Twilight was trying to remain calm throughout the diapering process. She hadn't ever had someone remove her panties like that. Pants was a different story since Pinkie loved to prank anyone. After it was taped up she sat up and stared at it. "Well this certainly feels awkward. So what are the rules?"

"The first rule is obvious, you have to use the diapee whenever you have the urge to go," stated Rainbow. "Number two, you must guide through this whole experience so we can learn."

"Wait I have to use the diapers? What? Why?" Twilight asked, not a fan of being dirty like that.

"Duh, how else are we suppose to learn to change a diaper?" Rainbow asked with a light chuckle. "Rule number three, you shall address us as mommy to Fluttershy and mama to me."

"Why do I have to do that? I mean I'm just supposed to be helping you through this aren't I?" Twilight asked confused.

"It's to get into character, dummy. Shesh, use your head, Twi," said Rainbow as Fluttershy removed Twilight's shirt and bra to fit in the baby role.

Twilight covered her modest B cup breasts. "F-Fluttershy! Give me back my shirt!" She whined, sitting naked except for a diaper. The only person supposed to see her naked was Cadance wand that was years ago!

"Sorry, Twilight. But before we can buy bigger clothes, you'll just have to go like that," Fluttershy imformed. She turned to Rainbow. "Maybe I should've ask you to buy that when you were at the store."

Twilight took her tshirt back and pulled it over her head. "I'm keeping my tshirt on. Cadance says I'm not supposed to show my breasts to anyone but my significant other and my doctor. A-and I'm kinda self conscious..."

"Alright fine, seems fair." Rainbow helped Twilight off the changing table. "So do you understand the rules?"
