Nurse Redheart gave the freshly castrated colt a swat on the plot, sending him squealing back to his mother. The mare in question offered no comfort, seemingly frozen in place, her mouth again as her mutilated child hugged her legs, shivering with pain. She had just stood there and watched as the nurse strapped him down to a board, applied an extremely watered down anesthetic to his scrotum and cut away.

After a while, the socked mare herded the little gelding inside and shut the door.

Redheart then re-strapped herself to the mini medical cart and pulled it along to the next house.

Once there, she unhitched herself from the cart and trotted up to the door and knocked firmly. Another mare opened it. Well, she supposed, most of the stallions were out working about now.

She cleared her throat. "By order of their majesties, I am hereby authorized and ordered to castrate any males within this household who do not yet have their cutie marks. Do not resist. Pegasus soldiers are waiting in the clouds to apprehend all who oppose this royal decree."

She had spent all morning rehearsing those lines. It was fairly effective.

After some initial shock, the mare called out a name and an energetic colt quickly appeared by her side.

"G-go with the nurse," his mother encouraged him in a quite tone. He happily obeyed.

Redheart led him to the cart and bid him to jump atop.

"Lay down on your back, please," she instructed, indicating the padded board. He did as he was told. She quickly set about tightening leather straps about his body to keep him from moving and hold his hind legs wide open.

He struggled a little bit. "What's this for?"

"So you keep still," she answered. As she used tongs to extract some instruments from a pot of boiling water.

"Am I getting a shot?"

"No." Redheart then proceeded to dip a brush into a bucket of brown liquid. Then she began to gently stroke it upon his coinpurse.

"Hey. Stop that," he protested. "No one's allowed to touch me down there."

"I'm a doctor," Redheart responded, "I'm allowed to."

"Really?"

She just nodded as she applied a thin coat. Then she jumped off the cart to search for a stick while it set in. Upon finding a proper one she returned to the colt and promptly began poking his testicles with said stick. "Can you feel that?"

"Barely," the colt responded tugging uncomfortably at his bonds.

"Good," the mare responded. "Bite this, it'll help to."

After placing the stick in the colt's mouth she selected her instrument. A scalpel.

She was swift and precise, well practiced. She professionally shut out the foals screams as she cut two slits in the scrotum, pushed the testicles through the openings, tightly tied surgical about the spermatic cords, then sliced the cords rendering the colt a sterile gelding. Afterwards, she stitched him up, unbound him and swatted him in the direction of his mother.

This one actually made an attempt to comfort her son before taking him inside to rest.

Then it was off to the next house. Same routine. It seemed to be only mares answering the door this particular day. And she watched all of their expressions and reactions.

Most were in shock, having never actually witnessed the procedure. Some were horrified. A few even cried. But there were more than a few that were smiling and actually thanked her for what she did.

It was at the final house where it went wrong. Sugarcube Corner.

Confetti, cake, amongst other sugary delights, and blood was everywhere. The Cakes had resisted. Pinkie Pie as well. Redheart supposed she was part of their family in some way. The pegasus guards had swooped down from the sky and, after a long fought battle of party artillery and sugary treats, they were all cuffed and tied to posts outside their establishment to await justice.

Redheart obeyed her Princesses directions. All of the females in the house, the wife, the live-in guest/surrogate daughter, and the biological daughter all had their clitorises cut out and their labia deadened. After that, she used some sharpened clamps to nip their mammary glans off. Then it was the father's turn.

"Mr. Cake," Redheart kept her voice even as she reached between his legs and pulled his balls taught, "for the crime of civil disobedience, you are to be gelded along with you son. No anesthetic is to be administered to either of you. Just remember, you could have saved your son this pain if only you had obeyed."

Using the burdizzo, she slid the cold metal over his sensitive flesh, hovering it over one of the precious cords, then began slowly applying pressure until she heard the tool click. All the while the yellow stallion shrieked in pain for the whole town to see. The next cord crushed rendered him sterile.

"P-please, no," Mrs. Cake begged as she saw the nurse shift her attention to her little colt. "Leave him be. He hasn't done anything wrong."

"But you did," Redheart answered back as she proceeded to draw out the colt's testicles.

Even Pinkie and Mr. Cake were yelling at her to stop. But she had a duty to fulfill. Pound Cake's face was wet with terrified tears as the the mare proceeded to do to him what he had just witnessed her do to his father.

"D-d-dont," he pleaded in a small voice.

Redheart paused a moment and looked him in the eyes. "I'm sorry."

And another gelding was made.

Sometime later and back at her office, Redheart sat down on a chair and opened a drawer under her desk. She pulled a pistol, a simple snub-nosed revolver, fully loaded and just a high enough caliber. Taking a quick shot of some whiskey she had in another drawer, she placed the barrel of the gun against her head.

"C-come on," she urged herself, hooves shaking. "C-c-can you do it this time y-you horrid b-bitch? Filthy coward. Obedient whore... monster. Just do it."

...

...

...

...

Knock-knock.

Realizing she had been holding her breath, the mare took a deep breath and reluctantly replaced the pistol back in it's drawer. Saved by the bell.

"C-come in."

The door opened to reveal one Tempest Shadow. One of Celestia's top agents.

"To what do I owe the pleasure?" Redheart inquired behind a forced grin.

The hornless unicorn wordlessly closed the door behind her and took a seat across from the nurse. She silently took the whiskey bottle from off the desk and drank some of it.

"Cheap year," she commented after she had taken her fill. Being the whole bottle. "I am here by Celestia's order to seek out members of the Hidden Railroad. We have some things to discuss, Ms. Redheart."

Redheart stole a quick glance at her special drawer and sighed wearily. "Alright. What's my part?"
