That depends on the degree needed - the punishment needs to fit the crime.
I usually begins with a warning eg ‘if you don’t stop then I I’m going to punish you’. This also helps establish to what degree she wants to be punished. Ie if she is still bratty she wants it, but if she gets more bratty after my warning then I know she wants something a bit… firmer.
Some of my favourite ways:
- if she’s resisting a lot - use more restrictive bondage.
- if she’s talking back a lot - fill her mouth. Worn panties are a favourite.
- denying or less doing things I know they love eg orgasm control.
- certain impact play. A well timed and purposeful slap or hard pull of the hair… or both.
- maybe my favourite… objectification. Nothing is about her anymore, and now she’s just my object until I’m satisfied. I have my go to favourite things on this.
Depends on the sub, and what her kinks are, what she’s not into etc. It’s all play, after all.
