Where the Sun Doesn't Set [Scat]

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.
