Plot Power

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.
