Celestia and Luna were starting to feel bored. This was mostly due to a lack of new ponies to play with. The two did not wish to put the energy into an active search, doing so would attract the kind of attention they wished to avoid. Celestia had proven an excellent leader, convincing her sister to step down from her throne after an incident a few centuries prior. After some deliberation, it was decided that her title would shift from princess to queen, as anticipated this caused a buzz for a few years, but eventually died down when it was proven all that happened was changing the title for Equestria’s ruler. As for Celestia herself, she could feel the numbing touch of tedium on her day to day life, and her free time seemed to be lacking the relieving flow it used to.

There were times where she was almost envious of Luna, after the Nightmare incident Celestia had managed to convince her to give up her throne by citing that it could occur again at any moment and it would be best if Equestria’s populace does not see that side of her, of course, this also meant Luna was no longer in the public eye and had a lot more freedom to do as she wished on her terms. Add to that the kinky past times the two liked to partake in whenever possible and you could see how that could come close to frustrating Celestia, made all the more trying on Celestia when you took into account the apparent intimacy Luna had with one of the members of the inner circle the two shared while Celestia herself had yet to form any sort of connection like that.

Luna decided to do something about the boredom and headed to do the paperwork, that Celestia seemed always avoid, and get the towering piles of documentation. After she was mostly finished with the paperwork she felt a pair of firm hands begin to play with her L-Cup breasts. "Celestia," Luna gave out a deep erotic moan, "I really don't think this is the be..." more erotic moaning, "time for this!"

"Sorry, Luna," said Celestia, "but your cute plot and delicious rack sang to me to have fun with you." At that, the ivory alicorn teleported herself and Luna, minus Luna's outfit and Celestia's bathrobe, to Celestia's bedchamber upon her bed. Both had their large, shiny penises showing. Celestia's rod was flying at half mast and a rich pink, Luna's was black and still very soft.

"Not the time, Tia," Luna said before Celestia rammed her semi-hard rod into Luna's plot causing the midnight blue alicorn to scream in pleasure. Celestia started pounding Luna from behind faster and faster until the sound of the two slapping together and the cries of pleasure from Luna were all that was heard in the room. Luna could feel her dick getting hard, and felt awful about it, she should have had more control over herself. The act of sexual intercourse continued and got all the kinkier. First thing after getting Luna's dick hard was to stick an enchanted plug in it to stop the night alicorn from cumming. Celestia then pulled a dildo out from her private collection, one modeled after a minotaur's penis and rammed it up her ass. Celestia had always wanted a realistic dragon style dildo, but there was no dragon cooperative enough to allow for a cast to mold such a sex toy. After jamming things into herself her plot and Luna's dick she went back to fucking the other alicorn. This continued for a little over three hours.

The 'fun' was brought to an end when a notice was teleported directly into Celestia's line of sight. "Mmmm, that was good, little sister," said Celestia as Luna was lightly panting from minor exhaustion, "but have to get ready for court, which starts in about a half hour. How long did we last, this time?"

"Three hours, seventeen minutes and thirteen seconds," said Luna looking down at her dick flying at full mast like it was a traitor.

"Your time keeping abilities are impressive, mine seem to have lost their edge over the past decade or so. Oh well, 'obligations await. Oh, and don't take that plug out until after 'lunch', you can take a nap if you want though. Not that it will do you any good, that plug will keep your buildup from dissipating and won't let you release until it is."

Luna gave a groan, Celestia was really good at sexual torture and made the 'punishment' worse when her orders were disregarded. After lying on the bed for a few minutes to regain some more of her energy she teleported herself to her room and threw on a set of orange flannel pajamas before trotting back to the office she had been using for paperwork and resumed like she hadn't even been interrupted. All was going well until the clock hit noon, Celestia's usual time for lunch breaks and Luna felt a surge that would have been an orgasm only for it to be denied.

Luna moved through the halls to the dining area, as she did so she teleported her sleepwear to the top of her bed while also teleporting her own bathrobe onto herself. A quick check and tightening of the belt ensured the garment would be mildly presentable in the case of having unanticipated company. When she arrived Celestia was in a set of very revealing "royal" vestments. Luna just sighed as she sat down, and ordered a fruit salad and extra strong coffee. Celestia was in attire designed to make those she dealt with feel socially uncomfortable, again.

"Well, Lulu, it's nice to see you've selected 'appropriate attire," said Celestia as she finished her meal, "but since you're late that means you need to deal with the 'consequences', I do hope you are prepared." In a flash, she was behind Luna again with one hand massaging Luna's left breast while the other checked on Luna's corked phallus. The ivory alicorn grinned as she switched the checking hand to Luna's other breast. "Very good, you actually did as instructed this time, that deserves to be rewarded." Before she knew it Luna was no longer in the bathrobe, as anticipated when it came to Celestia, and now lying spread eagle style on the table, something less anticipated, with Celestia aggressively licking her pussy. A few minutes, of sexual agony, later Celestia positioned Luna's plugged dick directly at her own opened mouth and removed the plug and made a great effort to gulp down the massive stream of jizz. After licking her lips and looking about to make sure none of the spray from Luna had been wasted on anything other than her mouth Celestia said, "a delicious dessert as always, you should really look into that sort of profession."

Afteward Luna returned to wearing her bathrobe and sat down in her seat, just in time for the waiting staff to bring out her order, just as they were placing it before her Luna said, "I believe it's time for you to return to your duty, sister," said Luna, "I do believe there's a 'special' guest tonight." Celestia gave a worried face just before returning to her duties.
