"If you stallions weren't meant to be castrated, then your testicles wouldn't be so easily removable," Princess Celestia huffed as I massaged her sensitive backside. "They hang low, allowing mares to easily grasp and severe them as need be. Am I not right, eunuch?"

I nodded. "Yes, your highness."

She smiled, her tail flicking some. "See? Take yourself for example. Were you uncut, you would not be expected to control yourself as you please me with those magical hooves."

It was true. I felt nothing as my hooves slid across and kneaded her plumpness. I had no ability to feel lust or any other romantic emotion. She was beautiful, this I could appreciate, but I felt nothing beyond a sense of appreciation. Were I whole, I would hardly have been able to control myself.

"I have always preferred the eunuchs," she continued. "My sister may enjoy enticing the gelding, but, until their entire maleness is removed, they remain... unsightly." She turned to look at me. "Eunuchs cannot be enticed with something as base as sex. Right?"

I shook my head. "No, your highness."

"The only reason we keep them geldings, is so that we may be satisfied when the stress of ruling gets too hard." She stretched her wings and pressed on a particularly sensitive part. "And it keeps us from... bearing unwelcome heirs. We warned our niece, Cadance, that marrying stallion was a mistake. Captain of the Guard, or not, I should have had him gelded. A vasectomy at the very least."

I made her moan with some firm pressure against her lips.

"Now she has given birth to an alicorn," she went on, sounding displeased. "Alicorns are supposed to be special, prove to be above the rest. Not born. How can we maintain our status if ponies think they can just birth the next princess. She is just fortunate it was not an alicorn colt. Such a thing must never exist. I fear she would not have had to decency to dispose of it had that happened."

She was not sounding happy, so I moved to massage her cheeks, really digging in my hooves.

"I even suggested she cut her husband, now that she has had the child she desired," she stomped her hoof against massage table, causing me to jump. "But, no, she has decided to keep the empire's longstanding law against the practice. The fools. Had such a law not existed, Sombra would never have been a problem. He would have been an obedient little eunuch, and they never would have disappeared for a thousand years."

I kept silent. My opinion was not needed.

"I have spent lifetimes trying to kill off this dangerous idea that colts are special," she growled. "A male's only purpose is to reproduce and pull the heavy loads. To give them dangerous ideas that they are meant for more is anti pony. Yet, even after all this time, only one third of the male population has been gelded. We need only twenty percent uncut stallions to ensure a viable population and military. Not enough mares have learned how much greater we are than our male lessers. Am I not right, eunuch."

"Yes, your highness."

"You don't sound convinced," she huffed. Whether or not that was true, it didn't matter. Princess Celestia simply loved the sound of her own voice. "Enough of this, clean up this mess and then follow me."

I quickly took a towel and whipped up the juices from her body and my hooves. Then she rose and began walking. I obediently followed.

She led me through the halls of the palace, mocking me with her divine marehood. I could feel no lust or desire, but I knew that I should. She loved reminding us of what she had taken away.

Eventually we stopped at a maid who was dusting a bust. She bowed to the princess respectfully.

"Good evening Broom Sweep," Celestia greeted her with a warm smile. "I hear your son is doing quite well in his studies."

The maid nodded. "Oh, yes, my little Stump Stomper is becoming quite the academic. The doctor's say he shall be quite the stud."

"That's wonderful," Celestia continued in her warm voice. "Though, it seems a waste of such a studious mind, don't you? Becoming a stud, his mind lost to mares, neglecting his studies."

The maid was silent for a moment. "Your highness?"

Celestia lowered her head until they were both eye level. "I've been looking for a studious little colt to become my personal eunuch. He would be provided with the finest tutors, with access to the royal library, and be raised to devote all his attention to the sciences. What do you think, Mrs. Sweep."

The maid gasped, a broad smile on her face. "Truly, your highness? O-of course. When do you want me to bring him?"

Celestia's smiled deepened. "Oh, stop working and bring him to the palace today. I shall have the royal physician's take care of everything. He shall be fit for service before the week is out."

The maid gasped and dropped her feather duster and took of at a sprint, crying for joy.

Celestia chuckled and looked back at me. "Do you know why I showed you this?"

I shook my head. "No, your highness."

"To show you that a stallion's only value is what the mares in his life can get out of him." She indicated the way the maid had rushed off. "That mother praised her son not just a moment ago. But, as soon as I offered her a way to gain fortune and renown as the mother of my personal eunuch, she jumped at the chance to have her little colt castrated. Remember this, eunuch."

As the surplus son of a noble family, I was destined to be cut from the moment of my conception. But a mother who had no such pressures or expectations was proof of what the princess had said. Her son would become one of us. Not even being offered as Luna's plaything first. And his mother was all too happy for her own good fortune.

I wordlessly followed the princess, awaiting her pleasures.
