Rarity: "Sweetie Belle, I'd really just like to thank you again for helping me model my new line of diapers.
Sweetie Belle: "So problem sis, anything for you!"
Rarity: "Oh you really are too nice, it wasn't too embarrassing to wear diapers now was it?"
Sweetie Belle: *Shakes head smiling* "Nah, they're kinda comfy. I almost like them!
Rarity: "Oh my!"
Sweetie Belle: "What?"
Rarity: *Points at Sweeties flank* "Your cutie mark"
Sweetie Belle: *Watches as the cutie mark develops under her diaper's elastic* "Oh my gosh, oh my gosh, oh my gosh! What do you think it is?"
Rarity: *Trots over lifting elastic* "Oh dear, well how about that?"
Sweetie Belle: "What is it? What is it?!"
Rarity: *Weakly smiles* "N-nothing, I'll let you see for yourself."
Sweetie Belle: *Tilts her head to the side* "When?"
Rarity: *Smiles placing a hoof on her sisters bottom* "When I give you your first diaper change alright?"
Sweetie Belle: "H-huh?"
So Sweetie Belle is the last of three CMC (Excluding Babs) and I really enjoy Sweeties design in this! ^^
Anyhow, as always leave a request for which pony you want to see diapered next in the comments! I'd love to hear them!
I hope you all have a wonderful day! ~Oliver_England
