A filly named Pipsqueak

"Look, kid, I couldn't care less about what business you have going on down there, if Luna let you into this school in the first place, you must be something special to her. Besides, if you want to identify as a filly, who am I to argue? You are who you want to be."

Pipsqueak looked at Vinyl with wonder in his eyes. "You- you aren't going to..."

"Of course not! What harm is you being a colt doing to me? None, that's what! And hey, at least with that diaper on, even if you do get 'excited' nopony would be able to look and think you're a colt."

Pipsqueak's face turned beet red. "Y-yeah. I really hope I don't have to use this."

"Nah, don't worry about it. I'll get the nurse to write you a note so you can go to your dorm early. You don't need to deal with much more embarrassment today. You'll only be required to wear the diapers in the halls of the school until the end of the week. School policy for having accidents. It's also policy that I have to give you this 24-pack of Silly Filly diapers. Sorry, but you aren't allowed to wear panties in the halls again until you've used all these diapers up. Again, I know it's embarrassing, but it's for safety reasons." Vinyl explained.

"Thanks, miss Scratch."

"It's okay, kiddo. And don't worry, your secret is safe with me." Vinyl reassured Pipsqueak.

Pipsqueak gave Vinyl a hug. "Thank you so much!"

"Really, it's no problem. I may be a party animal, but I'm still a teacher. It's my job to look out for my students and keep their problems between me and them. Given, of course, their problems aren't endangering anypony. Now then, let's get going, I need to make sure the other fillies haven't demolished the classroom while there's no teacher."

They both laughed at this as they left the room.

"Was everything alright?" Nurse Cat Scan asked.

"Sure thing, Nurse Cat." Vinyl responded.

Nurse Cat Scan looked at Pipsqueak, who's face was still red. "Oh sweetie, it's okay. It's happened before, you don't need to be embarrassed. Many fillies your age have accidents. Still, I'm so sorry you had to go through all that embarrassment."

Pipsqueak's face grew one more shade of red. "It's okay, I'm over that now. It's just..." Pipsqueak turned his head to the side a little.

"Oh, the diapers! I'm sorry, but it's school policy that you have to wear those. Don't worry though, nopony will see them, unless you want them to, though you will have to check in with me after every period to see if you're not wet or..." This time it was the nurse's turn to blush. "...Or messy."

Pipsqueak's face could not be any more red. Pipsqueak was embarrassed simply at the thought of pooping in a diaper like a foal. "I'll make sure I'm dry and clean every time I do come in."

The nurse chuckled before letting Vinyl and Pipsqueak go.

As they walked down the hall towards the dorms, Pipsqueak noticed his gut rumbling. "Um, Miss Scratch?"

"Yeah, kiddo?"

"I have to poop."

"Oh, well the bathrooms are all right he-" Vinyl stopped as she saw where the bathrooms were. "Out of order?!"

Pipsqueak's eyes started to water. "No. I don't want to poop myself like a foal." Pipsqueak started to cry.

"Kid, we're almost to your dorms, just try to hold it until we get there, okay? You can do it!"

Pipsqueak wiped the tears from his eyes. "O-okay."

The two managed to get to his dorm. "See ya tomorrow, kid. Hope you're feeling better by then. You take care, alright?"

Pipsqueak opened his door before responding "I will, miss Scratch."
