My Secret BDSM Fantasy with My Professor

I'm in grad school and married, but there's this secret fantasy I've been harboring that I need to get off my chest. It all started a few months back when Dr. Thompson joined our department. She's brilliant, kind of intimidatingly so, and we have these intense conversations during office hours where she pushes me past my comfort zone academically. But every time we're alone, there’s this unspoken sexual tension that I can’t ignore. Recently, it got to the point where I couldn't suppress my thoughts any longer. One night, after a particularly challenging session with her where she made me stay late and really push through difficult material, I found myself thinking about how sexy and powerful she looked sitting behind her desk. The next day, I mustered up the courage to send her an anonymous note suggesting we meet for coffee, but instead of just coffee, hinting at something more adventurous. To my shock, she suggested a roleplay where I would be her student again, this time in a BDSM context, with her as the dominant figure. We arranged to meet at her place after hours one night, and once there, everything turned into a vivid fantasy come true. She wore these elegant yet strict black leather gloves, and as we got started, she was commanding and exacting but also warm and nurturing in moments. She had me tied up on the floor with silk ropes, making me call her 'Professor,' while she made me beg for release before allowing it. This is all so incredibly new to me, especially since I'm married and not used to being anything other than fully consenting partners in an equal relationship. Now that we've started this, I wonder if there's any way to incorporate more of this dynamic into my life without straying from my marriage. Should I explore this further with Dr. Thompson or try to find a safer outlet for it?
