The Art of Discipline in Academia

I'm Dr. Evelyn Hart, a professor in my early 40s who's been teaching for over two decades. One might think that someone with my career and responsibilities would stick to the expected professional norms, but here I am, confessing something quite... unconventional. Last week, during office hours, I was approached by a student, Alex (25), whom I've known since his first year. We had an agreement, a sort of playful, yet serious mentorship where I take on a 'Daddy' role to guide him through academic and personal challenges. Now, let's be clear, this isn't about crossing professional boundaries; we're both adults, and it's strictly consensual. However, the recent sessions have become more... physical. After some heated debates in class, Alex was required to face a form of discipline that involved me tying him up with office chair belts and using my paddle on his backside. Yes, I know how absurd this sounds when written down, but it's our way of connecting and resolving conflict. My question is: Is this something others have experienced or considered normal? Am I just indulging in some twisted form of roleplay, or does this serve a deeper purpose for both Alex and me? Comments welcomed.
