"Twilight, are you sure that you know what you're doin'?" Applejack drummed her fingers on the table. "What if somethin' goes wrong?"

"You won't have to worry about that!" Twilight looked up from the anatomy book she had been paging through. "All body modification spells have failsafes built in. Everyone has an inherent magic field that naturally resists and magical effects on the body. I designed the spell so that if it doesn't enact it's primary function, it will automatically discontinue any endeavor to circumvent your inherent resistance, and self terminate."

Applejack's eye twitched. "Care to say that again in English?"

"If the spell doesn't do exactly what it's supposed to do, it'll fizzle."

"And what if it does work? That's kinda what I'm really worried about."

"Why?" Twilight finally looked up, confusion evident on her face. "If everything goes according to plan, what's the problem?"

"It's just...how long are the, uh... the results of the spell gonna last?"

"Well, I can't say exactly, but extrapolating from my knowledge of other transmogrification spells, if I only involve the minimum amount of magic required for the spell to take effect, it should naturally dissipate within a day. Eighteen to twenty hours would be my best estimate."

Applejack swallowed. "That long?"

"Well, I could also reverse it without much difficulty. If you're the one who constructed the spell, dispelling it is trivially easy." She grinned. "All things considered, there's no reason for you to remain in an altered state for more than a few minutes."

"That's all well and good, but why do you wanna test it on me of all people?"

"Well, Fluttershy and Rarity would never be willing to do it. Fluttershy would be too scared, and Rarity puts so much effort into maintaining her figure she'd never let me mess with it. Rainbow Dash might be up for it, but it would probably interfere too much with her training. Pinkie..." She shook her head. "No way in hell. I shouldn't even need to give a reason."

"Yeah, that wouldn't end well." Applejack sighed. "I guess I'm the only one left, then."

Twilight nodded. "Shall we get started, then?"

"I guess we might as well."

"Good!" Twilight clapped her hands and sprang from her seat. "All you have to do is stand right there. Give me some room to work."

Applejack reluctantly rose and stepped into the gap between the stacks of books. "I don't hafta be naked or anything for this, do I?"

"Weeeeeellllll.....It would be easier to perform the spell if I didn't have to account for clothes, but for the sake of your modesty I'll let you keep them on. Besides, I've already accounted for clothes anyway." She paused. "Although it would be easier if you took your hat off."

"Okay, that I can do." She tossed her hat on the table. "You're sure that you'll be able to undo this, right?"

"Of course!" Twilight cracked her knuckles in preparation, even though she didn't need her hands for the spell. "Let's get started. Try to hold still." She closed her eyes and began to draw in as much magic as she could muster.

Applejack swallowed hard. She could feel the energy swirling the air around her, preparing to strike. Twilight's eyes snapped open. They shown a bright white with magical power. The energy circling around Applejack plunged into her. She gasped. She felt the mana flowing through her veins, tightening her chest, making her heart beat faster. It started to burn with a heavy heat, crawling through her body. Mysteriously enough, it crawled down her torso and up her legs, building up right at her crotch. She tried not to think about why it was there. Then there was an enormous flash of white light, and everything was suddenly back to normal.

Twilight stood in front of her, rubbing her eyes like she always did after she turned out a big spell. She shook the brightness away and stared at Applejack. Her face fell.

"Crap," she snorted. "You're still a girl."

Applejack looked down, and noted that her breasts were still exactly where they had been a minute earlier. Even if the spell had been a bust, she was rather relieved. She reached up and gave them a solid squeeze to make sure they were still there. "Yup, I sure am."

"Damn it!" Twilight stomped forward and grabbed Applejack's boobs herself, giving them a good, long kneading. Satisfied that they were, in fact, there, she pressed her palms against Applejack's cheeks for a moment before running her hands down her torso and over her hips. "Yeah, you're definitely still a girl. The spell is supposed to change your bone structure and everything. It obviously didn't."

"I'm sorry, Twilight. I can't say I was all that keen on gettin' turned into a boy, but I do wish you'd have gotten the spell figured out." She took a step forward with the intent of putting a reassuring hand on her friend's shoulder. She stopped mid-step, her thoughts suddenly somewhere else entirely.

Twilight snatched up her notebook and began to flip through it, reviewing her notes. "It doesn't make sense! Normally if it failed all the energy would dissipate, but it didn't for some reason. I guess I should look over my calculations."

"Yeah, that would be great!" Applejack could feel herself starting to sweat. "You don't need me here for anythin' else, do ya?"

"No no, I want to check everything before I try it again. Maybe tomorrow."

"Great! I'll see you later then!" She made a dash for the door and disappeared down the street.

Twilight was too preoccupied with her failure to notice that Applejack's walk was slightly more bow legged than usual.

Applejack hurried towards the farm, each stride feeling more and more awkward. She should have known that Twilight's spell would have had some sort of unintended side effect. Well, this one probably wasn't entirely unintended, but it wasn't quite a side effect either. Hopefully it wasn't quite what she thought it was. At the moment all she knew was that her pants were a bit tighter in the front than they usually were. She burst into the kitchen.

"Hey, Applejack!" Apple Bloom waved at her, but Applejack barely noticed.

"Hey Apple Bloom glad to see you're workin' on your homework make sure you keep those grades up!" She would've taken the stairs two at a time, but she had a nagging feeling that doing so would be quite uncomfortable. She goose-stepped her way up to the second floor and darted into the bathroom, slamming and locking the door with such gusto that Apple Bloom could hear it.

"I guess, she musta really had to take a dump," Apple Bloom muttered.

Applejack paused a moment to take a few deep breaths and look at herself in the mirror. She looked exactly the same as she had before;feminine, yet strong features with a smattering of freckles over the bridge of her nose. Nothing else had changed, she thought. Twilight was no expert on anatomy, but she had obviously been right in her assessment of Applejack's femininity. Which made the bulge in her pants all the more inexplicable.

She fumbled with the button on her jeans and slowly began to pull down the zipper. "Don't be a dick, don't be a dick, don't be a dick, don't be a dick..." She muttered it to herself like a mantra, hoping that sheer force of will would make everything below deck go back to normal. With a deep breath, she let her pants drop to the floor. "Shit."

She had a penis. Her hand shook as she reached down. She shuttered as she confirmed, that yes, it was real, and yes, it was actually attached her. It wasn't too big, she guessed, maybe a bit longer than the width of her hand. It felt a bit like she was holding a sausage. A soft, warm sausage, that she could feel pulsing with her ever-increasing heartbeat. It was smooth, as it should be; it had only been there for about five minutes after all. She gently ran her hand along the shaft, and her heart started thumping even faster. Her hand reached the tip. The head of her penis was wrapped in a foreskin that hid it completely. The skin went past the head and ended in a tight pucker at the end.

She forced herself to breathe slower as she gently massaged the bit of extra skin for a moment. The feeling... wasn't unpleasant. Her index finger slowly began to wriggle it's way past the foreskin, peeling it back and exposing the head of her dick. Her fingertip brushed the head. She inhaled sharply. How could any part of her body be so sensitive? Even her lady bits had never given her such a rush from just a touch. She began to move her finger, drawing circles around the tip of her penis, letting the waves of zest flow wash over her. Then she realized, with a shock, that it was starting to change. It was getting longer, harder, it was beginning to lift away from her body of it's own accord. She drew her hand away from her cock as if it were on fire.

"No," she said to herself. "I am not goin' down that route." She shook her head. Her dick had only been there for a few minutes and she had already caught herself being tempted to jack off. It was too strange for her. Too unfamiliar. She couldn't use her new penis to masturbate unless she had actually come to terms with the fact that she actually had one now. Surely there should be other things at the forefront of her mind, anyway. Like what the hell had gone wrong with Twilight's spell to give her a dick and nothing else? Or how on earth she was supposed to get rid of it. It obviously couldn't stay. Sure, her farm clothes were generally not too form fitting, but panties weren't really designed to be worn by people with dicks.

She began to massage her temples, and realized a bit too late that she was using the same hands with which she had been fondling her penis. Oh well, she thought, it's technically a part of my body anyway. She turned around and faced the mirror, taking a long glance at herself. Twilight's spell hadn't messed around. In addition to the dick, she had received a generous pair of testicles. She reached down and gently cupped them in her hand. Soft, warm, and quite tender. How the hell did Big Macintosh put up with having all that stuff down there? She had once walked in on him in the shower. Needless to say, his package put hers to shame. If the decent-but-not-huge package she had was annoying, Big Macintosh shouldn't even be able to walk in a straight line.

She shook her head. There were more important things she needed to think about than her brother's dick. As a matter of fact, that was one of the last things that she ever wanted to think about. Surely other issues had to be more pressing. Like the fact that she was now at least 10% male. Maybe. She didn't feel any less girly than she had without the dick. Her throat shrank. What if she really was less of a girl now? She lifted her balls slightly, and reached under it with her other hand. She sighed in relief. Her girl parts were still there. Lips, hood, clit, vagina, it was all completely intact and right where it was supposed to be. Thank Celestia, she thought, everything is still there. That was good news, at least. But now the question remained. What the hell was she supposed to do?

Her head was beginning to spin. She flipped up the toilet cover and took a seat and began to mutter to herself. "Dammit. I can't go back to Twilight now. But how else am I supposed to get rid of this thing?" She lifted the end of her dick and let it slap down onto the toilet seat. "I guess I could just put up with it until the spell runs out. She said it would only last for like a day..." The prospect wasn't fun, but it sure beat going back to Twilight and explaining things. It would be uncomfortable, but she could put up with it. It couldn't possibly be that bad. By this time tomorrow, the dick would be gone.

Her heart finally began to slow down a bit. It was nothing to worry about. Twilight had never cast a spell with permanent effects. There was no reason to believe this would be any different. Applejack let her body untense itself. Now that she had, for the moment at least, come to terms with her cock, she realized that she really, really, had to pee. She sighed and let it flow. For a moment, the release felt lovely. Lovely, but not quite the same as it usually did.

"Wait, that ain't right." She looked down. "Dammit, that's not supposed to come outta there!"

For moment she tried to take conscious control of the muscles she had never controlled before and piss out of the portion of her anatomy that she had originally used. She succeeded, but only long enough for the last few drops to land in the toilet. She leaned forward and groaned. Her pants and panties were soaked. She took hold of her dick and shook the last few drops off of the end. "Twilight, what the fuck did you do to me?"

Apple Bloom poked her head into the laundry room. "What're ya doin' Applejack? Today isn't laundry day, is it?"

"I spilled somethin' on myself."

"Really?" Apple Bloom tilted her head. Applejack had never been a good liar.

"Really." Applejack just glared at her.

Apple Bloom glared right back. She couldn't see anything weird other than the fact that Applejack's pants were abnormally baggy.

"Are those Big Macintosh's pants?"

"No."

"So they are, then?"

Applejack's eye twitched. "Don't you have homework to work on?"

Apple Bloom sighed. She did have homework, and her sister's pants weren't interesting enough to be worth further pushing the issue. "Yeah. I'll get back to it."
