Hope you guys enjoy what I have so far!

One Little Slip

It was a clear night in Ponyville, but the stars were unseen through the window of Thunderlane. Only the light of the full moon lit his bedroom, and he preferred it that way. For the task he was about to undertake, he preferred to remain unseen. He pushed his bed to one side, and opened the small hatch on the floor. When he was about fifteen he had put it in one day while his parents and little brother were away. Back then he used it for hiding dirty magazines, or other things he didn’t want seen. Now, it served a different purpose entirely. A sound of crackling filled the room as he picked up the plastic covered object in his hand. He ran a hoof over it. His secret shame. His hoof shook as he picked up one of the objects inside. It too was plastic, or at least sounded that way on the outside. But it wasn’t.

In his hand was an adult diaper.

Thunderlane wasn’t really sure how this whole thing started. It was maybe a month or so ago. He had been walking along the street, heading to the market, when he noticed the cake twins in their stroller. Or, more specifically, the diapers they had been wearing. He didn’t look longer than half a second before he carried on. But as he went about the rest of that day, and the following ones, he took more and more notice of diapers. It seemed like every foal in town had been there, looking cozy and snug in their diapers. When he was at the pharmacy to pick up some cough medicine for his little brother, he couldn’t stop himself from going down the diaper aisle and staring at them. For the life of him, he couldn’t fathom why. He had snapped himself out of that daze and continued on. But on that day, that particular day, the seeds of curiosity had implanted themselves in his brain. He found himself seeing them everywhere, and the more he tried to ignore it, the more it seemed to haunt him. It got to the point where he had to stop himself and give it some serious thought, just to try and get to sleep at night.

Why the heck was it fascinating him so much? What was there to know? Foals wore them, and sometimes the elderly, injured, or ponies with incontinence used them. That was it. But that image seemed to stick in his mind. And he started wondering what they were like. He had been toilet trained before he had any memories he could recall, and had had only one or two nighttime accidents as a colt, and they were so far spaced out that his parents had considered them flukes. He didn’t require any protection. There was something about them that seemed so… Comforting? Safe? He wasn’t sure what the right word was. But that was ridiculous! Why would he, of all ponies, be thinking that? It was like an alien thought had invaded his brain. He called himself an idiot for dwelling on it for as long as he had, and went to bed.

But it hadn’t ended there. He had really thought it would, since he gave it some thought. Usually that made any thoughts he had go away, even if it was for a short time. But in this case, he had no such luck. Every day he noticed more, and thought about it more and more. He thought he was going to go crazy with how much it was overwhelming him. The question to him remained though, what on earth was he supposed to do with those thoughts?

Try one on. His mind answered for him.

It was ridiculous. Beyond insanity. He had no need for them, no use for them. That was it. End of story.

But of course, it wasn’t. The urge and desire strengthened with every passing day. Until finally, he caved.

It had been his annual vacation from Wonderbolts, and he had been in Las Pegasus. It was his last night there. After a night in a bar, drunk out of his skull, he had gone to a store nearby, called Forever Foals. He didn’t know how he knew where it was or where to go, but at that point he was too drunk to mind. He grabbed two packs of Large adult diapers, paid for them, stuffed them in his saddle bag, went to his hotel, and passed out. He hadn’t even remembered them or even looked in his bags until he got home the next day.

When he had seen them, he had flushed scarlet with embarrassment. But it wasn’t as bad as he had anticipated. He couldn’t remember doing it, so that was a plus. And he had done so in a town where he wasn’t well known. If he was ever going to do it, he supposed that that had been the best way to go.

Now there was just the question of what to do with them.

Well, you did buy them. Said a voice in his head. Might as well see what all the fuss is about.

He ripped open the plastic, wincing at the loud sound, and looked down. Inside were several white and fluffy diapers. Tentatively, he touched one, then retracted his hoof as if the object had burned him. But they hadn’t. With less trepidation this time, he touched one. It was an odd feeling. Sort of plastic feeling on the front, but still very fluffy. He pulled one out of the pack and opened it up. The inside was very plush. More so than he had expected. It soothed him in an odd, strange way.

Do I dare…?

He looked around the room. The windows were shut and locked, curtains drawn, and his bedroom door was locked. At that point in time, it couldn’t have gotten any more private. He figured it was now or never, and laid down, sliding the open diaper under himself. It was like a pillow, but less fluffy. He taped it up, remembering how to change a diaper from Rumble’s foal days, though it was infinitely harder to do it to himself. Then, he sat up.

The diaper felt nice, a pillowy cushion beneath his bottom and between his legs. There was something so safe about the garment, that it made him feel slightly less exposed. Only slightly, but it was enough. He had to work to get up from his seated position, but when he got on his hooves it felt strange. The bulk between his legs pushed them apart. Not uncomfortably, but it made walking difficult. He didn’t walk so much as waddle, and the crinkling and rustling of the diaper seemed to intensify with every step.

For some reason, waddling around like that made him giggle. He wasn’t sure why he did it, not then, and not when he reflected back on it later. But he had. He waddled around the room. He didn’t say anything, or do much else besides giggle on occasion, but it was enough for him.

It had already been evening when he put it on, and by the time night had come with full moons and sparkling stars, he had decided to go to bed. He had almost taken it off, but he decided that ultimately there was no harm in it. He could wear it a little longer. He had climbed into bed and slept soundly that night.

In the morning that followed, his shame took over again, beat him down for the rest of the day, but that night, he could not help himself from padding up again. And the pattern continued every night after.

Tonight, Thunderlane diapered himself up before bed. He waddled around the room for a little while, giggling. And for maybe half a second, he saw the world around him in a different light. He wasn’t sure how. It was just… different. But like a shooting star, it was gone just as soon. He shrugged it off, and climbed into bed, leaving a window open to let some air in. The summer nights were hot, and he always left it open. Besides, there was no pony who lived nearby or had keys to his home. He was perfectly safe here- something he may have forgotten at his first paranoid trial of his new garments. Satisfied, he easily fell asleep.

Deep in the middle of the night, when the darkness was blackest and the moon was the sole light in the land, a mare flew up to Thunderlane’s home. The window had been left open, just as she had instructed, and she smiled at his obedience. He had been very susceptible to her- that was why she had picked him. She landed, silent as mist hitting the ground, and looked over at the slumbering stallion. His blanket had left his back exposed, and there was no denying the diaper he was wearing. She smiled and nodded. It was working very well. She thought it might be time for step two. She looked over at the clock, and waited until the clock showed it was three AM. That was the time when biorhythms were at their lowest point, meaning that it was when he was least likely to wake. She leaned over him, and in a calm, soothing voice, began to speak.

“Listen to me closely, Thunderlane…”

The stallion never stirred, and she left him about an hour later.
