In the sterile, clinical environment, a handsome, uniformed doctor meticulously prepares a catheter for insertion. The patient, a rugged, muscular man, lies back, his body tensed with anticipation. The doctor's gloved hands expertly guide the catheter tip towards the man's urethra, applying the perfect amount of pressure. The patient gasps, his cock twitching as the catheter slides in, inch by inch, until it's fully lodged. The doctor, his eyes locked with the patient's, begins to slowly pump the catheter, drawing out a stream of piss, the man's body shuddering with each stroke.
