You Girls Gotta See This!

Two weeks had passed since six friends graduated from Canterlot High, and they were determined to make the most of the last summer before college. The third sleepover of the summer, at the Apple family's house, was well underway.

"Where'd Fluttershy run off to?"

Applejack, Pinkie Pie, Rarity, Rainbow Dash, Sunset Shimmer, and Princess Twilight Sparkle sat around Applejack's bedroom, playing poker and snacking. The other Twilight had been invited to the sleepover, but had other plans.

"I dunno, bathroom maybe?" Sunset suggested with a shrug.

"For ten minutes?" Twilight wondered as she rearranged her hand.

"Well, we did eat all that pizza earlier," Rainbow pointed out. "I mean, Fluttershy usually eats like a bird, but she was really puttin' it away!"

"As if you're one to talk, Rainbow Dash," Rarity scoffed.

"Well, I need to stretch anyway, so I'll go check on her," Sunset said. She got up and headed to the door. "Keep your eyes off my cards!"

* * * * *

The bathroom door was ajar and the lights were off. Sunset frowned. "Huh. Is she raiding the kitchen?"

Sunset padded down the stairs, through the living room, and into the kitchen. The lights were on, but the room was empty. Her brow furrowing in confusion, she began prowling around the Apple house, searching for her wayward friend. There was no sign of her anywhere downstairs. She briefly, quietly checked Granny Smith's room—the only member of the Apple family whose room was downstairs—but she wasn't there either.

"Did she go outside, maybe?" Sunset wondered, brow furrowing. She shook her head dismissively. "No...Fluttershy wouldn't have gone wandering around dressed like that." It was a very warm, very muggy early summer night, and none of the girls were wearing pajamas—not even Twilight. They were all sitting around in oversized T-shirts and panties.

Shaking her head, Sunset headed back upstairs. "Maybe she's..."

A sound caught her attention, and she trailed off, straining her ears. She crept down the hall, past Applejack's room, toward the largest bedroom at the end of the hall—the master bedroom, which Big Macintosh had moved into a few years after their parents' death. The door wasn't closed all the way; the reading lamp was on. She could just barely hear soft grunting as she approached the door. Curious, she pushed it open a crack and peeked inside...

Her jaw dropped.

* * * * *

"And now Sunset's been gone a long time," Twilight said. "What's going on around here?"

"Ooooh, maybe it's a serial killer!" Pinkie said in a spooky voice, waggling her fingers.

"PINKIE!" Rarity cried.

The door flew open. Sunset rushed in, nearly falling down. She was breathing heavily. "Oh my gosh, oh my gosh, oh my gosh," she said.

"Sunset? What is it?" Twilight asked.

Sunset shook her head and scrabbled around on Applejack's desk, snatching up her phone. "You girls have GOT to see this," she said. "Wait here, I'll...I'll...just..." She shook her head. "Grab your phone, Pinkie. Wait for my text." She rushed back out the door.

The girls looked at each other in confusion. Rainbow grabbed Pinkie's phone off the desk and tossed it to her.

~Fifteen minutes earlier~

Fluttershy quietly opened the door to the master bedroom and snuck inside. She was a girl on a mission. A girl with a burning, secret desire.

A girl who was scared out of her mind, yet filled with a heady rush of excitement.

Fluttershy was about to do something naughty.

Big Macintosh lay sprawled on the large bed, a paperback novel lying open and forgotten near his head. The lamp over the bed was still on, suggesting Big Mac had fallen asleep reading. As warm as the evening was, he was wearing boxer shorts and nothing else. He was snoring gently as his bare chest rose and fell.

Fluttershy padded slowly over to the bed, studying the sleeping farmer. Her heart hammered in her chest. She'd always had a slight crush on Big Mac, although she'd never acted on it. He was so gentle, kind, soft-spoken, and strong...and very handsome, at least in her opinion.

But tonight, none of that mattered. Tonight, Fluttershy was interested in only one thing.

His dick.

All week long, Fluttershy had been having naughty thoughts. At the most inopportune times, her mind would go straight down the toilet, and she'd find herself heating up. When the decision had been made to hold the sleepover at Applejack's house, she knew what she had to do.

Fluttershy knelt at the side of the bed and gently fumbled open the front of Big Mac's boxers. Red-faced and trembling, she reached in and brushed his manhood with her fingers. Gulping nervously, she brought it out, holding it in her hand and looking at it. "Oh my," she whispered. Hesitantly, she began gently stroking it, thrilling at the alien feel of it beneath her fingers. She nearly squeaked in fright as it began to stiffen under her touch; Big Mac stirred slightly, and Fluttershy ducked under the bed, muffling her breathing.

After a long, heart-pounding minute, she crept back out and stood up.

Big Macintosh was still asleep...and his dick was standing proud outside of his shorts.

Gulping nervously, Fluttershy leaned down over the bed and prodded Big Mac's manhood with a fingertip. Stifling a giggle, she crouched low and wrapped her hand around it, stroking its length, feeling the hot blood pounding inside. With a silly smile, she leaned forward, tongue lolling out...

"Fluttershy? Whut're you doin'?"

"EEP!" Fluttershy yelped, jumping away, eyes wide. She stared at Big Macintosh as he sat up, blinking dozily at her. "Umm...umm...I...oh goodness..."

Big Mac looked down at himself, blushed furiously, and tried to scramble under the covers—which he had never bothered to pull back. He tried to tuck his twitching member back into his shorts, but failed.

"Umm...I...I'm sorry," Fluttershy whimpered, ducking her face behind her hair. "I..." She swallowed. "I shouldn't have..."

"Why were you..." Big Mac's face turned even more red. "Why..."

"Please don't be mad at me," Fluttershy said. "I just—"

"Ah ain't mad," Big Mac said. "Jes' confused." He tried to cover himself again; his manhood was beginning to flag at last.

"Oh. Good. Well..." Fluttershy took a deep breath. "I'll just...I'll just be going back to the girls now..."

"Wait," Big Macintosh said, shifting around. "Ah wanna know why first."

"Oh..." Fluttershy gulped. "W-well..." She blushed and played with her hair. "I...I've just...been..." She stammered. "I-it's been a...a strange week...I can't seem to stop thinking a-about..." She ducked her head. "Sex," she whispered. "A-and, well...I always...sort of had a crush on you...a little bit..." She picked at the hem of her shirt. "I...I just wanted to...play with...a little..."

Big Mac stared at her, eyebrows raised.

"I-I know it was wrong," Fluttershy said. "I...I'm sorry..."

Big Mac shrugged. "There's worse things t'wake up to," he said. He looked her up and down and ducked his head. "Matter of fact, that's probably th' best thing Ah ever woke up to."

"R-really?"

"Eeyup."

Fluttershy smiled shyly, playing with a strand of her long pink hair. "W-would...would it be okay if I...did some more?"

Big Mac smiled lazily at her. "Eeyup."

Giggling, Fluttershy stripped off her T-shirt...

* * * * *

Pinkie's phone played an obscenely cheesy song about space unicorns. She tapped the screen a couple of times. The girls crowded around her as a video appeared on the screen.

Rarity gasped. "Good heavens!"

"Whoa," Rainbow said, jaw hanging open.

In the video on the little screen, a nude Fluttershy knelt atop a prone Big Macintosh, whose hands rested on her hips. She ground and thrust her hips repeatedly against him, arching her back and moaning in ecstasy. Her breasts bounced with each thrust.

Twilight stared, face red. "Is she..." She swallowed audibly. "Are—are they doing what I think they're...?"

"Wowie, look at her go!" Pinkie said, awe in her voice.

"I...I never would have expected something like this from Fluttershy," Rarity said, cheeks flushed.

"Same here," Rainbow said, watching wide-eyed. "Holy crap."

Twilight shook her head. "We shouldn't be watching this!" she said.

"Ah agree with Twi," Applejack said. She grabbed the phone away from Pinkie. "That jes' ain't right."

Rainbow snatched the phone back from her and leapt away; the rest of the girls minus Applejack crowded around her.

"HEY!" Applejack yelled. "That's MAH BROTHER in there! This ain't right!"

"Quiet, we're watching this!" Pinkie said.

"Yeah, AJ! Just...chill out or something!"

"Good grief, y'all..."

Despite herself, Twilight watched the video curiously. "So...in this world, the females mount the males?"

"Sometimes," Rainbow said. "There's a lot of different ways you can do it."

"I always pictured Fluttershy as the kind who'd be on the bottom," Pinkie said. "Not...not THIS!"

"I didn't even know they were seeing one another!" Rarity said.

"They ain't, far as Ah know," Applejack said, still refusing to look.

"Yeah, Fluttershy woulda told us if she had a boyfriend," Rainbow said.

"Then why is she...?" Twilight asked. "Is...is she in estrus or something...?"

"People don't got estrus," Applejack said.

"Yeah, we just get horny," Pinkie agreed. "And Fluttershy sure looks horny!"

Fluttershy threw back her head and let out a ragged moan they could hear from down the hall. On the screen, she jerked once, twice, three times...then sagged forward, falling against Big Macintosh. He wrapped his arms around her gently, and she kissed him, lacing her hands around the back of his head.

The video ended.

"Aww," Pinkie said.

About half a minute later, Sunset Shimmer walked back in. "Did you girls watch?"

"Sunset Shimmer, how COULD you?" Applejack roared. "Dammit, girl, spyin' on mah brother an' your best friend...that jes' ain't right!"

"Yeah, Sunset, that was pretty messed up!" Rainbow said. Then, with a sly grin, she added, "Thanks for lettin' us in on the show, though!"

Sunset shrugged. "Hey, when you stumble across something that completely unexpected..."

Twilight shook her head. "It isn't right to invade a friend's privacy like that, Sunset."

Sunset sighed. "Yeah, yeah...I know..." With a smirk, she added, "But I bet it gave you some ideas for the next time you see Flash Sentry, right?"

"Eep!"

The other girls laughed. "Okay, come on now," Rainbow said. "Let's get back to the game. Sunset, it's your bet..."

* * * * *

"That was th' most amazin' thing Ah ever done," Big Macintosh said softly, stroking Fluttershy's cheek. Cupping her bare breast in his hand and kneading it gently, he whispered, "Ah wouldn't mind...another go..."

"Yay..."

Big Macintosh turned off the reading lamp, and the bed springs started to squeak...
