I haven't a lot of experience with these as it's not really my thing but I was wondering.......Is there such a think as a chastity cage that is truly inescapable? (Assuming the sub doesn't have piercings the cage can be secured to)

My experience is ALL are technically escapable. Just need to cut a lock.

Now, for pull-out, most trapped ball devices allow you to pull your cock out while still keeping it locked on the balls. That unfortunately lets you play then slip it back in. Especially if you are not super large. So you are essentially on the honor system. Piercing seems to be the only thing that prevents this.

Nope. A PA piercing is the only 100% sure way. That being said, some guys just fit better in certain devices and if the fit is really good, it does become very difficult to escape - but still not 100%.

Yes, that is kind of what I thought.

What about a spiked cock ring like a Kali's Teeth bracelet? I've seen them both with the dull prongs and with shorter, almost pin like sharp spikes. I would think one of the latter would be virtually impossible to slide off if it was locked on quite snugly?

The ones with teeth, you won't be able to keep on long due to irritation. They are for short term play only.

Got it. Thanks

Don’t you hate it when practicality gets in the way of fantasy?
