Taking on the Big Dog
🕑 Added 2021-03-26 16:51:58 +0000 UTCAaron could not believe what he stumbled onto at the gym: an actual strength challenge between two of the biggest bulls there. He had finished his time on the treadmill and had taken a seat on a bench near the free weight area to rest when two muscleheads walked by: a dark-haired man named Max, and a blond named Hoyt.
The studs had been friends since they met in high school ten years earlier. They both were around 6’3 and between 280 and 300 pounds – Max was a little taller and leaner, and Hoyt was a little shorter and heftier. And sometimes, when jacked up on pre-workout and supplements (plus all their natural testosterone), they would compete to see which of them was the strongest.
This time it was Max who started the taunting with a crack about Hoyt’s smaller quads, and Hoyt responded with some good-natured ribbing about how his arms were bigger. A few minutes later the joking escalated into a friendly argument, and then soon they decided to settle the fight with an intense full-body workout involving 15 different lifts.
“And what does the winner get?” asked Max.
Hoyt looked around and spotted Aaron on the nearby bench. The cute little man in the too-big tank top was around 5’6 and maybe 100 pounds, with short brown hair and soft brown eyes. He had been keenly listening to everything the bigger man were saying, and his dick was tenting up through his shorts.
“How about the winner gets to have some fun with our audience over there?” asked Hoyt. “I think he would happy to spend some time with either one of us.”
Max agreed and shot a quick smile over to Aaron, who smiled back at the thought of being the prize in this competition.
The big men went over the rules – they would lift the exact same amount of weight on each exercise, and who ever could do the most amount of total reps without cheating would be the winner. They shook hands, and then started loading up their bars and pumping an incredible amount of iron, which caused their muscles to fill with blood and surge in size.
"I would love to be that big!" thought Aaron to himself. He flexed his left bicep and looked at the tiny muscle, and then started flexing it harder and harder to see if it would grow. But try as he might, his arm remained small and puny-looking. Hoyt caught sight of the display, laughed, and pointed it out to Max.
Before Aaron could feel too sorry for himself, however, Hoyt came over and ordered him to serve as his spotter while he was bench pressing. Aaron leaned over and watched the stud pump out rep after rep of the insane poundage, and then made sure the bar was properly re-racked when he was done.
Hoyt stood up and was dripping with sweat, and Aaron couldn't help but get aroused by the manly odor. The bigger man then took off his shirt to reveal his bloated torso, and then tossed it over to Aaron. "I know a puny guy like you couldn't possibly handle that kind of weight by yourself, but at least you can hold my shirt, right?"
Patrick nodded, took his seat back on the bench, and played with his erection as he took in another whiff from the shirt.
Finally after almost two hours of intense lifting, Hoyt ended up beating Max by a total of three reps. The defeated man took the loss in stride, thanked his friend for pushing him so hard, and vowed to make a comeback: "I'm going to have my lover fix me nothing but red meat for the next week, Hoyt, and next time you're going down."
Hoyt laughed and replied, "Keep dreaming, little Max. You'll never top the Big Dog."
Max then headed for the shower, and Hoyt turned to look at Aaron, who had stood up from the bench after the competition. The Big Dog walked up to him and put his huge, sweaty muscle gut right up against Aaron's shirt. "I'm feelin' so virile and manly today, Puny. That workout made me feel like a fuckin' stud!"
Patrick stared at Hoyt's outrageously huge upper body and took a deep whiff of Hoyt's musky odor.
"Ever seen an arm that big, little guy?"
Aaron just shook his head to answer.
Hoyt then flexed his left arm and put his bicep right in Aaron's face. "Look at the size of this motherfucker, Puny! That is a fuckin' man's bicep – 24 inches cold...and growing every day."
Aaron put his hand on the Big Dog's hard bicep. He tried to squeeze the muscle, but Hoyt's arm was just too strong and it wouldn't budge.
"That's it, little guy, feel the results of my hard work. Bet you never had a workout like mine, right? You probably do your Jazzercise or jogging and tell everyone it's because you just want to 'tone up,' but secretly you want to pump the big weights like me, right? You would kill to be a real muscleman, right? But instead of giving you tons of muscle and strength like I got, God decided to give you weakness and frailty and delicateness, right?"
Aaron nodded meekly.
"Yeah, he gave me these great big pythons and he gave you toothpicks. It's just not a fair world for someone like you, is it? I mean, you can take all the pills and protein powders and supplements and vitamins, and work out every day for a year and gain maybe two or three pounds of muscle, while I gain that from just a couple of lifting sessions here with Max.
Hoyt unflexed his arm and reached down to grab his crotch. "But I tell you what, Puny. I'm gonna try to help you out a bit, OK? Would you like me to help you?"
Aaron nodded again meekly.
Hoyt smiled. "Good! I'm going to help you by letting you suck some of the protein out of me...special protein that will help you grow.”
Hoyt knew his cum was different than other guys. It somehow not only made it easier for him to get big and strong, but when ingested by others, they would get a temporary muscle increase as well. Usually it was only 5 or 10 pounds of muscle, but sometimes it was as much as 25 or 30, but it was enough to toughen up his lovers so they could keep up with him in bed. Hoyt loved to be dominating and aggressive in the bedroom, but he didn't want to permanently damage his conquests during their lovemaking, so would have them suck him off first so they could improve their strength and stamina.
And no matter what was taken from him, the change was always temporary – the guys would revert to their former slightness within an hour or two. And more importantly, Big Dog was never affected – the receiver of the cum would grow, but he always stayed the same size.
The two men decided to skip the shower and instead hopped into Hoyt’s truck for a short drive back to his house. Within a minute after arriving, they were on the bed completely undressed. The big man laid his head on the pillows and the smaller man took his position closer to the foot of the bed.
Hoyt closed his eyes and enjoyed how Aaron was working on him down there. “That little man can suck. He’s so much better than the others. He’s so much more intense.”
He tried to form other thoughts, but became lost in the euphoria.
Aaron was definitely going to town on Hoyt’s cock. He loved to give blowjobs, and he loved big musclemen, so he was in heaven. But as he licked and suck the 10-inch cock in front of his face and gazed upon Hoyt’s mighty physique, Aaron also repeated his wish from when he was on the bench at the gym: “I would love to be that big!”
Everything Hoyt had said to him had been true: it wasn’t a fair world, and God gave some men pythons but had given him toothpicks. Aaron desperately wanted to be a muscle stud, but he could never put on the weight. But that all changed with Hoyt’s cock erupted and the magic cum rushed past Aaron’s lips and down his throat.
As it entered his body, Aaron continued to suck and suck and suck. He didn’t want to miss a drop. As he did so, he could feel his body changing.
It started in his chest. It was getting bigger, wider, and fuller, and his nipples grew hard as the beef piled on. Then he felt more muscle streaming into his arms, growing his biceps and triceps into those worthy of the Big Dog…worthy of someone who could flex and make other hard with his power.
Somehow Aaron knew the gains were meant to be minor and temporary, but he was determined to change that narrative. “I want it all…I want all the muscle…and I want it forever,” he told himself.
He could feel abs forming where his skinny-fat belly had been, tightening into the core of a bodybuilder. And then he felt his ass harden, growing massive glutes that would look so delicious in the tight short-shorts he was going to wear from now on.
“It’s not enough!” thought Aaron. "Give me more!" His body responded by pumping up his shoulders and back, as if he had done hundreds of pull-ups every day for a decade.
After that the growth started to slow, but Aaron refused to let that happen. He sucked harder and harder to Hoyt’s cock, drawing out more of the magic cum. “I’M NOT FUCKING DONE!” roared inside his brain. “I WANT MORE! I NEED MORE!”
And just like that, the growth restarted. He could feel his legs growing longer and stronger. Thankfully he had completely disrobed or his pants would be choking the muscle, but they were free to reshape into those of a powerhouse. DeMayo in his prime would have wept at the sight of Aaron’s freaky new stems.
He could feel his feet enlarging as well, going from a measly size 7 up to size 17 – perfect for a man who was no longer 5’6” but 6’6”. His weight was shooting up as well – from 100 to 150 to 200 to 250. He eventually topped out at 350 pounds of beef, bigger than both Hoyt and Max ever dreamed they could be.
Aaron wanted to be a god among men, and he wasn’t willing to settle for ordinary.
“I’m fucking in control,” he thought. “And I want more! I want everything he can give!”
Aaron sucked and slurped on Hoyt’s shrinking cock and took every last ounce of cum he could get, and sure enough, he got his wish. Not only did he take size and strength, but he sucked out confidence and swagger. He sucked out the desire to be seen, noticed, and pleasured. He sucked out the good looks, the cleft chin, and the blond hair. He sucked out the porn star dick. He sucked out everything Hoyt knew about pleasuring other men. He took everything he wanted!
Finally, Hoyt was left drained and he opened his eyes. He gasped as Aaron stood up from the bed – gone was the puny man who had been sucking him off, and instead he completely transformed into a hulking bruiser. He looked like a morphed version of a bodybuilder, with gigantic arms, chest, shoulder, and legs, and a huge erect cock sticking out from under his shredded abs. Additionally, the man he had gone to bed with had a cute face with brown hair, but this man had wavy blond hair and a face so handsome and sharp that any movie producer would beg him to star in their picture.
“What happened?” asked Hoyt. “My cum only changes guys a little.”
Aaron bounced his beefy pecs. “Most guys don’t know what they want, but I did. I wanted to become a fuckin’ real man. A fuckin’ perfect man. And thanks to your cum, little guy, it happened.”
Hoyt wasn’t sure what Aaron meant at first, but then he raised his head to see the changes to his own body. Gone was the big, beefy physique he had built up over the past few years, and it was replaced with a lanky torso, thin arms, and spindly legs. All the muscle he had used to intimidate people was completely gone. He flexed his left arm and only a tiny little ball of weak muscle appeared. Even worse, his cock had shrunk down from its previous heft to a small one-inch nub.
“No!” the former bodybuilder cried. “I can’t be this tiny. Please don’t leave me this way!”
Aaron laughed, and then picked up his old shirt from the floor and tossed it onto Hoyt’s newly frail body. "I know a puny guy like you couldn't possibly handle me in bed, but at least you can hold my shirt, right?"
Hoyt remembered saying something similar to Aaron earlier in the day. “C’mon, you know I was just kidding, right? You need to give me a chance to get my muscle back from you.”
“Look, I’m sorry, but it's just not a fair world, is it?” said Aaron, hitting a double bicep pose. “God decided to give me these mighty pythons and left you with toothpicks. I got tons of muscle and strength, and you’re left with weakness and frailty and delicateness. That’s just how it’s fuckin’ gonna be.”
The huge naked man then picked up the set of keys from the bedside table. “I’m taking the truck, too. It’s too big for you now, so I’ll send over my crappy Celica for you to drive later. And I’m taking all the cash and credit cards in your wallet – the Big & Tall and supplement stores should still be open, and I need a few things.”
Hoyt stood up, wobbled from the weakness, and sat back down on the bed. “Please. Please leave me with something. It will take me time to grow my muscles back, and I’m defenseless right now.”
“How ‘bout I leave you with a kiss?” Aaron knelt down so his face was in front of Hoyt’s, and then he jammed his tongue inside his mouth. The big man immediately began to suck as hard as he could with his giant lungs and managed to inhale quite a bit of Hoyt’s saliva. In doing so, he also sucked out Hoyt’s ability to grow muscle mass quickly and easily…something he had forgotten before. He then thought about himself working out in the gym and easily growing bigger and bigger, and how everyone was going to be jealous of his superman body.
After fantasizing about it for another 15 seconds, Aaron wordlessly stood back up and headed out the door to his new and improved future.
