The kitsune Keiko seeks out training to better learn her yokai powers and finds her way to the rugged kamaitachi Fuku The Flurry for a lesson on shapeshifting mastery.


1545, Nippon

Fuku puts his tiny pink paw pads to his aching head, and pets a strip of angry red flesh down the side of his face. A scar- but so fresh that is has barely closed. His eyeball itself was cleaved in half too- he removed that entirely to avoid complications, since the eye itself obviously won't work anymore even after it has healed. Fuku is a weasel you see, and one that just came out of yet another life-of-death bout. Those were pretty common for him, but it is less common for his opposition to be able to land a heavy blow like this one.

He paces around the newly polished floor of a large temple carved by the winds out of the top of a mountain by a dai tengu- its former owner before Fuku hijacked the place. When a weasel becomes strong enough, they can ascend and become a yokai known as the kamaitachi- literally translating to 'sickle weasel'. Among their powers; the ability to move faster than the mind is even capable of thinking, and thus far faster than the perception of any living being's ability to keep up. Including their own. THEY also cannot think as fast as they can move, requiring them to move entirely based on muscle memory and instinct in order to act at those speeds. Moving that quickly however- they can move forward faster than gravity can pull them down, allowing them to quite literally walk on thin air. So what do they busy their conscious mind on, if their combat technique is left entirely to the unconscious mind? Well, a lesser known fact is that itachi are master shapeshifters. Though hundreds of other yokai also know how to shapeshift; itachi can memorize the highest number of forms.

Fuku narrowed his eyes a moment, and for a split second the red-brown fur of his back bristled. There is another yokai approaching fast, and he does not recognize its aura.

The red fox Keiko approaches his shrine; at first as a discolored robin to fly to the lofty perch before turning into a three tailed fox again and plopping down just outside. The temple has no walls- the roof is held up by stone pillars and the entire temple was etched from one large, uninterrupted stone. Keiko has been travelling around trying to do her former master proud by thwarting evil wherever she can find it, but that has started to get difficult because of her inexperience in shapeshifting. She still wears the colors of a red fox when transformed as a robin making her stand out. If she is bumped or otherwise loses concentration while turned into something her fox features start to pop out! And she has only been able to take a handful of forms even at that- mouse, robin, horse, human, and once a snake briefly but the form was too difficult to hold.

Keiko walked silently into the huge room looking for the itachi she knew was here but unable to see. Fuku appeared in a human form wrapped in a cloak, already over Keiko! She jumped to the side to avoid him stomping down on her. Fuku smiled and Keiko was then smashed against the floor hard by a blast of wind, forcing her legs out to her side to pin her furry white belly to the floor. Fuku did not need to actually touch her- the force of him having moved that fast caused a tremendous vacuum of air pressure which hit Keiko for him just as a side effect of him moving.

What had been a gnawed toothpick transformed back to its true form- a dark wood staff for Fuku to lean on and to poked Keiko with the butt of it before she could get up.

"Ooops, don't tell me I broke you already? Collapsed lung?"

"I-I come in peace!"

"Well, you'll leave in pieces if you don't start talking. I get bored easily."

Keiko told Fuku that she had come here seeking training in the art of shapeshifting! She had heard of people talking about a kamaitachi named Tozoku causing trouble, so she listened in and heard about them being expert shapeshifters too. Her attempt to track down Tozoku failed however, and what tiny bits of information she tracked eventually lead her down this way. In the spirit realm side of things however- Fuku had made a beacon of this place, bragging about having usurped the temple from a dai tengu, using the flaunting as a sort of challenge against any would-be contenders. In reality Fuku's former posse had died taking this place, and kamaitachi always travel in threes... so without two more itachi; Fuku wasn't going anywhere. He was trying to attract other weasels to recruit a new group, but ended up calling Keiko here instead.

Fuku sighed, turning his back to her and wandering toward the back of the temple where a stone seat waits for him, his staff clacking against the stone floor. "You won't find Tozoku, because I killed him."

"Then that means you are the more skilled of the two. I heard he was a troublemaker for the humans, so you probably also saved a lot of people the trouble of dealing with him."

"Unintentional." He turned and plopped down on the seat, the many layers of his faded clothes billowing a moment from the movement. "You see; I am not generally the helpful type. I don't want anything, so you have nothing to offer me in exchange. Having a fox around might scare off potential challengers so... shoo, fly. Don't bother me."

Keiko plopped her butt down firmly on the floor, tucking her bushy tail around her side. "I will not make a nuisance of myself. My intentions are pure- I will use these powers for the good of everyone."

Fuku yawned, putting one leg up over the arm of the chair to lean to the side. "Well, I won't."

Keiko sighed. "You lose nothing in the exchange."

"My time."

She glanced around a moment. "There are no challengers here. You cannot leave here in case one answers the bluff while you are away, and you cannot rescind the standing challenge because you don't have a posse to leave with." Fuku groaned, rolling his head around. "Kamaitachi always travel in groups of three, no? You are only one."

Fuku vanished and re-appeared in front of Keiko faster than her eyes could blink, pointing his staff at her. "You've a lot of nerve, kitsune."

She jumped to the side just as the wall of force blasted past from Fuku moving so quickly. "I need a teacher, that is all. Not food nor shelter, just a lesson. I can do chores for you as pay...ment..."

They both looked around at the virtually empty temple.

"Yea, I will sick you on the dishes and laundry I don't have." He sighed again, heavily. "Fine, a test to see if you are even worth the effort." He clacked the staff down, placing his other hand on his hip. "In this shapeshifted form- what part of this form is NOT an illusion? Of course, it could be a trick question and all of it is an illusion, heh."

The paused a moment in concentration. "Hat and staff."

Fuku's brief smile faded and he bent over in surprise. "Seriously? How did you figure that out?!"

"When you moved toward me twice now, both times you were lowering your arm when you stopped- you were raising it to grab your hat, because it cannot keep up with the rest of you. If your outfit were not an illusion it would explode off of you from air pressure alone when you move at those speeds, so it cannot be real or you'd be immediately naked. The staff was a guess- but if you carried anything real it would have to be something practical otherwise you would not bother, and the staff serves as a weapon."

Fuku grumbled- his form shrinking so fast it looked like he vanished into his own clothing, then the cloth spiraled and collapsed into him as well as he resumed his true form, but then skittered up his staff before it could fall over and clung to the top of it- balancing so it remained standing. "Fine, I have time to kill I guess."

Fuku had Keiko shapeshift into what forms she knew to see if he could determine the problem. The first and most obvious problem he noticed was that she is simply trying too damn hard.

"You notice in my human form I am always heavily dressed- because I don't shapeshift my body. I don't need to shapeshift my arms if no one can see my arms in the first place to know what they look like. If most of my body is buried in illusory cloth- then I don't need it to look like anything because no one can see it. Don't want to shapeshift your hands? Put your hands in your pocket- problem solved. Can't think of a human face that isn't a copy of someone in your immediate area? Wear a mask!"

Keiko was trying to turn her entire body into the entire animal, but 99.9% of the time; there is no reason to do that. Hopefully no one is going to cut her open to know what her insides look like, so trying to shift them into another form is pointless, because no one knows what they look like anyway.

"Start simple." He kicked his staff from the side as his body suddenly grew massive, the staff twirled around and landed balanced across his back as Fuku was now the size of a horse!

Keiko matched that easily enough. This illusion is done using ones aura- what appears as a massive version of their body is actually just their aura shapen into the form and made visible. Fuku then transformed his forepaws into the forelegs of a deer, and then his hind legs into those of a horse telling Keiko to follow suit.

The trick to reducing the effort needed to shapeshift is knowing just how NOT different the forms are. Some animals seem quite different from one another, but usually; they aren't. You know how many vertebrae a horse has in its neck? Seven. Know how many a human has? Seven. A fox? Seven. A whale? Seven. A giraffe? Seven. Every mammal as the exact same number of bones regardless of how long the neck is- well, except a sloth but there are no sloths in Japan anyway. Even something drastically different in appearance like a whale's fins- look at its skeletal structure; it has fingers. It has three big fingers and one teeny tiny finger and thumb- it's exactly like a hand except the muscle and flesh has grown over all of them to make it a fin.

Keiko started with the deer hooves since they are closer to paws. Her claws grew massively first, then started to bulk up and become more geometric in shape. Instead of small translucent hooks they became large and blocky, turning to rounded triangles in shape. The bones in her paws compressed and started to fuse into a cannon bone, extending the length of her overall arms forcing her to lean back on her hind legs more because she is lopsided now. As her arms lengthened only her middle two digits progressed, the other two remained anchored in the position they already were, and then drew back and closer together as her paws almost looked like they were folding as they lengthened and evolved. What had been the outer two digits were now dewclaws! The hoof segments on the middle two expanded even greater; doubling in size and stretching the digits they are attached to, wide and squat in order to host such giant 'nails' as they became the primary hoof segments.

Keiko clicked them back and forth on the floor a moment, showing them off to Fuku who just rolled his eyes and told her to get on with the next set. A cloven hoof has four segments- just like her paw has four digits, so it isn't much of a leap between one and the other. There is only one cannon bone instead of a complex cluster of dozens of bones that a paw would have, but also the bone is giant in comparison- so she just fuses the existing bones together rather than actually change the number she has.

Now if she were to follow the evolutionary route- doing a horse hoof for her hind legs would take some real concentration because she would need to regress a lot of features she has off of it- because it's incredibly simple in comparison. Much, much fewer moving parts... which also makes it a lot sturdier, and much, much harder to break. Like she learned with the deer hoof however- she did not need to change the number of bones or complexity of her limb; she just needs to make it LOOK like she did. Her nails once again bulked up, but as that happened her digits started to merge together! From the crook of her digits upward they fused their skin, then muscle, then bone. What had been four digits became only one, and her growing claws fused into one giant hoof. The hoof grew into a huge arch and she leaned her weight up onto it as it grew a bit longer to lift the flesh of her mono-digit up off the ground and out of harm's way.

Keiko pranced on the spot a moment, trying to mentally brace herself to use these new limbs. Hooves are basically evolved fingernails- so ungulates walk on the veeeery tip-tops of their digits, balancing on their fingernails.

Fuku shifted back to his true form and hummed about what to give Keiko next; settling on scales. He told her to transform her tail into that of a fish. She was about to ditch the bushy fur on her tail but he quickly corrected her on that. Fur and hair is actually quite a bit of keratin- it is basically made of the exact same compounds as flesh only condensed. So up the keratin value and change the shape of the hair and you have something like a fingernail... a scale. Rather than try and replace her fur with illusory scales she should be turning her fur INTO the scales. Their biological composition is almost already the same thing! All she needs to do is change their shape and its already basically made for her. So she fused her fur together into sheets that billowed rounder toward the ends, turning into the overlapping fan-shaped scales of a koi! The flesh and blood portion of her tail expanded massively, at first in girth but then length too. It grew to the ground behind her and then still longer, slithering around on the ground before the flesh on the end billowed out into long, thin sheets, overgrowing the body of the tail considerably.

Because the scales are flat and spread out, they cover more space than they would standing up as hairs, so the coat of scales was able to expand to cover the overgrown tail easily without Keiko actively needing to monitor how many she had, and if she were properly covered. Any part she utterly lacked would need to be shapen from her aura- but thus far Fuku has taught her how to make all of these changes using what she already has by default. Keiko blushed as her privates tingled and became squashed together. In order to host a tail properly sized to her current body; her anus was shoved forward by the expansion of the tail base, squashed into her very dark brown vulpine vulva, and then the two openings fused together to become a cloaca! The tail expanded to take up the entire pelvic floor with muscle- forcing the cloaca forward and pulled tight horizontally across its base- acting as a divide between body and tail. For a moment it was oddly shaped, due to the vixen's puffy, projected labia being pulled into a narrow leaf-shape by the rest of the passing changing, but then she regressed her nether lips to better fit. Once it was fully internal she did not need to worry about what shape it was in- because like Fuku told her; if no one can see it, it doesn't matter. By the time it stopped growing it was a colossal version of the beautiful billowing tail of a platinum butterfly koi- the virgin white of her tail's tip overtook the scales.

Keiko kept half, bowing her hind legs before correcting her posture, because she is not used to the weight of the tail. It is quite meaty, and meant for travel in the water, so it was sort of dead-weight in this form. Fuku chuckled at her mixed up form.

"Alright... for body we need to go with something that is actually fairly different. Oh- I know, weasel! Us ermine have very long, very flexible bodies. Just... remember to extend your whole torso, not just the midriff or you'd might as well turn yourself into a meat noodle. Without a long rib cage to go with it- you won't have enough structural integrity to hold yourself up."

The change itself was easy enough- just take what she already has and make it longer, but transforming while standing up forced her to shuffle around quite a bit and was likely why he went with this change. Making her body longer forced her to shuffle her hooves to stay standing, but concentrating on her footing caused her to stop transforming. Fuku explained that in order to transform quickly she will have to anticipate how much space her transformed state requires and how she will need to move to take that shape without being forced to stutter the changes. Most of the time yokai shapeshift to get out of or get into trouble- turning into a new shape doesn't help in either of those cases, if they see you transform. More than not; you will lack the time to transform casually on your own time.

Fuku circled her, observing her work with a nod but nothing more. Weasel and tube-fox are often mistaken for one another, so fox are not exactly wildly different from weasel. One has tiny round ears and the other large pointed ears, one is about ten times the size of the other... but at a glance at least they are quite similar. Even their coloration is quite similar- the fox with orange-red fur, while weasel have brown-red fur. Both have white undersides. Fox have white tipped tails while the weasel have black. Fuku's tiny paws are more hand-like than her s in their default and while they have white fur- the fur is fine enough on his fingertips that you can see the pink of his skin through it, and his palms are candy pink.

The naked flesh in the trench down the left side of his face will be pink eventually too- but it's a puffy, irritated red still. He can shapeshift into a form with two working eyes, but doing so will be dividing the optical nerves of his existing eye, not creating new ones, which will strain his vision and likely give him a headache quickly. That is why he retains the scar in both his true form and his default human shape- it is far too difficult to shapeshift around it, so he keeps it in all forms. It isn't worth the effort to try and cover up. Fur will never grow there again even after it fully mends, and his eyesight is gone from that side. The wound is still pretty fresh, so Fuku often pets it gently with his hands unconsciously. There is currently almost no feeling in the wound itself, because the blade cleaved straight down to the bone, so the flesh knitting itself back together over the ravine hasn't connected any nerves yet.

Using shapeshifting; a yokai can also force-heal themselves in the heat of battle. If you are wounded severely mid-fight you can simply transform into a shape that doesn't have the wound. That doesn't make the wound go away- but you can't bleed out of a hole that isn't currently open, so while you keep the guise up you won't bleed to death at least. You will still be in pain of course- and still be draining energy profusely. Once you run out of energy to fight or keep the illusion up- concentration breaks and you lose the shapeshift and revert. So if you haven't finished the fight or run to safety by then- you're fucked.

Fuku told Keiko to go with a series of transformations with her head- deliberately using a mix of many different things . The beak of a crane- the long ears of a lop-eared rabbit, and turn her fur to match the weasel body. The ears were easy enough- just much longer version of her existing ears basically. The fur was easy because she already had the appearance on her torso, so she just encompassed more of herself. The beak however was a bit trickier. It is the same as in her robin form which she has used many times in the past but much longer- and the transition is tricky.

The beak is essentially her fangs in a different shape. Her fangs fuse together and project out, getting more and more narrow as they act as direct extensions of her jaw. Her glossy black lips stretch thin creating just a barely visible seam between the beak and the rest of her face! The structure of the beak also backfires into her muzzle to make more beak, causing the fur to regress with the flesh over it, exposing more of the bone of the beak. It made several dull clunking sounds as it compressed, causing her entire head to jar abruptly with the movement of the sudden bone compression. A crane's beak is much more narrow than the muzzle of a fox after all.

Fuku's smile grew as he watched her carefully. It almost looked like an optical illusion because her shape shimmered and shifted for only a second here and there. For a moment her fur color mocked the feathers of a crane, then back to weasel. Then divots appeared on her back hooves giving it several points as if it were splitting into claws, but then they fused again. Her size lurched, almost reverting while retaining its shape but then shuddered back to full size. Suddenly pulling herself back to her full enlarged size caused Keiko's concentration to falter and her beak started to re-compress back into her head, and the flesh shove forward as if being forced outward to make room for the beak collapsing partially!

"BOO!"

Fuku yelled abruptly and Keiko gasped and her entire form collapsed almost immediately- returning to her true form so quickly that she was mid-air thanks to the size different, and fell back to the stone floor hard, winding her.

Fuku burst out laughing at her attempt to hold the shape. It was far too complicated for her to concentrate on all of it, Fuku had just been waiting for the moment her concentration gave out so he could have a laugh. He also motioned over to a scroll on the floor now with ink splattered onto the stone around it- he had drawn a sumi-e illustration of her absolute mess of a hybrid form, so he could have a laugh at her expense later on too.

She blushed and lowered her ears. "When the heck did you have time to-"

"Oh please. I could have drawn twenty more paintings in the time it took you to ask that question. Nothing is faster than the itachi."

In spite of taking every opportunity to fuck with Keiko and laugh at her shortcomings- Fuku persisted in his training her. Every day he would task her with a new form and then drop her off in a place where that creature existed naturally- so she could see how well she fits in. How loose her illusion could be while still working, and most of all- holding the shape for a length of time while also DOING things to blend in. A transformed state is useless if she cannot do anything while transformed, she might as well just turn into a statue every time.

Fuku told her to do a bit of role-playing in her head. She needed to immerse herself into the role. Keiko still exists, of course no matter what role she molds herself into- but in the moment she is not herself, she is what she has turned into. Yes she still has her memories and her emotions, but now they belong to a horse, or a fish, or a bird. She is still Keiko, but Keiko is now something other than a fox. Put your mind into the role, so you are not constantly at war with your own mental image. They are all living beings trying to survive in the same world. The bodies are not that dissimilar, the lives are not alien from one another. Learning how to master many forms starts with realizing how few differences existed between them in the first place.

Fuku trained her for a week- eventually moving to an even more active training to test both himself and Keiko. Fuku set Keiko to evade him. Obviously- she cannot possibly move fast enough to hide from Fuku; he is so fast that he can check literally every hiding place in an entire village in the span of a half hour to find her regardless of where she hides... unless she does not look like herself. Fuku doesn't have as much experience in chasing after an opponent who can also shapeshift- and Keiko can put her own skills to the test, trying to act normally as something she is not supposed to be. She has to not only look like something else but also act like it enough that Fuku will not know the difference. Keiko also took on a few inanimate forms- those were easier because you do not have to worry about moving; inanimate objects do not move.

Fuku is not an especially good teacher. He is very good at shapeshifting naturally simply from being born itachi- but that doesn't make him a good teacher. He isn't great with putting his thoughts into words, and he is so skilled with shapeshifting by default that it has become second nature to him. He does not really need to ever think about shapeshifting himself, so if he doesn't think about it; he doesn't know how to talk about it in order to tell anyone else how to do it. It is muscle memory for him. After a week; Keiko had shown clear improvement, and the added confidence and experience of simply trying these different shapes was helping her immensely, but Fuku had already dried up any advice he could think of to give her.

After a week he took his human form, motioning to her to follow with a nod as he walked down the mountain from the high perch of his stolen temple. "Come, you've been doing a such a good job- let's get sloshed to celebrate. Been so busy babysitting you that I haven't had the time to get shit-faced in a while."

That was one major difference between Keiko and Fuku. Keiko tries to be well-mannered and always tries to help anyone she encounters. Fuku doesn't know what manners are, and doesn't even hunt for his own food most of the time- he steals human food. He can move so fast that he can steal the food right out of someone's hand without them realizing what happened. Wouldn't they get ripped off their feet by the pressure vacuum from him moving past them? Not if he moves back the same way- and negates the pressure shift with an equal shift in the opposite direction. All the person feels is a slight breeze at most and suddenly the items in their hand vanish into thin air.

In the time they have been here though- Keiko managed to help several people in the guise of another human, and has managed to earn herself a little bit of money- so she can pay for Fuku tonight. Fuku is going to drink regardless- if she doesn't pay for him he will just steal it anyway. Human laws mean nothing to him- he is too fast for them to ever catch in the first place, and as far as Fuku is concerned; if you are skilled enough to take something, then you earned it, and it belongs to you now.

In his human form; Fuku is handsome but rather rugged as well. His facial hair is scruffy and mid-length, as is his clearly uncombed human hair. He wears a full normal outfit, but then a cloak over that, and then a hooded shawl over that, and a wide-rimmed conical hat made of smoked bamboo- with a cleft in it from the same blow that took his eye. So very little of his actual human body is ever visible- only his hands and half his face. This allows him to be lazy with the shapeshift because he is hidden in the clothing- and the clothing has so many layers that if one part accidentally merges into another for a second or two, no one is going to be paying enough attention to notice.

Normally Keiko would be against getting drunk- especially in the company of humans as they entered the local inn, but Keiko has been trying to loosen up. Under the occasional tutelage of Uzume the kami of the dawn, as well as a fellow fox named Genki; Keiko has also been trying to train herself to have more fun with life, relax, and play around. This also served unintentionally as good training- because getting drunk will severely damage her ability to concentrate- and her ability to shapeshift is entirely reliant on her concentration. On the other hand; surrounded by humans makes it dangerous and puts the pressure on. If her transformation fails- the humans will see her!

Fuku is fun to be around, so being with him while he gets drunk too made it a pleasant experience regardless. He is a bit of a crude old bastard, but Fuku is a good person at heart; Keiko can see that plainly. He is quick to laugh at her errors and taunt or insult her, but he is equally quick to smile when she succeeds, and offer her help to improve. Fuku respects skill and effort- and Keiko may just have more of that than anyone Fuku has ever met.

In human form; Keiko surprised and annoyed Fuku by claiming to be his daughter while they were there. He growled under his breath as she grinned at him and called him father proudly. She knew he could not argue because it would make them seem suspicious to the humans, and he certainly never bothered to come up with any sort of cover story. Her human form and his certainly looked like they could be father and daughter more easily than siblings, and neither of them were bold enough to claim they were lovers. He also always cringed when she called him her teacher. Even when he is being a nice guy- he doesn't want to be called out on it! He has a reputation to uphold!

Thanks to her teasing though- Fuku made to attempt to help bail her out when one of the other guests at the inn starting coming onto her. They were both drunk and Keiko couldn't think of how to let the guy off easily, fast enough to do it. Fuku just grinned at her as she reluctantly agreed to sleep with the guy in his room at the inn. Oh well- he is drunk and easily tricked. She will just transform back to her true self when his back is turned and slip out the window onto the roof and away into the night. Except the moment she tried, she realized the window was firmly sealed and she could not open it! The door was locked by the man so she could not get out quickly that way without being seen futzing with the lock first. Fuku was on the roof just outside the bedroom, preventing the window from being opened with a devilish smile on his face.

Keiko was nervous a moment, but her nerves were softened quickly again thanks to the help of the alcohol. Well... it isn't the end of the world. Some over-eager young man travelling as a merchant, drunk and ready for love? Maybe she should just give it to him? Her transformation isn't complete enough for him to make her pregnant, and it would be a bit of fun. She just shrugged to herself. Look at it this way- it is good training. Now she has to keep her transformed state up while having drunken sex.

Keiko just got down onto the bed as the man stripped himself off, trying to look as confident and manly as possible, while also being so drunk that he almost tripped himself several times taking his clothes off while standing up. Keiko lay herself down on the bed, her long raven hair fanning out on the pillow around her head like rays from the sun. Her kimono already a bit too big on her and now fallen loose that she is laying down. She let the man untie her obi and open the kimono to reveal her supple form. Though her kimono is very simple and of common colors and make; her default human body is very beautiful for when she needs to use it to seduce. Her mouth narrow but her lips vibrant and plump. Her skin porcelain and soft; smooth as if she had never done a day of work in her life. Her breasts are pert C cup hills with brown areola and nipples so dark they nearly look black- which is actually also true for her flesh tone in fox form as well. He climbed over her and placed his hands over hers- pinning her arms up beside her head as he thrust into her.

He explored no foreplay, and clumsily worked up to speed almost immediately after getting into her, thrusting with enough force to jostle her tits up and down her chest. Hmm, but that is no fun- he will shoot far too soon at this rate. But Keiko's friend Genki taught her a different way to use shapeshifting. If she uses her power of possession to place some of her own aura into another person- she can transform them instead.

The man grunt as his balls started to droop further, pulling his scrotum smooth as their size and weight increased! His foreskin thickened and then his cock from the base up expanded in a slow surge! When the expansion got to the head; his glans turned purple from blood pressure, pulled entirely smooth and grew out in a large mushroomed head- the corona now catching on and tugging at the muscle ribs of Keiko's inner vagina when he tries to pull back. Her breasts started to firm up more and stand more and more round in spite of her being on her back- giving him more of a show to keep him distracted. They swelled into almost perfect half-spheres before they expanded outward, growing in size till they were each like a cantaloupe! Her areola now looked disproportionately tiny on her enlarged breasts- but Keiko herself was too drunk to notice the minor detail.

With her increased pleasure; she also increased his own, so he was still approaching orgasm too quickly. And she just KNOWS he isn't going to tend to her after he blows, so if she doesn't climax too- this will end very one-sidedly. Keiko grinned and pushed her arms up THROUGH his own like she was a ghost. The man was confused and without her arms to brace himself properly on he fell forward and fell INTO Keiko as she fazed through his body- using her power of possession to take it for herself. The only way she can force him to cum when she does is if they are the same person.

Whatever awareness his drunken state left him in would remain active in his brain- but Keiko was now in full control of his body so he could no longer control his own actions. She smiled down at the cock between his legs and six dark brown nubs started to form on his midriff as her own features manifested on his body, shapeshifting both of them. She summoned her sixpack of fox teats onto his body, but then moaned and leaned back as the flesh behind them swelled with growing fat- forming human breasts behind the teats! Keiko got up onto his knees and leaned back with her hands on the bed behind herself to watch the breasts swelling out!

The veins in his groin grew fat and dark and Keiko felt a gentle but powerful rush of pleasure growing in it as her magic went to work on it next. She wanted so badly to touch it and amplify the pleasure but knew it would quickly overwhelm her, so she kept her hands off and just chewed her lip in arousal for now. The balls swelled as well as his foreskin becoming puffy and the skin thickening greatly! The scrotum and foreskin turned almost black as the skin became denser, and then with the feeling of peeling tape off your skin- his shaft started to immerge further from the foreskin than it should be able to! More flesh peeling off of the old flesh as his foreskin started to pull tight at the base drawing it closer to the body as it began to fuse- having transformed into a sheath!

A powder-soft coat of black fur started to grow out across his balls starting up the cleft but then spreading across the entire surface and up the sheath. His hair color caused it to grow in black instead of Keiko's vermillion color. Keiko leaned him forward quickly when the tail bone wiggled, shoved out, wiggled more, and then erupted in size before a fine coat of black hair grew in and then in a burst erupted into a gigantically bushy fox tail- sized up to match the human body! The fur is voluminous enough that someone could easily use the tail as a pillow. Moving into that position caused the man's balls to squish against the bed and rock further forward, pressing on the sheath and increasing the tension in the shaft, making it feel even better as it slides further out!

The shaft swelled fatter toward the end making it club shaped as the skin turned progressively more red. The veins became less projected but more numerous as thin dark purple webs below the surface. The glans reshaped, inverting as if unable to keep up with the expansion of the shaft below- but the urethra remained just as far out, causing it to project outward as a rounded cone now! Keiko smiled and grit her teeth as the pleasure increased in sharpness. She pushed down on the sheath, squashing it into the divot between furry balls to feel the bulge growing inside! Bigger, harder, bigger again, forcing its way up yanking the shaft even more impossibly tight from lack of room to remain inside the sheath! With a slick sound the giant knot finally popped out, and shoved the sheath back to make way under it! Normally a vulpine knot is relatively subdued as their endowment in general in comparison to canines, but, Keiko is in full control of the shape so she can make it whatever she wants. The shaft itself stands at a staggering 22 inches long, as thick as her arm and a knot that looks like the dick tried to swallow two ostrich eggs at the same time and they got stuck on the way down.

Keiko shivered from the feeling, leaning back again to look at it in awe a moment. She completely forgot about the fact that this body isn't even hers- the man is going to wake up thinking he had the most insane fever dream of his life tomorrow. This dick is completely impractical- never mind a human, you'd be hard-pressed to find ANYTHING that can actually comfortably fit this phallus into them. But... she doesn't need to fit it into anything. It isn't for anyone else- it's for Keiko.

She lifted his butt to swing the balls free and straighten her legs as she leans back. The dick falls back, slapping against her and making her gasp and then stands back up off her by an inch and a half- turgid enough still to somehow lift itself. Keiko scoot his body up the bed and put his feet up on the wall over the pillow to lean her body back and wedged the giant cock between the six breasts immediately above it on her midriff! She just grabbed up the bedsheets under the man and started humping away, tossing her head back and forth squealing in giddy pleasure- her voice a bit hollow sounding because it was being projected through someone else's body. She could tit-fuck herself easily, hands-free. And not just one pair, but all three sets of breasts at once. The knot pressed into the lower cleavage but was too bit to part the firm breasts far enough from each other to wedge itself in.

When she started to approach climax she scoot even further up, bending her body further and reached down to hook her fingers around the underside of the knot and pull up- this is the most sensitive part of it. She only made tiny micro thrusts like this, keeping herself teetering on the edge of orgasm as long as possible. She finally hit climax through the man's body and blasted cum clear over herself and onto the floor at the foot of the bed.

Keiko felt his consciousness fade inside and realized he passed out from the climax, and the transformations to his body seemed to turn to colored vapor and lift off as Keiko emerged from his chest in her true form. She once again tried the window now that he was unconscious and she could make more of an obvious effort to open it than before, but it opened easily now. Once the action started- Fuku left to give Keiko her privacy- and already wandered back up his mountain.

The next day, Keiko once again set out onto the road to wander, looking for people in trouble that needed saving. She thanked Fuku for his training, and he pretended to be happy she was finally leaving him alone- though was sure he would miss her at least a bit. This would not be the last time they seen each other, and Fuku will always be one of only two people Keiko ever called 'teacher'.
