Anna giggled mischievously. She couldn't believe she was doing this. She couldn't believe Elsa was letting her do this. In Anna's hands she held Arendelle's scepter, the one used for Elsa's coronation a few months back. Below her on her hands and knees with her face pressed into the pillow was Elsa, completely naked. Her round, pale ass was stuck straight up for Anna's viewing pleasure. Those pale globes of flesh shined in the moonlight coming from the windows of their shared bedchambers.
Elsa wanted Anna to shove Arendelle's scepter, used for generations by their royal ancestors, as deep into her ass as it could go.
Anna still couldn't believe this was happening.
Anna had found that Elsa liked having an object shoved into one of her orifices. Stuck in her room during the throes of puberty had led Elsa to experiment with putting different things of all shapes and sizes inside her body. There was only so much she could do with her fingers in her pussy, so she abruptly decided one day to see what it would feel like to shove, say, an unlit candle in there instead.
Needless to say, Elsa was hooked after that.
Whatever she could get her hands on she'd shove either in her pussy or asshole. Pens, pencils, the handles of forks, knives, spoons, teapot spouts, etc. If it was long, thick and could fit in her with some effort, Elsa would love it. Maybe occasionally her mouth, but Elsa didn't want to choke on whatever she was thrusting down her throat. It would be embarrassing to be found dead in her room, naked, with, say, a rolled up piece of parchment in her throat.
When Elsa had brought Anna in on the fun she had found it felt much better for someone else to be doing the shoving. So for the past couple of nights Anna had been thrusting objects of different sizes into whatever hole Elsa wanted it in. Anna found it quiet fun to see the look on Elsa's face as she was fucked into climax by a rolling pin in the pussy she had swipied from the kitchens.
But this was something different. Shoving the scepter that had been with Arendelle's royal family for centuries into the reigning Queen's puckered anus felt… dirty. Especially since it was the Princess who would be doing the vile deed.
That just made it more exciting for the sisters.
Before she could breach Elsa's butthole with the golden rod, Anna leaned down and spat onto Elsa's tight little hole. Anna gave her sister's asshole a quick rimjob to get it nice and wet. Afterwards Anna used her fingers to widen Elsa's entrance. Elsa simply enjoyed the feeling of Anna's mouth and fingers on her ass, but she was eagerly looking forward to what was coming next.
Once Anna was satisfied that Elsa's anal passage was properly lubed and opened up she sat back to get into position. She grabbed the scepter with both hands and aimed it carefully at Elsa's butt. The hole was shining with Anna's spit and widened slightly by her fingers. Even still, it was going to be a tight fit.
Anna held the scepter with one hand on the shaft and the other on the orb on top. Slowly, she brought the tip of the end of the scepter to Elsa's ass. The tip pressed gently against Elsa's puckered anus. Elsa let out a gasp muffled by the pillow. Anna gave her sister a reassuring pat on the butt and started to slowly twist the scepter around, like she was screwing in a nail, until it slid inside Elsa's poop chute.
Anna started to push the scepter inside Elsa's tight little tunnel. She went slow; so she didn't hurt her sister. Meanwhile, Elsa groans could be heard even though her face was still smushed into the pillow. It was about halfway in before Anna decided that was deep enough. This was the longest object Elsa had inside her, and the furthest an object had gone. Elsa was absolutely loving it.
Anna started to pump the scepter back and forth. She'd pull it out until only the tip remained stuck in Elsa's opening, then she'd slam it back in. She'd use her fingers to play with Elsa's soaking pussy lips. She'd slap Elsa's big, perky ass cheeks and watch them ripple from the impact. Anna did all this until, with a tremendous cry of pleasure, Elsa lifted her face off the pillow to moan out her release. Elsa collapsed back onto, twitching from the aftershocks of her orgasam.
Smiling, Anna slid the scepter back out of Elsa's asshole. Unfortunately, the tip was slightly wedged inside Elsa's anal opening. Gripping one of Elsa's ass cheeks for purchase, Anna pulled the scepter free with a wet pop. Elsa cried out from the feeling of cool air rushing inside her shithole.
Tossing the scepter on the bed Anna laid down beside Elsa and hugged her close. They'd have to get the scepter washed and returned before anyone noticed it was missing. But, that was a task for tomorrow.
