A Little Stone Adventure- Courtesy of Trixie

Twilight Sparkle was frozen, turned to stone by a cockatrice. She stood there with her hand half-raised, her eyes and mouth wide open with shock. All she'd been doing was a late-night errand for tea. Did that really warrant this?

She stood as a statue in the depths of the Everfree Forest. Her currently sightless eyes could just make out the path in the distance, but she’d lost it in the dark when a cloud went over the moon, and she'd tried to escape the hissing of the cockatrice. She stood in a clearing about a hundred meters from it. All was still. An owl came by to sit on her head for a few moments before it continued.

There was rustling in the bushes. Was it one of her friends, perhaps Fluttershy?

Instead, a navy blue unicorn stepped out of the bushes, dressed in a hoodie and a skirt. She was dirty and looked like she’d run through more than a few bushes. "Blasted cockatrices... just because I stumble into a nest or two doesn't mean--" She gasped, then peered into the dark, and her eyes widened. “Oh, sweet Celestia… Trixie's little friend was right for once!” She rushed forward to see her prize. Trixie cackled, “The great Twilight Sparkle, brought down by a cockatrice! Ha, ha, ha!”

Twilight did not respond, her frozen expression of shock did little to put Trixie off her gloating.

“Ha, ha, ha!” Trixie laughed again. She practically danced around Twilight, delightfully poking and prodding the statue that replaced flesh, “You can't do anything to me! Neener neener!”

After a moment, the silence was what put her off more than anything else.

Trixie hmphed. Then she grinned, “I can set you free, let it not be said the great and powerful Trixie is not merciful…!”

She conjured a spell, a ball of glittering blue flame, coalescing in and out of a sphere. The light seemed to make Twilight's face light up as it reflected off the glittering stone.

“You would be in my debt for sure! Freeing you from a lifetime of stone!”

Trixie laughed once again and drew her hand back. Again the light reflected, rising on Twilight's frozen face.

“...but why do we have to go right now?” Trixie murmured. She let the ball dissipate. “This is the perfect opportunity for an… experiment.” Trixie stepped back and pulled up her hoodie. Once free of it, she pulled off her shirt. She noted she was in full view of Twilight. “Don't watch me strip, you pervert,” She teased. When there was no response she sighed, “Very well. I suppose I will have to show you…”

Twilight had a good figure but rather modest breasts. She was hot in a ‘girl next door’ sort of way, quite standard, pretty attractive, but not what Trixie preferred. She was attractive, no doubt about it(not that Trixie particularly cared, no certainly not, no obsessive behavior at all!), and she may have been cute as hell(from an objective standpoint), and she might have made an adorable librarian(entirely objective), but she wasn't Trixie's fantasy. At least, not her favorite. Trixie grinned. She had the opportunity for a prank. A delightful little joke.

As Trixie pulled off her bra, her breasts bounced out. They weren't enormous, but they were perky enough to attract attention. She grinned at that. She had a well-toned ass and a skinny figure that nevertheless drew eyes from mares and stallions alike. Not that she liked stallions, gross. Trixie shimmied out of her skirt, and smacked her backside very gently, “How’s that strip tease, Twilight?”

Of course, the unicorn didn't respond.

Trixie made a magic gesture, and a smock appeared from a small portal, along with a large fabric bag and a set of trowels. She pulled on the smock, hiding her body from view. She looked in the bag. She swore and threw it back into the portal. She drew out a different one, and this time smirked. “What do you know about cement, Twilight?”

Twilight probably knew a lot but wasn't aware enough to respond.

Trixie stepped closer. She cast a spell. The stone that formed Twilight's clothing disappeared. It was not part of Twilight's body after all. Trixie took those fragments and mercilessly mashed them into a paste, mixing them in with her other cement. She wasn't going to need them, and Trixie needed more plaster for what she would do.

Trixie admired her enemy's body. “So sweet. Cute. But you know what? Trixie’s rival shouldn't be so weak.” She ran her hand up Twilight's sides, “These are so…simple. So not muscular.” She felt up her breasts, “Eh.“ She looked at Twilight's surprised frozen expression, “Now…to work.”

Trixie slapped Twilight's snatch with plaster. She grinned and picked up more with a trowel. She quickly turned Twilight's vagina into a mound of stone and gooey sticky plaster. Quickly, once the material was high enough, she began to make circular motions around it. Trixie grinned as she worked, moving her fingers with dexterity. Rapidly she built it up, creating a long cylinder. As she did so, she used her magic for extra hands and shaped the end into a bell shape. She stretched it longer and longer, reaching nearly a foot. Trixie grinned. “A foot-long morning boner, how appropriate,” She said. A truly massive erection took shape, a long veiny member that was just barely proportional to Twilight's body. It was big enough to satisfy most mares, Trixie thought, and then smirked, “And of course…” She added some hefty testicles. They seemed comically oversized, bulging, and ready to burst.

Trixie applied a spell. A purple circle appeared a centimeter from the plaster and mortar and ran up and down it. She felt the heat from where she was standing. Within seconds, the loose material had hardened to stone. Permanently part of Twilight. Her snatch was gone.

Trixie looked her up and down. “Well, we can't have this be disproportionate, now can we?” She looked at her bucket of plaster, “And we still have so much to work with…”

Trixie put the plaster in her hands and slapped it onto Twilight's chest. Their form and nipples disappeared under the goo, and it began to drip. Trixie summoned a spell, which caught the dripping material in a pair of half circles. The purple energy coalesced and swiveled up like a door, forming cups over Twilight's slick stone breasts. Trixie narrowed her gaze. Two tiny holes appeared in the top of each magic cup. She summoned a pair of balls of mortar and fed them into the cups. “Hm…” Each magic cup was crammed full of the material, fit to bursting. Then Trixie smirked and made them a little bigger. Once filled again, she made them even bigger. And bigger. Each time they filled to the bursting with mortar. Trixie reached out a hand, comparing her fist to the bulging purple cups. Then, finally, she smirked once again. The holes opened up, and two pinpricks, one on each cup, extended out. Trixie summoned the heat circle once again.

When it was done, Trixie reached forward, “Oh, my goodness gracious…dear Twilight, what are you doing without a bra?”

Twilight's breasts had been smothered under mortar. In their place were a pair of enormous teardrop-shaped stone tits, each bigger than Trixie’s fist, and utterly defiant of gravity, with quite distinct erect nipples. They were perky, and huge, and Trixie purred as she felt them up. “Won't these be delightful for all the stallions around?”

She looked down. Twilight's bust and penis had been improved and added upon, what about the rest of her? Trixie stepped around her “sculpture”, considering it. The mare's flanks weren't exactly complimentary, Trixie had to say. Twilight was quite content with them, but her thoughts on the matter sailed when the cockatrice got her.

Trixie sidled up behind Twilight. She breathed in the frozen mare's ear, and moved her hands over her hips, along her waist, slipping to the front of her stomach. She reached down and felt the hilt of Twilight's new toy. Trixie frowned. She ran her hands along Twilight's waist again, and as she did so, slivers of stone began to shave themselves off. The mass was sent down lower, adding to her hips. She felt Twilight's flesh remodeling itself for her hands, her end finger brushing against the rising hips. Trixie’s frown grew into a smile. When she was done, her hands could slide quite smoothly from feeling Twilight’s ass to her cock.

Trixie stepped back, her smile fading. Twilight had developed some nice curves, but she felt Twilight's butt. “Well, that's going to have to change.”

Immediately she pasted it with mortar. She formed a similar pair of cups to Twilight's boobs, but only slightly. This mold was taller, affecting her entire posterior. Trixie poured in the cement and immediately applied magical pressure. Behind the transparent material, she could see the gray goop plaster itself across the bottom of Twilight's butt to her lower back. Trixie frowned then another purple line climbed up Twilight's spine. She nodded, then went to work. She poured on the cement, and added layers and layers to Twilight's butt, putting on years and years of meat and vegetables, and particularly sweets. As the cement and plaster spread, Trixie pushed it beyond her ass, affecting her hips, and flowing up her spinal magic casing.

Twilight's ass grew in seconds. From a distinctive feature about her to rivaling her new chest in terms of size. It was smooth and voluminous. Trixie reached out and massaged it, spreading it around slightly. The mass smoothed into a more muscular bubble butt, while her hips seemed to draw out. “You'll need that spinal stuff to stand…” Trixie murmured. She took a step back.

Twilight had previously had a generous figure, but more of a sexy librarian look. Now, it was stunning. She was as top and bottom-heavy as Celestia was. She had a gorgeous hourglass silhouette, packed on with muscle and meat that Trixie just wanted to take a bite out of.

But Trixie had to control herself, she had more to do. Trixie chiseled off Twilight's hair completely, leaving her smooth. “I could leave you like that, bald, with no explanation,” Trixie said, “Wouldn't that be fitting?” She looked into Twilight's frozen, stone eyes, “But I'm merciful. Heck, I'm going to give you a gift.”

Trixie picked up a ball of plaster. She plopped it onto Twilight's head. The plop splattered some goop down onto her eyes.

“Oops,” Trixie said. She cast a spell, and seemingly perfect eyes were chiseled out again. Trixie smirked. “Starting that earlier, I suppose.”

She snapped her fingers. Some cement scraps appeared and formed into a wire frame over Twilight's face. They solidified into a transparent barrier over her eyes. “I think you needed that even before I got here,” Trixie murmured.

The unicorn magician went back to work. She straightened the goop, and a mold went over Twilight's entire head, with a long curved cylinder behind her.

Trixie restored the mass of Twilight's hair in seconds, though she cut her bangs a bit. She furrowed her brow in concentration and used her hands for additional supportive gestures. Twilight's hair was as unruly as ever, but smoother, like it had been styled. More significantly, Trixie noted with satisfaction, it had been formed into a perfect ponytail, with a stone scrunchy and everything. “Trixie always liked her partners to put their hair up,” She said, leaning in toward Twilight teasingly.

Trixie took a step back. The frozen mare had been completely altered. She was naked. None of her clothes survived the raw material process. Twilight's breasts were enormous, the size of cantaloupes at least, if not larger. Her body had been transformed into an hourglass shape, a curvy and sexy body that made Trixie drool. She wiped her mouth as she admired her handiwork. “Dang, Trixie is good…”

Instead of a nerdy librarian, Trixie left a naked Amazonian nerd. She was done altering her. For now. Trixie snapped her fingers, and dove into the bushes.

The additional stone turned into flesh, adding mass as if she had had it for years. The plaster marks vanished, replaced with a pure purple body. Her breasts, once released, bobbled and jiggled like they were made of jello. Twilight collapsed to the ground, falling onto her new bubble butt with less pain than expected. And then her cock came down, fully erect and at the ready.

A naked Twilight Sparkle went from standing up to falling to the ground. She let out several confused sounds of pleasure, pain, and shock. She yelped and moaned, her back arching as she processed what was happening. Her whole body was filled with a stinging pins and needles sensation. What's happening? I–

Her center of gravity had shifted dramatically. Her nipples hit the ground and she let out a scream. Twilight rolled onto her back, looked down, and screamed again.

There, on her chest, were some of the biggest boobs she'd ever seen. They were enormous, massive handfuls. She cupped them and felt herself nearly cum from shock. They were tremendously sensitive. She rubbed them and they nearly made her orgasm. “What's going on?” She mumbled. Then she noticed an odd motion on her lower body.

She sat up. Her whole body seemed to shift and tremble. She gasped. Her body had been transformed. She squirmed, “What the fuck?!” From what she could see past her boobs, her entire body had been reconfigured, her proportions altered. Her hips were spread out, her waist was drawn in, her butt felt like a cushion: and there, between her legs, was a footlong fully erect cock.

Twilight's eyes were the size of dinner plates. She grabbed it and almost shouted. She let out a yelp. It was real! Real as her leg or her head! She felt her lower body. It was an exaggerated hourglass, as far as she could tell by touch. Her snatch was gone, replaced by this… thing.

She found a pair of glasses on her nose. When she removed them, things further away were blurry. “What the…? Whoa, that’s way better, I guess…” As she found later, this was left unchanged. She just never knew she was nearsighted.

Twilight felt her sides, felt her expanded and transformed flanks. She gasped in shock at her increased sensitivity. “Wh… why do I have a dick? When did I get glasses?” She looked down at herself, “Why am I naked?” She felt her hair, “And why do I have a ponytail?”

she heard a slithering sound and a hiss. she took off running. her center of gravity was shifted. She didn't run right. She felt her whole frame jiggling.

Trixie loved watching her ass shake from side to side. Then she heard a hissing. Then another. And another. “Oh…shit,” she mumbled. “I think I’ve made them angry!”

Twilight couldn't go to Zecora’s like this. Her cock softened but was still enormous. She stopped, leaned against a tree, and felt her breasts. How did this happen? How did she get so… hot? The word sprang into her mind and she shook her head. She remembered another mare from some time ago, with glasses, and a great figure, but she didn't want to be her… did she? She often wondered if she wanted to be her or on top of her.

Twilight realized her hands were rubbing up and down her new sex organ as she thought. She shook her head. She was in danger! Someone had taken her and changed her without her consent! She had to get to safety! And find clothes!

She heard that hissing again. It seemed the creatures of the night were disturbed by something.

Fluttershy! She thought. Fluttershy is out tonight! She can help me! She sprinted off into the woods.

Trixie followed as stealthily as she could. Her joke was going quite well Hm, how am I gonna switch her back? Trixie thought. She realized sometimes she should think ahead.
