A Secret Guilt

I've always been the strict type when it comes to my students, but lately I've found myself drawn to a different kind of discipline with one particular student. He's 18+, and his curiosity about boundaries and limits has me questioning everything I thought I knew about authority and desire. It started subtly, late-night messages where he'd ask about rules and consequences. I never expected it would escalate into role-playing scenarios where I take on a protective but authoritarian Mommy role. When we're together, there's an unspoken agreement that my guidance is absolute. It feels wrong to enjoy the power dynamics so much. Am I going too far? Is this just part of exploring adult relationships and boundaries in an unconventional way?
