Secret Discipline Sessions

I never thought I'd admit this to anyone, but I've been engaging in a secret DDLG dynamic with one of my students who is now an adult. It started innocently enough, but over time we slipped into a role-play where I'm the strict Mommy and he's the little boy needing guidance. The first time it happened, I felt such intense guilt, it still feels wrong even though everything we do is consensual and purely for pleasure between adults. We meet in private places outside of school hours, and when we're together, there are sessions where I give him light physical discipline followed by comfort and care. It's thrilling but also terrifyingly taboo.
