The Unexpected Outcome of My Experiment

I've been married for ten years now and we've had a wonderfully stable life. But last year, I started feeling like something was missing. It's not that our sex life was bad, it just felt a bit... routine. So I decided to take matters into my own hands and introduce some kink into the mix. My husband is very open-minded about trying new things, but I wanted to surprise him with something unexpected. I found an online DDLG forum and decided to try out being his Mommy for a weekend. The idea of me being in charge, making all the decisions, feeding him like a child and punishing him when he didn't behave was exhilarating yet terrifying at the same time. I explained my idea to him over dinner one night - just as an experiment. He agreed without hesitation. We spent that evening preparing for our weekend together, going through what rules would be put in place, and establishing a few ground rules for how we were going to act towards each other when we weren't 'in role'. Our kids had already left home for college so we wouldn't have any interruptions. Saturday morning came, and there I was cooking breakfast while he sat at the table like a child waiting to be served. We watched some cartoons together as if we were still dating, sharing our first date memories. Later in the day, I made him take a nap because 'Mommy needs rest'. He was surprisingly into it all - playing along with my direction and acting out his part as a child. Sunday evening came around and he had a bit of trouble following instructions when we went to the grocery store earlier that day. That night, as punishment for his behavior, I grounded him in bed without supper. Watching him pout and beg me to forgive him was both amusing and intense. Reflecting on our little adventure, it wasn't exactly what I expected. But there's no denying how much it has brought us closer together in a way that I never thought possible. It's made me feel like the boss of my own life again - something I'd been missing since becoming a mother and wife. Am I being an asshole for trying to spice up our relationship this way? Or was it okay as long as everyone consents? Let me know what you think.
