Sibling Rivalry

added 14 years ago BM S

"Little fucking bastard..." Cole grunted while he continued his workout. He was a pretty
good looking guy -- he was short, only about five feet and two inches tall, but he had a
muscular build to try to compensate. He didn't look like a bodybuilder, but he was still a
little muscular -- just more on the stocky side. "Why did my little brother get lucky with
the genetics?"

He continued to grunt out the words angrily until he was finally finished his workout. You
see, while Cole was a good looking and handsome man, he was incredibly jealous of his
older brother, Matt.

Matt was only two inches taller than Cole, but out of sibling rivalry he always rubbed it in.
His build was much more lean than Cole's was, but his muscles were much more defined
and better looking.

The two of them had been fighting since birth. Cole was two years older and 24, while
Matt was 22. Cole desperately wanted to be the alpha male -- but his brother always took
over the position and humiliated him.

After his workout and a shower, Cole decided to take a walk. He was having a bad day --
no matter how much he worked out, he still couldn't get that buff.

The sidewalks were relatively crowded but Cole didn't have any problem getting around --
he'd just shove his way through when he was in a mood like this.

He suddenly saw the picture of a hugely muscular man -- he must have been a
bodybuilder. Cole was always in denial about being gay, but he was, and he loved muscle
very much. When he approached the poster, there was a strange packet taped to it with a
pill inside. What was that there for?

Of course, Cole took the packet anyway. Curiosity got the best of him, and he was in such
a foul mood that he'd do nearly anything at the moment. Deciding that walking was
boring him, he began to walk back to his apartment. Unfortunately because of recent
financial issues, Cole and Matt were roommates.

"Gr... I have to get even bigger than him... can't get lazy..." Matt grunted while he lifted
weights. While he knew he was bigger, stronger and taller than his older brother, he didn't
want to risk losing that precious advantage -- he loved being the alpha male, after all.

After finishing his workout, showering, he decided to head back to his apartment. He
wanted to watch the baseball game today, and certainly didn't want to miss it.

On his way home, he was distracted by a poster. It was a poster of a freakishly huge
muscular man flexing. Matt tried not to stare, but he couldn't help himself. He wished he
could be like that guy.

Unable to stop himself, he walked closer to the sign to get a better look at the guy. Oddly
enough, there was a packet taped to the sign with a pill in it. Matt was a believer in
'everything happens for a reason', so he decided to take the packet and head home. He'd
try to see what it was later.

When Matt got home, he noticed that his brother was sitting on the couch and watching a
football game he had tivo'd. "Put it on the game." Matt said in a bossy tone.

Cole was surprised to see his brother enter, and even more surprised to hear him
command him to change the channel. While that wasn't unusual behavior, it always pissed
him off. "Fuck you, man. I'm watching the game."

"We're going to watch baseball. It's much better than this junk!" Matt said angrily.

"Well, I've got the remote so too bad for you." Cole said, smirking.

Matt immediately lunged at Cole, trying to grab at the remote. He wasn't exactly polite or
subtle, and he knew he was stronger than his brother.

Cole expected it so tried to roll off the couch to dodge Matt's pounce.

The two of them went at it for a while -- ripping the remote out of each other's hands and
trying to change the channel, only to have the other brother grab it back again. Eventually
they were trying to put each other in headlocks.

"You weak little piece of shit!" Matt said, having his brother in a headlock.

Cole growled and tried to get out of it, but he was sort of stuck. He wasn't going to give up
that easily, though. Instead, he pulled Matt backwards, slamming him into the television
as hard as he could.

The television fell off of the stand and broke -- the screen shattered, and all that was
within seemed quite squashed.

"What the fuck did you do that for!?" Matt screamed, furious.

"You were the one who fell on it, fat ass!" Cole retorted.

"I... I can't stand you! You're such a weak piece of crap! I can't believe you're even my
brother!" Matt screamed, storming off to his room in a rage.

Cole wasn't hurt by the words -- in fact they just made him angrier. He too stormed off to
his room and lied down on his bed. He wished that he could be much bigger than his
brother, but that didn't seem like it was possible. How was he going to go through life like
this?

He looked over to his bedside table, seeing the packet with the pill in it. He had no idea
what it would do, but at this point he was desperate for anything. Maybe it would drive
him into a homicidal frenzy and cause him to kill Matt -- who knew what would happen.

He opened the packet and dry swallowed the pill. At first, nothing happened. He figured it
was some sort of practical joke someone had played... it most likely was a sugar pill, or
something.

After a few minutes that changed.

He suddenly got a very uncomfortable, raging hard on. It was out of no where -- in his
current mood he wouldn't be turned on so randomly, so what the hell did it? Did he take
viagra or something?

Well, he realized that maybe jacking off would do him some good. Not only did he feel
incredibly horny, but he figured that if he masturbated it'd help him relax and calm down.

He adjusted his package through his jeans -- geez, getting a boner this big was quite
uncomfortable when wearing jeans!

The second he touched it, sparks of immense pleasure shot up through his body. It was as
if he just ejaculated -- but he didn't! His cock was still hard, and he just lightly touched it
through his pants.

Cole was too horny to even worry about his jeans at the moment. Reaching down with a
hand, he began to massage and rub at his crotch through his pants. It felt so good... his
cock felt bigger than ever -- he couldn't believe it.

It didn't take long for him to have an orgasm. He felt his cock spurt multiple times, and an
obvious wet spot was forming in the groin of his pants. He wasn't embarrassed by it -- in
fact, he thought it was hot!

Then something else happened. Something very out of the blue. Cole began to feel his
body tingle all over -- it felt good, but very strange and foreign to him.

After a while he felt his clothing get a little tighter. Maybe he was just having trouble
breathing after having an orgasm that amazing? He wasn't sure...

Once again his doubts were proven wrong. The tingling began to increase, and his
clothing felt even tighter now.

In reality, Cole's entire body was growing more muscular. His legs, his arms, his chest, his
neck, and even his cock were all growing now.

The once slightly baggy shirt he had on was now quite tight. His nipples were completely
erect, and visible through his shirt. The sleeves of his shirt were having a little bit of
trouble containing his much larger biceps, too. His chest was actually sticking out now,
visible through the shirt.

His jeans were also much tighter. While they weren't too baggy before, now they were
quite tight. His legs had grown quite a bit and were bulging out now -- his cock wasn't
helping out, either. Before it was an average 6 inches erect, but now it had to have been 7
inches.

"Holy fuck..." Cole said, running his hands over his stomach, feeling his defined, hard,
sexy muscles. Unlike his brother, he was a little hairy, but he still felt incredibly hot.

He thought he was hallucinating until he looked down and into a mirror to see that his
cock was visibly bigger -- one couldn't fake that too well, after all! He just realized
something, though; he was still horny.

Even if he was unaware how the changes occurred, he didn't care, he had to jack off again.
Seeing his sexy body was enough to make him practically cum, but he figured he'd put in
a little more effort now. Unzipping his fly and letting his shaft pop out, he began to stroke
it.

Once again, it only took a few minutes for him to blow his load -- this time it actually his
the ceiling on the first spurt, then his shirt, and another big spurt onto the floor.

It was happening again. The tingling sensation came back, faster this time, and he could
feel his body expanding.

His already impressive chest filled out his shirt even more now to the point where it
looked like it was painted on. His arms were so big that if he flexed them the sleeves of
his shirt would surely rip.

He had to take the belt off of his jeans and undo the top part of them because his legs
were getting so tremendously large, as was his cock.

Once again, his cock gained another inch or so -- eight inches now. It was also getting
quite thick. It never was soft, for some reason... always erect, always ready.

Cole had gained at least three inches in height already, and a ton of muscle. He now knew
what made this happened, too.

Whatever was in that pill caused him to grow every time he blew a load.

He was too excited to jack off more; he wanted to show his brother his new size and cock
-- maybe he'd even get his little brother to help him out?

"Hey, Matt, can you come here for a sec?" Cole didn't realize it earlier but even his voice
was deeper, manlier, and much sexier. He began to stroke his cock lazily with one meaty
hand as he awaited his brother's arrival.
