and even then it's not so much about causing pain as being in control. Bondage, domination, sadism, all about controlling the other person's comfort, position, emotion... sex comes after you're in controlthis also works really well
no force required so it doesn't tire out your arm, effect ranges from mildly uncomfortable to horrifying agony, depending on where applied
That's the plan. Not today though.Bro sand, stain and poly that shit.
