Trixie's Less-Than Clean Magic Show

Ten Minutes Later

“Mmmmphhhhhh… Oh goddess, no…”

Starlight wasn’t sure how much longer she could try hiding behind the curtain, but it wasn’t stagefright keeping her in place. Instead, she was struggling not to buckle over while leaning against one of the stage’s support-beams. Her head was hung low and had her hand clasped over her stomach. She groaned harshly through her teeth, making sure to inhale as slowly as she could to help alleviate her intestinal pressure.

“Damn that breakfast,” she muttered under her breath, silently cursing herself for going so overzealous at the buffet earlier. She had assumed that it wouldn’t cause much of an issue, but she was gravely proven wrong. Even before the first show ended, it became clear that her wetting was merely a warning for what was to come. She tried her best to pucker herself in tightly, but she wasn’t sure how well that could last during her next performance act.

“Starlight, come on!” Sunburst poked his head through the curtains for a second to catch her attention, but he disappeared just as suddenly to return to the main stage. But even in that brief second, she was able to hear a strained grimace from the stallion that made her worry. She didn’t have enough time to talk with him while they rearranged the props for Trixie’s act between shows; not to mention, their squishy diapers proved to be a hell of a distraction when the padding started to become cold and clammy between their legs. By the time the two had a moment to breathe and recompose themselves before their next show, they were each dealing with a lot on their own accord

“Mmmmffff…” Sunburst waddled back to the front of the stage, where Trixie was patiently waiting with a coyer smirk. All of the younger attendees have already left to return to classes, so now the audience was composed of mostly the older students, as well as some of the school staff and neighborhood ponies. The fact that there weren’t any kids was only a little relieving, since they were now replaced with ponies who Sunburst and Starlight knew personally. The stallion’s heart was already racing to match his blushing face, and his muzzle wasn’t the only part of his body he was desperately trying to clench up. Fortunately, his forced smile wasn’t too distracting to the crowd when it matched the equally dire expression frozen across Starlight’s face.

She was whimpering a little when she returned to the stage, and stood at Trixie’s other side in her ridiculous getup. After both of them filled the front of their diapers with so much pee, the crotches were most notably obvious to anyone who knows what it’d look like. She and Sunburst could only hope that there weren’t too many parents in the audience, or that there wasn’t too much attention brought below their waists. Luckily, their capes were adorning them well enough to cover most of the bulging from the sides.

“Come one! Come all! To the Great, and Powerfuuuulllll Trixie’s fabulous magic show!!~”

Trixie was keeping right on schedule, and got the second magic act started without any delays. Neither of her friends mentioned anything to her about what happened, so they were just playing along and hoping they didn’t squish too audibly on stage. Trixie certainty didn’t indicate she was aware of anything, as her boisterous attitude kept both her assistants on their toes for her parlor tricks. Their movements were a bit more stiff and forced compared to the first show, but neither of them made any big mistakes either.

Sunburst did nearly fumble Trixie’s knot-untying act, since he was clutching to his end of the rope for a few seconds longer than planned. Of course, given how red his face was getting with a harsh exhale, Starlight could tell that he was likely clutching something else equally as tightly. She gulped worriedly, not wanting to think that she and Sunburst actually got food-poisoning from that breakfast place. But alas, with each minute spent in agonizing torment as her bowels became harder to ignore, she eventually became grateful that Trixie avoided that buffet at least.

By the time Starlight was left on the stage to help with a couple card-tricks, she was trembling hard enough for her thighs to twitch while bunched together. Her face went pale for a brief moment after she readjusted her weight as subtly as she could, which made her realize that she was already feeling the urge to pee again. She had no idea how it was even possible, but she had to hope that the strain in her bladder was just a bad after-effect of such a mortifying experience.

Unfortunately, after she breathed out in a low and shaky hiss, she wasn’t sure how much longer she could keep standing in front of everypony without kneeling over. Her smile was stretched as thin as it could across her muzzle, to the point where her lips were nearly invisible against her paled coat. But after her months of experience working with the magician, she knew how to present herself well enough so nopony could catch on to her internal struggles. “... nnnffffffff…”

“Aaaahhh!~” Sunburst was lucky enough to hide backstage for a moment, although he couldn’t exactly walk out in his state. Not only did he have to cling to one of Trixie’s stage support-beams with both hands to keep himself on his feet, but his knees were bending in to force him into an undignified squat. He was groaning hard through his teeth, and desperately hiding his distressed voice as best as he could. Eventually, he had to let go of the beam with one of his hands so it could reach down and grab his padded rump tightly. For several seconds, he sucked in a deep breath and struggled to hold back the breach threatening to ruin his upcoming performance. “Gnnnghhh! Ughhh…”

Sunburst eventually pulled back strongly enough to keep the threat at bay, and he sighed in relief with his head hung low. Still though, he had to shake his head and make a mental note to never go back to that restaurant again; or at least, he shouldn’t have gotten thirds from that damn buffet…

“Oooooffff…” In a last-minute attempt to settle his insides, he lit up his horn so a tight aura could be wrapped around his waist. It was white enough to mostly be transparent, so he could only hope it wouldn’t be too visible back on stage. He made sure to take a small box of props with him, just to have an excuse for being backstage when he went through the curtains discreetly. Of course, as soon as he scurried back out to resume things alongside his friends, he almost gasped in offense when he noticed a similar aura of a near-invisible blue aura around Starlight’s hips.

“TA-DAAAA!!~” Trixie had just finished her big rope-untying act, with Sunburst swooping in just in time to hold the limp end of the line with a forced smile. Both he and Starlight were straining hard, knowing that their magical interference was a very temporary solution. But when they remained frozen in place, both of their stomachs were grumbling loud enough for a few attendees in the front rows to tilt their heads puzzledly.

“Now, for my next act…” Trixie hummed with a more sinister-looking grin, and paused long enough to see how both her assistants were looking. Since neither of them seemed to be too exhausted at the halfway point of their work, she decided to light up her horn and catch both of them by surprise. “I’m going to need both of my volunteers to get themselves strapped in~”

“W-What?!”
“WHAT?!”

Despite the unicorns’ panicked reactions, their voices were cut off fairly quickly by the excited applause from the crowds. Both of them gulped with their blushes growing heavier, and their horns illuminating brighter to literally hold onto their butts. They tried to maintain their smiles as best as they could, but a good portion of the audience could see a bit of distress when they turned around. Sunburst and Starlight struggled not to groan, but their waddling was much more obvious when their legs were becoming stiffer with a wider gait.

“Come on, assistants…” Trixie may have not been able to see the distress on their friends’ faces, but she was quick to get both of them in their bondage. It may have been a little earlier in the show than planned, but the magician was known to improvise when the mood was right. She helped lower Starlight back in the coffin for her upcoming magic act again, even when the mare tried to give a frantic shake of her head and mouthed “No,” several times. She lowered the lid on top, right when Starlight desperately tried to whisper something:

“Trixie, wait! WAIT! I really need to go--”

Her voice was cut off right before the important part could be heard by Trixie. After latching the top shut, all she heard was a strong whimper from inside the box. She then looked back at Sunburst, who was blushing profusely with a clenched muzzle when he made a nervous gulp. He looked like he wanted to say something, but he was left silent when he saw how quickly Trixie shut down Starlight’s protests. He wasn’t even able to say anything, as Trixie used her magic to gently grab both of his wrists.

“Alright, just a moment…” Trixie helped get that cloak off Sunburst’s shoulders, and hoisted him onto the circular board for his second run with the spinner. The first time they performed the act, the stallion was thankfully able to remain still without much issue; although, that was mostly because he had just peed himself, so he was alright with being spun around a few times while Trixie threw water balloons at him. But this time around, with his stomach starting to bulge out from how badly the maltitol was stirring the contents inside, he had to grit his teeth when he was forcefully strapped to the wall.

“Mmmphh!~” Sunburst shivered when he was pulled back by all four limbs, and braced tightly to the wooden circle by his back. His diaper was pressed up just as snug due to the pressure, leaving no reprieve for the soggy padding bunched between his legs. With the cape gone, he could only imagine how obviously his diaper was bulging out white the lycra was hugging every curve. He tried not to look out at the audience, but he ended up cringing when he noticed a few ponies narrowing their eyes or staring at him quite peculiarly. “... nnnghhhh…”

“Oh no…” Inside the box, Starlight Glimmer had to fidget quite a bit to pull both legs up from the bottom section. Since her head was sticking out for everyone to see, she had to keep her expression as neutral and casual as possible while maneuvering in the cramped space. She groaned hard when she managed to get both of her knees up to her stomach, but that uncomfortable position caused her to accidentally press down on her waist. Her eyes shot wide-open, and her horn tried to light up in an attempt to stop anything from happening. She tensed up for a few seconds with her eyes clenched shut, and eventually sighed when she managed to get that aura pressed up tightly against the back of her diaper. “Nnnfff!~”

“Now, with Sunburst taking a little break to enjoy the handiwork of my device…” Trixie went right up to Starlight’s box, taking only a second to make sure her friend was staying on cue. Fortunately, she gave a playful smile to the crowd while effortlessly closing off the bottom section with that fake blade. “How about we cut this assistant down for size?~”

Starlight was lucky that she got the fake feet set up in time, but now it was harder for her to keep her eyes open. She was clearly straining hard, not even able to smile while grimacing badly. She had to take a breath before pulling herself back even more, despite the fact that her horn’s magic was sputtering from her faltering focus. The magic holding her diaper so close eventually gave out, just when she had to pull her legs back even more so her thighs were pressed up against her breasts. “Aaahh!~”

That heated gasp came just when Trixie shoved down the second blade, thus separating the three pieces for the big reveal. Starlight could barely even focus on the applause or impressed “oohs,” and just laid in that hunched position with her face becoming redder. She desperately tried to re-light her horn, but she couldn’t get a proper grip without having a good idea where her ass was positioned. It didn’t help when she was distracted by an even harsher grunt from Sunburst from across the stage.

“Mmmphhh…” The stallion was hanging with his knees quivering in dread, and his cheeks clenching harder than they ever had before. He could only watch as Trixie rolled out the three pieces of Starlight’s act across the stage, making sure to take her sweet time while doing so. He was trying to breathe at a slow and concentrated pace, since he couldn’t use his magic to hold up his rear while he was up against the wall. And to make matters worse, it didn’t even seem like his bondage was even necessary while Starlight continued to be the focus of Trixie’s act. “Nnnghh, oh come on, come on…”

Sunburst’s knees quivered and tried to pull in closer together, despite his ankles being firmly braced to the device. He whimpered painfully enough to make a couple ponies glance at him worriedly, but none of them tried to say anything about it. After a long and shuddering sigh, he struggled to remain still while Trixie spoke.

“Now with the mare successfully cut in half…” She used her magic to close those fake trap-windows while Starlight continued to fidget in place. “We’ll just have to--”

“OooOOOoohhh!!”

A harsh-sounding groan from Sunburst, followed by some low and guttural noise akin to a muffled growl, distracted Trixie long enough to look back at him with a raised brow. The stallion winced and hung his head, but the rest of his body remained tense after that brief slip. It was thankfully just gas, but he knew for a fact that the next one wouldn’t be. Starlight was looking back at him for a moment with a silent sigh, secretly pitying his predicament enough to temporarily forget about her own--

“HNNGHH!!”

Her gasp was accompanied with her eyes shooting wide-open, and her pupils shrinking immensely. Since she was still hunched up in her tiny little section, she was basically pressing down on her strained gut already; and as soon as she dropped that concentration the slightest bit, her muscles stopped contracting at the worst possible time. She could only be fortunate that Sunburst’s accidental toot got a lot of the attendees to laugh, since it helped to cover her own shuddering groan. Her eyes clenched tightly, but that proved to be the only part she could control as she breathed out hoarsely. “Hnnnnnaaaaaahhh!~”

Her head lurched up the tiniest bit from the outside of the box, while her rear end raised up inside with only the briefest push. Even with a full crowd watching her like a display piece, she wasn’t able to hold back that mudslide while her face grew a beet-red. Her breath came out as faint and silently as it could, but she still showed a great amount of distress from her bowels giving away. Just as Trixie went back towards her, Starlight shamefully grunted and kept her eyes closed.

“Nnnnnghhhhh…” Since she was technically “hidden” from view, the mare could only think of her temporary relief as she gave up the fight. As soon as she relaxed, the bottom of her padding immediately pushed out and hit the inside of that barrier keeping her in place. She shivered with a strong skew of her head, and tried her hardest not to wince as she felt that soft and mushy warmth hitting her rear in ways it never should. The disgust showed more blatantly on her face, even as she remained frozen in guilt and literally stewing in her own filth. Her whole body writhed inside the tiny box, while her diaper continued to fill out and reveal a thick, lumpy mass bulging from the back.

“Don’t worry, you’ll get your footsies soon enough~” Trixie was skilled enough to get all three pieces rolled back together with ease, and got the prop reassembled without the need of Sunburst’s help. She even used her magic to discreetly switch out the fake feet with Starlight’s real ones, since the mare was too busy reeling in disgust to realize she was still part of the act. She gasped in sudden shock when she felt herself being pulled back through the device lengthwise, but quickly reassessed herself enough to get back to reality. Despite having just shit herself in front of a whole crowd, the show must go on…

“TA-DAAA!!~” Trixie proudly revealed the uncut Starlight when she finally reopened the top lid, and pulled her friend out for the audience to see. Starlight was frozen in petrified fear with her smile as unnatural as a horror movie villain; it didn’t help that when she emerged from the box, she had to sit upright in the box with all her weight directly on that fresh mound she just made.

“MMMPHHH…” Her eyes shot wide-open, and her body trembled hard from the intense discomfort she felt sitting in her own mess. She wasn’t sure how much she actually let out, but she could definitely feel the sloppy mass spreading out to cover every inch of her ass with that squish; it even seeped around to her front and sides, causing her to groan in remorse of how to clean that up later. But alas, with literally dozens of ponies looking right at her, she almost felt like she deserved an acting award for how well she handled that sensation with a forced smile. “... hhhhnnnnnnn…”

If it was any benefit, there wasn’t much of a “bulge” anymore when she finally exited the box. She tried being as careful as possible, even getting out of the box at an awkward angle so she didn’t flash her messy diaper by accident. Luckily, since she already patted it down well enough with the aid of gravity, her ass actually looked a bit flatter with an obvious press-mark holding the seat of her suit in place. She ended up standing quite rigidly when she was back on her feet, and she had to waddle a bit more slowly to get beside Sunburst in his spinning device. Unfortunately, the stallion groaned and looked down at her after taking a couple sniffs. “What the… ugh!”

Starlight just hung her head in shame. “... I know…”

Sunburst looked like he wanted to say something, but he couldn’t when he saw how upset she was looking. Not to mention, he was barely holding on as it was, and was certain he would be having a similar outcome soon enough. When Trixie walked back towards him, he took a deep breath and clenched his eyes shut; of course, taking that breath also made him wretch and lurch his head. “UGH!”

Starlight sincerely hissed out, “I’m sorry!”

“Alright, for my NEXT act…” Trixie could’ve easily exasperated things with just a single hard spin of Sunburst’s circular bondage. But instead, she caught both her assistants by surprise when she only spun the frame a hundred and eighty degrees. Sunburst gasped and yelped out when he found himself hanging upside-down, with his legs still spread-apart and his diaper now even more focused on stage. Trixie then grabbed hold of her other assistant by her wrists, and made her wince when she was forced to waddle forward to feel more of that disgusting squish. “... I think I’m going to need you riiiiiiiight here~”

Trixie placed Starlight right in front of Sunburst in the device, not seeming to realize how horribly they were now positioned. Sunburst winced in pure horror, as he was now literally at face-level with that mushed-down and messy diaper of his friend’s. Starlight groaned and tried not to fidget in place, but she was already planning out her lengthy apology letter to Sunburst later today. She wished she could step aside or move a few inches back from his wrinkled snout, but Trixie was keeping her firmly in place with her hands against the mare’s padded hips. The magician took only a moment to look her up and down, and smirked upon seeing that blushed and conflicted grimace on Starlight’s face.

“I just need you to stay right here.” Trixie patted her hips firmly, emphasizing that her feet were meant to be positioned there to keep her in that uncomfortable gait. Sunburst could be heard whimpering from behind her, but the magician walked right off unaware of his torment. Sunburst tried to reel his head away, but he was still given a full view of the aftermath of his friend’s accident. Meanwhile, Starlight was grateful she wasn’t able to see his face, or vise-versa for that matter; otherwise, there was a good chance that he’d notice the look of horror looming over her slowly…

Trixie began to talk with the audience with some long-winded speech, which gave Starlight enough time to realize her biggest issue yet. She was worried that pooping herself would be the worst-case scenario of a moment like this, which would’ve meant at least a little reprieve for the remainder of the shows. But alas, now the mare was feeling a more grave realization that made her face pale in dread. Much like her bladder, which was still feeling like it was straining from newfound pressure, Starlight couldn’t deny that other sensation nearly as convincingly. If anything, it was like some sinister spell instantly re-filled her from the inside…

Despite just using her diaper both ways, she was still needing to go. Bad.

“... Mmmmphh…”
“Oh noooo…”

Sunburst clenched even tighter, but his redirected gravity did little to alleviate his own building pressure. He had no idea what would happen if he went now, but he was too scared to find out the easy way. It would’ve been hard enough to concentrate while upright and away from his friend’s padding, but now it was basically impossible.

“Now, let’s see how well these ponies can stay still~”

Trixie revealed an egg she had discreetly hidden inside her cape. Without warning, she threw it full-force at the two assistants. It hit the board with a messy spat, nearly striking Starlight’s face as it exploded a few inches from her head. She screamed out in a panic, clearly not expecting her friend to do that, and temporarily forgot her sudden compulsions.

“AAHHH!! Mmmphhh~”

Less than a second after that shriek, Starlight gasped and nearly bent her knees by instinct. She may have remained standing, but her whole body writhed as she tried not to buckle over or show too much faltering. Unfortunately, as soon as she reacted to that egg, she ended up pushing out something a bit unexpected from her backside. Sunburst was left frozen with his muzzle clenched, and could only close his eyes to ignore that small bulge that newly appeared from her rear.

“Just to test your reflexes a bit~” After her little quip, Trixie revealed a large bundle of bananas she had hidden near the curtains. The audience were already laughing and enjoying themselves, although thankfully not because of either of the unicorns’ garments. Starlight whimpered and kept her mouth tightly shut, while Sunburst just blushed and tried to keep himself similarly tight. But alas, both ponies were caught off-guard once more when Trixie used her magic to give Sunburst a playful little spin…

“OoooOOOHHH!!” Sunburst gasped and tried to brace himself, but his head was immediately jostled by Trixie’s antics. He yelped out while spinning at an abnormally fast rate, forcing him to be face-to-face with his audience and Starlight’s messy rump. The motions also seemed to fan the stench quite a bit, and his muzzle wrinkled up in disgust and made him gag a little. Meanwhile, Trixie kept the audience laughing when she tossed a couple half-peeled bananas right at her friends

“AAHHH!!” Starlight flinched again, but was thankfully unhit by either of the bananas that splattered against the spinning frame. She ended up lurching over a bit more, and groaned to herself with a disgusted grimace. Her body overtook her composure for only a second or two, but it was just enough time for another mound to sneak out and add another bulge to the back of her padding. She managed to pull herself back up with her fearful smile intensified, just as another banana hit close enough to her head to really test her nerves. “... nnnnnnghhhh…”

“AAAAaaaaAAAAaaaaAAAAaaaAAAaaaahhhhhh!!”

Sunburst kept spinning around like a record player gone berserk, but was miraculously untouched by any of those wayward bananas. Unfortunately, due to his senses being bombarded in so many ways from his spinning, there was no way for him to clench his cheeks and hold anything back. His eyes clenched shut, and his muzzle hung open to belt out a long and dire moan of defeat. “OooooooOOOOOAAAAAAAHHHH!!!~”

Sunburst nearly received whiplash from how abruptly Trixie stopped the device, right as the stallion was back to hanging upright and facing the cheering audience. Even after the whole bundle of bananas was thrown at them, neither of her assistants were even grazed by the fruits while they clung to the wall with the peel-ends sticking out. His face was as red as a tomato, and spirals could be seen in his eyes while his brain was trying to overcome his dizziness. His knees tried to bend in together, but nothing could be done while they were spread so wide apart. Furthermore, his moan continued on as he lurched his head down, and his legs tensed up for a hard push. “NNNNGHHHH!!!”

Unlike Starlight, who was able to hide her emotions fairly well during her incident, Sunburst wasn’t too lucky. He groaned with that uncontrollable compulsion that swept through his body, forcing him to expel that pressure from his gut while it was at its worst. Starlight desperately tried to remain in front of her friend, but her face contorted into a revolted wince the moment she heard that distinct, crinkly noise right behind her head. It was fortunate that she didn’t lurch her head down from the smell alone; otherwise, there was a good chance that the whole audience would’ve been able to see the massive sag that sunk out from between Sunburst’s legs.

The lycra material may have been good enough to hide any obvious discoloration, but it was far too elastic to hide what the stallion had done. Halfway through his dire cry of release (which was thankfully muffled out by the audience), the bottom of his diaper took the full brunt of his messing due to how tightly he was pinned against the back. A very visible, lumpy bulge was trying its hardest to poke through the lycra, but Sunburst ended up gasping really hard when his friend took action. Before anypony (including Trixie) could notice that Sunburst crapped himself, a bright aura of Starlight’s magic formed into a hand and pushed up between his legs.

“OOOOHHHH!!~” His eyes shot out wider than his glasses for a second, and he writhed hard in his bondage while feeling that hot mess pressing up against his ass and nethers. The sensation was absolutely disgusting and mortifying all in one, but Sunburst endured that for only a second before Starlight turned off her horn. To her credit, she managed to press in hard enough to effectively spread everything around, thus leaving his backside looking less obvious than her own. Unfortunately, the stallion hadn’t even fully processed what he just did, and was now left to bask in that shame like a toddler who failed potty-training. “Mnnnghhh…”

“I’m sorry…” Starlight kept her eyes out at the crowd while muttering that sincere statement to her friend. She sighed through her nostrils worriedly, but decided to ask, “Did… Did you do it too--”
“Yes, now shut up.”

Sunburst growled out that response just out of Trixie’s earshot, but both unicorns remained silent when she came up and unlocked the stallion from his bondage. He groaned with a heavy cringe when he stood back on his feet, stumbling a little from the dizziness. He could feel all that filth caked on to his ass and elsewhere, and shuddered from the unpleasant nature of it all. He could only imagine that Starlight was dealing with the same, so he shot her a sympathetic shrug when the two were left standing together.

“Come on, guys. Don’t hold back now…” Trixie got up between her two friends, and whispered with a grin, “There’s still one more show after this one~”

Both unicorns gulped in fear, their pupils visibly shrunken with the same horrifying realization. When Trixie walked away to get her next props, the friends stared at each other for a split-second with the same worry in their heads. And in that moment, both of them could tell they were thinking the same thing…

Trixie wasn’t finished yet. And neither were either of them.
