A filly named Pipsqueak

This chapter will not focus on the fetishes from the previous three chapters, but the main events of those chapters will be referenced in a manner so that you will understand what happened, to a small extent.

Pipsqueak woke up later to Trixie throwing some trash away. That's when he remembered what he was wearing. With a blush he look under his skirt to find that he was wearing... a clean diaper?

"It seems you are awake, and you had a Great and Powerful accident yesterday, roommate. Don't worry, I cleaned you up, and your secret's safe with me." The narcissistic unicorn said. "You aren't the only one who's pretended to be something they were not. Then again, telling the truth would have actually helped in my case."

Pipsqueak's eyes watered a little.

"Oh please, don't start crying. There's nothing to cry about. I know you're scared but somepony from Ponyville once taught me that fear isn't something to cry at, it's something to laugh at."

Pipsqueak looked up at Trixie.

"Then again, that mare was a bit off her hinges, but she was off her wheel, and that's good, because that means that she and the wheel are no longer a thing and Trixie doesn't trust wheels, so Trixie trusts others who don't trust wheels."

At this, Pipsqueak began to look a bit confused.

"The point is Trixie understands. Trixie doesn't understand what it's like, but she understands, and she will help you through the next couple of weeks with this issue."

Pipsqueak smiled and hugged the mare. "Thanks, Trixie."

"The Great and Understanding Trixie will do her best to be there for you, roommate."

Pipsqueak then realized he hadn't actually told Trixie his name. "Um, my name's Pipsqueak."

"The Blunt and Observant Trixie finds that an appropriate name given your penis size."

"HEY!" Pipsqueak yelled, only the laugh at the comment. "Okay, yeah, it is a little small, but I don't really care."

Trixie smiled. "Good! The last thing Trixie needs right now is to help somepony else with their self-esteem issues. The Great and Powerful Trixie has enough self-esteem issues of her own."

"Trixie, how can I be sure you'll keep my secret safe?"

"Because Trixie has many secrets of her own, and she's kept them safe for many years." Trixie said with a wink. "How about Trixie treats you to some pizza tonight? Trixie wishes to make up for the fact that we've been roommates and we don't even know each other yet."

Pipsqueak smiled. "I'd like that."

Two months later

Pipsqueak had gotten used to the school routine, and thankfully never had another accident in class. He had just finished his fourth period class with Vinyl Scratch and was on his way to the cafeteria when one of the teachers for the advanced classes stopped him.

"Hello, young miss. May I speak with you for a minute?" The unicorn stallion said.

"Y-yes, Mr. Spark?" Pipsqueak responded.

"Follow me." he commanded as he led Pipsqueak into his classroom.

Once both ponies were inside, Pipsqueak noticed the blinds were pulled down, darkening the room. Before he could why they were down, Pipsqueak heard the door lock. He turned around and saw the teacher coat the lock with a magic barrier. Pipsqueaks face turned to one of horror as he realized something was very very wrong.

"Listen, Pipsqueak. I know your secret, and let me tell you something." Spark's face twisted into a disturbing smile that seemed to stretch across his entire head. "I have plenty secrets of my own, and I'm about to share one with you, little colt."
