With hurry Sunset did her way to the nearer lady restroom, her legs struggled a little but her urgency put pressure on them to move faster, her face got more red as she passed other students that greet her or wanted to ask her about something only getting quick waves or half asset answers in response, she knew what was causing her situation but there was no way to solve it here in school were she could be seen and heard.

Finally turning a corner she found her salvation not far she just needed to get there and she could- "Hi Sunset, would you mind helping me with this papers". Came the warm and caring voice of the Principal of CHS Celestia Regal.

Sunset cursed inside her head, her hand just inches from the handle of the door, she turned her head hoping her face wasn't a freaking red mess by now. "Sure Miss Principal Hurry I'm not in any Celestia... Uh? I mean... Sure thing".

"Thanks Sunset, it just to my office". Celestia passed a portion of her load to Sunset and motioned for her to follow, Sunset walked behind her trying with all her might to hold back her inner discomfort but some of it slipped through. "Are you feeling well? Your face looks a bit feverish".

"I-I'm ok Principal thanks for asking, maybe a little under but it's nothing serious".

"Good, you and your friends are going to start the last years here so keep it up and soon you'll be graduates".

"Thanks ma'am, will do".

"Oh... and speaking of graduates, Hello Big Mac, here to check on Granny Smith?".

"Heya Miss Celestia? Howdy Miss Shimmer, ah am here to give this to Apple Bloom, she forgot her science project". Big Mac pointed to a small set of seed glued to a square piece of foam that he was carrying.

"Ya seem to be in a pickle, here let me give ya a hand". Big Mac passed her sister project to Celestia and took her stack of papers from her and after leaned down for Sunset to pass him her own, however when she did so she stopped with her face just inches from his, in that moment Big Mac's smile changed to a confused look.

"Tha-thanks Big Mac but I have to go". Sunset pushed the papers into him a bit forceful and bolted out right away without another word.

"That was?... I'm sorry Big Mac i interrupted her in the middle of something, she probably was in more of a hurry that I thought".

"Ah don mind Miss, now then were do we take this fellas".

"To my office if you don't mind".

"Sure Miss". Celestia continued to her office while Mac took a last glance to the retreating form of Sunset Shimmer, an odd memory flicking in his mind and a familiar lingering scent still imprinted in his nose, he turned around following his former Principal.
_____________________________________________________________________
After another walk of shame Sunset finally did it to her destination, luckily for her the ladies restroom was empty and she could tend to her need, as she seated in the toilet Sunset picked up her skirt and removed her underwear, her fear was confirmed when her black panties came out with a wet spot in the middle of her crutch, she was aroused, she had been for the last two months and it had been nothing but torture from begining to end and getting worse as time went on.

It started a few weeks before the anniversary of her arrival in the human world, it was very tame at the begining, maybe a few times were she felt a tingling in her belly and a bit of discomfort when she moved too fast or sudden, then it was her mood who got worse when she ignored the first signs as something that would go away soon, she was very wrong, she started to get elusive dreams were she would trash around and would wake up with her thighs wet and sticky, she thought that it was just pee and embarrassed she stopped drinking liquids before bed but it didn't stop.

It wasn't until one of the sleepovers with her friends that Sunset found out the source of her problem when Rainbow explained with detail how she got a wet dream by watching a concert of one of her favorite bands, Rarity and Applejack told her to stop her shameful rambling but Pinkie jumped in the conversation and what was supposed to be a fun innocent night turned into a glorified tell tale of first time experiences, Rarity admitted to already had several of them before, Applejack too but she excused herself by saying that it was due to her mistake of drinking expired cider, even Fluttershy confessed to had a few already because a magazine that Rainbow left in her room one time after another sleepover in her house.

After that Sunset researched all she could about sex and feminine development finding her situation described as her body telling her that she was ready and mature enough to have coitus.

Of coursel her problem didn't disappeared by just finding it but it help her to understand, however her problem went from annoying to beyond when her body started to produce moisture in her private part in the middle of inappropriate scenarios such as the middle of classes or when she was out with her friends, then to rub salt to the wound her breasts were next on the list, her nipples especially became a point of extreme sensitivity, she didn't updated her wardrobe in a while and without much of attention in her part her breasts grow a bit making her nipples fight for moving space against her bra.

Her predicament only grew from there on, the tingles in her stomach became more frequent, her breasts only became more sensitive and her womanhood started secreting juices even during the day making Sunset's live miserable.

Fortunately Sunset found some release in the form of masturbation, while she was no stranger to the art of self satisfaction she only did it as a curiosity first but now she had to do it for real necessity, her first few times were awkward as hell but ber body pick it up rather fast, she did it only when she felt her symptoms were becoming to strong and it did help, however to her horror her body started to require the treatment more often, then came the smell, Sunset felt her social life would end when she detected a certain scent coming from her, it was subtle but it was there, to combat this new threat Sunset started using deodorant with a stronger aroma.

Her constant battles against her own body left her a wreck ready to go up in flames and her friends, her wonderful and special friends became the final nail in the coffin when her mood swings started to show up even more causing them to start question her and her personality, she felt frustrated of not been able to ask her friends for help.

The girls suspected that something was wrong with her and they came to the conclusion that she needed a party to relax and go back to her normal self, the party was thrown in Rarity's workshop and surprisingly it worked, Sunset felt bad for not share her problem with them and the party did help her relax if even for a bit.

The bliss of the party as awesome at it was lasted only for a couple of days, soon after that her body struck back with a vengeance to the point were Sunset needed a change of underwear everyday day, in her part time job thinks didn't fare any better, there was only so many bathroom breaks that one could ask of her boss, still Sunset marched on trying to enjoy her friends company and her personal life but little by little the glass got full.

"Ok girls, am I the only one who thinks Sunset is avoiding us? I mean I know that sometimes she have lunch with Trixie but now we rarely see her outside school and when we see her she's more cranky that Mr Doodle". Rainbow Dash said while chewing loudly at her sandwich.

Rarity who was eating a salad with carrots and a chicken slice spoke up too. "We have noticed but we thought that her party would ease her mood, seems to me she's dealing with something more complex don't you think?".

"That won't do! Nobody pass for one of my parties and leave unhappy!". Pinkie Pie proclaimed sticking her fork in her own chicken sending little bits toward Fluttershy.

"Maybe... Maybe we should ask her". Said Fluttershy while wiping her face of chicken bits.

"Have we already? And what did she said? First that it was her job, then that it was the tests, now she said that it was an itch... and itch? Since when is that even a thing!". Applejack roared over her friends but she calmed and blushed when the rest of the cafeteria turned her way.

"An itch could be explained under different number of physical and biological factors that... Sorry". Twilight stopped mid rambling when all her friends turned their eyes.

"Anyway, we should corner her and and and tight her up with AJ's lasso and and... "

"We get it Pinkie but forcing her is not gonna work, we have to be... uh what's the word?".

"Inconspicuous?".

"Yeah that, we hafta be incornpricksomething, ask her but lightly so she won't know what we are up to?".

"Yeah? But where and when? My dad still mad for the last time we party at my place and he still trying to get the smell out of his room".

"That's your own fault Dash!".

"Yeah but it was awesome!".

Everyone got a excuse to avoid been the host for another sleepover so they turned to their safe bet, Sweet Apple Acres.

"Fine! Yer just lucky Granny is taking Bloom to see our cousins in Florida".

"Uuuuh so it just gonna be us and... Big Mac?".

"Ah suppose, why?" asked Applejack with a bad feeling already settling in.

Pinkie, Rarity and even Rainbow giggled.

So with a plan done the girls send a text to Sunset who took more that normal to answer it but at the end she accepted. "Ok team, she's in now we just need to do it like this...".
_____________________________________________________________________
Sunset watched hopelessly the screen of her smartphone after she just answered the invitation that Applejack send her, she knew what this was all about, she had seen it in their eyes, the way they tried to ask her why was she avoiding them and their lack of believe when she give them an excuse.

This was no doubt a continuation of the party they did for her celebrating her 18 birthday that was actually more of a symbolic date that anything, Sunset declared her birthday the day Celestia took her in as her apprentice and since time was measured different here she then changed to the day she arrived in the human world.

A sleepover with the her friends and with no supervision would have been a reason for excitement but now that was the last thing in Sunset's head, her mind wondered to the only adult left in the Apple household, Big Mac, Sunset remembered the moment his face was just inches away from her making her fell goosebumps in her whole body and then some, not only that but she felt her heartbeat rise and her arousal worsen from all those.

Sunset couldn't deny that he was attractive, been close friend with his sister have giving her and the rest first row seats to his activities around the farm and boy did Big Mac liked to work shirtless, his physic left all male population in CHS in a far 3rd place, even Flash Sentry with who Sunset had a relationship for a time was a far cry from the farmer, most of all was the fact that he was by no means a one trick phoney as his charm included his gentleness and smarts, many have been the times when Sunset saw his kindness when helping his family or a complete stranger.

Both Luna and Celestia agreed that he was the best when it came to numbers, Luna even called him a nickname that apparently annoyed him. Even so Big Mac was never in Sunset's mind as a romantic interest for two main reasons, one been Applejack and the second been her failure with Flash Sentry, while Flash wouldn't admitted it was obvious that he wasn't able to pass his past fixation with Princess Twilight, to see her human double not only ignoring him but in love with some other guy upset him up real bad and Sunset was caught in the middle as a substitute, it took her a lot of time to figure this out and even more time for Flash to admit it to her face, so at the end they broke up and Sunset was left with a sour aftertaste in the romance department which she tried to ignore from then on, but now this problem showed up.

Shaking her head to dispel her naughty thoughts Sunset finished and cleaned herself, once ready to go back to classes she just hoped that she could keep her shameful secret to herself until she could find a solution.

FRIDAY...
Sunset sat in a corner of the library hidden as much as possible from the rest of the other students, the material she was studying was while not taboo it was very personal. She did make sure that no one stumbled upon her by accident while she read the sex educational book that the library had, the book was old, really old and it hasn't seen use in quiet a while if the dust was any indication.

Frustration settled in as Sunset failed to find any conclusive solution for her predicament, only explanation about the symptoms she was already experiencing, then it hit her, she was looking at it as a human and not as a pony, a mare, but then she was doom for sure, the sleepover was tonight and there was no way to go to Equestria and be back before nightfall and even then the solution may not even be easy to achieve, her only solution was to go prepared for anything that it could be thrown at her.

FRIDAY AFTERNOON...
Sunset didn't prepare enough, after school Sunset send a short message to Princess Twilight using her journal, asking for permission to use her library, as expected the answer came to late only when Sunset was at the entrance of Sweet Apple Acres, with that help out of the park her preparations included take a cold shower, use loose clothes that kept her fresh and mobile, pack her deodorant and an extra set of underwear should a disaster occur, and extra extra underwear should more that one disaster occur.

As Sunset did her way to the Apple house she heard some noises coming from the shack/garage in front of the driveway, Sunset was sure Big Mac was working in his truck, Applejack told the rest how much Her brother cared for his precious vehicle, trying to avoid contact Sunset moved pass the shack but Big Mac detected her presence and called out her.

"Someone there!".

"....".

"Hello?".

"Ye-yes?".

"Miss Shimmer? Do ya mind givin me a hand?".

"... Sure?". Sunset approached the truck and saw Big Mac's legs coming out from under the truck.

"What do you need me to do".

"Thanks, just take the driver seat and do what ah tell ya".

"Ok". Sunset did as instructed and sat in the conductor's seat.

"I'm on it, what now?".

"Ok... Push the brake pedal please". Sunset did so. "Now try the clutch... nice, hold it there for me... ok now the accelerator Miss... and done!". Big Mac started to come out from under the truck.

Please don't be shirtless, please don't be shirtless, for Celestia please. Don't. Be. Shirtless. Sunset prayed, to her relief the young man was dressed with a a sleeveless shirt that hugged his chest and abdomen tight but at least it was something, or so Sunset thought, as Big Mac approached she saw him a bit sweaty and mixed with the smell of motor oil she found the mixture a bit pleasing. No god dammit nose, don't betray me now!.

"Thanks Miss Shimmer,that's all ah needed".

"No... no problem Big Mac, a-anyway I gotta go, Applejack and the rest most be waiting".

"Make yerself at home Miss, oh and ya can help yerself to some of mah Apple fritters, they are inside the fridge with mah name on it".

"Oh hm thanks, ok see ya!". Sunset turned around with pink cheeks, she couldn't believe that she was again oogling at him, still her body betrayed her and involuntarily turned to see him one more time catching him as he doubled to pick his tools from the floor.Nice ass! Wait no, no no no no! I didn't just thought that about my friend's brother!.

Finally Sunset got to the house to find that indeed all of her friends were there already, as soon as she did her entrance the girls stooped their conversation and focused on her only.

"Finally here darling, for a moment I feared that you may have abandon us.

"Don't be silly Rarity, you are the best friends a girl like me could ever ask, why would I let you down?".

"Welp, now that yer here ah declare this party officially on!".

"Right on!".

"Yahoo".

"Excellent!".

"Yay!".

The party started out nice and easy for Sunset, her friends only focused on games, food, gossip and a bit about school and Sunset relaxed only taking a couple of bathroom breaks to keep her condition under control, however as the little get together continued the other girls started with their interrogation.

"So anyway Sunset, everything ok?". Asked Rainbow trying to be subtle.

Sunset stopped in the middle of her drink, from over the rim of the glass she could see all eyes focused on her. "Hm sure, I... don't thinks there's anything wrong right now, how about you?".

Rainbow didn't expected to have the question thrown back at her and looked to the other girls for support and Applejack came to the rescue. "We just thought that we may unwind a little if we talked and since we haven't seen much of ya recently ya may want to begin, what do you think?". A good excuse, a noble cause and Sunset couldn't be more happy to have friends that cared so much for her but in this moment their love was been a little to much, or was she just overthinking thing? Could she talk about her problem without feeling ashamed, they were girls after all, sure they had their own intimate problems right? Sunset was about to find out.

Something called Applejack attention from behind Rainbow and she reached out for it. "Dash! Why the hell did you brought this trash to mah house!". The object of insult was a adult women magazine that had a naked couple in the front, both male and female looked fit and in their early 30's maybe.

"What are you calling trash AJ? This... Is just awesomeness at its finest and this is not even what you think". Rainbow took the magazine from Applejack and put it on the center of the group so that everyone could see it.

The reactions were just as one could expected, Twilight and Fluttershy turned completely red and averted their sights from the stack of paper, Pinkie's eyes opened wide but she just got closer to take a better look, Sunset and Applejack also went red faced but for different reasons, while both were embarrassed Applejack showed disgust and Sunset showed fear, but it was Rarity who eventually reached out and took the cursed object.

"This is... Intriguing, Rainbow dear do this magazine include training regiment to... Ahem, reach this results?". Rarity asked while pointing to the woman's well fit abdomen and toned legs.

"Uh? I guess? Probably in the end".

"So you don't even know what the heck is inside? Asked a even angrier Applejack.

"Well duh! I just bought it in my way here, I wasn't even going to show it to you after what happened in Fluttershy's home". Fluttershy almost fainted just by having the embarrassing moment been brought out in her presence, one thing was to have your parents find porn in your room, another one was to have Fluttershy's parents to find porn in her room, poor Fluttershy was almost send to a sister's convent in order to purify his tainted soul, it took the combined effort of the seven girls plus Celestia's assurance that Fluttershy was a model student to ease her parent's worry.

"He he sorry again Shy, didn't mean to remind you that".

"That's... ok Rainbow, my parents are just... to sensible about sex and stuff".

"See what Ah'm talkin about, this kind of thing just bring trouble, yer learn about it when ya hafta and not before and NOT with THIS!".

"Aaaah come on Cousin! Didn't Granny told us that story how she and Grandpa Moonshine hook up, it was fun!".

"Pinkie... First Granny was drunk and second... She's Granny Smith".

"Girls, I think we are losing the point here". Twilight finally spoke up bringing the discussion to an end and making all the girls remember why did they have this sleepover to begin with.

'Dammit Twilight' Sunset couldn't help but fight a grimace as the conversation focused back on her. "Sorry darling but back on track, do you have anything you want to talk about? Maybe about work, fashion, lov-".

"That! Is off limits Rares and you know it, so please dropped, how about you tell the rest of us how are your new designs, I haven't heard of that in a while". Sunset found her mind starting to cloud from both her body starting to heat up and her epic failure in romance been reminded.

"If I may point out, the reason why you haven't heard goes back to the fact that you... kind of avoid us... we think?". 'Leave it to Twilight to attack me with logic'.

"You think that I'm avoiding you?". 'Yes I am and I so sorry'.

"You kind of doin it Sugarcube, everytime since before the party".
'So you noticed'.

"That's... I have some stuff that is bugging me, that's all". 'I just need time to figure it out, and why is getting hot in here?'.

"That's what you keep tellin us but I can see that yer not tellin the true, just tell us already!". 'So you can respond the same way you did with Rainbow's magazine? Fat chance! Hey girls you know what? I'm fucking horny most of the time and I've been masturbating to hold it down! Wanna talk about it?'.

"And I'm telling you that is just something temporal, I can deal with it myself, soon I'll be back to normal!". 'I hope is just temporal, that it will be over soon like a flu or a fever but... deep down I feel like this is just the begining'.

"Ah ha! So you admit that something IS wrong and yet you won't tell us?". 'Oh no you didn't Rainbow! You didn't just used THAT on me, you of all people!'.

"We just want to help you Sunset, we are your friends after all". 'Oh Fluttershy, sweet innocent Fluttershy, you want to help me? You? Who won't even dare to put a male and a female of your precious animals together for fear they'll get it on in front of you?'

"Seriously girls! I'm... Im... Everything... Is ok". Sunset involuntarily hugged her sides as her condition worsened, she felt stomach pain but she knew that it was something deeper and lower that actually bothered her. 'Why is it getting hotter, can someone open a fucking window already!?'.

Sunset stood up from where she was seating, she needed some privacy fast or the whole thing would blow in her face, or lower, as she tried to go out of the room Pinkie Pie jumped in front of her and used her lighter body to block her path.

"Just tell us already! We'll fix whatever problem you have and after I'll throw you another party that would nock your panties out!".
'Damn Pinkie, if you really were to see my panties right now you would leave them where they are!'.

Sunset didn't say anything, rather she just moved forward forcing Pinkie out of the way, her move carried out more force that she thought first and what Sunset saw and felt only as a light push end up been a shove sending Pinkie tumbling over Applejack who cried in surprise as Pinkie fell in her lap sending her drink and junk food all around.

All other 12 eyes in the room turned to her, well 11, Fluttershy had one hiding behind her hair out of fear, Sunset felt that her face was on fire, shame and embarrassment for once dominated her increasing lust, Sunset saw her hand, the one she used to push Pinkie out of her way, her friends were speechless but from their faces Sunset could almost tell their thoughts, if the 16 year old Sunset could be here, the one that was still the queen bee of CHS, the one everyone feared and cursed in silent she would be proud.

"I.. I think I'll sleep by myself in the living room". Sunset passed around and took her sleeping bag, no one tried to stop her, they saw what happen to Pinkie and they feared the same result or worse.

"Ah think ya should". Applejack was the only one that answer back, Sunset was surprised she didn't kick her out of the house completely but it could be just because it was too late to send her home.

After walking out of the room Sunset moved down stairs, her moves were clumsy and out of energy, most of the lights inside the Apple house were off but the moon give her enough light to see around, Sunset found the sofa in front of the Tv and left her bag in there, she didn't feel like sleeping at all and now that the shock of what happen was passing her mind detected another more pressing need to take care off, still, Sunset didn't want to walk back upstairs, she didn't feel like she deserved to even use the restroom, mindlessly she walked out of the house, her feet dragging, she walked through some of the roads passing the tool shack and the barn.

It was dark but the moon looked so bright that Sunset could still see a few feet in front of her, suddenly her eyes detected a small light in the distance, it was a small flicker of light but still visible for Sunset, she followed with her mind still numb from what just happened, ignoring the fact that a light in the middle of a farm in the night was to be avoided, that someone may attack her, that the light may be her imagination, all those facts were lost to her, only her sadness and the pressure of her lewd body existed in Sunset.

After a few couple of minutes Sunset finally lost the light she was following, only then her mind registered that she was lost in the middle of the apple orchard at nigh, panic started to bring back some form of thought, to further increase her anxiety, the moon was blocked by a passing cloud depriving her of the only other form of illumination.

She shrugged feeling a bit of cold, her situation bringing her close to tears when the small light reappeared, she hold her breath took a couple of hesitant steps in the direction of the little mysterious miracle, feeling her body reclaiming her need for relief Sunset moved like a horse been guided back to the road.

As she got closer to the source she was able to distinguish an old shack, it looked older that the rest of the rest of the constructions on Sweet Apple Acres and as Sunset got even closer the shack took the form of an old stable, Sunset stood in front of it with no idea of what to do, should she go inside and inspect the place? Wait outside for whomever was responsible for the light or try to return to the Apple house through the dark once again all why been driven crazy by her hormone infested body.

Her decision was take it from her by her own body when a wave of pleasure almost caused her to lose her footing, this alarmed her even further after noticing that the time between her reliefs were getting shorter, her body was also becoming more sensitive each time and her grasp on control was slipping away even faster.

Sunset gritted her teeth trying to fight back while moving inside the stables, once inside her mind was hazy already and some of the stuff inside passed unsuspected to her like the old but still used trunk in one corner of the stable were the was a small stool that had a dimming candle on it, the place wasn't abandoned despite the outside appearance, the wooden floor was almost free of dust, the air around it smell of apples and oil instead of damp.

Sunset moved slowly holding up to the wooden rail that separated the walkway from where the horses were to be kept, the old and faint smell of horses still lingered in the air making Sunset felt nostalgic and out of place at the same time. Sunset considered herself more human now that pony but she would never deny her true self.

Interrupting her self loathing Sunset's body send a wave of pleasure through her pelvis all the way up to her uterus, the sensation was stronger that everything Sunset experienced so far and she knew she couldn't hold it anymore, risking everything Sunset rested her back against the wall away from the trunk and the stool, with shaking hands she pulled down her shorts revealing light pink panties which were drenched already with her juices, she removed part of her top too letting free one of her breast, swollen and nipple fully erect, the flesh around the cup had a soft pink color already, Sunset remembered that her breasts have grown recently and had also became more sensible at the touch.

Holding her top up with her teeth Sunset used her left hand to massage the wet lips of her pussy as her right hand fondled her exposed breast with circular moves. 'What the hell am I doing?'.

The foreplay send ripples of pleasure through the 18 year old girl causing more juices out of her lower mouth, her knees felt weak and more that one Sunset had to restore her position before continuing her self satisfaction. 'I... I need... to stop this... but... it feels... good'.

Getting more aroused Sunset pulled down her panties completely as well as her top, now she was exposed completely and that drove her mind further away from reality. Her fingers now did their way inside her warm tunnel moving slowly to scratch the soft nethers of the girl, the other hand was busy providing attention to the other breast, as Sunset's mind was struck with wave after wave of pleasure she failed to heard the approaching footsteps that were getting closer. 'Hmmm... Hah!... Just... just a little more!'.

The girl felt release reaching its peak and a burst of liquid ran down her legs at the same time that she pinched one of nipples with more force that before, all the intensity that her body felt was translated to her voice in the form of a moan that cut the silence like a knife, Sunset left herself shaking and exhausted with an afterglow in her face and body.

It was in that moment when silence returned that the fall of an object drove all senses back in to the head of the girl, her eyes turning to the entrance where a young tall blonde man was paralysed with his mouth agape and his green eyes wide open.

"Bi-Big Mac?". 'Oh for the love of...!'.
