The Guardian Collars

Walking through the busy city streets, Lucky marched towards his destination, eager to get to spend some time with his older brother again. The 13 year old fox had been tasked with assisting his sibling on a very important mission, as they were both members of the Guardians, a group of heroes and adventurers who made it their goal to safeguard the world from anything that might threaten it. The cub hadn't yet been told what exactly he and his brother were going to go up against, but he was amped up and ready to rumble no matter what he might have to face, anxious to get out and be a hero once more after resting for a while since his last adventure. The boy's brother, Lucas, was nearly twice his age and a fair bit more experienced when it came to the Guardians, so Lucky had always viewed his big brother as a sort of mentor, happy to take any opportunity possible to hang out with the canine whenever he could. Too wired up to even just walk, the teen jumped to a slight jog, soon speeding up to a full on sprint as he headed towards his destination, zipping past people and weaving through crowds until he finally spotted the building he had been on the lookout for. Stopping in front of the small house, Lucky bent down and leaned against his knees for a moment, panting and wagging his tail as he huffed, reaching up to press the doorbell. There was a slight shuffling coming from inside, getting louder until the door finally opened a few seconds later with Lucas poking his head outside, seeing his younger brother puffing at his doorstep, 
"Lucky? Why are you so winded, is something wrong?" 
"N… no, not at all! I came here as fast as I could!" 
"I… I see that, a bit too fast actually. Didn't Lyra tell you that we'd be leaving tomorrow?" 
"Yeah, but… we can't put off fighting evil until tomorrow, right? Best to head there immediately!" 
"I can appreciate the enthusiasm, but our ride won't be here until tomorrow. So unless you wanna run to the other side of the world, we're definitely going to wait until tomorrow."
"Oh…"
The older fox sighed with an amused smirk, shaking his head before stepping back and opening the door wider, 
"Alright, get inside, I guess I'll fix you up a bed on the sofa or something."
With a slightly sheepish expression on his face, the cub slipped inside, having let his enthusiasm get the better of him once more.

With the siblings settling in for the evening, Lucas brought some blankets and pillows for the sofa, laying them down for a makeshift bed so that his younger brother could spend the night there before the pair were supposed to head off the next day. As it was already getting rather late, the sun setting down soon after the brothers had enjoyed a meal, both Lucky and his big brother stripped down to their sleepwear. The older canine chose to go with just a pair of boxers, but Lucky was used to sleeping in his pyjamas, though he hadn't brought them over since he hadn't been expecting to sleep over at the house. Feeling slightly chilly in just his undies, the boy gave Lucas a soft poke on the shoulder, 
"Hey, uhh… do you have any pyjamas I could borrow?" 
"Pyjamas? No, I don't think so, been a while since I've bothered with those. I guess you could just sleep in your t-shirt, or borrow one of mine if you don't want yours getting all sweaty." 
Lucas pointed the teen towards the back room while trying unsuccessfully to hold back a yawn, sitting down on the sofa to watch some TV while his little brother disappeared into his room. Pushing the door open, Lucky stepped into the humble bedroom, looking around in slight awe as all sorts of Guardian relics and high tech gadgets scattered the place, keepsakes of Lucas' past exploits. The boy spent a few minutes poking around the mementos, starting to feel slightly jealous of how his sibling had gotten to play with all manner of exciting toys, hoping that he might get a chance to do the same soon enough. Remembering why he came to the bedroom in the first place, Lucky turned to a closet sitting in the corner of the room, opening it up and humming quietly as he flicked through a few stacks of pants and tops, finally pulling out a red t-shirt and pulling it on, the slightly oversized shirt going all the way down to his crotch. Happy with his makeshift pyjamas, the kit was about to close the closet and rejoin his brother when he noticed the light catching on something shiny tucked right in the corner of it, his tail rising in curiosity as he glanced over his shoulder before diving back in, pushing aside a few jackets and boxes that seemed to have been put there to try to hide the object of his interest. Lucky pulled out a small metal briefcase with the Guardian symbol on the front of it, laying it down on his brother's bed and opening it up to find a pair of collars and a remote. He grabbed one of the collars to examine it further, seeing that a tag dangling down from it had the guardian symbol once more, the material of both the collar as well as the lock that kept it closed seeming much more sturdy than any normal collar that he had ever seen. 

Intrigued with his find, Lucky slipped the collar back into the briefcase and hauled it into the living room, wanting to ask his brother what the set was, hoping that it might've had something to do with their mission. Stepping out, the cub was met with a soft snore, turning his head to the couch to see Lucas passed out cold and splayed out on the bed that he was supposed to be sleeping on, the man seemingly having been a bit too tired when settling down. Lucky thought about waking his sibling up, but figured that it was for the best that he let the fox snooze, sitting down in front of the sofa and setting the briefcase down on his crossed legs, thinking that he could figure out the mystery all on his own. He snatched one of the collars and inspected it in the light for a few moments, thinking the glimmering little trinket looked cool, watching himself in the mirror as he finally put it around his neck, clicking the lock shut. He made sure that he could still open it, admiring the Guardian symbol on it as he smiled at his figure staring back at him, feeling much more proud. The cub glanced back at his brother with the other collar in his hand, hesitating for a split second before grinning gently, carefully sneaking up on the sleeping Lucas to slip the collar around the man's neck as well, thinking that his older brother would look funny when collared up like a kit. Having to hold back his snickers as Lucas snorted and rolled around, the tag on the collar clinking around like a bell, Lucky finally turned his attention to the final piece still left in the briefcase. He pulled out the remote, very gently turning it around, staring at the power button on it, hesitating even touching it. He had no idea what it did or if it even interacted with the collars in any way, but he did feel slightly nervous about fiddling with it since it seemed to be deliberately hidden by his brother for one reason or another. The boy had seen examples of advanced Guardian technology that would be devastatingly dangerous if used improperly, but surely a simple pair of collars and an odd remote couldn't be anything too risky? 

Unable to contain his curiosity, the kit finally pushed the power button and felt his heart skip a beat as the remote bleeped to life, a screen lighting up and displaying two options, Lucky's eyebrow raising up in confusion as he whispered the options out loud to himself, 
"Unlock and… interrogation?" 
With his tail wagging and his ears flopped down in intrigue, the kit stared at the two options and tried to figure out what they could've meant, peeking back into the briefcase and running his hand across the lining to make sure he wasn't missing some part of the machinery or some sort of instructions, coming back empty-handed. He hummed quietly, hovering his fingers over the pair of buttons before finally closing his eyes and pressing the "unlock" option, bracing for something to happen, clutching the remote tightly. After waiting around for a few second, he opened one eye and shrugged, confirming that everything was exactly the same as before, 
"Huh, maybe it's just busted or something…" 
Much less careful than before, Lucky threw caution to the wind and poked at the second button, expecting a similar result when suddenly he felt an odd tingle around his neck and heard a small click, the tags on both collars glowing with a dim blue light as he felt tiny sparks and jolts up and down his body, an electronic voice from the remote announcing calmly, 
"Level one."
The sudden effects startled the fox enough for him to accidentally drop the remote, flinging it high into the air and letting it come straight down on the corner of a coffee table as he yelped before clamping his muzzle shut, turning to his thankfully still asleep brother. The cub grabbed at the collar and tried to open it, getting slightly panicked as he noticed that the lock had been engaged, not budging no matter how hard he tugged at it. Remembering the "unlock" option, he dashed for the remote, picking it up from the ground and noticing that the screen had been shattered, hearing a small rattle coming from within as he turned it around. He frantically tapped at the cracked screen and hammered at the power button, doing anything he could think of but receiving no signs of life from the broken remote, sweat running down his temples as he gulped nervously, unsure of what he had just done or how he could undo it. 

Still trying to yank at the collar, Lucky suddenly felt the tingling and the sparking going away, replaced with a very different yet very familiar sensation in his nethers, his eyes widening in panic as he looked down to see his underwear tenting quickly, the boy's dick sliding out of his sheath. The kit looked over at the older fox to confirm his worst fears, seeing Lucas already sporting a huge erection, softly panting and humping the sofa as the man's dreams seemed to steer into a new direction, slobber leaking down onto the pillow as the front of the brother's boxers grew wet from precum. Lucky noticed a similar stain appearing on his own underneath, sitting down on the corner of the coffee table and whimpering gently, clenching his teeth as his knot popped loose from his sheath. He had to pull his undies off to the side and let his red rocket flop free, sighing in relief as the stiff shaft quivered in the cool evening air, a few drops of his musky essence spraying onto the carpet as he continued fiddling with the lock of his collar. He knew that the erections were somehow caused by the collars, but he didn't understand why, unsure of how getting hard would help in an interrogation of someone. The boy stared at his cock, slowly reaching down and wrapping his hand around his base, gasping as quietly as he could manage as he squeezed his length, milking a few more drops of pre as his balls twitched. Trying to think of some way out of the predicament he had caused, Lucky hoped that maybe if he took care of the awkward situation throbbing between his thighs, then maybe the collar would be satisfied and come loose. He kept one hand massaging just below his knot while stroking the rest of his dick with the other, turning around from his brother as he moaned under his breath, both foxes working on their wood simultaneously, though one was still dead asleep. The cub wasn't sure if it was just another effect of the collar or because he hadn't touched himself in nearly a week, but he felt much more sensitive than usual, only needing a few minutes before he felt that he was on the verge of giving the walls of his brother's apartment a fresh new coat of paint. With a warbling whine, the kit stood on tiptoes and spread his legs apart, aiming his cock with both hands as it quivered, but the orgasm he was now desperate for never quite came. With frantic groans and sweat pouring down his back, the boy kept pumping to no avail, always feeling his relief just barely slipping through his fingers as he teetered on the edge, leaving him with a horrible case of blue balls. 

Nibbling on the corner of his pillow, Lucas continued grinding and humping the sofa as his dreams only intensified, his tail shivering and his voice trembling as he moaned in his sleep, unaware of what was happening around him in the real world. Frowning and seemingly also getting very frustrated at not being able to get off, the man hugged his pillow and kept ploughing his imaginary partner, rolling his rock hard cock around between the cushions and his belly. The siblings both tried desperately to blow their loads, grunting and panting until the smashed remote flickered back to life once more, the electronic voice from within calling out with heavy static, 
"Level two." 
Lucky felt his body freezing up stiff, his joints locking up and his muscles tensing, leaving him trapped for a second before he suddenly began moving again, only this time he wasn't in control. Lucas experienced the same thing, finally stirred from his slumber, confused and dazed as he nearly flopped onto the floor as he stood up, all without any say from him, 
"Wha… what's going on, why can't I move?! Lucky? What are you… why are you naked, wha…" 
The teen gave him a shy look as he noticed the collar hanging on Lucky's neck, quickly realising what had happened as he angled his eyes down to confirm that a similar band was strapped around his own neck, 
"Oh for… d… do you still have the remote?" 
"Kinda…" 
The boy motioned towards the floors with his eyes, pointing towards the broken remote as his big brother stared at it with a mortified expression, 
"Oh no…"
Before the man could finish his sentence, the pair were sent into one another's arms, stumbling back onto the sofa. 

Lucky's legs pushed him against his older brother's chest, landing right on Lucas' lap as the duo yelped in surprise, able only to watch as their hands moved without their input. The cub had barely recovered from the crash when his hands were already rubbing and kneading his sibling's chest, caressing the man's belly as his rock hard and bare cock quivered against the other canine's erection, a mortified look on his face, 
"What the heck is happening!? Why are the collars doing th-" 
Right in the middle of his sentence, Lucky's maw plunged forwards and his lips locked with his brother's, both foxes moaning frantically as they were forced to kiss, their tongues intertwining. Lucas knew what the collars were capable of, but he wasn't sure what programming his little brother had accidentally turned on, or if the broken remote would still function as expected, unsure of whether he should hope for a malfunction that would risk both of their safety or for the stages to proceed as normal which would risk their dignity. Though he knew what to expect, he still couldn't do anything about any of it, watching helplessly as his arms moved on their own while he was forced to make out with Lucky, his hands pulling his boxers down and massaging both of their cocks together while the cub humped him. Lucky squealed into his sibling's maw as the bigger canine coated a finger in his precum before dipping it underneath his tail, finding his asshole slowly working it inside, the collar forcing him to sit down on the digit to drive it deeper. The boy tried to regain control of his body, but every attempt at fighting back against the collar only sunk his tailhole another inch down on his brother's finger, his legs quivering as Lucas grabbed the base of his tail and added another digit into his hole, his tight ring flexing hard around the intruding fingers as he kept humping, every thrust forwards grinding the sibling's red rockets together while the return pushed him back down on his brother's hand. 

Straining and whimpering as the constant edging sapped the energy from the pair, the brothers could only look at one another shyly and apologetically as they were kept in one another's arms by the collars, their hands kept busy while they frotted. Lucas thought several times that he might finally get the sweet relief of an orgasm, feeling the building pressure in his loins reaching a crescendo before always being pulled from under him at the very last split second, keeping him not only ashamed but frustrated as well. Just as the duo thought that their night couldn't get any worse, the sputtering remote coughed up one last stuttering line as a few sparks glinted in the dark, 
"Level three."
Lucas grimaced, praying that nothing would happen, horrified as his feet pushed him off the sofa and brought him towards his TV, his little brother staying behind while jerking off and fingering, gasping in between a few moans,
"Wh… what's happening now? What is it making you do?!" 
Buck naked, Lucas feared the worst as he reached down to the laptop connected to his TV, turning it on and navigating to the video call, 
"I really hope it's not gonna do what I'm thinking…" 
With a flick of a finger, he turned on the webcam and started a call with every member of the Guardian team before hopping back on the sofa with his sibling, the two quickly grabbing each other's shafts as their sister, Lyra, appeared on the screen, seemingly distracted for a second before glancing over at their image, 
"Hey, what's up, something wrong? You don't usually call this… OH MY GOD!" 
One by one, the rest of the team appeared and exclaimed as they saw the brothers pleasuring one another, causing the duo to quickly go beet-red, their knees spread wide open to give as good of an angle for the webcam as possible. 

Lucas tried to shut out his friends' horrified yells as he felt his little brother pulsing in his hand, hoping that the interrogation sequence would be over soon enough, praying that it was all nothing but a nightmare. Unfortunately for him, it was all very real as he would quickly find out, the collar suddenly ordering him on his hands and knees on the sofa, his tail lifting up and one hand reaching back to spread his cheeks wide, his hole staring the cub right in the face. Both males, as well as their audience, all realised what was happening on the same heartbeat, both foxes going pale as Lucky was pulled up to his knees, shuffling behind his brother and grabbing an ass cheek while pushing his drooling tip up to the virginal pucker, giving the man only a moment to prepare before plunging straight inside. Lucas howled before clenching his teeth, trying not to shame himself any more than he already was, blushing as he saw his sister covering her mouth on the TV. The cock in his tailhole slid inside fairly easily thanks to the slippery coating of precum as well as the boy's slightly smaller size, though it still didn't feel particularly gentle to the man who hadn't ever tried anal before, his own pre pooling on the couch as he groaned into his pillow. Lucky was similarly ashamed but also rather amazed at how the older fox's asshole was clenching around his length, seeing stars as his knot was flirting with his brother's donut, his maw open in a silent scream as he pounded away. 

The two siblings were made to fuck right up to the point of utter exhaustion, not allowed a moment to catch their breaths, kept hard and on the edge by the collars. Through the sweat and the whimpering, Lucky felt the pace constantly speeding up, building towards a big finish as his lungs struggled to keep pace, his grip on his brother's ass nearly faltering as the tailhole around his cock spread wider. His knot was getting slightly deeper with every passing minute, finally slotting inside as the canines broke out into howls and yells, the control of the collars giving way and letting them do what they had been so hungry for. Both foxes erupted as Lucky doubled over against the man's back, his balls pulling close to his body as he fired off a huge load into his brother's tailhole, feeling the tight ring hugging his knot and sucking in every last drop of his load. Lucas meanwhile sprayed his seed all over the couch as well as his own belly, his shaft flicking upwards with every rope of cum, his face twisted with pure pleasure no matter how much he would have liked to hide it, able only to moan in relief after having to hold back for hours. The brothers collapsed on top of one another, too tired to move a muscle as their team stared at them in silence, only their heavy panting to fill the night until a tiny metallic click echoed off the walls and the locks on both of their collars opened up simultaneously. Neither fox knew what to say to the other Guardians, nor could they even try even if they did, forced to stay tied together as they gasped for air until passing out soon after, the task of explaining the shameful event left for the following morning.
