Mistakes and Guidance Needed

My wife has been playing for six months now. Our chastity contract wrapped up a couple of weeks ago, and since we were both benefiting so much from it, we renegotiated for another two years. We decided to raise the stakes: instead of me being guaranteed an orgasm at least every other week (unless there is significant misbehavior), I no longer have any obligation to receive one. To ensure compliance, I’ve put more financial control and exposure agreements on the line if I break the terms.

It was really hot weather while we negotiated over dinner; it lasted two hours until we both got what we wanted. I printed off two copies, we signed them, and then cuffed myself ready for locking.

She had obviously been one step ahead because rather than putting my CB6k back on, she produced a custom fit Lori tube. It fits so well—too well—it is quite a bit narrower and shorter in length. I have always had a high libido and found that even with the CB6k I could get myself off; it took a while and wasn’t as fulfilling as a real orgasm but hell it relieved the pressure. The Lori tube is different though, I spent hours on weekends when she was out shopping trying to cum without success. To make matters worse, she said we are going for a new record of 1 month to celebrate the contract. She thinks I managed 22 days before, but in reality, I must have cheated four or five times during that period.

Should I confess? It feels like this might antagonize her somewhat. It has been five days and I’ve tried everything to reach orgasm but failed. There doesn’t seem a way around the device and I really don’t think I could handle another week, let alone another month; not sure what options I have.

Has anyone else had a similar problem? Thoughts appreciated?
