Leave the following note for your man when he arrives home:
"Welcome home. For the next 12 hours you are my slave and are going to make MY fantasies come true. You are to obey every one of the following orders.
1. No touching yourself in a way that is pleasurable
2. Shower -clean yourself very thoroughly
3. Put on the chastity device I've left for you on the night stand. Use the padlock (ladies don't leave any spare keys around)
3. Once you're locked in your device I want you to insert the butt plug I left in the bathroom. Take as long as you need to get it in, then put on the lingerie I've left for you on the bed
4 when you have finished all of these instructions text me
