Introductions discussion

I’ve harbored the chastity dream for ages and finally found a chance to realize it. My wife knows I have a habit of watching porn, but she was convinced she didn’t like that about me. So, I suggested getting a chastity cage and explained that all she needed to do was keep hold of the key, and her answer was “ok.” That simple response really thrilled me! I knew it wouldn’t be an easy pitch since she is quite submissive and mostly vanilla. I didn’t push harder right away. A couple weeks passed, and I couldn’t wait any longer. One night, I asked, “I thought you were going to lock me in chastity so I’d stop watching porn?” I said it with a bit of humor but also eagerness for her response. She replied, “Well, I thought you were going to give me the key?” I chuckled and asked if she truly wanted it, and she confirmed, “Yes.” So, after letting a few more days pass, I decided to lock myself up and hand over the keys. When I gave them to her, she just said, “Oh ok.” My excitement was intense because I realized this was now real! She is very vanilla, so she isn’t fully immersed yet and doesn’t want to talk about it much. I told her we could drop it if it bothered her; we could forget about the whole thing. I also admitted that porn wasn’t the only reason I wanted her to keep the key—I wanted her to have a bit of control over me. Not much else was said, but she kept hold of the keys. To show my appreciation, I did more dishes for the next couple days and helped with our bathroom remodel. There isn’t any teasing or denial happening yet, mostly because we have two kids, which is fine by me. Her walking around in panties or leggings gives me a rise every day. Today, while the kids played in the living room, I lay in bed beside her and mentioned that being locked up was tough last night. She giggled and said, “I don’t want to hear it.” I asked if she would add time if I kept complaining. Her response? “If you keep talking about it, I will LOSE the keys!” This made me throb in my chastity cage! My wife gets regular orgasms with the vibrator I bought her, both when she’s alone and during sex. I’ve always loved going down on her because she tastes great and enjoy it myself; she also enjoys climaxing that way too. Our sex life is good, but finding time has been tricky with little ones around. I hoped this would bring out a dominant side in her, though that’s still being tested. As I type this, I remain securely locked and haven’t brought up the topic again. Can anyone offer insight on managing chastity with a submissive wife???
