Sibling Rivalry – Part 19: Dayton’s Discovery

[kenstaff]

All other parts of this story



The sight of Dwayne's little brother approaching him with a hungry, zombie-like stare made him slam his bathroom door shut, lock it and lean against the door as if bracing it in panic.


Temporarily cut off from the pheromones being emitted by his older muscle-brother, Dayton stopped a few feet from the door.

“Dwayne? Yew awright ‘bro?” asked a concerned Dayton at the bathroom door.

“uh… yeah… Ahm faan don’t chew worry nayow. Gowon’ git. Ah got stuff tuh dew” answered Dwayne from behind the bathroom door, his voice clearly deeper than before. Dayton however, hadn’t noticed after being distracted by the new gadget on the floor by his older brother’s bed.

Dayton picked up the new phone and played with it, until noticing the open box on Dwayne’s bed. He picked it up and looked inside but found it empty. Unhindered, the younger brother shook the box in hopes something had been left behind and heard a rattling sound. He looked back slyly at the bathroom door and then quickly left his older brother’s bedroom with the box and without realizing it, his phone.

“Dayton? Dayton! … hulllo??” called Dwayne from the bathroom. He then opened the door just an inch to peek out and see if the room was empty and then opened the door and exited his bathroom and made a quick pace towards his bedroom door and closed and locked it again.

Dayton entered his own bedroom and closed his door and shook the seemingly empty box again and smiled at the rattling sound. He then realized he was holding Dwayne’s new phone in his right hand as he shook the box and just as he did, a small instruction booklet and a folded piece of paper dropped out onto the floor. The 12 year-old put the phone and box down and picked up the booklet and paper. Seeing the booklet was instructions for the phone, Dayton tossed it back into the open box and opened the folded paper and read it.


Dwayne,

The sample bottle contains only 2 capsules of Flexadrinazine for you to try to get a feel for what’s to come. Be very careful not to take more than 1 capsule per week as it is very potent and you don’t want to overdose. 2 capsules is more than enough for you to grow significant muscles and earn good income on my premium pay webcam chat. Be sure to hook up your webcam 1st so that you can earn income by taking your sample capsules. Members love to watch teenagers grow before their very eyes and will surely pay large sums to witness it. If you like the effects of my Flexadrinazine and want to continue our arrangement, simply call the number below and follow the prompts for my automated system to automatically deliver more capsules to you. If you don’t want to continue with our arrangement, that’s fine. All I ask is that you return the phone and wireless webcam in the box to the return address – also listed below.

Good luck and hopefully we will talk soon.

Mr. Z

By the time Dayton had finished reading the note, his eyes were wide and his tongue was hanging out with a droplet of drool just about to drip from the tip. He retrieved his tongue just as a drop of his drool splashed onto the note, right on Mr. Z’s Flexadrinazine order fulfilment number. As if on queue, Dayton immediately grabbed his brother’s new phone and dialed the number.

After a single ring, Dayton heard an automated voice answer.

Dayton frowned and looked at the phone, then back the paper and quickly realized there was a code beside the number and entered it

Dayton frowned and realized he didn’t know their family’s zip code and was unsure what to do.

Dayton put the phone down and was about the exit his bedroom in search of some family mail when he realized it was a smart phone and he could find their zip code on it. He picked the phone back up and after a couple of minutes searching, found their zip code using Google and activating his location. He returned to the phone app to the familiar sound of the repeating automated voice.

When Dayton heard a click, an excited but sly smile crept across his face as he wiped his finger-spots off the phone’s touch screen and placed it back in the box, along with the booklet. He folded and stuffed the note into his pocket and exited his bedroom and left the box and its contents outside his brother’s bedroom door and then returned to his bedroom. The 12 year-old stopped himself at his bedroom door and looked down at his crotch to see something he’d never seen before – or felt. His pants had a bulge in them. The feeling he had was one of excitement and he knew it was from what he had done – and hoped to do, after getting the delivery tomorrow. The bulge in his pants however, was perplexing and he wanted to find out why his penis had become hard with an overwhelming urge to touch it.

Dayton turned from his bedroom entrance and instead, entered the bathroom and closed the door. The 12 year-old looked at himself in the mirror and touched his bulging crotch, enjoying the feeling of the hardness of it. He turned one way, then the other to see his profile and how big the bulge was and the sight made him further excited. His mind was filled with muscles and the thought of his older brother and how he’d taken pills that gave him bigger muscles. Suddenly he felt his erection throb in his pants and the feeling made him pull down his pants and underwear.

Dayton’s eyes bulged at the sight of his own hard on, seeing it for the first time. Never having had an erection before, Dayton was unsure what to do but knew one thing for certain – he wanted to touch it and when he did the feeling was so amazing he started to stroke it and his other hand quickly joined in the fun. With thoughts of his muscled up older brother in his head and the excitement of secretly ordering his own muscle-pills found the horny 12 year-old so excited and hard, he had no understanding that his erection was so big that anyone would be shocked at its size. At 10 inches and 6 inches around, the young boy was enjoying the feeling of rubbing his hands along its thick hard and hot shaft as his mind pictured big muscles that would soon be his own and at that his enormous 12 year-old cock became stiff as a board and he felt a rush inside him that made him instinctively let go of it and open his eyes. As soon as he looked down at it the large rock hard young penis erupted into a spasm of cum that bolted out of his beautifully plump and circumcised head and gush out in streams of white thick liquid that splashed onto the bathroom mirror with a Thwapppp!! ThUDDDD!!! Thwapppp!! Dayton tried to stop it, as he reacted in horror at what was happening but he couldn’t, only getting more his cum mess on himself and the bathroom ceiling and walls as he panicked at his first orgasm.

The 12 year-old was glad his parents were out that day, as he knew he had a lot of cleaning up to do by the time he’d finished.

- - -

Dayton could hardly sleep a wink that night, tossing and turning with a constant erection he simply could not get rid of. Three visits to the bathroom hadn’t helped. Each time, after the horrific first orgasm had made such a mess, Dayton would climb into the shower and after closing the glass door – aim, however difficult it was, his erect penis at the drain. That was all it would take for him to then shoot wave after wave of cum at the shower floor while holding his breath that no one in the family would hear him.

The excited 12 year-old stared at his alarm clock.

3:45 am

He couldn’t even touch the pole that caused the tent of his bed-sheets, for fear of making a mess of his sheets and the thought of his brother sleeping in his bed with all those muscles kept re-entering the boy’s mind as he fought it to go away.

4:00 am

Dayton couldn’t take 1 minute more and got out of bed quietly and tip-toed down the hall and tried the door handle of his brother’s bedroom. Expecting it to be locked, the 12 year-old’s heard tripped into a rapid pace when it turned and the door opened with a creak. Dayton stopped suddenly and squeezed his eyes shut in hopes no one heard the sound and waited. After a moment of silence, he continued opening the door faster, in hopes it would be enough to stop the creaking sound and after managing to get the door open enough for him to enter, he slipped through the opening and tip-toed up to Dwayne’s sleeping form in his bed.

The 12 year-old’s penis was in full erection, and in full view after unbuttoning his pajama bottom’s crotch half way down the hall to let it out.

Standing over his muscled-up older brothers bed, Dayton tried to silence his breathing as his 10 inch cock throbbed. The 16 year-old muscle boy began to move in his bed and Dayton panicked but Dwayne stopped after adjusting himself onto his side, leaving his head directly below his younger brother’s erection. Dayton slowly and quietly lifted the sheet to look at Dwayne’s muscled body as he instinctively bent his knees and lowered his enormous cock down to the same level as Dwayne’s lips. Pre-cum was now leaking from his plump cock-head and a drip dropped onto Dwayne’s lips. The sleeping 16 year-old's tongue immediately appeared and cleaned the liquid from his mouth, as if an unconscious reaction. The muscle-boy’s face looked pleased by the taste as he continued licking his lips while sleeping, as if wanting more. Dayton looked at Dwayne’s muscle body under the sheet and lifted further to get a look at his brother’s legs when he heard Dayton begin to show signs of becoming restless.

Afraid he’d awaken, Dayton lowered the sheet back and began to tip-toe backwards in retreat as Dwayne began to move. Afraid of being caught, Dayton quickly reached the door and slipped back out and closed it and rushed back down the hall and into the bathroom.

It was 5:30 am by the time Dayton exited the bathroom and returned to his bed, having discovered new found pleasure in the fantasy of his older muscled brother sucking his cock in his sleep.

- - -

By the time the delivery truck pulled up in front of the house, Dayton was already outside with a pen ready to accept the package – in hopes his brother wouldn’t see what was happening. The 12 year-old found it difficult to hide his erection while signing for the package and could swear the delivery man saw it when he took the package – because the man seemed to hold it from him as he tried to take the box but his surprising strength had no issue with it and managed to yank it from the shocked man and return to the house, only to turn around to see him standing there stunned beside his delivery truck as Dayton closed the front door.

“Honey?” Dayton heard his mother call from the kitchen. “Who was that?”

“Nowbady mah… “ Dayton shouted back, escaping into his bedroom and closing the door. He wished he had a lock on it like his brother but had been told when he reached 15, he’d be allowed a lock on his door just like Dwayne. Dayton now wondered if it was because of puberty. He’d heard of it and now realized he was in it full-on but it simply wasn’t fair because he knew for a fact that his older brother hadn’t reached puberty until he was 15 and that was the reason now that he’d be denied a lock on his door.

Dayton frowned at the thought and ripped open the box to find a bottle full of capsules. His heart racing in his chest, Dayton ripped off the lid and shook out a handful of pills and looked at them.

Having the muscle-pills in-hand was enough to make the 12 year-old orgasm yet again, this time right into his pants at the same time he dumped the pills into his mouth and swallow them. It took a following 7 swallows before Dayton realized he should have taken them with water, since now the capsules seemed to be stuck in his throat. Uncaring that his crotch was wet from his orgasm, the 12 year-old yanked open his bedroom door and shot across the hall and into the bathroom. He twisted the faucet handle and leaned over, feeling the bathroom counter press into his cold moist pants and his spent cock as he lapped up gulp after gulp of cold water.

By the time he stood back up, Dayton felt a warm surge begin to swell from deep inside him and he instantly began feeling hot. The heat increased in magnitude at a rate that quickly made Dayton take off his shirt. The sight of his young 12 year-old body made Dayton quickly shut the bathroom door and lock it, unwilling to allow anyone to see what he’d hoped would soon happen.

Dayton’s eye-sight began to fade, causing him to panic as his breathing became heavy and his skin begin to sweat. His mouth became dry and as his vision grew dark, Dayton fumbled for the faucet again and he leaned back over to drink, but found that this time he seemed to have to lean and bend over much, much farther than before. Unable to see now, Dayton twisted the faucet and it seemed somehow to be smaller – much smaller in fact but he was simply too thirsty to give that any thought.

Dayton drank and drank and by the time he stood back up, his head rushed with blood and his knees buckled at the weight they felt. The 12 year-old fell to his knees with a thud that shook the house and Dayton felt the inside bend at his elbows incredibly tight and his back felt incredibly heavy and wide. He sat back up and felt such weight in his upper body, he lifted his arm to feel it and was met by enormous muscles. The thrill made his cock suddenly grow into an erection within seconds and slap against his pecs. Dayton squinted into the air as he then began to notice a blur of light, making him blink over and over hoping his sight would return.

Then a pounding at the bathroom door caused him to jump in surprise.

“Daytont!! Dayton!!” His mother called as she pounded on the door. “Are you alright!!? Did you fall??”

Dayton felt dizzy and unsure of what had just happened as his eyesight began to return. He stood up but was unable to find his bearings.

“Dayton… ‘bro yew awright in theyur??” Dwayne could be heard with his mother in the hall and at that Dayton opened the bathroom door with one hand to his throbbing head.

The door opened as his vision returned and he looked down to see his mother and brother with their eyes and mouths wide open. Then his mother suddenly became white as a sheet and then she became limp and fell backwards, into Dwayne. The 16 year-old reacted and held his mother up, while unable to look away as his face continued into distorted horror.

“WHOLLY SHIYUTT !!!” Dwayne exclaimed as he tried to make sense of what he was seeing.

“What?” Dayton said and just as he said it, he then noticed how deep and masculine his voice sounded, causing him to look down at himself and notice his new body.

12 year-old Dayton, now stood at 6’4” 300lbs of solid heavy muscle. His 24” inch arms swelled at his sides, with dark armpit hair frayed out hinting at the cracks beside his enormous bulbous pectorals that were now covered in a light dusting of dark body-hair that became thicker as it grew downward, into the cavernous crevasse that was his muscle cleavage. Dayton began to feel his new body with his huge hands and suddenly he noticed he had a stiff erection standing straight up at his mid-section that reached all the way up to his pecs. Dayton then bent over to look over his shelf of hairy pecs down at his legs and was met with the sight of hugely flared and hairy quads that led down to giant calves and the sight made his dick jump, throb and slap against his pecs with a "thwappp! thwappp! thwoppp!"


“Woah….” Datyon said in his new deep and sexy voice then looked back at his brother, still wide-eyed and open mouthed, holding his unconscious mother.

“Nayew Ahh got muscles!” Dayton shouted, his deep voice echoing through the house, causing his now smaller muscled older brother to tremble as he struggled to pull his mother backward down the hall, in an attempt to escape the muscle freak in front of him.

“Hahahha…” Dayton’s laughter boomed through the house as he stomped forward.

“Guess Ahh better find some’m to put on huh… utherways mom’ll wayke-up and just faynt agin.” The huge 12 year-old thundered. “Hahahha, just lewk ayt meyy!! Amm sherr BIG !!”

Dwayne stopped at the end of the hall with his unconscious mother limp in his arms, her feet on their heels at the floor missing a shoe. He then closed his mouth and took a dry swallow as Dayton stomped his way out of the bathroom and into the hall, then ducked into his bedroom.

“Ah’ll be raght back aywt, ‘bro…” Dayton thundered from inside his bedroom. “I wanna play muscle-flex with yew nawuh that Ay got muscles tew!! Hahahahh…”



End of Part 19

Another really interesting chapter, Kenstaff, again having to do with a younger brother stealing his older brother's Flexadrinizine and using it to make himself bigger and better than his brother, of course this time it's even more emphasized because of the young age of Dayton. I'm not against this, simply because I think you outlined really well in this chapter that it's about more about growing up, growing more mature, and experimenting, like many young teens and preteens do at that age.

<gurgle>

Wow.

I knew Dayton was going to be a potentially awesome subject to this experiment, from the moment he was introduced in this story! Kids are the same everywhere! And on an experiment going TOTALLY out of control, by the way.. !

Between Dayton and the still-to-be-revealed Matt, I think this game has just escalated into the highest levels, and is starting to literally crack the ceiling!

I had no idea Dayton was so "blessed" at his normal levels (lucky, lucky lad), and now, everything just got super-sized!!

One of my favorite memories (and from that day on, fantasies), was an obscure cartoon where this tiny little kid got a hold of a potion that suddenly turned him into this hulking, muscle-bound giant. The kid looked down at himself, blinked, and still being a kid mentally, suddenly turned to the guys that had been picking on him, looked 'WAY down at them and suddenly grinned wolfishly, and said,

"How 'bout it guys? Let's 'RASSLE!"

Oh.. shit.

That's GOTTA' be what Dwayne is feeling right now. Dayton is going to.. WRECK him beyond his wildest dreams, while the younger kid simply plays with his new toy brother.

And the kid still has the remainder of the bottle to gulp down. Knowing this kid's lust for muscle, and what he see in the mirror, how long do you think THAT'S going to last?


This forum is about the celebration of GROWTH and MUSCLE, and this story is doing that in spades!!


I think Chattanooga Tennessee better watch out. They are about to have an imposing new edifice in their town, in the shape of a mighty, gigantic, young Titan!

Or, putting it more bluntly, Mr. Z is in very deep kimchee!! He better pray to God on his knees that these boys don't join up, and seek him out for an endless supply of that stuff!

If that happens, then as mere mortals, God help us all!!


FANTASTIC CHAPTER, Kenstaff! They just keep getting bigger and bigger! (The chapters, I mean..)


Please Please Please Keep the story going!!

[powaqqatsi]

I'm really enjoying this series but wish you wouldn't write out the accent like that. It's distracting and slightly derogatory. Other than that, great work and I hope you keep writing - accent or not.

Can't wait for part 20!

Absolutely!!! I.m counting the seconds! I've been doing everything in my power to not pester about the next chapter, but I'm starting to look like a kid desperately needing to GO at this point...

Lots of holding my crotch and nervously hopping about..

If you're looking for a sign Kenstaff. THIS IS IT!!

I'm as hooked on this story as the kids are on Flexadrinazine.

[MuscleHintz]

Aww, Dayton is just adorable! And for someone so young to be so powerful, that's incredible!

I can't wait to see what happens next! Could Dayton perhaps become the biggest musclegod of this story?
