Female led relationships discussion

I need some input, My current lock up started on September 2, after we amended our current contract, thus transferring more power to my wife. Locktober has been a fun and sensual journey with me sending her pictures of me in my (or her) femme lingerie while at the office. There have been some t&d and quite a few orgasms for her. This time it has been stricter than any previous lock up, and I have been horny pretty much 24/7. So far, all amazing. On the last day of October I was allowed to enter her, but not allowed to orgasm. She teased me a bit before I got to enter her. The sex we had was amazing. I was on the very edge for about 20 minutes or so. Withdrawing at just the right time to calm down a bit then at it again, we could have continued forever. I was rock hard and she enjoyed my arousal and frustration as much as I enjoyed her pleasure. Then It happened. I was very close, and withdrew. I felt it would be ok. But it wasn’t. Trying my best to calm down while out of her for several seconds I felt how my body betrayed me. I felt how the ejaculation came even though there was no stimulation. A month of build up forced itself out of me. I felt like a failure, and that I had broken the firmest of the rules in our contract. She asked me rhetorically what punishment I think I deserve. She doesn’t see added days of lock up, flogging or putting me in cuffs and chains as punishment. That in her eyes, is play and rewards. None of us are into humiliation, so that is out of the question. The worst punishment would be to stop playing our chastity game. I hope she don’t want that, I know I don’t. She wants it to be severe enough to teach me a lesson. I feel, that in order to keep our amazing game going I need to show her I am taking our chastity contract dead serious. In our arsenal of toys the thing I fear the most is our cane, closely followed by our Japanese nipple clamps. Is this he punishment I should suggest? She has also told me that her trust in my judgement (or will) to keep on the right side of orgasming is consumed, and that that she will need to find a way to manage that. PS. I have sent this message to my wife so that she knows my thoughts to comply with one of the upgrades of our contract. So she knows and can have her say. DS
