Chastity and orgasm denial discussion

My wife is wicked…but in a good way. We have dabbled with chastity here and there for a couple of years, but nothing too intense or lasting an exceptionally long time recently. A few months back she locked me into our CB6000, and I kept it on for my longest stretch yet (roughly a month). I feel like I lack more self-control than the average guy because I went nearly mad; her teasing during cleaning didn’t help, especially when she mentioned that one of her girlfriends “thought it was adorable” to see me locked up. So yes, for us chastity is largely a game, though we might extend denial times down the road. By the end of that month, I really needed to release and cum. The special night came, and she unlocked my cage. It had been ages since I felt so hard; I was even pulsing slightly. That’s when she told me I owed her pleasure with my cock for ten minutes flat. If I climaxed early, the lock would go back on for a day per minute short. Usually my stamina is decent, but after a month of denial, I barely lasted one minute. It wasn’t as enjoyable as it should have been because I was fighting so hard not to come. I really didn’t want that extra time in there. Nine days later, I managed three minutes. A week after that, five. Then seven. This involved using every trick available: thinking of prime numbers and slowing my pace considerably. Three days later she teased me all day long. Instead of letting me set a comfortable rhythm, she demanded I “pound” her hard, then brought up the fact that her friend would like to see me in the CB6000—a claim I discovered was somewhat misleading this time around. This attempt lasted only two minutes. She is wicked, and I love her dearly; when I finally get out of this device, she’s going to be paying for it.
