Seeking Further Growth in Kink Participation

I wanted my wife to accept me staying in chastity, and she eventually did. I wanted her to personally enjoy the outcomes of it, which she does. She held onto the key for a while, keeping it where I could easily reach it. We agreed that she would wear the key on a gold chain around her neck. She also likes grabbing my balls and teasing me.

So what do I want? More! Now I’m considering how to get her involved in various kinks that arouse me, such as bondage and spanking. As I ponder this, possibilities seem endless. If she reaches the point where she’s willing to say yes to being tied up and spanked, I believe my mind will start wandering toward what happens next.

This bothers me a bit. Am I insatiable for kink, or is there a limit where I’ll feel balanced?
