Yup. that would be one thing. To elaborate a bit on my idea, imagine the following:<br/><br/>The victim (I'll use Kanami as an example here) is restricted, either sitting in a chair or hanging from the ceiling, doesn't really matter. She gets hooked up to a machine that monitors her brainwaves and recognizes positive and negative feelings. Also she gets vibrating eggs stripped to her clit and nipples and a shock-cable at the back of her neck. Then she gets a visor and headphones and is constantly assaulted with visual and audible suggestions and every time her brain accepts them, the eggs will vibrate and give her a good feeling and so reinforce the image, if she rejects it, she will get a small electric shock. Throw in some drugs, one to heighten her libido and a caffeine drug so her brain definitely stays awake during those hours and you can pretty much leave her unsupervised for hours until you decide to see if she has learned the lesson.<br/><br/>I'd say whichever method is used depends on the person who is doing it and their preferences. Viscous people like Arroyo would probably whip rather then sit them in a chair while I think Amy would like her goods to be more or less undamaged.
