A Trainer's Secret Kink

I've always been professional and detached at work. But lately, my feelings for Jane have shifted. It started with her coming in upset over a breakup, she called me Mommy for comfort. We bonded deeply over this. Soon enough, I began nurturing her like a mother would her child. Little did I know, it was the start of something more intense than either of us bargained for. The other day she let me spank her, metaphorically and physically, for letting down our routine. It was both exhilarating and terrifying. Now I'm struggling to keep this secret kink contained within these walls. Venting here, just trying to process my emotions.
