Yikes, spikes!

I have finally found a cage that I can wear fairly comfortably for more than a day. This has been a long and arduous process I will detail elsewhere.

My question du jour is this: My cage of choice does not come with any sort of spike ring or spiked add-on. There are times when adding some spikes would be... well, at least interesting. Are there any "generic" spike products of some kind that could attach to or around or over or through an existing cage?

If it helps, here's the one cage that works the best for me: https://lockthecock.com/products/st...ken-cage-design-with-catheter-chastity-device

I hate the name and I do not use the catheter. But the device itself works... well, the least bad of all I've tried. I have one small testicle that escapes like Houdini. This cage is really easy to put on, which I appreciate.

Back to the point, I'd love to attach a something with spikes through it that would provide a nice punishment for an erection. I haven't seen anything like that and figured if anybody knew of something like that, it would be someone here.
