D&D 3.5e: Dragon diapering. (Private.)
 

Magic was fading in the world. Dragons, once the rulers of the earth, now were unable to defeat peasant farmers, let alone knights. The only explanation for this was that magic was becoming weak, and so must the dragons. In desperation, the dragons searched far and wide for an answer to the problem, and in one dungeon, may have found it.

Aghergoisk was living in strange times. Her ancestral memory, filled with visions and memories of draconic supremacy for...forever. Before humans, elves, and the other lesser races had come into prominence. But now, even the peasants had the means to defend themselves against dragons. These so-called fire-arms. No dragon was completely sure how they worked. It was a metallic cylinder pointed, barked a loud noise at what they were aimed at, and inflicted damage. Their magic, proving insufficient. The source of their power was dwindling. They needed...something new. And sure enough, while magically disguised in a nearby human city, Aghergoisk heard a rumor. An old ruin, nearby, housing great magic power. Could this be a lead? Something to get Aghergoisk recognized as the great savior of dragonkind?

Images flashed in the young dragon's head of glory and prestige. Celebrated by other dragons as the savior of their race, and she grinned at the thought. Even if it turned out to be nothing, she still wanted to be optimistic. At least it would be an adventure.

Following up on this lead, she inquired about nearby legends and rumors, trying to zero down the location of this old ruin. Once she found what she was looking for, or rather what she thought she was looking for, she quietly slipped out of town, and towards the old ruins, going by flight, once she was clear of any witnesses.

As Aghergoisk approached the area that contained the dungeon, she noticed that she wasn't alone. Carefully examining the entrance was a Green dragon in Mithral full plate armor, and with her were four Kobolds dressed in chain shirts and armed with long and short spears. She looked up as she heard Aghergoisk, and her eyes narrowed. "What are you doing here?" She demands. "I am Lese, and I suggest you move on."

“Hah, why would I pass on such glory?” The silver dragon said as she landed, preening. “I am chosen by fate for the salvation of our kind, both metallics and...uncloth chromatics. I am Aghergoisk and I am entering those ruins, whether you join me, or get out of my way.”

Lese's eyes narrow, but then she smiles. "Perhaps I was a bit too hasty. Perhaps joining forces is the better move. In fact, I'll even let you lead the way." She says, moving to the side.

Aghergoisk smiled, and proceed forward. “You won’t regret this.” She said, though she wasn’t a COMPLETE fool, expecting betrayal at some point.

Lese was more than happy to have the silver dragon lead the way. If she set off all the traps, all the better for her and her kobolds. All the other greens told her that being nice to the little creatures was a waste of time... but she couldn't help herself. As such, Aghergoisk would notice that the four kobolds were in surprisingly good shape, with nary a scar, and even well fed.

As Aghergoisk led the way, she found a chest in the first room. There was a glint of gold from under the lid.

Aghergoisk smiled on seeing the glimmer of gold, but her eyes narrowed. The odds of one adventurer, hunter, or even child wandering the woods never finding this chest was quite paltry. As such she was immediately suspicious, and took several steps backward, casting Mage Hand to lift the chest’s lid from a distance.

Despite her precaution, Aghergoisk and Lese are still plenty close enough to be knocked out by a powerful blast of magic that sweeps across the room, despite their magical immunity.

When Aghergoisk wakes up, she finds that she and Lese are curled up with each other in a rather compromising position. What's more, their wardrobe had changed. Aghergoisk is now wearing a simple diaper, all of her magical items have changed into more appropriate forms, and she is wearing baby cloths. (You can decide what it all looks like, the cloths do nothing for now.)
Lese's plate armor has transformed into a tight, form fitting onesie that shows off all of her draconic curves as well as her simple diaper, and her many accessories have changed as well. Her necklace has turned into a collar, her belt into a silk sash, her rings into plastic rings, and her amulet into a locket a little girl would wear. She is still asleep when Aghergoisk wakes up.

The silver dragon quickly scooted away from Lese as she came to her senses. She was quickly alarmed to see she was already wearing a diaper. Her amulet has turned into a metal collar, while her belt had transformed into a bow, wrapped around her waist. Finally, her vest had changed into a pink shirt, with short poofy sleeves, though her padding didn’t have the benefit of any coverage.

“Hey, wake up.” Aghergoisk tried to jostled Lese awake. “Something funny’s going on.”
