Biceps flexing, the gym instructor commands his class, but his eyes betray him, lingering on the tight shorts and leggings. His own tight gym pants struggle to contain his massive, throbbing cock. As he demonstrates an exercise, his pants slip, revealing his thick, veiny manhood. Gasps fill the gym as clients catch a glimpse of the instructor's monster cock, tenting his pants. The instructor, flustered, quickly covers up, but the damage is done, and the gym is alive with the knowledge of his monumental bulge.
