Matt Grows for the Girls

[mman]

This is a new spin on an old story.

It was the last week of summer. A new year in a new school lay ahead.

Matt was going to begin his Junior year at Valley High. He was anxious about going back to school.

Matt was what people often called "stocky." He had yet to have one of those growth spurts so many of his classmates had had. He was still only 5'2" tall. He had a fairly average body, a little thick for his height, but not fat. With an open face, dark brown curly hair, and big brown eyes, his older relatives sometimes called him cute as well.

Despite being high school age, Matt really hadn't started puberty yet either. He barely had little wisps of hair in his armpits, and almost no pubic hair. His dick had yet to start maturing either - and was short, in proportion with the rest of his body. The boys in the locker room teased him and called him "stubby" when they saw him naked.

As he pulled his bicycle into the family driveway coming from his summer job, he saw his step-sisters watching their boyfriends playing basketball up near the garage.

Matt was the youngest of the siblings in his family. His step-sisters, Jessica and Lisa, were fraternal twins. Each of them was popular at school, having just finished their senior year at Valley. Their boyfriends Jeff and Jason were big men on campus too. Both were going to college on sports scholarships this fall.

Jeff had been a tight end on the football team. He was 5'10", and built like a young bodybuilder. He spent hours in the gym working on his body, and never wore anything but tight tee shirts or tanks tops.

Jason was a little taller than Jeff at 5'11", but not as massive. He had been Captain of the swim team his senior year at Valley. He had the long lean muscles of a swimmer. If Jeff was considered good-looking, Jason was considered gorgeous by all the girls at school.

But, they were boyfriends of Jessica and Lisa, two knockouts themselves. Jessica was a cheerleader at school, blonde haired, blue-eyed bombshell. She loved wearing tight, cropped shirts that showed her large breasts and smooth but soft belly. With her year-round tan, she was a sultry Britney Spears. Lisa was breaking into professional modeling with darker features and a little more height. She was tall and thin and accentuated Jason’s physique with her statuesque qualities. With brown hair and eyes, she was not as obviously pretty as Jessica, but more mature and beautiful.

As he got off his bike, Matt wondered what life would be like when his step-sisters left for college with their boyfriends in the fall. Although he hated their merciless teasing, he would miss seeing them every day.

"Think fast!" came the warning as Jeff hurtled the basketball at his face. Matt caught it, but just barely. He took a shot at the hoop, but as usual, his shot fell short, hitting the side of the rim and bouncing out into the lawn.

"I told ya not to bother with him." said Lisa. "Stubby's too short for basketball"

"Yeah, what're we gonna do with you, Stubby?" added Jessica. "And
when you gonna start growing'?" Matt just ignored them and walked into the house.

"Things have gotta change!" he thought to himself. So he threw his bike in the garage and went into the basement for some alone time.

Matt liked to be alone in the basement. This is where he did his best work. You see, Matt was an aspiring chemist, with more than an amateur’s set-up of equipment, even though he was at a young age. Understandably, he had recently become fascinated with the growth of living things and had successfully developed chemicals that helped plants and animals like fish and gerbils to grow quicker and larger than normal. He had reached the point in his research and frustration where he was ready to try the serum on himself. What did he have to lose? He was going to be ridiculed by the school for four long years if he stayed the way that he was, and he didn’t want to live like that.

He picked up a test tube of blue liquid in the darkened cellar and drank its bitter contents. He expected no immediate reaction as all his experiments grew over time. He began to feel sick and went back upstairs to sleep.

As the week went on, Matt forgot about the serum, becoming more and more anxious about going back to school. On Labor Day the entire family was spending the day at his Uncle Frank's house. Uncle Frank was kind of rich, and lived in a big house with a pool. Hanging around the pool, Matt noticed how his step-sisters had developed over the years. Jessica was showing off in a yellow string bikini that looked like three triangles of fabric holding in tall, round hills of flesh. Lisa, who had spent the first eight weeks of summer studying and working out at a modeling school, looked like a runway goddess. She was wearing a skimpy, black, two-piece bathing suit, and the bottom of it was a thong that made her ass look like something you would die to take a bite of. The day progressed, with their boyfriends and Matt’s cousins rough-housing at the pool. They frequently picked on Matt to be "it" in their games. Once, Jeff even "pantsed" him, pulling down his jam shorts, and then teasing him about his stubby dick in front of all the cousins.

That night, Matt went into the basement for another dose of his potion, but was unable to take a swallow before Jessica and Lisa came down to work-out. Just like Matt kept his equipment downstairs, so did the girls with their exercise machines. Matt ducked behind a stack of boxes with his test tube so that the girls could not see his, and was trapped there for their entire hour-long routine. He watched as they stretched and sweated in their boyfriend’s T-shirts, tied high around their tits and abs, and short, tightly hugging their asses. At the end of their routines, they removed their shirts, thinking they were alone, to dry off with a towel. Matt was stupefied by his gorgeous sisters and thought how lucky Jeff and Jason were to have these girls going off to school with them. As he wiped the unrelenting sweat from his head, he clumsily knocked over the boxes he was hiding behind and was discovered by the topless twins. They quickly threw on their shirts and grabbed their step-brother by the neck of his as his test tube crashed to the ground. "Who do you think you are staring at us? I always knew you were a worm of a man, but never knew you were a pervert, too." barked Lisa. Usually Jessica was the aggressor of his two step-sisters. It was even worse now coming from Lisa.

Jessica chimed in "Maybe we should have Jeff and Jason teach him a lesson so that he knows not to mess with women out of his league!" With that, Jessica grabbed Matt from behind, holding his arms behind him.

It was all too much for Matt. He didn’t know what the girls had in store for him, butt here was no way he was going through any more humiliation. He started to squirm, and twist. He couldn't get free. And Jessica was really starting to hurt him. Lisa picked up her cell phone to dial the boys’ number.

Matt started turning red. He heard a buzzing noise in his ears. He felt hot and cold at the same time, and sort of dizzy too. Suddenly, with a huge burst of energy, he pulled free from Jessica.

"I have had enough!" Matt just stood there, panting. He felt so weird. And his step-sisters were looking at him like he was from another planet. "What the hell are you staring at?!?!?"

Suddenly, Matt felt different. He felt like energy was coursing throughout his body. He hurt all over and felt great at the same time.

He realized he was changing. He was getting taller by the second. And his body was filling out. His shirt no longer was tucked into the waist of his jeans. And it was skin tight. His jeans were tight too.

He ran to the mirror Lisa used for posing, and watched himself. He was literally rippling all over. He was at least 5'8" now, taller than both girls, and looked like a little bodybuilder. He flexed his arm, and his bicep ripped his shirt sleeve! What a feeling!

Matt started grunting, and swearing. "Shit yeah, this feels great! Look at those muscles!" All the while, his step-sisters just stared at his reflection in the mirror, their mouths hanging open.

Matt continued to grow. Rrrrrriiiipppppp. There went his shirt entirely, as his lats popped out, splitting the shirt down the back. Small mountains of traps grew on either side of his neck, while his shoulders took on the shape of bowling balls.

As the shreds of his shirt fell away, Matt ran his hands over the solid bricks of his 8-pack abdominal muscles. He struck a most muscular pose for the mirror, and growled with pleasure at what he saw.

RRRRiiiippppppp!! There went the legs of his jeans. Huge quads now bulged through the rips in the legs of his jeans. The calves were so tight he was sure they were gonna rip too. The jeans were also constraining him, because as he grew taller, they were way too short. The cuffs of his jeans were now like rubber bands around his upper calf muscles. Matt couldn't take it anymore. He reached down, and with an animal grunt, he ripped the rest of his jeans right off his body.

"Holy shit!" he heard Lisa whisper in a voice that sounded like she was both excited and terrified.

Matt turned back to the mirror. What a sight! He was now taller and more muscular than Jeff and Jason, and could enter any body building contest in the country. And he wasn't done growing. He stood there in white sweat socks and white fruit of the loom briefs that looked like bikini underwear because of the way his leg muscles made them bunch up. And it looked like there was a softball stuffed in the crotch of his shorts.

Matt reached down, pulled the waistband of his briefs away from his body, and peered inside. He couldn't believe what he saw inside. With a cunning grin on his face, he turned from the mirror to face his step-sisters. He slowly hooked his thumbs in the waist of his briefs, and began to slowly lower them. With a sudden jerk, he pulled the briefs all the way down to his knees, stood straight up, and let the shorts fall to the ground, where he kicked them aside. Eight inches of thick rubber hose dick bounced at his groin, arching forward over testicles as big as tennis balls. Each of his step-sisters gasped.

Matt felt the intensity of the changes in his body begin to slacken off. He knew the changes must be almost over. He suddenly thought of his last experiment, and the serum he had taken. "I knew the reaction would be delayed, but I had no idea I would get so huge, so fast" thought Matt.

"I think things are gonna change around here!" announced Matt to his
step-sisters. Damn, he loved his new hot sexy deep voice. Matt stepped forward, and grabbed each of his step-sisters by the upper arm. At 6'2", he towered over each of them. He easily pulled them towards himself. "I think you girls owe your little brother an apology!"

"What do you want us to do?" asked Jessica. Lisa quickly decided it
didn't matter, and lunged for the stairs. Matt caught her easily. He grabbed her by the waist, picked her up off the ground, and threw her on his lab table.

"There's no getting away from me. I think you girls should make up for all the torment you've given me." With that, Matt grabbed Jessica, pulled her close, pulled her head into his huge pec, and demanded "Lick it!" When Jessica hesitated, Matt lifted her off the ground by the shirt collar, pulled her up to eye level, and said "You have no choice. Now give my body the tongue bath it deserves, or I'll pound the shit out of your jock of a boyfriend!"

He lowered Jessica, and once again pulled her head close to his massive chest. Jessica whimpered, and started licking. Matt moved Jessica's head around, making her service both pecs, and the big cleavage between them. He would pull Jessica's head in real tight, then flex his pecs, smothering Jessica's face in solid muscle. At some point, Jessica no longer needed to be coaxed. She seemed to enjoy it, moving around the muscle stud's giant body, asking Matt to flex his biceps, which he licked and nibbled. Jessica really started to worship his giant stud brother. She licked Matt's huge biceps, moving under to the triceps, then diving her head into the armpit. A smile crept across Matt's lips as he realized Jessica was turned on by the thick bush of hair that had sprouted there. Jessica continued to move all over his upper body, her hand rubbing one body part while her tongue worked another. What a turn on to feel a woman lick, then even lightly bite, his huge wing-like lats. A low moan came from Jessica as Matt flared out his lats in a lat-spread.

Even better was Jessica's reaction to Matt's abs. As Matt flexed his mid-section, Jessica tongued each and every brick like muscle of the 8-pack. Her hand never left off cupping and squeezing the huge pecs above. Matt felt like he now "owned" Jessica.

"Now its your turn!" said Matt turning to Lisa, who still lay on the
table where Matt had thrown her. Lisa appeared unable to speak, and was trembling. "Quit acting like a baby, and get over here." Matt
ordered.

Slowly, as if in a trance, Lisa stood and took a step towards Matt and Jessica. Jessica paid no attention, and continued to murmur and make cat-like mewing sounds; She was obviously enjoying tasting every muscled inch of Matt’s muscular, hot body. Lisa, on the other hand, just stood there.

Matt reached out his free arm, and grabbed Lisa, pulling her closer. Then he put his hand on Lisa's shoulder and pushed down. Lisa tried resisting for a second, but it was impossible. After a second or two, Lisa was forced to her knees.

"I think you should service my new monster cock!" announced Matt. With that, he grabbed the back of Lisa's head, and pulled it towards his crotch.


Lisa felt like a zombie as her face was brushed by the python sprouting from her step-brother’s groin. "Take it in your hands, then lick it!" came the orders from above. The cock seemed to be alive - almost nine inches long now, and still totally soft. Lisa reached out and took it by the base. It was heavy. Suddenly, pushed from behind, her head tilted forward, her open lips brushed the shaft of the penis. As if a trigger for action, Lisa suddenly came alive, reached up with her other hand, and started stroking the massive member. She couldn't get her hands around it. It was too thick. Nonetheless, the big meat started to really come alive.

Waves of pleasure washed out from the center of Matt's body. This was too much! He could feel the blood pouring into his dick. It was slowly thickening and lengthening, growing to truly gargantuan size. "Take the head in your mouth!" he ordered Lisa. Lisa did so, and was barely able to get her jaws open wide enough.

More and more blood poured into Matt's huge cock. His step-sister looked up at him, eyes watering, and drool streaming from her mouth, which was stuffed with the huge prick. And it just kept growing. Jessica finally took notice of what was happening, and looked down at the tower of flesh growing from her step-brother's midsection. Without any orders at all, she looked up at Matt's face, smiled, then fell to her knees, and joined Lisa in working on Matt's huge fuckpole. Lisa continued to choke on the head; and the sound of gagging filled the room. Jessica began to rub Matt's balls, while she licked along the shaft like it was a corn cob. Finally, Matt sensed his dick was rock hard, and would grow no bigger.

It was all too much for Matt. He looked down at his step-sisters' lust filled eyes, then back up into the mirror at the reflection of the awesome god-like stud he had become. He pulled his step-sisters away from his dick, grabbed the shaft, and started pumping. He groaned and grunted as he worked his meat. Pre-cum began to flow in a steady stream. It felt so good. So hot! SO AWESOME! He watched in the mirror as all the muscles flexed and bunched while he worked his meat. He noticed his step-sisters' were feeling themselves up, squeezing their tits and rubbing the enormous wet spots on their shorts and they were muttering encouragement like "yeah, do it" "shoot that load" and other hot comments.

He began to feel his new huge balls tighten up under his dick. He could tell he was gonna shoot.


"AAAARRRRRRRRRRRGGGHHHHH!!!!!!"

He let loose a howl, and started to cum. Blast after blast of white thick cream erupted from his monster meat, showering both step-sisters who just sat there, getting coated in jism, and staring in amazement. Spurt after spurt kept shooting from his cannon, and it didn't appear to let up. Finally, it began to subside. Even as it slowed, one long continuous stream poured slowly from the softening meat, forming a puddle at his feet; one long strand stretched all the way from his dick to the puddle.

Matt felt incredible. He must have cum quarts. Jessica looked like her hair was full of shampoo. Lisa just sat there, with so much cum on her face and chest, it looked like ten guys had shot their loads on her. And that wasn't all - it was dripping down the mirror in several places too. What a load!

Matt looked into the mirror again. What a sight. He looked so hot. His body was coated in a sheen of sweat. His half-hard dick hung out in front of his body, with a long strand of cum still hanging from it. He straightened, and flexed his arm. His huge bicep jumped up in response. It was all so hot, he started to get hard again. With a smug smile on his lips, he lowered his eyes.

"Like I said, girls, things are gonna change around here. And I think the fun is just getting started!"

Great story. Read the original, but I like this alternate perspective even better.

[GrowinHuge4U]

Especially if this is a man 4 man site.

[mman]

My understanding was that this is a Male Muscle growth site. That is exactly what the story I adapted contains, Male Muscle growth. And judging by the number of times my post has been read, not many guys who frequent this site object to a story about a guy getting huge including women.

Am I wrong?

[iceman75]

of course I consider myself straight, and I usually come here just for a certain kind of story, which I haven't seen on here for a while, but seeing a hetero story is just as good in my opinion. My main fetish when it comes to male muscle is kid muscle, like Damien, Big Little Bro, etc, but I love muscle on all women, maybe there should be a muscle woman in a muscle man story somewhere down the road. I hope this won't get a bunch of backlash, I don't want to say that I hate gay people, I just don't read muscle stories for gay sex! There needs to be more hetero stories on here, so keep it up MMAN.

[arpeejay]

You're right. It's male muscle growth, regardless of orientation. I'm gay, so I can't say I'm particularly interested in most straight sex stories, although the Tony series tends to work for me whether he's fucking guys or girls.

I would guess mine is not an uncommon opinion here.

[AngryLeek]

I welcome the heterosexual twist - it's a nice change in pace for those of us who are bisexual that love Male muscle growth. Anyway, Good re-envisioning of this story, i wish you good have expanded the girl's desire for Matt & actually culminated it with Matt fucking them.

thanks again

[Logan2009]

[Maverick0095875]

Yeah everyone knows, but this story was posted back in 2003! Even if it's removed now, the author certainly can't be blamed.

[Maverick0095875]

You're right, I'm sorry. I've just never seen it before. I assumed it was new when I read it.

[chase0300]

This is a great twist here on the forum and we need more like it.

[inm]

Great story! I'll join the group of people liking the hetero angle of muscle growth, and besides, its written well. I like stories dense with muscle.

[mman]

I haven't cruised the boards in awhile - but it's cool to see my story still being read. I changed a bit to make it more age friendly - don't think it messes with the rest of the content that much.

[charliepanayi]

I remember loving this story, nice to see someone resurrect the thread
