An Evil (Foalish) Sleepover

Queen Chrysalis paced the floor in front of the front door of her Castle, waiting the arrival of her "special somepony". She was anxious for her to get there. She even let the changelings that were required to stay inside of the castle go. Chrysalis, however, didn't receive a reply or notification from her mate, and was very terrified. Was she coming?

Chrysalis kept pacing the floor, really hoping she would get there. Then, she saw a blue glow under her door frame, and then a blue horn inside of the hole that unlocks the door. A blue aura opened the door and Chrysalis smiled as her mate stood in the door frame. Nightmare Moon was there.

"Moonie!", she said, hugging her marefriend, "You came!"

"Of course we did, Chrysie", Nightmare Moon said, "We wouldn't miss a sleepover with our marefriend".

"Moonie", Chrysalis said, "You know I don't like the royal 'we' speech. Could you please talk normal?"

"Oh, silly me!", Nightmare said, "I forgot you don't like it". She kissed Chrysalis' muzzle, making her blush.

"So, come in!" Chrysalis moved over so Nightmare could enter. Closing and locking the door with her horn, Chrysalis looked at Nightmare. "Did you bring..." She looked from side to side before finishing. "the supplies?"

"I did", Nightmare said. She pulled out a large, blue bag. Chrysalis smiled.

"Great! So, should we?"

"Not yet, Chrysie. I want to save the 'fun' for last".

"Aww..."

"Don't worry, Sweetheart. We'll start with the 'fun' in about two hours, OK?"

"OK, Moonie". Chrysalis hugged her marefriend and smiled.

"So... what do you want to do first?"

"I was thinking we could start off with some snacks and some catching-up, since we have to wait for the best part".

"Sounds good".

About four minutes later, Nightmare and Chrysalis were sitting on a huge rug, enjoying assorted cakes, cookies, pies, brownies, and ice cream, and talking randomly.

"So", Chrysalis said, stuffing a brownie into her face and swallowing, "How has it been up there in the Moon?"

"Well...", Nightmare said, shoving a huge spoonful of ice cream into her mouth. "It's not bad. It gives me peace from my nagging older sister. She actually did me a favor".

"That good, huh?"

"Yes. I still have 500 years of this, then I'm going to kill her. Thanks again for allowing me to enter your Changeling Kingdom".

"Not a problem. I couldn't just let you stay up there for a full 1000 years, could I?"

"I guess not. I tried the Griffon Kingdom first, but the King tried to touch my private area and I broke his wing and tore off his beak".

"Is he OK?"

"He's fine. He has healed and his beak is stitched on".

"Good". Chrysalis reached for some of her ice cream, but realized her favorite flavor was gone. "Umm... Moonie?"

"Yes?"

"Can I have the rest of your vanilla-oat-swirl, please?"

"Sure... for the rest of your chocolate-hay-crunch".

"Deal!" They traded flavors and continued to talk.

"So, how have you been, Chrysie?"

"Fine. I've been watching over my subjects, and think about ways to take over Equestria".

"You would share it with me if you were successful, wouldn't you?"

"Of course I would, Sweetie. I couldn't share something so big with anyone else".

"How do you plan on doing it?"

"Well... I was thinking I could impersonate that pink alicorn and take over her wedding in a few hundred years".

"You mean my daughter?"

"Oh... well, I could find something else".

"No no, that sounds like it could work. I'm already very upset at the fact that my sister is controlling my beautiful Moon! *growl* Damn you, Celestia!"

"Moonie, just wait 500 years and you'll have your revenge".

"I hope so. My sister is so much stronger than me with those bucking Elements of Harmony on her side. Now I'm a legend in a storybook, 'Mare in the Moon'"

"Must be very embarrassing".

"It is, Chrysie".

"Well, you have me, and I don't find the story embarrassing. In fact, I'd call it stupid if I had to give my opinion". Nightmare hugged Chrysalis.

"Thank you, Chrysie".

"You're welcome, Moonie".

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After the snacks, they sat down on the rug for a little grooming. Nightmare smiled as she used her hoof to hold some of Chrysalis' mane while using her magic to brush it.

"Am I brushing too hard?, she asked her.

"No, Moonie", Chrysalis said, "That feels really good".

"I'm glad you like it".

"Although, I'm still a little sad that we have to wait for the best part of the sleepover".

"Don't worry, Chrysie. In ten minutes, we can start".

"Good!"

"Now, can you brush my coat, please?"

"Of course I can".

Ten minutes later...

Nightmare and Chrysalis smiled as they put the brush and grooming supplies away. Then, the looked at each other.

"Is it time, yet?", Chrysalis asked.

"It is time", Nightmare said, "Just let me get the bag".

Nightmare grabbed the blue bag and set in in the middle of them. Unzipping the bag, the two alicorns stared at the contents of the bag, smiling.

The bag was full of foal items at the size for an adult.

"Everything looks so beautiful!", Chrysalis said.

"It does!", Nightmare said, "You don't know how many adult foal stores I had to shoplift from to get all of this".

"Hmph... It was definitely worth it".

"Sure was. So, want me to pad you first?"

"Yes, please!"

Chrysalis laid down on her back and opened her hind legs. Nightmare smiled as she levitated a thick, disposable, green diaper, foal powder, rash cream, and wipes out of the the bag. Nightmare opened the diaper placed it on the floor. Chrysalis raised her bottom so Nightmare could slip the back of the diaper under her flank. After getting the back of the diaper under Chrysalis, Nightmare grabbed a wipe and started to clean her marefriend's nether regions. Chrysalis shivered as the cold wipe rubbed against her marehood. After wiping her, Nightmare grabbed some cream and applied a huge glob on Chrysalis' marehood with her hoof. Then came the powder.

"The usual?", Nightmare asked, "Extra powder?"

Chrysalis nodded and Nightmare applied the powder onto Chrysalis' marehood. A lot of powder. After using nearly a quarter of bottle, Nightmare pulled the front of the diaper over Chrysalis' marehood and taped it up. Smiling at her work, she patted the front of the diaper.

"Do you want an onesie, too?", she asked Chrysalis.

"Yes, please", Chrysalis said, "I can't just be in a diaper, can I? I could freeze to death".

Nightmare chuckled and levitated a large, fluffy, green onesie from the bag. Chrysalis sat up, her diaper crinkling loudly as she did. Chrysalis raised her hooves up and Nightmare slipped the onesie on her. Chrysalis laid down again and Nightmare fastened the buttons to the flap that covered her diaper. After that, Chrysalis was ready.

"How do I look?", Chrysalis asked, sitting up on her diaper.

"You look so cute!", Nightmare said, kissing Chrysalis' muzzle, making her blush.

"Thank you, Moonie. So, can I do you now?"

"You can".

Nightmare laid down on her back and Chrysalis got a thick, disposable, blue diaper and the supplies. She opened the diaper and Nightmare raised her bottom, letting Chrysalis slip the diaper under her flank. Chrysalis started wiping her marefriend's nether regions with a wipe, making Nightmare shiver lightly. After cleaning her marehood, Chrysalis put the cream and extra powder on Nightmare's marehood. Then, she pulled the front of the diaper up over Nightmare's privates, taping it up.

"Now", Chrysalis said, "Let me get your onesie".

Chrysalis levitated a large, fluffy, blue onesie from the bag. Nightmare sat up, her diaper crinkling loudly as she did. Nightmare raised her hooves up and Chrysalis slid the onesie on her. Nightmare laid down again and Chrysalis fastened the buttons to the flap that covered her diaper. After that, Nightmare was ready.

"How do I look?", Nightmare asked, sitting up on her diaper.

"As cute as I do", Chrysalis said, kissing Nightmare's muzzle, making her blush.

"Thank you, Chrysie. So, now that we're padded and dressed, maybe we can start playtime?"

"Sure. Did you bring anything?"

"Of course I did". She levitated two plushies out of the bag. They looked very familiar. "I custom made them".

"Celestia and Cadence?"

"Yes". She gave Chrysalis the Cadence plushie and she kept the Celestia one. She then moved it up and down, making it look like it was talking.

"Luna!", the plushie said, "I will not fight you! You have to lower the Moon! It's your duty!" The joke made them both giggle lightly. Then, Chrysalis did the same.

"I'm Cadence", the plushie said, "I can make two ponies fall in love with a blast of magic, and I think I'm pretty". They giggled again.

"I banished my sister to the moon just because she wanted an eternal night because ponies play in my Daytime and sleep in her Nighttime. I'm now controlling her Moon and I have the whole Castle to myself. I'm probably sitting in my bedchamber right now, stuffing my face with cake and answering fan letters, with my fat ass hanging over the bed". They both howled with laughter.

"Sunshine, Sunshine, ladybugs awake! Clap your hooves and do a little shake!" She moved the plushie to mimic the actions, making them howl with laughter again. Then, Nightmare got an idea.

"Luna, my tail looks too long. Could you trim it for me?"

"Sure, Celestia", Nightmare said. She grabbed the plushie's tail with her teeth and completely tore it off, cotton coming with it. "Is that better?"

"Yes", the plushie said, "Thank you". Chrysalis developed a similar idea.

"Eww! My hooves look cracked!"

"Let me help you with that", Chrysalis said. One-by-one, she ripped the plushie's hooves off, bringing cotton with it. "Better?"

"Yes", the plushie said.

"Luna", the Celestia plushie said, "I don't like the way my mane looks".

"Oh, OK!", Nightmare said, ripping off the plushie's mane and more cotton.

"Queen Chrysalis", the Cadence plushie said, "My horn is too big".

"I'll take care of that", Chrysalis said, biting the plushie's horn off.

Soon, they both started tearing the plushies up, cotton spewing everywhere. Once nothing was left but pieces of cloth and cotton, they sighed loudly.

"That felt so good!", Nightmare said, cotton stuck in one of her fangs.

"It did!", Chrysalis said, cotton in her mane. Once they shook the cotton off of themselves, they cuddled together, sighing loudly.

"Mare...", Nightmare said, "We really are a couple of bastards, aren't we?"

"Yep", Chrysalis said, "The most evilest, and cutest, ones ever!" They let go of each other and sat on their diapers, relaxing for a bit. Then, their stomachs growled loudly.

"Looks like we could use some num-nums", Chrysalis said, "Did you bring any bottles?"

"I did not", Nightmare said, "but, I brought something even better".

"Better?"

Nightmare smiled as she levitated two tubes of liquid from the bag. Chrysalis starred at the liquid.

"What is it?"

"Oh... just a little... potion".

"What does it do?"

"Well, instead of drinking that chalky formula, I had an idea. This is a potion that can cause any mare to produce their own milk, as if they just had a foal".

"So you're saying that by drinking this, we could nurse?"

"Yes". That's when Chrysalis put two-and-two together.

"You want us to breastfeed each other?!"

"Yes".

"Why would you want to do that?!"

"It's always a good time to try something new".

"Well... it does seem pretty tempting".

"Then, why don't we do it?" Nightmare levitated own of the tubes to Chrysalis.

"OK... I'll do it". She took one of the tubes and quickly gulped down the liquid, as did Nightmare. Then, they stared at each other.

"So", Nightmare said, "Who's going first?"

"I'll go first", Chrysalis said, "I'll see if it worked".

Nightmare shrugged as she laid down on her side, like a lazy dog. Chrysalis laid on her stomach and stared Nightmare's nipples. She was starting to have second thoughts. Should she really do this? She finally worked up the courage and started suckling, feeling the warm, sweet, creamy milk run over her taste buds and into her throat, making her moan. After five minutes of nursing, Chrysalis had gotten enough.

"How was it?", Nightmare asked Chrysalis.

"That... was... awesome!", she said, "You're a genius! So, ready for me to nurse you?"

"Sure".

Chrysalis laid down on her side and Nightmare began suckling, filling her stomach with her marefriend's milk. After filling her stomach, she sat up again.

"Milky good", she said in a foalish voice.

"I told you", Chrysalis said, kissing her marefriend. Then...

"Uh oh! Potty!", they both said at the same time, feeling their bladders overflowing. They both looked at each other and smiled.

"On three?", Nightmare said.

"Yes", Chrysalis said, "One... two... three!"

They both released a long torrent of urine into their diapers.

"Ahhh...", Chrysalis said, feeling her warm liquid spray the front of her diaper.

"Oh yesss...", Nightmare said, feeling her warm liquid spraying the front of her diaper.

A muffled hissing noise rang out as they continued to wet their diapers. Their onesies started bulging out in the front as their diapers started expanding from absorbing so much urine. They continued for about another two minutes before finally finishing, sighing loudly.

"That felt soooo good!", Chrysalis said, "And I'm surprised our diapers didn't start leaking".

"Me too", Nightmare said, poking the front of her diaper, "I guess they're just that strong". Then, their stomachs growled again. "I'm still hungry".

"Me too", Chrysalis said.

"Time for the good stuff".

"You don't mean..."

"Oh, I mean". She levitated two jars of pureed foal food. Pureed Apple for Chrysalis, and Pureed Banana for herself. Chrysalis squealed in joy as she saw her favorite flavor.

"Moonie", she said, "How did you know?!"

"I always know what you like, Chrysie", Nightmare said, "So, should we start?"

"We should", Chrysalis said, "But, we wouldn't want to make a mess on the rug, would we?"

"Oh silly me. We need our bibs". She levitated a blue bib and a green bib from the bag and tied the green one around Chrysalis' neck and the blue one around her's.

They open their food jars and began eating, not even bothering to use any spoons. They just dipped their hooves into the sweet mush and sucked it off.

"It always tastes better every time I eat it", Nightmare said.

"That is true", Chrysalis said. She dipped her hoof and attempted to put some of the mush into her mouth, but it fell off and landed on her bib with a loud squishing sound. She blushed heavily. "Oopsie!"

"It's OK, Chrysie", Nightmare said, putting a hoofful of her mush into her mouth, "At least it didn't hit the floor".

"True". She went back to her mush.

After a few minutes, they finished their mushes. Nightmare took the jars and put them in the trash. She looked over at her marefriend, who had her delicious mush all over her face and bib.

"Oh, you dirty little filly", she said, "Let me clean you up". She used her tongue like a wipe, wiping the sweet mush off of her marefriend's face. After cleaning her face, she took off their bibs and put them away.

"Thank you, Moonie", Chrysalis said.

"You're welcome, Chrysie", Nightmare said, "So... crayons?"

"You know it!"

A few minutes later, they two adult foals were sitting down on the rug in their wet diapers, drawing random things. Then after a few more minutes, the both farted loudly. Hearing their windbreaks, they looked at each other, smiling.

"Should we?", Chrysalis said, another fart escaping her.

"We should", Nightmare said.

They both got into a squatting position and raised their tails. Grunting, they both concentrated on pushing, trying to mess their diapers.

Chrysalis' dam broke first as her anus dropped a massive log of horseapples into the back of her diaper and created a large bulge in her diaper. Then, Nightmare's dam broke, sending a slightly larger log of horseapples into the back of her diaper, and creating a larger bulge in her diaper. The smell of their mess started to fill the room. Then, they relaxed their bowels, sending much softer logs of horseapples into their diapers. They sighed as their manure flowed into their diapers with strong, pungent odors.

"This smells wonderful", Chrysalis said, feeling her squishy mess pile up in the back of her diaper. The back of their onesies started to expand as their massive loads built up in the back of their diapers. The relief of messing themselves felt really good, and they let their wings spread apart, feeling so good.

Their onesies continued to expand as their diapers filled with their manure. They really enjoyed the feeling of their warm, squishy, stinky mess filling their diapers. After defecating for another five minutes, they finally finished. Exerting themselves, they were able to let out a wet fart before sighing loudly.

"That was the most massive dump I've even taken", Nightmare said.

"Me too", Chrysalis said.

They looked at their and each other's diapers. Their diapers were holding more than four normal loads of manure. They were bulged out to the size of jumbo beach balls and could have be used as a beanbag. The very strong smell had taken over the entire room, but didn't effect the two alicorns. In fact, they were proud of their disgusting smells. It smelt awesome to them. They stood up, seeing how low their full diapers hung. Their messy diapers were so full, they hung to the point where they were about an inch off of the floor, and they were a little heavy. They smiled as they admired their work.

"So...", Chrysalis said, "Should we get changed?"

"No!", Nightmare said, "There's something I need to do first".

Nightmare sat back down, feeling her squishy, stinky mess squish against her flank. She opened her hind legs and poked the front of her diaper, feeling her warm urine she previously filled her diaper with splash against her marehood. Letting her tongue hang out of her mouth, she began to rub her diaper up and down into her marehood, moaning loudly. But then, Chrysalis walked over to her and slapped her hoof away.

"You're doing it wrong", she said, "I'll do it for you". She pressed her hoof into Nightmare's diaper and began to rub in circles, making Nightmare moan loudly. Nightmare pressed her hoof into Chrysalis' diaper and began to rub in circles. The two rubbed each other off, moaning loudly. Then, Chrysalis pulled Nightmare into a massive tongue-kiss, still rubbing her off. It wasn't long before their tongues began to wrestle each other as they continued to rub each other.

"OK, stop", Chrysalis said, "I've got a better idea. Turn around and present your rump toward me".

Nightmare gave her marefriend a kinky smile and a flirty wink before turning her padded, messy rump toward Chrysalis. Chrysalis reared up and mounted Nightmare. Letting her tongue hang out of her mouth, she began to thrust forward, slapping their diapers into their marehoods. Both Nightmare and Chrysalis clenched their teeth as their marehoods burned for relief.

"Oh, Chrysie!", Nightmare said, her voice quivering heavily, "I love you!" Chrysalis continued to thrust her marefriend.

"I love you too, Moonie!", Chrysalis said, her voice quivering.

Within minutes, they both moaned loudly, triggering powerful orgasms. They both released their love juices inside of their diapers, feeling their hot juices fill the front of their diapers. While their orgasms subsided, Chrysalis got off of Nightmare and they cuddled together, the fronts of their diapers touching. Nightmare rubbed Chrysalis' hard, green exoskeleton back as their orgasms ended.

"I love you, Moonie!", Chrysalis said as she licked her marefriend's muzzle.

"I love you too, Chrysie!", Nightmare said as she licked her marefriend's muzzle. The combined smells of sex, urine, and manure reached their muzzles.

"OK. Now, let's go get out of these rotten diapers and take a shower". They both flew up to the bathroom.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Nightmare and Chrysalis sighed as the hot shower water sprayed them. Nightmare grabbed the shower head and sprayed Chrysalis' marehood and flank, making her yelp a little. Then, Chrysalis did the same. After that, they started washing each other.

"Moonie", Chrysalis said as Nightmare sponged her exoskeleton down.

"Yes, Chrysie?", Nightmare said.

"I love having you around me. You make me feel so good!"

"So do you". Nightmare finished washing Chrysalis and Chrysalis started washing Nightmare After washing her marefriend, they got out and dried themselves off. Getting into fresh diapers and putting their onesies back on, they went into the kitchen to find a snack before going to bed.

Once they reached the kitchen, Nightmare grabbed a carton of chocolate-hay-crunch ice cream and Chrysalis grabbed a few donuts.

"We really are pigs, aren't we?", Chrysalis said, stuffing the donuts into her mouth.

"Yep", Nightmare said, dipping her hoof in the ice cream and sucking it off, "But, who's going to stop us from indulging?"

"Absolutely nopony!", Chrysalis said, "HAHAHAHAHA!!!!!!!"

"HAHAHAHAHA!!!!!!!"

"Wow. You've got a good evil laugh".

"Thank you. And so do you". They finished their snacks and went into the living room. They laid down on the rug and Nightmare levitated a blue and green wool blanket, that was big enough to hold two adults. Nightmare covered them up and kissed her marefriend one last time.

"I love you, Moonie", Chrysalis said, snuggling into her marefriend's coat.

"I love you too, Chrysie", Nightmare said, resting her head in top of Chrysalis'. They both fell asleep with smiles on their faces.
