"Well, if you insist." Fluttershy mumbles in her usual demure manner, "Here." A few peaches drop from the tree, right onto Fluttershy's waiting wings and then into an indent in her roots, "The more dryad magic you have in you, the quicker you'll grow big enough to come back out again. If you eat at least three, it should only be a day or two instead of a week." Fluttershy glances over at Twilight, who had withdrawn a notepad and begun scribbling, and then turns toward her house.

"I'm going to leave this me upstairs, the other me will be right back." Fluttershy trotted off, "Remember, at least three."

Rainbow had bitten into the first before she stopped speaking, her moan at the taste stopping her from gobbling them all at once as she'd intended. The juice runs down her face for a moment before she slurps it up and slowly savors the rest of the peach, a little at a time.

"That good, Rainbow?" Twilight asks from the safety of her mask.

"Ohhhh yeah. These are delicious." She glanced at Twilight and snickered, "Miss biohazard."

"Just eat your fruit Rainbow. And tell me how you feel."

"What I feel is fucking horny. It's getting worse, but after spending most of the day clopping I think I'm not feeling it as much." Rainbow picked up a second one and bit into it, speaking as she chewed, "An' my butt feelsh all tingly for shome reashon."

"Try swallowing before you talk, Dash." Twilight scolded.

"That's what she said!"

"Uuuuuuugh."

"But seriously, we need to get Pinkie to make pies with these things. They're really awesome." Rainbow finished the second peach as soon as she was done commenting. She was reaching for a third when she suddenly stopped, wings snapping open out of her control. "Oh no. No no no no no-!"

"What's the matter Dash, is it doing something else? Does it hurt? Do I need to get you to the hospital? Cast a dispel on you?" Twilight panicked, tensing to rush to her friend just in case.

"No. No. It's not... it's not that. I don't... I can't..." Frustrated tears fell from Rainbow's eyes as her tail involuntarily lifted, her forelegs bending to put her into a presenting position almost against her will as she locked eyes with the last peach, "I gotta eat the last one but I can't, I can resist for now, but if that last ones does what I think I won't be able to and then I'll..."

"Then you'll what? You'll what, Rainbow?" Twilight stood, hesitantly approaching her friend.

"Submit." Both sets of eyes snapped to the sexy, randy version of Fluttershy, and a moan rang out from Rainbow as she fell entirely onto her face, hips thrusting against the air, "When I licked Rainbow's ass yesterday, she promised me all kinds of things if I'd just keep doing it." Noting Rainbow's eyes clenched shut, Fluttershy moved over to her, leaning her face in close and giving her friend a kiss on the cheek.

"It's okay, Rainbow. Tell me why this scares you." Fluttershy whispered gently into her ear. Rainbow didn't answer, still panting and clenching her eyes shut. "Is it your reputation for being a tough, take-charge pony? Or are you just scared of giving all of yourself to someone else?" Rainbow nodded to the second, a whine coming from deep in her throat.

"It's okay Rainbow. It's fine. You knew what was going to happen here, didn't you?" Another nod, "You knew I was going to go right for your ass again. Make you love it. Make you mine. Didn't you?" Fluttershy received another whine in answer, Rainbows hips thrusting of their own volition against the breeze. "Do you trust me, Rainbow Dash? Do you think I'd ever hurt you while you can't resist? Make you promise things you would hate yourself for later?"

Rainbow let her eyes open, looking up at Fluttershy, and slowly shook her head.

"Then will you eat your last peach? You'll enjoy this ever so much more if you do." A yellow wing lifted the peach to Rainbow's mouth. Hesitantly, she bit into it, moaning at the flavor, moaning in lust, and most of all, at the sensation of her tight backdoor clenching and grasping in search of a thick cock to fill it up.

"Good girl." Rainbow moaned around the remainder of the peach at Fluttershy's praise, quickly swallowing before any could be lost, "You're such a good girl, Rainbow." Fluttershy winked at Twilight in her front row seat, barely three feet away, and walked around to Rainbow's raised rump.

"Fl-Flutters- I can't..." Rainbow mumbled, then yelped as Fluttershy blew gently across her dock, before descending into nonsense mumbles.

"Mmhmhm. Your asshole looks so greedy, Rainbow. I could get you to do anything if I promised to shove my cock in there when you were done, couldn't I?" Fluttershy asked, her mouth almost right on Rainbow's tailhole, warm breath washing over her dock and furiously winking pussy, "Would you enjoy that, Dash? Promising to serve my every whim for the rest of your days? Being forced to commit every perverted, depraved kink known to ponykind, one after another?" Fluttershy leaned down further, just barely letting the tip of her tongue touch Rainbow's taint, sending Rainbow's holes clenching and writhing as she balanced on the edge of an orgasm.

"YES! YES! I'D LOVE IT!" Rainbow shouted against the ground, forcing out the words desperately, "I'LL DO EVERYTHING YOU EVER SAY, JUST FUCK MY ASS UNTIL I NEVER STOP FEELING YOUR COCK AND MY STOMACH IS FULL OF CUM!"

"Can you imagine that Rainbow?" Fluttershy continued, her lips brushing teasingly against Rainbow's nethers, her head bobbing a little so everything got that tiny, teasing stimulation, "Feeling me in you when you go to market? Standing in line while the pony behind you knows you're feeling me in your ass the whole time? You know, I think I might even figure out a way so I can actually be in your ass all the time? Send you walking around town with me buried in your ass, cumming every time you get off on being watched like that, filling you until you leave a white trail and your belly is dragging the ground."

"F-F-F-FLUTTERSHY~!" Rainbow wailed, "PLEASE STOP TEASING ME AND PUT IT-UGH!" With a speed that would've impressed Dash if she'd been in her right mind, Fluttershy had mounted her flying, shoving her wooded dick all the way down to the knot with no warning at all before setting her forehooves down on the base of Rainbow's wings and her hindhooves on the ground.

"Mmmmff." Fluttershy bit her lip as she moaned, "So that's how it feels. Mmmm, you're so hot and, ah, tight inside Rainbow. Your ass is delicious. Ah! It feels like you're trying to milk me."

Rainbow Dash had frozen under Fluttershy's assault (with the notable exception of her kegels,) mouth hanging open in a silent scream, eyes rolling wildly in their sockets.

"Bad girl." SMACK!

The slap on Rainbow's ass broke her paralysis, her lungs gulping for air, body heaving while her nethers clenched, spraying her marecum all over the dirt and Fluttershy's roots.

"I'll give you my cum when I say so, and not before." Rainbow's eyes crossed again as Fluttershy sloooowly drug her dick out, almost feeling like it was taking all of her insides with it, and she burbled unintelligible noises again until it thrust back in, stealing her breath away again and sending another spray of her juices to the ground. "You're such a dirty anal slut, aren't you Rainbow? Both times I've shoved it in, you've cum. Not even a hoof for your pussy and you squirt all over for a cock in your ass."

"Yeeeeeesssssss." Rainbow managed, "Sluuuuuut." Withdraw, thrust. Hot liquid sliding against her walls, dripping deeper than Fluttershy could penetrate, searing her bowels with pleasure. Withdraw, thrust. Hard, hot, rubbing, the knot pushing against her tortured sphincter, demanding entry. She whined for it, but it withdrew. She came again as it pressed back in.

"Ooh, three, unf, pushes this time. Getting used to it? Or just getting too worn out?" Fluttershy grunts as she shoves in again, feeling Rainbow's tight backdoor squeeze and churn, trying its best to drain her dry while her puffy butthole squeezed every inch like it wanted to never let go, "Maybe I can help. Ah!"

Rainbow's ears perked, listening even though her brain couldn't really process much besides the pleasure at the moment.

"You want my orders, don't you? Want to do everything I say?" Fluttershy humped Dash harder, still careful not to knot her yet, drawing her thick wooden staff out and shoving it back in just short of doing it, pressing the swelling lock against her tight hole every time, "Well, here's your first order; every body you build has to have the most sensitive ass you can make. I want to be able to slap your rump and make you cum from a standing start. I want you to squirt all over my chin the second my tongue touches your ring. I want one touch on your prostate to make you empty your balls all over the ground every single time! I want you so addicted to a cock in your ass that you come up to one of us every day begging for at least one assfuck!"

"Mares don't have prostates. Or balls." Twilight mumbles as she takes notes (and sketches) and tries to masturbate without being obvious about it. Fluttershy giggles, giving her a sly look only slightly ruined by her haggard panting before turning her attention back to Rainbow Dash and making up for her lapse with a particularly sharp hump. She needn't have bothered.

Rainbow had entered some kind of weird sex-nirvana where she could only mumble and moan, too out of breath to scream even as she came until the orgasms blended together into a single neverending sea of pleasure... but her empty mind was clear. With no thoughts of her own, Fluttershy's words almost felt like her own idea, pouring into her empty brain and engraving themselves as unbreakable rules. Then her voice came again, adding more.

"You like that, don't you Rainbow? Getting orders while I pound you raw? Well, here's another." Fluttershy sped up, now officially slamfucking Rainbow, only just barely managing to hold back enough to not knot her, the bulb now fully swollen and ready to blow, just waiting for penetration. "I want you to give your first body a big. Thick. Meaty. Cock. I don't care what else it has, just as long as it has a cock big enough to feel like it's splitting me in half. When it drops, it's going to come find me, wherever I am. And then you're going to push me to the ground, and shove it right up my pussy. No matter who's around, no matter what's happening, you're going to find me, and you're going to fuck me as soon as you can. Got it?" Fluttershy leaned down, taking a hold of Rainbow's wing-shank and clamping her teeth down hard enough to cause pain, grinding her hooves into the bases and finally sinking her knot into Rainbow's tight asshole, distending the puffy, tortured hole for several seconds before it clenches back down, trapping her inside.

Rainbow sucked in a huge gasp of air, eyes focusing back to center as her pupils contracted to points, only to lift into her skull once more as she let out an ear-piercing wail of pleasure, filly-juices soaking the ground behind her. Fluttershy moaning into her wing as her teeth relaxed, hooves grinding into their muscle bases as she lifted herself back up. The knot pushing against pleasurable places Rainbow Dash had no idea were there while the tip began moving, moving, squirting and squirting, filling her ass with burning, lustful cum. Then it pushed further, twisting and turning up her intestines, forcing itself past places it had no right going until it emerged into her stomach. It paused there, dumping spurt after spurt into her belly as it poked around for the exit, the cum bringing pleasure even there, before it finally found its way out into her throat, squeezing itself through into her esophagus and pushing past her air-passage, finally cutting off her scream as it bulged out her throat and passed her lips into open air.

Twilight, meanwhile, was managing to observe even though she was about to start 'watering' a particularly smooth bit of Fluttershy's roots. The gasp had given her warning enough to conjure some noise-cancelling earmuffs, but she'd flinched when the plastic of her mask had cracked. She gasped herself when the head emerged from Rainbow's mouth, waving about in the air as though searching for something... and then turning to her. She had no chance to react as it dove for her mouth... only to bounce off of her intact mask. Seeming offended, the tendril knocked her earmuffs off and reared up over her head, thoroughly spritzing her with plant-jizz, all in her mane and over her back, before pulling back down Rainbow's throat, finally letting her suck in a breath of air.

"Twilight! Get ready!" Fluttershy called, bringing Twilight out of her confused and lustful stupor. The dryad gently pulled herself away from the insensate pony beneath her, still shuddering with orgasms as the seed rooted itself in Rainbow's stomach, giving up on finding a better chamber, the tendrils that would soon become roots giving her clit a goodbye caress as the seed-sheath receded into Fluttershy's puppet. "She's going to move quick!"

Rainbow's wings were already lifting her into the air. Twilight grumbled, lifting her winking, unsatisfied pussy from Fluttershy's root and bringing another sly smirk from said pony as she lifted into the air herself, a bit shakily. Rainbow spun around lazily for a moment, legs twitching in the air, dribbling drool into the dirt with one end and pussy-juice with the other. Finally, she stopped facing a directly and began to slowly drift in that direction. A slow drift for Rainbow Dash, anyway, which was about cruising speed for Twilight and Fluttershy. They moved as the crow flies, Twilight leaving her own trail in the dirt alongside, headed diagonally past ponyville's edge, towards-

"Sweet Apple Acres? Twilight, could you clear the way ahead? I don't want Apple Bloom stumbling on us, at least." Fluttershy asked. Twilight nodded, charging her horn... and fizzling her first cast into harmless, useless sparks. Groaning in embarrassment at the magically equivalent of premature ejaculation, she tried again, teleporting to the edge of their view in the direction of Applejack's farm... and appearing almost on top of Applejack's head, perhaps a dozen feet past the front gate.

"Twilight? What's goin'... on?" Applejack raised an eyebrow as she felt something wet hit her flank, tracing it's trajectory back to- Applejack's eyebrow tried to leave her face as her expression turned flat at being femjizzed on.

"Sorry! Where's Apple Bloom?" The other eyebrow joined the first, and then both sank as Applejack's eyes narrowed, "No no! Not like that! Rainbow's coming! She's planted! Planting! She's looking for a place to plant herself!"

"Well, she should still be at school at this hour." Applejack finally replied, not really letting up her expression, "Rainbow's planning on doing what on our farm now?" Applejack asked, glancing in the distance to see Rainbow slowly approaching, frowning slightly at seeing no consciousness in Rainbow's eyes.

"Planting herself. Fluttershy seeded her."

"And the mask? And the... whatever it is all over you?"

"Um... long story. Gotta go!" Twilight flew on ahead as Rainbow and Fluttershy approached.

"Hi Applejack. Don't mind us~" Fluttershy singsonged as she flew by, shadowing Rainbow further into the orchard. Straightening her hat, Applejack trotted after them, muttering under her breath and glancing disgustedly at the trail she was following.

~~~

Twilight braked to a stop as she reached a particular part of the orchard, then giggled to herself. She turned around and spread her forelegs in a 'ta-da!' gesture as Fluttershy got close enough to see. Fluttershy looked ahead to what Twilight was indicating and facehoof'd.

"I suppose we should've guessed." Fluttershy admitted, "I wonder if she'll like how she tastes as cider."

Two hysterically giggling ponies followed Rainbow into the dark trunks, weaving around them a bit as Rainbow slowed before finally coming to a stop. The spot seemed to be of no particularly significance other than that it was just big enough for another tree to spread its roots between the others, with a clear patch of sky for its leaves. She drooped to the ground, slowly coming to rest on her hooves, wobbling for a moment before she finally sat down. Rainbow managed a single squeaky cry before the tendril broke through her lips again, cutting off her voice as her body quaked with pleasure, her roots sinking themselves into rich Sweet Apple Acres soil. One slid up into her pussy almost gently, just before she was lifted into the air, stormcloud-dark bark growing around her quivering body and up into the sky, branching out, leafing itself, and finally sprouting its electric blue electrical blossoms with their signature popping sound.

"It's beautiful." Fluttershy stated, tears in her eyes. Twilight just nodded agreement at the blooming Zap Apple tree among it's barren brethren. They both ignored the timberwolves loping in to arrange themselves around the roots protectively.

"Well that's nice and all, but what am I supposed to tell my family about the timberwolves? Much less the Zap Apple tree blooming out of season." Applejack asked, startling both of them, "And Twilight, Rainbow I kind of understand, but please stop dripping in public on my farm."

"It's not her fault, Applejack. Rainbow's seed sort of, well..." Fluttershy gestured to the lighter, matted, sticky bits all over Twilight's back and mane. The timberwolves, receiving some unseen signal, simply got up and loped off back toward the forest.

"Oh. Well. I guess it ain't a problem. For the moment. They probably won't even notice the tree 'less they start howlin' anyway." AJ grimaced at Rainbow Dash's tree, "Now I'll gotta worry about finding ten Rainbows in my trees instead of one, won't I?"

"Um, probably. Anyway, I'm sure you'll take good care of Rainbow, but we should probably go. Twilight?"

"Huh? Oh, right. The stuff. I..." Twilight shook her head as though to get rid of a fly, panting loudly, "I should head home and take care of it."

"No. You'll probably make yourself bleed if you try to do it yourself after direct exposure. You need help." Fluttershy asserted, herding Twilight away from the Zap Apple orchard, "Just come back to my cottage and we'll sort it out."

"But... but I can't yet. Not... not ready, haven't studied enough. You promised." Twilight tried, nevertheless letting herself be herded.

"Oh no! Not that. It takes a few hours to grow back anyway. But I've got a perfectly fine body that can help you lying right in my bed; I'll put this one down by the tree and we'll take care of it, okay? No! Don't take your mask off or we'll be doing it right here in the orchard." Fluttershy scolded, slapping a hoof away from the strap.

"Iunno Fluttershy. Kind of in the mood for intercourse." Twilight explained, swaying a bit drunkenly, tongue not cooperating well with anything besides being laid on a sweet muff or a hard shaft.

"Oh trust me, I've got that handled." Fluttershy grinned, continuing to urge Twilight towards her cottage, steering her out the main gate under Applejack's watchful, skeptical eye.

"Really? D'you got a Princess Pleaser? That's my favorite."

"Oh, I think it'll please a Princess."

Their voices faded as they turned off away from the road, skirting town toward Fluttershy's. Applejack stared after them from the gate for a few minutes, then sighed, fanning herself with her hat.

"Gettin' a mite sexy 'round here. Well, maybe year-round Zap Apple Jam will be worth having Raining Rainbows." Applejack chuckled at her own joke, trotting back towards the barn to finish the day's work.

Nopony ever did explain to her about the properties of a Dryad's fruit.

Author's Note

Was going to include Fluttershy helping Twilight in this chapter, but that point was just too good not to end on. Next time: on whether Fluttershy can please a princess and on what happens when an Apple shares an apple with no idea of its effects.

Also, in case you missed it, there's now an omake in gdocs, linked in the AN of the previous chapter. Do check it out. I will also be updating the fetish list in the summary momentarily.
