Kim is experiencing a level 3 punishment. A level 1 is when I bind only her wrists. This allows for a reasonably comfortable position by only restricting movement. A level 2 is when I bind her forearms which constrict movement even more and is uncomfortable after a couple hours. A level 3 is when I bind her elbows together which is the most constricting while adding the element of forcing her to push her chest out. This position is uncomfortable the moment I tie her elbows together.
Of course there are more levels with other positions and punishments. And the length of each punishment is determined by what she did to earn it.
Since Kim here is already in a level 3 because she refused to prepare my dinner I think I’ll leave her like this overnight. Punishment is the only way your slave will learn.
