Stuck Like Glue [Scat]

Luna sighed and poked at her jiggly stomach with her hoof. For 2 weeks her anus had been fused shut by a magical buttplug from the sadistic Discord. Not only had she gained a significant amount of weight from digesting her sister’s waste, she hadn’t been able to shit, now feeling bloated and in discomfort around the clock from the solid, chunky mass in her bowels. She looked at herself in the mirror. She liked what the situation had done for her ass, making it nice and chubby and plump, but lamented how much fat went to the rest of her body.

She was moping around in her room, wishing for an answer when she heard an opportune knock at her chamber door. Luna was surprised to see Celestia standing with her niece Cadence standing in the doorway. “Sister! We have wonderful news! I think we’ve found a way to unfuse that plug from your rectum. I’ve brought Cadence, because it is a powerful spell, and Twilight is out visiting her parents.”

“Hello, Aunt Luna. I hope you’re doing well- uh… as well as you can be, given your situation.” She gave her pudgy aunt a great big hug before she and Celestia got to work.

Celestia dropped a bag of books and tomes on Luna’s carpet with a “whump”. Luna’s bedroom soon looked like a tornado-wracked library. Eventually, Luna found herself standing in a chalk circle with Celestia at her front and Cadence at her rear. “Ok, Cadence, this spell requires your horn to be close to Luna’s posterior.”

“Right. Don’t worry, Auntie Luna, we’re going to help you out of this. Just think, only a few steps away from freedom.” Cadence lowered her horn above Luna’s ass, keeping her mouth a few inches away from the offending buttplug.

Following suit by Luna’s mouth, Celestia’s and Cadence’s horns glowed in unison as they began casting the spell. Their horns glowed brighter and brighter as they cast, and eventually the room was filled with another blinding bright light. Luna felt a sudden vacancy in her sphincter as she cleared her eyes. She tried to leap forward to hug her sister and thank her profusely for her help, but was met by a familiar tug on her anal folds.

Luna looked back and was met with a horrifically familiar sight, although with a major twist. The pink muzzle of her niece was firmly sandwiched between Luna’s thick blue cheeks. Around her newly unplugged anus was wrapped Cadence’s smooth, puffy lips, fused to Luna’s ponut in much the same way she and her sister had been conjoined weeks earlier.

“Oh dear,” Celestia whined, “Hold on, I’ll go get Twilight, this is an emergency.” Celestia shot out of the window with such force as to blow away the chalk circle and send books flying. Cadence tried to pull away from Luna’s hole, struggling out a muffled scream As Cadence kept tugging on her asshole, Luna couldn’t help but be confused as the struggle felt weirdly pleasurable to her.

Hours have passed since the mishap and Luna has started to feel her guts churning back to life, newly aware that their exit was no longer blocked. As time passed with Celestia a no-show, Luna’s and Cadence’s senses slowly became fogged by the spell that conjoined them. Manifesting first as blood rushing to their cheeks, Discord had dead-man’s-handed a magical aphrodisiac into Luna’s cursed buttplug.

As their cheeks burned, the princesses also felt a tingle start in their nethers before it turned into a burning neediness. Cadence could feel Luna’s asshole start to wink under her lips. Her mind clouded by Discord’s magic, Cadence pushed her muzzle into Luna and gave the thick royal ponut a few tentative prods with her tongue before giving it a full lick..

Still retaining barely enough power to resist the afrodisiac, Luna jumped as she felt Cadence’s tongue on her anus. “Cadence!” Luna chided her, “What art thou thinking? We art thine aunt; How couldst thou be attracted to this predicament?”

Barely answering Luna’s question, a muffled Cadence simply moaned, “Ohhhhmmmm,” as she deepened her licking into fully making out with her adoptive aunt’s ponut. Helpless to stop Cadence, Luna slowly started to accept her tongue. Luna even unknowingly started gently pressing back into Cadence’s muzzle as she licked.

Luna felt her stomach lightly gurgle. Cadence eyes widened as she wondered if this was it. “Ah, no worries, dear Cadence. ‘Tis but a small one. We can hold it in.” After a few more moments of the aphrodisiac attacking Cadence’s weaker senses and making her drip, she had better ideas. Her horn glowed and her magic tickled Luna’s belly as she started to massage her poor, bloated stomach.

Luna let out a cute little gasp. She was confused at the feeling, “Cadence… art thou trying to push out our gas?”

Cadence moaned, “Mmmmhmmmm,” and dug her tongue into Luna’s butthole, eliciting another gasp from her aunt.

Luna asked, “Why art thou trying to get us to release?” Cadence answered Luna by not answering her, simply deepening her massages of the royal stomach. Luna’s whimpers turned into moans as Cadence’s tongue prodded deep into her hole and her magic did its work on her. “Unf~. Cadence, please. Be careful, if thou continues, thou shalt make us-”

A hurricane of Luna’s flatus erupted from her ass, puffing up Cadence’s cheeks as it filled her lungs. Luna and Cadence respectively gave moans of relief and pleasure. As the giant gust of wind blew out of Luna’s ass, the magical aphrodisiac seized more of her will power, and she found herself losing control to it.

Luna’s pussy began to drip as her mind let the afrodisiac take the reins. “Mmm~, dost thou enjoy our derriere?” Cadence moaned in approval. “Good, because we may have more for a good girl like thou from where that came.” Luna gave her butt a gentle shake, wobbling her pudgy cheeks back and forth in Cadence’s face, giving her a good look of all the fat built upon Luna’s posterior.

Cadence playfully tugged on Luna’s hole, only going as far as her fused lips would allow her. The feeling of being stuck to her aunt’s ass only sent more arcs of pleasure through Cadence. Luna, fully enthralled by the afrodisiac, looked back to her niece and moaned, “Mmm~ Imagine what it would be like if we were to be conjoined like this permanently.”

Cadence practically leaked like a faucet as she heard her aunt make such lewd remarks, only enhanced as Luna’s horn glowed and Cadence felt her ponut being gently played with. The pleasure brought on by her anal massage made Cadence involuntarily fidget her hind legs in pleasure, wiggling her own butt as she writhed with Luna’s magic.

Luna let out a final, soft gust of wind in Cadence’s mouth, “Ooh, dearest Cadence, with all of thy stomaching massaging, the contents of our stomach have progressed rapidly, but they still appear to be stuck at the rear gate. Luckily for us…” Luna lit her horn and grabbed a small chest from her wardrobe, “we have emergency potions for the rapid disposal of unwanted waste.”

Hearing Luna use the word “disposal” in such a lewd manner turned Cadence’s faucet into a waterfall as her pussy gushed in anticipation. Opening the box, Luna raised an eyebrow. “Peculier, there seems to be a bottle missing from last we…” Luna thought back to the predicament she and her sister had been in only a few weeks earlier. “Oh, Discord, thou serpent, that’s how thou did it.” Luna wiggled her ass again, uncorking the small potion bottle. She turned to Cadence and asked, “Ready, dear?”

Cadence nodded her head and gave a muffled, “Mhm!”

Luna quickly chugged the bottle of laxative potion. “We’ll need to prepare you as well, dear.” Suddenly, Cadence felt a plug being inserted into her hole by Luna. Though small at first, it vibrated with fervor, tickling and pleasuring the inside of Cadence’s ass. The plug’s small appearance was deceiving as it rapidly grew, increasing the pressure in Cadence’s butt until it grew too large to pull out. Cadence playfully tugged on the vibrating plug for a few minutes until Luna’s big round belly violently churned.

Luna ripped a series of long farts that started airy but swiftly turned wet as Cadence swallowed them. These were mere appetizers for the main course that Cadence could feel careening through Luna’s gut. Luna bit her upper lip as Cadence put her forehooves on Luna’s pudgy ass, ready to receive her meal.

Luna let out a symphonic mixture of grunts and moans as she let her shit eject into Cadence’s muzzle. After the first few gulps of her aunt’s brownie batter, Cadence decided to get more comfortable and sat down on her soft haunches, still chubby from the baby weight. As Cadence sat there, she took what seemed like gallon after gallon of Luna’s mucky meal; her belly expanding as quickly as Luna’s deflated.

Cadence moved her hooves from Luna’s cheeks to her own belly as she felt her stomach expand further than it ever had before, even when she was pregnant with Flurry. Cadence lustfully moaned as her stomach kept on expanding from Luna’s flood of shit. “Mmm~ Does our niece enjoy receiving the, unf~ royal excrement? Ahhhhh~” Cadence could only let out a simple moan of pleasure as her eyes rolled back in her head.

As Luna’s torrential mudslide slowed into a trickle interspersed with wet puffs of her gas, Cadence was caught off guard and let out a sultry moan as Luna backed up and gently planted her soft, chubby cheeks on her face. Cadence swallowed the last few dollops of Luna’s shit and graciously began licking her hole clean. “Ah, thank you sweetie. A good girl knows to lick her plate clean.”

Luna took notice of Cadence’s newly bloated stomach and began to rub and knead it with her hooves. “Oh Cadence, we didn’t know thou wast expecting. It appears as though young Flurry can look forward to two beautiful siblings, by the size of thy stomach.” As she grinded her ass into Cadence’s face, Luna lent down and put an ear to her niece’s belly, listening to her waste find its new home. Gyyyourrrgh.

After kissing and nuzzling Cadence’s stomach, Luna moved forward and helped Cadence to her hooves. “Come dear, thou shall need to get used to the weight.” Luna looked through her legs at the hanging mass of Cadence’s belly, knowing that in time, it would become more padding for Cadence.

10 minutes passed of Cadence continuing to rim Luna until Celestia flew back in through the window. “Oh Sister! I’ve returned with Twi…” Celestia stopped dead in her tracks. She gazed upon her sister’s newly deflated, pudgy form and Cadence standing with a belly the same size as Luna’s had once been. “...Light. Oh dear, I was too late.” Celestia could smell sex in the air as she saw clear puddles between Cadence and Luna’s hindhoofs. “Luna… what did you do?”

“Oh, just some fooling around, dear sister. We think the outcome of our actions is quite clear.” Luna used her magic to jiggle and knead Cadence’s stomach, milking a moan from her.

As Twilight came into the room, her face was twisted with shock, “WHAT IN TARTARUS HAPPENED HERE?”

Cadence gave a muffled moan of pleasure from Luna’s rear, “Ahhhhhnnnnn~”

Twilight turned to Luna, “Is she… turned on right now?”

“Well, it all started a few weeks-”

“Abupbubup, never mind, I don’t wanna know. Let’s just fix this before anything worse happens.” Cadence kept rimming Luna as Twilight and Celestia reprepared their spell circle. They lined up at either end of the conjoined ponies. Another bright light from their spells filled the room and the princesses rubbed their eyes.

Cadence put her hoof up to her freshly separated lips, “Awwww” She still frantically licked Luna’s butthole as Celestia leaned on the wardrobe.

“Phew, I am glad that’s over. I wish I could help you with the waste but-”

“No no,” Cadence waved her hoof at Celestia, “I think it would be easier to just let it be.” Cadence went back to licking Luna’s moon crater before Twilight pulled her off again.

“Would you stop doing that?” Twilight asked as she sat Cadence next to Luna.

Luna teasingly poked Cadence’s jiggly belly and whispered in her ear, “Don’t worry, we have a plan.” She turned to her sister, “Cadence may reside in our chambers for a few days whilst she digests her meal. It would be best not to give her a laxative and ruin the plumbing.”

Twilight gagged in disgust, “Would you please not call it ‘digesting her meal?’ That’s so gross.”

“Aw, what seems to be the problem, Twilight? Can thou not handle the royal banter?” Luna and Cadence giggled to each other.

Twilight threw up her head and wings, “Ugh, road apples to this, I’m out. Thanks for pulling me away from my parents to deal with this mess.” Twilight stormed out of Luna’s chambers, just leaving the aunts and their niece.

Celestia also turned towards the door, “I’ll just let you be while I retire to my chambers. Good night, Luna. Good night, Cadence.

After Luna raised the moon, she and Cadence lay on the bed in a 69 position. It was time for Cadence to go to bed, and Luna needed a nap after the excitement of the day’s events. Luna put her head on Cadence’s bloated stomach, full of her food babies, like a pillow. Cadence opted to stick her muzzle into Luna’s nethers once again.

Luna teased Cadence, “Looks like we will have a late night snack.” Using her magic, Luna both shrank the plug slightly and gently spread her own hole for Cadence. Luna tugged and the plug slipped out with a satisfying pop, the batteries having died long ago. With Cadence softly licking Luna’s ponut, and Luna listening to Cadence’s bubbly lullaby, they both drifted to sleep, content in each other’s embrace, as well as the permanent scat fetish with which the afrodisiac had bid them “adieu”.
