She agreed long ago to be a submissive to her Master...partly because it allows her to give up control and do what he tells her. Perhaps then her actions are not her doing, although she truly enjoys performing them.
The hidden cameras placed around the house capture her activities so he can view them at work. Some activities she's been ordered to perform and some she does as a treat for her Master while he's at the office. She can't help misbehaving in hopes of being spanked when he gets home.
Each day, she knows she has to check her email first thing in the morning. What surprise will he have for her to perform today?
