Up in Canterlot Castle, away from the events that were happening in Ponyville, Luna was pacing in her room, waiting for somepony impatiently.

Midnight Arc, the leader of the mercenary branch of the Canterlot Guard, and the last Dragonkin alive, was rushing down the halls of the castle, running as fast as he could to get to Luna’s room. Once he arrived there, he was stopped by the guards posted outside her room. “It’s ok guys, it’s me, Midnight. The Princess wishes to see me.”

The guards looked at each other and then nodded, stepping aside and opening the door for him. He dashed in quickly and looked up to the face of Luna, who looked disappointed. “Didn’t I tell you to be here 10 minutes ago?” Midnight nodded and looked down, sad that he had disappointed the Princess, and his master. He was Princess Luna’s pet. She didn’t force him, he just loved her a lot because of who she was and since she had seen the pet play pair she had thought that that was a new thing that everypony liked, so she wanted a pet for herself, and Midnight was happy to oblige.

She put a collar and leash on him and took the leash in her mouth, walking out the door with him behind her. The guards watched them in shock, being that they could still not comprehend that their friend Midnight was the pet of one of the Alicorn sisters. They walked through the castle until they reached the front door, exiting the castle and heading for Ponyville.

When they arrived, they walked around the town, so Luna could show off her new pet. She held her head up proudly as she walked with Midnight following her. After she felt like she had done enough showing off and presenting, they headed back to Canterlot. As they walked through the streets, some of the ponies looked at them in disgust, wondering why a Princess of all ponies would do such a disgusting thing. Of course, there was a couple that was secretly into pet play. They wouldn’t reveal themselves to Luna, but the fashionable pony and the delightful French flower of Canterlot looked at them smiling.

They arrived back at Luna’s room and she set down his leash, taking it off of him, but leaving the collar on. Celestia soon entered the room and saw the collar on Midnight. She sighed, realizing what Luna had done, since it was only a few weeks after the fair in Ponyville had happened. “Luna, did you make one of our guards your pet?” Luna turned around and looked at her sister and smiled. “I didn’t make one of our guards my pet, I made the one that loves me my pet.” She came up to Midnight and gave him a quick peck on the cheek, causing him to blush and nod. Celestia facehoofed and looked at them both, not amused in the slightest. “Luna, you do know you’re a Princess? Something like this won’t go unnoticed. It may cause a few ponies to get a bit awkward when around you.” Luna turned away from Celestia and rubbed her warm body against Midnight’s side, and he tried to cover his red face but his hoof was quickly brushed away by Luna’s soft tail.

“Well, sister, why don’t you get a pet as well? Maybe then others will see that it is actually pretty fun. What about one of your royal guards? Or your personal student, Twilight Sparkle?” Celestia was taken aback by what her own sister had asked of her. To make one of her guards a pet wouldn’t be a problem, but to ask her personal student? That would be out of the question! Why was she even considering this? She shook the thought out of her head and looked at her sister with a bit of anger. “I want this guard back on duty, ok? After he leaves we will discuss this matter more.” Luna looked up at her sister sadly, then at Midnight, and got an idea. As a Dragonkin, he had some special abilities that not even the Alicorn sisters could do. Luna could use that to her advantage to show Celestia just how much fun it is.

Luna whispered something to Midnight and he nodded, approaching Celestia. She wondered what the blue Alicorn had told the dark pony. Her question was answered when Midnight began licking Celestia’s neck. It felt good to the sun goddess, but she would have none of this. She was not going to be seduced by one of her guards. She pushed Midnight away, but he stood his ground, and walked back up to Celestia, removing his shades and tossing them to the side. His draconic eyes flashed and black tendrils rose from the floor, holding Celestia in a standing position where she stood. Midnight continued licking her neck, giving it a nibble every once in a while. Celestia tried to move, but couldn’t, and she was beginning to feel the effects of his treatment.

She tried to use her magic, but then a tendril came from the roof and wrapped itself around her horn, stopping the magic flow from being released. Another tendril came from the ground under Celestia and kept her wings against her body. Midnight continued his ministrations, now flying up to meet Celestia’s gaze, and she didn’t look too happy. He began kissing her and then went up and licked her horn. Celestia felt her horn get licked and felt a great pleasure, but held it back knowing why he was doing this. She was not going to break no matter what.

Luna smiled at her sister’s resistance, knowing it was futile since Midnight was good at what he does. Even if he was inexperienced, a Dragonkin makes for a very interesting partner. He went behind Celestia and brushed her tail with his hoof, nuzzling it, and then licking her royal plot. Celestia kept her tail low, not going to reveal anything. Another tendril came from the roof and wrapped around her tail, forcing it up. Celestia blushed, the red easy to spot on her white face.

She looked behind her at Midnight with an angry look on her face. “Midnight, stop this nonsense now! Don’t you dare touch anything down there!” Midnight looked at Luna, and so did Celestia. “Luna, tell him to stop, now.” Luna smiled and looked at Midnight, and then she thought about it for a bit. “Well, we could stop, but then you’d never feel the pleasure a pet can bring. Always doing what you ask with no complaints and no questions asked, and always wanting your love and affection. You would look good with one. Midnight, show her what I mean.”

Celestia looked at Midnight pleadingly, not wanting him to go through with this. He didn’t want to upset the Princess of the Day, nor the Princess of the Night, but the Night Princess was his master, and he must do what his master asks.

Celestia looked down in dismay, feeling defeated, knowing what was coming next. “Well, just don’t stick your you-know-what in me, ok?” Luna acknowledged her sister’s request and looked at Midnight, who understood, and held himself back a little so as not to become too aroused. He was good at following orders, though, so it shouldn’t be a problem.

He began licking at her plot again, and then down her legs, causing Celestia to shudder and begin to pant. He then nuzzled Celestia’s large white pussy, it being much larger than Luna’s due to Celestia’s larger size. It was also very warm, like the sun, but not so hot that it would burn his snout. He began licking and kissing the outside of her other lips until he finally penetrated her with his tongue. She gasped, feeling immense pleasure this time and not holding back. She was getting into it now and wanting more and more after every second that passed. She pushed against Midnight’s muzzle and stuck her tongue out of her mouth.

He started thrusting his tongue in and out of the Princess. She was moaning loudly now, causing the guards outside the door to begin getting aroused at the sounds, only imagining what was going on inside Luna’s room.

Every time he pushed his tongue in, he would kiss the outside of her pussy. Luna was now frantically clopping in front of Celestia. Wanting to please his master, another tendril came from the ground and pushed itself in Luna’s wetness, thrusting in and out of her. He had both Princesses in his grasp now, pleasing them both. He was now using his tongue on the Sun Princess, and his tendrils on the Moon Princess. Celestia finally came in his mouth, and he drank up all her juices. Luna was not far behind, and came all over his tendril. They were both panting severely, gasping for breath at the pleasure this one pet had brought both of them.

Midnight released the tendrils holding Celestia, and they receded into the floor and roof, both looking undamaged. He also pulled back the one in Luna, making it disappear with the others. Celestia turned around and looked Midnight directly in the eye, making him a bit scared. He kissed him though, and smiled, looking at her sister. Midnight was in a daze after what just happened. Celestia walked over to her panting sister and leaned down to her to kiss her as well. “You know, you were right, a pet is pretty fun, especially this one.” They both looked at Midnight, who was just sitting there watching them, before levitating his shades back over his eyes. He also sported an erection and tried to hide it. Celestia and Luna giggled at the sight, and Celestia walked to the door, before looking at Luna again. “You should probably take care of your pet; he looks like he needs some attention.” Luna nodded, and Celestia left the room. She heard the sound of Luna pouncing on Midnight and smiled.

She looked around, realizing the guards that were supposed to be guarding the room were missing. She heard some panting behind the nearby curtain, and walked over to it, moving the curtain. What she saw made her smile and chuckle. Both the guards were laying on the window sill, covered in each other’s cum, their cocks both flaccid.

She moved the curtain back into position and walked down the hall, a new desire in her heart. She wanted a pet, and she knew just who she wanted. She went back to her room and got out a quill, an ink well, and a piece of parchment. She
began writing on the paper.

“Dear Twilight,

I have something magical that may interest you. I would like you to come up to the castle as soon as you possibly can. I will be waiting in my room.

Your Faithful Teacher,

Princess Celestia”

After she was done she immediately mailed it and waited.
