(M tf Dog)

Alei is a very handsome young man and quite smart as well. With a smooth voice and a kind personality he had won over every woman he encountered without meaning to. Unfortunately his popularity made it hard for him to discern actual friends from 'fans'. It also kept him rather busy, trying to give all his friends their due attention while keeping up with his studies. This meant his little brother Anul was unfortunately left in the dust. When Anul was a little kid, he always played with his older brother. They were not just siblings- they were the best of friends too. Alei still tried to humor his little brother and talk whenever he had the time; when he had the time was now a rare occurrence. Alei is in college now while Anul is only in his 8th year of Low School.

Alei dressed himself in front of the full body mirror on the back of his door. His hair was only two inches long and black as night, he combed it back and to the side. He had a narrow beard on the end of his chin only that was also quite short, he let it grow in because without it he has a bit of a baby face. Alei's eyes were dark blue like the evening sky. He was not muscular but his body was tight and smooth- he was certainly fit. His wings are quite large and framed in black with metallic blue interior, and a few tiny emerald green dots. Alei is a Faerie, you see- living in the city of Anterra. Though it may look like a Victorian era human city- a single floor house was only as tall as the average human's chest. Relatively, Alei was a good height for a male, but on a human scale he was only seven inches tall. He wore a cable-knit dark brown turtleneck and grey jeans. It is autumn, and the surrounding forest around Anterra was filled with vibrant colored leaves, but the wind was also quite nippy.

Alei nodded to himself in the mirror but then felt an odd sensation as he stepped away, about to leave to meet up with some friends on his day off. It almost felt like passing through the surface of water. After a moment and nothing else odd happening, he shrugged and continued out the door. He walked down the hall and started down the stairs but slowed his walk. He could feel his penis press into the front of his underpants and then start sliding upward into an erection... for no reason. Had someone cast a spell on him? That should not be possible- the house was warded, as are all Fae homes. They are an inherently magical society and tricksters by nature, so naturally all Fae structures are constructed with anti-magic security in mind. He placed a hand over his crotch and felt his penis throb in his pants. His wings vibrated in nervousness. Alei heard one of the downstairs doors, but there was no reply when he called out. It was someone leaving, not entering. His little brother had the day off too and was probably heading out.

Well Alei did not want to go out with a tent in his pants, so with a frustrated sigh, he returned to his room to deal with it. Alei sat on the end of his bed and unzipped his pants to flop his junk out and work the pillar till it went dormant again. When he grabbed it though, it actually felt softer to his hands than he was expecting. What he did not realize is it had been erected by the formation of a baculum- a 'penis bone'. It actually was not more than half erect, it was being held out by the bone. When he squeezed the soft rubbery skin of the shaft though, it finished properly erecting itself fast enough. For a few moments it felt like it always does as he worked his shaft. It is about to his belly button, so the equivalent of eight inches if he were human sized; so its above average already. The shaft started to fell odd though, pressure but not equal all the way up, it was welling up toward the head. The shaft just under the glans swelled thicker, so the corona of the glans no longer projected out off the shaft, the shaft was wider than it is just slightly. This made his shaft look more like a baseball bat in shape. The urethra was oddly tight as well. In his hands the stiff tube felt like it did when something was firing out, except there was nothing inside at the moment. Then there was a bit of tension he felt at the slit at the very end each time he pulled his hand back.

Alei stopped a moment when his hand brushed his pubes and it felt freakishly soft! Where a sparse growth of pubic hair had been was now much shorter hairs, in a much, MUCH denser patch! There was a mat of very fine fur where pubes had been! Well now he KNOWS someone cast a spell on him! He has no idea why, but the only person who could have cast a spell on him is Anul! The house is warded against outside magic so it could not have been anyone else. Anul was inside of the building when it happened, so the warding would not have stopped it. But why would his own little brother cast a spell on his dick of all things? Worse still, Anul left just as the spell was starting to take effect and Alei doesn't even know where he was going. Alei grunt and resumed pistoning his shaft. He still could not go out with a raging erection.

The shaft felt like it was filling with more blood, swelling a bit larger, but the skin on the surface did not change along with it. The glans started to deform, the head becoming more blunted as the body of the shaft swelled forward and stretched it. The wider end of the shaft swallowed the corona, causing the glans definition against the shaft to vanish entirely, and theh head also lost its dome shape, making his dick more cylinder shaped than ever- it ends in a round blunt surface! The fur started to spread from his upper crotch, swallowing the base of the shaft and then fading in across his churning balls. His scrotum tightened a bit, making the curve of either ball more defined from one another. The tightness around his urethral opening continued as he worked his changing member, and while it was slow, he could now see it was growing longer. Just the urethra itself was getting longer, creating a bit of a spike-like protrusion from the otherwise flat head. The skin on his shaft became softer again, oddly. It pressed into his hand from within as it swelled a bit thicker and it took him a moment to figure out that it was just his foreskin. It was pulling back a tiny bit more with each stroke. The point where the foreskin and shaft linked together kept deepening! The exposed shaft grew tighter and started to look more red. The veins on the surface got smaller but more numerous. It was then Alei recognized its changing form- it was looking like a canine phallus! His foreskin was turning into a sheath!

He was sitting on the rather narrow foot board of his bed, which wasn't terribly comfortable to begin with, so only after realizing what his dick was changing into did he realized his discomfort was not entirely due to his seating! There was a lump growing down the back of his pants, and it was wedged between his butt cheeks from lack of room! He was growing a tail! He felt a pressure building at the base of his cock and re-positioned his hand at the base to feel around and sure enough, there was a hard lump on either side of the base of his shaft... a forming knot. He grabbed his shaft higher again, taking the end of the evolving foreskin so he could pull it further back. It disconnected from the shaft further and further down with each tug, till finally he could not longer feel a connection at all. The base started to clench a bit though. The skin there tensed, pulling his penis closer to his body. He was forced to place his hand higher up and then change the way he held it entirely because the sheath was fusing to his underside, preventing him from gripping around it. As it linked, the fur patch it interrupted wrapped around it, covering the entire sheath quickly.

Alei moaned and his entire body shivered a moment from the sensation as his dick suddenly surged in length! What had been his foreskin was now a sheath, and so his newly canine penis fully slid out from the end of that! So since his sheath went up almost to his naval his penis tip was now up to his ribs! The sheath swelled wider and wider, becoming very tight as the knot inside grew larger and larger. It was like half a ping-pong ball on either side, then half a golf ball, tennis ball, and then soft ball by the time it stopped growing. Well- relative to his body size. The nerves were pulled might tighter around the knot, so he gently squeezed his exposed red shaft with one hand, and the other held his soft furry sheath and swept it up and down over the knot. He was expecting to need to yank his pants down to allow his tail room by now, but for some reason it seemed to stop growing, and still fit in his pants, wedged in his butt crack. Alei bent forward, panting a bit as he felt the tightness further inside of himself. A familiar tightness now- the tension of impending orgasm. He looked across to the mirror on the back of his door, seeing a more full view of his large canine cock. He paused his masturbation a moment, teetering on the edge. Alei gently placed his index and thumb around the end of the sheath and with a thrust down from his hand, and up from his hip he yanked his massive knot free from the shaft. The scrunched up sheath pushed lightly on its back, his fingers pushed lightly on its front, and the knot throbbed so rapidly it felt like a vibrator as he climaxed! The end of his shaft swelled a little bit thicker, causing the blunted end above the urethral point to suck in a bit- making a soft divot at the end.

Alei gawked at his mutated dong as it softened. As soon as the knot started to shrink back, the sheath popped itself up and over it. He noticed a tightness in his fingers and looked down to see his nails were a bit more narrow, and quite a bit thicker than they should be! They were starting to grow out into claws- and the thicker they got the darker they became. His pants were feeling extremely tight. Alei stood up with a bit of effort, but when he went to stuff his genitals back into his pants they did not fit! His jeans were so tight he could not close them even minus the altered genitalia! His shirt was a bit tighter too, but it was much harder to notice because the material was much more flexible. He turned and put a palm on one of the posts at the foot of the bed and realized he was taller! In a flash of panic he realized why. If he were a human turning into a dog, he would be shrinking because even the largest dog is slightly smaller than a human. But he is a Faerie. Even the tiniest breed of dog is a lot bigger than he is!

Alei quickly grabbed at the edges of his pants but they were already so tight that he could not get his fingers in between his body and the fabric! He had to grab the belt loops to shimmy them off, tugging and and forth to work it down. As soon as his pants were half off his butt his tail popped out and shook itself. It was like a little sausage! As wide around as a silver dollar, it was as long as his middle finger and just ended in a rounded bottom. It is the nub-tail of a doberman pinscher! When he got his pants off he looked in the mirror again and groaned at the damage already done to his form. The fur that encapsulated his scrotum was black like his hair had been, but the sheath and fur flanking it was base brown. He felt a pinching sensation on all his toes and fingertips as his nails narrowed and continued to evolve into claws. He had to hurry! He rummaged through his things and found a pair of baggy sweat pants that still fit him even now. He usually only wore them around the house in the winter, but now he needed them as the only bottoms he could still fit in. He glanced in the mirror again as he opened his door to leave again, and noted his ears were changing shape. They were more triangular now and the cartilage was thinning.

Alei rushed downstairs and on his way to the front door stopped dead in his tracks and took a step back, looking at the grinning face of his rival; Valeh. She was sitting on the couch with her legs crossed, and a huge magic tome was resting on the table.

"My, have you grown Alei? I thought you were too old to be having growth spurts."

"You have a lot of nerve coming here! Undo this spell now and maybe I won't turn you into a flea in return."

She clicked her tongue. "But I am not here." As Valeh stood up, her form flickered.

Alei narrowed his eyes. "Astral projection... how are you casting spells through the walls?!"

She shrugged. "The tome your little brother brought inside. I did not cast the spell that afflicts you. Your brother did."

"Why?!"

"Jealous of all your popularity, so I seen his woes and offered him a spell he could use that would turn his older brother into a creature of legendary loyalty."

Alei grunted angrily and walked right through Valeh's projection to get to the tome on the table. "I will just reverse it myself."

"Go ahead. Just be careful you use the right reversal. You know; since you do not know exactly which transformation spell your little brother used. And I certainly won't tell."

"D-doberman, standard dog...?"

She shrugged again. "Sure, if that is what you think." Valeh then vanished from sight.

Alei growled, his teeth sharpening a bit. If Doberman was correct she would have put more effort into derailing his efforts. It either isn't a pure breed or there is more to the spell. If he uses the wrong reversal spell, he will return to being a Fae but the absent aspects of the spell it would try to reverse would screw up his body in other ways. If you mess up badly enough you could unintentionally delete a vital organ trying to undo something that is not there. Alei then hurried out the front door. He needed to find Anul, to figure out what spell he used in order to fix it before its too late.

It was a very gentle pressure at first deep inside, as his body slowly grew. Now that he was out and walking about, the growth was slightly less even, making the feeling more obvious. The pressure surged softly from within, travelling out to his extremities. His facial hair changed from black to brown, and started to grow out along his chin and upper lip- growing much faster than it should. It was also much, much softer than it should be. It is fur, not hair. He had to slip into a back alley when his toenails pressed into the insides of his shoes. Alei had no choice but to kick them off, groaning as he seen all five claws having ruptured the end of his socks inside already. The cool ground was already uncomfortable on his feet. His nails were all blunt-ended claws, solid black. As the growth spread through him now it seemed to leave a residual heat that helped him against the chill autumn air. His muscles felt stiff and warm, and every so often he would pause as he felt them squirm on their own. They clenched and swelled a bit, becoming larger and more defined. Doberman were very lean and athletic looking dogs, but he would not exactly consider them muscular. He had to be at least half of another breed of dog.

His ill fit clothing revealed his tight abs, and unfortunately also exposed the top of his sheath. He could not try to stuff it back into his pants because the sheath is already fully fused to his torso. If someone seen him in his state they would immediately freak out- his clothing did not come even close to hiding enough of his changes. Alei had to stick to back alleys only, dashing across streets quickly so no one spotted him. Because of the cooler weather most people were in chipmunk-lead wagons to stay warm while travelling which made it less likely Alei would get spotted. Black fur started to fade in on his shins and forearms, and then a brown patch on his upper chest. Now his body was a stark contrast to his surroundings- the air chill but his body quite hot. He had to let his tail out over his pants as they once again became too tight. The tail wagged on its own at first, but then he intentionally vibrated it back and forth. He could feel the muscle movement up the small of his back, and the still fresh muscle fibers felt good to flex. Alei walked past BFI bins that were only as high up as his hips now. There was a park nearby where people jogged and walked their dogs. Anul often sat on the benches in the shade there to read books. Alei was hoping he would be there now- otherwise he had no clue where to look.

Because of how the brown patch of chest fur wrapped over his pectoral muscles, it formed a perfect heart-shape. His nipples turned from pale brown to pitch black, and his lips turned to a glossy black as well at the same time. He grit his teeth as they grew more narrow but also more sharp, all turning to fangs. Alei groaned loudly- his voice now gravelly, making his groan more like a growl. He stumbled a bit forward as he felt changes swelling in his feet and hands. Alei slowed and then bent forward, breathing heavily as his entire body groaned deeply and quietly, while his clothing groaned in a louder, higher pitch. He grew in a surge so large that the crotch of his pants ripped a bit and his sweater deformed from stretching. He let out a sudden huff of air that almost sounded like a breathy bark as his rib cage snapped in rapid fire; it changed proportions, knocking into his lungs and forcing the air out momentarily. His rip cage became more narrow but did not actually change proportional size- it now projected further forward. Alei wobbled in place and put his hands on the wall of the building on the side of the alley to support himself. His socks slid down his legs as his feet stretched longer! The soles becoming narrow and longer. Four of his toes remained at the front, but when the soles started to lengthen his big toe did not move at all, causing it to become distanced from the others. Internally it shrank, and the bones fused together, becoming more simple as it regressed into a vestigial digit. His toes fattened up, causing them to press together and made them hard to move individually. The bottom of the end of each toe, and the entire strip of flesh along the conjoined base of all his toes swelled and the skin turned black! Alei was forced to stand on the padded fronts of his feet now as they finished devolving into paws! His hands went through the same process, though on his hands the first thing to form was the pads. Then his digits shortened and made themselves fatter. Then the palm of his hand stretched out, causing his thumbs to regress. The fur on his forearm and shins immediately started to spread again. Now wrapping fully around the limb and then advanced down to cover his newly formed paws!

He started to slowly plod forward, his balance on two legs was precarious now. He was standing on a much smaller percentage of his foot. The end of his nose started to feel colder as it became moist, causing the cool air to catch in it. It darkened to black, and a few longer hairs formed whiskers around his mouth and eyebrows. His eyebrow hair turned brown, though the hair on his head remained black. His facial hair was now fully grown in all the way up to his hair line- and all fully converted to fur. He yelped in pain a moment as another growth surge passed through him and his pants started to crush his balls! The pain was brief though as the tear in the crotch of his pants ripped even wider and his underwear bulged out through it, cupping his balls in the more flexible fabric. His shirt barely went low enough to cover his rib cage. It hugged much too tight around his shoulders and neck, partially strangling him. He made several more staggered steps forward, desperately trying to get to the park and find his brother. A sudden tug on his spine announced itself in several loud pops as both his back and his neck got slightly longer- this made standing upright even more difficult and gave him a far forward lean.

Alei felt a bit dizzy a moment, and zoned out, causing him to pause his advance even though he was so close to the park. It was just a few feet to the street that divided him from the park where he hoped his brother would be. Forcing his concentration back was about as pleasant as forcing yourself awake in the morning. He sniffed at the air, smelling something off. For some reason the smells around here were quite strong, so he was smelling a lot of things at once, but one especially interesting smell he could not put his paw on. His wings did rapid, micro-flaps and his little sausage tail started to wiggle rapidly without him even being aware. He felt a pressure in his crotch as his knot woke up and then his shaft started to slowly ascend, the red point of the very tip started to peek out. Oh no- his sense of smell must be good enough now to pick up on the scent of other Fae! Women often go to the park to jog, or do yoga routines together in the grass fields! Working out means they sweat, which puts their scent into the air and allows it to carry further! He was smelling females and it was causing his dick to wake up!

Alei tried to reach for his crotch but in doing so put himself too far forward and fell onto all fours! As soon as he hit the ground his pants exploded the rest of the way off him! He grit his teeth and growled as his entire body started to grow slowly now without stop! His underwear pulled tight and without hands he could not grab them to keep his nuts from getting crushed, so he hooked the edge of a claw on the elastic waste and cut it in half- the rip tore the rest of the way through as his genitals overgrew the underwear! The fabric of his sweater groaned more as he kept growing and finally tore just at the base of the collar, giving his throat some relief. His vision was starting to get blurry from how badly it was strangling him. He let out several short cries of surprise as more rips formed and his body jostled from the force of the tears- his cries sounding almost like short barks. Fur now covered all four limbs back to his torso. Most of his underside was covered in fur. His nipples were joined by six additional black dots, but they barely projected at all from his body so you would not see them at all through the fur- you'd have to rub his belly to even find them. He was so large now that his shoulders brushed the walls on either side of the alley! He could not turn around!

He tried to hustle forward but the fabric of his sweater was pushed into the walls on either side, catching. He was starting to grow even faster! The rapid growth made him hot, but his body could no longer sweat, forcing him to pant. The feeling of stretching larger and larger also helping his cock slide further out, and the knot to bulge larger in the sheath. Finally the sweater tore off completely against the walls, ripping in half as all the existing tears connected into one huge rift. He dashed forward several steps from the sudden release, but just as he was almost going to fall on his face, he got stuck again! Now he was so large his shoulders themselves were wedged! He was trapped! Alei was so close to the end of the lane that anyone walking by casually would be able to spot him easily. His panting became more rapid and desperate- the pressure of him growing against both walls was making it very hard to breath- his lungs could only half expand. This only caused him to draw more pheromones from the air through his lungs at once, causing his thoughts to become a swirling pool. His cock wobbled around from his attempts to squirm free, flicking long strands of salty precum this way and that.

Fur started to grow on his upper back. The walls on either side of him started to make sharp grinding sounds as the stone blocks started to shift against one another- he was starting to bend the walls in! Alei growled and grunted as his jaws started to stretch, making muffled clicking sounds as the bone shifted. The bridge of his nose started to equalize with his face as the face stretched further out, causing it to lose definition. His tongue grew quite large, but also became much more thin and wide too- it draped out over his bottom row of teeth like a carpet as he panted, and unintentionally let several drips of drool drop from its tip. Suddenly the mortar holding the stone blocks together shattered into gravel and the blocks shifted inward, causing holes to collapse into the walls of the buildings! The people inside either building rushed out onto the sidewalks to see what on earth was happening. Luckily by that time, Alei's face was already halfway to a full dog muzzle and he was no longer recognizable as himself. The iris of his eyes widened, causing the color of them to appear much darker than before. His ears now grew the muscle tissue in their base to allow them to pivot around- they automatically flicked in the direction of sounds. When idle, they stood forward and perfectly straight up in attention. His facial hair started to spread as his face finished growing out, consuming it in fur. The fur forming on his upper back connected the still naked parts of his torso and raced up his neck. More and more of the walls were shoved into the buildings, collapsing their sides as he grew larger and larger. Now he broke the blocks much easier, because they were so much smaller than him. The other Fae gathering, shouting in confusion at his front feet were tiny. They were barely taller than his forearms, and he was still growing at full speed!

Alei looked down at several of the Fae below him, seeing they were females and taking a deep breath of their scent. He groaned and shut his eyes for a moment as the fur on his neck and face connected. His longer Fae hair started to fall out and be replaced by ultra-fine dog fur. Because Alei was so much larger than the others, he had a perfect view straight down the cleavage of all the women. His cock jumped and tossed a gob of pre far enough to hit one of the women and knock her onto her butt! It was so big in comparison that it drenched her entire outfit in one hit! The others quickly started to back up now, realizing the danger. Alei momentarily forgot his situation and flexed his arms, pulling them back out to a position where they actually sat comfortably- but that mean decimating the buildings around him, causing half of the entire building to collapse in on itself! Still he grew larger, now taller than the buildings themselves. Alei tried to climb out over them but every time he put a paw down to pull himself forward it collapsed more of the building! He half-turned before he fell forward again from portions of the building collapsing out from under his paws. His upper paws smashed the lip of the roof off, causing his front limbs to catch on the roof and spread out, and his body to fall against the still standing half. The ruins falling around his cock made him involuntarily thrust forward.

More and more Fae gathered to figure out what was going on- along them was Anul. He ran over from the park and realized his error. He grew up in Anterra, so he had never seen humans or dogs in the real world before. When Valeh had shown him the images in the spell book of this 'creature of loyalty', the image comparison had been of a dog to a human, not to a Fae. Anul had no idea dogs were this big, he was expecting to return home and then be able to play with his older brother in this form, with undivided attention like it used to be. Never mind playing with him- he currently couldn't do anything but cause property damage. Anul ran home to get the spell book to undo it. Alei lost his conscious thoughts to the hormonal daze and gripped the edges of the roof on the building and started thrusting his gigantic dog cock through it. His dong was so massive compared to the building at this point that in a smaller room the sides of his penis brushed either wall! He seen and his eyes locked on a shocked-silent Fae woman standing in the window of her home a building over. Her window was across from the room Alei was currently fucking so she had a perfect POV of his cock rushing toward her and back again. The throbbing purple veins that formed a maze across its red surface. The Fae woman was wearing a form-fit top, so Alei's eyes were locked on her chest in his horny stupor. As his rock became diamond hard and started to vibrate more than buck, he gripped the roof even harder, his paws starting to crush the edges, collapsing the other half. He tried to shove even further forward, his sheath catching on some debris which managed to yank it back far enough to let his gigantic carriage-sized knot pop out and he immediately erupted again! The first wad of cum fired out hard enough to shatter the window, fly across the alley, and smash the woman's window! Before she had a chance to dodge, the second blast slammed into her chest and tossed the woman across her bedroom! By the time the jets of hot cum slowed to a lazy white drool, there was enough cum in the woman's room to form a shin-deep pool.

The other Fae were now so small compared to Alei that if his hearing had not become mush sharper, he would not have even been able to hear them yelling in confused anger. He tucked his ears back, he did not want to be a bad boy. Alei sat down to await any solid commands but doing so caused his rump to slam into a third building and smash the middle third of its back wall in on itself! He had transformed into the form of a Doberdane! Large, sleek and muscular looking- very masculine looking dogs. Large by normal dog standards- gigantic to a Fae. He could not move at all without smashing something under his paws, so he just sat there and waited patiently while licking his dick clean as it returned to its warm home. Anul had to command him to speak before he could use the reversal spell. The giga dog barking immediately caused all the gathered Fae to scatter like ants in fear. Anul then turned him back to normal before anyone returned. Everyone had only seen him mostly dog already, so no one knew who he was. Anul apologized a lot, but Alei knew it was Valeh's fault for tricking him, and a bit of his own fault for being too busy for his little brother in the first place. Alei promised he would do a better job of trying to make time to still play with Anul. And he promised to think of a nice punishment for Valeh once he got his hands on her.
