The neon lights suddenly turned on, revealing two women in the middle of a large room packed with all kinds of massive weightlifting machines and equipment. They were both between 20 and 30 years of age. One was blonde and the other was a brunette. Both of them were pretty average in every way, neither beautiful nor ugly, neither skinny nor fat. They both had a metallic collar around their necks, the blonde one with the number 52 and the brunette with number 53. Neither of them knew and what happened to them or how they got there. They didn’t even know each other. They were both laying unconscious in the middle of the large, hangar-looking room. There were no windows and only a single large metal door. After the room got lit properly, a loud buzzing sound coming from a large speaker mounted on the wall could be heard, snapping them back to reality. A few seconds later a manly voice could be heard. “Welcome! Welcome to my humble enhancement room! You must be wondering why you’re here, right? Well, to be completely honest, that’s pure chance. You see, I’ve always liked to let fate decide the next girl I kidnap in order to help me out with my wonderful “project”. This time I decided it would be fun to go with 2 at a time. But first, let me show you what I’m talking about.” the voice said confidently as the man behind it pressed a button next to the microphone. The speaker buzzed again and the huge metal door unlocked itself. It took a while for it to open because of its imposing size and weight.

After the metal door completely opened, a massive humanoid being could be seen in the shadow of the other room as it started making her way towards the two girls. Both of them were visibly frightened by what they saw next, to the point that they almost pissed themselves. They didn’t expect to see anything like this in their lifetime. A literal wall of muscles that barely could be called a “girl” stood before them, tall enough that they barely reached her enormous chest. Her arms were rippling with thick, dense muscles, nearly as wide as the two women’s torsos. Her biceps and triceps were both bigger than basketballs. Every thick slab of muscle was bulging intensely with intoxicating power. Her upper torso was wider than the two girls put together, a sharp contrast to her much thinner waist. Still, her midsection was definitely wider than a normal man’s shoulder width. She had the most chiseled six-pack the girls had ever seen, with deep crevices and wide rippling abs that twitched with every breath she took. Her muscular hips were incredibly large too, sustaining the boulder-sized glutes that looked to be able to literally crush bricks between them with ease. Her legs were just as ludicrously large and freaky as her enormous arms. Her rock-solid thighs were nearly as thick as the trunk of an old tree and her calves just as big and imposing as actual cannonballs. They could barely see her face from where they stood as it was partially hidden behind two immense slabs of beef that were her bulging pecs. Each vein-riddled pectoral muscle was much bigger than her head and even bigger than ripe watermelons. It was clear that she had little to no fat left as her breasts now fully consisted of pure muscle mass. Her nipples were always hard and lewdly pointing towards the ground because of the insane size of her pecs. The only things that could clearly be seen above her chest were her long brown hair and dark brown eyes.

“Isn’t she marvelous?” the voice on the speaker said to the completely speechless girls. The musclebound monster blinked a few times and leaned forward to get a good look at the insignificant beings below. She was completely naked, allowing every inch of her extremely muscular frame to shine in the neon light. Her muscles strained audibly with the slightest movement she made. The frightened women observed that she had two small tattoos on her humongous pecs. The one on the left pec read “ANN” and the other one read “SLAVE”. The girls immediately understood that Ann was her name and the other tattoo meant she was got kidnapped a long time ago and turned into this monstrosity. “Show them what you’re capable of, my dear.” the voice said with clear excitement. Ann complied without uttering a single word. She began flexing her muscles, starting with a spectacular double biceps pose. Both of her biceps effectively doubled in mass, adding ludicrous amounts of hard beef to their already extreme size and muscle density. New monstrous veins appeared and the old ones thickened further until they were about the size of regular human fingers. No normal being was supposed to have biceps this huge, but there she was, in all her naked glory, breaking all the limits of human anatomy. Her lats bulged wildly too, greatly increasing their original size and giving the impression that her torso had broadened as well. The strange thing was that they stayed that way even after she relaxed her muscles.

The massive woman then turned around and did the same pose, but this time focusing on her massive traps and sprawling backside. Her back muscles exploded with size, pushing her traps higher as her biceps grew yet again, becoming solid masses of hard meat that could crush cinder blocks between them and her freakishly large forearms. She put her huge hands on her hips and flexed her lower body next, pumping her thighs bigger than any male torso, making obscenely thick veins appear all over her gargantuan legs. The blonde wondered for a moment if she could even wrap her arms around one of those powerful pillars of meat. That was before she noticed that the muscular behemoth was casting an even larger shadow now, much to her disbelief. Her muscles were simply not going back to their relaxed state, even a few minutes after she stopped flexing them. If she kept going like this, she would go from a brick wall to fortress wall in no time. The beast’s width, height and muscle density were simply off the charts by any standards, no matter how extreme. “Yes!! Harder! Flex harder and grow for me!!” the voice said, this time clearly aroused by Ann’s display of size and power. The girls wanted to scream for help, but were simply unable to. Their eyes were simply glued to the throbbing mound of hard muscle mass before them. They just couldn’t believe such a being was real. And the fact that she was once a normal girl was also near impossible to comprehend. Ann kept flexing her massive muscles, going from side chest to most muscular, then from lat spread to side triceps, pushing them from every angle to make them grow bigger. Every inch of her body screamed power and dominance. She was growing everywhere you looked, making her previous form look small by comparison.

By the time Ann stopped posing she stood nearly 50% larger than before. Her beefy pecs had almost tripled in size, becoming so big they could easily crush bowling balls between them. Her shoulders had broadened to be able to support her much bigger back muscles, with her traps now reaching the halfway point of her head. Her biceps were so big they put actual boulders to shame, while her immense triceps perfectly complemented their cousins’ ridiculous sizes. Her arm alone was two times bigger than the two puny girls put together. Her torso thickened as well, gaining another pair of impossibly huge abdominals and turning into a mind-bending 8-pack. The girls couldn’t believe their eyes. She actually managed to flex so hard that she pushed another set of abs out. Her hips expanded further, now supporting a huge pair of glutes that shamelessly emphasized her small and tight pussy. Her asshole couldn’t even be seen as her muscular buttcheeks had no gap between them. They were pressing against each other so hard one would need a jack to be able to spread them apart. A small waterfall of womanly juice could be seen trickling down from between her gigantic legs. “It seems she got really excited after all that flexing. Well, can’t blame her, I loved it too! Now that brings us to why you’re here. I’ll try to keep it as short as possible: you’re here to serve my lovely Ann. Her only goal in this life is to get bigger and freakier for my own desire. Of course this wasn’t always her objective, but ever since I implanted that small device into her brain, she’s never disobeyed my orders. So you girls are here to make sure she’s properly fed, cleaned up and always pumped full of roids. Oh fuck I just can’t get enough of her! Such a shame this pumped up state withers away after 10 or so minutes. But we’ll fix that. We’ll get her so big and hot she’ll not even be able to flex anymore. Just the thought of it makes my cock even more painfully hard!” the voice said between heavy breaths. Wherever the man who was speaking was, he was definitely stroking his cock.

“By the way, you can call me “master”. I like how it sounds!” the man added after a few seconds of silence. The speaker then buzzed again and a trapdoor opened behind the two women. A sturdy metal box that contained various items entered the room via an underground raising platform. Inside it they found towels, bottles of water, soap, protein bars and most importantly, dozens syringes filled with the most potent steroid one could find on the black market. “You got what you need. Now get to work, slave! Start pumping those muscles before you go back to your smaller self!” the master said as he continued to jerk off. Ann started walking towards one of the cable machines, disturbingly thick veins already pulsing across her rippling body with frightening intensity. Even totally relaxed she looked like she was flexing her brains out and was on the verge of bursting out of her own skin. She was showcasing such extreme definition it was simply ridiculous. But the true madness was only getting started. Ann set the cable machine for overhead triceps extensions and started pumping out grueling rep after grueling rep. The amount of weight she was using was breathtaking. The two servants couldn’t even properly read the number of pounds Ann was pumping like the muscled beast she was. It wasn’t long until she began to sweat profusely. Even though she was struggling, she didn’t say a single word. The only sounds she made were grunts and occasional moans. She shuddered with pleasure as she felt the cable caressing the deep fissure separating her mountainous, oversized traps. With each rep her muscles burned and exploded with new mass, ballooning to unnaturally huge proportions that made the girl’s jaws drop once again. “Oh fuck your traps are so huge… And those arms are so fucking loaded with muscle… FUUUUUCK!! MORE!!!” the master groaned as Ann continued her reps, the inhumanly dense muscles of her back bulging outward with countless overdeveloped ridges and mounds of freakish mass. Her hulking triceps surged powerfully against her already stretched out skin as she moved the massive weights again and again. “GIVE HER 2 SHOTS! MAKE HER GROW!! OH FUCK!!” the master shouted as he got closer to busting a nut. The girls picked up one syringe each and injected the massive woman with 2 large doses of potent steroid directly into her butt. Ann grunted as she felt the marvelous liquid entering her system, making her already colossal triceps swell again. With each passing second, the back of her arms got stuffed to the brim with even more rippling bulk while her pussy created a small pond around her colossal legs. The muscle-building liquid did wonders to fuel her gargantuan physique and make it develop further. Ann could be heard moaning as she finally dropped the cables, letting the huge weight drop to the floor with a loud thud.

“Let’s do legs next!” the master said, still stroking his hard member. But first, he ordered the servants to clean up the sweat from Ann’s body. They grabbed the towels and started wiping Ann’s insane muscles, making sure to get her nice and clean for what comes next. They couldn’t believe how hard her body was. Her muscles felt like they were made of granite. This wasn’t a human being anymore. Ann was a freak of nature. Even her sweat smelled like the steroids she had going through her entire body. Her sweat was so abundant it could easily fill a few buckets. There was so much it rendered  the towels useless after the servants were done cleaning her up. “Go on, my dear! Start pumping those legs like a good girl!!” the master ordered. Ann settled in the leg press machine, involuntarily flexing her monstrous arms as she grabbed the handles, causing her freakish vascularity to pulse lewdly. She released the colossal weights against her legs and bent them as much as her insane muscularity would allow. Her hulking thighs were pressing against her gigantic pecs and her meaty calves were touching her overdeveloped hamstrings. With animalistic determination, Ann straightened her muscle-packed legs and pressed the weights upward, groaning slightly as she heard her skin stretching. She was forced to spread her legs apart further as the muscles of her inner thighs were squeezing against each other, as well and preventing her from completing the reps. Not only that, but doing the exercise like this meant her drenched pussy wound get even more aroused and dump an even bigger river of roided up pussy juice onto her head, possibly drowning her in her own bodily fluid.

“Oh fuck yeah!! Check out those big bulging legs!! I love them!!” the master exclaimed as his muscular behemoth powered out another rep, feeling her humongous quads erupt with new and impossibly shredded mass. “BIGGER THAN TREE TRUNKS!! MAKE THEM BIGGER!!” he yelled with excitement. Her thighs flared wider and fuller, the bulging muscles expanding and pressing against the metal rails of the leg press machine. Ann forced out rep after rep, feeling her disgustingly overdeveloped quads pulsing with an extreme overabundance of steel-hard muscle fibers. Her roided up slabs of beef were rippling beneath her paper-thin skin as they overcame the increasing resistance of the giant weight. “MORE WEIGHT!! I’LL MAKE YOU BIGGER!! I WANT YOU TO BE THE BIGGEST MUSCLE FREAK EVER!!” the master screamed into the microphone as he pressed a button that made two more enormous plates to drop on the already ridiculous pile Ann was pressing. Ann couldn't see her own beef-stuffed legs beneath her absurdly massive pecs, but she could definitely feel her extreme muscles fighting for space as they grew. New and thicker veins surged all over her massive quads as her tree-shaming legs were being forced apart little by little with every rep. Ann’s entire body was covered with sweat and pussy juice, but even with the added weight she kept going. She squeezed the handles of the leg press with monstrous intensity, bending them both as she continued to brace herself for yet another agonizing rep. “COME ON!! 10 MORE!! I’M SO FUCKING CLOSE…” the master ordered as the beastly woman forced out another grueling rep. The leg press started to creak as the overpumped legs of Ann continued to push and grow. The women were moments away from fainting as they saw Ann’s legs on the verge of breaking the machine with their godlike strength. “ONE MORE SHOT!! NOW!!” the master ordered. The blonde rushed to grab a syringe and immediately dumped its contents into Ann’s vein-filled quad. She grunted like a wild animal then immediately pushed the weight back up. Without saying another word, the master dumped another steel plate, making Ann’s last 3 reps even harder. But the monster woman wasn’t gonna fail her master at this point. She clenched her teeth and started pushing like never before. Getting a much needed boost from the last dose of roids she did 2 more reps and came down to the last one. Her legs were red hot and the veins on them were ready to burst. With a primal roar, Ann flexed her entire body and finished the last rep, her pussy erupting with a powerful jet of warm juice as she did so. Not only did she finish the rep, but the last burst of power from her legs was so intense it detached the massive weight from the machine and hurled it against the nearby wall, completely destroying it. Even though there was no sound coming from the speaker, the master definitely came harder than ever before after such a breathtaking display of raw power.

The girls saw the massive hole in the wall as their ticket to freedom so they decided to make a run for it. After only 20 or so steps though, the speaker buzzed again. “Where the hell do you think you’re going? Are you seriously trying to run away? Well, go right ahead! But just so you know: those collars aren’t just for show. If you get more than 200 feet away from the center of the room, the collars go boom! So why don’t you turn back like the good servants you are and start taking care of my wonderful Ann? She’s such a good girl. I came so hard I almost lost my mind.” the master said with authority. The two women didn’t know if he was telling the truth or not, but the fact that the collars started beeping the farther away they got really got them worried. Maybe the madman was telling the truth. They weren’t willing to take that chance. They turned around and started walking towards the musclebound behemoth, visibly upset by their failure to escape. They thought nothing could surprise them anymore after spending the last hour or so with Ann, but they were mistaken. After such a brutal workout anyone would be completely spent, but not Ann. The muscle monster was back at it, doing bicep curls with the biggest dumbbells ever conceived. Those things were so heavy they required 5 grown men in order to lift them, but Ann had one in each hand and did rep after rep with them and not showing any sign of stopping soon. Her biceps surged like colossal mountains of muscle, her skin audibly stretching as it struggled to accommodate the growing slabs of beef. Her already swollen veins were pulsing intensely across her hulking biceps and monstrous forearms, feeding more roided up blood to her ridiculously huge arms. She kept curling the enormous dumbbells until her bulging forearms met her massive biceps, the steroid-fueled muscles filling all the available space on her arms and peaking near her fists, preventing her from fully bending her arms. Ann was covered from head to toe in a lewd mix of sweat and her own pussy juice. The image of her doing bicep curls with ridiculously large weights made the girls realize that this was their life now. They were no more than servants to this monster’s needs and her master’s desire to see her grow even more. “Give her another dose of juice! Then clean her up as soon as she’s done pumping those beautiful biceps! Fuck, my cock’s getting hard again! This is gonna be a long day… and I’m gonna enjoy every second of it!” the master said as he started stroking his cock again.
