By Shade

The feeling hit him like a ton of bricks. He needed a hit. He needed it bad.

Zack’s indomitable will had never been overwhelmed by any substance that he’d ever tried before in his life. But the blue serum just called to him.

The day after the first hit, he’d awoken feeling refreshed and alive. The after effects still lingered inside him almost eight hours after the stuff had hit his bloodstream. It was amazing. Even more amazing was the physical change it produced in his body. From the first time it hit the blood, Zack’s strength increased immensely. He’d recognized that from the first. But over the past week, he’d noticed that with each hit that exceptional strength was growing exponentially. Maybe that had something to do with the other dramatic physical changes the blue serum was doing to him.

That first night at the gym, Zack had moved enough iron to do a seasoned powerlifter credit. Made all the more remarkable by the fact that he weighed only one hundred fifty pounds the morning Derrick delivered the stuff to him. With that came the discovery that the blast of primal super strength lasted about three hours from when he took a hit. The pleasant side effect was that during that time and for some time afterwards his body responded to his exertions by building more muscle to compensate at an accelerated rate. When the flare of strength passed, his new muscles were still able to handle loads his pre-serum body wouldn’t have dreamt possible. The next day the scale said fifteen new pounds of muscle graced his frame. It was hypnotic.

Not that Zack had ever wanted any of this of course.

But he couldn’t help it. He couldn’t stop it. He didn’t want to. He’d discovered that he liked it too much.

Then the cravings had come. A day and a half after his first injection, he could feel that he was returning to normal. The emptiness of his life was still there waiting for him. He needed that feeling again badly. He recognized it for what it was, but he felt it was a small price to pay on balance.

He had taken the stuff three times now. Each time going to the gym to test his mettle. As the juice left his system again each time the cravings eventually returned. Each time seeming to come faster than the time before. And with the third injection he found that he’d finally finished the first vial. There were only four vials remaining of the original case he’d purchased from Derrick.

But the feeling had come on him again just now intensely. He couldn’t resist and so he had taken a fourth injection. The first from the second vial.

As the wave of power crept over him, he sank back into the chair to revel in the ecstasy of his own masculine vitality. He thought about going to the gym again. He hadn’t gone back to the same one twice, lest one of the regulars members got suspicious. Then he remembered that this was Saturday. He remembered that one of the guys at the gym he went to the last time had told him about an arm wrestling contest. His name had been Joe something.

“You’d be great,” Joe had sighed watching Zack curl the weight. “Look at your arms they’re amazing.”

Zack had grunted. Joe was pretty amazing himself. Not as big as the bodybuilder Matt that Zack had met on the first night of this odyssey. Joe was shorter than Matt, but he had a denseness to his muscle that made him look stocky. His arms were ropes of muscle. When he curled those guns swelled into round balls of power. Nineteen or twenty inches around at least Zack suspected. Zack had no idea of the size of his own arms at the time. They were growing even as he curled the weight. But he figured they were catching up with Joe’s. Eventually maybe even with Matt’s titanic arms too. Unlike Matt though, Joe hadn’t asked Zack to bed. But his praise nevertheless turned Zack on.

Later when he’d got home that night he’d measured himself. His arms were just shy of sixteen-inch balls. And they felt as hard as steel to him. His chest after three workouts had swollen to forty-five inches cold, and his thighs were at twenty even. Looking at himself that night standing naked in the mirror he saw a robust young jock staring back at him. He wouldn’t even have recognized himself if he hadn’t lived through the changes. Even his face was different, he thought. His handsome features now had a glow of happiness and health he’d never known before. He grinned back at himself stupidly unable to help himself. Even his cock was responsive to the serum. Before, like every other thing in his life, sex had been something he’d endured to try and find meaning and purpose. He’d tried women, he’d tried men and he’d tried masturbation. Nothing had held his interest before this serum. But standing looking at himself in the mirror he was getting off on his own body. His normal cock had grown by at least a couple inches. And that night he’d jerked himself off in the mirror until his cum sprayed all over the bathroom floor.

But that was all in the past and this was now. The serum entered his system like it had three times before. The initial effects passed and once he was able to think clearly again, he dropped the empty syringe into the wastebasket. He hadn’t given that contest too much thought at the time, but it seemed better than just going to the gym again. A chance to test himself against other human beings. The contest was being held out in the valley past the hills. Not much out there in the way of civilization and maybe that was why it proved such a popular spot for gatherings of that nature. He stepped onto the scales and noticed that he now stood at about one hundred ninety-five pounds. He suspected also that he grown too; because his pants didn’t seem to fit right anymore either. They were too short. But that was fine by him. Shopping no longer seemed like such a mundane chore to him. Zack didn’t mind if people checked him out. It appealed to an ego stoked by the serum.

So he grabbed some old shorts and a t-shirt. The t-shirt had once been too large for him. And it hung loosely over his chest even now. It was a gift sent from his parents after one of their many trips. At the time he’d been disgusted they didn’t know him well enough to even get close to the right size. Now it made him laugh. The shorts though went on with a little more effort. His thighs had been much smaller when he’d gotten them. Now they fit snug. The squats he’d done the other night had caused his ass to fill out. The muscles of his glutes had become higher and more rounded. He sighed with pleasure. This outfit would do. As an afterthought he’d made up another syringe too and put it in the glove compartment. It would take him an hour to drive to the valley – he might need a pick-me-up for later.

Wow, he thought to himself, he’d never taken a hit two days in a row, much less on the same day. What would that do? He felt a pang of excitement as he decided it would be cool to find out.

The drive was nice. The air was losing the summer heat as the calendar had moved into fall. Still it was going to be a warm day out there.

When he got to the field where the contest was located he parked off to the one side. The place was filled with people of all descriptions. A pretty rough looking crowd all in all though. There were no smooth polished city folks in evidence. Zack looked at his car. It was a sports car, but it was the kind that lawyers drove. Maybe it was time to turn it in for something else. A little something more primitive maybe?

He noticed a registration tent, so he walked over.

“Weight?” the guy asked.

“One ninety-five,” said Zack smoothly, putting down his money for the fee.

“Okay,” he said, “You make it into class one then. Just barely. Those are the big guys.” He eyed Zack’s arms wearily. “Since you are right on the line I can put you in class two if you want.”

“Nope,” said Zack feeling confident, “Class one is fine. What are the rules?” He filled out the registration form the guy handed to him.

“Single elimination, strongest wins,” said the guy, “No other rules. We aren’t part of any federation here. These guys do this cause they like the competition. Whoever brings the other guy’s arm down first wins. Period. Got any problems with that?”

“Nope,” said Zack.

“All right then. Contestants in their class are matched together at random. Go to table five. Whoever wins will be instructed on what to do next. Good luck.”

Zack nodded at him and left. His competitor was waiting for him at the aforementioned table. He was a big guy, just a little smaller than Joe. He had no shirt on, and while his body fat was high compared to most others there, he looked like he was packing some respectable muscle on his frame underneath it. His arms were big and thick like a guy who worked swinging a hammer against concrete all day long. But it didn’t necessarily look like he worked out. He looked at Zack and snorted. Then set his beer on the table.

“You ready to go?” he asked Zack sneeringly, “Cause my next opponent’s waiting for me.”

“Bring it on,” said Zack sitting down across from the other guy, “Don’t want to have to make anyone wait for me.”

They immediately locked fists and braced themselves. Zack hadn’t arm wrestled in his life so he wasn’t sure what to expect. The guy across from him was anticipating an easy victory and he put his hammer down and used his power to muscle Zack’s arm toward the tabletop. Zack was caught completely off guard, partly by the guy’s vise-like grip.

His arm got to three inches from the table before he realized he was about to be eliminated entirely on the first go round.

“No fucking way,” he snarled at the bigger man. His arm stopped cold as a blast of strength ran through him. No overfed muscle wannabe was going to crush him so easily. At first he responded with all his power and nothing happened. His arm stayed where it was. Then he felt the real power take hold. Suddenly the guy’s arm seemed like nothing to him. Just dead weight. With ease he brought the other man’s arm up slowly. A small crowd had gathered to watch and a few began to cheer him on. Inch by inch the other man’s arm came up until they were even. The look of surprise on the fat man’s face turned into a look of fear when he realized Zack was going to take him down. It was inevitable. Zack’s muscle was as hard as bedrock. His forearms looked like steel cords. The bicep on his right arm had swelled noticeably against the shirtsleeve. Then it was over. When he stood up in victory he was aware that his shirt felt tighter.

He moved through the next thirty competitors in his class, bringing them down just like he’d brought down the muscle wannabe at table five. He found he didn’t even have to move, they just kept bringing guys to him. He was careful to toy with them. The play was amusing. To first let each opponent think they were in control, and when they least expected it to turn on the muscle power and bring their dreams of the championship to an end.

By the time he’d finished with the last guy he was informed that he was in the championship playoff for class one. The next two guys were much harder competition. Even with his super strength they were powerful. The last one actually gave him a real fight and for a moment he didn’t know if he was going to be able to summon the strength to bring him down. His arm felt tired. Then he realized glancing at a watch that four hours had past. His super strength had failed him over an hour ago. Wow! He’d brought down those last two guys all on his own ability. He looked at the next table where two men were still fighting to see who Zack’s final challenger would be. Both of the guys were big, but one was tougher and meaner looking than the other.

Absentmindedly Zack pulled at the collar of his shirt. Unaware of how uncomfortably tight it had gotten.

He thought fleetingly of the other syringe in his car, but there was no time to go and get it. This competition didn’t stop until there was a winner. A big crowd had gathered as the tough man blew past his competition. He was all that was standing between Zack and the trophy. And as Zack was informed, this guy had won for three years running.

But Zack still felt powerful. Still confident. He looked the guy over again and decided he wasn’t near as big as he had looked earlier.

After a minute he sat down at the champions table and locked his arm with the reigning man. The other guy tried to crush Zack’s hand in his grip immediately, but Zack gave him every bit as good as he got. Maybe that was a glimmer of pain he saw in the other guy’s eyes? Whatever it was it was gone in an instant.

“Say when,” said the other guy. Zack responded with a confident “Go.”

Zack gritted his teeth as they began to get on with it. He felt his arm swelling with size and power even as they began. The challenge of it made pure adrenaline run through his veins, which mixed with the remaining serum. It increased his sense of power unimaginably. He was going to smash this guy’s hand down into the table. The other guy didn’t look intimidated at all. Zack figured they were well matched and his lip curled in defiance.

Their muscles tensed. Zack wanted to show him just what real strength meant. But soon he found himself pushing harder and harder just to keep him from pushing his hand down toward the desk. It wasn’t long before he was pushing with all his force. The other guy just smirked at him and didn't seem to be struggling at all.

“What’s the matter?” he asked, “This muscle too much for you?”

“Fuck you,” growled Zack.

The steel grip of the other man got even tighter. Zack thought for a minute he might give in to the pain. He’d never felt pain like that before. But something inside him said no. He liked it. The pain made him feel even more alive. He focused on using the pain to tap into his own strength, and then he unbelievably squeezed the other man’s hand right back.

This time there was a grimace on the face of the other man. They both leaned forward across the table – their noses almost touching. A trickle of sweat ran down the side of Zack’s face. But across from him the other guy had sweat beading up on his upper lip and forehead.

Then they were both back at it, even harder than ever. Zack’s arm felt bloated and tight from the tension, but it had never felt so powerful even when in command of all that extra strength that a hit of the serum always gave him. Even though the other guy was matching him, he felt like he could take on the world – take on anything. They leaned into each other so closely that their shoulders were almost touching,

Zack wanted to take everything this guy could throw at him. His face was now drenched with sweat, and it was dripping down onto the table. The other guy’s sweat still only beading on his upper lip and forehead, but a vein had popped out of his forehead near his temple. It looked to be throbbing.

Each man had no idea how long they were locked together. And the crowd watched in amazed awe. Someone would later tell Zack that it had been over a half hour. The contest went back and forth, back and forth. Sometimes one man had the advantage and then it would switch as the other found a hidden reserve of strength. By now both men were drenched in sweat, their faces and arms colored violently with strain. Muscles pumped. The other guy’s arm had at first looked more muscular, as big as another man’s thigh. But Zack’s arm muscles were popping out like steel balls. Neither man would quit. They were nose to nose now. Each stared into the other’s eyes, trying to psych the other one out.

Suddenly, with a burst of power the other man pushed down hard on Zack’s arm, and brought Zack’s hand to within a fraction of an inch off the desktop. But Zack was not that easy to pin.

He let out a howl of anger and frustration. The crowd gasped aloud. Excited murmurs ran through the throng.

“I will fuckin destroy you,” screamed Zack. Never had he been challenged like this in his whole life and he didn’t like it.

He pushed against the other man with all his might. And then it happened. A surge of power ran through him. It roared up from somewhere deep inside. His strength increased just as if he’d taken a hit of the serum. Like before the pressure of the other guy’s arm felt like nothing to him.

With ease he now held the other man’s arm. Then he smiled at him.

The crowd watched in breathless anticipation. Then they heard the seam on Zack’s shirt give way. Each string of the cotton shirt popping as it ripped up the length of his arm. His powerful bicep appeared completely bare. It was a massive mound of corded steel, big and round and full. It seemed to have swelled from the pump until it was twice and again far bigger than the arm of the man sitting across from him.

Zack took a deep breath and felt himself flex involuntarily. Shaking with power. He was hard. His muscles were pumped. His inflamed chest and back muscles suddenly filled his already too tight t-shirt. It looked like an explosion to the crowd. The shirt couldn’t take it. Pieces of cotton cloth flew everywhere around him. Even his shorts ripped a little up the seams as his thighs increased.

Zack felt so strong that he could have taken on an army, let alone this lame man sitting across from him. He began to crush down on the other man’s hand with his thick fingers; just enough to make him visibly wince in front of the crowd. Zack was totally in charge now, and he knew it, and now the other man knew it too. He could sense the change and so the other man put his left hand over his right, and pushed against Zack desperate to bring Zack down. But Zack held his hand still an inch from the tabletop. He laughed deeply now. He was jacked. He became turned on by his new strength.

Slowly he began to push up against the other man’s two arms. He was barely straining, and the other man’s arms moved upward, slowly and steadily, despite the fact that he was leaning his whole weight onto Zack’s hand now.

The crowd roared as they knew a new champion was about to appear before them.

“What do you think now?” asked Zack, and he pushed the other man’s arm up to the starting position, and then down toward the tabletop.

The other man was totally dumbfounded as his remaining strength faltered. No man had ever pinned him in arm wrestling. But he had no time to ponder as Zack slammed his hands down onto the table with an audible thump. And he pinned them there too. Just hard enough to hurt. Then he lifted them up and slammed them again just to be sure.

It was amazing. He let the man go so he could stand up and raise his huge arm into a victory flex. He squeezed the bicep of his winning arm tight, and it rose and rose, full and huge.

Zack stared at his own arm, his eyes glazing over as he relished his new power.

“Fuck yeah!” he cried out to the crowd, and they responded in kind.

The other man was defeated. He slumped, astonished. The rush of the cheering was too much in Zack’s ears. Suddenly someone was giving him a trophy. Then there was a woman posing at his side while some other man took a picture of them. He was deaf to it all. Still dazed. Absorbed in his own power.

He walked away from the crowd, trying to get some air. When he reached the edge where the tents were he heard a voice behind him.

“Zack?” it asked him.

He turned around and there was Matt from the other night. Only instead of looking up at him, Zack realized they were now looking at each other eye to eye.

Matt looked him in the eye and said, “It is you Zack. I thought it was. But how…?”

Zack smiled at him and said, “Hey there big guy. I’ve missed you….” •
