“James! Mum and Dad said they will be late home so you’ll have to take me to Karate” Jessica exclaimed as she bounced into the garage where I was pumping iron in my shorts while listening to Cradle of Filth in my gym that Dad built at the end of the garage. I’m there with my best friends Glen and Tim. “Urrrruph!” I belch loudly. Pumping iron always makes me burp. The others respond with hilarious laughter while Jessica crinkles her nose in disgust. “God! James you are just gross. To think that I’m related to you” “Jim” I growled. I hate being called James and she knew it. Jessica is my sister and frankly she gets on my nerves as we have absolutely nothing in common. For a start the age difference is too great, my parents having her several years after me. Always remaining the baby of the family she was the centre of my parent’s attention. Probably that’s why I got into bodybuilding at such a young age as an excuse to stay out as long as I could to avoid the sickly fawning of my parents over the little squirt. Although I am now 21 and at a local sporting college I still have that image of her.

Not that I could truly hate her for Jessica was a cute pretty looking kid and has remained so as she has grown. Small, slim and flat-chested she has a little heart-shaped face framed by shoulder-length blonde hair worn tied up behind her head. With big blue eyes, a short thick nose, high cheekbones and a wide mouth full of perfectly white teeth she remained in my parent’s eyes the perfect sweet and innocent little girl. To me she has turned into an arrogant little snobby madame with an over-inflated superiority complex. All her FBook photos were of her dressed up in elegant ball-gowns with her good looking snob friends at events as if she were an upper-class debutante. In reality she was the daughter of a working-class family living in a semi-detached house down a main road who went to a normal comprehensive school.

“James! Are you listening?” she said with a pout that others found so cute while tapping her left foot in annoyance. “Yeah, Karate class. I heard” “What a joke” I mumbled to Glen and Tim who smiled having heard my opinion on the subject many times. My parents started taking her to Karate when Jessica was very young so their sweet little poppet could learn to defend herself from all the paedophiles that had supposedly appeared in our town like a plague of zombies. At first it made me feel uneasy that little 5 year old brats were being turned into a pint-sized army of rampaging killers with an undeveloped sense of right and wrong and a self-centric view of the world. It was totally irresponsible that people were making money training such terribly young kids in a military fighting art that would turn them into monsters capable of beating up their teachers or older brothers if they got told off for doing something naughty. Luckily the classes didn’t seem to change her in the slightest and I relaxed thinking that it wouldn’t last because she was a real girlie girl who preferred playing with dolls to doing something athletic. I just focused on bodybuilding and getting frigging massive. To be honest I never paid any more interest dismissing it as pure baloney for kids.

Now Jessica was a teenager, still cute and an arrogant little shrimp. I heard Glen mumble something about “a nice bit of posh totty” and shot him a warning glance. Her insufferable imperious snooty attitude got on my nerves. She had my parents wrapped around her little finger so that they brought their little poppet all the top designer gear. This she wore with her stubby little nose stuck in the air and giving people an arrogant look out of the corners of her eyes without turning her head. “Phoar Karate babe totty I’d like to put a smile on that stuck-up face” I heard Tim reply and shot him a warning too. Wearing her gi with her feet bare, I had to admit that it stirred up strange feelings. The way that simple white cotton wrap-around jacket and trousers moulded itself snugly to her small slender body, with her cute face could be kind of appealing to other guys.

“W ... when did you become a black belt” I gasped in astonishment at the black strip tied around her around her tiny waist. She pulled a ‘dumb-o’ face. “Uh duh! like ages ago knuckle-head” she stated sarcastically. “I’m third Dan now” she said pointing to the three gold stripes on the belt. “Shows how much interest you take in your sister’s hobby” she added with mock exasperation. I didn’t really know what third Dan meant. To me she was just my little sister, yet the sight of her in that uniform with a black belt made me slightly nervous of my own sister which was ridiculous. “My hands are registered lethal weapons so you better do as I say” she stated with a cocky overconfidence that made me feel momentarily intimated. The thought that my cute little sister was a certified fighting machine was laughable and her superior attitude was really getting my hackles up. Probably due to the vast age difference, there was hardly any sibling love between us. Apart from the occasional exchange of heated words, we didn’t really fight, we just didn’t really get on especially as I really hated her unjustified stuck-up snobby attitude. “Tough, you’ll have to walk. If you’re as tough as you think you are you shouldn’t have to worry about paedophiles. Just stay out of the cars of strange men” I snapped. “But Mum said...” she began to protest. “Mum’s not here now so scram I’ve gotta prep for a contest” I said forcefully.

“You’re just a stupid juicer, James” I spun around angrily. Her pretty little face was all moody and sulky. “You know it’s wrong to use steroids. That’s cheating” “Shut up Jessica” I hissed. “Maybe I should tell Mister Russell” she said in a childish sing-song taunt. Russell was the head at the college. “Shut up Jessica before I shut you up myself” “Yeah you and whose army?” she sneered. “You remember what happened to Bobby Priest when he tried to pick a fight with his younger sister?” [BOBP#1] she asked. How could any boy forget that humiliating spectacle of the attractive blonde gymnast totally destroying her older brother? He let down all manhood in letting himself get thrashed by a mere girl and a younger one at that! “He’s a wimp, besides she’s a gymnast” I reminded her. “Yeah and I’m a Karate 3rd Dan. I could seriously hurt you even kill you” She stated confidently. I suppressed the unease at being threatened by a cute little girl a fraction of my size wearing a gi with a black belt. “Baloney! You better start walking or you’ll be late” I growled.

Swish! Swish! The sound of cotton moving swiftly against cotton as Jessica’s arms adopted a fighting stance with one fist stretched in front and the other by her chest. “I’m warning you James I can really hurt you. So you better tow the line!”. The sight of such a cute girl trying to look tough was laughable, and so I did. With a look of barely suppressed anger she stomped over to a stack of bricks that Dad had put in the corner, left over from some garden project. “Imagine this is your body” she stated in an arrogant tone crouching with her legs wide over a stack 4 bricks high standing on the garage floor. The sweet little blonde in the gi then straightened her right hand open-palmed like a knife and held it poised edgewise over the bricks and concentrated. “Don’t be silly Jessica, you’ll break your hand” I said with concern. “HAI!” she suddenly shouted so uncharacteristically loud that it made me jump and shockingly my groin lurched too. WHUMP! The edge of her hand was a blur as it fell like an axe slicing cleanly through the top brick and driving a big crack like a bow-wave all the way through the 3 bricks below. Jeez! I gulped as my mouth dried up, numb with astonishment.

Standing up quickly with a hard-looking face full of concentration, she span around fast, her right leg rising high at the knee then snapping straight. “HAI!” again her sharp shout made me jump and once again my groin lurched too. A white streak flashed higher than her head towards a wooden cabinet, an old unit that Dad was going to throw away. BLAM! A loud sound of splintering as her dainty foot smashed solid oak to matchwood in the blink of an eye. “Jeez! What a kick-ass little babe!” Glen exclaimed. I was completely stunned by what I had just witnessed that I didn’t even think to give him a warning stare. The demonstration of her unexpected power combined with her flexibility as her leg soared high like a midget can-can dancer had my groin twitching in a manner that was disturbing and to be honest embarrassing. “Now get in that car and drive me to class before I do that to your face” the fresh-faced blonde said with a hard sneer then turned her back on me to walk towards the car. She said it with such arrogance and in front of my mates too that it made me see red.

“I don’t take orders from you!” I shouted as I caught up with her and slapped my hand on her shoulder to make her stop. Like a viper her right hand snatched mine and in an instant sharply bent back my fingers then pulled my arm away. “Argh argh!” I yelped in shock. “God you’re a dumb oik, James” Jessica sneered. “Hai!” I jumped at her shout then a split-second later her elbow was hurtling towards my face. BLAM! “Ouch!” I yelped as her elbow smashed me straight in the mouth mashing my lips against my teeth. I was completely shocked that she had actually hit me! “Argh! Argh!” I yelped again as she bent back my hand at the wrist then forced my arm out past my back. “All those steroids must have turned your brain to mush” she taunted as shards of pain shot up my arm from my wrist. I’ve got to tell you that I’m over 6 foot tall and solid muscle yet was utterly devastated to find a slim girl barely 5 foot tall twisting my thick muscular arm around as if she were bending a straw. “Argh! Argh!” I was shocked that a big strong guy like me was unable to get out my little sister’s hold. Yet every attempt to do was countered by more painful stressing of my arm that I feared would break it. “Oh Jeez man! Stop playing with her Jim. She’s only a girl!” Glen laughed and Tim joined in.

“Arrrgh argghh!” I couldn’t stop yelping as forcing me to stoop she deliberately let me suffer in one hold before moving on to another with a look of sheer domination on her pretty face. “Hai!” her hand swept across her body. WHOP! The edge of her palm chopped the join of my neck and shoulder sending electric bolts of pain coursing through my nervous system causing my body to lock up stiff with my hands shaking. That such a little girl could paralyse me like that made me realise my old fears of an unrestrained army of Karate trained brats was coming true. Laughing Jessica bent back my arm and pressed against the back of my elbow. “Argh arghh!” I cried out as it felt as if she would break my arm. I was horrified to find myself completely helpless at the hands of the little brat. “Look how easy I can control you James” Jessica boasted as she bent back my hand hard painfully forcing me to the ground. She did it slowly so that I was forced to look up at the white clad slim legs, past the slender boyish torso to her young-looking face smirking with arrogance. Oddly enough the sensation of being overwhelmingly dominated by a feminine looking girl was exciting and to my utter horror I felt my dick grow uncontrollably stiff and prayed that no-one noticed. “Look how helpless you are, you big lump” she boasted as she whipped my arm behind me then crouched forcing me face first to the floor. “Oh dear is the big muscular jock being owned by his little sister” Jessica taunted as she forced me flat out on my belly while she knelt behind my head immobilising my arm. THROB! THROB! Oh God No! I was horrified by the beating of my member against the floor, shockingly turned on by being owned by a mere girl. I felt my sister’s hot breath on my ear raising tingles. “Don’t be a stupid juiced-up moron, James” she said “admit that I’ve beaten you then we will get in the car and you will drive me to class”.

“That’s enough love, you’ve had your fun now let Jim go” I was relieved although embarrassed when Glen stepped forward with Tim at his side to intervene. They were both big muscular guys, although not as big as me, yet my sweet elven faced little sister wasn’t intimated in the slightest as they loomed over her. “Oh how tiresome” She said in a bored voice “more juicers who need to be shown whose boss”. Lying on my belly I felt her lean forwards putting weight on my arm. Out of the corner of my eye I saw her turn sideways and draw back her right leg. “Ha! Ha!” her chilling yell broke the silence. A white blur pulsed upwards at an angle right into Glen’s nuts. Two quick-fire kicks one after the other in the beat of a heart. WHUMP! WHUMP! “Arghhhnnnn!” he wailed as her sole stomped his balls. His face turned red and screwed up as he threw back his head howling in agony before creasing over. I felt a shift in the weight pressing down upon my trapped wrist. “YAI!” As quick as lightning her right leg streaked out once more. WHUMP! The sole of her foot hammered the middle of his chest making him grunt as his body jerked. “Yah!” WHAP! Without stopping the same foot kicked up and slammed straight into his face. “Arghh!” he yelled as his body whipped up straight with his hands flying to his face.

The pain subsided as my arm was released. I rolled onto my back just in time to see Jessica slide on her back across the floor towards the feet of a startled Tim. Moving swiftly she folded her knees up over her belly. “HAI!” in an eye-blink both legs shot up together and the soles of her dainty bare feet hammered his groin. WHUMP! “Nnnarghh!” he wailed. To his horror my sister’s legs straightened lifting his body completely off the ground. Openly crying in agony, his feet were lifted clean from the floor by her feet in his balls. A big muscular guy leg-pressed by a slim little girl. Tim toppled off backwards as her legs began to angle away from vertical down towards the ground. I was stunned, in barely a couple of minutes my cute little sister had physically humiliated three big muscular guys, two of who were now groaning loudly with their faces creased in agony, cupping their groins. “How does it feel to be kicked in the balls by feet that can smash bricks, boys?” Jessica chuckled in amusement.

No, no way, I’m not going to stand for it. She’s just a kid, I’m a teen bodybuilding champion. Rubbing my aching arm angrily, I looked up the slender white columns standing before me leading up to the slim torso of the little brat with one fist balled looking down at me smugly. “Don’t even think about it, James” Jessica warned as I pulled myself up from the floor, thankful that my embarrassment had subsided. “Everyone knows that when guys fight a girl, the girl always wins”. That was so condescending I felt myself turn red with rage. “You’re going to get it Jessica” I growled “No more of your tricks or kicking guys in the nuts will save you”. I puffed up my body to try and look really big and muscle-packed. Instead of looking intimidated Jessica gave a coy smile then picked up an empty glass wine bottle off the floor waiting to be taken for recycling. It was one of those thick green Champagne bottles. Puzzled I watched as my little sister sat on a stool and placed the bottle between her bare feet. “Can you do this, boys?” she said straightening her legs with the bottle clamped between her soles. For a few moments there was puzzled silence as the little blonde concentrated on the thick-walled bottle with a scowl of concentration and gritting her teeth. I had no idea what she was playing at and watched in amusement as a slight tremor began in her foot until suddendly. CRACK! the bottle just shattered into loads of pieces. Without a whimper Jessica just stood up with no concern for the shards of glass she trod in. “The soles of my feet are thick with layers of corn” she explained “So I wouldn’t feel a thing if I kicked in your faces”. I glared at her. “Don’t mess with me, James. Karate girls don’t hold back” she warned trying to intimidate me. Jessica raised her hands open-palmed like she intended to deliver a Karate chop. “These hands could knock you out cold in an instant” she warned. I had to admit that she looked pretty intimidating with her cocky confident manner.
