1 - Twilight’s Friends are HOT

Twilight Sparkle sat with her friends in a circle, in her pajamas like her friends, enjoying her Friday night chatting and gossiping at her very first slumber party. It was something she hadn't considered before with all her experimenting outside of school, on top of the usual workload high school dumped on students. Pinkie Pie was becoming particularly impatient when she mentioned she was hosting a slumber party and began just leaving notes for Twilight around the school, and getting to the point of just following her around and constantly asking, "Are you coming? Are you coming? Are you coming?" until Twilight eventually caved. Annoyed as she was, Twilight warmed up to the idea the more she thought about it. It might be fun to hang out with her friends for a night and get to know them better. Plus, Twilight needed a break, especially after Monday.

Twilight sat holding her knees close and leaning against the Pinkie's bed frame.

It's okay, Twilight. Just stay calm and you'll be fine. Try to enjoy yourself.

Twilight's thoughts seldom helped. Her friends were sharp and knew her well. It was only a matter of time before the realized something was up. When her friends weren't looking, Twilight quickly adjusted herself between her legs. Something she never thought she would have to do until last Monday when all hell broke loose when a volatile experiment went wrong. This experience was like something out of a hentai. Something so unbelievable that it could only exist in hentai. Somehow Twilight made it happen in real life. To her credit, it must mean she's some kind of genius, but the sentiment didn't help her predicament. She had never even seen one before she accidentally endowed herself with her own, so she had little knowledge of how they worked. At least it didn't rob her of her normal parts down there. If she could only figure out a way to get rid of the stupid thing.

"Did you hear about Trixie?" Rarity said, breaking Twilight's train of thought. Maybe getting in on the gossip would help distract her from her situation.

"What did 'The Great & Powerful Trixie' do this time?" Rainbow asked, rolling her eyes.

"I saw Brawly Beats rehearsing with her band on Thursday," Applejack said, "Somethin' to do with that?"

"Yes!" Rarity exclaimed. "I caught her talking to him in the corner of the hall. She was really coming onto him."

"Seriously? What'd you hear?" Sunset asked.

"She told him if he needs more encouragement to join her band, she can suck him off again," Rarity said.

All the girls gasped.

"Trixie gave brawly a blowjob???" Pinkie shouted.

"Oh my…" Fluttershy said, "I didn't think Trixie would do something like that."

"I dunno," Rainbow said. "She's persistent. When she wants something, she goes for it."

"I've seen the way she looks at Brawly too," Sunset said, twirling her hair. "Can't say I blame her, though."

"He is quite a hunk," Rarity said, blushing slightly.

"I'll say," Applejack said. "Y'all seen those muscles?"

Pinkie giggled, "I gave him a random hug one day just to feel those biceps… mmm…"

"I heard him drum once," Rainbow said, "and he started sweating during his solo…"

Twilight couldn't help but blush. She knew who they were talking about, and she had to agree. Brawly Beats was rather hot. Her heart dropped when she felt something twitching between her legs. Oh no…

"How big do you think he is?" Sunset asked.

"I'd imagine rather large," Rarity said, blushing even more now. "Trixie was looking at him like she enjoyed what she did the last time. She had a certain look in her eye."

"Wait!" Pinkie said. "Is Brawly single?"

"I don't know," Applejack said, "I'd imagine some gal has already taken someone like him, though."

"Maybe now it's Trixie," Rainbow said with a chuckle.

"That's no problem. I'm totally hotter than Trixie!" Pinkie said, standing up and leaning on her hips, posing like a model.

"Most girls at the school are hotter than Trixie," Rainbow said. "I mean, Trixie has a nice body and all, and she's got a great chest, but the way she acts would turn any guy off."

Twilight felt it again. A twitch between her legs. Was it Pinkie's modeling? Rainbow talking about Trixie's body? Both? Why is it doing this now? At least her pajama pants had some room to breathe so it wouldn't just start poking out and making a scene.

Just ignore it, Twi. Ignore it and keep your legs close to your body.

"I'm hotter than a lot of girls at school!" Pinkie protested. To everyone's surprise, she took her shirt off, revealing a pink bra with white lace, and plenty of cleavage. "Not every girl at school has D cups!"

"Pinkie!" Rarity said. "Have some decency!"

"C'mon, Rarity!" Pinkie said with a big smile. "We're all friends here! It's not like anyone else is gonna see. Don't you think these boobs could make a guy like Brawly hard?" She started fondling herself with the biggest grin. "And what about my butt?" She turned around a pulled her pants down, revealing a matching pair of cheeky underwear. "My booty could totally kick Trixie's flat butt!" she said, giving it a good shake.

Applejack chuckled. "Trixie does have a big ol' rack, but she has the flattest butt I’ve ever seen.”

“Are you sure she even has one?” Rainbow remarked.

All the girls giggled, seemingly unbothered that Pinkie was in her underwear showing off her body to her friends. Pinkie leaned on her hips again and put her hands behind her head.

"My body could totally out-hot Trixie's. I could steal Brawly from her any time I wanted!"

Twilight couldn’t help but stare at Pinkie. She never noticed it before but… Pinkie had every reason to brag about her body. She was super hot. Her underwear did little to hide her features, accentuating them, even. Her boobs like two large, perky yet bouncy melons, a big jiggly butt, those thick thighs, all complete with such sexy curves and a heart-melting smile…

Twilight blinked. What was she thinking? Looking at her friend like she's a piece of meat? She's even seen her in a swimsuit before, and she didn't get this mesmerized by her body like now. But that was before her… predicament. Since the mishap, Twilight has found herself looking at her friends differently. In a more sexual way. Was it changing how she thinks that significantly?

Pinkie's your best friend! Why are you looking at her… curvy… sexy…

Twilight had to snap herself out of it. She was getting too excited. If she got too excited, she'd get too big and hard down there, and really have something to worry about.

"For goodness sake's darling," Rarity exclaimed, "I agree you have a gorgeous body but… can we have some decency?"

"Oh c’mon, Rarity. I’m just proud of my body. I could make any guy melt with a little butt shake! Besides, I know a thing or two about how to suck a cock," Pinkie said with a sly grin.

"Oh please!" Rainbow said, standing up and taking her shirt off, revealing a rather brilliant rainbow bra.

"Oh Rainbow," Fluttershy squeaked, her face bright red at what was happening, "Not you too."

"Well, my tits might not be as big as Pinkie's. I've only got B cups. But…" Rainbow turned around, presenting her backside to everyone and pulling her pants down, showing a matching pair of rainbow underwear. She got on her knees, sticking her butt out for all to see. "…what I do have, thanks to me being the most athletic girl in school, is a nice firm ass."

Twilight's mouth was practically watering. She was now about half-mast, and still growing. She almost didn't care. Rainbow's backside looked so good. It wasn't as big as Pinkie's, but it looked firm and taut. She never thought she would see Rainbow showing off her body like this. A rare sight.

"If there's anything guys go nuts for, it's a firm booty like mine," Rainbow said, shaking her rear a little.

"Y'all ain't the only one with a tight behind," Applejack said, following suit with Rainbow and Pinkie. Her underwear was a bright green color, matching her eyes. "I don't have boobs like Pinkie's, but mine are C's. Still bigger than Rainbow's." She posed for a second, wanting the girls to get a good view.

Twilight was about three-quarter mast by this point. Applejack's body was toned. A muscular body from all the farmhand work, but still with a feminine hourglass figure like Rainbow and Pinkie. Twilight felt warmer, almost like she was going to start sweating. One third of her was turned on by seeing three of her beautiful friends almost naked and showing off their bodies, another third was ashamed for being turned on by her friends, and the last third was terrified of her friends seeing her slowly growing member. Twilight held her legs to her torso as if letting go would instantly kill her (as far as being embarrassed and ashamed goes, it probably would).

"Besides, y'all don't need a good rack when ya got an ass like mine!" Applejack said, bending down adjacent to Rainbow, positioning both their firm, toned booties next to each other.

Pinkie growled. "Oh yeah? Well can your butt bounce like mine?!" she said, shoving herself right between Applejack and Rainbow, forming a row of their booties, before Pinkie started to twerk for everyone in the room. Rarity and Fluttershy just stared in shock, being the two most opposed to what was happening.

"Wooo! Work it, Pinkie!" Sunset cheered.

"Oh yeah? You're not the only one who can twerk!" Rainbow said, starting to shake her butt as well.

"Hmph. I can go faster than all y'all," Applejack said, shaking her rear at a faster pace than either Rainbow or Pinkie.

Twilight stared in shock… and awe. Pinkie's butt bounced and jiggled like jello, easily the biggest of the three. Rainbow's taut rear bounced a little too, but it was still sexy to watch her move like that. Applejack just kept going and going, her muscles enabling her to bounce at a greater rate. Twilight couldn't stop her member from increasing in size to ninety-percent mast. Full mast was imminent at this point, but Twilight couldn't find it in herself to care. Her friends looked so sexy bouncing their asses, and all of them wearing cheeky bottoms that didn't cover their rears much whatsoever. All she wanted was to go up to all three of them and just… just…

Twilight! Stop! They're your friends! Don't think about them like that! Besides, it's just… girls being girls? Is this how all their slumber parties go? Oh my gosh, they're so hot…

"I could drive all the boys on the field crazy by doing this," Rainbow said, giving her rump a good smack, continuing to twerk. "Especially if I were in leggings or my spandex."

"I'd give all them boys pitched tents if I wore my shorts," Applejack said. "I've got some that just show the bottom of my cheeks."

"Can you imagine if they were watching us right now?" Pinkie said. "They'd probably have to rush to the bathroom right away to rub one out!"

"You girls are sexy," Sunset said. "I know I'd need to get off after seeing this."

Rarity and Fluttershy just blushed. Fluttershy bit her lip pulled her knees closer to her, watching her three friends shake their butts. Her face was a deep crimson red. Rarity, surprisingly, was twirling her hair and biting her finger.

"I think it's… gotten warmer in here," Rarity said, blushing hard.

"Of course, it is!" Rainbow said, still twerking. "We're hot!"

"See, Rarity?" Applejack said. "There ain't no harm in this!"

"I've got all of you beat," Sunset said behind the three twerking girls. "Why don't you turn around? Ever seen a girl give a striptease?"

The three girls immediately stopped and turned around, sitting beside each other to watch Sunset.

"Oh boy! A striptease!" Pinkie said, bouncing in excitement, her big boobs jiggling with her.

"Have you given one before?" Rainbow asked, raising an eyebrow.

"I've seen enough videos to know what happens," Sunset said, putting her hands on her hips. Her tone changed to one that was more lilted and seductive. "But I'm giving you girls my very first one." She lifted her shirt up, showing off her smooth, yellow skin.

"Hoo-wee!" Applejack exclaimed. "I reckon it's gettin' hot in here!"

"It's about to get even hotter," Sunset said, leaning on her hips and giving her friends a beguiling look. "Enjoy, girls."

Twilight bit her lip. The thought of Sunset stripping was enough to make her harder on its own, but to see her begin to dance… it was becoming too much.

Sunset swayed her hips side to side, running her hands up and down her curvy, hourglass figure. When her hands reached her boobs, she fondled them briefly and bit her lip before moving back down. She moaned at each intimate area her hands reached. Her hands arrived at her thick thighs before coming back up to her hips. She played with the waistband of her pajama pants, rotating her hips as she turned around. Looking back at her audience, she smirked when she saw them staring in awe. She spread her legs and bent over, giving her cheeks a good shake before slowly starting to pull her pants down just past her butt's curvature. Her underwear was red, orange, and yellow in a pattern of diagonal lines, and was also cheeky like Pinkie, Rainbow, and Applejack's, showing everything her booty had to offer. She let her pants fall, exposing her thick, meaty thighs. She kicked her pants aside and spread her legs, shaking her butt for everyone. She gave herself a spank, sending luscious ripples across her cheeks and legs, and then slowly and seductively bent over and began moving her ass up and down, as if she was twerking in slow motion.

"Oh my," Rarity said under her breath.

"Damn, Sunset!" Rainbow said. "That butt, though!"

"Y-You sure seem to… um… know what you're doing," Fluttershy said quietly, almost inaudible.

"Y'all got some moves," Applejack said. "Can you go any faster?"

Sunset giggled. "Of course, I can," she said before bending her knees further and began to twerk herself. Her round, yellow cheeks bounced at their own tempo, showing off just how thick her booty really was.

"Yeah, Sunset!" Pinkie cheered. "Work it, girl!"

Twilight couldn't stop the inevitable. She was full mast. It was as hard as it could get. Watching Sunset show off her butt like this was too much. Her mouth was watering severely. She thought she might start sweating with how warm she felt, thanks to a combination of being turned on by Sunset and stressing about losing control of her… problem.

She straightened her legs, standing up while still sticking her butt out. She gripped the bottom of her shirt and pulled it over her head, revealing her back, along with bra straps of an identical color scheme to her bottoms.

"Want to see my girls?" Sunset asked, leaning on her hips and bringing her hands up to her chest. "Or do you want to keep looking at my ass?" she said, giving herself a good swat.

"Let's see those knockers!" Applejack said.

"Show us your boobs!" Pinkie said.

"Yeah, Sunset!" Rainbow cheered. "Turn around!"

Sunset giggled, and with one more shake of her thick booty, turned to face her audience, leaning forward to give them a good look at her chest. Her push-up bra did little to hide her huge assets. It looked like she could pop out at any second. She brought her hands up to fondle herself with a big seductive grin.

"You like them?" Sunset said.

"They're so big!" Pinkie said.

"Mmmhmm!" Sunset said, moaning as she fondled them more. "DD's. I wear a tight top, and I have every guy’s attention.”

Sunset stood up straight, her hands still cupping her big breasts. She brought her legs together and started gyrating, rotating her hips and accentuating her midriff. She smiled as she slowly bent her legs, and then straightened them again, all while she fondled her boobs.

"Sunset, darling," Rarity said. "You're gorgeous. Your body is captivating."

Sunset giggled, continuing her sensual dance. "Thank you, Rarity. I'm glad you've warmed up to all of this. What do you think, Fluttershy?"

Fluttershy blushed but gave Sunset a smile. "Y-You're beautiful, Sunset."

Sunset smiled. "Twilight? What about you? Do you like what you see?"

Twilight had never felt hotter in her life. It felt like a fire ignited in her heart. All she could muster was a quiet, "Mmmhmm!"

Sunset gave her a smirk, and a wink before continuing her show.

"I could get any guy I wanted by doing this," Sunset said, her audience nodding in agreement.

Twilight bit her lip so hard she was afraid it was gonna bite it clean off. Sunset looked sooooooo hot. The way she looked at her melted her heart. She was already full mast, feeling like there was a stone between her legs, but Sunset was so sexy she could feel it pulsating, as if it wanted to get bigger. It was starting to hurt a little, but Twilight's could do nothing about it. She could feel the lust simmering inside of her. She needed some form of relief, but she couldn't just get up and walk to the bathroom. Everyone would see the big bump jutting out from between her legs!

With no other options, and with a hint of shame, Twilight reached her hand into her pants, her legs still bunched up against her chest as to hide her raging erections. She began softly petting it, but even softly touching it sent shivers through her body. She had to bite her lip even harder to stop herself from moaning. It felt so good, especially when she watched Sunset. Watching Sunset seemed to immediately amplify the feeling. Twilight continued softly brushing herself with her fingers, savoring each ripple of pleasure. She knew she wouldn't be able to finish without ruining her clothes, but perhaps just a little attention would calm it down.

"And now, for a little finale," Sunset said. Twilight wondered what she was up to, but almost immediately came at what she saw her do next. Sunset sat down on her knees, and began gyrating again, slowly moving her torso up and down to make it look like she was riding something… or someone. At the same time, she fondled her boobs and ass, and tossed her hair. She moaned as she danced. It seemed like she was getting horny.

"Yeah! Get it, Sunset!" Pinkie cheered.

"Y'all can ride almost as well as me!" Applejack said with a giggle.

"I think I would've exploded all over you right now if I were a guy," Rainbow said.

Sunset giggled, and noticeably blushed. Twilight had to stop. Hearing Rainbow say that almost sent her over the edge, especially since she was getting exponentially closer and closer to finishing anyways. She could only agree with Rainbow. For some reason, she wanted to finish all over Sunset right now. Twilight had an urge to explode all over Sunset's face and just ruin her.

"Well… that's about all I got," Sunset said, sitting opposite of her audience. The girls all gave her a big round of applause, making her blush.

"Sunset, that was soooooo hot!" Rainbow cheered.

"You were like a supermodel!" Pinkie said.

"Well, I wouldn't say that," Sunset said. "Besides, I might've gotten a little too into it…"

"Sure made for a sexy show, sugarcube," Applejack said. "Y'all can sure move that body."

"Were you getting horny up there?" Rainbow asked, raising an eyebrow.

Sunset blushed. "Um… well…"

"Ooooh! Dirty girl!" Pinkie said.

"Oh hush, Pinkie," Rarity said. "It was captivating, darling."

Sunset was blushing hard. "Thanks, girls. But enough about me. I still see three girls in this room with clothes on."

Fluttershy squeaked, holding her legs closer. Twilight immediately stopped teasing herself, taking her hand out of her pants and trying her best to be nonchalant.

"C'mon, girls!" Pinkie said, "Let's see what everyone's got!"

"Yeah!" Rainbow agreed. "Let's see what the three other hottest girls in school have!"

Fluttershy blushed profusely. "Um… I'm not sure I…"

"C'mon, Fluttershy!" Rainbow said. "You, Rarity, and Sunset have the biggest tits in our group! Let's see them!"

Fluttershy blushed, knowing the white tank top she was wearing did little to hide her assets. She swiftly covered her chest. "Rainbow! That's dirty!"

"Don't be scared, Fluttershy!" Pinkie said. "You really are one of the hottest girls in school! Besides, nobody else is here!"

Fluttershy's face just got redder. "Oh, don't be silly. I'm not hot."

"Sugarcube, I catch so many guys checking us out in school," Applejack said. "There's no doubt. Can y'all imagine if a guy was actually here right now?"

"He'd be as hard as diamond! Not like he'd get any of this though," Rainbow said, giving her butt a quick spank. "C'mon, Fluttershy! Let's see what you got!"

Fluttershy just blushed harder. "I still don't know."

"Darling?" Rarity said. "Will you do it if I do it?"

Fluttershy's eyes widened. "Rarity, you don't have to…"

"Nonsense," Rarity said, blushing slightly. "It is getting rather hot in here," Rarity said. She turned her back the girls and flashed a beguiling glance at them, slowly lifting her nightgown to reveal her thick, white rump. "I work hard to maintain my body, and if my beautiful friends are curious… it wouldn't be very generous to keep them wondering would it? Just sit back and relax, my darlings."

Rarity kept her nightgown lifted and began bouncing her hips side to side, starting off her own show with a bang. Her underwear was a deep indigo color, matching her hair, studded with sapphires around the waistband. She started moving her butt up and down, similarly to Sunset, as if it was twerking in slow motion. Rarity continued the theme of cheeky underwear, with her plump butt cheeks fully on display. For a short burst, she twerked faster, showing how bouncy and jiggly she really was. Her cheeks sent ripples down her elegant, juicy thighs and seemed to bounce with its own tempo like Pinkie's. She gave herself a quick spank, making her squeak, before gyrating again.

"What a man really wants is for a lady to seduce him," Rarity said, swapping between gyrating and slowly twerking, occasionally stopping to shake her backside. "Do you like what you see?"

"Hot damn!" Rainbow said. "You're thick back there, Rares!"

"I love how it jiggles!" Pinkie said.

"I think Rarity and Sunset could get any guy they wanted with bodies like that," Applejack said.

"Rarity, you have the body of a supermodel!" Sunset said.

Twilight bit her lip once more. Her erection had subsided slightly after Sunset's show, but Rarity was doing the same thing to her all over again. Perhaps it was even greater because of how conservative Rarity usually is with her wardrobe and wouldn't be caught dead doing anything like this in any other setting. It was a rare sight. Watching Rarity's thick cheeks bounce as she moved her hips brought Twilight to the brink of her desires again. She slipped her hand back into her pants and carefully massaged her rock-hard erection again. The shivers were just as exhilarating as they were with Sunset, but she still had to muffle her moans.

Rarity blushed but maintained her seductive gaze. "Thank you so much, girls. You're all so kind. But you haven't seen anything yet."

Rarity gave her backside one more swat before turning around with a grin. She took off her nightgown, and everyone in the room was floored by how perfect her body was. Her white skin was flawlessly smooth, looking like silk. Her bra matched her underwear, with deep indigo satin cloth studded with sapphires on the straps and underwire, bringing out the color of her flowing hair and starlight eyes respectively. Her figure was a perfect hourglass, with wide hips and elegant, juicy thighs. She posed like a model at the end of a runway, further accentuating her features.

Twilight scanned her body, which twinkled with perfection, and then brought her attention back up to Rarity's chest. Her push-up bra accentuated her cleavage, and it looked like her breasts could pop out at any moment. They were as big as Sunset's and looked as smooth as silk, just like the rest of her body. Twilight could feel herself getting closer just from looking at Rarity's supermodel body, so she had to slow down her stroking. However, she found she couldn't stop. Rarity was just too sexy to stop. She felt a desire to fondle Rarity's boobs and just caress her body. It looked like she would be so amazing to touch.

"Rarity… you're so beautiful," Fluttershy said, gazing in awe.

Rarity smiled. "Why, thank you, Fluttershy!" Rarity studied her friends and pinpointed where they all were looking, and she could only oblige them by bringing her hands up to fondle her gigantic boobs. "Aren't they beautiful?" They all nodded, making her giggle. "Mine are also DD's. It's hard to make clothes for them sometimes, but they attract so much attention!"

"I think Rarity would make every guy faint if they saw her like this," Sunset said.

"You're so pretty!" Pinkie said.

"That's the most perfect body I've ever seen!" Applejack said.

"What else are you gonna do for us, Rarity?" Rainbow asked, eager to see what else the fashionista could do with her body.

Rarity didn’t say anything, instead giving a beguiling smile before bending her knees and gyrating again. Her hands moved between her wide hips and big boobs, making her moan at each destination. Her boobs bounced with each rotation of her hips, showing off how big and round they are. Rarity seemed to be getting a little horny as well, just like Sunset was.

Twilight felt the same desire she had for Sunset when she fondled herself and moved her hips. She wanted to finish again. She was on the brink. She had to stop, but Rarity was just too hot to stop altogether. She could only slow down, but even that felt dangerous with Rarity looking as delicious as she did. Each horny moan Rarity uttered seemed to bring Twilight closer all on its own, seemingly to the very edge.

"That is so hot!" Rainbow said. "We had no idea you could move like that, Rares!"

"I reckon I would've blown a few loads for her by now," Applejack said, making the girls giggle.

Rarity tossed her hair and flashed a smile at her audience. "That was so exciting! But I think that's enough for now."

Everyone applauded her, and Rarity curtsied before taking a seat.

What a relief. Twilight almost couldn't take it anymore. She could take a rest. She felt her erection subside, but only slightly. The sight of all her hot friends half-naked was still enticing. She's certain she would've exploded a few times as well for Rarity. The entire time she was working her erection, the only thought she had was finishing all over her friend. The thought of soiling such a perfect girl was turning Twilight on. But… why? Was this just a guy thing that Twilight was now experiencing thanks to her new member? She also couldn't help but feel ashamed that she basically just masturbated to two of her best friends, and thought dirty, kinky things while doing so. These were her friends! How could she possibly think about such things? And yet, looking around at all her half-naked friends…

"I hope you enjoyed that," Rarity said.

"That was amazing, Rarity," Sunset said. "Your body is perfect."

"I didn't know a body could be that flawless," Applejack said.

"Why, thank you girls," Rarity said, blushing slightly. "It was fun. I'm sorry for protesting earlier."

"It's okay!" Pinkie said. "We're just friends having fun."

"You were great, Rarity," Rainbow said. "Now who's next?"

Rarity looked at Fluttershy, making her gasp.

"Fluttershy, sweetheart?" Rarity said. "Do you think you'd be more comfortable now?"

Fluttershy shook her head. "How could I possibly follow you? Your body was amazing, and so was your dancing. I-I’m not as pretty as you. I don't even know how to dance, especially not like you and Sunset."

"I just thought the dancing would add some flair," Sunset said. "I didn't mean to upstage anyone.”

"Nor did I," Rarity said. "We won't judge you, darling. You're a beautiful girl. One of the prettiest in the entire school."

Fluttershy blushed. "I… I am?"

"Sugarcube, y'all would be surprised how many times I catch guys sneaking glances at you," Applejack said. "All of us, really."

Fluttershy twirled her hair. "Guys sneak glances at me?"

"C'mon, Fluttershy!" Rainbow cheered. "You're hot!"

"You're sexy!" Pinkie cheered.

Fluttershy whimpered. She looked at all her friends and sighed. There really wasn't a way out of this.

"O-Okay," Fluttershy said. "I'll do it."

The girls cheered, making Fluttershy blush profusely.

On the inside, Twilight was cheering too. The other girl with the more conservative wardrobe was about to show herself off as well. Twilight could feel herself getting hard again already, but at this point she was starting to not care anymore. It was the hormones from her new endowment, and she knew that, but could not resist being turned on by her friends anymore. She would feel ashamed later, but for now she just wanted to ogle her sexy friends.

Fluttershy trembled as she took off her shirt. Even with her friends smiling at her and knowing they were the only ones here, she was finding it hard to get her shirt off. She always assumed the first time she stripped down to her underwear would be for her first boyfriend or something.

"Need some help, darling?" Rarity asked, seeing that Fluttershy was struggling.

Fluttershy nodded, knowing she would be too nervous to do it herself. She looked at Rarity's impeccable body as she felt her friend's hands grip her shirt. How could she even dream of comparing with Rarity's supermodel body, or any of her friends?

Rarity lifted the shirt over her head, and Fluttershy instinctively held her hands over her cleavage. After some deep breaths, she brushed her hair behind her and put her hands behind her back, allowing her to be exposed to her friends in just a bra.

Twilight just stared again, immediately starting to rub her erection again. She felt no shame in doing so, at least not now. Her hormones were going crazy. The teasing was actually making her problem worse in the long run, due to an increasing craving for release and feeling of being bloated between her legs to the point where it began to hurt. Even so, Twilight continued rubbing herself off gently to her shy friend.

Fluttershy had the most petite body of her friends, but that didn't make her any less sexy. Her underwear was a solid deep teal color, matching her eyes. She wore a push-up bra, showing plenty of delicious cleavage. Her cream-colored skin looked so smooth, and her figure was a gorgeous hourglass shape, just like the rest of her friends.

"Oooh, Fluttershy!" Pinkie said. "Seeexy!"

"Hot damn!" Rainbow said.

"Y'all had nothing to worry about, sugarcube," Applejack said. "I love what I see so far!"

"Such a gorgeous figure, darling," Rarity said. "And your garments bring out those beautiful eyes of yours."

"And that cleavage!" Sunset said. "You're gorgeous, Fluttershy!"

Fluttershy's face went bright red. "M-My cleavage? Oh, it's not that impressive. My boobs aren't as big as yours or Rarity's. Th-They're only D's."

"So what?" Sunset said. "They're still big. They’re as big as Pinkie’s. And so round and perky. Guys like perky breasts."

"R-Really?" Fluttershy said. "Am I really that pretty?"

"Sweetheart, you're beautiful!" Rarity said. "Why don't we see the rest of you now?"

Fluttershy blushed and nodded. With her friends complimenting her body, she didn't seem to hesitate too much saying yes to having the rest of her clothes removed. Rarity helped her again, and when her pants hit the floor, everyone looked at her in awe, which immediately made her blush. She did her best to keep her hands behind her back so her friends could get a good look at her.

Twilight couldn't believe how hot Fluttershy looked. She always thought she was pretty, as she thought with all her friends, but one could've only guessed how fine Fluttershy really was. Twilight had to slow her stroking down again so she didn't finish and ruin her pajamas, the only barrier hiding her member from the outside world. But as with Rarity and Sunset, she found she could only slow down her stroking, and never truly stop. She couldn't stop. Fluttershy's sexiness wouldn't let her. It felt too good…

"Damnnnnn," Sunset said. "Fluttershy is fine."

"Darling, why are you so insecure about your body?" Rarity asked. "You're have such a dazzling figure."

"Look at those legs too!" Rainbow said. "Those thighs are thick!"

"Th-Thick?" Fluttershy said. "Are my thighs too fat?"

"No, no, no! Thick thighs are good, Fluttershy!" Rainbow said. "Guys love legs like yours."

"Your figure is amazing," Applejack said. "Nice and curvy, but so petite and cute, just like yourself!"

"Now show us your butt!" Pinkie said. "Let's see what you got!"

Fluttershy bit her lip, but maybe if she had the wrong idea about her body so far, perhaps her butt would follow suit. Taking a deep breath, she turned around. Everyone immediately went, "Oooooh!", making her face flush red.

Twilight was practically drooling as she continued to rub herself off, brushing her erection with her hand. She had to stop. She was getting too close. It was just like with Rarity. Her moans were getting harder to hold back as the desire to finish increased seemingly infinitely with every stroke. But she couldn't stop. Fluttershy was too hot to stop.

"Look at that thick booty!" Rainbow said. "And yes, Fluttershy. A thick butt is also a very good thing."

"She could get any guy she wanted too," Applejack said.

"I think we all could," Sunset said. "Bend over a bit, Fluttershy. Show that rump off for us."

Fluttershy bit her lip as she did, holding her breath for any criticism they might have of her body, but she got none whatsoever. Just a non-stop stream of compliments.

"Hot damn!" Sunset said. "Fluttershy, your body is amazing!"

"So sexy!" Pinkie cheered.

"How is it that no boy has asked you out yet?" Rarity asked. "You're so adorable and sexy, darling!"

Fluttershy blushed, relishing the compliments about her body. She always looked at girls in her school and wished she was as beautiful as they were, but maybe she already was. She recalled some of Sunset and Rarity's moves and tried moving her hips side to side to shake her butt.

"Ooh, Fluttershy!" Pinkie cheered. "Work it, girl!"

"That's so hot!" Rainbow said.

Fluttershy blushed more. She was a hot girl! She could finally think that with some confidence. Since she was enjoying the attention more than she thought she would, she turned around and fondled her boobs.

"I-Is this sexy?" Fluttershy asked.

"Oh, darling. It's divine," Rarity said.

Fluttershy giggled, giving her friends a big smile. "Okay… um… I think I'm done now. Th-Thank you so much."

The girls all gave a big round of applause.

Rarity gave her a big hug. "You are just the cutest thing in the world!"

"Way to be brave, Shy!" Applejack said.

"Mmm!"

The girls all stopped when they heard a stifled moan coming from who had been the quietest person at the party so far, and the only one with clothes on. They turned around and saw Twilight with her hands in her pants and with bug eyes. Her hair was slightly messy as if she had been sweating, and her face was bright red. She immediately took her hand out of her pants and held her legs close to her torso.

"You alright, Twi?" Applejack asked.

Twilight froze. Now it was her turn to show her body off. There was no getting out of it at this point. Not only that, but they heard the moan that managed to escape. Why didn't she just stop? She knew she was getting too into it! She held her legs in a death grip against her torso, desperately hoping they would arbitrarily decide she doesn't have to undress. Although her legs had been in this position for so long, they were beginning to get sore.

"Um… y-yeah, of course!" Twilight said. "Why wouldn’t I be?"

"Were you… masturbating?" Rainbow asked.

Twilight bit her lip. She only stammered.

"Uh… uh… um… well…"

"She was!" Pinkie said.

Twilight's heart dropped. She had been caught. What were they gonna think of her now?

"That's… actually kind of hot," Sunset said.

Twilight blinked. "What?"

"Yeah!" Rainbow said. "I mean, can you blame her?" She gestured to the six girls currently in their underwear. "We're, like, the hottest girls in school! Guys would kill to see us like this!"

"It has gotten quite steamy tonight, hasn't it?" Rarity said. "Especially for your first slumber party. Poor thing, this must all be overwhelming."

"It usually never gets this hot!" Pinkie said. "But it's been so much fun maybe it'll become a more regular thing!"

"I can't really blame anyone for having urges like that with all of this going on," Applejack said. "I'll admit, I was quite close to doing it myself when we got those stripteases."

"Same!" Rainbow said. "I'm glad I'm not the only one!"

"Don't feel ashamed, darling," Rarity said. "Although, you look so pale right now. Are you well?"

Twilight clenched her teeth. Health-wise, she was fine. Anatomy-wise, she was as far from "well" as she could possibly be. Rarity got closer and felt her forehead.

"Goodness, you're burning up!" Rarity said.

"I'm not sick or anything," Twilight said.

"Are you sure?" Fluttershy asked. "You haven't said a single word tonight until now."

"I promise, I'm fine," Twilight said. "I just… have a lot on my mind."

"Like what?" Fluttershy asked. "Do you want to talk at all?"

"Um… well… it's complicated," Twilight said.

"If you want to talk about something, we'll listen," Sunset said.

"Wait…" Applejack said, moving closer to Twilight. "Do you have something in your pants? I thought I saw a bump."

Twilight's heart dropped, her heartrate skyrocketing to dangerous levels.

"Nope! Nothing in there! Just empty pockets!" Twilight said.

"Sure are sweating a lot," Applejack said. "Sorry, Twi. I don't believe you."

Twilight gulped as Applejack eyed her down. She watched as Applejack's hand reached to touch the bump in her pants. When Twilight instinctively tried to get away, Applejack immediately went for it. When her hand touched it, Twilight involuntarily gasped, and her heart dropped. Applejack's eyes went wide, and immediately grabbed Twilight's waistband.

"No!!!" Twilight screamed, but it was too late.

GASP!!!

Twilight could hardly breathe. She felt the air hit it, and she knew that her secret was now exposed. Applejack had pulled her underwear down with her pants, leaving her completely bare. Her member was now visible for all the girls to see.

"What in tarnation?!" Applejack beckoned.

Twilight bit her lip. "That. That's why I've had a lot on my mind."

All the girls just stared at Twilight's endowment, everyone blushing brightly.

"Um… s-sorry, sugarcube," Applejack said. "Guess my curiosity got the best of me."

"Twilight! You have a penis?!!!" Rainbow yelled.

Twilight sighed. "Yeah. I-I do."

"Is that why you were so bunched up with your legs, darling?" Rarity asked, to which Twilight nodded.

"I-It's so big," Fluttershy said, blushing profusely.

"You have some sexy legs, though," Pinkie said, trying to cheer Twilight up.

Twilight tried to hide her face in her ponytail. She instinctively closed her legs, trying to conceal it as much as possible.

"How did that happen?" Sunset asked.

Twilight blinked. "Wait, you don't want me to leave? But I'm a freak!"

"Well, to be honest, with all the stuff we've encountered together, this isn't entirely implausible," Sunset said. "It's still really weird, though."

"We don't want you to leave!" Pinkie said, giving Twilight a hug. "You're still our best friend, even if you have a dick." Pinkie gave it a poke, to which Twilight moved away.

"Um… d-don't touch it please," Twilight said. "I-It feels really weird when you do that."

"But Twilight, how did that happen?" Sunset asked. "I’m so curious!"

"Well," Twilight said. "This is an experiment gone wrong. I've been trying to figure out how it happened all week. I was trying to make some drinkable performance booster cocktails, but… this happened instead."

"How long have you had it, darling?" Rarity asked.

"Just since Monday," Twilight said.

"Is that why you've been so quiet all week?" Rainbow asked.

Twilight nodded. "I wasn't sure what to make of it. And I wasn't sure what you girls would think of me. Besides, it was giving me… urges."

Applejack raised an eyebrow. "What kind of urges?"

Twilight blushed. "Um… well… it gets kind of excited around pretty girls… l-like you all…" The girls' eyes all widened. Fluttershy was blushing noticeably hard. "It gets really hard at the most inopportune times, and the only way to get rid of it is to… i-is to…"

"Masturbate?" Sunset said.

"Y-Yeah…" Twilight said. "I've felt so dirty this last week. I usually don't think like this. I've never gotten so… excited just from looking at you all. The only theory I have is that this new organ is causing a hormonal imbalance and… I get horny easily."

"Well, what about your female parts?" Sunset asked. "Do you still have those?"

"I seem to," Twilight said. "But again, I don't know why."

"Does it, like… work?" Sunset asked. "When you masturbate, do you finish and ejaculate?"

Twilight blushed and sighed. "…yeah."

"Is it fertile?" Sunset asked.

"I took a look, and it doesn't seem to be," Twilight said. "But that's about the scope of my knowledge. It works like a normal male reproductive organ should, but I don't know how I got it, much less how to safely get rid of it."

Twilight looked at all her friends. They seemed very confused by all of this, and they had every right to be. Has anyone else in the world had a problem like this? She couldn't exactly go to a doctor.

"Now my focus is entirely on finding a cure, so to speak," Twilight said. "I don't even know where to start, though. I feel like I'm gonna be stuck with this forever."

"Well we'll help you," Sunset said. "In any way we can. Right, girls?"

The girls nodded in agreement, and then Pinkie started walking towards Twilight.

"Did I hear you say that we turn you on?" Pinkie said, leaning on her hips and standing over Twilight.

Twilight noticed a small lilt in her voice, and a different look in her eye.

"Um… yeah," Twilight said.

"Mmm," Pinkie moaned. "You must've been going crazy tonight, haven't you?"

Twilight blushed. "Well… seeing you all in your underwear has been a bit much, you could say."

Pinkie grinned. "We caught your masturbating after Fluttershy was done. Tell me, have you been doing that all night?"

Twilight bit her lip. Pinkie had a certain look in her eye. The same kind of look Sunset and Rarity had when they were dancing.

"Well… um…" Twilight stammered.

"Y'all can tell us, sugarcube. We won't be mad," Applejack said. Everyone else smiled, reassuring Twilight that they agreed with Applejack.

Twilight took a deep breath. "Well… I started when Sunset was dancing. Sh-She just looked so sexy, and I had been getting hard while you, Rainbow, and Applejack were twerking. I just couldn't take it anymore. I needed some relief. Then Sunset stopped, but Rarity started dancing and… it started all over again. Then it came to such a high point when Fluttershy was showing herself off that a moan escaped. It's just… you're all so hot. I don't know if it was the dick causing it or not, but I felt like I had to. And when I started… I couldn't stop."

Fluttershy was blushing noticeably. Poor thing probably didn't know what to think now. All the other girls were a mix of confused and… interested? It was hard to tell. One thing was for sure. Pinkie was up to something. The look in her eye and the way she smiled at Twilight gave it

Pinkie nodded and went to grab her desk chair. She brought it over to wear Twilight was gestured for her to sit in it. Twilight did so, and just as she sat down Pinkie grabbed the bottom of her shirt.

"Hey!"

"We haven't seen what the rest of your body looks like," Pinkie said, pulling her shirt off, revealing Twilight's bra. Her underwear was a faded blue color made of satin.

"Ooh, y'all have a nice rack, Twi," Applejack said.

Twilight blushed. "Th-Thanks. They're C's so… kind of average."

"But they're perky," Pinkie said. "And speaking of perky…" Pinkie then started to fondle her boobs right in front of Twilight, catching everyone off guard.

"Pinkie? What are you doing?" Rainbow asked.

Pinkie giggled. "I'm just showing off my body for Twilight, since she can't seem to help herself in front of us." Pinkie used her arms to push her boobs up. "What do you think, Twi? Do you like them?" she asked, fondling them again.

"You trying to get her hard?" Applejack asked.

Pinkie blushed. "Maaaybe…" she turned around and started gyrating her hips to show off her butt. "How about this? Does this turn you on?"

"Pinkie, what are you trying to do?" Sunset asked.

"I just said! I want to make Twilight hard," Pinkie said.

"But darling, why?" Rarity asked, twirling her hair.

"Because! She's been horny basically all night!" Pinkie said, turning around to show off her boobs some more. "Haven't you, Twilight?"

Twilight blushed, biting her lip at seeing Pinkie dancing for her. "Y-You're not wrong…"

"Exactly!" Pinkie said. "And I bet all you want right now is relief, right?"

Twilight nodded without hesitation. "Oh yes, I would love some. I can just go to the bathroom real fast and…"

Pinkie pushed Twilight back onto the desk chair as she tried to get up.

"Oh no you don't!" Pinkie said with a big smile. "I got that chair out for a reason. I want you to sit back, watch me dance for you, and jerk off to me right here, right now!"

Everyone's eyes widened.

"Pinkie, are you sure…?" Sunset asked.

"Of course!" Pinkie said. "What's a hot, sexy girl like me supposed to do when her bestie is pent up?"

"Pinkie, I can just go the bathroom," Twilight said. "There's no need, really."

"Hmm," Pinkie pondered, "If you really don't want to stay, then why are you getting hard?"

Twilight bit her lip. She knew what was happening. She was getting hard. Fast. Pinkie turned around and showed her butt off again, doing the slow twerk that Sunset and Rarity did.

"Oh my," Fluttershy said. "I-It's getting so big."

Pinkie giggled. "Is my butt turning you on, Twilight? Ooooh, this is so fun!"

Twilight just watched in awe at Pinkie's jiggling pink rump, making her get harder and harder. She saw the rest of the girls just staring at it as it grew. Twilight could feel those perverted desires filling her mind again.

Pinkie grinned when she saw it wasn't growing anymore, meaning she had gotten it to full mast by with her dancing. She and turned around to fondle her boobs again. "Wow, Twi. Your cock is huge! You must really like my dancing."

"Damn, Twi!" Rainbow said. "That's gotta be… like… 9 inches long!"

"It's damn girthy too," Applejack said.

"An inch and a half in diameter, at least," Sunset said.

"It looks so smooth too," Rarity said.

"At least the accident endowed you well," Sunset said with a giggle.

Twilight blushed. "Th-Thanks."

Pinkie put her hands on her hips, showing her body off for Twilight with a grin on her face. She gestured toward Twilight's member.

"Pinkie… I-I still don't know…" Twilight said.

"Twilight," Pinkie said, in a much more seductive tone. "I want you to do it. Besides, I can see that you want it. You're looking at me the way some of the guys at school do when I wear a tight, revealing outfit. And I get that look a lot. You want relief, don't you? Your balls look so bloated. They must be sooooo full. Don't deny it, Twilight. You want me, don't you?"

Twilight clenched her teeth. She could deny it no longer. Pinkie looked so sexy, and just like with Sunset, Rarity, and Fluttershy, the same dirty thought crept into her mind… how can she not jerk off to someone so hot? The thoughts of Pinkie dancing with that perfectly sexy, thick, curvy body for her pleasure was just too good to pass up, whether it was Twilight herself, or her long, erect member doing the thinking. Twilight didn't care anymore. Her member was pulsating, and her balls were so swollen. She didn't just want release… she needed it.

Twilight nodded. "Yes, Pinkie. I-I need to get off so badly. And… ohhh… you look so sexy right now. I-I'll do it."

Pinkie squealed in delight. "Yay! I'm so excited! Sit back and relax, Twilight. I'm gonna get you off sooo good! Oh, and if you can, try not to cum too quickly okay? I want to have some fun with you…"
