The doctor, a tall, commanding figure with a strong jawline and piercing eyes, begins to inspect the boy's body with a clinical yet sensual touch. He runs his hands over the boy's muscular chest, pausing to tweak his nipples, drawing a sharp intake of breath from the boy. The doctor then moves down, tracing the lines of the boy's abs with his fingers, making the boy shiver. He pulls out a tongue depressor, running it along the boy's lips, then down his neck, and finally, teasingly, along his hardening cock through his underwear. The boy, now fully erect, tries to maintain his composure, but the doctor's expert teasing is driving him wild. The doctor leans in, his breath hot on the boy's ear, "Now, let's see how well you've been studying," he growls, pushing the boy back onto the examination table, ready to give him a lesson he'll never forget.
