Yes.

You don't think you can manage putting a diaper on yourself yet, so you decide to accept her help.

"Uh, yeah."

Spinel beams, and quickly takes hold of your hands, though she seems weirdly gentle about it while she moves at blazing speeds. "O-okay! I'll make sure you're wrapped up nice and comfy. I'm honored, gettin' to be your re-introduction to diapers!"

Spinel's rubbery arms wrap around your waist, hoisting you up effortlessly and laying you down on the adult-sized changing table. As her arms let go of their grip, one of her hands takes the pack of diapers from yous. "I'll be taking that, sugar, eh-heh."

While a hint of nervous energy is present in Spinel's behaviors, she keeps up the playful, jovial vibes for the most part. Before you can ponder on it further, the rest of the supplies are out. Wipes, baby powder, and a diaper is even out of its package and unfolded.

"Do you wanna take your pants off yourself, or do ya wanna let Spinel do it?"

"O-oh, yeah I'll just..." You quickly start pulling at your waistband, not wanting to have this person you just met undress you on the first day. Spinel suddenly starts looking around with erratic eye movements, clearly not sure what she should be doing right now.

"You can look away if you want, until they're off," you tell her. She quickly turns to look at the other side of the room, nervously chuckling. "Yeah, I'm still not entirely sure what the normal human behavior is with clothes and nudity, sometimes."

"Understandable, honestly. It's normal to give a little extra privacy even when it isn't really needed or makes the most sense, so people at least won't get upset if you do."

Once your pants are off, you tell Spinel, and she turns toward you again, and makes quick work of diapering you, moving in bouncy, cartoony rhythm the whole time. Her hand lies flat on your front pinning the front of your diaper down while her other hand effortlessly tapes you up. She then does some jazz hands. "Tadaa! Your first diaper since before you were potty trained!"

You try not to blush too hard as you stare are your padded crotch for a moment. It's really soft.
"T-Thanks."

"D'aww, it's no trouble," Spinel responds, "You look so cute with a diaper on! I think you were born for 'em."
