"What are you–" said the girl, stepping through the door. Inside, she found a sun-guard with his nose in a dresser drawer. "–doing?"

The pony started, bumping his snout on the dresser as he tried to withdraw, scattering delicates about the floor.

"N-nothing! I mean..."

The girl shut the door behind her, and when she did a delicate light came into being above the bed, illuminating the room.

"Wait, you're that human the princess has taken in." said the guard, rubbing his snout.

Is that what I am?

The princess had told her about humans and the world beyond the mirror. Apparently, every pony, princesses included, had a human counterpart there.

But where is my pony counterpart?

"Please, don't tell the the princess." said the guard, blushing and covering his eyes with his hooves.

He was sitting on his rump, his nutsack resting on the floor between his legs like a leather sack. His cock jutted upward from it, half-erect and leaning slightly forward.

"So... this is Princess Luna's bedroom?" asked the girl, moving to pick up one of the liberated garments. She held it up to the light and saw that it was made of black lace.

Is this Lingerie?

"I didn't realize ponies wore underwear." she said, delighted.

She rubbed the delicate article against her cheek, closing her eyes and savoring the freshly-laundered scent.

The guard watched with fascination, the sight giving his chub a growth spurt.

When she was finished, she lifted her skirt and tucked the thong in the waistband of her panties for safe-keeping.

Before the guard could say anything, she interrupts him with a question.

"Are you not worried the princess will find you here?"

"Princess Luna watches over the palace while Celestia sleeps. She won't return to her quarters until morning." he replied.

"In that case, you look like you could use some help with that." she said, pointing toward his leaning tower of cock.

"I’m ashamed you have to see me this way, but there is nothing to be done, unless you can cure infatuation."

The girl smiled, and the pony was surprised by the way the sight of her pink lips made him feel.

"No, but I can relieve some of the symptoms."

She grabbed a striped sock from the floor and examined it.

The Princess of the Night has quite the private collection. When does she get the chance to wear it?

She sat on the end of the bed, and gestured for him to sit next to her, which he did. His weight made him sink into the mattress, even without his armor, reminding the girl of the enormity of ponies.

She slipped the massive stocking over his enormous cock, tugging it all the way down to his balls.

He gasped, the sensation of the delicate fabric sliding down his shaft and the pressure from her fingers (though he did not know that word; what came to mind was more like 'claws,') unexpectedly intense.

She cozied up next to him and slipped her hand beneath his balls, cradling them as she began to stroke.

He didn't last long, erupting into the stocking with such volume that it began to seep through the fabric.

The girl pulled the stocking off and the pony suppressed a yelp as it scraped the hyper-sensitive tissue of his post-ejaculatory penis.

She let him be a moment, the reverberations of his release still flooding his body, making his cock twitch as his breathing began to steady.

"Does this sort of thing happen a lot?" asked the girl.

"It is not unheard of for a guard to have a crush on his princess," began the guard between shivering breaths, "but I am a unique case, for it is her sister that I pine for: the princess of the night."

The girl tilted her head, trying to make sense of what the pony was saying.

"I am a sun guard, and as such it feels as though I am betraying my princess not just by fantasizing about her younger sister, but by lusting after any-pony but her radiance."

The girl thought for a moment, idly playing with his cock and fondling her own breast with her other hand.

"I don't think the princess would hold a grudge just because you are attracted to someone other than her. I do, however, think she would be upset that you snuck into her sister's room and sullied one of her socks."

He had been looking into the girl's painfully blue eyes, which seemed to hold him in a sort of trance, but turned red and looked away as the realization of what had just happened settled upon him.

"Perhaps you ought to find a mare that can satisfy you. I don’t imagine that you can carry on like this for long." said the girl.

He didn't respond immediately. The thought had crossed his mind, but he had never stopped to dwell on it. He didn't know many mares outside the guard, and it was difficult for him to look at his fellows that way. They were not supposed to have their own identities, they were supposed to represent the breadth and power of the princess's will.

"I'll help you clean up." said the girl, slipping off of the bed. She collected the clothing with ease and returned it to the drawer, except for the thong and the used sock, which she stuffed into her cleavage.

I will have to take a bath after I return to my room.

"I hope you find what you are looking for." the girl said, and left the sun guard in the bedroom with his thoughts, padding carefully down the hallway toward her own room.

The sun guard thought about what the girl had said, about finding someone to satisfy him. She had shown him so much kindness, though they had only just met. When he finally returned to his post, all he could think about were the girl's pink lips and startlingly blue eyes.

Author's Note

I started another chapter before deciding that it should be further down the line, and so this one took a little longer coming out. I hope it was worth it.
