Why Does She Take It Off?

My wife allows me to take breaks from being locked up, though the one scenario I truly understand is when I need to fly. Passing through security with a metal cage isn’t practical, and she doesn’t want ANY risk of exposure, so she has me leave it at home. I see her point. There are other moments when she removes the cage for sex, satisfies my needs, and then puts it away again. Since I’m so content while locked up, I don’t understand why she doesn’t keep me caged even when “not in use.” We had a trip last weekend that involved several flights, so I was unlocked during that time. Afterward, I decided to lock myself back up and handed her the key the following night. She was mildly surprised but kept it. I plan to have a talk with her about keeping me locked more consistently. Perhaps she is looking for a break from teasing, but I haven’t been VERY calm regarding my needs and demands. Does anyone else have experience with their KH letting you out for reasons that aren’t obvious?
