Chapter 1: Presenting

Breezing through the sky on this fine, summer afternoon in Ponyville is none other than Derpy Hooves. The grey pegasus had taken to flying like a child takes to ice cream, having learned at a younger age than most pegasi. However, even to this day, the currently beaming mare often accidentally shows off her rather clumsy side. The breeze gently flowing through her wings as she makes her way toward one of her favorite stops in Ponyville brings a great smile to the cross-eyed mare’s face.

Looking down at the Everfree Forest below, Derpy flies carefully around it before landing right on the bridge leading from the edge of Ponyville to Fluttershy’s cottage. As her wings fold gently at her sides, she smiles and eyes her hefty mailbag before looking straight ahead for any sign of the mail’s recipient.

Just a few yards away, the pleasant and quiet caretaker is tossing out birdseed in an effort to feed her array of chickens and roosters gathered outside their coop. Upon seeing her shy pegasus friend, Derpy trots up behind her and calls her attention in her naturally cheerful voice.

“Hi Fluttershy!”

The loud voice coming from behind her causes Fluttershy to nearly jump out of her skin as she leaps into the air and accidentally spills the bird seed in her hooves all over the soft grass. The chickens swarm around it, pecking as much as they can while the pink-maned pegasus now hovering in mid-air tries to regain her balance. Finding Derpy still on the ground nearby seems to calm her nerves, knowing such an innocent pony could never harm her.

“Oh, hello Derpy! How are you today?”

Her soft voice responds as she glides back down to the ground and lands on the secure footing below. Derpy’s cross-eyed gaze hides itself for a brief moment as she closes her eyes in joy, proud to bring another pony her mail as she announces her purpose for arriving.

“I brought you a letter! It’s my first week on the job as a mailmare, and I’m super good at it!”

“That’s great, Derpy! I’m happy for you!”

Fluttershy’s gentle smile crosses her face as she watches the more than eager mailmare clumsily reach back into her mailbag to fetch the aforementioned letter. After only a second or two of rustling around the various papers and packages inside, Derpy makes a satisfied squeal of joy and grips the piece of mail between her teeth before whipping her neck around.

Her grip is apparently not enough to hold the flimsy paper, as the letter flies past Fluttershy and into a nearby bush as Derpy happily chimes up with her eyes closed.

“Here it is!... Huh?”

Derpy opens her eyes to find the letter previously between her teeth now completely gone, not knowing where it had gone and only finding a slightly confused Fluttershy in front of her. In truth, the mare had narrowly avoided a paper cut across her cheek with how fast that letter had flown right past her, but decided not to say anything, instead looking back at the bush that the letter was now stuck in.

Derpy pouts, her eyes still crossed as she flares out her wings in mild annoyance.

“Aww, did I drop it over there? I’m sorry, Fluttershy.”

The gray pegasus mare trots merrily over to the bush and ends up looking around for a few seconds. Rather unceremoniously, she drops her head into the bush, surprising Fluttershy with her rather direct approach before calling out as if trying to find a lost child.

“Hello? Little letter! Are you in here?”

Fluttershy’s gaze focuses on Derpy looking inside the bush, her eyes naturally attracted to the figure she awaits news from before she finds something far more attractive in plain sight ahead of her. Derpy’s impressive rear end is all there is to see now, the bubbles on her cutie mark making the perfect target for a gaze that has suddenly turned far more intrigued and attentive.

Those flanks and wide hips look as if they have been chiseled by the most skilled sculptor in all of Equestria. That shapely behind is such a perfect sight, she can’t think of anything else to see at the moment, her nearby chickens becoming as lost as the rest of the outside world. Yet, all the while, Fluttershy tries to think, to wonder why she wishes to get closer to another mare’s “plot.”

Words cannot describe the rush of heat and desire flooding her body as she stares forward, taking a light step toward the mailmare out of sheer necessity. Her eyes narrow and her face flushes beet red as her dazed expression becomes quite apparent to the nearby animals. The chickens are merely too occupied with filling their bellies to question their caretaker’s strange behavior.

The shy pegasus finally arrives directly behind the mare perusing the bush near her home for a mere letter of all things. She’s in such a vulnerable position, but that glorious rump of hers seems to beg for attention from anypony who is fortunate enough to lay eyes on it. Fluttershy can’t seem to form coherent thoughts as bits and pieces of these strange desires fill her head.

(“Look... Closer... Touch... Bubbles...”)

Her hooves seem to have a mind of their own as her foreleg reaches forward and, as gently as ever, Fluttershy’s hoof presses into the incredibly soft, plush rump in front of her, eliciting a slight squeal from the mare in front of her.

“Aha! Here it is!”

Derpy pulls her head out from the bush and whips around to present the letter to Fluttershy, her expression showing mere blissful ignorance to Fluttershy’s attraction to her remarkable behind. In her mane lies a few twigs and leaves, showing just how disheveled she became by digging through a bush, but she doesn't seem too bothered by the natural accessories. Staring forward at the mare’s proud grin, however, Fluttershy’s dazed expression seems to fade, leaving her confused and unaware of what had just transpired.

She stands closer than she did when she recalls, but seems to shake it off before grabbing the letter between her teeth and mumbling.

“Uhm... Derpy?”

“Yes?”

Derpy’s shimmering golden eyes reflect her innocence, her tongue sticking out the side of her mouth in a naive smile. Fluttershy considers the mare in front of her to be almost childlike, akin to her friend Pinkie Pie, but she can’t quite put her hoof on what had her so enraptured only a few moments ago. Instead of trying to figure it out, she dismisses the matter with a nervous smile of her own before answering.

“N- Nothing. Thanks for the letter, Derpy.”

“Oh! You’re welcome! I’ll see you later, Fluttershy!”

Derpy’s wings flap a few times before she jumps off the ground and ascends into the clear sky above Fluttershy’s cottage, heading towards Cloudsdale to continue on her next set of deliveries. Fluttershy merely waves a hoof in farewell as an unsure grimace washes over her. Taking a moment to look down at the chickens gathered nearby, the pink maned pegasus can’t help but think to herself.

“What just happened?”

In the rather large cloud city hanging in the sky, one particularly lazy stallion takes a few steps outside his comfy home with a look of sheer anticipation on his face. His dark coat and contrasting cyan mane styled into a mohawk do little to downplay the excited grin he wears. Trotting a few feet away to his mailbox, it’s clear that the pegasus known as Thunderlane is more eager for his mail than other ponies. Considering that most ponies would wait until later in the day to check their mail, the package he is awaiting must surely be important.

“Come on, PlayPony magazine...”

The stallion mutters under his breath as he reaches for the lid and closes his eyes in suspense. Gritting his teeth, he opens the lid with his hoof and peers inside with a wide smile on his face, only to find nothing inside. Immediately slumping at this result, Thunderlane shuts the lid to his mailbox and lies on the comfy cloud supporting the weight above it, feeling impatient after having waited so long.

“Damn it. This thing is taking forever.”

“Thunderlane! Special delivery!”

Upon hearing his name being called, Thunderlane’s ears perk up before his gaze seeks the source of the lilting voice. The one and only Derpy Hooves flies towards him slowly, taking her time to ensure she is being careful with her mail.

A half-smile forms on his face as the mare approaches and touches down in front of him. Feeling obligated to reply, Thunderlane remarks in a somewhat defeated tone.

“Hey there, Derpy. What’s with the bag?”

The stallion refers to Derpy Hooves’ mailbag full of letters and small packages made for easier delivery. The mailmare still puts on a confused face and looks to her side at the mailbag hanging over her by a loose strap. Realizing what he’s talking about, she turns back to him and answers while wearing a gleeful smile.

“That’s my mailbag! I’m a full-fledged mailmare now!”

Lifting her hoof and striking a pose, Derpy sticks out her tongue and winks at Thunderlane, her playfulness managing to exaggerate the joy she has at having what other ponies would consider a mundane and dull job. Thunderlane still chuckles however, going along with her even though, inside, he is genuinely surprised a mare like her has gotten a job already. He’s still at home living with his parents and his little brother after all.

As Thunderlane lets out a dismissive cough to ignore that thought, Derpy quickly adds on to her previous statement with a much more interesting piece of news.

“Aaaaaaaand I have a package for you!”

Thunderlane quickly picks himself up off the surface of the cloud and practically jumps into the air as his wings flare out in giddy expectation. Looking at Derpy with a greedy shade of dark gold irises, the stallion impatiently pesters her for the promised delivery.

“Great! Aww, Derpy, I knew I could count on you! So where is it? Is it in the bag?”

“Oooh! I think so! Let me check!”

Derpy matches his excitement with a happy smile of her own before gently resting the mailbag onto the ground beside her and turning to lean down and search through it. All the while, she makes happy humming sounds as she digs through the sack with her hooves to find what she’s looking for. Behind her, Thunderlane stares at rapt attention, his eyes drawn to the bag in front of him before something rather large obscures his view and causes him to lose focus.

His eyes seem to narrow as the plump globes in front of him demand attention from the stallion behind them. Thunderlane’s greedy eyes shift toward the luscious behind of the mailmare, bent over with her flanks raised high and her tail swishing playfully. A blush forms on his face as he finds himself unable to look away, embarrassed of the situation as he may be.

This is no ordinary plot. To Thunderlane, it might as well be the sexiest plot he has ever seen in his life. That amazingly round shape and pillowy soft flanks are enough to get his blood surging to his member to draw it out of its sheath. Of course, with only Derpy’s seductive rear end on his mind, it makes perfect sense that Thunderlane should get hard and want to desire her.

Gulping nervously, Thunderlane manages to question himself in a light whisper as his eyes follow that shaking plot from side to side.

“What the hell is wrong with me? She’s just a cute mare, right?... Right?”

(“Sweet Celestia she’s hot... I don’t know what I’m thinking but... I need that body, I have to fuck those sexy flanks!”)

As if following the sudden desire burning within him, Thunderlane moves forward and places both his hooves on the mare’s plush bottom, briefly squishing them together to see just how amazing they are to feel as well. Derpy doesn’t seem to notice this, however, only letting out a disappointed groan as she stops peering through the bag and turns to look back at Thunderlane with an apologetic sadness shining in her eyes.

“Aww, I can’t find your package in here! I must have dropped it on the way... Darn it, that’s the third time today!”

Derpy whines in a rather cute manner, her scrunched face still visible in the corner of Thunderlane’s vision. However, no matter how cute the mare in front of him is, he has his sights set on something he considers far sexier. With his hooves pressing into Derpy’s plot, Thunderlane leans forward until the tip of his now incredibly stiff stallionhood bobs just inches away from her marehood. In a dazed voice, the mesmerized stallion utters a cheesy remark in response to Derpy’s worries.

“It’s okay, Derpy. I know just how you can make it up to me. See, I have my own package that needs to be delivered~”

“... I don’t get it.”

Derpy replies, a confused expression washing over her as Thunderlane tries (and fails) to imply naughtiness to the relatively naive mare. Thunderlane seems to ignore her, however, now getting close to mounting her as his hot and throbbing member presses against her marehood and begins to smear his precum along it. Thunderlane can’t help but shudder under the pleasure coursing through him as her flanks seem so eager to welcome him inside her.

“Nnh, Derpy... Just let me ride those flanks of yours...”

“Ride? Oh, I love rides!”

As if suddenly remembering the childlike wonder of having her first piggyback ride, Derpy backs up and rears up so her forelegs dangle in the air happily, exclaiming aloud.

“Giddy-up!”

The movement throws Thunderlane off balance and he falls backward onto the soft cloud they stand on before Derpy soon follows suit, her heavy body landing atop him with a thud. Before Thunderlane can tell her to get off and stop from crushing his waist, he feels a warm, soft sensation wrap around his hardened cock. Opening his eyes, he finds both sides of his stallionhood clenched by the mailmare’s firm buttocks.

An overwhelming sense of comfort and security from being lodged between Derpy’s flanks overtakes Thunderlane and leaves him practically drooling as Derpy herself feels something slightly off about this position she has found herself in.

“Hmm? Something’s poking me... Oh well! Wee!”

Derpy happily proclaims as she begins to quickly bounce up and down on Thunderlane’s waist, forcing his member to slide between her flanks in such a playful yet naughty fashion. The stallion suffering such pleasurable torture merely stares down at her flanks and thrusts his hips upward to aid in her bouncing, loving the feeling of this mare’s amazing plot.

By now, he has completely forgotten about his package, surrendering completely and totally to Derpy’s rear end. There’s just something about it that makes him want to do such naughty things to her, regardless of the fact that he has never found himself attracted to her . How has he not seen it ? Derpy’s ass is perfect, and everyone should know this pleasure.

Thunderlane grits his teeth at the amount of pleasure in his throbbing stallionhood as its veins become more apparent. In an effort to slow her down to savor the motion, the stallion grabs at her flanks with his hooves and forcefully rubs her bottom up and down on his member to elicit the most possible pleasure out of him. Derpy doesn’t notice this, instead opting to bounce on top of him even harder than before, ruining his slow motion with one of quick vertical thrusts right into the soft cheeks hugging his member gently.

“Wee! This is fun!”

Derpy seems to have forgotten all about her service as well, now “riding” Thunderlane without a care in the world. She’s having plenty of fun, even as the undeniably lewd nature of the situation is completely lost on her. Right now, she’s fucking Thunderlane’s stallionhood with her flanks, and the smile on his face is just as wide as the one on hers.

Unable to hold back any longer, Thunderlane groans out in warning even as more thoughts of the grey mare’s flanks consume him.

(“The bubble butt... gotta cum all over it... bubbles...”)

Without so much as a single word escaping his lips, Thunderlane rocks his hips upward as spurt after spurt of thick stallion semen shoots up and begins to coat Derpy’s back and rump. All over her grey fur is now an off-white sheen, soaking into her and causing her to slow to a stop as she feels the liquid leave quite a mess on her.

"Aww, is the ride over?"

Even as her tail swishes lightly behind her and Thunderlane continues to pump into her flanks absentmindedly, Derpy doesn't seem to know what’s going on, now looking back at Thunderlane’s incredibly pleased face. With no idea of what to do next, Derpy questions aloud and holds a hoof to her mouth as she thinks deep, pondering thoughts.

“What’s all that sticky stuff, Thunderlane?... Thunderlane?”

With his member still twitching and throbbing slightly, Thunderlane is seen with his head tilted back and an impossibly wide grin on his face, as if he has died and gone to heaven. With his eyes closed, he can no longer see her flanks, and, as such, his blank mind seems to return to coherent thought... if only for a few brief seconds.

“D- Derpy... flanks... goooooood...”

Speaking single words during pauses and heavy panting, Thunderlane seems to pass out where he is, right outside his home with some evidence of what has transpired now pooling at his groin. Derpy then stands up and turns around to look at Thunderlane, watching him for any signs of movement and prodding him with her hoof delicately.

“Thunderlane? Huh, I guess he must really like rides!”

With that said, Derpy picks up her mailbag and slings it over her back, accidentally grazing the bottom of the bag in seed, all while blissfully ignorant of what had truly happened. Looking off to the rest of Cloudsdale, she remembers that she still has more deliveries to make and gasps aloud in surprise.

“Oh gosh, I almost forgot I still have to deliver a package to Lucky, too! I hope this one’s in here, next time. I can’t let a little fun distract me at work!”

Derpy merely smiles and flaps her wings to ascend into the bright blue sky once more, the fresh droplets of cum quickly leaving stains on an otherwise flawless behind.

Author's Note

Quite possibly one of the silliest ideas I've ever had, which is exactly WHY I wanted to write it. Combining my love for both the incorruptible innocent with unrelenting perversion is something I always wanted to try, and Derpy has a bubble butt. All arguments are invalid.

Got more chapters to go. Hope you like!

Chapter 2: A Heart-Shaped Meal

The door to Sugarcube Corner swings open roughly; the chime of the bakery’s bell signaling that somepony has arrived. Today, the new arrival is the gray-coated pegasus known as Derpy Hooves. Without missing a beat, Pinkie Pie pops up from behind the counter and gleefully greets her new customer.

“Hello and welcome to Sugarcube- Derpy!”

Upon recognizing her feathered friend, Pinkie cartwheels up and over the counter in a rather exaggerated manner before quickly dashing toward Derpy. Wrapping her forelegs over the stationary mare’s neck, she pulls her in close enough to rub their cheeks together in a playful embrace. Pinkie just seems very happy to see her good friend visit the bakery. Derpy seems to quickly match her excitement with a particularly jubilant smile of her own, her wings fluttering behind her as she greets her peppy earth pony friend.

“Hi Pinkie!”

Releasing her friend and returning to her stance on all fours, Pinkie playfully prods Derpy’s chest with her hoof and questions through an unbreakable smile.

“What are you doing here? Don't you have a job to be doing, miss mailmare?”

Alluding to her friend’s new employment, Pinkie giggles as Derpy’s face shines with pride and joy, even through her cross-eyed expression.

“Yup! I’m on the job right now, actually, but I just wanted to stop by for... umm...”

Derpy’s mouth scrunches cutely as she tries to remember just why it is exactly she came here for. She knows it’s related to seeing her friend Pinkie Pie at Sugarcube Corner, but other than that, her mind seems to go blank as another bout of forgetfulness overtakes her. Suddenly, however, a devastating grumble from below sounds all throughout the bakery, silencing both Pinkie’s giggles as well as Derpy’s mumbles as she stands there, bereft of thought.
With another joyful giggle, Pinkie immediately recognizes the sound and offers a suggestion.

“Sounds like somepony’s hungry! Would you by any chance be here for a.... muffin break?”

Derpy nods very enthusiastically, shaking her head up and down and creating a cartoonish rattling noise as she does so before she happily replies.

“Yeah!”

“Well...”

Pinkie Pie remarks, leading to her response as she quickly dashes back behind the counter and reveals a small basket filled to the brim with banana nut muffins, a treat she knows her friend adores.

“It just so happens that I just made a fresh batch of muffins before you got here!”

Derpy’s eyes widen in both surprise and immense joy at the sight of her favorite treat. Her wings flapping behind her gently before retracting to hug her sides, Derpy reaches forward as a dollop of drool falls from her tongue before speaking.

“Wow, Pinkie! You’re the best!”

Before Derpy can dive face-first into the basket, the muffins before her are whisked away and behind Pinkie’s back as she rolls her eyes and looks away with a knowing smirk.

“Ah ah ah... Not yet~”

Derpy’s eyes well up into tears as the smile on her face reverses into a terrible frown, deeply saddened by this turn of events as she stutters out.

“B- B- But muffins...”

“You can have the muffins on one teensy little condition.”

Pinkie leads the downtrodden mailmare back to the counter as she explains, trying to console her even though she had refused Derpy’s excitement only a few moments prior.

“Well, I was supposed to go on a picnic with my friend Twilight today. You know, that super smart unicorn who lives in the Ponyville library? But she canceled on me earlier and now I have no one to go with.”

Pinkie’s own pout rears its adorable head before she reaches behind her once more and pulls out an entirely different basket. This one, however, is adorned with pastries of all varieties, as well as a red and white checkered blanket draped over the right side.

“And I already made all this stuff! I can’t let it all go to waste!”

Derpy looks down at the assortment of treats inside, spotting fresh cookies, frosted cakes, pies topped with whipped cream, and many other desserts that couldn’t possibly fit in the basket. Looking up at her sugary sweet friend who tried to withhold muffins from her, Derpy cracks a smile of her own at the promise of a fun picnic.

“You drive a hard bargain, Pinkie Pie, but I’ll do it! Besides, picnics with Pinkie are perfect!”

Giggling at her alliteration, Derpy flares her wings out once more as Pinkie joyfully jumps into the air, her excitement too uncontrollable for her to simply stand there. Hopping over the counter with a leap, she wraps her foreleg around Derpy’s neck once more and replies with great enthusiasm evident in her voice.

“Now you’re speaking my language, pony pal! Let’s go!”

“Ooh, here's a good spot!”

Pinkie Pie announces, as they both arrive in the beautiful and scenic Ponyville Park. Derpy flies overhead, carrying the basket full of treats in her mouth before landing carefully on the ground right next to a tall tree, almost spilling the entire assortment before steadying herself. It wouldn’t be the first time Derpy’s clumsiness had played a part in accidentally ruining Pinkie’s well-done confectionaries, but thankfully she proudly rests the basket on the soft grass below, completely unharmed.

“Thanks Derpy! Could you lay out the blanket?”

Pinkie asks kindly, gesturing to the picnic blanket in front of her friend as Pinkie looks around for any other ponies. Apparently, not many ponies are out enjoying the beautiful day today. For some reason, as only a trotter and a stallion lying on a bench all the way across the park can be seen from where they are. Derpy hastily grips the end of the folded blanket and drops it on the ground, not exactly “laying out” the blanket as Pinkie had requested.

“Done!”

Just like that, Derpy wears a casual smile and looks to Pinkie Pie for praise upon completion of the task. Needless to say, Pinkie Pie isn’t exactly happy with her friend’s misinterpretation, but nonetheless trots over and smiles gently as she unfolds and lays out the blanket herself.

“Hehe, here, Derpy, I’ll get it.”

As Derpy watches Pinkie spread the sheet to cover the soft grass, it occurs to her that she has had a brief lapse in sense as she had not paid close attention to what her friend wanted. Complementing the thought with an appropriate facehoof, Derpy groans out.

“Oh, darn it! I forgot the unfolding part!”

Letting loose a few chuckles at her friend, Pinkie dismisses the misstep and brings her hooves forward to dig through the basket lying on the ground between them.

“It’s okay. Soooooo, what would you like first? A piece of double-layered caramel-covered cheesecake? Ooh, or maybe you'd like a slice of super delicious lemon meringue pie?”

Pinkie raises the options before setting them down on small paper plates across the blanket. After reaching in for a sealed container of fresh cookies, which she happily opens and digs into, Derpy helps herself to a few of the wonderful snacks loaded with chocolate chips.

“Wow, Pinkie! You made all this stuff at your job? Maybe I should have gotten into baking instead of being a mailmare.”

Trailing off with a giggle as crumbs fly out from her open mouth, Derpy wholeheartedly compliments Pinkie’s baking abilities. It makes sense, considering how often she is impressed by how talented Pinkie Pie is when in a kitchen. Of course, Pinkie Pie remembers the last time Derpy tried to assist her with baking something.

The kitchen was completely fine before Pinkie Pie left for a brief moment to fetch an apron. When she came back, however, not only were the ingredients all over the place and the kitchen in complete disarray, but as she walked in on the sight, Derpy’s mane spontaneously burst into flames. Needless to say, there was much clean-up involved and Pinkie never really wanted to remind herself of that day again.

Quickly clearing her throat in an attempt to be nonchalant, she remarks back to Derpy with a nervous smile.

“Oh no no, that's okay! I bet your mailmare job suits you really well!”

“You bet!”

Derpy answers through a joyful expression as cookie crumbs continue to spew from her mouth. She’s enjoying her food, to be sure, but like Pinkie Pie, she can be quite the messy eater.

“I delivered a letter to Fluttershy earlier, and she said she was happy for me!”

Derpy positively beams with pride as she swallows the chunks of chocolate chip cookies before licking her lips and giggling merrily. Pinkie can’t help but wear a kind smile of her own as she watches, picking up a piece of her aforementioned cheesecake as she replies.

“See, I told you it’d be fun! You look super hungry though, it’s like you haven’t eaten in days!”

“I do?”

Derpy’s wings flare out as she cranes her neck to look at her body rather self-consciously at Pinkie’s remark. Only a second’s pause is enough for Pinkie to add on as she prods her friend with a hoof.

“I mean you should eat more! Take your time, pegasistah!”

The gray pegasus mare breaks down into a laughing fit at Pinkie’s word usage, rolling on the blanket as Pinkie Pie merely watched in amusement.

(“How is she not big by now? All those muffins have to be going somewhere...”)

As the bright pink pony thinks to herself, she manages to remind herself of her promise to Derpy earlier today concerning the muffins that she loves so much. Without even a hint of hesitation, Pinkie reaches into the picnic basket and pulls out the smaller basket from within before holding out for the mare currently beside herself with laughter.

“In fact, here are those muffins I promised you!”

All at once, Derpy freezes in place as she eyes the basket of quick bread less than a foot away from her face. Her snout leans in closer as she inhales the sweet aroma, her eyes widening in anticipation of finally digging into the fresh batch.

“Mmm, muffins... Thanks, Pinkie!”

Just like that, Derpy closes her eyes and dives forward, her face completely disappearing into the basket as she literally gorges herself on her beloved muffins. Pinkie giggles, even as her hooves are forced to lower under the weight of holding up the basket with her friend’s face stuffed inside, even though she finds it quite endearing and even cute. Derpy didn’t seem to notice her friend, anymore, since the taste sensation of muffin bite after muffin bite keeps her quite preoccupied.

“Whoa, Derpy! Take it easy! I have to put down the basket first, silly.”

Derpy hesitates to free herself from her world of pure muffin delight, but still does as she’s told and watches Pinkie place the basket of muffins at her other side, leaving it there for Derpy to indulge as she pleases. Of course, the cross-eyed mare takes this opportunity as soon as it is presented to her, diving for the basket once more and forcing Pinkie to dodge to the left to narrowly avoid being tackled in Derpy’s mad dash. Derpy happily compliments the baking of her friend once more, even with a muffin top protruding from her mouth as she speaks.

“These are so good, Pinkie Pie!”

“I’m glad you like ‘em, Derpy!”

With another giggle, Pinkie watches as her pegasus friend goes to town on the muffins, eagerly devouring one after another with little care for how she looked. Pinkie doesn’t mind Derpy’s enthusiasm one bit. After all, muffins are her absolute favorite food in the whole wide world of Equestria. Pinkie Pie figures her hard-working friend is allowed to have as much as she wants.

Eyeing the picnic full of desserts to her left, however, Pinkie Pie licks her lips as she admits her own hunger before reaching towards it with a hoof. Suddenly, a quick thud sound spreads all throughout the park, accompanied by crushing and squishing sounds before Pinkie is found screaming in terror.

Before her eyes, Derpy has landed and crushed the entire basket full of treats with her thick rear end. Not only that, but she seems completely oblivious to it as well, focused on her muffin heaven as she bites into another one. Pinkie calls out in a firm, disappointed voice.

“Derpy! Look what you did!”

Derpy snaps out of her reverie to look back at Pinkie Pie, only to find the sight of mushed desserts everywhere behind her. Immediately feeling guilt wash over her, she tries to apologize to Pinkie as she drops the muffin basket carelessly.

“Oh no! Pinkie I’m so sorry! I just wanted to sit down but I didn’t remember the basket was there and then... whoopsie...”

Eyeing the ground behind her, Derpy looks down to see the damages for herself. Scattered pieces of what once were delicious confections are now spread out in a clearly squashed manner from the spot on the blanket. Pinkie herself almost seems on the verge of crying as she looks at the disaster site before her.

However, as her eyes travel upward, they fall upon the sight of Derpy’s luscious rump, now seeing just where all those sweet treats have gone. Both her cheeks appear to be covered in sticky strawberry syrup, chunks of caramel-coated cheesecake, portions of a pineapple pie, and even a surprising amount of whipped cream over her marehood. Pinkie Pie immediately finds herself drooling, despite the apparent blush on her face from knowing she’s openly staring at her friend’s ample posterior.

The worry and discontent previously shown on Pinkie’s face dissipates in an instant as her face now takes on a look of dazed curiosity. Her thoughts come much slower than her normal hyperactive state let on as she sits there in silence.

(“Wh- What?... Derpy’s... butt...”)

"Is it really messy?"

Derpy interrupts Pinkie with a question of her own, not able to see just how completely drenched she is in sugary sweets from this angle. Unable to tear her eyes away from the scrumptious sight, Pinkie Pie seems to mindlessly agree with Derpy, repeating her in an unnaturally dull tone of voice.

"Really... messy..."

Inside, Pinkie can't help but think how unacceptable that fact is. Derpy's bottom can't be messy; that will make her look unappealing and impossible to show off her most glorious asset. Holding firm belief in this way of thinking, Pinkie continues as she takes a brief step forward, inhaling the sweet scent of the crushed confections before her all the while.

“We should... clean you up...”

Derpy merely nods before looking around for something, unsure of herself even as Pinkie draws closer to her raised behind. Lifting her hoof to her mouth, she tries to think of how to clean the mess up, settling on a not-so-convenient option in her mind before speaking it out loud.

“I don’t see any showers around here, though.”

Before she can think of anything else, Derpy feels her flanks grasped at their sides by Pinkie Pie’s delicate hooves. Gently, they caress her smooth fur, spreading pieces of the desserts around as the pleasant aroma seeps into Pinkie’s nostrils. The sight of Derpy’s voluptuous behind associated with the savory smell of treats is too much for Pinkie. She mumbles out her own solution as droplets of saliva fall from her tongue onto the mess below.

“Don’t worry, Derpy... I’ll... clean it for you...”

“Really, Pinkie?”

Derpy seems ecstatic at the offer, completely ignorant of Pinkie’s true intentions. Her wings flare out behind her before she showers her friend with praise.

“Pinkie, you’re the best friend a pony could ever ask for!”

The pink earth pony didn’t bother with a response, instead allowing her long tongue to slip out of her mouth and lick her lips in hunger. Bringing her face as close as possible to the pegasus mare’s right flank, she slowly drags her tongue along it in an almost seductive manner.

Pinkie’s eyes roll back as she enjoys the sweet flavor on her tongue, quickly going back for another lick. Then another, and then another! Her cheeks flush red as a level of unexpected heat and desire fills her with a strong need she doesn’t quite understand.

The taste of delicious caramel cheesecake isn’t the only thing apparent to the hungry mare, however, as somewhere deep down inside her stirs a rewarding sensation. Each time she licks a section of Derpy’s behind, she feels a wave of pleasure wash over her, making her want more and more of this strange feeling.

(“Gotta make it clean... I have to clean it up for her... Make it look so nice...”)

Pinkie’s thoughts show no clear resistance, still dazed aside from the joy and jolts of excitement coursing through her. After just a few more licks along one side of the gray-coated rump, Derpy’s bubbly cutie mark is revealed and practically calls out to Pinkie for attention. Not wanting to disappoint, Pinkie Pie puckers her lips and kisses her flank attentively, knowing she is doing a good job before her mumbling words become breathy pants.

“That’s... one side... nhaa...”

Derpy giggles at the loving attention Pinkie pays to her bottom, trying to stand still even though Pinkie’s tongue on her fur tickles her with each movement. When Pinkie moves to her other side, however, she finds just as much, if not more sweets for her to devour in an effort to clean her friend. The lemon meringue pie she introduced earlier is now eagerly lapped up by the hungry mare, her hooves squeezing her flanks together all the while.

In order to savor the flavor and sensation of doing as she thinks best for Derpy, Pinkie approaches her flank from different angles. Her long tongue is quite skilled at drawing in every bit of food from her plump posterior, still drooling even as she moans throughout her task.

Finally, upon clearing off the other side of Derpy’s luscious rear, Pinkie finds the only thing left is the main event, so to speak. Nestled between the pegasus mare’s cheeks is her own set of netherlips, coated in what appears to be a healthy layer of whipped cream. Her bright pink clit can be seen under her, appearing as if it’s a cherry standing out nicely from the creamy texture surrounding it. The pink earth pony stares in silence as, inside, a mental war is waged over what little self-control the mare has left in her.

(“Wh- What’s happening? Why am I looking at Derpy’s naughty parts?”)

Taking a moment to think it over and straighten her thoughts out, Pinkie Pie pulls back from her up-close view only to have her entire vision encompassed by Derpy’s plush rear end. The daze returns to her face within seconds, her thoughts back to revolving around her task and what she needed to do.

(“Derpy’s butt is still messy... I’m her friend and I need to clean it up for her... all of it...”)

“Umm, Pinkie? Did you get it all?”

Derpy’s adorable voice sounds out once more as her tail swishes off to one side. Unable to resist what her thoughts are telling her to do, Pinkie grasps the pegasus’ flanks once more and leans in until her muzzle rests just above the delicious mess covering her marehood.

“Not yet...”

With those final two words, Pinkie completely surrenders to her desire to lap at Derpy’s irresistible ass, her tongue immediately heading straight for the hidden prize. Gripping the flanks as hard as she can, Pinkie’s face is completely buried between those soft mounds of fur in an almost heavenly embrace. Not foregoing her tongue work, Pinkie licks and sucks the mare’s labia with such fervor. More waves of pleasure seem to reward her for this act, encouraging her to lick as much as possible; to devote her time to pleasing the body of her marefriend.

A short distance away, another pegasus pony passes a few trees to get to the center of Ponyville Park. Upon landing near the fountain and folding her wings, the multi-colored mare lightly brushes her chest with a hoof. Looking to the park bench to see nopony on it, the look on her face becomes one of mild confusion as she remarks to herself.

“This is where Twilight said she’d meet Pinkie, right?”

The flyer known as Rainbow Dash covers her eyes from the sun to look all around the park to find her party-loving friend. She has come to fill in for her friend’s absence, knowing how important spending time with Pinkie is, especially when she feels ditched. Knowing not to make that mistake ever again, Rainbow Dash figures it is best to be there for her friend and just have a picnic together, even though she isn’t as big of a fan of sweets as Pinkie is.

Scanning the area with her eyes, however, she finally spots the pink pony seated on her haunches... nuzzling her face into the rear end of another mare. Covering her mouth to hold back from an immediate yelp of surprise, Rainbow Dash stands there in shock for a few brief moments. Her wings then spread out fully, uncomfortably stiff as her face flushes a deep red out of sheer embarrassment. Eyeing a nearby bush, she dives in it in hopes that the pair hasn’t seen her yet.

Unfortunately, her wings still protrude from the bush, making her quite easy to spot, even though she doesn’t realize it. Mumbling to herself in near stutters by this point, Rainbow Dash tries to comprehend just what she’s seeing over there.

(“What the hay is going on over there? Pinkie? Eating out... Derpy!? This is all kinds of wrong.”)

As she thinks that to herself, she doesn’t seem to notice Carrot Top and a young filly passing by. Both notice her incredibly stiff wings peeking out from the bush. Wearing a look of revulsion, Carrot Top gallops away, carrying the filly close behind as if to keep out of range of such perverse behavior. Rainbow’s eyes are too trained on Pinkie to look at anything else, the blush still present on her face as she watches.

Just as Rainbow Dash seems unable to fathom the act, she continues to watch as Pinkie slowly draws back, a trail of saliva connecting her to Derpy’s noticeably wet, but sparkling clean marehood. Moaning out in sharp breaths, Pinkie rubs Derpy’s amazing flank gently as she utters a few more words.

“There you go, Derpy... your rump looks clean as a whistle, now.”

Hearing this, Derpy flaps her wings in enthusiastic glee and flips around to hug Pinkie, practically lifting her into the air as her forelegs wrap around her kind friend.

“D’aww, thanks, Pinkie! You’re such a good friend!”

Without Derpy’s behind obscuring her vision and focusing her thoughts, Pinkie’s face seems to regain its energy, albeit somewhat confused as to the current goings-on. Why is Derpy thanking her again? And why is she suddenly not hungry anymore? Preferring to go with the flow, Pinkie pats her cheerful friend Derpy on the back and replies while wearing an obviously unsure smile.

“Umm, you’re welcome! I’m... glad I could help?”

Like always, Derpy is suddenly shocked as a thought occurs to her out of nowhere. Releasing her friend Pinkie and leaping up to hover above-ground, she groans aloud as she recalls a certain fact that has long since been forgotten.

“Oh no! I forgot I have to go back to work!”

Pinkie chuckles loudly, giggling briefly at her friend’s rather common forgetfulness. The irony of the situation is naturally lost on her.

“Go on, you don’t want to be any later than you already are. I’ll see you soon, okay?”

“Okay! Bye, Pinkie Pie!”

Derpy merrily responds to Pinkie’s gleeful dismissal, now needing to get back to work in a rush. She does want to keep her first job, after all. The earth pony smiles at her gray-coated friend as she flies away before turning to look down at the crushed basket in front of her. A gasp in shock is all she can eke out, hundreds of thoughts swarming her head about this absolutely devastating sight before her.

“What happened!? Why would anypony ruin all those desserts I made!?”

In an instant, Pinkie Pie’s poofy mane deflates as she sobs over the loss of her delicious treats. Rainbow Dash notices her odd behavior and exits the bush, her wings finally freed from the stiffening blood flow to gently make her way over to her suddenly depressed friend.

“Uhh, Pinkie?”

Whipping around to find her friend Rainbow Dash staring at her, Pinkie’s mane quickly re-inflates with the sound of a party favor bursting free. As excitedly as she can manage, the pink-maned mare offers her cheerful greeting.

“Oh, hi, Rainbow Dash! What’s up?”

Rainbow Dash looks at Pinkie as if she has finally gone crazy. Still flustered by what she has just seen, she tries to explain her reason for being there as she lands on all fours.

“Twilight wanted me to catch up with you since she couldn’t make it, and I didn’t see you at Sugarcube Corner, so I figured you’d already be here, but...”

Rainbow Dash halts in mid-sentence as she recalls her friend diving face-first in between the hind legs of a mare, her wings threatening to burst free from her body with arousal. Thankfully, Pinkie interrupts her silence with an explanation of her own.

“Oh yeah! Derpy stopped by and I had the picnic with her instead!”

“Y- yeah, but... you and Derpy? Doing... that?”

The rainbow-maned pegasus can’t seem to remember a time where she stuttered so much. Maybe when she came face-to-face with the Wonderbolts that one time, but even then she certainly wasn’t as flustered as she is at the moment. Of course, Pinkie doesn’t catch the hint at all, tilting her head to the side in confusion as she questions her friend’s remarks.

“Doing what? Enjoying some muffins and pastries? I don’t see what’s so strange about that! Especially not when they were delicious!”

At that, Pinkie Pie thirstily licks her lips once more, catching drops of an unfamiliar liquid still present on her messy lips. This naturally reminds Rainbow Dash of what she saw, once again causing her face to heat up in embarrassment. Unintentionally tripping over her words once more, Rainbow Dash leaps into the sky and shouts back at her friend who remains on the ground.

“Nevermind! I’ll see you later, Pinkie Pie!”

“Okie dokie lokie! Bye, Rainbow Dash!

Having said goodbye to her dearest friend, Pinkie’s curiosity causes her to lick her lips another time, this time carefully evaluating the taste still on her tongue.

“Huh, I don’t remember having anything so juicy earlier.”

Chapter 3: Cause and Effect

As Derpy Hooves casually trots over to her final destination for the day, she whistles a merry tune to herself. All the while, she wears a rather tired expression. Her day has been rather exhausting, but she knows her hard work will be worth it when she earns her first week's pay. Just imagining finally being able to make a living on her own is enough for the young and freshly independent mare. She makes her way along the path to Sweet Apple Acres, blissfully unaware of the cloud hovering high above behind her.

The cloud is being used as makeshift cover by none other than Rainbow Dash. It seems the fastest flyer in all of Equestria has resorted to sneaking around and watching the ditzy mare from her aerial vantage point. Since the sky blue pegasus had seen her good friend Pinkie Pie act so strangely, she has decided to follow the blonde-maned mare on her mail route to see if any other strange events occur.

Alas, letter after letter, package after package, and yet nothing out of the ordinary has happened. Not a single pony Derpy has delivered to acted any different than usual. To be fair, Rainbow Dash did find herself in need of a quick mid-afternoon nap, but she merely shrugged it off afterward, convincing herself that nothing too exciting must have happened in the meantime.

Derpy Hooves eventually arrives on the path to Sweet Apple Acres’ own Apple family. Taking a moment to glance off towards the sunset, she remarks aloud to herself just how late it's gotten.

"Oh wow! It's really been a long day, hasn't it? It'll be dinner time soon!"

Her weary legs bring her right to the doorstep of the apple family's humble abode. Just as she is about to knock on the door, however, Derpy hears a familiar Southern accent call to her from afar.

"Well, hey there, Derpy! Ah'm over here!"

Upon hearing the voice, Derpy's first instinct is to look directly above her. She isn't so good at directions, after all, having once delivered a package to the wrong side of Ponyville all because she mixed up "east" with "weast." The Pegasus soon locates the source of the voice with a quick look behind her, spotting the orange mare trotting toward her with a friendly smile on her tired face.

Applejack approaches slowly, almost dragging her hooves along the freshly plowed field as the farming pony draws nearer to her visitor. She notices the golden eyed Pegasus isn't her usual mailmare, and gives an odd head tilt in a show of her curiosity before speaking.

"Can't say ah was expecting you here."

Derpy is, of course, more than happy to educate Applejack on her reasoning for being here. The earth pony walks right up to her, smiling to show her joy at seeing another one of her good friends.

"Oh, Raindrops is out today, she pulled a muscle in her wing and had to stay home."

Applejack's expression shifted to one of brief concern for her injured fellow pony.

"Now that there's a darn shame. Well, thanks for stopping by and deliverin' in her place! I much appreciate it."

Derpy nods in the same giddy, exaggerated fashion as always. She’s happy to assist her mailmare friend by taking on her route as well. Unfortunately, all the additional work is beginning to take its toll, and Derpy ekes out a tired sigh of exhaustion to demonstrate. The gray-coated mare has been flying all day, and she barely has enough strength to get back to her home in Cloudsdale.

("Oh, home sweet home. I can take a nice shower and just relaaax...")

The thought of soothing warm water washing her of all the dirt and sweat she has accumulated all day briefly distracts the aching pegasus. Applejack can tell by the mare's dreamy expression that her wandering mind has drifted off once more. Clearing her throat brings Derpy's focus back to the present and remind her that she has an actual task to take care of at the moment.

"Oh yeah! I brought you a letter!"

AJ offers a weak smile at the mare's merry disposition, finding it rather peculiar that a girl as old as her still "acts like a young'n," in her own words.

"Well, I'll be! Who's it from?"

"The mayor! I think it's a thank you note for helping rebuild Town Hall after the, umm... incident."

Derpy seems to have some difficulty remembering the right word for the little accident she had caused a few weeks prior. Sure, it was the third time she had been tasked with moving storm clouds in that direction, but it was still tricky for an easily distracted mare such as her. A few stray thunderbolts and Town Hall was left a pile of smoking rubble, and Derpy was out of her old job as a weathermare.

To be honest, Derpy doesn’t like remembering that time, considering the fact that the so-called “incident” is what had gotten her kicked out of her parents’ home after being deemed “too much of a hassle” by her own father. The golden-eyed mare didn’t let it get her down, though, because that was just the push she needed to become the independent mare she is today.

After staring off into space for a few seconds, Derpy notices an orange hoof enter her field of vision and shakes her head free of the memory distracting her.

“Uhh, y’alright there, girl? Having a flashback or somethin’?”

Applejack questions Derpy kindly, even as her mild annoyance at the mare on her porch blocking her way to rest and relaxation quite clearly shows. Derpy merely offers an apologetic smile for daydreaming

“Hehe, sorry.”

The pegasus reaches back toward her bag hanging over her side and manages to get the top flap open with her hoof before having some difficulty finding the right letter. Pouting slightly, she turns back and dives face-first into the bag, throwing off her balance and causing her to yelp as she tumbles forward onto the hard wood porch below.
Applejack, being the caring pony that she is, chuckles slightly at the mailmare's clumsiness. Trotting after her, AJ questions the gray pegasus who finds herself face down for what feels like the millionth time on today.

"Whoa, Derpy, that was a mighty nasty fall. Are you... uhh..."

Applejack finds herself stammering slightly when her eyes focus on the sight before her. Not only has the dangerously clumsy mare accidentally buried her face between the floorboards, she's positioned in such a way that her plush rump is on full display. AJ is taken aback for a moment while those bubbles adorning Derpy's flank catch her eyes with relative ease.

The world around her disappears; the bright, colorful farm she has known all her life fades away momentarily into darkness. This leaves the usually dull-colored pony to appear as if she’s a golden god of salvation to the hard working mare. Something for her to enjoy... to please... to worship.

“Umm, Applejack? Are you still there?”

Derpy’s words are faint, even distant to the orange pony while she draws closer. Briefly mumbling, Applejack leaves her mouth agape as she seats herself directly in front of the captivating sight before her. Slowly, she brings a hoof up to gently prod the beautiful behind, her mind struggling to keep up with her actions.

(“Wh- What in the hay? Why am ah touchin Derpy’s... bubble butt?”)

The questions fail to form on her lips. A mere gasp is all that escapes the honest mare before she catches herself lewdly licking her lips. Derpy, feeling rather left out of whatever is going on behind her, mutters aloud in another attempt to get through to her preoccupied friend.*

“I’m kinda stuck, I think.”

As if to demonstrate her claim, the gray-coated mare tries to tug herself free from the broken floorboards. Her wings flutter to no avail, and AJ chuckles at the sight. She has always thought of Derpy’s behavior as cute, but after seeing her this close, she can’t help but feel something else for the trapped mare.

Soon after, the orange pony does something rather unlike her. Applejack brings her face close enough to nuzzle her cheek rather affectionately on the soft fur adorning Derpy’s flank. Almost instantly, a wave of pleasure courses through her, causing her to swoon happily as a result. She feels encouraged to continue, and doesn’t see anything wrong with her actions.

Her hooves wrap around Derpy’s hind legs and pull them against her face in what appears to be a surprisingly gentle hug. This unexplained need to be so close to Derpy’s behind is strange to the suddenly affectionate mare. However, she can’t seem to find a single resistant bone in her body to want to pull away.

(“So soft... Sweet Celestia, she’s like a pillow...”)

AJ squishes her face against Derpy’s posterior once more, reveling in the smooth, flawless texture of the pegasus.

“Don’t you worry none, Derpy... Ah’ll help ya and this sweet, sweet ass ah yours~”

“Huh? Okay, I guess...”

Derpy can’t help feeling awkward upon hearing Applejack refer to her rear end, but decides to ignore the remark in favor of getting free from her wooden prison. Unfortunately, the gray-coated mare receives a different kind of help as she feels something warm and wet teasing her marehood. She lets out a small gasp of surprise before the eager earth pony behind her practically dives between those furry globes she’ so invested in.

AJ’s muzzle is so deeply latched onto Derpy’s own marehood as her tongue works the bright pink inner folds hidden from view. Her tongue darting in and out of the mare’s sex causes her to make noises she had never heard herself make before.

“Uhh, so what are you gonna do to help me get out, AJ?"

Derpy questions nervously, seemingly ignoring the pleasure coursing through her body as just another funny feeling. Her friend's mouth is currently occupied, however, as Applejack refuses to spare another moment away from Derpy's all-encompassing rump.

("This perfect behind... This perfect lil’ pussy... I could taste this sweet honey pot all night long!")

The musky scent of Derpy’s luscious behind clouds AJ’s mind as she darts her tongue in and out without mercy. Unwilling to miss even a drop, she laps at her sensitive muff like a dog thirsting for water. As strange as the feeling of somepony's tongue on her may be, Derpy's one-track mind is so focused on the problem at hand that she can't feel a thing!

("Oh, am I dirty down there again? Darn it, I hope Applejack hasn't noticed how sweaty I've gotten.")

In truth, the gray mare's sweat-matted fur only arouses.the hard working farmer even further. The appreciation for the fruit of her efforts combined with the feminine scent filling her nostrils nearly drives her wild with desire.

The feel of her face being so fully eclipsed by those warm, pillowy cheeks makes her heart melt as she offers a deep moan of content. Unfortunately for the orange-coated mare, an intruder with a familiar deep voice interrupts her from behind.

"Applejack? What are you doing!?"

("Huh? Big Mac?")

AJ recognizes her older brother's voice as it calls to her, but her dutiful task keeps her busy for just a few more moments. This only raises the deep red stallion's suspicion as he bears witness to the lewd sight of his younger sister with her face entombed in another mare's behind.

His sibling is entirely absorbed in the task at hand, showing sudden passion and devotion to something he thought she would never do. The spellbound mare finally manages to pull away from the enchanting rump and turn to her brother, the dazed look on her face sobering up the longer she speaks.

"Oh, Big Mac! Ah was just... huh... what was ah doing?"

Applejack scratches her head, confused as to the gap in her memory. A golden blonde tail swishes next to her, drawing her brother's attention to the full rear end of a familiar mare on display. He can't quite place it, but he knows he has seen that bottom before, and even now it holds his attention more so than any other mare's like it.

His body stiffens up immediately, his eyes focusing as they fall on the marvelous sight that is that flank where those irresistible bubbles rest. It looks to him like his little sister is doing a little exploring on the mailmare, which is strange in and of itself, but now he finds himself unable to care that Applejack was doing something so lewd. With a glorious behind like that, who wouldn’t wanna bury their snout between those cheeks?

Making his way closer to her, Macintosh presses his sturdy hoof into that plush flesh, immediately feeling it sink into the soft fur surrounding it.

“You... you weren't diving into this mare's behind, were ya?”

Derpy twitches slightly at the feeling of such a strong limb poking her bottom, but manages to come to her senses afterward to ask for a little assistance.

“Oh hi Big Mac! I’m a little stuck, could you maybe pull me out?”

Big Mac is cognizant enough of the situation to know he has to help the poor mare. So, with a slight lean forward, he grabs the pony’s mane with his teeth and yanks backwards, pulling her head free and leaving her resting on the ground as his weight shifted to lay atop her.

“Whew! Thanks, I really appreciate-... Big Mac?”

Derpy halts as she feels the stallion behind her lean over her entire body almost menacingly. AJ notices this, but her eyes find those bubbles once more, and her train of thought derails while a suggestive grin spreads out on her face.

“Ooh, looks like mah brother wants his turn with ya too, Derpy!”

Macintosh doesn't say a word as he locks himself in a mating position, pressing all four legs around Derpy’s sides to prevent her from fleeing. His throbbing stallionhood pokes her cheeks, ready and willing for any illicit behavior that his body so suddenly desires. Unsure of what’s going on, Derpy merely squirms when she feels the stallion’s body rubbing against her.

“Hey, stop that! Nheehee... that tickles!”

Derpy tries to hold back her giggles even as Big Mac aims his love muscle right for her forbidden zone. His flared tip prods her tailhole, and Derpy’s tail shifts aside on its own while her rump slowly nudges back towards him. Big Macintosh is more than happy to oblige. He gently pushes forward and her ass cheeks spread to accommodate such a massive member.

As much as one could assume that Derpy would be in an immense amount of pain from unlubricated anal sex with an abnormally large cock, Derpy doesn’t feel a thing besides ticklish. He can’t get much more than a few inches past the tip inside, but he still grunts out in pleasure when he feels her body work him deeper inside her of its own accord. He’s surprised as she breaks down in a fit of chuckles, but refuses to question the glorious ass he now has the pleasure of satisfying.

“C’mon, quit it! That feels funny!”

Derpy never understood these “funny feelings” when she has them, but her body is too busy getting reamed to care. AJ sneaks up next to the pair and squishes her face against Derpy’s plump flank, nuzzling into her once more as it takes a much harsher pounding from AJ’s sibling.

“Ain’t it just the best you’ve ever seen, Big Mac?”

Her dreamy voice barely registers in the stallion’s mind as he begins pumping forward, his body trying to fit as much as he possibly can inside the mailmare. A mere “eeyup” is all he manages in response through a groan of annoyance at being unable to fulfill the task of hilting himself inside Derpy’s rear end.

While Derpy certainly doesn’t mind the rough pounding her irresistible behind is taking, she doesn’t much care for the feeling of the rest of her body pushed down into the hardwood floor and her face squishing against the floorboards. Feeling uncomfortable, she ekes out a complaint in her still rather innocent tone.

“Uhh, it’s getting kinda late, I really have to- GO!”

Derpy’s words are punctuated with a loud slapping noise as AJ brings a hoof down over her gray-coated flank and leaves a large red mark in its wake. Trying to calm her after the sudden sting, AJ rubs her hoof over the smooth fur gently and coos in her sweetest voice.

“Not so fast, Sugarcube. Just let us enjoy your bottom just a lil’ while longer.”

A little while longer comes faster than either of them could have anticipated. Big Macintosh feels Derpy’s body clinging to him and begins to squeeze, drawing him closer to climax without giving him a chance to please her. The sudden tightness causes him to rear backwards, leaving Derpy free to move until he thrusts his hindquarters forward and dumps his entire sticky load inside her ass.

The gray pegasus pouts adorably and waits for Big Macintosh to finish whatever he’s doing. The mare fails to notice the growing heat inside her bottom even as the thick semen fills her to the absolute brim. Her bottom, however, seems to revel in the sensation, voraciously sucking in every last drop the stud can offer.

Unable to handle the force of his own orgasm, Big Mac falls backwards and lands with a loud thud onto the floorboards, the rest of his release spewing out over himself and leaving a nasty mess of a stallion. With his sharp pants ceasing, the dizziness overwhelms him and he lets out one last, quiet remark before falling unconscious.

“That... plot...”

Applejack chuckles at her brother’s weakness, but can’t fault him for enjoying Derpy’s amazing “plot,” as he called it. The orange farmer pony moves close to admire the sight of those mesmerizing bubbles once more, complimenting the impressive behind in her still dream-like tone.

“Not just any plot, Bg Mac. Derpy’s got the best plot in all of Equestria!”

Derpy struggles to stand up straight, feeling a weakness in her legs and something sticky dripping from her nethers all the while. She turns to look back at AJ, forgetting the comatose Big Mac, and questions her.

“Why do you say stuff like that?”

The poor pegasus pony seems positively perplexed by the events that have unfolded today, and rightfully so. Her friend Pinkie had cleaned her no-no zone, her friend Applejack was acting weirder than she was at Applebuck Season, and Big Mac had her pinned to the ground for the past 5 minutes for no reason! Times sure are tough for Derpy, but Applejack explains herself through a smug grin and closed eyes.

“Only on account of it being true. Ah don't really know why, Ah just know ah can't look away after laying eyes on such a mighty fine behind like yours. Speaking of which, Ah think ah could use a round of seconds of that perfect little pussy, Derp-”

Applejack stops when she opens her eyes and finds Derpy has flown away, leaving nothing but an empty space in front of her. Shaking off the strange fog covering her mind, she looks around to find a hole in her floorboards and questions herself.

“What the? What am I doing out here so late?”

Turning to her side, she sees Big Mac on his back, snoring with his chest covered in semen and his horsecock out in the open. Leaping backwards in surprise, Applejack exclaims with eyes full of fear of what could have happened.

“Oh no, not again!”

This strange scene leaves Rainbow Dash with her mouth agape, watching from her secret cloud and wondering what in the world she just witnessed. Thinking aloud, she ponders as she watches Derpy fly off to her own home in Cloudsdale.

“Something about Derpy’s... flanks? I have got to get to the bottom of this. Hopefully before the author can make another butt pun.”

With that cheap joke out of the way, Rainbow Dash abandons her cloud and flies after the gray pegasus, hoping to find out the truth.

The truth about Derpy’s plot.

Chapter 4: Acknowledgment

Night time in Cloudsdale is always such a peaceful time for the typically busy floating city. All the little fillies and colts are sound asleep while the hard-working pegasi try to rest after a long day. Most ponies prefer to get their shut-eye around this time, since there isn't much else to do in Cloudsdale. The nightlife is down in Ponyville, but right now, that's the farthest thing from our protagonist (or some such character archetype) Derpy Hooves' mind.

After that last little encounter with the Apple siblings, the ditzy mare decides that what she needs is a nice shower to wash away all those uneasy feelings she's had up to now. Her aching body makes its way to the bathroom step by agonizing step. She's just happy to be off her wings, so to speak, and even happier since mailmare work is far less demanding than her last job.

All those letters and packages are whisked from her memory as she takes her first step under the columns of running water. Immediately, the sensation of relaxing muscles and cleanliness rolls over her withers.

"Aaah, that's so nice~"

Careful not to slip, she grabs her trusty scrubbing brush from its home in the soap bin and gets to work rubbing in that wonderful pink soap, soothing her grimy coat and making it really shine. The bubbles gathering on her fur and washing off into the tub always made her giggle, but tonight she simply has too much on her mind as she recalls the events of the day with a weary expression.

"Gosh, I'm so sore. Especially my flanks."

Derpy thinks to herself aloud, seeing as no one is around to hear her. Normally, she would hum to herself under the relaxing hot water and perhaps break out in song if she had the energy (regardless of her terrible singing voice). Upon mentioning her flanks, however, she remembers the confusing behavior of the ponies surrounding her today and begins to speculate on just what could have caused those odd reactions.

"Applejack never acted like that before, and stallions kept giving me those weird looks all day. What could it be?"

The pegasus' tail swishes playfully behind her, as if her body seems to know something she doesn't. Grabbing the nearby bottle of shampoo, she notices her tail's little gesture and remarks with a slight gasp.

"Whoa! Maybe my tail is a pony charmer!"

The little fantasy only lasts for a moment before she breaks out into a giggling fit. She's no unicorn, and she certainly doesn't have a horn hidden under her tail. If any pony would know that, she would. Still, her brief outburst of silliness fails to mask her growing suspicion over the strange events that have occurred.

"If it isn't my tail," she muses, "then maybe it's my cutie marks?"

As if on cue, her rump gives a jiggle, the fat covering her behind seemingly taking pride at being noticed. Derpy is one oblivious pony, unfortunately, and her rear end's little wiggle goes completely unnoticed as she scrunches her face in confusion. Bewildered beyond belief, it seems she can't figure this one out on her own.

("Maybe someone smart like Twilight will know. Maybe there's a book on cutie mark magic or something like that.")

Derpy shakes off her endless speculation after a few minutes. Intense thought gives the poor mare a headache, and the loud sound of the shower certainly isn't helping matters. She turns off the water and reaches for her towel by the sink when she hears her doorbell ring downstairs.

"Huh? Somepony at the door this late?"

Not one to keep a guest waiting, Derpy merely grabs the towel between her teeth and flings it over her back for now, carefully making her way down to the door without the use of her wings. She can't very well fly with all the water weighing on her fatigued feathers, after all. Without a clue as to who is at the door, Derpy grabs at the handle with her teeth and yanks backward, flinging the door open and turning back to see her surprise visitor.

"Hey, Derpy. Can we talk?"

The same rainbow-maned pegasus that has secretly been following Derpy around finally makes herself known as she greets her cross-eyed friend with a curious grin. Golden eyes tinged with a bit of exhaustion shine back at Rainbow Dash, happy to see a friendly face even this late at night.

"Sure! C'mon in! What do you wanna talk about?"

Derpy watches as her friend makes her way into the house with clear trepidation showing in her movement. The gray-coated pegasus closes the door behind her, eager to hear what Rainbow has to say. It must be important if she had to fly all the way to Derpy's home to tell her.

"Well, I've been seeing you around lately and I... nnh, this is so embarrassing..."

Dash's wings flutter behind her as she tries to put together the words to explain herself. She kept telling herself all day that this isn't real; that her ditzy friend since kindergarten hasn't suddenly had all the mares and stallions after her ass like it was the best thing since sliced bread. Unfortunately, all the evidence thus far has led her to this point, and she knows she will freak out if she doesn't take her chance to ask Derpy what in the hay is going on with her.

Seeing Rainbow Dash with that embarrassed look on her face and those outstretched wings makes Derpy gasp in surprise, a deep rosy blush forming on her cheeks all the while. She stirs the cloud beneath her with a feather-light hoof like a common schoolfilly. She turns her cross-eyed gaze away to avoid eye contact as she misinterprets this surprise visit to be something else.

"Oh, Rainbow... I had no idea you felt that way about me..."

Rainbow merely folds her wings tight and looks at Derpy in that same dumbfounded expression she often wore around this confusing ditz of a mare. Shaking her head and leaping into the air for a moment, she swings her forelegs back and forth in a defiant "no way" motion as she retorts.

"What? No way! Not ever! That's not what I meant, Derpy!"

Derpy's blush disappears as quickly as it arrived before she cocks her head to the side in her confusion. The gray-coated pegasus normally had a hard time following other pony's trains of thought, even more so than she did following actual trains. Those things were fast.

"It's about you. Uhh... a certain part of you."

Rainbow Dash settles back onto the ground and tries to express herself as clearly as possible without completely broaching the subject. Of course, Derpy still doesn't notice the subject she's dancing around, instead growing more and more curious by the second as to what her friend Dashie is trying to imply.

"Huh? What part? Is it my mane? I've been using this new shampoo, and it's working great! You can try some if you wa-"

Derpy gets a hoof stuffed in her mouth to stop her from trailing off any further.

"Oh come on, Derpy! You can't be this dense!"

Derpy doesn't quite recognize the word. Is Rainbow Dash trying to say she's fat? That isn't very nice of her. Knowing her slow-witted friend hasn't quite caught on to her meaning, she explains as she paces around the room, leaving frustrated hoof prints in the cloud beneath her.

"Your picnic with Pinkie Pie, that incident with AJ and Big Mac, ring any bells?"

"Oh, I don't have any bells to ring. I had to get rid of my old wind chime a few days ago, the neighbors said something about it being a bad idea up here."

Rainbow Dash groans in utter frustration, wanting to tear her hair out at Derpy's continued misunderstandings. Grabbing her by the shoulders, the aggravated pony stares into those golden irises and, while unable to follow both of them, bluntly addresses her.

"It's your backside! Haven't you noticed that whenever ponies look at it they want to... you know?"

Derpy seems taken aback in utter bewilderment, craning her neck away from Rainbow Dash to look at her own behind. She ponders her friend's words in deep thought, wondering what Dashie means by that remark.

Her ample behind, while still wet from the shower, doesn't look any different from normal. Her plump spheres still have the same bounce as always, her tail seeming to agree as it playfully swishes back and forth at that thought. Unsure as to what other ponies see that she doesn't, Derpy turns around and lifts her rump up for Rainbow Dash's viewing pleasure, asking aloud in the most genuine voice she can muster.

"I don't get it. Why would anypony wanna look here?"

Rainbow is thrown completely off by the sudden full view of Derpy's rump, blushing wildly in surprise at her friend revealing herself like that. Trying to retain her decency, she backs a few inches away, and stammers as she fails to cover her sight from the marvelous sight.

"D- Derpy, no! Don't show me your..."

The gray pegasus turns her stare back to Rainbow Dash, who freezes in place at that moment. Her eyes firmly lock onto those bubbles adorning Derpy's flanks, and in mere seconds, she loses her frustrated tone as she mumbles out the next few words.

"... your ass..."

All of a sudden, realization flows over Rainbow Dash like a tidal wave of knowledge. Derpy Hooves simply has the best rear she's ever seen in her entire life. Better than any stallion's, better than any other mare's! If she had to choose between Celestia's and Derpy's cheek-to-cheek, the blonde-maned pegasus would win by sheer volume. The soaking wet fur only attracts her gaze as she sees how perfectly round and statuesque those orbs are for the first time.

Dash feels an inner desire she hasn't felt before: a need to close the gap between her face and that plot to praise it like she praises her poster of Spitfire each night. With Derpy standing there in confusion, her blonde tail flicks across Dash's snout, begging for attention that's too mature for the naive mare to understand. Rainbow complies, inching forward until she can fully embrace both glorious spheres of beauty and bring her mouth ever so close to her right cheek.

Naturally, this fills Derpy with another sense of concern for her close friend. First, Applejack, and now Rainbow, too!? She worries that whatever is going around might be contagious before carefully questioning Rainbow Dash with her charmingly sweet voice.

"Rainbow Dash? Are you okay? You went all quiet."

The rainbow-maned pegasus is too absorbed in the generous amount of butt flesh she's faced with to respond. Instead, she rubs Derpy's flanks with the soft undersides of her hooves, trying to cope with what she's doing even as a small smile graces her lips.

("What's happening!? I wasn't supposed to look at it, but... now I can't look away!")

A familiar dazed look becomes quite apparent on her face, but Rainbow merely closes her eyes and accepts her fate. Worshiping this plot must be as good as everypony makes it out to be if she already feels this euphoric. A sudden flat tongue grazes Derpy's fur, and she quickly jolts backward, laughing at the surprisingly delicate sensation.

"Hee hee! Rainbow, I'm ticklish back there!"

While her warning is heard, Rainbow Dash doesn't seem capable of heeding it as she continues lapping at the wondrous taste of Derpy's flank. Wet fur isn't exactly known for its taste, but it doesn't matter to her so long as it belongs to this bubbly mare's fine, thick behind.

The greedy teasing catches Derpy off-balance, however. As Rainbow pulls her in closer, she eventually pulls Derpy back so hard that the combined weight of the pegasi shift backward and onto the floor. This leaves our gray-coated innocent pony seated comfortably while our snooping sky blue mare is buried completely in ass. With her muzzle blocked off to the outside world, Rainbow Dash closes her eyes and elegantly contemplates her situation.

("This is it. This is how it ends. Suffocated after Derpy sat on my face... what a way to go.")

Muffled noises erupt from beneath Derpy, causing her to squeal at the vibrations below. It isn't until Rainbow Dash pushes on Derpy's flanks hard enough to bruise that she gets the idea that Rainbow might not be comfortable. After the few seconds of being unable to breathe felt like an eternal paradise for Rainbow, the blonde-maned pegasus lifts herself up off of her friend and turns to see if she's conscious.

"Oh gosh, Dashie, I'm sorry! I kinda... fell."

Precious air rushes back into Rainbow's lungs, allowing her to sputter for breath and shake herself free of the trance she was under. She looks around the room to find she's now on the floor, looking up at her friend Derpy's worried expression and baffled by the gap in her memory.

"Ugh... What happened?"

Rainbow's head feels like it's just been crushed between two soft, yet firm, pillows. The sky blue pony has trouble remembering the predicament she had gotten herself into only moments ago, and a fresh, pounding headache (perhaps from blood flooding it) isn't doing her any favors. Derpy reaches down and helps her friend to her hooves, wondering the same thing and trying to make sense of it herself.

"I don't know! You started talking about my backside and then you started licking it and acting all weird."

A look of shock and terror spreads over Rainbow Dash's face. She had fallen for it after all! The same weird spell Derpy's flanks had cast on all the other ponies had affected her, too. The knowledge that she actually licked her close friend's flank is enough for her to need a long shower of her own when she gets home.

"Oh no, it's worse than I thought! I- I have to go. Just... don't do it anymore, okay?"

Dash's words fail her through a now permanent blush and a befuddled stammer. She then takes to her wings and flies right through the top half of Derpy's door, haphazardly trying to get as far away from the considerably manipulative mare. She almost caused the door to fly off its hinges from the very force of her escape.

Once again, Derpy is left alone, positively perturbed and shaking her head at the events that have transpired.

"Do what anymore? I still don't get it."

The always adorable mare sinks to the floor, pouting as she worries she might have seriously upset her friend. Turning around to eye her plush rump, she still doesn't understand why all of this is happening to her and not some other pony. The only answer she gets is her own mischievous tail swishing from side to side on the floor. Whether it's from her own frustration or from her body's joy at being pleased, she'll never truly know.
