It was always hard for Kari on Tai's practice days. As the next stage of schooling approached, she found more and more of her time was occupied with tests and entrance exam preparation. She didn't really have the freedom of a child any more. Kari did still make an effort to come, she knew that this mattered a lot to her brother, so whenever she could Kari spent the time to watch him play.

Well, that was the excuse anyway, the truth was that Kari always got excited watching her brother play. His strong yet slim body moving around the field with such grace and precision made her shudder. She wanted him to touch her, wanted to feel those strong muscles against her chest, she'd seen him out of the shower enough to know he was pretty big where it counted as well. While Kari was still relatively inexperienced regarding actual boys, she had experimented a bit with herself.

From her seat she bounced up and down trying to keep her excitement to the level of an enthusiastic sibling, it was just a practice game, after all, shirts and skins and Tai unfortunately for Kari's libido, was on the skins team. It was quite challenging to try and avoid thinking dirty thoughts as her mind shifted to her sensual desires. It was a forbidden love for her brother she knew would never be granted.

It was too much for her, the sight of her brother's bare chest drenched in exertion, his muscles gleaming and his face full of a competitive edge was driving her crazy. She swallowed hard standing up abruptly and started making her way off the stand.

She was glad that TK had cancelled on her today. She didn't want anyone to miss her, considering what she was about to do. Wordlessly she slid behind the bleachers, the slats of light and noise making her think of the sweaty boys taking the ball around of her muscular big brother.

Kari's entire body was covered in sweat. Glistening slightly in the early evening as she found her private spot beneath the bleachers. Her exhibitionist streak was growing every now and again, and Kari felt a shiver as she pulled out her secret bag of toys cunningly hidden beneath one of the support pillars, a tiny Hello Kitty backpack that contained every illicit purchase Kari had ever made.

Kari rummaged through the bag, hands caressing many smooth and angular surfaces before finally settling on her newest acquisition. A perfect plastic penis, complete with remote. Kari pressed the button and felt the small toy buzzing between her fingers, perfect.

Kari opened the button on her pants, she wore skirts so often these days it was kind of nice to go back to a classic pair of shorts that showed off her long, perfect legs and her tight and pleasing bubble butt to anyone who would notice. She groaned slightly placing the smooth plastic against her mound as she twitched emphatically. This was so naughty if she ever got caught… well, she'd probably die of embarrassment and arousal.

She took a long but tensed breath as she slipped her hand and the shaft of the vibrator deeper inside herself. A small part of her wanted to get caught, to show everyone just how ridiculous the image of innocence people gave her really was. Kari definitely didn't do more than flirt usually, but a part of her did actually want to walk on the wild side. It was something that Gatomon exemplified better than she did. That girl got around.

Her other hand grasped upwards revealing her perfectly pink protruding nips to anyone lucky enough to view her as she played with herself in public. Her treasure was glistening as she felt the smooth plastic rub against her lewd love button.

Kari moaned imagining a situation where her brother was the one who caught her. He places hands on her sides and then put her over his knee with her bum sticking in the air as his hand swatted her rear.

"mmmm punish me, please... big brother," she gasped sliding the smooth ovoid shape inside her panties before tapping the button.

The shaft burst to life, a low humming as it kissed her clit and made her entire body writhe in response, she loved the sensation as she rubbed against the support lustfully, without any kind of shame

Kari groaned and felt her hand reach inside her pants, she knew she shouldn't do this, that it was wrong to fantasise about her brother, imagine his body against hers pressed hard as they shared a forbidden kiss but she couldn't help herself. Kari had always had a crush on her brother. Her rise to womanhood had merely meant that it had gone from idle admiration into full-blown sexual fantasy. It was part of the reason why she still teased Davis after all these years, he'd modelled himself so effectively after her brother, but it was hard not to see the appeal. But you couldn't beat the original.

Already merely the thought of her brother in a sexual light had gotten her wet and Kari could feel her smooth sex heat up as she exposed it to the early evening air.

She fumbled for her bag pulling out a large ovoid vibrator from the collection that sat cunningly hidden at the bottom. Kari actually shuddered a bit, part of her wondering how it would be if she ever got caught, would she get disappointment? anger? Would they watch her play with herself? Lose her seemingly innocent look?

It made her shudder and moan all the more. She imagined what her brother would do if he ever found the large orange dildo that currently sat at the bottom of the drawer. Nobody knew that Kari was secretly like this, and for now that was a secret she kept very well. She stretched her legs wide and began to explore her depths with the vibrating device eagerly.

Kari sighed and began to move harder along her own body, struggling to keep quiet. She felt her lips parting a hair's breadth, her warm breath shimmering as she continued to massage her love button. The Chosen of Light felt her body buck back and forth quivering up and down as she dreamed of her brother's strong hands and impressive physique. The sultry sister spread her legs wide toes curling in her sneakers riding the wave of pleasure as she tried to simulate his paddle on her rear.

"That's it, big brother, I'm a bad girl! Punish me! Brother," she groaned relishing in the sensations of her masturbation, her pleasure building as her stomach contracted small knots in her body as felt her eyes waver back and forth.

She could fill the orgasm building ready, the desperate desire to let her depraved fantasy take flight. One hand was still playing with her perfectly pert breasts while the other buzzed against her body. She grit her teeth swallowing air as the juices exploded inside her panties.

"So you want me to punish you huh?" Asked the familiar voice of Taichi Kamiya, but different somehow, like somehow the Tai of reality and the deepest incestuous fantasies had collided.

Kari practically froze, two fingers pressed inside herself with her vibrator buried deep and still buzzing slightly. Kari let her head move slowly, panning like a camera to the silhouette of her fraternal sibling. Kari swallowed hard, her liquid brown orbs staring into his with a combination of fear and arousal.

Kari felt her lip tremble as Tai watched her, her face burning from the shame. He had to of heard her, had to see her orgasm moaning his name… He was going to hate her.

Tai's eyes wandered across his sister's body her open shorts, her sweat-stained body, the dark patch that stained the crotch of her shorts and revealed the shame of her incestuous fantasies. Initially, Kari was sure he was going to shout at her, his eyes glinting in surprise, his jaw dropping in extreme shock before the spectacle.

Tai's eyes seemed to be different, the apparent shock and surprise she had expected were present naturally, yet as she lay there quivering in her own juices staring into his eyes. She noticed something different, something unexpected, so unexpected she almost cried out. It was frightening yet exciting at the same time yet Kari could see her brother's arousal.

Kari heard him swallow hard as if deciding on something. She sat there trembling as he slowly and confidently walked towards her a cocky grin on his face as she felt her breath become ragged. She was scared of him, afraid of this confident, swaggering bravado that he had turned upon her for the first time.

Tai picked up her bag of sex aids, inspecting the contents as Kari lay there frozen one hand still cupped around her breast while the other hastily removed itself from her damp crotch like she'd been stung.

Tai for his part had not said a single word since his opening line, preferring instead to let Kari's stew in her own juices. The bold brother pulled out a large orange dildo, inspecting its smooth composition before holding it out for Kari to see

"Why has this one got "Niisan" scratched into it?" he asked grinning at her discomfort.

"And here I thought you were a good little sister," he chided, slipping the oversized false penis back inside the bag before finding something more interesting. He leaned down kneeling before her before reaching in and grasping the damp plastic oval she had been playing with while she fantasised.

"And what is this naughty thing?" He asked rhetorically holding up the slick slime covered vibrator to Kari's eyes and grinning gleefully as he gave it a long, languid lick.

Kari squeezed her eyes shut for a moment, pinching herself as if to prove this wasn't a dream. Nope Tai was still standing over her savouring the flavour of her juices off her new sex toy.

"I never expected my sweet and innocent Kari to own something like this," he teased. "Whatever would happen if TK learned about this?"

"I think I have an idea of how I'm going to punish such a naughty girl," said the boastful brother with a knowing smirk. Tai experimentally licked the soaked sex toy, savouring the taste of his precious little sister's juices. With a sly smile he placed a single finger on Kari's lips probing them with her own juices.

Kari shuddered, it was like every fantasy she'd ever had about her brother, that devil may care attitude shining through despite the perverse nature of his actions. She let out a soft moan as she felt Tai place the tremendous toy in her outstretched palm and then wordlessly handed her a second. This one was longer and more traditional, shaped like a small phallus.

"Well, what are you waiting for? Let's lose those shorts," He asked his voice never straying from its authoritative tones, "I want to put these inside you," he remarked pointing to each device in turn.

Kari burned with embarrassment as she obediently did as she was told. Her hairless sex now entirely on display as her shorts and panties slid down to her ankles. Tai made sure to lean in close, his breath briefly tickling her raw skin before he started to push the un-lubricated vibrator slowly inside her dripping snatch. With agonisingly slow movements Kari felt his clumsy fingers shift the device upwards. Feeling her lower lips wrap around the offending device, she moaned.

Then she felt his hand on her body, grasping the other device between thumb and forefinger Tai began to work the juice-laden shaft against her pucker slowly. Kari's eyes went wide her jaw dropping as she felt her brother's fingers slowly open her anus. The slow procession of the juice-laden joy buzzer into her rectum making her moan loudly. Tai grinned all the more making Kari melt slightly as she felt him push the offending object to a satisfactory depth. Kari felt so full, and yet now she had a horrible ominous knowledge of what was to come.

Her brother had shoved two vibrators inside her, and from the look on his face, it wasn't just the satisfaction of being filled by her toys that she was going to have to endure. Kari couldn't wait.

He pulled back, wiping his fingers on his shorts before motioning for Kari to follow him.

"On your feet Slut!" Said Tai confidently adjusting his shoulders as he watched his little sister struggled to pull her panties back over her slightly distorted mound.

Kari struggled to her feet biting her lip nervously at the strange discomfort she felt. She'd never walked around with something inside her before, and it made her waddle awkwardly. Tai simply kept grinning that Cheshire cat grin, placing a hand under his sister's chin as he examined her. His hands caressing her body slightly as he explored her semi-nude form. Kari could feel his grabbing grasp reached up and touched her nipples making Kari moan lewdly.

"Such a beautiful body, I always thought it was wasted on Davis and TK, "remarked Tai in a low possessive voice, "well, neither of them got to see this, your mine now," he added his voice dripping with greedy delight.

Kari couldn't help but moan all the louder, her mind wholly consumed with even more dark and tempting fantasies. She couldn't believe how perverted her brother was and she couldn't be happier with the discovery. Kari moaned submissively. She could feel her brother's hands squeeze and abuse her so beautifully, the hand easing the toy in and out of her. She panted heavily, her tongue visible as Tai ended his petting session with a sudden and expressive pinch. This was torture!

With an effortless action, Tai unclipped Kari's bra and began to stuff the garment into his pocket deftly. Kari swallowed hard aware of how her nipples stuck out like little mountains against her softball sized mounds. It was obvious now to anyone that looked at her that she wasn't wearing underwear up there.

"Let's go home little sister," remarked Tai in a voice that made it clear she had no choice in the matter holding out his arm in what seemed like a mockery.

Kari was about to protest when her eyes met his and her argument died on her lips. That feeling of raw power overwhelming her.

Kari nodded taking his hand as they walked together. Tai, still sweaty from his exertions and dressed in his soccer kit, led his little sister to the train station. It was hard for Kari to keep up. Every move she made pumped the foreign objects inside her all the harder. She gritted her teeth, glad that at least the devices had not been turned on as she half walked half waddled beside her brother.

Tai was humming something, a jaunty tune about butterflies or something she thought. He walked alongside his sister, occasionally glancing at her stuffed snatch currently secreted into tight shorts. Tai looked so smug as if his plan had gone off fluidly even though this was pure chance.

With a self-satisfied smirk they crammed into the train Tai making sure to push his little sister against the window, it was subtle but once again reminded her of the power dynamic the now shared. The heart thumped hard as she realised how much she loved the idea of her brother owning her, how she longed to feel him take every aspect of her. Even now as he took on a position of seeming to protect her, she could feel his hands squeezing and caressing her rear.

He leaned in until she could feel his slightly tacky body against hers, blowing against her ear as he did so.

"Now then, let's begin a suitable punishment for such a naughty little girl," he scolded.

Kari felt the buzz before she heard it as he slowly began to activate the twin pleasure buds inside her, One thumb languidly easing on and off the dial of intensity as he slowly started to press his tented shorts against his sister's plush posterior.

Kari blushed, aware of the mammoth manhood that was hot dogging her and feeling her rectum swallow the terrible toy inside her. She gasped, desperately trying to suppress her own moaning. Tai placed a hand across her mouth pushing her body against the train window. Kari felt a flash of surprise as Tai began to ease up her shirt slowly.

She hissed as she felt his hands on her belly fingers moving to caress upwards. Each time his hands reached towards her breasts, she could sense the remote for the vibrators being turned up incrementally.

Tai grunted slightly pushing his hardness against his sister's rear as he continued to torment her. Every time she tried to make a sound he would stop, she couldn't bear that to make him stop feeding her never-ending need for his touch.

Kari pulled up her hand, biting down hard on her own fist to suppress her moans as Tai began to expertly manipulate her breasts, pushing her against the cold glass of the window. His hands moved downwards, taking the time to slowly but surely massage her mound through her shorts, every time his dexterous digits came near her muff Tai made sure to click the controller and give her a burst of pleasure.

Kari bit down so hard she was scared she would draw blood. She desperately bucked herself back and forth with how tightly they were packed inside and out; she wasn't sure if anyone could see them.

Kari Kamiya stared at her own reflection, her eyes wild with pleasure, her mind swimming in endorphins as her brother continued his perverted play, taking every opportunity to push her just a little bit further.

Kari felt her body begin to twitch, the familiar warmth of an orgasm magnified thousandfold by the danger of the situation. She had practically swallowed her fist, groaning as she felt her body lose control. She leaned hard against the window breathing heavily as Tai finally relented, deftly catching her, preventing her from falling.

"Please big brother," begged seductive sister meekly "no more…" she whimpered about to beg him to fuck her right there in public.

And then the train announced their stop. Kari let out a sigh of disappointment and then the realisation that her brother had been playing with her body in public finally set in. Kari flushed heavily, terrified someone noticed the explosive end, but no one turned around, no one seemed to see her pressed against the window, like some kind of wanton wench. Still, her heart froze as she did a quick look around.

Tai grinned knowingly before helping Kari to her wobbly feet.

Kari could feel the vibrator still buzzing within her now soaking insides as the doors opened and Tai confidently led her home.

The orgasm had washed out and she could barely walk, feeling the aftershocks of her explosive release quake though her, she was still pleasure drunk. Her feet seemed clumsy as she practically hung from her brother's arm, he was a support, but at the same time, she knew that this helping hand would come at a cost, a cost that would probably include her virginity.

The sinful siblings crossed the threshold of the Kamiya's apartment. Kari almost immediately fell over as Tai grasped her by the waist as he lifted her over his head. Kari moaned finally uninhibited as her brother lifted her off her feet and slung her over his shoulder like a sack of sodden laundry. Meaty hands reached up and slapped her rear playfully as he carried her into the living room.

Kari squealed in surprise, his sudden show of strength making her melt almost as much as his earlier show of dominance. She gasped in unexpected joy as she felt him pull her into position. Tai flopped onto the couch. Kari felt her body move around as her brother effectively repositioned her, she could feel his erection against her belly as his hands moved to play with her pert posterior again.

"Let's get to your punishment, my naughty little Slut" growled Tai authoritatively as he began to slide her shorts off her rear revealing her sweat and juice soaked panties which he quickly slipped down her legs.

Kari felt the toys inside her buzz again as Tai began to lightly play with her body again taking care to massage her amazing ass. Kari could feel the cold air of the early evening against her sex as Tai began to lightly stroke up and down her behind.

He placed a finger inside her, neatly feeling for and pulling out his toy before settling for a quick yet satisfying whack against her supple flesh.

Kari felt the sting and cried out in surprise and pain, her brother was spanking her, treating her like a naughty child, yet every time that hand moved in close and rang against her rear. Kari could feel the pleasure mounting in time with each perfect stroke. Despite what had been done to her with the toys earlier Kari felt more aroused than ever, crying out in surprise and pain with each a regular strike. She could feel her butt cheeks burning. Her face shone with a combination of shame and arousal. Every now and again Tai would dig a finger inside her treasure between strokes as if he was testing her readiness.

She felt his hand move back and strike her, again and again, each stroke being both broad and reliable as he got into a rhythm.

She could feel his erection against her belly, his hardness was so achingly close as he continued to punish her for her bad behaviour.

Kari felt her body tense again the stinging on her rear combining with her own stimulation. She was loving how her brother continued to vigorously paddle her backside playfully even though it was clear he wanted to take her.

After a while Tai seemed to stop, taking a moment to savour his sister's tasty nectar before finally moving her away.

Kari felt her legs hit the floor and found herself kneeling before her senior sibling, her shorts around her ankles, her body ready for his pleasure. Tai effortlessly pulled on the waistband of his shorts revealing a respectable 8 inches of erection for her to play with.

"Suck!" He commanded emphatically grabbing the back of her head to make the point crystal-clear.

Kari nodded her eyes slightly teary as she opened her lips and began to slowly and surely take his mushroom head down her throat. She'd never done anything like this before, and Tai occasionally winced as her teeth grazed along the shaft before he lost patience and began to facefuck his submissive sister.

Kari nearly gagged as she felt his entire shaft shoved down her throat suddenly, Tai's hands now firmly placed around the back of her head as he used her for his pleasure. She tried to breathe through her nose, her eyes wide and teary as Tai forced himself on her continuously. Kari felt the vibrator inside her ass continue to buzz again set to maximum as Tai force-fed his cock to her. She spasmed, again and again, pleasure overwhelming her mind as she struggled to breathe, completely lost in pleasuring him.

He caressed her cheek between thrusts, encouraging her with the dirtiest words.

"You love this don't you little Slut, love being used like this, you've always been tempting me, every time you came out of the shower in just a towel you wanted this, wanted me to punish you. Well, now you better take it like a big girl because I'm just getting started."

Another orgasm buzzed through Kari's body as she felt her brother's cock twitch in her mouth. He pulled back just as the spray of semen began to push out of it spattering white goo all over his little sister's face and body with a mighty roar of pure unadulterated lust.

Kari coughed a little bit, a small amount of semen slipping down her throat. The salty taste of her brother dominating her mouth as she stared up at him in awe.

Tai happily placed a hand on his sister's shoulder gripping her tightly.

He pulled her up and with very little hesitation eagerly nibbled on her neck.

Kari knew what was coming next as he stood up straight and gave her body one last delightfully deviant inspection.

She was still wearing a little clothing and Tai clearly wanted her naked.

His hands moved up and down her body, fingers caressing her sides. Squeezing the slight paunch on either side of her flat stomach. Tai seemed to be examining everything about her, examining her filthy mind as well as her seemingly unspoiled body.

"I wonder how you'll look with a tattoo right here" he remarked playfully stroking the small of her back. "Something tasteful, like a tramp stamp," he added making a distinctive effort as he pulled her shirt over her head inspecting her tiny tips critically before taking a moment to nibble on them.

"Or maybe we'll get these pierced? We can put some rings in here for me to play with," he mused flicking her nipples licking each one in turn before kissing up between her modest cleavage.

"You can do whatever you like to me brother, I'll do anything for you just please Fuck me already!" begged Kari.

Tai smiled placing a finger on her lips as he moved in to take his kiss. Kari felt her entire body explode as he pulled her in and rubbed her against him. The giddy girl could feel his erection still sticky with her saliva as it rubbed against her thigh. She knew what was going to happen next. It happened in her fantasy so many times after all.

Kari couldn't have resisted if she'd wanted to as Tai pushed her onto the couch. Squeezing her firm rear in that powerful way, Kari could feel the sting of her behind from the previous abuse before she felt her darkest desire.

He pressed her face into the cushions of the couch barely allowing her enough space to breathe as she felt something warm and sticky slide across her open sex.

"Please take me, make me yours" purred Kari slowly but surely shaking her rear, she felt his head against her mound and moaned in forbidden pleasure as Tai began to ease himself inside her. This was just like her fantasy, except the real thing, was now stretching her wide

"I wonder what Davis would think if he could see you now, would he be disgusted by you? Would he be aroused watching you bouncing on your brother?" Asked Tai, getting into the mood even more and taking moments to make ringing strikes along her bubbling butt flesh between deep thrusts of incestuous delight.

Kari shut her eyes imagining the scene TK and Davis both watching her as she let Tai turn her into his plaything. She couldn't help herself the image made her orgasm again. Her tongue rolled out of her mouth briefly as she drooled into the couch cushions. Tai took full advantage of the moment of her spike to plunge even deeper, his stamina must be near superhuman considering how she was battling to keep up.

Tai took the time to grip her arms holding her in the position of supplication as he ruthlessly pounded her pussy. Years of pent-up sexual energy between the sinful siblings exploded in passionate movements.

"You feel amazing little sister," said Tai as he gripped her wrists, "best Fuck I've ever had, I guess what they say about siblings being made for each other is true," he grunted never letting up in his assault on her deepest places.

Kari didn't answer, her own mind lost in lustful abandon

Her arms flopped uselessly to her sides. Her entire body now nothing more than a warm hole for her brother to slide into. She surrendered to him completely, whimpering in pleasure as he continued to say the most degrading things.

Maybe I'll introduce you to my side girl, I know that she always had a thing for you, would you like that little Slut? Drinking my seed out of another woman? Debasing yourself for my little Meimei?"

Kari's eyes squeezed even more tightly shut, each lurid fantasy filling her with longing.

Licking out Mei while her brother pounded into her from behind? TK Davis and her brother all showering her in a naughty seed. Her brother showing her off in the digital world wearing nothing but a collar. The idea of a collar made her whine, the simple appeal of him owning her made her whole body explode in pleasure.

They went at it for quite a while Tai taking long full strokes enjoying his pleasure as he thudded into her from behind.

Tai grunted hard pushing as deep as he could as his cock began to twitch inside Kari's fertile fount. It was entirely determined to deliver his boiling bounty of brotherly love directly where it would make the most impact.

"Big Brother!" Kari moaned emphatically.

She shivered as what felt like buckets and buckets of semen shot inside her secret place. He pushed her face deeper into the couch, seeming to enjoy her dominated position.

Finally, when he was finished, she felt his hands let go of her arms, making her slide off his cock with an audible squelch.

"My little sister is such a huge Slut! Luckily you're my Slut now!" Growled the dominant brother. He gave her still stinging ass another firm and authoritative slap to prove his point.

Kari didn't say anything, her tongue lolling out of the side of her mouth as she lay there a dripping and drooling mess. Tai's fresh creampie slowly dripping out of her cunt. She just lost her virginity, was treated like a slave and loved every second of it.

She felt Tai squeeze hard on her rear and moaned in happy resignation. She belonged to him now, and that was precisely what she wanted.
