The classroom was sufficiently decorated with educational decor. Charts of math tables and storybook illustrations dotted the pale green walls with the occasional poster about being prepared for class or how to tell time placed in between. A large chalkboard dominated the north facing wall, designating it as the front of the room. Single hung windows provided a fair bit of natural light into the room, brightening up the already vibrant learning space.
Rows of school desks took up most of the room with enough to comfortably seat at least twelve students. They were all neatly organized into rows and columns for optimum paper passing efficiency. Across the room sat a teacher’s desk, a sturdy, wooden thing with plenty of drawers to store pencils, papers and test packets. In one of the back corners of the room was an activity area with shelves of supplies and a round table to gather at. A small kitchenette, consisting of a sink, fridge, counter space, and cupboards sat close by as well. The room was dead quiet this Saturday afternoon.
Macintosh and Cheerliee stood in the center of the room to take it all in. They both wore thick white diapers as large as pillows around their waists, the perfect outfit for what was to come. By the spontaneous and giddy request from Cheerliee, Macintosh had come to visit the school on an off day to partake in, what Cheerliee like to call, “foalish school games”. And he was quick to accept. An afternoon with the cute teacher, it was hardly something he could pass up!
Cheerilee diverted Big Mac’s attention to the cluster of desks. “Please have a seat at any desk you like,” she said while pointing with her hoof, “I have a few things I need to get out of my desk.”
Big Macintosh nodded and scurried off to a nearby desk. He opted for the front row, hardly wanting to seem like a trouble student to his temporary teacher. The small wooden seat took some getting use to, but he found the plushness of his diaper aided in its comfort. The small desk, built for school aged foals, was lower to the ground than what Macintosh was used to, forcing him to slouch forward. He felt silly sitting at such a small desk. He felt like the new kid on his first day of school. These feelings were only amplified by the bulging diaper that crinkled with each tiny shift he made trying to cope with the child sized seat. The diaper made him feel like he should be in nursery school instead.
By the time he looked up, Cheerilee was already walking up to his desk with supplies in hand. With a diaper just as thick as his, the purple pony coped with the bulk by widening her gait into a toddlerish waddle. In front of him she dropped a stapled packet of paper as well as a freshly sharpened pencil. She wore a very happy smile as she spoke. This was something she had been looking forward to for quite awhile. “I want you to take a little test for me. This one I had drawn up special for you.” She took her time explaining, enjoying the scene she was playing out with the overgrown student, “it won’t be anything difficult. My students would have no trouble answering these questions.” Big Macintosh gave the test a quick glance over as Cheerliee waddled back to her desk. “I’ll be here when you’re done,” she added as she opened a book and leaned back in her seat. That left Macintosh with the task in hand, diaper or not, it seemed that Cheerliee had her plans.
Macintosh gave the test packet another look over. On the surface it seemed pretty standard. The first page started a long list of numbered questions with a big space at the top for the test taker’s name. Without reading anything else, he went ahead and filled his name in with a pencil.
The cute little test Cheerilee had written up for him was in no way difficult, hardly going beyond a second grader skill level. Most of it consisted of easy questions ranging from science to history. Easy facts that any kid could recall from their school careers.
Big Macintosh was a bit older than the children expected to do tests like these, but if he searched the deep recesses of his mind he could recall all he needed. It was tough to forget things like how many sides a triangle had or that a yard was longer than an inch. Most of these questions were rather insulting really. Of course, that might have been the point. He was wearing a diaper after all.
Despite the low skill level of the questions, it still took Macintosh time to read them, fill in the little circle next to the right answer, or to write out his answer. Sometimes he struggled to even figure out how to explain his logic. Stuff like what time the little pictures of clocks read or how many cups were in a gallon were difficult to explain because of how second nature the information was. His adult life never asked to explain anything so simple, it was just universally understood that they just were.
And so, whether he liked it or not, the test took at least an hour to complete. An hour that he didn’t quite know he could withstand. About half way through the stapled packet of papers, his bladder began telling him that it was full. Apparently the tall glass of milk he had during breakfast to wash down a rather hefty meal was catching up to him. He had hoped he could just hold it for now and put it off, but crossing his legs only did so much, especially when the diaper’s bulk kept his thighs slightly apart.
He just needed to let a little bit out. Just enough to relieve the pressure, than he’d be able to focus. He inched his thighs apart and shifted in his tiny seat to find a more comfortable posture to piddle into his diapers. Just a little bit, he was sure to constantly remind himself. He found that leaning forward a bit helped things along. But just a little bit, that’s all he needed and then he’d be able to finish the test.
It started with a little spurt which, after using every ounce of self control, quickly ceased, allowing the little splash of urine to soak into the waiting diaper. That seemed to help a tiny bit. Painful at first, but soon the pain faded away and left behind a slightly relieved bladder. He dared another spurt, garnering another brief wave of relief. He was so focused on his tiny, controlled urination that the test fell to the wayside. Another quick spurt was quickly released, followed by yet another brief wave of relief. He sighed at the successful release. Before long his bladder no longer felt so achingly full. All it took was a little bit of control and he was able to get his focus back.
Suddenly a big fluffy diaper plopped itself onto the corner of his desk, nearly surprising the diapered stallion right out of his seat. He looked up startled to find Cheerilee standing at his side with a knowing smirk. He knew she must have been watching him carefully relieve the pressure in his bladder, but couldn’t quite tell how long she had been watching.
“I’ll change you after you turn in your test,” the purple pony simple said before turning away and returning to her own desk. Her thick diapered rump wagged behind her, catching the eye of the big stallion.
Still dry, Big Macintosh quickly concluded. Even after all this time, Cheerilee’s diaper was still dry! He stole a quick glance between his own legs to find a sizable yellow stain on the front of his diaper, the collective moisture of his numerous controlled spurts into his diaper. So much for ‘a little bit’, Big Macintosh mentally grumbled.
Rather peeved by it all, he returned to the test. It was hard to focus with the dry diaper sitting there like a constant reminder of what was to come. It reminded him of the moist diaper that was between his legs and was sure to hint at the futile attempts he made to avoid soaking his diaper which was, ironically, to wet it a little bit. Or it would have been a little bit if he hadn’t gotten carried away.
Looking down between his legs again confirmed that it was, in fact, not a little bit. Why the sum of all his little spurts had amounted to a rather large spot on his diaper, something resembling a little accident. Nothing to merit a diaper change by any means, but large enough to be noticed. He could have very easily achieved such results by peeing into the diaper without holding back for a few seconds rather than the good ten minutes he had killed carefully relieving pressure.
So why would it matter? Cheeriliee was expecting to change him after the test regardless of how wet it was. So why would it matter how wet or sort of wet his diaper was when he reached that point? He still needed to go anyway.
For the numerinth time that day, Big Mac’s attention turned away from the test and focused back on his diaper. Now he had to willingly wet himself with whatever he was holding back not minutes ago. After stopping and going so many times early, his bladder was more than happy to oblige. He only needed to give the final approval before a powerful stream began spraying into the diaper.
He sat there as casually as one could while diapered and sitting at a children’s school desk, which in reality meant he sat stiffly and unnaturally hunched forward. He could feel the urine trickle all around his crotch as the warmth soaked and swelled every inch of the diaper it touched. He blushed as the urine found its way to his butt, tickling it ever so slightly before swelling up the seat. The pillowy soft seat of the diaper now had the consistency of mush as the gels quickly snatched any amount of urine that had come their way.
When his bladder ran empty, Macintosh could only think to sigh, taking in a steady breath of relief. Finally he was able to focus completely on the test, no longer impeded by the aching strains of his bladder. Filling out the test was a breeze after that. With a relaxed bladder and a relaxed mind, he was able to answer the questions easily once he had the mental energy to commit to it.
By the third completed page, he stole another glance down between his legs. The once tiny spot now evolved into an all encompassing yellow that covered the entirety of his crotch. The material had swollen quite a bit, dwarfing whatever the diaper might have looked like when he put it on. He instantly regretted looking. It just made him more nervous. But at the very least, the only real silver lining he could find in this predicament, was that he had enough brain power to finally finish this blasted test, even if that meant he was to spend it wallowing in the heavy, warm diaper the entire time.
In a flash two more test pages were finished. Or at least it felt like a flash to Macintosh. He had stopped looking up at the clock ages ago, too involved in the test to even pay it mind. It didn’t matter what time it was. What mattered was getting this test finished and turned in.
The seventh, and to Macintosh’s relief, final page at long last was turned to. The end was near! He breezed through the last set of questions without issue. At least, most of them.
Things were fine until he reached the final question. ‘Is Macintosh a big boy? Explain your answer.’ The final question on the test made Big Macintosh’s cheeks flare up a bright red.
He gulped, looked up at Cheerilee with blushing cheeks, and then looked back down at his paper. Thankfully Cheerliee was too involved in her book to really notice the stallion’s sudden discomfort. Was he a big boy? His wet diaper made that question easy to answer. He picked up his pencil and reluctantly answered as truthfully as he could manage.
Big Macintosh is not a big boy, not any more, He wrote in the space provided, He’s not a big boy because he couldn’t hold it and chose to wet his diaper during the test. A big boy would have held it till the end or even asked nicely to use the potty. An idea that came to his mind as he wrote it. He kicked himself for not even considering such a simple solution. He was just so focused on completing his test. Big boy’s don’t wear diapers. He added that last part with a tingling blush in his ears. Surely he wasn’t a big boy anymore.
He closed the packet of paper with a satisfied nod. He was done. After quickly reviewing his test, he stood up from his tiny desk and waddled over to Cheerliee. He was immediately reminded of his soaked diaper as its swollen weight pulled at his waist. The diaper’s happy crinkles were now replaced by hefty, soggy sways as he made his way over to his teacher. Cheerliee was ready for him when he arrived, long since putting down her reading book after hearing the loud sloshing of Macintosh’s diaper draw near.
“A-all done,” the stallion blushed, plopping the stapled packet of papers on the mare’s desk before quickly twisting around to retrieve the diaper off his desk.
“Hold on, eager beaver,” Cheerilee quickly interjected before Macintosh could take a single step away, ”I gotta see how well you did!”
Big Macintosh’s cheeks flared up and slowly turned back around to face his stand-in teacher. Cheerliee meanwhile took her time retrieving a red pen from her desk and scooting her seat up close to the desk in preparation. Macintosh uncomfortably rocked from hoof to hoof. He had no choice but to stand beside the desk as Cheerliee gave his test a thorough review.
Silence fell over the classroom as Cheerliee switched to grading mode. It was a silence almost like the one that hung over the room during the test, but this one had a hint of embarrassing subtext added to it. She uncapped her red pen, retrieved the answer key from a drawer, and positioned Macintosh’s test dead center of her desk.
Standing here, Macintosh was completely exposed with his diaper out in the open for anypony to see. At least during the test he had the desk to hide behind. During the test he could have probably slipped in close to the desk and completely hide his diaper away from any prying eyes. It wouldn't have looked very natural, but he’d be hidden sort of. But now he stood there, hardly daring to move an inch out of fear his diaper would draw more attention to himself. He silently begged Cheerliee to finish her work as fast as possible.
Cheerliee took her sweet time grading the test. It was fun to keep the big diapered stallion in suspense, but she also had her professionalism to uphold. Even if the test didn’t hold any academic weight, she couldn’t even think to rush through it. Beside the open test packet sat the well organized answer key. Of course knowing whether answers were right or wrong was easy to determine without referring to any answer key considering their low skill levels, but for some of the harder ones, she made sure to glance back to the reference material two or three times ‘just to make sure’.
Finally Cheerliee got to the last page, making Big Macintosh tense up. She glanced over his answers while occasionally looking at her answer key to double check his work. Anything to stall and keep the big stallion in wait. During the whole thing she kept the same expression on her face: focused but thoughtful.
Her expression then suddenly changed to an inquisitive smirk and a raised eyebrow. She looked up at Macintosh and her smile grew with a knowing grin. Macintosh felt red flood his face. She was reading his answer for the big boy question, he just knew it. She seemed to like it quite a bit. She didn’t say anything though and simply wrote her final notes and made her final mark on the front page.
“Well I must say Macintosh, I am very proud of you,” Cheerliee smiled, “you passed the test with flying colors!” To further drive her point home, she decorated the test paper with a smiling star sticker. “I can see you’ve been studying! Well done!”
“Th-thank you...Miss Cheerliee...” Macintosh responded with a bashful blush.
“Thank you for answering your questions truthfully,” Cheerliee winked with a smile.
She paused for a moment to keep Macintosh waiting. She enjoyed the sight of the blushing stallion standing in front of her desk like a little child. She could have spent all day staring at that saggy diaper butt, but instead she sighed peacefully and set out to cleaning off her desk. Papers and pencils and little tabletop knick knacks were taken off the desk and redeposited into their designated drawers.
“Alright, hop on up,” Cheerliee said as she gave the wooden surface a tap.
Macintosh was surprised, “wh-what? Why?”
“This desk isn’t just for grading papers,” Cheerliee answered, “it’s also good for changing diapers. And YOURS will be the biggest of them all!”
