What A Foal

The next day was hard for Thunderlane, despite his embarrassing plight being made easier with the onesie that covered his rump. He had tried it on the second he got home, and was relieved when it was everything it promised to be. No visible trace of the diaper was there, and the poof it normally gave in the back was nonexistent now. He just looked like his old self, and for a few moments of pure bliss, he could pretend he was normal.

But of course, he wasn’t.

The daytime accidents continued, and despite how many times he tried to overcome his anxiety about the toilet, he couldn’t do it. He felt like he was going to have a panic attack every time. So he just went in his diaper. It was so much easier. Enough that it made him wonder for half a second if he even wanted to be potty trained anymore. But he quickly dismissed the thought as soon as it came. Of course he did! He was a stallion, for goodness sake! He had to smack himself in the head for that one.

But things grew stranger still for Thunderlane, as more and more conundrums kept coming up. A few days after he had restocked on diapers, he had woken up one morning to find that he was sucking on his hoof. It had taken him a few seconds to realize this, and once he did, he pulled it out, disgusted with himself. Although there was a part of him that he completely denied existing that said that it was very comforting and he wanted to do it some more.

Despite his wearing his diapers to bed for some time now, he still liked to waddle around in them before he went to sleep. For some reason, he still found it funny, despite everything he had been through with them. That night was no different. He got himself diapered and powdered for bed, and waddled around his room. But as he giggled and laughed, something was different that time. There was a sense of… Curiosity? Innocence? That seemed to fill him. He looked at everything in the room differently. The books weren’t things to be read, they were things to be played with. The trophies and medals that adorned his walls were shiny things he could enjoy looking at. Without realizing what he was doing, he grabbed two hooffuls of books and threw them onto the floor. He started stacking them into a tower, not realizing even once that he was sucking on one hoof as he did so. When it was done, he giggled and clapped his hooves, before he knocked the tower down. Then, satisfied, he crawled into bed. When he woke up the next morning and saw it, he didn’t know what the hell he’d been thinking.

Despite this, he found himself growing more and more fascinated with foalish things. He couldn’t go to the market without staring longingly at toys, and when he saw a foal sucking a pacifier, he couldn’t help the hot stab of jealousy that pierced him. But still, he managed to tamp down the urge for a long time, until that too grew overwhelming. So he made a trip to Las Pegasus about three weeks later, and bought himself blocks, a few plushies, a rattle, a blue blanket that was softer than anything he’d ever felt, a set of stacking rings, some story books, and an adult pacifier. The one thing he didn’t get that surprised Mesma the most was a bottle. However, she thought that one might have been more explainable. As his foalish side was beginning to come to light, he may have subconsciously began to long for somepony to care for him and feed him. She smiled to herself. Well, it wouldn’t matter anytime soon, anyways. She would feed him, and more.

But one of her last steps would most definitely take longer. She would have to be exceedingly patient if she wanted this to work right. So the night after he bought his toys, she came to him. She whispered in his ear the two things she wanted, and then all she had to do was wait.

Over the next few days, things didn’t change as drastically for Thunderlane as the last ones. In fact, aside from the toys and pacifier, nothing really changed. At least, not that he could tell. That is, until one morning, when he woke up feeling unusual, not unlike that first wet morning. He sat up in bed, and his diaper was throughly saturated with urine as usual. But then he saw a wet patch on his bed.

Uh oh… He thought. My diapee leaked.

For a second he was so surprised by the patch on his bed that he didn’t recognize what he had just thought. When he did, he was understandably horrified. But he shook it off as an after effect of the odd dream he had had last night. In it, he had been playing in his diapers, sucking on his pacifier, and speaking very foalishly. But the difference was that he didn’t care. And there was a mare there… Her hair was pink and white, and she smiled at him lovingly, like he was perfect. He had called her Mommy. But that was just a dream. Nothing more than a fantasy. This was real life.

He was about to go and get changed when he realized that he needed the bathroom.

Gotsa pee pee. He thought. But before he could get here, his body reacted for him. His diaper, already leaking, seemed to not absorb any of his accident. It just ended up on the floor and on his hooves. And for a second, he was bewildered. Then, the feeling of being unclean was too much to bear and he found himself crying. He didn’t wail, though he wanted to, he just cried quietly and sniffled as he made his way to the bathroom. He looked at the toilet with smoking rage. Dumb potty! Why’d you hafta be so scary?! And he stripped himself of his leaky diaper. But then, he realized what he had thought. More specifically, the terms he had used in that thought. He was equal parts confused and horrified.

Did I just…?

And he had. But again, he chalked it up to the dream. He berated himself for a few minutes about going potty on the floor (and he had used that term, much to his chagrin), before cleaning up the stain, and then himself. As he put on a fresh diaper, his onesie, and his Wonderbolt Uniform, one thought stuck in his mind.

What is happening to me?
