A Lesson in Boundaries and Desire

As a professor in my early 40s with a strong affinity for DDLG dynamics, I have recently encountered an unusual situation that has left me seeking insight from others. A student of mine, whom we'll refer to as Alex, is someone I've always treated professionally and with the utmost respect. However, over time, our dynamic shifted subtly; my role as his academic mentor began to intertwine with a nurturing aspect reminiscent of a Mommy figure, something that aligns closely with my personal kink. Recently, during office hours, the atmosphere between us grew unusually charged. I found myself initiating an age-play scenario, guiding Alex into a submissive space, much like a son needing guidance from his mommy. It was consensual and explicitly framed as roleplay, but it made me question how far professional boundaries should be pushed even within negotiated limits. My concern lies in the balance between fulfilling my personal desires and maintaining the integrity of our mentor-mentee relationship. I am seeking advice on how to navigate this delicate situation moving forward.
