Carly's body was on fire, another two reps and she’d have beaten her personal best of 10 reps with 10lbs. Her tiny frame was glistening with sweat, brow furrowed in concentration. Her small curves and body nestled into the tight confines of black leggings and a tight sports bra. She had been coming to this gym for the past month, attempting to bolster her smaller figure, hoping to build a slightly, thicker body. Has her small biceps heaved with effort to lift the 10 lb up to her chest. She hoisted and let out a sigh as the weight connected with body, the cool metal feeling flush against her sweaty body. Carly let the weight fall back to the bench, she leaned over, puffing at the physicality of it.
By all accounts, Carly was a beautiful woman, lean body with no curves to speak of, she stood about 5 '4 and weighed a little over 110 lb. She was a book nerd, and usually hidden under layers of sweaters and leggings. The gym was a new experience for her. She was intimidated in the locker room by the strong female figures, with thick muscles, or toned glutes, figures that filled out spandex and left her body flush when they undressed for the shower. She tried not to stare at the bulging muscles on some of the men, how their veins popped out when they lifted the weights, or how their calf muscles flexed every time they went into a squat. Secretly, Carly had been checking out every single person who went to the gym, male or female. She wasn't sure how so many attractive people all worked out in the same space. And how despite the growing throng of grade A gym meat, all of the other guests could seemingly workout without staring at the sexy and defined bodies all around them.
As she sat there wheezing, wondering if she should try another set, one of the trainers walked up. He was a tall handsome man, with a deep tan and a set of abs that you can see through his shirt. Carly thought his name was Lance or something. He usually checked people in at thr front desk, sort of the eye candy to get new people into the gym. He'd been nice to her the few times he had checked her in. “ Hey Carly, how's the set going? Looks like you're pushing for a PR?” He winked at her playfully as he walked up.
Carly wasn't sure how Brandon could have possibly known that, but she was excited that she was getting recognized in the gym. “ Yeah, it's been a lot of work to get to this point. But, these muscles won't build themselves” she said, attempting to wipe sweat from her brow, returning the smile (albeit a bit thrown off by the wink). Good convo. She thought, now he's really going to think you're an introvert. Carly blushed furiously. Brandon simply smiled, “Well the work is really showing, look at that bicep!" His hand wrapped around her tiny muscle and gripped lightly attempting to show off her tiny arm. "A little muscle looks good on you. Hey, by the way, we're offering free samples of the new improved Mass Muscle Maxxx.” Brandon brought out a sealed plastic baggie with some powder in it. “You can just add it to your shaker, and it's been shown to quickly improve muscle mass and drive.” He flexed his thick arms right in front of her when he finished. Carly's eyes drank in every pulsing vein, her mouth was open and nearly drooling as he smiled and winked at her again. “It really did wonders for me, I was almost as small as you are before I started taking it” Carly found it hard to believe that Brandon was ever small. Even staring at him. His arms were impressive, his legs tree trunks of muscle, but under all that she could see the thick bulge of his cock underneath his spandex shorts. Everything about him was big. As his hands dwarfed her own as he handed her the baggie of mysterious protein. “Let me know what you think, I know you'll enjoy the results” Brandon's hands slid off of Carly's arm almost lingering for a moment, as he smiled coyly and headed back to the front desk. Carly watched as his perfectly toned ass strutted away from her, wiggling in the compact spandex that showed off his every flex. Carly, looked over her shoulder into the mirror, staring at her flat ass in the tight black leggings and sighed.
Carly had never taken protein, I mean the idea was there, but what would she be adding too. She looked at herself in the mirror, sweaty and thin, sports bra flat against her tits, the barest hint of nipple poking out. Trying to imagine Brandon's frame closer to hers, how could his frame be anywhere close to the size of hers ever. He could absolutely dwarf her, pick her up and do what he wanted to her, the thought made her gulp and shove down a wave of arousal. She looked down at the protein in her hand, and decided to dump a bit of it into her shaker. As her lips tasted the sweet protein laced water, she realized she had a little bit more gas in the tank. She gulped down a few quick swigs, picked up the 10lb weights and proceeded to do another set of reps. It felt good, maybe it was the praise from Brandon, or the fact that she had the protein, but the weights felt easier than before. She racked out a few more reps quickly and took a few more swigs of the delicious drink. The more she drank, the more she felt she could keep going. Despite finishing a nice arm work out, Carly felt like doing some squats, working to eventually pop her booty out a little bit, maybe Brandon would notice, or anyone in this gym. She put the weights away admiring the thick definition coming into her arms. Her chest was already looking a bit thicker as she flexed at her reflection in the mirror. She knew there was no way, but she swore she saw a bit more muscle defining her top, now a bit stretched from her intense arm work out.
Carly was envious of all the gym girls with the thick glutes that caused their leggings to pull taught. She had more than once starred wide eyed as one of the many hotties had bent over, or squatting down, legs tight and ass a perfect bubble behind them, out on the floor or in the locker room, wiggling to peel off the skin tight leggings, watching as inch after inch of ass bounded out of the enclosed prisons of fabric. Carly was surprised more women didn't rip their leggings with the amount of ass shoved in the synthetic clothing at this gym, it seemed every woman (and half the men) had a thick bubble waiting to rip free of the tight space. She felt her own pussy and legs begin to boil away with need and lust, just thinking about the packed muscles locked in tight to their fabric prisons. Half ass cheeks out, or people adjusting themselves sweaty and panting. How she started trying to trace the lines of women's thongs, and men's cocks in each mirror as she wandered over to the squat bar, huffing and sucking down more and more of her protein powder. It felt like liquid gold going down her throat, and she had to stop and fill up the water bottle again to finish off the last of the powder. Carly adjusted her top, which had been creeping down her chest as she sauntered towards her goal.
Luckily the squat rack was open, the previous thick gym bro had just finished putting away the weights and had left the space open. He huffed and flexed in the mirror as he cleaned up, Carly watched as she walked up, noting his fine physic and drooling over the peaking out six-pack from under his shirt. She walked over to the bro, slapped him on his thick ass and winked. “Nice set” she blurted out, as she cooly attempted to walk past the behemoth of a man, unbelieving what she had just done. She didn’t know this man, let alone thought she could get away with slapping his ass. The man was confused at first, but then drank in Carly’s figure as she walked by and began lifting up her weights. Taking a long look up and down staring at the book nerd with a deep ravenous lust, he then merely flexed at her with his massive pecs before turning around and walking towards another area of the gym. What had he seen, Carly wondered as she smiled back and felt herself go flush.
Carly walked over, sipping down more of the protein. She adjusted her stance and picked out a wedgie that had been creeping up since she had slapped the bro’s ass, and had somehow found its way between her pumped up cheeks, before setting 55lbs on the bar to squat. Carly had never done more than half her body weight before and was slightly nervous to get under the bar. But, as she leaned down and got in position she was shocked to find the bar felt lighter than ever before. The power behind her legs felt incredible as she flexed and began her reps. It was easy, and every dip felt like ecstacy. Her legs felt powerful, and as she stared at herself lifting the weight over and over she was surprised to see her body thickening out before her eyes. Her calves had begun to bulge out within her leggings, forming tight tapering at her ankles before ballooning out up towards her thickening thighs. Before today, the leggings Carly wore would have been best defined as loose. Now the thighs pressing out in all directions were causing the dark material to lighten and grow more and more transparent. Carly’s pussy was now outlined thick and puffy between the swelling thighs and she could begin to see the outline of her thong wedging itself up inside of her. With every dip she could feel her clothing pressing against her clit, and it made her want to keep going, to keep growing. Her ass was pumping out in thick pumps as she continued to rock rep after rep under the bar. The tight fabric left little to the imagination of the rest of the gym, and Carly was surprised to notice a few members checking her out as she bounced up from another rep, her ass lightly clapping for the first time in her life. She grunted watching in fixed horror and erotic fantasy as she watched the mirror reflection of herself put on pound after pound of thick muscle. She racked the weight after a few dozen reps and picked up another 45lb plate and added it to each side. As she did, she watched her phat backside wobble back and forth, muscle under marbled toned ass cheeks. “What is happening to me?” she said outloud before uncapping the shaker bottle and taking a long pull from the bottle. The merest feeling of fatigue floated away as Carly felt more and more power build inside of her. She quickly got back under the newly weighted down bar and hefted the weight up easily.
As Carly dropped down she felt the rip of her tiny spandex, there was just no way at this point the confined prison could hold this much weight. Carly’s thick ass wobbled as she dropped down in a perfect squat. The sheer meat wobbling behind her as she settled in left her oogling herself, she saw the dripping wet thong, now wedged so far up her pussy she could see the marble sized clit protruding from the fabric like a fucking button. Carly hefted with all her new strength and launched the weight back up and down, her ass cheeks clapping as she dropped 20 reps in rapid fashion, moaning and sputtering at her own body. Each rep felt like a mini orgasam, her body swelled out thicker and thicker, legs like tree trunks, and an ass that was quickly thickening out to Brazilian butt lift territory. She grunted and moaned as she let the last rep slam into the rack. She huffed and pulled herself out from underneath the bar and stood to her full height. Carly looked down at her new form. She flexed her new lower half and smiled at the curvaceous but powerful new figure. She was lost in the mirror, staring at herself flexing her lower half, when Brandon walked up to her a bit chagrined. “Carly, umm, damn that new protein might be working a little too well. Umm, we do usually require our members to wear…..some sort of leggings? I don’t think that thong is going to cut it.” He tried to sound humorous, but Carly, could tell he was staring at her bodacious bottom half, and trying to keep the creeping head of his massive cock from sliding down the bottom of his shorts.
“You’re right. You should give me your pair. They might just fit me now” Carly said with little thought. She turned to face Brandon. Which only seemed to increase the throbbing erections girth more quickly. Her body was that of a cross between a powerlifter and a ballet/hip-hop dancer more ass than anything and with a dripping wet chunky cunt on full display. “Umm, what….” Sputtered Brandon. That was all the words he could sputter out before Carly moved over and pulled him closer in her arms. Her body wasn’t quite as tall as his was yet, but she was plenty strong enough to push Brandon against the mirrors and take down his shorts off, revealing the thickest dick Carly had ever seen, now bulging obscenely in tight briefs. The head was dripping precum in thick gouts as Carly removed his shorts and proceeded to manhandle his cock overtop his briefs. “Did this thick cock come about from this “protein” powder you're pushing?” She moaned as she stood back up and pulled Brandon's shorts over top of her ridiculous lower proportions. She hefted with immense effort Brandon’s shorts up, they left her ass barely half covered.
She shuffled in place as her ass meat wobbled back and forth as the tight shorts barely contained her now massive backside. Her pussy was fully outlined in the shorts, the lining barely dipping low enough down her thighs to cover her glistening pussy lips. She purred with power as Carly tapped Brandon's cock outline as she stood up and pecked him on the cheek. "Thanks Stud, come find me after my workout and we can put that protein to the test" as she waddled away.
Carly felt like lightning coursed through her veins as she took in the sea of flesh and muscles. Suddenly her confidence was skyrocketing in tandem with her libido. Men winked at her and flexed as she walked by, women were shy but still took in her visage as she waddled by hips swaying in the tiny shorts. She drank in their stares reveled in their lust. She blew kisses to some men, and shook her ass at some women as she bent over and filled up her water bottle using the last of the protein. As her lips drank the sweet draught she caught a look at herself in the mirrors. She was thick, a body like a divine pear, all thick ass and thighs, she marveled at the shift in size, smacked her own ass just to watch it wobble. Eliciting a light moan and purr. But, she needed to work on her top. Her tits had swelled a little, but hadn't kept up with her now impressive backside. She flexed her arms already twice as large as the twigs they were before. She licked her lips looking over the gym and landed on a stronger looking woman doing bench press. Carly walked over confidently and loomed over the women in her set. "Hello there, mind if I tag in with you" as she gazed over the chiselled woman's body. She was ripped and her abs peaked out from underneath her shirt as her arms pumped the weight up. Carly, grabbed the last rep of hers allowing Carly's body to squat down above the new woman's head giving her a great glimpse of her thick legs and pussy barely tucked behind Brandon’s old shorts as she hefted the weight up and reracked it. Without another word Carly gently shoved the stunned woman off the bench and got beneath the bar and strained. The weight was large, nearly a hundred pounds more than Cary had ever done, but as she felt the weight lift up off the bar, she could also feel the fire of the protein coursing through her veins. The woman Carly had bumped off watched in dumbstruck silence, as Carly's body began to pump up, her arms seemed to fill like water balloons with muscle, just adding itself on to her frame as she began reaping the weight faster and stronger. Carly's plump ass cushioned her as her upper body got more and more defined. Her tits once, small little blips of flesh, now began to rise like bread dough in their confined sports bra, more breasts swelled in all directions wrapped in her skin tight top. The woman attempted to help Carly with her last set. Carly was practically bouncing the weight off her new tits, with each rep her breasts grew larger, and the weight had to travel a little less down. Her nipples poked out as thick caps on the newly minted huge breasts protruding off Carl’ys impressive frame. The bar resting on chest before her last push made the massive amount of breast flesh poke out from all sides. As Carly hefted the last bar up the woman attempted to get her spot back. Carly barely felt the woman politely attempting to push her out of the way. She was too busy admiring her new body. Her breasts were massive, two huge globes of flesh pressed her sports bra to its limit. Her areola's spread far beyond the outlines of her sports bra, her nipples tented out the tight see through fabric. Her body was built like a shot putter, legs thick and powerful with a shelf of an ass behind her, which was eating up her booty shorts. Her arms and muscles were thick chorded and flexed with mean veins. She wrapped the annoying smaller woman in her powerful arms and began to kiss her and chuckle to herself. "You can have your spot back after you help me burn off a few extra bits of tension." She picked the woman up in front of the entire gym and placed her over her shoulder. Carly slapped the woman's ass in the mirror flexed and began to head to the showers, with her new fuck toy in tow.
Brandon had found some new shorts to wear and was still sporting a huge erection from the previous interaction. By the time he had found Carly to give her a piece of his mind, or maybe a piece of his cock, he hadn't decided which yet, she was already carrying around the new woman. "Brandon, Come now, I liked you better with less on" She purred at him as she walked right up to him. He was barely shorter than Carly now and a good bit less ripped. He had known the new experimental formalua he had given her was strong, but not nearly as strong as this. "Come on, I was just gunna shower off with this little treat, care to join us?" Carly reached down the shorts of Brandon and gripped his thick cock with her iron grip. With one hand on his cock, and the other grabbing the ass of the woman on her shoulder holding her in place, Carly dragged both victims into the shower with her.
Carly tore the clothing off of everyone she had in her hands, and turned on the hot showers in the woman's locker room. A few women had fled when Carly walked in, but a few others had stopped in the middle of getting undressed and stared at the lude display. Carly pushed the woman up against the wall of the shower, letting hot water drain over both as she began eating out the woman's pussy as she held her up in her powerful arms. She ravaged the womans pussy with her tongue and man handled her curves as she did so. The water glistened off her back, muscles dripping with water as it cascaded down her back and between her massive ass. She wobbled back and forth teasing Brandon standing behind her as she took the woman for every orgasm she was worth. Carly's muscles burned from her workout, but she had no problem pinning the woman beneath her massive frame. Brandon couldn't stop himself from coming up behind the goddess and plowing into her thick ass. He grunted as each inch went deeper and deeper. He could barely get his massive cock inside of her, there was a mountain of ass to work through. But, right as he felt the tip dip inside of her, Carly pushed back and shoved Brandon against the back of the shower. His cock quickly filled up every inch of Carly’s needy cunt as she groaned and grinded Brandon against the wall. Growling and howling in ecstacy Carly pinned Brandon with her now powerful ass and body, grabbed his hands and forced them to grope and grab at her massive tits. Her body was on fire, the water, the heat, the pleasure. Carly couldn't stand it as she moaned loudly, letting the last of the protein fill her out. She grabbed up the slut on the ground in front of her and shoved her face into her pussy. She could see her face getting bounced off the front of her cunt as she was pounded from behind. Carly had never felt so strong, or as horny as she was at this moment, and as her tight cunt began to feel the first pulses of Brandon's eruption of cum, she only thought of how to get more protein, before she began to black out from the pleasure.
By the time the cleaning night janitor had arrived on shift, he was surprised to see so many cars in the parking lot. He was even more surprised to hear moans and screams of pleasures coming from the woman's shower. As he turned the corner he was shocked to find a 7 foot tall Amazonian goddess fucking two men at once, while she ate out another woman between her hands. Her body massive compared to the others. There were bodies of used up sluts and himbos strewn about from a clearly many hour long sexathon. At least, they were in the shower he thought as the Goddess Carly looked him in the eyes between her tongue fucking he slut, and gestured for him to join in.
