For some reason that cage scene has resonated with me ever since I read it. In the book it was his first night in the "facility" after going through intake processing (also very hot eek) The narrative mentioned that most trainers reserved a night in the kennels (what his situation was called) as punishment for bad behavior but that his trainer liked to use the technique right up front to drive home to the slave his new circumstances.

I'm a big fan of predicament bondage but there are often time constraints in trying to incorporate it into a pro session. Good (and safe) bondage rigging takes time and then depending on the severity of the position it takes more time for the sub to get the full experience.

It's also hard to strike just the right balance. The discomfort/pain can't come on too fast but on the other hand it needs to build to the point where the sub's suffering builds and he gets increasingly desperate to be let out. That's where interesting deals involving "would you rather.....?" get made. grin

Also, I've found over the years that a surprising number of pro Dommes don't have all that great a skill set when it comes to complex or highly restrictive bondage. Maybe it's the short session/time thing or maybe most customers are more interested in D/s, CP and other types of play?

For me, elaborate, effective and very real bondage is the foundation of everything else that happens in a great session. Hard to find a great practitioner but when you do it can be magic. grin
