Several stories below the surface of the Nadiana School of Archaeology on the campus of SynTech University, Professor Jamie Morgan held her large, blue-scaled hands in front of her ample bosom. A bright blue light, so fierce it was nearly white, shone from a small gem suspended in between her spread fingers. The naga's wide, royal blue hood flared and stiffened as her eyes narrowed on the gem, focusing with intense concentration. Magical energy rippled from the stone like waves, but the naga, who kept her head about eight feet off the ground while her long coils often piled underneath her, didn't budge an inch.

Her dark forked tongue appeared, tasting the energy in the air, before retracting into her broad, flat snout, which featured a pale, soft skin rather than the rippling, royal blue scales covering her hood, head, and shoulders. The pale blue traveled down her neck and spread across her chest, which was held in by a v-neck long-sleeve shirt. The burgundy cloth pulled sharply around her large chest before squeezing in under the swells and against her thick, powerful core. With no legs, pants were not an option, so the professor opted for a simple loincloth-style drape around her “hips," though she classed it up by threading the burgundy cloth with a gold chain. The chain matched the amulet around her neck, a gold setting in which various gemstones shone, most prominently a large red ruby.

Flickers of light pulsed along the naga's hood, traveling through the band of gold that edged her head and traveled down her sides, about an inch wide, unvarying in thickness as it contoured around her coils further down her body.

Her tongue flicked once more, then she spoke.

“There. Once you are able to suspend the spell in the crystalline structure, you can later release it whenever you want."

The naga dropped her hands to her side and smirked as the short, four-foot-tall stoat facing her a few feet away scribbled copious notes into a black notebook. The stoat nodded furiously and glanced at her watch often, using it to take measurements of the air temperature, humidity, and other statistical data points. The stoat didn't say anything as she leaned over her writing pad, brown round ears flicking. She wore a simple black skirt around her hips. The hem of the dress draped around her feet and did a good job of revealing a long, downwards-facing bulge between her thick thighs. The wideset stoat wore a button-up shirt, a simple purple affair, with the sleeves rolled past her elbows. The upper six buttons were undone, so that the fabric stretched and the buttons at the front of the enormous breasts threatened to pop free at any moment. Despite being half as tall as the naga, the stoat's thoroughly impressive rack was larger any way an onlooker dared measure.

“While I appreciate your dedication to meticulous note keeping, Mina, it's important for you to experience this firsthand as well if you ever want to use these techniques yourself."

The stoat's ears folded back at the gentle reprimand. Her pen dashed off a few last words before she set it down and lifted her head. Her long and flexible neck added grace to her elongated torso, rising above her chest to carry her wide head and narrow-pointed muzzle. Chocolate brown fur covered the stoat's four-foot-tall body, with a creamier, lighter tan fur running from under her chin and down her neck to spread across her straining cleavage.

“Yes, Professor Morgan, of course."

The stoat's eyes shone as she stared at the crystal. The light reflected in Mina's eyes as her tail twitched a few times, then stilled.

“It's beautiful," she said.

The professor grinned and settled back on her coils. “That's a simple spell I loaded into the memory cube, too. The more complex you make it, the more intricate the crystalline structure becomes. Of course, you risk unstable structures, but with simple spells like this, you can put enough power into them that the crystalline structure is visible even without the use of a magical tool."

“Wow…"

Mina leaned further forward, her black nose inches from the shining crystal. Ribbons of energy coursed through the rock, creating light and shadow deep in the recesses of the mineral.

“So it's ready now?" she asked.

“As soon as the memory cube is broken, it releases the stored spell on the targets specified by the caster."

“And I have to make one of these to pass the test?"

Professor Morgan grinned and licked her lips with her forked tongue before replying.

“With your growing talent, I'm sure it won't be a problem. Besides, we had a learning experience last week, didn't we?"

Mina blinked and turned her head, blushing as she subconsciously pressed her paws down against the bulge, flattening it to the seat of her chair between her thighs. Yes, it had been accidental, but she managed to convince the professor to let her keep it. For now. Mina was used to the weight of the thing swinging over her shins and couldn't be happier with the effect it was having on her relationship with some of the other students.

“Anyways, as long as you're careful, you'll easily be able to manipulate a memory cube in a matter of days. If we pick a spell that you're very familiar with already, maybe something like a light-creation one, you'll be able to start tomorrow after you turn in your homework assignment from last week's lessons. I'm sure you were…"

Professor Morgan paused, lowered her eyes, and flicked out her tongue.

“... otherwise preoccupied."

Mina stared at her toes - or rather, where she used to be able to see her toes, now she got a noseful of her own overly generous cleavage. “I have that here," she said, mumbling into her chest. “I stayed up late to make sure it was done once I was able to… uh, focus."

The stoat stood up from her desk. The massive thickness between her legs tented outwards lewdly, but she ignored it for the moment as she focused on a shelf against the wall behind her. When she whirled around, her tail struck the pedestal that the bright blue memory cube floated above. Without the stand, the crystal smashed to the floor into a million pieces. A bolt of magical energy shot from the ground where it hit off the tiles and hit Mina square in the back of the shoulders.

“Ahhh!"

The stoat took a half step forward, knee bending, fists clenched as she froze in place. Morgan was already moving across the room when she realized the spell was taking effect more rapidly than she'd expected it to. Not that she expected it to be cast at all, but she couldn't put anything past her clumsy apprentice. Mina's shoulders stretched, bulging outwards, ripping through the seams of her button-up blouse, exposing the line where her brown fur met the tan fur. Enormous, powerful muscles popped against the stoat's sleek, shiny pelt as she twitched and curled her arms around, backside flexing and rippling, the motions spreading downwards with an accelerating pace.

Mina suddenly threw her head back, arms going wide, as her short, four-foot body swelled in size. Every bit of her, from the tip of her tail thwapping against the tiles to her round ears, grew bigger and bigger, though the increase of muscle mass around her belly and hips, down her arms and legs, outpaced the overall speed. Her already wide, stubby body grew even thicker and more solid as the tan fur covering her belly dimpled, revealing a six-pack, then an 8-pack, before her pelt squeezed in tight around every little fiber of power flooding the stoat's figure. Her breasts hid much of her stomach, of course, as the already oversized mammaries dropped so far out and down that the underswells came level with her hips. Despite how big and full and round the enormous teardrops were, the stoat's back and shoulders kept up the strength to easily cart them around.

The dress around Mina's hips ripped in two, splitting down the middle of the backside and front simultaneously as the powerful growth spurt continued. Her massive maleness was half of her own height to begin with, but now it fattened up significantly, until the head smooshed against the floor and turned at a ninety-degree angle. Inch after inch, foot after foot of half-hard, bright pink stoat-cock swelled from her sheath. She clutched her hands around her balls, moaning even louder as the pressure caused them to swell rounder, fatter, soft and full so that her outstretched fingers sunk down into them. The huge sac bounced off the floor before settling and flattening against the tiles, squeezed forward by her powerful, short legs.

The naga watching felt a thrill going up her spine as she watched her apprentice growing. The front of her elegant loincloth lifted, tenting on both sides. After another few seconds, the loincloth pulled backwards, sliding down between a pair of massive, pointed arousals jutting from a slit in the naga's lower belly. Her internal balls felt bluer than her own scales as she pulled the loincloth away and tossed it to the side. Her twin arousals were dark blue, almost black, and featured a pointed crown at the tip of each length. The long, throbbing poles also ridged, despite how stretched and taut they were, providing plenty of room for the wide veins powering her immense shafts - and extra pleasure for the recipient of the incredible thicknesses.

Mina's groans of pleasure grew louder and deeper as the stoat zoomed past six feet, then seven, then eight, doubling in height in just a minute or two as the spell worked its effect. Morgan was a powerful caster, so the results matched her ability, and Mina's thunderously low growls filled the room as much as her body did. Her head squeezed into the ceiling twelve feet above soon after, and she was forced to bend over as her massive, wide shoulders flexed into the concrete structure above. Between her legs, which spread around the bulk of her massive balls, her huge shaft flexed, half-hard, spearing outwards before rising up at the huge, dripping pink tip. Mina's plump lips spread, her breasts squeezing down around the base of her own maleness, as the huge stoat loomed over Morgan. Though the naga was still longer from nose to tail than the stoat was tall, the magician did not possess the improbably huge biceps, muscular abdomen, or domineering maleness that the stoat wielded.

“I guess today we'll be learning another lesson about the consequences of clumsiness," Morgan said, sighing as a huge paw wrapped around her back and sides, squeezing her arms in. “This is why you should always have a counterspell ready to defend yourself, Mina. Mmmph!"

The massive, muscular beast of a stoat didn't reply except to groan as she squeezed the naga's chest and body down into her massive length. Morgan stretched out, uncurling her coils before wrapping them around the enormous shaft, which was easily as thick around as she was around the middle. It flexed into the air, bouncing her as she massaged the head with her hands and squeezed her constricting lower body tighter. Mino dropped to her knees and humped forward, shoulders scraping off the ceiling as her breasts and balls fought for space between her powerful arms, which pressed forward into the floor for support. The enormous cock lurched upwards, rising higher and carrying Morgan with it, burying the naga in the stoat's deep cleavage for periods at a time.

Morgan shuddered as she felt the immense shaft flexing. It was so huge, and the smell was so good. For not the first time, Morgan considered herself lucky to have such a magic-susceptible apprentice. The naga's hood flexed as she squeezed and milked, urging a few more moans from the gasping stoat.

The naga's eyes went wide, though, when she felt Mina's paws return. Without warning, the huge and powerful stoat dragged the snake's coils away from the rock-hard arousal, and pulled Morgan's muzzle down towards the tip.

The snake-like lower half of the naga's body twisted and flicked in the air as she gasped.

“Mina, I know us snake types can open our jaws wide, but even we have limimmmmfffffss!"

Mina, however, wasn't in the mood to listen to another warning. Her biceps pushed out against her pelt, round and hard, matching her shoulders in strength and size, as she dragged the magic-user over her tip. Morgan's flexible snake-hide stretched, distending and showing the clear outline of the massive pink shaft around which she'd been wriggling moments before. Morgan's eyes closed and her lower half sagged as the huge stoat simple pulled her down tighter. The naga's heavy breasts squeezed between furry brown fingers as her long body slid every deeper down the massive stoat-stalk. It stretched her like a condom, shaping her long, tapering lower body into a tube around the thickness. Her nipples, hard and fat, wiggled madly forward and back as she swallowed uncontrollably, her whole body wiggling and spasming as the massive length filled her further.

The huge stoat paws grabbed at her, dragging her up and down, hard and fast, while at the same time thrusting awkwardly forward. Mina's huge breasts flattened above her even more massive balls as her cock extended, still growing fatter and longer until it was easily twice as thick as Morgan was supposed to be. The stoat grunted, flexing her arms and hips as she pumped hard, fast, her pleasure overwhelming her senses as the magic filled her massive new body. Her powerful backside clenched and she drove forward with all her power; the naga's entire body, from mouth to tail tip, squeezed and stretched around Mina's immense shaft. One paw shoved the naga's shoulders down, keeping her jaw stretched around the base of her cock, as the other stroked up and down from as far away as the growing hyper-stoat could reach. The naga's tail tip bulged outwards like a balloon hanging from a faucet as Mina's groans filled the room louder and louder, ringing in Morgan's ears.

The royal blue magician gurgled as waves of cum poured back out of her elongated body contouring so perfectly around the stoat's huge length. She closed her eyes, enjoying the stretching sensation, and flicked her long forked tongue out along the swollen urethra of the huge cock. The extra-strength spell that prevented these sorts of shenanigans from causing her any injury sure was going to come in handy in a few moments, she thought, judging from the way Mina's thrusts slammed into her more and more erratically. The snake's entire body stretched like a condom around the stoat's immense maleness as the overgrown student's moaning, trembling, thrusting body pummeled the shaft deep into Professor Morgan's bloating, balloon-like figure.

Professor Morgan would teach Mina the counterspell to stop the growth, of course. Just not until she was sure the stoat learned her lesson, even if it took all night and several refillings…
