NOTE: This was my first attempt at writing a proper story. Having seen the movie (and the dungeon scene), I just thought that a young queen with so many responsibilities might want to let it go sometimes.
DISCLAIMER: The characters of this fanart story are NOT owned by me, but borrowed from a well-known movie. This story is FOR ADULTS ONLY. If you are offended by sexuality and/or nudity and/or bondage and/or fanart that puts well-known characters into a kinky context, do not continue reading. The advantage of using already known characters is that readers already have a mental image of the involved persons, and that their background does not require a lengthy explanation.
====================
Mildred peeked into the cell. Through the key hole, so that she would not be noticed. Inside the cell, there was Elsa, nude except for her stockings, her shoes, her blue opera gloves, and of course, the red burning stone dangling from the tiny silver necklace. Mildred and Elsa had agreed that Elsa should wear gloves to avoid marks from her cuffs on her wrists. The ones she was locked into now were special cross cuffs which firmly pinned together her wrists at a 90 degree angle. Even the flexible Elsa could not slide them down and bring them to her front. The cuffs were chained to one of the rings in the dungeon's walls, which allowed Elsa to move around a couple of metres. She had been there for almost two hours now.
Over the last year, these little visits to the dungeon cell had become a getaway and a retreat for the Queen of Arendelle. Once every couple of weeks, a small gap in her busy schedule opened, and if that gap was as large as an afternoon or even a day, Elsa would grab the necklace with the burning stone and take the secret way from her chamber to the dungeon. Mildred would await her in one of the cells, cuff Elsa's hands behind her back and chain the cuffs to one of the rings in the walls. Mildred would then leave Elsa like this for several hours or even for the whole night (checking from time to time if she was still fine), depending on how much time they had.
Every time the cell door fell into place and the heavy bolts barred it shut, Elsa did not feel like she was locked inside, it felt like the rest of the world was locked out. Whatever obligations there were, they were forced away and out of reach. It never took long for Elsa to drift off, letting go of all the responsibilities and worries that kept her busy in her daily life outside.
This time, however, something was different.
This time, Mildred could see that Elsa was not calm. In fact, she was restlessly pacing up and down the few steps that the chain allowed her, and Mildred could see from the look on Elsa's face that she was far from being relaxed.
Mildred quietly sneaked out of the dungeon's corridor and fetched another special pair of cuffs from the shelves at the entrance.
Elsa was indeed finding it difficult to calm down. She was trying to focus on her bonds or on the cell, but her thoughts kept returning to the big pile of paperwork she had left on her desk. The skies outside were uniformly grey, so there was not even that playful change of sunlight and shadow to distract her from her thoughts.
Suddenly, she heard steps. Immediately her heartbeat got faster and for a moment, Elsa wondered what would happen if she was discovered like this. She was relieved when it was Mildred who entered the cell.
"Are you back earlier this time, or is it that time does fly when you are having fun?" Elsa joked, trying relax the situation. Mildred had to smile and replied "It is the former, your Majesty. How have you been feeling?"
"Not good, Mildred, not good at all. I had made myself believe that I had time for a little retreat, but I have to admit to you -and to myself- that I was not being honest. I have to go through the contract and there are a dozen letters to write. Too much to finish on Sunday."
"You have finished more work than that on a single day. Now that you are locked, if I may say, you might as well stay locked."
"You are right, but I would rather have these issues finished. I should have finished them before I came down here. Would you be so kind and release me?"
"Not yet. I am not here to unlock these cuffs, I merely came for a small adjustment."
She stepped behind Elsa and released the chain from the wristcuffs, but only to lock them directly to the ring in the wall. She then knelt down and fitted the other cuffs around Elsa's ankles. "These come from Ireland, they are called 'Irish Eight Cuffs'". Elsa looked down and noticed that they indeed looked like the number eight. They were wide and rigid, pinning her ankles close together.
"This is better" Mildred said, then she turned away from Elsa and left.
Elsa wondered why Mildred had bothered rearranging her binding. The ring in the wall was at a convenient height, so she could stand quite naturally. Elsa started to explore her mobility, which -not surprisingly- was very restricted. She could slide her wristcuffs along the metal ring, a few centimetres to each side, but that was about it. She briefly, just as a little test, tried to break the ankle cuffs with her magic ice, but the red glow and the warmth on her bosom confirmed that the burning stone was still there, absorbing all her magic powers.
"This it not too bad", Elsa thought to herself, "but it might get quite boring."
It was not too bad for a couple of minutes.
After some time, Elsa subconsciously tried to relax one leg and shift her weight to the other, and instantly noticed how restrictive the anklecuffs were. She tried to find a more comfortable position, twisting her legs and hips this way or the other, but there was hardly any comfort gained. Elsa returned to standing straight.
