Twilight Sparkle paced back and forth in her room in the new library castle. After the time that the Elements of Harmony were stolen, the time the Elements had to be given up, and the opportunity to have not only HER alicorn magic stolen but also Celestia's, Luna's, and Cadance's, she had to come up with a plan.

“There must be something I can do! The last few times we were LUCKY!” she muttered to herself, a hint of worry in her voice. “If any of the alicorns are threatened, we need a way to hide away our magic...” She gasped loudly, her horn lighting as she was struck with the idea, manifesting a light bulb over her head. Twilight rolled her eyes and levitated the bulb over to a closet. “I seriously need to stop doing that,” she commented, placing it on a large pile of about 50 bulbs in the closet.

Twilight walked over to her desk and unrolled a piece of parchment. She picked up a quill in her magic and quickly jotted down her idea. “The best place to hide something is in plain sight,” she read out as she wrote it on the piece of paper. Twilight nodded when she was done and rolled up her note, putting it into her saddlebag. “I know what I can try, but I'll need some books from the old castle!”

Wasting no time, Twilight galloped out to the abandoned castle in the Everfree Forest, and didn’t tell anypony she was leaving. The fewer ponies that knew about her idea, the better. Once she was able to figure out HOW to do it, she planned to pass on the info to the other alicorns.

“You know, this is exactly the thing Discord did that time he stole the Elements of Harmony. He hid them in plain sight! And nopony thought to look in the most obvious of places!”

The trip to the old castle was uneventful and the search for spellbooks fruitful. Twilight found a good number of books and flipped through them quickly, skimming for some sort of spell that could work.

“Come on! There has to be something in one of these books, there just HAS to!”

Frustrated after going through a fifth book and finding nothing, she picked it up with her magic and threw it across the room. The book slammed against the wall and knocked loose one of the stones. Curious, Twilight got up from her seat and walked over to examine it. She ran a hoof along the stone, jumping back in surprise when it sunk into the wall and a new door opened in front of her.

“A secret room?” she started, before she facehoofed. “Of course, Luna and Celestia hid all SORTS of traps and hidden rooms and-”

Twilight's words cut off and her wings sprung out in excitement. In the room was a single book sitting on a pedestal bathed in a bluish light. Twilight quickly flew over to the book and collected it, quickly scanning the title. She picked out a few choice words.

“Princess Luna.... transformation... spells! This is what I need!”

Wasting no time, Twilight returned back to the desk she had been using, carrying the book with her. She slipped the book into her saddlebag sitting next to the desk, and put the bag onto her back, then lit her horn. There was a brief flash of light followed by a pop sound and a puff of smoke, the castle now devoid of the purple pony. She teleported back to her room at the new castle, excited and anxious to get started.

Twilight quickly flipped through the book, searching for any spell she could try out. Finding one, she looked over it quickly, thinking she understood everything about it.

“This spell is exactly what I was looking for! This plan is genius, what could possibly go wrong?”

Before she cast the spell, though, she poked her head out her door and into the hallway, checking to make sure nopony was around. Satisfied that the castle was empty, she closed the door again.

“Ok, nopony's around, so I should be able to test this out without getting interrupted. Let's see, I have to stand like this... and-”

Twilight began to mumble out the directions from the book as she started to cast the spell. Her horn lit up bright and her wings flared out as she channeled her alicorn magic. Her eyes started to glow a bit as a bright bubble of magic slowly enveloped her body. The bubble grew brighter and brighter until there was a blinding flash of magic that filled the room and a loud bang that caused her room to shake.

Twilight shut her eyes as the magic worked, the exertion enough to cause her to pass out.


The train stopped at the station in Ponyville; a certain captain of the guard, Twilight's big brother Shining Armor, stepped off the train and stretched. He had not been able to travel like a regular pony in some time. He was technically royalty due to marrying a princess, but that didn't mean he had to enjoy every second of it. Shining Armor hadn't been able to see his LSBFF in some time, other than a situation that involved fighting off the latest evil trying to take over Equestria. Plus, Cadance had a tendency to nag him a lot, so he enjoyed getting away from her occasionally.

Shining Armor was a little disheartened as he walked through the town. According to a recent letter, Twilight's residence was destroyed in a large explosion, a casualty of his little sister's latest defense of Equestria. Fortunately, there was mention of a new place that was much fancier looking than a tree. He found the new residence easily, since it looked quite different from the other houses around town.

“Wow! When Twilly said she got a new place to live, I didn't expect it to be THIS fancy!”

Shining Armor slowly strolled into the new castle and was awestruck at the sight of the new library treehouse castle. As he explored, he paused and sighed.

“Argh... such a long trip, and not even a quickie before I left... Cadance really knows how to keep her stallion pleased...” Shining complained aloud as he started to ascend the stairs up to the private rooms. As he passed each door, he noticed each one had a mark that resembled each of the Element's cutie marks. That would make it easy to find Twilight's room.

As Shining Armor continued to search for Twilight's room, his sheath plumped up and the tip of his member pushed out a bit. “Erf... I might need to find a bathroom or something before find-” His words cut off when he found a door bearing Twilight's cutie mark. He raised a hoof to knock at the door but with his first knock, the door swung open. A few things seemed to be scattered about in a mess around the room. But then again, his sister wasn't the neatest of ponies. Especially if she was in the middle of studying something important.

“Twilly? You in here? Oh my Celestia! Don't tell me you've already started studying AGAIN!” he called out, looking around the messy room. He sighed and lit his horn, starting to pick up in the room. “I hope Twilight doesn't mind me tidying up while she's gone. I swear to Luna, she'd walk off the side of a cliff if she's engrossed in a book...”

It took some time, but eventually the messy room was straightened up. Papers were put back in place, an odd book was set on a desk as he walked.He caught only part of the title, something about Luna and spells.

Shining Armor was just about finished straightening up in Twilight’s room when he suddenly stopped in his tracks and glanced down; something brushed against his hoof. He wasn’t sure what it was, so he picked up the thing and looked it over, a wide grin growing on his face as his member pushed out even further from his sheath.

“I don't know why Twilight would have one of these toys, they're designed for stallions, unless...” he tapped his chin and laughed. “Unless it was a gag gift for her birthday from Pinkie Pie!” He glanced left and right before he dashed out of the room, leaving the door half closed. He quickly found a bathroom, went in, then closed and locked the door. “Gonna need some privacy for the next few minutes...”


Twilight groaned. Well, she didn't make any audible sound. She groaned basically in her own mind.

Ugh.... what happened... where am I? OH! The spell! DID THE SPELL WORK?

Twilight was unable to really look around, and she couldn't move. What she COULD see was she was in some sort of plastic or cellophane, but she wasn't sure which. Before she was able to fully register and make a detailed analysis of her current situation, she heard a loud voice.

“Twilly? You in here? Oh my Celestia! Don't tell me you've already started studying AGAIN!”

Shining Armor's here? Wait... SHINING ARMOR'S HERE!?

Twilight started to panic a bit. She still had an analysis of her spell to do and to test if she'd be recognized by anypony. Suddenly she realized that Shining Armor being here could BE that test. She anticipated a light bulb appearing again but oddly, nothing happened. In fact, she wasn't able to feel any connections to her magic at all.

If I can't feel any magic flowing through me, then my magic shouldn't be able to be detected! The experiment is a success!

Twilight's thoughts were interrupted though when she felt a hoof kick against her. She was able to see the white fur and recognized it as Shining Armor's leg. She saw a purple glow around her as whatever she had turned into was lifted up. Here was the true test!

“I don't know why Twilight would have one of these toys-”

Twilight stopped listening there. All she knew at that point was that she was some kind of toy and, more importantly, Shining Armor didn't recognize her. In her silent cheering and congratulating of herself, she hadn't even noticed they had left the room and had gone to one of the bathrooms, not until she heard the door bang shut and lock.

Wait... what? Where did Shining Armor take me? A bathroom? But why?”

Hundreds of questions ran through her mind, trying to figure out what was going on. At least this time, her thoughts weren't so focused that she didn't pay attention to what Shining was saying.

“Gonna need some privacy for the next few minutes...”

Privacy? Why would he need.. oh... my, no! Don't tell me he has to...

Out of everything on the list of things she never wanted to see, at the top of Twilight's list was watching Shining Armor taking a piss. And that's exactly what she was expecting, since they were in a bathroom.

After all, we ARE in a bathroom, what else would we do in here?

Before she could think on it any longer, she saw the aura shift and the plastic around her tear. She found herself falling a bit before she levitated in the air, hanging in front of Shining Armor's face, purple magic holding her still.


Shining Armor could feel his cock throbbing with need. If only he had some time with Cadance before having to leave... but that was the last thing on his mind at the moment. Slowly he tore open the packaging and pulled out the toy, dangling it in front of his face. He looked it over and laughed a little. The whole toy was quite long, yet for a stallion of his size, it was barely a medium. It was purple and pink in color, almost the same color as Twilight Sparkle herself. He poked a hoof at the entrance and felt a bit of give. It seemed like it was almost virginal.

“Of course the toy would be tight, it hadn't been opened yet,” Shining Armor said aloud.

He continued to examine the toy, noting what appeared to be wings as part of the decoration on the sides and what appeared to be Twilight's cutie mark. Shining Armor thought nothing of it though, just giving another laugh.

“This toy really does look like Twilly's colors, plus the wings and cutie mark... now I know this had to be a personalized gag gift!” He sighed a bit and shook his head. “I know she'll be upset if I use this, but I can always get Pinkie to make another one. Depending on how long it would take, I could get it before Twilight realized it was missing!”

With those words, he brought the toy to his lips. He gave the entrance a small kiss before his tongue snaked out. Despite it being a toy, he still took his time to pleasure the imaginary mare.

“Mmmm... Chrysalis... I've missed you so...” he moaned out, concentrating his licks on the toy's nubby clit. “What's that? You can be my any fantasy? Oh? My wife? Why would I want that?” he continued. “I've already got HER.” Shining Armor blushed bright as his cock throbbed and dripped out pre. “What's my greatest fantasy? Twilight. You can do that, right? You can?”

Shining Armor grinned, a lust filled look on his face. The toy was lubed up as best he could with his spit. Slowly he brought the toy down and pressed the entrance to his tip, feeling the toy stretch around it. It really was tight, forcing out a bit of his pre into the ribbed insides. “Oh Twilly, I hope you're ready...”


Twilight Sparkle watched in fascination as her brother looked over her. As far as she could tell, he had no idea it was really her. That definitely meant that her plan would work. Once she changed back, she would be able to go to the other princesses and tell them of the spell. But when she heard some of the things Shining Armor said, she got concerned.

“Of course the toy would be tight, it hadn't been opened yet.”

Twilight wasn't sure what Shining was meaning. What kind of toy is he talking about? Why is he- Her thoughts cut off when she felt a sharp spike in pleasure, a tongue licking at her... clit? If she would have been able to, she would have blushed then and there.

Ohhhh~ It's THAT kind of toy~ Wait... HE'S GONNA!

She barely paid attention to what Shining Armor was saying, attempting to use her magic to cancel the spell and return to normal. In her haste, she forgot that when she transformed, she could no longer feel magic coursing through her body. What brought her out of trying to change back was a movement. She was getting moved lower and lower. She watched as she passed by Shining Armor's lower belly and heading toward...

Oh Celestia no! Please let me change back! There must be something I can do!

No matter what Twilight tried, though, she was unable to change herself back. Of course, all those thoughts of changing back stopped when she felt her entrance stretched out by Shining Armor’s hard and throbbing cock; there was some kind of warm liquid dripping out as well. As the cock slid into her form, she could feel each throb, each heartbeat of the stallion's cock. She could feel each of the ridges as her tight passage rubbed gently, teasingly at the cock as it slid in. A few seconds of extreme pleasure turned to confusion. She felt the tip bump against the closed end of her form. Was she that small, or was he just that big? She was given no time to dwell on those thoughts; she felt the ridges rub again and a rather empty feeling inside of her as Shining Armor's member slid out of the toy almost all the way before feeling the thick cock ram back into her hard. Hard enough to bulge out the closed end of her new form.

This feels... so filling... so good... I'd even go so far as to say right, even though it's my brother! But this stretching each time he thrusts in feels odd. Still good, though.


Shining Armor wasted no time in sinking his hard cock into the toy. He grunted and looked down with a sigh and shook his head. “Guess the toy's a bit too small for me, looks like only about half will fit... still, it feels pretty good and tight.” More pre dripped out into the toy, making his thrusting easier. He slowly picked up the pace, getting as much in the toy as he could. A few hard thrusts and he looked down, seeing more of his cock in the toy and the end bulging out. “Well, it's probably not made well enough to go that deep at a fast pace but, Celestia does it feel good.”

He began to thrust faster as more and more pre dripped out. There was enough that a little was dripping out the open end of the toy. Despite the lubrication, the toy was still quite tight and pleasurable. Shining began to increase his pace even more, not paying attention to how quick or deep he was going.

“Oh Twilight, even though you’re so tight you can take my whole cock to the hilt. Have you wanted this as much as I have?” the stallion asked in a hushed moan, closing his eyes to visualize his little sister there, riding his cock. A sultry smile grew on his face as he rubbed the toy faster and faster. “Don’t worry, Twilly, I’m not planning to pull out. You’ll make a good mother for my foals~”

A few more thrusts; loud grunts and moans filled the small bathroom. “Getting close, Twilly, are you ready?” Another thrust, another grunt; his cocktip flared wide inside the toy and stretched it just to the limits. Shining Armor bit his lip, trying to stave off any loud sounds. His plan failed, though, and he threw his head back to let out a rather loud cry of pleasure.

“T-TWILIGHT!”


Twilight found it a little odd that she could taste the pre; it dribbled out to lube the musky cock as it slid in and out of her. It wasn't a bad taste, and definitely something she could get used to. But that musky taste started to mess with her mind a little.

T-tasty... so tasty... I'd love to get a stronger taste... I wonder what his cum will taste like?

Twilight tried to clear her mind of those thoughts, though. She had to figure out some way to change back.

N-no... I have to... to concentrate... I can't lose myself to these... these...

Her thoughts drifted back to the pleasure coursing through her body. As the stallion continued to pump his cock with her toy form, the pleasure inside of her cutting off her more rational thinking; she lost her mind to the pleasure.

Y-yes! Fill me up! Pump me full of your cum! Cum for me! Harder! Faster! I have to... no, I NEED to taste your cum! USE ME LIKE THE TOY I AM!

She could feel the cock pumping into her harder and faster, parts of her form bulging out. A few cracks began to form from the roughness. More pre dripped out, teasing the transformed mare.

NO! NO PRE! GIVE CUM! CUM CUM CUM!

She was barely aware of any other emotions or feelings at that point. She didn’t even feel when her brother’s cocktip flared out wide, making more and more cracks in the silicone toy. All she cared about was getting a taste of that creamy, delicious, musky cum. Shining Armor didn’t disappoint as his cock throbbed and released a torrent of cum into the toy. Twilight was able to finally get a taste of the cum and, had she been able to, she would have squealed in delight. That taste, though, was cut short when all the cum that was inside seemed to disappear, and part of her seemed to lose feeling. She didn’t even notice that loss of feeling; Twilight’s mind, unfortunately, had descended into a single thought, over and over again.

Cum! More cum! MORE MORE MORE!


Shining Armor slumped down on the toilet, panting hard after his pent up release. The unicorn stallion was covered in sweat and was breathing quite hard. Very slowly, he re-opened his eyes, and stared down at the toy on the end of his still spurting cock. A few more shots and he was spent; he sighed as he caught his breath.

“Well… that wasn’t unexpected…”

The toy was torn on one side all the way through to the inner chamber. Some cum still clung inside, but most had spilled out onto the bathroom floor. It barely hung on to the end of Shining Armor’s cock tip. Unceremoniously, he pulled the broken toy from his cock and looked at it, giving a shrug.

“A single shot toy… but still fun,” Shining Armor said with another sigh. He felt much better after finally having some time to himself. Slowly he lifted the broken pocket pussy in his magic and walked out. He glanced around to try and find a garbage can to discretely throw away the toy when he bumped into Spike, literally.

“Hey!” cried out the dragon. “Watch where you’re going or Princess Twilight will-”

Spike’s words cut off when he realized just who was standing there.

“Shining Armor! What an unexpected visit! … why do you smell like sweat and sex and shame?”

“Long story, Spike, but I need your help for two things, please,” stated Shining Armor. “First, have you seen my little sister? Twilly’ll be so surprised to see me!”

“I’m not sure where Twilight is, if she’s not in her room.”

“And secondly, in relation to your second question…”

Shining Armor held up the broken toy, a small bit of cum still dripping out.

“You might not be old enough yet for certain urges and I don’t have time to explain them, maybe Twilly will explain when your older. But can you maybe get rid of this for me? I’d rather not have Twilight find I’ve used one of her things like this.”

Spike gave a nod and took the toy in his clawed hand. He took a deep breath and blew out a gout of bright green dragon fire, engulfing the toy. Within seconds, the toy was an unrecognizable lump of silicon on the floor.


Twilight’s mind was a broken mess. Her toy body was ruined, it dripped out cum onto the floor. Once all the pleasure had passed, though, she was able to finally focus her mind as best she could. But with her form being broken, there were slight gaps in her memory.

O-Oh… that felt amazing! Now I need to… to… uh… I know I’m supposed to be a pony, not what I currently am. What am I? Wait, who is that stallion? He’s… yes, he’s my brother? I’m supposed to do something. Oh! That’s Spike! Spike will be able to remember for me! SPIKE!

Twilight Sparkle watched helplessly as she was lifted up in Shining Armor’s magic. She heard him speaking words, but she only understood about half. Something about Shining explaining something to her and Spike getting him something?

She found herself getting moved again, floating in Shining Armor’s aura toward the one… pony? dragon? She couldn’t remember what Spike was. But she was quickly approaching her assistant.

Shining Armor must have heard me calling out for Spike! Please help me remember what I’m supposed to do, Spike! Spike? Why aren’t you answering me? SPIKE!

Spike took a deep breath and blew out a gout of bright green dragon fire, engulfing the toy. Twilight could feel the heat as it engulfed her silicon body. As parts of the toy melted away, she felt her mind disappearing as well.

It’s so hot! Why isn’t… who is that white pony? I need to get help, something’s wrong!

Twilight could picture, at least for a brief moment, her friends. She couldn’t recall their names and eventually, forgot she had friends at all.

M-my friends will be able to help! Applejohn! Fluttershutter? R-Razor? Th-that’s not right… What are their names? Wait… whose names?

Memories of her adventures, her friends, family and mentors, all the ponies she had helped evaporated away. The only thing left, the last memory to go, was something was wrong and that something bad was happening. Her last thought was,

Somepony, anypony please help me. I don’t want t-


Spike looked at the rather small, purple, star shaped lump of silicon on the floor.

“All done, Shining Armor! I’m sure somepony’ll come clean that up.” Spike paused briefly, scratching his head. “Say, doesn’t that kinda look like Twilight’s cutie mark?”

Shining Armor looked down at the lump before he shrugged. “It kinda does, Spike. Weird.” He lit his horn and picked up what remained, unknown to him, of his sister. With a flick of his head, he sent the small lump hurtling right into the trash.

“There, that’s taken care of now. Let’s go see if we can find Twilight!”
