There goes the neighborhood
The world needs change and a certain bear man has just the thing in mind.
No one gave a second thought to the big brown bear as he walked down the street. He was dressed well enough for the area and despite no one actually knowing him, they all just assumed he was a guest of their neighbors. An attitude that suited the bear just fine, in fact it was an attitude that actively benefited his goals. His name, dear reader, was Kumakum and he was, despite outward appearance, anything but a normal anthro Grizzly. In fact he was hardly even a bear.
Some twenty years prior to the events about to unfold every human on earth had suddenly found themselves changing in some way. Some few hardly changed their bodies merely morphing into statuesque, visually perfect versions of themselves. Some of those who were changed had their genders altered, some of those that changed genders ended up as something not strictly male or female. There were hermaphrodites sporting beautiful bodies that had the best of male and female traits. There were women who had ovipositor pseudo-penises rather than a womb or vagina. Likewise there were men sporting decidedly female genitalia. Precious few had no genitals to speak of, their mouth becoming their primary sexual organ as intense kissing would trigger their asexual reproduction. The more common type of change though, was people becoming anthropomorphic animals. There were several levels of change; some only sprouted tails, had their ears and eyes change, and some even got horns as a result of the animal they had become. Others changed fully, bodies covered in fur, faces totally animal. shifting of hands and feet to paws, claws, fins, or hooves and genitals becoming more like whatever animal's traits they had taken on. A rare few become nearly indistinguishable from animals retaining only their ability to speak and intelligence. Some very rare cases became creatures never seen on earth before or only dreamt of in fantasy or science fiction. Among those beings were those with truly supernatural powers, some of which could be explained with modern science, some which defied such scrutiny. Regardless of what transformation people had undergone there was one universal truth of the changes, namely everyone was much hornier in the days and weeks that followed. Sexual preferences remained but many were forced to reevaluate their position.
Needless to say the sudden transformation had thrown the world into utter chaos. For five years there had been no one in charge. Families dissolved, unable to recognize each other. The borders between nations broke down. More and more people grouped themselves by what they had become, forming communities based on species. New borders formed eventually. Laws needed reevaluating and certainly rewording. Most systems of identification were null and void. Buildings needed to be torn down or modified to accommodate for the transformed. Things changed so utterly and completely so fast that it rendered all of history almost a farce.
The biggest lingering question of the event was what had caused it. Some declared spontaneous mutation due to the changing environment. Others attributed it to acts of the divine or the demonic. Many believed aliens had altered humanity all at once.
Kumakum was one of the more oddball transformed. He was presently using his abilities to hide the more curious parts of his being from sight. He was also one of the few people to know the source of the transformation. Which was not information he planned to share seeing as that knowledge was the source of his supernatural abilities. For you though the truth is that the wave of transformations was caused by the appearance of a being from another reality, his entrance to this world warped the fabric of existence. His departure from the world is what caused the transformations and those who had been nearby when he left gained the most power over the changed world.
Kumakum walked through the neighborhood unchallenged and unnoticed. Every few feet he reached down with his clawed finger and carved a symbol of an eight pointed star inside a circle into the sidewalk. Each sigil lighting up briefly before fading till it was time for them to do their work. Kumakum noted that this neighborhood featured a wide variety of species. Mostly herbivorous ones, but still more varied than the usual mono-cultures he spotted in his travels. There were sheep, goats, llamas, cows, buffalo, and horses. Kumakum considered it would make things very interesting when he was finished. This little neighborhood was built like a medieval city, a high wall of stone and steel marked the round perimeter. The center of the circular city was a vertical mall that served as the employment of most residents, and a hotel provided guest housing. From that hub four roads led out to four gates at the north, east, west, and south of the city. Kumakum had been marking this village for days and was nearly ready to enact his scheme.
Making his way to the top floor of the mall he drew the final symbol atop the roof and dropped his disguise. His fine clothes faded from sight like smoke drifting away. Large leathery wings like those of a bat unfurled from his back as a comically long poofy squirrel tail twitched through the air behind him. Kumakum grinned as the symbols he had drawn all around the area became beacons of vibrant purple flaring to life. The beams of light arced through the air joining to each other forming a chaotic grid as a dome of golden light washed over the town. The chimeric bear grinned as he felt the spell amplify his powers. A surge of lightning that set every hair on his body on end as he marshaled the power for his task. He reached out with his mind entering the panicked racing thoughts of the citizens one by one. He couldn't control them all, not even with this elaborate setup, but he didn't have to. It just took a little nudge to remind them of the first days of the transformation, the days where they acted without restraint or fear, the days they let their lust guide them. He didn't need to push hard, most of them were barely repressing their desire to go back to those times to give in to the animal desires once more.
Moving down into the mall proper he took pride in his handiwork, watching the mad coupling of the citizens. He caught sight of a hermaphrodite zebra sandwiched by a bull and a cow. The zebra's cock buried in the cow's snatch even as the bull held her by the hips, breeding her like there was no tomorrow. A young male zebra nearby was hunched over a large goat of the nearly feral variety, her cries of delight the only sign the boy wasn't just fucking an animal. Not far from that scene a pair of stallions were kissing passionately as they stroked each other off. On the next level down a herd of sheep boys had surrounded a buffalo girl and were either stroking themselves as they waited or in the midst of pounding her ass, pussy, and mouth. Two llama ladies had a goat boy pinned beneath them, mouth and cock forced to service them, not that he seemed to mind given his tight grip on one's thighs. Not far from that sight a cow woman was availing herself of a sheep boy who she had pinned to the wall as she took his dick for her own use. Nearly concealed behind a counter a llama was in the midst of devouring her sheep co-workers pussy, long thick tongue lapping over and into the other girls sex to both's delight. Couples formed at near complete random with no regard to things like age or sex on their mind. The males seemed particularly eager to take advantage of this cumming in a girl or guy and darting over to the next available single whether that was male or female. Some seemed to exclusively join the fun of couples already embracing. He watched with delight as a llama ran over to a pair of andromorph horses presently engaged in mutual cunnilingus and interjected his cock to the mix. A gynomorph cow grabbed a goat lady riding a sheep and in no uncertain terms instructed her to suck her cock.
Walking outside Kumakum reveled in the free flowing energies that the madly fucking citizens were making. it would be child's play to seize control of their minds now but that wasn't what he was after. The town was filled with a song of passion and desire that fueled him like gunpowder thrown onto a bonfire. The chimera bear roared in triumph as he reached into the minds of the citizens and pushed a new message. [BREED]. His command branded itself across their minds like neon, more than a demand Kumakum's magic swept over their bodies and made them ready for the action. Wombs quickened ready to be filled with seed and grow new life, testicles sagged, heavy with seed to spread.
Young boys and girls and those who were too young had their bodies mature. Their cocks grew hard, thick, and long as their balls grew to double in size and fill with their first load of cum. Breasts swelled heavy, soft, and warm. Pussies grew slick, warm, and hot, aching to be filled. Their bodies grew strong and tall, looking like adults even if they had only been tweens before.
For those more elderly, the process took back the years, saggy skin growing firm with weakened bones and muscles growing thick and strong once more. Addled minds cleared with the single goal of following the command. Dormant desires awakening as lusts stirred, Restored once more to the prime of their youth they set out to sate their burning loins.
Kumakum laughed as a young goat girl ran up turning her sex to him and wiggling her rump. Grabbing her, his long, thick cock wiggled from his sheath, laying against her backside for a second before he took her. The girl was tight, probably her first time not that the grizzly creature minded. He growled with desire, his prehensile cock working deeper into the girl, much to her obvious delight. He would stay long enough to see her grow heavy with his child, and then move to a new city and begin again. He wondered how far he could make this spell spread. The amplifying symbols turned from purple to red, the golden dome over the city shifting to a vibrant green alongside it. Kumakum failed to notice this change just as he was getting the goat girl pregnant. As he came there was a crash of thunder as his spell ruptured.
Kumakum blinked as he looked at the clear blue sky and wondered just what that was about. The goat girl on his cock kissed him before hoping away happily. The bear creature had no way of knowing that his idle thought had changed his spell into a sort of curse, now each and every person in the city was a living lust plague just waiting to happen.
