“No!” Luna stopped in her tracks. “I shall not enter, nor will I let them enter in turn.”
“Enough, Luna! Everypony expects this from us, and I expect it from you, as you have demanded of me for a millennium. So, let us just go in there and please everypony. The sooner we start, the sooner we shall be done.”
“No! I will not do it.”
“It is the law!”
“I do not care!”
“Oh, my…” Celestia charged her horn. ”I remember the last time you stopped caring! Luna, are you still in there or will you force me into another millennium of loneliness?”
“What? Are you about to banish me again to the moon over this? How can you not see that I am the victim here?”
“Are you losing the fight against darkness again, my sister? Snap out of it, Luna! Do not let Nightmare Moon consume you and take you away from me once more.”
Luna sighed in surrender. “Oh well, at least on the moon I will not have to suck—”
“—You do not suck! You know that, do you not? When I look at you, I do not see a mare who is sucking.”
“Yet…” Luna scoffed.
“Surely that isn’t the true issue at hoof. Is it perhaps the Nightmare Night celebration that is bothering you again? You said you have put the resentment behind you for good.”
“No, you do not understand me. I grew to love Nightmare Night, but this… I do not think I can get over it.”
“Why all the calamity over such a trivial thing?”
“After a millennium of celibacy, I am thrown straight into the fray. Nothing about this feels trivial. Scarring is how I would describe it.”
“All we have to do is answer any questions that they may ask to the best of our ability.”
Luna’s ears perked.
“If something is too private for you, you do not have to expose yourself. There is such a thing as too much information, you know?”
“Wait, is that all that we do?” Luna asked. ”We just answer questions?”
“But of course! What else did you mean for us to do when you suggested the Law?”
“Trust me, there were other things that occupied my mind at that time than verbal tutoring.”
“I do not understand, Luna. You clearly wrote oral pleasing. What other meaning could that have besides tutelage?”
“I was a teenager when I wrote that…”
“So, what was it that you thought about in your teenage years?”
“You do not want to know…”
“Did I misinterpret your law? I am very sorry if I did, Luna. Let us do it as it was meant to be done. Just tell me how.”
“Well, I am not sure I should…”
“I am really sorry, sister. I have hoped that me showing you that I kept you in my memory all that time you were away by honoring the law would please you. I see I do not know you enough now as I did not know you then.”
“Actually, it is okay. I was never attached to this law to begin with.”
“No, It is not okay. I want to do right by you and your pre-banishment aspirations. Tell me how you imagined this law and we will adhere to its full meaning.”
“Well, when the law says that we need to satisfy one hundred guards, it actually means... It means… Ugh! What was I thinking…”
“Yes, It has been a long time since the banishment, has it not? Decades turned to centuries, and centuries turned into a millennium.
Let me know if it comes back to you, okay? If you remember, we shall satisfy the Law the way you imagined it when you were in your playful years..”
A sinister smile plastered on Luna’s face. “You know what, in for a bit, in for a buck! I remember it now.”
“Pray tell.”
Luna grinned. “It is not really pleasing if we do not put our whole mouth to work if you get my drift?” The darkened mare moved her eyebrows up and down as she looked at Celestia. “You better moisten your lips.”
“Wait… Are you actually implying that we should use our mouth to s...”
“That is correct!” Luna licked her lips. “I shall make you put the deepest parts of your throat to work.”
“I am not sure I am up for that, little sister.”
“It is the Law, and you shall obey it!”
“I shall do no such thing. I will do anything for my little ponies, but I shall not do that!”
Luna charged her horn. “Celestia, are you still in there or do I need to banish you to the sun for disobeying the Law?”
Celestia gasped, lowered her eyes then bowed her head. “Okay, I see the hypocrisy in me now… I tried to force the Law on you. It is only just that you force it on me in return. As a Princess, I must fulfill my duty, even at my own expense if it comes to that. We are but servants to our little ponies. I do not have the option to resist this, do I? I cannot go against the law. Nor can I go against your will.”
“Good!” Luna shut down her horn. “Now, let us go in there together and sing to them in the Great Hall! Let the oral pleasure commence!”
“Wait, sing?”
“But of course, what else would you have us do?”
“Nothing! Nothing at all!” Celestia uttered a sigh of relief. “Singing is nice. Let us go sing to them as you say and mean.”
