Please note I wrote this story basically in French and then I translated it with Google ^^

 

PART 1

Craig is a discreet and shy 17-year-old who has trouble making friends. His puny physique does not help him to become popular, neither with girls, who do not look at him or make fun of him, nor with boys, whom he would like to seduce but none of whom are interested in him. He's having a hard time finding his place... However, he had already tried to integrate by trying various sports, such as football, basketball or even rugby, but he had to face the facts, it was not his thing. Recently, he wanted to join a weight room, but the vision of all these young, muscular and arrogant males paralyzed him. What would they think of me? He said to himself. He was sure they were going to make fun of him and his frail body. He couldn't overcome this feeling and turned around. But the idea of modifying and developing his body to gain self-confidence was something he wanted to pursue. Because if the boys he likes don't look at him, he knew very well that it wouldn't be the same if he in turn displayed flattering abs and arms that folded the sleeves of his t-shirts further.

Totally petrified at the idea of setting foot in a gym with the body that was his and finding himself surrounded by guys his age with at least sculptural physiques or, even worse, the size of a bodybuilder, Craig then wanted to train at home, out of sight, in order to modify his appearance, before tackling serious things in the gym. He needed to gain muscle. Not in an exaggerated way, because he knew very well that his genetics would not allow it, but enough to be able to face the comparison with all these beautiful kids who made him fantasize and whose bodies he dreamed of having. Luckily Craig was a pretty good student. Since he had no friends or any hobbies, he spent his free time with his head buried in books and on scientific sites. The mechanisms of the body no longer held the slightest secret for him. He therefore knew very precisely how to train and what to eat to develop muscle mass. But what he lacked... was time. So he wanted to speed things up. Knowing that the key to the process of gaining mass in bodybuilding was the protein intake coupled with targeted training, which served to solicit the muscles, to push them to their limits, to see beyond their limits so that They “get damaged”, so that proteins can then “repair” them. This is how muscle mass is created and the body develops. He then imagined a way to create this process artificially so that muscles would be able to be pushed to their limit and regenerated at the same time.

He sought the best cellular stimulation in order to implement this muscle development mechanism. He combined various doping molecules and synthetic proteins in order to progress in his reasoning. But the first simulations did not give particularly conclusive results. Despite this, Craig did not get discouraged because he knew that his reasoning was coherent and that he was on the right track. Every evening after school, and often until late at night, for several weeks, he didn't give up. And then one day he found the idea that would change everything. He understood that the process he had to copy was that of plants in nature. They were capable of growing at incredible speed if the conditions were all right. He therefore made the parallel with the needs and contributions necessary for our muscles to be able to develop in a similar way.

And after almost 3 months of research and virtual simulations on the internet, he finally had the formula that would be the right one. But to be sure, he needed to be able to test it in real conditions, that is to say on a living being. But how, and especially on whom? He hesitated because he had to find a subject on which the effects could be sufficiently visible and especially as a guinea pig which would allow him to know if it could work in the same way on a human being afterwards, and ultimately on him in this case. After thinking about the subject for a long time, he had an idea that would allow him to kill two birds with one stone. That of finally knowing if his formula was going to work but also of getting revenge on a guy who had been making him miserable for years in high school. What better test subject than another human his age after all, he said. “If it doesn't work on him, I'll be fixed, and if there are any side effects, it might as well fall on a scoundrel. » Craig definitely relieved his guilt by completing his reasoning with “And if my formula is correct, in the end I would have given this big bastard a fucking gift”. In Craig's eyes, the game was clearly worth it. He therefore synthesized the molecule he had designed in simulation, put it in a neutral physiological solution and placed it in a small vial. Now all that remained was to find a way to get it ingested by the target Craig had chosen.

The next day at school, Craig scanned his surroundings for the bully who had been ruining his life for years. And it didn't take long for this shit to appear. As usual, the guy didn't miss the opportunity to make fun of Craig, calling him a twig and asking him if the wind hadn't carried him away yet. His friends around laughing at his rotten jokes. Craig no longer had the slightest doubt now about who would indeed be his guinea pig. And he was so excited. Almost hoping that he was wrong and that there would be an avalanche of unwanted side effects. He knew when the right moment was. It would be the one in gym class, just when Alex was changing. Craig would discreetly pour the contents of the vial into his flask. As his body and muscles would be used during the course, the effects would be seen directly. And Craig could watch it for himself when the group was back in the locker room after school.

He therefore managed to pour the contents of his formula into Alex's bottle. Now all we had to do was wait and see if it would work. Today's gym class was a class based on cardio and physical strength. Sprint, pull-ups, push-ups... Alex, who was a great athlete, rather determined, had no problem keeping up the pace or even outperforming the other students normally. But that day, he seemed unleashed, with incredible energy and his strength seemed multiplied. He even challenged the teacher to arm wrestling, his arrogance was so great and he beat him! Craig couldn't believe it and for him there was no doubt, it was all the work of his muscle development formula. The class ended and the students returned to the locker rooms. The moment Craig had been waiting for. The one where he would finally discover how Alex's body had developed. And when he took off his t-shirt…

The transformation was obvious and impressive. His lean and aesthetic physique from before, already drawn and traced, of course, had given way to that of a body-built athlete. His pecs were now large and dense, much more massive and heavier than before, displaying a new shape and incredible definition. Just like his arms and shoulders, which seemed to have doubled in size and displayed breathtaking vascularity. Alex looked like he was about to enter a bodybuilding competition, his body had become so impressive and veiny. Alex was stunned by the reflection he saw in the mirror but didn't ask too many questions, probably thinking that training had caused this incredible muscle congestion. He was just proud to strut around with this physique of a man, he, the kid of barely 17 years old, and added tons in front of his comrades, by contracting among other things his monstrous pecs and his congested arms which must have been around 45cm easy to present, and which would probably have a hard time fitting into the sleeves of his t-shirt. The entire group present was in awe of the muscles that Alex proudly displayed. The young BG couldn't help but contract his impressive muscles again and again, climbing onto the benches and posing as if he were a bodybuilder on stage. And his audience seemed insatiable. It must be admitted that the spectacle was truly beautiful, especially as all this agitation made him sweat and this further enhanced his impressive muscle mass.

Craig looked at Alex with admiration of course but also a little jealousy, he who had always dreamed of having a body like that. He was well aware that he had just given one of the worst scoundrels in his school a phenomenal gift that would make him even more popular within the school but also certainly strengthen his arrogance. You only had to see how he behaved in the locker room to imagine what his attitude would be outside of it. The time for the next lesson had come. The day was almost over but they had one last hour of class left before they could go home. And Craig was obviously very impatient, because he now knew that his formula worked and that he would be able to test it on himself as soon as he got home from school, and it would boost him to the max. The last lesson of the day was an expression lesson. The students were currently working on the end of year show which would take place in four weeks. Everyone had a well-defined role and the goal was to offer content where everyone could interact with others. As a good student, Craig always put his all into all class projects, even if the rest of the group mostly didn't care. What had just happened at the gym was still on everyone's minds, and when the boys arrived in class, accompanying Alex who continued to act like a bodybuilder despite his shirt, the girls noticed directly that Alex had taken from the crowd and he was entitled, quite logically, to a shower of compliments, which further inflated his alpha male ego. His flirtatious side then took over and he couldn't help but seduce the most beautiful girls in the class by offering them a biceps pose.

Despite his shirt, we could clearly see the curve of this mass which had just swelled inside the fabric, which had great difficulty containing the impressive biceps. All eyes were obviously on him and the young man loved it. Being the center of attention made him enjoy it and fueled this ego that seemed to have no limits. This bicep even seemed even bigger than it appeared to be earlier in the locker room when it was revealed after sports class. Craig logically could not help but watch the spectacle that Alex was offering, captivated by the charm of the BG, sublimated by this new mass which now made him so sexy. Even if he was a detestable person, it had to be admitted that the young man exuded an animal attraction which made him an irresistible sexual object. Alex contracted and contracted again this arm which had become enormous, feeling that his audience was asking for more. He was jubilant at feeling so desired, and the feeling of all power that his new muscles gave him, and in particular those big arms, making him a true alpha male, filled him with arrogance. Contracting his bicep again and again, the ball of muscle seemed to fill more and more of the fabric which began to tighten so tightly that it finally cracked. As if this mass had continued to grow by dint of inflating it. Unable to take it any longer, the sleeve of his shirt gave way, revealing the splendor it contained.

PART 2

This didn't stop Alex who continued to pose despite his astonishment, which quickly turned into pride because he no longer had any doubt about having become the most muscular guy in school and intended to make it known and enjoy it. His comrades filmed and took photos of the surreal scene, and of this impressive body that Alex revealed to everyone, who finally took off his shirt, which was now in tatters. Craig had of course observed the scene and was also surprised that this bicep had, it seems, continued to grow in the absence of targeted training. As if these muscles had been able to develop on their own without real stimulation. “Could the simple act of contracting your biceps be enough to generate muscle mass? » he wondered. He would have to investigate that later. The bell finally rings, putting an end to this school day and freeing the students at the same time. Craig left Alex and his oversized ego behind and hurried home to finally test the molecule on himself.

He was understandably a little nervous because he knew that once he took the dose, there would be no going back and his life would be changed forever. Starting from nothing, Craig didn't really know how his body would react and how much it could develop. He who was not at all athletic and therefore had no visible muscles, he wondered if the effects were going to be as conclusive as they were for Alex earlier. “There’s only one way to find out…” he said to himself, and swallowed the contents of the vial. Identically the same as the one he made Alex take. For the process to work optimally, he now needed to use his muscles. So Craig started doing push-ups, pull-ups and sit-ups in his room. Then he remembered that his father had some gym equipment in the cellar that he no longer used, and said to himself that this was definitely the perfect opportunity to take advantage of it. So he went down to the cellar and without giving himself a break took the dumbbells left there by his father and began to do the repetitions. “Damn, those 10kg dumbbells look really light… Let’s try the bar and load it up a bit. Let's use these 10kg plates to double the dose. » And Craig then did sets using his father's bar, loaded with 2x 10kg. A load usually used to warm up the pecs that he used for his arms. “I should have gotten to it sooner. I love this feeling! » He performed biceps curls and chest presses almost effortlessly. After an hour of training, Craig felt no fatigue. He continued with a set of 500 abs. Now it was time to see the result. Feverish, he went to the bathroom to take off his t-shirt and see the changes.

" Oh my God !! I have abs!! » He had barely lifted his t-shirt when he saw a block of eight flattering, perfectly defined abs appear. Then he continued and removed his t-shirt completely, revealing his entire torso. We could see a dry and cut upper body, where each of the muscles was perfectly visible. Shaped, striated pecs, very rounded and swollen shoulders, and arms displaying a nice curve at the level of the biceps, which were marked with a beautiful large, becoming and sexy vein. Craig couldn't stop admiring himself in the mirror with a feeling of accomplishment. It was over for him to be the weakling of the class. He was going to be respected, admired and even coveted, joining the level of these other guys who impressed him so much in the weight rooms. All this effort had finally tired him. He decided to go to sleep, dreaming of the next day when he would be able to settle his scores. When he woke up, Craig took great care to carefully choose his outfit for school. He wanted to be sure to impress his comrades and, above all, to perfectly showcase his new muscles. So he decided to wear a simple black singlet and jeans. This outfit gave him a BG look which did not displease him.

As one might expect, as soon as he entered the school, all eyes were on him. The girls and boys in his class rushed over, not believing their eyes. And Craig was quick to show everyone his sexy chocolate bars. Alex then entered the class, disgusted by the attention Craig was generating, but also challenged by his transformation. “You’ve taken up sports, I see. But how did you manage to gain mass so quickly? It’s just impossible…” " I don't know. I just did a few push-ups last night and woke up like this this morning. Maybe your sudden weight gain yesterday had an effect on me too… who knows? » Craig replied, looking Alex straight in the eyes and giving him a big smile of defiance. “No matter what you do, I will always be the biggest in this school man! », replied Alex, displaying a massive double bicep as a conclusion.

The day passed and Craig couldn't believe his new popularity. He had become the number one topic of conversation in the entire school. When he came home that day after school, he decided to repeat the experiment from the day before and see if his body could grow again. He was already very satisfied with the level obtained, but what he wanted now was to surpass Alex in terms of muscular development, because it is true that the latter still greatly exceeded him in terms of mass. Craig wanted to be able to put his cackle down once and for all, and to do that he needed to develop his arms to surpass those of his arrogant classmate. So he took a new dose, the same as the day before, and went to the cellar again to take advantage of his father's equipment, this time with the intention of pushing and lifting even heavier than the loads of the previous day. . He started with the chest press and put 40kg on each side. With the bar it made a total of 100kg, which is a lot for a 17 year old boy. But Craig seemed to have no trouble lifting the load. He then added 20kg more to each side and began to really feel the work. He did the same with the arm exercises. Increasing the load by 10kg each set. He wanted to test her strength by pushing her to her limit. And as a result after almost 2 hours of training, his physique had once again exploded.

He could now stand up to Alex and put down his cackle by displaying arms that could stand comparison with his own.

PART 3

The night before, Craig had a hard time falling asleep. His new body obsessed him. This feeling of being able to touch his pecs so massive and hard, and his arms so big, excited him terribly. He couldn't believe that 48 hours ago he was still just an insignificant 17 year old, while now he had become a young alpha male, and perhaps even more muscular and sexy than the guys who fantasized in his own dreams. He had become his own fantasy and knew very well that he was going to become one for other gay people as well.

He then decided to take a few photos of himself in front of the mirror and post them on a dating app for boys. This same app where he was going to watch the handsome muscular kids from the surrounding area but where he had never dared to send the slightest message until now. This time he suspected that he would be the coveted object and that he would be able to take advantage of this body of a Greek god also for fun.

In the meantime, seeing himself in his mirror and contemplating this magnificently muscular and massive body had given him a boner and he was now hard as a bull. He then continued to contract his big biceps, which put him in a state of unprecedented trance, causing a stream of precum to gush so abundant that it flowed down his big, erect, steel-hard cock, before continue to flow down his imposing, hairy thighs. And the more he posed, the more it turned him on. The budding stream of semen flowed again and again. Until the moment when, with a bestial growl, he couldn't take it anymore and ejaculated, projecting his cum violently onto the mirror in front of him. The pulsations of his intense orgasm made him spit jets of sperm from his cock which ended up completely covering the mirror in his bathroom. “Wow!! It was intense! » he said to himself after regaining his senses but still displaying a huge smile on his face. He wiped up the mess he himself had made, looked at his body one last time and finally went to sleep, still thinking about what had just happened. He was convinced that his formula had something to do with it, and that there were undoubtedly many other things to discover about it.

The next day when he woke up, checking his phone, he saw that he had received more than fifty messages following the photos he had posted the day before on the dating app. So he took a look and if the majority of messages came from uninteresting, ugly, old or perverted guys, there was at least one that caught his attention. It had been sent by Amit, a classmate who was also harassed and terrorized by Alex.

Amit was from India and arrived at his high school last year. The young man did not speak the language well when he arrived, which isolated him from the other students and earned him some teasing as well. He had been adopted by a wealthy local family. Since then, Amit had fully integrated the language and spoke almost without an accent. But Alex had taken a dislike to him at the time and hadn't let go since. His message was not a flirtatious or sexual message, but rather a cry for help. Because Amit had noticed yesterday that Craig had quickly gained muscle and that this had allowed him to acquire confidence and that he could now stand up to Alex, because the latter would think twice before take it from him. Amit begged him to help him and tell him his secret so that he too could defend himself. Her message had touched him, but he hesitated. This meant revealing his secret and if he ended up finding out, he didn't know what the consequences would be, and he wanted to avoid that at all costs.

That morning when he arrived at school, Craig was more confident than ever, displaying confidence and poise because his muscles were even more impressive than the day before, and this did not escape the other students. The guys who had admired him the day before came back to greet him and congratulate him on his physique which had once again incredibly gained muscle mass and which now made him the most handsome guy in the whole school. Craig felt flattered by all the attention he was getting and he understood a little better how Alex must feel since he was now in the same position as him. Exactly, Alex arrived, looked at him and the expression on his face was unmistakable, he had just realized that Craig was now as bad as him, if not even more so perhaps. He walked past him and said nothing. Craig followed him with his eyes and saw that Alex was heading towards Amit. With Craig's transformation, Amit was now Alex's main pain and Craig blamed himself a little because by saving himself he had unintentionally made his classmate's condition worse. He approached the small group and, addressing Alex sharply, said: “Leave him alone! » “Do you think you’re his mother? » replied the muscular and arrogant hunk.

Craig wasn't used to this kind of confrontation, but his new body gave him the confidence to stand up to Alex and added: "You're done terrorizing the weak. If you want to pick on someone to feel important, do it with someone of your own stature! » Alex managed an annoyed smile but didn't want to provoke Craig given the muscles the latter was showing. He took a step aside and said as he left: “We won’t stop there, you can believe me. Both ! » And then walked away.

Amit thanked Craig for his intervention even though he knew very well that Alex would come back later. And Craig knew it too… Craig then spoke to Amit: “I’m sorry for causing this. But I will help you. » He invited Amit to join him at his house after class. Craig blamed himself terribly and he knew he had the solution to solve the problem. But he didn't want to reveal his secret. He was therefore going to have to play it subtle with his comrade so as not to ruin everything.

That same evening, Amit arrived at Craig's house. The man had prepared a protein shake for him. At least that’s what he told his friend. He offered to become his personal coach and train him to help him gain mass. Craig knew perfectly well what was going to happen, but Amit had to think it was from his training and nothing else. Amit drank the shaker before starting to do the exercises. Craig made him do push-ups, pull-ups, push weights on the bench press, curls on dumbbells and barbell. He pushed him to his limits. If Amit didn't yet realize anything, Craig was already noticing the changes. His friend's muscles were appearing and even starting to become imposing. Craig himself couldn't believe how quickly Amit was able to synthesize muscle mass. His determination in training undoubtedly had something to do with it.

Amit did not seem tired and did the repetitions one after the other. He was now even capable of lifting loads as heavy as Craig's, for example doing bicep curls on the bar with 40kg of load! Craig couldn't believe his eyes at the strength of his friend. “It’s crazy man! Where does this strength come from? » Craig asked him. And Amit replied “I have no idea my friend, but I feel fucking good! And look at those arms!! My biceps are getting huge!! » Indeed, Craig was well aware that his friend's biceps were growing impressively. They were now, and in just one session, almost as big as his own.

After 2 long hours of training, Amit finally seemed to have exhausted all his energy. That's when he walked towards the mirror that Craig had placed in his basement.

Amit naturally struck the pose and first contracted his right bicep while not taking his eyes off him. A beautiful, big ball then formed on his arm and revealed a swollen, rock-hard muscle. “Damn Craig, did you see that? » And Craig replied, “Yes mate, I see it. You won’t have anything to fear from that big bastard Alex now.” The two young men then spent the evening comparing their muscles and relaxing, imagining how their lives would now be much better thanks to their new muscular bodies.

Seeing his new friend flexing his pretty biceps and contemplating his sexy and muscular body gradually excited Craig who felt his big cock swelling in his shorts. He felt it engorge with blood and become bigger and harder. He also felt his precum lubricating his tip. He was also starting to have a hard time hiding it. Amit realized that his friend was enjoying the show and he himself was not indifferent to the impressive body of his new coach either. Craig wearing a singlet that particularly showed off his pectoral muscles, his broad, puffy shoulders, and his massive, veiny arms. The spectacle was absolutely beautiful and Amit also had an erection that he was starting to have a hard time hiding.

PART 4

The sexual tension was starting to get out of control between the two muscular hunks. Both being totally under the spell of the other's body and muscles but neither daring to reveal it.

It was then that Craig's father entered the room. " Hi guys ! » Then he noticed the impressive musculature of the two boys, who looked at him a little uncomfortable and embarrassed. “From what I see, you got a lot of use out of my workout equipment. You are quite right. But if you want to continue to progress, and given the results you would be wrong to stop there, you are going to have to join a gym because there are not enough weights here unfortunately. At this point the two young handsome guys left the room. Not really knowing what to say, Amit thanked his friend and said “See you tomorrow at school! ". Craig didn't know what to say either and greeted his friend before going up, alone, to his room.

Intrigued by what he had just seen, the father who remained in the cellar wondered how his son had been able to gain so much muscle in such a short time. Digging around a little he found the empty shake that Amit had drunk, then he noticed the small empty vial barely hidden a little further away. Craig did not have time to properly remove all the elements due to the arrival of his father. The latter wondered what this vial could possibly contain. Then he noticed that it was not completely empty. Intrigued by the effects of the product it must have contained, he drank the last drops. Craig's father had always been athletic and took care of him by training modestly at home two or three times a week. A few repetitions to maintain the machine and keep in shape. Seeing these boys in great shape made him want to do some exercises and push a little weight.

He loaded up the chest bar and began his workout. He directly felt that these loads were surprisingly light compared to the efforts he usually had to make. He then decided to challenge himself and put all the weights present on the bar. Which made a total of almost 150kg. A charge that he had never managed to push so far. His record being 120kg and for only 2 or 3 repetitions. There he was able to do around fifteen repetitions at 150kg... He couldn't believe it.

Without realizing the changes his body was beginning to make, he continued his training with the dumbbells to congest his biceps and triceps as much as possible as he loved to do. Here again the loads seemed strangely light to him. He therefore decided to take the bar to work his arms and gradually increased his loads to reach 50kg! A load that even professionals have difficulty lifting to work their biceps. But for Craig's father it didn't seem impossible. He did several sets of a dozen repetitions.

After more than an hour of training and lifting several tons of cast iron, he couldn't take it anymore. It was then who saw himself in the mirror and noticed that his body had exploded. His muscles were congested to death and each of his muscles felt dense and heavy and displayed impressive definition and vascularity. When he saw her body it excited him so much that he couldn't help but jerk off in front of the mirror. And the scene was incredible. All this power brought him such pleasure that his orgasm was the best of his life. He also put it everywhere because his sperm gushed out so abundantly. The flow seemed inexhaustible and his juice continued to flow for long seconds after spitting out the puree.

His cock was still so hard after that that he continued to stroke it for several minutes. She seemed cut from the same steel that had shaped his incredible body as a forty-year-old father. He was still so excited that he went upstairs to find his wife in the marital bed that evening and fucked her several times in a row, as if they had regained their lost teenage years.

The next morning, Craig of course had no idea what had happened in the cellar the day before. So he got up as usual, didn't meet anyone and left for school like every morning. On the way he checked his messages and saw that he had once again received dozens of responses following his photos posted two days ago. Again there wasn't much to stand out. But the profile of a guy retained despite all his attention. His name was Henri and unlike the other posts, this one asked more for advice on training, and in particular how to get big biceps. It was in particular those of Craig that the young man had obviously fallen for. Craig found him cute and decided to respond to him.

When he arrived at school he saw that Amit was already there and that he had not waited for him to display his new muscles and in particular his two beautiful, big biceps which he proudly displayed like trophies. It must be admitted that in his black t-shirt it particularly highlighted them.

Then Alex arrived. He rushed straight to Amit and said, “Damn dude how is this possible!? Did you turn into the fucking Hulk too!? » Annoyed, he wanted to grab Amit but the latter didn't let it go and punched him in the face and exclaimed: “How good that feels! And stay on the ground you cockroach if you don't want a second one. I could do this all day if I had to.” Craig, watching the scene, smiled, also thinking that it was time for this bastard to finally be put in his place. And what had just happened had clearly calmed down Alex who, humiliated, left the class. We didn't see him again all day. It was also the last day of school before spring break. Two weeks that would do everyone good.

PART 5

This break was going to be for Craig and his friend Amit the opportunity to finally open the door of a gym and confront other guys their age lifting weights, who they were usually content to watch on the internet or in the street. Their first time was this Friday after school. They were both pumped up and determined. Once in front of the front door they were a little more hesitant, but decided to enter together. When they arrived at the counter they asked the manager to sign up for a membership. The guy looked at them in surprise and asked, “Which gym were you training in until now? » They said “None, it’s our first time in a gym.” The guy obviously didn't believe them and thought they were making fun of him. Two brooms like them had to come from somewhere. He added: “Are you planning to prepare for a competition? ". To which the two friends replied: “No, we just train for fun.” And the guy added in conclusion: “What a waste! ". After filling out the form, the guy gave them their locker room keys and the two friends went to change before returning to the room, ready to fight.

A little clumsily, they went through the machines and repetitions. But strangely, their strength didn't seem incredible. They even gave the impression of struggling. The other guys present looked at them intrigued, seeing two new guys arrive but quickly returned to their training seeing that they did not seem capable of performing in any particular way. The two friends didn't really understand why they were no longer able to lift the same weights as before. But Craig then understood that his formula had to have a limited duration of action. Once the molecule was completely eliminated by the body, the latter resumed functioning normally, nevertheless retaining the muscular gains acquired.

A little disappointed, especially Amit who did not know that his winnings were linked to taking a molecule designed by Craig, the two friends left the room and returned home.

Craig, for his part, wanted to find out for sure and decided to return a little later, but this time having ingested a new dose. And as expected, his performance this time was very different. He could once again lift monstrous loads and was even capable of lifting the entire weight available on a machine with one arm. All the guys present stopped to gaze at this young colossus who was achieving performances that even the biggest bodybuilders in the room were not capable of. They were also in awe of the size of his muscles, which when used in this way began to grow once again. Craig was congested like crazy and every muscle felt like it was about to explode. His pecs, shoulders, back and of course his arms seemed to have doubled in size. The loads here were much greater than on his father's machines in his basement and Craig could increase the intensity of his training almost infinitely. The guys present even came up to him to take selfies with him.

And Craig got into the game and happily posed with those who asked him. He almost felt like a rockstar and savored these moments of glory, he who had been crushed so many times by others. Now it was his turn to be the coveted person. After two hours of intensive training, Craig couldn't take it anymore. It was time for him to come home. But as he was about to leave the gym, he came face to face with Alex.

When he saw him, the latter had a shock. “Holy shit” he exclaimed. “You’re even bigger than this morning!” » Alex then asked him what his secret was. And Craig replied: "There's no secret man, it's just training and a suitable diet...". “Stop kidding me man, no one can put on that much muscle that fast. » And Craig responded by flashing his best smile and contracting his huge biceps. At the sight of Craig's monumental arms, Alex had an erection. Something that did not escape Craig, who was surprised because he did not know that Alex was gay. Embarrassed by the situation, Alex turned around. But as he walked away Craig caught up with him and said: “Wait Alex! I didn't know you were gay..." “Would it have changed regardless of what you knew? » Alex replied. “Why were you always picking on me and Amit? Was it because we were gay? » Craig asked him. And Alex replied “I didn’t know how to handle it… I thought maybe by getting your attention maybe we could be friends. But I went about it completely wrong and instead of getting closer to you, I made you hate me. And the more you hated me, the more I attacked you..." “You should have tried to talk to us about it…” Craig told him. “I know… but I had gone too far and therefore there was no going back.” Craig then raised his arms parallel to the ground and contracted his two huge biceps in front of Alex while showing him a big smile.

“But what are you doing Craig? » Alex asked him while having more than ever his stiff and hard cock in his pants which he could no longer hide at all. “If that’s what you like then I’ll give it to you. Look at this enormous mass of muscle, hard as steel, and capable of lifting tons. I'm posing just for you..." Craig replied. “Do you like what you see Alex? » Already wetting his pants with the precum seeping through the material and that cock trying to come out, ready to tear the fabric of his pants, Alex replied: “Your body is splendid Craig. You turn me on to death man… But why are you doing that? To torture me? » “No, just to show you that even though I could break you in half with this arm if I wanted, I'd rather make you hard like a bull and even make you cum with it. » Alex then kissed Craig who kissed him back. He then took the one who was still his pain a few moments ago to his house.

Arriving in his room, Alex took off his clothes and contracted his biceps in turn for Craig, who also began to get hard as steel. The terror of the school had now become a seducer who did a series of poses to seduce the mountain of muscle that Craig had become.

Craig loved the sight of this ultra-muscled hunk posing for him in private. Alex's arms were certainly less massive than his, but Alex was certainly ultra sexy. And the vision of this erect cock in front of him, and knowing moreover that his partner was hard for him and for his muscles, made the precum flow abundantly from his baton already ready for action.

That's when Alex took action. He pushed Craig onto the bed and shoved his beautiful uncut cock into his ass.

He kissed him with passion and violence. Craig was holding on to the edge of the bed with all his strength and his monumental arms seemed to have to give their all not to give in to the vigor that Alex was showing to seed his partner. Alex withdrew his big cock to ejaculate a first time then put his rock hard rod back in Craig's ass for a second round even more fiery than the first. And he filled her ass with his sperm, not bothering this time to take his cock out of the socket where it was nice and warm.

This double dose had sent Craig into orbit and now it was his turn to pour his juice into Alex's insides. It only took a few moments for Craig to reach orgasm. And he filled his pocket with everything his balls had accumulated.

Alex apologized to Craig for everything he had done to him, and Craig accepted his apology. Alex promised to also apologize to Amit, hoping that the latter could also forgive him.

As it started to get late, Craig was gathering his things and at that point Alex started writhing in pain and screaming, “What’s happening to me?! My body…MY BODY!!! It feels like my muscles are tearing!! » Craig was looking at Alex helplessly and then suddenly he saw his chest...

Veins appeared everywhere and every fiber of his muscles took shape and began to vibrate. The spectacle was impressive. Each muscle gave the impression of becoming denser and wanting to grow bigger. Alex would be clutching his fists and writhing in pain, but the sight Craig was witnessing was much different. He saw Alex's body transform in front of his eyes...

Alex's abs, already splendid, were springing out to become even more defined, hard and dry, and his arms were swelling, almost reaching the size of Craig's.

Craig understood that the dose of sperm that Alex had just taken in his ass was necessarily the cause of this new transformation. The dose that Craig had taken just before his workout earlier in the day was most likely still present in him and could therefore be transmitted through his bodily fluids and therefore through his semen. His sperm, in his conditions, therefore had the capacity to transform his partners into muscle beasts. And Alex was becoming one in front of him.

When the pain subsided, Alex sat up and felt wonderful. He felt an incredible power coursing through his entire body, and his muscles were swollen and charged like never before. You could almost hear the crack of his muscle fibers as he began to contract them. Alex now looked about the same size as Craig.

Galvanized by all this energy and incredible power coursing through his veins, Alex challenged Craig to arm wrestle him: “Come on Craig, you’re not going to give up! With your big arms what do you have to fear? » Craig felt that Alex was overflowing with energy and could only imagine how all this cellular effervescence following the transformation that had just taken place must have plunged him into a daze. He must have felt invincible. Very exactly like when Craig took his dose just before a workout. Except that here Craig had taken his last dose several hours ago already... He was therefore aware that the effects were gradually fading.

Cornered by the situation and not finding any valid excuse to serve to Alex, Craig agreed to take up the challenge launched by his opponent. The two young men stood on opposite sides of the table, joined their hands and did not take their eyes off each other. We could already perceive their mutual strength in the muscular tension which tightened their muscles and swelled their two enormous biceps which jutted out like two giant granite peaks rising towards the sky. Alex showed a happy and impatient smile, while Craig seemed more tense as the duel approached.

That’s when Alex started the countdown: “3, 2, 1… Go! » Both of their biceps contracted in unison, revealing beautiful, huge veins on their sides, which swelled and swelled again as the two massive hunks exerted their strength against each other.

Craig was no longer smiling and presented a concentrated face on which one could perceive signs of tension and even difficulty at times with a few veins appearing on his face as well as a few drops of sweat as well, but seemed to keep the distance in front of his rival, who for his part continued to display a jubilant smile, as if he was enjoying the situation, sometimes looking his opponent in the eyes, sometimes admiring his splendid biceps which did not weaken and made him proud.

That’s when Alex speaking to Craig said: “You fought well man but the game’s over…”. He then contracted his entire torso which swelled suddenly, and his biceps seemed to become even denser and harder, and Craig's forearm could not resist the force and pressure exerted by Alex, who brought effortlessly towards the table, while keeping his smile on his face. Craig's big arms could do nothing against the almost superhuman strength that Alex had just revealed.

" FUCK !!! Have you seen this sick strength man!!! How I put you down without even really forcing!!! » said Alex who came to correct Craig. The latter was disappointed. His enormous muscles weren't enough. He had just been literally turned around by his rival, who to celebrate his omnipotence stood up and flexed facing Craig.

“I feel invincible, man. Look at this body and THESE MUSCLES!! I could enter a bodybuilding competition and I would beat them all without a problem.” It is certain that Alex's body was splendid and that if he had indeed been on a stage facing other competitors of his age, they would have had no chance against the form he displayed at this moment in his room.
