Dr. Binx, straight-laced and professional, finds himself in a compromising situation when a routine physical exam with a hulking jock turns him on. The muscular patient, unaware of the doctor's growing erection, continues to lift weights, his sweat glistening, and grunting with effort. Binx, trying to maintain his composure, struggles to keep his stiffening cock hidden. Suddenly, the patient's towel slips, revealing his massive, hardening cock. Binx's eyes widen in surprise, and his own erection tents his pants, giving away his secret desire.
