Prologue

“Ohhhhh!” Rainbow Dash moaned as she rocked back and forth on her bed. Her hoof pressed firmly against the front of her diaper. She bit her lip gingerly as she felt the inside of her moist diaper press against her vagina.

She was often busy with Wonderbolts practice or helping her friends, so this was a rare occasion for her. Who knew how long it would be before she could indulge in her fetish again? Rainbow continued to masturbate in her diaper as she writhed on her bed in pleasurable orgasmic embrace.

Suddenly she began breathing heavily and rapidly as she approached her climax. Her hoof dug furiously into her diaper pressing the material tightly against her vagina, with that she let out a loud moan as her wetness excreted into her diaper. Rainbow sighed and pulled her blanket up around her, the warmth of her cum and diaper comforting her.

“Excuse me,” a voice said in the darkness.

Rainbow Dash sat up in her bed and turned on her bedside lamp. Princess Luna was standing in front of her with a blushing face. “Luna?! What are you doing here!”

“Sorry to disturb you, Rainbow Dash. Though actually I suppose I’m not actually here,” Luna said. “This is actually a dream.”

“A dream? You mean this whole thing was a dream?” Rainbow rubbed her forehead. “Hold on why are you here though?”

Luna let out a sigh before she spoke. “Truthfully...I happened to spot your dream and well I couldn’t help but take a look. You see, I have a diaper fetish as well.”

Rainbow gasped. “Really? You mean one of our princesses has a diaper fetish? No way!”

“It is true. I hope you can forgive me for my intrusion.”

“Uh yeah it’s okay,” Rainbow said. “Anyways is there something you want to talk about?”

Luna sheepishly looked away from Rainbow. “Over the years I’ve grown rather fond of you and the other girls. I see you as my own family now. And...as part of that I would be delighted to see nothing more than you and the rest of your friends wearing diapers and being taken care of in them. I also have a desire to take care of my own sister in a diaper, but that is a separate matter.”

Rainbow listened intently. “Uh well okay. But what exactly do you want me to do about it?”

“Well as a princess I can’t exactly walk up to anyone and ask them to begin wearing diapers for me. But...since you also share this fetish I would like to impart a magical power onto you. I will give you the ability to hypnotize anypony you stare into the eyes of and give them a diaper fetish and compel them to feel the need to be taken care of.”

“Wait, you can do that? Ah man that’s so awesome it’d be so hot to see them in diapers!” Rainbow said. “Wait if you have this power why can’t you just do it?”

Luna blushed again. “Truthfully I’m far too shy to attempt such a thing in their presence. I merely wish to see them in diapers, even if I cannot be directly present. So, in addition to the ability to hypnotize ponies I will give you an amulet that will peer into the minds of those you hypnotize and record all of the details there. Once you have finished hypnotizing all of your friends return the amulet to me.”

“Sounds fair enough to me,” Rainbow said.”

Luna smiled. “Good. When you wake up you will have the ability to hypnotize ponies into having a diaper fetish, and the amulet I spoke of will be at your bedside. Good luck, Rainbow Dash.”

With that Luna vanished and Rainbow Dash drifted off into a deep sleep. When she awoke she immediately checked for the amulet and found it on her nightstand. It was a diamond shaped red jewel attached to a chain. She put it around her neck and got ready for the morning.

Her first task was to decide who she should hypnotize today. Rarity? No, she wasn’t even in town today. Twilight Sparkle? No again she was in Canterlot giving a lecture. Pinkie Pie had gone with Fluttershy on a friendship mission yesterday and they probably weren’t back yet. That left Applejack. If she wasn’t at the farm today then Rainbow would have to wait until she got another chance. She could also use her powers on other ponies...but it’d probably be best to at least use it on her friends first. So, with that determination in mind Rainbow Dash headed off to Sweet Apple Acres.

Applejack

“Hey Applejack!” Rainbow Dash said as she approached her friend.

Applejack stopped bucking apple trees to look at the cyan colored mare. “Rainbow Dash! What brings you here this morning?”

“I just wanted to see a friend is all. Where’s Big Mac and Applebloom?” Rainbow said.

“They went into town to tell Filthy Rich we’ll be a week late with our apple cider shipment this month. But we’re working as hard as we can,” Applejack said. “Let’s chat inside over some apple juice why don’t we.”

Rainbow followed Applejack back to the house and sat across from her friend at the kitchen table. Applejack poured both of them a glass of apple juice before she sat down herself. Applejack removed her hat and placed it on the table, letting out a deep sigh.

“Sometimes I feel like I’m getting to old for this work. But here’s to hoping I have at least another twenty years I can do this!” Applejack raised her glass up before taking a sip. “Now, how are you doing, Rainbow Dash?”

“Really good actually. Things have been going great with the wonderbolts,” Rainbow said. “Hey Applejack?”

“Hmmm?” Applejack said. She looked at her friend in the eyes and a strange sensation washed over her. She began to feel woozy and almost fell out of her chair. When she snapped out of it she couldn’t remember what had happened.

“You okay, Applejack?” Rainbow asked. “You need my help?”

“Yeah...sugarcube I’m just fine. I think I should lie down for a bit is all,” Applejack said. “Maybe I really am getting to old for this.”

“I’ll help you to your bed,” Rainbow said as she steadied Applejack as they walked upstairs. Applejack crawled into bed and Rainbow turned off the light in her room.

Applejack suddenly felt very tired and she drifted off to sleep. Without warning she found herself in the middle of a dream. She was a sea captain during the middle of a storm. Waves crashed on top of the ship, soaking her. Though strangely she noticed that the water wasn’t cold like it should be. A warm sensation spread across her body and she felt soothed by it. Slowly she began to wake, and to her surprise she had wet the bed.

Quickly she got out from under her covers. “What in tarnation?” Applejack said. It had been more than twenty years since she last wet the bed. Back when she was still a filly and before Applebloom was born. Horrified she quickly stripped her bed of its covers. Thankfully she hadn’t ruined the mattress.

Applejack bumbled the soiled covers together and walked out of her room to downstairs. Applebloom, who was now a full grown mare, smiled at her sister as she walked into the room.

“Hey Applejack! Good to see you’re feeling better. Rainbow told us you felt ill this morning,” Applebloom said as she was cooking pancakes. Only now did Applejack see Rainbow Dash sitting at the kitchen table.

“I offered to help around the farm since I don’t have anything else to do right now. It’s the off season for the Wonderbolts and I don’t have to go back for training until next month,” Rainbow said.

Looking out the kitchen windows Applejack realized that she had slept all day and not done any work. “Dagnabit! I can’t believe I slept all day!”

Applebloom placed a plateful of pancakes in front of Rainbow. “Hey sis what are you doing with your sheets?”

Applejack blushed intensely. “Well...truthfully I had an accident while I was sleeping. I wet the bed.”

Applebloom looked surprised. “Really? Are you sure you’re not sick or something?”

“I’m fine Applebloom,” Applejack said. “It’s just...I don’t know.”

“You’ve been working to hard that’s what! You need to learn to take some time for yourself. You know what no more working on the farm for this week.”

“Applebloom! I can’t do that, there’s so much to be done!” Applejack said. “Besides Big Mac-”

“Big Mac had to go see Sugar Belle in the hospital, she’s become very ill suddenly. He wants to be by her side. No, no more work for this week. You should at least take that long to rest.”

“But you can’t be serious!” Applejack pleaded.

Rainbow butted into the conversation. “It’s no big deal Applejack. You said you’re getting older yourself. Me and Appplebloom can take care of the work on the farm. You should rest for a week. You need to conserve your strength. Just kick back and relax and let us do the work for you.”

Applejack sighed. “I suppose that’s not a bad idea. But only one week ya hear? No more than that.”

Applejack sat down at the kitchen table and began eating the pancakes Applebloom had made. She poured some apple sauce on top of them. While chewing she noticed that Rainbow Dash was wearing a necklace with a red jewel. “Where’d you get that?” Applejack asked pointing with her hoof at the necklace.

“Uh just something I found in CloudsDale. I thought it looked nice,” Rainbow said.

Applejack laughed. “I never thought you’d be the type to like jewelry.”

Rainbow chuckled as well. “Maybe I’m getting more in touch with my feminine side as I get older.”

After they finished eating Applejack left her bed sheets and blankets to soak in soapy water over night, the last bit of work Applebloom allowed her to do. Scared of wetting the bed again Applejack found herself sheepishly asking Rainbow Dash to buy some diapers for her to wear. She wasn’t exactly sure why she did it. It seemed like an extreme measure, but somehow the idea of wearing a diaper felt comforting to her.

When Rainbow came back from the store with diapers she was blushing intensely and didn’t look Applejack in the eye. “So, um do you need help changing?”

Applejack was taken aback by the comment, as she expected to simply put herself into a diaper. But it somehow felt right to have another pony change her.

“Yeah if you wouldn’t mind,” Applejack said. She laid down on her bed and Rainbow Dash unfurled the diaper and slit it under her butt. Rainbow sprinkled a generous amount of baby powder on her genitals before she taped the diaper snuggly shut. The diaper was a light bluish color with cutesy flowers printed across the top. It felt childish to her, but it was also comforting so she didn’t mind.

Rainbow pulled something out of a bag. “Here in case you want it,” she said placing a pacifier on the nightstand next to Applejack.
“What-I can’t believe you’d think I’d need that!” Applejack said.

Rainbow shrugged. “Hey I’m not the one who wet their bed.”

Applejack blushed at this and didn’t look at her friend as she exited her room. It was humiliating having to ware a diaper at her age, but once again it somehow comforted her. It wasn’t long until she began to suck gingerly on the pacifier and it lulled her to sleep.

In the morning she awoke to the comforting warmth of a wet diaper and smiled. It was gross in a way, but she felt secure knowing her accident was contained by her diaper. Applebloom knocked on the door before entering.

“Morning big sis,” Applebloom said. “Rainbow said you asked her to buy diapers last night. You wouldn’t be in need of a change would you?”

“Applebloom I’m a grown mare I can change my own soiled diaper if you must know!” Applejack said in a fluster, not even stopping to think that she admitted to having wet her diaper.

Applebloom shook her head. “No work this week remember. Even if it means you have to become my baby sister you’re not changing your own diaper. You got that?”

Applejack sighed. “Yes, Applebloom.”

Applejack laid back on her bed as Applebloom undid her diaper. The stench of pee wafted in the air and Applebloom quickly changed her sister’s diaper to rid it from the room. After this Applejack walked downstairs into the kitchen where she saw a high chair sitting at one end of the kitchen table.

“What in tarnation is that doing here?!” Applejack said.

Rainbow Dash spoke up. “I bought this also last night. To be honest...maybe acting like a baby for a week and getting pampered by your little sister will be good for you. Sometimes it’s just good to relax in a diaper.”

Applejack fumed at this. “There is no way I am going to act like a baby! I will not-” She didn't finish as Applebloom plugged her mouth with a bottle filled with apple cider.

“Enough of that! Rainbow Dash is right, you work yourself to hard. And if I’m being honest I think you’re rather cute in your diaper. I’d really like to take care of you as a baby sister. I think you’ll end up enjoying it more than you’d think anyways,” Applebloom said.
Applejack pulled the bottle out of her mouth. “To be honest there are worse things I could do for a week. Fine, I’ll try acting like a baby for a week. But don’t complain to me if you don’t like what that will entail.”

Applebloom laughed. “I think I can handle it sis. Oh and Sugar Belle will be fine, Big Mac should be back in a few days.”

Applejack reluctantly climbed into the high chair. Appleblom served her some mashed up apples which she began spoon feeding to Applejack. At first Applejack was angry and begrudgingly let her little sister feed her. Slowly though she began to relax and enjoy Applebloom taking care of her in this way. Without realizing it she had relaxed enough to wet her diaper again.

Rainbow Dash was the first to notice the smell and chime in. “I think Applejack wet her diaper again.”

“It seems she did. You wanna change her this time, Rainbow?” Applebloom said.

“Yeah no biggie,” Rainbow said. Applejack followed her back upstairs where she laid down on the bed again. Rainbow un taped her friends diaper and her mouth began to water at the site.

“Rainbow what are you doing?” Applejack asked. Following this Rainbow removed Applejack’s soiled diaper and rubbed it against her vagina. Despite the unexpected turn of events, Applejack couldn’t help but feel turned on herself. It wasn’t long until both mares had an orgasm at the same time.

Rainbow Dash quietly changed Applejack into a fresh diaper. After this Rainbow and Applebloom began work on the farm for the day until night time fell. In that time Applejack was given some baby toys by Rainbow and she played with them for the day. There was no initial reluctance this time however, she simply enjoyed acting as a foal would. It had only been a day since she wet the bed, but she was already completely content living her life as a baby from now on. It felt natural to her somehow, and it made her happy.

That night Rainbow Dash eyed Applejack suspiciously all night. Suddenly while they were earring Applejack felt a strong urge in her stomach. She let out a series of loud farts before her mess piled into her diaper causing her diaper to bulge.

“Jeez sis!” Applebloom said, though her demeanor quickly changed. She seemed very uncomfortable and her face became red as she blushed. “That’s...I really wanna change you sis.”

“Yeah,” Rainbow said, who seemed like she was gonna burst. “It’s just that-”
Applebloom finished the sentence for her. “You’re so fucking hot in that messy diaper sis! I wanna clena you up then fuck you so hard!”

Despite not expecting this outcome, it somehow felt natural to Applejack. Her vagina became moist at the though of Applebloom fucking her relentlesy alongside Rainbow Dash. With this they all walked upstairs into Applejack’s bedroom.

In a frenzy Rainbow Dash tore off Applejack’s messy diaper and disposed of it. Applebloom unceremonisuly began licking Applejack’s freshly wiped asshole. The nerves there were still tender after just messing and it made her moan deeply.

Suddenlt Rainbow plopped her rear on to Applejack’s face. To her surprise it was covered with a large diaper of the same kind Applejack wore. Instantly she began pressing her face into the diaper and despite how thick it was she could feel the moist vagina beneath. Rainbow Dash leaned her head forward as Applejack continued to massage her vagina and stuck her tongue into Applejack’s vagina, using one of her hooves to massage her cliterous.

Applebloom could feel her vagina dripping with wetness as she continued to stick her tongue deeper inside of Applejack’s asshole. It was warm and tight around her tongue, it felt inviting to her and she wished to dig deeper. To go as far as she could possibly go with her tongue in her sisters asshole. Applebloom reached a hoof down to her already dripping vagina and began to massage it with ferocity.

In what seemed like a brief instance where their minds became one, they all climaxed. Wet hot cum drained from the mares vaginas and pooled around them. Applejack’s cum dripped onto Appleblooms nose and some slipped on to her tongue. She loved the taste instantly and began to lick her sister clean.

Rainbow changed out of her diaper and helped Applebloom and Applejack clean up. They all felt awkward about what had just happened, but they also felt content. This was a good experience from them, and they resolved to try it again.

After this several days of diaper fucking between the three mares followed. At the end of it all Applejack smiled at her cyan colored friend.

“I suspect you had something to do with all of this?” Applejack said.

Rainbow looked away from her friend. “Well I mean obviously I was there wasn’t I?”

“Rainbow I am almost certain I did not have a diaper fetish prior to a week ago. Be honest with me.”

Rainbow sighed. “Luna gave me the ability to hypnotize ponies into having a diaper fetish. I used that power on you and Applebloom. Sorry.”

Applejack laughed. “I’ve never felt better in my life. You know what, I think our other friends could really use something like this. I think you should go and use it on them.”

“I mean I was gonna anyway. But you really think this is a good idea?” Rainbow said.

“Sure do. I have a feeling they’ll find it as helpful as I did. Good luck sugar cube.”

“Thanks, Applejack, “ Rainbow said before she flew off.

Applejack smiled before putting back in her pacifier as she waddled back inside. She looked forward to the many sex and diaper filled days she had ahead with her sister.

END OF CHAPTER ONE

Fluttershy

Fluttershy took in the cool morning air as she landed at her cottage. The friendship quest with Pinkie Pie had taken longer than expected and they’d only just got back in Ponyville. She was tired and decided to take a nap inside of her cottage. She snuggled up with her blanket and drifted off to sleep as the morning light seeped into her house.

She awoke to Angel angrily thumping his foot on the ground. Fluttershy smiled at the bunny and got out of bed to feed him. He barely registered her presence as he began to indulge in his food. Fluttershy saw that it was now midday, and she felt more well rested than before. A knock at the door startled her and she went to go answer it.

“Hey, Fluttershy,” Rainbow Dash said as the pink maned mare opened the door. “Mind if I come in?”
“Not at all Dashie!” Fluttershy said.

They sat down on the living room couch together. Fluttershy let out a yawn before she spoke. “Pinkie and I just got back from a friendship quest this morning. I took a nap in the meantime. How are you doing?”

“Good. Wonderbolts is going great,” Rainbow said. “I uh...spent last week helping Applejack at her farm.”

“Oh good, you know she can really work herself too hard sometimes.”

“Yeah,” Rainbow said, laughing. “Hey, Fluttershy?”

“Yes, Rainbow?” Fluttershy said. She turned to look at her friend and found herself staring intently into Rainbow’s eyes. Suddenly she couldn’t remember what she’d been doing.

“Fluttershy?” Rainbow said. Fluttershy didn’t register that her name was being spoken and it took multiple tries from Rainbow to snap her back to reality. Oops there goes gravity.

“Sorry. I zoned out for a second,” Fluttershy said. “I think I’m still tired from the trip. Perhaps I should lie down some more.”

“Hey nothing wrong with a good nap,” Rainbow said. “You sure you’ll be okay? I could stay until you feel more well rested.”

Fluttershy yawned before she answered. “Normally I wouldn’t want to trouble you, but I am rather tired right now. It would mean a lot if you could stay to help, Dashie.”

“No problem,” Rainbow said. With that Fluttershy wandered back to bed and snuggled up under the sheets once again. The next time she woke it was early morning the next day. She got out of bed and got ready for the morning by taking a warm bath and styling her mane.

“Morning sleepyhead,” Rainbow said as Fluttershy walked downstairs. “I made some pancakes for breakfast.”

“Thank you, Rainbow Dash. I’m grateful you helped out yesterday while I slept,” Fluttershy said.

“No problem,” Rainbow said as she put a plate of pancakes in front of Fluttershy on the kitchen table. Angel had already been given a carrot for the morning. Rainbow sat down across from Fluttershy with her own plate of pancakes.

“So, you slept good last night?” Rainbow asked.

“Yes, I really needed the rest.”

“Anything interesting happen while you slept?” Rainbow asked.

“No. Why do you ask?”

Rainbow coughed. “You didn’t wet the bed by any chance did you?”

“No, why would you ask such a thing?” Fluttershy said.

“No reason,” Rainbow said, stuffing her mouth with pancakes. Fluttershy was curious, but she decided not to press the issue. Rainbow probably had planned to prank Fluttershy in some way but it didn't pan out.

After finishing breakfast Fluttershy got ready to go out. “I need to do some shopping in town. Would you like to join me?”

“Sure, why not,” Rainbow said. With that they left the cottage and flew into Ponyville. It was lively in the early morning hours when most shops were starting to open. They browsed different stands and shops getting the various things Fluttershy needed for her cottage.

“Hey Fluttershy,” Rainbow said gesturing for her friend to stand by her. “Check this out.” Rainbow pointed at a onesie intended for a foal with a matching set of mittens and booties as well as a pacifier inside of a shop window. Fluttershy couldn’t help but stare at the ensemble and became entranced by it.

“Oh...I’d like to check inside here, if you don’t mind Dashie,” Fluttershy said, blushing.

“Not at all,” Rainbow said. They walked inside the store and found that it was completely dedicated to clothing for foals. There were a variety of onesies, bonnets, booties, pacifiers, bottles, all lined up across the store. Fluttershy walked around awestruck at all of it. She settled her eyes on a pink onesie with blue flowers printed on it. The design was strange since it was clearly too big for a foal...it felt like it would be just right for her.

Taking the outfit off the rack she went to go check out. Her eye caught a glimpse of something else foals wore. Diapers. Most were foal sized but she did notice there were ones clearly intended for adult ponies. She couldn’t help but be attracted to them and so she grabbed a boxful of them and went to check out. Rainbow Dash met her outside the store.

“Diapers?” Rainbow said.

“Well I uh...you see…” Fluttershy trailed off. “They seemed comforting.”

Rainbow smiled. “Hey I’ve been meaning to ask you something. Would you like me to take care of you for awhile?”

Fluttershy blushed at this. “Like...like as my mommy?”

Rainbow Dash was surprised by what her friend said but followed it up by smiling. “Yeah like your mommy.”

With that declaration in mind they both flew back to the cottage to get settled in. Angel getting tired of having Rainbow around decided to escort himself out and spend some time with Pinkie Pie. Rainbow took Fluttershy upstairs and changed her into a diaper. They were a soft green color with a yellow striped line going around the waist. There were also stars on the front that would disappear if the diaper got wet.

Rainbow applied some baby powder to Fluttershy’s genitals before taping the diaper shut. She then helped Fluttershy into the pink onesie and fastend the ends over the diaper. She then put the booties on Fluttershy’s hooves and gave her a pacifier. Before they flew back home Rainbow went back inside the store and bought some adult sized bottles for Fluttershy, along with some more diapers.

Fluttershy played with some toys she got from the store while Rainbow went downstairs to make lunch for them. Fluttershy sucked on her pacifier gingerly as she played with the blocks and other toys she had. She was relaxed and felt at ease in her diaper.

A though entered her mind that she felt ashamed of. She wanted Rainbow to watch her mess in her diaper. And while she was being changed for Rainbow to fuck her...The thought alone made a moistness enter her diaper. At first she thought she’d peed, but realizing she didn’t only made her more turned on.

Fluttershy began to rub her hoof into the front of her diaper, pressing down on her cliterous. She moaned lightly as she sucked on the pacifier. Her hoof continued to press harder and rub faster against her vagina until she realized Rainbow had entered her room. She stopped immediately and became flustered, looking away from her friend.

“Fluttershy…” Rainbow said, causing her friend to look at her. Rainbow was blushing intensely, and Fluttershy could see a liquid dripping down the blue mares back legs. Fluttershy felt an ache in her vagina at this sight, and moaned lightly as she gestured for Rainbow to come closer.

“Mommy I have to make a messy in my diaper,” Fluttershy said, in as cute a voice as she could muster. “Will mommy take care of me afterwards?”

“Mommy would love to take care of you, Fluttershy,” Rainbow said, her vagina becoming increasingly wet.

With that Fluttershy turned around and pressed her diaper into Rainbow’s face. Grunting loudly as she strained hard to push her load out, Rainbow began to masturbate furiously. Brrrt! A loud fart escaped from Fluttershy’s asshole and slammed into Rainbow’s face causing the blue mare to moan loudly.

In a big push Fluttershy released her mess into her diaper filling it completely and causing it to press into Rainbow’s face even deeper. The smell filled the room and drove Rainbow crazy. She ripped off Fluttershy’s messy diaper and began eating her friend’s vagina out.

Moans escaped from Fluttershy’s mouth as Rainbow continued to give her tongue an workout inside of the other mare. Rainbow used one hoof to massage Fluttershy’s cliterous while the used the other to massage her own. Sweat dripped from Rainbow’s face on to Fluttershy’s vagina causing the timid mare to moan with pleasure.

Soon they were both are their limit and they climaxed as they let out loud moans that echoed throughout the cottage. Fluttershy breathed in heavily and Rainbow sat up in a daze. It took a moment for both mares to compose themselves. Fluttershy still had her mess smeared across her bottom, as well as the messy diaper stinking up the room.

Rainbow changed Fluttershy into a clean diaper and made sure to clean her friend throughly. She then went outside to dispose of the soiled diaper. Rainbow let out a sigh when she walked back into her friends room.

“Listen Fluttershy I-” Rainbow said, but Fluttershy held up her hoof for Rainbow to stop.

“Is there any chance something similar happened with Applejack last week?” Fluttershy asked.

Rainbow was stunned but regained her composure. “Yeah. Actually...Luna gave me the ability to hypnotize ponies into having a diaper fetish…”

Fluttershy smiled. “Well I guess that makes sense. Thank you, Rainbow. That...that was a lot of fun.”

“Yeah,” Rainbow said.

Fluttershy blushed as she thought about what she was going to ask of her friend. “Rainbow...could you perhaps fuck me in a diaper in front of...Sweetie Belle?”

Rainbow raised an eyebrow. “Sweetie Belle? How old is she now nineteen? Why her?”

Fluttershy blushed. “As she got older and I’ve seen her grow up over the years...I thought she developed a rather nice butt. I’d like to see it in a diaper.”

Rainbow laughed. “Hell of a reason. Sure, I’ll fuck you in a diaper in front of her. Then you can fuck her in a diaper.”

Fluttershy smiled.

After this they waited a few days until they got a chance to have lunch with Sweetie Belle. Rainbow sat next to Fluttershy, who was wearing a diaper and onsie as well as sucking on a pacifier. When Sweetie Belle approached them at the restraunt she reluctantly sat down.

“Is something going on?” she asked.

Rainbow shrugged. “Eh fuck it with the preamble this time,” she said before staring intently into Sweetie Belle’s eyes. Sweetie Belle suddenly forgot what she was doing for a moment.

“Sorry,” Sweetie Belle said. “I think I have a headache. Anyways...why is Fluttershy...wearing a diaper…” She found herself trailing off as she became entranced with the diaper Fluttershy was wearing. She felt an intense jealousy and wanted to wear the diaper for herself.

“Sweetie Belle?” Rainbow said, holding up a diaper for the younger mare to inspect. Sweetie Belle grabbed it instantly and rubbed it against her cheek, feeling the soft material against her fur. She clumsily tried to diaper herself until Rainbow offered to do it for her. It felt right to have another pony take care of her this way.

Eventually the waiter arrived to take their orders. The mare serving them was clearly uncomfortable with two adult ponies acting like babies in front of her, but said nothing as she took their orders.

After Rainbow finished eating her meal she noticed Fluttershy was fidgeting in her seat. “What is it, Fluttershy?” Rainbow asked.

“Mommy I need to make a stinky,” Fluttershy said with a pouty face. Sweetie Belle felt a pang in her vagina as it slowly started to get wet.

Without further preamble Fluttershy grunted and braced herself against the table as she pushed a large mess into her diaper. It was big enough to unsap her onesie and began to sag considerably. Rainbow took her que and pulled Fluttershy up onto the table and began to tear off her diaper. She got to the moist dessert within and allowed her tongue to dig deep inside of Fluttershy.

Sweetie Belle found herself masturbating without realizing at first, but the sight before her seemed so natural and yet so hot at the same time she couldn’t help it. The mare who took their orders walked by and was horrified when she realized what was happening.

Fluttershy was laying on her back on the table with her vagina firmly stuck to Rainbow’s mouth. Sweetie Belle removed her diaper and positioned her flank on top of Fluttershy’s mouth. Fluttershy plunged her tongue into Sweetie Belle’s asshole, as Sweetie Belle began to massage her cliteros.

The mare alerted her manager as to what was going on and they immediately sent for some guards to come kick the mares out. Rainbow climaxed as she felt a sticky warmth slider down her tongue into her mouth. Sweetie Belle let out a fart on Fluttershy’s tongue as she felt her own joy dripping on the yellow mare's fur.
After this some Royal Guards from Canterlot kicked the mares out in disgust, and the ponies who saw them in a heap whispered before walking away with disgusted looks. The mares stood up and looked at one another.

Rainbow laughed. “Wanna go fuck, Rarity now?”

Sweetie Belle let out a light moan at the suggestion. “Rarity...I’ve wanted to fuck her for awhile actually.”

Fluttershy blushed. “I think it would be nice actually.”

Rainbow smiled. “Let’s go then.”

END OF CHAPTER 2

Rarity

Rarity hummed to herself as she sewed a new dress together to deliver to Canterlot boutique. Someone knocked on the door to Carousel Boutique, breaking her concentration. She went to answer the door.

“I’m terribly sorry but I’m closed at the moment. However if you would like to place an order I’d be more than happy to take it,” Rarity said, as she opened the door.

“Hey Rarity,” Sweetie Belle said. Rarity saw Rainbow Dash and Fluttershy standing behind her sister.

“Oh my you two are here as well? How are you? Do come in girls,” Rarity said, ushering her friends inside. Rarity prepared some tea for her friends and sat across each other in the sewing room. It wasn’t until now that Rarity realized both Sweetie Belle and Fluttershy were wearing diapers. Examining it more closely she saw Fluttershy was also wearing a onesie and was sucking on a pacifier.

Rarity immediatley blushed as a thought raced into her mind about her sister. “Well what brings you here, Rainbow, Fluttershy?”

Rainbow was going to speak, but Sweetie Belle beat her to it. “I wanna fuck you big sis!” Sweetie Belle said.

Rarity nearly dropped her tea cup, though to her own shame not for the reason she should have. Rarity eyed the diaper around Sweetie Belle’s crotch and shifted her flank around to hide her shame. “Excuse me, I’m not sure I heard you correctly,” Rarity said, trying to avoid eye contact with her sister.

“I wanna fuck you,” Sweetie Belle said. “We all wanna fuck you.”

Rarity tried to ignore what her sister said. “Lovely weather we’re having in Ponyville today aren’t we? Perhaps you and Fluttershy will do some flying later, Rainbow?”

“Fluttershy just fucked your sister an hour ago,” Rainbow said. “We wanna fuck you now.”

Rarity noticed Rainbow trying to stare at her and immediately averted her gaze. “I have no notion of what you speak of.”

Sweetie Belle jumped onto Rarity and turned her face towards hers. “Sis I’ve had a crush on you ever since I was a filly. I wanna have sex with you real bad. And Rainbow Dash and Fluttershy wanna have sex with you as well.”
Flustered by her sister being on top of her, Rarity attempted to slip away but instead caused herself and the chair she was sitting on to topple over. Sweetie Belle got up off of her sister. Rarity was laying on her back, and before she could stand up Sweetie Belle let out a gasp as she stared at her sister’s crotch. A puddle was slowly dripping from Rarity’s vagina.

“Big sis…” Sweetie Belle said.

Rarity let out a sigh as she stood up. “Truthfully I’ve had an interest in diapers for some years now. I...have long wanted to see you wear a diaper as an adult. Several times I dreamt of concocting a new clothing line involving diapers and have you model them for me...I banished all those thoughts eventually.”

Sweetie Belle smiled. “Big sis, you could have told me.”

“I suppose so,” Rarity said. “I apologize for causing such a fuss about this. If you are all still so inclined, I would love to indulge in sexual gratification with you.”

Rainbow Dash walked over to Rarity and Sweetie Belle. “Sorry this is more insurance,” she said, as she stared intently into Rarity’s eyes. Rarity blinked momentarily afterwards.

“Rainbow, what was that about just now?” Rarity asked.

Rainbow blushed. “Uhhhhhh...well I was gonna hypnotize you into having a diaper fetish. But I guess it doesn’t work if the pony already has that fetish.”

“Rather bold of you to admit that, I suppose. Thank you for your honesty, Rainbow Dash,” Rarity said. “Well I must say I haven’t done anything like this before. So, shall we begin?”

Fluttershy made a pouting noise. “Hungry!”

“Of course, darling. I could make lunch for all of us first?” Rarity said.

Rainbow shrugged. “May as well. I guess we worked up an appetite after the fucking we did at the restraunt.”

Rarity made a vegetable stew for her friends, which took around an hour to make, and was now ready to be served. Rarity put bowels on the kitchen table for herself and friends and served each of them a helping.
Rarity sipped on some wine as she ate. About halfway through the meal Rarity noticed a particular scent floating in the air. Immediately she blushed and tried to discern the source of the scent. Looking at Fluttershy’s diaper, who was sitting right next to her, she could see how yellow it had become, and how much it now sagged. Rarity shook involuntariy and had to avert her gaze from Fluttershy.

The smell still lingered in the air though and she found it irrestably tempting. Without hesitation she plunged her head into the front of Fluttershy’s diaper and inhaled the smell of pee as deeply as she could. Fluttershy tried to hold Rarity to her crotch, but the unicorn was able to break free.

Sweetie Belle looked at her sisters crotch. “Big sis, you’re wet again.”

Rarity blushed at this, but didn’t say anything in her defense.

“Let me clean it up,” Sweetie Belle said, as she got off her chair and crawled to Rarity. She began licking the wetness off the chair that had pooled from her sister. Eventually she worked her way to her sister’s vagina. She began to suck on Rarity’s cliteros as she massaged the inner part of her vagina with her hoof.

Deciding to move the activities upstairs they all made their way into Rarity’s bedroom. Rarity lied down on her back on the bed. Sweetie Belle plopped her diapered butt on top of her sister’s face. She bent forward and began eating her sister’s vagina once again. Fluttershy pressed her pee soaked diaper into Sweetie Belle’s face, and Rainbow flew above the other mares, and hovered above them as she masturbated.

They all let out moans of ecstasy and pleasure. There was no way the pleasure they experienced was being contained within the walls of the room. Any pony walking outside would be able to hear them as they continued to fuck one another.

Rarity’s face was intensely hot from how closely her sister pressed her diaper against it. Rarity shook violently as her sister continued to devour her vagina with her tongue. Sweetie Belle let out a small fart. The gas traveled from the diaper into Rarity’s nostrils, and at that moment her eyes rolled back in her head. She was in heaven being able to smell these private scents her sister had been keeping from her all these years.

Fluttershy with her pee soaked diaper began to grunt and push a mess into her diaper. A series of loud farts preceded her mess, which filled the back of her diaper in one loud plop. Sweetie Belle smelling Fluttershy’s mess pressed against her face couldn’t help but feel her vagina began to leak and quiver at Fluttershy’s private scent.

Sweetie Belle feeling her own release coming released a series of farts into her diaper. Each one shook Rarity violently and only made her closer to her climax. Sweetie Belle pushed a long turd into her diaper that slowly began to fill up and press against Rarity’s face even harder. Rarity nearly lost it from the smell of her sister’s mess.

All of the mares were at their limit. All at once the climaxed in a cacophony of body fluids and sound. Fluttershy felt her cum begin to leak out the sides of her diaper. Rarity felt her cum be slurped up by Sweetie Belle. Sweetie Belle could feel the wetness from her vagina seep through the mess in her diaper to dribble down Rarity’s throat. Suddenly it felt like it was raining in the room as Rainbow continuously squirted over all the other mares covering them in her cum. Exhausted she landed on the bed next Rarity.

Satisfied with their recent sexual excursion they all fell asleep.

The next morning Rarity made breakfast for them. It was early and no pony had gone out to shop in town yet. They all sat at the kitchen table and ate their breakfast still shaking off the exhaustion from the previous day’s sexual activities.

Rarity was nervous about what she was about to ask and put those fears aside. “Girls, would any of you perhaps be interested in heading over to Twilight’s castle...and hypnotizing Starlight Glimmer into wearing diapers?”

Sweetie Belle smiled. “I didn’t think you’d be so quick to wanna have other ponies join in on this.”

Rainbow laughed. “Sure, why not. I always thought Starlight was hot as fuck anyways, so it will be great to see her in a diaper.”

With that resolution in mind they all finished breakfast and headed off for the castle.

Starlight Glimmer was organizing books in the library when she heard some foot steps in the hallway. She turned around to see Rainbow Dash, Fluttershy, Rarity, and Sweetie Belle standing awkwardly across from her.

“Hey guys,” Starlight said, unsure what her friends were doing here. “Any reason you’re dropping by?”
“Uh...Starlight could you come closer?” Rainbow asked. Starlight eyed her suspiciously but apporahced anyways. It was only now she realized that all of her friends were wearing diapers, and Fluttershy in particular appeared very babyish. She shook her head thinking it was her imagination, but when she looked back her friends were still in diapers.

Starlight turned to Rainbow to ask a question but suddenly found herself entranced in Rainbow’s gaze. Momentarily stunned she regained her senses and realized Rainbow was using some sort of hypnosis magic. Starlight quickly cast a spell to protect her mind from Rainbow’s attempt at intrusion. She lit up her horn prepared to launch an attack.

“What’s going on here?! Why did you try and hypnotize me?” Starlight said, an edge of hostility in her voice.

“Calm down, dear,” Rarity said. “Rainbow was merely going to use her hypnosis on you to cause you to develop a diaper fetish.”

Starlight blinked momentarily, confused by the straight forward nature of Rarity’s response. “How did you get this magic, Rainbow?”

“From Luna. She gave it to me in a dream,” Rainbow said.

Starlight let her guard down and shook her head. “What exactly is going on here?”

“We...wanted to have sex with you while wearing diapers,” Fluttershy chimed in sheepishly.

Starlight laughed. “Well sorry guys a hypnotizing spell won’t work on me.” Thinking about it did bring an idea to Starlight’s mind. “Actually, there is one pony we could use it on to have a fun time.”

“Who might that be, darling?” Rarity asked.

“Trixie. She ends up lazing around the castle a lot and prevents me from getting work done. With a few modifications on my end I can make it so Trixie will become my very own diaper maid.”

“Diaper maid?” Rainbow said, rolling her eyes at the thought. “Isn’t the diaper enough?”

Starlight laughed. “Honestly I have somewhat of a fetish for maid outfits. Diapers...well I could learn to like it.”

“So, that’s our plan then, hypnotize Trixie next?” Rainbow said.
“Yeah just give me an hour to get everything ready. Trixie should be here by then,” Starlight said.

Trixie walked into the map room, flaunting her cape as she did so. “The great and powerful Trixie has finally arrived! Starlight, where are you?”

Starlight walked into the room. “Oh hey, Trixie. Our other friends are here as well.”

Trixie rolled her eyes as she sat on Rainbow’s chair. “You mean your other friends are here. Please don’t tell me you’re going to make me spend time with them? They’re so boring you know. It’s always more fun when we’re together by ourselves.”

Suddenly Rainbow Dash floated down from the ceiling in front of Trixie, staring intently into her eyes. At this moment Starlight cast her spell on Trixie turning her into a diaper maid. Suddenly Trixie felt the need to wear diapers and to clean everything in the castle. Starlight levitated a maid outfit over to Trixie, who hurriedly put it on along with a diaper. At this time Fluttershy, Rarity, and Sweetie Belle walked into the map room.

“What’s going on?” Trixie asked.

“We wanna fuck,” Rainbow said.

“Oh,” Trixie said. “Well why didn’t you say something!”

With that the activities began in earnest. Slightly embarrassed she was the only one not wearing a diaper, Starlight quickly padded herself up. Using a magic spell she was able to make so they were all now floating above the map table to make their sexual activities easier.

Rarity plopped her diaper butt on top of Sweetie Belle’s face. Starlight pushed her diapered butt into Rarity’s face. Trixie pushed her diapered butt into Starlight’s face. Rainbow pushed her diapered butt into Trixie’s face, and Fluttershy pushed her diapered butt into Rainbow’s face. They came around to form a circle with Fluttershy pushing her face into Sweetie Belle’s diapered butt.

It was a weird sensation for all of them but they managed to reach each other hooves into the pony in front of them’s diaper, and begin massaging their vagina for them. They spun around in mid-air as they continued to masturbaye one another in their diapers. Unbeknownst to the mares however Spike walked into the map room and was immediately stunned.
Instantly his dick became harder than rock. He couldn’t help but stroke his twelve inch dragon dick to the sight of his friends shoving their faces into each other’s diapers and masturbating each other. His dick pulsed as he gripped it in his hands stroking as fast as he could.

One by one the girls begin to feel the sensation of their bowels moving for release. Sweetie Belle released her mess almost instantly into Fluttershy’s face. Fluttershy, overwhelmed by the smell, slowly filled her diaper with her mess, pressing deeper and deeper into Rainbow Dash’s face until it was smothered by Fluttershy’s mess. Rainbow let out a few quick farts before pushing her mess into her diaper. Trixie inhaled the private scent of Rainbow’s mess deeply before she pushed her own load into her diaper. Her load was firm and long causing her diaper to sag and engulf Starlight’s face. Starlight nearly came from the scent of Trixie’s mess, but continued to concentrate on her own efforts. She pushed a small mess into her diaper along with some pee. Rarity couldn’t describe how good Starlight’s mess smelt, but controlled herself for her sister’s sake. With great effort Rarity pushed the largest and smelliest mess of all into her diaper completely engulfing Sweetie Belle’s head.

With that the final blow was struck. All mares came at once as they loudly screamed in joy into one another’s diapers. Spike couldn’t take it anymore and his dick erupted like a volcano exploding hot white cum all over the map room completely covering the mares from head to toe.

Spike fell onto his butt as the girls floated back down to the ground. His dick was still hard and standing firm. Rarity walked over to Spike and lightly probed his dick.

“Oh Spikey wikey, if only I’d known you would enjoy seeing me soil a diaper so much,” Rarity said, rubbing her messy diaper on Spike’s dick. It was still sensitive and came instantly covering Rarity’s smelly diaper in even more cum.

Shortly afterwards they call cleaned up and Starlight explained what was going on to Spike.

Without hesitation Spike asked a question of his friends. “Can we go see Twilight Sparkle in a diaper next?”

They all laughed. “Of course,” they said together. With that plan in mind they headed off to Canterlot to see Twilight.
