        “How much further is it?” Twilight Sparkle asked as she followed Princess Celestia down the hall, her voice filled with a sense of urgency. 
        “Twilight, you’ve walked these halls for most of your childhood.” The sun princess replied rather abruptly. “You should know just as well as I do how far we are.”
        “I know, I know, I’m just… I’m not sure how much longer I can wait.” The base of Twilight’s violet tail twitched as she struggled to keep it down while she followed her superior. 
        “I understand, I am just as desperate as you are.” Celestia acknowledged. Each step she took was frantic, but precise and calculated, her buttocks clenched tightly together. A bit of sweat began to form at the back of her neck as she rounded the corner, the smaller princess tailing close behind. Celestia stopped in her tracks as she felt a bit of solid mass poking at her anus, and clenched her muscles together as hard as she could. As she fought to regain control, she swore that she would never let herself gorge on such delicacies as she did at the feast in Vanhoover earlier that day… even though she knew she most likely would. After all, it was so rare for she and Twilight to feast on Cajun fried grass-kebob, barbecue hayburgers,  and honey roasted celery sticks. Celestia had made sure that both she and her prodigy had eaten their fill of such riches; perhaps even a bit more than they could handle. 
        By the end of the feast, Celestia and Twilight were so full that they almost needed to be carried out of the dining hall to make their appearance at the Needle Point Tower in the city. By the end of her speech, Celestia could feel her belly making some very calling noises and movements as it processed her lunch. Looking at Twilight and seeing a rather concerned look on her face, she urged her guards to prepare their chariot back home to Canterlot. During their flight home, Celestia felt a bit of a gurgle in her stomach and a light pressure at the center of her rear. Looking at Twilight out the corner of her eye, she confirmed that the younger alicorn wasn’t looking at her, and leaned a big slightly forward. Pushing very gently, Celestia let a gust of foul wind blast from her cheeks with a vicious prrrrrt. The look of wide-eyed shock on her face confirmed that it was much louder than she had intended it to be, enough to make Twilight turn her head to Celestia and shoot her a look of disgust as she held her nose in front of her hooves.
        Celestia’s face turned a very apparent shade of red as she apologized several times. Her nose still wrinkled, Twilight put her hoof down in front of her lap, and her eyes darted from side to side. Leaning to her left and letting Celestia get an eyeful of her purple buttocks, her tight anus flexed and let out a soft poot of her own. Twilight grinned and stuck her tongue out as she fanned a hoof under her behind. Celestia giggled, and repositioned herself so that her head leaned on the side of her chariot, and her rump faced towards Twilight. Celestia wiggled her behind in a seductive manner, before her ethereal tail raised and another purr of gas escaped her cheeks. The two alicorns roared in laughter, Twilight accidentally farting again as she laughed, which only added to their amusement. All the while, the guards pulling their chariot remained dutifully unaware of the grotesque game their princesses were engaging in, their eyes fixed forward and the current pushing any possible stench in the opposite direction of their flight. 
        Celestia flexed her back to let out another puff, but she quickly cut herself off after hearing a high pitched squeak, followed by a more intense pressure on her anus. Celestia quickly lowered her tail and sat back down, pushing her rump into her seat to pull the solid excrement back up into her rectum. After regaining control, Celestia crossed her hindlegs and offered a nervous smile at Twilight. The younger princess seemed to regret their game of breaking wind as well, while she held her hoof in her mouth and looked off into the distance, as if she were praying to see Canterlot castle soon.
        Celestia knew in her mind that it would have been so much more practical to use a restroom in Vanhoover before their flight, to avoid worrying about the speed of their chariot towards home. However, that would have put her and Twilight at risk of giving some tabloid journalists a field day. She could see the headlines now: Old and New Princesses Casually Drop Bombs in Vanhoover Stalls: Eyebrows in Critical State of Never Growing Back Properly. Besides, she knew that no public facility could ever match the grace of her own personal throne of porcelain. It was worth the suffering for her to reach her own private pooping sanctuary… if she could make it in time. She could just envision herself, her buttocks over her toilet, plopping them down and breathing a sigh of relief, and letting her whole body relax, letting nature take its course; her desperation would be all gone in one movement…
        “Princess…?” Twilight’s voice permeated Celestia’s thoughts. “Princess!”
        “Huh!?” Celestia snapped back to reality, now aware that she had been standing in one spot with her tail slowly rising up.
        “You’ve got to move princess, you stay in one spot for too long and you’ll never make it. Fight it!” Twilight urged, her own hindlegs crossed in urgency. “We’re almost there. Your room is right around the corner, isn’t it?”
        “Y-yes…” Celestia replied, her voice a bit weak. Taking a deep breath, she forced the muscles in her anus to contract and sucked back in, letting her sparkling tail cover herself properly. She willed herself to move forward with her companion, and used as much magic as she could spare to open the door and let herself and Twilight in. Celestia quickly tossed away her tiara and necklace, and kicked off each horseshoe while Twilight undressed herself as well. Magically opening the door that led to her bath chambers, she and Twilight dashed to the door that divided the rest of the room from the object they sought, and threw it open.
        There it was: a large sparkling seat of porcelain with shining golden laces on the sides of the bowl, and a roll of soft material on the back of the basin. The two alicorns gazed upon it in all its shining glory and smiled in relief, before turning to each other with a polite smile on their face. “You first.” They both said simultaneously.
        “Princess, that’s sweet of you.” Twilight replied. “But you need it a lot more than I do.”
        “Twilight you’re my guest.” Celestia retorted. “I want you to use it first.”
        “I didn’t eat nearly as much as you did, go ahead.”
        “But you’re smaller than me; your body can’t hold it in as long.”
        “But that means you’d make a bigger mess if you didn’t make it!”
        “Twilight, I’m touched by your concern, but I promise you I’m perfectly capable of-!”
        “Princess, you’re crowning.” Twilight said, her eyes fixed on Celestia’s behind. 
        The large alicorn was unable to see it for herself, but there was in fact a small brown nugget poking its way out of the soft flesh of her white bottom. It was too far out even for her to pull it back in, lest she risk cutting it off and it falling down on the floor. 
        “Shoot shoot shoot shoot!” Celestia muttered as she tip-hoofed over to the bowl, careful not to let the muscles of her behind twitch even slightly. She looked at the large bowl, and then back at Twilight. “Come sit with me.” She said.
        “W-what!?” Twilight asked as the alicorn in front of her turned about and scoot back against the basin.
        “There’s just enough room for you to sit in front of me. Come on, hurry before you let it torture you any further.” Twilight’s eyes danced nervously, but she forced herself to step forward and let Celestia pull her up and turn her about so she sat in her lap with her back resting against Celestia’s soft white chest. Celestia’s hoof ran across Twilight’s back as the little alicorn breathed nervously. “Ssh, you’re okay, just relax.” She said, as she let go of the control she had been fighting to keep for what seemed like ages. The sound of a few nuggets dropping from her behind and splashing into the water rang out, along with the crackle of a rather fat brown log slipping out of her hole and dipping into water. “Ahhhh…” Celestia moaned out loud as she felt the solid waste she had been holding back leave her. The feeling of relief swept over her, and she let her glorious wings spread out fully.
        “Mmm… mmphh…” Twilight grunted a bit as Celestia continued to rub her back, and she let out a low puuuuut that echoed in the dome of the bowl she sat on, and increased in pitch until a hiss escaped her hole. What followed was a thick brown mass of waste from her tight anus. “Ohhh!” Twilight cooed as the log pushed out of her body, until it snapped off and splashed below her, her hole shrinking closed again before another could escape. 
        “Feels good, doesn’t it?” Celestia grunted in a whisper, her own thick snake-like mass beginning to curl up once in the water, before dropping off. She began to rub Twilight’s tummy softly, eliciting a soft hum from the alicorn in her lap.
        “Hmm, yes…” she moaned with her eyes closed. A soft trickling sound filled the porcelain seat as a stream of Twilight’s urine splashed against the inner front of the bowl and poured down to join the mess underneath them. 
Celestia smirked and rubbed her hoof just underneath Twilight’s waist, as she gave another push to her own rectum. The pressure caused her to release her own golden stream, making a light pouring sound as it splashed against the surface of the pool. Another turd emerged from Celestia’s anus and crept out to the water below. Twilight’s moaning increased as her wings spanned out, and she began to lean back further into Celestia’s chest, her stream of urine beginning to rise and splash a bit onto the top of the seat. Celestia quickly reached out and held Twilight still before it could spray onto the floor, her sudden movement making her anus close well before her log was finished, and snapping it clean in half so it splashed below her with a loud plop.
“Careful dear, don’t go too far.” She said calmly. Twilight quickly leaned forward and held herself upright with her forelegs, careful to keep away from the dribble she had released on the seat. Celestia resumed pushing her waste out and leaned forward to tickle Twilight’s privates, getting her to relax once again. Twilight sighed as her stream resumed. Celestia rubbed her inner thigh as she tinkled, and the remainder of her own excrement dropped off into the water as her stream finished off with only a few drips. Once Twilight’s stream had subsided, Celestia replaced her hoof against her wet mare lips and rubbed her firmly, causing the little alicorn to moan profusely, a few grunts escaping her as she pushed her anus muscles into opening again. 
“Ahhh… ah…. Nnnngh…” Twilight moaned, and a small log emerged from her bottom, stretching her out only a moment before it dropped completely into the water. Celestia quickly pumped her hoof into Twilight’s soaked lips and kept her chin on top of her purple mane. “Ah, ah, ah, ah, ahhhhh!” Twilight arched her back as she shot another stream of urine and her own filmy liquid into the toilet. She sighed contently as her body relaxed. She leaned forward and allowed herself another soft pass of gas before she shook her lower body. 
“All done?” The sun princess asked, to which Twilight looked back at her and nodded happily. “Good. I’m almost there myself.” Celestia took a deep breath and strained, and Twilight took hold of her hoof into her own. Gripping onto her student, Celestia gave herself another push and forced out another fat but short bit of waste into the toilet, causing her to sigh out in relief. Giving another gentle push and hearing nothing but a wet fart, Celestia decided that she was finished as well. She kissed the top of Twilight’s head before the little alicorn placed her front hooves on the floor and stood herself up off of the toilet. With her tail raised up, Celestia could see a tiny brown smudge on the side of the surface of her anus. Using her magic, Celestia pulled a bit of the soft material on top of the basin and snipped it off when she had a bountiful amount. 
“What’s that exactly?” Twilight asked curiously.
“Silk.” Celestia replied cordially.
“Are you serious? You wipe yourself with silk?”
“Have you ever tried it before?”
“No, I haven’t. But I wouldn’t feel the need to- hah!” Twilight gasped as Celestia pushed the soft material up between Twilight’s cheeks and rubbed against her dirty anus. “Oh, oh my gosh, that feels good!”
“Told you!” Celestia said curtly, rotating the material in little circles around the rim of Twilight’s hole. 
“Mm… mm, okay! I think I’m clean, princess!” Twilight cried out urgently. Celestia pulled the piece of silk back, folded it over and gave her one last wipe before she pulled away. Examining her purple hole, it was indeed spotless; the same could not be said however for the smooth sheet being levitated by her magic. Celestia dropped the used sheet between her legs into the bowl, and picked herself up off of the seat. Turning herself around, she pointed her large posterior at Twilight and moved her wafting tail to the side. “Now, do me.” 
Twilight wrinkled her nose and chuckled. “I would love to, but… you’re kind of a mess back here.” She explained, taking in the sight of Celestia’s large rump, the center of her cheeks a spattered brown mess, the damage of her snapping one of her turds in half very apparent. 
“Oh, very funny.” Celestia remarked as Twilight’s magic pulled off almost triple of the amount of silk she had used on Twilight. The large cloth pressed up just above Celestia’s wet mare lips and dragged upwards, pushing the brown filth off of her skin and onto the material bit by bit.
“Mm…” Celestia hummed as she felt the silk move across her bottom. Once Twilight had reached just under the base of her tail, she folded the cloth over and started again at the bottom to wipe upwards. “Ohhh!” Twilight took care to wipe a bit from her tail downwards to keep any mess from clinging there. Finding what was left of a clean side on the material, Twilight inserted the cloth into Celestia’s anus and wiped her thoroughly, pulling in and out and circling her thoroughly. “Ahhh, ahhh, ohhhh!”
“There we go, all clean.” Twilight decreed, dropping the dirty cloth into the bowl. She gave Celestia a pat on her right cheek. “Looking good, big sexy.” She said, as her magic surrounded the handle on the basin.
“Twilight wait, don’t flush!”
“You’re… you’re kidding, right?”
“No, I’m serious.” Celestia looked into the bowl, and took note of what was there: A thick log a little over half a foot, and a small short piece no bigger than a rock lay in the front of the bowl. The back however held one solid log clearly over a foot and a half all curled up into the bottom, topped with two severed halves of a thick foot long, and to the side, a fat turd almost half a foot long. There was easily at least four feet of pony manure in this very bowl, and Celestia couldn’t even see the drain underneath it all. “I think it would be very unwise for me to flush at this point.”
“That bad, huh? Hopefully you have a good plumber in the castle.”
“He’s not going to be happy about this, I fear. I might actually have to sleep with him in exchange.”
Twilight chuckled. “You think he’s going to want to sleep with you after seeing that?”
Celestia wondered a moment. “Good point. I might have to pay him up front.”
Twilight snorted in laughter, then immediately held her nose. “Let’s get out of here, princess.” She said. Celestia’s nose twitched as the pungent odor of their droppings and gas finally occurred to her. “I won’t even risk lighting a flame spell, or we might end up setting the room on fire.”
Stepping away from the toilet, and closing the door before the aroma had any time to escape, Celestia pranced quickly towards one end of the wall and turned the knobs to activate the showerhead. Putting her hooves out, she felt the warm stream wash over her hooves. Closing her eyes, she stepped underneath to let the water soak and weigh down her flowing mane and tail. She felt a small body brush up against her, and opened her eyes to see Twilight against her side, her purple mane slicked back against her neck, looking up at her with an appreciative smile.
“I love you…” Celestia stated, lowering her head down and hugging Twilight. “… My little stinker.”
Twilight giggled and nuzzled her long neck. “You too, you big ball of gas.”
The two alicorns held each other’s embrace underneath the warm stream of water pouring over them. Celestia suddenly gasped.
“Oh! The sun, ball of gas, I get it. Very clever.”
