Moonlight Diaper Diatribes

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.
