I’ve been wearing a Mature Metal Watchful Mistress device since February 28, 2013. My mistress lets me out for release occasionally, and I get locked right back in. The cage is very comfortable for long-term use, but it has always allowed some movement on my part. Although I would never betray my husband’s trust by releasing without permission, the lack of total security has bothered me over time.
I’ve been looking into different options. One idea was securing a captive bead in my frenum piercing to the end of the cage; this worked well but put too much strain on the piercing for long-term wear. I also spoke with Mature Metal about their anti-pullout system, but reviews suggested the posts might cause discomfort, so that didn’t seem like a permanent fix either.
I noticed someone in our group using a KSD-G2 from a CB-Curve device. Here is what one looks like:
I had an old KSD-G2 lying around that I no longer use, so I retrieved it and sanded it down slightly to fit my device. Initially, this made the gap at the bottom of the cage too tight. After some thought, I found a better approach: I cut the CB-KS2 in half (removing the lower section) and smoothed all the edges. Then, I added a small washer on the post between the lock and the KSD on my Watchful Mistress. It fits perfectly now.
It is very comfortable for long-term wear—I’ve had it on for four days so far with no problems—and extremely secure; I cannot pull out at all.
I have to admit, for the first time, I feel that complete emasculation of not owning a penis anymore. My husband and I are both enjoying this new level of security in our chastity dynamic.
It seems you can’t buy CB-KSD-G2 units much longer, and the hole for attaching a CB-KSD-G3 is too large to work effectively on a Mature Metal device post. If you struggle with security or pulling out, using an old KSD-G2 might be worth trying.
I’ll share a photo of my modified KSD-G2 next time I am allowed out.
