Doctor's Little Secret

So, here’s a little story from my life as a doctor and a Mommy in a DDLG relationship. I’ve been married to my husband for over ten years now, but it was only recently that we decided to explore the dynamics of a Mother-Daughter relationship together. He’s forty-five and I’m thirty-nine, so both of us are fully aware of our age and capabilities as adults who consent to this kind of play. We started out slowly with some light-hearted teasing and joking around at home, but it wasn’t long before my husband began asking for more substantial forms of discipline and nurturing. He wanted me to guide him through various challenges, and he found solace in the idea that I would support him both emotionally and mentally as a strong Mommy figure. One evening, after a particularly stressful day at work filled with difficult medical decisions, I came home feeling drained. My husband sensed my exhaustion but also saw an opportunity to deepen our connection through our role-play. He wanted me to take on the role of his Mother more fully and discipline him for being too careless with his work emails earlier in the week. The evening unfolded with surprising ease once we began, and I found myself enjoying the power dynamics that came from disciplining my husband, now playing as a little boy who had acted out. It felt incredibly empowering to set clear boundaries while also offering love and support through his punishment. Afterwards, though, there was this nagging doubt in the back of my mind, am I crossing some invisible line by engaging so deeply in something that might seem immature or childish from an outside perspective? Is it okay for a professional like myself to indulge in such fantasies with someone as close to me as my husband? I guess what I’m really asking here is: how common is this kind of dynamic among adults who are both fully grown up and consenting individuals? Does anyone else out there balance dual roles like these in their personal lives, or am I alone in feeling conflicted about it despite genuinely enjoying it with him?
