He’d heard good things about the place, and when Kent sent him the referral with the special offer for a fifty percent discount on the first year of membership, how could he refuse?There were men of all sorts of builds and types. Big thick muscle men, hairy bears, bros, the works. The sizes ranged from big and bulky brawn to lean and tight muscle that focused more on acrobatics and cardio. Each of the men seemed to hold respect for the other, and there never seemed to be any negative feeling between them, despite the difference in styles and body types.Kevin looked down at the massive tank top that now swathed his frame. It seemed several sizes too large for him. His friend had promised he’d grow into it, and that it would become a favorite of his in time.“Ready to get swole, bro?” Kent grinned and flexed a vascular arm for his friend to view.“It’s not like I’m going to grow big overnight, Kent.” Kevin chuckled at his old friend’s exuberance. “Since when have you been so excited?”Kent huffed a deep chuckle. “Since I became a regular here. This place really knows how to help a guy blow up. It’s easy! You’ll see what I mean while we work out. Come on!The big man wrapped his hand around his friend’s wrist and dragged him onto the floor until they reached a segment of racks laden with various types of weights. He quickly seized a smaller kettlebell and shoved it into Kevin’s grip. Then he seized a far larger one for himself. Both were marked with the gym’s logo, a leaf bedecked with specks of dew.“Let’s start with some basics. These are called halos. They help to warm you up and loosen the joints.” He raised the kettlebell and seized the handle with both hands. “Raise it like this and circle it around your head while you stare ahead.”Kevin did as he was instructed.“Good. Good.” Kent smiled as the man got into it. “Let’s get started.” He whistled a familiar tune as they cycled rhythmically around their heads.“The mulberry bush? Really?” Kevin asked.Kent shrugged. “It’s got a good pace to it. It’s a trick one of my trainers here taught me when I was learning the ropes. A lot of nursery rhymes and their music make for great pacemakers when you’re working on sets. They sort of stick in your head after a while, and it’s so easy to come up with new lyrics for them, if you want to.“Like?”Kent smirked. “When we’re done with the warmup,” he promised.When they’d finished warming up, Kent nodded. “So, we’ll be doing some basic curls with the bells first. The song may be a little annoying, but once you let it stick in your head, it’s super easy to stick to the exercise. You ready, bro?”Kevin rolled his eyes. “Won’t you do it, even if I’m not?”Kent grinned, and the two began. When they’d reached a proper rhythm, the man began to sing in his deep bass.“Brawny, lift your kettle-arm.Brawny, lift your kettle-arm.Brawny, lift your kettle-arm.Fill out your muscle-tee.”“Seriously, man?” Kevin asked.Kent’s grin widened as he transitioned to his other arm and continued.“Dumbbell, switch your arm again.Dumbbell, switch your arm again.Dumbbell, switch your arm again.Pump muscle up today.”“You have got to be kidding me,” Kevin groused.“Dunno, I’d say it works pretty well, dumbbell.” He smirked and pointed to the mirror, where Kevin gaped at the sight of his other arm pumping the kettlebell.“… What the actual–?”Kent didn’t give him the chance to finish. He let out a deep husky chuckle and sang again.“Brawny, lift your kettle-arm.Brawny, lift your kettle-arm.Brawny, lift your kettle-arm.Fill out your muscle-tee.”“What’re you d-OING?” Kevin’s voice cracked as his chest surged outward and his neck thickened with corded muscle. His Adam’s apple throbbed and jutted forward as stubble prickled over his face. “Stop!” His eyes widened with fear as his pupils shrank with the impact of his adrenaline. His arm kept pumping. His shoulders heaved as he voiced his protest. All the while, his arms began to swell with every pump of the kettlebell. “Why can’t I stop? Why can’t I–ohhh, fuu–” His eyes rolled as his body was rocked by a shudder. He planted his legs at a masculine straddle while his calves and thighs swelled and his crotch inflated. “Wh-what did…? Bro, I … I….” He stared at his reflection. His mouth dropped open as his gaze became empty and glassy. “Uhhhhhhh….”Kent sneered as they lifted in time together, two men in perfect synch. His chest heaved with a deep chuckle. “That’s right, bro. Feels good, doesn’t it, dumbbell?”A dimwitted smile pulled at Kevin’s lips as swollen traps and pecs filled out the tank top. The stubble surged into a proper beard that blended seamlessly into the high and tight cut of his hair via carefully trimmed sideburns. He nodded as his head lolled and his arm continued to pump. The stamp at the base of the kettlebells seemed almost to glow as Kent resumed his song.“Dumbbell, switch your arm again.Dumbbell, switch your arm again.Dumbbell, switch your arm again.The meathead’s here to stay.”The drastically altered Kevin burst out with a deep booming guffaw. “Huhuhuh. Bro, you were totally right!” He swore in his exuberance. “That pump was fuckin’ sweet!”Kent grinned. “Wanna spot me on the rack, bro?”“Hell, yeah, bro!” The two broke out into a fit of laughter that rebounded through the gym as they returned their kettlebells to the racks and swaggered onto the main floor, where the barbells and other machines awaited them.——————————————————–From deep in the security room, a loud belch was followed by a sigh of satisfaction. A hulking brute of a man that barely fit into his uniform stared blankly at the screens while two clawed hands slowly massaged his temples. Silver trickles flowed into the fingers as tiny nubs slowly began to push on either side of the guard’s forehead.Green and clammy skin flowed up toned arms to a face that writhed with suckered tentacles and bright glowing eyes. An armored mass of coral, or something akin to it, curled over the entity’s skull in a shape not unlike that of the human brain while two great curled black horns rose above and to the side of this curious armor.“Another sapling waiting to grow for harvest.” The voice reverberated through the room in a whispering hiss. A low growling groan escaped the human as he shredded out of his clothes. His eyes rolled, then flooded with the same green flecked with silver as his skin hardened into powerful hide. His jaw cracked into an inhuman maw full of teeth for ripping and tearing.“Waiting to mature like you and your brothers.”The brute rose to his feet as thick powerful hooves burst through his leather shoes. Long, sharp horns surged from his brow, cracked with molten red veins that pulsed like magma. The scent of sulfur and brimstone became more prominent as his hands blackened and swelled. Smoke hissed from them as powerful claws replaced flimsy nails. He surged in height and mass with sickening pops as bone and sinew reformatted.“No need for those pesky thoughts. You need only serve me.” He chortled as the gym’s logo pin that had burst off the uniform floated in the air, then pressed itself against the former guard’s chest. The new creature didn’t flinch when the hiss of roasting flesh filled the air. In a matter of moments, the deed was done, and the familiar mark of its master’s tentacle now bedecked the chest of this new thrall.The demon pulled his fingers away from the newborn thrall’s head, trailing the last streaks of silvery light with them. A mixture of moan and scream seemed to emanate through the room. And then both were silenced as the creature turned and knelt to its new master.“Such a good thrall.” The demon chuckled as he savored the last of the former human’s mind and soul. “You’ll make a fine addition to my army.” His eyes trailed over the screens and fell with curiosity on Kevin. “Perhaps we’ll see Lust blossom from that one. I suppose only time will tell.” Though there was no sign of a mouth to smile, one could almost feel the smugness the demon radiated. He cupped the new thrall’s chin. “As for you, little Wrath, well, I know many armies that will pay a high price for you and your brothers to serve them.” He chuckled. “Make sure it’s a massacre when I call on you. I still have a debt to pay to War, after all.”The newborn fruit of Wrath grinned, baring teeth that glittered like diamond. “Smash,” it growled in a guttural tone.“Through there.” The green claw motioned through a portal of flames circling beside the room. Great hulking brutes identical to the new thrall wrestled, fought, and otherwise vented their aggression in mindless violence.The creature grinned as it jumped through and roared its joy at the challenge.Arcane light surged over the coral structure as the demon turned back to the monitors and smiled as he gazed over his domain. “Ah, my little meatheads. How I love to watch you grow.” He chuckled as his eyes fell again on Kevin and the contract the mortal signed floated next to him. “Welcome to my little nursery, Kevin. I so look forward to the seeds you’ll plant here.” He chortled as his mark emblazoned itself over the fabric covering Kevin’s left pectoral. “And beyond my domain.” He licked the obscured rubbery flaps that counted for his lips. “What depravities can I water you with, I wonder?” He watched, and his tentacles twitched in anticipation as the man continued to grow. “I wonder….” -- source link
