Chastity and orgasm denial discussion

My wife and I have been incorporating chastity into our playtime, as well as using it for periods of discipline. She likes holding the key and has recently taken to teasing me before deciding not to let me out. Whenever I am putting on or taking off my device, she is always present. Her watching makes things tricky when locking up for obvious reasons. The other night, I was locked in. She wore a little black dress with black nylons, clearly signaling her desire to play without guaranteeing release. Before bedtime, she sat down and placed her stockinged feet on my lap, rubbing my cage with one foot while the other received a massage. Once we were in bed, she insisted I remain naked except for my cage and teased me intensely. Eventually, she commanded me to pleasure her using both my mouth and our dildo, resulting in a powerful orgasm for her. To my astonishment, she announced that it was time to unlock me and asked me to keep my eyes shut while she retrieved the key. Lying on my back, I felt the dildo being placed inside my mouth as she instructed silence. Then, surprisingly, she began to undo the cage. The sensation of her unfastening the lock and sliding both the cage and ring off was incredible. Never before have I been so sensitive; I tried to moan but had a full mouth. After setting the cage aside, she started caressing my highly sensitive cock. It became impossible for me to stay quiet. She removed the dildo and pressed her hand firmly over my mouth, gagging me as she gave me a handjob while telling me not to make a sound. Naturally, it ended quickly afterward. The experience was incredibly sexy, but the greatest thrill was feeling her unlock the cage with total control… I barely slept afterwards. I am unsure how others feel about this, but having your key holder physically take you out is truly unique!
