A little help from Fluttershy

Twilight checked her watch: 12:45. Running early. She thought. Perfect.

Having fled the beach before Rainbow and Pinkie talked her out of her swimsuit, Twilight had plenty of time to take a long (and teeth-grittingly cold) shower to calm herself down. She had astutely ignored her extra anatomy as she put on an appropriately conservative skirt and blouse, and kept her mind on her schedule.

She considered staying in, but ultimately decided against it. It'd be best to be social and friendly, just like she'd planned, so nobody would know. After all, any deviation from her schedule would be an emergency, and that would get entirely too much attention, and then she'd have to make some very awkward explainations.

Besides, Twilight thought as she walked up to Fluttershy's cottage, it's not like things could get any worse than what I've already been through.

Twilight adjusted the box of cookies beneath her arm, and knocked on the door.

“Oh! Sorry!” Fluttershy's voice came from the other side, “Hold on! Just a second! Please!”

A few moments later, the door swung open. Fluttershy peeked around the edge of the door- her hair wrapped up in a fluffy white towel. “Oh, it's you.” she said, and blinked, “I mean that in a good way, though! I'm so sorry, I'm just a bit flustered, I almost forgot you were coming over. Please, come in!”

“That's alright, Fluttershy.” Twilight smiled as she entered Fluttershy's cozy cottage. It was just as warm as welcoming as the last time she'd visited- even if it still had the lingering, earthy scent of kept animals. You get used to it. Twilight reminded herself. “Honestly, you wouldn't believe the kind of day I've been-” She trailed off as she turned to look at her shy friend. “-having.” Twilight managed to complete the sentence, despite the sudden dryness of her mouth.

Fluttershy shut the door, leaning against it slightly. To match the fluffy white towel around her hair, she had on an equally fluffy robe. Twilight couldn't help but notice how the robe didn't fit Fluttershy well- or rather, perhaps it fit her too well. The terrycloth robe was tied fairly loosely, revealing a scandalous 'v' of Fluttershy's pale skin, nearly to her belly button. On top of that, the bathrobe didn't reach very far downwards, putting Fluttershy's long, willowy legs on display.

“Sorry!” Fluttershy apologized, yet again, “I had to muck out the pigsty this morning, and it took longer than I expected, and then you showed up earlier than I expected, so I'm just now getting out of the shower. I'm so sorry.”

“Oh no, Fluttershy! Don't feel bad. You look great.” More than you know. Twilight thought, and bit the inside of her cheek again.

“Oh, you don't have to be so nice. I know I'm a mess.” Fluttershy said, “I'm so, so, sorry- this whole morning's just been a disaster. Well, um, maybe not a disaster, but, um, maybe something a little bit less than that.”

“It's alright, Fluttershy.” Twilight forced a smile and patted her friend on the shoulder. “You're not the only one having a, uh, hard time of things right now.”

Why did I say that? Twilight thought.

“Oh no!” Fluttershy squeaked, “I'm so sorry! Here I am going on about my silly problems, and you've got it so much worse than I do!” Fluttershy lunged for Twilight, pulling her into a hug. “What happened? Is everything okay?”

“Fine. Just fine.” Twilight said. “It's just been a...rough day, is all.” she relaxed into the hug, slumping her shoulders as she felt just a little of the day's stress fade away.

“Uh. Twilight?” Fluttershy said, “what's that?”

“What's what?” Twilight bit the inside of her cheek once she realized the inevitable result of having a scantily-clad former model pressing herself to her body.

“Um. I. Don't. Know.” Fluttershy lied. Badly.

“It's nothing!” Twilight was an even worse liar than Fluttershy.

The two stared at each other for about an eon or two.

“It's something.” Twilight said.

“What...kind of something?”

“I don't exactly know, myself.” Twilight sat down on Fluttershy's couch and pulled her legs up beneath her, doing her best to both
conceal and ignore the monument to anatomy pushing upwards from her lap. “Or, uh, I do know. I know what, I mean. I just don't know why.”

“You didn't...always have one, did you? I mean, uh, I never really...checked.”

“No!” Twilight said, “I just woke up this morning, and it was...there.”

“Oh, okay.” Fluttershy said. “You're not...um...a frog, are you?”

Twilight blinked. “Of all things, that's what you ask about?”

“Oh! Sorry!” Fluttershy cringed back into her corner of the couch. “It's just that, um, certain amphibians and fish will change their sex, depending on factors like population demographics and water temperature and stuff.”

“Of course!” Twilight said, and smacked herself in the forehead. “That makes perfect sense! I don't know why I didn't think of it earlier?”

“Maybe you were, um, distracted.” Fluttershy looked down towards Twilight's lap.

“It is hard.” Twilight said.

“Oh my,” said Fluttershy.

Twilight felt her cheeks go suddenly, thoroughly warm. “I mean! It's hard to think! I'm just trying to go around my day to day
business, and then...” she trailed off. The two young women stared at each other for what felt like another few million years.

“So.” Fluttershy broke the awkward silence. “Does it work?”

“Um. Yes. At least, from...solitary study, that's the impression I got.” Twilight forced herself to speak.

“Can I see?”

“What?” Twilight sputtered.

“Oh! I'm sorry! It's just, um, this is kind of a once in a lifetime opportunity.” Fluttershy leaned closer, and her robe fell open,
revealing an all-too-tempting swath of bare skin. “I'm...just trying to help. I mean, it must be hard.”

“Fluttershy!”

“For you! It must be hard for you!” Fluttershy squeaked, looking up at Twilight's face. “It...just came out of nowhere, didn't it? And now I bet you have to deal with, um...urges, don't you?”

“I don't know if I'd call them urges, per se.” Twilight didn't look down Fluttershy's open robe. Not for very long, at least. “I mean, I can control myself. It's just...it's a little scary. Well, it's a lot scary.” Twilight said with a pained sigh. “I mean, random magical mutation of this sort is absolutely unprecedented- I've never read anything about it before.”

“Oh, Twilight.” Fluttershy's lip quavered, and she scooted closer on the couch. She laid a gentle hand on Twilight's knee, and smiled up at her. “I'm sure everything's going to be okay. You're still you, even if you're having a hard- um, I mean, a difficult time right now. I just want you to know I'm here for you, and I'll do anything to help you.” Fluttershy scooted closer. She smelled of flowery body wash.

“Anything?”

“Anything.” Fluttershy said, and dipped her hand beneath Twilight's skirt. It didn't take her long to find the telltale bulge beneath the fabric. Twilight sucked in a giddy breath as she felt soft, slim fingers close around her cock.

“Oh!” Twilight blurted.

“Should I stop?” Concern showed in Fluttershy's eyes.

“Please.” Twilight bit the inside of her cheek again. “Don't stop.”

“Okay.” Fluttershy said in a low voice. “Just...lean back.”

Twilight obliged, practically melting into the couch. Fluttershy leaned over her. Her robe was completely open now, any pretense of modesty abandoned. The fluffy white terrycloth only served to highlight the naked flesh beneath, like the frame around a painting. A nude portrait, to be precise.

Fluttershy wasted little time in lifting Twilight's skirt up, pulling her panties down, and soon Twilight's cock flopped comically out into the open.

“Oh wow.” Fluttershy said. Her cheeks went scarlet, but she kept her eyes locked on Twilight's rigid member. “That's...that's there, alright.” She slid her fingers upwards, circling her gentle fingertips around the head of Twilight's dick.

“Oh!” Twilight tensed, back arching.

“Oh!” Fluttershy recoiled. “I'm sorry!” she squeaked. “I didn't hurt you, did I?”

“N-n-no.” Twilight managed as she gave a shuddery, nervous laugh. “The opposite, really.”

“Oh.” Fluttershy said, smiling sweetly up at Twilight. “In that case...” she pulled the towel off of her head, revealing her still-damp pink hair. Twilight shivered as she felt the ends of Fluttershy's hair teasing over her thighs as Fluttershy's head went downward.

“Fluttershy, are you- ah!”

With one hand wrapped around the base of Twilight's cock, Fluttershy guided it to her lips. Twilight moaned softly as she felt her friend take her into her mouth. Twilight held her breath, foring herself to stay still as she reveled in the sensation of Flutterhsy's moist lips and tongue on her.

Twilight watched Fluttershy's pink haired head bob up and down on her; surprisingly eager for someone so shy. Each pass of Fluttershy's tongue made Twilight squirm and moan as her friend pleasured her.

Fluttershy finally went up for breath, pulling away from Twilight.

“That was...that was amazing.” Twilight murmured, still panting.

“That was the warmup.” Fluttershy said.

“What are you-”

“Sssh.” Fluttershy held a finger to Twilight's lips. “Just let me take care of you, okay?”

Twilight only nodded.

Fluttershy stood and let her robe fall to the floor. Twilight bit at the inside of her cheek, looking at her friend in an entirely new light. Fluttershy was tall and slender, though she still had a certain softness to her in her hips and bust. Twilight wet her lips without knowing it, enthralled by the sight.

Fluttershy climbed onto the couch, parting her legs to straddle Twilight.

Struck dumb by the vision before her, Twilight could only watch in eager anticipation as Fluttershy lowered herself, guiding Twilight's still-hard, spit-slicked member into her waiting pussy.

“Oh!” Fluttershy squinted her eyes shut. “You're big!”

“Are you okay?” Twilight said, “You don't have to do this-”

“But...I want to.” Fluttershy said, a slightly mad quaver slipping into her voice. “But, um-” she suddenly switched back to her usual, shy tone. “Do you want to?”

“Oh please yes.” Twilight blurted.

“Okay, good.” Fluttershy leaned down to kiss Twilight's forehead. “Then don't worry about me. I like it rough.”

And with that, Fluttershy lowered her hips the rest of the way, encasing Twilight's prick in her tight, warm pussy. Fluttershy moaned, squinting her eyes shut as she got used to the feeling of Twilight inside of her. Soon, Fluttershy began to move, each roll of her hips growing faster and more urgent than the last.

Twilight pushed her hips up to meet Fluttershy, but her friend just kept pumping herself up and down, riding Twilight hard enough
to make the couch they laid on tremble precariously. Fluttershy threw her head back in lusty pleasure, and her perfectly-sized breasts jiggled enticingly with each grind of her hips.

“Fuck! Yes!” Fluttershy's voice echoed off the walls of her cottage. “Fuck me! Harder!” She grabbed hold of Twilight's blouse and tore it open, sending broken buttons scattering around her living room.

Acting on instincts she didn't know she had, Twilight sat upwards, and pushed Fluttershy down to her back. Fluttershy moaned, and spread her legs obligingly.

“C'mon, stud. Fuck my tight little pussy!” she squealed, mad with lust.

Where'd she learn to talk like that? Thought a more rational part of Twilight's mind. The fleeting thought was forgotten, however, as she urged herself on. She grabbed hold of one of Fluttershy's legs and balanced it on her shoulder as she leaned into her thrusts, putting as much force behind them as she could.

Fluttershy squealed, “Oh! Oh shit, that's it, right there, oh, fuck! Right there, oh shit you fucking stallion I'm gonna- ah!” Her whole body tensed suddenly, every muscle going taut as a guitar string before she came, shivering and twitching in delighted ecstasy.

Twilight gasped as Fluttershy came around her- as her pink haired friend writhed blissfully, Twilight held tighter to Fluttershy's leg, but even still the tangle of limbs was too much, as Twilight's cock slipped out of Fluttershy's quivering pussy in the fray.

Twilight collapsed back onto the pouch, panting, and watched Fluttershy shiver a few last times as her orgasm subsided. Twilight help but feel a sense of peverse accomplishment, to see one of her best friends naked, sweaty, and thoroughly satisfied.

Finally, Fluttershy opened her eyes, consciousness returning to her. “Um. Wow. That was...nice. Really nice.”

“Yeah.” Twilight said, smiling despite herself. “Was that, um...your first, uh...y'know...”

“My first time with a girl.” Fluttershy said. “Even if you had the...” her eyes fell to Twilight's lap. “Oh! You didn't-”

“It's okay.”

“No it isn't! That was the whole point, wasn't it?” And with a sly smile, Fluttershy laid down on her belly, eagerly taking Twilight into her mouth again. Sensitive as she was from earlier exertions, it took little more than a few passes of Fluttershy's tongue across the head of her cock to push her over the edge. Twilight grit her teeth and let herself go, spurting a sticky load into a surprised Fluttershy's mouth. The pink haired woman made a surprised squeak, and then leaned back, and Twilight spilled the rest all over herself.

“Oh, I'm sorry, let me get that...” Fluttershy grabbed her robe from the floor and (after daintily wiping the corner of her mouth) set about cleaning up. “Did you, um...have a good time?” she asked, cheeks still flushed happily. “I didn't get, uh...carried away, did I?”

“No, no, it was...you were...wow.” Twilight breathed in deeply. “It's...well, I guess it's a silver lining for this whole 'unexpected penis,' thing.”

“Well, that's good.” Fluttershy cuddled up against Twilight, and kissed her cheek chastely. “I just hope this doesn't make things, um, weird, you know? Between us, that is. I mean, we're just, um...experimenting, right?”

“Fluttershy!” Twilight sat upright in a bolt. “That's it!”

“What is?”

“I've been trying to ignore this all day, and it hasn't gotten me anywhere. To truly understand this-” Twilight pulled in a breath and
started over. “To truly understand my penis, we need to set up an experiment, under controlled conditions.”

“Like, a sexy experiment?”

“Not really, no.”

“Aw.”

Twilight bit her lower lip. “But that doesn't mean we couldn't, um, celebrate, once the results are in?”

“Yay.”
