okay, enquiring minds have to know ...

how do on-line dommes punish their subs? I mean, you can't spank/crop/whip them, you can't tie them to the bed, you can't cuff them, in reality you can't even stop them having an orgasm, if they really wanted one.

There are things you can still do, like remove yourself from them for a while, or make them do something they don't want to do, and provide you with proof they did it, but what else?

I think I spend too much time with my subbie, we don't have to deal with this.

So, what's the worst punishment you've ever had, when your dom wasn't around?
