As I carefully prepped a new patient for the urinary catheter. The middle-aged patient shifted uncomfortably on the bed, his hospital gown tenting slightly. I kept my demeanor professional, explaining each step as I lubricated the tube and gently parted his legs, but when I eased the catheter into his urethra, his eyes widened and a deep groan escaped his lips. His cock twitched visibly, swelling to full hardness right there under the thin fabric, the tip straining as a bead of precum darkened the gown. He muttered an embarrassed apology, face flushed crimson, but couldn’t hide the way his hips involuntarily bucked just a little as the tube slid home, his arousal unmistakably throbbing in response to the intimate intrusion. Some patients just love a naughty nurse and show off their approval by standing at attention!
