Chapter 3 - Ginny's Destruction / Billy's Muscle Meeting

The young teenaged girl stood in the middle of the basement. In front of her stood racks and racks of weights, and a large, wrought iron plates stack machine. It all belonged to her father, who in his prime was a silver medalist Olympic weightlifter. He no longer used it after his injury, but it sat in the basement of the family house, unused, until she had finally gotten permission from her reluctant father to use it. Her body, over the period of months, had become curvy, fuller, and more solid, far from the skinny beanpole she had been when she began to lift vigorously. She still carried a bit of babyfat, but just a bit - overall, she looked athletic and hard, especially for a girl of only nineteen years.
Hillary grimaced as she hefted the heavy weight. She had nearly half of the stack on for a set of curls, but it wasn't really even fazing her. Energy filled her body as she lifted the weight again and again, loving and needing the burn in her surprisingly developed biceps.
Hillary had always secretly admired the female bodybuilders she had seen as a child on the covers of 'muscle' magazines. She even had a large collection of them in her room, hidden, and she would often look at them at night and wonder what it would feel like to be that strong, that big, that mind-blowingly muscular. Sometimes she felt strange and freakish for worshipping these antithesises to femininity, these huge, muscular, ultra-strong and veiny superwomen, but there was something about the sight of the hard, oiled, pumped female bodybuilders, perfectly tanned, their breasts full and voluptuous even with their bodies in obvious contest, depleted and striated shape; The way their stomachs were lumpy with a wall of abdominal muscle, the way their lower back, big and thick, sloped into the swell of their glutes, the large corded muscles evident against the fabric of their tight, small bikini bottoms. Hillary wanted those bodies, to touch, to feel, and most of all, for herself to posess and have others look at her in that way.
She started lifted weights at an extremely young age, becoming an exceptional gymnast. Honestly though, Hillary thought, she could care less about gymnastics. In truth, gymnastics just gave her a way to use the body she was building, an excuse to begin to form the bases of the muscles she wanted to one day posess. She lifted as heavily as possible, quickly thickening her growing body into an impressive physique for such a young athlete - but still, it wasn't enough for her, so she kept pushing and pushing herself to the edge of physical exhaustion with each workout. Often she would have to go directly to bed after her grueling, hours-long workouts - but Hillary never missed the opportunity to dress in her skimpiest bikinis, door securely locked, and practice posing in her full-length mirror, imagining her impressive physique multiplied, over and over again, until she was satisfied. Big, thick, strong biceps were her dream - she wanted to be huge, as big as the girls in the Olympia, bigger than any woman in the world!
She had to constantly hide her enthusiasm when lifting with her friend on the team, Ginny, an athletic, buxom redhead who turned heads at the high school, despite the fact that she was a young eighteen and a junior, which often engendered ridicule. To put it nicely, she wasn't very quick - to counter, her model looks and the fact that she was already built like the fitness competitors Hillary sneered at while flipping the pages of her hidden Women's Physique World magazines, curvy yet sinewy, and cut. Her 'fitness' look was more in line with social norms than the swollen, beefy and striated bodybuilding women that Hillary admired.
Ginny regularly wore sleeveless blouses and cutoff shirts to show off her popping shoulder muscles, lean, cut tris and flat, solid stomach. She told Hillary she didn't want to lift weights too much, she didn't want to ruin her 'beach girl' body. Hillary agreed with her vocally, but inside she knew the truth, and looked down on Ginny for her views on girls and muscle.

Hillary continued to curl the stack, her biceps flaming and tingling oddly. "Jesus, that powder I took really must have kicked in!" she squeaked, as she completed another efortless rep with the 50 pound setup. She was amazed - even with both arms and her years of strength training, she still could only really manage 35 pounds legitimately. But this weight felt like a feather, like no stress. She looked down at her arms, to make sure of the weight, and her jaw dropped.
Her biceps looked just like the girls in the magazines. Erupting from her elbow was a thick, massive biceps head. The heavy weight stack dropped with a clang as she gasped, touching the steely biceps heads in amazement. They were real, and hers - heavy and thick in her small hands, Hillary felt their stone hardness with delight. She flexed them, slowly, her hands cupping the erupting mountains of power.
"Holy shit!" she exclaimed, a huge smile on her face, as she thought about what she had done differently today - her day flashed by like lightning in her head, and came to rest on the jar of weight gainer she had bought at the drug store after all the other girls had slipped out. She had simply put the vitamin supplement she had in her hand the whole time to the side, sliding the muscle powder into her right hand ....
Hillary squeaked and ran to find the jar. Panting, and nervous, she unscrewed the lid, trying to think of the best overall body workout she could possibly perform. As the lid popped off, Hillary thought of excruciating, endless reps of muscle building, sweat inducing workouts as she began to cram the powder into her mouth by the handfull. After seeing the transformation of her biceps from supple, slightly thick arms into ropy, muscle bulging ridiculousness by the simple set of curls, Hillary was in muscle lust. As she choked down dry powder, she thought of the way her thighs would swell, rippling with muscle and tendon, as she performed a full body flex. In her mind she was gigantic, sweat slicked, bigger than any Mr. Olympia imaginable. Her cut, six pack abs rose to huge breasts, jutting out perfectly straight on bedrocks of huge muscles, barely containable by her tiny bikini .....

Hillary emptied the jar into her mouth, licking the remnants of the powder from her face as she ran to the gym equipment. She laid down and the bench, and began to violently bench press the loaded bar. At only 100 pounds, she soon found it to be insignificant. Her young chest rumbled, billowing in her t-shirt as the pecs grew instantaneously to manage the weight. Her entire upper body swelled, stretching the shirt like a second skin, as she loaded another 80 pounds on it, the plates feeling very light in her strong hands. The extra effort made her forearms swell, beginning to like like Popeye's.
As she laid down to heft the gigantic weight, she noticed the effects were compounded. Her upper body was huge, large thick lats competing with swollen, rigid pec muscles for room. Her waist was tiny, and yet to have been reinforced with hard muscle. The effect made her look like a ciomic book supergirl, outlandishly muscled and misproportioned. "Oh well," she whispered, "I can do situps in a bit," as she began to pump the bending bar in a frenzy, her entire upper body trembling and swelling with growth.
Seams began to pop in her tshirt, unable to accomadate the unnatural spurts of muscular redoubling Hillary was forcing her body into. At rep 25 with the high poundage, Hillary locked the bar and rose. Her chest was gigantic. Her small breasts were eclipsed by huge mounds of squared muscles. The swells of her pecs rumbled as she flexed her chest slightly, and the tshirt brushed her chin. Hillary giggled excitedly as she looked down the now stretched and misformed shirt, to the sleeves that encased her unbelievably thick arms. Veins pulsed along her tanned skin as she flexed her massive guns. The shirt's tight sleeves looked like sausage skins, stuffed to the snapping point. As Hillary finished her flex, they did - her sleeves exploded with an audible "POP!" Huge swells of muscle erupted, cut as diamionds, from her arms. Hillary oohed and ahhed, eyes locked on her tremendous arms. She couldn't draw her eyes away from the sight of her arms, filled with powerful, surging muscles. She filled her hands with her on stony arms, still not quite believeing their amazing transformation. Hillary vigorously worked out for almost two hours, hefting ridiculous poundages with ease as she built up every muscle in her body - by the end she was sore all over as her body, now filled in and pumped with tremendous musculature, finished its spurt of amazing growth.

She was gigantic, thick with slabs of muscle, but not really defined - Hillary didn't care - the size of her muscles was more than a dream for her, and she admired herself in the mirror, tensing barrel-like thighs that pulled her biker shorts upward abruptly, the immense flexion causing a slight tear near the bottom. Giggling, Hillary turned sideways and flexed her butt. Her cheeks rippled and erupted with size, and the bike shorts gave in - with a loud rip they fell from her, and she went instinctively to cover herself, as she had on her white lace thong panties - she only ever felt comfortable working out in thongs. Her butt was solid muscle, and a little delineated - it made the tiny string that disappeared in between the heart shaped swells like even tinier than it was.
"All right Miss Thompson," came from upstairs, and footsteps.
"Shit!" Hillary whispered to herself, "Ginny's here?" She scrambled, her eyes wide, not knowing how she was going to explain her new mass and unbelievable body to her friend. Not to mention her clothes. Quickly, she ran to the corner of the room, hiding partially behind the stack machine, peeking her face around the corner of it. She heard the door to thr basement open, and light footsteps down the stairwell.
"Hillary?" came Ginny's sweet voice, and Hillary saw her red hair, gleaming beautifully in a tight set of pigtails that the boys at school would've simply loved. Her sweatsuit looked like it had shrunk in the last week or so, the powder blue fabric stretching at the seams under her suddenly odd-looking feminine curves.
"Uhhh, Hi, Ginny," Hillary managed, and noticed her massive shoulder in plain view. She quickly ducked further behind the stack, and bit her lip nervously.
"What are you doing back there, Hillary? Come out here, I have to tell you about something!" Ginny was obviously very excited, Hillary thought, she's even more bubbly than usual.
"Umm, I'm just adjusting the weights, Ginny, what did you want to tell me?"
"Something's happened to me, Hillary!" Ginny piped, excited. "I have MUSCLES, Hillary!" she squeaked, obviously delighted, and began to peel her skin tight sweatsuit from her waist up. Hillary's eyes popped when she saw the bottom of her young frined's ripped, protruding washboard abdominals, ugly veins covering the bubbles of tanned muscle to snake down into her panties. Each inch of fabric removed revealed more hard, rippling muscles, until Ginny stood in the basement in her tiny, electric blue matching lingerie, the black lace and miniscule satin pieces of cloth rivalling her muscles, giving an unnatural duality to her tremendous body. Her tight pigtails only enhanced the strangeness of her appearance - she was equal parts schoolgirl, Victoria's Secret model, and bursting musclegirl. She was smaller than Hillary by far, but her muscles were striated, cut, and splashed with veins, whereas Hillary's massive bulk was contrarily thicker, skin stretching, and voluminous. Ginny looked fantastic.

Hillary looked in envy at a body that she knew many boys at school would have dreamed of having if they knew how good all the muscle looked on her - Ginny's arms were ripped, with large rounded muscles exploding from the joints of her small frame. Her chest rivaled Hillary's in size, but that was unflexed - long, disgustingly deep striations shifted across the thick pec muscles with Ginny's slightest movement. Her stomach was rock hard, protruding by inches with shelfs of ab muscles. Throbbing veins covered every inch of exposed skin, which was quite a bit in her tiny bra and thong panties.
"And all I did was a few pushups, and look at these muscles!" Ginny bubbled, running her tiny hands along the sides of her iron stomach. She sighed, tilting her head back as her hands reached the cups of her bra. Hillary looked at her with envy and disgust - Ginny didn't even want muscles, but here she was with an amazing, cut physique for only as few pushups? Hillary looked at her own arm, thick and rippling with muscles, but not the cuts and definition of Ginny's huge upper body. And she had been pumping iron for the last hours, sweat pouring down her body as she pounded out reps with unimaginable weights, in a muscle frenzy - she wanted to be big, strong, muscular .... and Ginny, who was always Miss Perfect, came in and effortlessly won even Hillary's admiration for her Amazon teen's body.
Ginny continued to look in awe of her own body as Hillary stepped out from behind the weight set. In comparison to Ginny's lean, striated physique, Hillary was swollen with thick muscles and that still persistent layer of baby fat.
"You have muscles too!" Ginny cried, excited for her young friend. She ran up to Hillary, and started performing freakish-looking muscle poses next to the larger teen. "Show me your guns!" the young redhead giggled, pumping up an impressively diamond cut bicep of her own. Hillary acquiesced, emabarassed, and a thick, rumbling bicep appeared on her arm.
"Jesus, you are huge!" Ginny bubbled, "but it looks like you'll have to hit the treadmills for a little bit," she joked, and patted her rippling, washboard stomach. The sound of her tiny hand smacking solid, thick muscle drove Hillary over the edge. Hillary effortlessly pushed Ginny to the floor, and began loading a barbell with every plate she could find.
Grunting incredibly loudly, loud enough for the entire house to hear, Hillary hefted the amazing poundage to he shoulders with a small cry of both pain and victory. Tortuously, she began to lirft the forboding weight, and tears began to well in her eyes from the intens effort. Her entire body burned as she completed her fifth repetition, and the tears began to stream freely down her face. Still she didn't relent, and her arms had become pumped with blood and swollen, her biceps ballooning alarmingly with each tortuous repetition - She grunted loudly, her mouth open as she panted with the exertion.
"Hillary, please stop it!" Ginny cried, her hands going to her mouth in horror. Hillary ignored her, tears streaming down her face as she continued to press the weight abover her head. The bar was so heavily loaded it bounced as she heaved it, her muscles exploding with growth for every rep. The incredible torture she was putting her body through triggered the mouthfuls of powder into a second stage reaction somehow - Hillary cried out, groaning loudly, as another twenty pounds of muscle coalesced instantly on her tiny frame.
Her muscles bulged crazily, huge and exploding all over her young body. Inch thick purple veins sprang to prominence on her quivering mounds of bicep meat. Ginny began to back away from the hulking teen amazon, as if afraid she might explode. Hillary screamed violently, her body shaking as pounds and pounds of muscles fought on her tiny frame for room. Her arms were now well over twenty inches, and looked ridiculous except for the surrounding mountains of muscle on her neck and back. Cabled veins ran up and down her back, visibly pumping blood to Hillary's unnaturally pumping, huge teen muscles. Hillary threw down the barbell, and threw her arms around herself as her body racked with pain.

"OOOOOooooooh!" Hillary moaned, her head swinging uncontrollably as her body continued to erupt with new size on every inch of her frame. Her legs were tree trunks, forty two inches of quivering, vein covered meat. Her white panties were just barely visible amongst the swells and bulges of her lower body. Her midsection was wide, thick, and sickeningly cut - Hillary was exhibiting a full fourteen pack of cue ball sized, shiny muscles along her stomach. Hillary's skin was audibly stretching to accomodate her girth, her arms finally settling at an amazing and unnatural twenty four inches of power. Ginny dropped to her knees, eyes wide, in front of Hillary's goddesses' physique.
There, in front of her, stood the strongest, most muscular being, man or woman, that Ginny had ever seen or even heard of. She was sickened and intrigued at the same time by Hillary's gratuitously muscled body and razor sharp definition. Her pearly-white skin was stretched translucent along the shelfs and valleys of her astounding musculature. Hillary's eyes were closed, a smile of satisfaction on her face to replace the grimace of pain, and Ginny heard her sigh. Ginny's head darted to Hillary's washboard stomach, as the muscles did a tectonic shift when her hips bucked, rippling in a wave like a belly-dancer.
"Mmmph..." Hillary moaned, bottom lip being chewed, as Ginny heard a dripping sound from the floor in front of her. Still staring at Hillary's iron stomach, she noticed her friend's tiny white panties were now a damp grey. They were tiny against the bulges and sickening swells of her friend's muscles. Ginny's hand trembled at the end of her own surprisingly muscular forearm, her thick cords of muscle twitching quirkily.
She wanted so badly to reach out and just touch Hillary, feel the stony warmth of her giant, vein crossed, bloated stomach, to fill her small hands with as much of Hillary's quivering body as possible - but she was kind of scared what Hillary might do. Just then Hillary exhaled softly, her eyes opening slowly to see Ginny there in front of her on her knees, her muscular arms oustretched towards Hillary's body.

And what a body. Looking lovingly downwards, Hillary could see she was intensely, grossly overmuscled - her chest was a thick, rippling shelf, her tiny bra cups covering only her tiny nipples amidst the slabs of hard beef jutting from her ribcage. Looking to her left, she could see the giant swell of her traps and bull neck, rising in a melon shape to settle right underneath her earlobes. Her shoulder was a two foot wide pumpkin, striated and mapped with veins that slid like worms in and out of the deep cuts. She could not see the size of her arms due to her outrageously giant deltoid muscles, and raised her arm vertical. Arm straight out, she guessed the mass of cut, throbbing muscles to be around two feet in circumfrence. Unflexed! From her delicate hand rose a wave of dancing muscles, her forearm bulging at its apex to sixteen inches. She cooed in delight, and Ginny jerked backwards, until then enchanted by watching Hillary's huge body becoming realized by the teen muscle goddess.
"Ginny, flex," Hillary whispered sultrily,, and Ginny immediately tensed her arm in aqueiscence to the amazon's wishes. Ginny's tanned, smooth arm swelled with her flexing, and a solid ball of muscle the size of an apple appeared on her arm. It was an impressive amount of muscle for a grown woman, much less a girl still in her teen years. Ginny stared at her bicep, then looked up to see Hillary smiling. She bent over, causing a riptide of swelling and receding muscles along her pulsing upper body, and put her arm right next to Ginny's pumped, hard biceps. She curled just her wrist inwards, and her forearm erupted, looking like most bodybuilder's calves when pumped full. Her forearm was huge, and veins now throbbed along the huge bulge. Her forearm alone was noticably larger than Ginny's stone biceps head, and Ginny gasped.
Hillary then began to flex her arm, the huge muscles starting to rumble underneath her skin. Ginny watched in utter amazement, despair, and disgust as Hillary's already tremendous arm began to expand exponentially. Half-cocked, Hillary's arm was staggering - her bicep muscle was so defined Ginny could see the three individual muscle heads forming the titantic swell of her whole biceps. Hillary's bis dwarfed Ginny's head, and she had not even really flexed them yet. Yet more cabled netwroks of veins sprang up from her elbows to carry vital blood to the engorged muscles, and agonizingly slowly, Hillary completed her flex.
Ginny gagged, looking at her freind's monstrous arm, writhing with quivering muscle and vascularity. Ginny's own arm, proud and muscular in its own right, dropped to her side in shame of the mass of teen-girl muscle on display in front of her. This time, there was no hesitation - Ginny grabbed for Hillary's bicep in a frenzy, unable to resist the deep wanting to caress her friend's boulders of strength, to feel the power of her outrageous, hard muscles. Ginny moaned erotically as she cupped Hillary's throbbing, hot bicep in her tiny hands. Her firend's huge arm was immovable, disgustingly swollen and thick. Ginny could read Hillary's heartbeat by the pounding, expanding veins that covered her cannonball arm.
Hillary lovingly began to pump her biceps, and Ginny hung on for the ride. Grunting, Hillary doggedly kept flexing her already huge arm, trying to squeeze every last inch of size from her super body.
The two supergirls were so enraptured with exploring both their own and each other's amazing, muscled physiques that they didn't hear the door open again. Billy, Ginny's young boyfriend from the high school football team, crept down the stairs, eyes widening as he began to see the two girls, Hillary flexing her massive biceps muscles as Ginny lovingly caressed the starnge bulges and swells of her strength. Keeping low, and making as little noise as possible, Billy crept down the remaining two stairs and settled in behind the water heater as Ginny got on her knees in front of Hillary, nearly eclipsed by the girl's amazing girth and width. Billy decided to sit back aqnd enjoy the show, stunned into inaction at the sight of the two girls, who this morning had had not even a hint of the strength and size they now posessed.

"Oh my god, Hillary," Ginny whispered. "i want to be this big, this strong and powerful," as Ginny looked adoringly upwards, she began to run her hands across Hillary's barrel, rocky upper body. "Your muscles are unreal, Hillary," Ginny continued, and her hands fell to Hillary's gigantic pec muscles. The simple contact startled Hillary, and as a result, her chest expanded, crackling, her young breasts skyrocketing out and up atop volcanic mounds of pectoral meat and tendon. Ginny, reveling in Hillary's muscularity, tried to knead her friend's breast, but there was no give - Ginny's grip, formidable as it was, could not dent the mountainous, shifting tectonic plates of muscle breasts in front of her.
Hillary, feeling very alive and cocky, decided to show Ginny up by flexing every muscle she had as hard as she could. She was relishing Ginny's jealousy and worship in different ways, but they both ended up in the same answer - Ginny lusted after her huge, hard muscles, and Hillary loved it.
Hillary took a step back to give herself room. Ginny's hand fell away from her hot stone physique with a sigh of despair. Hillary smiled down at the young musclegirl, on her knees in front of her amazonian, musclebound body. She would give Ginny a show of female muscle like she'd never see again, Hillary thought, and began to harden every muscle in her body. Her tremendous musculature actually shifted, rippling for a second, and then became stone hard and rock solid. Ginny gagged involuntarily at the sight of Hillary's fully pumped, disgustingly developed physique, striated and cut all over with thick, delicious muscle.
Ginny gagged again, as Hillary began to tremble and make strange whining noises from between tightly clenched teeth and a strange painful smile on her small pink lips, from the immense exertion of pumping every one of the multitude of bulging, veiny, sickeningly huge muscles that made up her unnatural seventeen year old megawoman's physique. Ginny could not control her desire in the face of Hillary's blatant muscularity and sexuality, and leapt to her feet, buttocks jiggling slightly in her miniscule panties, and ran to Hillary, wrapping her sinewy arms around the amazon's barrel neck, and pressed her own impressive body against the sweat sklicked, marble warmth of Hillary's amazing temple of a body.
Ginny forced her strong, lithe tongue down Hillary's throat, kissing her friend deeply while massaging Hillary's huge muscle tits in her hands. Hillary tensed up, alarmed, and Ginny's muscular upper body disappeared in a roaring mass of muscles. Hillary's huge arms were wrapped around Ginny's thick back, and her prodigious breasts, tensed and swollen, surrounded Ginny's head ominously. Ginny moaned and tried to wrap her arms in an embrace around Hillary's huge, winged upper body, and couldn't - her hands still had two feet of solid meat between them! Instead, she used her small, strong hands to stroke Hillary's giant, trembling back, carressing the swells of meat that swam across her amazing, grossly overdeveloped teenaged body.

Billy gasped, watching the two muscle freaks holding each other, filling their tiny hands with each other's bulges as their kiss lengthened, multiplying in passion as they groped. Ginny's body was smothered and shadowed by Hillary's disgusting, ultra developed physique. Despite his initial disgust at the sight of his girlfriend in the arms of a giant, muscular amazon of a girl, Billy began to become aroused himself, watching the two in their dance of muscular passion.
Hillary, overcome by Ginny's strong kissing and the feeling of her friend's hands roaming her tremendous physique, filled her hands with Ginny's strong glutes. Her butt was sculpted, hard, and covered by a tiny piece of pink fabric - the rest of her thong was encased by her squared off, muscular butt cheeks. Ginny pressed her thick young body against Hillary's huge muscles, molding her bulging physique against Hillary seductively. Billy was now stone hard himslef, watching Ginny rub her crotch against Hillary's meaty, swollen leg in quick, small circular motions, her ass cheeks swelling and receding with the repetitive motion.
"Oh, Hillary, your body is amazing," she half-whispered, half-moaned. "Your big ... hard.... muscles make me want you so badly," she whined, and Billy could taske no more. He sprang from the hiding shadows, betrayed and angry as he had ever been, and stopped cold in front of the two muscle girls.

"What the fuck, Ginny!" Billy stammered, clearly intimidated by the obvious strength of the two teen bodybuilderettes, visibly sweating and continued, "First off you build a bunch of sick...." he looked up and down Ginny's glistening, rock hard physique, amazing in its own right and cut to shreds, but dwarfed by Hillary's mass next to her, "muscles....." he trailed off, as he was now only a step away from his musclebound girlfriend and the new object of her desire, his high school classmate, Hillary. But the Hillary before him now was gigantic, a true teen Amazon, bigger by far than any male bodybuilder, football player, or athlete he'd ever seen. Even though she was hugely muscled, masculine looking in body and covered in thick, cabled veins, there emanated from her an unexplainable sexuality, a blatant disregard to what normal femininity could be counted as. Her rigid girl muscles were gigantic, swollen, and extremely hot, and Billy found himself speechless, standing in front of Hillary with his fists clenched as his girlfriend began to remove herself from Hillary's muscular temple of a physique.
"Billy!" Ginny cried, her small hands frozen on Hillary's washboard stomach. "It's not what you think," she trailed off, realizing that her hands betrayed her voice, and removing them reluctantly from Hillary's warm stone body.
"Not what I think!" Billy yelled, "didn't I just hear 'your big hard muscles make me want you'? Yeah, not what I think, bullshit, Ginny!"
"But Billy, look at her!" Ginny whined, pointing at Hillary. "Hillary, flex for Billy, please," she pleaded, wanting to prove her case to her boyfriend. Ginny's almond eyes fell on Billy's as Hillary began moving, muscles rumbling. But to Billy, Ginny almost ceased to exist.
"Look at my big muscles, Billy," the teen goddess began, her voice low and silky. Hillary blew a kiss to him with one obscenely muscled arm. She then placed her finger in her mouth and slowly, seductively flexed the ball of muscle in her huge biceps. Her arm exploded with size and veins, and Billy's mouth opened slightly. He felt his dick stiffen instantly, and Ginny had her answer, even before Hillary vacuumed in her rippling stomach and blasted outwards with a staggering 14 pack of cubed veiny muscles.
"See, Billy, you do like her muscles, just like I do," Ginny giggled, and placed her hand on Billy's shorts. "You like her muscles a lot, don't you Billy?" she cooed, running her hnad down a larger and thicker, harder Billy than she had ever seen. The fact that Billy was getting incredibly hard simply looking at Hillary's massive, frighteningly huge muscles didn't bother Ginny at all, it actually excited her even more than the effect of the teen amazon's muscles had had alone.
"Jesus, Billy, you're gigantic," she whispered softly, delighted, and beamed upwards to Hillary, slowly stroking Billy through his shorts as Hillary pumped her swollen pecs, making them dance for her young worshippers.
Billy's eyes were wide open, even his mouth open slightly, and his manhood huge and stiff. In front of their new joint object of muscle lust, Ginny pulled the waistband of Billy's shorts from around his enormous pole. Ginny grasped Billy's throbbing member in her small hand, stroking its tremendous, quivering length as Hillary posed slowly and sexily for her greatest fans. Both of the teen's eyes were glazed over, and Ginny was licking her lips as they atred rapt and watched Hillary flex her giant muscles for them, giving them a private muscle show. Hillary proceeded to both sicken and arouse them alternately, with a tremendous, outrageous display of female muscles like the world has never seen before. Her body deformed and swelled awesomely, and each bodypart was given a full exhibition, raising thick veins all over her young, robust physique. A slick of sweat coated her every exposed inch, accenting her huge bulges. Billy was in ecstasy, being hand jobbed by his muscular girlfriend while his eyes could feast on this icon of strength, this teenaged muscle goddess, who was bloating her massive body for them like a circus show.
Ginny was also intently watching Hillary bloat her disgustingly huge and ripped physique, stroking Billy's throbbing hot member with one hand while slowly and softly caressing her bikini bottoms with her other hand. As Hillary hit a crab pose, causing her inflated musculature to explode to a new height of bursting rigidity, Ginny moaned in desire, and Billy noticed her now vigorous, quick rubbing, and tried to ignore her masterful skills in masturbation long enough to pull the string thong off of her tight, ridged glutes. She bucked her hips, moaning, and Billy was treated to the sight of Ginny's rippling abs trembling and forming a pebbled wall of teen muscle. Mad with lusting for the two musclegirls in front of him, her pried Ginny's surprisingly strong hand from his shaft and moved to a better position for viewing both of the hyper-developed young musclegirls.

Billy penetrated Ginny from behind, his hands roaming the rips and swells of his griflriend's sweat slicked, meaty body as he punctured her womanhood with nearly a foot of himself. Hillary exhumed power, standing one foot in front of him, her swollen body and pumped lats filling his field of vision. Ginny moaned as he entered her, her face getting buried in Hillary's crotch. Billy watched as his girlfriend performed voracious oral sex on Hillary, and Hillary herself began to moan, her hips gyrating with Ginny's tongue's pace. This caused her already extraordinary stomach muscles ripple and stretch, doing a belly dance of etched blocks of ab muscles. Billy pumped harder, mercilessly, and Ginny's mopaning became louder, and constant, growing with the second as Hillary began to flex for both of them. Ginny's eyes locked as Hillary bounced her disturbuingly huge pecs, her tiny nipples flying around in a jumbled mass of hard, ripped muscles. Her jaw was moving quickly, giving pleasure to the amazon teen in waves of ecstasy. Hillary performed a lat spread that eclipsed both Ginny, bent over and moaning, eyes beginning to roll back in her head, and Billy, who was drooling freely down his chin while he simultaneously filled his vision with Hillary's behemoth muscles and ferociously fucked his young, robustly muscled girlfirend.
"Oh, Oh, Oh," Ginny began to moan in conunction with the meaty sounds of Billy pounding her tightly muscled backside. Hillary's juices were all around her mouth, glistening in the dim lighting. Hillary did a most muscular pose, her distended muscles rumbling into prominent, powerful swollen dominance. Her upper body was gigantic, her womanhood dripping, and her legs looked like someone had surgically inserted hams into her thighs. Looking down with a satisfied look on her young face, Hillary saw Billy's eyes nearly popping out of his skull, his mouth wide open in an erotic combination of fear, lusting, and amazement. Ginny, meanwhile, was now panting like a dog, her tongue wagging as strange moans and grunts emitted from her. Still, her wide eyes never left Hillary's explosive body, quivering with her tremedous crab pose. Billy was jerking, shaking as he awkwardly continued to thrust his large manhood in and out of Ginny's tight, wet vagina while watching Hillary expand her sweat covered, veiny, and irreconcilably humungous teen muscles for him.
Hillary, her entire body warm and incredibly pumped, was loving every second of her muscle worship session. Ginny was merely a hole for Billy - he was fucking her in his mind, she was sure of it by the ravenous, almost manic look in his eyes. She looked deep into his eyes, and flexed one massive biceps head. Her rippling arm ballooned to gargantuan proportions, jumping quirkily, making the cables of veins appear to writhe under taxed skin and atop bulging power.
"Does that make you hot, Billy?" she whispered, unblinking, staring at Billy's huge manhood ramming in and out of Ginny like an engine piston. "Does my big girl muscle get and keep you hard?" Hillary was now pumping the huge muscles of her arms, trying to milk yet more pump, definition and sickening size into herself. Billy was literally foaming at the mouth as Hillary seduced him with silk whispers and helplessly erotic, gigantic teen muscle, inches from his face and throbbing with heat and power.
"Uhhn, Uhnn, Mmmph..." Ginny groaned in delight as her boyfriend was wooed by Hillary's forboding, superheo-like musclewoman's physique. Ginny's own muscular monument of a body was covered with a sheen of sweat, and her breasts jiggled slightly atop her prodigious mounds of pecs inside the tiny bra with her rocking movement.

"Feel my arms, Billy," Ginny moaned, begging, and arched her strong back, making her lithe upper body explode with thick, strong muscle. The arch made her small breasts jut out sexily, mounded on top of swells of pectorals, followed by her distended, stretched and cubical abdominals. She brought her arms into a double biceps flex, and they expanded before Billy' and Hillary's eyes into striated, rock hard arms that had much more place on a male gymnast than on Ginny's young body.
"Ooooohh.h......." Ginny hitched, almost hicupping, overwhelmed by the simultaneous pleasures of stretching and expanding her til then dormant muscles, and from Billy's fierce doggy styling from behind. Her body shook in a slight orgasm as she locked her bicep flex, holding as hard as she could. Her arms became covered with thin veins, like spiderwebs, raising a roadmap all over her swollen arms. Hillary looked down in envy at Ginny's incredibly sexy, striated and cut body, bumping to and fro with each long stroke of Billy's stone hard cock inside her. And then, to Hillary's dismay, Ginny began to grow. Her already freaksih muscles swelled, alarmingly fast, erupting from her arm in a growing, softball sized mound.
"Mmmmmph!" she moaned in satisfaction, and looked over to her rippling arms. Her blue eyes blazed wide at the sight of her guns, beginning to tremble with the flexion, and starting to approach the size of Hillary's own massive arms. Ginny's eyes were half-lidded in pleasure as she looked up to Hillary's huge, quivering musclebound young body.
"I'm getting bigger, Hillary," she cooed, eyes now blazing with the jealousy and confidence her growing, swelling muscles gave her. "I'll be just as big as you are, ooooohhhhh....." Ginny moaned loudly and Hillary watched fascinated as her chest swelled visibly, erupting twin volcanoes of thick pec muscle, making her top billow in aquiescence to her growing pert breasts. She now looked a large C-cup, but Hillary knew that her real breasts didn't even fill an A. Her tremendous body became unreal, thick balls of muscle standing angrily out all along her body.
"Billy!" Ginny gasped, but in a commanding voice, "I said FEEL MY ARMS!" Ginny's upper body trembled with another growth spurt. Hillary watched, horrified, as Ginny's shoulders broadened before her eyes, her already tremendously muscled arms swelling with unnatural, rippling growth - her skin was stretched like saran wrap across her thick, ropy and bulging biceps and triceps.
Hillary's eyes traced down to her diamond cut abdominals - thick cables of veins criss crossed Ginny's swollen, muscle laden stomach, snaking amongst the full, striated fourteen pack Ginny's arched position showcased. Hillary's eyes locked on Billy's - he had stopped his frantic thrusting when Ginny began to yell at him - fear of her rumbling, still swelling physique froze him. And Ginny was right - the young girl's muscles were truly huge now, and Hillary thought Ginny's arms might just be thicker than her own gigantic guns. With a slick pop, Billy's huge, trembling manhood slipped out of Ginny as he leaned backwards, falling over onto his back.
"Fuck you, then, Billy," Ginny purred, and ran her hands along the disgustingly huge swells of her abdominal package. She started to stand, looking at Hillary as she did. Her thighs erupted with thick rippling muscles as weight transferred from leg to leg. Swelling and receding, Ginny finally stood and looked up at Hillary. Gone was the earlier look of worship on her face - now Ginny looked smug, her pink lips pursed pertly, hand one one giant swell of glutes.

"And you, Hillary," she said slowly, "Looks like you're not the biggest now," Ginny cocked an arm and flexed - her biceps erupted, indivudal sinews and balls of muscle appearing to form a frighteningly large, cut as a diamond head of meat. Veins covered the muscle angrily, looking like tiny writhing snakes when Ginny started to flex it harder, pumping her lower arms and inch and no more. Impossibly, her bis became even more cut, and Hillary thought she could see the strands that actually made up the swollen muscle bellies.
"So, once again, Hillary, I end up being better. Like always," and this said, she lowered her unnaturally muscular arm, swung her hips coquetteishly, and turned her head. "Billy, get your stupid weak ass over here and do as I said. I'm the biggest, strongest girl now that you've ever seen - I'll be in control from here on in, not her ugly ass," she dropped a sly wink in Hillary's general direction, and the ultra-muscular teen girl could take no more.

Hillary swung a viciously fast punch with all of her considerable might. The fist connected true, instantly breaking Ginny's jaw in five places - Ginny's bull neck, thick and corded, did not give an inch, and so her unprotected jawbone took the huge impact alone. Ginny began to moan, intersperesed with loud cries, as Hillary jackhammered her fist all over Ginny's face, splitting the gorgeous girl's lips, blacking her eyes, and breaking her nose with a loud snap, like stepping on twigs in the forest.
Hillary began to laugh as she punished the younger, unbelievably stacked and beautiful body builderette. Each blow she unleashed on Ginny's body and face, each crack of bone on bone, sound of bone breaking, and resulting cries, moans and yelps of pain were in revenge for her constant perfection - for everyone's attention on Ginny, on Ginny's athletic body, on her personality, and now on her disgustingly, massively developed muscular masterpiece of a physique.
Ginny screamed now, writhing beneath her as she rained powerful, bone breaking blows with her rumbling, hugely muscled arms. Billy cried like a baby, his eyes locked on Hillary's swinging, veiny breasts, which pistoned, swelling and receding with each thunderous punch. Hillary was basted with sweat, rivulets of clear liquid cascading down the craggy landscape of her chest and pulsing abdmoinals. Finally, Ginny fell, her brain shutting down against the pain surging across her powerpacked, musclebound physique like waves. A loud thud echoed in the basement when she fell, a smack of meat against concrete.
Hillary put one foot atop the broken young teen girl and flexed her massively prodigious guns. Billy's eyes, wet with fresh tears of fear, instantly locked on Hillary's bursting biceps, striated and incredibly veiny from the workout. With her arms flexed, she spoke down to Billy.
"You want this body, don't you?" she purred, feeling uncontrollably dominant, her muscles pumped up, veins throbbing on her beefy arms and pecs, as she curled her arms, looking from bulge to bulge as they swelled. Hillary then put her thick forearms behind her head, and blew Billy's mind. Her already rippling abdominal wall swelled outwards, cubing, as her breasts came to proud attention. He groaned slightly, and thought he was going to come for sure, right then and there.
Hillary pumped her chest muscles alternately, making a huge wave of meat surge and drop with every second. At the top of the flex, her breast flattened out a bit below her nipple but blew up like it had a pump attached above it. The sight was amazing - Hillary's breasts grew by two cup sizes with each flex, surging upwards and inflating like balloons, but there was no give in these, they were filled solid with bulging, rock hard muscles. Her abdominal wall remained stone hard flexed, the bubbles of concrete muscle shifting slightly with her breathing. Billy was fully mesmerized again at the hulking physique now starddling him, locked, bulging, in a massive latspread, Hillary's angelic face looking down to his manhood and smiling in delighted reaction to his obvious state.

"Watch this," Hillary purred, and began to squat down onto Billy's big, erect manhood. Billy watched in utter lusting as Hillary's meaty, swollen physique descended upon him. Hillary began to take inch after trembling inch of Billy inside her, and Billy was amazed at her tight vagina as it actually felt like he was being swallowed by her. Finally, with an added licking of lips and a soft sigh, the young musclegirl finished her sex squat, her thighs huge, swollen with blood and thick veins, and had Billy completely inside. Then, amazingly, she raised herself up slightly,her big, muscular legs paralell to the ground in an awkward squatting position. Hillary's legs trembled at the weight they supported, both her massive body and Billy, hanging from her vagina like he was attached. What happened next was the most overt, unnatural display of muscular control - Hillary actually used her vaginal muscles to thrust Billy in and out of her - never losing the vise like grip around his cock. He moaned, and Hillary responded.
"Do you like that, Billy? Do you like being fucked by my big, swollen," she sighed and moaned slightly herself, the feeling of Billy inside her making her tremble. "....muscles, Billy? Ooooohhh.....Unghh....." Hillary sped up, and Billy flailed like a rag doll as he was forced in and out of Hillary's moist, ridiculously strong vagina - his entire field of view was eclipsed by Hillary's Amazonian physique, pumping him in and out of her like a sweat-slicked machine. He felt himself both getting physically ill and simultaneously nearing a volcanic, muscle-fed orgasm, and began to moan. Hillary smiled down at him, and he was finally held in one place, still, underneath her. Her body looked like an oak to him, straight above his head, massive swells of ridiculous meat, massive girl muscles, veins, sinew, and sweat.
To finish him off, she used her internal muscles, as developed as the evident, huge swells on the outside. Hillary greedily struck gigantic, horrifyingly muscular poses as her unbelievably developed, superstrong vaginal muscles did the work on her young sex toy. Billy screamed in both pain and pleasure as he felt his big, stone-hard penis being rubbed like a glove, and then Hillary dropped him unceremoniously.
With the thud of contact with the hard flooring in the basement, Billy could hold back no longer and came in streams, shaking and moaning in low to high volume as his muscular mistress performed a gigantic lat spread on top of him.
Hillary watched over all of this, her frame swollen and deformed with gigantic muscles, and bit her lip as she came again to intense orgasm - her juices quickly seeped through her already wet bottoms and shellacked Billy's face as he passed out from complete sexual exhaustion. His last sight was Hillary's trembling, unbelievably thick and hard body, fully flexed in her state of pleasure, looming above him.
