Caught In The Moment

I was at the gym after a late-night workout session when I ran into Sarah, an ex-client who now works as a massage therapist. We've been seeing each other casually for months, but she doesn't share my kink, CNC roleplay. Tonight, we ended up in a secluded corner of the locker room, and despite our usual boundaries, something about the steamy atmosphere, the dim lighting, and the tension between us got to me. I initiated the CNC scenario, and though it was clear she wasn't comfortable with it initially, there was an undeniable spark of arousal in her eyes. We ended up engaging in very explicit and graphic roleplay that had a profound effect on both of us. It felt like everything else fell away. I'm worried now about whether this is normal or if I should back off and focus solely on consensual activities within our established limits. What do you think?
