Bratty Blackmail

Groaning and swaying from side to side as she sat in the tiny waiting room of her school's nurse, Carly's hands squeezed the armrests while she chirped pitifully, occasionally opening one eye to take a quick peek around the room before getting back to her suffering. The 11 year old canary had only come to school an hour ago, dropped off by her parents before they left for the train station, leaving her and her older sister home alone for the rest of the weekend. The bird was wearing a t-shirt and shorts, the cap on her head nearly tumbling off as she slouched forwards, holding her belly and whimpering as she kicked her feet around. Her plumage was mostly pure white, with a tiny bit of light yellow peeking out from her chest and shoulders, mostly hidden by her shirt. After having to wait around for a few minutes, the nurse's last patient finally left and Carly was called into the office, the gazelle inside watching her stumble in, barely able to take a single step without falling over,
"Oh dear, are you feeling unwell?" 
The cub simply nodded and moaned, plopping her flank down on a seat at the edge of the office as the nurse leaned down next to her, gently taking off her cap and feeling her forehead, 
"Well, you don't seem to be running a fever at least, can you tell me what's wrong?" 
"My head hurts a lot, and I've got these really weird shapes in my eyes!" 
"Hmm… that sounds like a migraine, have you had them before?" 
The young bird nodded with a sad chirp as the gazelle grabbed a plastic mug, pouring it full of water before grabbing a painkiller from the medicine cabinet, handing them both to her, 
"Well, there's unfortunately not much to do besides taking this and getting some rest. I'll tell your teacher that you'll be leaving early, do you think you can make it back home by yourself or would you like me to call your parents?" 
Carly threw the pill into her beak and took a small swig of the water before shaking her head, 
"I… I can make it home, the bus stop is really nearby."
"Alright, you just try to rest and keep drinking water, I hope you feel better soon!" 
"Thank you."
Looking dejected and like she was about to topple over, the canary stepped out of the office, closing the door behind her and perking up the moment she was out of sight of the nurse, a sly smirk on her face as she waltzed out as if absolutely nothing was wrong with her. Passing by a trash bin, she slipped the pill she had been given out from underneath her tongue, spitting it out of her beak before giggling as she quickly scampered out the side exit of the school, trying not to be seen by any of her classmates or teachers. 

Walking over to the next bus stop over rather than waiting at the one right in front of the school just in case anyone spotted her, Carly boarded the bus headed towards her home and gave the driver a smile as she handed him a few coins, humming cheerfully as she skipped into the back, getting a prime seat in the near-empty bus. The cub knew that her parents as well as her sister, Lyn, were all supposed to be away, with her sibling being at school and her parents leaving for their trip until the start of next week, which meant that she could have the house all to herself, getting an early start to her weekend. Carly had become rather adept at pulling off her cons, able to fool both the school nurse as well as her mom to skip school almost as much as she wanted, though she knew that she needed to be tactical and not abuse her skills in deception too often, not wanting to rouse suspicion. She couldn't keep herself from running her scam on that day however, as she knew that her sister had just gotten a bunch of new movies, most of which Lyn wasn't willing to let the girl watch since they were apparently too adult for her. Not accustomed to taking no for an answer, the bird came up with the plan to get out from school only a moment after being dropped off, giving her older sibling enough time to also leave their home while simultaneously leaving her with plenty of time to watch at least two or maybe even three of the movies while enjoying some snacks. Grinning at her own deviousness, Carly sat back with a sigh and relaxed for the rest of the trip, watching the view from the window before the bus came to her stop, hopping off and hoofing it the rest of the way home. 

Carly strolled along, singing and trilling as she hauled her backpack, enjoying the morning sunshine while taking the short walk from the bus stop back home, fishing out her keys as soon as the house was within eyesight. Not thinking twice, the girl headed straight inside and kicked off her shoes, not noticing that her older sister's coat was still hanging right where she had spotted it that morning, with another coat that didn't belong tucked right alongside it. Oblivious to the signs that she might've not been quite as alone as she would've liked, the canary belly flopped down on the sofa with a sigh, giggling as she bounced, rolling onto her back and crossing her legs as she enjoyed the silence and the calm of the house, her chances to relax in such peace generally being very few and far between. With her hands resting under her head, she closed her eyes, able only to take a few breaths before the quiet of the household was broken by some odd murmur coming from upstairs, the cub's eyes immediately shooting back open. She sat up and cocked her head, twisting and turning from side to side as she tried to find the source of the sounds, confused since she was sure that the place was supposed to be empty. Thinking that maybe her sibling had accidentally left the TV or the radio on upstairs before leaving, Carly pushed herself off of the sofa and headed up, furrowing her brow in confusion as the muttering became much more clear the closer to her sister's room she was getting, still too quiet for her to make out but distinct enough that she knew it wasn't coming from any electronics. Crouching down slightly and making sure that she wasn't making too much noise, the cub snuck up the stairs and into the hallway, getting right up against her sister's bedroom door and confirming that the conversation was happening inside, gently pushing the door open just a crack as her curiosity overwhelmed her. Lyn was standing in front of her mirror, her upper half in the nude, gently pruning her head and chest as she giggled, the 17 year old's bright yellow feathers lighting up the whole room, a few of them strewn around the floor and her bed. Also on her bed was a boy that Carly hadn't ever seen before, Tony, a rather toned husky a few years older than Lyn, dressed only in his underwear, plucking a lone yellow feather out of his fur as he grinned. 

Lyn turned around, flashing a smile to the canine as she stretched and sighed, 
"You sure they're not gonna miss you at work?" 
"Nah. Even if they are, so what? I'll get a new one at some other garage before I give up a whole day with this sweet piece of ass~" 
She giggled and sat down next to Tony, running her hand through the fur on his chest before he grabbed her arm, tugging her down against him while setting his other hand on the back of her head, pulling her in for a kiss. Scrambling around on top of the boy, the canary was finally let go as she playfully slapped his chest, wiping her beak of his slobber, 
"Tony~! I just got done cleaning up after you messed my feathers."
"Well, then I guess I gotta mess 'em up all over again. C'mere~" 
She giggled as the dog pulled her down, squeezing her tight while tickling and fondling her slim body, giving her flank a light slap as his boxers began tenting up. It seemed as if Lyn had coincidentally had pretty much the same idea as her younger sister, except instead of sneaking out of school to watch movies, she decided to invite over her new boyfriend to have some stealthy fun with no one around, or so the duo at least thought, unaware of the two curious eyes peering into her bedroom. Carly closely followed the pair's fooling around, holding back laughter as she spied on her sister and Lyn's apparent boyfriend, already trying to think up of how best she might take advantage of the situation, coming up with an idea to squeeze the older girl for some ice cream and other treats under threat of telling their parents about Tony. She was about to barge inside and make her presence known when she saw her sister stripping down to just a pair of pink panties, watching as the husky cupped a handful of Lyn's backside, grinding his erection on the bright yellow avian's cheeks. Stopping in her tracks, the cub stared at the sight as the pair made out, her breath getting caught in her throat. 

Tony pushed his bulge up against his girlfriend's crotch as he pulled her panties up to get a good look at her mound, her lips shining through the pair as his tip rubbed up all over her pussy, his precum leaking through his boxers and staining her underwear as Lyn moaned and chirped softly, tucked under his chin. Carly didn't really have much of a clue as to what the two lovebirds were doing, but she felt an odd tingling all over her lower half as she spied on the pair grinding and humping together, having to hold back a squeal as her knees pressed together. With her eyes still glued to her sister and the male, she reached down to try to scratch the odd itch that had overtaken her, the girl's fingers roaming all over her legs and her lower belly before brushing right over her slit, a tiny squeak accidentally escaping her beak as she quickly clamped it shut with a horrified look on her face. Thankfully for Carly, the younger bird's exclamation was covered up by Lyn's gasps as she slipped a hand between her and Tony, simultaneously sliding both of their underwear down until his red rocket slapped up against her cunt, the shaft squeezed between her lips like a hotdog in a bun. Panting hard, she rose up just enough to get his tip nestled safely in her warmth before plunging back down into the dog's embrace, her drawn out moans accompanying his slow thrusts as he drilled the teen's slit, both able to take it a bit slower and enjoy the moment much more after purging the worst of their built up pressures on one another during their first fuck of the day only slightly earlier on during the morning. Carly kept rubbing her hand against the spot right between her legs that she'd discovered, her other hand wrapped around her beak as she whimpered quietly, leaning against the wall to keep herself on her feet. She couldn't really tell if what she was doing was actually helping or only making her itch worse, but she knew that she certainly liked how it felt, deciding to see if the experience would be any more intense without her clothes being in the way. The cub tugged her shorts down to her knees before peeling off her panties, the pair adorned with pictures of princesses and princes, the front of them plastered with her juices. Pulling the panties down just enough so that she could plunge two fingers against her mound, she nearly lost her cool and gave herself away again, having to squat down and stifle a moan with all of her will as her digits pressed against her sensitive folds, a tiny squirt of her nectar spraying all over her thighs, matting her white feathers together. 

Licking at his girlfriend's neck as he slammed her flank down against his cock, Tony squeezed his knot inside of the bird, both straining as it slowly stretched her open before finally slotting inside like a cork, Lyn's moans whipping him into a frenzy as she continued bouncing on his lap the whole time his balls unloaded inside of her. Carly whimpered with every stroke of her fingers, gliding them between her lips as she bucked against her hand, revelling in her discovery of the new fun activity, letting her body tell her what to do. She accidentally bumped her palm against her clit, falling onto her knees while screaming silently, getting tunnel vision as she stared at her older sister's slit tied and dropping with cum. Focusing her fingers on the small bump, the girl kneaded and massaged until her eyes shot wide open and her fingers were forced inside of her pussy, her hips humping back and forth on their own as she came for the first time, squirting all over the floor and the door. In her ecstasy, the cub forgot all about the fact that she was supposed to be hiding, squealing out loud and collapsing forwards, knocking the door wide open just as the intimate pair inside both turned to look at what the sound was that startled them, seeing the girl on all fours with her pants pulled down and her hand still stuck between her legs as she howled in pleasure. Halfway through her own orgasm, with a knot stuffed down her mound and jets of cum gushing into her womb, Lyn squeaked in surprise, 
"C… Carly?!" 
The two siblings stared at one another in awkward silence, Tony's gaze switching between the two in confusion until the younger girl finally let out a meek gasp, 
"Hey…" 

Trying to shake off the shock of the sudden interruption, Lyn pulled a blanket to cover up her and her boyfriend's situation before scowling at her little sister, pointing as she growled in annoyance, 
"What the hell, Carly!? Why are you home already? And why were you spying on us? And why are your pants down?!" 
As the barrage of questions continued, Carly struggled to stand back up, her entire lower half still feeling like floppy jello after going through her first orgasm. Grabbing onto the door frame and groaning gently as she pulled herself up, the girl looked down to see her panties and shorts utterly soaked through with her honey, letting the soiled clothes drop down and kicking them off before focusing back on what her sister was saying to her, listening to the teen yelling about privacy and knocking while she rolled her eyes. Tony still didn't quite get what was going on, his eyes getting caught on the cub's bare lower half, neither of the two birds seemingly minding that she was standing right in front of him with her arms crossed and her legs spread, a drop of her juices glistening right against her clit, making it very difficult for him to get his knot to go down. He could see that the siblings were having some sort of an argument, but he couldn't quite pay attention to it, trying his best to hide his interest in his girlfriend's underage sister. The argument ended with Lyn scoffing and telling Carly to get out of the bedroom, the young Canary standing still for a moment before replying to the request with a smug look on her face, 
"No~"
"Excuse me?" 
"I'm not gonna leave, you can't make me. Cause if you do, I'm gonna tell mom and dad about you two~" 
With her chest puffing up and her tail feathers perking up in a cocky show, Carly stepped into the bedroom, 
"And I wanna do that stuff!" 
Tony blinked a few times, 
"What?" 
"That stuff, like you're doing with my sis. It looks fun, and I wanna do it too, and I'm gonna tell dad if you don't let me~!" 
He looked at the older avian with a slight worry in his gaze, the yellow canary's shrug giving him a confirmation that the girl might not have just been bluffing or joking. 

The pair spent a few moments whispering as the mischievous cub tapped her finger impatiently, giving the husky a small smirk as he tried not to let his girlfriend know just how excited he was at the thought of getting to play around with the girl, Lyn finally sighing and waving her over, 
"Alright, fine, c'mere!" 
Carly smiled and hopped up right alongside the male as Lyn tossed the blanket off of her and the canine underneath, grabbing onto his knot and gently twisting herself around to get it loose from her lips, letting out a tiny chirp as it popped loose. The cub watched eagerly as Tony's load oozed out of her older sibling, her eyes glimmering at the lewd sight, her hands immediately sinking right back to her own nethers. Lyn stayed on her knees, hovering right over her boyfriend's shaft as she sighed, 
"If you're gonna be such a little brat, at least help me out here a li'l. Clean me up."
"Uhh… how?" 
"With your beak, hurry up, geez." 
Eager to continue her experimentation, Carly crawled over on her belly and plopped her head down next to the older bird's and the canine's crotches, getting a good sniff of the wonderful musk as she leaned up closer, carefully poking her tongue out to meet her sister's pussy lips. Lyn moaned sharply before settling into a long huff as the cub's curious tongue dug into her mound, seemingly rather fond of the taste of her boyfriend, lapping up the globs of cum that he deposited in her without any questions. Tony held his breath as he watched the two girls on top of him, his cock twitching whenever Carly's panting or his girlfriend's drippings tickled it, his attention slowly shifting to the white canary's undercarriage, her deliciously plump pussy staring him right back and begging for some attention. The girl squeaked softly as his fingers caressed her slit, her feathers puffing up as she pushed her maw further into her sister, both of the birds moaning harder as his digits slowly reached deeper into her pussy, stopped soon by her hymen. 

Salivating at the opportunity to pop the tiny girl's cherry, Tony pulled his fingers out of her and gave her sap a quick test with his tongue, dipping a digit into his maw and smirking slightly at just how similar she tasted to her older sister. He gave her flank a quick pat as he shuffled out from under Lyn, his cock still wet from the older avian's mound as he got up on his knees, 
"You wanted to try it out, right? Well, what are you waiting for~?" 
Carly looked back at him in glee before quickly flopping down onto her back, kicking her legs off to the sides as she rested her head on her sibling's lap, Lyn's hands gently caressing and petting her as the husky got into position at her lower half. She giggled and squirmed around slightly as the boy's tip slipped around between her pussy lips, struggling to get inside of the tight and drenched hole, finally burrowing inside with a little help from the older sister. Carly laid back and closed her eyes, chirping softly as she felt the girth entering her, thinking she'd already experienced it all as the canine shaft bumped up against her hymen. Recognising what was going to happen, Lyn grabbed onto her arms and gently held her down as Tony braced for a harder thrust, letting the girl take a few breaths before ramming forwards and taking her virginity once and for all, the sting of her deflowering only hurting for a few seconds before it was replaced with intense pleasure, her shriek turning into a moan midway through. The dog was rather impressed with the cub as well, surprised at how much of his length he was able to stuff into the tiny girl, her tantalising tightness inviting him deeper and deeper until he suddenly noticed being sheathed all the way up to his knot, only the pulsing bulb still left out of her slit. Wanting to give the warbling canary the full experience, he held back his quick approaching orgasm just long enough to pound at her pussy for a few minutes, stretching her until he felt her lips giving way, letting her swallow up his knot as she spasmed and yelled in a fit of delight, reaching her second orgasm of the day and soaking the bedsheets underneath her butt while the canine's load filled up her depths. 

Gasping and panting, Carly tried her best to handle the knot plugging up her pussy, unable to stay still as the canine member pumped squirt after squirt inside of her, every shot increasing the pressure and the feeling of absolute fullness in her womb. Moaning, she ran her hand over her lower belly, massaging the hard lump pressing against her palm while the husky leaned over her, grunting and continuing to give her a few short thrusts as her walls gripped his cock, clinging to him to milk his balls dry. Lyn smirked at her little sister's euphoric whimpering, softly massaging Carly's shoulders while the girl squirmed around in her lap, 
"He's a pretty great lay, right? But don't you dare get used to this, he's mine, and you'd better get yourself your own boy if you wanna continue this sort of stuff~!" 
The bird put her hand under Tony's chin and lifted his head up, staring him down with a wink just as she finished her decree, making it very clear that it was a warning for both the cub as well as her boyfriend, not wanting him to get too comfortable with bedding the tiny avian. Carly could only nod between her groans and huffs, still in the grips of her orgasm, every tiny shift sending another lighting bolt up her spine as the knot throbbed in her mound, her first day of self discovery having started off with great success.
