Doctor's Secret Desire

I'm Dr. Sarah Chen, a married physician at a busy clinic. Lately, I've been obsessed with a patient, Mark, who visits for routine checkups. He’s in his early twenties and has this rugged charm that draws me in every time he steps into the room. The tension between us is palpable but completely platonic... or so I’ve convinced myself until now. A few weeks back, while running late-night diagnostics on a separate patient, Mark walked in looking distressed, his usual calm demeanor rattled by something heavy on his mind. He confided that he was considering drastic steps to relieve stress, words and gestures that left no room for ambiguity about the nature of his distress. I found myself torn between my professional ethics and an overpowering desire to be there for him in a way only another body can provide solace. We ended up sharing a moment that blurred lines, intertwining desires as our bodies sought relief in each other’s hands and mouths, naked under harsh fluorescent lights, hearts racing as we whispered promises of secrecy and mutual pleasure. This is tearing me apart inside, how could I let this happen? How do I move forward from here without it affecting my practice or marriage? What should I do?
