I guess I like the denial aspect, is the thing. There's nothing wrong with liking the idea of shoving a vibrator in her pussy and locking it in place, if that's your thing. But for me, whatever lights up the part of my brain that likes chastity belts, the locked in vibe doesn't do it.
Edging is fine, necessary even to keep those locked up pussies hungry for release, but it often doesn't portray very well in a single image.
I like images that focus on the girl's desperation, or that have her sexually serving others in ways that don't use her pussy. That pussy is locked up because you can't be trusted with it, young lady, but you're still expected to serve your betters who are free to cum whenever they like.
I'll see if I can find some more chastity images that are to my taste.
