Work had shifted me over to working until late at night so I've had to start working out late at night. I am usually one of the only people there but recently a guy who I remember seeing there during the day is working out when I do; thing is he has grown fucking massive! He has had to of doubled in size since I last saw him some weeks prior. My first thought, asides from envy and lust, was "Oh Lord, here we go again". Rumors had started that the gym owner will make some patrons into his...pet projects if you will, these guys would somehow blow up size and eventually just disappear. No one knew what the hell happened or where they went but we were willing to bet that the owner has a connection with a certain supplement company that has been making waves in the market with products that worked wonders, a little too well at that.
I came into the gym one night to start up one hell of a back workout (gotta hit that new deadlift PR right?) when who do I see but the man in action at the leg press! There he is wearing nothing more than a wife beater, tights, and a pair of those Otomix shoes the pros and power lifters wear. I'm transfixed staring at him pressing a max loaded sled grunting as his spandex-clad legs piston through the motion while he grunts with each rep. Once I saw what he had between his legs fighting for space in a way that can only be described as grotesque I tripped over my own feet. With one last grunt he finished his set and looked at me on the ground blushing in embarrassment as I tried, and failed, to pretend nothing happened.
Swiftly I got up and went to the other side of the gym to start doing some pull ups making sure not to meet his gaze the whole time. As I continued my workout I could hear his rhythmic grunting and heavy foot falls as he came went from exercise to exercise. I was in the corner of the gym resting between deadlift sets when he took the squat rack right next to me racking up hundred pound plat after hundred pound plate. After I stopped gawking I noticed he put the exact weight I was deadlifting onto the bar, I looked at his reflection in the mirror and met his gaze when he started his set. He did 20 reps with perfect form and no signs of effort as he didn't break eye contact the entire set. My new personal best of a single deadlift at 600lbs felt like I may as well have lifted a tenth of that.
I couldn't help myself as a nice sized tent sprouted in my shorts which he noticed and gave me a smirk before doing another set of 20 reps. I took my time to calm down and resume my workout doing my best to ignore him as he kept squatting and adding yet more plates with little more exertion every set. He soon had the bar maxed out with hundred pound plates and seemed to be either waiting for something or possibly taking a break before resumed. I sat down on a nearby bench to rest briefly after putting my weights away when he quickly took his spot back and resumed squatting. I had a front row seat to watch as he slowly and easily squatted down nearly till his ass touched the ground and stood up grunting under the exertion and displaying his prowess. His ass looked two basketballs cut in half stuffed into blue spandex, balls bigger than any NBA player could hope to hold without two hands cupping their massiveness. As he squatted down I got so hard that I couldn't tell what had more blood in it, my entire body after a grueling deadlift personal record or my dick. He did a full ten reps with a familiarity like meeting a lifelong friend before he reracked the weights with a very loud and echoing thud, further driving home how empty the gym was with only the two of us there.
He turned around and sauntered/waddled toward my slack jawed self. His legs were so pumped they looked like a chart of the human circulatory system through his leggings; but what drew my attention the most was the mass at eye level that was not dissimilar to a fruit arrangement with two grapefruits and a thick bottle gourd but with angry thick veins everywhere. As it throbbed and pulsed with a large wet spot forming on the tip I heard him speak for the first time tonight. "Hey, my eyes are up here mate.” he said with a voice as deep and gravely as a mountain slide, "Can you do me a favor bud and rerack my weights? I got something I need to take care of as you can see." He chuckled to himself as he gave his dick a squeeze eliciting a groan from the both of us and made the wet spot on his spandex expand further. I nodded as he put a very heavy and calloused hand on my shoulder. "Thanks a lot man, nice work on the deadlifts bud." He took his hand off my shoulder to close my mouth which I hadn't noticed was still open as I stared in disbelief. He winked at me as he waddled away. I felt like I was about to cum then and there as he slowly made his way to the locker room taking enough time to make sure he had my undivided attention. I awkwardly stood up as my dick was so hard it hurt now and put his weights away. I just couldn't help myself to do what he asked and someone has to do it right?
I spent the next few minutes stretching with my erection refusing to get less hard before I headed to the locker room as well. I was debating if he was coming onto me, toying with me, or just got off on showing his power when I heard the telltale wet noises of flesh on flesh and a very deep grunting coming from the stalls. I cautiously made my way towards the restroom trying my damnedest to not make my presence known when he started to moan loader. As I rounded the corner I could see his shoes in the stall closest to the door as he let out one last booming grunt. It took me a second to realize what happened as he came until I looked towards the ceiling; with an extremely percussive thwack he was hitting the ceiling tiles with such force to push them upwards. After what felt like a good two minutes his orgasm finally died down as he went from hitting the new hole in the ceiling, to over the stall door with a perfect arc to the mirror across the room, until finally it was contained in his stall. As my head was swimming in the miasma of his musk and the unadulterated rank smell of pure sex he let out a loud FUCK!
His feet were shifting and I noticed that strips of cloth were falling down to the ground, it took me a second to make the connection it was the remains of his wife beater. He continued to curse to himself with each word being muttered in a deeper voice while he stood up and, what I can only assume to be, struggled to pull his tights back up. I quietly slipped outside of the locker room before he could notice and waited until I heard his stall door to open before reentering, pretending I hadn't heard or seen anything. I went to my locker to rifle through my belongings as I built up the courage to say something, anything to him. As I was feigning interest at my gym bag I heard an extremely loud thunk coming from the weight scale, I turned around to see that he set it to max weight but with only one leg and part of his body weight had exceeded the limits of the now meager scale.
After this sunk in I finally took notice of him. He had grown, substantially, to the point that he far eclipsed the man who I saw in the gym earlier. His shoulders had grown so wide that even a set of double doors would soon give him issues. His thick neck had lost the lost not only the battle but the war to his encroaching traps that were now threatening to swallow his head. His back could rival the moon in its ability to eclipse the sun, thick enough that his arms were forced up further into the air. His arms, even at rest, were much thicker than either of our heads. Miraculously his leggings had somehow managed to not explode off of his legs that were now so massive he had to change his stance like he was straddling a Clydesdale stallion, and yet his calves were still grazing each other as he stood up straight. What both impressed and terrified me the most was that despite his immensity I could clearly see, with him standing the other direction, a few inches of his dick that was threatening to rip upwards through his leggings that are absolutely struggling to keep the monster caged.
He finally took notice of my meager presence, meager only while compared to him as otherwise my 6' 260lb frame would by no means be deigned as such. "Jeff right?" He inquired in a voice like the oncoming of a storm. "Yes actually, though I never got your name" I responded with my voice cracking in a combination of fear, lust, and awe. "I'm Ian." He replied with a hungry tone, "Would you mind helping me scrub my back in the shower? I seem to be having issues reaching it at the moment." He chuckled at his joke as he finally turned away from the weight scale he had been staring down.
I couldn't help but gasp as I saw him from the front after his recent changes. A chest so thick that light could not escape its crevices; his nipples were nearly forced into hiding as they pointed down towards the ground and his abs which looked like a vest network of deep canyons with 10 peaks. His ass was so thick that not even his quads could hide it as you could see the curves of it from his front. To top it all off was a bulge in the front nearing the size of a medium pumpkin holding his angry, veiny, throbbing nuts. His dick, which at this point was both longer and thicker than my own heavily worked forearms, was steadily dripping precum through his straining tights.
I have to admit I'm it proud of it, though I dare you to do better in my situation, but I came right then and there. I had always been the bigger man in my relationships, I was rarely outsized in my day to day interactions, but to come face to face with so much...man was too much for me. A man who, with a conservative estimate, was well over twice my size yet only an inch or two taller released a flood gate from within me that seemed like it wouldn't stop nor did I want it to either. He waddled over to me and put hands that could easily envelop my thick shoulders to support me. "Whoa there Jeff, I take it you like what you see eh?" He said while laughing. My dick gave an appreciative spurt as my orgasm started to end. "Guess you need a shower too now don't you bud?" He chortled. I numbly nodded my head while drinking in how close I was to this demigod. As he kicked off his shoes he instructed me to go ahead and strip then head towards the shower with him. He waddled away slowly taking every step deliberately while flexing his legs and ass as I took off my sweaty cum drenched clothing as if my life depended on it.
I caught up with Ian in the room before the showers which had a large mirror and counter spanning the length of the wall. Ian was performing pose after pose with a combination of both worry and pride. While still looking into the mirror he met my gaze mid side bicep pose. "Fuck Jeff that is a nice piece you have their man! Though, not quite nice as mine heh". I couldn't help but blush; imagine a stud like me reduced to blushing like a school girl, as I flexed my 10" dick at him with my golf ball sized testicles bouncing. "Well Ian we can't all be freaks like you can we? What the fuck are you on that is making you grow like this and where the fuck can I get some?" "Never mind that Jeff, have any critiques on my posing stud?" He transition to a most muscular as he said this. A pose had never before lived up to its name until right then. He waddled over to me and flexed his arm which as pumped as it was had to be nearly twice as the size of his head now. "Or would you rather just feel it?" I gulped and slowly put my hand on the fire hot, harder than diamond bicep and came all over his leggings and stomach. Ian started laughing as he stopped flexing his arm, his dick now drooling a steady amount of pre through his tights, and swapped back to a most muscular.
All the veins on his body were in stark relief as his head was being consumed by his chest and shoulders mid flex. "You do know you're going to have to clean that up right?" He said as he stopped flexing and stood up straight. I finally ended my second orgasm within a few minutes of each other as he stared into my soul. He started bouncing his pecs which at the point was akin to a devastating earthquake with his mass. I reached out and placed my hand firmly on his chest as he was doing this. Ian's dick throbbed and let loose another salvo of pre as he kept bouncing his chest with my hand firmly on it. I slowly brought my hand down his chest committing every part of it to memory for future alone time material. I got near his nipple and gave it a nice hard squeeze not realizing what hell would break loose.
Simultaneously a few things happened. 1) Ian's eyes bugged out as he let out a combination yell/moan. 2) His knees started to buckle as he leaned forward putting enough weight on me for support that it made me worry that my own strength was being put to the ultimate test. 3) His dick throbbed torturously as he came with such force that despite his leggings it rebounded onto my legs from the wall a few feet away from us to the point it stung. 4) As he was thrusting his hips like a man in a seizure he grew, God did he grow. Ian bellowed out a very drawn out and angry FUCK as he curled his toes as if he was trying to claw into the earth. While mumbling/moaning incoherently he drew me into a bear hug to support his still thrusting and cumming self. He was radiating heat to the point I worried I was going to be burned as he inexplicably ab fucked my dick with his thrusts. I couldn't breath and when I could all I drew in was more of his heady musk. I joined him in my third orgasm in less than twenty minutes making an even worse mess over his stomach.
After what felt like a sweaty crushing eternity he finally dropped me to the ground. I looked up but could only see his immense bulge and chest, his face long hidden by the two. "God fucking damn it!" He roared as he awkwardly waddled to the mirror. I stood up as he was examined himself with a mixture of expletives and curses at me and his luck. His arms were nearly locked into place at a 70° angle, each nearly as thick as my chest. Ian grunted in pain as he vainly grabbed towards his tights that somehow had still not burst off of his indescribable bulk, I really need to write a glowing review for the company that made them. I noticed his source of discomfort; his tights were now past skin tight and were digging deep into his rock hard flesh. Through a hole which had torn open on the back side I not only found out he chose to go commando tonight but got a full on view of his shaved hole. I stepped closer to Ian as he awkwardly tried to maneuver his bulk to a point where he could grab his tights and either take or rip them off. Defying logic he somehow gained purchase while awkwardly bending down as much as his body would now allow. As he got his leggings down to his knees he thrust backward with enough force to impale himself half way onto my 10" dick much to my delight and his horror.
"JEFF WHAT THE FUCK MAN!?!" Ian screamed as he instinctively both clenched and stood up with enough force to bring me with him. With me still half way into his medicine ball sized cheeks Ian struggled to reach me but his new bulk interfered with his every movement. "Jeff get the fuck out of-" I couldn't help myself as I buried myself to the hilt. Ian let out a deep and angry moan as I started to thrust. "Jeff you mother fucker, when I get my hands onto you I'll show you how a real man does it you bitch!" I responded by pulling out to the tip of my head and slamming down to my bush as hard as I could, repeatedly. Though I couldn't see it, Ian's eyes rolled back up into his head as he bent forward trying to get support on the counter despite himself. As I kept deep dicking the big bitch I heard the telltale heavy sound of flesh hitting flesh as his massive dick was forcibly hitting the middle of his chest in rhythm to my thrusts. I couldn't see Ian's face, or anything in asides from his back for that matter due to it taking up my entire field of vision, but I could imagine what his sweaty face looked like as he became the bottom I fucking was making him.
Eventually I no longer heard the sound of his dick bouncing off his chest but heard a gulping noise as Ian started to suck his down his own cock. Apparently he was too much man even for himself as I heard him gag every time I thrust forward and drove his dick further down his throat. Ian soon started to clench his massive ass and flexed it as hard as he could which I can only assume meant he was close to cumming, but then again so was I. Even with all of his strength he wasn't able to stop me completely as I redoubled my efforts on him. Soon I heard Ian swallowing as he started to grunt in worry and confusion as he came down his throat which began his next round of growth. His rhythmic clenching and vice like grip spurned me into cumming as well as keeping me inside him despite his wishes. Ian was forced to stand up as his arms were raised to parallel of the ground by his ballooning chest and widening back. His head was locked into place by his shoulders and chest as his dick kept up with his growing muscle at a neck break speed. Ian could see each volley travel up the multiple feet of his dick which was quite firmly stuck in his mouth. He was forced to swallow more and more as his balls tensed up and then expanded lower with each blast. Ian attempted to turn around and dislodge both me from his rear and his own convulsing dick from his mouth but was immediately tripped by his tights still wrapped around his knees.
We both fell to the ground with a noise that echoed through the entire building, I was violently driven forward until I was fully impaling Ian's still bucking ass. I put my hands on his back, the only thing I could reach now to stabilize myself, as I emptied my soul into his innards. The fall finally dislodged Ian's angry dick from his mouth which continued to expel everything it had into the next room. I soon stopped my fourth outburst of the night and slowly disentangled myself from Ian. He was still cumming and growing but was finally tapering off as I stood up. I saw the mess I made leaking out of his cavernous ass crack onto his legs which were now thick enough that the only space between them was a small area where the knees met. Ian was still humping, as well as he could in his situation, with his tights now around his ankles just above his kicking socked feet. (I REALLY need to invest in a pair of those). I made my way to his front relishing every second of his size and the afterglow of the best sex I'm sure either of us have ever had. As I finally got to his head he let out one last volley a good foot out of his dick and slowly stopped growing. Ian was now so large that every limb was locked in stasis. He wasn't going to be leaving the building let alone moving without a great deal of assistance now. I can only guess that his drinking his own cum made the growth affect him so much more this time.
I grabbed Ian's head by his hair at least as much as his neck and traps would allow me to. His cum covered face was barely coherent after his ordeal. I bent down and gave him a deep kiss before licking off all the cum left over from his face. A few seconds later my dick let out my fifth, and most massive, orgasm of the night all over Ian's head as I gained approximately 10lbs of muscle and 2" to my jumping cock. As I came off my growth high (God and that's only a fraction of what he felt and gained!) I asked Ian a few questions. Who was your supplier and who do you want me to get to help you? Both answers were Mike the gym owner, just like I thought. Do you have any more left? His locker was his response; I looked over into the lock room with the only door open asides from mine which had his gym bag poking out of it. With a smile I dropped his head which slumped back down onto his still hard and leaking dick. I made my way over to his locker and found both his cell phone and the mystery supplement. As I read the instructions, to avoid becoming just like Ian, I texted Mike from Ian's cell phone. I gave myself my first dose of the supplement, and new life, and felt even more exhilarated and energetic. I'm going to go do one hell of a fucking work out until Mike shows up at opening in a few hours, but for now I think Ian is ready for round two. I know I fucking am.
