The most efective dominance games are the ones where the sub is kept guessing. Agree upon absolute limits wel beforehand, and keep a safeword handy (preferably one that is intelligible even through a gag). But within those limits, keep the sub guessing.

For example, when I do play spanking games, I often set up a regular rhythm with what ever instrument I'm usiing, and every now and then will pull as the last minute and not make contact.

You might try bindfolding her and giving your self freedom of movement around the bed/bench/chair/etc and using physical touch to tease. Never let her know what's coming next This can be done with touch of varible level, anywhere from a light caress to a heavy smack. Heavyness of touch is pretty irrelevant.

I might have some other suggestions later.
