(F tf Dog)

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

Alei dressed herself in front of the full body mirror on the back of her door. Her hair was to the small of her back and the color of honey. Her eyes are a forest green, and while she was not at all muscular, her body was tight and quite fit. Alei's breasts were a bit more than a handful each and pert teardrop shaped, with red-pink nipples. Her wings are quite large and framed in black with metallic cyan interior, and a few dots of pink. 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 humans' chest. Relatively, Alei was a good height for a female, but on a human scale she was only six inches tall. She wore a cable-knit sweater that was far over-sized for her. The collar hung off one of her shoulders exposing it bare, and the sleeves were so long her hand up to her fingertips was hidden. The bottom of the shirt covered her crotch and the upper part of her thighs. She had a loose black skirt on under that down to her knees, and thigh-high grey socks under that to keep her legs warm. It is autumn so while the forest around Anterra was alive with colors, the wind was also quite nippy.

Alei nodded to herself in the mirror but then felt an odd sensation as she stepped away, about to leave to meet up with some friends on her day off. It almost felt like passing through the Surface of water. After a moment and nothing else odd happening, she shrugged and continued out the door. She walked down the hall and started down the stairs but slowed her walk. She could feel a heat building in her crotch, and her vagina started to gently clench on its own. It was like she were suddenly quite aroused... for no reason. Had someone cast a spell on her? 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. She placed a hand over her crotch and felt her labia throb! Well... that isn't normal. Her wings twitched in nervousness. Alei heard one of the downstairs door, but there was no reply when she called out. It was someone leaving, not entering. Well, that must have been her little sister heading out- she had the day off too.

Alei was definitely not heading out with her vulva suddenly on turbo, so with a frustrated sigh she returned to her room to deal with it. Alei sat on the end of her bed and then plopped onto her back, sliding a hand down her skirt and then using her wrist to shove the waist of it down along with her panties. It was very sensitive, and she gasped softly at how good it felt to touch. It was like she had gone years without a lover. She wanted to be more worried and quizzical of the suddenness of it, but her pussy was too hungry and demanding at the moment. Her clit throbbed as she rubbed her labia and then slowly sunk her fingers in more with each pass. Her pinky and index remained resting on her labia, the ring and middle finger explored the depths. She was going to grab a tit under her shirt with her other hand but instead kicked herself further up the bed with her feet to grab the drawer on the nightstand and go for her vibrator wand. Boy did this thing kill batteries, but it also did its job real good. She turned it on and pressed it over her clitoral hood and then quickly turned over and shoved her face into the sheets to muffle herself after she let out a high pitched squeal that could break glassware. Her body was flat on the bed except her ass raised in the air, half exposed over her skirt. One hand diving into her increasingly wet hole while the other held the buzzing wand to her crotch.

Her clit pressed into its hood and then popped out! It never did that on its own before, hers was rather small. Or, it was small- its not now. Her wings vibrated almost the same as the wand- micro movements at a very rapid pace. It was unintentionally raising her body temperature. She did not notice since they were busy in her crotch- but the nails on her fingers and toes all started to get a tiny bit more narrow and a LOT thicker. The thicker and blockier they got the darker they looked as the material became dense. Her nails went from clear to milky, grey, charcoal grey, and finally matte black entirely as they extended out, but did not get any sharper. The muscles in her crotch were already twitching wildly so she neglected the feeling of new muscle forming in the small of her back as her tail bone started to extend. With her forehead still pressed heavily into the bed, Alei looked down to see her clit swelling even larger! It felt almost itchy with how tight it was being pulled by internal pressure. If she took the vibrator away from it for even a second the itch drove her nuts. It looked like a fat Lima bean!

Her ears felt hot and Alei's cheeks flushed bright red. The cartilage in her ears started to thin, but to make up for it their surface area started to grow, causing the ends to droop a bit because they were getting bigger than their own structure could support. Alei started to worry a bit when she seen pink dots appearing on her underside, looking like irritated skin at first, but far too uniform. They were like bug bites, but why all of a sudden? Her clitoral hood and labia started to engorge from arousal too, especially around her clit, causing it to billow outward. Which isn't something it would ever do normally. Her tail bone had extended even further by now, and the muscles growing in its base caused it to flick erratically. It was at least six inches long and still growing out slowly. Alei flopped over again onto her back, taking the soaked vibrator away for a moment to give herself time to breath- she is panting heavily. She rubbed the bumps on her stomach and they felt oddly sensitive, almost slightly pleasurable. They also started to stand up and the skin scrunched up and stiffened! They were nipples! Eight nipples, starting from just below her rib cage! She grabbed them one by one and rolled them between index and thumb till they were standing up stiff, and once they were all standing in attention she started to rub her palm up and down them. Her clit still throbbed below and itched for attention but her pussy was feeling oversensitive. She did not want to keep assaulting it with the vibrator at risk of rubbing herself raw with it. She reached back into the drawer and grabbed her dildo- it was a good size one too, but she had just been using the vibrator for a long while now so she has not seen the dildo for some time.

She plunged the dildo in and was immediately surprised at how... little it did. It felt much smaller than she remembered it being. Her pussy had become spoiled by the vibrator and now it felt like the dildo could not do its job at all. She sat up shakily at the edge of the bed and was going to use the bed to hold it in place so she could work her crotch and nipples with her hands, but to her surprise the dildo popped entirely inside of her! It was so deep in her that her labia actually fully closed behind it, swallowing the toy like a snack! That wasn't normal! Her pussy isn't that big! Alei looked around and seen how tall the bed posts were compared to her and realized her entire body had grown! That is why the dildo did nothing for her, her entire vulva was bigger! Then her lust addled mind caused her to fixate on the large knob on the end of the bed post as she bit her lip in thought a moment. Her pussy kept clenching on its own so she actually had to reach into herself to try and fish out the devoured dildo to toss it aside. She put one foot on the bed and one on the floor and stood on her toes a second before pushing her pussy down on the bedpost knob and popped the entire thing inside of her! She cooed in pleasure and her legs trembled, causing her to slip a bit and the post rammed its way up into her way further than she would have thought.

Alei started thrusting her hips back and forth, hooking the large knob inside of herself and rolling it back and forth. She still did not notice her tail- now almost down long enough to reach her knees it was covered in a dense fluff that was quickly growing in length and weight! The hairs were rapidly getting longer, trying to match the hair on her head exactly. Her labia got still fatter, turning a very dark pink, nearly red. Her pelvic floor suddenly shifted a bit, and Alei squeaked like a distressed mouse as her pussy was pulled further back, causing the bottom to squish out horizontally slightly. This also yanked the skin on her stomach and crotch tight for a moment before it was able to grow lax again, and it helped space out her clustered nipples better. The nipples on her breasts started to regress, and the coloration of the areola started to fade to a normal skin tone! The fur on her tail was so long it easily doubled the length of the tail, making it very bushy and as long as her legs are!

Alei gasped and paused her aggressive thrusts and the squelching sounds of her wet pussy on the bed post when she heard the sound of splintering wood! She realized she was even bigger! Alei tried to pull off but stumbled. Rather than impale herself on the bed post, her pussy ripped it completely off! She fell back with the post still in her- she tore the corner of the bed off with just her vagina! The post fell out of her quickly- it wasn't even a good fit anymore. She looked around her room in a daze and realized she was as tall as the doorway itself! She is a giant! Well- a giant by Fae standards, she is still small enough for a human to pick up in one hand. When she turned her head to look around the noticed her changed ears- because now they were completely folded over themselves from their length! She closed her bedroom door to see the mirror on the back and gasped at her appearance! Her ears were large and floppy, and the fur had grown massively on their backs as well, making them blend in almost perfectly with her human hair! She then seen her tail and blunt black claws where nails should be.

Well, this is a problem. She KNOWS someone cast a spell at her at this point. But if the building itself prevents spells from entering... that only leaves Anul to have cast the spell. She was inside of the house when the spell was cast, so the wards would not have stopped her. But why on Earth would Alei's own little sister do this to her? Where would she even learn about spells that can do this? She isn't even in High School yet! The itch in her angry clit was still there, but more subdued now. Her pussy was tender and she was tired from working herself over. Alei needed to find Anul to make her fix this! Unfortunately, that was Anul she heard leaving the house earlier- and Alei doesn't know exactly where she went.

Alei put her clothes back in place the best she could. She had to hike the waist of her skirt higher than she would normally wear it so her tail did not get pinched behind her and could swish around under the fabric. Her panties below that were a bit further down, so the tail could go over those. Her swollen labia pressed into her panties uncomfortably but there was nothing she could do about that. Her nipples were almost invisible now, and her breasts were smaller, so she unclasped her bra and just tossed it off before heading out. Alei dashed downstairs and was about to go out the front door when she stopped and took a step back to look at the grinning face of her rival; Valeh. He sat with his legs crossed in the living room, a huge closed tome resting on the table in front of him.

"My, my, I never knew you were so tall Alei."

"Rather bold of you to be in here, you wretch. How the heck did you cast magic through the building?!"

He shrugged as he stood up, and for a brief moment his form flickered. "I didn't."

".... Astral projection."

"Using the tome your sister brought into the house as an anchor, yes. As for the spell itself, well, your sister did that. It seems your dear little sister was feeling abandoned by you. I told her I had a spell that would turn you into a beast of legendary loyalty, so that you would pay attention only to her."

Alei realized the problem with that as her heart jumped. A creature of absolute loyalty... she is being turned into a dog. That is why her libido is going berserk- she is going into heat. The bigger problem however is size. If she were a human, she would be shrinking because even the largest breed of dog is still slightly smaller than a human. But even the tiniest breed of dog is still a LOT bigger than a Faerie.

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 right ahead. Just be careful you use the right reversal. You know; since you do not know exactly which transformation spell your little sister used. And I certainly won't tell." Valeh leaned toward her and whispered 'good luck' before her projection vanished.

Dammit, she doesn't know what breed of dog she is turning into. Using a reversal spell on something you are not can cause parts of your normal body to also get undone, potentially removing vital organs. The only way for Alei to undo this is to track down her little sister. There is a nearby park that is pretty popular stop for everyone in the area- Anul often sits on a shaded bench there to read. If she is not there, then Alei has no idea- another disadvantage of not talking with her little sister as much anymore.

Alei put on a button up scarf and dashed out the front door, but decided to scoot into a back alley rather than take the sidewalks to the park. Someone might see the tail waving around under her skirt. They might see her ears too, but that was less likely as they really did blend in perfectly with her hair. Everything looked just a bit off to her, because Alei's body was still growing so everything was smaller to her than she was accustomed to. She only made it through two alleyways, dashing across the street in between quickly so no one seen her, but then slowed and had to hold the wall for stability. Alei cried out as her voice became gravelly and her cry of surprise sounded more like a dog growl. Her spine and neck popped several times on their own and both became slightly longer. This caused her to have a forward lean when moving. Her skirt was starting to dig into her hips and her giant sweater started to fit her like a normal sweater. When Alei felt the sweater pulling out straight on her chest she immediately looked down and seen her breasts were entirely gone! Nipple and everything- her chest was blank. The fat nubs down her stomach were her only tits now.

Alei walked further, now her steps heavier and more deliberate. She watched the stone blocks that made up the walls on either side of her, the line between stones sinking lower as she continued to grow. She stopped suddenly at the loud snap as the waist of her skirt finally gave up the ghost and fell away! She blushed at the bulge in her panties as Alei now seen how sopping wet they were. She pulled them away from herself and her eyes widened at the state of her engorged pussy. Her clit remained the size of a Lima bean in regard to the rest of her body, but the clitoral hood swelled to become a more direct extension of the labia- projecting far enough to swallow the clit once again and hide it from the outside world. The labia had swelled up so soft and fat that they turned from dark pink to a bruised pink-purple! Since she was forced into a state of being in heat, her labia would probably still grow even further out from her. She could not wear her panties over that huge puffy triangle without driving herself nuts.

She slid her panties off and just kicked them to the side, but then wobbled and bopped her head on the wall in front of her! Alei suddenly lost balance, her shoes were tightening to her feet! Her toes and fingertips were tingling from increased blood pressure and she looked at her hands to see the skin there billowing out too! The tips of all her digits as well as the unified base of them all was swelling into plush bubbles of dense flesh- paw pads, to protect them against the hard ground. Alei did not want to have to take her shoes off too- but she supposed it was pretty trivial in comparison to her exposed privates, and she did not want to risk having her feet crushed if she doesn't remove them quick enough. She had to pull quite a bit to yank the shoes off and groaned at the sight of her blunt black claws all sticking out of the front of her socks.

Alei walked awkwardly now, not only because the pads caused her feet to not sit right against the ground but because the bones inside were building a pressure. They were trying to change even more, but she had to get to the park as quickly as possible! She placed a hand on a BFI and gasped as she realized what it actually is! She thought she was putting her hand on a trash can or something to balance herself- the entire BFI was only up to her hips! She supposed it was a testament to how oversized her sweater had been, because it still fit. Her entire body felt like an inferno now- the growth made heat but her body was no longer capable of sweating to get rid of any of the heat! She was breathing deeply, letting some of the heat escape with the moisture of her mouth. Her jiggly soft labia progressed from bruise purple to glossy black now, and her lips also darkened and turned black to match. She let out a very canine whine as she fell to the side, leaning against the wall. Her clit kept throbbing inside her, her swollen pussy itchy and penetration was the only cure. It was impossible to concentrate!

Valeh dashed past the alley ahead then doubled back as he realized she was there. Valeh was afraid she would find her sister before the spell took full hold, so he decided to track her down to try and slow her in person. He smiled and casually walked up to her, she was too dazed and hot to move or react.

"Well, having troubles there Alei? That transformation looks like a real bitch."

"Hnnn nee-need f-fuhuuuck." She looked at him blushing bright red. "Make it stoooop."

"My! That is an unexpected offer, but sure. I did this to fuck you over after all- this is just more literal than I expected."

She had grown so large there actually was not enough room for him to get around her, so he crouched and went under her instead. This would slow her down plenty long enough. He did not even bother unzipping as he looked at her giant plush cookie. It would be like throwing a pin down a hallway- her entire body was so large now that her triangular vulva was now as big as his entire torso! He was about to reach up and guide it down so he could do anything with it, but just then she slide along the wall and fell to all fours as the bones in her limbs made some muffled pops. Her arms and legs were getting a bit longer, and her soles and palms got a LOT longer! The holes on her socks tore further up now and finally they burst all the way off from her- even their elasticity has its limits. The thumbs on her hands and the big toe on her feet regressed, the joints fusing as the bones simplified and the digit was left behind as the others grew out- becoming dew claws. Her fingers squished shorter, and both fingers and toes swelled up fatter. They pushed against each other from lack of room now, making it difficult for them to move individually. She was on four paws now. As if to accentuate that fact, a fine pale sandy fur formed around her claws and slowly started to advance around the rest of her paws.

Alei's tail was curled between her legs as she whimpered at her devolving hands and being forced onto all fours, but as soon as Valeh touched her pussy her tail shot up and started wagging involuntarily again. The long fur on the tail trailed behind it because of its length, it almost looked like a waving flag. Each plump labia felt like soft, hot rubber and was so meaty the labia alone could fill either of Valeh's hands. The pussy projected off from the body as an invitation when dogs are in heat- and stretch to follow the cock on the back thrust, refusing to let go. While the outer flesh was black, as Valeh stuck his entire arms into the opening and pulled them a bit apart, he seen the insides still faded back to pink. In the bottom corner of the triangle her bean-shaped clit still flexed. Because of her size the clit was larger than a football to Valeh. The moment he touched it with one arm, the pussy clenched and forced his other arm to let it pull shut again on his arm! Moisture pooled on the inside but could not escape the grip of the fat labia. He rubbed the smooth clit back and forth and her entire rear end moved up and down slightly following its motion. Alei's tongue started to hang out as it grew longer and became wide and flat as well- lolling out of her mouth over her bottom teeth like a carpet.

The fur at the base of her tail started to slowly climb her back as a narrow stripe, but as it advanced up the base started to spread as well. Fur covered all four of her paws and started to fade in up her long limbs as well. Muffled snaps and cracks sounded from her face and she whimpered as her jaws started to stretch out and drag the rest of the face with it slowly, and then she abruptly barked. She grunt with frustration in her squatting position as her shoulders and thighs started to brush both walls at the same time! She was too lost in her lust to realize just how bad that was! She was incapable of turning around, and would be completely trapped if she did not move soon! Alei made several strange yips and grumbles that were almost words but not quite, and her teeth all grew sharper in her mouth as it continued to get longer! The bridge of her nose became wider, equalizing with her stretching face to lose definition and becoming just another part of her muzzle. She overgrew the alley entirely as the walls started to push in on her, and even Valeh was startled as she let out a loud bark abruptly, echoed with the sound of several cracking bone joints! Her rib cage suddenly became more narrow but projected further forward- momentarily knocking the air out of her lungs as an involuntary bark! This also narrowed her form slightly allowing her to move again.

Fur started from her tail was now also spreading on her upper back by now, and her pubic hair had turned fur in her crotch and was spreading from the bottom. Long honey colored strands of hair started to fall from her head to the ground as pale sandy fur started to grow in its place! The fur on her elbows and her thighs grew a bit longer than anywhere else on her body, becoming wispy but still not nearly as long as the fur on her ears or tail. Alei stood up straight as her upper body was released from the grip of the wall but then her heart jumped as she felt Valeh start to slip from her pussy! Standing upright pulled it far too far off the ground for Valeh to reach so he was about to slide out- unable to grip properly on the wet soft skin. Alei backed up quickly, intending to pin Valeh against the wall behind her to hold him to her pussy but unintentionally slammed him against it hard enough to wind him! Her wet pussy squished out against his entire body, punning him in place!

Alei's body started to grow even quicker now that her form was mostly lost. The black frame of her butterfly wings turned to dark brown to transition a bit better to her fur, fading to gold where the two met. Valeh could feel very easily how much she was growing, because the soft labia of her wet searing hot pussy spread even further around him, allowing him to move slightly in the Y shaped cleft. Her increasing size caused her butt to grind harder against the wall behind her though, and the entire structure started to shake a bit from the force of the giant dog grinding on it! Her thighs had a bit of breathing room in the T shaped crossing of alleys but her front legs got stuck quickly again by the walls on either side and ruptured the walls entirely suddenly! She was starting to demolish the buildings around her! She did not get to her sister in time- the heat was too much to stand. Even now her pussy burned and itched with need- she had a similar problem to when she used a dildo earlier; the toy she tried to use was now too tiny to do any work. Except this time the toy is Valeh. Alei's face still pushed even further forward, becoming even longer and narrow! The end of her nose turned a textured black and became cold and wet. A few hard to see whiskers sprouted around her mouth and two from either eyebrow- though the eyebrows no longer had any definition on her face against the rest of the fur consuming it from where her hair used to be. Her ears still made it look like she sort of had human hair though- and were a deeper tone than the rest of the fur, being closer to the honey her hair was. Alei has become a Saluki! A lean, tall breed with a long narrow face. Because of its slender figure and hair-looking ears, they have a very feminine aura.

More and more Fae gathered onto the sidewalk at the end of the lane Alei faced down, shouting in anger and confusion. They startled her and caused her to try to back up- forgetting her crotch was already grinding against the wall behind her. Valeh had to take a deep breath as he was jammed completely inside of her pussy! Her giant dog rump smashed through the wall, then the top floor of the building collapsing an entire quarter of the structure with her ass alone! Even more Fae pored out from the surrounding buildings to try and see what the hell was going on. Among the gathering Fae was Anul! She heard the destruction her sister was causing from the park which was not at all that far away, and dashed over to see her. Only now did she realize the error she made in trusting Valeh. She grew up in Anterra, so she had never seen humans or dogs in the real world before. When Valeh had shown her 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 her older sister in this form with undivided attention like it used to be. Never mind playing with her- she currently couldn't even do anything but cause property damage. Anul ran home to get the spell book to undo it. Alei lost her conscious thoughts to the hormonal daze and lifted her tushy back out of the ruin. Valeh popped his head out briefly to get a breath, but then was forced back in when she slammed her pussy back into a still standing section.

Alei ground her pussy against the more solid chimney of the building but still snapped it in half all too easily. Once her butt smashed the building around it away though... it provided a vaguely phallic shape. She squished her pussy down on top of it, wiggling so the edges of the chimney were pressed on the inner curve of her pillowy labia and then thrust down! Valeh was hit by the chimney inside of her and forced even deeper into her body! The Fae who had been watching groaned and averted their eyes from the gigantic canine impaling herself on part of a building. Alei thrust up and down on the chimney which was just wide and long enough to scratch her itch. The clenching muscles of her pussy gripping the brick caused them to grind together and groan- threatening to collapse from the force. As she approached orgasm finally, Alei's legs shook and the strength started to drain from the electric pleasure firing through them! As she climaxed she slammed her rump down all the way to the ground, forcing the entire remaining chimney into her hungry hole! Valeh was shoved even deeper, getting slammed up against a giant dog cervix! After a short bit, Alei stood back up onto all fours, snapping the chimney off inside of her, but then relaxing her pussy finally and the loose bricks tumbled out of her along with a ton of natural lube. Finally, Valeh fell out gasping for breath and coughing up gobs of salty dog lube. Being crushed against her cervix by a chimney almost drown him in pussy! That ought to teach him to fuck with Alei!

With the itch finally gone, the heat slowly started to cool, so her panting slowed. Alei plopped back down on her rump and lifted one leg so she could bend over and lick her pussy clean. Valeh slowly dragged himself away, none too pleased. His hair and clothing was so sodden with her juices that his body felt twice as heavy as it was. The other Fae were now so small compared to Alei that if her hearing had not become much sharper, she would not have even been able to hear them yelling in confused anger. She tucked her ears back; she did not want to be a bad girl. Alei sat and waited for any solid commands, but doing so crushed the corner off yet another building. She could not move at all without smashing something under her paws, so she just waited patiently for Anul to return. When Anul arrived, she had to command her older sister to speak before she could use the reversal spell. The giga dog barking immediately caused all the gathered Fae to scatter like ants in fear. Anul then turned her back to normal before anyone returned. Everyone had only seen her mostly dog already, so no one knew who she was to pin the property damage on her. Anul apologized a lot, but Alei knew it was Valeh's fault for tricking her, and a bit of her own fault for being too busy for her little sister in the first place. Alei promised she would do a better job of trying to make time to still play with Anul. Valeh had already learned his own lesson, nearly drowning in his own handiwork, so they doubted he would show his face anytime soon.
