AN: Chapter contains some degree of Relatively Gay Butt Stuff. You've been warned.

Being a tree is... awesome. Dash decided. It was like she was taking a nap all the time. But the sun on her leaves, the wind in her branches, her roots in the dirt, all of her growing suuuuuuper sloooooowly... that felt gooooooood. Like sex good, but relaxing. Like... like she'd thought a massage was supposed to work, before Rarity actually dragged her to the spa and Lotus had ended up pounding her back and doing no good and just complaining about her not relaxing.

Rainbow wasn't sure if this same sex-nap feeling would persist when she was actually moving around, but for now, she could just be and it was super-good. She could do it for hours. Had, in fact, since the sun came up and she'd woken from her pleasure-drunk sleep. Had she actually been asleep? Did trees sleep? Or had she just been so fucked-out she didn't remember any of it? She pondered on this for a minute before deciding she didn't really care and went back to chilling. And working on her body. Her second body- the first had formed of its own accord, almost identical to her original body with some leafy accoutrements and set up to seed other ponies- which she was making especially for Fluttershy. Fuck her up the ass and taunt her about it, would she? Rainbow would show her!

She was pulled from her contemplation of revenge by a vibration in the soil. She couldn't really see in color around herself, but she could feel... vibration of the ground, their shape in the air... even something she thought might be the life force of the things around her. It was shaped like a pony, the first that'd come near her. Her picture of them was a bit blurry, but the vibration felt heavy... too heavy for it to be any but one pony. He stopped and spoke, but she couldn't make out the words, only catching snips of what he said; however she was hearing, it wasn't normal pony ears. He turned around, and her leaves shivered a little, knowing what was about to happen and bracing for impact... only to feel a gentle tap on her bark.

And then the magic hit.

If Rainbow had a mouth, she would've moaned. It felt like he'd slapped her on the rump in the middle of plowing it, and she wished her body was done so she could raise her tail and get him to do just that. But she couldn't, so she listened, and heard in the tap a simple request: one apple, please. So she let the vibration travel to her branches and shake a single Zap-Apple (she was a Zap-Apple tree how cool was that!) free.

She felt the other set of hooves before noticing him noticing it. A light set... a mare, probably... tip-hoofing across her roots in a childish manner that came across as teasing to her senses. If these two were still here when her bodies finally fell in... fifteen minutes, maybe? She decided she'd do a test drive on them for teasing her so much while she couldn't do anything back. She watched them talk for a minute, and then discerned a crunching noise... he'd bitten into her fruit. Good. She wasn't quite sure what it would do; she had an impression of something but it was complicated and she couldn't quite make it out. She hoped he'd eat the whole thing, but he stopped after just a bite. A few seconds later, he sat down suddenly.

Rainbow could feel why; he'd planted himself right on her roots, and she could feel his heavy balls clench and churn, though he kept his stiffy in somehow, probably trying not to startle the mare. He was shaking and stuttering as he spoke, and the mare started getting a bit aggressive-sounding... Dash thought she might be getting the hang of understanding speech like this, but she still couldn't pick out individual words. There was a sudden movement in the air and her apple was in the mare's hoof, then Dash heard the crunch of fresh apple being eaten again. A snarky sounding comment from the mare cut off suddenly and she sat down too, also right on Rainbow's roots. She felt a gush of moisture, but then it stopped.

And the weight on that root grew. And grew. And grew. She 'watched' the mare get bigger than Big Mac, as big as that Troubleshoes pony AJ had told her about, and felt two gigantic nuts plop right onto her, follow by a monstrously heavy cock flopping out of its sheath and quickly lifting away as it grew erect. Dash ignored the panicked mutterings from the ponies about her roots, trying to piece together what it meant... it felt like the knowledge was just beyond her reach, like she should know it but was thinking too hard to remember it, as with many of her written tests. After a second, she gave it up, 'looking' at the ponies again... and as the much bigger stallion circled the now-smaller one aggressively, she saw their 'life force' and it just clicked.

And Rainbow wished she had hooves. So she could face-hoof. Just for that, Shy had earned extra bottom time. She was brought out of her exasperation by the taste of cum on her roots. Apparently the bigger stallion had now mounted the smaller and the insertion alone had made him squirt all over her roots. That was... that was actually pretty hot. Maybe it wasn't so bad after all. The cum tasted... different. She could still taste the resemblance, but at the same time it tasted better than normal. Probably her sense of taste down there was different, but it was very satisfying. Maybe you were supposed to water Dryads with cum and not water? Rainbow would have to ask Twilight.

She settled in 'watching' as best she could the two stallions go at it, 'listening' as the larger taunted the smaller as he mounted him right into the ground, milking his cock out all over her roots. After several minutes, it was starting to drive her crazy! She was horny as fuck but she couldn't do anything like this! She just had to... yes, if she... and then just push her way...

~

Only one of the two stallions had a mind to look over as a giant Zap Apple hit the ground, rolling over onto its side before splitting open at the urging of an angry hoof... from inside. He lost the thought as his Little Princess came again, squeezing 'her' tight ass around his monstrous shaft, a whinny wrung from his throat as he thrust harder and resisted his own orgasm again, wanting to really fill 'her' up with the biggest load he could. He fell back into a steady rhythm again as 'she' came down partway, managing to look up again... and almost lost his stride. Laying on the roots was a... copy of some kind. It looked just like his 'Little Princess' flopped over asleep. And then another Zap Apple came crashing down, something that looked like Rainbow Dash ripping her way out in seconds and shucking off the quickly shriveling fruit shell.

"Morning Mac, Morning Cheerilee!" Rainbow called as she stretched, "You guys seem pretty busy, so I'll get out of your manes; Flutters and I have... unfinished business."

Cheerilee slowed a bit more, confused, until a whinny of complaint from Big Mac reached his ears and he remembered what was important; filling his 'little filly' with his load. Still, he managed to listen when Rainbow spoke again.

"Oh, and feel free to have another one, if you want to do it the other way around, mmkay?" Rainbow caught a Zap Apple that seemed to fall of its own accord, setting it in a curve of the out-of-season tree's roots, "Just let Cheerilee take the first bite. Well, gotta jet!" Rainbow grabbed the clone of Big Mac and lifted into the sky, struggling to get altitude but managing it anyway, taking off in the direction of Fluttershy's cottage.

Cheerilee shrugged and got back to plowing 'Little' Mac, making him squeal and spurt what little was left in 'her' balls all over the ground and roots again.

"Wait wait wait." Twilight interrupted, looking up from her scroll, "What exactly do your Zap Apples do? I'm confused."

Rainbow buried her face in both hooves with a sigh, and Flutterbat answered for her in a slightly rougher tone than normal Fluttershy.

"Eaten alone, they make you intensely attracted to ponies of your own gender. Shared, they'll make sure the second pony matches the gender of the first, and impose feelings of submissiveness and dominance... in that order."

"TL;DR, Zap Apples Make You Gay."* Rainbow groaned from under her hooves.

Despite everything else, Fluttershy's routine hadn't really changed. It was lunchtime for her animal friends, and she distributed nuts, berries, kibble, and the occasional fish as appropriate while gently singing to herself. The trees of the Everfree knew some very strange songs, but she would leave the mystery of how they'd learned them to Twilight, once she could hear them. It was a catchy tune though, and Fluttershy couldn't help but shake her rump with the beat as she worked.

Once all the animals were fed, she trotted around to her back garden. The smaller plants didn't 'speak' like the trees did, or know things like the song she was singing, but she could still hear them, whether they were healthy or sick, asleep in the shade or growing in the sunlight. She leaned over to sniff at a carrot that felt a little pain in its leaves, trying to figure out whether it was a blight, a parasite, or had just been nibbled on... when a pony landed on her.

A hoof pressed into her neck, forcing her head to the ground, two heavy legs striking the earth behind her, a thick cockhead pressed up against her juicy asshole already. She hadn't seen it coming; her tree was on the other side of the house, and she hadn't even felt the vibration of their steps until just now. A complete sneak attack. Something crashed violently into her hedge, but she couldn't spare a thought as to what it could've been. Before she could even react, even, a very familiar baritone spoke into her ear.

"Singin' a song like that, swishing your plot around like ya ain't got a care in the world... a pony could get the wrong idea, Miss Fluttershy."

And then his freaking LOG of a cock sank itself into her other back garden, forcing itself inexorably into her slick passage with no respect for her comfort or pleasure, all the way to the balls without slowing or stopping. Had Fluttershy still been a pony, it would've been painful. Possibly injurious or even fatal. Instead, she opened her mouth and screamed... nopony heard it, though several animals thereabouts clamped their paws over their ears. Her pussy was gushing, her anus slicking itself further in preparation for a good hard fucking, and her own cock throbbed madly in the air, as hard as it could get and almost ready to spray the ground with cum for a cool breeze.

The pony behind her only whinnied a bit, shuffling his hindlegs, his monster cock twitching inside of Fluttershy's ass, making her pussy wink at thin air and her dick drool its pre into the dirt. When she ran out of air and could only pant, trying desperately to fill her lungs, Big Macintosh leaned down again to speak in her ear.

"They might think you're a filthy little ass-slut, Miss Fluttershy." Getting it in had been easy; getting it out took some effort, but he was up to the task, dragging several inches out, "They might think you like taking big, fat cocks up your tailhole." He got another few inches back, "That you like getting your ass filled with-" He shoved back in, his heavy balls slapping against her pussy, "CUM!"

For Fluttershy's sensitive dryad body, it was too much; the thick cock up her ass, the balls slapping her clit with perfect timing, mid-wink, the sudden, forceful treatment... and the fulfillment of a fantasy long-hidden in the depths of her mind, brought out only in private with the curtains drawn.

"Big MAAAAAAAAAAAAAAAC!" Fluttershy yelled, shaking and shuddering as she came, squirting his balls with her marecum and painting the ground white, her ass twisting and sucking at the cock plundering its depths, drawing only a grunt from the pony instead of getting his cum. He seemed to barely hold on, his hips giving mini-thrusts while her ass tried to milk him, whinnying nervously with his eyes crossed while he tried everything in his power to keep from filling her right then.

After almost five minutes, Fluttershy finally slumped, her hindlegs locking in place to keep that cock right where it was while the rest of her relaxed.

"Fuck that's nice..." Big Mac panted, "I can see why you love it so much, Fluttershy."

Click... click... click... ding!

Fluttershy smirked as she came down, but quickly hid it. She couldn't turn her head with the hoof still holding her, but she managed to sound sultry enough she didn't need to add the expression to go with her voice.

"C'mon Big Mac... you didn't give me your cum. Please cum in my ass! I need it! Cum and keep cumming until your empty and my belly's swollen with your seed! Fuck me good!" Fluttershy rocked her hips, her anus twisting in a milking motion around his dick.

"Oh fuck..." Big Mac grunted, moaning, but managed to pull back, beginning a quick thrusting motion, barely able to control himself.

"Oh yes." Fluttershy called, "That's good. Mfffff. Fuck me Big Mac! Fuck meeeeeee!"

He never noticed that she went limp right after, too concentrated on plundering her rear, his balls already starting to draw up as they readied themselves to release their load. A familiar flitting sound went similarly unnoticed, at least for all of the half-second before a familiar pointed canine prick split Big Mac's sphincter, burying the slick shaft all the way up to the swollen knot in a single stroke. The tight anus wrapped around his dick, his own super-sensitive asshole being suddenly ravaged... Big Mac exploded, releasing a sound that can only be described as "SKRONK!" as his balls pulsed and squirmed, firing load after load into the puppet he had pinned to the ground, his hips thrusting wildly as his greedy butthole milked the cock that had so suddenly speared him.

Neither of them noticed a wet 'CRACK!' noise.

"Hello Rainbow Dash." Flutterbat grinned into Big Dash's ear as it flicked, his eyes rolling from the continued orgasm, an angled press against his prostate milking a few more loads out before he was finally spent, standing on shaky legs, leather-bewinged Fluttershy clinging to his hind end and grinding herself gently in his ass, "Did you enjoy being on top for a few seconds?"

He didn't answer, his breath having left him entirely, lungs greedily sucking oxygen even while his ass continued to clench and pull at her buried shaft.

"Well, you feel eager at least. Your butt does seem sensitive-!" Fluttershy pulled back a few inches and then thrust in, battering his ring with her knot, but not pressing through, moaning in delight as it clenched harder, greedy for her cum; unseen, his cock released a spurt of watery jizz into the puppet it was still lodged in. "But I told you to fuck me in the pussy! I'm going to have to punish you for that..." She pulled a hoof back, balancing precariously on the raised red rump to give it a loud SMACK! Big Dash whinnied in pleasure, bucking his hips as he came again, asshole sucking, milking Fluttershy's dick for a few seconds before relenting.

"Hf... hf... nothing to say, Rainbow?" Fluttershy finally asked, grinding her knot against Big Dash's clenching sphincter, avoiding pressing his prostate again for the moment.

"Fffff-" Big Dash tried, finding his lips and tongue slowly, "Fffffuck- Fuck- Fuck my ass..." he managed to groan out, clenching a bit to encourage Fluttershy to ravage him.

"Well... my wish is your command." Fluttershy grinned, fangs flashing, yanking herself back and then stabbing forward, battering his ring with her knot, pressing it halfway in before drawing back, cooing and moaning at the tight ring squeezing her sensitive canine prick. She could barely balance, flapping her leathery wings to stay on, as she jackhammered Big Dash's Big Ass, both of them swaying with the force of her thrusts. She didn't let herself knot him just yet, letting the thick knob of flesh press at him, fill in halfway, only to yank it back out, the sensitive flesh throbbing with anticipation, expanding and contracting as it sensed a sensitive hole to lock itself into, to breed.

Big Dash could only grunt and groan at the harsh invasion, twisting his ass as much as possible, pumping his hips weakly, trying to coax Fluttershy's thick cum into his bowels, trying to get her to press that big fat knot through his ring and lock him like a bitch being bred. His half-limp, useless dick leaked a steady stream of watery semen into the puppet under him, only held in by his somehow rigid flare.

Finally, a lucky hump pushed her knot too far in, and his hungry hole closed behind it, locking Fluttershy into his spasming rear, his cock finally slipping free to dribble what little it could onto the ground as the thick bulge pressed his oversensitive prostate.

"yay!" Fluttershy squeaked around her fangs, startled at the sudden envelopment as her knot grew three sizes, locking her firmly into Big Dash's ass, heavy balls pulsing and twitching, filling the big red pony puppet with rope after rope of her cum, unleashing literal gallons of fake seed into Big Dash's body. She humped wildly, yanking her knot against his sphincter and driving it back over his prostate, her blood roaring in her ears. As she filled him, there was a moment of pressure, as the cum backed up, but it was gone almost before she noticed it, concentrating too hard on her frantic pumping to bother with wondering about it.

Fluttershy's long orgasm was tapering off, several minutes later, even while her copious seed continued to leak into the false stallion, when she noticed something flapping next to her. Something blue and leafy and rainbowy, giving her a slightly disgusted look.

"R-Rainbow?" Fluttershy started, half-worried through her continued orgasmic spasms, that she'd offended her friend somehow, that she'd maybe taken this too fast...

"Um, sorry Fluttershy. I really wanted to stay through that... believe me I wanted to stay! That was awesome. But..." Dash gestured at the puppet Fluttershy was still filling. The entirely limp puppet, with a large puddle of spunk growing underneath. Fluttershy stared at it for a moment, uncomprehending... and then something niggling at her through her connections finally struck her awareness and she paled.

"Oh ew ew ew ew!" Fluttershy yelped, yanking herself off the puppet... and doing more damage in the process, "Thats... ew ew!"

"Yyyyeah. I don't think I made it sturdy enough." Rainbow admitted sheepishly.

"That's okay Dash mine's... broken in half. Ew." Fluttershy replied, sharing Rainbow's disgusted look now. They were silent for a minute.

"So... um..." Dash tried, "What do we even do with them?"

"Well... I was planning to use old ones for mulch. They should be fully biodegradable, so..."

~

"And that's when you decided to carry them into Ponyville... without telling anypony... and use the carpenter's woodchipper... without telling him." Twilight asked flatly, giving Rainbow and Fluttershy a scathing look.

"I thought it would be more awkward to have to explain it and probably land us in jail!" Rainbow whined piteously.

"As opposed to getting caught and ending up in jail anyways."

"Well... yeah..." Dash replied, eyes glued to her hooves.

"It was going to come up sooner or later..." Fluttershy mumbled, and joined Dash in looking at her hooves like a scolded foal when Twilight turned her expression on Fluttershy instead.

"Right..." Twilight finally sighed, "I'll talk to the carpenter about using his woodchipper for this tomorrow. You two can go... do whatever. I'm going to go have a drink. A stiff one." A purple glow unlocked their cell doors without bothering with anything so mundane as a key, and the purple mare marched out the door to her chosen poison.

"See you later Jesus." Rainbow called to her new donkey non-friend, answered only by a snore as the two plant ponies plodded out into the night, "So..."

"Yes?" Fluttershy asked, hearing the prompting tone in Rainbow's voice.

"Do you have to do all six of us? Like directly? Can I...?" Rainbow trailed off into mumbles, blushing. Fluttershy tittered.

"Of course, Rainbow. If you can talk Applejack into it, you can do her. If you know what I mean." Flutterbat blushed a little, showing her fangs cutely.

"W-Who said anything about AJ?" Rainbow demanded in a stutter, only blushing harder when Fluttershy just raised an eyebrow at her, dropping it.

"Well, if you'll excuse me Dash, I still have some animals to feed tonight, especially if I want to make my spa date with Rarity tomorrow."

"The spa? In these? Well, I suppose it's easier to wash them than replace them, unlike most of my clothes..." Dash admitted, paused, and then grinned, "Oh, with Rarity, huh? Wonder what Aloe and Lotus will think of that!" Rainbow trailed off into laughter, Fluttershy just smiling a bit worriedly as she turned aside towards her home, waving at Dash as they parted ways.

Author's Note

*I was going to link this really amusing SNL skit entitled "The Homocitrus Agenda" here, but apparently someone got whiny about the copyright and burned it off the internet. You can blame them for two weeks of being annoyed about that rather than working on this.

FYI, the Flutterclone was broken in half when the Mac-Clone hit it too hard and the Mac-Clone had a critical structural failure because the Fluttercum wasn't funneled right and basically popped his stomach open. You can expect more humorous clone deaths in the future, though I don't have any more planned during sex. There is a why, and Twilight will figure it out eventually, but it's not really relevant to the plot.

Next chapter, um, whenever... I'm not actually too confident in that last scene, I feel like I rushed it.
