Chapter 1

Princess Celestia had ensured Twilight would be ready for all that becoming an alicorn princess would entail; all but one... vital... detail.

In Golden Oaks Library on the second floor just outside the librarian's private bathroom Spike paced nervously. Earlier he had been shocked out of bed when he heard Twilight scream and now she had locked herself into the lavatory.

"Twilight, you've been in there for hours! Are you sick?" Spike turned to Owlowiscious "Do alicorns get sick?" From within the bathroom he could hear Twilight start to answer him only to stop, gasp, and start to moan again. "Twilight you really don't sound good."

"Oh, she does sound pretty bad." Pinkie Pie chirped as she suddenly appeared directly behind Spike.

"Ah! Pinkie! How did you get here?"

"I walked silly, as soon as Rainbow told me what you told her I told the Cakes what she told me and they told me they could take care of the shop so I could leave to come help my friend."

"But where's everyone else?" Spike looked desperately at Pinkie Pie.

"Right behind me Spiky-wiky." Pinkie stepped to the side just as Rarity, AJ, Fluttershy and Rainbow Dash came up the stairs.

"Oh Spike, we came as soon as we heard Twilight wasn't well." The white mare trotted to the bathroom door "Twilight, darling, how are you feeling?"

"What are you all doing here!" Twilight nearly shouted from the other side of her bathroom door, a touch of panic in her voice.

"We came to help dear, why don't you open the door and we'll see if we can't make you feel any better."

"NO! Don't come in! I'm not coming out I can handle this!" Twilight shouted back.

"Twilight, please, we can't simply sit by while our friend isn't well." Rarity plead.

"It's too embarrassing I'm staying in here until I can fix it."

"Now Twilight it can't possibly be any worse than any of us have had to deal with and if it is we'll be right here-" Rarity was interrupted by Rainbow's exasperated groan.

"This is taking too long! I'm busting open that door!" Before anyone could react Rainbow threw herself at the door destroying the flimsy lock and running straight into Twilight. They both crashed through the shower curtain and into the tub. The two dazed ponies laid in the tub covered in a book themed shower curtain. RD recovered a bit faster than Twilight and grinned down at her purple friend.

"There, now what's- WHOA!" RD stopped mid sentence as she finally got a good look at her friend, the lilac alicorn now sported a massive 18 inch erection. Twilight's throbbing horse shaft pressed into Dash's chest as she stood, as if entranced, over her formerly female friend.

"What's 'whoa' Rainbow?" AJ asked as she stepped through the damaged doorway.

"Oh my gosh, Twilight's-" Twilight quickly grabbed her friends muzzle silencing her.

"PERFECTLY FINE" The Princess half laughed half shouted at the confused mares in the doorway while RD struggled to speak. "See?" Twilight wiggled her head free from the tangle of curtains that had ensnared the blue pegasus and herself in her bathtub and gave her best fake grin. A sudden wicked thought caught hold of Rainbow. She gently placed one hoof on Twilights stallionhood and slowly started to massage it. Twilight gasped, her eyes crossed and her face blushed furiously as Rainbow giggled gleefully at her friends predicament.
Lost in bliss, Twilight accidentally let go of Rainbow's face and tried to brace herself against the side of the bathtub, which opened enough distance between herself and Dash to allow Dashie to use her tongue.

"Uhm... Twilight? Dash?" Fluttershy peeked over AJ's shoulder to try and see what was occurring within the shelter of the restroom.

"Don't worry girls I think I got this." A roughly pegasus shaped mound said from the tub. Rainbow quickly returned to licking and kissing Twilight's enormous equine erection. Twilight, to her credit, remained about as composed as anyone could be expected to while having their shaft shamelessly loved by another. Her tongue lolled limply from her mouth, her eyes rolled back in her head, her breath coming in short desperate gasps. She could practically feel Dash grinning around her new penis.

"D... Dash. Don't... DON'T STOP DASH!" Twilight grabbed RD's head in her hooves and pulled the pegasus all the way until her nose touched Twilight's sheath and came hard into her friends throat. Dash's wings reflexively spread full eagle and threw the tattered shower curtain off the two exposing her actions and Twilight's secret to the rest of their friends. Rarity's eye twitched, Fluttershy gasped and covered her eyes, Pinkie Pie leaned in for a closer look, and AJ fainted. All Twilight could do was keep pumping her seed into her blue friend. About a minute passed before Dash finally pulled herself off her friends cock, licking her the taste of Twilight's cum from her lips.

"Twilight that was AWESOME! I've never had a pony who tasted so good. That had to be like a half gallon and look at you, you're still hard! I was excited when you were just my new flying buddy. Now I've got a new fuck buddy too! Could this day get any better?"

"Ooh, oh, can I try! I want to try! Please Twilight, please!" Pinkie had somehow appeared on the opposite side of the tub and gave Twilight her biggest puppy dog eyes. Rarity loudly cleared her throat.

"Girls, we came here to help Twilight. Not to do... that," she waved a hoof towards Dash, "to her. Twilight, do you know what exactly caused this?"

"Caused what? What's happened to Twilight!" Spike had finally pushed through the ponies crowding the door to get a look at Twilight. His concern quickly turned to confusion upon seeing Twilights latest addition. His pupils dilated and he raised a finger as if to say "Oh." before fainting right next to Applejack.

"Oh girls," Twilight spoke between husky breathes. "This exactly why I didn't want any of you to see me right now. I've tried everything I can think of to make this go away but it's not a curse or jinx, it's not poison joke, it's not a magical construct. I can't magic it away, This... pe-penis seems to be as much a part of me as my wings or horn." Twilight started to blush again. "When you showed up I was trying to... to..." Twilight made a stroking motion with one hoof.

"Relieve yourself." Rarity tactfully provided.

"Yes. I was hoping it would go away but by the time you arrived I'd already-" She made the stroking motion again imploring her friends to fill in the rest.

"Wow Twi" Rainbow patted her belly "and you still had-"

"Twice." The purple alicorn finished. Dashes jaw dropped. "And it's still just as hard as it was the first time, and it's so sensitive."

"Really?" Pinkie asked as she poked Twilights twitching cock. The purple pony moaned at the contact as a bead of pre formed on her erections broad equine head. Rainbow wasted no time licking the clear fluid off her friend. "Hey no fair Dashie, I want to try some too!"

"Hehe, sorry Pinks, you'll just have to be faster next time. Maybe you should try camping out for it." RD shrugged her shoulders at her curly haired friend. Pinkie Pie's eyes started to water as she made the saddest face she could, somehow outdoing her previous attempts with Twilight. "Pinkie I just... I didn't." Rainbow wasn't sure if she should be apologizing or making an excuse. Pinkie Pie's eyes seemed to grow larger as she pouted harder at the rainbow maned pegasus. "and the cider... ugh." Rainbow threw her hooves up "Fine." The pegasus climbed out of the tub to make room for the confection crazy earth pony to hop in.

"No not fine!" Rarity started to protest. "We need to help Twilight!"

"Maybe sex will help her." The pink pony had already replaced Dash in the tub. "What do you think Twi?"

"Sex... yeah." She spoke slowly as if in a daze while absent mindedly stroking her shaft "Haven't tried that yet."

"Sex it is!" Pinkie giggled before moving Twilights hooves to the wet, winking, hole just below her purple erection. "You take care of this." Pinkie softly spoke before lightly kissing her friends pleasure button. "And I'll handle the rest of you." Pinkie's eyes shone as though she had just been invited to an all you can eat cake and sweets buffet.

The excited pink pony licked her princess agonizingly slowly from root to tip. Her broad, soft tongue caressing the underside of Twilight's cock. Precum ran in rivulets down Twi's equine shaft as Pinkie kissed and licked around it's sensitive head, down to nibble at the sheath the slowly back to the top to suckle the delicious fluids Twi was leaking.

"Mhmm, my oven is preheated and it looks like your meat is properly basted Twili." Pinkie stood up and positioned herself over her formerly female friend's slicked shaft. "Ready to start baking?" Twilight barely murmured a response. "What?" Pinkie Pie asked as she brought her legs together over Twilight's 18 inch dick using the soft fur of her inner thighs to torment the alicorn. "I couldn't hear you?" Twilight had to focus all her self control on not magically throwing the insufferable pink tease against a wall and fuck her until she couldn't stand.

"Yes, I'm ready." Twilight's voice was only a bit above a whisper. Pinkie yawned, looking bored with the reluctant princess. Across the room Rainbow Dash could be heard barely containing her amusement as the party pony teased their friend. "Yes!" she shouted "Please Pinkie, I want you to fuck me!"

"Oh, well if that was all you wanted." She sank onto Twilights cock until the whole of it had disappeared into her. "All you had to do was say so." One of pinkie's hooves traced the slight bulging line of Twilight's shaft causing the alicorn to shudder and buck her hips into the pink one. Pinkie slowly rose back up Twilight's pole stopping long enough to brace herself with one hoof on the lip of the tub before she started bouncing in Twilight's lap.

"Pinkie," Twilight panted, a desperate look in her eye, "Slow down Pinkie. I can't take much more of this!" The purple alicorn could barely keep up with her energetic consort. Pinkie didn't seem to hear any of it, her eyes had rolled up staring blankly at the ceiling as her mouth hung open letting her tongue hanging out limply. The baker placed her hooves on Twilight's chest and screamed out her ecstasy cuming hard around Twilight's massive shaft. The feeling of Pinkie getting off pushed the Princess over the edge. Twilight magically grabbed Pinkie and pulled her down hard into her hips as she filled her friend. By the time Twi released her Pinkie looked as if she had been caught at one of the Apple Family get togethers and still she rode Twilight, though more slowly.

"Pinkie, that is no way to treat a uhm... lady. You can't just use somepony's penis like a it were a pogo stick." Rarity trotted to the side of the tub to help Pinkie. "Let me show you how to properly pleasure a stallion."

"Aaww Just when I was really getting started." A look of horror passed over Twilight's face. Rarity gave Pinkie a stern look and pointed towards the corner of the bathroom occupied by Dash. With a sigh the disappointed pink pony took a seat next to RD.

"How are you feeling Twilight?" Rarity levitated a glass of water over and offered it to her.

"Better, Rarity, though I'm still so..." Twilight waved her hoof at her erection "It's so much stronger even than being in estrus, I can barely think. Did you know Alicorns have heightened senses? I can smell how ready all of you are, practically taste it, and it's driving me crazy!"

"Well Twilight," AJ, having recovered thanks to Fluttershy's care, called from the door, "we'll see if we can't tame that desire o' yours."

"Indeed, ready for a lady to show you how it's done Twilight?" Rarity stepped into the tub before Twilight could respond. She stood above Twilight and flipped her mane. "I must say, I've been dying to get at that magnificent tool of yours since Rainbow blew your cover." She gave the head of Twilights cock a little lick savoring the mixed flavors of her friends like a fine wine. "Oh yes. This will do quite nicely."
Rarity slowly descended Twilight's tower taking her time as she worked it into her tight passage. Inch after inch slid into her as she got comfortable with Twilights belly bulging member. As Rarity hilted Twilight she paused to enjoy the heat of it inside her. Rarity could feel the beat of Twilights heart through her cock.

"Rarity, you're so-"

"Quiet dear, now is not the time for talking. Put your hooves on my hips darling. Good girl. Now let me show you how to please a stallion." Rarity began the slow climb back up Twilights shaft rolling her hips as she went. Pinkie had been a sprint, Rarity intended to make it a marathon. Rarity placed her hooves on Twilights stomach and ran them over her soft fur up to her chest as she came back down. Stretching every movement into a luxuriously slow dance.

"I... I'm going to-"

"Darling, didn't I tell you not to talk?" Rarity produced a black silk ribbon and tied it around the base of Twilight's erection. "I'll allow you to get off only after you've pleased me and you're going to have to work a lot harder than that if you want relief." Twilight's eyes crossed as her body tried to climax to no effect. She winced and groaned as her balls tried to empty their payload, tricked into overdrive by a simple silk ribbon. Finally Twilight understood and she started to buck her hips to match the pace Rarity had set.

The white mare moaned as Twilight thrust into her, filling her more completely than she had dared to hope. The flared head of Twilights shaft stretching her to her limit, the medial ring rubbing her clit as it passed in and out of her, and the heat of it inside her like a fire in her belly. It wasn't much longer before it all started to overwhelm Rarity and she felt her climax building.

"Fuck me Twilight! Fuck me harder! Yes, YES!" Rarity's mouth hung open and her eyes crossed in the most undignified display of bliss any of the other ponies had ever seen. The diamond flanked mare screamed out as she came soaking twilight's nethers with her feminine juices. A minute passed before she could collect herself and get off of Twilight, who had continued to pump her shaft into Rarity. Standing on two legs, Rarity pressed on of her rear hooves onto twilights still bound shaft. Rarity leaned gently forward until her muzzle was only an inch from both of Twilight's heads.

"Say, ahh." Was all the warning Twilight received before Rarity planted a light kiss on the head of her cock and untied the ribbon. Twilight barely had time to open her mouth before the climaxes she had been denied came rushing up to meet her. It was a torrent she could not hope to keep up with. When the flood finally died to a trickle she had coated her face, neck, and chest. Twilight had swallowed as much as she could but her body's production was far beyond anything she could have kept up with.

"Oh dear, seems I got carried away again. At least you're already in the bath." Rarity pouted at the mess she was partially responsible for creating. Rarity reached for the faucet.

"NO!" Everypony turned to Fluttershy who had leapt to her feet. "I mean... I'll clean you Twilight... If you'd like." The room remained awkwardly silent while Fluttershy poked at the ground. "I... I'd like to take care of you Twilight." Fluttershy trotted cautiously to the tub and hooked her hooves over the rim.

"Well... alright Fluttershy." Twilight was at a loss for what else to say.

"You made quite a mess." the yellow pegasus flew gracefully into the tub with Twilight after Rarity made her way to sit beside Pinkie Pie and Rainbow Dash. Fluttershy blushed but didn't hesitate to lick a little of the cum from Twilights cheek causing the princess to blush just as bright. Fluttershy moaned quietly as if she had just had taste of her favorite treat "Rainbow was right, you do taste really good Twilight." The alicorn laughed nervously as the pegasus licked her face clean.

"Don't worry, I'll take good care of you." Fluttershy gave Twilights ear a little nibble before moving down to her neck, kissing and licking up every drop along the way. The purple pony muttered something akin to 'mhm' as Fluttershy continued right along softly biting Twilight every so often. In less than a minute Twilight was leaking steadily from both sexes and Fluttershy had cleaned her entirely of her last release.

"Everypony has been so focused on the new parts of you no one has paid any attention to what you already had." She ignored the irony of tasting some of the pre running down Twilight's shaft as she spoke. "I've always admired you Twilight. You're so strong; but even the strongest ponies need someone to take care of them sometimes." Fluttershy moved her muzzle within an inch of Twilight's vagina and every warm breath caused the alicorn to twitch and squirm. Fluttershy simply admired her friends sex for a moment.

"I'll take care of you Twilight." The pegasus whispered just loud enough to keep the statement private. "Whenever you need me, I'll be there for you." Twilight could only pant in response, overwhelmed by the sexual nature of Fluttershy's attention. Fluttershy dove into her friend lapping at her labia and clitorous. Her tongue worked on Twilight in ways the purple pony had never imagined and seemed to reach deeper than it should have been able to.

The other ponies watched on as Twilight made noises that nopony would consider proper for royalty. AJ trotted across the bathroom to sit beside Rarity.

"Anypony seen Spike?" Not even Applejack appeared interested in the answer to her question. "She... Uh... Flutters do this a lot?"

"She's the best I've ever had the pleasure of." Rarity blushed as she watched Twilight squirm wondering if she looked the same while Fluttershy took care of her.

"Sometimes Flutters and I find our own little cloud and spend the whole day just having fun." Dash shivered and smiled as she recalled a few of her favorite moments.

"I go to her cottage on weekends for a little pet play." The other three ponies turned confused looks at Pinkie Pie. "What? Who in equestria would have more experience with pets than Fluttershy." The other ponies looked at each other not entirely certain if Pinkie meant the fetish or actually playing with animals.

"She has a point." RD Shrugged.

"So I'm the only pony who hasn't gotten a licking from Fluttershy?" Behind AJ Twilight cried out as Fluttershy brought her to yet another clitoral climax. Applejacks ears drooped, "That just ain't fair."

"No offense Applejack but you don't really seem like the kind of mare who would... appreciate, the attentions of another mare." Having finally found the will to look away from the purple and yellow passion play before her Rarity gave Applejack a discerning look.

"I like mares just as much as any of y'all... Except maybe fluttershy I suppose. You could have asked me."

"AJ I've tried flirting with you so many times I had to ask Twilight to help me keep count. It all just seems to go right over your head." Rainbow waved one of her wings above her own head to help visualize the point. "Even your brother picked up on it."

"What's that supposed to mean? Have you been flirting with my brother!?"

"What? No I- That's not what I-" RD sat bolt upright, suddenly on high alert.

"Not what I, what? Ain't Big Mac good enough for you? Wannabe wonderbolt can't be seen with an earth pony stud?" AJ cut Dash with a withering glare. Rarity and Pinkie pie watched the two bicker their heads following the speakers as a confused Dash desperately tried to backpedal out of the conversation.

"Now, wait just a minute Big Mac is a great lay an-" Dash covered her mouth with both wings. Pinkie Pie, Rarity and even, albeit for an entirely different reason, Twilight gasped.

"Flutter- Fluttershy I can't! It's too many!" Twilight shuddered her mouth moved as if she was trying to speak but couldn't focus long enough to do so. Fluttershy smiled up at Twilight between her hind legs.

"If you'd like Twilight, you can cum inside meEEEEEEEEEEE!" Fluttershy suddenly vanished, pulled outside the bathtub by AJ's lasso.

"Out of the way flutters. Y'all got me in a winkin' mad mood and I ain't gonna wait to blow off some steam." Applejack marched to the middle of the bathroom and presented her backside to Twilight "Get over here so I can make a stallion out of you."

"Ap... Applejack?" A confused look crossed Twilights face.

"Twilight, that wasn't a request." Applejack's flat expression spoke more plainly than her words. Twilight used her powerful wings to aid her out of the tub leaping gracelessly to answer AJ's order. She barely managed to keep her feet beneath her as she touched down behind Applejack. Rainbow Dash sighed and pressed a hoof into the bridge of her muzzle.

"That's more like it, now let's see if you can use that thing between your legs." Applejack wiggled her plot at the alicorn.

"Hopefully better than she can use her wings." RD said under her breath.

Twilight eagerly mounted her equally eager partner. She pressed the head of her erection against Applejack's cunt teasing her with the promise of penetration. The heat coming off the orange pony urged Twilight onward. She lubricated her cock with the liquid flowing from her friend's pussy and slowly pressed the head in. Applejack shuddered and for the first time in the entire night Twilight felt like she had some control of her new sex. With one quick thrust Twilight buried herself to the medial ring inside AJ.

"OH yeah! Let's get this rodeo rolling."

Twilight thrusted deeper and faster, her confidence growing with every stroke. Her partner, not one to let anypony else do all the work, started to buck her hips back to meet Twilight's passionate thrusts. Soon both ponies were moaning and fucking as if their lives depended on it. Twilight pounded Applejack relentlessly.

Applejack took it like a champ, years of working long hours on the orchard helping her keep up with the frantic fucking Twilight was giving her. AJ came twice as Twilight's cock seemed to find all her most sensitive spots with unerring accuracy over and over. Finally the head of Twilight's shaft began to flare driving AJ to new heights and buckling the powerful mare's forelegs.

Face down on the floor the orgasm that tore through AJ left the poor mare nearly insensate. The muscular walls of her already tight vagina contracted around Twilights maleness as if milking the massive tool. That was the final push needed to send Twilight crashing into her own orgasm flooding the orange pony with her seed rounding out the orange apple ponies belly. Their mixed juices poured onto the floor as Twilight unplugged AJ's passage.

Finally, after what had seemed like days to the desperate pony princess her equine penis softened and pulled back into the sheath between her legs. She would have danced for joy if she hadn't been worn out from all the exercise instead she simply sat down and savored the ability to think clearly again. Unfortunately this also allowed her to see what a mess they had made of the bathroom. The shower curtains had been torn and currently lay half inside the toilet. Several leaky ponies sat spread about the room and one wall was covered in Twilight's own sticky mess.

"Hehe, well Twilight, feeling better?" Pinkie Pie chirped from the other side of the room.

"You have no idea Pinkie. It felt like my brain was foggy. I'm just glad this thing has finally settled down." She pointed at what everyone knew she was talking about. "I was afraid it was never going to be satisfied."

"That would make running a country extremely difficult." A soft, familiar, voice spoke from the doorway. Every pony in the bathroom turned to the doorway, looks of horror etched across their faces as none other than Celestia stood looking over all of them. "Wouldn't you agree my little Princess." Celestia turned and walked into the bedroom her, the strength of her presence pulling the ponies along in her wake.

The mane six entered Twilights bedroom as one. Inside the Princess of the Sun calmly awaited them.

"C-Celestia!" Twilight started "Why are you here?"

"Spike sent me a letter about your condition and considering the personal nature of the problem I thought it may be best to see you myself."

"Wow..." Twilight shot Spike a glare that could cut steel. Twilight looked back at her mentor, laughing nervously. "Thank you Princess but, uhm... my friends have already..." the tiny alicorn poked the floor with her hoof, "taken care of me."

"I can see that." A coy smile spread across the princesses face. "Your friends should know though-" Between Celestia's legs a shaft that easily dwarfed Twilights spilled from it's sheath.

"That if they intended to take care of one princess-" Luna stepped up alongside her sister, a dark blue cock twitching to life beneath her.

"They will have to take care of us all." Princess Cadance finished, her own eager equipment already leaking.
Celestia smiled coolly at her student and licked her lips.
