Chastity and orgasm denial discussion

So this morning I was at about two weeks of lockup after a 6 week lockup that was part of almost 4 months of being locked up with only a couple releases for orgasms. I have always found the second week to be the hardest, and this morning was no different. My KH had woken up early leaving me alone in bed by myself playing with my locked penis with no relief when I decided to try my KH’s Hitachi vibrator. I’ve used it in the past but it’s never gotten me off, eventually it just ends up numbing me. But lately we’ve been doing this thing where she lies on top of me naked, both of us face up, and she uses the Hitachi on herself with me under her. It’s amazing if you can talk your KH into it, feeling her wriggle and writhe on you with full access to touch her, and no relief for yourself. My wife squirts when she uses the Hitachi so it’s also fun to feel her drip all through my cage as she gets off in a way my penis could never achieve. Anyway, feeling the vibrations through her body has been a real turn on, so this morning while she was showering I grabbed the vibrator, applied it to my jail bird, and expected it to just leave me worked up but more frustrated. To my surprise, in under a minute I had gotten off, without even getting hard in my cage. Now I’m in that post orgasm let down. I still haven’t told her, not sure if I should. We were going to go 8 weeks until Christmas, this would set it back till at least New Years unless she slaps a penalty on it, which she hasn’t been inclined to do (but I wish she would). So the real issue is now I know I can get off still in the cage. I’ve always known I could get out if I really wanted to, but she would know about that because I couldn’t get back in, but now I could go back to getting of several times a day without her knowing, which was the whole reason for the cage in the first place. Is there a way to prevent this? My first thought is just that we will have to find a way to lock the Hitachi up, which is probably possible. If I’m able to get off without getting hard I can’t see any belt stopping me. Thoughts?
