Mike walked into the gym and was ready to be admired. He couldn't help being noticed,

not with the body he had. At 18 years old, he had carved out a physique that would make

Hercules green with envy.

"Hey, bud," said Rob, the front desk clerk. "How big are those pythons these days?"

Mike grinned as he gave a quick flex of his powerful arms. "Just under 19, but always

growing," he replied. He went into the locker room and changed into his favorite workout

attire: a tight white T-shirt that left no ripple undetected, and a pair of thigh-hugging

cut off sweats.

As he emerged from the locker room and strutted to the free weights, all heads turned

in his direction. He knew they were in awe of someone so young who had gotten so BIG.

But Mike wanted to get bigger. And not just a little, but a lot. Ever since he first started

lifting for football, he knew it was size and strength he craved.

"Mike, think I could measure you before you work out?" asked Donny, a 16 year-old size

junkie who desperately wanted to get as big as Mike.

"Sure thing, Donny, you know how I love to find out how much I've grown." As Donny

readied the tape measure, Mike obliged with all the customary poses. He had a 50" chest,

18" neck, 19" arms, 32" waist, 29" thigh, and 19" calves.

"Damn, Mike, you get bigger every time you come in here," said Donny. "If you ever need

a training partner, you just give me a call."

"I'll keep that in mind, Don, but I prefer to work out alone." Mike liked to act somewhat

aloof at the gym, knowing that the mystery added to his attraction. And because of his

popularity, he was never at a loss to find someone to spot him from time to time.

Mike began doing his favorite lifts, and the intensity made him sweat profusely. Although

he was not allowed to work out with his shirt off, his sweat-drenched, skin-tight T-shirt

was just as good. Everyone in the gym could get an eyeful of his bulging muscles. At one

point during curls, his ever-growing biceps managed to slightly tear the sleeves of his shirt,

which no doubt sent some of his admirers into ecstasy.

After he finished, Mike headed to the showers, followed by some of the guys who had

stared at him lifting. He took off his shirt and his shorts and caught an eyeful of his hot

body in the mirror. "Big," he thought, "but not big enough." He began to rub his pecs with

his large callused hands, wishing they would grow into superhuman slabs of beef. He

flexed his right bicep and felt the rock-hard softball-sized muscle that sprung up; only

when it was three or four times larger would he be satisfied. He had to get huge!!

Mike wandered into the shower and began to lather up his monstrous physique. So hard

and so pumped from his workout, his muscles began to make him horny. He began to

fantasize about being a 350 pound muscleman instead of the 225 pounds he weighed now.

In his dream, he could bench press 600 pounds and squat 1000. So big that nobody could

resist him. Growing bigger, stronger, hotter every day!! This excitement was too much to

handle, so Mike began rubbing his cock, which had already sprung to life. He rubbed it up

and down as he dreamed about hulking out. After what seemed to be a only few seconds, he

shot his load all over the shower wall. He didn't even seem to notice the 10 other guys in

the shower watching him get off on himself and fantasizing right along with him.

When finished showering, Mike grabbed a towel and headed back to his locker. He put on

his snug tank top and shorts, gazed at his hot body one more time, and went back to the

main workout area. Feeling pumped from his hot jackoff session, he went to the chin-up

stand and hopped up on the bar. He started doing chin-ups, grunting really loudly so all the

other guys would hear. One, two, three eventually turned into ten, twenty, thirty, and Mike

could feel his arms GROWING!! His veins came alive and began snaking across his arms as

they were gorged with blood. The muscles were bulging under his skin, burning with every

rep. After fifty, he let go and landed on the floor. "Donny, bring that tape measure over

here!" he barked.

In a flash, Donny was by his side. Mike reached up and flexed his double-peaked right

bicep, which was burning with power. Donny carefully put the tape around it and cried

out "20 inches!" Mike, knowing that the whole gym was watching, focused all his power

into that right bicep and squeezed it as high as it would go. As he knew it would, the

muscle sprang to life like something out of the Incredible Hulk. As it bulged, it easily

snapped Donny's tape, and Mike added, "looks more like 21!"

Donny stared open-mouthed at the bulging bicep, and a wet spot began to form in his

workout shorts. Mike grinned and headed out into the parking lot.

The next day, Mike jogged down to the high school to talk to his football coach about

the upcoming season. Although it was summer vacation, he knew the coach would be

there working on some new plays, and as the star quarterback, he wanted to be the

first to try them out. Plus, this way the coach would get to see the progress he had

made on growing his muscles.

Mike was walking through the locker room when he heard the coach talking. "So you think

you have what it takes to be our quarterback, huh?" Mike froze in his tracks. Someone was

trying to muscle in on his position. How could any guy expect to be a better quarterback?

Mike walked up behind the locker nearest to the coach's office and peered through the

office window. The coach was looking over the new player, but Mike couldn't see the guy's

body because a filing cabinet was blocking his view. "Are you telling me somebody else has

guns like these?" said the player. He pulled up his shirt, tossed it on the ground, and hit a

pose. "23 inches, all muscle!"

The coach's eyes grew wide as he took in the kid's biceps. Mike desperately wanted to

see if his claims were true, but he didn't dare bust in now. "Let's go up to the weight

room and check your strength with those arms," said the coach. He left the office and

headed toward the gym, with the kid following.

Mike could not believe what he saw when the kid came out of the office. He had to be

at least 6'4", probably 260 or 270 pounds of muscle. He had short blond hair, blue eyes,

and a deep tan across his torso. He had the same basic blocky shape that Mike did, but

his muscles all bulged a little bigger and looked a lot harder. He was the muscular ideal

Mike wanted to be.

He followed the two up to the weight room and secretly watched the stud lift. He could

easily outdo Mike on every single lift, a fact which made Mike very horny. When he did

chin-ups, he didn't have to stop at 50, but rather went to 80. He could do pushups by

the hundreds. His bench press weight was a new school record. And by the time his

massive thighs ripped open the seams of his shorts from doing several sets of punishing

squats, Mike had cum all over his shorts.

Afterwards, the kid went outside and tossed the ball to the coach. As expected, he could

pass, kick and punt farther than anyone else on the team. Mike knew his days as quarterback were numbered with this guy on the team, unless he got a lot bigger real fast. He cleaned himself up and headed back for home.

On the way, Mike took a side trip to a Pro Body, a small health food store, to check out

the supplements. He figured it couldn't hurt to see what was new on the market. Upon

entering, he walked over to the weight gain powders and started checking out the

canisters. After a few minutes of browsing, he heard a voice behind him say, "Looking to

get BIG?"

Mike spun around and faced the store clerk. He was a short, scrawny guy who looked to

be in his mid-twenties, but obviously was turned on by Mike's size. His nametag said his

name was Andy. "Yeah" Mike replied, "I need something that works well and works fast.

I'm looking to make some massive gains."

"Well, you already look pretty big to me. But if you want something a little on the extreme

side, you're looking in the wrong place."

"Nah, not the juice. I don't go for that crap."

"No, not steroids," answered Andy. "What I meant was, we keep the really good stuff in

the back. Experimental weight gain powders I hand out only to special customers. Like you."

"What have you got?" Mike asked as he began flexing his pecs.

"Let me show you," he said as he dashed off into the back room. Andy couldn't believe

his luck. All his life he dreamed of creating a magic muscle potion that would turn himself

into a muscle god, and now after years of working on his formula, he had found the

perfect candidate on which to test it. "If this guy grows bigger, I'll try it on myself next,"

he thought. Andy took a small vial of white powder out of his pocket and carefully poured

it into a can of Monster Mass Formula. He stirred the contents and then replaced the lid.

"OK, here we go," he said as he walked back to Mike. "This stuff is experimental, but it

should really pack the beef on a motivated lifter. There's only two things I have to

mention: one is that it works with the food you eat. This stuff should amplify the vitamin

and mineral content of your food, sending it straight to your muscles. So the more calories

you ingest, the stronger you'll get and the more you're gonna grow. And second, your body

will most likely permanently adapt to the chemicals in the powder after about a month, so

it's only gonna work for that long. After you've been on it for 30 days, it probably won't

work any more."

Mike stared at the can. "No problem about taking in more calories. I can eat anything I

want, and my muscles can burn it off," he thought. "And I've only got a month before

football practice starts anyway, so this is perfect." He looked back at the clerk and

asked, "How much is it gonna be?"

"No charge. Our little secret. Just come back in a month and let me see the results,"

Andy replied.

"Almost too good to be true! How big do you think I can get?"

"That's part of why I'm testing it. Nobody has put any limits on it yet."

"Well, for free, I guess it can't hurt. Thanks, man. I'll see you in a month." Mike turned

and headed out the door. He couldn't wait to get home to mix up a batch.

After arriving home, Mike quickly made himself a ham sandwich, and then mixed up some

of his new formula in a tall glass of milk. Almost immediately after his meal, he could feel

a new sensation in his body. A certain tingling that hadn't been there before. Was it the

formula? Was he nervous about growing bigger? Or was he just still hungry?
