Remind your man that for right now he is your slave. Whisper this into his ear --
"Tonight you belong to me. You will do whatever I tell you and I am going to make you my bitch."
add a clothes pin to each nipple and say:
"you can have your turn to make me your bitch some time"
Pull his hair tightly
"but not until I'm done"
