If not pull-out-proof, are there any tamper-evident cages at least?

Yes, I initially had the same worries, but as long as it stretches (elastic) rather than tightens, it seems fine.

 

It could detect any arousal, or removal and report it to your keyholder via SMS.

"Why were you aroused at 10:47am today dear?"

 

Say nothing, it's a trap! Take the 5th! Oh wait, I'm from the UK and we don't have a 5th ammendment. Dang. Spill your guts! Before she does!

 

I tried your idea and it was okay but now instead of using elastic I am using a very fine necklace chain with two loose loops around my cock. Things are adjusted so that if I pull out then the loops are left inside the cage and because the chain is so fine they are too difficult to refit around mmy cock. So thanks for putting me on to a good idea.

 

I purchased this little device from Ali Express. It works with my resin and steel HTv3 devices very well, Once it is on pulling out is very hard if not impossible.
I am circumcised. The three soft little sticks touches the top of my penis. Once you try to pull the member out you feel their presence.
It really hurts. Otherwise it is very comfortable.
I don’t think that it is possible to remove it without unlocking it. Even somehow if I manage to remove it without breaking, it would be impossible to put it back without unlocking the device.

 

I rather like this idea. So much so that I'm just testing a modification to my own cage. I have a glans ring that will fit inside my cage if you insert it at 45 degrees. Once it is rotated back upright it's large enough that it can't be pulled out. So I've put that in the short cage I am wearing and I pushed my glans through it. When I reattach the cage back up to the main ring my penis is compressed and my glans is squished out wider than normal achieving a reasonably effective "head lock". I've tried pulling out of the back with a reasonable amount of force and it's doing its job.

It's one of these rings. Just a few pennies on Aliexpress

 

The easyer solution might be to seal both keys. Dor me it would be posible ro slip partly out of the cage but it would be Impossible to remove it completly while closed. No way to get the balls out of the closed keys. With thw keys sealed any opening would be noticed

 

Try a spiked cage, your not pulling out then!

 

What a great idea! I have the Lori's with retainer ring. It's good.... but not perfect. Pulling enough defeats it. And i can get back in with the sock method. But this might be the ticket.... A retainer ring plus a glans ring. There's no way i can get the glans ring on once I've gotten back into the retainer ring. Having a tighter retainer ring might block the urethra underneath. But having this open on the bottom eliminates that risk. The main issue I might foresee is the two rings pinching skin between them. Only one way to find out!

 

Why bother with a chastity device, you seem to have total self control, one would be wasted on such an angelic person, but us mere wankers need locked away from our self,

 

If you want real chastity take a deep breath and if need be close your eyes be a big boy and get pierced, once done you will wonder what all the fuss was about.
