Rules a Sub can use:
If I make you worship my body (feet, armpits, balls, cock) I roll 1D4 and you are my bitch for that much turns. You can only use worship actions or have to skip your turn.
We can also use the usual Bondage/Hypno rules:
Flip a Coin to get free from Bondage/hypno on tails you get free on heads you have to skip.
