The teacher was late. That in and of itself was incredibly strange. From day one at the Canterlot School for Gifted Unicorns, punctuality was strictly enforced and ingrained in the minds of all the foals there. Being even a minute late often led to strict punishments, such as time in the isolation room, or several demericks at the very least. Sunny Days had never, ever heard of a teacher being late, much less seen it for herself. The little sky-blue unicorn mare fidgeted awkwardly as she sat at her desk, glancing nervously between her classmates. Most of them looked just as nervous, eyes locked on the door.
Had the schedule changed? Had they missed an announcement for a school assembly? Oh Magic, missing one of those would be really, really bad...
"What do we do?" Her neighbor to her left, a little grey mare named Dinky, hissed out, a small whimper following out moments later.
Sunny Days shrugged, trembling slightly herself, but feeling bad for her smaller friend. Dinky had been brought in during her elementary years, much like Sunny had, and had been a frequent target of the teachers' wrath. Being that her mom was allegedly a pegasus, and one with mental and physical problems at that, she wasn't one of the vaunted purebloods. Sunny thought the favoritism showed to the sons and daughters of the Nobles was totally abhorrent, but... well, it had always been that way.
With a crackle of passive magic, a field washed over the classroom, and every student stiffened in surprise, little purple sparks erupting from each and every one of their horns. And with each little pop and snap, a strange heat began to fill the little sixteen year old mare, her bright purple eyes widening in shock. She... couldn't be going into heat. It didn't come on that suddenly, and her schedule didn't put her in estrus till the next month. But the heat and the powerful, burning need... it was like Estrus ramped up several fold!
Doing her best to hide her scent and the marks of her quickly budding arousal, Sunny Days shifted her rump in the uncomfortable wooden seat, mentally cursing the soft white panties and the skirt she, like all mares and fillies, were forced to wear. While it certainly covered everything and helped with modesty, right now, the softness was rubbing riiiiight at a sensitive spot. Glancing around sheepishly, the young mare was surprised to find almost all of the other students squirming in nearly the same way. On her right, a grey-furred colt whose name she had been too shy to learn, was doing his best to hide the thick bulge showing in his pants. But Sunny was very sure that she could see some mottled pink and black peeking free and-
Yelping quietly, Sunny jerked her head forward as the door slammed open. Yes, a teacher, fin... a...lly... A tall, purple furred unicorn mare happily trotted inside, humming quietly to herself. Her streaked purple mane was pulled up in a classic bun, and she scanned the class curiously, dainty glasses settled on her nose. She was dressed like a normal teacher, with a buttoned up white blouse and sensible dark skirt... but this new teacher was also, easily, the hottest she had ever seen. Sunny Days worried her lower lip with her teeth. She had long since come to terms with her attraction to the pretty mares around her, which could be just as strong as to the colts she knew and hanged out with. Come to terms with, and buried down with a passion. Acting on those urges was not an option, not when it could get one sent to a re-education camp out in the badlands. And if Sunny thought her school strict...
"Good afternoon, class," the new teacher said warmly, giving a teasing smile to each of them, "I apologize for being late. I had a few... things to handle. My name..."
She turned to the blackboard and gripped a piece of chalk in her magical grip; with a simple flick of her tail, the teacher's skirt rose up, giving every student a flash of their pantie-less teacher.
"Is Miss Sparkle. I'll be your new teacher from now on."
She grinned back at them, and a stunned little Sunny was absolutely certain she would pay extra special attention to this lesson. And, unknown to each of the colts and fillies in the room, their eyes began to shimmer with a soft purple light. Giggling quietly, Twilight Sparkle turned to face them all again, an excited grin stretched across her muzzle.
"Little Dinky... yes, you. Please, come to the front of the class. I'm going to need an assistant for today's lesson..."
****************************
The Canterlot School for Gifted Unicorns was one of the most well-funded institutions for education in the entire kingdom, and they had diversified well in teaching areas for students. One of the biggest upgrades to the school had been a fully furnished and lovingly tended greenhouse, settled in a secluded corner of the campus. Looked after by thestral "servants" and gardeners, students often have botany and biology classes there, studying and learning about the various uses and dangers of the plants.
"Hey, where are the batponies?" someone asked, and Midnight Haze blinked, glancing around as that thought registered in his own mind.
Midnight and the rest of the class had arrived perfectly on time, as per usual, and the greenhouse was usually a buzz with activity- the thestrals rarely stopped watering or pruning, or the teachers would crack down on them harshly. There usually was an earth pony mare among them, but she also worked in the school's orchard... still... It was very unusual for the thestrals to risk the teachers' wrath like this.
"Probably out hunting," someone spoke up, and got a few laugh for the not funny quip, not noticing the tightening of Midnight's jaw.
His parents had been thestrals. He had just been "lucky" enough to be born with a horn, which had allowed the government to take him into their custody, and be all but raised at the Canterlot School for Gifted Unicorns. He did get letters from them from time to time, but never a care package. Those were always held back, he was certain. With a grumpy huff, Midnight brushed a lock of his blue mane out of his eyes, determined to ignore his ignorant classmates. He didn't expect them to know that thestrals rarely ate meat- fish, just like pegasi, if they could get it, but nothing red. They rarely learned about the other races in biology class, after all.
"It smells really good in here today," Silver Chime, a small first-year, whispered from beside Midnight, smiling dreamily around at the all the flowers.
Blinking curiously, Midnight took a deep breath, and his eyes widened slowly, purple flashing unseen in the back of his eyes. It... did smell good. Really, really good, like the best perfume and colognes mixed together with... something... Something amazing, and something very new to the greenhouse. There were definitely new plants in the greenhouse; massive blooms that seemed to slowly shift colors, from blue to white to red... Every color of the spectrum seemed to flash before his eyes, and Midnight found himself walking towards one of the blooms. In his periphery, he could see little Silver Chime walking towards a new pitcher plant, one large enough to hold several ponies in its depths.
The bored chatter was beginning to die away as more and more students began to fall under the spell of the plants around them, not noticing the grinning peach-colored mare that blended into one of the stalks of a tree that had grown up in the middle of the greenhouse. Not noticing the pony shaped lumps in the middle of several Giant Venus fly traps, squirming softly and giving muffled, blissful moans. None of them spotting the gleaming red eyes hidden in the canopy, toothy grins catching the light.
One of the older students, the one who had accused the thestrals of being out hunting, let out a muffled cry as a shadow swept down and yanked him into the tangled undergrowth. Hot Shot cried out in surprise as vines and small thorns tugged and pulled at his pelt and mane. His blazer was torn off easily and, with a small giggle, a fanged maw darted down to cut through his belt and pants, ripping them off as well. Hot Shot was shocked to see that his cock was rock hard, dripping pre in his arousal. He was also more than a little shocked and frightened to find himself in the hooves of no less than a dozen grinning, red-eyed thestrals, led by a giggling, green-eyed thestral who was far larger than all of them.
Her soft hoof traced slowly up his shaft, and a little noise of suppressed pleasure bubbled out of Hot Shot.
"You were right about one thing," she whispered, one of the thestrals' hooves reaching out to stuff itself into his mouth and block out his frenzied sounds, "We WERE hunting. Hunting for a new plaything..."
Nearly too fast for the colt's eye to follow, the yellow thestral slid her throat down his cock till her muzzle was firmly pressed to his stomach. Pleasure rocketed up his spine, and he arched against her so-tight, squeezing throat... only to squeal as another cock came a-knocking to his backdoor. Tensing up, Hot Shot began to wriggle frantically, but the thestrals around him were far stronger than he. Inch by inch stretched open his bottom, and a little gurgle of pain-pleasure worked out of his blocked muzzle. The male behind him almost gently wrapped his forehooves around Hot Shot's barrel, and he began to happily lap and nip up his sensitive ears.
"Don't worry kid, I'm gonna go slow," he teased, and the thestrals around him giggled.
Too focused on the plants to be aware of Hot Shot's predicament, the other kids of the class were now studying the new flowers and pods in depth. Midnight Haze was smiling dreamily as he rubbed his cheek along the inside of the flower's bloom. Little cilia tickled his sensitive fur, and the wonderful scent clouded his senses. His nose nudged the thick stamen of the flower, and a puff of pollen quickly clouded around his lips and nose. Blinking and trying not to sneeze, Midnight opened his mouth and quickly lapped his nose clean... and gave a loud, orgasmic cry as pleasure ripped through his body like a lightning bolt. The pollen had no clear taste, but each bit of dust on his tongue filled his body with euphoria. And desperate for more, he quickly nudged the stamen again, lapping frantically along its strangely thickening length.
Silver Chimes had climbed up the side of the giant pitcher with a sticky hooves cantrip, her eyes locked firmly on the dewy lip of the pitcher. The scent that had lured her, a sweet melon-y scent that reminded her so much of the home she had not seen since she was a child, was thickest here, and she desperately leaned forward to lick along the lip. The taste was exquisite; like the ripest melon that her earth pony mother had ever grown and given to her. Whimpering softly and trickling her own juices down the pitcher, Silver leaned into the pitcher, licking up every bit of dew she could reach. Just like the pitcher wanted. The side flexed once, and Silver gave a surprised squeal as she fell inside into a small puddle of the dew, which quickly coated her small body.
A warm tingling slowly rose around her body, focusing especially on her sensitive teats, her untouched plot, and her strangely sensitive hooves; but the tactile sensation was nothing compared to the one taking over the young filly's mind. Silver Chimes had always been a very shy, very nervous young filly, knowing that she had little strength in the magical arts, and that her special talent lay in making music. The art department at the School was hardly lacking in funding, but the competition inherent in it was... nerve-wracking to say the least. And that sheepishness to stand out had carried over into all of Silver's life. But now, it was as if all of the tension in her thirteen-year old mind was draining away. Her muscles slowly relaxed, and she flopped down into the dew, a satisfied smile on her lips as she lapped and suckled at the sweet fluid. Small tendrils from within the pool began to crawl out and wrap lightly around Silver Chime's hooves, but she paid them little mind, only giving soft, pleased noises as the tendrils engulfed them, cilia massaging the sensitive skin. One especially large tendril carefully enclosed Silver Chime's nose, giving her specially treated air to breathe as the dew began to quickly fill the interior of the pitcher. From outside, Silver Chime's silhouette was swept away in a rush of fluid that bloated the pitcher's outer body.
Unbeknownst to Midnight Haze, the flower he was suckling at had begun to close in on itself, and him. Closing firmly, all that could be seen of the colt was his wriggling hind legs, but he paid little mind to that. The stamen was his whole world now. Shaking heavily, with his lower body coated in his own cum, Midnight Haze frantically licked and nibbled along the outer edge of the flower's wriggling stamen. It was only when he leaned up to suckle at the wide tip of the stamen did things suddenly change. With a surge of movement, the stamen plunged down the surprised colt's throat, the numbing agents in the tip of the stamen suppressing his gag reflex, while a special tendril broke off and slid into his lungs to keep him breathing. It was an odd sensation, one that left Midnight frozen as the stamen went deeper and deeper, curling and coiling inside his lean body. Managing to turn and look down, Midnight stared in awe as he watched the stamen's progress through the bulges in his stomach. How was he not dead?
A strange pressing sensation began to fill his ass, and he let out a muffled, strangled cry as he felt his innermost depths beginning to stretch out. The sensation was somewhat painful at first... until it rail-roaded over his prostate. Midnight squealed loudly at the surge of pleasure, and a thick spurt of pre launched from his rock-hard dick. The stamen was covered in little bumps, and each one left the little unicorn quivering and mewling frantically, on the edge of release. It was only then that he noticed the end of the stamen hovering in front of his eye, the little opening in the middle almost seeming to wink at him.
No way.
Coiling back around, the stamen's center eye opened wide and engulfed Midnight's cock and balls in one fell swoop, tightening around them quickly. Thousands of cilia, very warm and constantly moving, began to stroke and massage at every square inch of Midnight's colthood- there was even a small patch inside him that was teasing and squeezing his engorged prostate. The pleasure was more than anything Midnight had ever managed with his hoof, even with the aid of lotion and a stolen magazine. As he moaned and wriggled frantically against the stamen, an orgasm was ripped out of him within seconds, his eyes rolling back as he felt the warmth of his very essence travelling through his body. Little holes in the stamen dripped some of the cum onto Midnight's tongue, and he flushed ferociously as he tasted his own salty seed. And as the suckling continued, the realization hit him like an earthquake: he had no control whatsoever. He could be stuck in this plant forever. And he wasn't sure if he cared. His sinful, bliss-filled cries carried out of the plant, joining a cacophony of others around him, as Applejack's plant kingdom found its first source of hosts and energy.
Giggling softly to herself, Applejack watched with amusement as Fluttershy's band of thestrals pressed Hot Shot's muzzle into a pool of cum dripping from one of the plants- the well-fucked colt automatically began to lap it up, quivering heavily as the heavy male atop him let out a deep groan, signalling another thick shot of cum to join the others in the colt's bulging belly.
"Ah hope Twilight is havin' as much fun as we're havin', sug."
*****************************
"That's it, class," Twilight was purring as she sat at her desk, grinning slyly, "You have to keep a dual-focus. Pleasure your partner, but focus your magic on my target. That's it..."
Reaching down underneath the desk, Twilight let out a pleased groan as Dinky's quick-learning tongue focused on her clit, and Twilight's unclad hoof gently traced little circles around her soft ears.
"You're doing such a good job," she whispered down to the blushing little filly, "Your mama is gonna be so proud of you. Mmm..."
That got a perky smile out of the blonde filly, and she eagerly suckled at Twilight's juices, utterly addicted. Her eyes were a brilliant purple, just a few shades darker than her pelt color; Twilight loved that color. Adored it, really. All over the classroom, the students' eyes all glowed the same uniform color, attention locked on the glowing red magical circle on the chalkboard. Dual-focus had been a lesson that Twilight had particularly enjoyed with Princess Celestia, though she felt that her own method of teaching was both more challenging for the student, and a little more fun. It was certainly difficult to focus on channeling magic when pummeling, or being pummeled, in sex for the first time ever. All the fillies and colts had been quite shy, but exposure to the lust magic permeating the school, and the pheromones from the greenhouse, had left them quite pliable. Seeing little Dinky eagerly licking at their teacher had set most of them off in a hurry.
Sunny Days was hunched over her desk, panting raggedly as she desperately tried to focus her impressive magical talents on the glowing circle; the colt atop her was fairly heavy and stocky, likely of earth pony stock in most of his bloodline, but his cock felt amazing. Cock. Just thinking the word left Sunny shivering in the delicious naughtiness. His heavy thrusts had hurt a little at first, but Miss Sparkle's magic was permeating all of them, and the pleasure had quickly battered aside the pain. And it felt like some of her organs too. Her tight tunnel clenched down on him with each thrust, her desk squeaking as it rocked back and forth. She hooked her hooves around the sides of the desk, giving a ragged little moan as the tip of his flared cock dragged over her g-spot.
"F-fuck, Sunny," the colt- Galaxy Eye, she thought his name was- groaned out, panting just as much as her as he did his best to stare at the circle, "I-I'm gonna... i-it's gonna h-happen again... Aaaaah!"
With a firm, deep thrust that left Sunny breathless, Galaxy came, cum spurting thickly into the filly and giving her already rounding belly just a little more girth to it. They had already had countless orgasms, the magic filling the room keeping them standing and going, but this one was different. Their cries were echoed all around the room, and surges of magic roared into the magical circle, its glare brightening ten-fold. As she looked over to her teacher, Sunny Days was awed by the look of supreme satisfaction and joy that had filled her teacher's face... and by the bat wings and dragon horns now sweeping out from her forehead. And then everything went red.
Twilight Sparkle cackled happily as the diabolic magic roared out from the circle, infusing each and every one of the foals; she quickly scooped a stunned little Dinky up in her magic and held her out into the wave. Screams ripped through the room, and Twilight's ears fell back a bit. The process, to start, was not pleasant. Obliterating and reforming the soul was an incredibly painful process- but when the fel magics filled them back up. Twilight's smile grew as moans and squeals began to replace sobs of pain and confusion, cum and filly juices splattered to the already soaked floor. She could practically taste the new power in each and every foal... They were not full devils like herself, but now devil-blooded. Powerful, faster, stronger... they were truly the next generation of Equestrian unicorns.
When the magic finally abated, the foals were settled down on shaky hooves, panting raggedly and staring at Twilight Sparkle with wide, uniformly crimson eyes. They were taller now, little runes running down their legs and necks. Giggling softly, Twilight stood to her full height, mane flickering in an unseen breeze as she looked them over with fondness.
"I am so proud of you all, my faithful students..."
