This is one of the Night Actions in the game. The described effects may differ from those shown in your game depending on various factors, such as your Background, House, and Skills. Each night action has a corresponding skill.
This action has an Obedience requirement. If your slave's Obedience is too low, she will refuse to do this action. These actions have various levels. The name of this action may change based on your gender, Background, etc.
Time Taken: Variable
Note: This action will be done as many times as she's able if you don't select any actions at all and just click "do the planning" with an empty queue. You can use this to get around the Slut Maker background's inability to use this action normally.
Each night action has a corresponding skill associated with it. These skills have minimal gameplay impact at the moment, but they control what text shows for each action. Leveling up the skill will cause different texts to show.
