The idea is:
Ariel wears shackles and slave collar, she makes the mistake of interrupting the football game you are watching Hywel, and therefore she should be punished.
In the dungeon, Ariel naked is tied to two spreader bars; the first bar, bind her neck to her wrists which are tied with a padlock on his back. The second bar is much longer, link the ankles to the wrists, leaving Ariel in a position strapado.
The punishment is severe, so for her to be most uncomfortable few toe cuffs are added and their thumb cuffs, and a gag.
After a while, the light goes out ………and ours imagination starts to fly.
