Diving Into Desperation
It was another cold day of winter in Ponyville. The Hearth’s Warming festivities were coming to a close; like any other year, the celebration had been fun and joyous, but the population of Ponyville was happy to prepare for the ushering in of spring, though there were a few weeks left before that time really came.
However, Rainbow Dash wasn’t planning to move on so quickly.
This winter, she’d made her own little “advent calendar” of pranks she was pulling on a multitude of ponies, especially targeting her closest friends. She’d meticulously planned each one, which wasn’t like her - planning wasn’t exactly her forte. But she wanted to make this a legendary season of mischief, and she’d succeeded. This wasn’t the end, though - there was still one more, one last prank that would catch its subject entirely off-guard due to it being done after the advent calendar should’ve already ended.
Unfortunately for Rainbow Dash, the subject of this prank, Twilight Sparkle, was already a step ahead of her.
One day, after making sure Rainbow Dash was fully distracted with one of her pranks, Twilight flew up to her house, snuck in, and found her plans, hoping to get back at her when she least expected it. This last prank was the perfect time for this payback.
The alicorn was under her bed, biding her time, patiently waiting for Dash to begin the prank. It was the most complicated prank yet: the pegasus was going to bring clouds into Twilight’s house while she was supposed to be gone for princess business, making the whole castle foggy. Then, Rainbow would jump out and scare Twilight, like she was in a horror novel. She had to admit, it was a little bit clever, but not clever enough.
Twilight heard her window open, followed by sneaky hoofsteps on the ground; Rainbow entered, a clearly mischievous look on her face, her teeth clenching a large cloud that she quickly ranked through the window frame. Any second, she would set off the trap…
“AGH!” A few vaguely magical sounds rang out in the room, accompanied by a distressed scream from Rainbow. Twilight snickered, crawling out from under the bed; she casually swept the cloud back outside using her magic, and then looked at her prey.
“Wow, Rainbow Dash - looks like you really should’ve watched where you’re going~” She chuckled. Rainbow Dash was bound to the ground, held down by a number of purple-ish, translucent, magical chains. “I wasn’t sure if leaving the rune circle out in the open was going to work, but I should’ve figured you’d be too focused on your prank to watch where you were going.”
“Twilight, what did you do!?” Rainbow asked, ruffling and squirming, trying to get out from the trap, though it was futile, of course. “How did you know I was going to be here?!”
“Don’t worry about that - all you need to know is that you should be more careful when you’re trying to prank me~” Twilight’s horn glowed. “We like your pranks, but you did way too many this winter - we’re getting tired of them. So, I figured I’d teach you a little lesson~”
“Alright, alright! Lesson learned!” Rainbow blushed; she’d probably gotten a bit too excited and went overboard. It wasn’t anything new for her. “Now please undo these chains, they’re making my back itch!!”
“Oh no, we’re not done yet~” A disposable white diaper floated out from under Twilight’s bed, unused and clean, fresh out of the packaging. It unfolded itself and drifted towards Rainbow, surrounded by Twilight’s magic. “Sorry, but I really want to make sure this one sticks, Dashie~” The diaper floated to Rainbow Dash’s backside as she squirmed even harder.
“Woah, hey, what are you doing with that thing!? Twilight, this is weird!” The diaper began to wrap itself around Rainbow’s arse. “There’s no way I’m going to wear this thing! You’ve gotta be kidding me!!” Despite her struggling and protesting, the diaper was soon strapped tight to Rainbow’s behind. To seal the deal, Twilight blasted a shot of magic at it, causing the straps to bind together with a small purple padlock.
“You’re not getting a choice this time~” A purple brace appeared around Rainbow’s back hoof, and a set of chains wrapped around her body, tying down her wings. “And with that, you won’t be able to leave the walls of my castle, or fly~ Plus, I’ll know where you are at all times~” She smirked; the chains dissipated, aside from the ones wrapped around Rainbow’s body, holding her wings down. “Be a good girl, and this won’t have to last too long~”
“This is insane, Twilight!” Rainbow tugged at the diaper, but to no avail. “This is a complete overreaction to a harmless prank!”
“Hmm… well, maybe it is… but that’s not really the point. I mostly just wanted to mess with you~” Twilight approached Rainbow Dash and lifted her chin, holding her face up to Twilight’s face. “We’re going to have a lot of fun together, Rainbow Dash~”
Rainbow blushed harder; Twilight might’ve been the same size as her, but right then, the alicorn felt a whole lot bigger and taller. She gulped. “This is going to last for a while… isn’t it?”
“Ha! Without a doubt.” Twilight moved her hoof and walked past Rainbow Dash, reaching out and touching the diaper as she did so, hearing it crinkle under the pressure. “You really look ridiculous right now~ I wonder what the Wonderbolts would think if they saw this~”
Rainbow bit her lip. “Please don’t let anypony else see me like this…”
“As long as you’re good, I’ll make sure nopony else sees you… probably~” She closed her eyes and concentrated; a magical collar with a leash attached appeared around Rainbow’s neck. “Come on - I have some chores I need to do. I’m not letting you out of my sight until… well, you’ll find out~”
Rainbow tried to pull off the collar, but it stayed right where it was. “Come on, you’re treating me like one of Applejack’s farm animals!”
“I’ll stop treating you like a farm animal when you stop acting like one~” She grabbed the leash with her magic and pulled Rainbow Dash along; the pegasus quickly began walking to avoid being tugged down the hallway.
And, as Rainbow was walked towards the castle’s library, Rainbow had a sudden and very unfortunate realization. “Um… Twilight?”
“Yes, Rainbow Dash?”
“How am I supposed to use the bathroom in this?” Rainbow bit her lip; already, her hind legs were beginning to quiver. It wasn’t a detail she’d normally divulge, but her bladder was already starting to get quite full. “Are you going to take it off every time I need to?”
Twilight chuckled, stopping to turn back to the pony. “Oh, poor Rainbow Dash~ What do you think a diaper is for? You can use the bathroom anytime you’d like, but that diaper isn’t coming off no matter what~”
“Wait, I have to actually use the diaper, too!?” Rainbow’s entire face turned red. “And right in front of you!? That’s so embarrassing!”
“I would normally say something about how you don’t have to worry about me judging you for something like that, but, well… yes, you’re right. It is very embarrassing.” Twilight’s smile was uncharacteristically mischievous and a bit horny; she was enjoying this a lot already. “And I’m going to make sure I never forget how you look when you finally do it~”
“Twilight… Y-you aren’t being serious, right? This has to be a joke - I’m sure you’re going to let me take this thing off when I actually need to use the bathroom.”
“You’ll find out whether I’m joking or not soon enough~” She began walking again, still pulling Rainbow Dash along. “Come on~”
—-------------------------
The walk wasn’t too bad at first, minus the heavy weight of the humiliation burning in Rainbow Dash’s cheeks. This went beyond anything embarrassing she’d ever experienced before - even the Wonderbolts’ hazing wasn’t nearly this bad. She almost believed this was a dream… or, at least, she hoped it was a dream.
The walk got much worse as it went on, due to Rainbow’s bladder seeming to get more and more desperate to release its contents. She could tell it was filled to the brim with urine; she couldn’t help but keep her head down and try to keep her thighs pressed close together, her hind legs quivering from the struggle. Intermittent pings of pain rushed through her body, all centering on her bladder. “Twilight, I-I really need to use the bathroom…”
“I’m not stopping you~” the princess responded, leading Rainbow Dash into the library, a grand room filled with novels and tomes - practically heaven for Twilight. “Do it whenever you’d like~” She dragged the desperate pony over to one of the armchairs, slipping the leash under one of the chair’s legs so that Rainbow wouldn’t be going anywhere anytime soon. Her horn glowed, and books that had previously been sitting in piles on the floor began to rearrange themselves on the shelves.
“Like… r-right now?” Rainbow couldn’t move far from the chair at all; the leash was barely five feet long. She paced back and forth, trying to distract herself from her need to urinate. Her back legs were shaking even harder now; there was a constant ache in her pelvis. She’d never needed to go this badly before, and it was really starting to seem like she wouldn’t be able to hold it. It completely went against her ideals and her image of herself to have an “accident” like that - she focused as much as she could on holding it in, eventually sitting in place with her back hooves slightly spread, her front hooves pressed against her crotch, crinkling the diaper and putting pressure on the area. Sweat beaded on her forehead. “If I do end up… y’know… wouldn’t it make a mess?”
“Not with that diaper on - it should absorb everything. And if not, I’ll just have you clean it up.” Twilight pulled a book from the shelf; the front cover read, ‘An Advanced Guide To Pony Bondage,’ one of many in a series by the BDSM-focused author, Moonscribe.
“Huh… I never expected you to have something like that in your library,” Rainbow teased, trying to take control of the situation. “Looks like you aren’t as pure as you seem.”
“Are you really that surprised~?” Twilight responded, snickering. “Where did you think I learned about this stuff from? Don’t worry - you’re going to get a chance to learn a bit, too~ In fact…” Twilight put the book down and stood up, walking over to Rainbow and using a hoof to move one of her front hooves aside. She got up in Rainbow’s face, far too close for comfort. “You look like you’re really struggling~ You look cute with your legs shaking like that~”
“T-Twilight!!” Rainbow blushed; she tried to back away, but the leash kept her in place.
“Getting close to losing control~?” Her horn was slowly enveloped in purplish light. “Why don’t I make it a little bit easier for you~?” Ropes of purple appeared in thin air and quickly tied themselves around the pony; first, they attached to Rainbow’s front hooves, pulling them behind her back and tying them tightly together. Second, they grabbed onto her hind hooves, one rope for each, pulling them apart. “There we go~” She prodded Rainbow’s crotch; the pegasus squirmed, trying desperately to hold it in still, but this position made it far harder. If she was in a battle with her bladder, then Twilight had just stripped her of all her weapons and armor. The open position made her body feel naturally inclined to let out what it was holding back. “It’s only going to get harder the more you resist~ Why don’t you just let it out and relieve yourself~?”
“Nnngh…” Rainbow’s limbs were held tightly; she couldn’t move an inch. “Twilight, please, I-I really don’t think I can hold it for much longer!”
“That’s fine with me~” The alicorn pulled a footrest over and sat in her armchair, laying her hind hooves across the rest and sitting loftily, looking down on Rainbow Dash with a dominant and mighty gaze, a look that you’d expect a pony to give to a cute bug, something lowly but entertaining. “I told you, this isn’t a joke~”
Rainbow lowered her head bashfully; she kept squirming and moving, her hind legs now fully quaking. Her bladder felt like it was going to pop open. “Oh no…” she murmured to herself. She bit her lip and focused all of her mind on holding it, even as the pain increased; she could feel the urine moving through her system, getting closer to her slit, rushing to the point of release with expediency. She had to keep pulling it back, again and again, as though it were an animal that refused to simply be tamed.
But eventually, it wasn’t enough.
Her whole body shivered; she felt the liquid breach her defenses, the lightest little leak of urine making it out of her slit and touching the diaper. And with that, her dam was entirely broken - her efforts to hold it back were rendered entirely futile as her body forced itself into a state of relief and relaxation, emptying her bladder, regardless of how she felt about it. She let out a loud, involuntary sigh of relief, her face glowing like a red star, as urine flooded her diaper.
It was warm and wet, as to be expected; it felt weird against her body, and it also felt so wrong to be doing this, like she was breaking a taboo, but she couldn’t help it. At the same time, the relief was so strong, she couldn’t help but enjoy it, huffing and panting from the effort of holding it back. The light sound of the stream pittering against the diaper material filled the library as Twilight smiled wider, chuckling as she watched the experience. “I knew you weren’t going to make it much longer~” the alicorn teased.
The diaper slowly turned to a golden yellow hue on the outside; the ropes on Rainbow’s front hooves disappeared, letting her cover her face in embarrassment, though Twilight still made sure the diaper was in full view. It turned to a darker shade, getting more and more full, the pissing taking almost an entire minute before it finally trickled out. “Aww, poor Rainbow Dash~ Looks like someone had a little… accident~” Twilight stood from her armchair and approached again, chuckling sinisterly.
“I-I…” Rainbow was so embarrassed, she could hardly get a word out of her mouth. “P-please don’t tell anypony…”
“Poor, poor Rainbow Dash~ Don’t you worry - I won’t let anypony know that you peed yourself right in front of me~” The alicorn giggled. “You look so much cuter this way, you know~”
The pegasus felt like she was on fire; the embarrassment was unlike anything she’d ever experienced before. She was almost on the verge of tears. “I-is this enough? Can I finally take this off?”
“Hmm… I don’t know…” Twilight held a hoof to her mouth and smiled, showing her teeth. “I think it’s going to take a while longer before I’m sure you’ve really learned your lesson. Sorry, Rainbow Dash… but I think you’d better get used to wearing a diaper~”
“How long do I have to wear this?” Rainbow asked, not quite as confident as usual.
Twilight put a hoof on top of the pegasus’ head and pushed it down to the ground, stepping on it, making it so Rainbow had to look straight up to see the princess towering over him. “Until I’m satisfied~ And, unfortunately for you, I think that’s going to take a while~” All of the binding on Rainbow, except for that on her wings and the diaper, disappeared, only to quickly be replaced with a chain attached to the ground. “I’ll change your diaper eventually… but I want to see more than just you pissing~”
“You don’t mean…” Rainbow shuddered, standing and stepping back as Twilight removed her hoof.
“I do~” Twilight sat back in her chair, opening the book again. “Good luck~”

Rainbow Bashful
Rainbow Dash was not the type of pony who enjoyed sitting around doing nothing.
In fact, she was the exact opposite. To her, sitting around and doing nothing was basically on par with being dead - she couldn’t stand it. Boredom was torture. She’d do anything to entertain herself.
But right then, all she could bring herself to do was sit silently.
Rainbow Dash had just done something that was the exact opposite of cool: she’d pissed herself, while wearing a diaper, right in front of Twilight. And what’s worse, Twilight had clearly enjoyed it… and she wanted Rainbow Dash to go even further.
It had only been a few minutes since the first accident. Rainbow Dash was lying on the ground, trying not to look at Twilight, her whole face red as a strawberry. Her diaper was still full and used; the bright yellow, lemonade-like hue was a clear indicator that it was far from clean. The warmth and dampness, along with the squishing sensation it made whenever she moved, grossed the pony out, just reminding her of her humiliation. “Come on, Twilight, can’t I at least put on a new diaper?”
“Don’t make me put a muzzle on you, too,” Twilight threatened, sipping a cup of coffee. “I told you - I’m not changing you yet. I’ll change it once you’ve made full use of it.”
“Ugh, what does that even mean!?” The pegasus rolled onto her back in frustration. “Twilight, this is horrible!”
“You’re gonna figure out what it means soon enough~”
As if on cue, Rainbow Dash felt a bit of pressure in her digestive system, especially focused on her stomach. Her embarrassment only grew as she realized what it was - she normally wouldn’t have felt any sense of shame about this, but in her current situation, it was hard not to. “Twilight… I really need to use the bathroom…” the pegasus said, turning to look up at her friend. Twilight was like a princess sitting on her throne. “Like, really badly this time. Worse than before.”
“Ah, finally.” Twilight closed her book; her horn began to glow brighter. “I was waiting for this~”
Rainbow Dash’s eyes widened in fear when she saw the alicorn’s horn glow; she was beginning to associate that with being bound and tied in different ways. “Um, y-you’re going to let me actually use the bathroom now, right? Making me… do… this…” she motioned to her bright-yellow diaper, “Was bad enough. You aren’t going to make me do that, too, r-right?” She sounded unsure as she spoke; she had little confidence at this point. Twilight’s humiliation was ruthless.
“I’m not going to make you do anything~” A magical bar formed between Rainbow’s hind legs and between her forelegs. Each bar had a shackle on the end, which quickly connected to the ankle of the corresponding leg, and stretched them out, holding them firmly in place while spreading them wide. Her body slowly floated from Twilight’s magic until it was in a standing position, and she then floated in front of the armchair, the hoofrest moving out of the way to make room for the pegasus. Twilight propped her legs on Rainbow Dash’s back, using her as her new hoofrest. “But, well, I’m not letting you take your diaper off… and I want to make sure you stay close, so I’m not letting you move too much either~” A magic rope tied Rainbow’s tail down to her legs, and then collared and leashed her head yet again. The alicorn placed the leash underneath of her on the chair. “You make for very comfortable furniture~” Twilight said, snickering. “Rarity would love this. Maybe I should give her some ideas~”
“Twilight…” Rainbow Dash couldn’t even squirm like this; she was being weighed down by Twilight’s hooves, her own hooves entirely restricted, even her tail and head unable to move. “I-I don’t think I can hold it that long. If this is a joke, this would be a good time to wrap it up!” The pressure was increasing; she felt an ache in her stomach. Instinctually, she wanted to put a hoof to her belly, but she couldn’t, of course. All she could do was stand and let it happen, let the pressure build and mount. Even clenching her rear wasn’t doing much to stop it; her defenses were slowly waning, slowly being broken, as her body kept pushing.
“Do you really think I would do all of this for a joke~?” Twilight snickered. “Don’t try to hold it in - I’m a very patient pony. I’ll happily sit here, all day, using my new, fuzzy hoofrest, while you stay in that position, all bound up by metal bars and ropes~ I’m sure that’s not too comfortable - I’ll undo it, as soon as you just let it out~” Indeed, Rainbow was in an incredibly uncomfortable position. The worst part was her hind legs being spread - it made it nearly impossible to hold anything back. All she could do was use her sheer force of will to stop her guts from emptying themselves into the damp material of the once-white diaper… and that willpower was not doing well for her at that moment.
The pressure mounted; she focused, letting out little groans, as her stomach continued to ache. Her body was begging her for relief, even harder than it had before, and it wasn’t going to hesitate to break through her resistance if it needed to. At this point, it was really only a matter of time until the pegasus finally lost all control… right in front of Twilight… for the second time. She closed her eyes tight and gritted her teeth. “Twilight… p-please, please let me use the bathroom!”
“Nope~” the alicorn simply replied. “Like I said, you should just let it out~ It’ll be so much easier that way.” She closed her book. “In fact… it seems like your body’s getting pretty close to listening to my advice, regardless of whether or not you want it to~”
Again, Rainbow’s legs were shaking; she breathed heavily, sweat dripping down her face. “Ah… I-I can’t hold it!” she proclaimed, her rear shivering and shaking. “Twilight!!”
“Call my name all you want - it won’t change anything. It is cute, though~”
“Hnngh…” She let out one last simple grunt as she tried to hold it back… but her muscles were now ignoring her brain. Suddenly, the pressure began to move… and then it began to decrease…and Rainbow stopped shaking, suddenly letting out a mix between a sigh and a moan in relief. Mildly wet sounds filled the quiet air as her diaper bulged out, suddenly turning a dark shade of chocolatey brown on some parts outside, though still retaining the yellow in other spots. She bit her lip and kept her eyes closed, wishing she could hide her face or fly away, as her diaper began to sag and expand, swelling as it got fuller with each passing moment.
“Hahaha~!” Twilight laughed out loud, getting up and running to look at Rainbow’s backside. “I can’t believe it - you actually did it~” She covered her nose as the horrid scent filled the air. She’d never seen Rainbow Dash in such a pathetic, humiliating state. “Oh, you poor thing~ You’re like a foal who can’t find her mother~” She walked to Rainbow’s front, laughing at her ever-brightening blush. “Aww, did poor Rainbow Dash have a little accident~? Does somepony need to have their diaper changed~?”
“T-twilight…” Rainbow’s voice was squeaky; she looked away from Twilight in shame, only for the alicorn to put a hoof against Rainbow’s face and move it back.
“You’re so cute like this, you know that~?” Twilight giggled. “Ahh, I wasn’t going to take any pictures, but…” A camera floated into the room; the alicorn held it in her hooves. “I have to get at least one~” SNAP! The alicorn took a quick photo of the scene, an instant film picture soon coming out. “I’m going to be keeping this~”
“P-please don’t let anyone else see this…” Rainbow bit her lip, opening her eyes a bit, just to see Twilight’s dominant, confident, sadistic expression.
“Don’t worry, Rainbow - I’m keeping this all to myself. Not a single other pony will know about it, I promise~” The picture floated back into her room, along with the camera. “Well… I might tell our other close friends that I had some fun toying around with you, but I’ll leave out the details on the diaper and your unfortunate little accidents~ Unless, of course, you decide you want more from all of us after getting taste~”
“No way,” Rainbow Dash immediately responded, shaking her head. “I can’t imagine ever wanting to do this again.”
“We’ll see how long you stick with that~” The bars between Rainbow’s hooves disappeared, as did the rope on her tail, though the leash remained. “Come on - let’s go to the bathroom. I’ll wash you off and get you a nice, fresh diaper~”
“W-wait, I have to put on another one!?” Rainbow’s mouth fell open. “Twilight, please, I swear I’ve learned my lesson! I’ll never prank you again, I promise!”
“It’s not about that, Rainbow Dash - I just want you to be a little more mindful about spacing your pranks out so that they don’t get overwhelming. A little prank here and there is fine, but an entire month makes it excessive and annoying. Maybe you’ll get what I mean after you’ve been forced to use diapers for, say… I was just going to do 24 hours originally, but let’s try a week~”
“A week!? Twilight, I have things I need to do! I can’t go around performing with the Wonderbolts in a diaper!”
“You don’t need to worry about that - I already called and said you’d come down with a bad flu. They’ll manage without you for a little bit, and when I’m done with you, you can go right back~” Twilight grabbed the leash and pulled Rainbow along, toward the bathroom. “Come on~”
“Mmm…” Rainbow put her head down and followed, still in disbelief. She already felt like she’d experienced one of the worst things she could imagine, and now, she was being told she’d have to deal with it for a whole week. But, then again… at least it was Twilight, her close friend, and not somepony else. At this point, she probably should’ve been questioning her friendship with Twilight… but it wasn’t like this was their first time doing kinky stuff. The mane six as a whole had explored some more sensual stuff together in the recent past; Rainbow Dash should’ve realized that Twilight’s teasing wasn’t a joke. No matter how much Twilight dominated the pegasus, Rainbow still saw her as a very close friend… and a very hot one, too, to the point where it would be difficult for Twilight to do anything that could make Rainbow feel otherwise. Even when the alicorn was going as far as to humiliate her to this extent. That didn’t stop it from feeling like a punishment, though, and that was obviously the princess’ intent.
“Here we are.” Twilight tied the leash to the bathroom’s handle on the outside. “Wait here for a second - I need to use the bathroom~” She put plenty of emphasis on that statement, making sure to rub it in.
Rainbow grumbled as the alicorn went in; she tried not to listen to the sounds of Twilight enjoying her time in the bathroom, but the loud flushing was difficult not to notice as the pegasus sat in her full, dirty, used diaper. Eventually, the alicorn came out, flipping her mane, looking refreshed and satisfied, even letting out an exhale of relief. “Do you really have to rub it in so much?”
“Of course~ I’m not the one who needs to be punished, am I?” She pulled Rainbow into the bathroom. “Hop into the shower for me.”
Rainbow did as instructed; she instinctively went to use her wings for that action, but of course, they were still bound, resulting in only a lame, sad little jump. Twilight put a hoof to her mouth as if trying to hide her obvious amusement; Rainbow stepped in, successfully this time.
“There we go,” Twilight said. She used her magic to remove the diaper, the padlock unclicking and disappearing. The water turned on; Rainbow went to start cleaning herself, but as she did, she froze in place, Twilight’s magic paralyzing her whole body. “Hold on~” Twilight stepped into the shower, grabbing the shampoo and putting it on her hooves. “I can’t let you clean yourself - how can I trust you to do that when you can’t even hold in your own waste~?”
“Twilight, you can’t be serious. I haven’t had another pony clean me since I was a foal!” She sheepishly looked back at the purple pony, who was now rubbing shampoo into the pegasus’ lower back.
“You probably haven’t used a diaper since you were a foal, either, but that isn’t stopping me~” She moved her hooves down, nearing Rainbow’s private parts. Even if they didn’t normally wear clothes, ponies still tended to consider those parts more private; Rainbow’s heart sped up, her blush glowing radiantly.
“T-Twilight, b-be careful back there!”
“Oh, oops.” The alicorn moved her hooves back. “Do you mind, Rainbow? I won’t touch you there if you’re not comfortable with it. But if you let me, I think you’ll enjoy it~”
If Rainbow possibly could’ve blushed harder at this point, she would’ve. She gulped. “I’m surprised you’d make me use a diaper against my will, but you’d still ask about that…”
“I still care about you, Rainbow - I wouldn’t touch you in that way without your permission. The diaper is different, trust me - that’s just a bit of harmless bullying~”
Rainbow wasn’t sure she agreed with Twilight’s assessment… but still… “Y-you can… g-go ahead…”
“Perfect~” She soon rubbed her hooves down Rainbow’s crotch, passing over her privates; the pegasus bit her lip, careful not to let out any sounds of pleasure or enjoyment, even though the alicorn’s touch to such a sensitive area sent shivers up her spine in the perfect way. Though, before she knew it, it was over; Twilight had cleaned her off, including her rear and privates, and the alicorn even went to the effort of drying her off by hoof, no magic required. “There we are~ Good as new~”
“Does that mean we’re done?” Rainbow asked, hopefully.
“Nope!” Suddenly, a new diaper flew into the bathroom, and immediately wrapped around Rainbow’s privates. “But for today, I’ll let you off the hook. We do need to have dinner, though… and I’m going to make sure you get plenty to drink~ I can’t have you leaving that diaper dry tomorrow~”
Rainbow shuddered; this was barely even the beginning. She had a long way to go before this would finally be over.
Rainbow Dash's Diaper Desperation
That night, Rainbow had enjoyed a nice, albeit very teasing and domination-filled dinner with Twilight… all while the alicorn made sure that the pegasus ate and drank far more than what seemed necessary. Afterwards, Twilight had wanted to just relax for a while, though that relaxation ended up involving Rainbow Dash being a hoofrest yet again. At least she wasn’t desperate this time… though, the boredom of acting as a piece of furniture almost made her wish she was holding her bladder or bowels, just so that, at least, something was happening.
Though, when she had that thought… she couldn’t help but notice that she’d felt the slightest little pang of desire. Almost like she’d enjoyed it… and she wanted more. She quickly shook off those feelings; that was an insane way to be feeling about wearing and using a diaper, of all things. But even as she tried to sit and think about something else, her eyes kept going to the satisfied, dominant expression on Twilight Sparkle’s face… and it was beginning to make Rainbow Dash feel a way she hadn’t felt before. The humiliation and shame were horrible and painful, but at the same time, her feelings about it weren’t entirely negative.
Well… it was still mostly negative. Anytime Rainbow’s blush faded, it quickly came back in full force, either because she’d remembered what she’d done earlier, or because Twilight had reminded her. “You look so adorable in this photo~” the alicorn would remark over and over, in slightly different ways, even letting Rainbow Dash take a look at her own figure in the soiled diaper. The pegasus was quick to try to convince her not to take any more, but Twilight almost seemed like she was ready to fill a photo album with these embarrassing photos.
Eventually… “Alright, Dashie - it’s starting to get late.” Twilight had resorted to only calling Rainbow Dash by embarrassing pet names at this point; of course, Dashie was her favorite, a term that made the pegasus feel like she was getting smaller every time she heard it. “I think we should head to sleep.”
“Yeah… where am I going to sleep? You aren’t going to tie me to my bed or anything, are you?”
Twilight chuckled. “Don’t worry, Dashie - I’ll make sure you’re comfortable~ Very comfortable~”
“That, um, that wasn’t a no…”
“It sure wasn’t~ Come on~”
—--------------------------------
Rather than letting Rainbow Dash sleep in one of the many spare bedrooms included in the magnificent, sprawling castle, Twilight led the diapered pony into the alicorn’s own bedroom. “I’m not sleeping on the floor, right?” Rainbow questioned.
“Stop being so worried - it’s not going to be that bad~ And besides… we’re not going to sleep right away anyways~” The bedroom door slammed shut, a padlock appearing on it. Immediately after, Rainbow Dash felt magical rope wrap around her body in an intricate, shibari-like manner, binding all of her hooves together, bending her knees, spreading her thighs, even the chains on her wings being removed just so the ropes could more elegantly tie them down. Only her head was spared; the rest of her body was tied intricately to a wooden chair, seated on it with back hooves spread and front hooves tied behind her. The alicorn soon produced, from a drawer in her desk… a purple wand vibrator, with a large ball at the top and a more curved handle to hold. “I’m sure you’re getting desperate in more ways than one after all of this, aren’t you, Dashie~?” Twilight snickered. “I hope your bladder isn’t too full right now, because otherwise, you’re going to be having a very rough accident~”
Rainbow’s face went red yet again; admittedly, she had started to feel a little horny… and now, it seemed like that was going to be taken advantage of. She couldn’t help but remember Twilight’s hooves touching her so sensitively. “T-twilight, t-this is…”
“What’s wrong, Rainbow~?” The pony put the vibrator against the diaper, pushing it in, making sure the pegasus could feel it against her slit, though it wasn’t yet turned on. “I have no problem with just letting you watch me pleasure myself… but I doubt that’s what you want~”
Rainbow Dash shuddered at the sensation, the light stimulation; her horniness was now skyrocketing, quickly peaking much faster than it had before. “I-I…” She gulped. “I, um, but… I-I already have to pee a little…” She hesitated to admit such a fact, but at this point, her shame wasn’t enough to stop her. Her legs were already beginning to let out the slightest bit of a quiver.
“Oh, really? That’s just perfect then, isn’t it~?” Twilight smirked. “Hold it in while I play with you, and I’ll let you orgasm. Otherwise… well, I happen to have a spell for putting a stop to that sort of thing~ Trust me, it’s not a pleasant sensation - you’ll be pent up all night~”
“T-that’s horrible!” Rainbow quickly responded, biting her lip in fear. “All night!?”
“That’s right, all night~ I’ll let you decide right now whether or not you want to risk it, but I’m probably not going to give you another chance to do this for a long time~” Twilight put a hoof on the vibrator’s switch. “Well, Dashie~?”
The pegasus heavily considered it for a moment; if she accidentally lost control of her bladder and wet herself while Twilight was pleasuring her, it would be beyond embarrassing… but at the same time, the sensation of the wand pushed against her diaper was surging her desire for the pony to press that button so badly, she couldn’t help herself. “Ok, do it!”
“That’s what I expected~” The lights in the room went dim; Twilight flicked the switch, and immediately, the vibrator did as expected, beginning to vibrate. The diaper’s material was thick and absorbent, but not enough to stop the pleasurable sensation from getting through; Rainbow immediately felt a moan coming. She tried to stifle it, but she couldn’t help but let it out, much to her embarrassment and Twilight’s amusement.
The pegasus began to squirm, left and right, her hind hooves and front hooves all shivering from the sensation, her eyes going up as she let out more cute, small, high-pitched moans from her enjoyment; Twilight was eating it all up, one of the alicorn’s own purple hooves soon making its way to her own clit so she could pleasure herself as well. However, although Rainbow Dash would’ve liked to just enjoy the sensation to its fullest, she had another problem to contend with.
With her legs spread so far apart, and all that stimulation right on her crotch, her bladder was beginning to ache far worse than she’d expected. Her cheeks grew hot and scarlet as she dug her teeth into her lip; she couldn’t tell which one was coming, whether she was about to orgasm or piss herself. The sensations were just too similar in that moment, and to make things even worse, Twilight turned the vibrator up, causing it to make far more of a devastating impact on the pegasus’ will and ability to hold back.
“T-T-T-Twilight!!” She moaned out; she couldn’t think of anything else to say. Her legs were now shaking like she was in an earthquake, or like she’d just stepped off a boat. She had to close her eyes to focus on not pissing herself, but the very action of holding that back held her orgasm back as well, and both of those desires of her body were now fighting for control, fighting to be let free. The sensual, indescribable pleasure born from Rainbow’s lust along with the aching, pounding feeling of her bladder trying to release its contents created a storm of emotion and sensation in her body. “Urghh… ahhh~!!”
Twilight held the vibrator in place with magic, even pushing it deeper, pressing it harder. She stepped up onto the chair with her two front hooves, one on each side of the pegasus, encapsulating her body, whispering in her ear. “Come on, let it out - it won’t be that bad~ You’re going to have to piss eventually anyways~” Twilight’s words were sultry and smooth; in her mixed-up, dizzy state, they almost made Rainbow let her guard down entirely. “Come on, it won’t be that bad if you can’t finish - I know I’ll enjoy it that way, at least~ I’m sure it would be so cute to see you pouting about me denying your orgasm - squirming in your chair from the discomfort of being right on the verge, but never being able to release~” She chuckled, tickling Rainbow’s ear with her warm breath.
“Twilight… nhnn… i-it’s too much, I-I can’t hold it in!”
“Then don’t~” Twilight pulled herself up; she kneeled on each side of the chair and hugged Rainbow Dash, putting the pegasus’ head into her fluffy chest, embracing the diapered pony in a warm, comfortable, guard-dropping sensation, while pushing the vibrator in a bit further. “Just let it go~ Though, I don’t know if you mean your orgasm, or your bladder, at this point~ I guess we’ll be finding out soon~”
“Twilight… ahhh~!” Rainbow Dash let out a particularly loud, long, and intense moan; her whole body continued to shake as the familiar sound of her urine trickling against the diaper filled the air, quickly followed by her body being racked by an incredible orgasm…
…or, at least, it would’ve been, had Twilight not acted so quickly.
The alicorn stepped off of the chair, smiling sinisterly, her horn glowing as Rainbow continued to pee herself. She squirmed and shook, her face one of discomfort and dissatisfaction. “I-I’m so close… urgh… w-why won’t it happen!?” Rainbow complained.
“Sorry, Dashie, but I told you what was going to happen if you peed yourself~ No finishing for poor Dashie today~” Twilight’s magic was a complicated thing; this spell affected Rainbow’s insides, not making anything physical, rather just wrapping around her nerves in a way that completely prevented her from finishing her orgasm. Although, the sensation of being right on the edge remained; the pegasus kept squirming, trying to let it out, but her body just wouldn’t do it… until finally, the feeling subsided, leaving her with nothing but a vague ache from the unfinished task. As well as the warm and wet sensation of her full diaper, of course…
…and, as if things weren’t bad enough, before she knew it, she was feeling pressure in her backside… and the yellow diaper soon turned to a newer, much darker shade, as Rainbow groaned in dismay. “Oh Celestia…” she whimpered, turning her head away and keeping her eyes shut tight out of humiliation.
“Hmm… I think that spell still has a few kinks to work out. I didn’t realize it would affect your bowels so much~” Twilight chuckled, her horn glowing, the ropes removing themselves. Rainbow’s feeling of being right on the edge had somewhat subsided, but she was still left extremely horny and needy.
“Twilight…” She gulped; she couldn’t believe the words that were about to come out of her mouth. “P-please let me finish… I-I’m so close…”
“Sorry, Dashie, but that’s not happening~ As long as I’m still punishing you, I’ll make the decisions on what you are and aren’t allowed to do~ Maybe I’ll let you try again in a few days~” She smirked. “As for myself, well…” She grabbed Rainbow Dash’s leash and pulled her to the ground; the pegasus landed on her hooves, not necessarily falling. Twilight immediately put a hoof on Rainbow’s head and pushed her down again, as she had before… but this time, she moved her other hoof to her slit, stimulating and touching herself. In only seconds, she orgasmed, her whole body shivering and shaking; Rainbow could feel every little quiver through her hoof, planted so firmly on the pegasus’ head. The diapered mare couldn’t help but watch as Twilight covered her own hoof in marecum, huffing and panting afterward, showing that she’d clearly enjoyed herself quite a lot. “Oh, that was amazing~ It felt so good~ I’ve been holding that in all day - playing with you makes me so horny~” She giggled.
“Twilight…” Rainbow blushed; honestly, she’d enjoyed that show more than she’d imagined, being practically forced to watch due to her face’s position… but more than anything, it rubbed in that she still couldn’t orgasm herself. She sneakily moved a hoof to her own slit and rubbed her own clit, and even though it stimulated her at first, she could feel the blockage from Twilight’s spell; she could pleasure herself all she wanted, but there would be nothing but disappointment waiting at the end of it.
“Aww~ I was right - you are adorable like this~ I usually don’t like to see my friends upset, but when I’m the one in control, it just makes you so cute~” Twilight nuzzled her head against Rainbow’s in a cuddly, loving way. “Come on - into the bathroom. Let’s clean you up one more time… and then, we’ll go to sleep~”
Rainbow sighed; this was apparently going to happen a lot. “Yes, Twilight…” she said, resigned…
…though, her time with Twilight that night wasn’t going to be nearly as bad as she was expecting, considering what’d happened the previous day.

Never Forgotten
With a newly clean, fresh, and slightly warm diaper on, Rainbow returned to Twilight’s room, led by the leash… though, not without a quick stop at the kitchen for Rainbow Dash to drink plenty of water to fill her bladder back up.
The lights were already dim, but they now faded to pitch black. “I know I already asked earlier, but really, where am I sleeping?” Rainbow asked; at this point, although her shame still weighed heavily on her, traveling through her nerves and limbs like an electric current, she’d begun to accept the situation… and still, even in this constant cycle of humiliation and torment, she trusted and loved her friend.
“Oh, I never actually told you, did I?” Twilight pulled the covers back and got in bed; she patted the spot next to her. “Right here - with me~”
Rainbow’s face was covered in a light pink; the blush was for a different reason this time, however. “You want me to sleep with you?” She asked, a bit surprised.
“Of course - why not? It gets cold in here during the winter~” Her magic grasped Rainbow Dash, levitating her. The chain around her wings (which had been put back once Twilight was done with the chair) dissipated as she was placed into the bed next to the alicorn.
“Woah… you’re letting me free?” Rainbow asked, moving and flapping her wings a little as Twilight put the covers over them.
“Of course not~” Twilight reached out and hugged Rainbow Dash, pulling the pegasus into a tight, warm, fuzzy, comforting embrace and cuddle. “I’m going to make sure you can’t get out of here~ Though, I padlocked the doors and windows, too~” She chuckled.
“I’d think you’re insane, if I didn’t know better…” Rainbow responded, though she immediately wondered to herself whether or not she actually did know better.
“I’d be surprised if this is the first time you’re considering that possibility.” The alicorn chuckled; suddenly, Rainbow began to move downwards a bit, due to her magic. “I do want to cuddle you… but, well, if you end up needing to use that diaper, I don’t want to feel it~” She made sure that the diaper was past her own body, and positioned Rainbow Dash so that her head was against Twilight’s chest, like earlier. The princess embraced Rainbow’s head, pulling it in, making sure it was tight and secure between her furred legs and fuzzy chest, safe and comfortable, but also trapped. “There we go - that should work~”
Rainbow was pretty much under the blanket entirely at this point, but she didn’t complain - it was especially warm, as well as nice and dark. Plus, at least this way, she could hide her blush. “What if…” Rainbow started to speak; she was going to ask what to do if she had to use the bathroom, but at this point, that question seemed entirely pointless. She already knew the answer: the diaper, of course. She was almost getting used to it at this point.
“Alright, I’m going to sleep. Goodnight, Dashie~ Oh, and if you need to use the bathroom, wake me up first - I want to watch~”
“There’s no way I’m going to do that,” Rainbow quickly responded. “I mean, I’m not going to wet myself in your bed. That’d be way too embarrassing. And even if I was, I wouldn’t tell you first.”
“Not even if I removed my spell stopping you from finishing~?”
Rainbow pouted and sighed. “Well… maybe then I would…”
“Then if you’re a good pony and you tell me when you’re about to wet yourself, I’ll consider it~ And I won’t be able to change your diaper if I don’t know about it anyways~”
“Mmm… alright, fine…” Rainbow conceded; she was embarrassed to be giving in so easily. She felt like Twilight owned her.
“Perfect. Goodnight, Rainbow~”
“Goodnight.”
Twilight didn’t struggle too much with drifting off; she was tired enough from the day’s activities. Rainbow Dash should’ve been similarly tired, but she wasn’t feeling that way - the constant pressure of Twilight’s body wrapped around her was making it difficult to clear her mind. She could hear the slow, soothing heartbeat in the princess’ chest; it was distracting, but at the same time, like a lullaby, it was slowly lulling her into relaxation.
And of course, it was at that point where she started feeling the need to pee.
Already, she was half asleep; it wasn’t a good position to be in. The exhaustion of all the humiliation and shame she’d been subject to had weakened her mind and body, lowering her defenses significantly. Her hooves began to let out the lightest little shiver; she quickly pressed her thighs together, trying to wake herself out of her half-slumber, but her brain struggled to come back so quickly. The heartbeat, the cuddle, everything in this situation had tricked her mind into thinking she was in an entirely safe situation, and it was difficult to deny herself the sleep her body so desperately wanted, even as she also had the need to use the bathroom.
Rainbow reached down and pressed against her diaper; she could feel it, her bladder slowly filling as her body processed the great amount of water the alicorn had made her drink. Soon, it filled to the top; it began to ache, feeling like a water balloon that was being filled far too much. She pressed her thighs together as hard as she could, rubbed them against each other, put both of her hooves against her crotch and smushed them between her thighs, applying as much pressure as she could manage. Still, her eyes remained half-closed, her brain working slowly, too slowly, not recognizing the threat.
The pegasus squirmed, trying to keep the movements small to not wake Twilight; the last thing that she wanted was to piss herself for the third time in one day. She’d never recover from that embarrassment. “Ngh…” She gritted her teeth and focused all of her mind on her bladder, on holding it in; her squirms became more intense, her whole body now letting out intermittent shivers. She could feel it now, the urine slowly getting closer to releasing itself; she had to keep consciously pulling it back, going against her natural instinct to let it free. It was so much harder than it had been before. It was like Twilight had managed to train the pegasus to use the diaper - it didn’t feel nearly as wrong or off anymore, but it was still so humiliating.
Twilight’s grip suddenly increased; still completely asleep, the alicorn suddenly pulled Rainbow Dash up, back into a normal cuddle, ignoring the diaper completely. Rainbow’s eyes widened; she tried not to make any sounds. The princess was clearly deep in sleep; her eyes were fully shut, her mouth only moving ever so slightly with the little breaths she was taking. It was cute… and it only lowered Rainbow’s guard even further. The purple pony’s grip increased; she pulled the pegasus closer and tighter, wrapping her front hooves around her tightly and squeezing her, pulling her head closer as well and nuzzling it softly, her warm breath gently spreading across the blue pony’s fur.
Twilight managed to pin Dash’s front hooves to her side, holding them so tight she might as well have bound them with a rope. Even worse, her back legs, instead of simply wrapping around Rainbow or whatever else, slid between Rainbow’s legs, pulling them apart, making it so she couldn’t easily rub her thighs together anymore. That was what really made it the most difficult - in her sleep, the alicorn had managed to put Rainbow’s body into the perfect position to make her piss herself. It was like she’d just pulled a dam out of place.
“Twilight…” Rainbow murmured in worry, not thinking about her words. She tilted her head back and focused as hard as she could, but her bladder felt like a glass of water on the tip of a table, slowly getting nearer and nearer to the edge, where it would soon fall and spill all over, and she couldn’t reach out and grab it in time.
And soon enough, the inevitable happened - she reached the point of no return. It began with the smallest little leak, a small little spurt of yellow trickling from her slit into the diaper, almost entirely soundless. And, like a small hole in the hull, it was enough to sink the whole ship.
Rainbow’s body shook; she tried to hold back one last time, but her bladder had made its decision to empty its contents. Rainbow couldn’t help but sigh as urine streamed from her slit, quickly filling the diaper like a hose, the sound of liquid hitting the slowly dampening material being loud, even as it was muffled by the blankets. The warmth felt weirdly good to Rainbow Dash’s half-conscious self; the dampness was far more uncomfortable, but her body had grown used to this sensation. It didn’t wake her up entirely, not like it should’ve.
“Mmnnmm…” Twilight rustled and squirmed; slowly, she opened her eyes, her grip loosening itself as she awoke. “Dashie? What’s going on?” She asked, rubbing her face with a hoof. She grabbed the blankets, turning her head towards them and slowly raising them to see the source of the noise…
“W-wait, Twilight, d-don’t look!” Rainbow quickly said, trying to stop the princess… but it was too late. Twilight’s horn glowed, shining light onto the scene below, of Rainbow Dash’s diaper turning more and more yellow as it was filled.
“Well, well~ Did some poor pony have another accident~?” She grinned. “Why didn’t you wake me up sooner, Rainbow Dash? I would’ve loved to hold you while you struggled~”
“Well… you sort of did already…” the pegasus murmured, pulling her chin down and looking at the pillow they were sharing.
“Did I? Oh, I guess I wasn’t holding you in this position when I went to sleep. Sorry, I’m a bit of a sleep cuddler~” She chuckled. “Oh, you’re so adorable~ I always love seeing that nervous little blush on you~”
“Twilight…” The pegasus whined like a child who was getting embarrassed in front of their friends.
“Come on, let’s get you changed, and then we can finally go to sleep. You should rest up - I still have more ideas I want to try with you tomorrow~” Her horn glowed; the diaper was soon magically replaced. “I’ll clean you off in the morning.”
“Isn’t wetting myself three times enough? This feels excessive…” the pegasus complained.
“No way - I’m having way too much fun to stop now~” Twilight gripped Rainbow Dash yet again, pulling her into another full-body cuddle. “Goodnight, Dashie~ Try not to have two accidents in one night, ok? That would be extremely embarrassing~”
“Mmm… g-goodnight, Twilight…”
And soon, both of them drifted to sleep, in each other’s hooves…
…and following that, the week continued.
Every day, Twilight had new ideas for what Rainbow Dash was going to be doing, each one getting more and more humiliating, resulting in the pegasus messing or wetting herself two to three times daily. And of course, many pictures were taken, all featuring Rainbow Dash in a number of embarrassing, humiliating positions, treating her like a fashion model… or really, more like a toy, considering Twilight just used her magic to move the pegasus around.
The week was long and difficult for Rainbow Dash, but it felt far too short for Twilight; she had more fun than she could’ve expected. And slowly, the pegasus couldn’t help but realize that, at some points, she was enjoying herself a bit too… and it didn’t help that Twilight constantly pleasured her at entirely random times, conditioning Rainbow to almost like being in the diaper. Still, it wasn’t enough to take the pegasus so far that she developed a new kink… but by the end, she was almost yearning for more.
Finally, the last day arrived; the fun had all started on one Saturday afternoon, and now, the clock had struck that same time. “Oh, finally! Please tell me it’s really over this time,” Rainbow Dash pleaded, her diaper wet and full.
“Alright, I did say I was only going to do a week, so we can stop here. I also just ran out of diapers, so I couldn’t keep going, even if I wanted to - you’re lucky, Dashie~” The diaper floated off; a magic force cleaned Rainbow’s backside in seconds.
“Wait, you could clean me with your magic the whole time!?” Rainbow looked at her entirely spotless backside in shock. “You didn’t have to do it by hoof at all!”
“That’s right~” Twilight responded, snickering. “I just wanted to clean you myself. It was more fun that way~” The diaper floated over to a trash can, accompanying a slew of other filled diapers, the amount somewhere in the high 10s. “And I know you liked that part, too~”
“Mmm…” Rainbow looked to the side, with one last embarrassed blush. “Can I go now?”
“Did you learn your lesson?” Twilight responded, looking Rainbow in the eyes. “I don’t want to have to do this to you again~ Or, I should say, you don’t want me to have to do this to you again… because I will do it, and I will enjoy it~”
“I swear I learned my lesson! From now on, I won’t do pranks that often. I’ll make sure to space them out so they don’t become a nuisance to other ponies. I really mean it - I don’t think I could ever forget this, not after all of that.”
“Good!” Twilight grinned and patted Rainbow on the head. “Alright, you’re free to go! But, well…” Twilight held Rainbow’s chin and pulled her close; the alicorn whispered, “If you ever want to be punished again, I’ll make sure I have plenty of diapers~” Twilight planted a light kiss on Rainbow’s cheek.
Immediately, the pegasus’ face went bright red; she pulled away, her heart beating rapidly. “No chance, I would never do something like that willingly!” Even as she said those words, she wasn’t entirely sure if they were true; she had some mixed feelings about this. It was hard to pinpoint exactly why. Was it the domination from her friend, the sadistic glee Twilight clearly felt, the humiliation, being taken care of so tenderly… she didn’t know.
“Hmm… If you say so~” Twilight said, her voice making it clear that she didn’t believe the pegasus. “I’ll see you soon, Rainbow Dash~”
The pegasus bit her lip, her blush glowing. “Yeah… I-I’ll see you soon, Twilight.” And with that, she was gone.
Twilight watched the pegasus fly back up to Cloudsdale; it had been fun, but all good things must come to an end, of course. She pulled out the many pictures she’d taken, already reminiscing… and then, she looked up to a corner of the library… and her horn glowed. There was a waver of magic, and then, a camera-like structure appeared. “She has no idea~” Twilight said to herself, smiling sadistically. “I shouldn’t have worried - of course Dashie wouldn’t notice the secret cameras I have in each room. I have a whole lot more footage to enjoy… and a lot of planning to do for next time~”
This certainly wasn’t over yet; Twilight already had ideas, and Rainbow Dash was the perfect subject of her bullying. Many lessons were yet to be taught.
