Female led relationships discussion

I feel really bad about something that I did, and would like to get some of the mistresses opinions here. I’ve been locked in a CB-6000s since last October 2009. Since then my wife (keyholder) has let me out about four times. My last release was back in June when we went to Las Vegas. Since then I wasn’t let out, and I have been really horny wanting release. Last week I was alone at home because my wife was working late, so I decided to get one of her vibrators just to see what would happen. I placed the tip of the vibrator on the ring part of the chastity device, and it gave me the most intense feeling. I came in about 20 seconds. She doesn’t know that I came, and I feel really bad about it. I promised myself that I wouldn’t do that again. What do you mistresses think about this situation.
