Derpy opened her wings and jumped off the cloud. The wind brushed against her face as her glide took her to the next cloud. She landed on it, unfazed by the unsatisfyingly soft collision with the material she was so used to. She took a moment to reorient herself to the cloud.
 
She re-adjusted her courier's cap, then quaintly trotted towards the postbox on the edge of the cloud. She swiftly plucked a couple of letters from one of her side bags, and slid them into the box's slit opening.
 
With no time to loose, she jumped off the edge to glide towards the next cloud, this time with much more speed. She bounced off a few clouds on the way, and perhaps accidentally disturbing a lazy pegasus's nap once or twice. (Perhaps accidentally kicking them off their cloud once or twice)
 
She finally reached the next post cloud, and quickly stuffed the next few letters into it. This was the last cloud on her rout, the rest of it would be on the ground.
 
Derpy rested for a few seconds, then ran at the edge of the cloud and jumped off much like she had the last time, but she tucked in her wings and swan dived towards the ground like a graceful...well, like an ugly duckling. But a cute ugly duckling.
 
The mailmare closed her eyes for a moment as she fell. She enjoyed the feeling of falling. She enjoyed the wind against her face and the constant tug against her hair and tail. She would enjoy it all day if the ground was so close by.
 
Just like that, her moment of bliss was over. Her wings flared open and her speed dropped slowly. She angled herself to reach town hall by the end of her glide. It'd be a short flight to-
 
Derpy's sense of direction (and sense of anything else) was completely destroyed when she was hit from behind. By what, she couldn't quite say. Her head ached and her hind legs felt cramped...wait, cramped?
 
Before she could react any further, a strange, tight wetness was tied around her body and around her forelegs. She looked down to inspect herself. She didn't like what she saw. (but you might!)
 
Around her midsection appeared to be the mouth, chin, and neck of a blue pony. Only when it slithered up her body did she realize what was happening and screamed.
 
She sank further down into the pony's throat. Her wings burned as they were bent the wrong way by the surrounding lips, escalating Derpy's cry for help to a cry of pain. The pony slurped her up to her neck before she thought of something sensible to say.
 
"What the F*Muffin*ck is going on?!"
 
She could feel the predator's lips wrapping around the back of her head as it was forced to crane upward.
 
"What did I do?!"
 
The predator's lips stretched across her face, leaving nothing but her muzzle to the visible world.
 
"Why are yo-"
 
With a final gulp, Derpy slid down the pony's throat and into it's hot stomach. It was tight and uncomfortable as she was contorted into a ball. The only words she could really hear were "Hah! Thought you could outrun me, did ya?"
 
Derpy wept before the long process of digestion began (unless your not into that, then she just sat in there for the rest of the and missed clocking out. Oh, the lecture her boss will give her for being late (even if for the first time). You wouldn't believe how hard that guy is on the poor girl, I mean, this one time, he- oh, "continue to the second part already" you say? I am only too happy to oblige.)

Rainbowdash was napping on a cloud (as per usual) which was nice for her, but she still gets warning notices from her boss about getting fired. She still doesn't get it. I mean, she doesn't bother anypony. All she does all day is sleep and...well, she wasn't sleeping anymore now that she was plummeting to her doom. Why is that you may ask? Let's ask the one who got away.
 
After Rainbow recovered from the not-so-gentle kick to the face, she scanned the sky for her assailant. "Scanning...Scanning..." she said, squinting her eyes towards the open skies...which is kinda stupid, I mean, you really should keep your eyes more unfocused to scan for movement, but I guess whatever works works.
 
And it did in this case. She caught a glimpse of a gray pegasus mare flying towards a mail thingy. This was moments before another "Work deficiency" notice landed on her face.
 
"I'm gunna catch that mare if it's the last thing I do," she whispered to herself.
 
In a flash (or as some might even call a "rainbow dash") she sped upwards toward the mailmare at impeccable speeds. She was on target with the still target. This'll be easier than Whoops! Overshot! No wait, the target disappeared!
 
Rainbow looked down to see the mare speeding away. "Not on my watch" she said while adjusting her bobby helmet. And just like that, she divebombed after her. The helmet didn't even have time to remember gravity!
 
As the two sped towards the ground, Rainbow became anxious. This mare seemed to know just how to piss her off and what she's gunna do. Now, she's calling her bluff to chase her down a steep dive like that. She knew rainbow couldn't pull up in time without the help of the sonic rainboom. She was goating her. "Well, of Raintastic's what you want, then Raintastic is what you'll get! Prepare to be dominated, you one eyed scottish sissy!"
 
The mare ejected her wings from her sides. Now rainbow was traveling at ramming speed in a collision course with what could be considered a wall. "Clever girl" is what she would have said if she thought about it. All she could really say was "OH SHIT OH SHIT OH SHI-"
 
The pure carnage of a pony on pony collision ran its course...actually she came out quite fine. The mare was up to her waist in Rainbow's throat, and she wasn't one to argue with what's given to her.
 
She gave the girl a hard swallow, bringing her down to her mid chest. Oh, how she loved the feeling of dry fur slipping down her throat.
 
"What the F*Rainbowdash!*ck is happening?!"
 
Well, that's a bit rude. Maybe another swallow will convince her to be more polite in the face of her hunter. (literally! You know how rude it is to have someone shouting inside of your face?)
 
"What did I do?!
 
Well, that was an easy one, she clearly...clearly...was flying in the right place at the wrong time. A crime punishable by death (exhibit A; Assassin's Creed)
 
"Why are yo-"
 
Oh, wait, what was she saying? Damn, her character was just developing in this story too.
 
With a final swallow, Rainbow sent the squirming mare to the depths of her stomach where she stretched out the pegasus's belly quite beautifully.
 
With a gasp for breath and a sigh of pleasure, Rainbow patted a hoof on her prize, feeling quite satisfied with today's hunt...oh, wait, she forgot to taunt.
 
"Hah! Thought you could outrun me, did ya?"

"Twilight, I don't feel very comfortable with this."
 
"Oh, come on, what's your problem?"
 
"I...I just don't like the idea that you're writing erotica fanfiction about me..."
 
"I think you're over thinking this. Rainbow likes it, I'm sure nopony will look at you differently because of it."
 
"I-it's not that. I...I don't want you to include me in your weird fantasies..."
 
"..."
 
"Um...Twilight?"
 
"Get out."
