An alien race employs sleek advertisement to turn Earth's top athletes into a horde of docile bodies in tubes, being pumped of their cum to create an army of supermasculine studs.
Suddenly, the huge figure locked eyes with Rodney, smiled and shouted his name. At this point, he recognized the basso profundo as a deeper and indelibly richer toned version of his friend Stanley McMichaels, a linebacker who had some months ago been transferred to a training program none of the teammates knew much about, but which they’d all heard amazing things about. And here, in front of them, stood a testament to the wonders the program worked. Stanley was now by far the largest and most impressive player on the team, and his wide girth, huge legs and arms as if cut from granite in fact hid his slightly taller stature. Rodney suddenly felt a huge wave of elation at seeing his friend in such amazing condition. He went to hug Stanley, and as the two commenced sizing another up, Rodney noticed a strange dullness in Stanley’s eyes. He didn’t have long to consider it, though, as the sense of elation he’d initially felt transformed quickly to euphoria. Rodney felt incredibly horny, and his cock quickly expanded in his jock. As he started losing self consciousness, he noticed he was cumming. The cum, much more than normal, quickly dribbled down his legs and formed a puddle between his feet. The puddle morphed into a sphere, and the sphere began rolling towards the trainer’s office. As he looked around in horror, he saw the crowd around him at various points of arousal, many experiencing earth-shattering orgasms as extreme as his own. Stains and puddles were forming all around, and one of his last recollections before becoming a permanent cum dispensary for improved and more muscular versions of himself was that he was growing
The Steelers facility was soon complete, and built according to the blueprints of the alien overlords. The stadium was turned into a breeding ground, with tanks housing all the original players, their trainers, coaches and even some of the male cheerleaders producing a steady flow of mutant muscle-zombies to feed the growing army. The improved copy of Stanley McMichaels sent to convert the facility looked on in approval. As the huge muscular bodies in the tank churned out more and more cum, he flexed into the heavens. His huge back, traps and lats condensed into an intimidating display of power, and a remote signal sent from the overlords caused his stiff 11 inch member to visibly lengthen. As it did, it stretched upward between his rock hard abs, eventually sidling between his deep pec cleft. As it continued to grow upward, a bead appeared on the head of it. Stanley took his cock head in his mouth as he continued to flex for the heavens. Instantly, his enormous balls began filling his mouth with a delicious sauce that the clone swallowed down. He immediately began to grow, all of his musculature swelling obscenely, until he was nearly twelve feet tall and six feet wide.
He continued suckling and growing, greedily receiving his reward from the alien overlords for a conversion complete. His muscles bulged outward,, impossibly dense. As his now 2 foot long cock plopped out of his big mouth, he let out an animalistic roar that could be heard for miles.
The city would never know what hit it.
So Greg had signed up, and in a few weeks he packed his duffel bag full of creams, vitamins, supplements and a few hours’ worth of chicken breast and rice, as he made his way on the train to the location of this “muscle conditioning program”. The prices were outrageous, but he’d heard so many swooning about the supposed results that his envy of Pedro overcame any cost-benefit analysis in this case. His cock was hard the whole way and he rubbed it through his sweatpants, looking idly out the window at the landscape lolling past. He thought of himself being larger and more impressive than Pedro, and this thought pushed all other reservations away for the time being. Once or twice he got awe-inspired stares as other passengers passed by the seemingly dazed muscle man in permanent arousal, overlarge member straining the loose material.
Eventually the train arrived, and he called a taxi to bring him to the address he’d been given. Once there, he looked for, and found an entrance, and rang the bell. Two of the most impressive specimens he’d ever seen, much bigger than either Pedro or himself, and yet cut to insane levels of perfection, greeted him. Their faces were chiselled, yet the magazine good looks did nothing to hide the dullness in their eyes. There wasn’t much going on up there, and it was obvious the two spent most of their focus on sculpting an insane physique, and he wouldn’t be surprised if the had trouble spelling “deltoid”. They both wore a “uniform” of what looked like a tight-fitting lycra shirt and compression pants, that did little to hide bulges worth writing home about. The two smiled stupidly at each other and at him, seemingly seeking approval that they were, in fact, “good boys” for having less fat on their bones than a low-calorie yogurt.
“Hi!” said the one. “You must be Greg!”
Greg nodded and the stud was obviously pleased at his discovery, the cords in his neck bulged and his cock stirred a little in its dugout.
“Come in, dude!” said the other one, who introduced himself as Doug. The first one’s name was Matt, and the two had been old workout buddies who had joined the program together to advance their gains. The two had gained roughly 100 lbs of muscle in 3 months, they claimed, and flexed for Greg. Greg was especially impressed by Doug’s traps, which literally went to his ears., a huge pyramid to the only god in Doug’s life: muscle.
Greg, Matt and Doug joked around in the hallway for a few minutes until they heard a voice behind them:
“Boys, do bring Mr. Morrison to my office and don’t hold up his… progress.” The enormous man in the white coat introduced himself as Dr. Moravian, and he generously shook Greg’s hand. Dr. Moravian’s hands were strangely cold, but Greg shrugged it off. Either way, it matched his personality, which was certainly more chilled than the warmth that exuded from Matt and Doug, who resembled two overbuff lapdogs. Dr. Moravian led Greg to a small door on the corner of the hallway, with the wall of muscle following behind.
“As you can see from our boys here,” said Dr. Moravian, gesturing to the two muscleheads in the corner, “our results are dramatic and extraordinary. I’m sure these two have informed you of their gains while enrolled in the program?”
Greg nodded and the rest of the conversation went by in a blur. Greg agreed to enroll in the program, signing paperwork and nodding occasionally when questions were raised, but never taking his eyes off the delectable duo across from him. Dr. Moravian gave him a glass of something to drink, which he hardly heard him describe the nature of: something-something-electrolytes-something. He downed it, and was just about to put the glass down, when he froze. He couldn’t move! As if on cue, Doug moved over to his feet and began removing his sweatpants, revealing his jockstrap-covered bulge. Matt meanwhile moved over to his torso and applied pressure to his jaw, forcing his mouth open. While he felt something soft, hot and strangely wet on his asscheeks, Matt whipped his horse dick out of his compression pants and began slapping Greg in the face with it. While Doug was rimming Greg’s ass, preparing it for entry, Matt stuck his meat in Greg’s mouth and began pounding it, slowly at first, and then picking up speed.
Suddenly, his asshole was exposed, and in one motion, Greg felt himself being speared to the hilt. Strangely enough to him, it didn’t hurt so much as it filled a deep longing in him to have a cock there. Doug began rocking and Matt picked up his pace. The two high-fived each other as they fucked Greg from both ends. Greg felt strangely aroused from the whole experience of being fucked by two ridiculously muscled studs, and his arousal increased as the two neared orgasm. The two came in unison, filling him with a liquid that burned as it spread inside him. His cock stood on end suddenly, and his whole body buzzed. He felt like he had an incredible gym pump, and felt himself swelling a bit. At the same time, his cock erupted by itself, and a hot, translucent goop collected in his corrugated abs. He strangely kept coming, it was the most intense orgasm he’d ever experienced—he didn’t want it to end—and the goop began running down the table, collecting in a puddle on the floor. Unbeknownst to Greg, the puddle began forming into a blob, and the blob grew as he came more and more. Soon, a replica of Greg, identical in every way save for being much more densely muscled—and taller—and sporting a larger cock—stood beside him. Greg could still not move, and at this point, his improved twin was chatting with Matt and Doug:
“Hey, what’s up, dudes?”
“Not much, brah. About to strap this sucker in and take him to the tanks. Wanna come?”
“Hell yeah, brah. Count me in!”
Matt went over to a cabinet and retrieved some folded clothes, which Greg’s bulkier clone put on: the same tight-fitting stretch shirt and compression pants the other two dimwitted musclestuds wore. As Greg II was dressing, Matt and Doug began strapping Greg I to the table, which converted to a gurney, which they pushed down the hallway towards to large doubledoors, from which could be heard a loud mechanical buzzing.
They passed through the doors and Greg, still immobile, was presented with an enormous warehouse filled with huge tanks, in most of which huge, strapping musclemen hung suspended in a liquid resembling glass cleaner. Attached to each one were hoses to his face and mouth, and another to his cock, and a third snaked up their asses. All of the men were at peak physical condition and each seemed to spasm every few seconds. Greg was wheeled to one tank that was not yet occupied where he was unstrapped. A crane was activated that gently lifted the big man like a toy, and he was slowly lowered into the tank. The liquid felt warm, and it seemed to adjust itself to his body temperature. His facial mask lowered and attached itself to his head, and shortly thereafter he began feeling a strange sense of abandon and arousal. Just then, a tube snaked up his ass, which had been loosened earlier by Doug’s big python. It immediately began stimulating his prostate and injecting a special nutritional paste into his ass. He saw another device directing itself toward his cock and balls, and suddenly felt intense pleasure as it locked into place and began sucking him of his vital juices. Just then the parasites entered his mind via the special nutritional paste being injected into his ass and mouth, and he prepared to produce the second (of many) soldier offspring for the alien invasion.
Greg groaned in pleasure as he fed the tube what it wanted, bigger and more muscular than Pedro, finally…
