Actually making a man watch as you 'punish' his girlfriend is an incredibly
erotic thing.  The natural desire for a man (any man - cuckold or not)
is to 'protect' his partner if she wants to be protected or not.
The 'guilt' in having to watch (especially if he likes watching - despite
himself) leave the man in a very confused state and if you are sadistic
like me you will tend to enjoy such things!
Anoher 'scenario' is to punish him, so he knows what it feels like and 
then tie him up and make him watch you do it to her
