-------------------
	It was Christmas Day, a celebration usually shared with family, joyous and cheerful, with presents being traded and food being shared… however, Tulip and Cynder had decided to celebrate it in a different way. 

	Both of them were sitting on Cynder’s couch, in her living room, with Alkaline the wolf sitting between them, looking nervous. “What’s wrong, darling~?” Tulip the Lopunny asked with a smirk. She was currently covering her privates with a white diaper - an odd sight to begin with, but there was more to it than that. The diaper had on it a blue ring, built right into the fabric; it acted as a one-way portal, located right beneath her ass, which was connected to another portal in a muzzle. Cynder the kitsune, coated in purple and white fur, was putting on the same type of portal diaper, a somewhat devious and very excited look on her face. “Aren’t you excited for your Christmas present~?”

	“I-I mean, I am,” Alky the wolf said, blushing; he was entirely in the nude, his own fur a similar color scheme to Cynder. “But, um, you d-didn’t tell me I’d be feeding from both of you at once… o-or that I wasn’t going to be able to take the muzzle off…”

	“Don’t worry, Alky - you’re going to love it~” Cynder spoke, holding up the muzzle. “Open up~ My stomach is already rumbling~”

	Alky gulped nervously, and, against his better judgment, opened his mouth. The muzzle was black, with an orange portal on the inside, where Alky’s mouth would go; it jutted out just a little bit so it would stick into his mouth. His lips would fit right around it. He’d been told that Tulip and Cynder were both wanting to use him as their toilet during their Christmas celebration; he’d expected to be kneeling on the floor and being used occasionally, with little loads here and there, but instead, the girls were treating him as the main attraction. Still, he didn’t resist. He was scared, but also excited… as his rock-hard shaft made clear. 

	Cynder put the muzzle on; the portal was shoved into his mouth, deep enough that he couldn’t get it out. Instead of tying the straps into place, she clicked two metal pieces together: it was a lock that would make sure that muzzle wasn’t coming off until they took the key and removed it themselves. “There we go~” She chuckled, grabbing a bottle of liquid laxative. “Ready, Tulip~?”

	“Of course~” The Lopunny grabbed a similar bottle; the two clinked them together, and both immediately began to down the bottles, drinking a full liter of laxatives in one chug. Immediately, their bellies both began to rumble loudly, gurgling and growling, the sound of the medication clearly working; each of the girls held their stomachs, leaning back, Cynder groaning just slightly from the feeling of her bowels moving so much. There was only just the slightest bit of sickliness, of aching, in their stomachs… but that aching was soon resolved. 

	“Here it comes~” Cynder announced; Alky shivered in anticipation. 

	“Ready, darling~?” Tulip chuckled, knowing Alky couldn’t possibly prepare himself for this. “Before we forget…” the bunny grabbed a butt plug attached to a strap, and put it around Alky’s waist, shoving the plug deep into his hole. She then clicked the strap together, and it, too, was locked, guaranteeing that the poor toilet slave wasn’t going to be able to relieve himself of any of the pressure that was soon to hit. 

	“I can’t hold it any longer~ It’s coming!” Cynder proclaimed; Alky let out a little whimper… but that whimper was almost immediately interrupted and muffled by a stream of shit going right into his mouth.

	Alky moaned from the mix of pleasure and discomfort he was suddenly subjected to. The shit was a horrible mix between soft and hard; it came out as a consistent flow, but it wasn’t like a liquid or anything, rather, it was just going so fast that every log seemed to mush together to create what looked like a raging waterfall of shit. Cynder’s shit wasn’t like real shit - it was a mix between sweet and bitter, with light sourness and acidity mixed in, like a fruity vodka cocktail. The color soon showed itself in the diaper - not every bit of the shit could go right through the portal due to how fast it was coming out, so the diaper quickly filled, taking on the cyan hue of the shit as it bulged in all directions. Though, this was short-lived, as, once the diaper was full, it just caused all the new shit to be pushed right into the portal even faster, as it now had nowhere else to go. 

	Alky’s face went entirely red; he clutched his arms and gagged and shook as shit roared down his neck. The taste, although much more pleasant than normal shit, was overwhelming in its quantity and potency. He swallowed it down at first, but soon, it was coming so fast, that he just had to let it all stream right down his throat at a tremendous speed. The texture made it a bit easier, being very goopy and mushy; it was like applesauce almost, but a bit more thick.

	“Wow, you were really holding a lot in~” The bunny said, chuckling. She put a paw to Alky’s throat and felt it bulging and rippling as all the shit went down, the sounds of his feeble attempts to properly swallow reminding the bunny of a sewer pipe on the verge of bursting open. “Poor Alky~ Unfortunately for you, it’s about to get a lot worse. You know my shit isn’t nearly as tasty as Cynder’s~”

	Alky looked at Tulip with concern; already, this was enough shit that he could feel his body getting filled to the brink, his internals becoming backed up like a clogged toilet. He wasn’t sure how much he could realistically handle…

	…but it seemed that today would be the day where he discovered his limit, because Cynder and Tulip were going to be pushing right past it. 

	“Lay down on the ground for me~” Tulip commanded; Alky nodded and quickly did as told, like an obedient dog. The bunny stood and squatted over his face, then sat down on it, letting the white diaper crinkle against him, covering his eyes and blocking his vision in the process. He could feel the warmth of her bunny ass through the material. She reached down and held his shaft in one paw, lightly rubbing the side, making him quiver from the sudden, unexpected sensation of her touch. “No cumming, not without permission, ok~? Otherwise, I’ll make sure that mask and these diapers stay on until the end of December~”

	“Mmmm…” Alky responded in affirmation; it was going to be difficult… but he really didn’t think he could handle being a toilet slave at this level for that long, and he knew Tulip wasn’t joking, so he’d have to try his best. 

	“Here it comes~” A loud sound that sounded somewhere between a fart and a blort echoed out; the bunny’s diaper suddenly turned to a sickening shade of mahogany brown, filling with her shit in mere seconds so that it bulged from all sides… and of course, it was soon going straight through the portal as well. 

	The shit itself, even through the diaper, was remarkably potent in smell; being that close to it, Alky was forced to sniff it in, the smell making him feel sick and lightheaded. At the same time, it was warm and steamy, in a way that was actually comfortable - it was like his head was being pressed against a heated blanket. It lulled him into a state of relaxation… which was soon ruined by the force of her shit going into his mouth.

	While Cynder’s stream was far more mushy and goopy, Tulip’s was hard and solid. She wasn’t shitting out anything that resembled a flow of liquid, rather, she was pumping out hard, solid, long, and girthy logs, all of which were funneling right into Alky’s mouth and making their way down his throat without losing their form. Tears formed in his eyes from the uncomfortable and overstimulating sensation, his throat burning; every bit of shit that entered his system from both of the doms made his body so sick and pained, his brain rejecting the toxic waste that he clearly should not have been consuming, but he was powerless to stop it. All he could do was sit and let it flow inside of him. 

	“Mmmm… that feels so good~” Tulip said, moaning in pleasure.

	“Agreed~” Cynder responded. The two of them both were experiencing the wonderful sensation of their guts being emptied out, like draining water from a pool, with the drain being Alky’s mouth. It made them both feel relieved and peaceful; it was like their bodies were being freed from a heavy burden, literally made lighter from the removal of pounds and pounds of shit.

	Cynder soon squatted down on top of Alky, letting her shit-filled diaper rub lightly against his cock, the warmth from it making his legs quiver as he held back his orgasm still; she leaned towards Tulip, lightly held the bunny’s chin, and gave her a little kiss on the lips, getting intimate as they both continued to shit. Cynder was especially experiencing a wonderful sensation right then - her own dick, being buried in her warm, full diaper, was constantly being stimulated as the diaper filled, making her feel horny and lustful. The look in her eyes was sultry; there was clear desire hidden behind them. 

	Wordlessly, Tulip wrapped a paw around Cynder’s face and pulled her close, immediately pushing their lips together and making out with her, as they both sat on top of their toilet slave. The deep kiss was accompanied by the sound of both of them moaning and making sounds of pleasure, while at the same time occasionally grunting and groaning when they had to really focus to push out a particularly big log or burst of shit. Below them, Alky continued to be fed, his cheeks constantly bulging out from how full he was; if the tube wasn’t going into his mouth, he’d have definitely failed to continue taking all this shit in, but with his current position, he didn’t have any other choice but to let it through. 

	His body was starting to get very full, full to the point that his stomach was beginning to inflate, slowly ballooning up, between the two girls, as they continued their passionate kiss. The stomach expanded upwards and outwards, quickly getting to the point where the weight and mass made it so that, even if Alky wasn’t being sat on by the two doms, he wouldn’t have been able to stand or move an inch. 

	The girls eventually stopped and stood, looking down at what was happening; they watched as Alky’s eyes became hazy and glazed over, his belly just continuing to full, his neck stretching out considerably, to unnatural levels, to accompany the flow. They were still shitting, even now - their bodies had held in so much, it would take a very long time to get it all out. The bunny placed a foot on the belly and, with a smirk, she stepped on it a little bit, pushing in the pudge; it was bouncy and squishy, like a big plush ball. “Wow, poor toilet slave~ It’s going to take a very long time for you to recover from this~”

	“Hold on - I want to make it even better~” Cynder said, chuckling deviously as she walked to her kitchen. 

	Tulip laughed as well; she had an idea of what was coming. As Cynder reached the refrigerator, Tulip sat on Alky’s dick and began to rub her dirty, full, warm, shitty diaper against it, stimulating it, making the hard shaft throb and quiver in pleasure; Alky tried his best to hold back an orgasm, but it was getting harder with every passing moment. Tulip’s shit had such a wonderful sensation to it, even inside of her diaper; it was so warm, and the bulge and bumps were so pleasant. The diaper even felt a bit wet and damp, though nothing was leaking out. 

	And suddenly… Alky’s eyes went wide as he was treated to a waterfall of shit suddenly massively flowing into his system. Cynder was chugging yet another bottle of an extra strong laxative; its effects were immediate, causing so much more of her shit to begin rushing out at double the original pace and size. It overwhelmed the poor toilet slave so much that his mind stopped working correctly, being used so much to attempt to understand and perceive what was happening to him that it short-circuited. He didn’t fall unconscious; rather, he became almost catatonic, unresponsive, unable to speak or think anything, just feeling what was happening to his body.

	This made him completely unable to control his pleasure and his actions; it was a recipe for disaster, considering how Tulip was rubbing against his shaft, and how high the consequences of him orgasming were. But to make it even worse, Cynder joined in. She sat on Alky’s stomach and pushed her own diaper against the dick, making it so her and Tulip were now rubbing against it as it stood straight up between them, fully feeling it up and down with their warm, messy, dirty diapers, squishing it between them, treating it like a toy. 

	And in mere moments, it became too much for Alky. He let out a moan, his legs shaking, as his seed spurted into the air, going all over the diapers and the ground around him, eventually leaving the shaft just a little more flaccid and weak than before. The two girls chuckled like school bullies; they quickly embraced and made out again, this time falling against Alky’s body. Soon, they both orgasmed as well, their whole forms shaking in pleasure as they filled their diapers with their femcum to go along with the shit, which eventually made its way into Alky’s mouth as well. 

	By the end of their loads, Alky had ballooned up so much, he looked like a beanbag. His stomach functioned perfectly as a seat, or even a bed, and Cynder were having plenty of fun using it. Unfortunately for him, though, he wasn’t going to have a chance to recover from this any time soon. “Since you came…” the Lopunny began, “...as I said, you’ll have to keep that muzzle on until the end of December~ That means six more days for you~” She chuckled sinisterly. 

	Cynder spoke, “Of course, we’ll probably have to take these diapers off to clean up eventually… but don’t worry - we have plenty more, all of which are connected to that muzzle~ Maybe we’ll have some friends over for a New Year’s celebration~” The two both laughed at the poor toilet’s misfortune; Alky had regained his senses enough to understand what they were saying, and he whimpered and whined, knowing he was going to be stuck as a toilet for a long time.

	But really… he wasn’t actually that upset about it. In fact, he couldn’t help but let his tail wag in excitement. This was practically a dream come true for him - it wasn’t exactly how he’d imagined it, but being a toilet, used to this extent… it was all he could ever hope for… even if it was a lot more than he’d expected. 

	“Oh, I think I feel a second wave coming on~” Cynder said, grabbing another bottle of laxatives from the refrigerator. “Do you want to join me, Tulip~?”

	“Of course - I’ve always got more~” The bunny smirked, taking a bottle herself; the two soon downed it. 

	Alky was going to have a very long December ahead of him.
