The first thing the brown-coated pegasus saw was the stars; the vast expanse of blacks, purples, and dark blues with white specks sprinkled throughout.

Sky Scribbles felt like he was laying on his back, but also couldn't deny the feeling of floating in the starry abyss. It was surreal. Yet when he focused the stars above him just a little harder, he saw white walls come into view on the edges of his peripheral, as if it was an incredibly detailed ceiling of a room. When he wriggled his hind legs just a bit, he got a plastic crinkling sound in return, and he gazed down at the thick white disposable diaper that was wrapped around his nether regions and securely taped at his belly. It was absolute bliss, nearly being unable to bring his legs together due to the foalish garment. Sky slowly closed his eyes and was content to float through the sparkling void without a care in the world.

"Ah, there you are. Does my little pony need a change?"

The feminine, commanding voice pulled the pegasus out of his relaxation, and he glanced up, or rather, what he assumed was up, as a dark blue figure, wings spread, slowly descended towards him. His eyes widened as he took in more details of the figure. Majestic wings, slightly longer-than-average horn, moderate cyan eyes, and a crescent moon against a black sky that served as her cutie mark.

Luna, Princess of the Moon and Night. The Guardian of the Dream Realm.

The dark blue alicorn slowly lowered her legs, and gave one last light flap of her wings, before folding them into their resting positions, as if she had just landed on solid ground between the pegasus' back legs. She raised her right forehoof and brought it forward, gently pressing the tip into his diaper.

"Hm, this might last you the rest of the night, my loyal subject, but it may be better to be safe than sorry," Luna stated, as she lightly rubbed the plastic surface of the diaper he was wearing around his waist. "But what is this?" She asked, her gaze falling from his eyes, tracing down his barrel and belly to the somewhat damp diaper, where a visible bump was growing on the front, betraying the stallion's arousal at the Princess' inspection.

The Princess continued her light rubbing on the front of the pegasus' diaper as he started to take deeper breaths. "May as well get this taken care of before getting you changed."

Luna's voice wasn't erotic or seductive, but rather matter-of-factly, as if this was just a normal part of taking care of a fully grown pegasus stallion that was still in diapers. It crinkled with every press of her hoof, and pretty soon, Sky was thrusting lightly up into her hoof that was massaging his erection that was pressing against the damp layers of padding. He risked looking up at her for barely a second, and he saw no judgement, no disdain, just an expectant gaze of a pony waiting for the inevitable.

With a sharp inhale, a strong single thrust upward, and squeezing his eyes shut, the inevitable did indeed arrive, as Sky felt himself release into his wet diaper. Ropes of his seed were added to the crinkling garment, and when it began to die down, Sky opened his eyes, and the field of stars had vanished, and so had the princess of the night. Instead, he found himself in his own bed, in his near pitch black room, with only the dim light of the moon shining through his bedroom window providing the faintest of illumination.

Pulling the sheets off of himself, he swung his back legs around to the side of his bed, and slid down to a standing position on the floor. He quietly trotted over to the window, and saw the town of Ponyville still nearly silent in the middle of the night. He glanced over at his nightstand beside his bed, looking at the clock that was telling him it was barely 2 AM in the morning. He went over to his closet, slowly sliding the door open, and reached back to his belly and pulled the tapes from the front of his diaper, the ripping sounds feeling like they were piercing an otherwise dead silence for the whole house to hear. When the last tape released, the damp diaper fell to the wooden floor, before being scooped up into the pegasus' hooves, wrapped up, and deposited into the trash can in the back corner of the closet. Sky squinted in the dark, finding the container of wet wipes and pulling a couple out, giving his shrinking stallionhood a once-over with them before likewise depositing them into the trash. With a yawn, deciding he was clean enough, Sky slid the closet door closed and sauntered back to his waiting bed. He fell onto it, curled up, and pulled the blanket back over him, hoping that in the morning, his mind wouldn't forget the lucky dream that had just necessitated his late-night clean up...

Canterlot Castle was in a similar manner of near silence, especially around the royal quarters. Every now and then, you could hear the faint cadence of hooves from patrolling guards in the corridors, if one was awake and alert enough to listen.

Awakening from a meditative trance, Princess Luna slowly opened her eyes, and silently surveyed the darkness of her room. She caught a glimpse of herself in the mirror of her dresser, seeing the glow of her horn dimming after she exited the realm of dreams. She got out of her bed, and went over to the door that went out to the balcony. Stepping out into the cool and breezy night, she peered up at the bright moon in the sky among the countless stars. From here, she could see most of the city of Canterlot. Her gaze hovered over the rooftops, traveling to the hills and valleys below, to a small cluster of buildings she almost couldn't make out against the dark of the night. She took a quiet breath, and the slightest of smiles crept onto the princess' face.

"Mm, I believe he may do."

Author's Note

This is the beginning of a story that I've been wanting to do for over a year.

Never thought I'd seriously consider doing an OC x Princess story that's filled with an ageplay kink.

Feedback is appreciated, but I'm looking to update and conclude other in-progress stories before returning to work on this one.

Thank you for reading! More soon-ish!
