I'm a bondage lover and incorporate it into 99% of my sessions.
When it comes to cp I do enjoy mixing it up.
Sometimes my subs will be restrained heavily
sometimes they'll be restrained in more predicament bondage
Sometimes I'll keep them free... but put a pencil in their mouth or make them balance a cup etc on their backs/head/etc. If they drop the cup or leave bite marks on the pencil, there's extra punishment!
One of my favorites is balancing a die on someone while I play. If they let the die roll off their body... they get a punishment depending on what number it lands on

I prefer ungagged most times.
