Chapter 1

Sunset Shimmer knelt on the cold floor of Canterlot Castle. Holding the fractured remains of her geode, she was trapped in human form while in Equestria. Princess Celestia’s voice boomed from her throne, “Sunset Shimmer, my former student, you should know better than anypony that stealing the Element of Magic is an unforgivable crime! For a crime so heinous, you deserve no better than death!” Sunset braced herself as she cowered beneath Celestia. “But… I will let you off easy.”

Sunset looked up at her former teacher through a blur of tears welled up in her eyes. “I.. I don’t understand.”

“I have a better idea for a proper punishment. Approach your princess.”

Sunset shakily walked towards Celestia’s throne and flinched as Celestia arose. Celestia was much taller than Sunset. Even in human form, Sunset was only just taller than Celestia’s hindquarters.

Practically straining her neck looking upwards, her gaze was met with Celestia’s stern visage. “As punishment for this high crime against Equestria…” Celestia turned around and pointed her ass at Sunset, “... will be to serve the royal posterior.” Celestia flicked her tail to the side, exposing her plump, juicy ponut.

Sunset stood in awe of what she was seeing. It had been so long since she had seen Celestia. Her rump was definitely larger than last she had seen her, all the cake that the royal diet demanded had obviously worked its way to her bottom; even her asshole was so plump it looked almost pudgy. She noticed Celestia’s stomach was larger as well. However, it didn’t so much look like she had gotten fat as she looked... bloated.

“Well? Get to serving.” Celestia’s booming voice snapped Sunset out of her thought. She hesitantly stepped closer to Celestia’s ass. Gently grabbing a flank in each hand, Sunset could tell how much the cake did to Celestia’s figure; her ass was divinely soft. Sunset’s fingers sunk a solid half-inch into Celestia’s flank fat as she looked at her punishment.

Celestia’s scent filled Sunset’s lungs as she took shaky, almost labored breaths. Celestia’s ponut winked with Sunset’s hot breath upon it, almost enticing her to it. She planted her lips onto Celestia’s asshole, giving a quick peck of a kiss. “Oh, I think you can do better than that.” Sunset gave Celestia’s asshole another kiss, this time passing her tongue past the rim of the royal ponut.

Celestia’s insides had a distinctly sweet flavor, one Sunset barely had time to savor as she pulled her tongue out of Celestia’s ass and licked her ponut like an icecream cone on a hot summer’s day. Sunset gently rubbed and squeezed Celestia’s flank. As she serviced and pleased Celestia, her clit violently winked, and she could just barely hear Celestia murmur as she savored the feeling of Sunset eating her ass. “Mmm… yeah.” Celestia’s breathing grew heavy and she sultrily moaned, “Ooh… suck it.”

Sunset’s fervent licking turned to passionate sucking. Taking the entirety of Celestia’s asshole in her mouth, Sunset sucked and pulled back, letting it out with a satisfying pop. Sunset gently licked and sucked Celestia’s asshole before going in for another hard suck. With lips fully around her ponut, Sunset sucked Celestia’s ass harder than a milkshake.

Just as Sunset was about to reach the tip of her sucking action, a long, airy blast of humid gas erupted into Sunset’s mouth. The sound was muffled, like a broken trombone blasting into a pillow. The taste of Celestia’s fart was acrid to the point of making Sunset’s eyes well up in tears not of sadness, but of sheer sensory overload. Not wanting to upset the mare whose hooves her life was in, Sunset dutifully swallowed all of Celestia’s fart. After swallowing Celestia’s gas, Sunset recoiled for a breath of fresher air.

Sunset’s breather was cut short, however, when she felt a familiar tingle on the back of her head. She looked up at Celestia and tensed up as she saw her horn glowing. “Truth be told, Sunset, I may have deceived you. Your service to the royal posterior was only the first part of your punishment; and I think it’s time for the second.” Sunset gulped as she was mortified wondering what Celestia meant.

She didn’t have to wonder for long, however. The tingling field of Celestia’s magic on the back of her head began slowly but firmly pushing Sunset towards Celestia’s ponut. “I’d advise you to take a deep breath, Sunset.” Celestia’s magic pressed Sunset’s face against her asshole. Celestia’s anal lips began to part as she magically pressed Sunset’s head harder and harder against her ass.

Despite the resistance, Sunset’s anal service had generously lubed Celestia’s hole with her spit. Sunset was up to her lips in Celestia’s ass. With one final push, Celestia forced the rest of Sunset’s head into her ass with a wet, sticky squelch. Celestia let out a sharp moan of pleasure as Sunset entered her ass and let out a sigh of relief as her thick pucker gently seated around her neck.

Sunset’s mind raced in the darkness of Celestia’s ass. She put her hands on Celestia’s flanks and tried to free herself, but like a finger trap, it seemed the harder she pushed, the more she got stuck. Celestia wasn’t even clenching to keep Sunset in, her ass did all the work. “Mmm, you can keep pulling sweetie. Won’t do a thing for you, just makes me feel better.” Knowing that trying to escape just added to her tormentor’s pleasure, Sunset stopped pulling and rested her hands on Celestia’s flanks.

The inside of Celestia’s ass was hot and steamy; Sunset could feel sticky, wet strands cling to her face after touching the walls of Celestia’s rectum. “There. Now your real punishment can begin.” Sunset heard a muffled gurgle come from deeper inside Celestia. A sudden blast of Celestia’s hot, stinky gas filled Sunset’s lungs as it rumbled past her. Celestia gently squatted down, forcing Sunset onto her knees. Sunset frantically worried about what was to come until she felt Celestia’s ass start to churn.

A chocolate brown mass of Celestia’s shit flowed towards Sunset’s face. She tried once again to free herself from Celestia’s ass, but to no avail. “Shh, shh, just let it happen, sweetie.” Sunset closed her eyes, and Celestia’s pasty shit pooled on her face like extra thick pancake batter. “You’d better start eating, Sunset. It’s not going anywhere else.” Shit continued to pile on Sunset’s face, not a drop of which went past her head. Knowing that she had no other option, she accepted her punishment and dutifully began eating Celestia’s shit.

Celestia’s waste was thick and fudgy. It coated Sunset’s mouth with a thick layer of muck as she took massive bites in order to keep a breathing hole open. It squished between her teeth as she chewed. Owing to the sheer amount of sugar Celestia ate in a day, her shit was surprisingly sweet. As sweet as shit can be, anyway.

Sunset took her hands off Celestia’s flanks and put them on Celestia’s belly, rubbing it’s swiftly deflating bloated figure. For every bit that Celestia’s stomach shrank, Sunset’s belly similarly grew. It felt like Celestia’s butt batter just kept coming, Sunset could feel her belly swelling with shit as she continued eating.

Eventually, Celestia’s mudslide came to a halt as her stomach returned to its natural size, leaving Sunset with a massively bloated belly full of Celestia’s shit. Celestia arose from her squat, bringing Sunset back onto her feet. Sunset felt the tingle of Celestia’s magic on her shoulders. Celestia relaxed her sphincter, and with a firm, gentle pull, Sunset popped out of her ass with a wet, sticky schlick.

Sunset’s face was absolutely covered with Celestia’s shit. Celestia’s horn glowed as she used her magic to instantly wipe off the thick, mucky veneer and embraced Sunset with her neck. “There, that wasn’t so bad, now was it?” Celestia cooed in Sunset’s ear, “If you would like, I request that you retire with me to my chambers.” Sunset followed her teacher to her room, gazing at the ponut she had just been enveloped by mere minutes before.

Celestia’s room was opulent, the entire space was painted with different shades of royal purple, by the hearth, there was Celestia’s bed, a low to the floor heart-shaped bed, draped in the finest purple and gold silks that Equestria could produce. Celestia’s horn glowed again and gently undressed Sunset, levitating her dirty clothes over to the hamper. “Lay with me, my student.” Celestia laid on her side, beckoning forth Sunset.

“Um… Celestia?”

“Yes, Sunset?”

“C-can I lay with my head by your posterior?”

Celestia let out a soft, regal chuckle, “Why, of course, my student.”

Sunset was starstruck by how soft Celestia’s bed was as she laid beside her. Putting her head right next to her teacher’s plump hole, she began rubbing Celestia’s equally soft belly. This time, as Sunset kissed and licked Celestia’s ponut, it was not out of punishment but out of desire.

Soon, Celestia’s breathing deepened and softened, indicating that she had fallen asleep. Sunset looked down at her stomach, so full of Celestia’s shit, she looked heavily pregnant. She realized that the feeding she had been given was not out of spite, but of love, as Celestia still cared for her. Sunset decided to join her in her slumber, both dreaming peacefully in their sensuous, peaceful embrace.

Chapter 2 (Introducing Luna)

Sunset woke as the sun still hadn’t arisen. Like how she and Celestia had fallen asleep, Sunset’s head rested against Celestia’s fat plot, dangerously close to her thick, juicy ponut. Celestia was still asleep.

Sunset looked down at herself. Her soft, pudgy stomach, previously almost bursting from Celestia’s shit, had deflated from looking 8 months pregnant to just about 2-3. Her body had obviously felt the effects of Celestia’s rich waste, having put on weight in all the places that mattered. Her breasts, thighs and butt had swelled nicely.

Sunset gently jiggled Celestia’s ass, thankful that it was all real and not just some dream. Seeing Celestia’s ponut again, she remembered her punishment from yesterday. She moved her hand to her neck, remembering the feeling of Celestia’s ass around her head and neck.

Sunset carefully, slowly pulled herself closer to Celestia’s ponut. She could pick up on her familiar scent as she brought her face closer and closer. Eventually, she was close enough to kiss Celestia’s ass and did just that.

Planting little pecks on Celestia’s anal entryway, Sunset continued her worship from yesterday. It almost felt like Celestia’s anal lips kissed Sunset back as she deepened her love. Kissing eventually turned to rimming and tonguing as Sunset moved her hands over to her teacher’s large, soft belly.

Sunset’s hands gently sank into the soft flesh underneath Celestia’s snow white coat. Sunset loved the gentle, motherly feeling that Celestia’s soft body emanated. It felt like she was hugging a jelly cloud as she melted into Celestia’s warmth.

That jelly cloud had some thunder, however. Celestia’s stomach vibrated as it gurgled and churned. Sunset’s breathing intensified. She whispered to herself, “Please, let me smell it. Let me have it.” Sunset put her nose to Celestia’s asshole and took a deep sniff.

Sunset gently pressed on Celestia’s soft, bubbly belly. She gently massaged the still-sleeping Celestia, trying to coax the gas out of her tummy. Sunset put her whole mouth and lightly sucked, trying not to awaken Celestia just yet.

With a little more coaxing, the rumbling in Celestia’s stomach became manifest and a long, hot wind of Celestia’s farts filled Sunset’s mouth. As Celestia ripped ass, Sunset graciously consumed gulp after gulp of her absolute window-opener of a morning fart. Sunset kept massaging more and more gas out of Celestia, swallowing it all as it blew out of her.

After the windstorm from Celestia’s gut died down, Sunset felt her start to rustle awake. “Mmm, good morning, my student.”

“Good morning, Celestia.”

“Did you sleep well?”

Sunset paused for a second, “Yeah, I did.”

Celestra rose to her hooves, “Splendid.” She looked over Sunset’s still nude form. “I’m not oblivious to the different reservations humans have about their nudity, so I will have my seamstress fashion you a new set of clothes while you accompany me. But first, I would like you with me when I raise the sun.”

Sunset and Celestia walked out to the East-facing balcony. “To anyone else, I might say to not stand behind me, but given yesterday’s events, I think you’re quite used to my ‘expulsions’ by now”

Sunset immediately knew what Celestia meant. Celestia flicked her tail to the side as Sunset again wrapped her lips around Celestia’s hole in anticipation. Celestia raised her wings high in the air with her tail. As the sky illuminated with the rising sun’s amber scarlet light, Celestia’s ass erupted into Sunset’s mouth again.

This fart was even longer than her sleep fart. Sunset tried her hardest to gulp as much of down as she could, but even for as voracious as she was, even she couldn’t manage to swallow all of Celestia’s gas. Eventually, the sun had been set on its path and Celestia lowered her wings, her fart mellowing in the same fashion.

Sunset gave a stifled cough, releasing some of the fart she had swallowed back into the air. “There,” Celestia said, “Now we can get on with our day; it will be a busy one, I warn you. But first, I’ll see you to my seamstress for your clothes.”

Of all the fashion styles Sunset could’ve chosen from, she decided to go with an overtly casual wardrobe, consisting of simply a white crop top with magenta leggings. The leggings clung to her, accentuating her curvier figure while her top highlighted her exposed pudgy belly. “Heh, the more that I look at it, the more I think I look like a teen mom.”

“Well Sunset, all I know is that I do admire your figure.” Celestia’s horned glowed and Sunset felt a tingle on her butt and belly as Celestia playfully jiggled her newly pudgier form. “But if we’re done here I do think we should be off, we have plenty of things to do today.”

By “plenty of things to do”, Celestia meant “plenty of things for her to do.” Most of Sunset’s day was spent following Celestia while she did her royal duties. No, most of what Sunset’s responsibilities boiled down to was servicing Celestia’s asshole, sometimes eating Celestia’s farts and keeping them quiet during any public proceedings.

Celestia had prepared for Sunset’s presence. In her throne was a beanbag chair, so that Sunset would be sitting comfortably at just the right level to serve her princess. As the court chatter increased as Celestia’s subjects clamored in, Celestia gently sat on Sunset with just enough weight to squish her ass into Sunset’s body.

The court didn’t contain much worth listening to. Sunset spent her time below Celestia servicing her like she should, licking and sucking and fingering Celestia’s ponut as she presided over the court. Every once in a while, Celestia would cut a nasty one into Sunset’s mouth, relying on her to muffle it as best she could. Followed by the court was lunch.As they ate, Celestia teased Sunset, “You know, my student, what I eat now is what you’ll be eating later.” Celestia giggled heartily as Sunset gave a surprised reaction to her public dirty joke.

After lunch there was a lot of paperwork, Celestia’s gut took a break from the farts, allowing for Sunset to just peacefully rim Celestia and play with her ponut, eliciting a symphony of soft moans from her. Eventually, the work day drew to a close and Celestia told Sunset her plans for them for the night.

“We’ll be meeting my sister for dinner at Chez Magnifique, though, you won’t be eating dessert there. Luna has been preparing your meal all day, something far better than any mortal chef could prepare. Though Luna's preparation is much more unaware than ours.” Sunset’s mouth watered at Celestia’s filthy insinuations.

Celestia and Sunset arrived early for their reservation. They were led to their booth and sat on the same side waiting for Luna. Sunset sat close to Celestia and was taken under her wing. Sunset melted in the warmth and comfort of her motherly princess. Sunset lent her head up against Celestia’s belly, listening to its soft burbling as if it were a lullaby.

“Aw,” Celestia cooed in Sunset’s ear, “did you have a busy day, sweetie?”

Sunset let out a childlike “mm-hmm” into Celestia’s belly.

Celestia chuckled, “Well, all that service must have tuckered you out. Did it taste good?

Sunset snuggled even more into Celly, “Mmm-yeah.”

Luna surprised them by walking up unannounced. She sat in the booth and was surprised to see Sunset, “Oh, hello. Sister, who is this?”

“Luna, this is Sunset, she was a student of mine.” Celestia proceeded to tell the long story of how Sunset had become stuck as a human, excluding the part about her “punishment.” Over the story, the group made their orders and ate all while Luna asked and Celestia told, with Sunset continuing to snuggle against her teacher while enjoying her meal. She also watched intently as Luna ate, fantasizing about the thick, fudgy waste that it would eventually become.

“That tale was quite fascinating. We had never heard of these ‘humans’, before.” After Celestia talked Luna into changing their dinner date to a sex date, she paid for all of their meals and they made their way back to Canterlot Castle. They walked up to Luna’s room.

Luna’s chambers were a striking piece of contrast. The otherwise opulent furnishings were marred by the empty chip bags and candy wrappers strewn about the place. In the better lighting of her room, Sunset could get a better view of Luna’s figure.

Luna was even somewhat pudgier than her sister, her plot was even rounder and her overall form seemed to carry a nice extra bit of fat. Seeing as how Luna was active when no other pony was, it made sense, no chefs to cook, so she ate junk food, and no open gyms, so she couldn’t exercise. Whereas Sunset’s mouth was perfectly level with Celestia’s plot hole, Luna was noticeably shorter than her sister; the dock of her tail was even with Sunset’s mouth.

“So, dearest sister, what did thou have in mind for our little ‘excursion’, on this evening??

“A little something off the beaten path.” Celestia’s horned glowed and Sunset felt the back of her head tingle. Already used to accommodating her with ease, Celestia’s ass readily accepted Sunset’s head.

Luna gasped as she saw Sunset’s head vanish up her sister. “Sister! What in the worlds hadst thou done? Why hadst thou inserted her up your posterior?!”

“Oh don’t worry Lulu, she just loves this.”

It was true, Sunset was on cloud 9 being inside of her teacher’s ass again. Her joy only increased when a whirlwind of Celestia’s gas around her like a hot, stinky breeze. Just as quickly as she was put in, Celestia pulled Sunset out again, proving to her sister that she was fine.

“And she just adores servicing the royal posteriors, don’t you Sunset?” Still dazed from the sudden insertion and removal, Sunset nodded yes.

“Well, thou still hasn’t explained what that display was.”

“It’s just a bit of simple insertion. She can still breathe, don’t worry. Believe me sister, it’s extraordinarily pleasurable for both parties.”

“Well, we don’t know about the… insertion, but she can certainly service our posterior.”

Celestia gently nudged Sunset and she quickly found herself kissing Luna’s deep blue ponut. Her thick anal lips were even sweeter than Celestia’s and they matched the taste of her insides as Sunset tongued Luna’s ass and slathered its rim.

Sunset kept servicing Luna, for many minutes more than she had spent in Celestia’s ass. Celestia smirked as she prepared for the treat she was going to give both of them. When Luna’s ponut and tunnel were sufficiently coated in Sunset’s saliva, Celestia started her plan.

Celestia's horn glowed. In a sneak attack, she pushed on Sunset’s head, slowly pushing it into Luna’s tight virgin asshole. Luna gasped and let out a sharp “Ah!” before her whine melted into a sensual “Ohhhhhhh,” as her plot jiggled.

Instead of being scared, Sunset felt a rush of euphoria as she felt Luna’s tight anal walls gently squeeeze against her. With one hand, she grabbed Luna’s supremely thick plot and playfully tugged her head against Luna’s sphincter. With the other, she yanked down her leggings and panties and started playing with her dripping pussy.

Celestia used her soft, motherly voice to calm down Luna, assuring her that Sunset was enjoying herself. “Shh, shh, it’s okay, you’re fine.”

Luna’s shock slowly abated as Celestia cooed in her ear, until she was finally able to nervously enjoy the situation. As Sunset played with Luna’s plot, Celestia rubbed Luna’s bloated belly and produced a drink for her. “Here, drink this.”

“What is it?”

“It’s a fast-acting laxative.” Seeing Luna’s eyes grow wide again, Celestia put on her motherly voice again, “Luna, trust me. If you think she’s having fun now, this will absolutely make her day.”

Luna hesitated, “Well… If thou think it to be right.” Luna quickly downed the drink. 15 tense seconds went by as Luna finally started to relax and enjoy the assplay. Her relaxation didn’t last very long however, as she felt the laxative quickly affect her.

Luna’s stomach violently gurgled and churned, working her past meals through her into her lower gut. Luna frantically pleaded with her sister, “No, no! We’ve changed our mind; we don’t want to do this anymore!”

Celestia rubbed her neck against her sister’s. “Shhhhh. It’s okay, Luna. Just let it all out.”

“No! We can’t.” The gurgling in Luna’s pudgy bloated stomach sounded like a drowning lion as she felt herself getting closer to the breaking point. Sunset felt Luna’s ass tighten around her as she clenched, trying to delay the inevitable.

“Please, dear sister! If for no other reason, to avoid making a terrible mess!”

“Hush, Luna. Even with me, not a single drop escaped when she was up there. I doubt your virgin ass is even loose enough to let your gas out.”

Luna whined as she realized she could no longer hold out against the demands of her own bowels. She instinctively squatted down so that Sunset was on her knees. Luna let out a loud, long groan “Huuugggh!” as she finally let go.

Sunset shut her eyes just before a flood of Luna’s hot, stinky brownie batter coated her face. The barest little toots slipped past the near-hermetic seal her ass formed around Sunset’s neck. Sunset quickly chugged Luna’s thick, sloppy muck, just slower than Luna produced it.

Sunset felt her stomach expand as she ate quart after quart of Luna’s shit. The thick batter coated Sunset’s mouth and throat in a film of muck as she swallowed and swallowed. Eventually, Luna’s flood stopped and Sunset promptly finished what was left.

“Um, sister?” Luna timidly asked, “Would thou, assist in removing miss Sunset from my rear?”

“Well of course, Luna.” Sunset felt Celestia’s magic again. “Alright, I need you to push on the count of 3, it’s like giving birth. Ready?” Luna nodded and Sunset braced herself. “1… 2… 3!” Sunset felt Celestia pull on her shoulders and Luna’s anal walls squeeze her out. With a fair resistance, Sunset eventually popped out of Luna’s tight ass with a loud, wet schlick.

All three of them panted as the thick muck that coated Sunset’s face filled the closed room with its stench. Celestia once again used her magic to wipe off Sunset’s face. “See, Luna? That wasn’t that bad.”

“Yes, hah hah, that certainly wasn’t the worst experience we’ve ever had.”

Sunset looked down at her stomach. With the fair amount of Celestia’s shit she still had from yesterday, combined with the fresh load of Luna’s, Sunset looked like she was carrying a set of twins almost at term.

After a quick clean up session in the bathroom, the girls all laid upon Luna’s bed. Celly and Luna faced the normal way, while Sunset, sandwiched between the princesses, laid the opposite way. As Sunset sucked on Celestia’s asshole, Celestia giggled to her sister, “You see, Luna? I told you she would love it. I think she’s practically addicted to our posteriors, possibly yours now even more than mine.”

Luna crossed her hoof over her sister’s. “Yes, it would seem to be that she does relish any opportunity to engage with our hindquarters,” Luna chuckled. Luna’s face turned quizzical and she asked her, “But We don’t understand, how can she so enjoy licking thy rear, even after such a display?”

Luna gasped as she felt Sunset switch her attention to her ass, gently licking and and sucking the thick lips of her anus. In a group cuddle with a ponut on either side of her, Sunset quickly drifted off to sleep while sucking Luna’s ponut, softly embracing her two pudgy princesses.
