The real world doesn't have protective spells, so if you're sticking your tongue up someone's ass (or are getting someone's tongue up yours) make sure you both know the risks involved and practice proper hygiene. Or use one of those protective membranes that almost no one seems to know about.

The Throne

It was late in the afternoon, almost evening, and the last rays of sunlight came in practically horizontal through the windows. The last few ponies still in the room were waiting for Princess Celestia to dismiss the court, as was protocol, but there was an odd, unusual tension running through them.

The pony sitting on the throne didn't fail to notice that. Certainly, some rumours about her activities had circulated. All as planned, really. Celestia had made sure to 'accidentally' let some bits of the plan slip, while talking to a guard in the gardens, just close enough to a group of nobles for them to overhear something.

None of them could know about the full thing, though. The white alicorn shifted in her seat, feeling the magically hidden pony's tongue swirling along the rim of her ass. She'd been at it all day long, and quite eagerly too. It was quite surprising that she was still up at it with the same vigour even after hours and more than one orgasm. Still, it could not go on forever. I think that's enough for today, the princess soundlessly said to the one whose face she was sitting on.

As you wish, Mistress, came the still soundless, magically transmitted reply of the mare in question. But her tongue darted a little deeper inside the alicorn, while her lips wrapped around her backdoor and suckled with renewed emphasis, revealing her reluctance to actually stop. Are you sure about it? Wouldn't you rather have me tend to you longer?

I am. "Court is dismissed," the alicorn spoke aloud, shifting a little again and letting a small groan escape her lips. She watched the blushes and uncomfortable expressions of the nobleponies with delight as they walked away, and started to practically grind her ass on her sister's face as the last of them closed the door. She did wonder if they'd seen her as they looked back to close it, and what exactly they were thinking.

After a few more second of intense grinding and fantasising, she finally came. Panting after her climax, the mare stood up and stepped down from her seat, then gave a flick of her horn. The air around the throne flickered. There, in place of the usual seat, was instead the tied up form of Princess Celestia, covered in sweat and panting from arousal. The magical disguise that her double had been wearing then lifted itself to reveal Luna instead.

The younger sister went to unfasten the bonds holding Celestia in place, unlatching the straps and belts one by one. Then she helped her get back to her hooves, wrapped her forelegs around her neck, and before the other had a chance to react planted a deep, sloppy kiss on her lips.

After a moment the kiss was released, leaving a strand of saliva connecting the two sisters' mouths. "Oh, Luna," Celestia playfully chided her, putting on a faux indignant inflection. "You know how unsanitary that is!" After saying that, she cut the bridge of spit with her tongue and lapped it up.

Luna just smirked back at her. "I'm the princess now, remember? I can do anything I want. Besides, you're one to talk." She dove in for another quick kiss. "And I do have protective spells in place. So, did you enjoy it as much as it felt like you did??"

Celestia nodded. "It was wonderful, yes. And you did a great job at impersonating me. Although..." A mischievous smile spread on her lips. "Maybe we could switch places for a day. You certainly don't seem to mind the taste, do you?"
