Trigger warning: horse using a rock as a dildo
(I hope to dear god that isn't actually a trigger for anyone)

After uncountable days on the moon, Luna's bored. And horny. Oh, so, so horny. With nothing to do but remember the depraved deeds she committed as Nightmare Moon, she is in a near constant state of arousal. She's tried masturbating, but to no avail. It's just not good enough.

She needs something hard.

And long.

And salty.

And possibly a little rocky.

It may not necessarily be sentient, but then again, after her mind has been so thoroughly mangled, is she?

For, you see, this is not merely a story about a horse jacking off with a large, suggestively shaped rock. It is a story about all of us. About the human condition. About the pain of loneliness, the desperation of the heart, and how all of our actions, no matter how small, impact others.
