In Which Bathroom Denial Leads to a Diaper Trial

Twilight had a problem. She was midway through a test at school and her bladder was full. It wasn't asking anymore, it was telling her that if she didn't get up right now and head straight for the toilet, there would be a puddle.

If she could hold it for a while longer she could try to hold it untill the end of the test, but if she really can't hold it she can ask the teacher if she can go to the bathroom and come back to the test.

She really can't hold it. She asked the teacher if she could go to the bathroom, but the teacher said no. She'd never had to go this badly before in her life. Well. Except for that one time at the dentist. She desperately held on regardless, bursting at the seams. There would be a damp spot on the chair from leakage. Fifteen minutes later, her bladder took over her higher brain functions. She found herself standing up and walking with purpose towards the bathroom, but the teacher stoped her.

"I'm sorry but you'll have to take a zero for this test."

With the shock of that revelation, her bladder could take no more. Her tail lifted reflexively and the urine stream splattered on the floor, clearly audible in the silent auditorium She was mortified.

"I guess you really couldn't hold it. Alright, take this hall pass and go to the nurse's office."

Twilight was still peeing in fits and starts as she tried to shuffle her way out of the room without getting it on anypony. The puddle itself was impressive in size, and there was a cry of disgust as another student noticed that the puddle extended all the way underneath the other pony's desk and she'd put her hoof in it.

Twilight almost chickened out. She didn't want to see the nurse, but as she was hesitating in front of the door, the nurse opened the door.

"What's wrong? Are you feeling unwell?"

"I, um, had an accident." Twilight responded before clarifying, "Of the bathroom variety."

"It's alright dear. I'm going to take care of you. Just go ahead and wash yourself off in that shower."

Even though not much of the urine had splashed on her, Twilight did as she was told.

"I'm sorry that happened to you. It's not your fault. Accidents happen to everypony at one time or another. Are you feeling better now?"

"Yes, thank you."

The nurse opened a drawer and handed Twilight a diaper.

"Wear this next time you have a test." The nurse instructed

Twilight balked.

"I'm sorry," Said Twilight, "but I can't wear a diaper. Everypony will see!"

"It's enchanted, dear," The nurse explained, "For modesty. When you put it on it will become invisible until you take it off."

After thinking it over, she took the diaper. At the very least the invisibility enchantment would be interesting for her to look at when she got home.

Twilight placed the diaper in her book bags, but she realized after a moment that the diaper would be seen the moment she opened her bags in class. The only way to properly hide it, she reasoned, would be to put it on.

Quickly ducking into a bathroom stall she opened the diaper and carefully taped it up. Sure enough, when the last tape was secured, it vanished, though she could still feel it was there.

In the next class she appreciated the small amount of extra padding the diaper gave her on the hard seat. What she didn't appreciate was the fact her bladder was filling alarmingly fast. In her haste to hide the diaper she had neglected to pee, and after her earlier accident it seemed like her kidneys were stuck in overdrive. She wasn't sure if she could make it to the end of class.

She considered asking the teacher for a break, but she was worried about getting into trouble. She decided to try and hold it a little longer.

She started to squirm in her seat. She crossed and uncrossed her hind legs, but it was no use. The pressure was too much. She slowly raised her hoof.

"Yes what is it?" Asked the teacher

"Can I go to the bathroom?"

"No. There's thirty minutes left in class, you can wait."

Twilight's bladder couldn't take it anymore. She wet her diaper in front of the whole class. She was immensely grateful that she'd decided to put it on, since it was the only thing hiding her shameful accident.

She'd have to ask the nurse for another diaper, but her dignity was maintained.

The nurse was surprised to see her again so soon.

"What's wrong dear? Did you have another accident?"

"Yes, I, um, wet my diaper."

"It's alright poor thing. Just come to me whenever you need a change."

On the way Twilight felt a familiar twinge in her bladder. She knew she wouldn't be able to make it home without wetting her diaper. She wished she could just go to the bathroom like a regular pony, but it seemed her bladder had other ideas these days.

She thought about asking her mother Velvet if she could run behind a bush, but she gave up on that idea when she realized that taking off her diaper would make it visible again.

"Twiliy do you need the bathroom?" Velvet noticed her daughter's awkward walk and pained expression.

"Um," Twilight thought about her answer, "Yes."

"How bad?" Asked Velvet, "Do you think you can make it home?"

The sharp pain in Twilight's bladder told her that she most certainly could not.

"It's pretty bad, but I can hold it until we get home." She lied.

Her bladder couldn't even wait until her deception was over before it began to release. A jet of hot urine was thirstily sucked up by the padding, but her bladder still ached.

While she was walking she couldn't get a continuous flow started. Each step leaked out a little gush, but her bladder screamed for a proper release, her diaper getting heavier with each step.

When they finally got to the house and Velvet stopped to find her keys, Twilight nearly melted in relief. As soon as she stopped moving her legs her bladder took care of the rest, dousing her damp padding with a desperate torrent of hot liquid.

"Are you alright Twily?" Asked Velvet.

Twilight realized that in her moment of release she had closed her eyes and she was letting out a soft moan. Her face flushed red.

"Er, yeah!" She replied, "I just really have to pee."

With that, Twilight took off at a gallop for the nearest bathroom. Velvet shook her head, expecting to see the trail of shame her supposedly fully potty trained daughter had left behind. Honestly she had half a mind to put her back in training panties sometimes. Velvet was relieved when the floor looked dry. Maybe her little Twilight was finally learning.

Despite the hosing she'd giver her diaper on the front porch, and the dribbles she'd lost in her run to the toilet, Twilight's bladder still wasn't fully empty. Her invisible diaper sagged between her hind legs and forced them slightly apart. She considered taking the diaper off and finishing in the toilet, but she was curious now, to see how much the diaper could hold, and thus how protected she was if she got into a situation where she needed to empty her whole bladder.

She relaxed and allowed the flow to start again, rewetting the already soaked padding. When her bladder was nearly empty she tensed her muscles to push the last little bit out, and then she felt a trickle of urine run down her leg.

Sighing, she felt for the tapes on the invisible diaper, and as she undid the first one, it reappeared. It fell to the floor with a splat, and she could see the entire inside portion was saturated and stained yellow. It was hard to believe that much pee had been inside her a short while ago.

She sat for a moment pondering how she was going to hide this thing.

"Are you alright in there Twily?" Her mother asked

"I'm fine mom, I'm just going to..." Twilight noticed her flanks and nethers were all saturated with urine, "I'm going to have a shower."

Velvet rolled her eyes. It seemed that she'd been too optimistic in thinking maybe Twily's little accidents were a thing of the past. Still, she'd told Velvet she needed to go with enough time to get to the bathroom this time, so that was an improvement at least. So Velvet thought.

In the shower Twilight had some time to plan her next action. She didn't know how to make the diaper go invisible again, or if it was even possible without casting some advanced magic that was beyond her skill level. She could use a stasis spell to stop it from smelling or leaking, and shove it back in her bag which she hadn't had the chance to throw off in her rush to get into the bathroom. The problem was that it had swollen to many times it's original size.

Twilight felt some slightly cooler water run down her leg in the hot shower and realized she'd started to pee a little without even realizing. She took a moment to tell her bladder that despite what had happened earlier she was still in command here and emptying without her permission was not acceptable.

She winced at the feeling of cutting off the flow with her tired holding muscles, and, after a few seconds she let go again, but on purpose this time. The flow only lasted a couple seconds but she felt much better afterwards.

Thinking it over, she decided the best way to smuggle the diaper out of the bathroom was to take her books out of her bag and stack them on the bench next to the toilet as if she had been reading them, leaving room to fit the swollen and, under the effects of her stasis spell, now completely rigid mass of urine and polymer.

When she had a chance, she pushed the diaper to the bottom of the outdoor trash can and hoped it wouldn't be discovered before trash pickup.

That night Twilight had a vivid dream in which she was taking a test and had to go to the bathroom. She tried to hold it, but eventually she was forced to give in and wet her diaper. She woke up in a cold sweat, realizing that she wouldn't feel safe taking a test without protection.

She was starting to fall back asleep when she realized that the dampness wasn't all sweat. She frantically felt the sheets with her hooves and sure enough, they were soaked. She had wet the bed.

She was mortified. She hadn't wet the bed since she was a little filly. Well, other than a slight dribble now and then as she rushed for the toilet upon waking. Or when she was reading in bed and forgot that she had to go. She didn't know what to do. The urine was soaked into the mattress, there was no way for her to hide this, not with any of the magic she knew.

Not knowing what else to do, she called out for her mom. She could see the terror in her daughter's eyes, and smell the faint aroma of urine; her heart ached for her poor little Twily who'd found herself in this situation again.

"It's okay Twily. It's not your fault. Accidents happen, there's no way you could have prevented this, alright? You didn't do anything wrong and I'm not mad with you."

She helped her daughter to change the sheets and cast a cleaning spell on the mattress that removed most of the liquid and odor, but it wasn't perfect and she'd still probably need a new mattress.

Twilight was determined not to let this happen again. Velvet may have thought there was nothing she could have done, but Twilight knew better now. She was going to make sure that she was always prepared when her bladder acted up.

In the morning, Twilight made sure to empty her bladder fully before leaving the house, going so far as to use the restroom a second time just to push out the small amount of urine that had been generated during breakfast. She went to the nurse as soon as they arrived at school.

"Here's another diaper, dear. Just in case."

Twilight was grateful. She was glad that she could count on the nurse to help her through these tough times.

She managed to get through the rest of the day without incident, removing the diaper to use the restroom between classes was not an issue since the tapes were reusable. On the way home however, she started to feel a familiar pressure in her bladder. Like last time, she was wearing a diaper so going behind a bush was out of the question.
A few minutes later, her bladder begged for relief. She was determined to make it home this time, and for the most part she was successful. When they stopped on the front porch again her bladder took that as a sign and she released a tiny spurt before she was able to reassert control.
She didn't run once they got into the house, since she didn't want to dampen her padding further. She'd be using it later.

After putting her diaper carefully to the side, Twilight finally released her aching bladder. She was so relieved and happy. She knew that she could rely on her diaper to save her in a time of need, but if she'd wet it on the way home, she'd have nothing to protect her bed.

Next time she'd have to make sure she had a spare diaper with her. She'd need to find some place to hide it. That way she would be prepared for anything.

As she lay back in bed, she felt safe and secure knowing she had a safety net in case her bladder tried any more funny business.

She had another dream that night, this time she was at a birthday party for Moondancer and she had to go to the bathroom so bad, but nopony knew where it was. Every time she tried to hide behind a bush, or go searching for a public toilet she'd somehow end up back at the party. She was crying and begging the other fillies to let her pee, but they just laughed and pointed at the enormous diaper Twilight was wearing. They started chanting 'Potty pants' and the scene started to spin. Her bladder was stretched to comical proportions and she was scared it might burst so she started peeing. The peeing went on and on, but she never felt like her bladder was getting any smaller. If anything it was getting bigger.

Twilight woke with sharp pain in her bladder. Her diaper was mostly dry, but her strength was flagging. Twilight knew, even with her fatigued brain, that there was no way she was going to may it to the bathroom in time. She gave up. She lay back and let her painful bladder drain into the waiting diaper. The relief was total, and as she pushed out the last little bit she fell back into a deep sleep.

When she woke, she couldn't remember any more dreams, but she had wet the diaper again. Not only that, but it had leaked through to her bedsheets.

She was so frustrated and angry. She felt like she was losing control of her body. She knew she needed help, but she was scared, and ashamed.

Velvet found the wet sheets of course, and she was concerned.

"What's wrong Twily? Why are you wetting your bed again?"

Twilight was too embarrassed to tell her the whole truth.

"I don't know mom, it just keeps happening."

Velvet was at her wit's end. It was one thing for her daughter to have occasional little accidents on her way to the toilet, but now she was wetting the bed again too? She'd thought they got past that stage years ago.

She recalled what another parent had told her about a local clinic that specialized in helping ponies with bladder problems. Perhaps she had been in denial before about her daughter's needs, but she knew now that they would have to pay them a visit.

Twilight was hesitant at first, but she knew, even more than Velvet, that she needed help. They made an appointment and went to the clinic that day.

Since Twilight hadn't gone to school in the morning she hadn't had a chance to pick up another diaper from the nurse. She felt exposed. Like she could embarrass herself at any moment without the protection her diaper afforded her.

Halfway there Twilight felt her bladder twinge, and by the time they'd arrived it was a precarious situation.

"Wait here while I check us in." Velvet instructed.

Twilight could see the bathrooms from the chair she was sitting on in the waiting room, but she'd resolved to wait until her mother came back so she wouldn't get lost.

As it turned out, that was a poor decision. The ponies at the clinic were very supportive even after she had ruined a chair in the waiting room. The clinic was a safe place where she could talk about her problems without feeling ashamed. After talking to them Twilight began to feel better.

They helped Twilight to come to terms with the fact that she would need to wear diapers at all times while they figured out how to help her. They weren't a cure, but they would help her though these tough times with her dignity intact. What dignity she had left after peeing herself in front of all her classmates.

Twilight was grateful for the clinic's help. They gave her a pack of diapers to wear during the day, and a pack of much thicker diapers to wear at night.

The next day at school she was more confident. She knew she had the support of the ponies at the clinic no matter what. That whatever tricks her bladder threw her way, she would be protected.

She felt her bladder fill up to an uncomfortable level, and, rather than ask for permission, she let her urine flow into the diaper. It was a little uncomfortable to sit in a damp diaper for the remainder of the lesson, but it was better than embarrassing herself by getting denied the toilet again.
Twilight found after some time that she liked the feeling of the padding wrapping around her flank, how it made her feel safe and secure. She was starting to get used to wetting her diaper, too. She didn't enjoy it, but it was better than having an accident in front of everypony. At home, when she was reading a particularly interesting book she would sometimes wet her diaper on purpose, it was better than putting down the book and dribbling her way to the toilet.

This night she'd made the mistake of neglecting to use the bathroom before going to bed. The house was was cold, and her bed was warm, and her bladder was too uncomfortable for her to get to sleep.

Hissssssssssss...

Twilight sighed in relief. Fortunately her night diapers were thick enough to take three or more wettings before they went soggy, and even more until they risked leaking. She drifted off to sleep enjoying the extra warmth around her flank.

Twilight learned to live with her bladder issues. They would be a part of her life now, but with the help of the clinic, and the diapers, she was able to manage.
