When Training Gets Personal

I'm a personal trainer at the gym, but I've got this secret side where I like to play Mommy. It's intense and it's not just about fitness, it's about discipline, love, and control. With one of my clients, we started role-playing outside our sessions. He needs guidance, protection, and strict care. We kiss softly, then I give him chores, spank his bare bottom when he doesn't do them perfectly. His eyes water, but it's mutual, consensual, empowering. He feels safe under my hand, even though the sting reminds him of how much he wants to please me. It's hot, tender, and raw, all emotions I don't usually allow myself in public. But here’s the thing, I'm starting to question if this is healthy. Is it normal for a professional fitness trainer to delve into such personal dynamics with clients? How do I keep my boundaries while still exploring these intense feelings? What should I do when he asks me to come over and be his Mommy just once more?
