The boys, their youthful bodies on full display, are made to perform a variety of tasks designed to test their erection control, from simple breathing exercises to more stimulating challenges. The doctors, their professionalism faltering, struggle to keep their hands and eyes off the boys' hard, twitching cocks. As the examinations progress, the line between medical exploration and sexual gratification blurs, leading to a chaotic, messy conclusion that leaves everyone spent and satisfied.
