I've caught a masked burglar breaking into my dungeon and I've got him cuffed and strapped to a wall. I take the rubber straps and pull them back, snapping hard across his chest. Now he knows I mean business. Let's see if a little "shock therapy" might be able to re-program him from his thieving ways. I take out my violet wand and begin zapping him all over his body. His chest, arms, stomach, and especially his cock and balls are zapped repeatedly. It's so satisfying to see him suffering for his crimes.
