The Secret Room

I'm Sarah, and I've been a high school English teacher for seven years now. I never thought I'd find myself here, confessing something that I feel so ashamed of. It all started last year when I met Mark through an online DDLG group. He was searching for someone to be his Mommy figure and I... well, I found the idea intriguing. We agreed to keep things professional at school and private off-campus. That's how it began, with a strict set of rules and boundaries that I never thought would make me feel this way. But as time passed, something changed inside me. The dynamic felt so freeing, and my control over Mark... it was exhilarating. I should have known something wasn't right when we started meeting in the janitor's closet during school hours. But there was always a part of me that thought no one would find out, until they did. Last week, a student walked in on us mid-session and everything fell apart. Now I'm facing suspension and the possibility of losing my job. How could I have let this happen? More importantly, how do I explain it to everyone who looks up to me as their teacher? Am I the asshole here for letting things get so out of hand?
