The only chapter

“La la la la laaaaaaa, la la la la laaa.”

Fluttershy's demure voice echoed in the quiet morning. She sang to herself happily as she slowly cut through the soft summer breeze, only a few feet off the green grass. She loved drifting through Ponyville in the early morning hours and made sure to get up early every day to experience it. So many animals were just waking up and greeting the new day, while the nocturnal critters were busy returning to their homes to sleep away the day.

“I don’t know about this, are you sure it’s safe?”

“Of course it’s safe! It’s not exploding in my hoof or anything, is it featherbrain?”

Fluttershy halted her flight. She hated being around ponies who were arguing. Judging by the direction the voices were coming from, she guessed the two ponies were arguing from a cloud above her. She decided it would be best to stay as low as possible to the ground and not make a sound to keep from getting caught in their spat. As she flew lower to the ground her hooves scraped the ground. Unfortunately, her hooves hit something. She lost her balance and the next thing she knew, her head was rushing up to meet the ground.

"Ouch."

Fluttershy’s head swam with pain. Curious as to what happened, she glanced behind her and saw a tree branch on the ground, directly in the path she tried to land on.

“Hey, Fluttershy! Wait up!”

Fluttershy sighed. “Oh…ummm ok.” She knew it was too late to run away now. “Is something wrong Flitter?” she asked trying to smile at the Light-green maned pegasus.

“Oh, it’s nothing, I’m just trying to get Cloudchaser here to try my newest cupcake, but she’s such a downer!” Flitter replied giving Cloudchaser a glare. as they landed on the ground.

“No offense, Flitter, but after your idea of putting eggs on pizza, I think I’m justified," Cloudchaser replied, sticking her nose in the air.

Flitter stuck her tongue out at her sister and turned back to Fluttershy. “Well since Cloudchaser is being such a brat about it, I think you should have it.” Flitter said holding the cupcake outwards with a genuine smile.

Fluttershy stared at the cupcake curiously. The frosting looked like whitish blue glass, almost the same color as Cloudchaser’s mane. Despite some of Flitter’s previous food related disasters, dessert was usually something ponies could count on her to do right. Pinkie even paid for the exclusive rights to make her coconut cream and almond frosting. While her nervousness would usually keep her from trying something so new and unusual, the pressure of the beaming smile of the pony behind the cupcake was too much for her. She couldn’t just say no. What if Flitter got mad or sad because she rejected the cupcake?

“Oh, well, umm, thanks. I’d love to try it out," Fluttershy said as she took the glassy cupcake into her own hooves. She saw Flitter’s eyes brighten and widen as she brought the cupcake to her mouth and took a small bite.

“Wha? Huh?” The yellow pegasus nearly dropped the cupcake in surprise. She could taste a sweet and almost tangy flavor on her tongue, but it didn’t feel like anything actually touched her tongue. She took another hesitant bite and was once again rewarded with the sweet flavor, but again, felt nothing on her tongue. The taste itself was almost like lime and blueberries, it was something she could truly say she had never tasted before. Satisfied with the taste, she started in on the rest of the cupcake taking large mouthfuls at a time and savoring the flavor of the unusual treat.

Flitter nudged her sister in the side. “See? I told you it was perfectly fine! Fluttershy seems to like it.”

“Mmmm, oh yes, I do, it tastes lovely,” The yellow pony pitched in. Even though she didn’t really feel anything on her tongue, she still felt the need to swallow the bites she pulled off with her teeth. Mere moments later, the cupcake was completely gone, bits of the frosting lingering on her hoof until she licked them off.

“That was lovely. You should see if Pinkie would make it. I’m sure everypony would love it.” Fluttershy enthused.

“Hah! See? I told you it’d be a big hit!” Flitter said sticking her tongue out towards Cloudchaser.

“Urrrp!” Fluttershy’s face turned a brilliant shade of red. “Oh dear! I’m so, so, sorry! That was awfully rude of me,” the pegasus apologized. She felt a bit of pressure on her back and flapped her wings to try and relieve it.

“Oh Celestia, Flitter, what’s happening to her wings?” Cloudchaser asked, pointing to Fluttershy.

Fluttershy glanced back at her wings and nearly fell over in shock. Her wings had swollen up like large feathery balloons on her back preventing them from even flapping correctly.

“Forget her wings, what's wrong with her belly?” Flitter asked.

Fluttershy shot a panicked glance below her and spotted her belly bloating outwards at a frightening pace towards the ground.

“Oh no, oh my, heeeeelp!” She tried to scream. She tried to run away but realized her legs were no longer touching the ground. She flailed her hooves uselessly in a vain effort to try and go somewhere, anywhere to get away.

“Flitter you dolt, what was in that frosting?” Cloudchaser asked, grabbing her sister by the head.

“It's all safe! I promise! Just water, sugar, cream, and those funny blueberries at the edge of the Everfree Forest!”

Cloudchaser face-hoofed, “You idiot! Those are hyper oxygenated berries! They collect air as they grow and release it all right after they start rotting!”

Flitter pushed her hooves away defensively, “They’re tiny berries! They can’t hold that much oxygen!” She said pointing towards Fluttershy, who was rapidly billowing outward into a sphere.

“They don’t hold much air unless you mix them with water! Then they collect a lot more air!”

“Oh… ummm, how much air are we talking here?” Flitter asked nervously.

“Like, a lot. I used to put a single berry into a balloon with some water when I was a filly and it would pop.”

“But I already mixed them with water! They should have already released all their air!”

“Not if you kept the frosting in the fridge. It’s the heat that makes them release it.”

“Like the heat in Fluttershy’s belly.” Flitter said bringing her hoof to her face.

“Ummm! Excuse me, Cloudchaser! You seem to know a lot about these berries, how big do you think I’ll get?” Fluttershy asked nervously.

Cloudchaser shook the grayish pegasus frantically, “Quick! How many berries did you use in that frosting?”

Flitter’s eyes went up as she counted to herself. “Uhhhhh maybe sixty? Eighty?”

Cloudchaser’s face paled. She ran over to Fluttershy’s bloating form and tried to get a grip on the billowing pegasus.

“Cloudchaser, what are you doing?” Flitter asked

“Help me get her into the clouds so we can hide her! When she’s done growing, even a blade of grass might pop her!”

Fluttershy gulped at hearing this. She felt them trying to wrap their hooves around her swelling form to do Celestia knows what with her. She felt their hooves sink into her ballooning form as she grew bigger and bigger by the second. The ground started moving away from her as she felt herself being lifted by the two pegasi headed further into the sky. She wasn’t sure how much she had grown by this point as they moved toward a large patch of clouds, but considering she couldn’t even feel her hooves anymore, she was quite sure she had gone beyond any of the balloons she’d seen the pegasi launch for their research. Once they entered the cloud cover, she felt the hooves touching her pull away as she bounced softly on the fluffy white clouds.

“She should be safe here!”

“Uhh, hello? Flitter? Cloudchaser? Where are you?” Fluttershy gasped. She felt a heat rising inside her. A heat she had only experienced or indulged in when she was alone.

No, please. Not now...

"Is she alright?" Flitter asked.

"Well, she's probably going to grow a bit bigger due to the altitude," Cloudchaser explained.

"No, I mean her face. She looks really uncomfortable."

Uncomfortable was an understatement. Fluttershy's taut skin felt super sensitive to the touch, and the two sisters were doing a lot of touching.

"Shut up and help me pack some clouds around her so no pony can see," Cloudchaser said as she built a cloud fort around the expanding pony.

Sighing in resignation, Flitter buzzed over to a nearby cloud and dragged it back to Fluttershy's blimping form. Just as she was about to cover Fluttershy with some of it, her eyes landed on the pony's marehood.

"What the hay? Lookit this!"

Flitter peeked around Fluttershy's body at her sister. "What now?"

"I think there's something wrong!"

Flitter groaned and flew over to where her sister stood. Cloudchaser pointed her hoof directly at Fluttershy's marehood.

"Woah!" Flitter exclaimed.

The sisters stared at Fluttershy's vagina which seemed to have undergone an unusual transformation. Her lips were swollen and puffy, dripping like a leaking dam, threatening to burst with arousal. Her clitoris too, was engorged and now several inches long.

Flitter reached out and gently touched Fluttershy's swollen genitals. The bloated pegasus let out a squeal, causing her massive body to quake slightly.

"Don't do that!" Cloudchaser shouted, scolding her sister.

"Mmm, no! More! Please!" Fluttershy begged.

"You think maybe that's why she's making the funny sounds, Flitter asked, rubbing the tight skin near Fluttershy's swollen marehood.

"I guess so."

Grinning, Flitter flapped her wings and landed gently on Fluttershy's rounded body.

"What the heck do you think you're doing?" Cloudchaser asked.

Lowering her own crotch to Fluttershy's, she gave her sister a mischevious grin. "I'm going to relieve the pressure."

Cloudchaser groaned. "Gross."

Ignoring her sister, Flitter started grinding her lips against Fluttershy's, making the balloon-like pony gasp. Her skin wobbled and jiggled while Flitter went to work, rubbing against Fluttershy's swollen mare parts.

"Uhh Flitter? Maybe you should stop..." Cloudchaser warned.

"Don't be such a -huff- such a prude," Flitter said, between gasps of her own.

Cloudchaser's eyes widened as she stared at Fluttershy. With each gasp and pleasured moan, the bloated pegasus grew larger, her body expanding even further. By now, Fluttershy' ballooning form was more than ten feet tall. Unaware of this development, Flitter continued humping Fluttershy, clinging to her rounded body.

"Holy hell, this feels amazing!" Flitter exclaimed. She reached down and rubbed her hoof between their wet lips. She slowed her grinding when she felt something unusual.

"What the... is this her clit?"

Looking down, Flitter realized that Fluttershy's clitoris had swollen several more inches. Puffy, throbbing, and engorged with blood, Flitter got an idea. She angled her pussy up with it, and slide the clit inside her wet vagina.

"AHHHHhhhaaaaahmph!" Fluttershy cried out. Unfortunately, her cheeks had swollen to the point where she could no longer speak.

"Uhhh Flitter... I think she might be about to blow!"

"I know I am!" Flitter yelled back as she rode Flutershy's swollen nub. It expanded inside her, filling her tight canal and pushing her to the edge.

Fluttershy closed her eyes due to the immense pressure. Cloudchaser poked her and found no give. "Flitter! She's gonna pop!"

Flitter humped Fluttershy wildly, each bounce making a screeching or creaky noise as the fluid lubricated their wild love making.

"Mmmmmnyaaaaaaaaah!" Flitter screamed. Her lips spasmed, spilling juice all over Fluttershy's crotch.

*Boomf!*

Cloudchaser and Flitter fell onto the cloud. Flitter was still panting heavily in the glow of a most intense orgasm.

"Wh-where's Fluttershy?" Cloudchaser asked, panicking.

Flitter pointed to the middle of the cloud where the yellow pegasus lay curled up, panting in exhaustion.

"Fluttershy! Are you okay?" Cloudchaser asked, rushing to her side.

"Mmmmm, just wonderful..." the pegasus replied with a tired smile upon her face. Despite the strange ordeal, Fluttershy's body showed no sign damage, or lasting change. Even her marehood seemed to be back to normal.

Cloudchaser sighed and put her hoof to her face. "Flitter, you nut. You're lucky Fluttershy is ok. I guess your cupcake is a flop."

Flitter lifted her head and smiled at her sister. "Are you kidding? This wasn't a flop at all. This was the very first trial run for a new sexual aid, and Fluttershy is our very first testimonial. These things are gonna sell like crazy!"
