The Right Moment

Rainbow Dash began to stir under her covers as the morning sunlight came through her bedroom's east window. Greeting the morning with a reluctant groan, she threw the covers off of her. She was never much of a morning pony, but when she stretched, and heard the crinkle sound come from the diaper in between her legs, suddenly the morning didn't seem so bad.

She swung her back legs over and hopped out of bed, her disposable diaper crinkling with her every step. She walked to her dresser and smiled at herself in the mirror. Rainbow Dash the weather pony. Rainbow Dash the daredevil.

Rainbow Dash the adult foal.

She had been like this ever since she could remember. She assumed she had always had a completely normal foalhood, but not too long since she was out of diapers, she wanted right back into them. Of course, this was something she had kept from her parents. Growing fillies were supposed to want to, well, grow up.

Not her.

Her greatest fantasy was to not have a care in the world. She dreamed of asking her parents to put her in diapers, becoming their baby again. She fantasized about being a bedwetter, and her mom and dad having no choice but to make her wear at night. Those fantasies never came to pass, because as much of a daredevil as she had become, she never had the guts to mention any part of this to her parents. She had spent her fillyhood keeping these innermost desires under wraps. So when she had turned 18, moved down to Ponyville and got a job, she finally had the opportunity to indulge.

But she still felt alone.

This had been her secret life for years. None of her closest friends had any idea she did this. Everything having to do with this fetish was confined to her top dresser drawer, which she kept locked at all times. She knew she wasn't alone in this; the store she got her items from served enough with this kink to keep a steady supply. Still, most adult foals kept this side of themselves from all but the very closest and trustworthy of friends.

Rainbow felt that even her five friends didn't quite fit those requirements. All but one.

She was amazed that she had been able to sleep last night, wondering how Applejack was going to react to her sharing this secret with her. The two of them had been seeing each other for just over six months, and Rainbow finally decided that she didn't want there to be any secrets between them. So she had decided that the time had come. Last night she invited Applejack to come up to her house after work this afternoon, because she had something to show her.

After about a minute of standing in front of her mirror, she felt the morning call of nature come to her bladder. Since she only wore for short amount of times, she still had to concentrate a bit to let her mind know that it was okay to go when she had a diaper on. She exhaled and relaxed her nether regions, and a trickle of urine quickly turned into a full stream, trapped by the diaper. The spreading warmth between her legs was euphoric. So far, nothing else had brought her closer to foalhood than that. After about twenty seconds, the stream died down, and the wet feeling slowly faded as it was swallowed by the padding. The warmth remained, and Rainbow jumped back in bed to enjoy the squishy crinkling sounds of the now considerably thicker diaper.

She wiggled around for a few minutes, feeling down there every now and then, waiting for the warmth to fade away, at which time she ripped the tapes off from the sides, and promptly threw the used garment in the trash can. After a quick shower, Rainbow took the trash bag and dropped it off in the closest dumpster on the ground when she left for work.

Work; the one thing she was hoping would help calm her nerves for the day.

Applejack wasn't sure what Rainbow had in store for her up in her house tonight, but she was likely going to find out in a few minutes. Rather than have Rainbow fly her up there like she normally did, she figured she'd surprise her marefriend a little early by getting there before she got home from work. Without some pegassistance, there was really only one way to do that. Coming up to the front door of Golden Oaks Library, she gave a few knocks, and Twilight was there to greet her in a matter of seconds.

“Oh hey, AJ. Balloon's around back. Listen, are you sure you know what you're doing?”

“If I can lasso Rainbow from the top of the thing in midair, I'm sure I can handle flying it. I've flown one in my time, so don't you fret. I'll have it back tomorrow morning, not a scratch on it.”

Twilight gave her a smile, and pointed her around back, where her weather balloon was waiting. It was enchanted, so there was no gases. Just a matter of pulling on the right rope to control altitude and direction. Once Applejack got the thing airborne, she was glad that Rainbow's cloud house wasn't too far away.

Ironically, Rainbow's house of clouds was actually some of the lowest hanging clouds in the sky. As she got closer, Applejack knew to slow down and take things nice and easy. The last thing she wanted of this early surprise was explaining how she damaged a part of her home. So slowly she went, barely tugging on the forward rope, once she got to the right altitude. Over the course of two minutes, she neatly situated the basket just to the right of the front door.

Her parking job complete, Applejack reached into her saddlebag and came out with a glass bottle containing a glowing blue potion, Twilight's other, more frequent favor. She popped the cork and downed the contents in three swallows. With a small burp, she opened the door of the basket and tenderly reached out to test the results of Twilight's cloud-walking potion. Her hoof met firm but poofy resistance, and pushing against it a few times was good enough for her. As she stepped completely out of the basket, she heard the approaching sound of flapping wings.

“Well ain't this a surprise.” Rainbow Dash called out as she made the final approach to her front door. When she touched down, Applejack gave her a smile and a hug.

“Thought I'd surprise you, and now you don't have to carry me up here. So what is it you have to show me?” Applejack asked as she broke the embrace.

“Well, um... Ya see, there's no delicate way to put it.” Rainbow said as she opened up the front door, inviting Applejack into the foyer. She went up the stairs to her bedroom, Applejack on her heels. Opening her door, Rainbow Dash went over to her dresser drawer. Her cheeks had a tint of red in them by now.

She began to twist the dial of a small combination lock on the top drawer. AJ had been in her room many times, and that lock had always been there. She just paid it no mind. So suffice to say, her curiosity was peaked now. Rainbow turned it for the third time, and the tumbler gave way.

“A few days ago, you said you didn't want there to be any secrets between us, so...”

With that, Rainbow lifted the lock, set it on the top of the dresser, and stepped aside. Applejack gave her a curious look, but nevertheless stepped forward. She placed a hoof underneath the drawer, and pulled out towards her, hoping this wasn't some elaborate prank that Rainbow had been planning.

Taking her first look inside, she didn't quite know what to think. There were a dozen diapers, a container of foal powder, and a foal bottle. The diapers looked big, like they were...

...For a grown pony.

Applejack glanced over at Rainbow, who was shaking with nervousness.

“Rainbow, what is this stuff?”

Rainbow swallowed hard, trying to bring the words to her mouth.

“W-well, I just... Just... Like to wear them. It makes me feel like a foal again.”

Applejack glanced back at the contents of the dresser. The front of the diapers had a graphic of a blue sky heavy with clouds. She really didn't know what to say about all this. About ten seconds passed before the silence was broken with Rainbow's hoofsteps as she quickly came towards the dresser.

“Sorry. I'm really sorry, just... Just forget I said anything.” Rainbow stammered, quickly closing the drawer and replacing the lock before making a full-on gallop for her bedroom window.

“Rainbow, wait!”Applejack called, finally snapping out of her stupor. It was too late though. If Rainbow heard her, she wasn't deviating from her flight up and away from her house.

The farmer stood in her marefriend's room for another minute, before she decided to do the rest of her thinking on the ground. She got in the weather balloon, checking to make sure the door was locked, and began her descent from the now-vacant house, wondering what in Equestria had just transpired.
