Oh, soapy, you make me laugh . . . The errant little bad boy caught sneaking into Whole Foods and then a leather clad Domme waiting for him at the exit with a ruler. I know that's not what you said, but that is the image your post conjured. Thanks for that little treat today.

Regarding behavior modification. I would love more sessions like that. I seldom get them (maybe because I don't promote that I do them) but the ones I have done have been almost exclusively about weight loss. Typically they involve weigh ins and the sub either gets a punishment (things he hates) or a pleasure (things he loves) session as a result. The most elaborate one went on for months with a MindFuck event (those are CNC experiences that are meant to keep the subject on edge, confused and ever guessing at what is next) at the end. Thankfully he made his goal because a day long MindFuck of things he hated would have been brutal - at least for him.
