Breaking Point

Soaking her ember scales in peace, Leann sighed and sank further into the bathtub, steam rising from the hot water as the 16 year old dragon girl relaxed and stretched her arms, lifting one leg out from the water for just a moment before quickly dipping it right back into the warmth of the bath. Sinking further in until only her face remained above the surface, she almost purred in pure bliss, fully enjoying her moment of morning peace as her feet gently paddled and splashed around, the fruity and fresh aroma of her soap wafting in the air. With all of her senses resting comfortably, the teen didn't even notice as the world continued moving around her and minute after minute passed by, the heavenly bath being the only thing in her mind. Leann's little swim was soon put on pause however, as the bathroom door swung open and slammed against the wall, her 13 year old brother standing behind it with a thoroughly annoyed look on his face, his eyes narrowed and an angry snarl showing off a few of his teeth, 
"Leann, c'mon! You told me you'd be in here for a few minutes, it's been half an hour already! I need to get to school in like a few dozen minutes and I haven't had a shower yet!" 
The girl covered up her breasts as she rose up from the water, giving the boy an irked sneer and a scoff, staring Adam down for a few seconds. The much smaller cub had the shape and features of a dragon, even having a pair of stumpy horns sticking out from his head, but most of his body was covered in dark brown fur that he had inherited from his fox dad, being only a half-brother to Leann and a hybrid, while her dad was a dragon. She finally shook her head with a dismissive smirk, sinking back into her bath, 
"Go pound sand, twerp."
"Seriously, I'm gonna go tell mom if you don't get the heck out of there!" 
With a twinge of fury in her eyes, Leann sat up and grabbed the side of the bathtub, growling and glancing at her sibling before she suddenly twitched, her face going blank and her eyes staring straight ahead for just a second. The teen had been implanted with a special chip in her head about a year ago, after being caught by the police for a fifth time in a single year, having been found drunk behind the wheel of a stolen car that was ploughed through a fence. The chip automatically suppressed a range of thoughts and actions deemed hostile, including violence, in an effort to make her less of a burden on the community and hopefully shed her delinquent ways. Leann quickly regained her senses, shaking the interference of the chip off with an annoyed grunt, pushing back the thoughts of what she was about to do to her little brother before laying back down, growling to the cub, 
"Get the fuck out and stop staring at me, pervert!" 
Furious at his half-sister's brattyness, Adam fumed at the doorstep for a moment, feeling an asthma attack coming on as he stormed away and slammed the door, utterly fed up with the way that she was treating him. 

After washing his armpits and his face in the downstairs sink since his bully of a sister had decided to hog the bathtub for the whole morning, Adam was finally able to leave from home and head towards school, grumbling and pouting the whole way there, having to jog the entire walk over since the fight between him and Leann had cost him almost the entire morning. Arriving just in the nick of time and taking a puff of his inhaler as he felt his throat tightening from the run, the boy was able to squeeze into the classroom seconds before his teacher was about to close the door, sitting down next to his best friend with a tired huff, still very obviously pissed off as he wiped his forehead and pulled his books out onto his desk, the friend leaning over and whispering quietly as the class started up, 
"Hey dude, are you okay? You look a little… annoyed." 
"No, I'm not okay, my sister was being a real butthole, again! I swear, the police really need to just turn that stupid little chip up to ten, force her to be nice for once in her life!" 
The cubs both turned back to their notebooks for a few moments, the friend thinking in silence for a few minutes before eventually giving the hybrid a gentle nudge, getting his attention once more and speaking even quieter than before, 
"You know… maybe you don't need to wait for the police to do it~" 
"What do you mean?" 
"There's this site, on the dark web, a forum, right? They've got all sorts of hacks and stuff, and someone just released a program that's supposed to hijack the commands being sent to those chips that are implanted in people. So you could like… take over your sister's chip and make her… I dunno… take a dump on the dinner table while your parents are watching or something."
Adam's best friend giggled as he sunk into his thoughts for a moment, 
"That program, it really works?" 
"Well, I haven't actually tried it, I don't know anyone that has one of those civil obedience chips. But apparently it does, yeah, based on what people are saying on the forum. I could show you how to get to that site, if you want to?" 
The dragon-fox seemed hesitant for some time, finally sighing and shaking his head, thinking that the idea seemed to go too far even if he did think that Leann deserved some sort of punishment, 
"Nah… I think I'm good."
"Alright, suit yourself. Just hit me up if you change your mind."
The boy's friend focused back on the teacher in the front of the class, leaving him to ponder alone, a hint of curiosity on his face. 

Struggling through the school day with several exams and quizzes dumped onto his head, the beaten and battered hybrid dragged his feet as he stumbled back home, the hard day at school only building up the roaring inferno in his chest, getting him ready to blow off some steam and relax by playing his video games. The boy had never been one to stand up for himself, usually backing down at the first sign of trouble due to his shyness and his less than impressive physical stature, not to mention his asthma, but even he felt his patience getting stretched incredibly thin in recent days as the constant needling and bullying from his sister wore him down little by little. He hoped that Leann might still be at her school so that she couldn't ruin his one chance at some peace, though he knew full well that she blew off most of her classes just so she could get home earlier, dread rising in the back of his head as he stood at the front door, taking a deep breath as he grabbed the handle and brought his key to the lock. Stepping inside, Adam stood still and listened carefully with his eyes closed, overjoyed at first since he couldn't hear any signs of the brat that made his life hell, a small smile finally spreading on his muzzle and his shoulders relaxing as he slipped upstairs, eager to get to some gaming before he had to bury himself in schoolwork for the whole weekend. He walked to his room and opened the door, immediately freezing in place with a furious look on his face as he saw his sibling sitting on his chair, her chin resting on her hand as she browsed the Internet on his computer, crumbs of cookies and other snacks that she had enjoyed littering the wonderful keyboard that he had just bought with his own money. The older dragon didn't even glance in Adam's direction before he finally let out a loud growl, tossing his heavy backpack against the floor and stomping his foot hard, 
"What the hell Leann!? Why are you on my computer, you have your own?" 
"There's something wrong with mine, I dunno, some viruses or something probably."
"Then go fix it and get off of my computer!" 
Leann giggled, 
"You go fix it, twerp. I'm using your computer until mine is good again."
The boy's tail lowered into an aggressive stance as he growled, his eye twitching and his hands balling up into fists as unbearable rage fought hard to finally break free, his angry gaze burning a hole into the back of the girl's head. She continued fully ignoring him as Adam felt his asthma rearing its head again, closing his eyes and grinding his teeth as he did his best to calm down, finally sighing and stomping over to his computer desk, grabbing his laptop before marching off as Leann smirked, 
"Oh, and get me a soda from the fridge, I promise I won't spill it all over your precious little computer, freak~" 
Slamming the door behind him, the cub grumbled under his breath, 
"We'll see who the freak is…" 
Sitting down on the sofa, he pulled out his phone as he opened his laptop, typing out a text message to his best friend, 
"About that thing we talked about at school today: I changed my mind, tell me where to find it."

After a few minutes of back and forth with his friend and downloading a few different things onto his laptop, Adam was set up with an illegal program to control his sister's civil obedience chip, a nasty and unpatched exploit allowing him to piggyback his own commands onto the wireless instructions constantly fed into the chip by the automated systems set up by the police. He took a few minutes to get acclimated to the interface of the program, having a few final doubts about what he was about to do, his moral questions quickly swept away as the sneering face of his older sibling entered his memory, his lips curling up to expose his fangs as he began writing up some very special code based on the examples shared on the deep web forums. With anger pushing him on, the boy stomped back upstairs, shoving his bedroom door open and setting the laptop onto his bed as Leann gave him an annoyed look, 
"What the fuck do you want now? I already told you to get lost, asshole!" 
With a single push of a key, the cub's code was run, his furious eyes glancing over at the girl as she stood up from her seat, 
"Did you hear me? Get the hell out, seriously! I'm g-" 
Cutting herself off, Leann's face twitched again before going blank for a few seconds longer than usual, a tiny huff making her nostrils flare as she held her breath before finally coming back to reality, blinking a few times. She was very experienced with how the chip's invisible hand felt, and she immediately knew that something had gone very wrong, her blackout lasting much longer than usual and her limbs feelings slightly tingly as she looked around in confusion, 
"What the hell… what's… what's going on?" 
She groaned and took a step towards her half-brother, about to say something when he opened his mouth first, an unusual smirk on his face, 
"Stop." 
Leann's whole body froze in place, the joints in her limbs locking up as she almost toppled over, grunting in discomfort and panic, 
"Wha… what did you do? What did you do to me!?" 
"I'm gonna do what someone should've done to you years ago: put you in your place!" 

Leann tried to struggle against her own limbs, straining and grunting as she attempted to will back the control of her body to no avail, realising that her younger brother had somehow tampered with the chip in her head. Adam let her panic for a few seconds, watching with a grin, happy to finally see the smug dragon be put down a peg. He wasn't satisfied with just giving her a small fright however, he had been planning revenge on the bully for years now, and her behaviour throughout the day finally broke the dam. The boy walked up to his defenseless sibling, pushing her onto the ground, taking in her shriek as she flopped onto the carpet with a hard thud, her arms and legs stuck on her sides. He squatted down and grabbed her by the collar of her shirt, pulling the girl up as he slapped her on the cheek as hard as he could, screaming in her face,
"How do you like it!? Are you sorry?!" 
Adam slapped her several more times, getting a pained yelp from her with every strike as he felt his heart beating faster and faster, his breaths starting to wheeze as adrenaline filled his veins. Stumbling back and almost falling onto his knees as he reached for his inhaler, Leann laughed at the cub through the stinging of her raw cheeks as he took several breaths of the medicine, 
"Seriously, you can't even beat me up while I can't fight back without looking so pathetic~?" 
Only further angered by her snide comment, Adam took a moment to catch his breath, deciding that he'd go as far as possible, ripping away any barriers and morality that still remained, 
"Fine, if you want to be a whore, then let's make you one. Strip!" 
Leann raised an eyebrow at her brother's order, startled as she stood up and her hands suddenly started moving on their own, stripping off her pants and shirt, taking off her bra while the boy got unclothed as well. She could see the direction that the encounter was going in, but she didn't want to show any signs of weakness, hiding her anxiousness by continuing to pepper the boy with insults and attacks. She saw the hybrid's cock, his shaft mostly reptile in shape but with a small knot at the base, his ballsack still tightly tucked right between his legs,
"Your balls still haven't dropped yet, figures. You're just a pathetic and perverted little kid!" 
Enraged by her, the cub grabbed the back of her panties and yanked as hard as he could, ripping the pair off as she grimaced and tossing them onto the floor, both siblings now fully in the nude. 

Still unable to move out of her own volition, Leann could only watch with a sneer as the boy disappeared from her field of vision, stepping behind her and bending her over slightly with a hand on the back of her neck, kneeling down and prying her legs open. He saw her glistening slit, a faint scent of her natural perfume in the air as he pulled her tail up to get a better view, huffing and slowly stroking his cock as he reached for a closer inspection. The girl let out a sharp squeal out of surprise as she felt his hand gently pulling her pussy lips open, quickly forcing her mouth closed to not give her brother any satisfaction from her discomfort, biting her tongue and trembling slightly as his fingers slowly dragged down from her taint to her clit. Adam hadn't ever had the chance to get an up close view of a pussy in real life before, still a virgin, now fully intent on losing that burden to his own sister to teach her a lesson on humility. He told himself that he was only doing what he was to punish his sibling, but he couldn't help but to feel a twinge of something other than fury and rage as he brought his slippery fingers up to his snout, getting a better whiff of her wonderful scent, feeling the slick substance gliding between his fingertips as he rolled his digits around, a few drops dripping onto his shaft. Shaking off the taboo thoughts he was having, the boy quickly wiped his fingers off on his fur and focused back on intimidating Leann, marching over to his nightstand and pulling out a bottle of lube, making sure she could see both it and his erect girth. Groaning and rolling her eyes, she did her best to seem unfazed, though a slight degree of nervousness still crept onto her voice, 
"C'mon, just… stop whatever the hell you're doing and let me get back to my day. I get it, you're pissed off, big deal! We… we both know that you're not gonna do anything, you don't have the balls for it!" 
"We'll see…" 

Adam glanced around, spotting his sister's backpack sitting on the ground, opening it up and pulling out her pencil case with a slight smirk. He zipped the case open while leaning back against his desk, slowly rifling through it as he barked out another order to her, 
"Spread your ass for me~!" 
Leann groaned as her hands moved to grab her ass cheeks, prying the buns open as she bent over and flipped her tail up onto her back, presenting herself to the boy no matter how little she wanted to do so. Eyeing up the teen's rear end, the hybrid grabbed a few rather large and thick markers from the pencil case, tossing the rest on the floor as he shook up the bottle of lube and gave the handful of markers a quick drizzle, spreading the slippery liquid all around before walking back behind Leann. With her holes exposed, the boy pushed a marker against her tailhole, rubbing the cold tip of the makeshift dildo against the rim of her hole, watching it twitch gently as she grimaced, her breathing getting more rapid by the second as the realisation began setting in that he might actually step over the line. With a hard shove, Adam forced the marker into his big sister's ass, getting a delightful panicked squeak from her before she managed to regain her composure, grimacing and only barely managing to keep herself from making any further vocalisations as he slowly twisted the marker around, sliding it in and out as his own shaft pulsed. Seeing that she was holding back the moans he was fishing for, the cub slipped a finger into her tailhole, stretching her slightly more open to cram in two more lubed up markers, watching them slide in until only a series of colorful caps jutted out from the dragon's flank, the final makeshift toy finally making her lose her cool and break out in a lengthy whimper, her toes curling up and the tip of her tail shuddering as she tried to endure the mixture of pain and perverted pleasure. Satisfied at finally forcing his bratty sister past her breaking point, the dragon-fox stood up straight and gave her plump behind a hard slap, watching her ass jiggle for a moment as she yelped sharply, leaving the markers sticking out of her tailhole as he moved to the next step of his revenge. 

Still bent over low enough to just barely see his smug look, Leann watched her little brother strutting to her front, his cock bouncing with every step until it was right in front of her muzzle, the manly musk of it lighting up her deeper instincts even though she had no desire to sleep with her own sibling, especially not while she had no control of her own body. Blushing slightly, she flinched as Adam grabbed her by the chin, his other hand laying flat on her head as he shoved her head all the way down to crotch level with him, forcing her on her knees, the markers shoved in her tailhole making her whimper quietly. The cub pried her maw open, her eyes flicking around in growing panic as she almost began hyperventilating, knowing what he had in mind but praying that the whole thing was simply a ruse to make her regret her bullying ways or even just a nightmare. To Leann's dismay, she wasn't sleeping and the hybrid's plans were not mere bluffs, his forked tongue just barely sticking out as he inched closer to his sister's lips, 
"Since you love running your mouth so much, you can open up wide for me~!" 
Unable to even try to struggle, the girl had no choice but to close her eyes in disgust and whine as his cock pushed inside of her maw, the pulsing and throbbing shaft gliding on her soft and slender tongue as he moaned, slowly thrusting deeper and deeper until his hybrid knot bumped up against her lips. Though he wasn't the biggest guy that Leann had seen, her inexperience with taking males in her muzzle was still making his length difficult to handle for her, the tip poking against the base of her tongue making her gag as her eyes filled up with tears. Feeling her wonderfully silky mouth enveloping his manhood, Adam leaned over his sister and began humping her muzzle, starting off slow with just a steady grinding but quickly picking up the pace until her nose was bumping against his crotch several times a second, her throat getting plunged by the boy's girth, leaving her very little time to get any air in between the pounding and her desperate chokes. 

Fucking her sister's face in a frenzy, Adam felt his emotions storming uncontrollably, a mixture of pure rage and lust growing to heights that he hadn't ever experienced before, years and years of deep seated hatred and repressed desire all boiling over and erupting at once. He yanked his cock out of Leann's maw, gripping her throat with both hands and shoving her onto her back as she was still gasping and coughing, her body frozen stiff as he pried her legs open before sinking his girth into her wet mound, in his fervour completely forgoing the bottle of lube for the slickness of her own spit. The dragoness wailed and grunted as her brother laid down on top of her, ploughing into her pussy and immediately knotting himself inside of her, a small lump bulging in the girl's belly before he yanked his knot out, using his entire length to fuck her. Adam's knot wasn't quite as large as a true canine's, being only a half-canid himself, but it was still girthy enough to make his half-sister moan every time it split her pussy lips wide open, her hoarse voice rising and falling in tandem to his thrusting. The cub's hips didn't stay still for even a moment, spit and drool flying everywhere as he growled and grunted like a feral beast, losing all control of himself, feeling lightheaded from both the intensity of the moment as well as his asthma, even his closing airway not giving him any pause. Raping his older sister until he could barely even breathe, Adam finally tied her cunt once and for all, his claws tearing up the carpet as he roared and fired off his load into her womb, uncaring of what the end result of it might be, the only thoughts in his head being those of domination and revenge. With her brother going limp on top of her, Leann took a few shuddering breaths with a grimace on her face, sniffling as she felt his cum gushing through her cervix, his seed being the first to touch her womb. 

Adam pushed himself off of his sister, rolling off with a huff and closing his eyes as his cock slowly softened up, stumbling to his legs to grab his inhaler. He took a few puffs of it as he stared down at Leann, a puddle of white slowly spreading between her legs, her eyes half lidded and looking away from him, shame burning on her cheeks. The boy grabbed his phone, tapping it a few times before squatting between her legs, the flash of the camera blinding her as he took a few shots of the teen's nethers, making sure to include her creampied mound, the markers stuffed up her tailhole, and her horrified expression in each of the pictures. With the photos safely stored away, he walked back over to his laptop, tapping a key as he stared down the dragoness, his furious glare only making her more uncomfortable as an awkward silence filled up the bedroom. A few seconds later, Leann felt her limbs starting to relax, a heavy sensation of pins and needles overtaking them before she could move them once more, groaning in discomfort as she sat up. Adam didn't bother looking at her as he walked away, only stopping at the door for a second, 
"If you tell anyone, I'm sending those photos to everyone that you know, and I'm telling them what a whore you are."
With that, the cub slammed the door and left Leann alone, her sore body complaining as she rolled to her side and gently pulled the markers out from her asshole, whimpering before curling up on the floor, trying to gather up her strength enough to get up and into the shower. Opening one eye and staring at herself on the mirror on the opposite side of the room, she couldn't help but to grin slightly, impressed at Adam finally standing up for himself in such a remarkable way, her hand shaking as she reached down between her thighs to wipe away a glob of cum leaking from her slit.
