A recent thread got me thinking about whipping in a lot of BDSM and tickling videos, and I've been meaning to ask this for a while seeing as how I don't really use whips that often. Here was the original question:
I'm not into feet, but I'm assuming the principle is the same if you're talking about bondage whips? Like the kind you see in some videos?
If that's the case, exactly how do those work? I'm not talking about the big ones that look like they'd leave a permanent mark, I mean the small-looking ones that look like Koosh balls that people use lightly but they apparently hurt a little. Anyone want to explain how those cause pain when used lightly?
