The cement practically crackled under Ethan's feet as he jogged home, his sneakers getting rather soft as they pounded the baked sidewalk. Sweat poured down the fourteen-year-old's chest but he didn't care anymore... Not about the heat wave, his shoes, anything. The blond boy had at last obtained the solution to all of his problems. Ethan turned off the sidewalk, crossing over the yellowed lawn before his house. He threw open the front door and turned, jogging up the steps to the top floor, moving into his room and shutting it behind him. The room was stale with old clothes left in a pile but Ethan didn't mind. It was his den, his space, his fortress of solitude. Ethan moved over and dropped his bag next to his office chair before he sank into the seat, his fair young face and blond hair reflected on the glass of the computer monitor. He took a deep breath and looked around at the walls covered with football posters, the stacks of VHS tapes... they were ancient, but they held old football games that he couldn't get enough of. Ever since he'd been a little kid his father had pushed football as the be-all and end-all of masculinity. Ethan agreed and it was their main way of bonding... but his first year of high school hadn't gone as well as he had hoped. He was too light, to skinny, too insubstantial to be accepted on the team. Ethan's heart had broken, but not into so many pieces as his father. It was on that day that Ethan started looking into alternatives... Ways to put on extra muscle, height, bulk. The conventional diets and exercises had done nothing. Ethan had to get creative. He talked to older boys, even people on the street... and finally he'd gotten the number of a scientist in Nevada, one that was an expert in hormones. Doctor Julian was the best in his field, and best... his morals could be overlooked if the price was right. The result was the container in Ethan's backpack, a package sent to a P.O. box... He lifted his backpack up and opened the zipper, withdrawing the brown box. He glanced out of the crack in the certain, confirming that the car was still gone. His parents wee picking up his little brother Nicky from elementary school. With one last double check out of the window, Ethan grabbed a knife and cut through the tape on the box. The seams popped and then he tore the box open. Inflated plastic bags protected the precious cargo, a metal oval container. The teenager withdrew the container and opened it up, gazing at the contents. Inside was a full length syringe, a dull amber fluid loaded into it... Ethan gazed at the container for some time, taking a deep breath. He lifted it out of the container, tossing the container to the side, cradling the syringe in his hand for a long moment before he cringed. The needle was so long... He knew he had to stick himself with it or the effect would be for nothing, but... he had to figure out a way to work up the courage. A squeaking and whirring outside warned that the family car had pulled into the driveway. Ethan cursed at his misfortune, moving to hastily tuck the syringe into his bookshelf between a layer of magazines and clean clothes. He stood up and moved out of his room, heading down the stairs to greet his parents and keep any suspicion from falling onto him. He had barely made it down the stairs when the front door opened. Nicky was the first one in, as he often was. While Ethan had been born with the blond hair of his father, Nicky looked a lot more like their mother with his dark brown hair. The eight year old ran in and toppled into Ethan, giving him a haphazard hug. "Did you have a good day brother?" Nicky asked. Ethan nodded. "Yeah, I did. Why?" Ethan asked, surprised Nicky had been interested. Nicky looked nervous. "Because you're going to need it." Nicky said, taking a step back before his father entered. "Ethan... I was hoping to see you down here. Saves me the trouble of yelling for you to come down." His father said, his voice gravely and hiding a bit of anger. Ethan froze. That was never a good tone. A moment later their mother appeared, a letter in her hand. "Ethan... We just got your report card. We need to have a very long talk."She said stenly. Ethan's head fell. It was Math... and English probably for that matter. He had spent so much time focusing on sports that his other studies had failed. "Mommy, daddy, can I go play video games?" Nicky asked. "That would be good Nicky, take your time." Their father said. Nicky gave Ethan one last glance for good luck's sake before he moved up the stairs toward his big brother's room. Ethan walked with his parents toward the dining room like a man heading to the gallows. Nicky truly did wish his brother luck, though he was just glad to be able to get out of the room in time. He pushed the door to his big brother's room open and moved in, glancing around before heading to the bookshelf. The young boy crouched down and began tugging on the drawer holding the video games. He gave it a yank but it didn't open. He gave it another yank and the whole shelf wobbled, the syringe slipping partway out of the clothes. Nicky tugged again and again before with a gratuitous yank, the drawer slid open. Nicky fell back onto his ass and saw something fall from the shelf. The needle jabbed into his leg, the inertia forcing half of the contents into his leg. Nicky gasped out in shock and pain, his eyes welling up... but he fought back his pain. He didn't want to cry, he would get in trouble and so would Ethan... and he was in enough trouble. Nicky pulled the needle out of his leg and whimpered, putting it in the drawer of games before shutting it. He looked down at the mark on his leg, where a drop of blood had leaked out. He reached down and ran his finger over it, but... without the drop of blood, he couldn't see the mark. In fact, it didn't even hurt anymore. Confused, the eight year old reached to poke and rub at his leg. There was a soft bump there, but it was getting smaller every few moments. Nicky grinned, thinking it could have been much worse. He was sure he imagined being injected; there wasn't any mark or pain. Still, Nicky wasn't wanting to get in trouble. He stood up and wobbled to the door, heading out of his brother's room. He hobbled across to his own room, heading in and shutting the door behind him... but something did feel different, something did feel strange. Nicky grunted gently, reaching out to grab the side of his bed. His balls soon throbbed, a sensation he had never had before. The tiny orbs tucked up so tight against his body started to descend. The stretched the flesh of his sack around them before blood began swelling his meaty member. Nicky had never had any feelings like the ones he was feeling at that moment. He grunted softly, his hips starting to thrust back and forth in the air. The thrusting got worse and worse as his pants tented... then the tip of his erection grazed the bed. Nicky's eyes rolled into the back of his head as he started humping his erection into the mattress. The pressure felt amazing, the motion felt like exactly what he needed to do, but something was still off. It didn't feel quite right... the cloth was getting in the way, or something. Despite wanting to surrender to his lusts, Nicky had enough mind to realize if his parents walked in he could still get in trouble. He glanced around before opening his closet door and climbing in, sitting down on the open carpet beneath his shirts. He slid the closet door most of the ways hut so only a crack of light got in. With a diminished chance of being caught, Nicky quickly unbuttoned his small pants and peeled them back, looking down at his Mario underwear... they were so tented and a little moist. Nicky didn't understand. It wasn't wet enough to have peed himself, but his cock had never been like that before... it felt so good, so very good. Nicky wondered if that was why his brother had the needle, to feel so good. Still, he wasn't going to waste the gift. He pushed his underwear down, his bare butt sinking into the carpet as he gazed down at his shaft. It was larger and thicker and harder than ever before, it had to be over four inches... and each time his heart beat it seemed to get just a little big bigger. Now the cloth was out of the way, but how was he supposed to apply pressure? It was almost like a puzzle. Nicky reached down to touch his cock and another electric surge shot through hi system. He shuddered, watching a clear dollop of fluid leak from his tip before running down the side. For some reason it made the eight year old drool in delight. He touched his shaft again, then again, then with more fingers. Soon, instinctually, the boy wrapped his fingers around his shaft and then moved his hand; first up to the tip, the down to the base, then up and down. Once more his hips started working, getting a hang of the momentum. The pre continued to drool from his cock, making it glide faster and better. Nicky humped his own hand, feeling the heat and pressure build. Every tie his hip sank to the floor, his cock slid down in his hand, it seemed to stretch is cock longer, as if he was holding it up and pulling it out like taffy... and every time he thrust his hips up, his cock held so tightly it was almost as if he wasn't allowing his shaft through and that the pressure squished his cock so it was wider... and he made a full cycle of thrusting every second. His ass cheeks were practically bouncing off of the carpet. In the diminished light, Nicky watched his cock grow to six inches, seven, eight... nine... He was three quarters of a foot long and it felt fantastic. He knew that the more shaft he had, the better it would feel, but something else was happening too. It was still getting harder as more blood flowed in. The boy's heart was working over time... But it wasn't just the blood filling vessels that were already there; new ones were forming...blood vessels close to the surface. His shaft was changing color, becoming redder... veins lined the skin, the mushroom shaped head of his cock quivered. Soon Nicky squeezed the shaft even more, but it struggled to get through, to squeeze through the small gap... His mushroom shaped head began tapering, changing, pushing into a point... It was looking less and less human before finally it had become something else, something far more canine. It was slick and hard and red and pointed, there was no other conception of what it could be... and Nicky didn't care in the slightest. He was fucking his hand like a mad man, his tongue hanging out of his mouth. His cock swelled more, ten inches, eleven... a whole foot of cock and he loved it. His shaft was almost a quarter as tall as he was, and he wouldn't have it any other way. As he realized that fact, the lust saturating his brain caused the base of his shaft to start contorting. At first it only grew puffy, but then on either side of his cock the skin started to swell and grow, almost like there were small balls embedded beneath the skin. He was forming his first knot. His brain told him that cum would be coming soon, but his balls seemed to indicate that was a long way off. Nicky didn't mind. He wanted this to last forever, to surrender himself to the bliss for all time. His aching foot long cock felt so good and he had a vice grip on it. Never before had his right arm had such a work out. His fingers were wrapped tight around the shaft, his palm grazing the length like a lover. Every muscle in his arm was tight... and oddly, starting to grow defined. While his cock had finished transforming, it seemed that his body was far from over. Something new was happening. Each thrust of his huge puppy pucker seemed to be changing his right arm. Almost like working a bike pump, each thrust seemed to inflate his arm. What had been a smooth, uniform, even arm was distorting as his biceps and triceps started to bulge, to stretch, to grow. The cuff of is shirt grew tight and almost painful, stretched to the max by muscle. His fair skin covered in peach fuzz started to change as the peach fuzz grew darker, taking on the brown hue of his hair. His palm swelled, his fingers grew longer. Before long it was as if someone had grafted the arm of a twenty year old onto the elementary school student and the arm knew its primary purpose in life was to jack off. Feeling lopsided, Nicky didn't want to leave any part of him out in the change. He brought his left hand over to his cock and carefully traded off, letting his left hand get a turn. In moments it started to inflate and swell as well, his palm growing as it brushed his tight knot, the hair thickening. It stretched longer from his shoulder, just as the right had. In moments he seemed almost ape like, his arms far too long for his body... but his right hand had lingered. While he jacked off with his left, his right finer circled his nipples, rubbing them one at a time, caressing the flesh beneath. His smooth young chest began to swell, a crease forming half way between his nipples, another running across his chest. His pectorals were swelling, his nipples getting thicker... and a soft dusting of brown fuzz was spreading across his chest. Not only that, a tingling came under his mature arms... It was pleasurable though as he felt soft, long hairs pushing under his arms, growing into thick manly tufts. Sensing that touch was the method of change, Nicky started moving his right hand around more. He ran it up and down his stomach, feeling the soft pudgy skin grow hard with muscle, the muscle pushing into a series of small segments... His abdominal muscles came in quickly, though they were soon obscure as thick brown hair began emerging all around the boy's huge cock before spreading up his belly, moving all the way to his belly button. The pleasure all over his body was so intense, so wild that he couldn't hold back. His legs flexed, his toes curled, his feet rotated in circles. There was so much goo feeling in his body that he couldn't hold it back and it was overflowing. The pleasure was tempered a little by pain though as his legs started to ache before the bones started growing longer. He would have been a mere four feet tall when he started if he was lucky, but now he was packing the inches on. The muscles in his legs grew thicker, his thighs swelling. His cute little baby feet were becoming less cute as the arch of his foot grew larger, his toes stretched, a thin dusting of hair spread across parts of his feet and then both of his legs darkened with a dusting of hair. Nicky had been changing one part at a time, bit by bit... but there was one part that had not changed. He had an eight year old head on the wide, strong, muscles body of a twenty year old with a huge dog cock... It had swelled a few inches past a foot once his body had grown, intent to maintain dominant. Sensing his inequality, Nicky reached up to start rubbing his face. His fingers found his jaw first, running over the edges of the bone that seemed to bend ad flex beneath his touch. He began working at it, giving himself a wider, more mature jaw. The baby fat melted from his cheeks, making him look more mature already... and shadows were spilling across his cheeks, the baby fuzz turning darker into an incredibly soft stubble. His fingers grazed his upper lift, the invisible fuzz there turning dark brown to give him a fine mustache. He practically groped his face as the fuzz moved to cover his chin and under his jaw. Soon his whole face was covered in brown fuzz, the start of a beard beyond his years, almost as if he had never shaved. Then again, he hadn't. His nose grew wider, his lips thicker, his ears larger. Nicky touched his hair and a blond streak moved through it, contrasting the dark brown covering his body... His mustache grew thicker, curling down over his lip, his beard getting bushier and thicker. It felt marvelous to drag his fingers through it, to feel every curl and contour, every bit. It was just as good as working his big dog member, but... that was the one thing, the riddle, the part that didn't make sense. Nicky opened his eyes, looking down at his big dog dick... it felt so good, the best part of him, but it wasn't human... it looked just like Rex's cock... and Rex seemed to like to lick it, to play with it, to rub it on things. Nicky started thinking about their dog and the knot at the base of his shaft only swelled larger, but it was only the beginning. The left hand working Nicky's cock started to change again. At first it was subtle. The brown hair across his arm started getting thicker, more hairs pushing out until his skin was disappearing beneath. Then his hair got softer, longer, becoming a soft of fur. His fingernails turned black and got hard, growing longer and pushing into points before they sank down into his fingers, disappearing for a long moment before the points pushed out of his finger tips and emerged several inches as claws. Portions of Nicky's palm swelled out as paw pads before the brown hair advanced, covering his hand and every part that weren't the swollen flesh pillows... he had the paw of a dog, but still he couldn't stop fapping. Once more Nicky felt uneven. He brought his human arm down and traded off, wrapping the fingers around his drooling animal cock, watching as they too developed claws, fur, paw pads... it was so animal, it felt so right. Nicky wanted to be an animal, he craved it. He fucked his hand far, bringing his puppy paw up to his face. His lips parted and he began to lick the pre from his claws and paw, but the juice had a dramatic effect on his face. His tongue grew wide and flat and incredibly long, his teeth grew sharp in his mouth. His lips turned black and his jaw began stretching. Nicky sucked on his fingers. He tried to pull his hand away but it wouldn't come out of his mouth, it was almost as if he was pulling his face out longer. His jaw stretched and popped, his beard grew thicker, his nose grew flat and followed the mouth. Nicky had stretched his face to nearly obscene proportions when the stretching jaw narrowed, coming to a point. The base of his nose turned up, becoming flat with where his lips were as the flesh grew black and moist. The soft hairs that made up his beard spread up past the beard line, covering his nose, circling his eyes, slipping up his forehead. The fur even surrounded his round ears. From the neck up, there wasn't an inch of visible skin. At last Nicky pulled his finger out of his mouth and smiled, panting, his tongue hanging out of his mouth. He reached up to rub at his ear, working it into a point, stretching it longer and taller. He reached around his head and worked on the other ear, making it pointed as well. As if sensing his intentions, once they were pointed, both ears started moving up his head, rising to the top... But Nicky knew he was far from done. As pointed canine ears emerged from his hair, Nicky had already started rubbing all over his chest. The thick hair that was there only got thicker; spreading out, brown fur obscuring his skin. His paws swelled larger, both against his chest ad around his cock. All the while his large manly feet were flexing, rotating, tapping... and the motion was just enough to trigger them. His toenails grew dark, grew long, curved and pointed before they sank down, becoming claws. The hair on his feet got thicker and covered more, surrounding his toes, the sole of his feet, his heel... and then the paw pads pushed out through all of it, the only hairless part of his feet. His legs were so long that his feet reached the other side of the closet, his claws digging into the wall as he flexed, but there was no stopping him now. The boy that had been eight years old and human looked far from it. He had the body of an adult, covered in hair with a huge cock, but more than that he was becoming canine. He had a dog head, a dog shaft, and dog paws... But while he knew there was more work to do, every dog needed a tail. Nick knew that well. Nicky stopped jerking off for a moment, a very hard thing to do, and lifted his hips up. His drooling dog cock bobbed in the air, heavy and commanding attention. While one hand kept him propped up, his other hand moved back. Nicky fondled his round plump cheeks with his hand until they were covered with fur, then he pushed his fingers between them. He hit the ring of muscle there, the flesh growing dark and firm before the hand slid up and found where his tailbone was. The nub started to grow, pushing out. Nicky felt it and then wrapped his fingers around it, squeezing and rubbing it like his own cock. It didn't feel as much pleasure, but the motions helped it grow quickly. With each thrust and tug he pulled his tail longer, brown fur starting to grow in over it. It was six inches, ten, twelve, fourteen... The tail kept growing longer, gaining muscle of it sown as the fur got thick enough. Soon it was whipping around under its own power, becoming thicker by the moment... And with the tail there, his ass cheeks were kept apart, his pucker now always visible to anyone looking at his ass. Nicky felt far more complete as a dog man, it felt as if for the first time in his life he was what he needed to be; so tall, so proud, so horny, so furry, so cute and handsome and adorable and dangerous. Both paws wrapped around his cock and it started growing larger in his hands. Nicky was confused as it reached fourteen inches, fifteen, then sixteen. For some reason he thought it had grown compared to how tall he was, or was supposed to be. If it was longer, maybe he was supposed to be taller. As Nicky imagined that, he grunted hard. His spine aches, his legs throbbed... and he started stretching more. Even his arms lengthened as his body contorted. A moan escaped his canine muzzle as he reached five and a half feet tall, six feet... six foot four, six foot six. His legs were bending, trying to make room for him in the closet. His back slid up the wall, his ears pushing into the fabric hanging above him. He panted and whimpered happily. The closet grew impossibly tight as Nicky grew to six foot eight, six foot eleven... then passed seven feet. There was a creaking before the closet door gave way and fell out onto his bed. The huge furry canine rolled out and spread out, his incredibly long furry legs stretching, his arms bulging. He panted happily, his long tongue hanging out of his muzzle as he grew to seven foot two, seven foot six, seven foot eight. He was taller than any door in the house, more than any basketball player... for it was basketball that was Nicky's favorite sport. While Ethan had loved football, he loved basketball... and thanks to Ethan, Nicky was tall enough to win any game and then fuck all the other players, yes, that was what he was meant to do. Nicky started imagining all the good things he could do with his canine meat, forcing it into mouths and asses. He had never thought about sex before, but it felt so right, so good, so perfect. That's what he had to do... He had to feed his cum to his friends, to Ethan... to show them how wonderful life could be, and to be the strong alpha male he was. Nicky growled happily, glad to be the man in charge. He imagined asserting his dominance and it was just too much. His aching, engorged cock pulsed and throbbed, shuddered... and then unleashed its load. A thick rush of cum launched out of his pointed cock. Nicky spread his lips wide and let it splash across his tongue and teeth. He gulped his sperm down greedily, swallowing happily in wonder and bliss... but there was too much. It leaked out, soaking his brown fur, dripping across his chest. Nicky continued to cum, the sperm far more than he could handle. It showered over his chest and arms, soaking his fur. He was a wet dog, wet with sperm.... But Nicky loved that, showering in his own musk. He gave up trying to drink it and he moved his cock, wriggling it around, coating himself from head to toe. Even his tail was soaked and dripping, the milky white goo covering every inch of him. He panted in bliss before his orgasm ended and his knot started deflating. The huge wolf went limp against the bed and he grunted, panting, trying to reclaim his strength... because he had to show his brother what a man he had become... the personal best that he had achieved.
