Pinkie led the still dumbfounded dragon into the nursery, the blue walls surrounding the two as Pinkie closed the door behind them, locking it.

Pinkie bounced in front of the dragon, before looking him in the eyes.

“Okay, Spikey! Let’s get those big pony clothes off you!”

Spike’s eyes widened, before hastily backing up, trying to get some distance between him and the party mare, accidentally backing up into the changing table.

“N-No way Pinkie! There is no way I’m taking these off in front of you, or anypony else! Now please just let me leave!”

Pinkie, seeing how bashful the hatchling was, giggled to herself. Even though she changed his diaper plenty of times, he always got so embarrassed during them, which was just adorable.

“Okay, Spike. Let me help you then!”

Before Spike could register what she said, she became a pink blur, quickly going all over the teenager, before returning to her original spot, a rather familiar set of clothing in hoof.

Spike’s face went completely red as he realized what she was holding, and slowly looked down to confirm his fears.

Sure enough, the mare had stripped him completely naked, nothing but his scales staring back at him, and his rather impressive...let’s say asset, dangling between his legs, on full display for the world to see.

Spike yelped, falling back on the changing table, at which, strangely enough, some straps that weren’t there before were put around his waist, chest and arms.

“P-Pinkie? What are you doing, and where did these come from?!” The naked dragon asked, squirming around, as that was all he could do now.

Pinkie stood at the foot of the changing table, looking at Spike, though she wasn’t looking at the most obvious part of his body, instead looking him in the eyes again.

“Getting you ready for you diaper, silly! And those help keep you from falling off while I change you.”

She grabbed an unusually large diaper from under the table, as well as some baby powder. Spike blushed upon seeing that, like Discord’s diaper, it had a cutie mark on it. Or two, in this case.

The one he could see clearly was on the front, being three familiar gems, and another other one which Spike couldn’t make out at the moment.

His squirming turned into thrashing as Pinkie unfolded the diaper, first maneuvering Spike’s tail through a hole in the back, before sliding it up and placing the soft garment beneath his rear.

Spike blushed as Pinkie applied baby powder to his thighs, even lifting his legs in order to get some on his butt.

Spike slowly stopped his movement, as she taped the diaper over his waist, before giving the front a few pats, to signify it was over to the dragon.

Pinkie then pulled two baby blue mittens out and put them over Spike’s claws, at which the dragon tried (and failed) to pull his arms out of her grip.

“What now, Pinkie?” The embarrassed teenager asked.

“ Making sure you can’t take off your diaper again, Spikey!”

Spike was mortified at hearing this, as the only thing he was able to think of to get out of this at the moment was also getting taken away.

After putting them on, and making sure they couldn’t be pulled off with his teeth with yet another set of straps, the mare finally undid the ones on Spike’s body and stood him up.

As the dragon stood up, he saw a glance in a mirror on the door, blushing at the sight of himself clad in a diaper almost as big as what Discord was wearing earlier. He once again got a glimpse of what was on his rear, when Pinkie grabbed his claw, bringing the dragon over to a small playpen in front of the nursery door.

“Wait here, Spikey! Auntie Pinkie is going to get your cupcake!”

With that, Pinkie sped out, closed the door behind her, taking his clothes with her and leaving the dragon sitting on his diapered rump.

Spike attempted to undo the tape on his diaper, but sure enough, he couldn’t get a proper grip on them, no matter how hard he tried.

After a few moments, Spike glances down at the diaper, blushing at the sight of Rarity’s cutie mark on his front, before his attention was brought back to the one on his butt.

Spike looked around a bit, before his eyes rested on the only one his height and in his direct field of view. The one on the door.

Blushing, Spike moved his arms in front of him, his hands on the ground while his legs stood up, and began to slowly raise his tail.

“Okay, Spike, just a quick look, then sit back down and wait for a chance to leave.”

Once his tail was in the air, he braced himself and looked behind him, blushing upon seeing what decorated his diapered rear.

There, sitting proudly underneath the base of his tail, was Twilight’s cutie mark. The unmistakable red star covered nearly the entire back, the small white stars at the points almost invisible, but still able to be made out.

Spike let out a groan, facing his head forward and face palming.

“Right, Derpy called Twilight my mom earlier, of course that’s what’s on this thing.”

As Spike muttered to himself, he didn’t hear the doorknob turn.

“Okay, Spike, when she comes back you’re going to look her in the eye and-“ Spike was cut off by a sound.

“D’awwww, you’re so cute, Spikey-Wikey!”

Spike’s face went red, and he quickly turned his head to look at the door.

Pinkie had returned, the cupcake in hoof, her other covered her mouth as she sat on her haunches, the dragon’s diapered butt was pointed right at her, tail still raised up as he forgot to lower it.

Spike immediately turned and sat down, his face looking like a tomato, as he stammered.

“P-Pinkie! I-I’m so sorry, I d-didn’t know you were-“

Once again, Spike was cut off, this time by Pinkie quickly getting in the playpen, hugging the dragon.

Blinking, Spike awkwardly began to return it, not entirely comfortable doing so dressed as he was, not that Pinkie seemed to mind.

Pinkie then held the cupcake in front of him, it being a blue one with tiny gemstones in it.

Spike briefly forgot about his state of dress as he saw one of his favorite snacks, practically drooling as he skipped breakfast to return the scale polish to Fluttershy.

“Go on, Spikey, eat up!” Pinkie said, taking the wrap off the cupcake and gently putting it in his hands.

Spike immediately began to eat it, happily munching on the treat. Pinkie watched with a smile as Spike quickly devoured the cupcake in four bites.

Once he finished, Pinkie spoke up again.

“Spikey, guess who came in while I got your cupcake?”

Spike looked at her, confused for a moment, before his eyes widened as he remembered who Derpy went to get.

“It’s your mama!” Pinkie said, pointing at the door, as a certain purple alicorn entered the room.

Twilight was busy when she heard it, but the moment she got word that her hatchling somehow got out of the castle and got lost in Ponyville, she immediately dropped what she was doing, gathered some supplies and sped off to the Cake residence when Derpy said where he was.

Twilight immediately ran up to the flustered teenager, and embraced the diapered dragon in a tight hug.

“Oh, Spike! I’m so glad to see you’re okay! Don’t worry, mommy won’t let anything happen to you!” The alicorn continued this for a while, as Spike did the only thing he could think of for now, and that was yet another awkward hug, this one even more so considering who this was.

After a good two minutes, Twilight calmed down enough to start talking normally, and said.

“Okay, Spike, mommy needs to talk with Aunt Pinkie for a bit, so you want to play with the twins in the meantime?”

Spike’s eyes widened, his hug tightened as he remembered where they were. Back in the shop, next to the window in a playpen.

In front of everypony in the bakery.

Mistaking his tightening hug for a “yes”, Twilight broke the hug and looked her hatchling in the eye.

“Great! But before we do I got something for you.” Her horn glowed, and the bag at her side, which Spike didn’t notice at first, glowed as the first piece of clothing made itself known.

A bonnet, which was the same shade of blue as the mittens.

Spike blushed as it was levitated onto his head and was tied around it, not even trying to struggle as he knew she could just use her magic to keep him in place.

Twilight then brought out a pair of booties, which was fashioned around his feet in quick succession.

The final piece, and what Spike almost started to squirm around again because of, was a onesie. Namely, one that bore a resemblance to a sailor suit.

Spike whimpered, and raised his arms, having officially given up at this points, and it was brought down, fitting snugly around his body, and was secured on him, the flap on his butt being brought to the front and buttoned to the front.

After they were done, Twilight gently took his claw with her magic, and walking at his side, lead him back downstairs, with Pinkie following right behind them.
