The young patient's mysterious fever puzzles the experienced doctor. To rule out any unusual causes, she decides to take his temperature rectally. With a gloved hand, she inserts the lubricated thermometer into his untouched asshole, slowly twisting it as she pushes it deeper. The patient gasps, his body tensing as he feels the cool, invasive object in his most intimate place. The doctor, noticing his unusual response, maintains a professional demeanor, but can't help but feel a thrill at the forbidden nature of the examination.
