Spiked Ring for Chastity Wear

I’d like one of these right down the page, sitting second from the bottom.

Looks good. I'd love to give it a try too. It doesn't seem like the best option for extended wear, but it's perfect for play.

That looks quite intense. I've always been interested in situations where arousal leads to pain. They say the pain helps reduce the erection, but I'm not convinced it would work for me; with my POI in the CB3k, that wasn't really what happened... and if there's teasing involved... ouch.
