There's a huge difference in how my girl receives maintenance spankings and punishment. If she knows I'm unhappy, the punishmennt is so much harder on her psyche.

But it in no way detracts from the enjoyment I get (and presumably her as well) from the daily spanking she gets each morning concurrent with the removal of her overnight sleeping cuffs and collars. I always get up giving her the spanking and often made her late for work. (This was our summer routine btw. I'm home again for the winter.)

For you, I think if your punishments are framed as corrective vs. punishment for misdeeds, you can get the same joy from them without forcing your master to somehow differentiate between play and punishment.

In other words, he can spank you because he enjoys it, he can spank you because you can't quite get things done to his satisfaction (and he can keep raising the bar to keep you both happy) but real punishment, for direct disobedience, should not be something you aspire to, imo.

And now, rereading your question, I think that would be perfect. Punishment, not for being bad but for failing to meet his ever-increasing performance bar.

I'd give you the task of presenting your ass for a spanking in that oh-so-perfect standing, bent at the waist, grasping your ankles, posture that makes men hard. Of course, he'll have to whip that ass until you get it just perfect. Back not arched correctly? Ankles not grasped low enough? Butt cheeks clenched... or not? Each will get you swatted. Fix one but lose the other doing so? Swatted. Pretty soon you'll not have any issues with the punishment not being "real" enough.
