They Grow Up So Fast

Twilight Sparkle continued to pant from the heat that still irradiated off of her as Scootaloo stumbled into the library and put her hoof down on a shelf edge to steady herself. Scootaloo's fur was drying rather quickly despite the rain outside.

"Ummm, Scootaloo? Are you okay?" Twilight asked, feeling a lot more air headed than she had before. As she took a step to Scootaloo, her hoof shot back as Scootaloo gave out a cry; her wings shooting open and falling to the floor.

"Sooooo... HOT!" Scootaloo screamed as she arched up, pointing her upturned body to Twilight. Twilight tried to focus as her breaths on Scootaloo made the struggling filly shiver more. Without warning Scootaloo gave a grunt and Twilight's lips were now kissing Scootaloo's folds, only making Twilight's focus cloudier. Twilight's tongue shot out and began exploring the cavern that was presented to her.

Scootaloo felt the new object inside her and felt her entire body go out with a boom! The breasts she had been trying to keep from growing bounced out, her wings elongated with a large flurry of feathers, her hair also shot out in wild curves. She allowed Twilight to move on before seeing her pull away, making her feel angry that she would stop the immense joy she had only begun to experience.

Twilight wiped her mouth and gave a lopsided smile to Scootaloo, knowing that she wanted to get pleasured as well. At first she tried to open a drawer from the next room with her magic, but found that she had completely forgotten a basic telekinetic spell. With a giggle, Twilight decided to try and lead Scootaloo to the drawer by getting her up. Both of them locked lips, letting each others hooves explore their bodies.

Twilight moved her hooves all around Scootaloo, feeling the muscle and fur move as Scootaloo continued to age into a mature mare.

As Twilight nearly got to the drawer, Scootaloo moved up and gave Twilight a lick on her horn, making Twilight's magic fizzle momentarily and lighting the darkened floor. Scootaloo's eyes went to Twilight's, hoping that her pleading look would allow Twilight to continue her act. Twilight pulled out a vibrator, a plan formulating in her mind.

Twilight wrested Scootaloo to the ground so their rear hooves crossed over each other, their vaginas nearly touching each other with their own passionate kiss. Taking the vibrator, Twilight stuffed it between them and switched it on, making Scootaloo scream from the sudden shock of pleasure returning to her.

Twilight began rubbing against Scootaloo, making the vibrator dig further into her. Scootaloo unconsciously returned the favor as the two began to pump against each other in a simultaneous beat. the drawer began shuffling out with each bump and eventually fell, revealing sexual books and magazines alongside a double-ended dildo. Scootaloo's eyes fell to one page that was open, showing two mares in a room, with one having the double-ended dildo in her.

Scootaloo began pushing harder into Twilight until Twilight burst out in a climax, leaving Scootaloo to crawl to the new device and its secrets. Scootaloo moved the dildo to her own vagina and let the flopping rubber enter her, unconsciously sliding it back and forth for a few moments before looking over to Twilight, her rear up in the air as she was attempting to stand.

The rain began to fade as Scootaloo slowly got up, the new object in her snatch waving back and forth as she mounted Twilight. Twilight felt the dildo ram into her as Scootaloo pounded into Twilight with wild abandon. Scootaloo kept the pace as Twilight was pushed into the library wall, books beginning to fall around her. Twilight gripped onto any book she could and each one she nabbed would fall as she approached climax.

"Oh-hh-hh-hh, Ye-e-e-e-e-ss-ss!" Twilight gasped out between each beat.

Scootaloo felt the climax approach her and flipped Twilight around, not knowing her own strength. Twilight's back now bashed into the wall of falling books as Scootaloo kept her eyes on Twilight's. Both of them continued to watch each other as they reached climax. Twilight let out an eep and hugged onto Scootaloo. Scootaloo felt hers come and only paused momentarily to let out a hissing sound and continued her fast pace. Scootaloo's wings had been buzzing the whole time, kicking up papers, pens, and other loose objects around them.

Scootaloo felt her climax approach again, watching Twilight as she went wall eyed from the pleasure she was giving. Scootaloo finally gave one big pump and she felt her climax again, this time collapsing to the floor with a yell of satisfaction and on top of Twilight. The two of them kept to each other, the dildo still in each other as they fell asleep on the floor under the light of the new moon.

Applejack woke up before the morning sun came out, noting the wet ground outside due to the unscheduled rain from last night. She gave a few stretches to her back and shoulders before knocking on Applebloom's door to wake her up.

"Time ta wake up, Applebloom! You got a few chores to do before school!" Applejack yelled, knowing that Applebloom was usually a sound sleeper.

"In a m-m-m-inute!" came an older voice, shocking Applejack as she forcibly opened Applebloom's room. As Applejack entered, she could smell the stench of sex in the air, gasping at the mystery mare wearing Applebloom's bow and laying on her bed as she masturbated freely.

Applejack froze in place as the mare finished her act and lolled her head to Applejack, she saw the orange eyes of Applebloom staring at her.

"A-A-Applebloom?" Applejack stuttered, the former image of her little sister shattering at the sight of this adult mare that had the same mane, coat, and eyes looking right at her.

The mare huffed as she rolled off the bed unsteadily and gave a frightened look to Applejack.

"Yes."

Silence passed in between the two sisters as Applebloom nervously moved her eyes away from Applejack's stare.

"B-? How did-? Wh-?" Applejack tried to ask questions but found nothing. After minutes of trying to connect the dots a knock came at Applebloom's door.

"Hey Applebloom, is Applejack in there with you? We need ta get out and do our work."

Applejack panicked as she heard the door begin to open, if Big Mac found out that Applebloom was an adult, he'd freak out worse than she was. Applejack kept the door from being opened and tried to hide the sight of Applebloom from Big Mac's sight. "H-Heya Mac, I- I- I'm in here with my sis and- and- I was just about to go, be right out!"

Before Big Mac could say a word about the unusual stench coming from the room the door slammed shut and Applejack braced herself against the door, unsure of what to do at this point.

Applebloom tried to make her eyes look up to Applejack again, noting that she was near the same height as her. She had been feeling so good by touching herself and when she came in, she felt embarrassed. "I... I'm guessing school's not going to be an option today?"

Rarity awoke, stretching out her tired limbs. Taking off her sleep mask, she looked outside from her closed window and gave a smile.

"Such a grand day, the morning dew is still on the ground, ponies are all waking up and starting their own routines, and I cannot fathom a day like this to be wasted on staying indoors."

Rarity began her little skip to the shower, carrying with her a basket of her usual cleaning supplies. Loofahs, Shampoos, Conditioners, and a special blend of bath salts that when made wet would let out a wonderful lavender scent. Her focus was so strong on completing her usual routine, not once did she open her eyes to see a mare was using her shower, her ears would not listen to the dulcet tunes that came alongside the sound of running water. Once she had entered the bathtub however, she soon was face to face with the sudden realization of a mare looking right at her.

As the two mares screamed out, the shower was shut off and both mares were dripping water in the tub.

"Who are you?! More importantly, HOW DARE YOU INFILTRATE MY HOME?!" Rarity yelled out to the white unicorn with pink and purple mane.

"What? Hold on! Rarity-!" The mystery mare started.

"So you know me! No doubt you are some sort of stalker!"

"RARITY! Stop it! I'm your sister!"

Both of them went quiet, Rarity trying to understand what this mare had just said and the other attempting to get some soap out of her eye.

"That's not even close to possible," Rarity finally said, stepping out of the tub, ignoring the wet hoofprints she was leaving as she opened Sweetie Belle's room, finding the bed that Sweetie Belle would have still been sleeping in not only gone, but completely messy.

Rarity went back to the shower room to see the mare continuing her shower, singing a song.

When you're a younger pony

And your flank is very bare

Feels like the sun will never come

When your cutie mark's not there

So the three of us will fight the fight

There is nothing that we fear

We'll have to figure out what we'll do next

Rarity paused for a moment, she did think something was odd about the appearance of the mare in general. Something that seemed VERY out of place.

The water shut off and the mare moved the curtains out of the way, letting Rarity see that the mare had no cutie mark.

Suddenly things came to Rarity FAR too quickly, the coat, the mane, the singing, it kept pointing to what had to have been impossible.

"No... No, it can't be!" Rarity began her eyes going wide in shock. "Sweetie... you can't-"

The mare gave a small nod to Rarity, a small embarrassed smile on her face. "I didn't want to surprise you like this..."

Rarity tried to keep her focus intact, but fell to the floor unconscious.

Spike had managed to get woken up by loud bangs against the door, a feat that would've been deemed impossible if not for the urgency behind each whack.

"Oooorrrggg... I'm coming..." Spike groggily moaned out, stepping out of his bed.

Passing over multitudes of papers, fallen books, and even Twilight and a mare he hadn't seen before were glanced over as his mind wasn't fully awake to the unleashed torrent of action that had happened last night in the room. He gripped the door handle and gave a weak tug, making the pounding outside hurl the door open and flinging Spike across the room.

"TWILIGHT! AH NEED TO SPEAK TO YOU RIGHT NOW!" Applejack roared out.

In response, the cuddling Twilight woke up and gave a little stretch, giggling at the fact she had fell asleep with a dildo in her.

"I totally needed that edge off from last night, thank Celestia this mare came in and needed to do the same thing," Twilight said, her speech slightly lisped.

Applejack looked over at Twilight and was briefly puzzled at the mane color change. The mare's eyes were also peering off slightly in other directions. It almost didn't seem to act like Twilight, but she had the same coat, and the same cutie mark. She shook it off as perhaps a relative of Twilight's that stayed the night or something. After all, Twilight wouldn't have sex with a mare in the middle of her own library.

"Erm, hay-ya. Would you mind tellin' me where Twilight is? Ah... I mean, my sister has got a problem that may have started here."

Twilight gave a pout of disappointment to Applejack. "You don't recognize me?"

Applejack shifted her eyes around the room for a moment before answering. "Should I?"

Twilight gave a little laugh, "Maybe we haven't met, what was I thinking? Here I thought you were somepony I remembered..." She paused for a moment and put a hoof to her chin. "Actually, I don't remember nothing!"

She then gave a gasp, "Oh no! I need some new clothes! Perhaps some makeup, jewelery, and some more of these neat little things in this magazine."

Twilight lifted up the porno mag and Applejack's face flushed, half from embarrassment being caused by this mare, and the other half from getting no answers out of this airheaded pony.

Applebloom finally stepped in, looking at the mess that the room was in.

"Kinda looks like a tornado hit inside the treehouse," she murmered before looking down at the mare on the floor. Recognizing the coat and hair, she poked Applejack to get her attention. "That's Scootaloo! She got older-ified too!"

Twilight turned to her fallen guest and roused her for a moment. "Wakey wakey! Somepony needs to get cleaned up to go out and start clubbing all over again!"

Scootaloo gave a little hum to let the group know she was waking up. As she stood, her wings went open, engulfing the light coming from a nearby window and shut back to her. She turned about halfway before realizing she still had the dildo in her. With a slick pop, the rubber dong came out and hit the floor. Looking up, she saw Applejack hiding her face in her hat, Twilight skipping to her bathroom, and another mare gawking at her.

Before Scootaloo could speak, another slam of the door came, despite the door having already been opened. In the frame was a heavy breathing Rarity, tears going down her face.

"Twiiiiiliiiiight! My sister's been cursed!"

Sweetie Belle pushed past Rarity to enter inside, "I am not! Just... got taller, and stuff."

The trio all looked over each other as the room began to fill with conversation as to what was happening.

Spike gave a whistle, stopping the loud rambling. "Okay, it's fairly obvious what's going on here. Something magical has happened to the three of you that's made you into mares. Even more interesting is the fact that Twilight isn't really around... at least... I think she isn't. I can't help but think that blonde mare has to be her."

Spike's body jolted a bit in surprise, "What about her project to Celestia? Is it still-?"

Spike went upstairs before he finished his statement and came back down with the Midnight Flower.

"Hey! That's the flower that covered us in dusty stuff!" Sweetie Belle exclaimed.

"Dusty stuff?" Rarity asked with heavy concern, "You don't suppose this flower has anything to do with... with... with this unfortunate evil!"

"I don't think this is evil," Scootaloo said with a smile on her face. "Now we can do whatever the mares can do! Then we can get our-"

"Nuh-uh!" Applejack interrupted. "There ain't gonna be no crusadin' while we're still trying to figure out what's going on!"

Applejack looked around for some note or clue of Twilight's disappearance before she found a page that had a tiny picture of the Midnight Flower near the bottom.

"What's this?" She muttered before holding up the page.

"Knowing what this flower may do to you as of now, I as the author do hope you enjoy this piece of flora. If you find out that somepony you know or yourself have at any time these symptoms, fret not. Under the power of a New Moon can anypony that has been affected by these conditions return to when they were before.

It is also prompt to note that there are also ways to extend these symptoms under the New Moon as well. If a mare so chooses to continue her life as her new form, the time can be expanded beyond that month. However, it must be noted that if one so chooses to continue down the path that they have been afflicted by, they can be forever changed in mind, body, and more-so the spirit."

Applejack flipped the page over and found nothing more.

"So, when the new moon comes we won't be adults anymore? LAME!" Scootaloo huffed.

"We can do a lot in a month though, Scoots," Applebloom interjected. "And we can still be adults if we wanted to by the next New Moon!"

"I'm puttin' my hoof down at this, for all y'all," Applejack angrily spoke, her front hoof slamming down on the floor. "Don't even think about makin' this longer than it has to."

The trio gave a little groan, but then turned their attention to the flower.

"What should happen with that flower? Twilight's meant to take care of it," Sweetie Belle hummed.

Applejack gave a small thought over this. If Twilight was really gone, then getting any answers behind what the flower had done would be hard to come by.

"Uhh, Rarity. How about you take care of the flower for a little while? Just until this entire mess of our sisters hitting puberty way too fast gets taken care of."

Rarity gave it a little thought and looked over at the flower for awhile, it did look lonesome as it drooped slightly.

"I guess it'll be okay," she said with a little shrug.

"Suppose that takes care o' one issue," Applejack said to herself. She looked over at Spike and then around the room.

"I ain't the kind to be bossy or nothin' but make sure that if Twilight comes back that she needs to know that Rarity and I are looking for her, okay, Spike?"

Spike gave a salute, his small chest puffed out as he stood at attention.

Applejack then gave a sigh, knowing that this month was going to be torture trying to keep things from getting too rattled up by the sudden change of three schoolfillies becoming instant mares overnight.

Hopefully, some of the townsfolk would be understanding... maybe.
