“Twilight? Are you here?” Sunset called as she entered the, soon to be college bound, friend’s home. Their graduation had been just last week in fact. Sunset could barely believe so much time had already passed. Here they were, eighteen and getting ready for college. Of course both her and Twilight were set up to be roomies in their new dorm. Sunset couldn’t think of a better one to have. She also should probably help Twilight with packing. If she wasn’t mistaken, her parents had to go on a trip to help some relatives? Which meant if Sunset didn't watch her, Twilight was bound to forget to eat. There was only so much even Spike could get her to do when she was tied up with whatever experiment she had texted her about this morning.
Well she could ask when she found her. “Sci-Twi?” Twilight hated that nickname, so it usually got a response from her. After several seconds of silence however, it seemed she either didn’t catch it, or just wasn’t here.
“Spike?” She tried still making her way through the house.
“We’re in here!” Spike called from the back. Twilight’s voice quickly followed it.
“Spike! I told you not to move!”
“But Sunset was calling!” There was a pause and Sunset could hear her fumbling with something, her tone one of puzzlement.
“She is? I don’t see a missed call on my phone…”
“That’s because I’m calling you in real-time.” Sunset teased as she walked through the door to the garage, which in reality had become Twilight’s ‘lab’ as she had completely taken it over with all sorts of little machines and beakers. It looked like one of those mad scientist labs right out of a movie.
“Oh sorry, I’ve been really engrossed in this experiment,” Twilight replied, removing the goggles she had been wearing. Sunset smirked at Twilight’s outfit. Back in high school when they’d first become friends, Twi would be all decked out in a full lab coat buttoned up and everything when she worked. Now, while she still had some sort of protective jacket on, it was left open, showing off her real outfit which consisted of a plain black skirt that went down to her knees, and a purple shirt that while it covered her, it wasn’t enough to completely hide just how developed her chest had become. In short she looked like a science babe. Sunset bet Timber Spruce had a picture of her like this in his wallet…
Then there was Spike. He hadn’t grown too much bigger, but he was far from a puppy anymore. His collar being brand new as he’d outgrown the last one. He was sitting on a pillow on the ground looking bored. Still, he was being a loyal dog and waiting for her to finish up whatever this was.
“So what else is new?” Sunset joked, taking a look at the odd setup before her. It consisted of a machine with all sorts of vacuum tubes and lights, with wires connecting from it, clipped to Twilight’s geode stone around her neck, and to the collar around Spike’s neck. Or more precisely something on the collar that looked like a scale?
“So what's up?”
“I need you to observe this experiment and take in anything you see that might be of use to said experiment,” Twilight replied as she looked over a clipboard. Then in a much quieter voice, she added: “And to help us if something goes wrong…”
“Wait what can go wrong?” Spike asked nervously, but Twilight ignored him.
Sunset shrugged. “Okay and just what is this experiment?”
“Nothing too complicated. You know how the geode’s magic appears linked to us directly? Well I’m trying to see if I can give Spike a faux geode as it were, but with real magical properties.”
“I see…” Sunset had to admit it was an interesting idea. However: “Any reason why? And what exactly is that around Spike’s neck?”
“A dragonscale.” Twilight beamed looking up. “It’s from his counterpart in Equestria. I figure since they’re basically the same in biology, it should be the easiest to not only infuse it with magic, but link it to his essence in the process.”
“It would be cool to be able to breathe fire or something.” Spike said, wagging his tail. “Plus Twilight says she’s going to buy me those GOOD biscuits if I’m a trooper.”
Well that answered why Spike was on board, but there still seemed to be something off about all this.
“Okay but you didn’t answer-”
“Alright everyone! Places!” Twilight yelled rushing over to the machine where it of course had a lever for her to pull. “And three, two, one!”
Before Sunset had a chance to get her wits about her, the machine fired up. Though Sunset had no idea what components of the machine did what, it seemed to be running correctly. Though why did it have a plasma ball on top of it?
After a few seconds the machine began to print out a chart feed that Twilight quickly began to look over. Sunset smiled. Why not just have a digital print out?
“Hmm no good, I don’t think a connection is being made between my geode and his scale.” Twilight bit her lip as she glanced at Spike who was too distracted by the plasma ball to care about much else.
Now for the hard part. Twilight thought as she began to focus on drawing energy from her geode. She could feel it floating. As she worked the machine kicked into high gear. Spike remained in awe when a small spark of magic ignited around his scale.
“Huh? Hey Twi, it's doing something!”
Twilight smiled wide at hearing that, but Sunset swore she almost looked… relieved?
“That’s great Spike!” Twilight now had her focus on the scale as she continued to draw power from her geode. “Let me know if you feel any magical connection like you did when you gained the ability to talk! In the meantime I’ll try to draw out even more magic!”
The machine immediately began to spark and fizzle.
“Uh Twilight?” Sunset said, taking a few steps back, “I think that’s enough.”
“No, I have to get more. I need to make the connection!”
The machine began to whine as the plasma ball on top became a blur of energy inside it. As Sunset watched it began to fire off tendrils of energy directly into the machine itself.
“No, I really think that’s enough!”
“I-I agree Twi!” Spike cried looking at the machine. “We’re going to blow it up or something!”
“B-but the scale! We have to infuse the scale!” Twilight cried. To Sunset it sounded like she was desperate. Why was this such a big deal?
“Forget it Twi!” Spike yelled over the now smoking and deafening machine. He began to push his paws against the collar. “I’m taking this stupid thing off!”
“Wait, don't! You nee-” Twilight cried rushing over to stop him. Spike had just gotten the collar up to his nose when Twilight grabbed it. The moment she did there was a huge flash of light and both went flying, breaking the connection from the machine and causing it to shut off.
“Twilight!? Twilight are you okay!?” Sunset screamed over the ringing in her ears, She rushed over to where she’d seen the girl land. Thankfully Twilight had landed in a box full of old clothing that looked like it was to be donated. She looked dazed but okay.
“Twilight speak to me!” Sunset cried helping the girl up. Twilight looked at her confused.
“Huh? Who’s there? Why is everything so blurry?”
“Your glasses fell off. Now get up, we need to make sure Spike is okay. Spike? Where are you!?”
Twilight’s confusion only grew. “What? But I’m right here, and I don’t wear glasses. Why do I sound and feel so funny?”
“Spike? Sunset?” Spike’s voice called as the canine crawled his way out of a pile of boxes. Unlike Twilight, he didn’t seem to have the same graceful landing, but thankfully looked unharmed.
“Everyone okay?” He asked wobbling on his paws before stopping to look around with his own air of confusion. “Wha!? Why is everything so big!? Wait! My voice!” With a glance down he began to panic.
“Oh no! No no no! This isn’t right! This wasn’t supposed to happen!”
“Wait, what wasn’t supposed to happen!?” Sunset cried, getting more worried by the second “What’s going on? Spike what’s wrong?”
Spike looked up at her, panic in his eyes. “That’s what’s wrong! I’m not Spike!”
Sunset replied the only way she could. “...what?”
“Oh there we go!” Twilight exclaimed putting on her glasses. “Whoa! How am I so tall? W-whoa!” Trying to take a step, she nearly toppled over, only for Sunset to have to grab and steady her.
“Man I was blind as a bat without these on! Wait how did I lift them with my paws-” She rattled on before stopping to stare in equal shock at “Spike” on the floor.
“Huh?! How am I down there!?”
Sunset couldn’t believe what she was hearing, by the way they were talking that couldn’t really mean…
“S-Spike?” Sunset asked slowly, staring at the newly eighteen year old girl she was currently helping stand.
“Y-Yeah it’s me.” She squeaked before looking down at herself dumbstruck.
“Am I… Twilight?”
* * *
“Okay so the general idea is that by trying to push some of your magic into Spike via your machine, touching him caused your brain to swap with his…” Sunset rubbed her head as she spoke, staring at the two across from her. Twilight in Spike’s body was sitting on one end of a couch looking uncomfortable and trying to stop herself, himself? From scratching his ear. While Spike in Twilight’s body was on the other end looking at this thing and that with utter amazement. Currently she is playing with a puzzle cube.
“So this thing really does have different colored sides!” She cried moving the blocks this way and that. “So cool!”
“Y-Yes.” Twilight replied, wincing at his new voice. “If I had to theorize, the geode tried to put my essence into Spike’s body, but since he was already in there, it simply moved him to my now unoccupied body.”
“Causing you two to basically swap bodies.” Sunset finished pinching her nose. “How do we fix it?”
“Well it should work the same way we swapped in the first place.” Twilight replied as her paw finally began to scratch at his ear. “Spike just needs to focus and draw magic from my geode while we’re hooked up to the machine and then touch me. In theory the same thing should happen.” He scratched faster, making little grunts of satisfaction as he did.
“Yeah there’s just one problem with that.” Spike chimed in, grasping the geode around her neck. “I don’t feel any sort of magic from this, and I have no idea how to draw power from it.”
Putting down the puzzle, she turned to smirk at her owner in her body.
“Also do you know what you’re doing right now?”
Twilight paused at that suddenly aware of her actions. Quickly placing his paw back, he fake coughed. “Y-Yes um, perhaps there are some traits of each other still in our bodies? This would be rather fascinating to study if it weren’t imperative we get our bodies back in order.”
“Hey take your time, having thumbs is awesome!” Spike cried picking up and setting down various things with her hands. Sunset rolled her eyes. She was having way too much fun with this. Should she even be labeling Spike as a she? He may be in Twilight’s body, but he was a boy dog.
“Okay before we get off topic.” Sunset interjected. “Let’s back up to the geode thing. Spike you say you can’t feel it’s magic?”
“Nope, not a thing.” To demonstrate, she grasped it and closed her eyes in concentration, but no matter how much she sat there, not even a tiny spark of magic manifested. After a few minutes she let go with a gasp.
“I mean I don’t know how Twilight connects to the thing in the first place, but nothing I can think of to make it do anything.”
“Twilight this is bad. If she can’t draw out the magic, how are you going to swap back?” Sunset grit her teeth, but couldn’t hold it back any longer, “and I know this shouldn’t matter, but is calling Spike she correct, or should I say him?”
“Pronouns are the least of our worries right now Sunset!” Twilight growled in frustration as she stared at her tail. Every fiber of her being was telling her to chase it. “If we can’t get my geode to work, t-then I’m going to be stuck as a dog!”
“Oh no how horrible.” Came the flat reply.
“I-I didn’t mean it like that!” Twilight quickly added. “It’s just I can’t live your life for you Spike!”
“Right, and I doubt I could live yours. Even if being able to see in color is so freaking cool!” Spike squealed just like Twilight would when she got excited.
“Well that sounded rather girly.” Sunset added slowly watching them both. “Twilight. I don’t think it was a clean swap, you seem to have traits of each other still in your bodies. Hence why I’m still wondering what pronouns to use.”
“Sunset!” Twilight cried, before he seemed to actually mull it over. “A-Actually that may be a bigger issue than I thought. If I think about it. I feel male? I’m not sure how to describe it, but if I was to refer to myself as he or her, the masculine identifier is the one that leaps out to me.”
“C-come to think of it, I do think ‘girl’ when I think of myself.” Spike added, looking at her body. “T-That’s really weird. Okay, maybe there is something to swapping back soon. How do I use this thing?”
“That’s just it, I’m not sure how to teach you!” Twilight cried as he paced on the sofa, still occasionally scratching at his ear. “When I got it, I just felt connected. I didn’t have to do anything special.”
“It was the same with mine.” Sunset added. “I mean we were using the powers before we even got our geodes. It’s like it linked to our very…” Her eyes widened.
“Wait! I’ve got an idea! Twilight! I mean Spike, give me the geode!”
The girl looked stunned. “Uh sure here ya go.”
“When trying to solve a problem, always try the simplest solution first!” She cried before placing the thing around Twilight’s new canine neck. “Now try to use the magic!”
“R-right, it connected to our very essence, and if mine is in this body then-” The geode didn’t activate, but it did spark.
“It’s responding! Keep trying!” Sunset cried. Twilight nodded and closed his eyes.
“It’s like… it’s muddy but I can sense it. If I just… focus…” A few more sparks and the geode jerked before glowing its normal purple color.
“Success!” Twilight cried lifting up the puzzle cube from its spot on the table. Smiling, he proceeded to complete it as it floated in the air. Sunset giggled.
“Alright showoff, now let’s get you back in the lab and fix this.”
“R-right, the sooner the better.” Twilight replied, his voice strained. “No offense Spike, but ever since I ended up in your body, I’ve felt this… growing discomfort.”
“Is your essence not taking to his body?” Sunset asked concerned. “What about you Spike? You feel alright?”
Her response was a slight blush. That wasn’t good.
“Oh geez, you’re getting red! What’s wrong?”
The blush grew. “Uh no, I actually feel fine, it’s just… I think I know what’s wrong with Twilight.”
Both turned their heads toward her. “Oh?”
“Y-Yeah uh… Twilight. There was another reason I was having trouble sitting still for the experiment…”
Twilight raised the equivalent of an eyebrow on dogs. “And that is?”
Spike didn’t seem to want to answer, but whispered. “I-I had to pee…”
Twilight’s face froze. “What?”
Spike spoke louder.
“T-that sensation is you have to pee. My, and now your bladder was getting full…”
The moment he heard that it was like two puzzle pieces fell into place in Twilight’s mind. With a whimper she began to dance a bit.
“I-I was wondering why it felt like building pressure! I-I thought it was just nerves but now that you said that… Gah! I’m gonna lose control!”
“Q-Quick! Go outside!” Spike cried pointing toward the door. Twilight’s eyes widened.
“What!? I’m not going to go in the bushes like some-” Her voice caught.
“Like some dog? You are a dog right now Twilight, and I don’t think you have time to learn how to use a toilet while that size, unless you want me or Sunset to hold you over it!”
“NO!” Twilight cried clearly mortified. “I-I’ll… ugh! We’re fixing ourselves the moment I’m back in here!” He screamed before rushing out the door.
With a sigh, Spike settled back down on the couch while Sunset tried to hold in her laughter. She was totally going to have to use this against Twilight sometime in the future.
“So, ready to go back to being a dog?” Sunset asked after a few minutes. Despite the possible dangers. She had to admit it must be neat being in another body.
“Not really.” Spike replied, examining her hands. “There’s so much I could do in a body like this, it’s a shame I only get a few minutes. Uh, not that I’m not going to swap back mind you. I could never do that to Twilight.”
Sunset nodded. “I know you wouldn’t and hey, maybe we can find a safe way to do this? I mean I might swap with you. Being a dog could be fun.”
“Maybe.” Spike replied, trying not to touch herself in odd yet rather alluring places. Twilight would freak. “Though maybe we can get a guy to swap with me. Being a girl is kinda weird.”
“I bet, not only are you human now, but the opposite sex. Must be quite the shock.”
“Yeah, but I really am enjoying the human part.” Spike replied, wiggling his fingers. Sunset had a feeling she was wiggling her toes as well. “Someday, I’d love to have more time as one.”
“EEEEEEEEEK!” They heard Twilight scream. Sunset was out the door in a flash, Spike doing her best to catch up. She still wasn’t used to having human legs, and wasn’t able to adjust quickly enough, though at least she wasn’t falling over.
“Twilight!? Twilight what’s wrong!?” Sunset cried searching for her dogified friend. Said friend came rushing up with another look of panic.
“It’s gone! That stupid bird took it!”
“What? What’s gone? What bird!?” Sunset screamed back feeling a growing sense of dread.
“I-I didn’t want to get my geode w-wet.” Twilight said quickly with a blush. “So I took it off to, you know, when this crow just swooped down and grabbed it! Then it flew off that way!”
“What? Where?!” Spike cried wobbling over. She didn’t mean more time as Twilight right now! “Q-Quick! Maybe we can catch it?”
“We have to catch it!” Twilight screamed his body ready to rush off. “If we don’t, not only are we stuck like this, but someone else might get that geode and any number of bad things can happen!”
“Right, let’s go!” Spike cried trying to rush in the direction pointed, until Sunset stopped her.
“Oh no you don’t, you can barely stand in that body, let alone chase a crow. Twilight has experience walking on all fours when she was a pony that one time, so she’ll be fine.”
“R-right!” Twilight agreed. “I-I don’t like it, but Spike you stay here and don’t do anything stupid with my body! Sunset and I will contact Fluttershy, find the crow and get the geode back!”
Spike stood there for a moment before slumping her shoulders. They were right, it’d take her far too long to get comfortable enough with this body to really help.
“F-Fine, just hurry back okay?”
The two nodded and rushed off, leaving the new human girl to stumble back into the house.
* * *
Spike had hoped they’d be back in just a few minutes, but as a half hour went by, it became clear that this was probably going to take a while. Which means she had some time to kill.
She thought about just putting on a movie and marveling at the expanded color palette she was now privy to, when a better idea snuck into her brain. Could she do that? Well she did have the right body for it. Twilight might get a little mad at her, but how could she pass this up? This was the dream!
Making her way slowly into Twilight’s bedroom, she headed straight to the desk where she knew her prize lay inside, just waiting for her to grab it. Reaching out nervously she slowly opened its drawer. Her breath caught. There it was in all its glory.
It was beautiful. Just sitting there, all shiny and black. In the past if Twilight had seen him dare to put his mouth on it, there’d be hell. As Spike he’d be in so much trouble for even thinking of touching it.
But she wasn’t Spike right now. She was Twilight, or at least in her body, and he knew for a fact this body could handle it.
“I’ve wanted this for so, so long…”
Trying not to lose her nerve. She slowly reached out and picked it up. It was cool to the touch, kept at the perfect temperature thanks to the cooled house.
Rapidly making her way to the kitchen, she got herself ready. Sitting in a chair at the table, she took one last look at it, trying to work up her nerve.
“You’re fine. This is Twilight’s body. You know it won’t hurt.”
Making a silent wish, she finally ripped off the wrapping and took a huge bite.
“O-Oh dear stars and skies!” Spike cried out as the taste of the chocolate flowed over her tongue. This! This was what heaven was! This texture! This taste! The sweetness! She’d always been jealous of Twilight being able to have it, but he couldn’t.
“It’s not fair!” She cried, actual tears flowing. “Why are humans able to have this but dogs can’t! Why!?”
Twilight wouldn’t mind if she had just a few more bites right?
* * *
“So wait, that's really Twilight in there?” Fluttershy asked as she bent down to look ‘Spike’ in the eyes. Said dog could only blush.
“Y-Yeah it’s me.” He replied, trying not to make eye contact. Fluttershy really did have some strange connection to animals, as he could feel something inside him drawn to her even now. However, given he was a human girl not one hour ago, her newly male brain was having a short circuit. Like what if Fluttershy was a girl dog…
He shook his head trying to dislodge that thought. This was getting way too weird, they needed to find that geode and fast!
“Oh my are you okay?” Fluttershy cried picking him up. Naturally this didn’t help the strange sensations his body was having.
“It must be so strange being in Spike’s body…” Flutters seemed to be trying to hold herself back, but much like Sunset earlier, couldn’t manage it.
“So how’s it like being a dog? How weird is it seeing in their restricted colors? Do you like being petted?” Before he could answer any of those, Fluttershy proceeded to actually do that last one, giving a quick scritch behind his ear. His body involuntarily began to pant and wag its tail.
This felt so good! Why was it so good!?
“Ahem.” Sunset said, giving a fake cough. Fluttershy blushed.
“O-Oh right sorry, it’s just… wow this is so cool!” Spike, or rather Twilight just stared at her.
“Right, weird for you, but kinda cool?” She put him down.
“I-It might be if I wasn’t afraid of being trapped in this body!” Twilight cried trying to clear her head. “Now we really need your help finding that crow!”
“Yes of course!” Fluttershy nodded, trying to compose herself. She wouldn’t mind seeing if she could swap with an animal after this was all done. Think of all she’d learn!
“I can talk to the birds and see if they can track down the crow that took your geode. It might take a couple of hours though…”
“Better than it not happening at all.” Sunset said.
“Agreed, we just need to find it so I can swap us back and figure out what went wrong so next time the experiment works properly!”
“Wait, you mean to try again?” Sunset asked, furrowing her brow. After how dangerous it turned out to be?
“I have to! It’s very important I get this to work!”
“Twilight, it’d be cool if Spike had magic but-”
“No time!” Twilight cried prancing in place. “Fluttershy! Where do we go for you to talk with your bird friends?”
“Oh uh, the park would be best I guess-”
“Then let’s go!” Twilight yelled as he began to run toward said park. Both girls blinked in surprise before rushing after him. Fluttershy spoke first.
“Um, is it just me or does Twilight seem worried about something other than swapping back?”
“I’m getting the same feeling…” Sunset didn’t know what was going on, but something was bugging Twilight, and she just hoped he’d talk to them instead of forcing Sunset to use her own geode.
* * *
“So… I’ve eaten enough chocolate I guess…” Spike groaned as he washed the stains off his hands. Seven bars, several kiss bites, and even a few sodas to wash it all down. Yeah Twilight was going to notice something. Maybe she could convince her she’d forgotten to stock up? Well worth a shot, but at any rate, that was a future Spike problem.
Right now she had to deal with these chocolate stains. This likely meant she’d have to change clothing. Change Twilight’s clothing that she was wearing.
She stared at the dress with Twilight’s clothes.. All her clothes. That included her panties and bras. As a dog they were just cloth, but as a human girl. She knew what they were meant for. Somehow that made them something sacred. Like she shouldn’t dare touch them.
Okay come on now. She scolded herself, reaching for a drawer. Stop being silly and just grab a new shirt and skirt. Or better yet pants. Wait did Twilight own any pants? She couldn’t remember seeing any. Oh wait, first she should get out of the dirty stuff. Moving to a full-length mirror to make sure she wasn’t somehow screwing this up, she grabbed the hem of her shirt and pulled it up and overhead.
“Heh nothing to it, I don’t know… why…” Staring back at her in the mirror was Twilight in her bra, exposed for all to see. Pure black and rather lacy, and while it felt fine on her, Twi’s double D’s appeared to barely fit in it. Without thinking about it, she arched her back letting her chest stick out a bit more.
The look made her… proud somehow? Blah, this wasn’t her body. It was Twilight’s. She needed to stop thinking of it as her own. Yet looking at herself like this. It was scary how natural it was all starting to feel. An odd yet pleasant warmth ran through her. Twilight was beautiful. Even as a dog he knew that. Now it was her beauty staring back. Her body.
She shook her head. This was all too weird and wrong. Best to focus on changing. Next up was the skirt. It took some fumbling, but she managed to undo it and let it fall to the floor. Leaving her in just her underwear and socks. Again the image was something else. The panties were also black, and matched the lacy design of her bra.
“I-I’m beautiful…” She said, staring in the mirror drinking it in. Eventually she snapped back. “I mean Twilight is beautiful. Remember Spike, this is her body, not yours.”
Somehow that made her… sad? It hurt somehow that Twilight had all this. These looks, the ability to eat chocolate, the height, thumbs! These curves. Before the sunset, this would be taken from her. Taken away and she’d be back to her normal dog body.
“I-If I could keep this somehow…” Her hand touched her reflection. She sat there for a few moments before once again shaking the thoughts away.
“What’s wrong with me? Am I jealous? Jealous of her human body?” Maybe, though she hoped that wasn’t it. That’d be horrible, as no way could she refuse to swap back. True having this body was becoming more and more fun as time went on, but to betray Twilight like that?
No. Not in a million years.
She sighed, walking back over to the dresser to find a new shirt. She’d just have to be content with today. Content that she at least got a taste of being human, but she wasn’t going to keep this body. She wasn’t going to hurt Twilight.
A sudden pressure caused her to cross her legs.
She was, however, going to use the bathroom.
She was nearly outside, her hand on the doorknob before her brain kicked in. The heck was she doing!? She wasn’t a dog! She was human right now! Humans didn’t go to the bathroom outside in only their underwear. At least not unless they drank that other stuff he wasn’t allowed to have.
Rushing to the restroom, she closed and locked the door only to stare at the toilet as a dawning realization crept over her.
How did this work exactly? Uh well he always saw Twilight sit down? He also knew she’d need to pull down her panties. Doing so, she caught her reflection in the bathroom mirror. Glancing over she gulped. Somehow doing this seemed really… risque.
Ignoring her reflection, she finished pushing them down and went to sit on the toilet, only to flail wildly before catching herself on the cabinet. What? Oh right, the toilet seat was up. Wow no wonder they hated that. Pulling it down, she sat and… tried to relax.
“Oh! Oh this is weird! THIS IS SO WEIRD!”
* * *
“Any luck yet?” Twilight asked as he walked around the park smelling this and that. Much to his chagrin, he’d just stopped himself from sniffing yet another dog’s butt. It really was a powerful urge.
“I think so!” Fluttershy called back as she finished chatting with a bird. “We’re pretty sure we know where it is, and I have something we should be able to trade for it.”
“Trade? Why not just take it, it’s not the crow’s item to begin with!” Sunset growled trying to keep an eye on Twilight while helping out Fluttershy. The longer Twilight was in that body, the more Sunset worried. The swap was haphazard at best, and she had no idea how stable it really was or how much of ‘each other’ went into each of them. Already she not only saw him sniffing butts, but had to prevent him from digging up some flowers, among other things.
“If we try force, she’ll just fly off with it.” Fluttershy responded with a frown. “An even trade is best. Unlike Spike, most animals have…simple thoughts. She’s not going to recognize or care that it wasn’t hers to begin with.”
“Right, sorry Flutters I’m just…”
“Worried for Twilight.” Fluttershy finished putting a hand on her shoulder. “I know.”
“And we left Spike in her body at home. No telling what he, she is getting up to. Top that with Twilight hiding something from us…” Sunset sighed letting some of the tension out. This day was proving to be way more exciting than she wanted. “I just want this over.”
“Me too, we’ll fix this I promise.” Flutershy smiled at her, slowly drawing out one of her own.
“Thanks Fluttershy. I mean it.”
“Anytime.”
Twilight meanwhile, was trying to prevent himself from getting antsy.
I can’t believe this happened. I try to help Spike and I end up as Spike! He thought as he shuffled around. Taking another sniff, a rather pleasant aroma made its way into his nostrils.
Mmm that smells nice. I’ll go check it out. Then we’ll find the geode, swap back and I can… I can finish the experiment… I can give Spike the chance… I have to. I have to make this work…
The smell was powerful and… intoxicating. He’d never smelled anything like it before. Moving along, he soon came to a few other dogs playing around. For once he didn’t have the urge to sniff a butt. Instead he was drawn to this one blue furred one. She was tall and proud and regarded him with a curious, yet inviting expression.
“H-Hey there pretty. Do you smell that? It’s so good right? Smells like…” He got closer, barely registering the name tag on the girl’s coller. “Ember huh? Nice to meet you Ember. Now about that smell it’s…” He sniffed again.
“Coming from you! Wow! You smell so… so good I…”
Ember gave him a playful little yip before turning around and raising her tail. Twilight didn’t know why, but that spurred something in him. He felt something below start to stir. He needed… needed to do something…
“I’m sure Spike is fine, he’s not a little puppy anymore.” Fluttershy said as they began to walk toward where her bird friends had directed. “He’s grown into a fine dog, and I’m sure he…” She blinked.
“What?” Sunset asked, trying to see where Fluttershy was looking.
“Where's Spike? I mean Twilight?”
“Huh?” Her eyes darted around. “I-I don’t know! He, I mean she was just here!”
“Twilight? Twilight, where are you!?” Sunset called walking back the way they came, fear gripping her heart. What if something happened to them? What if they got dognapped or something? She had to find him!
“Um I’m sorry friends, but have you seen? Oh you have? This way?” Fluttershy asked softly as a couple of squirrels led her toward a place they said they’d seen her little purple friend. As she made her way over, she quickly made out the form of Spike.
“Oh there you are Twi-” Her words died in her throat as she saw exactly what Twilight in Spike’s body was up to. Mounted perfectly on another dog. A bitch in heat.
Her face turned lobster red. “O-Oh my!”

“Okay I’ll gladly go back to being a dog if I don’t have to deal with THAT again.” Spike shivered as she sat down in the kitchen. Her quest to change clothing was temporarily forgotten, leaving her still in just undergarments.
That had been the most embarrassing and awkward moment in her, or his life. Not only did he have to touch her body, but he had to figure out how ‘wiping’ worked. The entire ordeal left her frazzled.
“Ugh, I think this is what they mean by needing a drink.” She sighed trying to wash the memory from her brain. Geez, if that stuff really did what she’d heard.
Looking up her eyes caught sight of a bottle of what she believed Twilight’s parents had labeled ‘vodka’ sitting on the kitchen counter. A half bottle by the looks of it.
If chocolate was that good then did it mean this…
No. No this was different, she did know that. Yet, Twilight had been able to drink a little here and there on Holidays. So maybe just a little?
Again, when would she ever get another chance?
Bringing the bottle over, she stared at it. Should she drink straight? No, that’d be disgusting. They hated it when she did that to any drink that wasn’t her water bowl. Even the toilet. Ugh, toilet. Thinking of it, he couldn’t believe when he was a puppy he’d drink from that. Thank goodness she is all grown up now. She glanced at her chest. Really grown up.
Okay when Twi’s parents did this, they had a small cup. Searching around the cabinets, she relished in the fact she could even open these and search through them with such ease. Man was she going to miss being human.
Finally finding one, she sat down and once more examined the bottle. Slowly using her hands and fingers to unscrew the cap, she set it aside and took a whiff.
“OOF!” She cried, pulling her nose away. This stuff smelled horrible! Why did humans drink this? Well that was what she was here to find out. Pouring herself one tiny glass she brought it up to her lips. It still smelled horrible, but the taste was the important part right? Chocolate had been like eating joy after all. This could have a similar sensation.
Holding the glass up she took a few laps with her tongue.
“BLEH! How do they drink this!?” She nearly dropped the cup in her hand. It was revolting! Grabbing the bottle’s lid, she vowed to close it up and never think about this again. There had to be some mistake. This stuff was not good! Not good at all!
“Definitely a mistake.” She said to herself. “I can’t believe they…”
Wait, that's right. When her, or rather Twilight’s parents drank this stuff, they took it all in one gulp. Could that the secret? Was she just drinking it wrong? Well guess only one way to find out.
Gripping the small cup once more in her hand, she steeled herself and downed the entire thing in one go.
“YUCK!” It wasn’t any better! It wasn’t any better at all!
“I don’t get it, I did what they did.” She moaned trying to forget the taste of it. What was so good about this stuff? Though she supposed she did have the same reaction they usually did when they took a drink. It was baffling they’d ever go for another.
Her mind once again thought about what she’d seen the parents do. Velvet would always drink three, what did she call them? Shots? Three shots and claim that was the ticket. Was that it? You had to drink more for it to work? Why would you ever drink one!?
Again she prepared to put it away before she hesitated. As Spike he was forbidden from going near this stuff. If she was to ever figure it out. It’d have to be now.
Trying to keep from making a face, she poured another shot. Taking a moment to work up her nerves again, she gulped it down. Nope, still horrible, though her tummy did feel a little warm this time. Hmm.
“Well, three times the charm.” Another pour, another shot.
Okay now something was happening. Not only did she feel really warm, but everything seemed… floaty? She giggled. Her head felt all light all of a sudden. She licked her lips and grimaced. That might be so, but this stuff was still bad. Deciding enough was enough, she put the cap back on the bottle.
Huh that’s funny. It's a bit harder to do then it should be right?
She fumbled a bit, but managed to get it back on. Standing up to go put the bottle back, she had to brace herself on the table as the room shifted slightly.
“Whoa…” Mom and dad never mentioned this! Doing her best to stay upright, she wobbled over to the counter and placed the bottle back where she got it. How weird, she felt light and heavy at the same time? What did it do to her?
Heh, not that it mattered. She felt strangely… good. A bit frazzled maybe, but good. This female body was so much fun! Why was she nervous about it before? It was awesome!. After all she had boobies for crying out loud!
Looking straight down she smiled at the two lumps that jutted from her body. These were really her’s right now weren’t they? She’d been so afraid to touch them, she wondered why? Reaching up she cupped them in her hands, shivering at the sensation.
“W-well that’s different…” She breathed as her body swayed a bit, hands gripping her breasts. The sensation was so foreign and yet. It was kinda nice. She squeezed one harder.
“Ah!” She cried as a jolt of pleasure shot up her spine. What was that? Spike had certainly never felt anything like that before!
Squeezing again, she felt another jolt of bliss. Right hand, left hand, bliss bliss bliss! Mmm, having boobs was awesome! Maybe she could get someone to help play with them sometime? That sounded really nice…
Putting aside her boobs for a moment, there was another part of her body that was feeling off. It felt like she was, peeing almost? No that’s not right, she had already emptied her bladder, but it felt kinda weird down there.
Curious she reached down into her panties to feel around. The moment one of her fingers brushed against her new area down there, her knees buckled and she found herself kneeling on the floor, her mind spinning.
“W-what?” What happened? All she did was poke a finger across this… slit? She knew it had a name. Cat? No, that's not right, but it was like a cat. Pussy? Yeah that’s it! She brushed her pussy and-
“U-UHHHHHH!” She cried, her body twitching at the sensation. As a dog, he didn’t exactly pleasure himself. It’s just not something dogs really did. Even if he did, there was only one part of him that could feel anything. So this… being able to touch yourself and feel it through your entire body? Clearly this was the better body! She really was going to hate giving it back up!
She began to rub quicker, harder. Her other hand still gripping her boob began to do the same. Her mind flooded with static, her body quickly moving on its own. Before she realized it, her fingers jammed themselves inside her, causing her to cry out much louder than before.
Her body spasmed, her tongue rolled out as she panted like the dog she had once been. This… this was so… it wasn’t fair. She wanted this. She needed this! She wanted to feel this again and again!
More and more she probed, more and more her body responded to her touch. Was this what it meant to be human? To be female? Twilight was blessed! She was so blessed!
As she rubbed her breast she realized something else was happening there. One of her nipples was hard? That’s weird. She poked it with a finger and shuddered again. Oh wow! That sensation! She flicked it, eliciting another loud moan from her lips. More! More flicks, a pinch! Her mouth opened wide, letting out all sorts of sounds he’d only vaguely been aware of Twilight being able to make!
Would this happen to her other breast? She swapped hands. Oh yes! Yes it would!
Her back arched as she lay there furiously playing with herself. Still she needed more! More! Then upon stroking a finger into her now soaked pussy, she brushed against something that caused her mind to blank for a second. What in the world was that!?
She poked it again, another jolt. Intrigued, she began to rub. This time her brain simply seemed to skip forward in time, all sense of time out the window. How could this little nub inside her give her so much pleasure? Such mind-melting bliss!?
“Ah! Ah! Oh god yes! YES!” She was a mess now, her head laying to one side, tongue out as she continued this ritual. She couldn’t stop, couldn’t think. All she could do was forge on! Had to reach the end! R-Reach…
She had no idea how loud she screamed as the world crashed in around her. Her vision had gone blank, her nerves exploding like fireworks. It took a few moments for her mind to even return to her. Slowly making her aware of her laying on the kitchen floor.
Masturbation. She’d just masturbated until she came. Came In Twilight’s body.
With a start she sat up staring horrified at the sight of her pussy. Something weird and sticky had soaked the floor. Something that came from her. W-what had she done? Twilight had trusted her! How could she do this?
Still, it had felt so so gooooood.
Shaking her head she quickly moved to grab some cleaning chemicals and paper towels. No matter, she just wouldn’t tell Twilight about it. She couldn’t tell Twilight about it! She’d just clear this up and pretend it didn’t happen.
After several minutes she felt she did enough of a job to mask what had happened when she noticed her own appearance. Yeah Twilight would know something is up if she returned her body like this. She was going to have to shower. Yet that leads to more problems.
Namely she was practically naked, and to shower meant all the way naked. She remembered hearing several of the girls complaining about how hard it was to put on a bra, so she had no confidence that her, a freaking dog this morning, would be able to do that.
Well not like she had a choice. She’d die if she had to explain to Twilight why her body was covered in its own juices. Going back into her bedroom, she began to gather up what she was going to change into when a certain drawer caught her eye.. A drawer he had found by accident what was hidden there.
No… No she’d done enough in this body. She couldn’t. So why was she opening the drawer? Why was she pulling it out!?
Sitting there in her hands, was a very big and thick purple dildo.
“No Spike. Don’t think about it… Don’t you do it!” Moving it downward she brushed its tip against her still very much exposed pussy, giving another lustful shudder as she did.
This was wrong. This was most certainly an invasion of privacy, and no way she could do this here without Twilight finding out! She’d never be able to clean up here! Her eyes turned toward the bathroom.
“..Isn’t the shower clean?”
Half an hour later, her moans rang out through the house once more. She thought her finger had been doing a good job, but this! She pressed herself against the shower wall as the water rained down upon her body. Somehow the mere sensation of it over her, right down her tits turned her on. She was dirty! So dirty! She needed to get clean. If only she had a big strong man to help her!
Another moan erupted from her as she shoved the dildo in as far as she could get it without hurting herself. Did Twilight imagine it was Timber Spruce’s dick? She found herself trying to imagine him, but found herself losing interest. No Timber was Twilight’s boyfriend. Weird as it sounded, imagining him felt like cheating somehow? Someone else? Big Mac? Maybe Flash Sentry?
No, they were both kinda hot, but something was lacking. What was it? Maybe if she imagined someone she knew better?
Microchips floated into her mind. In the past he had Twilight help him study a few times. Spike liked him. He was into the same kung fu action movies he liked. They’d always end up watching one before Micro went home.
Now Spike imagined herself in this body. Sitting next to him… She’d snuggle up closer, grabbing his arm. Letting her breasts press against it.
Her body began to heat up again. Was it because of the hot water?
Then, then she’d reach over and rub his lap. Y-Yeah that sounded good. She’d get him nice and hard, t-then as he smiled at her, she’d move down, pull it out and open her mouth…
She felt her mind short-circuiting again. Her mouth open wide, eager for something to be inside it. W-what was happening? What was she doing!? She imagined the dildo wasn’t held by her, but rather it was Micro’s dick.
She had pushed him down on the couch now and had stripped herself. Smiling down at her, she marveled at how he’d play with her boobies.
In the shower her hand once more shot up to tease one as she continued to manipulate her dildo.
Then… then she’d raise herself up… s-she’d hold her pussy above his dick.
The dildo pulled out, mirroring her fantasy as its tip pressed against her slit.
She’d tease him then, grinding her hips, but keeping herself just out of reach.
The dildo brushed against her pussy, causing another moan.
She stares at him. In lust and longing. She’d dare him. Dare him to take her. To make her his. Claim her like the dirty slut she is!
Once more she felt herself fall to the floor as her body went limp, the world around her washing away with the water. She was no longer in that shower, but on that couch with Micro. He was so handsome now, so sexy. His dick so large. She wanted it, needed it, and he could have it, have her. He just had to take it!
With a scream she jammed the dildo inside her, her fantasy showing Micro grabbing her hips and pulling her down.
It felt so much better than before, her nerves once more burning like fire. If only… if only he was really being penetrated by a real dick. If only she could feel his hot seed flowing into her. Breeding her.
Oh how desperately she wanted it!
The dildo eventually slipped from her grasp to roll toward the drain. That… Why had she thought all that? She didn’t understand what was happening anymore. She needed to shower for real. Get cleaned up and put on some fresh clothing.
Still, one thing was very clear.
Being a girl was freaking awesome!

“GAH! I can’t believe I did that!” Twilight cried as they sat on a bench in the park. While Sunset… dealt with what they found Twilight doing, Fluttershy had gone off to get the geode. The very stone held tightly in her hand.
“You can’t really blame yourself. It’s those dog instincts…” Fluttershy added helpfully, though it did little to make Twilight feel better.
“Still I… we.. gah!” He wanted to vanish. “I want to just bury myself and forget everything!”
“N-Now now..” Sunset said meekly. In truth what do you say to this? Twilight in Spike’s body had likely just given a cute female doggy some nice puppies.
“All this, all this because I just wanted to give Spike some dragon traits so he wouldn’t-” His mouth snapped shut.
“Okay Twilight spill.” Sunset finally demanded. “I’ve been avoiding touching you this entire time so I don’t read your emotions, but I know something is up. Why are you so intent on getting back to that experiment?”
“Yes please talk to us.” Fluttershy added in. Twilight stared at them for a moment, almost looking as if he wanted to run before finally relenting.
“F-fine, uh… Well it came because of a movie if you can believe it. All from that movie I saw what, two months ago?”
“What movie? Twilight what happened?” With a heavy look, Twilight looked up at her.
“Sunset, what am I right now? What is this body? A-And do you know how long I’ve even had Spike?”
Sunset was naturally confused. “Uh, as long as you remember right? And he’s a dog, so what?”
“Oh!” Fluttershy cried covering her mouth. “I-I never… Oh Twilight!”
“What? What is it!?” Sunset was getting annoyed glancing back and forth between the two. What wasn’t she getting?
“Sunset in the movie, it was your typical boy and his dog flick. It was about how they grew up together, played together, but… but at the end of the movie…” His voice cracked, letting the silence swallow them.
It suddenly snapped into place. Sunset felt the life drain from her. “The dog… he..”
“Dogs usually only live about ten to thirteen years on average…” Fluttershy’s voice was quiet. Very quiet.
“Twenty at best.” Twilight added. “Spike… Sunset I don’t know how much longer he has. I mean I knew it’d be hard to lose a pet, but Spike? Spike talks Sunset. He sings, he has dreams and ambitions. He… He’s like a little brother to me in a way, and yet… o-one day…”
Sunset gripped the bench she sat upon. “That’s why you’re trying to infuse him with dragon energy.”
Twilight nodded. “I hope it’ll expand his life force. G-give him more time.” His body shook. “I can’t let him die so soon! I can’t. Not like… I have to try something!”
They sat there for a while. Silent and thinking. It was true. Spike wasn’t just some dog. They all loved their pets, and it’d hurt so much when they left, but Spike? Spike was more than a pet, more than a dog. He was their friend.
A friend that if left alone. Might not be here when they finished college.
The revelation was staggering.
“Then… then we help you Twi.” Sunset said, her voice firm. “We find a way to make this work, or we find something else.” Twilight looked up at her with such a thankful expression. Poor Twi. She’d been dealing with this for two months on her own. She couldn’t imagine how much this must have been eating at her.
“Me too!” Fluttershy chimed in, “And I know the rest of the girls would feel the same! We’ll all help!”
“Girls…” Twilight sniffed, it was so weird crying in Spike’s body about Spike. “Thank you. I-I’m sorry I should have talked to you all about this sooner, I just. When I realized this I just jumped straight into trying to find a way…”
“I understand Twilight. I can’t say I wouldn’t have done the same.” Sunset replied, taking Twilight’s paws in her hands. “But first we need to get home and swap you two back.” With that she placed the geode around Twilight’s neck, letting him use magic again.
“Right, best we do that before anymore-” As he spoke his voice suddenly rose several octaves, “-side…effects.”
“...”
“Sunset?”
“Yes Twilight?”
“Did my voice just become my normal girl voice again?”
“Y-Yeah it did.”
“Yeah we should probably hurry back.” Fluttershy finished.
***
Spike had just barely managed to get cleaned up and dressed before the girls came home. She had expected Twilight to interrogate her right away on why she no longer had a skirt on. While Twilight did question it, she bought Spike’s ‘story’ of it getting caught on something and him not being able to put it back on. It was partially true. As she wasn’t a girl before, or even human she had NO idea how to put that or a bra on. The bra part was something she hoped they didn’t notice until after the swap back when he’d be able to run and hide somewhere not here.
While Sunset and Fluttershy did give him questioning looks, Twilight herself barely seemed to notice anything. Had something happened out there?
“Okay so are we ready? I’m sure if we do the same thing last time, we’ll swap back.” Despite her dread at Twilight discovering all she’d done in her body, she couldn’t help but giggle at hearing Twilight’s voice coming from her body.
“I’m sorry it’s still so weird hearing your voice coming from my body.” Twilight huffed, but couldn’t really deny it was a bit silly.
“Though why don’t I sound like me?” Spike added, still speaking in Twilight’s wonderful soprano. “It’s like you became more you, but I didn’t become more me?”
“That is a good question…” Sunset added. She had a bad feeling about this, but it’s not like they could avoid swapping back.
“I have no idea, but that just proves we should probably swap back sooner than later.”
“Oh I do so hope you figure this all out. I’d love to be an animal someday.” Fluttershy added. Despite that statement however, both her and Sunset were as far away from the machine as they could get. No sense in further complications.
“Yes, well we’ll look into all of this after I’m in my real body again. No offense Spike but one day as a dog was enough.” He tried to keep the blush from his cheeks. He could NOT under ANY circumstances let Spke know what he did in his body!
“Eh it takes some getting used to.” At the same time Spike didn’t want to admit that he was going to miss this body way too much.
But… this is how it had to be.
“Okay ready? One, Two, Three!” As they had this morning, Twilight in her dog body began to draw out as much magic as he could, his body glowing and floating into the air. Spike wearing the scale waiting for it to begin sparking like before. Once the machine was going crazy again, she shut her eyes.
Being a human girl… Can’t believe I actually wish I was one.
Without pause, she reached out and grabbed the geode. This time there was a pulse of power as it began to glow brighter and brighter. Huh that’s not what happened last ti-
A huge blast of energy ripped through them as it was followed by a blinding flash. Spike felt her body jolt before everything went black.
“Twilight? Spike? Are you both okay?” Sunset called cautiously as she made her way into the smoking room. The machine this time was kaput, there was no salvaging it this time. “Twilight? Where are you!?”
“Here!” Cried her voice. With some relief, Sunset noted it came from the side of the Room Twilight’s body had been. Did that mean it worked?
“You uh you?” She asked. A frazzled Twilight Sparkle stood up and felt along her body before cheering.
“It worked! I’m me again!” She squealed jumping up and down. Sunset laughed and gave her a hug, as did Fluttershy.
“Welcome back Twi!” Fluttershy beamed before blushing. “Um are you not wearing a bra?”
“What?” Twilight asked, quickly peeking down her shirt to notice she was indeed bare. What the? She knows she put one on this morning!
“Spike! Spike where are you? I have some questions!” She bellowed, suddenly taking a deeper look at some of the things she noticed coming home.
Several seconds went by with no answer, though they could hear a shuffling on the other side of the room.
“Spike? You okay?” Now she was worried. If he’d gotten hurt, she could just be mad at him later. Besides it wasn’t like she had been an angel in his body…
“I-I think something’s wrong!” They heard a voice say. It sounded almost like Twilight’s but with a slightly deeper tone? The problem was it was still very feminine.
“Oh no! Did you get stuck with her voice?” Fluttershy cried in concern, trying to help wave away the smoke obscuring their vision.
“N-Not just her voice…”
“What do you- OH MY!” Fluttershy covered her mouth as her friends both peeked over themselves before mirroring her expression.
There, sitting naked on the floor with only a collar around her neck, was a very human girl that looked almost identical to Twilight. For the exception of the very dog-like ears and tail. She looked like she just stepped out of an anime.
“T-Twilight? Girls?” The very nervous, and very much human female Spike said with a shaky voice. “W-what just happened to me!?”
Fluttershy said it best.
“Oh my!”
Author's Note
If I'm lucky I just got this in.
The month sucked and I really thought I wouldn't be able to do this, but when I found I had one more day to get this written. I went all out and somehow did it all in this one day. >_<
As such I'd be surprised if it does that well, but I'm at least proud I was able to do it!
