Pinkie Pie stared at her nipples in sympathetic delight.

The poor things were freezing! The night air all around her was cold and windy, and she didn’t have nearly enough layers on to keep all the way warm, just her usual cute little white shirt. Sure, she had her light blue jacket on too, sitting snuggly wuggly over her shoulders, but it was open in front, so her ever-small airbags were feeling cold. And when her boobies got cold, her nipples got stiff, and when she was wearing a thin shirt like this one, her nipples pressed right on through it and it was so so neat-looking she barely even remembered to feel sorry for them!

Pinkie shifted her patootie over a few inches on top of the giant horse statue outside of Canterlot High, to make sure she wouldn’t fall off, and let her right hand trace silly circles around one of her pokey nipples. Her pampered pillow hummed in gratitude for even her hand’s protection against the nighttime chill, and Pinkie felt a smile creep across her face. She loved making her friends happy, but she had a special soft spot for making her boobs happy too! And the way it was humming and thrumming just then meant she was doing a great job. Each circle she traced around her nipple sent a chill through her whole body, but a happy chill, like when she brought lemonade for everybody but didn’t realize until they started drinking it just how much everybody really did love lemonade! When life gave you boobs, make lemonade? No, that didn’t sound quite right.

Oh gosh! There she was on top of the horse statue, doing all this happy-making, but her other funbag was being totally left out of the fun! And that one’s nipple was just as hard and pointy as the other one, maybe even moreso. Sometimes people like Rarity had tried to get her to wear bras more often, but bras were just another kind of constraint, and Pinkie hated being constrained! Or at least she didn’t like it very much. She didn’t like the idea of hating things. It was so much better just to like things, and she liked her boobs, and she liked feeling good, and rubbing her boobs made her feel good, so on with the show! Another quick shift to make sure she really really wasn’t in any danger of falling, because gee the statue’s back was awfully slippery this time of night, and Pinkie grabbed her other boob as well, massaging them up and down through her thin shirt.

It felt so good! If Pinkie Pie was a sensitive girl, then her itty bitty titties had to be the most sensitive part of her. Carelessly, giving more attention to the feelings than to the movements, Pinkie rolled her boobs this way and that, the fleshy mounds easily small enough to fit all in her hands at once. Her nipples were so hard, and the rest of her boobs were so soft, and it just felt so amazing sitting there rubbing them around and around, back and forth, each motion sending another wave of bliss running through her. Even her tiny Pinkie toes were tingling, all wrapped up in her big blue boots! She kneaded her tit flesh, everything feeling happy and almost-warm and bouncy and soft and hard and… ooh, and wet!

Well, that wasn’t right. If she started getting all wet right there, she’d just ruin her panties, and Rarity’d asked so many awkward questions last time she’d gone in to get a new pair. There was only one thing to be done. Pinkie rolled up her skirt, smiling merrily at the balloons sewn onto it, reached down, and yanked her panties down her legs. No, she might still drip on them there… better to go all the way. Her bare butt felt really freezing against the statue, but she had panties to protect! Reaching up one leg, then the other, Pinkie pulled her panties away and threw them to the grass below. Now she could breathe easily. Or… rapidly. Teeheehee!

After a moment of anguished decision-making, Pinkie Pie left her little landmines to her right hand alone, as her left hand plunged downward to slide into her good old love hole. Pinkie slipped her fingers inside one by one, probing and stroking the inner flaps of her pussy, and sighed contentedly as her scent wafted up to her hungry nostrils. Strawberries! Her favorite. Not that smelling like strawberries was anything new, of course, but she loved it every time, which struck her as the best possible reaction you could possibly have to whenever you started to masturbate. Happiness!

Pinkie Pie’s little clitty was still only damp, but she was sure that would change soon enough. She giggled at her massive pink pubic curls tickling against her searching hand. They were just like a tiny version of the curls on top of her head! Ooh, but that wasn’t what she was focusing on, not when there was a dampening pussy to attend to. Pinkie dug her fingers in a little farther, marveling at how warm she felt inside even against the night’s chill. Maybe… maybe she could take some of that warmth and put it on the rest of her body? It was worth a try!

Her shirt was really just getting in the way by then, so she pulled it up to her neck. Much better! The pussy hand, now satisfactorily dripping with yummy love juices, was pulled up and brought back to her newly-uncovered chest. The liquid made everything much smoother, and soon she could give herself a proper boob massage without any of those pesky concepts like ‘friction’ getting in her way. This was the life! Again and again she reached down within herself, feeling and exploring her heavenly warm wetness, and then brought her hand back up to lather up her beloved little boobies. Her nipples practically sung out in delight every time she tweaked them, and not for the first time she wished her silicone sandcastles were a bit bigger so she could suck one of her own nipples in her mouth, just once, just to see what it’d be like…

“Pinkie Pie?”

Pinkie shrieked, slipped, righted herself, slipped again, and only kept from falling off by hurriedly throwing her arms around the statue’s wide neck. Her shirt fluttered back down over her wet chest, which she guessed was probably for the best if she had company. “Yeah?” she asked eventually. “I’m Pinkie Pie, yup! Hi! Who’s there?” Her voice sounded a wee bit ragged to her, punctuated by hard excited breaths, but she hoped whoever was down there wouldn’t notice.

“It’s me, Applejack.” Pinkie Pie blinked and looked down, and sure enough, there was that unmistakable brown hat, even in the darkness. “You sittin’ on top of the statue, then?”

“Oh, Applejack, teehee, yep!” She smiled, though really she doubted Applejack could see her face. But smiling was never a bad idea. “You know me, Applejack! Always getting up to craaaaaazy hijinx!”

“Well, sure, but on the school statue? Are… hang on.” Applejack sniffed loudly, and Pinkie braced herself for the upcoming conversation. “Are y’all masturbatin’ up there?”

“Uh…….. wow, what makes you think that, Applejack?”

“Well, you keep sayin’ my name, like you’re nervous about something. You smell of sex and… strawberries, turns out? Huh. Oh, and I’m pretty sure these are your panties down here, and it looks like your skirt’s hiked up awfully high.”

Pinkie Pie permitted herself a modest blush. Her panties were a private affair! Getting caught masturbating—by Applejack!—was one thing, but it was just bad form to leave her underwear lying out like that. “You caught me!” she cried, not sure whether she ought to sound amused or embarrassed. “Please don’t tell anybody, okay? I bet Principal Celestia would be totally cross if she found out I was messing up her nifty statue, and Rarity would be just horrified, and, and, hmm…”

“Hey, hold your horses, girlfriend.” Applejack sounded… well, not amused, exactly, but certainly not angry. Not angry was good! “I’m not reporting you to no authorities, not our friends either. Just… finish up, all right, and I’ll come back in a few minutes and we can pretend this never happened.”

“Thanks, Applejack! You’re the bestest!”

“Aw, don’t you go saying that.” That time Pinkie definitely heard amusement. Hooray! She lived to amuse, after all. “Make it fast, though… it’s cold out here.”

Pinkie listened to the sound of Applejack’s footsteps retreating into the darkness, and breathed out in relief. That had been close! Fortunately Applejack was so super nice, and probably the best girl to get caught out by. It’d absolutely scandalize Rarity, and Fluttershy would have been terrified, and Pinkie would have had to wear full-body outfits with lots and lots of layers for weeks or something just to get to talk to her again. Rainbow Dash… well, Dashie’d never seemed to have much time for sex and stuff, since she had soccer balls to worry about instead. But she probably had to think about her body a lot for training, so maybe she knew a lot about masturbating? Somehow the conversation had never come up. Dashie was one for the mystery column, then.

Oh, and what about their newest friend, funny sunny Sunset Shimmer? She’d used to be a villainess, after all, and everybody knew that villainesses were all about using their sexuality to get people to do what they wanted! But Sunset had mostly just used Snips and Snails for that instead, and they weren’t in the least bit sexual or even sexy. And yet Sunset herself was pretty sexy, Pinkie thought, with that two-toned hair she kind of wanted to get lost in, and of course her amazing tits! Pinkie reached back down to her cold and lonely pussy, which had dried up a bit while she’d been talking to Applejack, and started to rub it up and down just at the thought. Pinkie’s own tiny lumps were little more than ‘boobies’ at her most generous, but ‘tits’ were really the only word for Sunset’s awesome bod. Okay, maybe ‘cans’ would work too, since you’d be able to smuggle so many soda cans in them given the chance.

Pinkie barely noticed that she’d once again clasped her right chest cannon in her other hand, cupping and uncapping it to feel the soft wet skin sliding against her greedy fingers. She was too caught up in thinking about Sunset. “Pinkie Pie!” she’d say, with that wild look in her eyes. She’d lean forwards, jacket opening around her, and her shirt would fall away just enough to give Pinkie a teasing glimpse of those beautiful big balls of hers. Unconsciously, her pussy hand sped up a little. “Pinkie Pie,” Sunset would say, “were you… masturbating? On school property?!”

“Um, yep!” Pinkie Pie would say. Or, hmm, imaginary Pinkie Pie, anyway. “Are you going to punish me?” imaginary Pinkie Pie would ask.

“Hmm, no,” imaginary Sunset would answer. “Friends do not punish each other. You have taught me that friends must support each other and do things together!”

“Things? You mean, like… masturbating?” Real Pinkie Pie gasped at the thought, even though it was her own, and kneaded her slick boob furiously. There was a satisfying plinking sound as her pussy dripped out onto the statue.

Imaginary Sunset would laugh. “No, friends don’t go that far that fast! But I don’t think there’s anything wrong with a topless party!” With that, imaginary Sunset reached down and whipped off her shirt in one fluid motion that left imaginary Pinkie Pie staring wordlessly at those incredible tits, so round and full of life, and her long nipples, one red, one yellow, just like the rest of her…

“Will you look at that!” said imaginary Applejack. “Pinkie Pie, speechless? I never thought I’d see the day!” Imaginary Applejack had her own shirt off by then, and real Pinkie Pie moaned happily at the sight of Applejack’s own honkers. They weren’t nearly so big as Sunset’s, nor as round, but they hung down against her chest just right, and suddenly Pinkie wanted nothing more but to count every one of those freckles, maybe with her tongue, maybe all night long.

“Breast party?” asked imaginary Rainbow Dash. “More like best party!” She flexed her wrists and tore her shirt right off, everyone cheering as her flat chest came into view, her barely-there mounds practically dwarfed by her muscles below. But her perky nipples were a brilliant pink that stood out hotly against her blue skin, and her areolas were so wide that Pinkie couldn’t really complain.

Real Pinkie Pie moaned once more and shifted to spread her legs as far apart as she could get them without danger of falling off. Her hand darting in and out of her soaked pussy was getting quite frantic, and she flicked her joy button, pretending it was one of Rainbow Dash’s adorable nipples. Imaginary Rarity had to go next, and she put up some protest, but soon she too was stripped to the waist and her boobs were perfectly shaped, not too big, not too small, but flawless in every way and Pinkie Pie could feel herself getting so close. Her nipples were probably diamond-shaped, ooh, yes, that felt so good!

Only Fluttershy was left, and Pinkie Pie panted as she waited for her imagination to reveal that most treasured of treasures. Fluttershy was the only girl at school with melons even bigger than Sunset’s, and Pinkie had dreamt fervently of them ever she’d first met Fluttershy on their first day. They were so magnificently huge behind that super-short white shirt of hers, and occasional glimpses of her nipples poking through the fabric suggested that maybe she didn’t bother with a bra either. Pinkie melted a little at the very thought. By all rights Fluttershy ought to have been as shy about her chest as about everything else, but Pinkie was sure there had been times when she had seemed to go out of her way to draw attention to it, and there was always a little smugness mixed in with the terror whenever she caught Pinkie, or many of the other students, staring...

“Well,” imaginary Fluttershy said, “I guess it’s okay if, um, all of you are, um, doing, um, it.” Imaginary Fluttershy said ‘um’ a whole lot. Blushing hotly, she pulled her tiny shirt up, up, and away, and those beautiful, amazing, spectacular knockers of hers fell into view, and real Pinkie Pie cried out as her much-stimulated pussy gushed forth, girl juice showering over her hand and streaming all along the statue and down to the grass below. Pinkie’s sturdy body rocked itself again and again, and suddenly she felt herself slipping, this time for real, sliding half-naked down her own juices and into the darkness. She cried out again, this time from pain, as she landed on the ground, and then lay there breathlessly, blissfully, one hand clutched against her sex-slicked snake eyes, the other one pressed flat against the grass as her gently pulsing pussy slowly drained itself. Her personal scent of sex and strawberries surrounded her, and besides the cold, which was only barely registering at that point, she felt utterly at peace with the world.

“Aw, come on, Pinkie,” said Applejack a few minutes later. She was covering her face with one hand and just sounded exasperated. “You couldn’t clean yourself up afterwards?”

Pinkie scrambled up to her feet, a little shaky, and hurriedly pulled her shirt and skirt back down into place. Her skin tingled at the feeling of the fabric pressing back against it, and her boobs gave off an almost inquisitive hum, but there was no time for that. “Sorry, Applejack!” she said. “Could you pass me my panties?”

Applejack walked over to her discarded undergarments and picked them up slowly. Pinkie heard her sigh in relief, presumably at discovering them to be still dry. “Here you go,” she said. “Although if you’re still drippin’ down there, you’ll just get’em wet.”

“Oh, you’re right!” Pinkie beamed at her gratefully; Applejack could be so smart sometimes. Whistling, she pulled her skirt up a few inches and industriously scrubbed around her clit with one hand, flicking away or soaking up all the moisture she could find. She still felt damp, but probably not in a drippy way, and that was all that was important. “All done!”

Applejack stared at her. “Did you just… clean yourself up with your hand?”

“Yep!” Pinkie held out her hand for inspection. “Want to taste? I’m delicious!”

“Uh… no, I’ll take your word for it, thanks.” Applejack carefully passed Pinkie’s panties over and gulped. “Remind me never to shake your hand again, got it?”

“Got it!” Pinkie had a vague sense that things between her and Applejack might be a bit awkward for a while, but she was still too caught up in the haze of her past orgasm to mind. Just the idea of so many wonderful boobies all around her, especially Fluttershy’s… no, no, she couldn’t start thinking about that again, not with her panties on and Applejack right in front of her. “Sooooooo what are you doing out here this time of night?” she asked instead. She’d just have to think about other stuff, that was all.

“You know, I’m not rightly sure.” Applejack still sounded wary, but whether from the question or from the thought of tasting Pinkie Pie’s strawberry sex sauce, Pinkie couldn’t tell. “I just got this… thought in my head, all of a sudden, telling me I needed to come here. To this statue, I mean, not just the school.”

“Oh, no way!” Pinkie hopped up and down. “Me too! That’s totally why I’m here too! There was this surprise voice in my head, well, not really a voice voice, but an idea, and I knew I had to come to this statue and see what was going on!”

Applejack stroked her chin absently, looking up at the statue of the white horse rearing atop its large rectangular pedestal. “And did you see anything? I reckon there must have been something or other to get such a, ah, reaction out of you…”

“Nope! Nothing but darkness and cold and silence!”

“Hey, guys!”

The air around them shifted a little as Rainbow Dash ran up, wearing her usual outfit, with her hair streaming behind her as she came. She skidded to a halt between them, breathed out for a second while her hands rested on her knees, then looked up at them both with her daredevil smile. “Am I late?”

“Late?” Pinkie tilted her head to the right. “Late to what? I mean, yep, it’s pretty late at night, if that’s what you mean!”

“No, like, I got this weird urging thing in my head!” said Rainbow Dash. “I knew I had to come right here, and then obviously you girls got the same thing, right? Or were the others already here, and I’m late for the whole urgy party thing?”

Applejack shrugged. “Nobody’s late here that I can see, sugarcube. Me and Pinkie are just as in the dark about this as you are.”

“Huh, that’s weird!” Rainbow Dash stretched languidly for a few seconds before stopping as her face crinkled up in puzzlement. “Hey, do either of you guys smell strawberries?”

Applejack started coughing, but immediately waved off Pinkie’s attempts to hold her and help her out. Oh, right, Pinkie guessed she still had her cum all over her hands, didn’t she? She sucked on a couple of her fingers experimentally. Huh, Applejack didn’t know what she was missing out on. She started to wonder what Applejack herself tasted like… apples, probably? Then would Rainbow Dash taste like skittles? She really didn’t have any idea how this kind of thing worked on a larger scale.

Sunset, of course, would need to have two separate flavors, to go with her whole Two-Face motify thing. Maybe lemon, because she’d sure been pretty sour before getting hit by that magical friendship beam? And then she’d also need to be, say, chili pepper-flavored, to go with her fiery side. But peppers and lemons sounded like a pretty icky combination, even to Pinkie Pie. Hmm. “Hey Rainbow Dash,” she said absently, “what would you guess Sunset Shimmer tastes like?”

“How do I… taste?”

Pinkie Pie blinked—that voice hadn’t sounded like Rainbow Dash’s at all—and looked up. Walking along the grass from the direction of town were Rarity, Sunset Shimmer, and Fluttershy all together. Pinkie gulped and made a desperate effort to focus on their faces, and fortunately Sunset was making that easy, with her black jacket zipped up in front against the cold. But… oh, Principal Celestia forgive her, but Fluttershy was just wearing that tiny, tiny white shirt, and her skyscraper nipples couldn’t have been more obvious if she’d been wearing not a stitch above her waistline. It would have taken the willpower of a saint not to stare at her. Pinkie’s mouth went dry in an instant, all its wetness needed down below as she creamed herself completely and ruined all her hard work at keeping her panties clean before.

Now quite embarrassed, Pinkie managed to look up just in time to catch Fluttershy watching her closely. But there was no anger in her expression, only… kindness? Understanding? If nothing else, she made no effort to hide her clearly chilly ta-tas from Pinkie or anybody else, even standing a little straighter as if to thrust them forwards. Pinkie Pie breathed a silent prayer of thanks to whatever it was she was supposed to pray to, and tried to pay attention to the conversation, her gaze still flicking back to Fluttershy’s awesome assets every few seconds.

“No idea,” Applejack was saying. “Us three came here independently, but I guess we all got this weird urge in our heads, telling us this was where we had to be. Couldn’t tell you why.”

“I should think ‘impulse’ would be the better word, darling,” said Rarity. Of them all, she was dressed most appropriately for the night, with a large stylish blue sweater over her purple skirt.

“And the ‘why’ is obvious, peon!” said Sunset, and then coughed. “Uh… friend. I meant to call you a friend. Sorry, old habits die hard.”

Grinning, Applejack tried to catch Pinkie’s eye, but both of Pinkie’s eyes were stuck looking elsewhere. She blanched and walked a few steps over toward Rainbow Dash, who had gone back to stretching and didn’t seem to be paying much attention to the conversation at all. “No problem,” said Applejack. “But you’ve got a theory why we all felt this need to meet up here?”

“Of course, fool! …of a friend. Foolish friend. Friend, whom I call foolish as a form of endearment! Ha ha!” Sunset tilted her head back in laughter but snapped it back down again after a couple seconds. “What I mean is… clearly this is about the magic mirror.”

Rarity frowned. “You mean the portal to… that other world? Equestria? Well, yes, I suppose this is where it was when Twilight left us, isn’t it?”

“But, um…” Fluttershy visibly shrank when Sunset turned to stare at her, though she didn’t shrink where it really mattered. “Um, didn’t that portal only open every, well, thirty moons? And it’s only been, what, four moons since then? At most?”

Sunset nodded and began to pace back and forth, hands clasped behind her back as her eyes burned with a constant intensity. Applejack watched her skeptically, and Rarity took the opportunity to brush her hair with a brush she’d apparently stored in her sweater. “Yes, four moons,” said Sunset after several complete pacings. “But four moons with Twilight Sparkle. Twilight Sparkle is very clever and very powerful, you see. Perhaps in that time, she found a way to send a message to us through the mirror!”

Fluttershy raised one hand. Her shirt was pulled slightly upward by the movement, stretching deliciously over her enormous endowments, and Pinkie Pie could feel drops of herself trickling down the inside of her left leg. “I think Fluttershy has an idea,” she said, throat still dry.

“Oh, um, more of a question, really.” Fluttershy blushed. “I mean… all any of us knew to do was come here, right? That doesn’t feel like much of a message to me… sorry…”

“No, you’re right, you’re right!” Sunset threw her arms up in the air, hands clenched into fists, and stood there dramatically as if taunting the sky itself. “It is a pointless message for Twilight to send! Do you people get such sensations often, with your non-pony bodies? Mental suggestions like this one?” There was a general chorus of no. “Hmm. Second question… does anyone else have a headache right now?”

“Oh, I do!’ said Rarity. “It’s, ow, very curious! It wasn’t here just a minute ago, but now, ow, my head is absolutely splitting, and…”

A lots of things happened all at once.

Sunset and Rarity screamed as horns, tannish-orange and white respectively, burst from their foreheads.

Pinkie’s boobs started to tingle all over.

Large blue wings sprouted from Rainbow Dash’s back, though her jacket managed to keep her torso covered.

Yellow wings grew out of Fluttershy, and her shirt was ripped to shreds and fell to the ground.

Pinkie utterly ruined her panties, swore eternal devotion to Fluttershy’s beautiful, bounteous bosom, and resolved that if she did not find a way into her friend’s skirt before the semester was over then her life would be a failure.

Twilight Sparkle, outfitted with both wings and a horn, stepped out of the statue’s pedestal and said “oh, good, it worked!”
