a much gentler tug, wordlessly telling him to follow. 

It was easier to crawl on his knees, but crawling on his elbows proved difficult. And the posture collar disallowed him to look down, so it was a very awkward sight. “Mmpft…” he groaned, managing to just slightly get the hang of it… when he slipped and fell onto his belly. EXE laughed at the sight, stopping to pet his head. “You’re so clumsy. And you’re the guardian of the Master Emerald?” He absentmindedly squeezed his right pec. Knuckles growled and managed to upright himself, continuing to crawl along. After many slips, humiliating comments, and unwanted gropings, they made it to the door of the second room. It swung open for EXE, who strode in with Knuckles in tow. The red glow of the torches reflected off of the harsh buckles keeping him docile. Knuckles then saw it perfectly— the painting of Shadow.

The Ultimate Lifeform was bound face down onto the rack, his limbs stretched to an already painful extent, the gleaming shackles digging into his wrists and ankles. His hands were clenched, as if he was futilely trying to summon his abilities. His face was contorted in restrained agony, tears pricked the corners of his eyes, and a ball gag was locked into his mouth, the same one that Knuckles had the unpleasant honor of wearing moments before. His back was utterly littered with angry red marks, some crying tears of blood and some even scantly showing the raw layers of skin beneath his dark fur. The same spiked whip was mid-strike, ready to deliver its next blow to the black and red hedgehog. The painting captured every detail perfectly, Knuckles could almost hear his muffled yells of suffering.

“Shadow’s fine.” It was like EXE could read his mind. “I don’t know where he is, and I know he’d be much more of a pain in the ass than you are.” “Mghh…” Knuckles groaned in response. EXE patted his head, then tugged the leash. “Alright, now onto the next room you so desperately wanted to see.” Knuckles followed after him, starting to somewhat acclimate to the bitchsuit. He crawled in his tow, and they made it to the next room. Knuckles was right, this room was, at least comparatively, tamer than the others. Despite the posture collar, he managed to look up at the painting.

Sonic was bound onto a sybian, his arms trapped behind his back with a strict armbinder. The straps dug into his blue fur, restricting any movement and keeping his pelvis immobile. A blindfold obscured his sight and a ring gag wedged his mouth open, strings of drool falling onto his chest and puffs of air surrounding his gaped maw. Glistening tears ran down the sides of his muzzle, catching light. The sybian was at full power, overstimulating the poor hedgehog. Wet, glistening trails of leakage slid down the side of the sybian, forming puddles around his knees. Knuckles felt a slight pulsing feeling in his loins, and quickly tried to ignore it. But he couldn’t, the sight of his usually confident friend bound and having orgasms forced out of him… it did things to him. For the record, he’s still straight as a board. Don’t get any ideas!

“Alright, that’s enough of that.” With a wave of his hand, the pair was back in EXE’s bedroom. “Let’s get you out of that.” The bitchsuit, gag, mittens, and posture collar all literally fell away into the ground, swirling in the dark floor, leaving only the metal collar behind. Finally, he stood up, rubbing his sore jaw and stretching his strained arms and legs.

Knuckles was at the end of his rope. “No more lies,” he demanded. EXE’s mouth turned up into an amused smile, though he would be a liar if he said this display didn’t titillate him, just a bit. “Tell me. What did you do to me last night?” Well, he couldn’t hold it over his head forever. “Well, words can be interpreted in any way.” EXE had to pull some stupid magic BS once again, and materialized a holographic floating circle- a mirror into the memory. “Let’s have a look-see.”

Knuckles was met with a horrifying image of himself. He was bound onto his captor’s- his rapist’s bed, blindfolded and gagged. EXE was torturing him, pleasuring him in a disgusting way. His face was buried between his thick legs, eating him out and greedily sucking him dry. The vision made his stomach drop to his feet. He was the Guardian of the Master Emerald… and this … was what had become of him? He looked to his shoulder, the bite mark embedded in the muscle was like a brand from red hot metal. EXE was right. He wasn’t a warrior, not anymore. The deep scars in his hips proved that even further. 

Panicked, Knuckles began to think- he imagined himself sleeping in his bed. This was all just a bad dream, right? He would wake up back in his bed, with Sonic and his friends, and this would all just be an awful nightmare. Blood rushed in his ears and his throat dried up. This was no nightmare and he was wide awake. Rouge… she was going to hate him. Everyone was. He let them all down, he was supposed to be their rock and protect them… and he let himself get raped. He wasn’t worthy to guard the Master Emerald. He wasn’t even worthy to step foot on Angel Island. The dream display continued, and Knuckles was unable to look away. It was like watching the Death Egg implode, you couldn’t look away. 

EXE smirked as he watched Knuckles fall apart from the inside. The echidna’s legs gave out, and he sank to his knees, clutching his head in his hands. His back shook with terror and tears began to prick the corners of his eyes. His vision disfigured and blurred, he was faintly surprised EXE didn’t give him a hallucination of anything. This is what happened… Knuckles dug his hands into his dreads, his claws nearly digging into his scalp. The pounding of his heart rang loud like a powerful bass drum. His stomach clenched violently, he almost threw up. Almost. The vision kept on playing. 

He then heard it .

• “Beg. Beg for me to let you cum right now.”

• “H-hahh— Please, my king, please let me cum–”

• “Louder.”

• “Please, PLEASE let me cum, my king! Please, I beg of you! PLEASE!!”

His own voice begging for that… thing to let him cum. He barely recognized himself anymore.

With trembling panic and anguish, Knuckles looked up at EXE, his muzzle glistening with tears and cold sweat. “Wh… what did… you… d-do to me…?” EXE smirked. “What you’ve always wanted. You were begging so sweetly!” EXE began to walk around him. “Don’t act all prudish now. I can tell when you want something. When you need it.” He set a hand onto the bite mark embedded in his shoulder, sending sparks of pain down his spine. “And what you needed was for me to claim you, cum inside of you and make you my bitch.” EXE’s voice sounded different. It sounded warm . Like he was comforting a crying child. “N’aww, why the frown?” Knuckles felt a deep sense of dread, and something else. Something hot and fiery.

This thing violated him, broke him down into nothing. He sank him down and cut him to the quick.

It was only fair Knuckles returned the favor.

Bracing himself against the floor, Knuckles eyed EXE like a hawk. This had to be timed perfectly. This bastard had ruined him from the inside out, so he might as well ruin him from the outside in. When the king was distracted, still gloating about his ‘victory’, Knuckles charged forward like a trackstar. He would have made some sort of victory yell or grunt, but this… thing didn’t even deserve that. 

His left arm pulled back like a slingshot, then with the force of a thousand Death Eggs, his fist collided with the side of the bastard’s muzzle, hitting as hard as a bowling ball. 

It all happened so fast yet so slow. 

EXE didn’t even have time to react, his red pupils shrinking to pinpricks. His mouth squished into an almost comical pucker, inky black spittle and even a single yellow tooth spraying out. He was literally lifted off of his feet, and slammed back into the wall, leaving a halo of cracks against the ebony. Internally, he wouldn’t have been surprised if the warrior had punched him through the wall. 

In a nanosecond, Knuckles was greeted with a transparent, glowing red shield, surrounding and protecting the king. “Really?” he scoffed. “Bring down that forcefield and face me like a real king!” he demanded, resting his hand against the forcefield. 

EXE rubbed his sore jaw, and rose to his feet. The tooth regrew instantly, and with a sickening crack his neck snapped back into position, looking right at Knuckles. Pure blackness filled his eyes, but Knuckles showed no fear.

How… how dare he? How dare this creature– this thing – 

Bones snapped and muscle pulled as the king felt his form changing. Knuckles stepped back, prepared for anything. “What are you doing now?” There was no answer. EXE fell onto all fours, his spinal discs elongating into sharp spines, the ashen gray bones stabbing through his back. The spine itself elongated, pulling the muscles and skin with it like stretchy slime. 

EXE realized he was smiling.

Gloves were shredded as the humerus began to lengthen, pulling the muscle taut. The skin split apart as the fingers and toes became even sharper, the curved claws digging into the ground. 

“k Nuc Kl e S …”

EXE’s eyes were beady little black things, and they both rolled to focus on the echidna. He stood up– his legs had stretched out too, and he was now much, much taller. Not as big as your average Death Egg but pretty damn big. His joints cracked like fireworks as he stared down at the little rebel. EXE’s mouth had changed, four black mandibles sat on either side of his mouth, lined with tiny little spikes for scraping up food. Knuckles stepped back once more, fear beginning to grip his heart.

But what he least expected was to hear… laughing.

At first, it was a small chuckle. EXE’s chest, in all its visible-rib-torn-flesh glory, shook as the laughing increased, in volume and in strength.

“Y o U f U c k eD U P , Kn uck Le S …”

He was dead meat.

Chapter Text

Knuckles’s nose scrunched as he stepped carefully through the scorched hell of his home, the noble Angel Island. After his little ‘outburst’ at EXE, he was in need of punishment. EXE couldn’t have his pet disobeying him, couldn’t he? So, EXE sent him… here. Why? No idea. The smoke singed his nose and eyes, making him rub his face with discomfort. There were no rings, no boxes of shields or invincibilities, even the Badniks were scrapped and strewn across the faded green grass. The only really recognizable remnants of previous times were the still-functioning checkpoint towers. The bridges were long since burnt, dangling from their rope suspension points, but that was no issue.

Knuckles jumped and glided to a nearby ledge, grabbing onto it and climbing up onto its high flat point to get a better view of his surroundings. He remembered this… Eggman went so hard he didn’t even care if he took out his own creations. What even did he want to bomb out Angel Island for? Those memories all seemed distant now ever since his forced submission to EXE. Surprisingly, when he rubbed his neck he realized the metal collar was gone. Thank Chaos… Knuckles was about to approach a waterfall to splash some water on his face but then stopped himself. He looked down a cliff, seeing the fish and critters being boiled alive in the lakes. Of course… the water was heated to lava-hot degrees because of the fires. His heart ached as he saw the innocent creatures squeal in pain then bubble up to the surface lifeless… He had to be cautious… one wrong move and he’d– 

“SHIT–!!” Oops! Knuckles’s foot lost its holding on a rock he didn’t know was loose, sending him tumbling down, down, down– slamming hard against the jagged rocks as he descended. He couldn’t grab onto them in time, he couldn’t–

SPLAT! A rough, sharp, and fatally thin rock formation pierced Knuckles’s head through his left eye, the bloodied tip peeping out through the back of his head. The echidna’s body twitched weakly, his trembling hand reaching to push against the rock weakly. Death was not immediate- his body gave the occasional twitch like it was being shocked with electrical currents. His thoughts were both scrambling with fear, but dull and fuzzy. He sank lower and lower, his non-impaled eye being able to see the blood pooling below him. He wanted to panic, he wanted to scream and flail and beg for help and struggle, but he wasn’t really able to do much. And it didn’t hurt… that bad? The brain had no pain receptors so that was a huge plus. And his eye? It just felt like he had a really big eyelash in it. Okay, not the best comparison but you get the general idea. Eventually, his heart gave out, and his body slumped weakly.

-1 K.T.E.

Knuckles stood up at the checkpoint, dazed. He had just had his brain speared by a rock and the memory was still fresh in his head. He had very much died. How did he…?

Lives. Of course.

He rubbed his head, looking around. Why did EXE send him here? What did he want him to do here in the burning hell of his old home? There were none of his people here and no bondage gear to torture him with. Just then, a word was telepathically sent to Knuckles’s consciousness.

HIDE.

Well, that gave little room for guessing. Knuckles climbed to a (safer) high point, surveying his surroundings for any sufficient spots of seclusion. Eventually his purple eyes settled onto a normal-looking hole next to a tree a few meters away westward. He propelled himself off of the high point and glided through the smoky air, dropping down right next to the earthen pit. 

Unfortunately, Knuckles failed to notice what was inside the hole until he had jumped in. Just then, several rusty metal spikes dug into his flesh. “AGHHH, FUCK!!” He began to flail and panic, his hands grappling at the sides of the wall and trying desperately to pull himself up. But sadly, all that succeeded in was driving the spikes deeper and deeper into his muscles. His heart was beating in his ears and throat as he abandoned all rational thought, only needing one thing- to get the hell out of here. The spikes slowly extended, penetrating the muscle and organs. The echidna’s vision was blurry and unfocused as he struggled like a trapped rat. The pain was excruciating, his voice gave out as he screamed himself hoarse. Sweat dripped from every pore, sending stings of pain into his wounds. Eventually, the spikes had extended so much that his sculptural body was immobilized, like a perfect statue of hell. Knuckles tried to calm himself down, breathing through his nose and trying to focus his vision. He was so close, he had to escape… Unfortunately, it was all futile as a single spike from the ground shot up and impaled his heart with a single shot, gifting the echidna with death.

-̵1̷ ̵K̵.̴T̶.̸E̸.̷

Knuckles woke up again at the checkpoint. So, the pit wasn’t a good idea. EXE, that bastard… he really likes spikes, doesn’t he? That didn’t change the fact that Knuckles still needed to hide. He went back to the same high point, looking eastward this time. In his peripheral vision, he was forced to see more suffering of the animals. Some Flickes had flown into the spikes on trees and were now suffering the consequences, he could faintly hear their cries of pain as they tried desperately to escape their torture. Knuckles made a mental note to make EXE pay specifically for his torture of the animals. Eventually, he came across a small spire of what looked like scrapped Badniks. A bit on the nose and a rather obvious hiding spot, but time was ticking down slowly and he had to move. 

Knuckles jumped out and glided, stopping at a halfway point by standing against a tree to get a better look. He didn’t want a repeat of… being slowly impaled, so he had to check if there were any spikes. Thankfully, there were not. He was good to go! He was gonna hide from EXE, go back to Mobius, save Sonic and Tails, maybe confess his love to Soni- IGNORE THAT. The point is, he was gonna be alright. He jumped down from the tree, and glided to the entrance of the spire. He stepped right in… and the entrance caved right in behind him. He whipped around like a startled cat, feeling nervousness set in. “...hello?” No response was expected. Not at least from a patchy Motobug with a stick for one of its missing antennae. 

“And what are YOU doing in here?” it sneered, its voice metallic, glitchy, and incredibly peeved. An embarrassing girly scream left Knuckles’s mouth as he leapt a foot in the air. “Huh-?!” He sputtered, struggling to regain his composure. “I sAid what are you doing here.” it repeated, folding its little claws and looking up at Knuckles like a mad parent. “I’m- I’m hiding.” spilled out of his mouth, “What are you doing here?” The Motobug looked deeply insulted, clutching its claw to its ‘chest’. “We’re trying to live our lives. And you need to get out!” Some other Badniks had awoken and were now slowly approaching Knuckles, their weapons readied. “How are you even talking? The animals were freed from all of you!” A Buzz Bomber crawling on the ‘ceiling’ scoffed as if that was a known fact. “We gained sentience. The evil hedgehog gave us some bullshit ‘core’ that keeps us from croaking. Now what to do with you…” 

Suddenly, a Caterkiller slithered under Knuckles’s legs, trapping them and making him fall onto his back. “What are you–” Two Crabmeats stabbed his arms through the wrists, pinning them down to his sides. It hurt, their metal legs were rusty like the spikes. “GAH- What the hell?!” Jolts of pain shot up through his arms. Why did he feel so weak?! “We think you need some comeuppance for stomping on us.” A Beetlesaw crawled out from under a sleeping Buzzbomber, its saw letting out an ear-piercing whir. Knuckles’s struggling increased tenfold, his heart hammering in his chest. 

“What are you doing?! Let me go-” No time was wasted, and the saw went right through his right bicep, just below his shoulder. “AGHHHH, FUCK!” He screamed out in pain, blood spraying everywhere as the creature took off his arm like it was nothing. His back arched as the awful, terrible sound of the sawblade hitting his bone echoed and stabbed him through both ears, mingling with the screams of his own. The arm came off and was tossed aside. 

Knuckles dissociated throughout the other 3 limbs being sawn off. He laid idly in a pool of blood, his earlier optimism replaced with… nothing. The Badniks seemed to notice this, and got annoyed. So, they took a spear made of their own discarded parts, and stabbed it into Knuckles’s heart, ending his third life. Wow, EXE sure had a thing for stabs in the heart.

-̴͖̄̀1̸̟͕̃ ̸̫͇͈͆̓͗K̴̹̥̥̉̒̄.̴̻̟̬̈́̄T̷̹̂̽́.̶̺̈́Ē̸͚.̶̢̀̂

Another awakening at the checkpoint. Huh? He had died three times. Shouldn’t he be… actually dead?

Knuckles looked out from his perspective and saw the lives counter- glitchy. Ohh, EXE did that good old 255 lives trick. Clever. Well, back to actually finding a place to hide. 

And yet again, Knuckles failed to account for the unstable platform beneath him. He descended immediately, headed for a spike. Oh, another impalement… great. But instead, he tumbled- and fell right into the boiling lake with a smack. The reaction was immediate, blisters formed and popped on his body as the hellish water scorched him. He flailed his arms and tried to get out, tried to save himself, but nothing worked. The boiling water was everywhere, singing his weakening body. Slowly, the boiling peeled away his flesh and fur, revealing the raw muscle, nerves, fat cells, and flesh underneath. The smell of scorched blood filled the air as Knuckles’s voice gave out, his screams replaced with hoarse shouts. His body felt like it was being melted because it literally was. Finally, his heart gave out and his dead body bubbled up to the surface.

Huh? Who was Dave?

Knuckles was beginning to get the heebie jeebies. His timbers were shivered. One could even say he was quaking in his boots. Time was ticking down and he had to actually find somewhere to hide instead of fucking around and dying. He went to a high point that WASN’T unstable or spiked or full of violent sentient Badniks, and really scanned the area from all points. North, south, left, right, up down, inside out. He finally found somewhere- a thick, slightly old palmtree. A bit on the nose but very not suspicious. He glided down to it, and crouched behind it. 

Unfortunately, as he was sitting, the heebie jeebies came back again. Being here brought him back to his first encounter with EXE- and his failure to protect Tails. Knuckles held a hand to his chest, trying to steady his breathing. He let Tails get captured and frozen by EXE. He let the one person left to protect get taken away. Tails was relying on him to save him and he just… let it happen. EXE’s distant yet powerful voice rang out a few kilometers away from Knuckles’s spot. 

READY OR NOT

Okay. He was okay. He was fine! EXE was gonna skip over his hiding spot and not see him. Totally! His breathing began to pick up slowly as he felt despair sink into his mind. The memories of his deaths didn’t help either. Blood pounded in his ears as his pupils shrunk, his vision flickering. He wanted to run. He had to run. He had to get away from here now… but he felt stuck to his place, trapped. Any movement would be spotted by EXE, and he’d be back in that castle and raped again and… He was not okay. He was not fine. Oh Chaos, he was gonna die. He clutched his head in his hands, pulling his knees to his chest and trying everything to steady his breathing and not explode. The pounding heart almost broke through his ribs, he wouldn’t be shocked if EXE located him soley because of his heart. He looked at a wilted flower by him, and faintly saw what looked like… Tails.

The orange foxboy’s body was rotted, maggots feasting on his right eye and tongue. His fur was moldy and patched. Knuckles’s vision blurred, his sanity beginning to fray at the edges. The body kept fading in and out of his vision, he swore he was twitching… this was his fault. He failed to protect Tails and let him die. Just as the hallucination faded and Knuckles felt a sense of calm– a loud, manic laugh sounded behind him.

FOUND YOU.

EXE was hovering above the ground, his eyes pure black and two massive black antlers piercing his head. Knuckles tried to run, but four chains materialized from EXE’s hands, the hooks on the end digging into his body. He screamed in pain and fear, tearing the ground up as he tried to run away. The demonic beast laughed like a maniac as he dragged Knuckles away, back to the castle for another round of punishment.

Chapter Text

This was new. Knuckles wasn’t back in the dungeon he had awoken in when he had first arrived. How kind of EXE to take him to new places. Now, he was in the black and red torture room. It differed from the dungeon in quite a few ways. First, the walls were ebony concrete instead of carved brimstone bricks. It still had the same red lighting from the dungeon, so that was something to remind him of his home away from home. Next, the ground was deep maroon hardwood instead of rough stone. And finally, there was the painting of Shadow being tortured. 

Knuckles himself was bound on the stretching rack, face-down. He had to turn the other cheek every odd 3 minutes to stop his neck from cramping. At least he could moderate that cramp and retain some form of control- the rest of his body was stretched tightly, the polished black carbon-fiber steel chains digging into his wrists and ankles, and stretching his body out for display. It was humiliating and painful. At least this place wasn’t muggy and humid. It was still hot, but a dry heat. 

For backstory, he had failed to hide from EXE in time– apparently, his panic attack gave away his location. Damn his stupid heart for making him feel things and curse his stupid brain for making him see things! He wondered what EXE had in store for him. More rape and torture? Maybe he’d bring out Tails’s body for that psychological kick. Or Rouge’s! He had no idea how long he’d been stretched like this, but it must’ve been a while since his arms were going cold. Jeez, EXE had really put his arms and shoulders through the wringer. Reverse-prayer bondage, that armbinder, those hooks, and now… this. 

Finally, his ears picked up a door swinging open a few hallways down, and footsteps echoing down the dark hallways. The King makes his entrance fashionably late, of course. Knuckles just let the sound of his approaching torture and his own quiet breathing fill his ears as he mentally braced himself- not for the impending torture, but for HIS scathing smugness.

After an absurdly long walk, the Sonic wannabe’s presence was felt behind Knuckles. He stood there, not saying much- before reaching out and running a hand along the spine of his back. 

“Oh, Knuckles…” He sounded like a parent who caught their kid doing something bad. 

Knuckles didn’t even bite back, he was too tired for this shit. EXE sighed wistfully and allowed his hand to come down and give his ass a gentle squeeze. “You just had to lash out… I even gave you a second chance and you blew it.” Very on brand… Knuckles’s fur bristled with disgust as he felt EXE rub his crotch slit with his thumb while feeling up his ass. “...well, these things happen, and when they do, discipline is needed. I wouldn’t be a very good pet owner if I didn’t give you discipline.” Finally, he decided to speak up. “What, making me die painfully 4 times and giving me a hallucination of my dead friend wasn’t discipline?”, his question was both rhetorical and genuine. EXE laughed dryly while prodding at his asshole with a single finger. “No, no, heavens no. That was to give you a chance to renounce your freedom and submit to me…” A small feeling of dread began to pool in Knuckles’s stomach. If being boiled to death wasn’t punishment enough… he didn’t want to know what was.

EXE’s mouth curled into an actual smile, his hand finally leaving Knuckles’s backside alone. “Let’s start off with something… comparatively simple.” EXE walked to the side, and came back with a whip in hand. Not just any whip- the metal spiked whip. He ran a gloved finger along the braided handle as he spoke, “This does have a tendency to strip flesh… I can’t wait to hear your screams echo around these boring old halls.” EXE took a step back, gripping the whip by the handle, and let it uncurl and the tip drop to the ground. “Count them. And thank me for each one.” 

He reared back, and with a sickening crack, the whip’s spiked tip dug into Knuckles’s back, taking some bits of red fur with it. Knuckles hissed through his teeth, his fingers digging into the brick wall. The pain was immediate and agonizing, but the echidna steeled himself. “One, thank you.” “Ahem…” God fucking dammit was he really doing this? Knuckles kept his anger down and kept up the front of emotionlessness. “One, thank you… Master.” “Good.” EXE reared back once more, and nearly threw the whip forward like a Wii controller without a wrist strap. The metal spikes dug into the fresh wound, stabbing against the muscle and ripping past the fat layer. The echidna felt warm trickles of blood streak down his back, the pain felt like his back was being branded with a hot iron. “Two, thank you Master.” Knuckles kept his voice monotone. If anything, this was just like his training to be a tribe warrior years ago. Sure, this was… kinkier and not done with the purpose of making him stronger, but the comparison helped. 

He just had to show no reaction to the pain. There was another ear-splitting crack, this one was on his lower back. This one had more spike to it, tearing new holes on his back. Knuckles inhaled deeply through his nose. “Three, thank you Master.” Despite himself, Knuckles began to feel the ouchies. Believe it or not, being whipped with a metal spiked whip was not very easy to ignore. Blood was pouring down his back at a much quicker rate, dripping down the muscles and dripping onto the stone floor. EXE felt a sickening warmth growing inside of him, but he needed to wait. He’d plow him when the time was right. He gave him another blow, this one was more vertical and left a stripe over the other 3 cuts. “F-four, thank you Master.” Knuckles cursed himself for the waver in his voice as the fur on his back was stripped away with each lashing, the whip’s spikes left rather gnarly trails behind instead of simple lines. He retreated back into his head again, and thought of his friends- Sonic and Tails. He’d sworn to protect them from danger, but then this mess happened… He wouldn’t screw up next time. He’d protect them from anything and everything, even if it meant he’d have to suffer through this bastard’s torment. One more lash struck across his back, this one was diagonal. “Five, thank you Master.” EXE finally de-materialized the whip, standing close to Knuckles’s back and admiring his work of art. He ran a hand along the fresh scars and exposed tissue, making Knuckles tense up with pain. “Mmmmm…” he hummed to himself. Tentatively, he leaned in and began to drag his tongue along the lacerations, collecting the delicious red liquid on his tongue. “I can tell you aren’t very reactive to the whip,” he commented between licks, “Maybe something harsher is needed.” Great. Wonderful. Fan-fucking– okay you get the idea. “Not pain… at least not for now.” EXE gave his butt a pat. “Something more humiliating.” 

The chains clicked open, and Knuckles fell to the ground with a thump. He nearly sprung up but was quickly caught with some stupid magic rope. His arms were forced into the same reverse-prayer, and his legs were frogtied again. “All this blood and violence is getting me pent up,” EXE crooned, and pulled Knuckles so he was kneeling in front of him, face-to-face with his crotch slit, “and I have just the person to help me relieve some tension.” He ran a hand along Knuckles’s cheek as his other hand began to slowly, methodically rub his crotch slit, and in seconds his cockhead slowly peeked out between the folds. Knuckles stared up at EXE, keeping his expression steeled. The demonic hedgehog began to straight up “jork it”, and by “it”, haha, well, lets justr say, his peanits. 

“Come on now…” he encouraged, giving a press to the back of his head. Knuckles leaned forward, and began to lick the thin tip of the inky black tentacle. EXE hummed quietly with satisfaction, even closing his eyes. 

Knuckles suddenly got an idea. A stupid idea. A stupid, reckless, completely ludicrous idea. An idea that would make Pachacamac and the entire remaining Echidna population look at him with awe and disgust. 

He sank lower and lower on EXE’s cock, opening his mouth to accomodate his girth…

… then bit down. As hard as he could. His sharp teeth sank into the dark flesh, tasting the black blood. It tasted weird- coppery like your average run-of-the mill blood, but with a side of ink.

The void king’s reaction was immediate, he immediately yanked Knuckles off of him. “OH, YOU LITTLȨ̶̳̽̈-” Knuckles just stared up at him. EXE immediately struggled to regain composure, breathing heavily. “You… you really…” His right eye flickered as his bitten cock retreated back into the slit like a turtle. “Hah… you idiot.” He smiled. “You’re quite the little masochist, aren’t you?” He huffed through his nose, two maroon smoke clouds fading out. “You just love giving me more and more reason to torture you.” 

With a wave of EXE’s hand, Knuckles was now laying on a table. He was strapped down with black steel restraints. His arms were together above his head and his legs were spread out wide. EXE regained his composure fully, climbing up on the table and kneeling between his spread legs. “Now… I think you need something that’ll not only show that you’re mine, but will feel like you’re mine too.” His eyes roamed over the warrior’s helpless, powerful body. The scars under his pectorals… his defined muscles… hmmmm. Branding would be too much of a hassle. He already lashed him with the whip. What else… what else…

“I know.” In a flash of golden light, three tools appeared on the table, between Knuckles’s legs.

A golden circular barbell…

A 12g hollow needle…

And forceps.

Knuckles had to slightly crane his neck to see what EXE had conjured up. When he saw the tools, a sense of dread sank in his gut. Oh no. He knew exactly where that barbell was gonna go. And EXE knew that he knew exactly where that barbell was gonna go. His smirk stretched across his face, he was practically vibrating with sadistic glee. He lifted the piercing needle with two clawed fingers, and made sure to sterilize it, the stench of peroxide only adding to Knuckles’s dread. 

Oh Chaos. Oh Chaos. Ohchaosohchaosohchaos- okay OKAY you’re fine. You’re gonna be fine! Knuckles struggled to keep his breathing steady. EXE leaned down, spreading Knuckles’s slit open, and holding his clit-hood back. He felt his dick harden at the sight of the delicious nub, but had to wait. He held the sharp end of the needle to the side of the nub,

Knuckles drew in a breath, and held it, keeping his eyes trained on the black ceiling above him- finding a divot that reflected the red light and focusing in on it, blocking out all his other senses. He clenched his fists, steeling his expression.

EXE didn’t care how Knuckles decided to cope with the impending pain. “Let’s get this in…” And with one push, he stabbed the needle through the flesh of his clit-dick. 

The pain was immediate and intense. It was like… uh… getting his clitdick pierced. He couldn’t find a good simile at this time, cut him some slack! The white-hot agony shot through his entire body, filling every vein with lava and broken glass. “Hnghhhhh…” Knuckles hissed through his tightly clenched teeth, the steel restraints groaning in tandem. He couldn’t scream. He couldn’t give that bastard the satisfaction. “Hmmmffffuuuccckkkkk…” he strained, all his muscles tensed. His eyes were clenched tightly, a single bead of a tear threatening to fall. EXE pushed the needle out through the other end of the nub, then picked up the barbell. He secured it in with a flourish, and stepped back to admire his handiwork. The gold barbell glinted in the red light, standing out perfectly. “You know…” EXE mused, materializing an obsidian dagger in his right hand. “I’ve always wondered what Mobians looked like on the inside.” Knuckles just groaned wearily, accepting his fate.

With a simple, smooth movement, EXE plunged the knife right where Knuckles’s sternum ended, and ripped a single line all the way down to where his bladder would be. The sudden scream of pain was lovely to the Void King’s ears. He didn’t even mock or taunt him as he pulled the layers of skin, fat, and muscle apart, watching the red blood spill over his captive’s sides and pool on the table. Finally, he got to see what he wanted to see- Knuckles’s digestive organs. He ran a gloved hand over his exposed small intestine in what could be called a soothing motion. 

The echidna warrior’s vision was getting blurry, his heart thumping against his ribcage erratically like a rabid animal trying to escape containment. And yet Knuckles himself was barely moving, fading in and out of consciousness. EXE could tell he was trying and failing to disassociate… how pitiful. He almost felt bad for him. Almost. Not really. But, he didn’t want to waste any of his lives, so with a snap of his fingers, he made it so Knuckles wouldn’t truly pass out or die during this session. “This is a punishment, Knuckles. I can’t let you escape it.” “Huuuuhhhh…” he groaned in response, his hands twitching. EXE decided to just let him moan and groan, then wrapped a hand around his small intestine, pulling it out slowly and deliberately. He examined the organ, squishing it gently, turning it over in his hands, sometimes stretching it out. “Hnghhh…” “Oh, stop that.” EXE mumbled, flicking the side of the echidna’s muzzle. He barely registered it, his purple eyes half-lidded and unfocused. He continued to mess around with his organs- his large intestine, his liver, and his stomach. He really, really wanted to mess with his stomach acid, but that would’ve been too much of a hassle.  The blood loss was getting pretty severe, Knuckles must have lost at least 2 liters of blood by now. The echidna himself wasn’t looking too well either. He was barely struggling, just trembling in place. A thin sheen of cold sweat coated his body, and his chest rapidly rose and fell. His head was lolled to the side, his eyes glazed over, and shiny, wet streaks covered both sides of his muzzle. 

Without really thinking, EXE reached over and tilted Knuckles’s head so he was looking directly at him. He leaned in… and kissed him. He shoved his long tongue into his mouth, biting his lower lip hard enough to draw blood- wanting him all to himself. The coppery taste of his blood filled the echidna’s mouth. “Mh…” EXE was met with no resistance. After about 30 seconds, he leaned back, strings of saliva connecting both of their mouths. “What else to do with you…” he mused, looking over his captive. 

In a spur of the moment decision, he stabbed his right eye with the dagger, ripping the fleshy sphere out with ease. This got another half-scream, this one weaker but still satisfactory. He pulled the eyeball off of the blade and examined it. “You’ve got lovely eyes. What a nice shade of purple.” EXE complimented, turning the severed sphere left and right. He looked over at Knuckles, his empty eye socket leaking blood. Just then, EXE faintly heard him whisper something.

“What was that?” He leaned in so their black noses were touching. “K-kill… me…” the echidna begged weakly. He smiled once more, and poofed away the table, letting him fall onto his back. “Alright, alright. Let’s just make it fun for the both of us…” EXE didn’t even have to bother with restraining him. He flipped him onto his stomach, then went behind him and knelt down between his legs. He ran a gloved hand over his scarred back, feeling the tremors beneath his claws. EXE materialized a rope, tying it around Knuckles’s neck in a slipknot and grabbing his arm with his other hand. 

“Try to cum before your neck snaps.” With that, EXE pushed himself into Knuckles’s wet, trembling pussy, it felt wonderful as always. He used the rope as leverage to thrust into him, wet slapping sounds echoing throughout the dungeon. “G-uh–” Knuckles’s mind was a mess, the forced pleasure and loss of oxygen clouding his coherent thoughts. EXE thrust particularly hard, watching the echidna’s open stomach begin to give way. His intestines pooled on the ground, fleshy and glistening with blood. “Come on…” EXE gave the rope a yank. The echidna’s senses were completely scrambled- his hearing was muffled and his ears rung like nails on a chalkboard, his eye’s vision was blurry and unfocused. His mouth hung open with desperate gasps for air, his tongue lolling out and drool dripping to the floor. “You can do it…” EXE continued his brutal thrusting, his cock sliding in and out of his captive’s pussy with wet, grotesque slapping. “Hhhuhhh…” Knuckles’s free hand trembled, maybe trying to grab at the ground, maybe trying to scoop his organs back into his stomach, maybe… EXE gave a particularly hard thrust, his cockhead slamming against his cervix. 

That seemed to finally do it, Knuckles’s body trembled as he came. EXE smiled sweetly. “Good boy…” he said… before giving the rope one last yank. The sound of bone snapping echoed through the walls, piercing and final, as Knuckles’s powerful yet powerless body went limp in his king’s arms.
